They are usually installed on metal rims, can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects when driving, so they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance and flexibility resistance, as well as low rolling resistance and heat generation. Before leaving the factory, tires need to pass the corresponding pressure resistance, puncture resistance, wear resistance and other tests through special testing equipment, and only qualified products can be arranged to leave the factory.

[0019] The beneficial effects of the present invention are:

[0020] 1. The present invention uses a barrier sheet to block external debris to prevent the debris from falling into the storage chamber 1, which would increase the amount of impurities in the engine oil in the storage chamber 1. The engine oil in the slewing bearing is transported to the steel balls in the slewing bearing through the injection channel, making it more convenient for the slewing bearing to transport the engine oil. At the same time, the transport mechanism can remove the debris that falls into the steel balls in the slewing bearing, and replace the engine oil with some debris. The steel balls of the slewing bearing rotate continuously, and can maintain and decontaminate the steel balls in various positions. When the steel balls change, the adhered engine oil can be pulled to various positions, and the rings that constrain the steel balls in the slewing bearing can be decontaminated and maintained.

[0021] 2. In the present invention, when the extension piece rotates along with the rotating ring, the compression piece at the lower end of the extension piece rotates along with the extension piece. During the rotation of the compression piece, the compression piece extends into the inside of the inclined opening and presses the wall of the inclined opening, so that the movable piece is compressed and changes its position toward the slewing bearing, so that the engine oil flows through the second constraint piece to the tail of the injection channel. The lower end of the injection channel close to one side of the slewing bearing is reserved with a drain port. The engine oil passes through the drain port and the guide port, making it more convenient to maintain the slewing bearing with the engine oil. The filling of the engine oil is not continuous, and unnecessary loss of the engine oil can be prevented during the maintenance of the slewing bearing.

[0022] 3. The present invention compresses the engine oil by bringing the pressure plate and the anti-leakage plate together, allowing the engine oil to flow quickly under pressure, so that the engine oil can be sprayed onto the steel balls in the slewing bearing, and the debris in the slewing bearing and the previous engine oil are flushed, so that the previous engine oil and debris can be moved away from the slewing bearing more conveniently. The pressure plate passes through the constraint bar and reaches the left side of the constraint bar. Because the longitudinal span of the anti-leakage plate is greater than the distance between the two constraint bars, the anti-leakage plate is separated from the pressure plate under the obstruction of the constraint bar, allowing the pressure plate and the anti-leakage plate to move to the initial position, and the pressure plate and the anti-leakage plate are separated so as to refill the slewing bearing with engine oil.

[0023] 4. The present invention is located below the steel ball on the slewing bearing through the guide channel, so that the oil previously mixed with oil and debris in the slewing bearing can flow into the guide channel, so that the previous oil and debris are cleaned. A plurality of through-ports arranged in a circle are reserved on the lower wall of the guide channel. Under the guidance of the guide channel, the oil previously mixed with oil and debris flows to one of the through-ports, and the previous oil and debris flow out through the through-ports, so that the previous oil and debris are cleaned.

[0024] 5. The present invention attracts magnet 1 and magnet 2 to each other, so that magnet 1 does not move, ensuring that the slewing bearing cannot pull the decontamination sheet 1 to rotate together when rotating, and guides the previous engine oil adhering to the outer wall of the inner ring of the slewing bearing. The decontamination sheet 1 is provided with a plurality of wedge-shaped openings 1, and the previous engine oil is guided through the wedge-shaped openings 1, so that the previous engine oil flows into the guide channel through the wedge-shaped openings 1.

[0025] 6. The present invention can pull the second cleaning sheet to rotate on the outer ring of the slewing bearing through the rotation of the inner ring of the slewing bearing. A plurality of wedge-shaped openings are reserved on the outer wall of the second cleaning sheet. The oil on the outer ring of the slewing bearing is guided through the second wedge-shaped openings so that the oil on the outer ring of the slewing bearing can flow to the guide channel through the second wedge-shaped openings. A plurality of magnets are fixedly connected to the inner wall of the outer ring of the slewing bearing. The polarity of the second magnet and the first magnet facing each other is opposite. When the inner ring of the slewing bearing rotates, the second cleaning sheet rotates along with the inner ring of the slewing bearing. The second cleaning sheet cleans the outer ring of the slewing bearing while the first cleaning sheet does not rotate along with the slewing bearing. The first cleaning sheet cleans the inner ring of the slewing bearing, thereby improving the removal effect of the previous oil.

[0026] 7. The present invention collects the oil flowing out of the through-port 1 through the annular collecting cover and discharges it to the meshing part of the worm and the worm wheel through the oil discharge nozzle, thereby maintaining the meshing part of the worm and the worm wheel.

[0027] 8. The overall maintenance of the present invention is very convenient and can be completed without disassembling the slewing bearing, which greatly improves the convenience of maintenance.

[0044] An operating table 10 is also installed on the bracket 1. The operating table 10 is located below the hydraulic rod 3. A storage chamber 103 is reserved in the middle of the upper end of the operating table 10. The engine oil is filled into the storage chamber 103. A barrier sheet 102 fixedly connected to the operating table 10 is reserved at the upper end of the storage chamber 103. The barrier sheet 102 blocks external debris to prevent the debris from falling into the storage chamber 103, which causes more impurities in the engine oil in the storage chamber 103. The operating table 10 is screwed with a support column 101. A concrete pavement imitation plate 18 is installed on the upper end of the support column 101. A slewing bearing 104 is installed on the outer wall of the lower end of the support column 101. The lower end of the support column 101 extends downward and passes through the operating table 10, and the outer wall of the lower end of the support column 101 is fixedly connected to the inner ring of the slewing bearing 104, and the outer ring of the slewing bearing 104 is fixedly connected to the operating table 10. The bottom of the support column 101 is screwed with a steel ball 16, and the inner side of the bracket 1 is laterally fixedly connected to the support plate 15. The upper wall surface of the support plate 15 is in contact with the outer wall surface of the steel ball 16, and is fixedly connected to the support column 101 through the inner ring of the slewing bearing 104, and the lower end of the outer ring of the slewing bearing 104 is fixedly connected to the operating table 10, so that the support column 101 is fixedly connected to the operating table 1 0 is more convenient to rotate, and a liquid injection unit 12 is installed at the upper end of the slewing bearing 104. The liquid injection unit 12 is used to transport the engine oil in the storage chamber 103 to the steel ball in the slewing bearing 104. The liquid injection unit 12 includes a liquid injection channel 121 connected to the outer ring of the slewing bearing 104 and the operating table 10 at both ends. The engine oil in the slewing bearing 104 is transported to the steel ball in the slewing bearing 104 through the liquid injection channel 121, making it more convenient for the slewing bearing 104 to transport the engine oil. At the same time, the transportation mechanism can remove the debris that falls into the steel ball in the slewing bearing 104, and the engine oil with some debris remaining in it is renewed. The slewing bearing 1 The steel balls of 04 rotate continuously, and can perform maintenance and decontamination on the steel balls in various positions. When the steel balls change, they can pull the adhered engine oil to various positions, and can perform decontamination and maintenance on the ring that constrains the steel balls in the slewing bearing 104, making the maintenance of the entire slewing bearing 104 more convenient. The injection channel 121 passes through the side wall of the storage chamber 103 at one end close to the operating desktop 10 and extends into the storage chamber 103. A guide port 1041 is reserved inside the outer ring of the slewing bearing 104, and the engine oil is guided through the guide port 1041 so that the engine oil can accurately flow to the steel balls in the slewing bearing 104, making the maintenance of the slewing bearing 104 more convenient.

[0045] Reference Figure 3 , Figure 5-7The upper wall surface of the inner ring of the slewing bearing 104 is above the upper wall surface of the outer ring thereof. The inner ring of the slewing bearing 104 is located above the outer ring, so that the rotating ring 122 is fixedly connected to the inner ring of the slewing bearing 104 and the outer ring of the slewing bearing 104 can rotate normally. The injection unit 12 also includes a rotating ring 122. The inner wall surface of the rotating ring 122 is fixedly connected to the support column 101 by a connecting strip 1221. When the support column 101 rotates, the support column 101 pulls the inner ring of the slewing bearing 104 to rotate. The slewing bearing 104 and the rotating ring 122 are fixedly connected via the connecting strip 1221. When the slewing bearing 104 rotates, the rotating ring 122 can be pulled to rotate outside the slewing bearing 104. The upper end of the injection channel 121 is movably provided with a movable sheet 1 23. An inclined opening 1231 is reserved on the upper wall surface of the movable sheet 123. An extension sheet 1222 is fixedly connected to the outer wall of the rotating ring 122. When the rotating ring 122 rotates, the extension sheet 1222 can be pulled to change. A pressing sheet 1223 is fixedly connected to the lower wall surface of the extension sheet 1222. When the extension sheet 1222 rotates along with the rotating ring 122, the pressing sheet 1223 at the lower end of the extension sheet 1222 rotates along with the extension sheet 1222. During the rotation of the pressing sheet 1223, it extends into the inside of the inclined opening 1231 and presses the wall surface of the inclined opening 1231, so that the movable sheet 123 is pressed and changes toward the direction of the slewing bearing 104. The inside of the injection channel 121 is screwed with the constraint sheet 124. The upper end of the constraint sheet 124 is fixedly connected to the injection channel. The rotating piece 1241 at the upper end of 121 is pressed by the movable piece 123, and the lower end of the movable piece 123 close to the rotating piece 1241 is reserved with a storage chamber 1234. The storage chamber 1234 is flush with the outlet ends of the rotating piece 1241 and the movable piece 123, so that when the movable piece 123 presses the rotating piece 1241, the rotating piece 1241 can pull the constraint piece 124 to rotate. After the movable piece 123 is pulled to change again, the constraint piece 124 and the rotating piece 1241 are located inside the storage chamber 1234. The spiral beryllium copper wire 1242 is fixedly connected between the rotating piece 1241 and the injection channel 121. One end of the spiral beryllium copper wire 1242 rotates circumferentially under the action of external force. At this time A circumferential force will be generated. When the external force is removed, the circumferential reset will be performed under the circumferential force of the spiral beryllium copper wire 1242. After the movable piece 123 moves away, the constraint piece 124 and the rotating piece 1241 move to the initial position under the cooperation of the spiral beryllium copper wire 1242. After the constraint piece 124 rotates, the constraint piece 124 will not block the injection channel 121, so that the engine oil flows through the constraint piece 124 to the tail of the injection channel 121. The lower end of the injection channel 121 close to the side of the slewing bearing 104 is reserved with a drain port 1212. The engine oil passes through the drain port 1212 and the guide port 1041, making it more convenient for the engine oil to maintain the slewing bearing 104. The filling of the engine oil is not continuous. During the maintenance of the slewing bearing 104,Can prevent unnecessary loss of engine oil.

[0046] Reference Figure 7 The upper end of the injection channel 121 is fixedly connected to the spiral beryllium copper wire 1232. The spiral beryllium copper wire 1232 is axially compressed when subjected to external force. When the external force is removed, the spiral beryllium copper wire 1232 can automatically return to the axial direction under the deformation of the spiral beryllium copper wire 1232. The other end of the spiral beryllium copper wire 1232 is fixedly connected to the movable sheet 123. When the movable sheet 123 changes under the cooperation of the compression sheet 1223, the protrusion of the movable sheet 123 compresses the spiral beryllium copper wire 1232, so that the spiral beryllium copper wire 1232 is compressed. When the compression sheet 1223 is tilted, the spiral beryllium copper wire 1232 is compressed. After the opening 1231 moves away, the movable sheet 123 moves to the initial position with the cooperation of the spiral beryllium copper wire 1232. After the movable sheet 123 moves away, the rotating sheet 1241 leaves from the inside of the storage chamber 1234. The storage chamber 1234 will not block the rotating sheet 1241. The rotating sheet 1241 moves to the initial position with the cooperation of the spiral beryllium copper wire 1242 to facilitate the operation of the injection unit 12. After the rotating sheet 1241 rotates and comes into the inside of the storage chamber 1234, the rotating sheet 1241 blocks the storage chamber 1234 to prevent the oil from leaking out.

[0047] Reference Figure 7 and Figure 8The lower wall surface of the movable sheet 123 is fixedly connected with a protrusion 1233. The movable sheet 123 is moved to pull the protrusion 1233 to move inside the injection channel 121. The left side of the lower end of the protrusion 1233 is fixedly connected with a pressure sheet 125. The movement of the protrusion 1233 can pull the pressure sheet 125 to move inside the injection channel 121. The right side of the pressure sheet 125 is movably provided with a leakproof sheet 1251. After the pressure sheet 125 is moved, it is closed with the leakproof sheet 1251. The movable push leakproof sheet 1251 moves inside the injection channel 121, and the pressure sheet 125 and the leakproof sheet 1251 are brought together to compress the engine oil, so that the engine oil is compressed and flows quickly, so that the engine oil can be sprayed onto the steel ball in the slewing bearing 104, and the debris in the slewing bearing 104 and the previous engine oil are flushed, so that the previous engine oil and debris can be moved away from the slewing bearing 104 more conveniently. The pressure sheet 125 and the leakproof sheet 1251 are both provided with a through opening 1252, and the through opening 1252 on the pressure sheet 125 The second opening 1252 and the through opening 1252 on the leakproof sheet 1251 are staggered with each other, so that the engine oil passes through the pressure sheet 125 and the leakproof sheet 1251 through the through opening 1252, and then reaches the pressure sheet 125 and the second constraint sheet 124. The two longitudinal side walls inside the injection channel 121 are fixedly connected to the constraint strip 1211. The longitudinal span of the leakproof sheet 1251 is greater than the longitudinal span of the pressure sheet 125. After the protrusion 1233 pulls the pressure sheet 125 to change to the initial position, the pressure sheet 125 passes through about The tie strip 1211 reaches the left side of the constraint strip 1211. Since the longitudinal span of the leakproof sheet 1251 is greater than the distance between the two constraint strips 1211, the leakproof sheet 1251 is separated from the pressure sheet 125 under the obstruction of the constraint strip 1211, so that the pressure sheet 125 and the leakproof sheet 1251 are moved to their initial positions. The pressure sheet 125 and the leakproof sheet 1251 are separated so as to refill the slewing bearing 104 with engine oil. The previous engine oil is the engine oil that has been used for some time and is accompanied by foreign matter.

[0048] Reference Figure 5 , Figure 6 , Figure 9-11 A guide channel 105 is reserved on the lower wall surface of the space inside the operating desktop 10 and under the steel ball on the slewing bearing 104. The cross-section of the guide channel 105 is circular. Through the guide channel 105, it is located under the steel ball on the slewing bearing 104, so that the oil previously mixed with oil and debris in the slewing bearing 104 can flow into the guide channel 105, so that the previous oil and debris can be cleaned. A plurality of through ports 1051 arranged in a circle are reserved on the lower wall surface of the guide channel 105. Under the guidance of the guide channel 105, the oil previously mixed with oil and debris flows to the through port 1051, and the previous oil and debris flow outward through the through port 1051, so that the previous oil and debris can be cleaned.

[0049] Reference Figure 5 , Figure 6 , Figure 9-11 The lower end of the inner ring of the slewing bearing 104 is located above its outer ring. A decontamination unit 11 is installed inside the slewing bearing 104. The decontamination unit 11 includes a decontamination sheet 111 movably connected to the outer wall of the inner ring of the slewing bearing 104. The magnet 1111 and the magnet 2 1121 are attracted to each other so that the magnet 1111 will not move, ensuring that the slewing bearing 104 cannot pull the decontamination sheet 111 to rotate together when rotating, and guide the previous engine oil adhering to the outer wall of the inner ring of the slewing bearing 104. A plurality of wedge-shaped openings 1112 are reserved on the decontamination sheet 111, and the previous engine oil is guided through the wedge-shaped openings 1112, so that the previous engine oil flows into the guide channel 105 through the wedge-shaped openings 1112, and a plurality of magnets 1111 are fixedly connected to the outer wall of the decontamination sheet 111.

[0050] Reference Figure 5 , Figure 6 , Figure 9-11 A second decontamination sheet 112 is arranged on the inner wall surface of the outer ring of the slewing bearing 104. The second decontamination sheet 112 is fixedly connected to a connecting sheet 1122 toward the inside of the slewing bearing 104. The connecting sheet 1122 is used to connect the inner ring of the slewing bearing 104 with the second decontamination sheet 112. The outer wall of the second decontamination sheet 112 and the inner wall surface of the outer ring of the slewing bearing 104 are in close contact with each other. The rotation of the inner ring of the slewing bearing 104 can pull the second decontamination sheet 112 to rotate on the outer ring of the slewing bearing 104. A plurality of wedge-shaped openings 1123 are reserved on the outer wall of the second decontamination sheet 112. The oil before the oil on the outer ring of the slewing bearing 104 is cleaned by the second wedge-shaped openings 1123. The oil on the outer ring of the slewing bearing 104 is guided to flow to the guide channel 105 through the wedge-shaped opening 1123. A plurality of magnets 1121 are fixedly connected to the inner wall surface of the outer ring of the slewing bearing 104. The polarity of the magnet 1121 and the opposite side of the magnet 1111 are opposite, so that when the inner ring of the slewing bearing 104 rotates, the cleaning piece 112 rotates along with the inner ring of the slewing bearing 104, and the cleaning piece 112 cleans the outer ring of the slewing bearing 104, while the cleaning piece 111 does not rotate along with the slewing bearing 104, and the cleaning piece 111 cleans the inner ring of the slewing bearing 104, thereby improving the removal effect of the previous oil.

[0051] Reference Figure 3A driving unit 14 is also installed on the inner side of the bracket 1. The driving unit 14 includes a second motor 141 fixedly connected to the outer side of the bracket 1, a worm 142 screwed on the inner wall of the bracket 1, and a worm wheel 143 fixedly connected to the outer wall of the lower end of the support column 101. One end of the worm 142 is connected to the output end of the second motor 141, and the worm 142 and the worm wheel 143 are engaged with each other. The second motor 141 pulls the worm 142 to rotate, and the worm 142 pulls the worm wheel 143 to rotate, which in turn pulls the concrete pavement imitation plate 18 on the support column 101 to rotate, and the concrete pavement imitation plate 18 applies lateral force to the tire, thereby being able to more realistically simulate the use status of the tire in the real environment.

[0052] Refer to 3 and Figure 4 The annular collecting cover 13 is fixedly connected to the lower wall of the operating table 10 and below the through-port 1051. The two sides of the lower end of the annular collecting cover 13 are connected to the slanted oil discharge nozzles 131, and the oil discharge nozzles 131 are directly facing the bite of the worm 142 and the worm wheel 143. The oil flowing out of the through-port 1051 is collected by the annular collecting cover 13 and discharged to the bite of the worm 142 and the worm wheel 143 through the oil discharge nozzles 131, so as to maintain the bite of the worm 142 and the worm wheel 143.

[0053] Reference Figure 3 A collecting box 17 is placed on the inner side of the bracket 1, and the collecting box 17 is located below the meshing position of the worm 142 and the worm wheel 143. The oil falling from the meshing position of the worm 142 and the worm wheel 143 is collected through the collecting box 17, which is convenient for recycling the wasted oil.

[0054] The specific implementation method is as follows: during the pressure test, the tire is assembled on the connecting shaft 9, and the tire is supported by the concrete road imitation plate 18. The hydraulic rod 3 drives the detachable pressure plate 4 to descend and apply pressure to the tire. When the tire is subjected to a puncture test, the detachable pressure plate 4 is removed and replaced with a test cone. The tire is subjected to a puncture test according to the above steps through the test cone. When the tire is subjected to a wear test, the tire driver 8 drives the tire to rotate, and the motor 6 drives the screw rod 19 to rotate, so that the chassis 7 rises and falls, thereby driving the wheel The tire driver 8 moves to move the tire installed on the connecting shaft 9, so as to adjust the friction between the tire and the concrete pavement imitation plate 18. The motor 141 pulls the worm 142 to rotate, and the worm 142 drives the worm wheel 143 to rotate, thereby rotating the support column 101, and the support column 101 drives the concrete pavement imitation plate 18 to rotate. The concrete pavement imitation plate 18 applies a lateral force to the tire, thereby more realistically simulating the use state of the tire in the real environment, improving the accuracy of detection, and realizing the detection of the tire;

[0055] During the test, when the slewing bearing 104 rotates, the slewing bearing 104 pulls the compression piece 1223 through the skewed opening 1231, and the skewed opening 1231 pulls the restraining strip 1211 and the leakproof sheet 1251 together to compress the oil in the injection channel 121. The restraining piece 124 rotates under the pressure of the movable piece 123 on the rotating piece 1241. After the restraining piece 124 rotates, the oil can pass through the restraining piece 124 and reach the drain port 1212. The oil refuels the slewing bearing 104 through the guide port 1041, and the debris and the previous oil in the slewing bearing 104 are washed away. The oil flows to the guide channel 105 along the wall of the slewing bearing 104, and then flows to the through channel 105 through the guide channel 105. The oil flows out through the through-port 1051 and then flows to the outside through the through-port 1051. When the inner ring of the slewing bearing 104 rotates, the cleaning piece 112 rotates with the inner ring of the slewing bearing 104, and the cleaning piece 112 cleans the outer ring of the slewing bearing 104. The cleaning piece 111 cannot rotate with the slewing bearing 104, and the cleaning piece 111 cleans the inner ring of the slewing bearing 104. The outflowing engine oil is collected from the through-port 1051 through the annular collecting cover 13, and is discharged to the bite of the worm 142 and the worm wheel 143 through the oil discharge nozzle 131, and the bite of the worm 142 and the worm wheel 143 is maintained, and finally falls into the collection box 17 to recover the wasted oil, which is convenient for the maintenance of the device.
