Mine explosion-proof escalator

Abstract

The invention discloses a mine explosion-proof escalator, comprising an explosion-proof driving unit, an explosion-proof control cabinet, an explosion-proof overhauling handle and a truss, wherein the explosion-proof driving unit and the explosion-proof control cabinet are mounted in an upper machine room at the horizontal segment of the upper part of the truss, the explosion-proof overhauling handle is mounted in a lower machine room at the horizontal segment of the lower part of the truss, the explosion-proof driving unit comprises a turning gear, a protection device, an explosion-proof motor, an explosion-proof reduction gearbox and a driving sprocket, the turning gear and the protection device are mounted at the upper part of the explosion-proof motor, the explosion-proof motor is connected with the explosion-proof reduction gearbox, the driving sprocket is mounted on the explosion-proof reduction gearbox, and a brake and a brake monitoring device are mounted between the explosion-proof motor and the explosion-proof reduction gearbox. With the structure, the mine explosion-proof escalator can be used in the environments with explosive mixture gas containing methane and coal dust and is also applicable to humid shafts with accumulated water and environments with corrosive gases.

Description

technical field [0001] The invention relates to a manned hoisting device for mines, in particular to a mining escalator capable of operating in inclined shafts with an explosion-proof function. Background technique [0002] Usual underground excavation industry has been using hoisting devices such as monkey carts, man carts, hanging cages or cages to realize personnel's going down the well and going up the well. More than several commonly used mine personnel lifting equipments are all introduced on the winch in the winch house through the wire rope at the top through the pulley, and the operation of the wire rope is achieved by the rotation of the winch. Its result all adopts forced drive, and its security aspect is not very high, and the lifting efficiency is low in addition, and power consumption is bigger. The start and stop of the equipment is completely beyond the control of the passengers. In addition, there is no possibility of comfort considerations in the runnin...

AI Technical Summary

Problems solved by technology

As a result, forced drive is used, and its safety is not very high. In addition, the lifting efficiency is low and the power consumption is relatively large.

The start and stop of the equipment is completely out of control for the occupants

In addition, there is no possibility of comfort considerations in the operation process.

Under the mine, there are methane gas, explosive mixture gas, coal dust, damp, water and corrosive gas in the shaft, and geological phenomena such as floor drums, which have brought great difficulties to the improvement of mine hoisting devices.
