[0013] Compared with the prior art, the present invention provides a heavy-duty tire puncture resistance test device, which has the following beneficial effects:

[0014] 1. A heavy-duty tire puncture resistance test device, by starting an electric push rod, pushes two sets of fixed plates two apart, and under the connection of a first tooth column, the two sets of fixed plates one are brought close to each other, and the tire sample to be tested is clamped and loaded. After the first gear and the tooth plate are meshed with each other, the fixed plate one and the fixed plate two are turned upside down. When the test is completed and returned to the original position, the electric push rod is started again to bring the two sets of fixed plates two close to each other, and the next set of tire samples to be tested can be clamped and loaded. At the same time, the two sets of fixed plates one located at the lower side are separated to make the tire sample that has finished the test fall off, that is, the upper and lower loading and unloading of the tire during the puncture test is completed at the same time, saving manpower operation and improving work efficiency.

[0015] 2.

[0016] 3. This heavy-duty tire puncture resistance test device can simulate the phenomenon that the tire is punctured when going uphill when the moving component with the support box rolls on the magnetic plate and contacts the nails. Then when the moving component with the support box moves back, the tire sample rolls on the magnetic plate to simulate the phenomenon that the tire is punctured when going downhill. Through puncture tests on various road conditions such as uphill and downhill, the test effect can be made more realistic and accurate.

[0017] 4. In this heavy-duty tire puncture resistance test device, when the moving component rolls back through the support plate with the tire sample after the puncture test, the gap on the inner side can pull out the nails on the tire sample, which is convenient for the staff to check the puncture condition of the tread and can also prevent the staff from being accidentally injured by the nails.

[0035] Specifically, the nails and the magnetic plate 17 are attracted to each other through magnetism, and the magnetic plate 17 can absorb and fix the nails, but will not affect the movement of the nails following the tire after being inserted into the tire. Then, when the tire sample 3 moves back and passes through the support plate 14, the gap 15 opened on the inner side thereof can pull out the nails that may exist on the tire sample 3, and collect the pulled out nails into the collection box 13.

A second clamping block 820 is provided at the rear end of the second spring 819, and the second clamping block 820 fits with the clamping groove 87.

[0039] Specifically, during the process of the two sets of fixing plates 817 flipping to the upper side, the second clamping block 820, under the connection of the second spring 819, will move into the inner side of the second groove 818 when squeezed by the arc plate 85, and then the second clamping block 820 will come to the clamping groove 87 as the flipping proceeds, and then will be clamped into the inner side of the clamping groove 87 by the force of the second spring 819 to be fixed, so as to prevent the connecting mechanism 8 from shaking when carrying the tire sample 3 for testing, and the first clamping block 813 is the same as above.

[0040] In this embodiment, the opposite sides of the two groups of fixed plates 817 are rotatably connected to the second rotating plate 821, and the opposite sides of the two groups of second rotating plates 821 are fixedly connected to the connecting tube 822. The lower end of the support box 81 is provided with two groups of symmetrical electric push rods 823, and the output end of the electric push rod 823 is fixedly connected to the fixed plate 817.

[0041] Specifically, the electric push rod 823 is started again to retract the two sets of fixing plates 817 to be close to each other, and then moved into the inner side of the next set of tire samples 3 to be tested through the connecting tube 822 to connect them, and the two sets of fixing plates 810 on the lower side will be separated, so that the connecting tube 815 is moved out from the inner side of the tire sample 3.

[0042] In this embodiment, the moving component 9 includes a motor 91, a connecting frame 92 is fixedly connected to the outer side of the motor 91, a slider 93 is fixedly connected to the front end of the connecting frame 92, and the slider 93 is slidably connected to the inner side of the third slide groove 6.

The front end of the second gear 94 is fixedly connected to a rotating block 95, and the outer side of the rotating block 95 is rotatably connected to a connecting block 96. The connecting block 96 is slidably connected to the inner side of the second slide groove 5, and the front end of the connecting block 96 passes through the second slide groove 5 and is fixedly connected to the connecting plate 84.

[0043] Specifically, the motor 91 is started, and the motor 91 causes the second gear 94 to rotate clockwise, and the second gear 94 meshes with the tooth plate 7. At the same time, the second gear 94 rolls on the tooth plate 7 under the connection of the slider 2 93, and then drives the connecting mechanism 8 to start moving under the connection of the connecting block 96. The connection of the rotating block 95 prevents the connecting mechanism 8 from turning over when the second gear 94 rotates.

[0044] In this embodiment, the auxiliary component 10 includes an installation box 101, a first connecting groove 102 is opened on the inner side of the installation box 101, and a second gear column 103 is rotatably connected to the inner side of the first connecting groove 102, the lower end of the second gear column 103 is meshed with a gear rod 104, the gear rod 104 is slidably connected to the installation box 101, the rear end of the gear rod 104 passes through the main board 22 and is slidably connected to the main board 22, the upper end of the second gear column 103 is meshed with a gear plate 4 105, the gear plate 4 105 is slidably connected to the installation box 101, the rear end of the gear plate 4 105 is fixedly connected to a gear plate 5 106, the gear plate 5 106 is meshed with the first gear 82, a support ear 107 is fixedly connected to one side of the gear plate 4 105, and the rear end of the support ear 107 is fixedly connected to an inclined plate 108.

[0045] Specifically, when the moving component 9 drives the connecting mechanism 8 to move toward the arc slope 16, the first gear 82 will mesh with the tooth plate five 106, causing the support box 81 to flip over. At this time, the two sets of fixed plates 810 clamping the tire sample 3 will flip to the lower side, and the tire sample 3 will also contact the support plate 14. Then, when the moving component 9 continues to move with the support box 81, the first gear 82 and the front end of the support box 81 will contact the inclined plate 108. Under the action of the push of the support box 81, one side of the inclined plate 108 drives the tooth plate five 106 to slide forward, and under the connection of the second tooth column 103, the gear rod 104 moves backward.

[0046] In this embodiment, a connecting slope 19 is fixedly connected to one side of the connecting seat 11, two groups of partitions 20 are arranged at the upper end of the connecting slope 19, a recovery pool 21 is arranged on one side of the connecting slope 19, a feed chamber 22 is fixedly connected to the front end of the main board 1, a feed port 23 is fixedly connected to the upper end of the feed chamber 22, and an opening and closing plate 24 is movably connected to the other side of the feed chamber 22 through a spring.

[0047] Specifically, after the tire sample 3 after the puncture test is removed from the connecting mechanism 8, it will automatically roll into the recovery pool 21 under the connection of the connecting slope 19, and the staff will check the puncture resistance. After the first group of tire samples 3 placed in the feed chamber 22 is clamped away, the next group of tires cached in the feed chamber 22 will fall down and wait to be clamped for the puncture test.

[0048] When in use, the tire sample 3 to be tested is placed in the feed cavity 22, and the nails in the nail storage box 18 are made to fall onto the magnetic plate 17, and then the electric push rod 823 is started. The two groups of electric push rods 823 push the fixed plate 2 817 to move forward and backward respectively. The fixed plate 2 817 at the front end will contact the gear rod 104 in the process of moving forward, and push the gear rod 104 to move forward and mesh with the second gear column 103, thereby prompting the gear plate 4 105 to drive the gear plate 5 106 and the inclined plate 108 to move backward. At the same time, when the electric push rod 823 pushes the fixed plate 2 817 to move, the gear plate 3 816 moves simultaneously with the fixed plate 2 817, and meshes with the first gear column 88, thereby prompting the gear plate 2 89 to drive the fixed plate 1 810 to move in the opposite direction. The two sets of fixing plates 810 are moved to the inner side of the tire sample 3 at the same time, and the two sets of connecting tubes 815 are moved to the inner side of the tire sample 3 at the same time, and cooperate with the first rotating plate 814 to connect the tire sample 3. Then, the motor 91 is started, and the motor 91 causes the second gear 94 to rotate clockwise, so that the second gear 94 rolls on the tooth plate 7, and then drives the connecting mechanism 8 to start moving under the connection of the connecting block 96. During the process of the moving component 9 driving the connecting mechanism 8 to move toward the arc slope 16, the first gear 82 is meshed with the tooth plate 5 106, so that the supporting box 81 is turned over. At this time, the two sets of fixing plates 810 clamping the tire sample 3 are turned over to the lower side, and the tire sample 3 is also in contact with the supporting plate 14. In addition, the two sets of fixing plates 817 are also turned over to the upper side at the same time, and the tire sample 3 is also in contact with the supporting plate 14. During the flipping process, the second clamping block 820 is clamped into the inner side of the clamping slot 87 by the force of the second spring 819 for fixing. Then, when the moving component 9 continues to move with the support box 81, one side of the inclined plate 108 is pushed by the support box 81, so that the inclined plate 108 drives the tooth plate 5 106 to slide forward, and then, under the connection of the second tooth column 103, the tooth bar 104 moves backward. Next, the moving component 9 drives the connecting mechanism 8 to move, so that the tire sample 3 rolls onto the magnetic plate 17 to simulate an uphill climb. During the process, the tread of the tire sample 3 will contact the nails, and some nails will penetrate into the tire sample 3. After the tire sample 3 moves to the upper end of the magnetic plate 17, the nail storage box 18 uses the induction switch to make the nails fall onto the magnetic plate 17 again, and then the motor 91 The reverse output causes the second gear 94 to rotate counterclockwise, causing the tire sample 3 to roll down through the magnetic plate 17, simulating the effect of being punctured by nails when going downhill. The fixed plate 1 810 drives the tire sample 3 to continue rolling back, and then the motor 91 drives the support box 81 back to the original position. At this time, the fixed plate 2 817 is located on the upper side, and then the electric push rod 823 is started again to recover the two groups of fixed plates 2 817 to be close to each other, and then the connecting tube 2 822 is moved into the inner side of the next group of tire samples 3 to be tested to connect them, and the two groups of fixed plates 1 810 on the lower side will separate, so that the connecting tube 1 815 is moved out from the inner side of the tire sample 3, and under the connection of the connecting slope 19, the tire sample 3 will automatically roll into the recovery pool 21, and the staff will check the puncture resistance.And the fixing plate 1 810 will push the gear rod 104 forward again during the process of separation and movement, and the steps are as above, and the above operations are repeated to perform the puncture resistance test on the next group of tire samples 3.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
