Description
Technical field
The utility model relates to a kind of new type speed reducer, stopping device, is used for the car retardation at train assembly station head one, two, three positions, and the car brakeing of afterbody parking; The brake snub or the stopping brake that also can be used for large-scale industrial enterprise vehicle.
Background technology
Existing retarder (stopping device) mainly contains pneumatic retarder, electric speed reducer (it is slow to be commonly called as electricity) and electric liquid type speed reducer etc., they are concluded to be divided into two classes, one class is to make the retarder of basic foundation, and this class retarder often will be equipped with the gas station or supply its running with multiple electric motors.Another kind of retarder is the interior side brake of machinery or fluid pressure type.There is following shortcoming in this two classes retarder: 1, to do concrete foundation, change basic sleeper, and time-consuming.2, will build special supply station, or use the multiple electric motors power supply, disposable input is excessive, and wastes energy.3, cost of product is excessive, easily hundreds of thousands of yuan.4, inboard formula friction face is too little, and braking force is not enough.5, relatively more difficult to the brake snub of thin wheel car, cause the speed of this class wheel uncontrollable.
Summary of the invention
The purpose of this utility model just provides a kind of new type speed reducer, stopping device, does concrete foundation and changes basic sleeper and cause time-consuming to solve needs that prior art exists; Need build special supply station, or use the multiple electric motors power supply, disposable input is excessive, and wastes energy; Cost of product is excessive, easily hundreds of thousands of yuan; Inboard formula friction face is too little, and braking force is not enough; Brake snub to thin wheel car is relatively more difficult, causes the uncontrollable problem of the speed of this class wheel.
The technical solution of the utility model is: comprise inboard braking rail, braking rail chair, interior extending cylinder and support beam, support beam laterally is loaded on the downside of railway stock rail, two inboard braking rail are positioned the inboard, top of two stock rails respectively by a braking rail chair, the braking rail chair is slidingly connected at that support beam is horizontal to be gone up and be connected with expansion link one end that laterally is installed in an interior extending cylinder on the support beam respectively.The outside of described two stock rails be provided with outside hung brake rail, braking rail chair and outside flexible fluid cylinder, the outside hung brake rail is relative with described inboard braking rail and is connected with an end that laterally is installed in the outer flexible fluid cylinder of described support beam on horizontal by the braking rail chair, the other end of the fluid cylinder that stretches outward with support that beam is horizontal captives joint.
Described inboard braking rail is longer than described outside hung brake rail at direction one end of sending a car, the part that is prolonged be furnished with equally described in extending cylinder and support beam.
The utlity model has following advantage:
1, need not do the basis, be directly installed on the stock rail time and labour saving; Simple in structure.
2, need not build supply station, reduce investment outlay.
3, utilize the ease slide kinetic-energy braking of vehicle self, energy savings.
4, carry out the mechanical classification braking, wheel is longer than outside hung brake just entering inboard braking rail
When the interval of rail is braked, owing to have only interior siding track and wheel to produce friction, therefore friction force is less, after treating that car speed lowers, wheel is subjected to the friction of inside and outside both sides braking rail simultaneously in the interval of braking rail 1,4, friction force increases substantially, and so both can reach good braking effect, can prevent " climbing wheel " phenomenon that occurs when light overall height speed is braked again.Can adjust according to the distance between the internal outside hung brake rail of particular case of field, station or station track during use.
5, owing to adopt the braking of hydraulic pressure medial and lateral, thin wheel car had good braking effect.
Simultaneously can be according to a station different types of vehicle needs in each station track, the size of regulator solution pressing system power, thereby the requirement of field, comprehensive satisfied station.
Description of drawings
Fig. 1 is a horizontal cross-sectional schematic of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises inboard braking rail 1, braking rail chair 2, interior extending cylinder 3 and support beam 4.Support beam 4 laterally is loaded on the downside of railway stock rail 5, two inboard braking rail 1 are positioned the inboard, top of two stock rails 5 respectively by a braking rail chair 2, braking rail chair 2 be slidingly connected on the support beam horizontal stroke 4 and respectively with laterally be installed in support beam 4 on expansion link one end of an interior extending cylinder 3 is connected the same relatively axle mounting of cylinder body one end of each interior extending cylinder 3.The outside of described two stock rails 5 be provided with outside hung brake rail 6, braking rail chair 7 and outside flexible fluid cylinder 8, outside hung brake rail 6 is relative with described inboard braking rail 1, and is connected with cylinder body one end of outer flexible fluid cylinder 8 on laterally being installed in described support beam horizontal stroke 4 (extending to the outside of stock rail 5) by braking rail chair 7, outward expansion link one end of flexible fluid cylinder with support beam horizontal stroke 4 and captive joint.
Described inboard braking rail 1 is longer than described outside hung brake rail 6 at direction one end of sending a car, the part that is prolonged be furnished with equally described in extending cylinder 3 and support beam 4.
Principle of work of the present utility model is as follows:
Glancing impact, under the effect of interior extending cylinder 3 and the outer fluid cylinder 8 that stretches, two inboard braking rail 1 are side shifting outside two sides respectively, makes reducing apart from t between the two; Two outside hung brake rail 6 inboard contractions from two laterals respectively, also make and reduce apart from t, when humping of cars when contacting with braking rail, the motion energy that utilizes vehicle self is by the pressure oil in the braking rail extrusion oil cylinder, make it produce antagonistic force, thereby two faces in medial and lateral of braking rail and wheel are rubbed, produce friction force, reach the purpose of slowing down or braking.
In outside braking rail 1 and 6 length difference L1, can be (in the scope of L0＞L1) at 0～L0
Adjust arbitrarily (not having this situation of outside hung brake rail when containing LI=L0).Wheel is when entering the L1 interval and be braked, owing to have only interior siding track and wheel to produce friction, therefore friction force is less, after treating that car speed lowers, wheel is subjected to the friction of inside and outside both sides braking rail simultaneously in the interval of braking rail 1,4, friction force increases substantially, and so both can reach good braking effect, can prevent " climbing wheel " phenomenon that occurs when light overall height speed is braked again.Can adjust according to the distance between the internal outside hung brake rail of particular case of field, station or station track during use.
