Multi-connecting rod heavy-load rope locking device

Abstract

The invention aims to provide a multi-connecting rod heavy-rod rope locking device, which comprises a front cover plate, a rear cover plate, a holding-locking device, a force transferring transition frame and a rope locking hydraulic cylinder, wherein the top of the rear cover plate is vertically and fixedly connected with guide rods, and the rear side is fixedly connected with the rope locking hydraulic cylinder; the holding-locking device includes a fixing frame, a movable rope locking block and a plurality of first rope locking connecting rods, one side of the fixing frame is fixedly connected with a boss, the boss is connected with a corresponding hinge pin end at the same side of the movable rope locking block through the first rope locking connecting rod, the left and right sides ofthe bottom surface of the force transferring transition frame are respectively connected with the upper ends of second rope locking connecting rods, the lower ends of the second rope locking connecting rods are connected with the upper part of the movable rope locking block through hinge pins, and a cylinder rod of the rope locking hydraulic cylinder is connected with the bottom surface of a rectangular plate through a hinge pin. The multi-connecting rod heavy-load rope locking device solves a problem of unstable rope locking force or difficult rope loosening of the existing lifting steel wirerope locking device under a heavy load working condition.

Description

technical field [0001] The invention belongs to the field of hoisting equipment, and in particular relates to a locking and fixing device for hoisting wire ropes used for maintenance of shaft hoisting system components. Background technique [0002] The safe locking and fixing of the hoisting wire rope is an extremely critical link in the maintenance of the shaft hoisting system, such as: adjustment and replacement of the hoisting wire rope, maintenance of the sky wheel, hoisting container, hoisting winch, tail rope and other components, etc. These operations inevitably require Lift the wire rope for locking or fixing with load. [0003] With the mining of shallow surface resources for many years and becoming increasingly depleted, heavy-duty, deep shafts, and high-speed hoisting mines are bound to become the dominant mine production in the future. However, the heavy-duty deep well hoisting wire rope has a large diameter and self-weight, and the alternating loads such as be...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a multi-link heavy-duty locking rope device to solve the problem of unstable locking force or difficulty in loosening the rope existing in the existing hoisting wire rope locking device under heavy-load working conditions; The unreasonableness of the device causes production safety accidents such as slipping rope and damaged rope when the hoisting wire rope is locked; it can realize the non-destructive and reliable locking of the hoisting wire rope, and complete the off-position conveniently and quickly, so as to meet the requirements of the existing heavy-duty deep shaft hoisting system Requirements for timely replacement and maintenance of components
