に載置されタイヤの脱着操作は完了する。 Next, after removing the side ring 21 from the wheel 18 in a conventional manner, the second side ring 21 is removed from the wheel 18 as shown in FIG.
The pressurizing cylinder 3 is operated to lower the piston rod 16, the horizontal bar 4 and the receiving fitting 9 are removed from the piston rod 7, and the wheel plate 22 is placed on the bulge 18b of the wheel 18. In addition, the wheel plate 22
has a diameter that allows it to be placed on the wheel bulge 18b, and is configured in the shape of a disk with a hole in the center through which the piston rod 7 is inserted. Next, after setting the receiving fitting 9 on the piston rod 7, when the pressurizing cylinder 2 is operated to lower the piston rod 7, the wheel 18, from which the inner edge 6a of the tire 6 has already been removed, is pushed down by the wheel plate 22. While the tire 6 is held on the upper edge of the frame 1, it is detached from the inner edge 6b of the tire 6 and placed on the mounting table 5 which is descending as shown in FIG. 2, completing the tire attachment and detachment operation.

的効果を有するものである。 As described above, the present invention houses a first pressurizing cylinder and a second pressurizing cylinder in a frame whose upper edge is a tire support part, and both ends are attached to the upper end of a piston rod that is raised and lowered by the first pressurizing cylinder. This is a tire attachment/detachment device that is constructed by detachably inserting a horizontal bar with a tire detachment piece hanging down from the top and a wheel mounting stand fixed to the upper end of a piston rod that is raised and lowered by a second pressurizing cylinder. Therefore, all the device parts are housed within the cylindrical frame, and the frame itself also serves as a support for the tires, simplifying the structure of the device, making transportation and maintenance easy, and manufacturing costs low. In addition, there is no need to assemble or disassemble many parts during use, and there is no need to turn the tire over midway, so the installation and removal operations are greatly simplified. Furthermore, since most of the attachment/detachment operations are performed by operating the pressurized cylinder, it has excellent practical effects, such as greatly reducing labor.
