Problems solved by technology

In order to accurately transmit torque, it is necessary to strictly control the backlash and gap difference between the meshing teeth of the tooth block and ring gear, and it is difficult to install and adjust, and it is difficult to guarantee the high precision requirements of all teeth at the same time
[0008] In order to complete the disengagement and meshing of the gear block, the gear block, moving hub, toggle ring and other parts need to be installed on the wheel hub. The structural size of the main shaft and the overall assembly of the main shaft device are increased, and the weight of the entire main shaft device is increased.

Abstract

The invention discloses a multi-oil-cylinder rope adjusting clutch for a single-rope winding type elevator. The multi-oil-cylinder rope adjusting clutch for the single-rope winding type elevator is arranged on a main shaft of the elevator and comprises a traveling barrel rope adjusting side hub, a bearing, a baffle block, a connecting bolt, a rope adjusting hub, an inner gear ring, a rope adjusting oil cylinder assembly, a fixed disc, a spring assembly and a travel detection device, the traveling barrel rope adjusting side hub is arranged on the main shaft through the bearing, and the inner gear ring is arranged on an outer gear shaft sleeve formed by the traveling barrel rope adjusting side hub and the rope adjusting hub through inner teeth; and a travel switch is arranged on a sliding rod support and transmits a sliding rod travel signal to an electric control system. The rope adjusting clutch is convenient to machine, requires relatively small number of parts, and is relatively short in assembly size chain, convenient to install and adjust, compact in structure, small in occupied space, light in weight, safe and stable.

Description

technical field [0001] The invention relates to the technical field of mine hoists, in particular to a multi-cylinder rope adjustment clutch for a single-rope winding hoist. Background technique [0002] Mine hoist is one of the important and key equipment in mines. It is mainly used in coal mines, metal mines and non-metal mines for hoists and decentralized personnel to lift coal, ore, and transport materials and equipment. It is an important means of transportation to connect the well and the underground. It occupies a very important position in the mine and is an important throat equipment of the mine. [0003] At present, the types of hoists in use are mainly multi-rope friction hoists and single-rope winding hoists. The rope adjustment clutch is only used for the single-rope double-tube winding hoist, and it is an extremely critical component. For the single-rope double-drum hoist, the swimming drum can rotate relatively through the bearing bush and the main shaft, a...
