Description
Technical field
The utility model relates to transport vehicle, especially relate to a kind of be used under the coal mine with other mine at the mine haulage gear safety catch of leaning angle less than 30 ° tunnel traction mine car.
Background technology
At present, the safety catch of existing haulage gear is to be formed by base, brake control lever, brake shoes, jaw, pull bar, joint, push rod, hydraulic driver (180 type) combine and assemble.Under the normal circumstances, when winch was worked, hydraulic driver energising work meeting was opened safety catch; When sudden power occurring or when needing emergency braking, the hydraulic brake outage, safety catch will be closed and produces a lock torque; Make brake shoes check capstan drum, thereby capstan drum is stopped operating, press safety verification codes and standards and the coal safety range request of AQ1030-2007 colliery with haulage gear; The lock torque of safety catch should be 2.5 times of specified statical moment at least; But 2.5 times of the lock torque out of reach standard-required of general safety catch are at most 1.1～1.3 times through test, and hydraulic brake is the load spring type; Because spring has specified work life; Have the danger of losing efficacy, the safety catch of therefore existing haulage gear does not have due safety guard-safeguard effect in the winch use, have great potential safety hazard.
Summary of the invention
The purpose of the utility model is to provide a kind of requirement that can make lock torque can reach standard and coal safety journey to eliminate the mine haulage gear safety catch of danger that the expection of load spring was lost efficacy, safe, long service life again.
The purpose of the utility model is achieved in that
A kind of mine haulage gear safety catch; Comprise preceding base, Front brake piece, preceding brake control lever, front tab, top rod, rear base, back brake control lever, back brake shoes, rear tab, jaw and hydraulic driver; The bottom of the bottom of preceding brake control lever and back brake control lever is hinged on respectively on preceding base and the rear base; Before Front brake piece and the back brake shoes of placing, be used for checking capstan drum relatively is separately fixed on brake control lever and the back brake control lever; The top of the top of brake control lever and back brake control lever before the rear end of the front-end and back-end joint of front tab is hinged on respectively; Top rod is movably arranged between the front end of rear end and rear tab of front tab, and the front end of jaw is hinged on the top of back brake control lever, and the bottom of hydraulic driver is hinged on the hydraulic bracket; Characteristic is: the front end of connecting plate is hinged on the top of back brake control lever, the below of jaw; The top of weight pull bar is hinged on the rear end of connecting plate, is fixed with pallet in the bottom of weight pull bar through the pallet nut, on pallet, is stacked with some and snaps in the weight in the weight pull bar through the weight breach; The top of last end junction is hinged on the rear end of jaw; The top of connecting plate two-thread screw is installed in the bottom of end junction through the upper end collar nut; The bottom of connecting plate two-thread screw is fixed together through connecting plate nut and connecting plate, and the top of the push rod of hydraulic driver is hinged on the back of the middle part of connecting plate, connecting plate two-thread screw.
Be provided with in the weight indentation, there of weight and be used for the blocking weight breach, prevent the bearing pin that weight comes off from the weight pull bar.
The utility model is to set up a connecting plate on the back brake control lever of hydraulic driver one side in the safety catch of traditional haulage gear; The push rod of connecting plate with connecting plate two-thread screw and hydraulic driver is connected; Add some weights in the rear end of connecting rod then, the total weight of some weights is come out by the required Calculating Torque during Rotary of lock torque, for making safety catch ability normal operation; The model of hydraulic driver adds greatly 320 types and not on-load spring, and promptly this safety catch is a weight hammer type.When the needs emergency braking, the hydraulic driver outage, weight falls; Make connecting rod move backward, preceding brake control lever end of pull bar and back brake control lever motion backward together promote Front brake piece and back brake shoes together to middle intercropping move toward one another; Safety catch is closed; Produce a lock torque, the Front brake piece is checked the reel of haulage gear jointly with the back brake shoes, thereby the reel of haulage gear is stopped operating.Detect through national testing agency; The lock torque of this safety catch can reach the requirement of 2.5 times of specified statical moments of standard-required fully; Can play due safety guard-safeguard to this haulage gear; And weight hammer type braking replaced the load spring, do not have the danger of inefficacy, improved safety.Therefore, the utlity model has the advantage that danger that the expection of load spring lost efficacy, safe, long service life have been eliminated in the requirement that can make lock torque can reach standard and coal safety journey again.
