Abstract

The invention provides a slot disengagement protection device for a hoist wire rope pf a magnetic conveyor. The slot disengagement protection device comprises two main fulcrum bars positioned between a reel and a fixed pulley, wherein the two main fulcrum bars are erected on the ground; a link mechanism is arranged between the two main fulcrum bars and comprises two balance bars; each balance bar is hinged to the corresponding main fulcrum bar and comprises a first subsidiary bar and a second subsidiary bar which intersect to form an angle; the two second subsidiary bars are connected through a cross bar; the weights of the first subsidiary bars are larger than those of the second subsidiary bars; the cross bar is positioned under a wire rope; and a travel switch is arranged on each main fulcrum bar, and when the first subsidiary bars are in contact with the corresponding travel switches, the control loop of the reel is in an on state. As the balance bars are arranged, the travel switches are in the normally closed state, and the main control loop is kept connected; and when the wire rope is disengaged from a slot and presses the cross bar, the travel switches are turned off, the main control loop is disconnected, and equipment can stop immediately, and repair personnel can quickly handle the situation for reuse.

Description

technical field [0001] The invention relates to the field of magnetic conveyors, in particular to a protective device for hoisting wire ropes of magnetic conveyors. Background technique [0002] The magnetic conveyor, also known as the stacker, is a lifting device for the upper and lower roller tables of steel plates. Its overall structure and working principle are similar to those of bridge cranes, but the span and lifting height are different, and there is no trolley traverse mechanism. In the production process, due to improper operation and other reasons, the wire rope of the hoisting mechanism often escapes from the drum or the fixed pulley. Most of the time, the operator cannot find out in time and continue to operate, thus directly causing the wire rope of the drum to fall out of the groove and damage the bearing seat. , wire rope breakage, fixed pulley flanging and other equipment accidents. After the wire rope de-grooving equipment accident occurs, the maintenance ...
