DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] When in use, the wide tire sleeve is placed on the outside of the positioning assembly using the lifting assembly and dropped until the rim passes through the sliding sleeve 6, so that the support plate extending from one side of the sliding sleeve 6 fits with the inner edge of the rim, thereby providing a reaction force to the rim during the process of lifting the rim, thereby better peeling and removing the wheel rim and the rim.

[0038] A hollow shaft 9 is provided at the top of the column 2, and a rotating shaft 10 is rotatably connected inside the hollow shaft 9. A first bevel gear 11 is fixedly installed on the top of the rotating shaft 10. A connecting rod 13 is rotatably installed above the rim limit block 3 through a connecting seat 15.

[0039] In this embodiment, a hollow shaft 9 is arranged on the top of the column 2, and a first bevel gear 11 and a fourth bevel gear 18 are respectively arranged on the top of the hollow shaft 9 and inside the hollow shaft 9. The first bevel gear 11 and the second bevel gear 12 are engaged to drive the first screw 7 to rotate, thereby changing the spacing between the fixed sleeve 5 and the sliding sleeve 6, so that the sliding sleeve 6 can be tightened against rims of different widths.

[0040] At the same time, the fourth bevel gear 18 and the fifth bevel gear 19 are meshed to drive the second screw 14 to rotate in the connecting seat 15. A second internally threaded sleeve 16 is provided in the connecting seat 15. Therefore, the second internally threaded sleeve 16 drives the connecting seat 15 to slide on the surface of the connecting rod 13, thereby driving the rim limit block 3 connected to the bottom of the connecting seat 15 to expand outward synchronously, so as to adapt to rims with different inner diameters, thereby further supporting and limiting the wide tire in the vertical direction.

[0041] The positioning assembly also includes a second screw 14, one end of the second screw 14 is rotatably connected to the fixed sleeve 5, and the other end of the second screw 14 is rotatably installed in the hollow shaft 9, and the second screw 14 is located in the hollow shaft 9.

A second internal threaded sleeve 16 is rotatably installed in the connecting seat 15, and the second screw 14 and the second internal threaded sleeve 16 are threadedly connected.

[0042] When in use, the rotation of the rotating shaft 10 drives the fourth bevel gear 18 to rotate, the fourth bevel gear 18 and the fifth bevel gear 19 are meshed, the fifth bevel gear 19 drives the second screw 14 to rotate, the second screw 14 is meshed with the second internal threaded sleeve 16, and the second internal threaded sleeve 16 is rotatably connected to the connecting seat 15 through a bearing. Therefore, the rotation of the fourth bevel gear 18 can drive the rim limit block 3 to follow the fixed sleeve 5 and slide along the connecting rod 13, so that the four groups of rim limit blocks 3 are tightened in the rim, and the sliding sleeve 6 is cooperated to limit and support the wide tire.

[0043] A pressing assembly for limiting the position during the wide-body tire removal process, the pressing assembly is symmetrically arranged outside the positioning assembly, and the pressing assembly includes a support plate 21 and a limiting wheel 20 rotatably mounted on one side of the support plate 21, and the limiting wheel 20 is arranged in contact with the tire bead sidewall during the wide-body tire removal process;

[0044] In this embodiment, a limiting wheel 20 is arranged to fit the upper side wall of the wheel rim. When the wheel rim is lifted, the wheel rim is pressed to prevent the wheel rim and the rim from moving synchronously, which is not conducive to the peeling and removal of the wheel rim and the rim.

[0045] A lifting rod 22 is threadedly connected to the bottom of the support plate 21 , a linear guide rail 23 is fixedly installed on the upper surface of the base 1 , and the bottom end of the lifting rod 22 is fixedly connected to a slider of the linear guide rail 23 .

[0046] In this embodiment, a linear guide rail 23 is provided on the base 1, and the linear guide rail 23 drives the lifting rod 22, the support plate 21 and the limiting wheel 20 in sequence to move horizontally outside the rim limiting block 3 to adapt to wide tires of different diameters;

[0047] At the same time, the height of the limiting wheel 20 is adjusted by rotating the lifting rod 22 to adapt to wide tires of different widths.

[0048] The pressing assembly can perform air blowing treatment on the wide-body tire. The limiting wheel 20 is arranged as a hollow tube structure. An air bag 32 is connected to one side of the limiting wheel 20. A mounting plate 33 is connected to one side of the support plate 21. The air bag 32 is fixedly mounted on the mounting plate 33. A hollow air pipe 24 is arranged through the limiting wheel 20. The air pipe 24 is connected to the air bag 32 through a hose 27. A first air hole 25 is opened in the air pipe 24, and a second air hole 26 is opened in the limiting wheel 20.

[0049] In this embodiment, a group of air bags 32 are installed on one side of the support plate 21 through the mounting plate 33. The air bags 32 are connected to the limiting wheel 20. The limiting wheel 20 is set to a hollow tube structure, and an air pipe 24 is passed through and rotatably connected to the limiting wheel 20. The air pipe 24 is connected to the hose 27. By squeezing the air bags 32, air is supplied to the inside of the limiting wheel 20. A second air hole 26 is opened in the limiting wheel 20, and a first air hole 25 is opened in the air pipe 24. Therefore, when the air bags 32 are squeezed, the air flow can be blown out to remove impurities on the wide tire, effectively avoiding the friction of impurities between the tool and the wide tire, and avoiding damage to the wide tire.

[0050] One end of the air pipe 24 is rotatably installed in the support plate 21, and an eccentric disk 29 is fixedly installed on one end of the air pipe 24, a shaft sleeve 28 is rotatably installed on one side of the eccentric disk 29, a connecting rod 30 is fixedly connected to the side wall of the shaft sleeve 28, and a connecting block 31 is pinned at one end of the connecting rod 30, and the connecting block 31 is fixedly installed on the upper surface of the airbag 32.

[0051] In this embodiment, air inlet valves are provided at the top and bottom of the airbag 32. When the airbag 32 is stretched, air enters and exits the airbag 32 through the air inlet valve. When the airbag 32 is compressed, the airflow enters the air pipe 24 through the hose 27, enters the limiting wheel 20 through the first air hole 25, and finally blows toward the surface of the wide tire through the second air hole 26.

[0052] A third internally threaded sleeve 36 is rotatably installed in one end of the top of the column 2, and a lifting rod 35 is connected to the internal thread of the third internally threaded sleeve 36. The top of the lifting rod 35 is rotatably connected to the hollow shaft 9. A motor 46 is installed on one side of the column 2. The motor 46 and the third internally threaded sleeve 36 are transmission connected. Specifically, a first gear 34 is fixedly installed on the output shaft end of the motor 46, and a large gear ring 37 is fixedly installed on the surface of the third internally threaded sleeve 36. The first gear 34 and the large gear ring 37 are meshing.

[0053] In this embodiment, a lifting rod 35 is provided, and the starting motor 46 drives the first gear 34, the first gear 34 and the large gear ring 37 to rotate, and the large gear ring 37 drives the third internal threaded sleeve 36 to rotate in the column 2, thereby driving the lifting rod 35 to move in the vertical direction, lifting the rim, so that the wheel rim and the wheel rim can be peeled off and removed for easy replacement.

[0054] A support frame 43 is fixedly installed on the outer wall of the column 2, and two groups of fixed seats 45 are fixedly connected to the support frame 43. The second gear 38 and the third gear 39 are rotatably installed in one group of the fixed seats 45, and the second gear 38 is meshed with the large gear ring 37. Two groups of fourth gears 40 are meshed on one side of the third gear 39, and a fifth gear 41 is meshed on one side of the fourth gear 40. A fourth internally threaded sleeve 44 is rotatably installed in the support frame 43, and the third screw 42 is connected to the inner thread of the fourth internally threaded sleeve 44, and the stripping wheel 4 is movably connected to the top of the third screw 42.

[0055] In this embodiment, two sets of bead stripping discs 4 are symmetrically arranged on the surface of the column 2. When the wide tire is set on the outside of the rim limit block 3 and pressed down, the bead stripping discs 4 can be inserted into the gap between the rim and the wheel rim. When the rim is lifted, the bead stripping discs 4 are used to apply downward force to the rim, which is convenient for removal.

[0056] Furthermore, a fixing seat 45 is provided on one side of the support frame 43 for supporting the ring stripping wheel 4, in which the second gear 38 and the third gear 39 are rotatably connected respectively, the second gear 38 is meshed with the large gear ring 37, the third gear 39 is meshed with the fifth gear 41 through two sets of fourth gears 40, the rotation of the fifth gear 41 drives the fourth internal threaded sleeve 44 to rotate, the fourth internal threaded sleeve 44 is threadedly connected to the third screw 42, the ring stripping wheel 4 is universally connected to the top of the third screw 42, therefore, in the process of lifting the rim, the large gear ring 37 rotates, driving the second gear 38 and the third gear 39 to rotate, the third gear 39 is transmitted to the fifth gear 41 through the two sets of fourth gears 40, so that the third screw 42 and the second gear 38 rotate in opposite directions, therefore, when the lifting rod 35 drives the rim limit block 3 to rise, the third screw 42 drives the ring stripping wheel 4 to descend, further accelerating the stripping and removal efficiency of the rim and the wheel rim.

[0057] Working principle: The new energy wide-body tire to be replaced is hoisted by the lifting assembly, and the wide-body tire sleeve is set on the outside of the positioning assembly by the lifting assembly, and falls until the rim passes through the sliding sleeve 6, so that the support plate extending from one side of the sliding sleeve 6 fits with the inner edge of the rim, and the rotating shaft 10 rotates through the first bevel gear 11 and the second bevel gear 12. The second bevel gear 12 is also fixedly installed on the top of the first screw rod 7. The two sets of second bevel gears 12 are meshed, so the first screw rod 7 can be driven to rotate, and the spacing between the fixed sleeve 5 and the sliding sleeve 6 is changed, so that the above-mentioned sliding sleeve 6 can be tightened against rims of different widths;

[0058] The fourth bevel gear 18 is meshed with the fifth bevel gear 19, and the rotation of the rotating shaft 10 drives the fourth bevel gear 18 to rotate, driving the second screw 14 to rotate in the connecting seat 15. The connecting seat 15 is provided with a second internal thread sleeve 16, so the second internal thread sleeve 16 drives the connecting seat 15 to slide on the surface of the linkage rod 13, thereby driving the rim limit block 3 connected to the bottom of the connecting seat 15 to expand outward synchronously, so as to adapt to rims with different inner diameters, thereby further supporting and limiting the wide tire in the vertical direction;

[0059] After releasing the lifting assembly, the linear guide rail 23 is started to drive the limiting wheel 20 to approach the wide tire until the limiting wheel 20 and the sidewall of the wide tire are in contact, and it is ensured that the limiting wheel 20 does not touch the rim;

[0060] The starter motor 46 drives the first gear 34, the first gear 34 and the large gear ring 37 rotate, and the large gear ring 37 drives the third internal thread sleeve 36 to rotate in the column 2, thereby driving the lifting rod 35 to move in the vertical direction to lift the rim, so that the wheel rim and the wheel rim are peeled off and removed for easy replacement;

[0061] Two sets of bead stripping discs 4 are symmetrically arranged on the surface of the column 2. When the wide tire is sleeved on the outside of the rim limit block 3 and pressed down, the bead stripping discs 4 can be inserted into the gap between the rim and the wheel rim. When the rim is lifted up, the bead stripping discs 4 are used to apply downward force to the rim, so as to facilitate removal.

[0062] When the lifting rod 35 drives the rim stopper 3 to rise, the third screw rod 42 drives the ring stripping wheel disc 4 to descend, further accelerating the stripping and removal efficiency of the rim and wheel rim;

[0063] During the jacking process, the wheel rim is rotated to facilitate the peeling of the wheel rim. During the rotation of the wheel rim, the limiting wheel 20 is driven to rotate, thereby driving the air pipe 24 to rotate. Since the air pipe 24 is avoided to be provided with an eccentric disk 29, a shaft sleeve 28 and a connecting rod 30 connected to one side of the shaft sleeve 28 are pinned on one side of the eccentric disk 29. Therefore, during the rotation of the eccentric disk 29, the connecting rod 30 can stretch and compress the air bag 32. Inlet valves are provided at the top and bottom of the air bag 32. When the air bag 32 is stretched, air enters and exits the air bag 32 through the intake valve. When the air bag 32 is compressed, the airflow enters the air pipe 24 through the hose 27, enters the limiting wheel 20 through the first air hole 25, and finally blows to the surface of the wide tire through the second air hole 26, effectively avoiding the friction of impurities between the tool and the wide tire, and avoiding damage to the wide tire.
