Cage door for mine hoisting

Abstract

The invention belongs to the field of mine vertical shaft hoisting equipment, and particularly relates to a cage door for mine hoisting. Guide rails for fixing safety doors are arranged on a cage and extend to the flat surface of the top of the cage from the bottoms of the opening sides of the cage so as to enable the safety doors to be pulled to the flat surface of the top of the cage from the opening sides of the cage; the turnings of the guide rails are of circular arc transition structures; a transmission device for driving the safety doors to move is arranged on the flat surface of the top of the cage and is powered by a power device; a front opening and a rear opening are formed in the cage; each opening is provided with the safety door; and the guide rails of the front opening side and the rear opening side of the cage are staggered on the flat surface of the top of the cage. The cage doors are interlocked with a shaft mouth car handing system; and after the cage is in place, the cage doors automatically open, thereby reducing the errors of manual operation. The potential energy generated during the up and down movement of the cage is stored by a power accumulator in the cage door so as to provide energy sources for the power device. The cage door is energy-saving and environmentally-friendly; and meanwhile, a latticed frame structure is adopted, so that the sight line of a cage riding person is not blocked.

Description

technical field [0001] The invention belongs to the field of mine shaft hoisting equipment, and in particular relates to a cage door used for mine hoisting. Background technique [0002] In the vertical shaft hoisting mine, the cage is an important equipment for mine hoisting. In order to facilitate the entry and exit of mine cars, both sides of the cage are open structures. In order to prevent people from falling into the shaft during manned operation, door curtains are added on both sides of the tank. [0003] The door curtain in the tank currently in use is just a simple door curtain welded with iron chains and steel pipes on the side of the cage entering and exiting the car. After the tank is stopped, it is lifted by hydraulic pressure or manually. The outer door curtain counterweight realizes the opening and closing of the tank door. This method requires the cage to run to a specific location at the wellhead to open the door beam, which is poor in practicability and has...

Problems solved by technology

[0003] The door curtain in the tank currently in use is just a simple door curtain welded with iron chains and steel pipes on the side of the cage entering and exiting the car. After the tank is stopped, it is lifted by hydraulic pressure or manually. The outer door curtain counterweight realizes the opening and closing of the tank door. This method requires the cage to run to a specific location at the wellhead to open the door beam, which is poor in practicability and has potential safety hazards. The manual lifting method affects the lifting efficiency and increases the workload of personnel. volume, increased number of workers

[0004] With the modernization of mine hoisting, the requirements for safety and efficiency continue to rise. In the case of a large number of people in the cage and high humidity in the shaft, the simple fence inside the tank can no longer meet the safety requirements of the tankers. Personnel bring safety hazards, how to ensure the safety of tankers, improve the environment of tankers, and improve transportation efficiency has become a major problem that needs to be solved urgently in cage transportation
