Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for automatically raising a large tire.

[0002]

[Prior art]

 Large tires used in trucks and construction vehicles are often mounted via lock rings or side rings rather than being mounted directly on the wheels. After mounting the tire on the wheel, the tire is filled with air and the tire is attached to a predetermined vehicle. At this time, the tire assembling work and the air filling work are performed with the tire lying down on the floor surface, and when the tire is attached to a vehicle, the tire must be raised and rolled to the vehicle.

However, the above-mentioned large tire has a weight of 100 kg or more, and a large force is required to stand up the tire in a fallen state. For example, a 100 kg tire requires about 50 kg of force to lift one end of the tire, which is a heavy labor when handling a large number of tires. Therefore, with a tire of about 150 kg, an ordinary person cannot stand up. In addition, the tire removed from the vehicle and carried will be laid on the floor once, but at this time the tire may roll, which is extremely dangerous.

[0004]

[Problems to be solved by the present invention]

 As described above, a vehicle repair shop must handle tires weighing 100 kg or more, and it is not easy to raise a fallen tire. The problem to be solved by the present invention is this problem, and it provides a device for erecting a large tire and for safely and silently inclining it.

[0005]

[Means for Solving the Problems]

 The large tire standing device according to the present invention is a device for standing a tire in a fallen state almost vertically, and has the following features. That is, there is a base horizontally arranged facing the floor, a lifting member that is bendably connected to the base, a lifting post that moves the lifting member up and down, an auxiliary base at the tip of the base, and a base tip. Is supporting the roller. By the way, the elevating member moves up and down along the elevating post, and the base moves as the elevating member moves up and down, and when it rises, it stands up and when it descends, it falls. The tip of the base is supported by rollers and moves on the floor. Therefore, the tire mounted on the base is raised by the standing of the base. At this time, the auxiliary base that is connected to the tip of the base slides on the floor and serves as a stand for the standing tire. Therefore, the lifting post is equipped with a lifting device for moving the lifting member up and down. 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 carrying the assembled tire to another place and filling the air. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

【Example】

 1 and 2 show an embodiment of a tire standing device according to the present invention. In the figure, 1 is a base, 2 is a lifting member, 3 is a lifting post, and 4 is an auxiliary base. The base 1 is connected to the elevating member 2 and bends to each other, and the auxiliary base 4 is connected to the base 1 in a bendable manner. Therefore, bending joints 5 and 5 are interposed between the lifting 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, and the inclined portion 7 axially supports four rollers 8, 8 ... And these rollers 8, 8 ,. Is in contact with a corner of the elevating post 3 and can be moved up and down along the elevating post 3. One horizontal portion 6 is in contact with the floor and is placed in a horizontal state together with the base 1 and the auxiliary base 4. Then, the tire 9 is placed on the base 1 and the horizontal portion 6 in a state where the tire 9 is tilted, but the tire 9 is raised by erecting the base 1.

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 tool 11 provided at the upper end of the piston rod of the air cylinder 10. The sprocket 12 is supported, and a chain 13 is wound around the sprocket 12 and hangs down 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. Then, if the piston rod of the air cylinder 10 projects, 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-dot diagonal line in FIG. However, the auxiliary base 4 slides on the floor in a horizontal state. Therefore, the tire 9 placed on the base 1 in a tilted state is raised with the standing of the base 1, and the tire 9 is placed 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. The rollers 14 and 14 are rotated so that the other end can slide. It is attached freely.

The tire standing device shown in FIGS. 1 and 2 is merely one specific example. For example, the lifting device provided to the lifting / lowering post 3 is not limited to the air cylinder 10, but a rack-pinion mechanism is used. Then, if the pinion is rotated by a motor, the rack can move up and down, and a screw mechanism can be adopted. Further, although the elevating member 2 is roughly L-shaped and has the 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 tire 9 cannot be erected unless the elevating post 3 is raised accordingly and the elevating member 2 is raised higher. Is preferred.

On the other hand, the auxiliary base 4 is not limited to the case of being flexibly connected to the tip of the base 1, but may be attached with a structure that can stand upright as shown in FIG. When the tire is to be erected, the auxiliary base 15 is also erected at a position indicated by a dotted line when the tire is normally erected. As described above, the present invention is a device for raising a tire, and can obtain the following effects.

[0012]

[Effect of device]

 Since the device of the present invention can raise the tire, therefore, if the tire assembling work and the air filling work are performed on the base, even a very heavy tire can be used without any effort. It is possible to stand up, and the standing tire can be rolled in that state and carried to the vehicle and mounted on the vehicle. There is no problem even when working with large tires weighing 100 kg or more, and this device can be used not only for standing up the tire but also for safely and quietly tilting the standing tire.
