[0025] This embodiment is a belt fatigue test device.

[0026] As Figures 1-4 shown, it includes a substrate 1. One end of the outer surface of the upper end of the substrate 1 is fixedly installed with a transmission test structure 2, and the other end of the outer surface of the upper end of the substrate 1 is fixedly installed with a fatigue test component 3. A test belt 4 is arranged between the transmission test structure 2 and the fatigue test component 3. The transmission test structure 2 includes a motor 5, a rotating shaft 6 and a first pulley 7. The fatigue test component 3 includes a base box 8, a lifting plate 9, a hydraulic rod 10, a guide ring 11, a guide rod 12, a pressure sensor 13, a fixed block 14, a connection plate 15, a second pulley 16 and a driven shaft 17, and the test belt 4 is drivingly connected between the first pulley 7 and the second pulley 16.

[0027] The motor 5 is fixedly installed at one end of the outer surface of the upper end of the substrate 1. The rotating shaft 6 is connected to one end of the output shaft in the motor 5. The first pulley 7 is fixedly installed on the outer wall of the rotating shaft 6 away from the motor 5. A coupling is provided between the rotating shaft 6 and the motor 5. The outer surface of one end of the rotating shaft 6 away from the first pulley 7 is fixedly connected to the outer surface of one end of the output shaft in the motor 5 through the coupling. The lower outer surface of the base box 8 is fixedly connected to the upper outer surface of the substrate 1. The number of the guide rings 11 and the guide rods 12 is two groups each. The two groups of guide rings 11 are fixedly installed at the left and right ends of the upper outer surface of the base box 8. The hydraulic rod 10 is fixedly installed in the middle of the base box 8. The upper outer surfaces of the two guide rods 12 are fixedly connected to the left and right ends of the lower outer surface of the lifting plate 9. The upper outer surface of the piston rod in the hydraulic rod 10 is fixedly connected to the middle of the lower outer surface of the lifting plate 9. The outer wall of the guide rod 12 is slidably connected to the guide ring 11. The lower end of the guide rod 12 passes through the guide ring 11 and extends into the interior of the base box 8. The pressure sensor 13 is fixedly installed between the middle of the upper outer surface of the lifting plate 9 and the middle of the lower outer surface of the fixed block 14. The connecting disk 15 is fixedly installed on the upper outer surface of the fixed block 14. The driven shaft 17 is connected to the middle of the outer surface of one side of the connecting disk 15.

[0028] It should be noted that the present utility model is a belt fatigue testing device. The provided transmission testing structure 2 and fatigue testing component 3, when conducting an experiment on the test belt 4, drive the second pulley 16 to descend through the operation of the hydraulic rod 10, shortening the distance between the second pulley 16 and the first pulley 7, facilitating the installation of the test belt 4 on the second pulley 16 and the first pulley 7. During the test, it is necessary to tighten the test belt 4. The second pulley 16 is driven to rise through the operation of the hydraulic rod 10, and the test belt 4 is tightened between the second pulley 16 and the first pulley 7. At this time, the pressure sensor 13 monitors the pressure value during tightening. The rotating shaft 6 is driven to rotate through the operation of the motor 5. The rotating shaft 6 drives the first pulley 7 to rotate. The first pulley 7 drives the test belt 4 to transmit in and out. The test belt 4 operates for a long time for fatigue testing. The manifestations of belt fatigue mainly include breakage and reduced working efficiency. The reduction in working efficiency is mainly manifested as the test belt 4 becoming loose. When the above situations occur, the force values detected by the pressure sensor 13 will all decrease. The pressure sensor 13 transmits the values to an external terminal for analysis, facilitating the improvement of the accuracy of the experiment, and the structure is simple and the cost is low.
