Abstract

The invention provides a constant brake force anti-falling catching device and a constant brake force anti-falling catching method for a rigid cage guide of a mine. The catching device mainly comprises a bottom plate, a wedge box fixed on the bottom plate through bolts, a wedge seat, a sliding wedge, guiding strips on two sides of the wedge seat, rollers, a holding rack, a spring bolt for connecting the wedge seat and the wedge box, and a belleville spring sleeved on the spring bolt, wherein the wedge seat and the sliding wedge are symmetrically arranged on two inner sides of the wedge box; and the rollers and the holding rack are arranged between the wedge seat and the sliding wedge. When a rope is broken, a main pull rod falls, the overhung end of a shift lever is lifted, so that the sliding wedge moves upwards along the tracks of the guiding strips to be in contact with and extruded with the rigid cage guide to generate horizontal brake force, and the wedge seat compresses the belleville spring; and the pressure of the belleville spring exerted on the wedge seat is kept constant, so that the falling cage decelerates with a constant braking deceleration under the action of constant brake force, and finally is supported by the rigid cage guide. Therefore, the structure is compact; the brake is reliable; the horizontal brake force is constant and adjustable; and the effect is good.

Description

A kind of anti-fall device and method of arresting of permanent braking force that is used for the mine rigid cage guide
Technical field
The present invention relates to a kind of anti-fall device and method of arresting of permanent braking force that is used for the mine rigid cage guide, be particularly useful for rigid cage guide vertical shaft hoisting containers such as cage, mining lift car.
Background technology
At present, in most of collieries, to the anti-falling protection of rigid cage guide, KJB type rigid cage guide container falling protector is arranged, its principle of work is to hold rigid cage guide generation cutting force tightly through the wedge shape broaching tool to come for the container that falls braking force to be provided.During normal the lifting, the wedge shape broaching tool is pulled to away from cage guide.When slack rope occurring, under the effect of preloading spring, pull to cage guide and realize the broaching braking through four wedge shape broaching tools.This falling protector can produce king-sized friction force moment in anti-fall braking procedure, its shortcoming is to cause very big braking force and acceleration/accel, and the braking force of constant size can not be provided for the container that falls, thereby causes life danger for the personnel in the lifting container.
Summary of the invention
