Electric hoist

Abstract

The invention discloses an electric hoist. The electric hoist comprises a main shaft, a driver, a speed reducer, an overrunning clutch, a rope winding shaft and a clutch, wherein two ends of the mainshaft are fixed, the driver, the speed reducer, the overrunning clutch and the clutch are sequentially connected and connected onto the main shaft in a sleeving mode, the driver comprises a rotation shaft connected with the main shaft in a sleeving mode, the rotation shaft is of a hollow structure, the driver is electrified so as to drive the rotation shaft to rotate, the rotation shaft is connected with the speed reducer, the overrunning clutch comprises a planet carrier B connected onto the main shaft in a sleeving mode and a plurality of planet wheels B arranged on the planet carrier B, anoutput end of the speed reducer passes through the planet carrier B and becomes a sun wheel of the planet wheels B, the speed reducer comprises an inner gear ring part, the inner gear ring part is engaged with the planet wheels B, a rope is arranged on the rope winding shaft, the driver, the speed reducer, the overrunning clutch and the clutch are arranged in the rope winding shaft, and the planetcarrier B is connected with the wire winding shaft through a single-direction rotation structure.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an electric elevator. Background technique [0002] Modern society is developing rapidly. In recent years, high-rise buildings have become more and more common, and there are many high-rise buildings in major cities. While we are enjoying the entertainment life in the economic era with highly developed technology, the safety problems of many high-rise buildings are gradually revealed. [0003] In addition, currently in alpine exploration and high-rise operations, equipment such as ropes, safety belts, and rope descenders are mainly used. In terms of landing control of the original product, as long as the operation is careless and unskilled, if the rope encounters water or oil or the equipment fails, it will be very dangerous. In terms of ascent, there must be external forces to pull up or climb the rope with difficulty, and it is difficult to take it when going out and it is inconveni...

AI Technical Summary

Problems solved by technology

In terms of ascent, there must be external forces to pull up or climb the rope with difficulty, and it is difficult to carry and recycle when going out.

The current high-rise escape products use rope buffers. During the landing process, the speed cannot be controlled independently. In a complex environment, it is difficult to avoid obstacles, unable to stop and rise in the air autonomously, and it is easy to get stuck in the rope.
