Abstract
The utility model discloses a locomotive parking brake control device, which comprises a pressure regulating valve which is communicated with a locomotive air source. The locomotive parking brake control device further comprises a two-way valve, an electrical interlocking cock, a pressure switch and a parking air cylinder. The pressure regulating valve is communicated with the two-way valve through a double-pulse electromagnetic valve. The two-way valve is communicated with a brake cylinder and the electrical interlocking cock of a locomotive. The pressure switch is connected in parallel between the two-way valve and the electrical interlocking cock. The parking air cylinder is connected in parallel between the pressure regulating valve and the double-pulse electromagnetic valve. The parking air cylinder of the locomotive parking brake control device can collect and store main air produced by a main air source during working. When the air source of the locomotive is faulted and a manual release device on the locomotive is failed, by adjusting the double-pulse electromagnetic valve, the parking air cylinder can be used as an air source and the parking brake force can be quickly released.
Description
Technical field
The utility model relates to the Locomotive Brake System field, particularly a kind of locomotive parking brake control setup.
Background technology
The parking brake control setup is one of important component part of locomotive braking system, its function is to control the parking brake power that locomotive braking unit produces, keep railway locomotive to park for a long time on the line or in the storehouse, under the effect of external force such as wind-force, ramp sliding force, guarantee the not unexpected slide car of locomotive.Existing parking brake control setup has only a wind regime, and when locomotive wind regime fault, and the hand relieving device on the locomotive was when losing efficacy, and locomotive can only be in the parking brake state always, can't alleviate parking brake power.
Summary of the invention
Technical problem to be solved in the utility model is, at the prior art deficiency, provides a kind of locomotive parking brake control setup, solve in locomotive wind regime fault, and the hand relieving device on the locomotive loses efficacy and can't alleviate the problem of parking brake power constantly.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of locomotive parking brake control setup, comprise the pressure regulating valve that is communicated with the locomotive wind regime, and also comprise two-way valve, locked cock door, the pressure switch of being electrically connected and park reservoir; Described pressure regulating valve is communicated with described two-way valve by a two pulse electromagnetic valve, and described two-way valve is communicated with the brake cylinder of locomotive, the locked cock door that is electrically connected, the described pressure switch described two-way valve of access in parallel and described being electrically connected between the locked cock door; Described parking between the reservoir described pressure regulating valve of access in parallel and the described two pulse electromagnetic valve.
Compared with prior art, the beneficial effect that the utility model has is: total wind that total wind wind regime produces in the course of the work can be collected and store to the reservoir of parking of the present utility model, when the hand relieving device on locomotive wind regime fault, the locomotive lost efficacy, by regulating the two pulse electromagnetic valve, can alleviate parking brake power fast with parking reservoir as wind regime.
Description of drawings
Fig. 1 is the utility model one example structure schematic diagram.
The specific embodiment
As shown in Figure 1, the utility model one embodiment comprises the pressure regulating valve 1 that is communicated with the locomotive wind regime, also comprises two-way valve 2, the locked cock door 4 that is electrically connected, pressure switch 5 and park reservoir 6; Described pressure regulating valve 1 is communicated with described two-way valve 2 by a two pulse electromagnetic valve 3, described two-way valve 2 is communicated with the brake cylinder 7 of locomotive, the locked cock door 4 that is electrically connected that is fixed on the described parking brake pipe 8, the described pressure switch 5 described two-way valve 2 of access in parallel and described being electrically connected between the locked cock door 4; Described parking between the reservoir 6 described pressure regulating valves of access in parallel and the described two pulse electromagnetic valve.
When locomotive wind regime fault, and when the hand relieving device on the locomotive lost efficacy, press the M/C button on the two pulse electromagnetic valve 3, the wind of parking in the reservoir 6 can enter in the parking brake pipe 8 through two pulse electromagnetic valve, two-way valve, the locked cock door 4 that is electrically connected, and alleviates parking brake power fast.
Claims (1)
