Description

Technical Field

[0001] This utility model relates to the field of excavator equipment manufacturing technology, and more specifically to a track plate that is easy to replace and assemble. Background Technology

[0002] Track shoes are chassis components of construction machinery and are considered wear parts. They are commonly used on excavators, bulldozers, tracked cranes, pavers, and other construction machinery. Since track shoes are in constant contact with the ground, they experience wear after a period of use, requiring complete removal or replacement of some track shoes. Current track shoe structures typically involve mounting articulated bumps at the bottom of the track shoe, connected by pins. These pins are secured on both sides by notched steel rings. In practice, removing the track shoe simply involves separating the articulated bumps by untying the notched steel rings, allowing for easy replacement. However, because the articulated bumps are usually located in the middle of the bottom of the track shoe, creating a blind spot, and the steel rings are small, it's inconvenient for maintenance workers to remove them with tools. This results in low track shoe replacement efficiency and often requires considerable time. In response to this, the inventor proposes a track plate that is easy to replace and assemble. By improving the pin structure, it is possible to install and disassemble the track plate more easily, thereby improving the maintenance efficiency of the equipment and thus improving the construction efficiency.

[0003] To ensure the stability of the hinged protrusions at the bottom of the track plates and prevent them from falling off during use, Chinese Patent (Authorization Announcement No.: CN218431471U) discloses a high-strength wear-resistant track plate for cranes. This utility model includes anti-slip teeth, reinforcing ribs, wear-resistant protrusions, and a web plate. The web plate has protrusions and slots on both sides, and multiple web plates are assembled by splicing them together through these protrusions and slots. The top of the web plate has multiple integrated anti-slip teeth, and the top of each anti-slip tooth has an integrated wear-resistant protrusion. The reinforcing ribs reinforce the anti-slip teeth for support and protection. This utility model facilitates the splicing and combination of multiple web plates through the protrusions and slots, and has resettable spring buckles on both sides of the protrusions. These spring buckles lock the web plates in place through the locking mechanism, providing anti-detachment protection.

[0004] This solution still has some shortcomings in application. Because the articulated protrusion is installed in the middle of the bottom of the track shoe, the space is limited, obstructing visibility. Furthermore, the small size of the pin and the use of a spring structure may lead to difficult assembly, affecting the assembly, disassembly, and replacement of the track shoe. Therefore, the structure of the track shoe needs to be improved to overcome the aforementioned limitations, making it easier for maintenance workers to install and remove the pin, thus improving the efficiency of track shoe assembly and replacement. Utility Model Content

[0005] The present invention discloses a track plate that is easy to replace and assemble, and its main purpose is to overcome the above-mentioned deficiencies and disadvantages of the prior art.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A track plate that is easy to replace and assemble includes a track plate, a hinge protrusion, and a first pin. The track plate has a waist-shaped hole in the middle, and fastening bolts are provided on both sides of the waist-shaped hole. The hinge protrusion is fixed to the middle of the bottom of the track plate by the fastening bolts. The hinge protrusion has a head-to-tail connection structure and a through hole in between. The first pin passes through the through hole and a fixing nut is screwed to its end. The fixing nut is located on the outward side of the track plate.

[0008] Furthermore, the hinged protrusion includes a front protrusion and a rear protrusion, with a second pin between the front protrusion and the rear protrusion, and the front protrusion and the rear protrusion are hinged together.

[0009] Furthermore, shock-absorbing rubber sleeves are provided on both sides of the first pin shaft, and the shock-absorbing rubber sleeves have a groove on the outward side, and the fixing nut is adapted to be embedded in the groove on one side.

[0010] Furthermore, the first pin has an external thread on one side.

[0011] Furthermore, the fixing nut is provided with a threaded hole, which is adapted to be screwed into the external thread, and a hexagonal external nut is provided on the outside of the threaded hole.

[0012] Furthermore, the first pin has a through hole in the middle and a limiting ring on one side inward.

[0013] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0014] This invention improves the pin structure connecting the hinge protrusions at the bottom of the track plate by replacing the existing notched ring with a fixing nut with a hexagonal nut. The fixing nut secures one side of the pin, facilitating subsequent assembly and replacement. Furthermore, while the existing notched ring provides structural stability, its small size and the confined space at the bottom center of the track plate make installation and removal difficult for maintenance workers, often requiring lifting the track plate for operation, which is time-consuming and labor-intensive. Finally, shock-absorbing rubber sleeves are provided on both sides of the pin to improve its sealing performance, preventing dirt from entering and causing rotational failure. The fixing nut is also partially embedded in the shock-absorbing rubber sleeves to prevent deformation from impacts. This invention features a novel and ingenious design, facilitating assembly and replacement, and is suitable for track use. Attached Figure Description

The hinge protrusion 2 is fixed to the middle of the bottom of the track plate 1 by the fastening bolts 12. The hinge protrusion 2 has a head-to-tail connection structure and a through hole in between. The first pin 3 passes through the through hole and a fixing nut 4 is screwed to its end. The fixing nut 4 is located on the outward side of the track plate 1.

[0020] Furthermore, the hinged protrusion 2 includes a front protrusion 21 and a rear protrusion 22, with a second pin 5 provided between the front protrusion 21 and the rear protrusion 22, and the front protrusion 21 and the rear protrusion 22 forming a hinged structure.

[0021] Furthermore, the first pin 3 is provided with shock-absorbing rubber sleeves 6 on both the left and right sides, and the shock-absorbing rubber sleeves 6 have a groove 7 on the outward side, and the fixing nut 4 is adapted to be embedded in the groove 7 on one side.

Then, the two track plates 1 are installed by connecting the two hinge protrusions 2. The first pin 3 passes through the hole between the two hinge protrusions 2 from the inside. Shock-absorbing rubber sleeves 6 are installed on both sides of the first pin 3. Then, the fixing nut 4 is tightened to the external thread 31 of the first pin 3 and 1 / 2 is built into the groove 7 of the shock-absorbing rubber sleeve 6 to fix the first pin 3. Finally, when it is necessary to disassemble the track plate 1, the fixing nut 4 is put on the outside by using an external tool, the fixing nut 4 is unscrewed, and the first pin 3 is struck inward to separate the hinge protrusions 2, thereby realizing the disassembly and replacement of the track plate 1, which is very convenient.

[0026] As can be seen from the above description of this utility model, compared with the prior art, the advantages of this utility model are as follows:

[0027] This invention improves the pin structure connecting the hinge protrusions at the bottom of the track plate by replacing the existing notched ring with a fixing nut with a hexagonal nut.
