Dual-hook electric block

Abstract

The invention discloses a dual-hook electric block. The dual-hook electric block comprises a left shell, a planetary reducer, a left wall plate and a right wall plate; an electric drum, the planetaryreducer and a cylindrical roller bearing are arranged between the left shell and the left wall plate, the planetary reducer comprises a machine shell, a long shaft, a first-stage planetary wheel, a second-stage sun wheel, a second-stage planetary wheel, a first-stage inner gear ring, a second-stage inner gear ring, a planetary support and a bearing support, the long shaft is provided with a first-stage sun wheel engaged with the first-stage planetary wheel, the second-stage sun wheel is engaged with the second-stage planetary wheel, a lifting chain wheel, a protection cover, a connecting pin,a supporting rod and a guide wheel are arranged between the left wall plate and the right wall plate, the lifting chain wheel is fixedly connected with the planetary reducer, a bearing fixed plate, asquare pipe, a rigid coupler and a reduction motor are arranged between the right wall plate and the right shell, and the two ends of the rigid coupler are connected with the reduction motor and the planetary reducer. The dual-hook electric block has the beneficial effects of being high in positioning precision, capable of working under safety loads and good in waterproof and dustproof effect.

Description

【Technical field】 [0001] The invention relates to the technical field of electric hoists, in particular to the technical field of double-hook electric hoists. 【Background technique】 [0002] Electric hoist is a kind of special lifting equipment, which is mainly composed of motor, transmission mechanism, chain and sprocket, etc. It is usually installed on the crane and gantry crane. Electric hoist has the characteristics of small size, light weight, simple operation and convenient use. Therefore, electric hoists are often used in industrial and mining enterprises, storage terminals and other places. When using an electric hoist, the motor drives the sprocket to rotate, and the chain wound on the groove of the sprocket is controlled to be retracted to lift or release the object suspended by the chain. It turns out that two cranes and a single-hook electric hoist are used to realize the turning of large objects. This requires a very high degree of coordination in the operation...

AI Technical Summary

Problems solved by technology

It turns out that two cranes and a single-hook electric hoist are used to realize the overturning of large objects. This requires a very high degree of coordination in the operation of the cranes. After the center of gravity shifts, it will lead to poor positioning and even overturning accidents.

Some existing electric hoists have poor waterproof and dustproof effects. During the hoisting process, the power supply cable will interfere with the hoisting work, and it is difficult to control the weight of the hoisted object within the safe load range of the electric hoist. low efficiency
