Description

Technical Field

[0001] This utility model relates to the technical field of tire installation, and in particular to a tire installation auxiliary frame. Background Technology

[0002] Currently, the common method for assembling or disassembling vehicle wheels is to first use a jack to lift the vehicle before assembling or disassembling the wheels. After the vehicle is lifted to a certain height, the tires need to be lifted to the corresponding installation height, a time-consuming and labor-intensive process. Furthermore, when installing tires on large vehicles, the size and weight of these tires make lifting them more difficult, increasing the labor intensity. While there are existing devices to assist in tire lifting, they lack a structure to limit tire movement, which can cause the tire to wobble during lifting and affect the efficiency of subsequent tire assembly. Utility Model Content

[0003] To address the above shortcomings, this utility model proposes a tire mounting auxiliary frame. The tire is held together by upper and lower adjustable limiting plates and mounting frame. This not only adapts to the installation of tires of different thicknesses, but also helps to reduce the shaking that occurs when the tire is lifted, thereby improving the tire assembly efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A tire mounting auxiliary frame includes: a frame, a lifting frame movably mounted on the frame in a vertical direction, the lifting frame being connected to a drive mechanism, and a mounting frame movably mounted on the lifting frame in a horizontal direction. The mounting frame includes a first adjusting rod and a second adjusting rod spaced apart in a vertical direction. Locking structures are provided between the mounting frame and the first adjusting rod, and between the mounting frame and the second adjusting rod. The locking structures are used to lock the position of the first adjusting rod or the second adjusting rod after it has moved in the horizontal direction. One end of each of the first adjusting rod and the second adjusting rod is threadedly connected to a limiting plate, and the limiting plate and the mounting frame together clamp the tire.

[0005] Furthermore, the mounting bracket includes two opposing first vertical rods, each first vertical rod having a first horizontal rod connected to its lower end, each first horizontal rod having a first mounting groove, each first mounting groove having a first adjusting rod slidably mounted thereon, a connecting rod being provided between the two first adjusting rods, and the limiting plate defining a clamping space for accommodating the tire between itself and the first vertical rod.

[0006] Furthermore, the locking structure includes a plurality of first mounting holes, which are arranged along the same straight line on one of the first crossbars. The corresponding first adjusting rod is provided with a second mounting hole, and one of the first mounting holes and the second mounting hole are connected by a first pin.

[0007] Furthermore, a second vertical rod is provided at the upper end of each of the first vertical rods, a second horizontal rod is connected between the two second vertical rods, a through hole is provided in the middle of the second horizontal rod, the second adjusting rod is slidably disposed with the through hole, and the locking structure is provided between the second horizontal rod and the second adjusting rod.

[0008] Furthermore, a second mounting groove is provided at the upper end of the first vertical rod, and a second vertical rod is slidably disposed in each of the second mounting grooves, wherein the locking structure is provided between one of the first vertical rods and the corresponding second vertical rod.

[0009] Furthermore, the frame is provided with a guide rod in the vertical direction, the drive mechanism includes a motor provided on the frame, the output end of the motor is connected to a screw, the screw is arranged parallel to the guide rod, and the lifting frame includes two parallel sliders, one of which is threadedly connected to the screw, and the other slider is slidably arranged with the guide rod.

[0010] Furthermore, a third crossbar is connected between the two sliders, and a fourth crossbar is connected to the upper part of each of the first vertical bars.

[0022] See Figures 1 to 3 A tire mounting auxiliary frame includes: a frame 100, a lifting frame 110 movably mounted on the frame 100 in the vertical direction, the lifting frame 110 being connected to a drive mechanism, and a mounting frame 200 movably mounted on the lifting frame 110 in the horizontal direction. The mounting frame 200 includes a first adjusting rod 210 and a second adjusting rod 220 spaced apart in the vertical direction. Locking structures are provided between the mounting frame 200 and the first adjusting rod 210, and between the mounting frame 200 and the second adjusting rod 220. The locking structures are used to lock the position of the first adjusting rod 210 or the second adjusting rod 220 after it has moved in the horizontal direction. One end of the first adjusting rod 210 and the second adjusting rod 220 is threadedly connected to a limiting plate 230. The limiting plate 230 and the mounting frame 200 together clamp the tire.

[0023] In use, the tire mounting auxiliary frame with the above structure first adjusts the positions of the first adjusting rod 210 and the second adjusting rod 220 according to the tire thickness, thereby initially adjusting the distance between the limiting plate 230 and the tire. A locking structure is then used to lock the position of the first adjusting rod 210 or the second adjusting rod 220 after horizontal movement. The tire is then placed between the corresponding limiting plate 230 and the mounting frame 200. The limiting plate 230 is then rotated to further adjust its position, ensuring it abuts against the tire. The multiple limiting plates 230 and the mounting frame 200 together clamp the tire, reducing subsequent tire lifting or movement sway. After the tire is placed, the drive mechanism moves the lifting frame 110 vertically, raising the tire to the corresponding installation height. Then, the mounting frame 200 is moved horizontally to bring the tire closer to the assembly area. Finally, the limiting plate 230 is rotated, removing its restriction on the tire and facilitating subsequent tire installation.

[0024] See Figures 1 to 3 Furthermore, the mounting bracket 200 includes two opposing first vertical rods 201, each first vertical rod 201 having a first horizontal rod 202 connected to its lower end. Each first horizontal rod 202 has a first mounting groove, and each first mounting groove has a first adjusting rod 210 slidably mounted thereon. A connecting rod 211 is provided between the two first adjusting rods 210, and a clamping space for accommodating the tire is defined between the limiting plate 230 and the first vertical rods 201. Specifically, the tire is placed on the two first horizontal rods 202, and the positions of the two first adjusting rods 210 are adjusted synchronously to accommodate tires of different thicknesses, thereby improving the applicability of the device. It is understood that the limiting plate 230 is connected to a mounting shaft 231, one end of which is threadedly connected to either the first adjusting rod 210 or the second adjusting rod 220, thus facilitating the rotation of the limiting plate 230.

[0025] See Figures 1 to 3 Furthermore, the locking structure includes multiple first mounting holes 120, which are arranged along the same straight line on one of the first crossbars 202. A corresponding first adjusting rod 210 is provided with a second mounting hole, and one of the first mounting holes 120 and the second mounting hole are connected by a first pin 121. Specifically, when the position of the first adjusting rod 210 needs to be adjusted, the first pin 121 is first removed, allowing the corresponding first adjusting rod 210 to move relative to the first mounting groove. This allows the other first adjusting rod 210 to move synchronously via a connecting rod. Finally, after the first adjusting rod 210 moves to the appropriate position, the first pin 121 is inserted into the corresponding second mounting hole and the first mounting hole 120, thereby quickly locking the position of the first adjusting rod 210 after movement using an insertion method. In some embodiments, the first mounting hole 120 and the second mounting hole can be threaded holes, and the first pin 121 can be replaced by a bolt rod that mates with the threaded hole, thereby improving the stability of the first adjusting rod 210 installation.

[0026] See Figures 1 to 3Furthermore, each first vertical rod 201 has a second vertical rod 203 at its upper end, and a second horizontal rod 204 connects the two second vertical rods 203. A through hole is provided in the middle of the second horizontal rod 204, and a second adjusting rod 220 is slidably disposed with respect to the through hole. A locking structure is provided between the second horizontal rod 204 and the second adjusting rod 220. Specifically, the locking structures provided between the second horizontal rod 204 and the second adjusting rod 220, and between the first horizontal rod 202 and the first adjusting rod 210, are similar or identical. It is understood that the locking structure includes multiple first insertion holes arranged horizontally on the second adjusting rod 220, and a second insertion hole on the second horizontal rod 204. One of the first insertion holes and the second insertion hole are connected by a first insertion rod, thereby enabling quick locking or disassembly of the second adjusting rod 220 using a plug-in method, which improves the convenience of adjusting the position of the second adjusting rod 220.

[0027] See Figures 1 to 3 Furthermore, a second mounting groove is provided at the upper end of the first vertical rod 201, and a second vertical rod 203 is slidably mounted in each second mounting groove. A locking structure is provided between one of the first vertical rods 201 and the corresponding second vertical rod 203. Specifically, the locking structures provided between the first vertical rod 201 and the second vertical rod 203, and between the first horizontal rod 202 and the first adjusting rod 210, are similar or identical. It can be understood that the locking structure includes multiple third insertion holes provided vertically in the first vertical rod 201, and a fourth insertion hole provided in the second vertical rod 203. One of the third insertion holes and the fourth insertion hole are connected by a second insertion rod, thereby using a plug-in method to quickly lock or remove the second vertical rod 203. This not only facilitates changing the position of the second vertical rod 203 in the vertical direction to adapt to tire insertion at different heights, but also improves the convenience of adjusting the position of the second vertical rod 203.

[0028] See Figure 1 and Figure 3 Furthermore, the frame 100 is provided with a guide rod 130 in the vertical direction. The drive mechanism includes a motor mounted on the frame 100, with a screw 140 connected to the output end of the motor. The screw 140 is arranged parallel to the guide rod 130. The lifting frame 110 includes two parallel sliders 111, one of which is threadedly connected to the screw 140, and the other slider 111 is slidably disposed with respect to the guide rod 130. Specifically, in use, the motor drives the screw 140 to rotate, causing one slider 111 to move vertically through the threaded action, while the other slider 111 restricts the rotation of the lifting frame 110, thereby enabling the lifting frame 110 to drive the tire to move vertically. It is understood that, in order to change the installation position of the motor, the output end of the motor and the lower end of the screw 140 transmit torque through a bevel gear assembly. In some embodiments, the drive mechanism may also be replaced by a hydraulic cylinder, which will not be described in detail here.

[0029] See Figure 1 and Figure 3 Furthermore, a third crossbar 112 connects the two sliders 111, and a fourth crossbar 205 is connected to the upper part of each first vertical bar 201. The third crossbar 112 has two guide holes along the horizontal direction, and each fourth crossbar 205 is slidably disposed with its corresponding guide hole, thus facilitating the movement of the third crossbar 112 and consequently driving the tire to move horizontally as a whole. It is understood that a fifth crossbar 207 connects the two fourth crossbars 205, facilitating the simultaneous movement of the two fourth crossbars 205.

[0030] See Figure 1 and Figure 3 Furthermore, one of the fourth crossbars 205 is provided with a third mounting hole, and the corresponding slider 111 is provided with a fourth mounting hole. The third mounting hole and the fourth mounting hole are connected by a second pin 150, so that the fourth crossbar 205 can be quickly locked or unlocked by plugging when the wheel 160 tire does not need to be moved in the horizontal direction.

[0031] See Figure 1 and Figure 3 Furthermore, one end of each of the two fourth horizontal bars 205 is connected to a third vertical bar 206, which makes it easier for people to push the fourth horizontal bars 205 to move via the third vertical bar 206.

[0032] See Figure 1 and Figure 3 Furthermore, the lower end of the frame 100 is provided with four rectangularly distributed casters 160, which facilitates the movement of the frame 100. In some embodiments, the casters 160 may also be replaced with existing casters with locking mechanisms, which allow people to lock the position of the frame 100 after it has been moved.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
