[0019] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0020] like Figures 1 to 7 As shown, an anti-tipping mechanism for a self-propelled track device includes a connecting rod 1. One end of the connecting rod 1 is fixedly connected to a movable block 2, and the bottom surface of the movable block 2 is provided with track rollers 3. The other end of the connecting rod 1 is rotatably connected to a vertical roller 4. Corresponding to the vertical roller 4, a clamping block 5 is provided on the connecting rod 1. At the bottom end of the clamping block 5, a hook block 6 is connected to the hook block 6 via a reset mechanism. A horizontal roller 7 is rotatably provided at the end of the hook block 6. The vertical roller 4 contacts the top surface of the track, and the horizontal roller 7 contacts the inner wall of the track. A roller groove 8 is opened at the bottom of the movable block 2, and two track rollers 3 are rotatably installed in the roller groove 8.
[0021] In this embodiment, the reset mechanism includes a central shaft 9, a concave reset shaft 10, a convex reset shaft 11, a reset spring 12, a sliding key 13, and a reset sleeve 14. A blind hole is formed at the bottom end of the clamping block 5, and the reset sleeve 14 is fixedly disposed within this blind hole. The convex reset shaft 11 and the concave reset shaft 10 are movably disposed within the reset sleeve 14. A reset spring 12 is disposed between the top surface of the convex reset shaft 11 and the inner top surface of the reset sleeve 14. A sliding groove 15 is formed on the side wall of the convex reset shaft 11, and a limiting groove 16 is formed on the reset sleeve 14 corresponding to the sliding groove 15. The sliding key 13 is fitted within the limiting groove 16, and the sliding key 13 slides within the sliding groove 15. The end of the hook block 6 is rotatably fitted with the bottom end of the central shaft 9. The bottom end of the concave reset shaft 10 is fixedly connected to the hook block 6, and the top end of the central shaft 9 is fixedly connected to the reset sleeve 14. Both the concave reset shaft 10 and the convex reset shaft 11 are movably sleeved on the central shaft 9.
[0022] In this embodiment, the top end of the concave reset shaft 10 is provided with a V-shaped groove 17, and the bottom end of the convex reset shaft 11 is provided with a corresponding V-shaped protrusion 18, which is movably fitted within the V-shaped groove 17.
[0023] During operation, connecting rod 1 connects to the traveling device, track roller 3 engages with the top surface of one rail 19, vertical roller 4 engages with the top surface of another rail 19, and horizontal roller 7 contacts the inner wall of rail 19. When the traveling device tilts inward, vertical roller 4 provides support; when the traveling device tilts outward, hook block 6 hooks onto the lower edge of the rail head of rail 19. Therefore, this mechanism can prevent the traveling device from tilting inward or outward from the rail.
[0024] During the operation of the traveling equipment, the hook block 6 will collide with other accessories of the rail 19. If the hook block 6 is fixedly connected to the clamping block 5, it will interfere with the operation of the traveling equipment. Therefore, the hook block 6 is connected to the clamping block 5 by a reset mechanism.
[0025] When hook block 6 collides with an obstacle, it rotates, causing the concave reset shaft 10 to rotate around the central axis 9 within the reset sleeve 14. At this time, the concave reset shaft 10 and the convex reset shaft 11 are misaligned, generating an upward force that pushes the convex reset shaft 11 upward. Due to the restriction of the sliding key 13, the convex reset shaft 11 only moves upward and does not rotate. The upward-pushing convex reset shaft 11 compresses the reset spring 12, generating a reverse pressure. After hook block 6 passes the obstacle, the reset spring 12 pushes the convex reset shaft 11 downward, causing the convex reset shaft 11 to push the concave reset shaft 10 back to its initial position, thereby resetting hook block 6.
[0026] Similarly, it should be understood that, in order to simplify this disclosure and aid in understanding one or more of the various aspects of the invention, in the above description of exemplary embodiments of the invention, various features of the invention are sometimes grouped together in a single embodiment, figure, or description thereof.
