a release device

Abstract

The invention discloses a disengagement device. The device comprises a capsule body, a plurality of anti-collision rods are connected around the capsule body, a plurality of observation windows are formed in the side walls of the capsule body, openings are formed in the side walls of the capsule body on the upper and lower sides of the anti-collision rods, connecting rods are arranged in the openings, two ends of the connecting rods penetrate through the openings to reach the two sides of the openings, the middle of the connecting rods are rotatably connected with the side walls of the capsulebody, clamping blocks are connected with one ends of the connecting rods, clamping grooves are formed in the side walls of the anti-collision rods, first springs are connected with the other ends ofthe connecting rods, fixing blocks connected with the other ends of the first springs are arranged on the inner walls of the capsule body, first opening holes are formed in the middle of the fixing blocks, first pull ropes are arranged in the first opening holes in a penetration mode, one ends of the first pull ropes are connected with the connecting rods, and the other ends of the first pull ropes are connected with rotary rollers rotatably connected with the side walls of the capsule body. According to the disengagement device, not only is the anti-collision effect of a rescue elevation capsule guaranteed, but also the clamped anti-collision rod can be disengaged rapidly to further guarantee safety of trapped personnel.

Description

technical field [0001] The invention relates to the technical field of rescue equipment, in particular to a release device. Background technique [0002] When the rescue hoisting cabin used for mine accidents is raised and lowered in the rescue passage, it may be stuck by the hole wall. In order to prevent the occupants in the rescue hoisting cabin from being trapped in the stuck cabin, most of the existing rescue hoisting cabins are equipped with two Secondary escape device, disengagement device is exactly a kind of secondary escape device. When the rescue lifting cabin is stuck, the occupants in the cabin operate the release device, which can separate the cabin of the rescue lifting cabin from its outer anti-collision components, so as to ensure that the occupants can return to the safe position on the well. At present, some disconnecting devices of the existing rescue hoist cabin connect the cabin body of the rescue hoist cabin with the side protection group through the ...

Problems solved by technology

The disengaging device of this structure requires the occupant to squat down to operate, and requires a lot of effort to pull out the pin shaft, which is time-consuming and labor-intensive

In addition, when a mine disaster occurs, rockfall may occur in the mine hole at any time. Once the rockfall gets stuck on the anti-collision assembly, the entire anti-collision assembly needs to be disengaged. In this way, the rescue lifting cabin will not be able to achieve the anti-collision effect when it continues to rise. Guaranteed, and then it is difficult to better protect the safety of people in the cabin
