Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire testing technology, specifically to a tire internal temperature and pressure measuring device. Background Technology
[0002] In mining operations, many mining companies do not install built-in tire temperature and pressure systems for giant all-steel radial tires due to cost factors. They need to manually measure the tire pressure from the outside and cannot measure the internal temperature. At the same time, the internal temperature of the tire is a very important parameter for the thermal dynamic management of the tire's gas.
[0003] Therefore, it is necessary to measure the internal temperature and pressure of the tire during operation to improve the accuracy of the thermal dynamic management of the gas inside the tire. Utility Model Content
[0004] The purpose of this invention is to solve the problem that existing giant all-steel radial tires do not have a built-in tire temperature and pressure system, which lacks the ability to detect the internal temperature and pressure of the tire and affects the tire's service life.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A tire internal temperature and pressure measuring device, characterized in that: it includes a gas buffer chamber, wherein a pressure gauge for detecting tire internal pressure, an exhaust pipe for venting the gas buffer chamber, an air guide pipe for introducing tire gas into the gas buffer chamber, and a thermometer for detecting tire internal temperature are respectively installed on the upper, lower, left, and right sides of the gas buffer chamber; an air valve nut for connecting to the tire valve is connected to the end of the air guide pipe away from the gas buffer chamber; and an exhaust valve is connected to the exhaust pipe.
[0007] A further improvement is that the gas buffer chamber is a PVC gas buffer chamber.
[0008] A further improvement is that the gas buffer chamber is 300mm long, 50mm in diameter, and 5mm thick.
[0009] A further improvement is that the gas buffer chamber is provided with mounting holes on the top, bottom, left, and right sides for installing a pressure gauge, an exhaust pipe, a gas guide pipe, and a temperature gauge.
[0010] A further improvement is that the diameter of the mounting hole is 13mm.
[0011] A further improvement is that the air guide tube is a rubber tube with a diameter of 13mm.
[0012] A further improvement is that the exhaust valve is a DN20 ball valve.
[0013] A further improvement is that the pressure gauge is a psi pressure gauge with a range of 0-160 psi.
[0014] A further improvement is that the thermometer is a high-sensitivity thermometer with a range of -40 to 230°C; the probe of the thermometer extends into the gas buffer chamber without affecting the connection end of the gas delivery tube on the other side.
[0015] Compared with existing technologies, the above technical solution has the following advantages:
[0016] It can quickly and effectively detect the internal temperature and pressure of tires from the outside, which can avoid the inability to accurately manage the thermal dynamics of tire pressure due to the lack of built-in tire temperature and pressure equipment in mines, and effectively improve the service life of tires.

[0021] See Figures 1-2 As shown, the technical solution adopted in this specific embodiment is: a tire internal temperature and internal pressure measuring device, characterized in that: it includes a gas buffer chamber 1, and the gas buffer chamber 1 is respectively equipped with a pressure gauge 4 for detecting tire internal pressure, an exhaust pipe 5 for venting gas from the gas buffer chamber 1, an air guide pipe 2 for introducing tire gas into the gas buffer chamber 1, and a thermometer 7 for detecting tire internal temperature. The end of the air guide pipe 2 away from the gas buffer chamber 1 is connected to a valve nut 3 for connecting to the tire valve. An exhaust valve 6 is connected to the exhaust pipe 5.
[0022] The gas buffer chamber 1 is a PVC gas buffer chamber.
[0023] The gas buffer chamber 1 is 300mm long, 50mm in diameter, and 5mm thick.
[0024] The gas buffer chamber 1 has mounting holes on its top, bottom, left, and right sides for installing a pressure gauge 4, an exhaust pipe 5, a gas guide pipe 2, and a thermometer 7.
[0025] The diameter of the mounting hole is 13mm.
[0026] The air guide tube 2 is a rubber tube with a diameter of 13mm.
[0027] The exhaust valve 6 is a DN20 ball valve.
[0028] Among them, the pressure gauge 4 is a psi pressure instrument with a range of 0-160psi.
[0029] The thermometer 7 is a high-sensitivity thermometer with a range of -40 to 230°C; the probe of the thermometer 7 extends into the gas buffer chamber 1 without affecting the connection end of the gas guide tube 2 on the other side.
[0030] The fabrication and installation process consists of 5 steps:
[0031] 1) Fabricate the PVC gas buffer chamber by selecting PVC rods with a diameter of 50mm and a length of 300mm, machining and hollowing out the interior, controlling the wall thickness to 5mm, and simultaneously... Figure 1 As shown, four 13mm mounting holes are made on the top, bottom, left, and right sides of the PVC gas buffer chamber;
[0032] 2) Connect the air nozzle nut to the PVC gas buffer chamber via a rubber tube and then to the mounting hole on the left side.
[0033] 3) Install the exhaust pipe into the mounting hole below the PVC gas buffer chamber, install the DN20 ball valve on the exhaust pipe, and ensure that the ball valve opens and closes properly;
[0034] 4) Install the pressure gauge into the upper mounting hole. The pressure gauge is a psi meter with a range of 0-160 psi.
[0035] 5) Install the high-sensitivity thermometer into the mounting hole on the right side of the PVC gas buffer chamber. The thermometer's range is -40 to 230℃. Note that the thermometer's probe should not press against the base of the gas inlet tube on the left side.
[0036] The working principle of this invention is as follows: During use, the valve nut is connected to the tire's air inlet. High-temperature, high-pressure gas from inside the tire is guided through the air pipe to the PVC gas buffer chamber of the equipment. The temperature and pressure of the introduced gas are measured using a pressure gauge and a thermometer. After measurement, the valve nut is disconnected from the tire, and then the ball valve is opened to discharge the gas from the buffer chamber through the exhaust pipe. This allows for rapid and effective external measurement of the tire's internal temperature and pressure, avoiding the inability to accurately manage tire pressure dynamics in mines without built-in tire temperature and pressure monitoring equipment, thus effectively improving tire lifespan.
