Abstract

The utility model relates to a double-drum hoisting machine which comprises a frame. A rope drum component and a transmission component are arranged on the frame, wherein drum shafts (6) and (6') of the rope drum component are provided with gears D and D' which are respectively engaged with a steering gear C and a driven gear B' of the transmission component. The utility model has the advantages that a motor drives two drums with the same rotating speed and opposite rotating directions; an adopted first-level speed reduction mechanism is designed into a flexible rim structure of a sun gear and floated planet carriers with uniformly distributed loads among planet gears; and dynamic loads during engaging are reduced; noise is lowered, and the stability is good; consequentially, the utility model achieves the purposes of large transmission ratio, compact structure, strong twisting force, steady transmission, low noise and safe and reliable object lifting; synchronous lifting is realized, and the machine is widely applied to the construction industry, gantry cranes and the door industry; and the machine has small volume and long service life.

Description

Double-drum hoisting machine

Technical field

The utility model relates to the hoisting crane technical field, a kind of specifically double-drum hoisting machine.

Background technology

At present, domestic lifting industry gig (elevator) adopts the electric block lifting to go reality to see mostly, defectives such as the ubiquity volume is big, rope roll is long, swing property is big, poor stability, service life are short, especially in the door industry, lifting problem such as building industry etc. synchronously can't be seen always in fact.

The utility model content

The purpose of this utility model is that a kind of increasing by secondary speed-reducing of design turned round, and obtains a big output torque, thereby realizes hoisting synchronously, and is safe and reliable, the double-drum hoisting machine that increases the service life.

The utility model double-drum hoisting machine, comprise: frame, rope drum assembly and transmission component are housed on the frame, and the

drum shaft

6,6 of rope drum assembly ' be equipped with gear D, D ', gear D, D ' are meshed with steering gear C, the driven gear B ' of transmission component respectively.

The rope drum assembly comprises: reel 7,7 ', be contained in reel 7,7 ' on rope 9,9 ', 9 ", 9 " ', with the

drum shaft

6,6 of reel 7,7 ' link to each other '; Drum shaft 6,6 ' on gear D, D ' are housed respectively.

Transmission component, comprise: motor 1, the first order speed reduction gearing 2 that links to each other with motor 1, the drive shaft 3 that links to each other with first order speed reduction gearing 2, the outer gear A of frame is contained on the drive shaft 3, gear A and be contained in driven

shaft

4,4 on the frame ' on driven gear B, the B ' engagement of being equipped with, driven gear B and the steering gear C that is contained on the steering shaft 5 on the frame mesh.

The engagement of the gear D that is equipped with on steering gear C and the drum shaft 6, driven gear B ' and drum shaft 6 ' on the gear D ' engagement of being equipped with.

Reel 7,7 ' on be equipped with rope guide 8,8 ', 8 ", 8 " ', rope guide makes tightening up of steel rope rule and loosens, when two rope guides move toward both sides, steel rope is put, and electric block descends, and two rope guides are toward middle when mobile, steel rope tightens up, and electric block rises.

First order speed reduction gearing 2 is the flexible wheel rim member that sun wheel and pinion carrier are floated, and this member is by the manufacturing of Shanghai Hua Lumen industry Co., Ltd, and its model is HL-DJ-00-01～HL-DJ-00-08.

Motor 1 is the YEZ series cone rotor brake motor that Nanjing specific type of electric machine factory produces and sells.

Motor 1 by first order speed reduction gearing 2 slow down increase turn round after, turn round through slowing down to increase for the second time again, make elevator when strengthening torsional forces, obtain bigger transmitting ratio.

The utility model double-drum hoisting machine is achieved in that the rotation of motor 1 drives first order speed reduction gearing 2 and rotates, the gear A that is contained on the drive shaft 3 is rotated, driven gear B drives steering gear C and rotates, driven gear B ', steering gear C driven gear D ', D rotate, gear D, D ' drive drum shaft 6,6 ' rotation, drum shaft 6,6 ' drive reel 7,7 ' rotation, like this reel 7,7 ' on rope 9,9 ', 9 ", 9 " ' rise or descend drive object and do synchronous landing campaign.

The advantage of the utility model double-drum hoisting machine is: two reels that rotating speed is identical, rotation direction is opposite of a driven by motor, be designed to load uniform distribution between the unsteady flexible rim construction of sun wheel and pinion carrier, satellite gear in the first class reducer structure that adopts, and the live load when having reduced engagement, reduced noise, stationarity is good; Thereby the purpose of the lifting object that realize that transmitting ratio is big, compact conformation, torque forces is strong, stable drive, noise are low, safe and reliable realizes hoisting synchronously, can be used widely at building industry, gantry crane, Men Yejun; Volume is little, long service life.
