[0002] Tire removal and installation are common and crucial steps in bus maintenance. Traditional tire lug nuts removal tools are mostly manual wrenches or fixed electric wrenches. Manual wrenches are inefficient and require significant physical exertion from maintenance personnel, especially when dealing with bus tire lug nuts, which are large and require high tightening torque, making manual operation difficult and time-consuming. While fixed electric wrenches improve efficiency to some extent, their fixed position makes them unsuitable for bus tires of varying heights. This necessitates frequent adjustments to posture or the use of other tools, which is extremely inconvenient and severely impacts the efficiency and quality of maintenance work. Furthermore, the tire removal and installation machine needs frequent movement within the maintenance area to work on different tire positions. Traditional machines either lack convenient moving mechanisms or are not flexible and stable enough to meet actual maintenance needs. Utility Model Content

The bottom end of the lifting rod is connected to the top end of the hydraulic rod by a threaded connection to transmit power and realize the lifting action.

[0008] Preferably, a spring is connected to the bottom end of the hydraulic rod. One end of the spring is sleeved on the bottom end of the hydraulic rod and welded and fixed. The hydraulic rod is connected to the pedal through a connecting rod. When the pedal is stepped down, the pedal rotates around its connecting shaft with the device and drives the hydraulic rod to extend upward through the connecting rod, thereby supporting the lifting rod and making the support plate and electric wrench rise synchronously. This achieves precise lifting of the electric wrench to meet the needs of removing bus tire bolts at different heights.

[0009] Compared with existing technologies, the advantages of this utility model are as follows: its height can be precisely adjusted through the cooperation of hydraulic rods, pedals, and springs, making it easy to adapt to different tire heights and improving maintenance efficiency; the universal wheels of the base ensure flexible movement and a stable connection, facilitating convenient operation in the maintenance site; the double-layer structure of the support plate with rubber pads can buffer vibration, protect components, and stabilize the operation of the electric wrench; the reasonable connection method between each component ensures structural stability; the design of the sliding belt and handrail makes the vertical movement of the electric wrench smooth and convenient to operate.

[0015] 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.

[0016] Please see Figures 1 to 3 This utility model presents a technical solution:

[0017] A height-adjustable mobile tire bolt removal and installation machine for passenger vehicles mainly consists of a base 1, a support plate 2, a handrail 3, an electric wrench 4, a sliding belt 5, a bracket 6, a foot bar 7, a caster wheel 8, a hydraulic rod 9, a spring 10, a lifting rod 11, a sliding groove 12, and a rubber pad 13.

[0018] In one preferred embodiment of this invention, casters 8 are installed at the four lower corners of the base 1, and are secured to the base 1 with screws, allowing the entire device to move easily. The upper part of the base 1 is fixedly connected to the bracket 6 by welding, thus completing the bottom structure of this invention and providing a stable support foundation for other components of the device.

[0019] In one preferred embodiment of this invention, the support plate 2 is designed as a two-layer structure. A rubber pad 13 is placed between the two layers of the support plate 2, and the rubber pad 13 is glued to the upper and lower support plates 2. During use, when the device vibrates, the rubber pad 13 can effectively absorb and reduce the vibration transmitted from the support plate 2 due to its elastic properties, preventing damage to the base 1 and the lifting rod 11, thus providing protection. A sliding belt 5 is installed on the top of the support plate 2, and the sliding belt 5 is tightly fitted to the support plate 2 through a slot. The electric wrench 4 is fixed to the sliding belt 5 of the support plate 2 by a special clamp. The smooth surface of the sliding belt 5 enables the electric wrench 4 to move vertically, facilitating the disassembly of bus tire bolts at different heights.

[0020] In one preferred embodiment of this invention, the lifting rod 11 is located in the middle of the structure. Its upper end is connected to the support plate 2 via a flange, while its lower end is welded to the bracket 6. The side of the lifting rod 11 closest to the handrail 3 is embedded in the slide groove 12, forming a sliding fit. The slide groove 12 restricts and guides the movement of the lifting rod 11, ensuring the smoothness of its lifting process. The bottom end of the lifting rod 11 is connected to the top end of the hydraulic rod 9 via a threaded connection to transmit power and achieve the lifting action.

[0021] In one preferred embodiment of this invention, a spring 10 is connected to the bottom end of the hydraulic rod 9. One end of the spring 10 is fitted onto the bottom end of the hydraulic rod 9 and welded in place. The hydraulic rod 9 is connected to the pedal 7 via a connecting rod. When the user steps down on the pedal 7, the pedal 7 rotates around its connecting shaft to the device, causing the hydraulic rod 9 to extend upwards via the connecting rod, thereby supporting the lifting rod 11. This causes the support plate 2 and the electric wrench 4 connected to the lifting rod 11 to rise synchronously, achieving the effect of precisely lifting the electric wrench 4. This adapts to the needs of removing tire bolts from buses at different heights, improving the practicality and ease of operation of the device.

[0022] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
