Coal mine vertical shaft combined hoisting system

Abstract

The invention provides a coal mine vertical shaft combined hoisting system. The system comprises a cage hosting subsystem, a skip bucket hoisting subsystem and a sinking headframe; the cage hosting subsystem is mainly used for lifting all constructors and putting down goods and materials; the skip bucket hoisting subsystem is mainly used for completing lifting of coal and waste rock; the cage hosting subsystem and the skip bucket hoisting subsystem do independent work, and the constructors simply, conveniently and rapidly go up and down; lifting of the coal and the waste rock cannot be disturbed, and the process of coal and waste rock lifting by the skip bucket hoisting subsystem is high in automation degree; and the lifting speed is high, the lifting number is large, the efficiency is high, and the construction requirement of modern coal mine construction can be met.

Description

technical field [0001] The invention relates to a coal mine transportation technology, in particular to a coal mine shaft mixing lifting system. Background technique [0002] In the basic construction process of coal mines, after the construction of the vertical shaft shaft to the end, the construction direction is changed from the original top-down direction to the horizontal direction. The construction personnel need to enter and exit the level road through the shaft, and the materials and materials also need to be lowered to the level road through the shaft. Therefore, how to realize the lifting of the construction personnel, the lowering of materials and materials, and the lifting of coal and gangue in the shaft need to be considered during the construction process. a key question. [0003] At present, the cage lifting system is mainly used to realize the lifting of construction personnel, the decentralization of materials and materials, and the lifting of coal and gang...

AI Technical Summary

Problems solved by technology

[0004] However, with the substantial increase in the level of mechanization, the construction technology of using comprehensive roadheaders for level roadway excavation has matured, and the monthly footage has been increased from the original 50-100 meters to nearly 1,000 meters, and the monthly footage of the mine has been increased from the original 500- 1,000 meters to nearly 3,000 meters, and when using the existing cage lifting system to lift coal and gangue, it needs to be loaded into mine cars to lift, and the lifting speed and lifting quantity are greatly limited. The decentralization of the cage will also cause some interference to the lifting of coal and gangue. Therefore, the existing cage lifting system can no longer meet the construction needs of my country's coal mine construction.
