Description

Technical Field

[0001] This utility model relates to the field of lifting tools, and in particular to a lifting tool for the drive wheel of a tracked bulldozer. Background Technology

[0002] Bulldozers are one of the main engineering machinery equipment in the German copper mine. They are mainly responsible for the development and maintenance of roads in the mining area and the implementation of various projects. The drive wheel of this type of equipment is the core component of the tracked bulldozer's walking system. The drive wheel receives the power of the engine through the transmission system (such as the gearbox and final drive), converts it into rotational motion, drives the track chain to mesh and rotate in a cycle, thereby propelling the bulldozer forward or backward.

[0003] The drive wheels are installed at the rear of the bulldozer, between the diesel tank platform and the traveling frame. They have an outer diameter of 85cm, weigh approximately 240kg, and are about 1.6m off the ground. There is one on each side. This makes it impossible to lift the drive wheels vertically during maintenance. First, the tracks and drive gears must be disassembled. Then, a crane and forklift are used for loading and unloading. This loading and unloading method is time-consuming and labor-intensive, requiring multiple people to assist in the work. Furthermore, the center of gravity is unstable during assembly, making it easy to bump into parts such as the fuel tank platform. Maintenance safety and quality cannot be guaranteed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lifting tool for the drive wheels of tracked bulldozers, which solves the technical problems of traditional loading and unloading requiring disassembly of the tracks and drive blocks and coordination with overhead cranes and forklifts, which is time-consuming, labor-intensive, and requires multiple people to assist, and also suffers from unstable center of gravity, easy collision with the fuel tank platform, and lack of safety and quality assurance.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lifting tool for the drive wheel of a tracked bulldozer includes an I-beam frame, an adjusting arm, adjusting bolts, adjusting nuts, a fixing plate, fixing plate bolts, and fixing plate nuts. The I-beam frame is welded from two rectangular hollow steel bars and one solid square steel bar. A cover plate is welded to the side of the hollow steel bar at the bottom of the I-beam frame. The cover plate has a 22mm diameter circular hole in the middle for the adjusting bolt to pass through. The adjusting arm is a rectangular hollow steel bar with an outer diameter slightly smaller than the inner diameter of the hollow steel bar of the I-beam frame so that it can be inserted into the hollow steel bar of the I-beam frame. The arm is 60cm long, which solves the problem that traditional drive wheel lifting cannot be vertically lifted due to structural limitations.

[0007] Preferably, a cover plate is welded to one end of the adjusting arm that is inserted into the hollow steel of the I-beam. The cover plate has a circular hole with a diameter of 22mm in the center. The adjusting nut is welded above the circular hole to facilitate the adjustment of the extension and retraction of the adjusting arm by the matching of the adjusting bolt and the adjusting nut, thereby improving the adaptability of the lifting tool to complex working environments.

[0008] Preferably, the other end of the adjusting arm is provided with a cover plate, which has a circular hole with a diameter of 27mm, and an M25 nut is welded to the surface of the circular hole to fix the plate, ensuring the stability of the hoisting and providing a reliable connection support for the vertical lifting of the drive wheel.

[0009] Preferably, the end of the fixing plate is provided with a shackle mounting hole, the size of which is larger than the assembly size of the 3 / 4 ton shackle, ensuring the stability of the connection between the shackle and the fixing plate and the drive wheel, and reducing safety hazards during the hoisting process.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. This lifting tool, consisting of an I-beam frame, an adjusting arm, and a fixed plate, forms a single surface, ensuring that the drive wheel is lifted vertically without swaying, thus solving the problem of unstable center of gravity in traditional lifting methods.

[0012] Second, this lifting tool has a simple structure and is easy to operate. It can avoid the oil tank jamming position by adjusting the extension and retraction of the boom, which improves the accuracy, safety and loading and unloading efficiency of the drive wheel assembly and overcomes the shortcomings of traditional methods that are time-consuming, labor-intensive and prone to collisions.

[0017] This application provides a lifting tool for the drive wheels of a tracked bulldozer, which effectively solves the problems of traditional loading and unloading methods that require disassembling the tracks and drive teeth and coordinating with a crane or forklift, which is time-consuming, labor-intensive, and requires multiple people to assist. It also suffers from unstable center of gravity, easy collision with the fuel tank platform, and lack of safety and quality assurance. This lifting tool, with its I-beam frame, adjusting arm, and fixed plate forming a single surface, can ensure that the drive wheels are lifted vertically without swaying, thus solving the problem of unstable center of gravity in traditional lifting methods. Example

[0018] like Figure 1 and Figure 2 As shown, the technical solution in this application embodiment effectively solves the technical problems of traditional loading and unloading requiring disassembly of tracks and drive gears and coordination with overhead cranes and forklifts, which is time-consuming, labor-intensive, and requires multiple people to assist. It also suffers from unstable center of gravity, susceptibility to collisions with the fuel tank platform, and lack of safety and quality assurance. The overall concept is as follows: A lifting tool for the drive wheel of a tracked bulldozer includes an I-beam frame 1, an adjusting arm 2, adjusting bolts 3, adjusting nuts 4, a fixing plate 5, fixing plate bolts 6, and fixing plate nuts 7; the I-beam frame 1 consists of two rectangular hollow steel bars and one solid square steel bar. The structure is welded together. The hollow steel at the bottom of the I-beam 1 has a cover plate welded to its side. The cover plate has a 22mm diameter hole in the middle for the adjusting bolt 3 to pass through. The adjusting arm 2 is a rectangular hollow steel bar with an outer diameter slightly smaller than the inner diameter of the hollow steel of the I-beam 1 so that it can be inserted into the hollow steel of the I-beam 1. The length is 60cm, which realizes the flexible insertion and extension of the adjusting arm 2 in the I-beam 1. This solves the problem that traditional drive wheel hoisting cannot be lifted vertically due to structural limitations, and lays a structural foundation for subsequent precise adjustment and stable hoisting.

[0019] One end of the adjusting arm 2 inserted into the hollow steel of the I-beam 1 is welded with a cover plate. The center of the cover plate has a circular hole with a diameter of 22mm. The adjusting nut 4 is welded above the circular hole to facilitate the adjustment of the extension and retraction of the adjusting arm 2 by the cooperation of the adjusting bolt 3 and the adjusting nut 4. This design can effectively adjust the longitudinal depth when the drive wheel is vertically hoisted, thereby avoiding the jamming of the bulldozer's fuel tank platform, solving the problem of easy collision with the fuel tank due to space limitations in traditional hoisting, and improving the adaptability of the hoisting tool to complex working environments.

[0020] The other end of the adjusting arm 2 is provided with a cover plate, which has a round hole with a diameter of 27mm and an M25 nut welded to the surface of the round hole to fix the fixing plate 5. This design avoids the drive wheel from shaking due to loose connection during the hoisting process, further ensuring the stability of the hoisting and providing reliable connection support for the vertical lifting of the drive wheel.

[0021] The fixed plate 5 has a shackle mounting hole at one end. The size of the shackle mounting hole is larger than the assembly size of the 3 / 4 ton shackle, which simplifies the connection process between the lifting tool and the drive wheel. It eliminates the need for the complex coordination of the overhead crane and forklift in the traditional method, improves the ease of operation, ensures the stability of the connection between the shackle and the fixed plate 5 and the drive wheel, reduces safety hazards during the lifting process, and further improves the safety of the drive wheel lifting.

[0022] To address the problems existing in the prior art, this utility model provides a lifting tool for the drive wheel of a tracked bulldozer. This lifting tool, consisting of an I-beam frame, an adjusting arm, and a fixing plate forming a single surface, ensures that the drive wheel is lifted vertically without swaying, thus solving the problem of unstable center of gravity in traditional lifting methods.

[0023] Working principle:

[0024] The first step is to remove a set of drive teeth from the drive wheel and use the original drive teeth mounting holes on the drive wheel to provide a suitable position for connecting the lifting tool to the drive wheel.

[0025] The second step is to fix the fixing plate 5 to the M25 nut at the other end of the adjusting arm 2 using the fixing plate bolt 6 and fixing plate nut 7.

[0026] The third step is to install the shackle in the shackle mounting hole at the end of the fixed plate 5, and connect the fixed plate 5 and the drive wheel through the shackle to achieve a stable connection between the lifting tool and the drive wheel.

[0027] The fourth step is to rotate the adjusting bolt 3 to engage with the adjusting nut 4 on the adjusting arm 2, thereby causing the adjusting arm 2 to extend and retract within the hollow steel of the I-beam 1, thus adjusting the longitudinal depth during vertical hoisting, avoiding the jamming of the bulldozer's fuel tank platform, and ensuring an unobstructed hoisting path.

[0028] Fifth step: Connect the wire rope to the I-beam 1 and lift it using a crane; after hoisting into place, remove the shackles, move the hoisting tools, and complete the hoisting operation of the drive wheel.

[0029] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
