[0002] A concrete mixer truck, or mixer truck, is a special truck used to transport ready-mixed concrete for construction. Due to its appearance, it is often called a snail truck. The truck is equipped with a cylindrical mixing drum to carry the mixed concrete. During the transportation process, the mixing drum will always be kept rotating to ensure that the transported concrete will not solidify. After the concrete is transported, the inside of the mixing drum is usually rinsed with water to prevent the hardened concrete from taking up space.

The front arc-shaped anti-collision protection bar has a first slide groove on the left side of the inner side, and the front arc-shaped anti-collision protection bar has a second slide groove on the inner side. The front arc-shaped anti-collision protection bar is connected to the middle-layer anti-collision protection bar through the slide groove. A pressure-resistant groove is fixedly provided on the inner side of the middle-layer anti-collision protection bar, and a first circular boss is provided in the middle of the pressure-resistant groove.

The mounting plate 3 is provided with a mounting mechanism 5 that is convenient for connecting with the vehicle, which is convenient for installing the anti-collision structure and can adjust the length of the anti-collision structure.

[0023] The length of the mounting plate 3 is smaller than the length of the connecting plate 2 , and the height of the mounting plate 3 matches the height of the connecting plate 2 , so as to protect the structure on the vehicle head 1 .

[0024] See also Figure 2-3In order to improve the safety of the concrete transport vehicle and reduce the damage caused by collision, the anti-collision mechanism 4 in this embodiment includes a damping pad 401, which is fixed to the left side of the mounting plate 3. A spring 402 is fixed to the left side of the damping pad 401, and an anti-collision rod 403 is fixed to the other end of the spring 402. When the front of the vehicle 1 is about to collide with an obstacle, the obstacle first contacts the anti-collision rod 403, and the obstacle and the anti-collision rod 403 are squeezed to compress the spring 402 to buffer the impact caused by the collision. A rubber pad 404 is fixed to the left side of the anti-collision rod 403 to reduce the wear of the anti-collision rod 403 when it is hit, and a limit position component is set on the anti-collision rod 403.

[0025] In this example, there are two damping pads 401 , which are symmetrically distributed front to back about the central axis of the mounting plate 3 , so as to improve the buffering performance of the anti-collision rod 403 .

[0026] It should be noted that the limiting assembly includes a limiting rod 405, one end of which is fixed to the right side of the anti-collision rod 403, the anti-collision rod 403 drives the limiting rod 405 to move, the other end of the limiting rod 405 passes through and extends to the inside of the mounting plate 3, and a limiting block 406 is fixed, the limiting rod 405 drives the limiting block 406 to move, so as to limit the moving trajectory and moving range of the anti-collision rod 403, and a buffer pad 407 is fixed to the right inner wall of the mounting plate 3. When the limiting block 406 moves to the buffer pad 407, The buffer pad 407 and the spring 402 simultaneously buffer the impact on the anti-collision rod 403, thereby reducing the damage to the front of the vehicle 1. The damping pad 401 can absorb the impact generated by the squeezing of the spring 402, thereby preventing the front of the vehicle 1 from suffering secondary damage. A railing 408 is fixed to the upper surface of the mounting plate 3, and a connecting hole is opened on the left side of the mounting plate 3. The limiting rod 405 is located inside the connecting hole, and the inner diameter of the connecting hole is adapted to the outer diameter of the limiting rod 405, so that the limiting rod 405 maintains the moving track when moving.

[0027] See also Figure 4In order to facilitate the installation of the anti-collision structure and adjust the extended length of the anti-collision structure, the mounting mechanism 5 in this embodiment includes a fixing plate 501, the fixing plate 501 is fixed to the lower surface of the mounting plate 3, a sliding opening 502 is provided on the lower surface of the fixing plate 501, a pad 503 is provided below the fixing plate 501, a fastening bolt 504 is provided inside the pad 503, a threaded groove 505 is provided on the lower surface of the connecting plate 2, and the fastening bolt 504 is threadedly connected to the inner side of the threaded groove 505, The upper surface of the fixing plate 501 is fitted with the lower surface of the connecting plate 2, and then the sliding opening 502 is aligned with the threaded groove 505 on the connecting plate 2. Then, the fastening bolt 504 is placed into the pad 503 and passes through the sliding opening 502 to reach the threaded groove 505. The fastening bolt 504 is rotated to make the fastening bolt 504 and the threaded groove 505 threadedly connected. The fastening bolt 504 is tightened so that the pad 503 connects and fixes the fixing plate 501 and the connecting plate 2, thereby completing the installation of the mounting plate 3.

[0028] In this example, the width of the slide 502 is adapted to the outer diameter of the top end of the fastening bolt 504, and the outer diameter of the pad 503 is larger than the width of the slide 502, so that the fastening bolt 504 can move in the slide 502, so that the extended length of the anti-collision rod 403 can be adjusted by adjusting the position of the slide 502.

[0029] The working principle of the above embodiment is:

[0030] (1) When installing the anti-collision structure, first fit the upper surface of the fixing plate 501 with the lower surface of the connecting plate 2, then align the sliding opening 502 with the threaded groove 505 on the connecting plate 2, then put the fastening bolt 504 into the pad 503, and pass it through the sliding opening 502 to reach the threaded groove 505, rotate the fastening bolt 504 to make the fastening bolt 504 and the threaded groove 505 threadedly connected, tighten the fastening bolt 504, so that the pad 503 connects and fixes the fixing plate 501 and the connecting plate 2, thereby completing the installation of the mounting plate 3, and after loosening the fastening bolt 504, the length of the anti-collision rod 403 can be adjusted by adjusting the position of the sliding opening 502.

[0031] (2) When the front of the vehicle 1 is about to collide with an obstacle, the obstacle first contacts the anti-collision rod 403, and the obstacle and the anti-collision rod 403 are squeezed to compress the spring 402. At the same time, the anti-collision rod 403 drives the limit rod 405 to move, and the limit rod 405 drives the limit block 406 to move. When the limit block 406 moves to the buffer pad 407, the buffer pad 407 and the spring 402 simultaneously buffer the impact of the anti-collision rod 403, thereby reducing the damage to the front of the vehicle 1. The damping pad 401 can absorb the impact caused by the squeezing of the spring 402, thereby preventing the front of the vehicle 1 from suffering secondary damage.
