Definitions

  • the invention relates to a trolley, in particular for chain hoists, load suspension devices and / or trailing cables, which comprises a cross-section of the rail consisting of flange and web parts, with opposing running wheels and guide rollers which are rotatably mounted in side-mounted wheel carriers connected below the cross-section of the rail, with at least one the wheel carrier is provided with a load suspension device.
  • a trolley with a hoist with a short overall height which has running wheels running on the lower flange of a rail and mounted on a support frame.
  • One of the wheels of this lower flange trolley is driven and mounted on a rocker which is pivotally arranged on the support frame.
  • a friction wheel is arranged on the rocker arm, which rests on the lower flange of the rocker arm from below and is connected to the driven impeller in terms of drive.
  • An adjustable eccentric provided ensures that all impellers rest evenly on the lower flange.
  • This trolley proves to be advantageous for applications in which high frictional reinforcement is required; a disadvantage is the very high installation effort when mounting the trolley on the carrier.
  • these trolleys are not suitable for different web thicknesses and flange widths.
  • a trolley with at least one running wheel is known from DE 30 30 929 A1, which is provided with laterally arranged guide rollers for perfect guiding on the rail support, said guide rollers abutting one another on vertical guide surfaces of a rail support.
  • the upper guide rollers together with the lower guide rollers effectively prevent the trolley from tilting on the rail support and the front guide rollers together with the rear guide rollers ensure that the trolley is guided properly in the longitudinal direction of the rail support.
  • It is also a disadvantage of this trolley despite the small number of individual parts, that the assembly of the trolley on the carrier is relatively complex.
  • This trolley also has a small space of about 1 mm between the guide surfaces and the guide rollers to compensate for tolerances, which means that the parallel running of the rollers is not always guaranteed.
  • a very good parallel running of the rollers must be ensured in and outside of bends.
  • the running gear should run stably on the carrier rail even with a swinging load, so it should not tend to pitch movements and sideways swinging of the running gear.
  • the invention provides that wheel carrier arms which can be pivoted in or out in pairs are pivotably mounted about an axis extending in the direction of the rail and extending below the rail cross-section, the load on at least one of the wheel carrier arms at the level or below the joint formed in each case of the wheel carrier arms connected to one another attacks and the Wheel carrier arms are kept pivoted in on the cross-section of the running rail to a limited extent by a closing torque resulting from the load from the guide rollers resting on both sides of the web.
  • the undercarriage according to the invention makes it possible to hang it up in the preassembled state with a few hand movements on a travel rail with a corresponding travel rail cross section, the running gear comprising the travel rail cross section consisting of flange and web parts.
  • the (automatically) backlash-free guide rollers which rest on both sides of the web, ensure that the rollers run evenly in parallel, which in turn means that the rolling resistance and thus wear on the rollers are low; the guide rollers are also subject to very little wear in the solution according to the invention. Low wear is associated with low driving resistance, so that the undercarriage can be moved with relatively little effort.
  • the undercarriage pivoted in by the load proves to be very advantageous, especially when cornering, since the parallel running of the rollers is ensured even when cornering.
  • the constantly attached guide rollers ensure stable guidance of the undercarriage even when the load is swinging. Changes in diameter of the wheels and the guide rollers due to unavoidable abrasion is compensated for in the chassis according to the invention within a large tolerance range in that the chassis automatically adapts to the rail.
  • the wheel carrier arms are each designed as a frame pivotably mounted on the axle, each of which accommodates at least two opposing wheels in the center and pairs of horizontal guide rollers in front and behind the wheels, the wheels being located Support on the flange parts and press the horizontal guide roller pairs against the web of the rail cross section. If only two wheels are used, the result is particularly good maneuverability in curves.
  • the stability of the undercarriage is particularly great when the frame with the wheels and with the horizontal guide roller pairs is so far above the the respective flange part of the cross-section of the rails can be swiveled in so that the wheels run close to the web.
  • the frames are designed in such a way that there is a driving play between the flange part running surface of the rail cross section and the directly opposite surface of the frame. This can be, for example, one millimeter.
  • the driving game ensures that the load and the drive do not fall if the wheel breaks.
  • the chassis can then be used as a "suspension claw", for example when defective or worn wheels have to be replaced.
  • a favorable size with few components and low costs can be achieved if the joint formed below the cross-section of the rail is at the same time a suspension device for the load to be attached.
  • the adjustment of the undercarriage to different web thicknesses can advantageously also take place in that the angular position between the frames for the running wheels or for the guide rollers can be adjusted by means of adjustable spacing means.
  • a set screw can be used as a sling. In this embodiment, part of the closing force resulting from the load is absorbed within the chassis itself.
  • Two different angular positions of the frames for adaptation to different flange inclinations can be achieved very simply by providing two bores in the frame in the region of the joint, two different angular positions of the frames being adjustable by means of a pair of holes and a screw penetrating both frames. This makes it possible to cover all standard cases that occur with a cylindrical standard roll.
  • a compact and robust undercarriage with simple drive attachment results if an impeller is directly motor-driven with two impellers.
  • the drive can be carried out largely maintenance-free.
  • the running stability of the undercarriage is improved in that the wheel or wheels of one frame are offset from one another in the direction of travel relative to the wheel of the other frame.
  • the invention proposes that the guide rollers protrude from the frame in the direction of travel. This means that no additional plastic or rubber buffers are required.
  • Identical frames can be used for the right and left frames if the ends of the two frames that form the joint are fork-shaped and axially offset on the axis and if both ends of the frame are articulated with a central screw.
  • the chassis is also compact in that the load is supported on the screw connection by means of a suspension bracket.
  • the suspension bracket can be provided with a cross hole, so that the suspension of the load can be fastened rotated by 90 ° with little effort.
  • a connection, in particular secured against rotation, is achieved in that a hexagon socket recess is incorporated into the frame ends for a hexagon screw.
  • a very simple fixation results when the snap lock is formed by a spring-type locking element with bolts, the bolts protruding through a free hole in each frame and snapped into a recess in the opposite frame.
  • a very even load distribution is achieved if the load acts on at least one of the frames in the center of the cross-section of the running rail.
  • a chassis is shown in front view, which comprises a rail 1, which consists of flange parts 2 and a web 3.
  • the undercarriage itself has two wheel carrier arms 4a, 4b, which are designed as frames 5a, 5b.
  • the frames 5a, 5b are mounted so as to be pivotable about an axis 6 which extends in the direction of the running rail 1 and runs below the cross-section of the running rail, which enables the frames 5a, 5b to be pivoted open or closed.
  • Fig. 1 shows that in the upper region of the frame 5a, 5b a pair of opposing wheels 7 are arranged, the axes of rotation of which are horizontal and are supported in the frame 5a, 5b.
  • the frames 5a, 5b take in addition to the centrally arranged in the frame 5a, 5b wheels 7 in front and behind the wheels 7 arranged horizontal guide roller pairs, which consist of guide rollers 9, which are supported in the frame 5a, 5b in a vertically rotatably mounted manner. While the running wheels 7 are supported on the lower flange parts 2, the guide rollers 9 rest in pairs on the web 3 of the running rail 1. 1 shows that the frames 5a, 5b can be pivoted so far over the respective flange part 2 of the rail cross section of the rail 1 that the running wheels 7 move directly near the web of the web 3.
  • the load on the load hook 11 engages the axis 6; the joint formed below the running rail 1 is at the same time a suspension means for the load to be suspended.
  • a suspension means for the load to be suspended are also conceivable, but it is crucial that the load acts on the height or below the joint 10 of the frames 5a, 5b interconnected by the joint on at least one of the frames 5a or 5b in the center of the cross-section of the rail.
  • FIG. 2 shows a partially sectioned plan view of the undercarriage according to FIG. 1 (the travel rail is omitted in FIG. 2).
  • FIG. 3 shows a front view of the undercarriage according to FIG. 1, in which the angular position between the frames 5a, 5b for the running wheels 7 and for the guide rollers 9 can be penetrated by means of an adjustable spacing means 12.
  • the spacer 12 shown in FIG. 3 is a stop 13 with an adjusting screw. In addition to the adjustment of the angular position between the frames 5a, 5b, the stop 13 causes the closing torque resulting from the load to be absorbed essentially within the chassis itself.
  • a driving game 15 is present between the flange part tread 8 of the travel rail 1 and the surface 14 directly opposite this.
  • the driving play 15 is approximately 1 mm and prevents the undercarriage from falling in the event of a wheel break, in particular thereby preventing shear from falling.
  • the driving game 15 also makes it possible to use the undercarriage as a suspension claw, which enables the wheels to be replaced easily, for example by means of a support plate inserted into the gap in the driving game 15.
  • the frames 5a, 5b are provided in the region of the joint 10 with two bores 16, 16a parallel to the axis 6 (Fig. 1 and Fig. 3a), which enables a second angular position of the frames 5a, 5b by displacing the axis 6, so that the running gear can be optimally adjusted for a second flange inclination.
  • Fig. 3a a chassis is shown, in which the axle 6 is inserted into the second bore 16, which - as can be clearly seen in Fig. 3a - allows an optimal adaptation to the inclined flange inclination of the rail 1 in Fig. 3a.
  • impeller 7 of a frame 5a or 5b offset relative to the impeller 7 of the other frame 5b or 5a in the direction of travel. This measure can also be used to increase the positional stability during load transport.
  • Fig. 2 also shows that the guide rollers 7 protrude from the frame 5a, 5b in the direction of travel and form a buffer to an end stop (not shown), whereby no rubber or plastic buffers are additionally required.
  • the two fork-shaped (see FIGS. 1 and 3) frames 5a, 5b are of identical design and are arranged with their ends axially offset on the axis 6.
  • a hexagonal recess 17 is worked into the frame ends of the frame 5a, 5b articulated to one another with a central screw connection by means of a screw 6a designed as a hexagon screw.
  • the load is supported on the screw 6a via a suspension bracket.
  • a snap lock 19 can be seen as a safeguard against inadvertent opening of the undercarriage when relieved, which latches automatically when closed, but can only be released by hand when opened.
  • the snap lock 19 is formed by a resilient locking element 20 and a bolt 21.
  • the bolt 21 protrudes - penetrating a bore 22 of the outer frame 5a - in the operating position into a recess 23 of the inner frame 5b and is held in this.
  • the ratio of the vertical distance between the axes of the impellers 7 'and the horizontal distance of the impellers 7 from the axis 6 (swivel axis) is greater than 3 and less than 10.
