Abstract

The utility model discloses a mechanical overspeed-vehicle capturing device. The mechanical overspeed-vehicle capturing device consists of two large parts, namely a vehicle stopping part and a controlling part, wherein the vehicle stopping part is a hook of 90 DEG, the hook is arranged on a small dumping tray, and the controlling part is a swinging rod which is arranged on a lifting plate and rotates on site; an angle of the hook of the small dumping tray of the vehicle stopping part is designed to be 85 DEG; and the swinging rod of the controlling part slides up and down so that a sliding component capable of sliding in a reciprocated manner is arranged on the lifting plate, and the swinging rod is arranged on the sliding component. According to the mechanical overspeed-vehicle capturing device, the swinging rod can automatically slide upwards along with the sliding component when a vehicle passes so as to avoid that the lifting of the vehicle is blocked, and the swinging rod automatically returns a design position under the action of gravity so as to avoid striking the small dumping tray; the angle of the hook is small so that a mine car is avoided sliding away; and therefore, the operation reliability of a large-inclination-angle track overspeed-vehicle capturing device is improved, the lifting regular order of tracks is effectively ensured, and the lifting efficiency of the tracks and the safety of the construction are improved.

Description

The mechanical overspeed stop

Technical field

The utility model relates to the conveying track of going down the hill on the mine, relates in particular to the derail avoidance facility that conveying track uses.

Background technology

All be provided with the mechanical overspeed stop on go down the hill conveying track in the mine at present, when mine car hypervelocity get out of hand in order to mine car is blocked.Existing mechanical overspeed stop is comprised of the part of keeping off a car, control part two large divisions, and the part of wherein keeping off a car is to be provided with 90 ° hook little turning over, and control part is to be provided with the fork that rotate in the original place at hanging scaffold.Use fashion to play a role at the common track of going down the hill, there are the following problems in the track of going down the hill at high spud angle uses: the one, and hook angle vertical configuration, mine car is easily slippage on high spud angle is gone down the hill track; The 2nd, fork is upwards passed along with carrying on the vehicle continuously, when vehicle by after return rapidly, impact little turning over larger strength when returning, after little the impacting several times of turning over continuously, the part of keeping off a car can landed unconsciously, thereby loses the effect of keeping off a car, and fork easily withstands and carries car, on cause fork flexural deformation when carrying loaded vehicle, on carry light Che Shiyi vehicle pushed away, affect lifting track safety.Therefore be sought after overspeed vehicle arrester is improved.

Summary of the invention

The utility model is that existing overspeed vehicle arrester is improved, and a kind of mechanical overspeed stop is provided, to solve the problems referred to above that exist in high spud angle is gone down the hill the track use.

Technical scheme is, a kind of mechanical overspeed stop, and it is comprised of keep off a car part and control part two large divisions; The part of wherein keeping off a car is to be provided with 90 ° hook little turning over, and control part is to be provided with the fork that rotate in the original place at hanging scaffold; It is characterized in that, the hook angle design on little the turning over of the part of keeping off a car is 85 °; The fork of control part is sliding up and down, namely establishes a sliding component that slidably reciprocates at hanging scaffold, and fork is installed on the sliding component.

The utility model has the advantages that: when vehicle by the time, fork can be automatically with the sliding component slippage that makes progress, avoid withstanding and carry vehicle, fork falls back to design attitude voluntarily under Action of Gravity Field, avoid impacting little turning over; The hook angle is little avoids the mine car slippage; Thereby improved the reliability of high spud angle track overspeed vehicle arrester work, effective guarantee the normal order of lifting track, improved the safety of lifting track efficient and construction.
