Embodiment Construction

[0018] like Figure 1-Figure 3 As shown, the cage stall protection device includes a frame 1, a guide rope 2 hangs freely on both sides of the frame 1, and two guide ropes 2 are installed on one side of the frame 1. The guide wheels 3 held by the guide wheel 3 are installed with a centrifugal release device 4 on the rotating shaft of one of the guide wheels 3. The centrifugal release device 4 is composed of a casing 401, two radially symmetrical arrangements and sliding shafts 402 passing through the casing 401, fixed installation The sliding block 403 at the inner end of the sliding shaft 402 is composed of a spring 404 sleeved on the sliding shaft 402 and connected between the corresponding side sliding block 403 and the inner wall of the housing 401 . A catcher for clamping two guide ropes 2 and activated by a centrifugal releaser 4 is installed on the frame 1 . The catcher is composed of an oil pump 5 hingedly installed on the frame 1, an oil cylinder 6 connected to the o...

Abstract

The invention relates to a cage stall protection device. The cage stall protection device comprises a rack, wherein a guide rope freely falls from each of two sides of the rack; two guide wheels whichare arranged front and back and clamp the guide ropes on the corresponding sides are mounted on one side of the rack; a centrifugal releaser is mounted on a rotating shaft of one of the guide wheels;and a catcher which is used for clamping the two guide ropes and is started through the centrifugal releaser is mounted on the rack. The cage stall protection device can brake when the falling speedof a cage exceeds the standard specification requirement, and the cage is decelerated to stop, so that safety accidents caused by out-of-control falling of the cage are avoided, and the operation is safe and reliable.

Description

technical field [0001] The invention relates to a mine cage, in particular to a cage stall protection device. Background technique [0002] Cages are vehicles used to lift materials and personnel in vertical mines. At present, the cage only has a broken rope protection mechanism, that is, when the rope used for lifting the cage breaks, the broken rope protection mechanism installed on the cage brakes to prevent the cage from falling. However, during the lifting process of the cage, the falling speed of the cage often exceeds the requirements of the standard specification due to various reasons, which eventually leads to the loss of control of the cage falling, resulting in safety accidents and dangerous operations. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a cage stall protection device, which can brake when the falling speed of the cage exceeds the requirements of the standard specification, decelera...
