[0002] Dump trucks, as a commonly used engineering transport vehicle, play an important role in loading and unloading cargo. However, during operation, frequent lifting and lowering operations generate significant impact forces, which not only damage the vehicle structure but also affect its stability and safety. Therefore, a dump truck buffer device is urgently needed in the market.
[0003] However, the prior art still has the following problems:
[0004] First of all, the traditional dump truck buffer device often has a simple structure and only relies on simple springs or rubber pads for buffering. The buffering effect is limited and cannot effectively cope with large impact forces. It is easy to cause the car body to be subjected to large vibrations when returning to its position after unloading, affecting the integrity of the cargo and the service life of the vehicle.
[0005] Secondly, the traditional dump truck buffer device is not stable enough during use and lacks effective limiting and guiding structures, which makes it easy for the buffer components to shift and shake, reducing the reliability of the buffer effect and increasing safety hazards.
[0006] In response to the above problems, the inventors proposed a dump truck buffer device to solve the above problems. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] Example: Figure 1-4As shown, the utility model provides a dump truck buffer device, including a bottom plate 1, the top of the bottom plate 1 is fixedly connected to two buffer mechanisms 2, the buffer mechanism 2 includes a buffer plate 4, the buffer plate 4 and the bottom plate 1 are distributed in parallel, and the parallel distribution can ensure that the buffer plate 4 can evenly transmit the force to the bottom plate 1 when subjected to impact force, thereby improving the stability of the buffer effect, the top of the buffer plate 4 is rotatably connected to a pressure plate 7, the top of the buffer plate 4 is fixedly connected to a horizontal bar 5 used in conjunction with the pressure plate 7, and the top of the pressure plate 7 is fixedly connected to a rubber pad 6 After the carriage is unloaded, the bottom end is pressed on the pressure plate 7. The design of the rotating connection can effectively increase the life of the buffer mechanism 2. The rubber pad 6 can further buffer the impact force between the cargo and the pressure plate 7. The bottom end of the buffer plate 4 is fixedly connected to two fixed blocks 11. The two fixed blocks 11 are distributed in parallel and the sizes of the two fixed blocks 11 are the same. The inner surfaces of the two fixed blocks 11 are rotatably connected to the buffer rod 12. The other ends of the two buffer rods 12 are rotatably connected to the moving block 13. The bottom ends of the two moving blocks 13 are connected to the bottom plate together. 1 is connected to the top of the bottom plate 1 for sliding, and two limiting grooves 15 are provided at the top of the bottom plate 1. The bottom ends of the four moving blocks 13 are fixedly connected with limiting blocks 21 used in conjunction with the limiting grooves 15. The cooperation between the limiting grooves 15 and the limiting blocks 21 can ensure that the movement of the moving blocks 13 on the bottom plate 1 is more stable. The corresponding ends of the two moving blocks 13 are fixedly connected with a hydraulic rod 14. When the dump truck unloads, the lower part of the car rotates to the pressure plate 7. When it is subjected to vibration or impact, the rubber pad 6 on the pressure plate 7 will absorb part of the impact force. Then the pressure plate 7 will drive the buffer plate 4 to move downward, driving the two fixed blocks 11 fixed at its bottom end to move downward, and the fixed block 11 will push the buffer rod 12 rotatably connected thereto to rotate, and the moving block 13 connected to the other end of the buffer rod 12 slides on the bottom plate 1. When the moving block 13 slides on the bottom plate 1, the limit block 21 at its bottom end slides in the limit groove 15 at the top end of the bottom plate 1, playing the role of limiting and guiding. As the moving block 13 slides, the hydraulic rod 14 is compressed, and the liquid in the hydraulic rod 14 flows under pressure, thereby buffering the impact force.
[0022] The bottom end of the buffer plate 4 is fixedly connected to four inner rods 33, and the outer surfaces of the four inner rods 33 are slidably sleeved with the outer rod 3. The tops of the four outer rods 3 are fixedly connected to buffer pads 32. The buffer pads 32 can further reduce the impact force when the buffer plate 4 drops, protect the outer rod 3, and extend the service life of the outer rod 3. The outer surfaces of the four inner rods 33 are fixedly connected to two sliders 31, and the inner surfaces of the four inner rods 33 are provided with slide grooves 34 used to cooperate with the two sliders 31. The cooperation between the sliders 31 and the slide grooves 34 can ensure that the extension and contraction of the inner rod 33 in the outer rod 3 is smoother, reduce friction resistance, and improve the response speed of the buffer device. The bottom ends of the four inner rods 33 are fixedly connected to springs 35 The bottom ends of the four springs 35 are respectively fixedly connected to the lower inner walls of the four outer rods 3. The four outer rods 3 are distributed in a rectangular array. The fixed connection method of the springs 35 and the outer rods 3 can ensure that the springs 35 will not loosen or fall off during operation, ensuring the stable performance of the buffer device. The bottom ends of the four outer rods 3 are jointly fixedly connected to the top of the bottom plate 1. The downward movement of the buffer plate 4 will also drive the four inner rods 33 fixedly connected to its bottom end to slide in the outer rod 3. During the sliding process of the inner rod 33, the spring 35 in the outer rod 3 is compressed. The spring 35 uses its elastic deformation to further absorb and buffer the impact force. The slider 31 on the outer surface of the inner rod 33 slides in the slide groove 34 to ensure that the sliding of the inner rod 33 in the outer rod 3 is more stable and smooth.
[0023] Working principle: After the dump truck unloads, when the lower part of the car body rotates to the pressure plate 7, when it is subjected to vibration or impact force, the rubber pad 6 on the pressure plate 7 will absorb part of the impact force, and then the pressure plate 7 will drive the buffer plate 4 to move downward, driving the two fixed blocks 11 fixed at its bottom end to move downward, and the fixed block 11 in turn drives the buffer rod 12 connected to it for rotation, and the moving block 13 connected to the other end of the buffer rod 12 slides on the bottom plate 1. When the moving block 13 slides on the bottom plate 1, the limit block 21 at its bottom end slides in the limit groove 15 at the top of the bottom plate 1, playing the role of limiting and guiding. As the moving block 13 slides, the hydraulic rod 14 is compressed, and the liquid in the hydraulic rod 14 flows under the action of pressure, thereby buffering the impact force;
[0024] The downward movement of the buffer plate 4 will also drive the four inner rods 33 fixedly connected to its bottom end to slide in the outer rod 3. During the sliding process of the inner rod 33, the spring 35 in the outer rod 3 is compressed. The spring 35 uses its elastic deformation to further absorb and buffer the impact force. The slider 31 on the outer surface of the inner rod 33 slides in the slide groove 34, ensuring that the sliding of the inner rod 33 in the outer rod 3 is more stable and smooth.
[0025] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
