Description

Technical Field

[0001] This utility model relates to the field of tire installation technology. More specifically, this utility model relates to a rim lock ring installation device. Background Technology

[0002] The load-bearing requirements of off-highway mining dump trucks are constantly increasing with the improvement of mining efficiency. Their operating roads are often winding and potholed, with worse road conditions than those of highway dump trucks, significantly increasing the load on the vehicle wheels. To meet the high load-bearing requirements, these vehicles often use a combination structure of rims, locking rings, and retaining rings. The tires and bead surfaces are relatively hard, resulting in a high tire load coefficient, faster wear, and frequent replacements. Currently, the traditional method of locking ring installation involves fitting the tire to the rim body horizontally on the ground, with the operator placing the retaining ring and locking ring, and pressing them in using foot pedals, pry bars, or hammering. This installation method has significant drawbacks: First, locking ring installation is difficult, usually requiring two or three workers to install, which is time-consuming and labor-intensive. Second, manual operation relies on tools such as pry bars, which can easily damage the appearance of the workpiece. Furthermore, due to the variety of locking ring diameters, the traditional method cannot quickly adapt to different sizes, requiring frequent adjustments to tool positions during installation, further reducing installation efficiency. This is the technical problem that this application urgently needs to solve. Utility Model Content

The upper end of the hoisting structure is fixedly connected to the upper base (1), and the lower end of the hoisting structure is connected to the tire rim assembly (12).

[0008] When the piston rod of the hydraulic jack (4) extends vertically upward, the lower base (5) transmits pressure to the pressure block (11) through the pressure rod (7) and the guide rail (8), so that the bottom of the pressure block (11) is in close contact with the end face of the lock ring (13), driving the lock ring (13) to move downward. At the same time, the upper base (1) drives the tire rim assembly (12) to move upward through the hoisting structure, and the lock ring (13) is installed through the relative movement of the tire rim assembly (12) and the lock ring (13).

[0028] like Figure 1-3 As shown, this utility model provides a rim lock ring installation device, comprising:

[0029] The power assembly includes a hydraulic jack (4) and a lower base (5). The lower base (5) is a circular or rectangular steel plate structure with bolt holes in the center of the top surface. The cylinder of the hydraulic jack (4) is fixed above the lower base (5) and can be connected by high-strength bolts. The piston rod of the hydraulic jack (4) extends vertically upward. When the piston rod of the hydraulic jack (4) is lifted upward, the upper base (1) is subjected to axial thrust, and the lower base (5) is subjected to reaction force, which is transmitted to the positioning assembly through the pressure rod (7).

[0030] The positioning assembly includes a pressure rod (7), a guide rail (8), a locking pin (10), and a pressure block (11). Multiple pressure rods (7) are evenly connected circumferentially to the lower base (5). The lower end of each pressure rod (7) is fixedly connected to the guide rail (8). The guide rail (8) is slidably connected to the pressure block (11). The locking pin (10) is sequentially inserted into the pin holes of the guide rail (8) and the pressure block (11) to fix the position of the pressure block (11). Specifically, after releasing the locking pin (10), the pressure block (11) is pushed to slide along the T-groove of the guide rail (8). The position is determined by a ruler (accuracy 1). After positioning (mm), tighten the locking pin (10) after adjustment. Fix it by inserting the bottom end of the pin into the pin hole of the pressure block (11). When the piston rod of the hydraulic top (4) is lifted, the lower base (5) presses the pressure rod (7) downward. The pressure is transmitted to the pressure block (11) through the pressure rod (7) and the guide rail (8). The pressure block (11) acts on the end face of the lock ring (13), so that the bottom of the pressure block (11) is close to the end face of the lock ring (13), driving the lock ring (13) to move downward.

[0031] The lifting assembly includes an upper base (1) and a hoisting structure. The upper base (1) is a circular or rectangular I-beam steel plate structure. The upper base (1) is fixed to the top of the piston rod of the hydraulic jack (4). The hoisting structure is not limited to a hinged quick-release structure, a snap-on quick-release structure, a gear and rack adjustment structure, etc. The upper end of the hoisting structure is fixedly connected to the upper base (1), and the lower end of the hoisting structure is connected to the tire rim assembly (12). When the piston rod of the hydraulic jack (4) is lifted, the upper base (1) drives the tire rim assembly (12) to move upward through the hoisting structure. The relative movement between the tire rim assembly (12) and the locking ring (13) realizes the pressing of the locking ring (13).

[0032] When the piston rod of the hydraulic jack (4) extends vertically upward, the lower base (5) transmits pressure to the pressure block (11) through the pressure rod (7) and the guide rail (8), so that the bottom of the pressure block (11) is in close contact with the end face of the lock ring (13), driving the lock ring (13) to move downward. At the same time, the upper base (1) drives the tire rim assembly (12) to move upward through the hoisting structure, and the lock ring (13) is installed through the relative movement of the tire rim assembly (12) and the lock ring (13).

[0033] During operation, first adjust the position of the pressure block (11) in the guide rail (8) according to the diameter of the locking ring (13), and then fix it with the locking pin (10). Then place the lower base (5) on the upper surface of the locking ring (13). Start the hydraulic jack (4), the piston rod lifts and drives the upper base (1) to move upward, and pulls the tire rim assembly (12) through the hoisting structure, so that the tire rim assembly (12) is lifted upward; at the same time, the lower base (5) transmits pressure to the pressure block (11) through the pressure rod (7) and the guide rail (8), driving the lock ring (13) to move downward. The force transmission path is as follows: the hydraulic jack pushes the upper base (1) to the hoisting structure to the rim assembly (12) to achieve upward lifting, and the hydraulic jack reaction force goes to the lower base (5) to the pressure rod (7) to the guide rail (8) to the pressure block (11) to the lock ring (13) to achieve downward pushing. Through the relative movement of the two, the lock ring (13) is pressed into the mounting groove of the tire rim assembly (12).

[0034] In the above technical solution, the hydraulic jack (4) provides power to replace manual operation. The mechanical positioning and lifting structure realizes the relative motion pressing of the lock ring (13) and the tire rim assembly (12). No manual hammering is required. The installation can be completed by a single person, which significantly improves efficiency and reduces workpiece damage. It is suitable for the characteristics of large load and harsh road conditions of off-highway mining dump trucks. The pressing is stable and ensures that the lock ring can work reliably for a long time under complex working conditions.

[0035] In another technical solution, four pressure rods (7) are uniformly welded around the circumference of the lower base (5). The four pressure rods (7) are distributed at 90° intervals to form a symmetrical support structure. This layout allows the pressure borne by the lower base (5) to be evenly distributed to the four pressure rods (7), avoiding local overload and enhancing the structural rigidity. Preferably, a guide rail (8) is welded to the lower end of each pressure rod (7). The length direction of the guide rail (8) points to the center of the circle to ensure the radial positioning accuracy when the pressure block (11) slides. This allows the pressure to be evenly transmitted to the guide rail (8) and the pressure block (11) through the pressure rod (7), ensuring the force balance of the locking ring (13). This is especially suitable for the pressing of large-diameter locking rings (13) to ensure the stability and reliability of the equipment under high pressure.

[0036] In another technical solution, a T-shaped groove is provided inside the guide rail (8), and a pin hole is provided on the top surface of the T-shaped groove. The depth of the pin hole is designed to allow the locking pin (10) to pass through. The locking pin (10) passes through the pin hole of the guide rail (8) and is further inserted into the pin hole of the pressure block (11). The position is fixed by the locking pin (10). The sliding positioning structure does not require disassembly of parts and can be adapted to lock rings (13) of different diameters, improving the versatility of the equipment. When installing lock rings (13) of different diameters, first loosen the locking pin (10), slide the pressure block (11) along the T-shaped groove of the guide rail (8) so that the bottom of the pressure block (11) fits against the end face of the lock ring (13), adjust it to the appropriate position, and then tighten the locking pin (10).

[0037] In another technical solution, the pressure block (11) includes an upper T-shaped guide block and a lower pressure block. The upper T-shaped guide block and the lower pressure block are fixedly connected, or the upper T-shaped guide block and the lower pressure block are integrally formed. The pressure block (11) slides in the guide rail (8) through the upper T-shaped guide block. By moving the pressure block (11) radially along the guide rail (8), the circumferential position of the pressure block (11) on the guide rail (8) can be adjusted to adapt to locking rings (13) of different diameters. There is no need to replace pressing parts of different specifications, which improves the equipment's versatility for different tire models and reduces tooling change time.

[0038] In another technical solution, the upper T-shaped guide block has pin holes with the same spacing as the pin holes of the guide rail (8), allowing the guide rail (8) and the pin holes of the T-shaped guide block to have multiple sliding matching points. The locking pin (10) is inserted into the pin holes of the guide rail (8) and the T-shaped guide block in sequence to fix the upper T-shaped guide block and the guide rail (8) in place. The standardized design of the pin hole spacing and diameter ensures that when the pressure block (11) is adjusted to a non-standard position, it is impossible to align all the pin holes at the same time, effectively avoiding installation deviations caused by operator error.

[0039] In another technical solution, the bottom end face of the pressure block (11) is a planar structure, which is in contact with the top surface of the lock ring (13). Due to the large contact area of ​​the planar structure, the lock ring (13) is subjected to uniform force in the circumference, and no local deformation will occur during the pressing process, thus protecting the appearance and performance of the lock ring (13). With the sliding adjustment function, the pressing force is evenly applied to the circumference of the lock ring (13), avoiding deformation caused by local stress concentration.

[0040] In another technical solution, the lifting structure includes lifting lugs (2) symmetrically welded to both sides of the upper base (1). The lifting lugs (2) are U-shaped plate structures. During welding, symmetry on both sides is ensured. The lifting lugs (2) are connected to the steel chain (6) through U-shaped buckles (3). The length of the steel chain (6) can be adjusted by tightening the bolts of the U-shaped buckles (3) to accommodate tire rim assemblies (12) of different heights. A hook (9) is installed at the lower end of the steel chain (6). The hook (9) hooks onto the preset hook hole on the top surface of the tire rim assembly (12) to ensure stable and reliable lifting. During installation, the hook (9) is first hooked onto the preset hook hole of the tire rim assembly (12). The length of the steel chain (6) is adjusted by the U-shaped buckle (3) to keep the tire rim assembly (12) horizontal. When the hydraulic jack (4) is lifted, the steel chain (6) is in a tensioned state, which evenly transmits the lifting force and prevents the tire rim assembly (12) from tilting.

[0041] In another technical solution, the cylinder body of the hydraulic jack (4) is fixed to the center of the top surface of the lower base (5), and the top end of the piston rod of the hydraulic jack (4) is fixed to the center of the bottom surface of the upper base (1). Preferably, a bolt hole is opened at the center of the top surface of the lower base (5) to fix the cylinder body of the hydraulic jack (4) with bolts, and a connecting hole is opened at the center of the bottom surface of the upper base (1) to be threadedly connected to the top end of the piston rod. The center-fixed design of the hydraulic jack (4) with the upper base (1) and the lower base (5) ensures that the lifting force is transmitted along the axis, avoids the upper base (1) from tilting, and ensures the coaxiality accuracy when the locking ring (13) is pressed.

[0042] The number of devices and processing scale described herein are for the purpose of simplifying the description of this utility model. Applications, modifications, and variations of this utility model will be readily apparent to those skilled in the art.

[0043] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
