Description

Technical Field

[0001] This utility model belongs to the technical field of track slab paving trolleys, and particularly relates to a track slab paving trolley with an adjustable angle for gripping inclined track slabs. Background Technology

[0002] like Figure 5 , 6 As shown in Figure 7, 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 track slabs 700 are neatly stacked. The top support 200 moves laterally and the traveling support 100 moves longitudinally, moving the movable grippers 600 directly above the track slabs 700. The four drive mechanisms 500 drive the four columns 400 to move up and down, positioning the four movable grippers 600 at the four corners of the track slabs 700. The four movable grippers 600 clamp the four corners of the track slabs 700. The four drive mechanisms 500 then drive the four columns 400 to lift the four movable grippers 600 and the track slabs 700. The top support 200 moves laterally and the traveling support 100 moves longitudinally, moving the track slabs 700 to any position on the railway track. Finally, the track slabs 700 are lowered and released to complete the track slab installation.

[0003] However, when gripping the track slab, the movable claw 600 can only move laterally via the top support 200 or longitudinally via the traveling support 100. If the construction workers do not place the track slab 700 neatly, the movable claw 600 will be unable to grip the track slab 700. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a structure for adjusting the angle of the inclined track slab gripping of a track slab laying trolley.

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

[0006] An adjustable structure for the angled gripping of a track slab paving trolley includes a top support, which comprises an upper support, a rotating support, and a sliding support. The upper support has upper mounting holes at its four corners for mounting sliding sleeves, and the sliding support has lower mounting holes at its bottom for sliding connection with a traveling support. The upper support is fixedly connected to the top of the rotating support, and the rotating support is connected to the top of the sliding support. The center of the rotating support is hinged to the center of the sliding support. A telescopic hydraulic cylinder connects the rotating support and the sliding support. When the telescopic hydraulic cylinder extends or retracts, it drives the rotating support to rotate relative to the sliding support on a horizontal plane with the hinge point as the center.

[0007] Preferably, the rotating bracket is provided with an upper hinge seat, the sliding bracket is provided with a lower hinge seat, and the two ends of the telescopic cylinder are respectively hinged to the upper hinge seat and the lower hinge seat.

[0008] Preferably, the sliding bracket has a vertically upward rotating shaft at its top center, and the rotating bracket has a vertically penetrating bushing at its center, with the bushing fitted onto the rotating shaft.

[0009] Preferably, a bearing is connected between the bushing and the rotating shaft.

[0010] Preferably, a bracket is provided above the bushing, and an encoder is provided on the bracket. The central shaft of the encoder is connected to the top of the rotating shaft via a coupling.

[0011] Preferably, the top of the sliding bracket is provided with a smooth panel, and the bottom of the rotating bracket is provided with a wear-resistant plate, the wear-resistant plate being fitted and connected to the smooth panel.

[0012] The beneficial effects of this utility model are:

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] This invention uses a telescopic hydraulic cylinder to drive a rotating bracket to rotate relative to a sliding bracket on a horizontal plane around the hinge point between the two. This rotation drives the upper bracket and components connected to the upper bracket, such as the sliding sleeve, column, drive mechanism, and movable claw, to rotate, aligning the movable claw with the track plate. This facilitates the movable claw in gripping the inclined track plate, solving the problem that the movable claw cannot grip the track plate when the construction workers have not placed it neatly.

[0022] 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.

[0023] like Figure 1-4 As shown, this utility model provides a technical solution: an adjustable structure for the gripping angle of an inclined track slab of a track slab paving trolley, including a top support 200. The top support 200 includes an upper support 201, a rotating support 202, and a sliding support 203. The upper support 201 has upper mounting holes 301 at its four corners for mounting sliding sleeves 300. The sliding support 203 has lower mounting holes 101 at its bottom for sliding connection with a traveling support 100. The upper support 201 is fixedly connected to the top of the rotating support 202. The rotating support 202 is connected to the top of the sliding support 203. The center of the rotating support 202 is hinged to the center of the sliding support 203. A telescopic cylinder 1 is connected between the rotating support 202 and the sliding support 203. When the telescopic cylinder 1 extends or retracts, it drives the rotating support 202 to rotate relative to the sliding support 203 on a horizontal plane with the hinge point as the center.

[0024] When the track plate 700 to be gripped is placed at an angle during operation, the rotating bracket 202 can be pushed by the telescopic cylinder 1 to rotate relative to the sliding bracket 203 on the horizontal plane with the hinge point of the two as the center. This will drive the upper bracket 201 and the sliding sleeve 300, column 400, drive mechanism 500, movable claw 600 and other components connected to the upper bracket 201 to rotate, so that the movable claw 600 is aligned with the track plate 700. This makes it easier for the movable claw 600 to grip the inclined track plate 700, solving the problem that the movable claw 600 cannot grip the track plate 700 when the construction personnel have not placed it neatly.

[0025] Specifically, the rotating bracket 202 is provided with an upper hinge seat 21, and the sliding bracket 203 is provided with a lower hinge seat 22. The two ends of the telescopic cylinder 1 are respectively hinged to the upper hinge seat 21 and the lower hinge seat 22, thereby realizing the connection of the telescopic cylinder 1 between the rotating bracket 202 and the sliding bracket 203.

[0026] Specifically, the sliding bracket 203 has a vertically upward rotating shaft 31 at its top center, and the rotating bracket 202 has a vertically penetrating bushing 32 at its center. The bushing 32 is fitted onto the rotating shaft 31, thereby achieving a hinge connection between the center of the rotating bracket 202 and the center of the sliding bracket 203.

[0027] Furthermore, a bearing 33 is connected between the bushing 32 and the rotating shaft 31 to reduce friction and facilitate relative rotation between the rotating bracket 202 and the sliding bracket 203.

[0028] Furthermore, a bracket 41 is provided above the bushing 32, and an encoder 42 is provided on the bracket 41. The central shaft of the encoder 42 is connected to the top of the rotating shaft 31 through a coupling 43, so that the rotation angle of the rotating bracket 202 can be converted into an electrical signal and transmitted to an external CNC device, programmable logic controller (PLC), control system, etc., to realize the control of the rotation angle of the rotating bracket 202.

[0029] Furthermore, the top of the sliding bracket 203 is provided with a smooth panel 51, and the bottom of the rotating bracket 202 is provided with a wear-resistant plate 52. The wear-resistant plate 52 is in close contact with the smooth panel 51, which reduces the friction between the sliding bracket 203 and the rotating bracket 202 and can prevent wear between them.

[0030] 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.
