Description

Izum se odnosi na kolosječnu skretnicu, osobito na kolosječnu skretnicu velikog radijusa, kod koje se tračnice s jezičcem mogu premještati u dva krajnja položaja pomoću postavne naprave, u kojima se uvijek u određenom slučaju vrh jezičca prislanja na pridruženu glavnu tračnicu, pri čemu je na tračnicama s jezičcem smještena naprava za osiguranje položaja radi osiguranja položaja istih, koja ima najmanje jednu polugu s više krakova, i koja se hvata na tračnice s jezičcem, i može se okretati oko stacionarne osi rotacije, i opterećuje se pomoću akumulatora mehaničke energije, i može se pokrenuti pomoću tračnica s jezičcem, koje se mogu premještati pomoću postavne naprave, pri čemu pravac djelovanja sile od akumulatora mehaničke energije, posebno oblikovanog kao tlačna opruga, prolazi kroz oba krajnja položaja poluge na različitim stranama osovine okretanja. The invention relates to a track switch, in particular to a track switch with a large radius, where the rails with the tongue can be moved to two end positions by means of a setting device, in which always in a certain case the top of the tongue rests on the associated main rail, while on the rails a tabbed position securing device for securing the same position, having at least one lever with multiple arms, and which engages on the tabbed rails, and can be rotated about a stationary axis of rotation, and is loaded by means of an accumulator of mechanical energy, and can be actuated by means of rails with a tongue, which can be moved by means of a setting device, whereby the direction of action of the force from the accumulator of mechanical energy, specially shaped as a compression spring, passes through both end positions of the lever on different sides of the axis of rotation.

Osobito kod kolosječnih skretnica velikog radijusa, uslijed duljine i elastičnosti skretničkih jezičaca, nije zajamčen ispravan položaj tračnica s jezičcem u srednjem području, odnosno unutar područja skretnice. Stoga postoji i opasnost, da je u ovim područjima svijetli razmak između odmaknute tračnice s jezičcem i glavne tračnice premali za slobodan prolaz vijenaca kotača. Ovo ima za posljedicu oštećenje vijenaca, što dalje može dovesti do iskliznuća-Iz DE-AS 27 28 413 je poznata skretnica, kod koje se neprekidne tračnice u području skretnice savijaju u položaj glavnog kolosijeka ili u položaj sporednog kolosijeka. Ovo savijanje tračnica se dešava pomoću dvojih kolica za podešavanje, od kojih jedna djeluju duž staze paralelne glavnom kolosijeku, a druga duž staze paralelne sporednom kolosijeku. Pomoću ovih kolica za podešavanje mogu se također savijene neprekidne tračnice pričvrstiti na svakom pragu u njihovom odgovarajućem savinutom položaju. Especially with track switches of a large radius, due to the length and elasticity of the switch tongues, the correct position of the rails with the tongue in the middle area, i.e. within the area of the switch, is not guaranteed. Therefore, there is a danger that in these areas the clear distance between the offset rail with the tongue and the main rail is too small for the free passage of the wheel crowns. This results in damage to the cornices, which can further lead to derailment - From DE-AS 27 28 413 a switch is known, where the continuous rails in the area of the switch are bent into the position of the main track or into the position of the side track. This bending of the rails takes place by means of two adjustment carriages, one of which operates along a track parallel to the main track, and the other along a track parallel to the siding. By means of these adjusting carriages, the bent continuous rails can also be fixed at each threshold in their respective bent position.

Takvo ustrojstvo je međutim krajnje skupo, a također nije primjenjivo za kolosječne skretnice, kod kojih se tračnice s jezičcem uvijek prislanjaju uz pripadajuću glavnu tračnicu ili se od ove odmaknu. Jedna izvedba na početku spomenute vrste razabire se primjerice iz US-A 2 906 477. Kod ove poznate izvedbe smjeralo se na to, da se položaj prislanjanja vrha tračnica s jezičcem osigura na način, da se ovaj drži slobodnim od sila elastičnosti, pri čemu ovo treba biti postignuto drugim sredstvima, negoli pomoću opruge. U tu svrhu US-A 2 906 477 predlaže tzv. blokiranje u položaju mrtve točke. Time višekraka poluga treba zauzeti položaj zakretanja, kod kojeg krak poluge koji se preko šipke hvata na kraj tračnica s jezičcem, leži u ispruženom položaju, odnosno u položaju u ravnoj crti sa šipkom koja se hvata na kraj tračnica s jezičcem. Kod izvedbe te vrste niz problema ostaje nedotaknutim i također neriješenim. Naročito nije bez daljnjeg jasno i vidljivo, kako je bez dodatnih mjera moguće prekretanje, odnosno premještanje tračnica s jezičcem u drugi položaj . Ispruženi položaj, odnosno blokiranje mrtve točke vodi naime k tome, da se blokira takvo prekretanje krajeva tračnica s jezičcem. Premještanje se čini očito mogućim samo kompliciranim upravljanjem pobude kliznog pomicanja, kod kojeg se višekraka poluga najprije izvlači iz svog ispruženog položaja. However, such an arrangement is extremely expensive, and it is also not applicable for track switches, where the rails with the tongue always adjoin the associated main rail or move away from it. One embodiment at the beginning of the mentioned type can be seen, for example, from US-A 2 906 477. In this known embodiment, the aim was to secure the position of the top of the rails with the tongue in such a way that it is kept free from elastic forces, whereby this must be achieved by other means than a spring. For this purpose, US-A 2 906 477 proposes the so-called blocking in dead center position. Thereby, the multi-arm lever should take a pivoting position, in which the arm of the lever, which is gripped to the end of the rails with a tongue, lies in an extended position, i.e. in a position in a straight line with the rod that is gripped to the end of the rails with a tongue. With a performance of this type, a number of problems remain untouched and also unsolved. In particular, it is not clear and visible without further ado, how it is possible to turn over or move the rails with the tab to another position without additional measures. The extended position, i.e. the blocking of the dead point, leads to the fact that such turning of the ends of the rails with the tab is blocked. The movement appears to be apparently only possible by a complicated control of the sliding motion excitation, in which the multi-armed lever is first pulled out of its extended position.

Izum ima za cilj, da kod na početku spomenute vrste skretnica, zajamči ispravan položaj skretničkih jezičaca unutar područja skretnice, odnosno u srednjem području iste, a time i najmanji potreban razmak između odmaknutog jezičca skretnice i glavne tračnice. The aim of the invention is to guarantee the correct position of the switch tabs within the area of the switch, i.e. in the middle area of the switch, and thus the smallest necessary distance between the offset tab of the switch and the main rail.

Za postizanje ovog zadatka Izum se u biti sastoji u tome, da je unutar područja duljine tračnica s jezičcem, osobito u srednjem području istih, smještena naprava za osiguranje položaja, da je krajnji položaj poluge koji određuje razmak odmaknute tračnice s jezičcem od glavne tračnice, određen stacionarnim, od glavne tračnice odijeljenim graničnikom, koji se po potrebi može regulirati i koji djeluje zajedno s polugom, i da naprava za osiguravanje položaja ima dvije dvokrake kutne poluge, jedan krak kojih je zglobno povezan na jednu tračnicu s jezičcem, a drugi krak kojih se upire na akumulator mehaničke energije. Poluge naprave za osiguranje položaja drže se u dotičnom položaju preko akumulatora mehaničke energije, pri čemu se ove zadržavaju u ispravnom položaju preko zgloba na tračnicama s jezičcem. Ovaj ispravan položaj određen je graničnikom i kod velike elastičnosti jezičaca skretnice, jamci se odabranim položajem naprave za osiguranje položaja, da jezičci skretnice leže u ispravnom položaju unutar područja i u srednjem području, tako da je zajamčeno održavanje slobodnog prolaza između odmaknutih tračnica s jezičcem i pripadajuće glavne tračnice. Kutne poluge se preko prekretne točke premještaju pomoću tračnica s jezičcem uz svladavanje sile akumulatora energije, iza čega tada akumulator energije djeluje u drugom smjeru i pritišće poluge u drugi krajnji položaj, u kojem se tračnice s jezičcem opet drže u ispravnom položaju. In order to achieve this task, the Invention essentially consists in the fact that within the area of the length of the rails with the tab, especially in the middle area of them, there is a device for securing the position, that the end position of the lever that determines the distance of the offset rail with the tab from the main rail is determined stationary, separated from the main rail, which can be regulated if necessary and which works together with the lever, and that the device for securing the position has two two-armed angular levers, one arm of which is hinged to one rail with a tongue, and the other arm of which points to the accumulator of mechanical energy. The levers of the position securing device are held in their respective positions by means of accumulators of mechanical energy, these being held in the correct position by hinges on tongued rails. This correct position is determined by the limiter and with the high elasticity of the tongues of the switch, guarantees are made with the selected position to ensure the position, that the tongues of the switch lie in the correct position within the area and in the middle area, so that the maintenance of a free passage between the offset rails with the tongue and the associated main is guaranteed rails. The angle levers are moved over the tipping point by means of the tongue rails, overcoming the force of the energy accumulator, after which the energy accumulator then acts in the other direction and presses the levers to the other end position, in which the tongue rails are again held in the correct position.

Time, da je krajnji položaj poluge koji određuje razmak odmaknute tračnice s jezičcem od glavne tračnice, određen stacionarnim, od glavne 'tračnice odvojenim graničnikom, koji djeluje zajedno s polugom, i koji se u datom slučaju može namjestiti, određuje se pravilan položaj tračnica s jezičcem pomoću dotičnih krajnjih položaja poluge. By the fact that the end position of the lever, which determines the distance of the offset rail with the tab from the main rail, is determined by a stationary, separate from the main rail stop, which works together with the lever, and which can be adjusted in a given case, the correct position of the rails with the tab is determined using the respective end positions of the lever.

Pomoću, u datom slučaju moguće sposobnosti pomicanja graničnika, može se namjestiti pravilan položaj tračnica s jezičcem unutar područja, odnosno u srednjem području. Using, in a given case, the possible ability to move the limiter, the proper position of the rails with the tongue can be adjusted within the area, that is, in the middle area.

Svaka kutna poluga naprave za osiguranje položaja, koja ima dvije dvokrake kutne poluge, može biti uprta na posebni akumulator energije, koji je sa svoje strane opet poduprt na stacionarni ležaj. Takva izvedba kutnih poluga poznata je principijelno iz DE-AS 15 30 341. Each angle lever of the device for securing the position, which has two double-armed angle levers, can be fixed on a special energy accumulator, which in turn is supported on a stationary bearing. Such a design of angle levers is known in principle from DE-AS 15 30 341.

Pritom se kutne poluge ipak ne pokreću pomoću tračnice s jezičcem, koje se mogu premještati pomoću posebne postavne naprave, nego za skretnicu ove kutne poluge same tvore napravu za premještanje skretnice, sposobnu za namjerno pokretanje, koja se hvata na vrhove jezičaca tračnica s jezičcem. Premještanje vršaka jezičaca odvija se pritom pomoću elektromagneta, koji se hvataju na ove kutne poluge. Ove kutne poluge ne mogu stoga osigurati položaj tračnica s jezičcem unutar područja ili u srednjem području. At the same time, the angle levers are not moved by means of a rail with a tongue, which can be moved using a special setting device, but for the turnout, these angle levers themselves form a device for moving the turnout, capable of deliberate movement, which is caught on the tips of the tongues of the rails with a tongue. The tips of the tongues are moved with the help of electromagnets, which are caught on these angular levers. These angle levers cannot therefore ensure the position of the tongue rails within the area or in the middle area.

Krakovi obih kutnih poluga mogu biti također poduprti na jedan jedini zajednički akumulator energije. Kod premještanja skretnice obje se kutne poluge zakreću u različitim smjerovima okretanja. Točke podupiranja akumulatora energije pomiču se tako protusmjerno. Time se povećavaju kutovi, koji zatvaraju smjer sile akumulatora energije s krakovima obih kutnih poluga koje se hvataju na akumulator energije u krajnjim položajima istih, a obje kutne poluge se stoga s većom sigurnošću drže u njihovim krajnjim položajima. Ova povećana sigurnost je tada od bitnog značenja, kada se tračnice s jezičcem unutar područja treba držati u njihovom položaju isključivo pomoću kutnih poluga. Kod jedne takve izvedbe moraju kutne poluge biti smještene između kolosijeka, budući da one čak preko opružnog akumulatora energije zajedno djeluju. Kada je naprotiv svaka kutna poluga poduprta posebnim akumulatorom energije na nepomičnom ležaju, kutne poluge mogu biti smještene također izvan kolosijeka s obje strane istoga. The arms of both angle levers can also be supported on a single common energy accumulator. When moving the turnout, both corner levers rotate in different directions of rotation. The support points of the energy accumulator thus move in the opposite direction. This increases the angles, which close the direction of the force of the energy accumulator with the arms of both corner levers that grip onto the energy accumulator in their end positions, and both angle levers are therefore more securely held in their end positions. This increased safety is then of essential importance, when the tongue rails within the area are to be held in their position exclusively by means of angle levers. In one such design, the angle levers must be placed between the tracks, since they even work together via the spring energy accumulator. When, on the contrary, each angle lever is supported by a separate energy accumulator on a fixed bearing, the angle levers can also be located outside the track on both sides of the same.

Premještanje skretnice može nadalje uslijediti pomoću zaporne spone smještene u području vrha tračnica s jezičcem, a u jednom ili više međupodručja namjesti se sada pravilan položaj tračnice s jezičcem, pri čemu premještanje naprave za osiguranje položaja automatski uslijedi kroz same tračnice s jezičcem, bez potrebe za vlastitom pokretačkom napravom. The switch can be moved further by means of a locking clip located in the area of the top of the rails with a tongue, and in one or more intermediate areas the correct position of the rail with a tongue is set, whereby the movement of the device for securing the position automatically follows through the rails with a tongue, without the need for a separate drive device.

Na crtežima je izum šematski razjašnjen na temelju izvedbenih primjera. In the drawings, the invention is explained schematically on the basis of practical examples.

Slika 1 pokazuje pogled odozgo na kolosječnu skretnicu, a slike 2 i 3 pokazuju različite izvedbe naprave za osiguranje položaja gledano odozgo u većem mjerilu. Figure 1 shows a top view of the track switch, and Figures 2 and 3 show different versions of the position securing device seen from above on a larger scale.

Na slici 1 prikazano je cjelokupno područje skretnice u pogledu odozgo. 1 i 2 su obje glavne tračnice, 3 i 4 su obje tračnice s jezičcem. U području jezičca A, već prema položaju skretnice, prislanja se ili vršak jezičca tračnice s jezičcem 3 na glavnu tračnicu 1, ili se vršak jezičca tračnice s ,jezičcem 4 prislanja na glavnu tračnicu 2. Premještanje skretnice uslijedi na uobičajen način postavnom napravom koja tvori zapornu sponu i koja nije prikazana crtežom, koja se u području jezičaca A hvata na tračnice s jezičcem 3 i 4. Uslijed elastičnosti tračnica s jezičcem, kod skretnica s velikim radijusom, nije osiguran položaj tračnica s jezičcem unutar područja skretnice. Stoga je unutar područja, odnosno u srednjem području položaja skretnice odnosno tračnica s jezičcem smještena naprava za osiguranje položaja B, koja u ovom području određuje položaj tračnica s jezičcem. Figure 1 shows the entire area of the turnout in a top view. 1 and 2 are both main rails, 3 and 4 are both tongue rails. In the area of tab A, already according to the position of the switch, either the tip of the rail tab with tab 3 is attached to the main rail 1, or the tip of the rail tab with tab 4 is attached to the main rail 2. The switch is moved in the usual way with a setting device that forms a stop clamp and which is not shown in the drawing, which in the area of tabs A is caught on the rails with tabs 3 and 4. Due to the elasticity of the rails with the tab, in turnouts with a large radius, the position of the rails with the tab within the area of the switch is not ensured. Therefore, within the area, i.e. in the middle area of the position of the switch, i.e. the rails with the tab, there is a device for ensuring the position of B, which determines the position of the rails with the tab in this area.

Ovaj uređaj za osiguravanje položaja B je prikazan na slici 2 u većem mjerilu. Opet su s 1 i 2 označene glavne tračnice, a s 3 i 4 tračnice s jezičcem. Između kolosijeka na pragovima je pričvršćena ploča 5. Ova ploča nosi zakretljive osovine 6, na kojima su zakretijivo pričvršćene kutne poluge 7 i 8. Krajevi krakova 9 i 10 zglobno su vezani preko šipki 11 podesive duljine na tračnice s jezičcem. Krakovi 12 i 13 uprti su ,jedan o drugoga preko akumulatora energije 14, koji predstavlja tlačna poluga- U prikazu slike 2 tračnica s jezičcem 4 odmaknuta je od glavne tračnice 2, pri čemu je prolaz između glavne tračnice 2 i tračnice s jezičcem 4, označen s 15. Vršak jezičca tračnice s jezičcem 3 prislanja se na glavnu tračnicu 1. Krajnji položaj kutne poluge 8, koji određuje najveći prolaz 15 između glavne tračnice 2 i tračnice s jezičcem 4, određen je graničnikom 16- Krajnji položaj kutne poluge 7 određen je na analogan način graničnikom 17. Osovine 6 i graničnici 16 i 17 pričvršćeni su stacionarno na ploči 5, koja je pričvršćena na pragovima, koji i nisu prikazani. This position securing device B is shown in Figure 2 on a larger scale. Again, 1 and 2 are the main rails, and 3 and 4 are the tongue rails. A plate 5 is attached between the tracks on the sleepers. This plate carries pivoting shafts 6, on which angle levers 7 and 8 are rotatably attached. The ends of the arms 9 and 10 are hinged via rods 11 of adjustable length to rails with a tongue. The arms 12 and 13 are fixed against each other via the energy accumulator 14, which represents a pressure lever. In the view of Figure 2, the rail with the tab 4 is moved away from the main rail 2, whereby the passage between the main rail 2 and the rail with the tab 4 is marked s 15. The tip of the tongue of the rail with the tongue 3 rests on the main rail 1. The end position of the angle lever 8, which determines the largest passage 15 between the main rail 2 and the rail with the tongue 4, is determined by the stop 16- The end position of the angle lever 7 is determined on analogous way with stop 17. Shafts 6 and stops 16 and 17 are fixed stationary on plate 5, which is fixed on thresholds, which are not shown.

Kod premještanja skretnice, krakovi 9 i 10 kutnih poluga vode se pomoću šipki 11- Kutne poluge 7 i 8 se zakreću, a tračnica s jezičcem 3 se odmakne od glavne tračnice 1, pri čemu se tračnica s jezičcem 4 prislanja na glavnu tračnicu 2. To rezultira zrcalnom slikom jednakog položaja ustrojstva prikazanog na slici 2. Akumulator energije 14 stoji sada u drugom smjeru koso i kod prijelaza u ovaj novi položaj akumulator energije 14 prebacuje se iz prekretnog položaja u kojem on leži u jednoj liniji s krakovima 12 i 13, i stoga je stisnut na najmanju mjeru. U ovom premještenom položaju prislanja se tada krak 12 na graničnik 17, a krak 13 je odmaknut od graničnika 16. When moving the switch, the arms 9 and 10 of the angle levers are guided by rods 11- The angle levers 7 and 8 are rotated, and the rail with the tongue 3 moves away from the main rail 1, whereby the rail with the tongue 4 abuts on the main rail 2. That results in a mirror image of the same position of the arrangement shown in Figure 2. The energy accumulator 14 now stands in a different direction obliquely and when transitioning to this new position, the energy accumulator 14 is switched from the turning position in which it lies in one line with the arms 12 and 13, and therefore is squeezed to a minimum. In this moved position, the arm 12 then rests on the stop 17, and the arm 13 is moved away from the stop 16.

Budući da su krakovi 12 i 13 preko akumulatora energije 14 uvijek pritisnuti na jedan od graničnika 16 i 17 (kod položaja prikazanog u crtežu je krak 13 pritisnut. na graničnik 16), kutnim polugama 7 i 8 u zajedničkom djelovanju s akumulatorom energije 14 ograničava se također najuži prolaz 15 između glavne tračnice 2 i tračnice s jezičcem 4, a uz jamčenje najužeg prolaza uspijeva, da vijenci kotača mogu bez zapreke prelaziti glavne tračnice 1 i 2. Since the arms 12 and 13 are always pressed against one of the stops 16 and 17 via the energy accumulator 14 (in the position shown in the drawing, the arm 13 is pressed against the stop 16), the angular levers 7 and 8 in joint action with the energy accumulator 14 are limited also the narrowest passage 15 between the main rail 2 and the rail with the tongue 4, and with the guarantee of the narrowest passage succeeds, that the rims of the wheels can cross the main rails 1 and 2 without hindrance.

Kod premještanja skretnice protusmjerno se time pokreću krajevi odnosno mjesta zglobnih ležajeva 18 i 19 krakova 12 i 13 Time kut α, koji zatvara linija djelovanja 20 sile akumulatora energije 14 s krakovima 12 i 13, postaje bitno veći, nego kada bi akumulator energije 14 bio stacionarno poduprt, a krajnji se položaj kutnih poluga 7 i 8, koji određuje prolaz 15 između glavne tračnice i tračnice s jezičcem, održava s većom sigurnošću. 21 je teleskopska cijev, koja sprječava izvijanje tlačne opruge 14 koja formira akumulator energije. When the switch is moved in the opposite direction, the ends or places of the articulated bearings 18 and 19 of the arms 12 and 13 are moved in the opposite direction. Thus, the angle α, which is closed by the line of action 20 of the force of the energy accumulator 14 with the arms 12 and 13, becomes significantly larger than if the energy accumulator 14 were stationary supported, and the end position of the angle levers 7 and 8, which determines the passage 15 between the main rail and the tongue rail, is maintained with greater security. 21 is a telescopic tube, which prevents bending of the compression spring 14 which forms the energy accumulator.

Kod ustrojstva prema slici 3 opet je položaj tračnica s jezičcem 3 i 4 određen relativno prema glavnim tračnicama 1 i 2 kutnom polugom 7 i 8. Krakovi 9 i 10 se, preko šipki 22 kod 23 koje se mogu regulirati, hvataju na tračnice s jezičcem 3 i 4. Na krakove 12 i 13 se opet hvata akumulator energije 24. Ovi akumulatori energije 24 su ovdje međutim uprti prema ležaju 27 stacionarno pričvršćenom na pločama 25, koje su učvršćene na pragovima 27. In the arrangement according to Figure 3, the position of the rails with the tongue 3 and 4 is again determined relative to the main rails 1 and 2 by the angle lever 7 and 8. The arms 9 and 10 are attached to the rails with the tongue 3 via adjustable rods 22 and 23. and 4. On the arms 12 and 13 the energy accumulator 24 is again caught. These energy accumulators 24 are here, however, directed towards the bearing 27 stationary attached to the plates 25, which are fixed on the thresholds 27.

Obje tračnice s jezičcem mogu po potrebi biti međusobno povezane šipkom 30 koja se može regulirati po duljini. Kada se u ovom području uvijek u određenom slučaju jedna od tračnica s jezičcem 3 ili 4 prislanja na glavnu tračnicu 1 ili 2, mogu se graničnici 29 nadomjestiti spojnom šipkom 30. Kod izvedbenog primjera prema slici 3 ploče 25 s kutnim polugama 7 i 8 smještene su izvan kolosijeka s obje strane istog. Ove ploče 25 s kutnim polugama 7 i 8 mogu također biti smještene između kolosijeka. If necessary, both rails with a tongue can be connected to each other by a rod 30, which can be adjusted in length. When in this area, always in a certain case, one of the rails with a tongue 3 or 4 adjoins the main rail 1 or 2, the stops 29 can be replaced by a connecting rod 30. In the embodiment according to Figure 3, the plates 25 with corner levers 7 and 8 are placed off track on both sides of it. These plates 25 with angle levers 7 and 8 can also be placed between the rails.
