Description

Technical Field

[0001] This utility model relates to the field of polyurethane track plate technology, and more specifically, to an easily detachable polyurethane track plate. Background Technology

[0002] Polyurethane track pads are track pads made primarily of polyurethane through a specific process. They possess advantages such as high strength, high elasticity, wear resistance, tear resistance, shock absorption and noise reduction, and corrosion resistance, enabling them to adapt to various complex working conditions. Compared to traditional metal or rubber track pads, they have unique advantages in certain specific fields such as agricultural machinery and small construction machinery.

[0003] Polyurethane track shoes are mainly composed of a metal frame and polyurethane material. The metal frame provides support and connection, ensuring strength; the polyurethane material covers the surface, providing wear resistance, tear resistance, and shock absorption. During operation, mechanical power is transmitted through the metal frame, while the polyurethane surface contacts the ground, utilizing its properties to buffer vibrations and provide traction, achieving smooth movement.

[0004] In the existing technology, some easily detachable polyurethane track plates are still fixed with traditional bolts. This cannot ensure the tightness of the connection while quickly installing with bolts. During long-term use after installation, vibration will occur. Continuous vibration will gradually reduce the preload of the bolts, causing the threaded connection to loosen and affecting the connection stability between the track plate and the equipment.

[0023] As attached Figure 1To be continued Figure 5 An embodiment of this utility model provides an easily detachable polyurethane track plate, including...

[0024] The inner wall of the track plate 1 has threaded holes 2. This design allows the bolts 3 to be tightly connected to the track plate 1 via threaded connection, providing a basis for the connection between the track teeth 5 and the track plate 1. The bolts 3 are threaded inside the threaded holes 2. After the bolts 3 are screwed into the threaded holes 2, they firmly fix the track teeth 5 to the track plate 1, ensuring the stability of the entire track structure. Multiple L-shaped locking blocks 4 are movably connected to the inner wall of the bolts 3. During the installation of the bolts 3, the L-shaped locking blocks 4 play a crucial role in preventing the bolts 3 from loosening or falling off due to vibration. The track teeth 5 are threaded on the outside of the bolts 3. Through the connection of the bolts 3, the track teeth 5 can... It is easy to install on the track plate 1 and can be easily disassembled when replacement is needed; multiple positioning blocks 6 are fixedly connected to the inner wall of the track tooth 5. The positioning blocks 6 can accurately cooperate with the positioning grooves 7 on the track plate 1 during installation to ensure the accuracy of the installation position of the track tooth 5; multiple positioning grooves 7 are opened on the outside of the track plate 1. The positioning grooves 7 cooperate with the positioning blocks 6 to make the installation of the track tooth 5 and the track plate 1 more precise and improve the installation efficiency; multiple limiting grooves 8 are opened on the inner wall of the track tooth 5. The limiting grooves 8 cooperate with the protrusions on the outside of the track plate 1 to further limit the relative position of the track tooth 5 and the track plate 1 and enhance the stability of the connection.

[0025] The fixing component includes a support plate 9, which supports the connection between the track teeth 5 and the track plate 1. Since the track plate 1 is made of polyurethane, the support plate 9 enhances its structural strength. The support plate 9 is externally slidably connected to the inner wall of the track teeth 5. This sliding connection allows the support plate 9 to be smoothly installed inside the track teeth 5. The inner wall of the support plate 9 is provided with multiple support blocks 10, which further enhance the support capacity of the support plate 9 and ensure the stability of the entire fixing component. The inner wall of the support plate 9 is provided with stabilizing blocks 11, which improve the stability of the support plate 9 inside the track plate 1 and prevent it from shaking.

[0026] The support plate 9 is externally fixedly connected to the inner wall of the track plate 1. This connection method allows the support plate 9 to form an integral whole with the track plate 1, thus better fulfilling its supporting function. The end of the support block 10 away from the support plate 9 is fixedly connected to the inner wall of the track plate 1. Both ends of the support block 10 are fixedly connected to the support plate 9 and the track plate 1, respectively, further enhancing the stability of the entire structure.

[0027] The external locating block 6 is movably connected to the inner wall of the locating groove 7. The cooperation between the locating block 6 and the locating groove 7 can quickly and accurately determine the position of the track tooth 5 when it is installed, thus improving the installation efficiency. The external locating plate 1 is movably connected to the inner wall of the limiting groove 8. The cooperation between the limiting groove 8 and the track plate 1 restricts the relative movement of the track tooth 5 and the track plate 1, thus ensuring the stability of the track structure.

[0028] The external thread of bolt 3 is connected to the inner wall of support block 10. This connection method allows bolt 3 to interact with support block 10 while fixing track teeth 5 and track plate 1, further enhancing the stability of the connection. The external thread of bolt 3 is connected to the inner wall of track plate 1. The threaded connection between bolt 3 and track plate 1 is a key step in fixing track teeth 5 and track plate 1, ensuring the robustness of the entire track structure.

[0029] The external fixed connection of the stabilizing block 11 is to the inner wall of the track plate 1. The stabilizing block 11 is fixed to the inner wall of the track plate 1 to enhance the stability of the support plate 9, thereby improving the reliability of the entire fixing assembly. The external movable connection of the L-shaped locking block 4 is to the inner wall of the track tooth 5. During the rotation and downward movement of the bolt 3, the L-shaped locking block 4 will be gradually squeezed in the gap between the threaded hole 2 and the bolt 3, so that the bolt 3 is firmly fixed inside the threaded hole 2, preventing the bolt 3 from falling off due to vibration, and also facilitating quick disassembly when needed.

[0030] The working process of this utility model is as follows:

[0031] First, the track plate 1 is aligned with the track teeth 5 and placed, with the positioning groove 7 aligned with the positioning block 6 and the limiting groove 8 aligned with the protrusion on the outside of the track plate 1 and closed. Then, it is fixed by rotating the bolt 3. The bolt 3 passes through the track teeth 5 and is brought into the threaded hole 2 in the track plate 1. The thread of the threaded hole 2 is set inside the support block 10, and the support plate 9 is connected to the stabilizing block 11 inside the track plate 1. Because the track plate 1 is made of polyurethane, the support plate 9 provides support inside it. When the bolt 3 is rotated, as the bolt 3 rotates and moves down, the L-shaped locking block 4 is gradually squeezed in the gap between the threaded hole 2 and the bolt 3, so that the bolt 3 is firmly fixed inside the threaded hole 2, preventing it from falling off due to vibration and enabling quick disassembly.
