Abstract

The invention relates to a broken rope catching device, and belongs to the technical field of auxiliary equipment of a downhole aerial mancar of a coal mine. The invention aims to provide a device which can be used for clamping a broken rope in an extremely short time when a rope breaking phenomenon occurs. The broken rope catching device adopts the technical scheme that an upper wedge block shaft is mounted at the upper part of a box body, and a reaction arm shaft is mounted at the lower part of the box body; a first rope supporting wheel and a second rope supporting wheel are mounted at the bottom of the box body at intervals, and the mounting positions of the first rope supporting wheel and the second rope supporting wheel are higher than the position of the reaction arm shaft; a stopping arm is mounted on one side, on which the first rope supporting wheel is mounted, of the box body, and the stopping arm is located directly over a reaction arm; a protection hood is arranged at the end part of the stopping arm; an upper wedge block is mounted on the upper wedge block shaft, the reaction arm is in key-type connection with the reaction arm shaft through a support lug, a lower wedge block is mounted at one end, located in the box body, of the reaction arm, and a jamming groove in which a steel rope is jammed is formed in one end, outside the box body, of the reaction arm; the lower end of a lever linkage mechanism is connected with the reaction arm shaft, and the upper end of the lever linkage mechanism is connected with the upper wedge block shaft through a latch. The broken rope catching device disclosed by the invention is applied to the downhole aerial mancar of the coal mine.

Description

technical field [0001] The utility model relates to a broken rope arresting device, which belongs to the technical field of auxiliary equipment for overhead man-vehicles in coal mines. Background technique [0002] In the prior art, the trolley under the coal mine is widely used as a walking-replacing tool for miners. The diameter of the steel rope of the aerial vehicle is generally 24mm, but there is a danger of breaking the rope due to wear and fatigue during long-term work. Safety accidents caused by broken ropes occur from time to time, which pose a serious safety threat to underground production in coal mines. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art, and the technical problem to be solved is to provide a device that can clamp the broken rope in a very short time when the broken rope occurs. [0004] In order to solve the above-mentioned technical problems, the technical scheme adopted in the present invention: the...
