Abstract
The utility model belongs to mine haulage equipment, and particularly relates to a double-speed haulage winch safety brake. The lower end of a left brake beam (5) and the lower end of a right brake beam (12) are hinged to the left side and the right side of the upper face of a base (1) respectively, brake shoe blocks (7) are symmetrically arranged on the left brake beam (5) and the right brake beam (12) and are arranged on two sides of a brake wheel (3) respectively, an ejection pull rod base (8) is hinged to the upper end of the left brake beam (5), a hydraulic spring driver (10) is hinged to the upper end of the right brake beam (12), an oil inlet connector (11) is arranged on a driver end cap (10-3) of the hydraulic spring driver (10), the ejection pull rod base (8) is connected with the left end of an ejection pull rod (9), the right end of the ejection pull rod (9) is in contact connection with a plunger (10-1) of the hydraulic spring driver (10), and the plunger (10-1) of the hydraulic spring driver (10) is sleeved with a belleville spring (10-2). The double-speed haulage winch safety brake fundamentally eradicates the potential safety hazard of safety brake failure caused by accidental oil leakage at the connector.
Description
Technical field
The utility model belongs to mine transportation equipment, particularly a kind of double speed haulage gear sure brake.
Background technology
The double speed haulage gear is widely used under coal mine or aerial pickup scheduling marshalling mine car and interdrive delivery mine car and other assistant conveyance work, the hydraulic spring grease cup drg of this sure brake is arranged on the brake wheel top of winch final stage transmission, once come oily joint that leakage of oil occurs, just in time drop on brake wheel, cause sure brake to lose efficacy, lost safety production condition.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of simple in structure, safe and reliable, can meet the double speed haulage gear sure brake of Safety of Coal Mine Production demand.
The technical scheme that the utility model technical solution problem adopts is: double speed haulage gear sure brake comprises pedestal, the bearing mounting, bearing seat, brake axle, brake wheel, left brake beam, right brake beam, the brake shoe piece, the top draw-bar seat, the top pull bar, pipeline, be characterized in that on the pedestal left and right sides links respectively the lower end of left brake beam and right brake beam, on left brake beam and right brake beam, symmetry is equipped with the brake shoe piece, the brake shoe piece is placed in respectively the both sides of brake wheel, the hinged top draw-bar seat in the upper end of left brake beam, the hinged hydraulic spring grease cup actuator in the upper end of right brake beam, the drive side of hydraulic spring grease cup actuator covers a next oily joint is housed, the top draw-bar seat connects the left end of top pull bar, the plunger of the right-hand member contact connecting fluid pressing spring actuator of top pull bar, be set with belleville spring on the plunger of hydraulic spring grease cup actuator.
The beneficial effects of the utility model are: the next oily joint location of double speed haulage gear sure brake is away from brake wheel, fundamentally stopped the potential safety hazard that leak occurrent joint, draining safety arrestment that phenomenon causes was lost efficacy, so just can guarantee that lock torque reaches the requirement of safety regulations in coal mine.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, with embodiment, illustrate.
Fig. 1 is that figure cuts open in double speed haulage gear sure brake structure office.
In figure, the 1-pedestal; 2-bearing mounting; The 3-brake wheel; The 4-bearing seat; The left braking of 5-fine strain of millet; The 6-brake axle; 7-brake shoe piece; 8-top draw-bar seat; 9-top pull bar; 10-hydraulic spring grease cup actuator; The 10-1-plunger; The 10-2-belleville spring; 10-3-actuator end cap; 11-carrys out oily joint; The right brake beam of 12-; The 13-pipeline; The 14-Hydraulic Station.
The specific embodiment
Embodiment, with reference to accompanying drawing 1, above the pedestal 1 of double speed haulage gear sure brake, arranged on left and right sides is hinged respectively the lower end of left brake beam 5 and right brake beam 12, on left brake beam 5 and right brake beam 12 respectively symmetry brake shoe piece 7 is housed, brake shoe piece 7 is placed in respectively the both sides of brake wheel 3, and brake wheel 3 is contained on brake axle 6, and brake axle 6 is contained on the bearing in bearing seat 4, bearing seat 4 is fixed on bearing mounting 2, and bearing mounting 2 is fixed on pedestal 1.The hinged top draw-bar seat 8 in left brake beam 5 upper ends, the hinged hydraulic spring grease cup actuator 10 in the upper end of right brake beam 12, top draw-bar seat 8 connects the left end of top pull bar 9, the plunger 10-1 of the right-hand member contact connecting fluid pressing spring actuator 10 of top connecting rod 9, the upper suit of the plunger 10-1 of hydraulic spring grease cup actuator belleville spring 10-2, the left end of hydraulic spring grease cup actuator 10 is equipped with actuator end cap 10-3, and the upper dress of actuator end cap 10-3 carrys out oily joint 11, comes with pipeline 13, to be communicated with between oily joint 11 and Hydraulic Station 14.
The working process of double speed haulage gear sure brake is: the Oil pump electrical machinery that starts Hydraulic Station 14, the operator passes handgrip, oil pressure raises, the plunger 10-1 of hydraulic spring grease cup actuator 10 stretches out, belleville spring 10-2 compression increases top pull bar 9 total lengths, left brake beam 5 and right brake beam 12 are outwards moved to be realized declutching, when in case of emergency, the operator presses scram button, Hydraulic Station 14 Oil pump electrical machinery outages, the rapid back to zero of oil pressure, belleville spring 10-2 resets, pull bar 9 total lengths in top shorten rapidly, realize brake, reach the safety arrestment purpose.
