Abstract
The utility model relates to a hydraulic controlled vehicle stopper which is installed on the tails of railway marshalling yards or other railway lines needing to prevent stopped vehicles from sliding to be used for braking and stopping the vehicles. The utility model mainly comprises brake rails on both sides and a supporting arm which is arranged between the two brake rails and is composed of a rail holder, oil cylinder and spring assemblies and two support arms, wherein the two support arms are respectively hinged with the oil cylinder and spring assemblies and are respectively inserted in directional sliding support seats of the support arms fixed by rail bearings. The utility model has the advantages of high reliability and long service life.
Description
The utility model is a kind ofly to be installed in railway classification yard afterbody etc. other needs on the railway line of parking anti-slip, is used for the hydraulic pressure controlled stopping device that car brakeing is stopped.
At present, the applied hydraulic pressure controlled stopping device of railway interests mainly is to be made of braking rail, supporting arm and hydraulic control device.Wherein supporting arm is by two support arms with place an oil cylinder spring assembly in the middle of two support arms to constitute, and the outer end of two support arms links to each other with holder on two braking rail respectively, places the oil cylinder spring assembly of two support arms centres directly to be connected by bolt.When oil cylinder not only bears axial force during at retarder location, and bear bending force, influenced by it, not only braking effect is not good enough, can reduce the service life of parts such as oil cylinder yet.
At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides and a kind ofly both can guarantee deceleration and stopping performance, can prevent from again to reduce the hydraulic pressure controlled stopping device in service life because of oil cylinder power influence by bending.
The purpose of this utility model is achieved in that it comprises two braking rail and places between two braking rail supporting arm that is made of rail holder, oil cylinder spring assembly, two support arms and the hydraulic control pump of control oil cylinder spring assembly work, it is characterized in that: place the middle oil cylinder spring assembly two ends of two support arms hinged with two support arms respectively, two support arms are inserted into respectively in the directed sliding feet of the support arm of fixing with sleeper.
The utility model has the advantages that: change into directly being connected of two support arms of former stopping device and oil cylinder spring assembly hinged, make it when braking mode, to prevent that the oil cylinder spring assembly from producing bending force, thereby improve service life, it is spacing to utilize the directed sliding feet of support arm that support arm is carried out, and can guarantee the reliability of braking.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is the supporting arm structure scheme drawing.
By accompanying drawing as can be known, the utility model is mainly by two braking rail 1 with place supporting arm 2 and hydraulic control pump 3 between two braking rail to constitute, wherein supporting arm 2 is made of the directed sliding feet 2.4 of two support arms 2.1 that are symmetrically arranged, middle bonded assembly oil cylinder spring assembly 2.2, the rail holder 2.3 that is symmetrically arranged and support arm, two support arms 2.1 are hinged with oil cylinder spring assembly 2.2 respectively, and two support arms 2.1 are inserted into respectively among the rail holder 2.3 that is connected with the fixing directed sliding feet 2.4 of support arm of sleeper 4 with rail 5.Hydraulic control pump 3 is identical with hydraulic pressure, automatically controlled structure in the existing controlled stopping device, so do not provide in the accompanying drawings.
This hydraulic pressure controlled stopping device normality is a retarder location, relies on the spring pressure in the oil cylinder spring assembly to make the supporting arm elongation, promotes braking rail to braking mode, by the braking rail friction face is exerted pressure in the wheel inboard of skating vehicle, promotes car brakeing to stop.At this moment, the oil cylinder off-load of hydraulic efficiency pressure system.
When hydraulic efficiency pressure system to chamber, the oil cylinder of oil cylinder spring assembly 2.2 left side during for high pressure oil, in-oil cylinder piston is moved to the left, length of spring compressed, supporting arm 2 shortens, two braking rail 1 are left the wheel medial surface, vehicle can pass through.
