An anti-fall skip tail rope suspension device and tail rope anti-fall method

Abstract

The invention relates to an anti-drop skip tail rope suspension device and an anti-drop method for a tail rope. An integrated flange is arranged at the bottom of a suspender, a hollow steel barrel sleeves from the top of the suspender, and an outer lug boss at the bottom of the hollow steel barrel is connected with an upper plate of a rotating fork by bolts; the inner diameter of the hollow steel barrel is larger than that of the flange of the suspender, and a 1 to 2 centimeters gap remains between the bottom of an inner lug boss of the top of the hollow steel barrel and the top of the flange; when the gap is reduced to less than 1 centimeter, a proximity switch installed for measuring the gap immediately starts an audible and visual alarm to remind people of performing safety inspection; if the gap is reduced to 0, the inner lug boss at the top of the hollow steel barrel is hung on the flange of the suspender to immediately bear the weight of the tail rope and prevent the tail rope dropping so as to avoid a mine hoisting accident and guarantee the mine safety production.

Description

technical field [0001] The invention relates to a component of mine hoisting equipment, in particular to an anti-fall skip tail rope suspension device and a tail rope anti-fall method. Background technique [0002] In mining operations, a multi-rope friction hoist is usually used to pull the skip to lift the ore underground. In order to balance the weight of the steel wire rope for lifting the skip, two steel wire tail ropes are usually hung between the bottoms of the two skips to balance the lifting of the skip. weight of the wire rope. Under the repeated action of heavy loads in the existing skip tail rope suspension device, there have been safety accidents in which the connectors loosened and the tail rope fell. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fall-proof skip tail rope suspension device and a tail rope anti-fall method, which can prevent the tail rope from falling and avoid mine hoisting acc...
