Abstract

The utility model relates to a mine lifting hoist, which comprises a work brake 1, a reel 2, a foundation 3, an electric motor 4, a reduction gear 6 and a fluid strength pushing bar arrester 7. The utility model is characterized in that a reduction gear 5 is placed between the electric motor 4 and the reduction gear 6; the main structure of the reduction gear is of the general planet reduction gear structure. The utility model has the advantages that the structure is simple and the using is convenient, the performance is reliable and the cost is low; and the non-stage speed regulation is realized.

Description

The mechanical stepless speed-regulating winch

The utility model relates to a kind of mine hoisting winch.

At present, mine winch speed regulation device mostly adopts the electrical equipment gearshift.It changes resistance value by gear shift and realizes speed change, not only speed adjustable range limits to, the automatically controlled energy consumption of resistance is big, and resistance is automatically controlled, and influenced by the mine working environment bigger, particularly explosion-proof hoist, its electrical equipment gearshift accessory combination is many, and the split setting, battle array is bigger, cost up to 100,000 yuan/cover, the fault rate height, maintenance is complicated.

The purpose of this utility model provides a kind of easy to use, dependable performance, lower-cost mechanical stepless speed-regulating winch.

The purpose of this utility model is achieved in that it changes former winch electrical equipment gearshift is mechanical governor.The keystone configuration of this mechanical governor is universal planetary reduction gear structure.

The utlity model has following advantage:

1, widens speed adjustable range, realized infinite speed variation easily.

2, through-coupling, energy-conservation.

3, regulating mechanism alone becomes one, dismantles easy to assemblyly, easy to maintenance, has reduced working strength of workers, has improved labor efficiency.

4, because whole governor is connected by inside and outside tooth axle sleeve with hoist redution gear, can overcome because the decentraction that processing and assembling are caused.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model governor structure scheme drawing.

Fig. 3 is the utility model transmission principle figure.

Referring to Fig. 1,2, the utility model is mainly by service brake 1, reel 2, and base 3, electrical motor 4, retarder 6, fluid power pusher brake 7 is formed, and it is characterized in that between electrical motor 4 and retarder 6 governor 5 being set.Input shaft 8 outer ends and the electrical motor 4 of this governor 5 link, a sun wheel 9 is equipped with in the inner, satellite gear 10 joins with sun wheel 9 and inner gear 12, satellite gear 10 is assemblied in pinion carrier 11 the inners, the pinion carrier outer end is that governor 5 mouths and retarder 6 link, the inner gear 12 of governor 5 is fixed in the governor roll-shell 13, and by two bearing seats 14,15 that are fixed on the winch base 3, the two ends of support housing 13.A speed belt 16 that is fixed on the base 3 is housed at the middle part of housing 13 outside faces.This speed belt 16 is round, and the band skin is a steel band, and internal layer is wear-resisting asbestos tape.Steel band one end is fixed on the base 3, and the other end is equipped with one handle 17.By handle 17 reinforcings, make speed belt 16 embrace roll-shell 13, and can change the output speed of governor 5 according to the size of the application of force.Referring to Fig. 3, the moment of torsion of electrical motor 4 drives satellite gear 10 by the sun wheel on the input shaft 8 of governor 59 and rotates, and satellite gear 10 gives transmission of torque pinion carrier 11 output and inner gear 12 speed governing.When speed belt 16 did not add braking force, satellite gear 10 rotations drove inner gear 12 and shell 13 rotates, and pinion carrier 11 is not rotated, no-output.When speed belt 16 added ascending braking force, shell 13 rotating speeds stop at last, and the speed of pinion carrier 11 were exported with command speed at last by accelerating slowly by slack-off soon.
