Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of large platform fixing equipment, and in particular relates to a locking device for a vehicle transfer platform. Background Technology
[0002] The transfer platform operates on tracks within its dedicated pit. Its main functions are to move locomotives, coke tank carriers, and quenching cars to designated maintenance locations, and to move these vehicles from their maintenance locations onto their corresponding tracks. The transfer platform is manually operated by personnel via buttons on a control panel located next to the pit. Currently, in practical use, due to users expanding production capacity and limited space, locomotives or coke tank carriers need to operate on the transfer platform for extended periods to improve efficiency. The frequent and continuous up-and-down movement of these vehicles impacts the platform, causing instability and affecting the safe operation of the locomotives, coke tank carriers, and quenching cars. Utility Model Content
[0003] The purpose of this invention is to provide a locking device for a car transfer platform, which solves the problem of instability caused by the impact of locomotives, coke tank transport cars, and coke quenching cars on the car transfer platform.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A locking device for a vehicle relocation platform includes an embedded plate, a base, a first stop block, a second stop block, and a third stop block. The embedded plate is fixed to a wall. The second stop block is welded to the embedded plate. The second stop block is a hexahedral structure with an inclined side, the inclined side being on the outer side. Both sides of the second stop block are bolted to the first stop block. The first stop block is a right-angled trapezoidal plate with its inclined side on the outer side, the angle of which is the same as the angle of the inclined side of the second stop block. An irregular groove is formed along the inner side of the inclined side of the first stop block from top to bottom, the groove not reaching the bottom. The groove consists of two surfaces, one of which forms a plane with the inclined side of the second stop block. The base includes a bottom plate, side plates, and a fixing plate. The base plate is vertically arranged and has bolt holes on both sides for fixing to the transfer platform. Side plates are fixed inside the bolt holes on the base plate, and the side plates are symmetrical to each other. Rails are provided inside the side plates. The bottom of the fixing plate is fixed to the base plate, and the two ends are fixed to the side plates. A screw is threaded to the center of the fixing plate, and a handwheel is fixed to the top of the screw. The bottom end passes through the third stop block, and the screw is fixed to the bottom and top of the third stop block by bolts. The third stop block is a hexahedral structure with an inclined surface. The inclined surface of the third stop block is opposite to the inclined surface of the second stop block. Guide rails are welded to both sides of the plane facing the inclined surface of the third stop block. The guide rails are connected to the rails inside the side plates. The inclined surface of the third stop block fits with the second stop block and the first stop block.
[0006] Preferably, a shim is added between the first stop block and the second stop block to adjust the gap between the first stop block and the second stop block, ensuring that the third stop block can be inserted smoothly.
[0007] Working principle: Pre-embedded plates are fixed at the four corners of the pre-stop position of the transfer platform. Second stop blocks are welded to the first stop blocks. The transfer platform is moved to the designated position via the local control box. It aligns its own anchoring with the ground foundation track. Bases are fixedly connected to the corresponding four corners of the transfer platform. Screws are threaded onto the fixing plates, and a handwheel is fixed at the top. A third stop block is installed, and the bolts at the top and bottom of the third stop block are tightened. Rotating the handwheel drives the screw to rotate, causing the third stop block to slide in the track on the side plate of the base until it contacts the first stop block. Using friction, the platform is self-locked and secured to the wall. The handwheels at the four corners are adjusted until they cannot be turned further, keeping the transfer platform stationary in both the traveling and perpendicular directions. Turnbuckles are used to connect the transfer platform to the ground foundation, securing it. The bottom bolt of the third stop block is loosened, and the handwheel is rotated to lower it below the transfer platform track, without affecting the operation of the locomotive, coke tanker, and quenching car.
[0008] The beneficial effects achieved by this utility model are as follows:
[0009] (1) The third stop block is moved up and down by adjusting the rail on the side plate of the base through the handwheel and screw, so that the third stop block is connected with the first stop block and the second stop block. The friction force is used to lock the self-locking, so that the matching of the transfer platform rail and the bottom guide rail of the electric locomotive is more accurate. This can eliminate the wear when the electric locomotive passes through the rail interface, and at the same time keep the transfer platform stationary in both the traveling direction and the vertical traveling direction. This avoids the problem of instability of the transfer platform caused by the impact of the electric locomotive, coke tank transport car and coke quenching car, and ensures the smooth operation of the electric locomotive, coke tank transport car and coke quenching car.
[0010] (2) The device is easy to assemble and disassemble, and has low cost. Attached Figure Description

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0019] like Figure 1-6 As shown, a locking device for a vehicle relocation platform includes an embedded plate 1, a base 2, a first stop block 3, a second stop block 4, and a third stop block 5. The embedded plate 1 is fixed to the wall. The second stop block 4 is welded to the embedded plate 1. The second stop block 2 is a hexahedral structure with an inclined surface, the inclined surface being on the outer side. Both sides of the second stop block 4 are bolted to the first stop block 1. The first stop block 3 is a right-angled trapezoidal plate, with the inclined side on the outer side, and the angle of the inclined side is the same as the angle of the inclined surface of the second stop block 4. Similarly, the first stop block 3 has an irregular groove formed from top to bottom along the inner side of the inclined side, and the groove does not reach the bottom. The groove consists of two surfaces, one of which forms a plane with the inclined surface of the second stop block 4. The base 2 includes a base plate 21, side plates 22, and a fixing plate 23. The base plate 21 is vertically set and has bolt holes on both sides, which are fixed to the transfer platform by bolts. The side plates 22 are fixed inside the bolt holes on the base plate 21. The side plates 22 are symmetrical to each other. The inner side of each side plate 22 is provided with a track. The bottom of the fixing plate 23 is connected to the base plate 21. Plate 21 is fixed, and both ends are fixed to side plates 22. A screw 6 is threadedly connected to the center of plate 21. A handwheel 7 is fixed to the top of screw 6, and the bottom end passes through the third stop block 5. Screw 6 is fixed to the bottom and top of the third stop block 5 by bolts 8. The third stop block 5 is a hexahedral structure with an inclined surface. The inclined surface of the third stop block 5 is opposite to the inclined surface of the second stop block 4. Guide rails 9 are welded to both sides of the plane facing the inclined surfaces of the third stop block 5. The guide rails 9 are connected to the rails on the inner side of the side plate 22. The inclined surface of stop block 5 fits with the second stop block 4 and the first stop block 1; the bottom and top of the third stop block are fixed to the screw by bolts. The guide rail of the third stop block is combined with the base rail to realize the up and down movement of the third stop block when the screw rotates. The self-locking by friction completes the fixation of the transfer platform; by removing the bottom bolt of the third stop block, the handwheel is rotated to lower the handwheel until it is below the transfer platform rail, preventing the handwheel from affecting the subsequent operation of the locomotive, coke tank transport car and coke quenching car.
