Definitions

  • Elevators of this type are increasingly required for reasons of safety and sensible design, as well as to speed up the workflow in construction, repairs and renovations. On the one hand, they serve to erect the scaffolding, on the other hand to dismantle the scaffolding, but above all to transport materials during work on the structure.
  • Known lifts with racks either have a rack and a trolley with a permanently attached load holder, on which a load cage is usually already attached, or there are two independent racks on two racks, each with a fixed load holder and / or basket.
  • Other lifts work with ropes as single or double lifts.
  • Various facilities are also known for using height-adjustable work platforms on buildings. These have support and lifting devices located at a distance from one another at the ends of the respective stage section.
  • the invention is based on the knowledge that the longest time is used for loading or unloading a load basket.
  • the invention has for its object to provide an elevator with a column on which two load holders can be used in many ways, especially in such a way that a load holder at the lower end and another load holder can be used at any higher level, but that for two load holders or the elements assigned to them, such as load baskets or work platforms, only one drive with the associated components and auxiliary elements is required.
  • load baskets with secure entry doors or the like are expediently provided, which are assigned to the load holders and are generally firmly attached to them for longer use. Then you can use the load holders like ordinary elevator baskets. However, you can also assign working platforms to the load holders and, above all, set up lifts in pairs and between two Provide columns with a longer working platform with the assigned safety aids. For example, a company that needs several of the same lifts for a smooth workflow can occasionally use them for work with larger work platforms.
  • the elevator 50 has a base frame 51 with a vertical column 52 on which a carriage 53 with drive can be moved vertically.
  • Load carriers 55.1 and 55.2 can be coupled laterally to the carriage 53.
  • Load baskets 56.1 and 56.2 are on these.
  • the load baskets 56 .. have a width 57 which, because of the transport on the road, should as a rule not be greater than the distance between the outer surfaces of the running wheels.
  • the base frame 51 has a rigid axle 58 with spring-loaded wheel carriers 59, to which rubber-tired wheels 60.1 and 60.2 are attached on both sides of the base frame 51 in the usual manner of vehicle trailers. These wheels 60 are provided in the longitudinal center of the base frame 51 on both sides of the column 52.
  • the base frame 51 is formed like a rectangular frame, as shown above all in FIGS. 7 and 9.
  • Longitudinal beams 61.1 and 61.2 are connected by internal cross struts 62.1 and 62.2 near the axis 58 and have 63 cross struts 64.1 and 64.2 in the region of their ends.
  • customary height-adjustable support feet 65.1 to 65.4 are provided, by means of which the entire elevator 50 is supported on the floor and its column 52 can be aligned vertically.
  • the impellers 60 .. or at least their springs are then relieved. Similar arrangements are common in such portable elevators, but here the design of the base frame is such that it is suitable for supporting the optional and jointly usable two load holders 55 ..
  • a base plate 66 is provided on the base frame 51, which is supported on the longitudinal members 61.1 and 61.2 and the inner cross struts 62.1 and 62.2 and is fastened to cover the space, for example welded on.
  • the carriage 53 is - as can be seen particularly well from the basic structure shown in FIG. 7 without drive parts - as a box frame 70 which is open on one side and has four vertical bars 71.1, 71.2, 71.3, 71.4. These are connected in the side areas by horizontal struts 72.1 to 72.4 and on the front side in the drawings by a lower horizontal strut 73 and two connecting and support plates 74.1 and 74.2. A coupling carrier 75.1 to 75.4 is formed at each corner at the top.
  • the two load holders 55.1 and 55.2 are assigned to the carriage 53.
  • the load holders 55 .. are designed as angle elements and each have two vertical arms 76.1 to 76.4 which carry coupling eyes 78.1 to 78.4 projecting at their upper ends 77.1 to 77.4 in the direction of the column 52. They have a length 79, which corresponds approximately to the height 80 of the carriage 53.
  • the load holders 55 .. each have two horizontal longitudinal arms 81.1 to 81.4, which are connected at their outer ends by cross bars 82.1 and 82.2 and at the ends facing the column 52 to the vertical arms 76.1 to 76.4 and in each case by an inner cross strut 83.1 and 83.2 .
  • the outer fitting surfaces 84.1 of the vertical rods 71 are at a distance 85 which is matched to the dimensions of the column 52, taking into account the support of tilting forces.
  • the inner mating surfaces 86 of the vertical arms 76 .. of the load holder 55 .. have a distance 87 which is greater by a play than the distance 85, so that the carriage 53 freely move out of the load holder 55 .. in the disengaged state and back into this can drive in.
  • two insertion tabs 91.1 to 91.8 are attached to the cross struts 64 and 62 of the base frame 51 for centering the load holders 55. These have vertical fastening areas 92 and in each case meaningfully bent insertion areas 93, each of which forms an insertion bevel 90 above the mounting surfaces 84 of the longitudinal beams 61 .. and cross struts 62 .. and 64 .. - as shown in particular in FIG. 7. As illustrated by the spatial assignment of the oblique exploded view in FIG.
  • the lowering load supports 55 with the lower edges 95 of the inner surfaces of their horizontal longitudinal arms 81 .
  • the appropriate longitudinal alignment is done by the given coupling to the carriage 53 and the carriage 53 to the column 52, as will be described below.
  • Help with this can be arranged on the base plate 66, vertical positioning bolts 96.1 and 96.2, which enter into positioning holes 97.1 and 97.2, which are arranged centrally in the horizontal inner cross struts 83.1 and 83.2 of the load holder 55 ..
  • insertion bevels 98.1 to 98.4 are formed on the vertical bars 71. These are assigned to the oblique insertion surfaces 99.1 to 99.4 on carriage insertion lugs 100.1 to 100.4, which are attached to inwardly projecting ends 101 of the horizontal longitudinal arms 81.1 to 81.4 and which likewise have insertion regions 102.1 to 102.4 which are bent outwards at the top.
  • insertion tabs 103.1 to 103.4 are fastened to the inner cross struts 83.1 and 83.2, the upper insertion slopes 104 of which are bent outwards at the top.
  • the lower edges 105 of the horizontal struts 72 are assigned to the oblique insertion surfaces 99.1 to 99.4 on carriage insertion lugs 100.1 to 100.4, which are attached to inwardly projecting ends 101 of the horizontal longitudinal arms 81.1 to 81.4 and which likewise have insertion regions 102.1 to 102.4 which are bent outwards at the top.
  • insertion tabs 103.1 to 103.4 are fastened to the inner cross stru
  • a geared motor 110 is attached to the upper connecting and support plate 74.2, which allows different speeds to be switched on and one Drive pinion 111 carries on its output shaft projecting through the upper pinion opening 121.
  • This drive pinion 111 engages in a rack 112 and serves the upward and downward movements, as is customary in such elevators with racks.
  • a single rack running vertically from bottom to top is provided, which is subdivided according to the subdivision of the column elements.
  • a safety and braking device 125 is attached to the lower connecting and support plate 74.1.
  • the safety pinion 126 is arranged on a shaft 127 which extends through the safety opening 128.
  • Other auxiliary devices are designed in the usual way.
  • the energy supply and control signal transmissions take place via a cable, not shown, which is automatically deposited in a cylindrical cable container 120 in the usual manner when moving down and which is dimensioned in terms of its length in accordance with the lift height of the elevator.
  • the carriage 53 has roller carriers 115. These carry rollers 116.1 to 116.16 on suitable, eccentrically mounted and adjustable axes, the running surfaces 117 of which are in support in a generally known manner on the guide surfaces 118 of the guide rails 135 of the column 52.
  • the column profile - as can be seen from FIGS. 8 and in particular FIGS. 9 and 10 - is designed as a light metal extruded profile 130. It has inner support struts 131 and a C-profile 132 on the free side. Holding elements 133 are inserted into this. With their help, holding arms 134 are attached to the frame 137 and / or to the structure 138.
  • the profile 130 has an elongated rectangular shape with two oppositely formed guide rails 135, which together with the side walls 136 limit the guide surfaces 118 .. for the rollers 116 .. in the manner shown in FIGS. 9 and 10.
  • Four rollers 116 .. are arranged in the respective height on parallel axes and two additional rollers 116 .. on each side on axes offset by 90 °.
  • Such roller sets of eight rollers 116 .. are provided at the lower and upper ends of the carriage 53. Due to the large spacing of the rollers 116 .. and the solid design of the guide rails 135, all forces arising from the considerable loads of the large load baskets 56 .. and the bulky parts to be transported therein can be well absorbed and derived.
  • the carriage 53 has coupling devices 160 of the same design and assigned to the coupling carriers 75.1 to 75.4 on each side. These have coupling pins 161.1 and 161.2 in round bores 162.1 and 162.2 in the carriage-side coupling supports 75.1 to 75.2 shown only from the left side in FIGS. 13 and 14, which are piston-like and preferably designed with an anti-rotation device. They are associated with connecting rods 163.1 and 163.2, which are articulated diagonally opposite one another on a common crank disk 164 by means of crank pins 165.1 and 165.2. An actuating lever 166 is assigned to the crank disk 164 and has a rotary bearing 167 at its upper end.
  • a hand lever 168 engages this, which permits the actuation lever 166 to be pivoted by approximately 90 °, as shown in FIGS. 13 and 14.
  • the crank disk 164 can assume two end positions. In the one end position shown in FIG. 14, the connecting rods 163.1 and 163.2 are stretched and the coupling pins 161.1 and 161.2 are extended. In the other position - see FIG. 13 - the coupling pins 161.1 and 161.2 are completely retracted and the load holder 55 is thus uncoupled from the carriage 53.
  • a spring arrangement 170 engages with a tension spring 171, which ensures that the actuating lever 166, when it has exceeded the middle dead center position by a small amount, automatically into the respective end position is moved to ensure that the clutch is either switched on in the clutch position or switched off in the release.
  • elongated holes 180 are provided, into which the coupling pins 161.1 and 161.2 - as can be seen from FIG. 14 - can enter.
  • the elongated holes 180 have securing slopes 181 in their upper end regions. 15 and 16 - the arrangement is such that in coordination with the angular position and the installation position of the spring arrangement 170 when the spring remains in an intermediate position, either the spring is effective to move the arrangement into an end position or when lifting the car, the safety bevels 181 and 183 come against each other and the secured and fully loadable end position is assumed by the resulting horizontal displacement.
  • both load holders 55.1 and 55.2 are coupled to the carriage 53 and, together with their load baskets 56.1 and 56.2, are brought into a raised position according to the conditions of use, in which they are both at the top.
  • FIG. 5 Such a type of use - but to a lesser extent - corresponds to FIG. 5, in which a scaffold 137 is shown on a building wall 138.
  • the elevator 50 stands outside the scaffolding. Its column 52 is anchored to the scaffolding 137 with two holding arms 134. Further information follows from the above explanations.
  • Fig. 3 shows a form of use in which the right load holder 55.2 is uncoupled from the carriage 53, while the left load holder 55.1 is coupled to the carriage 53 and lifted together with it, so that, for example, unloading can be carried out at the top while simultaneously loading at the bottom .
  • Fig. 4 shows an inverted arrangement in which the load holder 55.2 is now raised with its load cage 56.2 and is now unloaded, while the load holder 55.1 now rests with its load cage 56.1 on the base frame 51 and is decoupled from the carriage 53, so that it can be reloaded below.
  • the load baskets can be loaded and unloaded alternately and only need to be coupled and lifted or lowered with the trolley 53.
  • FIG. 6 Another type of use is shown in FIG. 6.
  • elevators 50.1 and 50.2 are set up at a distance from one another.
  • the external load holders 55 are each equipped with small, basket-like working platforms 187. Both load holders 55 are coupled to each carriage 53.
  • a longer working platform 188 which corresponds to the distance between the two elevators 50.1 and 50.2, is supported on the load holders 55.3 and 55.4 facing one another by means of suitable fastening. It is equipped with additional security devices, grilles and the like but are not shown here due to their general popularity.
  • both elevators are equipped with suitable auxiliary devices to achieve synchronism, so that the work platform 188 is raised and lowered horizontally and there is no risk of an accident.
  • Such an arrangement intended for the use of people at greater heights must be equipped with the appropriate safety devices.
  • the advantageous new elevator construction can also be used sensibly here.
  • the elevator has a base frame (51) with a vertical column (52) which is divided into sections and each has a rack (112) composed of sections.
  • a vertical column (52) which is divided into sections and each has a rack (112) composed of sections.
  • an up and down movable carriage (53) is provided, which has suitable drive and safety devices which reach through the openings (121, 128).
  • Load carriers (55.1, 55.2) are assigned to the carriage (53), which can be coupled individually or together with the carriage (53). Appropriate auxiliary and centering devices ensure the perfect function for loading the load holder on one side, while the load holder on the other side can assume a different height or be moved.
