DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, reference Figures 1 to 4 , which is the first embodiment of the present invention, provides a giant tire special repair tool, comprising:

[0033] The support mechanism 100 includes a guide rail frame 101, a slider 102 slidably disposed in the guide rail frame 101, and a guide wheel 103 disposed on the guide rail frame 101; a limiting groove 101a is defined in the guide rail frame 101, and the slider 102 is slidably disposed in the limiting groove 101a.

[0034] The fixing mechanism 200 includes a fixing plate 201 disposed on the slider 102, and an arc-shaped groove 201a disposed on the fixing plate 201. The fixing plate 201 is provided with a pusher 202, and the pusher end of the pusher 202 is movably connected to a connecting arm 203, and the end of the connecting arm 203 is movably connected to a movable wheel 204; the outer wall of the movable wheel 204 is slidably connected to the inner wall of the arc-shaped groove 201a;

[0035] The connecting arm 203 can be pushed to move by the push piece 202, so that the connecting arm 203 pushes the movable wheel 204 to slide in the arc groove 201a.

[0036] It also includes an electric winch 300 arranged on the guide rail frame 101 , and the sling on the electric winch 300 is connected to the fixed plate 201 .

[0037] The connecting arm 203 is pushed by the push piece 202 to move, so that the two movable wheels 204 are moved closer to or away from each other. When in use, the giant tire is placed horizontally on the ground, and the electric winch 300 is used to lower the sling to make the fixed plate 201 descend. When the fixed plate 201 descends, the sling continues to be lowered, which will cause the fixed plate 201 to rotate until the two movable wheels 204 in a state of approaching each other are inserted into the middle of the giant tire. Then, the connecting arm 203 is pushed by the push piece 202, so that the movable wheels 204 slide on the inner wall of the arc groove 201a, so that the two movable wheels 204 are moved away from each other and expand, and fit on the inner wall of the giant tire to form a support. After the fixation is completed, the sling is rolled up by the electric winch 300, so that the fixed plate 201 is deflected first, and then the slider 102 is pulled to slide and rise together in the guide frame 101. The tire placement height can be adjusted according to the winding distance of the electric winch 300, which is convenient for fixing and lifting the giant tire, and thus convenient for operators to perform maintenance.

[0038] In addition, when fixing the tire, there is another fixing method, which is to stand the tire upright and clamp the two sides of the tire respectively through two movable wheels 204 to achieve clamping and limiting of the tire.

[0039] Example 2, reference Figure 1 to Figure 4, which is the second embodiment of the present invention. Different from the previous embodiment, the push member 202 includes a limit rail 202a arranged on the fixed disk 201, and a threaded block 202b slidably arranged in the limit rail 202a, and also includes a screw rod 202c threadedly connected to the threaded block 202b, and one end of the screw rod 202c is provided with a first driving motor 202d; the threaded block 202b is rotatably connected to the connecting arm 203, and the rotation of the screw rod 202c is controlled by the first driving motor 202d, so that the threaded block 202b can slide in the limit rail 202a, and the threaded block 202b will push the connecting arm 203 to move when sliding, and a relative rotation is generated between the connecting arm 203 and the threaded block 202b, so that the connecting arm 203 pushes the movable wheel 204 to slide in the arc groove 201a, thereby realizing the control of the two movable wheels 204.

[0040] A connecting shaft 201 b is provided on the fixing plate 201 , and a notch 201 c is provided on the connecting shaft 201 b ; two symmetrically arranged notches 201 c are provided at the end of the connecting shaft 201 b .

[0041] The slider 102 is provided with a lower slide groove 102a and a narrow slide groove 102b, the lower slide groove 102a and the narrow slide groove 102b are connected, the short diameter of the connecting shaft 201b with a notch 201c is the same as the width of the narrow slide groove 102b, and the long diameter of the connecting shaft 201b is the same as the width of the lower slide groove 102a.

[0042] A hook 201d is provided on the fixed plate 201; a clamping groove 102c is provided on the slider 102, and the outer wall of the hook 201d is movably connected to the clamping groove 102c.

[0043] The guide frame 101 is provided with a front support leg 101b and a rear support leg 101c. There are two front support legs 101b, which are symmetrically arranged. The arrangement of the front support legs 101b and the rear support legs 101c can improve the stability of the support of the guide frame 101. Since the giant tire is fixed on one side of the guide frame 101, the center of gravity will change. The longer front support leg 101b can further improve the stability and keep the center of gravity of the device stable after the giant tire is fixed.

[0044] The rest of the structure is the same as that of Example 1.

[0045] In the initial state, refer to Figure 2 The connecting shaft 201b is located in the narrow slide groove 102b, and the hook 201d is stuck in the clamping groove 102c. At this time, due to the joint action of the notch 201c on the connecting shaft 201b and the hook 201d, the fixed plate 201 and the slider 102 are kept in a parallel state. When the sling is wound by the electric winch 300, the slider 102 and the fixed plate 201 will be driven to rise and fall.

[0046] When fixing the tire, the sling is first lowered by the electric winch 300. Under the action of gravity, since the bottom end of the slider 102 first contacts and fits with the guide rail frame 101, lowering the sling will cause slippage between the fixed plate 201 and the slider 102, and the hook 201d slides down, and the connecting shaft 201b slides down until the connecting shaft 201b slides into the lower groove 102a. Since the diameter of the lower groove 102a is the same as that of the connecting shaft 201b, the connecting shaft 201b can rotate. Therefore, when the sling is lowered, the fixed plate 201 will deflect until the fixed plate 201 is in a horizontal state, and the movable wheel 204 enters the middle of the giant tire.

[0047] The movable wheel 204 is controlled by the push piece 202 to clamp the giant tire, and then the sling is rolled up by the electric winch 300. When the connecting shaft 201b is located in the lower slide groove 102a, the fixed plate 201 is in an inclined state and rises until the connecting shaft 201b moves to the connection between the lower slide groove 102a and the narrow slide groove 102b. It should be noted that the slider 102 has a certain weight and also has a counterweight function when hoisting to increase the stability of the device. At the same time, since the slider 102 has a certain counterweight, the narrow slide groove 102 b has a small diameter, so the connecting shaft 201b in an inclined state cannot enter the narrow slide groove 102b. Only when the notch 201c is aligned with the two sides of the narrow slide groove 102b, the connecting shaft 201b can enter the narrow slide groove 102b. Therefore, when the sling is pulled up, the fixed plate 201 will be deflected first until the fixed plate 201 is in a vertical state. At this time, the pulling up of the sling will make the fixed plate 201 rise vertically, so that the hook 201d is stuck in the clamping groove 102c. Therefore, after the giant tire is stood up, the fixed plate 201 has better stability.

[0048] Example 3, reference Figure 1 to Figure 4 , which is the third embodiment of the present invention, is different from the previous embodiment in that a driving wheel 207 is provided on the fixed disk 201.

[0049] Specifically, a second driving motor 205 is disposed on the fixed disk 201 , and the second driving motor 205 is used to drive the driving wheel 207 to rotate.

[0050] Furthermore, a fixed arm 206 is provided on the second driving motor 205 , and the second driving motor 205 is connected to the driving wheel 207 via the fixed arm 206 .

[0051] The second driving motor 205 is connected to the driving wheel 207 via a transmission chain, and the transmission chain is placed inside the fixed arm 206 to realize the rotation of the driving wheel 207 .

[0052] The second driving motor 205 is rotatably mounted on the fixed plate 201 .

[0053] The fixed plate 201 is provided with a third driving motor 208 , and the third driving motor 208 is used to drive the second driving motor 205 to rotate.

[0054] The third driving motor 208 can be used to control the rotation of the fixed arm 206 , thereby changing the position of the driving wheel 207 .

[0055] The rest of the structure is the same as that of Example 2.

[0056] Although the expansion change of the two movable wheels 204 can realize the fixation of the giant tire, the two-point fixation method has a poor fixation effect. Therefore, when fixing, it can be fixed in conjunction with the driving wheel 207. The following three fixing methods can be used:

[0057] First, two movable wheels 204 and a driving wheel 207 are set at the center of the giant tire. The two movable wheels 204 are expanded and the position of the driving wheel 207 is changed by rotating the fixed arm 206 to fix the tire. In this state, the giant tire can be rotated by rotating the driving wheel 207.

[0058] Secondly, the driving wheel 207 is arranged in the middle of the giant tire, and the two movable wheels 204 are arranged outside the giant tire. The three cooperate to clamp the contour of the giant tire. In this state, the giant tire can be rotated by rotating the driving wheel 207.

[0059] Thirdly, the driving wheel 207 is arranged outside the giant tire, and the two movable wheels 204 are arranged in the middle of the giant tire. The three cooperate to clamp the contour of the giant tire. In this state, the giant tire can be rotated by rotating the driving wheel 207.

[0060] With the above three fixing methods, the device can be applied to giant tires of different sizes and specifications, thereby improving the applicable scope of the device and the fixing effect, and facilitating the repair work on the inside and outside of the tire. It should be noted that the driving wheel 207 is provided with a middle rubber wheel 207a and a side groove 207b. The setting of the side groove 207b facilitates the fit with the inner edge of the tire, thereby improving the friction and the fixing effect. The setting of the middle rubber wheel 207a facilitates the fit between the driving wheel 207 and the outer surface of the giant tire, thereby facilitating the control of the rotation of the tire.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
