Description

Technical Field

[0001] The present invention relates to the technical field of belt wear testing, and in particular to a belt wear testing device based on visual sensing. Background Art

[0002] A belt is a belt-like device used to transmit power, transport materials, or achieve mechanical linkage, typically made of flexible materials. In the two-wheeled vehicle industry, the belt is a key component in the drivetrain, responsible for transmitting power and ensuring smooth vehicle operation. Its quality and durability directly impact the vehicle's overall performance, driving experience, and safety. During two-wheeled vehicle belt testing, factors such as the tire's moment of inertia and mass distribution can affect the belt's force and motion. To minimize deviations due to actual conditions, testing requires connecting the tire to the belt.

[0003] In the existing technology, when performing wear tests on belts, in order to ensure the stability of the test process, the wheels need to be supported by a support frame. When conducting comparative tests on different belts, the original screws and other connecting parts on the support frame have to be removed first, exposing the tire and belt to the outside before removing the old belt. The entire operation process is complicated and tedious, consuming a lot of manpower, material resources and time costs. Summary of the Invention

When conducting comparative tests on different belts, it is necessary to first remove the original screws and other connecting parts on the support frame, so that the tire and belt can be exposed before removing the old belt. The entire operation process is complicated and tedious, and a lot of manpower and time costs are wasted.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: The present invention provides a belt wear testing device based on visual sensing, comprising: The placing part includes a support frame fixedly connected to the upper surface of the workbench, the top of the support frame is rotatably connected to a flat fork, the inner part of the flat fork is rotatably connected to the tire, the workbench is connected to a driving wheel through a motor provided on its upper surface, the driving wheel is connected to a driving wheel fixedly connected to the outer side of the tire through a belt engaged with its circumferential outer surface, and the workbench is provided with a support member for supporting the position of the tire through a slide groove provided on its upper surface; The friction part includes a visual sensor, and the workbench is provided with a friction member through a receiving cavity opened on its upper surface; Among them, the support member includes a moving frame. There are two moving frames, which are symmetrically distributed on both sides of the tire. The moving frames are slidably connected to the inside of the sliding groove through connecting plates fixed to their bottoms. A connecting column is fixedly connected to the side of the flat fork away from the tire. A moving groove is formed inside the moving frame, which fits the circumferential outer surface of the connecting column. An adjusting component for changing the position of the moving frame is provided inside the accommodating cavity.

[0006] Further, the friction member includes a friction wheel that fits the outer surface of the tire. A stop block is connected to the side of the friction wheel close to the moving frame. A guide rod is fixedly connected to the bottom of the stop block. A spring connected to the bottom of the stop block is sleeved on the circumferential outer surface of the guide rod. One end of the spring away from the stop block is connected to a bottom plate that slides on the outer surface of the guide rod. The bottom plate is slidably connected to the inner wall surface of the accommodating cavity through a buckle fixed to its outside.

[0007] Further, the sliding grooves are symmetrically distributed on both sides of the accommodating cavity. An L-shaped groove communicating with the inside of the sliding groove is formed inside the workbench, and the inside of the L-shaped groove communicates with the inside of the accommodating cavity.

[0008] Further, the adjusting component includes a connecting plate that slides on the inner wall surface of the L-shaped groove. The connecting plate is fixedly connected to the side of the connecting plate close to the tire. A hydraulic cylinder is fixedly connected to the inside of the accommodating cavity. The output end of the hydraulic cylinder is fixedly connected to a push plate that fits the upper surface of the connecting plate.

At this time, the tire and the transmission wheel are exposed and not shielded by the movable frame, which is convenient for disassembling or installing the belt on the circumferential outer surfaces of the driving wheel and the transmission wheel. Importantly, during this process, no additional tools are required to separate the tire and the movable frame, greatly reducing the risk of damage to the tire, the movable frame and other related components caused by operation errors, effectively extending the service life of the equipment, significantly reducing the maintenance and replacement costs. At the same time, the cumbersome disassembly and installation steps are reduced, greatly saving time and labor costs, making the entire belt disassembly and installation process more efficient and convenient, and effectively improving the work efficiency.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Embodiment:

[0020] Please refer to Figures 1 - 10 , the present invention provides a technical solution: a belt wear test device based on vision sensing, comprising: Placement part 1, the placement part 1 includes a support frame 12 fixedly connected to the upper surface of the workbench 11, the top end of the support frame 12 is rotatably connected with a flat fork 13, the inside of the flat fork 13 is rotatably connected with a tire 14, the workbench 11 is drivenly connected with a driving wheel 151 through a motor arranged on its upper surface, the driving wheel 151 is drivenly connected with a driven wheel 152 fixedly connected to the outside of the tire 14 through a belt meshed on the outer circumference of the driving wheel 151, the workbench 11 is provided with a support member 16 for supporting the position of the tire 14 through a chute 111 opened on its upper surface, and the motor is driven through a driving power source at the bottom of the workbench 11.

[0021] Friction part 2, the friction part 2 includes a vision sensor 21, and the workbench 11 is provided with a friction member 22 through a receiving cavity opened on its upper surface; Among them, the support member 16 includes a movable frame 161. There are two movable frames 161, which are symmetrically distributed on both sides of the tire 14. The movable frame 161 is slidably connected to the inside of the chute 111 through a connecting plate 162 fixed to its bottom. A connecting column 163 is fixedly connected to one side of the flat fork 13 away from the tire 14. A moving groove 164 that fits the circumferential outer surface of the connecting column 163 is formed inside the movable frame 161. The moving groove 164 is designed in an open type. The moving groove 164 includes an arc groove and a straight groove, and the arc groove and the straight groove are internally connected. An adjusting component 17 for changing the position of the movable frame 161 is arranged inside the accommodating cavity.

[0022] The friction member 22 includes a friction wheel 221 that fits the outer surface of the tire 14. A stop block 222 is connected to one side of the friction wheel 221 close to the movable frame 161. A guide rod 223 is fixedly connected to the bottom of the stop block 222. A spring 224 connected to the bottom of the stop block 222 is sleeved on the circumferential outer surface of the guide rod 223. One end of the spring 224 away from the stop block 222 is connected to a bottom plate 225 that slides on the outer surface of the guide rod 223. The bottom plate 225 is slidably connected to the inner wall surface of the accommodating cavity through a buckle fixed on its outside.

[0023] The chutes 111 are symmetrically distributed on both sides of the accommodating cavity. An L-shaped groove 112 communicating with the inside of the chute 111 is formed inside the workbench 11. The inside of the L-shaped groove 112 communicates with the inside of the accommodating cavity. There are two L-shaped grooves 112, which are symmetrically arranged on both sides of the tire 14.

[0024] The adjusting component 17 includes a connecting plate 171 that slides on the inner wall surface of the L-shaped groove 112. The connecting plate 171 is fixedly connected to one side of the connecting plate 162 close to the tire 14. A hydraulic cylinder is fixedly connected inside the accommodating cavity. The output end of the hydraulic cylinder is fixedly connected to a push plate 172 that fits the upper surface of the connecting plate 171. A resetting member 173 is arranged through a through groove formed in the push plate 172.

[0025] The resetting member 173 includes a limiting column 1731 slidably connected inside the through groove. A magnetic plate 1732 is fixedly connected to the upper surface of the inner wall of the accommodating cavity. The upper surface of the limiting column 1731 is magnetically designed to be magnetically connected to the lower surface of the magnetic plate 1732. One side of the limiting column 1731 close to the hydraulic cylinder is designed with an inclined side. The height of the limiting column 1731 is greater than the thickness of the push plate 172. One side of the magnetic plate 1732 close to the hydraulic cylinder is designed with a small arc surface.

[0026] A shaft rod 174 that slides on the inner wall surface of the L-shaped groove 112 is rotatably connected to the bottom of the bottom plate 225. A pushing plate 175 is fixedly connected to the outside of the shaft rod 174. A notch is formed on one side of the pushing plate 175 away from the bottom plate 225. A push rod 176 that fits the inner wall of the notch is fixedly connected to one end of the push plate 172 away from the hydraulic cylinder.

[0027] One end of the middle part of the push rod 176 close to the hydraulic cylinder adopts a planar design that fits the outer surface of the connecting plate 171.

[0028] The positioning column 18 is connected to the upper surface of the workbench 11 in a damped sliding manner. The positioning block 181 is fixedly connected to the outer circumferential surface of the positioning column 18. A positioning groove that fits the outer surface of the positioning block 181 is formed inside the moving frame 161. The notch of the positioning groove near the positioning block 181 adopts an inclined cone opening design.

[0029] During the driving process of the two-wheeler, there are complex interactions between the belt and the tire 14, including friction, tension changes, etc. Connecting the transmission wheel 152 to the tire 14 can more accurately simulate the working state of the belt during the actual operation of the two-wheeler, and more accurate belt wear data can be obtained, such as wear rate, distribution of wear parts, etc., making the test results more reliable and valuable for reference, and can truly reflect the wear situation of the belt in actual use.

[0030] The friction wheel 221 can adopt a roller belt or a roller. Resistance is given by pressing against the tire 14. The motor rotates to drive the driving wheel 151 to rotate. The driving wheel 151 drives the transmission wheel 152 to rotate through the belt meshed with its outer circumferential surface. The transmission wheel 152 is fixed to one side of the tire 14. When the tire 14 rotates, the friction wheel 221 will be driven to rotate passively.

[0031] The process of loading the belt: In the initial state, the moving frame 161 is on the side of the surface of the workbench 11 away from the motor. The friction member 22 is inside the accommodation cavity. The upper surface of the friction wheel 221 is flush with the upper surface of the workbench 11. The lowest point on the outer surface of the tire 14 is in contact with the upper surface of the friction wheel 221. The connecting column 163 is disengaged from the moving frame 161. The pushing plate 175 is in a horizontal state and is parallel to the lower surface of the inner wall of the accommodation cavity. The outer end of the shaft rod 174 is in contact with the circumferential inner wall of the L-shaped groove 112 (the L-shaped groove 112 is divided into a vertical section and a horizontal section. At this time, the outer end of the shaft rod 174 is at the junction of the vertical section and the horizontal section, that is, the bottom of the vertical section). The outer end of the push rod 176 is disengaged from the notch inside the pushing plate 175, and the vertical surface of the push rod 176 near the hydraulic cylinder is in contact with the side surface of the connecting plate 171. The inner part of the limit post 1731 is slidably connected inside the through groove. Under the action of its own gravity, the upper surface of the limit post 1731 is flush with the upper surface of the push plate 172. The lower surface of the limit post 1731 protrudes from the lower surface of the push plate 172 and is flush with the lower surface of the connecting plate 171 (the height of the limit post 1731 is greater than the height of the push plate 172). There is a certain distance between the side of the limit post 1731 near the push rod 176 and the side surface of the connecting plate 171. The connecting plate 171 slides on the side of the horizontal section of the L-shaped groove 112 near the hydraulic cylinder).

[0032] Take out the belt to be tested. One end is sleeved on the circumferential outer surface of the driving wheel 151 and meshes with the teeth on its outer surface. The other end is sleeved on the circumferential outer surface of the driven wheel 152 and meshes with the teeth on its outer surface (in the initial situation, the center point of the driven wheel 152 is lower than the center point of the driving wheel 151, and the center point of the driving wheel 151 is lower than the center point of the connecting ear at the top of the support frame 12). At this time, the straight-line distance between the center point of the driving wheel 151 and the center point of the driven wheel 152 is relatively short. The belt sleeved on the outer surfaces of the driving wheel 151 and the driven wheel 152 is in a relatively loose state, and it is possible to easily sleeve the belt on the circumferential outer surfaces of the driven wheel 152 and the driving wheel 151).

[0033] Drive the hydraulic cylinder to drive the output end of the hydraulic cylinder to extend. The output end of the hydraulic cylinder is fixedly connected to the outside of the push plate 172. When the hydraulic cylinder outputs, the push plate 172 moves to the side away from the hydraulic cylinder. The push plate 172 slides the limit post 1731 through the through groove opened in it. The limit post 1731 moves together with the push plate 172. During the movement of the push plate 172, the side of it near the push rod 176 is in contact with the outer surface of the connecting plate 171 and drives the connecting plate 171 to slide in the L-shaped groove 112 towards the vertical section. During the movement, the moving frame 161 slides through the connecting plate 171. The connecting plate 162 at the bottom end of the moving frame 161 is at the edge position inside the sliding groove 111 and cannot move further).

[0034] Meanwhile, the limiting post 1731 inside the push plate 172 reaches the position below the magnetic plate 1732. The upper surface of the limiting post 1731 is subjected to the magnetic adsorption of the magnetic plate 1732 and slides upward inside the through groove until the upper surface of the limiting post 1731 fits against the lower surface of the magnetic plate 1732. The lower surface of the limiting post 1731 no longer protrudes from the lower surface of the push plate 172 but is hidden inside the through groove. The hydraulic cylinder continues to output, and the push plate 172 drives the limiting post 1731 to continue moving. Since the connecting plate 171 is limited by the sliding groove 111 through the connecting plate 162 and is fixed in this position without moving, after the upper surface of the limiting post 1731 separates from the magnetic plate 1732, the lower surface of the limiting post 1731 fits against the upper surface of the connecting plate 171 under the action of gravity.

[0035] During the movement of the connecting plate 171, the connecting plate 162 and the moving frame 161 move together in the direction close to the motor. The positioning post 18 slides vertically and dampedly on the upper surface of the workbench 11. The moving frame 161 includes a flat plate that fits against the upper part of the workbench 11. Initially, the height of the positioning block 181 is higher than the thickness of the flat plate. When the moving frame 161 is about to reach the side close to the motor within its movable range, the positioning post 18 enters the positioning groove inside the moving frame 161. By pressing the positioning post 18, the positioning post 18 and the positioning block 181 are moved downward as a whole, so that the outer surface of the positioning block 181 fits against the inner wall surface of the positioning groove (the notch at the position close to the positioning block 181 inside the positioning groove is designed with an inclined cone opening for guiding. Even if the position of the moving frame 161 is slightly offset, when the positioning block 181 is dampedly pressed down by the positioning post 18, it can also achieve the functions of position correction and fixation. The damped sliding can prevent falling off caused by vibration. At the same time, the positioning post 18 can always keep the positioning block 181 higher than the bottom of the moving frame 161 before the belt feeding), realizing the fixing function of the support member 16, stably fixing the moving frame 161 in this position and ensuring the stability of the tire 14 during the wear test.

[0036] During the movement of the connecting plate 171, the position of the tire 14 remains fixed, and the flat fork 13 and the connecting post 163 on its outer surface also remain fixed (the central axes of the connecting post 163, the tire 14, and the transmission wheel 152 are on the same axis). When the moving frame 161 approaches the position of the tire 14, the moving groove 164 smoothly receives the connecting post 163 inside the moving frame 161 (the moving groove 164 is designed with an opening. The moving groove 164 includes an arc groove and a straight groove, and the arc groove and the straight groove are internally connected. The connecting post 163 always slides inside the straight groove during the movement of the moving frame 161). When the moving frame 161 is fixed, the connecting post 163 is at the junction of the arc groove and the straight groove (the lowest end of the arc groove).

[0037] When the upper surface of the limit post 1731 is separated from the lower surface of the magnetic plate 1732 and the lower surface of the limit post 1731 is in contact with the upper surface of the connecting plate 171, the outer end of the push rod 176 enters the notch inside the push plate 175 under the output action of the hydraulic cylinder, and the circumferential outer surface of the push rod 176 is in contact with the circumferential inner wall of the notch. As the hydraulic cylinder continues to move, the shaft rod 174 is in the vertical section inside the L-shaped groove 112. The shaft rod 174 receives the thrust from the push rod 176 through the push plate 175, and the shaft rod 174 moves upward in the vertical section of the L-shaped groove 112. The push plate 175 gradually tilts as a whole. One side of the notch of the push plate 175 is lower, and the outer end of the push rod 176 in contact with the inner wall of the notch is always in the horizontal section of the L-shaped groove 112.

[0038] With the continuous output of the output end of the hydraulic cylinder, the tilt angle of the push plate 175 gradually increases. During this process, the push plate 175 drives the bottom plate 225 to move vertically upward inside the accommodation cavity through the shaft rod 174 at its top. When the shaft rod 174 moves upward, it drives the stopper 222 and the friction wheel 221 to move vertically upward synchronously through the guide rod 223. The upper surface of the friction wheel 221 will press against the bottom end of the circumferential outer surface of the tire 14 and lift the tire 14 upward. When the tire 14 moves upward, its whole will rotate inside the support frame 12 through the flat fork 13, and its upward movement path is arc-shaped (centered on the axis of the inner wall of the connecting ear at the top of the support frame 12).

[0039] Since the support frame 12 at the outer end of the flat fork 13 is fixed and the position of the driving wheel 151 is fixed, when the tire 14 rotates around the axis of the connecting ear at the top of the support frame 12, the straight-line distance between the center point of the driving wheel 151 and the center point of the transmission wheel 152 gradually becomes longer until the axis of the driving wheel 151, the axis of the inner wall of the connecting ear at the top of the support frame 12, and the axis of the transmission wheel 152 are in the same plane (this plane is in an inclined state, lower on the side close to the driving wheel 151 and higher on the side close to the transmission wheel 152). The outer end of the push rod 176 is at the junction of the vertical section and the horizontal section inside the L-shaped groove 112, and the outer end of the shaft rod 174 is at the top position of the vertical section inside the L-shaped groove 112 under the action of the push plate 175. The push plate 175 is also in a vertical state. The friction part 22 moves upward as a whole, and the outer surface of the friction wheel 221 is in close contact with the topmost part of the circumferential outer surface of the tire 14. At this time, the hydraulic cylinder stops output and is locked. At this time, the straight-line distance between the center point of the driving wheel 151 and the center point of the transmission wheel 152 is the longest, and the belt sleeved on the outer surfaces of the driving wheel 151 and the transmission wheel 152 can be automatically tightened without manual adjustment.

[0040] The process of testing the belt: Drive the driving wheel 151 to rotate through the drive motor. The circumferential outer surface of the driving wheel 151 drives the driven wheel 152 to rotate through the belt. The axis of the driven wheel 152 and the tire 14 are fixed together. The friction member 22 is in close contact with the upper tire 14 and applies resistance to the tire 14 during rotation, which can simulate the wear of the belt when the two-wheeler is loaded. There is a spring 224 between the stopper 222 and the bottom plate 225, which can continuously apply resistance to the lower surface of the tire 14 to reduce the gap. Test for the specified time, and monitor the wear of the belt through the vision sensor 21 arranged on the upper surface of the workbench 11. The vision sensor 21 obtains the image information of the belt surface, and then analyzes the image using an image processing algorithm to extract the characteristic parameters related to the belt wear, such as the area, shape, position of the wear area, and the texture change of the belt surface, etc., and records the relevant data.

[0041] Process of discharging the belt after the test is completed: After the test is completed, the motor stops. Lift the positioning posts 18 on both sides upward so that the positioning blocks 181 on the outer surface of the positioning posts 18 are disengaged from the positioning grooves inside the moving frame 161, releasing the safety lock. Start the hydraulic cylinder and restore the output end of the hydraulic cylinder to the initial position. The output end of the hydraulic cylinder drives the push plate 172 to move toward the side close to the hydraulic cylinder. The push rod 176 at the outer end of the push plate 172 moves in the horizontal section of the L-shaped groove 112 toward the hydraulic cylinder, and the shaft rod 174 inside the push plate 175 moves downward under the gravity of the upper friction member 22 and the tire 14 above it. The inner wall of the notch inside the push plate 175 always fits the outer surface of the push rod 176. The shaft rod 174 gradually moves downward in the vertical section of the L-shaped groove 112, while the push rod 176 gradually moves toward the side close to the hydraulic cylinder in the L-shaped groove 112 (the push rod 176 is inside the horizontal section during this process). During this process, the push plate 175 changes from a vertical state to an inclined state, the friction member 22 moves vertically downward inside the accommodation cavity, and the tire 14 rotates downward around the axis line of the connecting ear at the top of the support frame 12. At the same time, the flat fork 13 and the tire 14 rotate together. The connecting column 163 on the outside of the flat fork 13 slides downward and fits inside the arc-shaped groove in the moving groove 164, and the connecting column 163 reaches the junction of the arc-shaped groove and the straight groove. At this time, the upper surface of the friction wheel 221 is flush with the upper surface of the workbench 11, and the push plate 175 is in a horizontal state again, parallel to the lower surface of the inner wall of the accommodation cavity. And the center point of the tire 14 is lower than the center point of the driving wheel 151, and the distance between the center point of the driving wheel 151 and the center point of the driven wheel 152 decreases. In this state, the belt is placed slack on the outer surfaces of the driving wheel 151 and the driven wheel 152.

[0042] During the above process, the limit post 1731 moves together with the push plate 172. When the push plate 175 is completely in a horizontal state, the bottom end of the limit post 1731 no longer contacts the upper surface of the connecting plate 171, and its bottom end protrudes from the lower surface of the push plate 172. The hydraulic cylinder continues to move, and the outer circumferential surface of the outer end of the push rod 176 disengages from the inside of the push plate 175. The side of the push rod 176 close to the hydraulic cylinder contacts the side surface of the connecting plate 171. When the push plate 172 moves, it will drive the connecting plate 171 to move together. The outside of the connecting plate 171 is fixedly connected to the side surface of the connecting plate 162, driving the moving frame 161 and the connecting plate 162 to move away from the motor side inside the sliding groove 111. During this process, the limit post 1731 will be attracted upward when passing through the magnetic plate 1732. However, the outer side of the limit post 1731 is designed with a bevel. When the limit post 1731 moves in the direction of the hydraulic cylinder following the push plate 172, the bevel of the limit post 1731 contacts the magnetic plate 1732 and gradually moves vertically into the through groove.

[0043] In the initial process of the movement of the moving frame 161, the connecting post 163 outside the flat fork 13 slides in contact with the inside of the linear groove in the moving groove 164 until the connecting post 163 is completely separated from the moving frame 161. When the hydraulic cylinder fully returns to the contracted state, the moving frame 161 is at the outermost end away from the motor within its stroke range on the upper surface of the workbench 11. At this time, the tire 14 and the flat fork 13 are completely exposed on the upper surface of the workbench 11 through the support member 16, and the belt that is loosely hung on the outer surfaces of the driving wheel 151 and the transmission wheel 152 can be easily taken out without using external tools.

[0044] In summary, the device has the following advantages during the disassembly and assembly of the belt: Advantage 1. The flat fork 13 and the tire 14 are fixedly supported above the workbench 11 through the support member 16, which can ensure the stability during the wear test. When different belts need to be subjected to wear tests, by changing the position of the moving frame 161, the connecting post 163 outside the flat fork 13 slides in contact with the inner wall of the moving groove 164, and finally the separation of the flat fork 13 from the moving frame 161 is achieved. The tire 14 and the transmission wheel 152 will be exposed outside and not blocked by the moving frame 161, and the belt can be disassembled or installed on the outer circumferential surfaces of the driving wheel 151 and the transmission wheel 152. During this process, no additional tools are used to separate the tire 14 from the moving frame 161, which can reduce the possibility of damage to the tire 14, the moving frame 161 or other related components caused by improper operation, extend the service life of the equipment, reduce the maintenance and replacement costs, reduce the disassembly and installation steps, save time and labor costs, and make the entire belt disassembly and installation process more efficient and fast.

[0045] Advantage 2: In the initial state, the driving wheel 152 and the tire 14 are at a relatively low position, and the straight-line distance between the center point of the driving wheel 151 and the center point of the driving wheel 152 is relatively short, enabling the belt to be easily sleeved. The sleeved belt is in a relatively loose state, reducing the installation difficulty. There is no need to stretch the belt to a certain distance before sleeving it on the outer surfaces of the driving wheel 151 and the driven wheel 152, reducing the inaccuracy of the wear test results caused by excessive stretching of the belt during feeding. The belt feeding and installation can be completed without complex operations and tools.

[0046] Advantage 3: During feeding, the adjusting assembly 17 rotates the tire 14 upward around the center point of the connecting ear at the top of the support frame 12, thereby increasing the distance between the driving wheel 151 and the driven wheel 152 until the center points of the driving wheel 151, the connecting ear at the top of the support frame 12, and the driven wheel 152 can form a straight line. The distance between the driving wheel 151 and the driven wheel 152 is the longest, realizing automatic belt tensioning without manual adjustment, improving the efficiency of test preparation, and ensuring the consistency and accuracy of the belt tensioning force.

[0047] Advantage 4: After the test is completed, the adjusting assembly 17 can restore the device to the initial state. The tire 14 rotates downward around the center point of the connecting ear at the top of the support frame 12, and the distance between the driving wheel 151 and the driven wheel 152 becomes shorter. The belt is loosely placed on the outer surfaces of the driving wheel 151 and the driven wheel 152. After the hydraulic cylinder is restored, the moving frame 161 disengages from the flat fork 13. At this time, the tire 14 and the flat fork 13 are completely exposed, and the belt can be easily removed without the aid of external tools. The feeding process is simple and fast, improving the overall efficiency of the test.

[0048] Advantage 5: During the feeding process, when the moving frame 161 approaches the target position, the positioning block 181 automatically corrects its position through the inclined cone guide at the positioning groove on the surface of the moving frame 161, and can be accurately locked even if there is a certain position deviation. During the wear test, the horizontal position of the tire 14 is restricted by the moving frame 161 and cannot move left and right, while the vertical position of the tire 14 is restricted by the friction member 22, ensuring the stability of the device during the wear test. The lower surface of the limit post 1731 fits with the connecting plate 171 to form a mechanical hard limit, combined with hydraulic locking, with a relatively high anti-impact load. The double guarantee of the damping gravity self-locking of the limit post 1731 and the mechanical locking of the positioning post 18 prevents the moving frame 161 from slipping out of control.

[0049] Advantage 6: Through the elastic support of the bottom plate 225 and the spring 224, the friction wheel 221 applies a constant pressure to the tire 14, avoiding the problem that after a period of wear test, the surface of the tire 14 wears and no longer contacts the outer surface of the friction wheel 221, greatly reducing the resistance on the belt and resulting in inaccurate belt wear test results.
