Background technology
At present, the winding plant that car hosit adopted, be generally the parallel-axes gears reductor or the planet-gear speed reducer of fluid motor-driven, but be the constant-mesh formula, hoist and decline is power driven, work speed is restricted, especially when idle travel, can not effectively increase work efficiency, and still will keep certain energy consumption, be the raising of restriction car hosit hoisting operation efficient and the key factor that energy consumption reduces.
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.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is drg of the present utility model, clutch configuration figure.
1. HM Hydraulic Motor among the figure, 2. reductor, 3. reel, 4. rope wedge, 5. tie-plate, 6. braking hub, 7. power-transfer clutch, 8. drum shaft, 9. swivel coupling, 10. erection support, 11. brake cylinder, 12. brake push rod, 13. retarding spring, 14. left brake collar, 15. clutch hoof, 16. clutch oil cylinder, 17. bearing pin, 18. retracing spring, 19. clutch discs, 20. hinge bolt, 21. extension spring, 22. set screw, 23. joint, 24. oil pipe, 25. right brake collar, 26. brake holder, 27. support.
The specific embodiment
HM Hydraulic Motor 1 connects reductor 2, and (reductor can be a planetary reducer, also can be the parallel-axis type reductor), drum shaft 8 one ends connect reductor 2, the other end connects swivel coupling 9, reel 3 is linked to each other with braking hub 6 by tie-plate 5, and is bearing on the drum shaft 8 by antifriction-bearing box, and power-transfer clutch 7 is built in the braking hub 6, and be fixed on the drum shaft 8, rope wedge 4 is arranged on the reel 3.
Described power-transfer clutch 7 is made up of clutch discs 19, clutch hoof 15, clutch oil cylinder 16, retracing spring 18 etc., clutch discs 19 is connected on the drum shaft 8, clutch hoof 15 1 ends are hinged on the clutch discs 19, the other end links to each other with clutch oil cylinder 16, retracing spring 18 1 ends hang on the clutch discs 19, and the other end hangs on the clutch hoof 15.
(14,25 etc. form described drg by brake cylinder 11, brake push rod 12, retarding spring 13, left and right brake collar, left side brake collar 14 and the 25 usefulness extension springs 21 of right brake collar are suspended on braking hub 6 excircles, brake holder 26 is fixed on the car body, left side brake collar 14 is connected with hinge bolt 20 with right brake collar 25 upper ends, brake cylinder 11 connects brake push rod 12, retarding spring 13 is arranged on the brake push rod 12, and the lower end of right brake collar 25 and brake push rod 12 are hinged with brake holder 26.
HM Hydraulic Motor 1 is rotated, through reductor 2, driving drum shaft 8 rotates, when power-transfer clutch 7 combines with braking hub 6, reel 3 makes with drum shaft 8 and rotates, realize that hook lifting, clutch oil cylinder 16 are fixed on the clutch discs 19, after pressure oil enters clutch oil cylinder 16 by oil pipe 24, oil cylinder piston promotes push rod, clutch hoof 15 is opened with braking hub 6 combine, during clutch oil cylinder 16 drainings, by the retracing spring 18 of 15 of clutch hoof, clutch hoof 15 is resetted, break away from braking hub 6, reel 3 can freely rotate, and this also is the essential condition that realizes the gravity lowering function.Drg is a normally closed brake, and the tension force that leans on retarding spring 13 is with left and right brake collar (14,15) and the 6 tight pressings of braking hub, and the braking friction that produces between them is passed to turntable through brake holder 26, reaches the braking purpose to reel 3.During the normal operation operating mode, pressure oil enters clutch oil cylinder 16 by swivel coupling 9, the oil cylinder piston bar is overhanging, promote left and right clutch hoof 15 and be pressed in braking hub 6 inboards, this moment, pressure oil entered brake cylinder 11 compression brake springs 13 if promote bar handle, made left and right brake collar (14,15) break away from braking hub 6, pressure oil drives HM Hydraulic Motor 1 rotation simultaneously, drives reel 3 rotations.Realize fast playing function, move power-transfer clutch 6 handles, pressure oil drain charge in the clutch oil cylinder 16, clutch hoof 15 breaks away from braking hub 6 under the effect of retracing spring 18, reel 3 separates with drum shaft 8, and this moment is if step on brake pedal, pressure oil is opened drg, 3 on reel is in quick condition, and weight affects reel 3 fast rotational by steel rope under the effect of gravity, has realized that gravity transfers; This moment is if lift brake pedal, the pressure oil drain charge in the brake cylinder 11, and left and right brake collar (14,25) is held braking hub 6 tightly under the effect of retarding spring 13, reel 3 is braked.
