Abstract
The invention discloses a passive automatic energy-absorbing winch and a brake method thereof. The passive automatic energy-absorbing winch mainly comprises a pulling winch, a pulling steel wire rope, a hoisting steel wire rope, a mine car, a grappling hook device and a buffering and braking system, wherein the pulling steel wire rope is used for pulling the mine car; the buffering and braking system is arranged in a slope guide rail of the mine car; a suspension steel wire rope which is suspended on the pulling steel wire rope is arranged on the grappling hook device. When the mine car quickly falls down due to a breaking accident of the pulling steel wire rope, the grappling hook device quickly falls down under the action of gravity due to the breaking of the pulling steel wire rope, hooks a steel wire rope of a brake system under a track and is further connected with the buffering and braking system through pulleys; the winch is braked and buffered to start working, the brake acceleration of the mine car is controlled in a damping manner, and the mine car can be steadily braked. According to the passive automatic energy-absorbing winch, buffering, energy-absorbing and braking functions can be realized, the safety of the mine car is ensured, a power supply is not needed, parameters can be preset according to loads, energy can be automatically absorbed, and the mine car can be braked. The passive automatic energy-absorbing winch is simple in structure, safe, reliable, and high in practicality.
Description
Technical field
the present invention relates to a kind of winch and braking method thereof, especially a kind of be applicable to inclined shaft without source automatic energy-absorbing winch and braking method thereof.
Background technology
the transportation mode often adopted in the inclined shaft transportation is: settle winch traction mine car transported material above inclined shaft.Due to manual operation and other factors, the disconnected rope of haulage cable often appears, mine car rapidly falls along track, causes casualties and the damage of property.Prevention of sliding-down in inclined well is to be badly in need of the thorny problem solved in coal production always.
Summary of the invention
technical matters: the objective of the invention is to overcome the weak point in prior art, provide a kind of without source automatic energy-absorbing winch gear, by buffering braking system and claw hook device, can occur can to brake rapidly mine car after derailing accident, logical overdamped mode is controlled the braking acceleration of mine car simultaneously, avoid rigid shock, thereby reach the purpose of stable braking mine car.
Technical scheme: of the present invention without source automatic energy-absorbing winch gear, the haulage cable, the claw hook device that comprise traction winch, traction mine car, be provided with buffering braking system in the guide rail of the slope of described mine car, described claw hook device is provided with the steel rope of hanging of hanging on haulage cable, described buffering braking system comprises the braking winch, interval is fixed on the multipair fixed pulley in the guide rail of slope from top to bottom, be provided with two movable pulleys that are connected as a single entity between first pair of fixed pulley and second pair of fixed pulley on slope, on slope, first pair of fixed pulley is provided with middle part and a brake wire that movable pulley is intertwined, brake wire one end is fixed on guide rail, the other end is connected on the braking winch, the interception steel rope one be intertwined with another movable pulley in the middle part of second pair of fixed pulley is provided with, be connected with and be wrapped in respectively other to the interception steel rope two on fixed pulley on interception steel rope one, described claw hook device is hinged on mine car, on the hook curved inner wall in claw hook device, is paying the fire proofing layer.
Use the above device without source automatic energy-absorbing winch braking method, burst accident appears in normal operation when mine car, the disconnected rope of haulage cable, mine car rapidly glides along track, now hoisting wirerope be not subject to the effect of haulage cable, the claw hook device hung falls around bearing pin moment rotation at Action of Gravity Field, in the process that the hook of claw hook device rapidly glides along track at mine car, hang on an interception steel rope in many interception steel ropes, now, under the effect of gravity, movable pulley is subject to tackling the pulling force of steel rope, the buffer rope be wrapped on movable pulley is stressed, control the braking moment of buffer rope by the braking winch, the downslide of interception steel rope under the mine car impact force action, finally make mine car stop, after accident is got rid of, take off hook, control the buffer rope playback by the braking winch.
Beneficial effect: owing to adopting technique scheme, when mine car hurtles down downwards because of the haulage cable rope-broken accident, because the disconnected rope of haulage cable causes the claw hook device gravitate to hurtle down, then can catch on the steel rope of brake system under track, and then be connected with buffering braking system by pulley, braking winch buffering is started working, and with the overdamping mode, controls the mine car braking acceleration, reaches the gradual braking mine car.The present invention can play buffering, energy-absorbing, braking, assurance Safety for mine car winch gear its without power supply source, and can thoroughly do away with the load preliminary setting parameter, realize automatic energy-absorbing braking mine car.It is simple in structure, safe and reliable, practical.
