[0002] At present, with the continuous development of my country's social economy, the number of roads is also increasing. The Chinese utility model patent, authorization announcement number "CN220183849U", discloses a slope high-efficiency buffering and energy dissipation device, including a bearing plate, a fixed column is fixedly installed on one side of the bearing plate, and buffer columns are fixedly installed on the inner wall surfaces of two groups of the fixed columns. A limiting ring is fixedly installed on one end of the two groups of the buffer columns, and a bidirectional screw is rotatably installed between the two groups of the limiting rings. A buffer plate is installed through the other end of the fixed column, and a hinged seat is fixedly installed on the back side of the buffer plate. A side support rod and an axial support rod are hingedly installed between the two groups of the hinged seats. After the falling rock hits the buffer plate, the side support rod and the axial support rod are squeezed, and the side support rod and the axial support rod will slide along the bidirectional screw against the slider to buffer the impact energy, effectively avoiding damage to the device caused by direct impact, and avoiding danger to pedestrians and vehicles.

[0003] In the above technical solution, the falling rocks first hit the steel mesh and then hit the buffer plate, which can reduce part of the kinetic energy in disguise and increase the safety of protection. After the falling rocks hit the buffer plate, the side support rods and the shaft support rods are squeezed. The side support rods and the shaft support rods will push the slider and slide along the bidirectional screw to buffer the impact energy. However, the above technical solution still has certain defects. For example, after the falling rocks hit the buffer plate, the side support rods and the shaft support rods are squeezed to buffer the impact energy. However, when the buffer plate is damaged for a long time, the staff needs to use special tools and have certain professional skills to disassemble it. This operation is complicated and difficult, which reduces the maintenance and repair efficiency of the buffer plate and reduces the practicality of the equipment. Utility Model Content

[0029] See also Figure 1-3 , the utility model provides a technical solution: a slope protection buffer energy dissipation device, comprising a support base 1;

[0030] A limiting device is provided on the supporting base 1;

[0031] The limiting device includes a buffer frame 2 and a support plate 9. The upper surfaces of the two mounting blocks at the upper end of the support plate 9 are provided with fixed block grooves 5. The outer walls of the two guide blocks at the lower end of the buffer frame 2 are respectively slidably connected to the inner sides of the corresponding fixed block grooves 5. The interiors of the two fixed block grooves 5 are slidably connected with fixed blocks 8. The outer walls of the two fixed blocks 8 are provided with push block grooves 7. The interiors of the two push block grooves 7 are provided with return springs 4. The outer walls of one end of the two fixed blocks 8 are respectively in contact with the outer walls of the guide blocks at the lower end of the corresponding buffer frame 2. The inner walls of one end of the two fixed block grooves 5 are provided with two limiting block grooves 10. The interiors of the two push block grooves 7 are slidably connected. The dynamic connection is with a push block 6, and the grooves on both sides of the two fixed blocks 8 are slidingly connected to the limiting blocks 11. The interiors of the two push block grooves 7 are respectively communicated with the interiors of the grooves on both sides of the corresponding fixed blocks 8. The two push blocks 6 are fixedly connected to the outer wall of the limiting block 11 at one end close to the limiting block 11, and the two ends of the two return springs 4 are respectively fixedly connected to the outer wall of one end of the corresponding limiting block 11. The two limiting blocks 11 slide and extend to the interior of the fixed block groove 5 at one end close to the limiting block groove 10 and are respectively slidingly connected to the interior of the corresponding limiting block groove 10. The outer wall of the support plate 9 is slidingly connected to the interior of the upper end opening of the support base 1.

[0032] Among them, six grooves are opened inside the support base 1, and the interior is fixedly connected to fixed rods 12, and the six fixed rods 12 are grouped into three. The outer walls of the two groups of fixed rods 12 are slidably connected to two movable seats 13. A damper 17 is installed inside the support base 1, and the damper 17 is fixedly connected to the lower surface of the support plate 9 at one end close to the support plate 9. The lower surface of the support plate 9 is fixedly connected with six mounting fixed blocks 16, and the six mounting fixed blocks 16 are grouped into three. The lower ends of the two groups of mounting fixed blocks 16 are rotatably connected with connecting rods 15. The outer walls of the two groups of fixed rods 12 are sleeved with buffer springs 14, and the two ends of the two groups of buffer springs 14 are respectively fixedly connected to the outer wall of one end of the corresponding movable seat 13 and the inner wall of the groove opened inside the support base 1. The ends of the two groups of connecting rods 15 close to the movable seat 13 are respectively rotatably connected to the upper end of the fixed block of the corresponding movable seat 13, and a steel mesh 3 is installed inside the upper end of the buffer frame 2.

[0033] Furthermore, when using the device, the support base 1 is first installed in the specified position. Then, when in use, the falling rock first hits the steel mesh 3 and then hits the buffer frame 2. The limit block groove 10 can reduce part of the kinetic energy in disguise, thereby increasing the safety of protection. Then, the force generated by the falling rock on the buffer frame 2 causes the support plate 9 to move downward while the force generated by it is absorbed by the damper 17. At the same time, the fixed block 16 and the connecting rod 15 are installed to cooperate to drive the moving seat 13 to move in the opposite direction. Then, the moving seat 13 moves in the opposite direction to drive the buffer spring 14 to contract while assisting the damper 17, which effectively protects the equipment. Then, when the buffer frame 2 needs to be disassembled, push the push block 6 to move the opposite ring to drive the limit block 11 to move in the opposite direction. Then, the limit block 11 moves in the opposite direction to drive the return spring 4 to contract while causing its other end to disengage from the inside of the limit block groove 10. Then, pull the fixed block 8 to remove it from the inside of the fixed block groove 5, and then pull the buffer frame 2 to remove it from the support plate 9.

[0034] By pushing the push block 6 in the limit device, the opposite moving ring drives the limit block 11 to move in the opposite direction, and then the limit block 11 moves in the opposite direction to drive the return spring 4 to contract while making the other end of it disengage from the inside of the limit block groove 10, and then pull the fixed block 8 to remove it from the inside of the fixed block groove 5, and then pull the buffer frame 2 to remove it from the support plate 9, which is convenient for the staff to disassemble the buffer frame 2, and at the same time avoids the need for the staff to use professional tools to disassemble it, thereby effectively improving the maintenance and inspection efficiency of the buffer frame 2, and the force generated by the falling rocks on the buffer frame 2 causes the support plate 9 to move downward while the force generated by it is absorbed by the damper 17, and at the same time, by installing the fixed block 16 and the connecting rod 15, the moving seat 13 is driven to move in the opposite direction, and then the moving seat 13 moves in the opposite direction to drive the buffer spring 14 to contract while assisting the damper 17, which can effectively protect the equipment, and at the same time avoid damage to the device caused by direct impact and avoid danger to pedestrians and vehicles.

[0035] Working principle: First, install the support base 1 at the specified position. Then, when in use, the falling rock first hits the steel mesh 3 and then hits the buffer frame 2. The limit block groove 10 can reduce part of the kinetic energy in disguise, thereby increasing the safety of protection. Then, the force generated by the falling rock on the buffer frame 2 causes the support plate 9 to move downward while the force generated by it is absorbed by the damper 17. At the same time, the fixed block 16 and the connecting rod 15 are installed to cooperate to drive the moving seat 13 to move in the opposite direction. Then, the moving seat 13 moves in the opposite direction to drive the buffer spring 14 to contract while assisting the damper 17. This effectively protects the equipment. Then, when the buffer frame 2 needs to be removed, push the protrusion on the limit block 11 to move in the opposite direction to drive the reset spring 4 to contract while causing its other end to disengage from the inside of the limit block groove 10. Then, pull the fixed block 8 to remove it from the inside of the fixed block groove 5. Then, pull the buffer frame 2 to remove it from the support plate 9.
