Abstract

The invention discloses a chain-type hydraulic hoist for lifting, which comprises a lifting hook, a hydraulic drive control part, a lifting part, a planetary reducer and a high-strength lifting chain; the hydraulic drive control part comprises a valve block, a hydraulic motor, a non-brake oil tube and a hydraulic brake; the lifting part comprises an end cover, a housing, a driving chain wheel, a locating bearing and a primary drive gear; the planetary reducer comprises a sun wheel shaft, a planetary gear, a planetary gear shaft, a planetary gear rack, a primary gear ring, a fixed gear, a secondary gear ring and a planetary reducer shell; the hydraulic hoist provides a control oil tube by a matched hydraulic system on mining machinery, and drives the planetary reducer by the hydraulic motor; the planetary reducer outputs a torque to drive a lifting driving chain wheel, and drives an annular lifting chain and a lifting hook device to lift and put down heavy objects, and also can be used for horizontally dragging the heavy objects (namely used as a hydraulic winch). The chain-type hydraulic hoist is suitable for downhole operation of coal mine, and has the advantages of being reasonable in structure, large in lifting ratio in equal volume, simple and convenient to operate, high in work efficiency, safe and reliable.

Description

(1) Technical field [0001] The invention belongs to the technical field of hoisting equipment, and in particular relates to a chain hydraulic hoist for hoisting which is matched with mining machinery and used underground in coal mines. (2) Background technology [0002] The hoist is an important part of the lifting equipment. The existing hoists include chain hoists, electric hoists, pneumatic hoists and hydraulic hoists. However, the use of hand chain hoists is labor-intensive and the work efficiency is low; when electric hoists are used in mines, explosion-proof measures must be taken to make them complex in structure and large in size; air hoists cannot be used in mines due to the limited air source conditions used, and its rated load is small; the traditional hydraulic hoist is driven by an emulsion motor, and its rated load is small; due to its own limitations, these types of hoists cannot be used well in mining machinery and equipment. At present, the hoisting equipme...
