Description

Technical Field

[0001] This utility model relates to the field of tire disassembly technology, and in particular to a tooling for disassembling tire lock rings on engineering machinery. Background Technology

[0002] The main method for removing tire rim locks from heavy-duty wide-body mining dump trucks is as follows: First, deflate the tire, then insert a pry bar between the rim lock and the tire, secure it, and then use a sledgehammer to strike the secured pry bar. The purpose is to use the pry bar and the tire's support point as a lever point to separate the rim lock and the tire. If the dismantling worker is careless, the inserted pry bar may pop out and cause injury. If the tire has been used for a long time and the tire and rim have stuck together, it is necessary to first use a sledgehammer to strike until the rim lock separates from the tire lip. Then, the dismantling worker can use a pry bar and pry plate to remove the rim lock from the rim. The entire dismantling process cannot be accurately timed, especially for tires stuck to the rim. Multiple workers are needed to work on one tire simultaneously, making the entire process time-consuming, labor-intensive, and inefficient. The tire is easily damaged during operation, and careless operation can lead to safety accidents. Utility Model Content

[0003] This application provides a tooling for removing tire rim locks on engineering machinery, which improves the convenience and efficiency of rim lock removal.

The support includes a horizontal side and a vertical side. The horizontal side is used to cooperate with the side of the retaining ring for positioning, and the vertical side is used to insert into the inner side of the retaining ring and cooperate with the inner wall of the retaining ring for positioning.

[0005] The beneficial effects of the above embodiments are as follows: By pressing the retaining ring with the support rod and hooking the rim with the locking hook, the operator applies pressure to the main support rod on the other side and uses the lever principle to pry out the side of the rim, exposing the structure of the locking ring installed on the rim. The operator can then easily pry out the locking ring with a crowbar. Therefore, this disassembly tool has the characteristics of simple and convenient operation and labor saving, which can reduce the disassembly difficulty of the operator, improve the disassembly efficiency, and reduce the risk of crowbar rebound.

[0014] In the description of this application, it should be understood that the directional terms or positional relationships described are based on the orientation or positional relationships shown in the accompanying drawings, or based on the orientation or positional relationships in actual use, and are only for the purpose of facilitating the description of the contents of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0015] like Figure 1 As shown, a tooling for disassembling tire rim locks on engineering machinery includes: a main support rod 1, a locking hook 2, a support rod 3, and a support 4. The locking hook 2 is hinged to the main support rod 1 and is used to hook the rim. The support rod 3 is connected to the main support rod 1 and is arranged on the same side as the locking hook 2. The support 4 is connected to the end of the support rod 3. The support 4 includes a horizontal side and a vertical side. The horizontal side is used to cooperate with the side of the retaining ring for limiting, and the vertical side is used to insert into the inner side of the retaining ring and cooperate with the inner wall of the retaining ring for limiting.

[0016] In some embodiments of this application, such as Figure 1 As shown, the disassembly fixture also includes: side rods 5, two of which are symmetrically connected to both sides of the main support rod 1, and the locking hook 2 is hinged between the side rods 5. The side rods 5 clamp the locking hook 2 on both sides, which improves the strength of the connection structure and reduces the risk of deformation. Furthermore, the side rods 5 form a slot structure at the upper end of the main support rod 1, facilitating the rotation of the locking hook 2.

[0017] In some embodiments of this application, such as Figure 1 As shown, the main support rod 1 is a round tube with a length of 1000mm and a diameter of 20mm. The reason for choosing this type of round tube is that the diameter of the tire from the center of the rim to the outermost edge of the tire is approximately 800mm. A 1000mm long round tube is convenient for disassembly workers, and a 20mm diameter round tube is chosen to ensure that the tooling is not easily deformed or bent under stress. The side rod 5 consists of two round tubes with a length of 220mm and a diameter of 20mm, welded to one end of the main support rod 1. When assembling the 220mm round tubes, a distance is left between them and the main support rod 1 to facilitate the installation of the locking hook 2. During assembly, it is ensured that the center lines of the three round steel bars are in the same plane, and the welding method is double-sided welding.

[0018] In some embodiments of this application, such as Figure 1 As shown, the disassembly fixture also includes a pin 6, which is welded to the end of the side rod 5, and the locking hook 2 is rotatably connected to the pin 6. The locking hook 2 is rotatably connected via the pin 6, and the structure is simple and easy to manufacture.

[0019] In some embodiments of this application, such as Figure 1As shown, the locking hook 2 has an L-shaped structure. The L-shaped structure makes it easy to hook onto the inside of the wheel rim.

[0020] In some embodiments of this application, such as Figure 1 As shown, the side rod 5 forms a harpoon groove structure at the front end of the main support rod 1. The end of the locking hook 2 is inserted into the harpoon groove, and the pin 6 is passed through the through hole reserved at the end of the locking hook 2. Then, the pin 6 is fully welded flush with both sides of the harpoon groove.

[0021] In some embodiments of this application, such as Figure 1 As shown, the disassembly fixture also includes a reinforcing rod 7, one end of which is connected to the main support rod 1, and the other end of which is connected to the support rod 3. The reinforcing rod 7 forms a triangular structure between the main support rod 1 and the support rod 3, which reduces stress deformation of the intermediate support rod 3 itself and prevents deformation of the main support rod 1 and the L-shaped support 4 due to excessive leverage force during use, thereby increasing the strength and rigidity of the fixture body.

[0022] In some embodiments of this application, such as Figure 1 As shown, the support 4 further includes a connecting edge, which is arranged along the length of the support rod 3 and connected to the support rod 3. The connecting edge increases the connection length between the support 4 and the support rod 3, thereby improving structural strength and connection stability.

[0023] like Figure 2 As shown, when using this type of tire retainer removal tool for engineering machinery, the locking hook 2 is placed inside the tire rim, and the support 4 is supported on the side of the retainer ring with its vertical edge inserted inside. Utilizing the lever principle, the operator presses down on the main support rod 1, causing the locking hook 2 to lock the rim and lift it upwards. The rim and retainer ring change from a locked state to a state with a gap. At this point, a pry bar can be easily inserted into the gap between the rim and the retainer ring, and the rim can be gently pried off the rim. When using this tool for disassembly, care should be taken to ensure that the locking hook 2 does not coincide with the round hole on the side wall of the rim; otherwise, the round hole of the rim may be damaged when lifting the rim with force.

[0024] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, based on the guidance provided in this application, improve and implement this solution in combination with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
