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
Technical field
The present invention relates to a kind of anti-fall break catching apparatus of permanent braking force and method for mine rigid cage guide, be particularly useful for the rigid cage guide vertical shaft hoisting containers such as cage, mine elevator car.
Background technology
At present, in most of collieries, for the anti-falling protection of rigid cage guide, have KJB type rigid cage guide container falling protector, its principle of work is by wedge shape broaching tool, to hold rigid cage guide tightly to produce cutting force and provide braking force for the container falling.During normal hoisting, wedge shape broaching tool is pulled to away from cage guide.When there is slack rope, by four wedge shape broaching tools, under the effect of preloading spring, pull to cage guide and realize broaching braking.This falling protector can produce king-sized friction force moment in anti-fall braking procedure, and its shortcoming is to cause very large braking force and acceleration/accel, and the braking force of constant size can not be provided for the container falling, thereby causes life danger to the personnel in lifting container.
Summary of the invention
Technical matters: the object of the invention is to overcome deficiency of the prior art, provide a kind of compact conformation, safe and reliable, can keep that constant acceleration/accel slows down, the effective anti-fall break catching apparatus of permanent braking force and method for mine rigid cage guide.
Technical scheme: the anti-fall break catching apparatus of permanent braking force mine for rigid cage guide of the present invention, comprises the anti-fall catching device that is fixed on cage bottom and the break catching apparatus that is fixed on cage two bottom sides; Described anti-fall catching device comprises the main tie being connected with hoisting cable through cage, the lower end of main tie is provided with crossbeam, the both sides of crossbeam are respectively equipped with slide block and the spring being fixed on cage, on each slide block, be hinged with a pair of driving lever, one end of driving lever is hinged on crossbeam through connecting plate, the other end of driving lever is hooked in the bottom of break catching apparatus, and the bottom of driving lever is fixed on spring; Described break catching apparatus comprise be fixed on cage both sides base plate, be bolted on the wedge box on base plate, the sliding wedge that is symmetricly set on the wedge block in wedge box and matches with wedge block, the both sides of wedge block are provided with gib block, between wedge block and sliding wedge, be provided with roller and the fixing retainer of roller, wedge box is provided with the spring bolt being fixed on wedge block, and spring bolt is provided with disk spring.
Described wedge box top is symmetrically welded with two gussets; Described wedge block top offers the wedge block guide groove along guide bolt cross travel, the both sides, front and back of wedge block are respectively provided with two tapped bore that connect gib block, on the wedge block side relative with wedge box, have blind hole, the wedge block skew back face relative with blind hole side offers roller guide groove; One side and the wedge block of described gib block link together through screw, and the opposite side of gib block is stuck in the voussoir guide groove of sliding wedge; On described sliding wedge, a side corresponding with wedge block has the roller guide groove that is parallel to wedge block surface, and the bottom of sliding wedge offers the bar v notch v of driving lever hook.
The anti-fall method of arresting of permanent braking force for mine rigid cage guide of the present invention: when there is disconnected rope, the main tie being connected with hoisting cable declines, under the effect of spring, the overhanging end of driving lever lifts, make sliding wedge along the upwards operation of track of gib block, then contact and push the horizontal braking force of generation with rigid cage guide, in this process, sliding wedge pushes wedge block and moves laterally along guide groove, wedge block compression disk spring; When sliding wedge moves to wedge box top, sliding wedge is stopped rear stop motion by wedge box, the spacing of wedge block and wedge box remains unchanged, disk spring amount of compression between wedge block and wedge box remains unchanged, the pressure that disk spring produces wedge block keeps definite value, thereby the positive pressure between sliding wedge and rigid cage guide keeps definite value; The cage of tenesmus is subject to constant braking force the braking deceleration with constant is slowed down, and is finally arrested on rigid cage guide.
Beneficial effect: compact conformation of the present invention, easy for installation, be applicable to the anti-fall braking of the vertical shaft hoisting containers such as cage, mine elevator car, have and arrest reliably, laterally braking force is constant and adjustable, effectively prevent the feature that foreign material are fallen into, can make container keep constant braking deceleration, overcome the limitation that current rigid cage guide catching device braking deceleration is excessive, brake-force control is difficult, anti-fall braking safety is low, guaranteed staff's safety simultaneously.
