Abstract
The utility model relates to a trailer tire-skidding monitoring device, which is characterized in that a hand valve switch is mounted on a hand brake valve, and a foot valve switch is mounted on a foot brake valve; a pressure sensor I is mounted in a spring cavity pipeline; a pressure sensor II and a pressure sensor III are arranged at a membrane cavity pipeline; the trailer tire-skidding monitoring device is provided with a signal collecting box for receiving the signals of the hand valve switch, the foot valve switch and four paths of pressure sensors; and the trailer tire-skidding monitoring device is provided with a man-machine terminal for receiving the pressure and alarm signals of the signal collecting box. The trailer tire-skidding monitoring device has the beneficial effects that the work state of the trailer brake system can be monitored, the pressure data of the brake pipeline can be detected, and the overheating of tires caused by tire skidding due to a brake fault can be pre-warned to avoid autoignition, and the mounting is simple without the need of changing the original air path pipelines.
Description
Technical field
The utility model relates to a kind of trailer or superimposed trailer drags the tire monitoring and warning.
Background technology
Along with the development of transportation, the container trailer transportation will become the topmost a kind of transportation mode of shipping gradually.Yet the phenomenon of trailer tire spontaneous combustion in the long-distance transport way happens occasionally, its reason mainly is trailer brake system non-normal working when driving, make some or several tires brake in advance to cause and drag tire, tyre temperature will sharply raise and reach the tire burning-point in this process.At this phenomenon, still there is not effective solution at present.
Summary of the invention
The purpose of this utility model provides a kind of trailer and drags the tire monitoring device to remedy the deficiency of prior art.
The utility model for the technical scheme that realizes purpose is: 1, trailer drags the tire monitoring device, it is characterized in that:
A. tractor truck part: the hand brake valve place is equipped with the hand threshold switch, at foot brake valve place installation foot threshold switch;
B. trailer part: pressure sensor one is installed in the spring cavity pipeline; The diaphragm chamber pipeline is equipped with pressure sensor two and pressure sensor three;
C. be provided with the acquisition of signal box, receive hand threshold switch, foot valve switch and 4 road pressure sensor signals; Be provided with man-machine terminal, receive pressure and the alerting signal of acquisition of signal box.
The beneficial effects of the utility model are: the utility model can be monitored the trailer brake system mode of operation, detects the brake-press lead pressure data, and early warning drags tire to cause that tire is overheated, and spontaneous combustion takes place because brake fault causes.Prevent improper braking and produce to drag tire; Install simply, need not to change former car gas path pipe.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Embodiment:
The trailer braking protection valve principle: the trailer service brake is the diaphragm chamber service braking, and braking during standstill then is the spring cavity service braking; Therefore, brake spring lumen road should keep high pressure to make spring compression, diaphragm chamber pipeline should be low pressure or zero-pressure with brake off when driving.When stepping on foot-operated brake, diaphragm chamber should keep high pressure, and diaphragm chamber work realizes braking; And when braking during standstill, lift hand brake valve, get rid of the spring cavity high pressure and make spring reset implement braking.
This device is installed a hand threshold switch 2 respectively at hand brake valve 1 place of tractor truck, a foot valve switch 8 is installed at foot brake valve 9 places, when foot brake valve 9 step on or hand brake valve 1 when lifting hand threshold switch 2 or 8 actions of foot valve switch produce energizing signal.
The trailer part: during spring cavity pipeline setting pressure sensor 4 is gathered, the spring cavity pressure of back axle, diaphragm chamber pipeline setting pressure sensor 3, pressure sensor 5 and pressure sensor 6 are gathered propons, jackshaft and back axle diaphragm chamber pressure respectively.Hand, foot valve switch 2,8 signal and 4 road pressure sensor signals all are input to acquisition of signal box 7.Collecting cassette 7 sends to force value and alerting signal on the man-machine terminal 10 of operator's compartment.In normal driving process, foot brake valve 9 and hand brake valve 1 all are in and lift the position, foot valve switch 8 and hand threshold switch 2 do not produce energizing signal, acquisition of signal box 7 is constantly gathered 4 road pressure sensor signals and double switch signal, when sensor 4 force value were lower than threshold value P1, brake push rod is subjected to action of the spring and unexpected release may cause indivedual tires brakes; Push rod will be subjected to the diaphragm thrust and unexpected the release causes that indivedual tires brake when sensor 3 or sensor 5 or sensor 6 force value are higher than threshold value P2; Give birth to braking and all the other tires when not producing braking when the individual wheels fetal hair, the tire of braking namely produces and drags the tire phenomenon.As long as therefore detecting sensor 4 force value when driving is lower than threshold value P1, pressure sensor 3 or pressure sensor 5 or pressure sensor 6 force value are higher than threshold value P2, all produce alerting signal, and the braking of prompting chaufeur is unusual, needs maintenance.
