Detailed Implementation

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-5This utility model discloses a multi-type wheeled equipment tire mounting and dismounting platform, comprising: a support plate 1; a connecting rod 2 between two support plates 1, which connects the two support plates 1 into a whole, enhancing the stability of the structure and providing a basic framework for the installation of subsequent components; first connecting threaded rods 3 fixedly connected to both ends of the connecting rod 2, which are used to connect and fix the connecting rod 2 to the support plate 1, serving as the connection medium between the connecting rod 2 and the support plate 1; and a connecting nut 4 threadedly connected to the outer surface of the first connecting threaded rod 3, which, through thread engagement with the first connecting threaded rod 3, tightly fixes the first connecting threaded rod 3 to the support plate 1, preventing loosening between the connecting rod 2 and the support plate 1. A rotary bearing 10 is rolled onto the upper surface of plate 1. The rotary bearing 10 reduces the friction between the second connecting threaded rod 8 and the support plate 1 during rotation, making the rotation of the second connecting threaded rod 8 smoother. The second connecting threaded rod 8 is sleeved on the inner surface of the rotary bearing 10. The second connecting threaded rod 8 is mounted on the support plate 1 via the rotary bearing 10 and can rotate around the central axis of the rotary bearing 10, providing support for adjusting the position of the support rod 7. Two adjusting nuts 9 are threaded onto the outer surface of the second connecting threaded rod 8. The two adjusting nuts 9 are located on the left and right sides of the rotary bearing 10, respectively. By engaging with the threaded parts of the second connecting threaded rod 8, the position of the second connecting threaded rod 8 on the rotary bearing 10 can be fixed, thereby fixing the angle and position of the support rod 7. One end of the second connecting threaded rod 8 is fixedly connected to a support rod 7. The support rod 7 is mounted on the support plate 1 via the second connecting threaded rod 8 to support the tire and, together with other components, to achieve stable tire placement. Fixing posts 18 are fixedly connected to both sides of the rear surface of the support rod 7. The fixing posts 18 are located between the two support rods 7, enhancing the connection stability between the two support rods 7 and also providing a certain degree of limit to the tire, preventing it from swaying left and right on the support rods 7. A pry bar 5 is provided on the front surface of the support plate 1. The pry bar 5 can pry the tire using the lever principle. Together with the abutment post 11 and other components, it facilitates tire removal. A handle 6 is fixedly connected to the upper surface of the pry bar 5, providing a gripping point for the operator to easily operate the pry bar. 5. To make the prying action of the crowbar 5 less strenuous, a contact post 11 is fixedly connected to the lower surface of the crowbar 5. When the crowbar 5 pries, the contact post 11 contacts the tire or other components, transmitting the force of the crowbar 5 to the tire, thus prying the tire. A fixing sleeve 12 is fixedly connected to the front surface of the crowbar 5. The fixing sleeve 12 provides an installation position for the positioning screw 13, allowing the positioning screw 13 to be stably installed on the crowbar 5. The fixing sleeve 12 is detachably connected to the positioning screw 13 via a tightening nut 14. The tightening nut 14 cooperates with the fixing sleeve 12 and the positioning screw 13 to fix the position of the positioning screw 13 within the fixing sleeve 12, while also facilitating the removal and adjustment of the positioning screw 13. A mounting bracket 15 is fixedly connected to the lower surface of the positioning screw 13.Mounting bracket 15 is used to mount positioning post 16, connecting positioning post 16 to positioning screw 13 to achieve force transmission. Positioning post 16 is fixedly connected to the inner surface of mounting bracket 15. Positioning post 16 provides a rotation axis for limiting rod 17, allowing limiting rod 17 to rotate around positioning post 16, facilitating adjustment of the position of limiting rod 17. Limiting rod 17 is rotatably connected to the outer surface of positioning post 16. Limiting rod 17 abuts against the outer surface of pry bar 5, limiting the rotation angle of pry bar 5, preventing excessive rotation of pry bar 5, and ensuring operational stability.

[0024] The first connecting threaded rod 3 extends to the outer wall of the support plate 1, allowing the connecting nut 4 to abut against the outer wall of the support plate 1, thereby fixing the first connecting threaded rod 3 to the support plate 1 and ensuring a firm connection between the connecting rod 2 and the support plate 1. The abutment between the connecting nut 4 and the outer wall of the support plate 1, through the threaded action of the connecting nut 4 and the first connecting threaded rod 3, tightly fixes the connecting rod 2 between the two support plates 1, enhancing the stability of the overall structure. The support rod 7 is located between the two second connecting threaded rods 8, which provide support for the support rod 7, enabling it to stably bear the weight of the tire. Adjusting nuts 9 are symmetrically arranged on the left and right sides of the outer surface of the rotating bearing 10. By adjusting the adjusting nuts 9 on the left and right sides, the position of the second connecting threaded rod 8 on the rotating bearing 10 can be fixed, thereby adjusting the angle and height of the support rod 7 to adapt to the installation requirements of different tires. The dimensions of the support rod 7 and the connecting rod 2 are compatible, ensuring that the support rod 7 and the connecting rod 2 can structurally cooperate to form a stable support frame, providing a convenient way for tire placement and removal. Providing reliable support, the fixing post 18 is located between the two support rods 7, strengthening the connection between the two support rods 7 and making the support rods 7 more stable when supporting the tire, preventing deformation or displacement of the support rods 7. The limiting rod 17 abuts against the outer surface of the pry bar 5, limiting the rotation of the pry bar 5 and ensuring that the pry bar 5 operates within a reasonable angle range, improving the safety and accuracy of tire removal. The positioning screw 13 is slidably connected to the inner surface of the fixing sleeve 12, allowing the positioning screw 13 to slide up and down within the fixing sleeve 12 for easy adjustment. The positions of the mounting bracket 15 and the limiting rod 17 are adapted to different operational needs. The mounting bracket 15 is located below the tightening nut 14, allowing the tightening nut 14 to apply downward pressure to the positioning screw 13, fixing the positioning screw 13 inside the fixing sleeve 12. At the same time, the mounting bracket 15 will not affect the tightening operation of the tightening nut 14. The size of the limiting rod 17 is matched with the size of the mounting bracket 15, ensuring that the limiting rod 17 can rotate smoothly around the positioning post 16 inside the mounting bracket 15, and the limiting function will not be affected by the size mismatch.

[0025] Working principle: First, connect the two support plates 1 via connecting rods 2, extending the first connecting threaded rod 3 to the outer wall of the support plate 1. Use connecting nuts 4 to abut against the outer wall of the support plate 1, tightening the connecting rod 2 and the support plate 1 to form a stable frame. Rotate the second connecting threaded rod 8 (which is rolledly connected to the support plate 1 via a rotating bearing 10) to adjust the support rod 7 to a suitable angle. Then, fix the position of the second connecting threaded rod 8 using adjusting nuts 9 symmetrically positioned on the left and right sides of the outer surface of the rotating bearing 10. Use the support rod 7 to support the tire, and use the fixing post 18 (located between the two support rods 7) to assist in limiting the tire's position. Slide the positioning screw 13 into the fixing sleeve 12 on the front surface of the pry bar 5, adjust it to a suitable position, and then use... Tighten nut 14 to fix the mounting bracket 15 (located below nut 14), positioning post 16, and limiting rod 17 in their respective working positions. Limiting rod 17 abuts against the outer surface of pry bar 5 to limit its rotation angle. Hold handle 6 of pry bar 5 and make contact post 11 abut against the tire. Use leverage to pry the tire. The limiting rod 17 ensures stable operation. With the support of support rod 7, tire removal is completed. Place the tire on support rod 7 and use rotating bearing 10 to move the tire along the guide rail to the installation position. Use pry bar 5 to adjust the tire position to complete the installation. Loosen connecting nut 4 and nut 14, disassemble all parts, and store the platform components according to regulations for easy carrying and future use.
