Description

Technical Field

[0001] This utility model relates to the technical field of wheel radial fatigue testing machines, and in particular to an adjustable wheel radial fatigue testing machine. Background Technology

[0002] The adjustable wheel radial fatigue testing machine mainly simulates the radial loads and impacts experienced by wheels during actual use. By repeatedly loading and unloading the wheels, it tests their fatigue life and performance. The testing machine typically consists of a loading system, a control system, a measurement system, and a safety protection system.

[0003] In the process of using the existing wheel radial fatigue testing machine, the wheel must first be installed on the fixing device of the testing machine and tightened with special tools to ensure that the contact surface between the wheel and the test shaft is tight and without gaps. According to the test requirements, the corresponding test parameters, such as test speed, load, rotation direction, etc., are input. After confirming that all settings are correct, the testing machine is started to carry out the test.

[0004] The existing wheel radial fatigue testing machine requires manual lifting of the tire to the test shaft for installation. Due to the different sizes of tires, the installation process may be time-consuming due to the excessive weight of larger tires, and there is also the possibility of worker injury. The operation is also quite troublesome. Utility Model Content

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 , Figure 3 ,and Figure 4This is the first embodiment of the present invention. This embodiment provides an adjustable wheel radial fatigue testing machine, including a base 1, a support frame 2 fixed on the top of the base 1, a drum 3 rotatably connected inside the support frame 2 via bearings, a lifting box 4 slidably connected to the top of the base 1, a lifting assembly 5 installed inside the lifting box 4, and a protective assembly 6 installed on the top of the support frame 2. The lifting assembly 5 includes a sliding groove 501 on the outer wall of the lifting box 4, a connecting plate 509 slidably connected to the inner side of the sliding groove 501, a limiting seat 502 symmetrically fixed at the bottom of the connecting plate 509, a bidirectional lead screw 503 inserted inside the lifting box 4, a slider 504 symmetrically slidably connected to the outer wall of the bidirectional lead screw 503, a connecting strip 505 symmetrically movably connected to the top of the slider 504, and the end of the connecting strip 505 away from the slider 504 movably connected to the inside of the limiting seat 502.

[0031] Specifically, a lifting motor 506 is fixed to the outer wall of the lifting box 4 via a support plate. The output end of the lifting motor 506 is fixed to one end of a two-way lead screw 503. An electric push rod 507 is fixed to the top of the base 1. The telescopic end of the electric push rod 507 is fixed to the outer wall of the lifting box 4. The lifting box 4 is slidably connected to the top of the base 1 via a slide rail. A tire 508 is installed on the end of the connecting plate 509 near the drum 3 via a test shaft. When the connecting plate 509 slides to the highest point, the axis of the tire 508 and the axis of the drum 3 are on the same horizontal plane. A rotating rod is fixed inside the drum 3. The rotating rod is installed inside the support frame 2 by passing through the fixed seat. A transmission motor 7 is fixed to the top of the support frame 2. A main pulley is fixed to the output end of the transmission motor 7. A driven pulley is fixed to one end of the rotating rod. The driven pulley and the main pulley are connected by a belt drive. A cover plate 8 is fixed to the side of the support frame 2 near the main pulley. A protective frame 9 is fixed to the top of the base 1.

[0032] Furthermore, when the tire 508 is to be installed onto the connecting plate 509, the lifting motor 506 is started to drive the double-acting screw 503 to rotate. Then, the double-acting screw 503 drives the two sliders 504 to slide in opposite directions. Then, the sliding drives the connecting bar 505 to rotate. Then, the connecting bar 505 drives the connecting plate 509 to slide from the sliding groove 501 to the optimal installation position. Then, the tire 508 is installed. After installation, the tire 508 is raised and lowered from the sliding groove 501 through the connecting plate 509 until the axis of the tire 508 is on the same horizontal plane as the axis of the drum 3. Then, the drive motor 7 drives the drum 3 to rotate. Then, the electric push rod 507 drives the lifting box 4 to slide. Then, the lifting box 4 drives the connecting plate 509 to slide, thereby driving the tire 508 to slide to contact the contact surface of the drum 3 for testing.

[0033] Example 2

[0034] Reference Figure 1 , Figure 2 , Figure 3, Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The protective component 6 includes a water tank 601 fixed on the top of the support frame 2. A spray plate 602 is fixed on the side of the support frame 2 near the drum 3. The top of the spray plate 602 is connected to the outer wall of the water tank 601 through a water pipe. A water pump 606 is installed on one side of the water tank 601. Spray nozzles 603 are fixed at equal intervals at the bottom of the spray plate 602.

[0035] Specifically, a smoke detector 604 is fixed inside the support frame 2, and a buzzer 605 is connected to one side of the smoke detector 604.

[0036] Furthermore, when the testing machine overheats due to prolonged overload operation, which in turn causes a fire, the smoke alarm 604 transmits a signal to the buzzer 605 to trigger an alarm. Then, the water pump 606 is manually turned on to transfer water from the water tank 601 to the spray plate 602 through the water pipe, and then sprays it out from the nozzle 603 to carry out fire extinguishing work.

[0037] Working principle: When the tire 508 is to be installed onto the connecting plate 509, the lifting motor 506 is started to drive the double-acting screw 503 to rotate. The double-acting screw 503 then drives the two sliders 504 to slide in opposite directions, which in turn drives the connecting bar 505 to rotate. The connecting bar 505 then drives the connecting plate 509 to slide from the sliding groove 501 to the optimal installation position, where the tire 508 is installed. After installation, the tire 508 is raised and lowered from the sliding groove 501 via the connecting plate 509 until the axis of the tire 508 is on the same horizontal plane as the axis of the drum 3. Then, the transmission... Motor 7 drives drum 3 to rotate, and then electric push rod 507 drives lifting box 4 to slide. Lifting box 4 then drives connecting plate 509 to slide, which in turn drives tire 508 to slide to contact the drum 3 for testing. If the test machine overheats due to prolonged overload operation, causing a fire, the smoke alarm 604 transmits a signal to buzzer 605 to sound an alarm. Then, the water pump 606 is manually turned on to transfer water from water tank 601 to spray plate 602 through water pipe, and then sprays it out from nozzle 603 to extinguish the fire.
