Abstract

The invention relates to a dual-drum elevator. A gear (D), a steering gear and a driven gear are installed on one drum shaft. Ropes are installed on drums. Drum shafts are connected with the drums. A gear (D) is installed on the other drum shaft. A first-stage speed reducing mechanism is connected with a motor. A driving main shaft is connected with the first-stage speed reducing mechanism. A gear (A) outside a rack is installed on the driving main shaft. The gear (A) is engaged with two driven gears which are respectively installed on two driven shafts on the rack. One driven gear is engaged with the steering gear which is installed on a steering shaft on the rack. The steering gear is engaged with the gear (D) which is installed on one drum shaft. The other driven gear is engaged with the gear (D) which is installed on the other drum shaft. The dual-drum elevator provided by the invention has the advantages that the transmission ratio is large, the structure is compact, the twisting force is large, the transmission is stable, the noise is low, the goal of safely and reliably lifting objects is achieved, the effect of synchronous lifting is realized, the dual-drum elevator can be widely used in the construction industry, the gantry crane industry and the door industry, the size is small and the service life is long.

Description

A kind of double-drum hoisting machine

Technical field

The present invention relates to the lifting equipment field, relate in particular to a kind of hoisting machine.

Background technology

The defectives such as existing crane lifting equipment adopts the electric block lifting to go real the sight mostly, and the ubiquity volume is large, rope roll long, swing property is large, poor stability, service life are short can't be seen the Synchronous lifting problem of building industry in fact.

Summary of the invention

The defects that exists in order to overcome existing crane lifting equipment the invention provides and a kind ofly exports that torque is large, safe and reliable, the double-drum hoisting machine of long service life.

The technical scheme that the present invention adopts for achieving the above object is: a kind of double-drum hoisting machine, drum shaft is equipped with gear and steering gear, driven gear, rope is contained on the reel, drum shaft is connected with reel, gear is housed on the drum shaft, first order speed reduction gearing is connected with motor, drive shaft is connected with first order speed reduction gearing, the outer gear of frame is contained on the drive shaft, gear and be contained in the driven gear engagement of being equipped with on the driven shaft on the frame, driven gear and be contained in steering gear engagement on the steering shaft on the frame, driven gear and be contained in steering gear engagement on the steering shaft on the frame, the gear engagement of being equipped with on steering gear and the drum shaft, the gear that is equipped with on driven gear and drum shaft engagement.

Double-drum hoisting machine hoisting crane of the present invention, the purpose of the lifting object that transmitting ratio is large, compact conformation, torque forces are strong, stable drive, noise are low, safe and reliable, realize synchronous ascending, can be used widely at building industry, gantry crane, Men Yejun: volume is little, long service life.

Description of drawings

Fig. 1 is the constructional drawing of double-drum hoisting machine of the present invention.

Fig. 2 is the constructional drawing of running part assembly of the present invention.

The specific embodiment

Double-drum hoisting machine structure of the present invention is equipped with rope drum assembly and transmission component as depicted in figs. 1 and 2 on the frame, the rope drum assembly comprises: reel 7, be contained in the rope 9 on the reel 7, and and on the drum shaft 6 that reel 7 links to each other gear D is housed respectively.Transmission component comprises 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 the driven gear B that is equipped with on the driven shaft 4 on the frame and gnaw and close, driven gear B and be contained in the fine engagement of steering gear C on the steering shaft 5 on the frame.The gear D engagement of being equipped with on steering gear C and the drum shaft 6, the gear D that is equipped with on driven gear B and the drum shaft 6 engagement.Rope guide 8 is housed on the reel 7, and rope guide makes tightening up of steel rope rule tired and loosen, and when two rope guides moved toward both sides, steel rope was put, and electric block descends, and when mobile, steel rope tightens up toward middle for two rope guides, and electric block rises.First order speed reduction gearing 2 is the flexible rim member that sun wheel and pinion carrier are floated, 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 larger transmitting ratio.Double-drum hoisting machine of the present invention is that the rotation that realizes like this motor 1 drives 2 rotations of first order speed reduction gearing, 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 rotate, gear D drives drum shaft 6 and rotates, drum shaft 6 band movable reels 7 rotate, and the rope 9 on the reel 7 rises or descends and is with animal body to do synchronous landing campaign like this.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 structure of sun wheel and pinion carrier, satellite gear in the primary speed-down mechanism that adopts, and reduced the live load of gnawing when closing, reduced noise, stationarity is good, thereby the purpose of the lifting object that realize that transmitting ratio is large, compact conformation, torque forces is strong, stable drive, noise are low, safe and reliable, realize synchronous ascending, can be used widely at building industry, gantry crane, Men Yejun, volume is little, long service life.
