Description

Technical Field

[0001] The utility model belongs to the technical field of tire installation, and in particular relates to a special tire tool for tire installation. Background Art

[0002] Tires are often replaced or installed during port operations. The port's operating equipment is relatively large, and the size and weight of the tires are also large and heavy. When installing the tire, there is a sealing ring between the tire seat and the steel rim, which plays the role of enclosing air to ensure tire pressure. The sealing ring can only be installed after the tire is inserted into the steel rim. However, due to the high hardness of the tire, 2 to 3 people are required to use a long crowbar to use the steel rim as a fulcrum to press down the tire seat, so that the tire seat deforms downward, and then the sealing ring is embedded in the gap caused by the deformation of the tire seat. Sometimes another forklift is required to cooperate with the downward pressure. If the balance is not grasped, the sealing ring will be scrapped. This process is not only time-consuming and labor-intensive, but also the sealing ring is easily scrapped due to the lack of balance, which increases material consumption, mainly the consumption of the sealing ring. The price of the sealing ring ranges from 300 to 800 yuan, which is a large loss and also poses a large safety risk.

[0003] The main difficulty in installing tire seals is that it is difficult to control the force when using a crowbar or forklift, the tire seat deforms to different degrees in all directions, the overall balance is poor, and it is easy to shake. Summary of the invention

[0004] The utility model aims to design a special tire jig for installing a tire. The tire jig has a simple structure and is easy to use. When in use, the installation can be achieved by simply rotating a screw handle rod.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A special jig for installing tires comprises a base, a screw rod is vertically arranged in the middle of the base, a horizontal rod and a rotating extrusion rod are sequentially installed on the screw rod from bottom to top, a tire to be installed is placed between the horizontal rod and the base, the rotating extrusion rod comprises a middle nut, the nut extends out of the extrusion rod, and the end of the extrusion rod is a handle.

[0007] Furthermore, the number of the rotating extrusion rods is 3, and the 3 extrusion rods are evenly installed around the nut.

[0008] Furthermore, the horizontal rod is in a straight line shape, with a through hole in the middle, and a pair of extrusion blocks are provided on the lower surface of the horizontal rod.

[0009] Furthermore, the inner wall of the through hole is provided with threads or is a smooth surface.

[0010] Furthermore, the base is in a cross shape.

[0011] Furthermore, the base, the screw rod, the horizontal rod and the rotating extrusion rod are all made of metal materials.

[0012] The following beneficial effects can be obtained through the above technical solution:

[0013] The special tire tool is easy to use and can steadily press the tire seat down to a suitable height. One person can operate the entire device. The utility model is suitable for the installation of tire sealing rings of any large machinery. The overall balance is good during installation and there is no shaking. Secondly, the consumption of tire sealing rings is reduced to a minimum, saving maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] like Figure 1-4 As shown, a special jig for installing tires includes a base 1, which is cross-shaped and has a fixed bolt hole at the end for easy fixing on the ground. A screw rod 4 is vertically welded in the middle of the base 1. The screw rod 4 is sequentially installed with a horizontal rod 2 and a rotating extrusion rod 3 from bottom to top. The tire to be installed is horizontally placed between the horizontal rod 2 and the base 1. The rotating extrusion rod 3 includes an intermediate nut 5, and the nut 5 extends an extrusion rod. There are three extrusion rods, which are evenly installed around the nut 5. The end of the extrusion rod is a handle 6. The horizontal rod 2 is in a straight line shape, with a through hole 8 in the middle. A pair of extrusion blocks 7 are provided on the lower surface of the horizontal rod, and the pair of extrusion blocks 7 can just squeeze the side of the wheel hub.

[0022] During specific use, after the base is effectively fixed, the tire to be installed is inserted into the screw and placed horizontally. The horizontal rod 2 is first inserted, and then the rotating extrusion rod 3 is screwed in. At this time, a pair of extrusion blocks 7 just rest against the side of the wheel hub. The operator rotates the rotating extrusion rod 3 to squeeze the horizontal rod 2 downward, thereby pressing the wheel hub into the tire. The installation success rate is high and the tire sealing ring loss is low.

[0023] The production of this tire jig is not only suitable for the installation of any large-scale mechanical tire seal ring, but also reduces the original operation process of 3 people and 4-5 hours per tire to the current one person and 1 hour per tire, and no mechanical coordination is required. It has been verified that it not only saves human and machine resources and material costs of at least 8,000 yuan per year, but also reduces energy consumption by 60%, and greatly improves the safety factor of operation.

[0024] The above are all preferred implementations of the present invention. For ordinary technicians in this technical field, without departing from the principle of the present invention, various equivalent modifications to the present invention belong to the protection scope of the claims attached to this application.
