[0024] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the utility model. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or alternative embodiment excluding other embodiments.

[0025] EMBODIMENT

[0026] Referring to Figures 1-5 For the embodiment of the utility model, the embodiment provides a power plant car migration platform anti-slip device, which comprises,

[0027] The car migration platform body 100 comprises a car migration track 101, blocking blocks 102 arranged on both sides of the car migration track 101 respectively, a transmission rod 103 arranged on the inner side of the car migration track 101 and matched with the blocking blocks 102, and a through slot 104 opened on the outer surface of the car migration track 101 and matched with the blocking blocks 102;

[0028] It should be explained that the migration track 101 is used to provide a running path for the vehicle, and is a carrier for the vehicle to move on the migration platform. The blocking block 102 is used to block the vehicle. When the blocking block 102 is rotated and lifted, the vehicle can be physically blocked to prevent the vehicle from rushing out of the migration platform. When the transmission rod 103 rotates, the blocking block 102 on both sides can be stopped. The through slot 104 is used to provide a rotating space for the blocking block 102, so that the blocking block 102 can be stored below the outer surface of the migration track 101 when not in use, without affecting the normal passage of the vehicle.

[0029] The auxiliary mechanism 200 includes a driving assembly 201 for controlling the blocking block 102 to drive the transmission rod 103 to rotate, and a disassembly assembly 202 for connecting the blocking block 102 and the transmission rod 103.

[0030] Specifically, the driving assembly 201 includes an electric push rod 201a adapted to be installed on the inner side of the migration track 101, and a driving column 201b fixedly connected to the output end of the electric push rod 201a.

[0031] Further, the driving assembly 201 further includes a swing rod 201c fixedly connected to the outer surface of the blocking block 102, and a positioning groove 201d penetrating through the outer surface of the swing rod 201c and cooperating with the driving column 201b.

[0032] It should be noted that the electric push rod 201a is used to push the driving column 201b to move axially, and then the driving column 201b cooperates with the positioning groove 201d to push the swing rod 201c to rotate, so that the swing rod 201c drives the transmission rod 103 to rotate synchronously, and then the transmission rod 103 cooperates with the disassembly assembly 202 to drive the blocking block 102 to rotate.

[0033] Preferably, bearings are installed at the connection between the transmission rod 103 and the migration track 101 to cooperate with rotation, and the outer surface of the driving column 201b is in sliding contact with the inner wall of the positioning groove 201d.

[0034] It should be explained that the disassembly assembly 202 includes fixed sleeves 202a fixedly connected to both ends of the transmission rod 103, respectively, limiting grooves 202b respectively formed in the inner walls of the fixed sleeves 202a, springs 202c fixedly installed on the inner walls of the limiting grooves 202b, and inclined angle blocks 202d fixedly connected to the other ends of the springs 202c.

[0035] Further, the disassembly assembly 202 further includes a fixed column 202e fixedly connected to the outer surface of the blocking block 102 and cooperating with the fixed sleeve 202a, a connecting rod 202f fixedly connected to the other end of the fixed column 202e, a fixed block 202g fixedly installed on the other end of the connecting rod 202f, and a movable block 202h slidably sleeved on the outer surface of the connecting rod 202f.

[0036] It should be noted that the limiting groove 202b is used to provide a limiting space for the movement of the bevel block 202d, the spring 202c is used to provide a spring force for the bevel block 202d, so that it remains in the extended state when not subjected to external force, the bevel block 202d is used to limit the fixed block 202g, so that the fixed column 202e is firmly connected with the fixed sleeve 202a, so as to realize the effect of connecting the blocking block 102 and the transmission rod 103.

[0037] Specifically, the outer surface of the bevel block 202d is in sliding contact with the inner wall of the limiting groove 202b, and the fixed block 202g is the same shape as the movable block 202h and is opposite in direction.

[0038] In use, the vehicle runs smoothly on the vehicle migration track 101, the blocking block 102 is quietly stored in the through groove 104 and does not interfere with the vehicle, the output end of the electric push rod 201a and the driving column 201b are in the initial position of the positioning groove 201d, the swing rod 201c and the transmission rod 103 are stationary, the bevel block 202d is extended under the action of the spring 202c, and the fixed column 202e and the fixed sleeve 202a are firmly connected, so as to ensure that the blocking block 102 and the transmission rod 103 are firmly connected.

[0039] When the risk of coasting is monitored: control the electric push rod 201a to quickly push the driving column 201b to move, push the swing rod 201c to rotate through the cooperation of the driving column 201b and the positioning groove 201d, and then drive the transmission rod 103 to rotate synchronously, the transmission rod 103 drives the two blocking blocks 102 on both sides to rotate around the connection point through the disassembly assembly 202, and the blocking blocks 102 extend from the through groove 104 to block the coasting vehicle.

[0040] After the coasting risk is eliminated: control the electric push rod 201a to drive the driving column 201b to move reversely, drive the swing rod 201c and the transmission rod 103 to rotate reversely through the driving column 201b, so that the blocking block 102 rotates reversely and descends, and returns to the position parallel to the migration track 101 in the through groove 104, so as to ensure that the vehicle can continue to pass normally.

[0041] When the blocking block 102 needs to be maintained or replaced: push the fixed column 202e into the inside of the fixed sleeve 202a, drive the movable block 202h to extrude the bevel block 202d into the limiting groove 202b, and compress the spring 202c, the spring 202c pushes the movable block 202h through the reaction force of the spring 202c, and then the fixed column 202e is pulled out to drive the fixed block 202g to move to the position abutting against the movable block 202h, so that the fixed block 202g and the movable block 202h form a tight whole, so as to extrude the bevel block 202d into the limiting groove 202b again to release the limiting of the fixed block 202g.

[0042] After maintenance: insert the fixing column 202e, extrude the fixing block to the bevel block 202d, the bevel block 202d clamps the fixing block 202g under the action of the spring 202c, so as to restore the normal state of the device.

[0043] In summary, through the cooperation of the migration platform body 100 and the auxiliary mechanism 200, not only can the migration vehicle be blocked in time when the vehicle slips, preventing the vehicle from rushing out of the migration platform and ensuring the safety of the equipment and the surrounding environment, but also the maintenance process of the blocking block 102 can be greatly simplified, the time and labor cost required for maintenance can be reduced, and the effect of reducing the risk of serious accidents caused by vehicle slipping and improving the stability and operability of the equipment can be achieved.
