Description

Technical Field

[0001] This utility model relates to the field of cable car technology, specifically a tracked engineering machinery cable car. Background Technology

[0002] Tracked construction machinery operates in harsh environments, typically large-scale infrastructure projects, open-pit metal mines, or coal mines. The tracks are in direct contact with the ground and are frequently subjected to wear and erosion from mud, sand, rocks, and ore. In particular, the impact and localized loads caused by uneven transmission and uneven ground make the tracks one of the most easily damaged parts of the entire bulldozer. Compared to other components, the track roller is positioned higher, experiences less stress, and has better working conditions. However, as one of the main components of the tracked walking system, wear is also the primary cause of failure for the track roller, requiring very frequent replacement.

[0003] The main components of a track roller are the track roller, track roller shaft, track roller cover, float seal seat, tapered roller bearing, sealing ring, and retaining ring. In existing track roller structures, the track roller is generally formed by integral casting or welding, and then subjected to integral heat treatment. Therefore, regardless of the process used, the track roller is a single unit during use. When the track roller experiences wear failure, due to the influence of maintenance personnel's skills, tooling, and working environment, the entire track roller can only be replaced, resulting in a large amount of waste. Utility Model Content

[0004] The purpose of this utility model is to address the problem that tracked engineering machinery tracked chains are mainly composed of a tracked wheel, a tracked wheel shaft, a tracked wheel cover, a float seal seat, tapered roller bearings, sealing rings, and retaining rings. In existing tracked chain structures, the tracked wheel is generally formed by integral casting or welding, and then subjected to integral heat treatment. Therefore, regardless of the process used, the tracked wheel is a single unit during use. When the tracked wheel experiences wear and tear, due to the limitations of maintenance personnel's skills, tooling, and working environment, the entire tracked chain must be replaced, resulting in significant waste. This utility model provides a tracked engineering machinery tracked chain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tracked engineering machinery drag chain wheel, comprising a drag chain wheel body, a drag chain wheel rim at one end of the drag chain wheel body, and the drag chain wheel rims being symmetrically arranged at both ends of the drag chain wheel body; a drag chain wheel shaft at one end of the drag chain wheel body; mounting shafts being symmetrically fixedly installed at both ends of the drag chain wheel body, and the mounting shafts being engaged and fixedly connected to the drag chain wheel rim; an arc-shaped groove being formed at one end of the drag chain wheel body and being engaged and fixedly connected to the drag chain wheel rim, and the arc-shaped groove being evenly formed around one end of the drag chain wheel body; and an L-shaped locking block being evenly formed around and fixedly installed at one end of the drag chain wheel rim, and the L-shaped locking block being rotatably engaged and fixedly connected to the arc-shaped groove.

[0006] As a further embodiment of this utility model: a guide groove is provided at one end of the mounting shaft, a rotating groove is provided at the other end of the mounting shaft, and the rotating groove is connected to the guide groove. The guide groove is symmetrically provided on the outer periphery of the mounting shaft. Guide blocks are uniformly and fixedly installed around the inner side of the rim of the drag chain wheel, and the guide blocks are slidably adapted to the guide groove.

[0007] As a further improvement of this utility model: the rotating groove has an empty groove inside, and a limit block is slidably connected inside the empty groove.

[0008] As a further embodiment of this utility model: a pulling block is slidably connected to one end of the mounting shaft, a connecting rod is fixedly installed at one end of the limiting block, and the connecting rod is connected through the slot, and the connecting rod is fixedly installed with the pulling block.

[0009] As a further improvement of this utility model: a reset spring is fixedly installed inside the hollow groove, and the reset spring is sleeved on the outer periphery of the connecting rod.

[0010] As a further improvement of this utility model, a pulling groove is provided at one end of the pulling block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the guide block and guide groove work together to ensure accurate installation and reduce offset and shaking; the L-shaped locking block and the arc-shaped groove rotate and engage to achieve initial circumferential positioning; the limit block locks to prevent loosening and falling off. When replacing, the limit block is pulled out by pulling the block to easily release the lock, and disassembly can be completed by reverse rotation and sliding. The whole process is simple to operate, accurate in positioning, and stable in connection, effectively improving the efficiency of installation and replacement and the reliability of equipment. By separating the drag chain wheel rim from the drag chain wheel body, the drag chain wheel body can be quickly replaced when it is worn, reducing the need to replace the entire drag chain wheel and causing a lot of waste.

The embodiments of this utility model will be described below based on its overall structure.

[0020] Reference Figures 1 to 4 In this embodiment of the utility model, a tracked engineering machinery drag chain wheel includes a drag chain wheel body 1, a drag chain wheel rim 2 is provided at one end of the drag chain wheel body 1, and the drag chain wheel rim 2 is symmetrically arranged at both ends of the drag chain wheel body 1. A drag chain wheel shaft 3 is provided at one end of the drag chain wheel body 1. Mounting shafts 4 are symmetrically fixedly installed at both ends of the drag chain wheel body 1, and the mounting shafts 4 are snapped and fixed to the drag chain wheel rim 2. An arc-shaped groove 5 is opened at one end of the drag chain wheel body 1 to snap and fix to the drag chain wheel rim 2, and the arc-shaped groove 5 is evenly opened around one end of the drag chain wheel body 1. An L-shaped locking block 6 is evenly fixedly installed around one end of the drag chain wheel rim 2, and the L-shaped locking block 6 is rotatably snapped and fixed to the arc-shaped groove 5.

[0021] The above solution is adopted: the two ends of the drag chain wheel body 1 are symmetrically fixed with mounting shafts 4, and the mounting shafts 4 are tightly engaged with the drag chain wheel rim 2. Multiple arc-shaped grooves 5 are evenly and circumferentially opened at one end of the drag chain wheel body 1, which is like a delicate groove track. At the other end of the drag chain wheel rim 2, L-shaped locking blocks 6 are evenly and circumferentially fixed. These L-shaped locking blocks 6 can accurately engage with the arc-shaped grooves 5 to ensure that the drag chain wheel rim 2 and the wheel body are tightly connected and work together during operation to ensure the stable operation of the tracked construction machinery.

[0022] Reference Figures 1 to 4 One end of the mounting shaft 4 is provided with a guide groove 7 and the other end of the mounting shaft 4 is provided with a rotating groove 8, and the rotating groove 8 is connected to the guide groove 7. The guide groove 7 is symmetrically opened on the outer periphery of the mounting shaft 4. The guide block 9 is uniformly and fixedly installed around the inner side of the drag chain wheel rim 2, and the guide block 9 is slidably adapted to the guide groove 7.

[0023] The above solution is adopted: a guide groove 7 is carefully opened at one end of the mounting shaft 4. Its shape is regular and symmetrically distributed along the outer periphery of the mounting shaft 4. At the same end, a rotating groove 8 is also precisely opened and cleverly connected with the guide groove 7. The guide groove 7 provides a guiding direction for the installation of the drag chain wheel rim 2. Multiple guide blocks 9 are evenly fixed around the inner side of the drag chain wheel rim 2. Their shapes fit the guide groove 7. When the installation operation is performed, the guide blocks 9 can slide smoothly along the guide groove 7. The fit is excellent and effectively ensures the accuracy and stability of the installation process of the drag chain wheel rim 2.

[0024] Reference Figures 1 to 4 The rotating groove 8 has an empty groove 10 inside, and a limit block 11 is slidably connected inside the empty groove 10. A pulling block 13 is slidably connected to one end of the mounting shaft 4. A connecting rod 12 is fixedly installed at one end of the limit block 11, and the connecting rod 12 is connected through the empty groove 10. The connecting rod 12 is fixedly installed to the pulling block 13. A return spring 14 is fixedly installed inside the empty groove 10, and the return spring 14 is sleeved on the outer periphery of the connecting rod 12. A pulling groove 15 is opened at one end of the pulling block 13.

[0025] Using the above scheme: the pull block 13 at one end of the mounting shaft 4 can slide flexibly, the limiting block 11 is firmly connected to the pull block 13 through the connecting rod 12, the connecting rod 12 passes through the slot 10, and the return spring 14 is fixed in the slot 10. It is tightly sleeved on the outer circumference of the connecting rod 12. When the pull block 13 is pulled, the pull block 13 drives the limiting block 11 to slide in the slot 10 through the connecting rod 12, while compressing the return spring 14. The pull groove 15 at one end of the pull block 13 is convenient for tool or manual operation, and facilitates the adjustment of the position of the limiting block 11.

[0026] The working principle of this utility model is as follows: The drag chain wheel body 1 is placed horizontally, with the mounting shafts 4 and arc-shaped grooves 5 at both ends of the drag chain wheel body 1 in a ready-to-install state. The drag chain wheel rim 2 is brought close to one end of the drag chain wheel body 1, so that the guide blocks 9, which are evenly and fixedly installed around the inner side of the drag chain wheel rim 2, are aligned with the guide grooves 7 symmetrically opened on the outer periphery of the mounting shafts 4. The guide blocks 9 are slid along the guide grooves 7. At this time, the guide grooves 7 play a guiding role, ensuring that the drag chain wheel rim 2 can accurately approach the drag chain wheel body 1. Furthermore, during the sliding process, the drag chain wheel rim... 2. No offset or shaking will occur. When the guide block 9 slides to the end of the guide groove 7, the L-shaped locking block 6, which is uniformly and fixedly installed around one end of the drag chain wheel rim 2, corresponds to the arc-shaped groove 5, which is uniformly and uniformly opened around one end of the drag chain wheel body 1. Rotating the drag chain wheel rim 2 causes the L-shaped locking block 6 to rotate and lock into the arc-shaped groove 5. This step completes the initial positioning of the drag chain wheel rim 2 in the circumferential direction. As the guide block 9 slides along the guide groove 7, the operator pulls the pulling block 13 through the pulling groove 15, causing the limiting block 11 to slide within the empty groove 10. When the drag chain wheel rim 2 rotates to the same position as the limit block 11, the operator releases the pull block 13. The limit block 11, under the elastic force of the return spring 14, pops out and enters the limit groove at one end of the guide block 9 for limiting and fixing, thereby locking the drag chain wheel rim 2 in the axial and circumferential directions to prevent it from loosening or falling off during operation. When the drag chain wheel rim 2 wears, the pull block 13 is pulled by a tool or manually through the pull groove 15 at one end of the pull block 13. 3. The connecting rod 12 is fixedly connected to the limiting block 11. Therefore, when the pulling block 13 is pulled, the limiting block 11 will slide in the empty groove 10, compress the reset spring 14, and make the limiting block 11 exit from the limiting groove at one end of the guide block 9, thereby releasing the lock on the drag chain wheel rim 2. Then, the drag chain wheel rim 2 is rotated in the opposite direction to separate the L-shaped locking block 6 from the arc groove 5. Finally, the drag chain wheel rim 2 is slid along the direction of the guide groove 7, so that the guide block 9 slides out along the guide groove 7, and finally the drag chain wheel rim 2 is removed from the drag chain wheel body 1.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
