[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically erecting a large tire.

[0002]

2. Description of the Related Art Large tires used for trucks and construction vehicles are often mounted via lock rings or side rings rather than directly mounted on wheels. After the tire is mounted on the wheel, the tire is filled with air, and the tire is mounted on a predetermined vehicle.
At this time, the tire assembling work and the air filling work are performed in a state where the tire is laid on the floor. When the tire is mounted on a vehicle, the tire must be raised and rolled to the vehicle.

However, the large tires weigh 100 kg or more, and require a large force to stand up a tire in a collapsed state. For example, 100
In the case of a tire having a weight of one kilogram, the force required to lift one end of the tire is approximately 50 kg, and when handling a large number of tires, it becomes extremely heavy labor. Therefore, if the tire is about 150 kg, ordinary people cannot stand it. In addition, the tires removed and transported from the vehicle are once fallen to the floor, and at this time, the tires may be rolled, which is very dangerous.

[0004]

As described above, a vehicle repair shop must handle tires of 100 kg or more, and it is not easy to cause a tire to fall down. The problem to be solved by the present invention is this problem, and provides a device for erecting a large tire or for safely and quietly falling down.

[0005]

The device for raising a large tire according to the present invention is a device for raising a tire in a collapsed state substantially vertically, and has the following features. That is, a base horizontally arranged facing the floor surface, an elevating member that is flexibly connected to the base, an elevating post that moves the elevating member up and down, and an auxiliary base at the base end, and further at the base end Rollers are supported. By the way, the elevating member moves up and down along the elevating post. However, the base moves with the elevating movement of the elevating member. The base moves up when it rises and falls down when it descends. The tip of the base moves on the floor surface supported by the rollers. Therefore, the tire mounted on the base is raised by the standing of the base. At this time, the auxiliary base connected to the front end of the base slides on the floor surface to serve as a cradle for an upright tire. Therefore, the lifting post is provided with a lifting device for raising and lowering the lifting member. On the other hand, the control device of the air filling machine may be attached to the device of the present invention. This is to eliminate the trouble of transporting the assembled tire to another place and filling the air. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0006]

1 and 2 show an embodiment of a tire erecting device according to the present invention. 1 is a base, 2 is a lifting member,
Reference numeral 3 denotes a lifting post, and 4 denotes an auxiliary base. The base 1 is connected to the elevating member 2 and bends with each other, and the auxiliary base 4 is connected to the base 1 so as to be bendable. Therefore, the joints 5 and 5 for bending are interposed between the elevating member 2 and the base 1 and between the base 1 and the auxiliary base 4.

The elevating member 2 has a horizontal portion 6 and an inclined portion 7 to form a substantially L-shape. The inclined portion 7 has four rollers 8,
, And these rollers 8, 8 contact the corners of the elevating post 3 so as to be able to move up and down along the elevating post 3. One horizontal portion 6 is in contact with the floor surface and is placed in a horizontal state together with the base 1 and the auxiliary base 4. The tire 9 is placed on the base 1 and the horizontal portion 6 in a state where the tire 9 has fallen. When the base 1 is erected, the tire 9 is raised.

The elevating post 3 is fixed to the floor and stands upright. An air cylinder 10 is provided inside the elevating post 3, and a sprocket 12 is mounted on a support 11 provided at the upper end of the piston rod of the air cylinder 10. A chain 13 is wound around the sprocket 12 and hangs on both sides. One end of the chain 13 is fixed to the elevating post 3, and the other end is fixed to the tip of the inclined portion 7 of the elevating member 2. If the piston rod of the air cylinder 10 protrudes, the sprocket 12 rises, and as a result, the lifting member 2 rises along the lifting post 3.

The elevating member 2 rises vertically, but at the same time, the base 1 is also pulled and stands up as shown by the two-point diagonal lines in FIG. However, the auxiliary base 4 slides on the floor surface in a horizontal state. Accordingly, the tire 9 placed on the base 1 while being tilted is raised when the base 1 stands up, and the tire 9 is mounted on the auxiliary base 4. Here, when the base 1 stands up, one end side is lifted by the elevating member 2 and the other end slides along the floor surface.
4 and 14 are rotatably attached.

The tire raising device shown in FIGS. 1 and 2 is merely one specific example. For example, the lifting device provided on the lifting post 3 is not limited to the air cylinder 10 but employs a rack-pinion mechanism. If the pinion is rotated by a motor, the rack can be moved up and down, and a screw mechanism can be employed. Furthermore, although the elevating member 2 has a substantially L-shaped horizontal portion 6, the horizontal portion is not always necessary, and the base 1 may be directly connected to the end of the inclined portion 7. Of course, if the horizontal portion 6 is not formed, the raising and lowering post 3 is raised by that amount and the raising and lowering member 2 is not raised so high that the tire 9 cannot be erected. Is preferred.

On the other hand, the auxiliary base 4 may be attached not only when it is flexibly connected to the tip of the base 1 but also by a structure which can be erected as shown in FIG. Normally, the auxiliary base 1 is set down when the tire is erected.
5 is also raised at the position shown by the dotted line. As described above, the present invention is an apparatus for erecting a tire, and the following effects can be obtained.

[0012]

[Effect of the Invention] The device of the present invention can erect the tire. Therefore, if the tire assembling operation and the air filling operation are performed on the base, even if the tire is very heavy, no labor is required. The tire can be rolled up in that state, carried to the place of the vehicle, and mounted on the vehicle. 100 kg
There is no problem even when working with large tires as described above, and this device can be used not only for erecting tires, but also for safely and quietly falling tires in the erect state.
