Summary of the invention
The purpose of this utility model provides the winch that a kind of gravity is put soon, and this winch is to make car hosit when unloaded or little load, transfers suspension hook and relies on gravity to carry out, to improve work speed and to cut down the consumption of energy.
The purpose of this utility model is achieved in that this winch is made up of HM Hydraulic Motor, reductor, reel, drum shaft, power-transfer clutch, drg etc., HM Hydraulic Motor connects reductor, drum shaft one end connects reductor, the other end connects swivel coupling, reel is linked to each other with the braking hub by tie-plate, and be bearing on the drum shaft by antifriction-bearing box, power-transfer clutch places in the braking hub, and is fixed on the drum shaft.
Described power-transfer clutch is made up of clutch discs, clutch hoof, clutch oil cylinder, retracing spring etc., clutch discs is connected on the drum shaft, and clutch hoof one end is hinged on the clutch discs, and the other end links to each other with the clutch oil cylinder, retracing spring one end hangs on the clutch discs, and the other end hangs on the clutch hoof.
Described drg is made up of brake cylinder, brake push rod, retarding spring, left and right brake collar etc., left side brake collar and right brake collar are suspended on the braking hub excircle with extension spring, right brake band holder is fixed on the car body, left side brake collar is connected with hinge bolt with right brake collar upper end, brake cylinder connects brake push rod, retarding spring is arranged on the brake push rod, and the lower end of right brake collar and brake push rod and brake holder are hinged.
The utility model has the advantages that: can be by operating the clutch, reel is separated with drum shaft, this moment is if open drg, then reel can rotate freely under external force, realization gravity is transferred, and has increased work speed greatly, has improved work efficiency, transfer simultaneously in the process without any need for power, reduced a large amount of energy consumptions.
Below in conjunction with drawings and Examples the utility model is described.
