Abstract
The utility model discloses a hydraulic drive numerical control vehicle retarder. The vehicle retarder is characterized in that roller supports are fixed on a rail bearing plate; elastic supporting wheels are fixed on the roller supports; a following supporting plate is arranged between a roller and a stock rail; a work cylinder supporting seat and a brake plate sliding table are fixed on the following supporting plate; a front work oil cylinder and a rear work oil cylinder form a double telescopic structural oil cylinder which is fixed on the work cylinder supporting seat; a brake clamp plate sliding bracket is clamped on the brake plate sliding table; a brake clamp plate and the brake clamp plate sliding bracket are integrally fastened by high-strength bolts and are connected with a piston of the front work oil cylinder through an adjustable thrust screw; and after an opening of the clamp plate is adjusted, a lock nut is fastened, and the front work oil cylinder and the brake clamp plate are integrated. The vehicle retarder has the advantages that the noise can be reduced greatly. The high-temperature melting damage between the clamp plate and a wheel can be avoided, and the current production and operation environment of the national vehicle classification yard, and the safe operation reliability are improved.
Description
Technical field
The utility model relates to the rolling stock equipment technical field, particularly a kind of numerical control car retarder that surges.
Background technology
Car retarder is that the train marshalling yard is used for the important wayside equipment to skating vehicle implementation goal braking deceleration.The car retarder that present each marshalling yard is installed, mostly be take air as steering maneuver, link transmission, mechanical lever gravity type boat davit braking deceleration, this equipment exists structural defect in using on the spot, the shortcoming that namely noise is high, the brake snub control accuracy is low and the improper damage rate of parts is high.
Summary of the invention
The purpose of this utility model provides a kind of take hydraulic oil as working medium, vehicle gravity is delivered to operating cylinder by hydraulic oil pump, be converted to the thrust that acts on the wheel braking clamping plate, thereby realize the numerical control car retarder that surges to the vehicle implementation goal brake snub in the motion.
The utility model is to realize like this, it comprises servo-actuated back plate, the slipper slide unit, the sensor of jumping onto the tracks, pull back spring, brake clamping plate, the brake clamping plate slipper bracket, front clutch release slave cylinder, front slave cylinder piston, rear clutch release slave cylinder, the clutch release slave cylinder supporting seat, capable of regulating thrust screw rod, the gravity oil pump, the movable head postioning abutment, the elastic support wheel, roller support, Hydraulic Station, supercharging subtracts ripple device and energy storage canister, it is characterized in that roller support is fixed on the concrete slab sleeper, the elastic support wheel is fixed on the roller support, servo-actuated back plate floats and is arranged between roller and the stock rail, the clutch release slave cylinder supporting base, the slipper slide unit is fixed on the servo-actuated back plate, front operating cylinder and rear operating cylinder consist of two stretching structure oil cylinders and are fixed on the clutch release slave cylinder supporting base, the brake clamping plate slipper bracket is stuck on the servo-actuated back plate, brake clamping plate is fastened on one by high strength bolt and brake clamping plate slipper bracket, be connected with the piston of front operating cylinder by capable of regulating thrust screw rod, fastening lock jack panel after adjusting the clamping plate opening consists of front operating cylinder and brake clamping plate whole.
The utility model has the advantages that, during the hydraulic retarder braking, it is horizontal motion that brake clamping plate is pushed wheel to, acts on wheel unit area pressure even.So noise can significantly reduce.High temperature melting can not occur between clamping plate and wheel yet hold damage; Hydraulic actuating cylinder braking, alleviate operating distance and be not more than 25mm, move little, quick, the operation of applicable PLC system, what do not have the such vehicle landing of mechanical lever during alleviation can high release.So vehicle can steadily be overflowed with setting speed; The hydraulic numerical control gravity vehicle reducer has the significant performance advantage than pneumatic machine lever gravity vehicle reducer, and it will improve the present production operation environment of China's vehicle marshalling yard and improve the safe operation reliability.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described;
Fig. 1 is the structural representation of numerical control car retarder of surging.
The specific embodiment
As shown in Figure 1, this numerical control car retarder that surges comprises servo-actuated back plate 1, stock rail 2, servo-actuated back plate 3
,Slipper slide unit 4, bolt 5, the sensor 6 of jumping onto the tracks, pull back spring 7, brake clamping plate 8, brake clamping plate slipper bracket 9, jam nut 10, front clutch release slave cylinder 11, front slave cylinder piston 12, rear clutch release slave cylinder 13, clutch release slave cylinder supporting seat 14, capable of regulating thrust screw rod 15, gravity oil pump 16, movable head postioning abutment 17, elastic support wheel 18, roller support 19, Hydraulic Station 20, supercharging subtracts ripple device 21, energy storage canister 22, oil main line road 23 and concrete slab sleeper 24, roller support 19 is fixed on the concrete slab sleeper 24, elastic support wheel 18 is fixed on the roller support 19, servo-actuated back plate 3 floats and is arranged between roller and the stock rail, clutch release slave cylinder supporting base 14, slipper slide unit 4 is fixed on the servo-actuated back plate 17, front operating cylinder 11 and rear operating cylinder 13 consist of two stretching structure oil cylinders and are fixed on the clutch release slave cylinder supporting base 14, brake clamping plate slipper bracket 9 is stuck on the servo-actuated back plate 1, brake clamping plate 8 is fastened on one by high strength bolt and brake clamping plate slipper bracket 9, be connected with the piston of front operating cylinder 11 by capable of regulating thrust screw rod, fastening lock jack panel after adjusting the clamping plate opening, front operating cylinder 11 and brake clamping plate 8 are consisted of whole, its principle of work is; During braking, under the vehicle action of gravitation, operating cylinder 11 before operating cylinder 13 and the promotion after the hydraulic oil of gravity oil pump 16 is extruded and flows into.Put on the brake resistance of wheel by front slave cylinder piston 12, capable of regulating thrust screw rod 15, brake clamping plate slipper bracket 9, brake clamping plate 8.The size variation of its application force equals the variation of car load size.Operating cylinder 11 is under the effect of hydraulic control system before this moment, brake clamping plate 8 pushed away extremely adjusting between two clamping plate of setting brake aperture position.Because front operating cylinder 11 outer rims are pistons of rear operating cylinder 13, so operating cylinder 11 is set the braking aperture position before consisting of, rear operating cylinder 13 applies brake resistance.And strengthen or reduce to put on the resistance of wheel by controlling front operating cylinder 11 hydraulic fluid pressures, realize the aim parameter control to wheel decelerates.
