Operable button closes shoulder afterwards；But it is frequently encountered after the completion of cargo the loads and also whole passes of trailer flank
In the case of closing, vehicle just has been started up and starts running, to cause trailer flank, compartment or cargo damage, such as flank or
Cargo, which falls the people for touching, pounding surrounding again or object, will lead to major accident, and there is serious security risks.
The existing wing opens semitrailer brake piping as shown in Figure 1, including supply air line 1 and control piper 2, the gas supply
Pipeline 1 is connect with the air inlet of braking valve for vehicle 3, and the gas outlet of braking valve for vehicle 3 is connect with gas receiver 5, braking valve for vehicle 3
Control mouth is connect with the first emergency relay valve 4；The air inlet of first emergency relay valve 4 is connect with gas receiver, gas outlet second
Emergency relay valve 6 is connect with spring air chamber 7；The brake piping is common " air-cut-off break ", when semitrailer is in halted state,
Compressed air release in spring air chamber 7, realizes braking；If main switch acts, compressed air is through braking valve for vehicle 3, by first
Emergency brake 4 is open-top, into spring air chamber 7, brake release, semitrailer traveling；No matter it follows that the brake piping flank
Whether close, as long as main switch is closed, braking will be released, into transport condition.
Utility model content
The utility model in view of the deficiency of the prior art, provides a kind of wing unlatching semitrailer safety device.
The technical solution that the utility model solves above-mentioned technical problem is as follows：A kind of wing unlatching semitrailer safety device, packet
Brake piping is included, further includes frame and flank, the detection of detectable flank folding condition is equipped between the frame and flank
Switch, the brake piping includes the braking valve for vehicle and the first emergency brake connected by connecting pipe, in the connection
Pipeline, which is equipped with, can control the open or closed calutron of the connecting pipe, and the detection switch is for controlling the electromagnetism
Device action.
Further, the calutron includes solenoid valve, relay and main switch, one end connection control of the main switch
Power supply, the other end connect one end of relay coil, and the other end of relay coil connects the detection switch, the relay
Normally opened contact be connected on main switch and the electromagnetic valve coil.
Further, the frame includes crossbeam and column, and the detection switch is mounted on the crossbeam or column, described
Detection switch may be mounted at crossbeam upper end, can also be mounted on the upper end of column or be mounted on the side of the column by holder
Face.
Further, the detection switch is limit switch.
The utility model has the beneficial effects that：Ensure when flank it is not closed in place when, trailer is in on-position, only when
When flank is closed in place, it can just be released and be braked by control piper, ensure that traffic safety.

Device, 10, limit switch, 11, solenoid valve, 12, flank, 13, crossbeam, 14, column.
Specific implementation mode
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is novel, it is not intended to limit the scope of the utility model.
As shown in Fig. 2-Fig. 3, a kind of wing unlatching semitrailer safety device, including brake piping, further include frame and flank
12, the detection switch of 12 folding condition of detectable flank is equipped between the frame and flank 12, the brake piping includes
The braking valve for vehicle 3 and the first emergency brake 4 connected by connecting pipe is equipped in the connecting pipe described in capable of controlling
The open or closed calutron of connecting pipe, the detection switch is for controlling the calutron action.
The calutron includes solenoid valve 11, relay 9 and main switch 8, one end connection control electricity of the main switch 8
Source, the other end connect one end of 9 coil of relay, and the other end of 9 coil of relay connects the detection switch, the relay
9 normally opened contact is connected on 11 coil of main switch 8 and the solenoid valve.
The frame includes crossbeam 13 and column 14, and the detection switch is mounted on the crossbeam 13.
The detection switch is limit switch 10.
The operation principle of the utility model is：When being not powered on magnetic device, the braking of trailer directly by control piper control braking or
Release braking；For the utility model, main switch powers on, and when flank 12 is closed, relay is connected in limit switch action
9,9 contact of relay is connected to power to the solenoid valve, and solenoid valve 11 acts and be connected to the braking valve for vehicle 3 and first promptly
Connecting pipe between brake valve 4 can send out braking or ring off signal, braking or releasing braking by control piper at this time；Instead
