Description
Technical field
The utility model belongs to the railway transportation technical field, particularly yard trim end stop device.
Background technology
At present; The used parking anti-slip device of each marshaling yard marshalling yard afterbody; Mainly contain hydraulic drive type and hydraulic pressure and alleviate two kinds of formulas, hydraulic drive type relies on oil cylinder working-pressure and keeps braking rail to vehicles whose braking forces, and hydraulic pressure alleviation formula is to rely on the further compression brake spring of oil cylinder to realize alleviating.This just needs above-mentioned two types of stopping devicees to keep hydraulic system pressure constant in a long time, or guarantees that the system pressure changing value is controlled in the allowed band within a certain period of time.Yet, under the on-the-spot this rugged environment of railway, any liquid (gas) pressing system; After using a period of time, leakage of oil (gas) phenomenon unavoidably can appear, particularly under high-pressure situations; Be difficult to keep constant pressure for a long time, its major cause is: (1) these two types of stopping device oil cylinder vertical braking rails arrange, and are parallel with the piston rod movement direction and do not pass through the oil cylinder center from the application force of braking rail; Piston rod is produced additional bending moment, cause the leakage of oil of piston eccentric wear; (2) some group oil cylinders are connected each other, as long as place leakage of oil, whole hydraulic efficiency pressure system is not easy to realize long-time pressurize with regard to decompression, influences the stability and the reliability of stopping device mode of operation, has potential safety hazard.
The utility model content
The purpose of the utility model provides a kind of simple in structure, and dependable performance is easy for installation, safeguards railway classification yard trim end parking anti-slip device easily.It is applicable to various marshaling yard marshalling yard afterbody vehicle anti-skid or braking.
The utility model solves its technical matters, and the technical scheme that is adopted is: a kind of hydraulic parking anti-skid device comprises braking rail, braking joint, oil cylinder and Hydraulic Station; It is characterized in that: braking rail is fixed on the braking joint through tie bolt, and the braking joint is fixed on the stock rail, and every group of braking joint is provided with brace; Brace is arranged in the two ends of braking joint; Brace links to each other through the braking rail tie bolt with braking rail, and brace top is provided with braking rail spacing adjustable bolt, and the bottom is connected with the brace seat through pin-and-hole; The brace seat is fixed on the bottom girder, and the brace base part seat drops on the guide rail; Retarding spring is installed between brace and the retarding spring Internal baffle; The retarding spring Internal baffle is connected with brace through the retarding spring tie bolt; The retarding spring Internal baffle is located on the guide rail on bottom girder top; Oil cylinder is arranged in two-system and moves between the spring Internal baffle, and two ends are hinged through connecting rod and retarding spring Internal baffle, and the parallel stock rail of oil cylinder two transmission pin-and-hole line of centres; Hydraulic Station links to each other with oil cylinder through pipeline.
Said retarding spring Internal baffle is provided with the connecting rod key seat.
Said brace is provided with braking rail spacing adjustment tapped bore.
When equipment was in the alleviation position, oil cylinder two end links became " eight " font, and this moment, the oil cylinder piston bar was overhanging, and it is minimum that the distance between two braking rail reaches, and it is worth less than two back gauges, and vehicular traffic is not produced friction; When equipment is in retarder location; Contract in the oil cylinder piston bar, make oil cylinder two end links become " one " font, connecting rod promotes brace through retarding spring Internal baffle and retarding spring and moves outward; Make the distance between two braking rail reach maximum; Its value produces friction greater than two back gauges to vehicular traffic, realizes friction braking.
Compared with prior art, the beneficial effect of the utility model is:
Arrange along stock rail through oil cylinder, utilize piston rod retraction pulling connecting rod, make inner expanding force from braking rail by the mutual balance of the connecting rod of piston rod both sides to " one " font; At this moment; Oil cylinder working-pressure is zero, and piston rod bounces back to initial condition, avoids oil cylinder to receive additional bending moment and causes the piston eccentric wear; And utilize the connecting rod dead point to keep equipment braking mode, reliable and stable.Present technique combines the quick comfort feature of fluid (or gas) action and the lasting stability property of mechanical lever well; Thereby the potential safety hazard of thoroughly avoiding oil (gas) pressing system leakage of oil (gas) and causing braking mode to lose efficacy and bring; Simultaneously, also overcome alleviation and thoroughly do not caused the inaction consumption of locomotive energy and the adverse effect of parking apparatus excessive damage, both saved the locomotive energy; Prolong the service life of equipment, reduced the maintenance cost of equipment again.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
