Background technology
Main push-towing rope work car is a kind of device for main rope of suspension bridge maintenance, in its running by draw-gear drive vehicle frame along main push-towing rope climb or under remove, main push-towing rope work car will be at maintenance position parking maintenance, when catastrophic failure occurs to glide, have and can not carry out effective locking to vehicle frame, the ship that the personnel's vehicle on the personnel for main push-towing rope service work, equipment, below bridge floor and the water surface are travelled causes the safety danger side of body.There is complex structure, use the defects such as inconvenience, poor reliability in the safety locking device of existing main push-towing rope work car.
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 locking device is provided.
Main push-towing rope work car safety locking device of the present invention includes a fork, fork front end is hinged by horizontal horizontally hinged axle and vehicle frame, fork rear end has a horizontal sliding sleeve, a horizontal sliding axle coordinates with sliding sleeve and can move along sliding sleeve transverse horizontal, can in sliding sleeve, rotate simultaneously; Sliding axle one end with one longitudinally connecting rod be connected, on connecting rod, be provided with can before and after the handle of drive link, connecting rod front end is hinged with a pull bar, pull bar front end is hinged on a crushing block; Crushing block is arranged in the resettlement groove of a level on latch and hinged by pivot pin and latch, and the movement of pull bar can drive crushing block to rotate around pivot pin; On described latch, be provided with a draw-in groove that Open Side Down, 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 draw-in groove, when crushing block turns to the position vertical with draw-in groove sidewall from the position with draw-in groove sidewall slope, the end of crushing block can be pressed on the handrail wire rope in draw-in groove on the lateral wall of draw-in groove.
Described draw-in groove compresses with handrail wire rope the ditch tooth that is provided with concaveconvex structure on the lateral wall contacting, the frictional force while compressing to improve handrail wire rope.
The present invention can carry out safe lock to vehicle frame in tool car parking maintenance process, and while preventing from causing tractive force to be lost because of fault, vehicle frame glides, the safety that has greatly improved main push-towing rope work car, and it is simple in structure, easy to operate, reliability is high.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram 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 locking device includes a fork 1, and 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 coordinates with sliding sleeve 4 and can move along sliding sleeve transverse horizontal, can in sliding sleeve, rotate simultaneously; Sliding axle 5 one end with one longitudinally connecting rod 6 be connected, on 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 a crushing block 9; Crushing block 9 is arranged in the resettlement groove 11 of a level on 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 to rotate around pivot pin 12; On latch 10, be provided with a draw-in groove that Open Side Down 13, 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 draw-in groove, when crushing block 9 turns to the position vertical with draw-in groove sidewall from the position with draw-in groove sidewall slope, the end of crushing block 9 can be pressed on the handrail wire rope S in draw-in groove 13 on the lateral wall of draw-in groove.Draw-in groove 13 compresses with handrail wire rope S the ditch tooth 14 that is provided with concaveconvex structure on the lateral wall contacting, the frictional force while compressing to improve handrail wire rope.
Method of operating of the present invention 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 latch 10 is stuck on handrail wire rope, if while at this moment gliding because of fault generation tool car, by moving after vehicle frame 3 drivening rods 6 and pull bar 8, crushing block 9 is turned to the position vertical with draw-in groove sidewall from the position with 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, make connecting rod 6 and pull bar 8 reaches, crushing block 9 is turned over to certain angle, 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.
