Description
Affiliated field
The invention belongs to marshaling yard rolling stock braking technology field.Relate to rolling stock brake equipment on Railways Stations field wire.
Background technology
At present, to resting on railway locomotive or the vehicle (row or group) in the places such as maintenance thread, loading and unloading track, high hillside fields section, private siding, mostly still adopt original anti-slip method, these methods mainly contain: 1, by the little reservoir pressurize braking of vehicle self-carrying; 2, horizontal sleeper in orbit; 3, rim brake or iron (wood) footwear etc.These methods rely on people's technical ability, physical efficiency, eyesight and working sense of responsibility, are subject to the impact of natural environment simultaneously, have serious potential safety hazard, and a lot of safety misadventures once occurred, and cause heavy losses to national wealth.In marshaling yard to the locomotive or the vehicle that stop on hair line, existing employing original method is carried out anti-slip, also there is the double track of employing bar inner bearing type stopping device to carry out anti-slip or braking, and at marshalling station's line afterbody of shunting, the particularly line afterbody of shunting of the big-and-middle-sized marshalling station such as road network and regionality, almost mostly is at present to adopt inner bearing type parking slide-proof equipment.These equipment, divide and mainly contain by its principle of work: pneumatic type, hydraulic-driven, four kinds of hydraulic pressure remission form and screw rod drivens, wherein hydraulic pressure remission form and hydraulic-driven are mainly used in marshalling station's line afterbody of shunting vehicle are carried out to anti-slip braking, hydraulic pressure remission form and hydraulic-driven, need the pressurize of hydraulic efficiency pressure system long period to realize change or the maintenance of parking apparatus mode of operation, once leaking appears in hydraulic efficiency pressure system, equipment just loses function, equipment dependability is low, there is potential safety hazard, in addition, hydraulic pressure remission form and hydraulic-driven parking anti-running device, braking rail can not lifting, one's own job machine can not enter the line operation of shunting from compiling tail, in the time that needs locomotive enters operation from compiling tail, must be completed by station rise machine, increase hauling operation cost, affect hauling operation efficiency, pneumatic type parking anti-running device had both been useful on compiles tail vehicle dynamic brake, also be useful on hair line standing vehicle static state anti-slip, because pneumatic type parking anti-running device need to arrange large-scale pump house, lay complicated pipeline, involve great expense, only have at present extremely indivedual stations compiling tail or using to hair line, screw rod driven parking anti-running device had both been useful on the line afterbody of shunting and had braked slipping driving, also be useful on hair line that standing vehicle is carried out to static state is anti-slip, because field working conditions is severe, dust storm dust is larger, lubricated being difficult for of screw mandrel screw guarantees, wearing and tearing are unavoidable, simultaneously, separate unit motor drives multi-filament bar, due to the stressed difference of each brake section, add the elastic deformation of upper screw rod, synchronism can not be guaranteed, cause screw mandrel degree of wear difference, and then affect braking effect, want the equipment state that keeps good, must increase screw mandrel diameter, simultaneously, guarantee the lubricated of screw mandrel, this can increase device fabrication and maintenance cost greatly, increase labor strength, and, screw mandrel is in the middle of station track, once there be car to rest on station track, affect normally carrying out of handling labor, so, it is short that screw rod driven parking anti-running device is difficult for maintenance of life, working service cost is high, impact is promoted the use of.In addition, the dynamic brake of vehicle all exists at general rail yard with static state is anti-slip, so concerning field, station or user, the device type of use is more, will increase maintenance management difficulty, increases working service cost.
Summary of the invention
The object of this invention is to provide the general parking anti-running device of a kind of rail vehicles, it can solve the anti-slip or braking problem of various marshaling yard to hair line and the line afterbody vehicle of shunting effectively.
The object of the invention is to be achieved through the following technical solutions: the general parking anti-running device of a kind of rail vehicles, comprise the bottom girder, braking rail, Hydraulic Station and the electric cabinet that are fixed on rail foot, the bottom girder of brake section is provided with two cross-arms, the two ends of cross-arm are provided with rear linking rod seat, one end of connecting rod is connected with rear linking rod seat by pin, and the other end of connecting rod is connected with the vertical key seat that two ends outside middle connecting plate arrange by pin; Middle connecting plate inner side is provided with horizontal key seat, is connected with one end of waling stripe by pin; The other end of waling stripe is connected with the horizontal key seat that is located at hydraulic actuating cylinder two ends; Cross-arm outside along bottom girder setting is provided with front rod seat, and one end of connecting rod is connected with front rod seat by pin, and the other end of connecting rod is connected with the pivot pin seat of brace side by bearing pin; The outer end side surface of brace is provided with location axle pin, and location axle pin coordinates with the draw-in groove arranging on brace permanent seat; The inner of two braces is equipped with vertical plane, and wherein the vertical plane of one and middle connecting plate are bolted, and between another piece vertical plane and middle connecting plate, is provided with spring; The top of brace permanent seat is provided with a cross-arm, and these cross-arm two ends are provided with the adjustment bolt of tape insulation top.
The insulation top of described adjustment bolt and web of the rail close contact.
Described brake section top is provided with dust guard.
Described brake section arranges more than two.
