A movable ram 2 is installed vertically on both sides of the gate-shaped guide 4B.
A pair of through holes 11150 are formed in a direction perpendicular to 2A. In this penetration $150, support rods 52 protruding from both sides of the guide 48 in the width direction are attached substantially horizontally to the cylinder of the second driving means 22, and the penetration 115
It is arranged so as to be able to freely slide in the upward direction along the direction 0. One end of a link 54 is swingably attached to the end of the support rod 52 projecting from both end faces in the width direction of the guide 48 . The other end of the link 54 is pivotally connected to the tip of a lever 56 by a pin 58, the proximal end of which is pivotally supported on both end faces of the guide 48 in the width direction.
The distal end of the link 54, that is, the support rod 52 side, is biased upward by a spy 7 radial spring 60 attached to position B. Further, the end of the link 54 on the side of the support rod 52 or the support rod 52 is pulled against the spring force of the spiral spring 60, so that the movable ram 22A in the stomach, that is, the second driving means 22, is at the height of the support rod 52. A tension row 162 for adjusting the height position is connected. Reference numeral 64 in FIGS. 1 and 2 indicates support height adjustment means for the tire-equipped wheel 10. This support height adjustment means 64 is adapted to the wheel with tire 1.

The one-wheel mechanism 72 includes a driven bevel gear 72A attached to the lower end of the screw 6B, and a driven bevel gear 72A attached to the tip of a shaft 70A driven in conjunction with the handle 70.
A moving bevel gear 72B. Next, a process of disassembling and damaging the tire-equipped wheel 10 using the above embodiment apparatus will be explained. First, operate the handle 70 to adjust the height of the support height adjusting means 64 and the pipe member 66 in accordance with the outer diameter of the wheel with tire 10, and then adjust the height of the support height adjusting means 64 and the pipe member 66 to Roll the wheel 10 with ears vertically. At this time, the fixing claws 30 and 40 on the upper chucking means 24 and the lower chucking means 26 serve to prevent the tire-equipped wheel 10 from falling. In this state, the movable pawl 32 in the upper chucking means 24 is driven by the cylinder device 134, and the tire 12 is
Chuck both sides of the upper part in the width direction. At the same time, the movable claw 44 is driven by the cylinder device 42,
This and the fixed claw 40 chuck both sides of the lower part of the tire 12 in the width direction. The height of the support rod 52 is then adjusted to the height of the wheel 14 by means of the tension lobe 62. Next, the slider 2 is moved by the second driving means 22.
8 upwardly, thereby displacing the upper chucking means 24 upwardly, and thereby displacing the upper chucking means 24 upwardly.
4 and the lower chucking means 26 are separated. As a result, the tire 12 is pulled in the vertical direction, and at this time, the tire lead portion of the tire 12 is separated from the rim of the wheel 14 near the upper and lower ends of the wheel 14, and is partially damaged at the same time. At this time, although the tire 12 is separated from the wheel 14 at the upper and lower ends of the wheel 14, the bead wire of the tire 12 bites inward into the rim of the wheel 14 in the lateral diameter direction. , the wheel 14 is supported by the beat wire and does not fall off. Next, the movable ram 22A of the second drive means 22 is driven to move the rod 20 to the wheel 1 supported by the upper and lower chucking means 24, 26 via the tire 12.
4 to protrude substantially in the axial direction of the wheel 14 to press the wheel 14. When the rod 20 is strongly pressed against the wheel 14 in this state, the wheel 14 is deformed, and due to this deformation, the rim of the wheel 14 comes off from the peed wire of the tire 12, and the entire wheel 14 comes off from the tire 12. falls on the opposite side of the drive means 22. Therefore, in the above embodiment, when the tire 12 is first stretched by the upper and lower chucking means 24, 26, the tire 12 is damaged, and when the wheel 14 is pressed by the rod 20, this causes The wheel 14 is deformed and damaged, and at the same time the wheel 14 is removed from the tire 12, thereby completing the disassembly and damage work. In addition, in the process of disassembling and damaging the tire-equipped wheel 10 using the above embodiment device, the rod 20 is protruded by the second drive means 22 while the tire 12 is being pulled by the chucking means 16, and the wheel 14 is deformed and detached. In this case, the rod 20
When the chucking means 16 is slightly loosened before pressing the wheel 14 with the rod 20, the tire 12 of the wheel 14 after deformation is pressed.
It becomes easier to leave. Further, in the above embodiment, chucking means consisting of a fixed pawl and a movable pawl are provided on the top and bottom, but the present invention is not limited to this, and grips the tire 12 of the tire-equipped wheel 10 to move the chuck to the outside in the radial direction. Other configurations may be used as long as they can be pulled to a certain extent. Further, in the above embodiment, as the chucking means 16 for chucking the tire 12 of the tire-equipped wheel 10,
Although the upper and lower chucking means 24 and 26 grip the tire 12 at two places, the present invention is not limited thereto, and the chucking means chucks the tire and grips the tire 12 at two places. By pulling outward, a portion of the tire is detached from the wheel and damaged, and when the wheel 14 is subjected to an axial pressing force by the rod 20 in the next step, the tire 12 is removed before it is deformed.
Any material may be used as long as it can hold the wheel with tire 10 so that it does not come off. Therefore, the chucking means may be one that grips the tire 12 at three or four locations and pulls it outward. Also, a first driving means for driving the chucking means 16 and a second driving means 2 for driving the rod 20.
2 are each constituted by a hydraulic cylinder device, but the present invention is not limited to this, and these drive means may be other mounting means, such as a screw, a link mechanism, etc.

[Effects of the Invention] ' Since the present invention is configured as described above, the wheel can be deformed from the tire with a small force, compared to the case where force is applied in the diametrical direction, which has high strength and requires a large amount of energy for deformation. and can be separated, and
It has an excellent effect in that the tire can be damaged to the point where it cannot be reused when it is damaged. Furthermore, as described in Japanese Patent Application Laid-Open No. 56-75206, the inner wheel can be removed by placing a tire with a wheel on a female bracket and pushing it diametrically with a male bracket. There are some that are deformed and reduced in size so that they can separate from the tire. However, the wheel extraction device described in this publication is very large in size, and since the wheel-equipped tire is pushed from only one side using a male metal fitting, the wheel on the opposite side of the wheel is pushed into the tire. In addition to this problem, even if the male metal fitting presses the wheel with the tire in its radial direction, causing the inner wheel to deform and contract, the outer tire will return to its original shape due to its elasticity. This poses a problem in that after the wheel is removed, the tire must be rendered unusable by other means. The present invention can solve all of the above problems.
