Embodiment Construction

[0008] The structure of the double-drum lifting elevator of the present invention is as follows: figure 1 and figure 2 As shown, the frame is equipped with a rope reel assembly and a transmission assembly, and the rope reel assembly includes: a reel 7, a rope 9 mounted on the reel 7, and a gear is respectively arranged on the reel shaft 6 connected to the reel 7 d. The transmission assembly includes a motor 1, a first-stage reduction mechanism 2 connected to the motor 1, and a drive spindle 3 connected to the first-stage reduction mechanism 2. The gear A outside the frame is mounted on the drive spindle 3, and the gear A and the drive shaft are mounted on the frame. The driven gear B mounted on the driven shaft 4 on the top is engaged, and the driven gear B is meshed with the steering gear C on the steering shaft 5 mounted on the frame. The steering gear C meshes with the gear D mounted on the spool shaft 6 , and the driven gear B meshes with the gear D mounted on the spool...

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

technical field [0001] The invention relates to the field of hoisting machinery equipment, in particular to a hoisting elevator. Background technique [0002] Most of the existing lifting equipment adopts electric hoists for lifting, which generally have defects such as large volume, long rope drum, large swing, poor stability, and short service life, which cannot realize the synchronous lifting problem of the construction industry. Contents of the invention [0003] In order to overcome the above-mentioned defects in the existing lifting equipment, the present invention provides a double-drum lifting lift with large output torque, safety, reliability and long service life. [0004] The technical scheme adopted by the present invention to achieve the above object is: a double-drum lifting elevator, the drum shaft is equipped with gears, steering gears, and driven gears, the rope is installed on the drum, and the drum shaft is connected to the drum , the reel shaft is equi...
