Abstract
The utility model relates to a safety locking device of a main cable working vehicle. The safety locking device comprises a swing rod, the front end of the swing rod is hinged with a vehicle frame, and the rear end of the swing rod is provided with a sliding sleeve. A sliding shaft is matched with the sliding sleeve and can move horizontally along the sliding sleeve and simultaneously rotate. The sliding shaft is connected with a connecting rod which is provided with a handle, the front end of the connecting rod is hinged with a pulling rod, and the pulling rod is hinged on a squeezing block. The squeezing block is placed inside a horizontal placing groove on a locking block and hinged with the locking block. The locking block is provided with a clamping groove which is provided with a downward opening, and the clamping groove is clamped on a handrail steel wire rope downward. The horizontal placing groove is communicated with the inner side wall of the clamping groove, and the end portion of the squeezing block can extend into the clamping groove. When the squeezing block rotates to a position which is perpendicular to the side wall of the clamping groove from an inclined position which is inclined with the side wall of the clamping groove, the end portion of the squeezing block can tightly press the handrail steel wire rope inside the clamping groove to the outer side wall of the clamping groove. The safety locking device of the main cable working vehicle improves the safety of the main cable working vehicle, and is simple in structure, convenient to operate and high in reliability.

Main push-towing rope work car safety locking device of the present utility model includes a fork, the fork front end is hinged by horizontal horizontally hinged axle and vehicle frame, 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 rotate in sliding sleeve simultaneously; Sliding axle one end with one longitudinally connecting rod be connected, be provided with on the connecting rod 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 by pivot pin and latch, and the movement of pull bar can drive crushing block and rotate around pivot pin; Be provided with a draw-in groove that Open Side Down on the described latch, latch can be stuck in downwards on the handrail wire rope of bridge main push-towing rope both sides by draw-in groove; The resettlement groove of described level communicates with the inside wall of draw-in groove, the end of described crushing block can extend in the draw-in groove, when crushing block turned to the position vertical with the draw-in groove sidewall from the position with the draw-in groove sidewall slope, 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.
Described draw-in groove compresses the ditch tooth that is provided with concaveconvex structure on the lateral wall that contacts with the handrail wire rope, the frictional force when compressing to improve the handrail wire rope.
The utility model can carry out safe lock to vehicle frame in tool car parking maintenance process, prevent from hindering for some reason vehicle frame downslide when causing the tractive force forfeiture, the safety that has greatly improved the main push-towing rope work car, and it is simple in structure, easy to operate, reliability is high.
Description of drawings
Fig. 1 is plan structure schematic diagram of the present utility model;
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 locking device includes a fork 1, and the fork front end is hinged by horizontal horizontally hinged axle 2 and vehicle frame 3, 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 rotate in sliding sleeve simultaneously; Sliding axle 5 one ends with one longitudinally connecting rod 6 be connected, be provided with on the connecting rod 6 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 the movement of pull bar 8 can drive crushing block 9 and rotate around pivot pin 12; Be provided with a draw-in groove that Open Side Down 13 on the latch 10, latch 10 can be stuck in downwards on the handrail wire rope S of bridge main push-towing rope both sides by 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 turned to the position vertical with the draw-in groove sidewall from the position with the draw-in groove sidewall slope, 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 is provided with concaveconvex structure on the lateral wall that contacts with handrail wire rope S, the frictional force when compressing to improve the handrail wire rope.
Method of operating of the present utility model is:
In main push-towing rope work car walking process, 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, by rotational swing rod 1, transverse shifting sliding axle 5 and pivot link 6, draw-in groove on the latch 10 is stuck on the handrail wire rope, when at this moment if the tool car downslide occurs in barrier for some reason, by moving behind vehicle frame 3 drivening rods 6 and the pull bar 8, crushing block 9 is turned to the position vertical with the draw-in groove sidewall from the position with the draw-in groove sidewall slope, thereby handrail wire rope S is pressed on the lateral wall of draw-in groove, realize locking;
When tool car need to 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 by rotational swing rod 1, transverse shifting sliding axle 5 and pivot link 6, make latch 10 leave handrail wire rope S.
