[0023] See also Figure 1As shown, mutually cooperating guide columns 132 and guide sleeves 131 are installed between the first mounting seat 1 and the second mounting seat 2, and multiple sets of support legs 111 are evenly distributed and fixedly installed on the bottom of the first mounting seat 1 and the second mounting seat 2. One end of the first mounting seat 1 and the second mounting seat 2 is close to the conveyor belt, and at least two sets of rotating wheels 141 are provided on the first mounting seat 1 and the second mounting seat 2 near one end of the conveyor belt. The rotating wheels 141 are movably connected to both sides of one end near the conveyor belt by a rotating shaft 142.

[0024] Furthermore, at least four groups of transmission wheel groups are evenly installed on the upper surfaces of the first mounting seat 1 and the second mounting seat 2. The transmission wheel group includes a transmission wheel frame 411, a guide column 416, an axle 412, a transmission wheel 413, a rubber block 415 and a spring 414. The transmission wheel group includes two groups of transmission wheel frames 411, and the bottom of the transmission wheel frame 411 is welded to the top surface of the first mounting seat 1. The guide columns 416 vertically penetrate the top of the transmission wheel frame 411 and the axle 412 and are fixedly connected to the top surface of the first mounting seat 1 at the bottom. The outer surface of the guide column 416 is provided with a spring 414 and is supported on the bottom surface of the axle 412 and the top surface of the first mounting seat 1. The two ends of the axle 412 are respectively penetrated by the two groups of guide columns 416. The outer surface of the axle 412 is installed with a transmission wheel 413, and the top of the first mounting seat 1 is provided with a strip groove 121 for the transmission wheel 413 to move downward near the bottom of the transmission wheel 413.

[0025] Furthermore, a rubber block 415 is glued to the top of the transmission wheel frame 411 .

[0026] See also Figure 1-2 As shown, a transmission wheel set and a strip groove 121 with the same structure and position are synchronously provided on the upper surface of the second mounting seat 2 .

[0027] Furthermore, the second mounting base 2 is welded to a support arm 3 on the side away from the first mounting base 1, the top of the support arm 3 is bolted to a cylinder 311, the output end of the cylinder 311 passes through the top of the support arm 3, and the output end of the cylinder 311 is fixedly connected to a clamping wheel assembly.

[0028] See also Figure 1-2 As shown, the pressing wheel group includes a pressing seat 321, two sets of wheel axles 412 and two sets of transmission wheels 413. The output end of the cylinder 311 is fixedly connected to the top of the pressing seat 321. The wheel axles 412 pass through the side walls at both ends of the pressing seat 321 and movably install the transmission wheels 413 in the cavity of the pressing seat 321.

[0029] Furthermore, at least one group of support legs 111 is provided at the bottom of the support arm 3 , and structures such as reinforcing ribs are added to the stress-bearing positions of the support arm 3 according to the supporting capacity of the material selected for the support arm 3 .

[0030] Furthermore, the strip groove 121 must not hinder the downward pressing of the transmission wheel 413.

[0031] In actual application, the conveyor belt transports the trolley to be installed with tires to the first mounting seat 1 and the second mounting seat 2. The staff pulls the trolley to the appropriate position. When the wheel frame at the bottom of the trolley passes through the rotating wheel 142, it is rotated by the rotating wheel 142. As a result, the wheel frame of the trolley is rotated to a state where the bolt holes face outward through the rotating wheel 142 and the side walls of the first mounting seat 1 and the second mounting seat 2 and is fixed to prevent it from turning. This allows the staff to install the tire without manual rotation or fixing when using it.

[0032] The cylinder 311 is activated, and its output drives the pressing seat 321, causing the transmission wheels 413 mounted on the pressing seat 321 to press against the trolley deck. The trolley deck is then pressed downward, causing the transmission wheels 413 within the multiple transmission wheel groups to move downward along the guide posts 416 until the bottom surface of the trolley contacts the rubber block 415. This secures the trolley deck position, preventing the trolley from changing position during tire installation and affecting the installation process. Simultaneously, the guide posts 132 and guide sleeves 131 are installed to adjust the lateral width of the device, making it adaptable to trolleys of various widths.

[0033] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to be limiting. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate that modifications or equivalent substitutions to the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be encompassed by the claims of the present invention.
