Abstract
The invention discloses an urban rail vehicle braking cut-off cock device which comprises two electrified contact cut-off cocks and pipelines. The pipelines are fixed on a vehicle body bottom frame structure below a floor through pipe clamps. One end of each electrified contact cut-off cock is communicated with a common pipeline through a union tee. The other end of each electrified contact cut-off cock is connected with a special pipeline thereof through a loose-joint elbow. A sealing module is arranged at a floor mounting hole. An operation rod of each cut-off cock penetrates through the sealing module and extends into a cock box on the floor. The roots of the operation rods and the tops, placed in the cock box, of the operation rods are provided with handles respectively. The structure is compact, operation is convenient, sealing and dustproof effects are good, and the performance of a braking system is guaranteed.
Description
Technical field
The present invention relates to a kind of city rail vehicle braking excision cock device, belong to city rail vehicle manufacturing technology field.
Background technology
In urban rail vehicle brake system, each bogie truck for vehicle is equipped with a set of live contact braking excision cock, in the situations such as braking system faults and maintenance, rescue, test, can excise and recovery operation the air-making power of corresponding bogie truck, and show its state of screen display at TCMS, so that driver judges.The prior art that accompanying drawing 1 provides, under the cushion frame that the two cover braking excision cocks often saving car are arranged in above the brake unit of vehicle rear and front end, by pre-buried pipe sleeve on vehicle body bottom frame 3, adopt threaded line pipe 4, floor underframe for vehicle is run through in the in-built plate of headwall, by elbow 5, snap ring prepackage pipeline 6, turnable elbow 7, to be connected to and under by live contact braking excision, cock 8 is arranged on seat underframe, and adopt same connection mode to lead back under car on brake unit, by installing locking corrosion-resistant steel casing 1 on seat underframe, this part pipeline is covered in casing, during use, case lid can be opened, clamp seat is welded with in casing, for installing single pipe clamp 2, fix for pipeline.There is following problem in this kind of scheme:
1. threaded line pipe 4 is through after built-in pipe 3, carries out encapsulation process with sealant, complex operation and exclusion seal poor effect.
2., when threaded line pipe 4 is connected with elbow 5, screw thread place, two ends needs to be wound around sealing cord, easily enters in pipeline owing to being wound around the improper or fastening sealing cord that excessively causes, thus enters in brake equipment and affect brake system performance.
3. because threaded line pipe 4 runs through floor underframe for vehicle, cannot be fixed in headwall inside, easily make pipeline produce and loosen, thus cause pipeline to reveal.
4. arrange respectively before and after braking excision cock, structure wastes installing space, application adds the operating time, and the operation that cannot realize under car cock, make troubles to driver and service personnel operation, in addition, two cover cocks need to install respectively under its car upper part covers on seat support by corrosion-resistant steel casing, have not only added cost, have affected attractive in appearance but also make troubles to Assembling.
Summary of the invention
Object of the present invention overcomes the deficiency of above-mentioned prior art exactly, provides a kind of city rail vehicle to brake excision cock device.
The object of the present invention is achieved like this: a kind of city rail vehicle braking excision cock device, comprise two live contact cut out cocks and pipeline, it is characterized in that described each pipeline is fixed in the vehicle body bottom frame structure below floor by pipe clamp, one end of described each live contact cut out cock is respectively by union tee and shared pipeline connection, the other end is communicated with respective dedicated line respectively by Loose joint bend, mounting hole place, floor is provided with seal modules, the control lever of described cut out cock reaches in the cock case that is fixed on floor through seal modules, the root of control lever and the top being positioned at cock case thereof are respectively equipped with handle.
In order to better realize object of the present invention, be subdivision rubber block structure in the housing of described seal modules.
In order to better realize object of the present invention, two handles up and down on described same control lever adopt opposite sense, along an inverse set-up mode.
Technical scheme of the present invention, combinationally using of loose-joint collar joint and device for excising, make the excision cock apparatus module centralized arrangement often saving vehicle, compact conformation, reduces installing space.The setting of dual-handle, makes onboard or all can operate device under car.At mounting hole place, floor application seal modules, improve sealing and dustproof effect.Eliminate the threaded passage of original design, the sealing cord avoiding threaded line pipe winding may enter the hidden danger of pipeline, and then guarantees the performance of brake system.

Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Referring to accompanying drawing 3 to 5, the city rail vehicle braking excision cock device of the present embodiment, comprise two live contact cut out cocks 8 and pipeline 21, 22, described each pipeline is fixed in the vehicle body bottom frame structure below floor 10 by pipe clamp 20, one end of described each live contact cut out cock 8 is communicated with common line 22 respectively by union tee 14, the other end is communicated with respective dedicated line 21 respectively by Loose joint bend 18, mounting hole place, floor is provided with seal modules 15, the control lever 16 of described cut out cock 8 reaches in the cock case 1 that is fixed on floor 10 through seal modules 15, the root of control lever 16 and the top being positioned at cock case thereof are respectively equipped with lower handle 17 and upper handle 9.Be subdivision rubber block structure in the housing of described seal modules 15.
