[0007] Preferably, the moving component further includes a turntable fixedly connected to the end of the first screw, and a handle is fixedly connected to the turntable at an eccentric position.
[0008] Preferably, the top of the base is provided with a stabilizing component, the stabilizing component includes a mounting frame fixedly connected to the top of the base, the mounting frame has a placement groove inside, an auxiliary wheel is rotatably connected inside the placement groove, and two ramps are fixedly connected to the outside of the mounting frame, the bottom of the ramps being fixedly connected to the top of the base.

[0012] The advantages of this utility model are:
[0013] 1. This utility model uses a handle to rotate a turntable, which in turn rotates a first screw, causing the first screw to move and thus moving the slide cylinders away from the test wheel. This causes the gear ring to move, separating the insertion rod from the insertion hole and simultaneously separating the rotating ring from the auxiliary groove. This allows the test wheel to detach and be supported by a stabilizing component, making test wheel replacement more convenient and reducing replacement time, thereby improving work efficiency. In addition, the replacement of the test wheel facilitates testing the caster under different road conditions, enhancing the practicality of the device.

This utility model pushes the experimental wheel, causing it to move up the slope to the top of the mounting frame and then to the top of the auxiliary wheel, thus facilitating the subsequent installation of the experimental wheel. When the experimental wheel rotates, it drives the auxiliary wheel to rotate, thereby ensuring the smooth rotation of the experimental wheel. Attached Figure Description

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1
[0024] Please see Figure 1-5As shown, a heavy-duty caster walking test machine includes a base 1. A mounting assembly is provided on the top of the base 1. The mounting assembly includes two upright plates 2 fixedly connected to the top of the base 1. A PLC control device 3 is fixedly connected to the outside of one of the upright plates 2.

There are two first transmission rods 8. A rotating ring 10 is rotatably connected to the outside of the first transmission rod 8. A first motor 7 is fixedly connected to the end of one of the first transmission rods 8. The end of the other first transmission rod 8 is fixedly connected to the inside of the slide cylinder 4. The outside of the first motor 7 is fixedly connected to the inside of the slide cylinder 4.
[0025] During operation, by moving the two sliding cylinders 4 away from the experimental wheel 11, the toothed ring 5 is moved, causing the insertion rod 6 to separate from the insertion hole 13. At the same time, the rotating ring 10 is separated from the auxiliary groove 12, thus causing the experimental wheel 11 to detach. The experimental wheel 11 can then be supported by the stabilizing component, making the replacement of the experimental wheel 11 more convenient and reducing the time required, thereby improving work efficiency. In addition, the replacement of the experimental wheel 11 facilitates testing the caster under different road conditions, improving the practicality of the device.
[0026] Among them, an experimental component is provided on the outside of the toothed ring 5. The experimental component includes an experimental wheel 11 that abuts against the outside of the toothed ring 5. Two auxiliary grooves 12 are opened inside the experimental wheel 11. An insertion hole 13 is opened inside the experimental wheel 11. The auxiliary grooves 12 are slidably connected to the outside of the rotating ring 10, and the insertion hole 13 is slidably connected to the outside of the insertion rod 6.
[0027] During operation, the insertion rod 6 is inserted into the insertion hole 13, thereby connecting the test wheel 11 to the mounting assembly. This facilitates the rotation of the test wheel 11 by the first motor 7, thus enabling experiments on the caster.
[0028] The slide cylinder 4 is provided with a moving component on its outer side. The moving component includes a limiting strip 14 that is slidably connected to the inside of the slide cylinder 4. The limiting strip 14 is fixedly connected to the inside of the upright plate 2. A first screw 15 is rotatably connected to the outside of the slide cylinder 4. The first screw 15 passes through the upright plate 2 and is threadedly connected.
[0029] The movable component also includes a turntable 16 fixedly connected to the end of the first screw 15, and a handle 17 is fixedly connected to the turntable 16 at an eccentric position.
[0030] During operation, by turning the handle 17, the turntable 16 is rotated, which in turn rotates the first screw 15, causing the first screw 15 to move, which in turn moves the slide cylinder 4, thus facilitating the disassembly and installation of the experimental wheel 11, and making it convenient to replace the experimental wheel 11 to conduct experiments on different road conditions.
[0031] The base 1 has a stabilizing component on its top, which includes a mounting frame 18 fixedly connected to the top of the base 1. The mounting frame 18 has a placement groove 19 inside, and an auxiliary wheel 20 is rotatably connected inside the placement groove 19. Two ramps 21 are fixedly connected to the outside of the mounting frame 18, and the bottom of the ramps 21 is fixedly connected to the top of the base 1.
[0032] During operation, by pushing the experimental wheel 11, the experimental wheel 11 is moved up the ramp 21 to the top of the mounting frame 18, and then moved up the auxiliary wheel 20, which facilitates the subsequent installation of the experimental wheel 11.
[0033] When the experimental wheel 11 rotates, it will drive the auxiliary wheel 20 to rotate, thus ensuring the smooth rotation of the experimental wheel 11.
[0034] The PLC control device 3 is electrically connected to the second motor 22 and the PLC control device 3 is electrically connected to the first motor 7.
[0035] During operation, the first motor 7 and the second motor 22 are controlled by the PLC control device 3 to ensure the stable operation of the device.
[0036] Example 2
[0037] Please see Figure 2 As shown in the first embodiment, as another implementation of this utility model, a working component is provided on the outside of the base 1. The working component includes a second motor 22 fixedly connected to the bottom of the inner cavity of the base 1. A second transmission rod 23 is fixedly connected to the transmission end of the second motor 22. The end of the second transmission rod 23 is rotatably connected to the top of the inner cavity of the base 1. A second gear 24 is fixedly connected to the outside of the second transmission rod 23.
[0038] The working assembly also includes four third gears 25 meshing with the outer side of the second gear 24. A second screw 26 is fixedly connected inside the third gear 25. The bottom of the second screw 26 is rotatably connected to the bottom of the inner cavity of the base 1. The second screw 26 passes through the base 1 and is rotatably connected. A top frame 27 is rotatably connected to the top of the second screw 26. A pressing frame 28 is threadedly connected to the outer side of the second screw 26. A mounting base 29 is fixedly connected to the bottom of the pressing frame 28.
[0039] During operation, the second motor 22 drives the second transmission rod 23 to rotate, which in turn drives the second gear 24 to rotate, which in turn drives the third gear 25 to rotate, which in turn drives the second screw 26 to rotate, which in turn drives the pressing frame 28 to move, which in turn drives the mounting base 29 to move, which in turn drives the casters mounted on the outside of the mounting base 29 to move, so that the casters can abut against the outside of the experimental wheel 11, thus facilitating the experiment on the casters.
[0040] The working principle is as follows: by rotating the handle 17, the turntable 16 rotates, which in turn rotates the first screw 15, causing the first screw 15 to move. This moves the slide cylinder 4, causing the two slide cylinders 4 to move away from the experimental wheel 11. This, in turn, moves the gear ring 5, causing the insertion rod 6 to separate from the insertion hole 13. At the same time, it causes the rotating ring 10 to separate from the auxiliary groove 12, thus causing the experimental wheel 11 to detach. The experimental wheel 11 can then be supported by the stabilizing component, making the replacement of the experimental wheel 11 more convenient and reducing the time required for replacement, thereby improving work efficiency. In addition, the replacement of the experimental wheel 11 facilitates testing the caster under different road conditions, improving the practicality of the device.
