Summary of the invention
Technical problem to be solved by this invention is, a kind of simple in structure, easy to operate, locking is reliable, safety is good main push-towing rope work car safety lock locking apparatus is provided.
Main push-towing rope work car safety lock locking apparatus of the present invention includes a fork; The fork front end is hinged with vehicle frame through horizontal horizontally hinged axle; The fork rear end has a horizontal sliding sleeve; A horizontal sliding axle cooperates with sliding sleeve also and can move along the sliding sleeve transverse horizontal, can in sliding sleeve, rotate simultaneously; Sliding axle one end with one longitudinally connecting rod be connected, connecting rod be provided with can before and after the handle of drive link, the connecting rod front end is hinged with a pull bar, the pull bar front end is hinged on the crushing block; Crushing block is arranged in the resettlement groove of a level on the latch and hinged through pivot pin and latch, and pull bar mobile can drive crushing block and rotate around pivot pin; Said latch is provided with a draw-in groove that Open Side Down, and latch can be stuck in downwards on the handrail wire rope of bridge main push-towing rope both sides through draw-in groove; The resettlement groove of said level communicates with the inside wall of draw-in groove; The end of said crushing block can extend in the draw-in groove; When crushing block from the rotated position of draw-in groove sidewall slope during to the position vertical with the draw-in groove sidewall, the end of crushing block can be pressed on the handrail wire rope in the draw-in groove on the lateral wall of draw-in groove.
Said draw-in groove compresses the ditch tooth that the lateral wall that contacts is provided with concaveconvex structure with the handrail wire rope, the frictional force when compressing to improve the handrail wire rope.
The present invention can carry out safe locking to vehicle frame in tool car parking maintenance process, prevent that failover from causing tractive force when forfeiture vehicle frame to glide, the safety that has improved main push-towing rope work car greatly, and it is simple in structure, easy to operate, reliability is high.
Description of drawings
Fig. 1 is a plan structure sketch map of the present invention;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is that the B of Fig. 1 is to local enlarged diagram.
The specific embodiment
As shown in the figure, this main push-towing rope work car safety lock locking apparatus includes a fork 1, and the fork front end is hinged with vehicle frame 3 through horizontal horizontally hinged axle 2, and fork 1 rear end has a horizontal sliding sleeve 4; A horizontal sliding axle 5 cooperates with sliding sleeve 4 also and can move along the sliding sleeve transverse horizontal, can in sliding sleeve, rotate simultaneously; Sliding axle 5 one ends with one longitudinally connecting rod 6 be connected, connecting rod 6 be provided with can before and after the handle 7 of drive link, connecting rod 6 front ends are hinged with a pull bar 8, pull bar 8 front ends are hinged on the crushing block 9; Crushing block 9 is arranged in the resettlement groove 11 of a level on the latch 10 and passes through a pivot pin 12 hinged with latch 10, and moving of pull bar 8 can drive crushing block 9 around pivot pin 12 rotations; Latch 10 is provided with a draw-in groove that Open Side Down 13, and latch 10 can be stuck in downwards on the handrail wire rope S of bridge main push-towing rope both sides through draw-in groove; The resettlement groove 11 of level communicates with the inside wall of draw-in groove 13; The end of crushing block 9 can extend in the draw-in groove; When crushing block 9 from the rotated position of draw-in groove sidewall slope during to the position vertical with the draw-in groove sidewall, the end of crushing block 9 can be pressed on the handrail wire rope S in the draw-in groove 13 on the lateral wall of draw-in groove.Draw-in groove 13 compresses the ditch tooth 14 that the lateral wall that contacts is provided with concaveconvex structure with handrail wire rope S, the frictional force when compressing to improve the handrail wire rope.
Method of operating of the present invention is:
Garage is walked in the process in main push-towing rope work, and latch 10 is away from handrail wire rope S;
When upkeep operation is carried out in the parking of main push-towing rope work car; Through rotational swing rod 1, laterally move sliding axle 5 and pivot link 6, the draw-in groove on the latch 10 is stuck on the handrail wire rope, if when the tool car of failover generation at this moment glides; By moving behind vehicle frame 3 drivening rods 6 and the pull bar 8; With crushing block 9 from the rotated position of draw-in groove sidewall slope to the position vertical with the draw-in groove sidewall, thereby handrail wire rope S is pressed on the lateral wall of draw-in groove, realize locking;
When tool car need be walked again, driving handle 7 forward, made connecting rod 6 and pull bar 8 reaches; Crushing block 9 is turned over certain angle; The handrail wire rope is unclamped, and then through rotational swing rod 1, laterally move sliding axle 5 and pivot link 6, make latch 10 leave handrail wire rope S.
