Safety lifting cabin for coal mine rescue

Abstract

The invention discloses a safe lifting cabin for coal mine rescue. The safe lifting cabin is characterized in that a plurality of guide walking anti-blocking mechanisms are arranged on the peripheral surface of a guide cabin at intervals in an array manner, so that the guide of the guide cabin can be effectively realized, the condition of blocking or unbalanced lifting is prevented, the smoothness and stability of lifting are effectively improved, meanwhile, a main controller can control the guide walking anti-blocking mechanisms according to the lifting force of a mine vertical rescue lifting system, and the main controller is configured to control the guide walking anti-blocking mechanisms to stretch out to conduct guiding, walking and anti-blocking driving actions only when the lifting force is larger than a threshold value under the lifting condition, the safe lifting cabin can be effectively controlled to act when guiding and anti-blocking are needed, so that the energy consumption is reduced, and the running smoothness of equipment is improved.

Description

technical field [0001] The invention belongs to the field of coal mines, in particular to a safety hoist cabin for coal mine rescue. Background technique [0002] In the process of coal mining, there may be spontaneous combustion disasters such as water, fire, and gas, which seriously threaten the lives of many miners. Coal mine safety has always been highly valued and various emergency measures have been taken to deal with mine disasters, such as setting up refuge chambers in coal mine roadways and installing underground movable rescue cabins. However, these emergency measures cannot provide direct rescue and escape channels for life rescue, and can only provide temporary shelters, and the trapped people still need to wait for further rescue. [0003] Using a safety lifting cabin for coal mine rescue to carry out mine disaster rescue is a new rescue method. It uses a pre-drilled shaft to directly lead from the ground to the mine for rescue, and the trapped people quickly r...

However, these emergency measures cannot provide direct rescue and escape channels for life rescue, and can only provide temporary shelters, and the trapped people still need to wait for further rescue.

[0003] Using a safety lifting cabin for coal mine rescue to carry out mine disaster rescue is a new rescue method. It uses a pre-drilled shaft to directly lead from the ground to the mine for rescue, and the trapped people quickly return to the ground by taking the rescue cabin. The mine rescue cabin is not functional enough to achieve rescue, and it has not yet achieved the purpose of safe, fast and reliable rescue. The parts are prone to deformation or collapse, which leads to the phenomenon of jamming and problems when the hoisting cabin is raised. At the same time, the hoisting cabin is prone to instability when it is lifted solely by wire ropes. The twisting makes the rescue cabin rotate, so the rescued people feel dizzy and other discomfort symptoms; in addition, during the rescue process, when the top is lifted and the bottom is touched, the safety buffer function is not set, so that the equipment will be damaged in the event of a collision , affecting the time of rescue; in the process of rescue, the rescue cabin often appears stuck in the wellbore, which leads to the failure of timely rescue and delays the rescue time of the victims
