Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire repair, specifically a pneumatic tire rim disassembly machine. Background Technology
[0002] Inflating, repairing, and replacing truck tires all require removing the tire assembly from the rim. Currently, truck tire assembly removal involves manually loosening the inner and outer tires and rim by striking with a heavy hammer. Due to the heavy loads of trucks or the susceptibility of water to entering the rims, the steel rim joint of the inner and outer tire assemblies is prone to rust, increasing the difficulty of removal.
[0003] When disassembling a heavy-duty truck tire assembly, the position of the vibratory hammer needs to be constantly changed. This process can easily lead to injuries to maintenance personnel, and if the hammer's swing force is insufficient, the tire assembly may become difficult to loosen and remove. Therefore, there is an urgent need for a pneumatic tire rim removal machine to avoid workplace accidents and to provide a stable solution for removing tire rims. Utility Model Content
[0004] The purpose of this invention is to provide a pneumatic tire rim disassembly machine to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, a pneumatic tire rim disassembly machine is provided, including a disassembly platform. A pressure frame structure and a disassembly table mechanism are installed on the disassembly platform, and a tire is placed on it. A steel rim is provided on the inner side of the tire. A vertical frame is fixedly installed at the end of the disassembly platform, and a gantry frame is fixedly installed on the top of the vertical frame. A cylinder is fixedly installed on the gantry frame, and the output shaft of the cylinder is located directly above the tire.
[0006] Furthermore, the disassembly machine platform is provided with a tire positioning groove and a disassembly table positioning groove, and a pressure frame positioning groove is provided at the bottom of the tire positioning groove.
[0007] Furthermore, the tire positioning groove is adapted to the size of the tire, and the bottom of the tire is positioned inside the tire positioning groove, with a pressure frame structure placed on the tire.
[0008] Furthermore, the pressure frame structure includes a pressure platform, columns, and a pressure plate, and both the pressure platform and the pressure plate are circular with the same diameter. The size of the pressure platform is adapted to the positioning groove of the pressure frame. Multiple sets of columns are equidistantly arranged between the pressure platform and the pressure plate. A disassembly platform mechanism is provided on one side of the pressure frame structure.
[0009] Furthermore, the disassembly platform mechanism includes a force-bearing platform, support columns, and an impact plate, with multiple sets of support columns equidistantly arranged between the force-bearing platform and the impact plate.
[0010] Furthermore, the impact disc is adapted to the size of the positioning groove of the disassembly table, and the impact disc is engaged inside the positioning groove of the disassembly table.
[0011] Furthermore, both the force-bearing platform and the pressure platform are provided with insertion holes, and the insertion holes are adapted to the size of the cylinder's output shaft, while the cylinder's output shaft is inserted into the insertion holes.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This solution involves placing the tire on the pressure plate surface of the pressure frame structure, with the steel rim inside the tire suspended in the air. The impact plate of the disassembly platform is then placed on the steel rim, and the output shaft of the cylinder impacts the pressure plate. The steel rim surface is then subjected to force and moves downwards, while the tire remains stationary due to the support of the pressure frame structure. The process continues until the steel rim falls into the interior of the pressure frame structure, completing the disassembly of the tire's internal steel rim. The entire process eliminates the need for manual, continuous hammering of the tire, reducing the risk of workplace injuries. The disassembly method is also simple and quick. 2. This solution allows the steel ring to detach from other components by suspending it in mid-air. Only a downward force from the cylinder impact is needed to push the steel ring directly down, without having to overcome the adhesive resistance between the steel ring and other components. The steel ring eventually falls into the pressure frame structure, which not only completes the separation but also supports the steel ring, preventing it from falling directly to the ground and causing damage. It also facilitates the subsequent removal of the steel ring and reduces additional handling steps. Attached Figure Description

[0015] Please see Figure 1-5This utility model provides a pneumatic tire rim disassembly machine, including a disassembly machine platform 1, on which a pressure frame structure 3 and a disassembly table mechanism 4 are installed, and a tire 5 is placed on it. A steel rim 51 is provided on the inner side of the tire 5. A stand 14 is fixedly installed at the end of the disassembly machine platform 1, and a gantry frame 15 is fixedly installed on the top of the stand 14. A cylinder 2 is fixedly installed on the gantry frame 15, and the output shaft of the cylinder 2 is located directly above the tire 5.
[0016] Working principle: When this device is used in actual use, first place the tire 5 in the tire positioning groove 11 on the dismantling machine 1 to quickly position the tire 5. At this time, place the pressure frame structure 3 on the tire 5. The pressure plate 33 at the bottom of the pressure frame structure 3 covers the outer surface of the tire 5. Then, start the external switch of the cylinder 2. The output shaft of the cylinder 2 drives the pressure frame structure 3 to move downward. The pressure plate 33 at the bottom of the pressure frame structure 3 presses down on the tire 5, exposing the outer side of the clamp on the inner surface of the tire 5. The clamp can be removed using a pry bar. At this time, the output shaft of the cylinder 2 moves upward, removing the pressure frame structure 3 and the tire 5 from the dismantling machine 1. First, the pressure plate 31 on the pressure frame structure 3 is engaged with the pressure frame positioning groove 12 opened on the disassembly machine platform 1, and the pressure frame structure 3 is inverted. Then, the tire 5 is placed on the surface of the pressure plate 33 on the pressure frame structure 3. At this time, the steel rim 51 inside the tire 5 is in a suspended state. Then, the impact plate 43 on the disassembly platform mechanism 4 is placed on the steel rim 51, and the output shaft of the cylinder 2 impacts the force-bearing platform 41. At this time, the surface of the steel rim 51 is subjected to force and moves downward. The tire 5 is supported by the pressure frame structure 3 and remains stationary until the steel rim 51 falls into the interior of the pressure frame structure 3, completing the disassembly of the steel rim 51 inside the tire 5. The whole process does not require manual constant changing of the vibrating hammer to strike the tire, which is less likely to cause work-related accidents. The disassembly method is also simple and fast. In a preferred embodiment, the disassembly machine 1 is provided with a tire positioning groove 11 and a disassembly table positioning groove 13, and a pressure frame positioning groove 12 is provided at the bottom of the tire positioning groove 11.
[0017] The tire positioning groove 11 is adapted to the size of the tire 5, and the bottom of the tire 5 is positioned inside the tire positioning groove 11, with a pressure frame structure 3 placed on the tire 5.
[0018] In a preferred embodiment, the pressure frame structure 3 includes a pressure platform 31, columns 32, and a pressure plate 33. Both the pressure platform 31 and the pressure plate 33 are circular, and their diameters are the same. The size of the pressure platform 31 is adapted to the size of the pressure frame positioning groove 12. Multiple sets of columns 32 are equidistantly arranged between the pressure platform 31 and the pressure plate 33. A disassembly platform mechanism 4 is provided on one side of the pressure frame structure 3.
[0019] The disassembly platform mechanism 4 includes a force-bearing platform 41, support columns 42 and impact plate 43, with multiple sets of support columns 42 equidistantly arranged between the force-bearing platform 41 and the impact plate 43.
[0020] The impact plate 43 is matched with the size of the disassembly table positioning groove 13, and the impact plate 43 is snapped into the inside of the disassembly table positioning groove 13.
[0021] Both the force-bearing platform 41 and the pressure platform 31 are provided with insertion holes, and the insertion holes are adapted to the size of the output shaft of the cylinder 2. At the same time, the output shaft of the cylinder 2 is inserted into the inside of the insertion hole.
[0022] like Figure 1-5 As shown: Tire 5 is placed in tire positioning groove 11 of disassembly machine 1; the pressure plate 31 of pressure frame structure 3 engages with pressure frame positioning groove 12 of disassembly machine 1, solving the problem of component displacement and difficult alignment during disassembly: Tire positioning groove 11 can quickly limit the placement position of tire 5, preventing tire 5 from shifting when pressure frame structure 3 is pressed down, ensuring that pressure plate 33 accurately covers the outer surface of tire 5, providing a stable premise for the outer side of clamp to be exposed; Pressure frame positioning groove 12 fixes the position of pressure frame structure 3 when it is inverted, preventing pressure frame structure 3 from tipping over, ensuring that when tire 5 is placed on the surface of pressure plate 33, steel rim 51 can be stably suspended, avoiding uneven force on steel rim 51 due to displacement of pressure frame 3; The entire process uses cylinder 2 as the core power source, replacing the manual pressing and brute force prying in traditional manual disassembly, significantly improving operational efficiency and reducing physical exertion: During the clamp removal stage, there is no need to manually press the tire 5. Simply by activating the external switch of cylinder 2, the pressure plate 33 of the pressure frame structure 3 can be driven to stably press down the tire 5, quickly exposing the outer side of the clamp on the inner side of the tire 5 surface, eliminating the tedious steps of manually fixing the tire 5; During the rim separation stage, there is no need to manually knock or pull the rim 51. With the impact of the output shaft of cylinder 2 on the force platform 41, the impact force can be directly transmitted to the impact plate 43, thereby pushing the rim 51 downward. Compared with manual separation, it is more labor-saving and can quickly complete the separation of the rim 51 from the tire 5, greatly shortening the disassembly time; When the pressure plate 33 presses down on the outer surface of the tire 5, it can evenly distribute the pressure of the cylinder 2 to the surface of the tire 5, avoiding excessive local pressure that could cause tire tread deformation. At the same time, it makes the process of exposing the outer side of the clamp more gentle, without having to pry the inner side of the tire 5 hard, thus protecting the integrity of the inner edge of the tire 5. When separating the steel rim 51, the impact plate 43 is placed on the steel rim 51 first, which can buffer the direct force of the impact of the cylinder 2, preventing the surface of the steel rim 51 from denting or cracking due to excessive instantaneous force. Moreover, the tire 5 is stably supported and kept stationary by the pressure frame structure 3, and the steel rim 51 only moves along a single trajectory as it falls into the pressure frame structure 3, without rubbing or colliding with the inner side of the tire 5, thus protecting the contact surfaces of the two from damage. The suspended state allows the steel ring 51 to detach from contact with other components. Only the impact of the cylinder 2 is needed to provide a downward force to push the steel ring 51 directly down, without having to overcome the adhesive resistance between the steel ring 51 and other components. The steel ring 51 eventually falls into the inside of the pressure frame structure 3, which not only completes the separation but also supports the steel ring 51 through the pressure frame structure 3, preventing the steel ring 51 from falling directly to the ground and causing damage. At the same time, it facilitates the subsequent removal of the steel ring 51 and reduces additional handling steps.
