[0022] A solid tire disassembly and assembly tool comprises a frame 1, wherein an upper support frame 12 and a lower support frame 2 are respectively arranged at the upper and lower parts of the frame 1, wherein: a tire pressure cylinder 11 and a tire removal pressure cylinder 14 are arranged at intervals on the upper support frame 12, a tire pressure sleeve 9 is arranged at the lower end of the piston rod of the tire pressure cylinder 11 (the two are connected by threads or by positioning bolts, when the positioning bolts are used for connection, the positioning bolts penetrate the body wall of the tire pressure sleeve 9 and the top end is in constant pressure contact or connection with the piston rod), and a tire pressure hub plate 7 and a tire positioning plate 8 are respectively arranged on the tire pressure sleeve 9 (the tire pressure hub plate 7 is circular and can press the wheel hub, and the tire positioning plate 8 can be circular, can be straight-lined, or can be cross-star shaped, Determined according to needs, not listed one by one), a tire guiding hole (not shown in the figure) is provided on the tire positioning plate 8, and a tire guiding rod 10 is provided in the tire guiding hole, and the two are slidably matched, and a tire pressure plate 5 is provided at the lower end of the tire guiding rod 10, and a spring 6 is sleeved on the tire guiding rod 10 between the tire pressure plate 5 and the tire positioning plate 8, and the upper end of the tire guiding rod 10 is slidably connected with the through hole on the upper support frame 12 (not shown in the figure); a tire removing pressure sleeve 15 is provided at the lower end of the piston rod of the tire removal pressure cylinder 14, and the tire removing pressure sleeve 15 is provided with a tire removal barrel 16, and a lifting pressure cylinder 17 is provided on the lower support frame 2, and a lifting pressure plate (not shown in the figure) is provided at the upper end of the piston rod of the lifting pressure cylinder 17.

[0023] Preferred solution: The upper and lower ends of the tire removal barrel 16 are respectively provided with flange edges, and tire removal guide holes 18 are respectively provided on the two flange edges. A tire removal guide rod 13 is provided in the tire removal guide hole 18, and the two are slidably matched. The upper end of the tire removal guide rod 3 is slidably connected to another through hole on the upper support frame 12, and the lower end flange edge of the tire removal barrel 16 serves as a tire removal pressure ring 19.

[0024] Preferred solution: the upper and lower ends of the spring 6 are respectively connected to the tire positioning plate 8 and the tire pressure plate 5 to prevent the tire guide rod 10 from falling off. In addition, a detachable block or nut is provided on the upper end of the tire guide rod 10 to prevent the tire guide rod 10 from detaching from the upper support frame 12.

[0025] Preferred solution: The tire mounting pressure cylinder 11, the tire removal pressure cylinder 14 and the lifting pressure cylinder 17 are all pneumatic cylinders or hydraulic cylinders. A travel switch (not shown) is provided on the frame 1 to determine the limit position of the movement of the piston rods of the tire mounting pressure cylinder 11, the tire removal pressure cylinder 14 and the lifting pressure cylinder 17.

[0026] When installing the tire, the solid tire 3 is placed just below the tire installation pressure cylinder 11, and the wheel hub 4 is placed at the center hole of the solid tire 3. The tire installation pressure cylinder 11 is started, so that its piston rod drives the tire installation pressure sleeve 9 to move downward, and the tire installation pressure plate 5 first contacts the upper end surface of the solid tire 3, and the piston rod continues to move downward. Relying on the pressure of the spring 6, the tire installation pressure plate 5 presses the solid tire 3 to position it, and then the tire installation hub plate 7 contacts the wheel hub 4 and presses it into the center hole of the solid tire 3 and installs it in place. The tire installation pressure cylinder 11 moves in the opposite direction, and its piston rod takes the tire installation pressure sleeve 9 out of the solid tire 3, completing a tire installation process.

[0027] When removing the tire, the solid tire 3 with the wheel hub 4 is placed just below the tire removal pressure cylinder 14, and the tire removal pressure cylinder 14 is started, so that its piston rod drives the tire removal pressure sleeve 15 to move downward, and the tire removal pressure ring 19 presses the solid tire 3 to position it, and then the lifting pressure cylinder is started, and its piston rod drives the pressure plate to separate the wheel hub 4 from the solid tire 3. Finally, the tire removal pressure cylinder 14 and the lifting pressure cylinder 17 move in opposite directions, and the piston rod of the tire removal pressure cylinder 14 drives the tire removal pressure sleeve 15 to separate from the solid tire 3, and the piston rod of the lifting pressure cylinder 17 returns to its position, completing a tire removal process.

[0028] When the tire removing pressure ring 19 presses the solid tire 3, the lower end of the tire removing guide rod 13 does not contact the solid tire 3, thereby avoiding the phenomenon that the tire removing pressure ring 19 cannot press the solid tire 3 due to the excessive length of the tire removing guide rod 13.

[0029] Embodiment 2: This embodiment is basically the same as Embodiment 1, and the similarities are not repeated. The difference is that the tire pressure plate is a circular ring segment structure, or an overall circular ring structure, or a square structure, depending on the actual situation.

[0030] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any simple modification made according to the technical essence of the utility model still falls within the scope of the technical solution of the utility model.
