Description

Technical Field

[0001] This utility model belongs to the technical field of track slab paving trolleys, and particularly relates to a lifting compensation structure for the gripping plate structure of a track slab paving trolley. Background Technology

[0002] like Figure 4 , 5 As shown, an existing track slab paving trolley includes a traveling support 100 that spans across the railway track and can move along the direction of the railway track. A top support 200 is slidably connected to the top of the traveling support 100 and can slide laterally along the top of the traveling support 100 above the railway track. Four sliding sleeves 300 are connected to the four corners of the top support 200. A column 400 that can move up and down along the inner wall of each sliding sleeve 300 is connected inside each sliding sleeve 300 and the column 400. A drive mechanism 500 that drives the column 400 to move up and down is connected to each sliding sleeve 300 and the column 400. A movable claw 600 is provided at the bottom of each column 400. During operation, the four drive mechanisms 500 drive the four columns 400 to move up and down, so that the four movable jaws 600 are positioned at the four corners of the track slab 700. The four movable jaws 600 clamp the four corners of the track slab 700. Then, the four drive mechanisms 500 drive the four columns 400 to lift the four movable jaws 600 and the track slab 700. The track slab 700 is moved to any position on the railway track by the horizontal movement of the top support 200 and the longitudinal movement of the traveling support 100. Finally, the track slab 700 is lowered and released to complete the installation of the track slab.

[0003] However, since the track plate 700 is a rigid structure, the drive mechanism 500 needs to remain synchronized during operation so that the height and lifting speed of the two movable jaws 600 on the same side are consistent. Otherwise, if any one of the four clamping points at the four corners of the track plate 700 is not on the plane formed by the other three points, the track plate 700 will be damaged or deformed, which places high precision requirements on the drive mechanism 500. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a lifting compensation structure for the track slab paving trolley grab plate structure.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A lifting compensation structure for a track slab paving trolley gripper includes a column and a movable jaw. The column is located directly above the movable jaw. From top to bottom, an upper connecting plate, a rubber damping block, and a lower connecting plate are arranged between the column and the movable jaw. The rubber damping block is connected between the upper and lower connecting plates. The upper connecting plate has downwardly extending movable jaw connecting plates on its left and right sides, and the lower connecting plate has upwardly extending column connecting plates on its front and rear sides. The lower ends of the two movable jaw connecting plates are connected to the top sides of the movable jaw, and the upper ends of the two column connecting plates are connected to the bottom sides of the column. The rubber damping block deforms when compressed.

[0007] Preferably, the rubber shock absorber is provided with a top plate and a bottom plate on its upper and lower sides, respectively. The top plate and the bottom plate are integrally formed with the rubber shock absorber. The top plate is fixedly connected to the bottom of the upper connecting plate by bolts, and the bottom plate is fixedly connected to the top of the lower connecting plate by bolts.

[0008] Preferably, both the top plate and the bottom plate are made of rubber with dispersed metal wires inside.

[0009] Preferably, the maximum deformation of the rubber shock absorber in the height direction is 5mm-10mm.

[0010] The beneficial effects of this utility model are:

[0011] Compared with existing technologies, the advantages of this utility model are:

[0012] This invention connects the lower connecting plate to the bottom of the column via a column connecting plate, which supports the rubber shock absorber. The upper connecting plate connects to the top of the movable jaw via a movable jaw connecting plate, which in turn connects to the top of the rubber shock absorber. The rubber shock absorber can deform under pressure, providing space for the movable jaw to move downwards. Meanwhile, the other movable jaws rise relative to the movable jaw to compensate for the lifting and lowering of the movable jaws, ensuring that all movable jaws maintain a consistent height. This prevents the track plate from being damaged or deformed due to excessive force on the movable jaws at higher points. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a lifting compensation structure for a track slab paving trolley gripper structure, including a column 400 and a movable claw 600. The column 400 is located directly above the movable claw 600. From top to bottom, an upper connecting plate 1, a rubber shock absorber 2, and a lower connecting plate 3 are arranged between the column 400 and the movable claw 600. The rubber shock absorber 2 is connected between the upper connecting plate 1 and the lower connecting plate 3. Movable claw connecting plates 4 extending downward are respectively arranged on the left and right sides of the upper connecting plate 1. Column connecting plates 5 extending upward are respectively arranged on the front and rear sides of the lower connecting plate 3. The lower ends of the two movable claw connecting plates 4 are connected to the top sides of the movable claw 600, and the upper ends of the two column connecting plates 5 are connected to the bottom sides of the column 400. The rubber shock absorber 2 deforms when compressed.

[0020] like Figure 1 As shown, the four movable jaws 600 of the track slab laying trolley are all connected by a lifting compensation structure. During operation, the four movable jaws 600 clamp the four corners of the track slab 700 respectively. The four drive mechanisms 500 drive the four columns 400 respectively to lift or lower the four movable jaws 600 and the track slab 700. If the speed of some drive mechanisms 500 is inconsistent with that of other drive mechanisms 500, resulting in some movable jaws 600 being higher than other movable jaws 600, the track slab 700, due to its own weight and rigidity, will cause the movable jaws 600 at the higher point to move down to maintain the same height as other movable jaws 600, thus avoiding damage or deformation of the track slab 700.

[0021] Specifically, this utility model connects the lower connecting plate 3 to the bottom of the column 400 via the column connecting plate 5. The lower connecting plate 3 supports the rubber shock absorber 2. The upper connecting plate 1 is connected to the top of the movable jaw 600 via the movable jaw connecting plate 4. The upper connecting plate 1 is connected to the top of the rubber shock absorber 2. The rubber shock absorber 2 can deform under pressure, providing space for the movable jaw 600 to move downward. The other movable jaws 600 rise relative to the movable jaw 600 to compensate for the lifting and lowering of the movable jaws 600, so that all the movable jaws 600 keep the height consistent, and avoid the track plate 700 being damaged or deformed due to excessive force on the movable jaws 600 at higher points.

[0022] Furthermore, the rubber damping block 2 is provided with a top plate 6 and a bottom plate 7 on its upper and lower sides, respectively. The top plate 6 and the bottom plate 7 are integrally formed with the rubber damping block 2. The top plate 6 is fixedly connected to the bottom of the upper connecting plate 1 by bolts, and the bottom plate 7 is fixedly connected to the top of the lower connecting plate 3 by bolts, so that the rubber damping block 2 is stably connected to the upper connecting plate 1 and the lower connecting plate 3 respectively.

[0023] Furthermore, both the top plate 6 and the bottom plate 7 are made of rubber with dispersed metal wires, which not only ensures the hardness of the top plate 6 and the bottom plate 7, making them firmly connected to the upper connecting plate 1 and the lower connecting plate 3 respectively, but also facilitates the integral molding of the top plate 6 and the bottom plate 7 with the rubber shock absorber 2.

[0024] Furthermore, the maximum deformation of the rubber damping block 2 in the height direction is 5mm-10mm.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
