Detailed Implementation

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Example

[0043] See Figures 1 to 5As shown, a movable spindle tire changer includes a base 1, a column 2 fixed on the base, and a tire changing assembly 3 on the column. A guide slider 4 is fixed on the base, and an adjusting support 5 is provided on the base. A guide rail 6 is fixed on the bottom surface of the adjusting support. The guide rail is slidably disposed within the guide slider. In this embodiment, the base and column are conventional structures of the prior art, and are simply applied, so they are not described in detail. The top surface of the guide slider is provided with an inverted T-shaped or dovetail-shaped groove, and the cross-section of the guide rail is I-shaped or dovetail-shaped. The guide rail is slidably disposed within the guide slider, which can ensure the effectiveness and reliability of the translation.

[0044] Furthermore, in this embodiment, a positioning block 7 is fixed to the side of the column, and a control cylinder 8 is fixed to the side of the adjusting support. The piston shaft of the control cylinder is fixed to the positioning block. The control cylinder is a conventional structure in the prior art. When in use, the control cylinder extends and retracts, driving the guide slide rail to move horizontally on the guide slider, and causing the adjusting support to move closer to or away from the column. This enables the adjusting support to perform horizontal adjustment operations.

[0045] Furthermore, a rotary motor 9 is fixed to the bottom of the adjusting support, and a hollow support column 10 is fixed to the top of the adjusting support. A tire fixing plate 11 is arranged above the hollow support column, and a shaft 12 is integrally formed in the center of the tire fixing plate. A connecting sleeve 13 connected to the rotary motor is arranged inside the hollow support column, and the upper part of the connecting sleeve extends out of the top surface of the hollow support column. The shaft is inserted into the connecting sleeve and locked and positioned by a locking screw. With the above structure, the lifting and lowering adjustment of the tire fixing plate can be realized, and the normal rotation operation of the tire fixing plate can also be guaranteed.

[0046] Its lifting and adjusting mechanism is mainly used in conjunction with the tire loading and unloading carrier. When the tire loading and unloading carrier is raised, in order to facilitate the transfer of the tire to the tire fixing plate, the tire fixing plate is lowered so that it is lower than the tire loading and unloading carrier. Then, the tire is manually pushed to the top of the tire fixing plate, and then the tire fixing plate is raised and inserted into the tire. This ensures the effectiveness and convenience of tire assembly, reduces the labor intensity of workers, especially for very heavy tires, and improves the stability and reliability of tire lifting.

[0047] In this embodiment, a support housing 14 is fixed to the end face of the adjusting support away from the column, and a lifting cylinder 15 is fixed inside the support housing; a tire loading and unloading carrier 16 is fixed to the piston shaft at the top of the lifting cylinder; when the lifting cylinder rises, the tire is delivered to the tire fixing plate via the tire loading and unloading carrier; when the lifting cylinder lowers, the tire loading and unloading carrier completes the tire unloading operation. Both the support housing and the lifting cylinder are conventional structures in the prior art, simply applied, mainly for tire lifting and pushing operations.

[0048] In practical applications, the tire loading and unloading support frame includes a tire support frame 161, an L-shaped tire loading and unloading frame 162, an L-shaped rocker arm 163, and a support rod 164. The L-shaped rocker arm is mainly used to drive the L-shaped tire loading and unloading frame to rotate during lifting and lowering, while the tire support frame is mainly used to move the tire to the tire fixing plate position.

[0049] During assembly, the corner of the L-shaped rocker arm is rotatably connected to the end of the tire carrier frame via a first pin 17, and the transverse bar of the L-shaped rocker arm is attached to the side of the tire carrier frame; the top of the vertical bar of the L-shaped tire loading and unloading frame is fixed to the bottom of the vertical part of the L-shaped rocker arm via a screw; the top of the support rod is rotatably connected to the end of the transverse bar of the L-shaped rocker arm via a second pin 18, and the bottom of the support rod is rotatably connected to the upper part of the side wall of the support housing via a third pin 19; the piston shaft of the lifting cylinder is fixed to the end of the tire carrier frame near the L-shaped rocker arm; when the lifting cylinder rises, the L-shaped rocker arm drives the L-shaped tire loading and unloading frame to rotate, so that the vertical part of the L-shaped tire loading and unloading frame is on the same horizontal plane as the tire carrier frame.

[0050] Its working principle is as follows: the lifting cylinder descends, and the horizontal part of the L-shaped tire loading and unloading frame touches the ground. At this time, the tire is rolled onto the horizontal part of the L-shaped tire loading and unloading frame. Then, the lifting cylinder rises, and the L-shaped rocker arm, in conjunction with the support rod, moves, causing the L-shaped tire loading and unloading frame to rotate 90 degrees counterclockwise. At this time, the original vertical part of the L-shaped tire loading and unloading frame becomes the horizontal part and is on the same horizontal plane as the tire carrier frame. At this time, the tire is placed upside down on the original vertical part of the L-shaped tire loading and unloading frame. The tire fixing plate is lowered so that it is lower than the top surface of the tire carrier frame. At this time, the tire is manually pushed from the L-shaped tire loading and unloading frame to the tire carrier frame. Then, the tire fixing plate is raised, which completes the installation and positioning of the tire and the tire fixing plate. The rotary motor is started, and the tire removal component is used to complete the tire removal operation.

[0051] After tire maintenance, lower the tire retainer and push the tire onto the L-shaped tire loading and unloading rack. Then, lower the lifting cylinder to allow the tire to fall back to the ground and roll.

[0052] In this embodiment, guide rollers 20 are fixed on the tire carrier and the vertical portion of the L-shaped tire loading and unloading frame to facilitate tire movement. This improves the smoothness and effectiveness of tire pushing and reduces the labor intensity of workers. The edges of the guide rollers protrude from the surfaces of the vertical portion of the tire carrier and the L-shaped tire loading and unloading frame.

[0053] In this embodiment, a clearance area 21 is provided in the middle of the tire support frame; the hollow support column passes through the clearance area. This ensures the lifting and lowering of the tire mounting plate and also ensures the center connection between the tire mounting plate and the tire.

[0054] In this embodiment, a plurality of foot switches 22 are provided on the side of the base, and a control switch platform 23 is provided on the column. This enables convenient operation, and both are conventional structures of the prior art, simply applied. The foot switches can realize the rotation control of the rotary motor, and can also realize the lifting adjustment control of the lifting cylinder.

[0055] In this embodiment, the tire removal assembly includes an adjusting cylinder 31, a lifting seat 32, a tire-scraping arm 33, a tire-removing shovel 34, and a three-function tool head 35. During assembly, the adjusting cylinder is fixed to the base and located inside the column; the lifting seat is disposed in the vertical groove of the column and fixedly connected to the piston shaft of the adjusting cylinder; the tire-scraping arm is oscillating on the lifting seat via a vertical axis, and the tire-removing shovel is fixed to the tire-scraping arm; the three-function tool head is disposed on the front of the lifting seat. The lifting seat, tire-scraping arm, and tire-removing shovel are all conventional structures of the prior art, simply applied, and therefore not described in detail.

[0056] Furthermore, the three-function tool head includes a C-shaped tool base 351 and a tool body 353 rotatably connected to the C-shaped tool base via a connecting shaft 352. Three tool heads 354 with different functions are fixed at equal intervals along the edge of the tool body. During assembly, the C-shaped tool base has circular holes, a disc is fixed to the connecting shaft, and the disc has three limiting holes. Limiting rods 355 are installed within the circular holes. When the tool body rotates on the C-shaped tool base, the limiting rods insert into the limiting holes for limitation. The tool head includes a tire loosening chisel, a tire removal head, and a tire mounting head. This allows for switching between different tool heads, improving ease of use, reducing the overall size and cost of the structure, simplifying operation, and ensuring stable and reliable use.

[0057] This utility model has positive effects: its structure is reasonably designed, with an adjustable support on the base, and in conjunction with a guide rail, guide slider, and control cylinder, the adjustable support can be adjusted horizontally, which facilitates tire installation and removal, improves tire loading and unloading efficiency, and the adjustable support is equipped with a rotary motor and a hollow support, and the shaft of the tire fixing plate can be lifted and inserted into the connecting bushing. This not only ensures the normal rotation of the tire fixing plate, but also allows for lifting and adjustment, making it easy to transfer tires from the tire loading and unloading carrier to the tire fixing plate or to remove them from the tire fixing plate, reducing the labor intensity of workers. Especially for heavy tires, it can also improve the stability and effectiveness of tire installation and removal, facilitate adjustment operations, and ensure stable and reliable use.

[0058] Moreover, its adjustable support, in conjunction with the lifting cylinder and tire loading and unloading support frame, facilitates the lifting, disassembly and transfer of tires, improves the effectiveness of tire lifting and disassembly, reduces the labor intensity of workers, and is stable and reliable in use.

[0059] Meanwhile, its tire removal components include an adjusting cylinder, a lifting seat, a tire-scraping arm, a tire-removing shovel, and a three-function tool head. The three-function tool head enables different tire removal and installation operations to meet the needs of different situations. Moreover, the operation is more convenient, which helps to reduce the weight and volume of the overall structure and expand its applicability.

[0060] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
