Summary of the invention
In order to solve the problems referred to above, this utility model provides a kind of locomotive braking system auxiliary parking device, this auxiliary parking device is when carrying out arranging without fire to locomotive, it is to avoid open the step of average tube cock under operator to car, only need to carry out onboard being simply provided.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of locomotive braking system auxiliary parking device, including the three linkage cocks with three air inlets and three gas outlets, three air inlets of three linkage cocks are connected to air main interface, list interface tube and average interface tube, the two of which gas outlet of three linkage cocks is all connected with check valve, and the other end of these two check valves in parallel connects parks interface tube；Last gas outlet of three linkage cocks leads directly to air.
As further optimization of the present utility model, three linkage cocks are two position three-way valve.
As further optimization of the present utility model, being provided with integrated air board between three air inlets of three linkage cocks and air main interface, train pipe interface and average interface tube, air inlet is connected by the gas circuit on integrated air board with above three interface.
As further optimization of the present utility model, two check valves and park and be provided with integrated air board between interface tube, are converged by two check valve effluent airs gas circuit on integrated air board and are connected to park interface tube.
As further optimization of the present utility model, at the gas outlet that three linkage cocks communicate with air, it is provided with integrated air board, will be communicated with air by the gas of this gas outlet gas circuit on integrated air board.
As further optimization of the present utility model, it is provided with integrated air board at three air inlets of three linkage cocks and three gas outlets, to realize three linkage cocks and other interfaces or the connection of air.
Compared with prior art, advantage of the present utility model and having the active effect that
Locomotive braking system of the present utility model auxiliary parking device, use three linkage cocks, locomotive operation personnel are effectively avoided to go to open the trouble of four average tube to headstock two ends, only need to open position without three linkage cocks being placed in during thermal transfer car, eliminate a step, save more time, more simple and convenient.

Detailed description of the invention
Below, by exemplary embodiment, this utility model is specifically described.It should be appreciated, however, that in the case of not being further discussed below, element, structure and features in an embodiment can also be advantageously incorporated in other embodiments.
See Fig. 2, be the schematic diagram of locomotive braking system auxiliary parking device in this utility model.As shown in Figure 2, locomotive braking system of the present utility model auxiliary parking device includes the three linkage cocks 3 with three air inlets and three gas outlets, this three linkages preferred two position three-way valve of cock 3, three air inlets of three linkage cocks 3 are connected to air main interface, list interface tube and average interface tube, the two of which gas outlet of three linkage cocks 3 is all connected with check valve 2, and the other end of these two check valves 2 in parallel connects parks interface tube；Last gas outlet of three linkage cocks 3 leads directly to air.
By above-mentioned parking device, after the air main of locomotive, train pipe and average tube being docked with above-mentioned the corresponding interface, just can realize parking the purpose of residual gas in emptying average tube simultaneously without alleviating during thermal transfer car.
In conjunction with Fig. 3, it it is the structural representation of three linkage cocks in this utility model.As shown in Figures 2 and 3, being provided with integrated air board 4 between three air inlets and air main interface, train pipe interface and the average interface tube of above-mentioned three linkage cocks 3, air inlet is connected by the gas circuit on integrated air board 4 with above three interface.
It addition, two check valves 2 and park and may also set up integrated air board 4 between interface tube, converged by two check valve 2 effluent airs gas circuit on integrated air board 4 and be connected to park interface tube.
Or, it is provided with integrated air board 4 at three gas outlets that communicate with air of linkage cocks 3, will be communicated with air by the gas of this gas outlet gas circuit on integrated air board.
As a kind of optimum embodiment, it is provided with integrated air board 4 at three air inlets of three linkage cocks 3 and three gas outlets, to realize three linkage cocks and other interfaces or the connection of air.
Air inlet or gas outlet are communicated with each interface or air by the gas circuit on integrated air board and are advantageous in that, are more conducive to converge gas.
Below, in conjunction with use of the present utility model, further illustrate the beneficial effects of the utility model:
When locomotive normally works, three linkage cocks are placed in close stance, now air main seam can turn on, it is introduced to park interface tube output from air main interface by total for locomotive wind, realize locomotive parks control, and because other two passages of three linkage cocks are closed, the gas in train pipe cannot air draft in cannot be introduced into parking module and average tube.
When connecting the master control locomotive train pipe with fireless locomotive and carrying out without thermal transfer car, three linkage cocks of fireless locomotive are placed in and open position, the path now only having air main seam is truncated, in this case, owing to one of them air inlet of three linkage cocks is connected with train pipe interface, then the wind of train pipe can be introduced parking device, thus reach to alleviate the purpose parked, meanwhile, after one of them gas outlet of three linkage cocks communicates with air, directly the residual gas in fireless locomotive average tube can be discharged, prevent from causing checking cylinder not alleviate.
Utilize locomotive braking system auxiliary parking device in this utility model, locomotive operation personnel can be avoided to headstock two ends to go to open the trouble of four average tube, only need to open position without three linkage cocks being placed in during thermal transfer car, eliminate a step, save more time.
