[0025] A tire high temperature resistance testing device comprises a test box 1, a heating chamber 2 is arranged on the left side inside the test box 1, a motor 3 is fixedly installed on the top of the test box 1 and located outside the heating chamber 2, a tire fixing mechanism 4 is fixedly installed on the top of the heating chamber 2 and located on the output end of the motor 3, an electric heating pipe rack 5 is fixedly installed on the left side inside the heating chamber 2, a waste collection box 6 is slidably connected to the bottom end inside the heating chamber 2, and a gas filtering component 7 and a cooling component 8 are respectively installed on the right side inside the test box 1.
[0026] Firstly, a heat insulation board 101 is fixedly connected to the interior of the test box 1 and on the inner wall of the heating chamber 2, and a box door 102 is rotatably connected to the front of the test box 1 and on the outer side of the heating chamber 2. A transparent observation window 103 is fixedly installed on the outer side of the box door 102. When the tire high temperature resistance test is carried out in the heating chamber 2, the heat is isolated by the heat insulation board 101 to prevent heat loss and prevent the tester from touching the outer side of the test box 1 and causing burns. The test tire is taken in and placed through the box door 102, and the test situation can be observed through the transparent observation window 103 during the test.
[0027] Then, the tire fixing mechanism 4 includes a connecting shaft 401 fixedly mounted on the driving end of the motor 3, a connecting sleeve 402 is slidably connected to the outer side of the connecting shaft 401, a guide plate 403 is fixedly connected to the bottom end of the connecting shaft 401, a spring 404 is sleeved on the outer side of the connecting shaft 401 and located between the guide plate 403 and the connecting sleeve 402, and the upper and lower ends of the spring 404 are respectively fixedly connected to the connecting sleeve 402 and the guide plate 403, a plurality of groups of fixed jaws 405 are rotatably connected to the outer side of the connecting sleeve 402, a handle 406 is symmetrically connected to the outer side of the connecting sleeve 402, a guide groove 407 adapted for use with the fixed jaws 405 is provided on the outer side of the guide plate 403, and the top ends of the plurality of groups of fixed jaws 405 are connected to the guide plate 403 through a rotating shaft 408. The connecting sleeve 402 is rotatably connected. When the tire is subjected to a high temperature resistance test, the box door 102 is opened and the connecting sleeve 402 is slid down through the handle 406. Under the guidance of the guide groove 407 and the connection of the rotating shaft 408, the multiple sets of fixed jaws 405 are driven to open. Then other testers put the tire into the inner side of the multiple sets of fixed jaws 405, and then release the handle 406 to push up the connecting sleeve 402 under the reset of the spring 404, so that the multiple sets of fixed jaws 405 clamp and fix the tire. After that, the box door 102 is closed and the multiple sets of electric heating tubes in the electric heating tube rack 5 are started for heating. During the heating process, the motor 3 is started to drive the connecting shaft 401 to rotate slowly, so that the outer side of the tire is evenly heated to improve the accuracy of the test results.

A drainage pipe 603 is fixedly connected to the front of the test box 1 and at the bottom of the heating chamber 2. When part of the product melts, the dripping waste is collected by the waste collection box 6 on the top of the bracket 601. When the tire is taken out later and cooled by the cooling assembly 8, the dripping water enters the interior of the waste collection box 6 and is discharged through the drainage holes 602, and finally can be discharged through the drainage pipe 603.
[0029] Secondly, the gas filter assembly 7 includes an exhaust fan 701 fixedly installed on the upper right side of the test box 1.

An exhaust hole 704 is provided between the filter chamber 702 and the heating chamber 2. During the high temperature resistance test, some toxic and harmful gases will be generated by the high-temperature rubber tire. In order to avoid inhalation by the staff when taking out the tire, before taking out the tire, the exhaust fan 701 is started to draw the gas in the heating chamber 2 into the filter chamber 702, and then the gas is discharged after being filtered by the two groups of activated carbon filters 703, thereby improving the safety of the test process. At the same time, the two groups of activated carbon filters 703 can be drawn out from the inside of the filter chamber 702 for replacement.
[0030] Finally, the cooling assembly 8 includes a water tank 801 fixedly installed at the lower right corner of the test box 1, a water pump 802 is fixedly installed inside the test box 1 and on the left side of the water tank 801, the input end of the water pump 802 is connected to the inside of the water tank 801, the output end of the water pump 802 is fixedly connected to a water pipe 803, the end of the water pipe 803 away from the water pump 802 and located inside the heating chamber 2 is fixedly installed with a water spray box 804, and the left side of the water spray box 804 is fixedly connected with a plurality of groups of nozzles 805. Before the tested tire is taken out, the temperature in the heating chamber 2 is still relatively high, and the tire and waste cannot be taken out directly. At this time, the water pump 802 is started to pump the water in the water tank 801 into the water spray box 804 through the water pipe 803, and finally the plurality of nozzles are sprayed out 805 to cool the heating chamber 2 and the tire, thereby facilitating the rapid removal of the tire and waste and improving the efficiency of the test.

During the heating process, the motor 3 is started to drive the connecting shaft 401 to rotate slowly, so that the outer side of the tire is evenly heated. When some products fail During raw melting, the dripping waste is collected by the waste collection box 6 on the top of the bracket 601. Before the tested tire is taken out, the temperature in the heating chamber 2 is still relatively high, and the tire and the waste cannot be taken out directly. At this time, the water pump 802 is started to pump the water in the water tank 801 into the water spray box 804 through the water pipe 803, and finally the heating chamber 2 and the tire are cooled by spraying 805 through multiple groups of nozzles, so as to facilitate the rapid removal of the tire and the waste and improve the test efficiency. The whole operation process is simple and convenient. Compared with the existing tire high temperature resistance test equipment, the utility model is designed to make the outer side of the tire evenly heated to improve the accuracy of the test results, and at the same time facilitate the rapid removal of the tire and the waste to improve the test efficiency.
