Technical field
The utility model relates to a kind of air pressure and detects utensil, more precisely, relates in particular to a kind of utensil that detects at air brakes vehicles.
Background technology
Requirement according to GB7258-" motor vehicle safe operation technical conditions ": rise to 600kPa and do not use under the situation of braking at air pressure, stop air compressor 3min after, the reduction value of its air pressure should be greater than 10kPa.Be under the situation of 600kPa at air pressure, brake pedal is floored, treat to observe 3min after the stable gas pressure, automobile pressure reduction value should be greater than 20kPa, and the air pressure reduction value of truck combination, articulated coach and articulated trolley bus, wheeled tractor transportation unit should be greater than 30kPa.Engine is under 75% rated speed, and the indication air pressure of 4min internal gas pressure table should be started from scratch and be risen to starting air pressure, and fluctuates in the release of 24 hours internal gas pressures.Therefore need carry out the pressure test in each stage to the motor vehicles that adopt air-pressure brake.
The utility model content
The utility model is in order to solve problems of the prior art, provides a kind of air pressure at air brakes vehicles to detect utensil, and it is simple in structure, and is easy to use, can observe effectively that air brakes vehicles boosts, the change procedure of step-down and pressurize.
In order to realize above-mentioned purpose, the technical solution of the utility model is: a kind of air pressure at air brakes vehicles detects utensil, comprise utensil support, two tensimeters are fixedly arranged on the described utensil support, described two manometric instrument connectors are communicated with by flexible pipe and quick connector assembly.
Preferably, described flexible pipe is telescopic corrugated hose.
Preferably, described quick connector assembly comprises with the quick connector of soft pipe connection and is used for and quick connector seat that valve port to be detected cooperates.
Preferably, described utensil support comprises upper and lower symmetry and first support that is solidly installed and second support, described first support and second support include rack body, the two ends of described rack body are connecting plate circular-arc and that cooperate with tensimeter part outside surface, and described tensimeter is assemblied between the connecting plate of the connecting plate of first support and second support.
Preferably, described connecting plate is shell fragment, and described first support and second support install by the bolt at rack body place.
Preferably, also be provided with hook on the described rack body.
Detection utensil of the present utility model, it is simple in structure, is support with the utensil support, can bolt on utensil support or other fixed forms known in the art install two tensimeters, be respectively applied to the air pressure change situation of measuring vehicle front and back wheel, use and convenient.The quick connector assembly comprises with the quick connector of soft pipe connection and is used for and quick connector seat that valve port to be detected cooperates.Select the plinth of appropriate size during measurement, respectively with air drum on plug on the chamber of control front and rear wheel braking or water drain valve install and be connected, plug quick connector again, other mixes for example stopwatch of timing appliance, can detect the numerical value of various states.
Description of drawings
Fig. 1 shows the structural representation that the utility model detects utensil.
Fig. 2 shows the structural representation of utensil support among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
With reference to figure 1, a kind of air pressure at air brakes vehicles of the present utility model detects utensil, comprises utensil support, and two tensimeters 8 are fixedly arranged on the described utensil support, and the instrument connector 4 of described two tensimeters 8 is communicated with by flexible pipe and quick connector assembly.Detection utensil of the present utility model, it is simple in structure, is support with the utensil support, can bolt on utensil support or other fixed forms known in the art install two tensimeters 8, be respectively applied to the air pressure change situation of measuring vehicle front and back wheel, use and convenient.
Fast plug assembly provides one to measure passage easily for this detections utensil, in the time of use, plug or the water drain valve of controlling on itself and the air drum on the chamber that front and rear wheel brakes is connected, and it is existing structure, no longer specifies at this.For example, the preferred quick connector assembly of the utility model comprises with the quick connector 6 of soft pipe connection and is used for and quick connector seat 7 that valve port to be detected cooperates.Select the plinth 7 of appropriate size during measurement, respectively with air drum on plug on the chamber of control front and rear wheel braking or water drain valve install and be connected, plug quick connector 6 again, other mixes for example stopwatch of timing appliance, can detect the numerical value of various states.
Preferably, flexible pipe of the present utility model is telescopic corrugated hose 5, can stretch or the withdrawal flexible pipe according to distance like this.The preferred following structure of utensil support of the present utility model: with reference to figure 2, comprise upper and lower symmetry and first support 30 that is solidly installed and second support 31, described first support 30 and second support 31 include rack body, the two ends of described rack body are connecting plate 9 circular-arc and that cooperate with tensimeter part outside surface, like this, but laterally zygomorphic connecting plate has been formed one and has been held and the space of fixation pressure table, and namely described tensimeter 8 is assemblied between the connecting plate 9 of the connecting plate of first support 30 and second support 31.Connecting plate 9 of the present utility model is preferably shell fragment, and described first support 30 and second support 31 install by the bolt 2 at rack body place.Because the character of shell fragment itself in fastening bolt 2, can make the shell fragment on first support and second support press to manometric surface, thereby tensimeter is fixed.
