Description

Technical Field

[0001] This utility model relates to the technical field of highway traffic safety protection facilities, and in particular to a highway slope rockfall protection device with buffer and shock absorption function. Background Technology

[0002] Rockfall on highway slopes refers to a natural disaster phenomenon in which rock masses detach from the parent rock under the influence of gravity and roll down steep cliffs or slopes to the bottom of the highway slope. It is common in mountainous highways during the flood season. Rockfall prevention refers to protective engineering for dangerous rocks on cliffs, steep slopes, or tunnel entrances. The main methods used are gabion nets, rockfall protection nets, rockfall shelters, and curtain nets to eliminate safety threats. The design follows the principles of energy dissipation and impact reduction, and uses flexible structures for comprehensive slope management. It also needs to take into account environmental coordination and traffic safety requirements. Rockfall protection nets are widely used in railway and highway slope protection.

[0003] The existing technical solutions mentioned above have the following drawbacks: the existing slope rockfall protection equipment all rely on the installation of brackets and protective nets for protection, which has limited protective effect, cannot effectively buffer falling rocks, and cannot reduce the number of rocks sliding onto the road. Utility Model Content

[0004] The purpose of this invention is to provide a roadside rockfall protection device with buffering and shock absorption functions.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A roadside rockfall protection device with buffer and shock absorption function includes a bracket. A first hook is fixedly connected to the outside of the bracket. A waist-shaped groove is opened inside the bracket. A second hook is installed on the outside of the waist-shaped groove. A connecting block is fixedly connected to the outside of the second hook. A screw is inserted into the inside of the connecting block. A nut is installed on the outside of the screw.

[0007] By adopting the above technical solution, a first hook and a waist-shaped groove are added inside the bracket, and a structure for fixing a second hook is added inside the waist-shaped groove. The tire is hung on the outside of the first hook, and the position of the second hook is adjusted so that the second hook contacts the other side of the tire's interior, making the tire installation more stable.

[0008] Furthermore, a support rod is fixedly connected to the outside of the bracket, a base plate is fixedly connected to the outside of the support rod, expansion bolts are inserted into the inside of the base plate, a metal protective net is fixedly connected between the brackets, and a discarded tire is installed on the outside of the first hook.

[0009] By adopting the above technical solution, the support rod supports the other side of the bracket. Once a rock falls and comes into contact with the bracket, the support rod provides auxiliary support to the bracket, thereby improving the overall strength of the device.

[0010] Furthermore, the bracket, the first hook, the waist-shaped groove, the second hook, the connecting block, the screw and the nut are arranged in multiple sets at equal intervals. Each set has multiple sets of the first hook, the waist-shaped groove, the second hook, the connecting block, the screw and the nut. The screw passes through the interior of the waist-shaped groove and extends to the outside of the connecting block. The screw and the nut are threaded together.

[0011] By adopting the above technical solution and through the distribution of multiple sets of structures, the device can be laid along the outer side of the road. At the same time, the second hook is easy to install and adjust, and convenient to use.

[0012] Furthermore, the support rod, base plate, expansion bolts, metal protective net and waste tire are arranged in multiple sets at equal intervals. Each set has multiple base plates, expansion bolts and waste tires. The support rod adopts an inclined structure. The first hook and the second hook are in contact with the inner side of the waste tire. One end of the bracket and the outer side of the metal protective net adopts an inclined structure.

[0013] By adopting the above technical solution, multiple discarded tires are added to the outside of each bracket. These discarded tires can be used for buffering and protection, and the cost of using discarded tires is lower, making them more convenient to use.

[0014] In summary, the beneficial technical effects of this utility model are as follows:

[0015] The system employs a bracket, a first hook, a second hook, discarded tires, and a metal protective net. Multiple brackets and metal protective nets are combined to form a structure that blocks small falling rocks. Hooks and discarded tires are added to the brackets, allowing the discarded tires to be hung on the hooks. This allows for easy adjustment and use of the discarded tires. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1-5 A roadside rockfall protection device with buffer and shock absorption function includes a bracket 1. A first hook 2 is fixedly connected to the outside of the bracket 1. A waist-shaped groove 3 is opened inside the bracket 1. A second hook 4 is installed on the outside of the waist-shaped groove 3. A connecting block 5 is fixedly connected to the outside of the second hook 4. A screw 6 is inserted into the inside of the connecting block 5. A nut 7 is installed on the outside of the screw 6. A support rod 8 is fixedly connected to the outside of the bracket 1. A base plate 9 is fixedly connected to the outside of the support rod 8. An expansion bolt 10 is inserted into the inside of the base plate 9. A metal protective net 11 is fixedly connected between the brackets 1. A discarded tire 12 is installed on the outside of the first hook 2. The first hook 2 and waist-shaped groove 3 are added inside the bracket 1. At the same time, a structure for fixing the second hook 4 is added inside the waist-shaped groove 3. The tire is hung on the outside of the first hook 2. At the same time, the position of the second hook 4 is adjusted so that the second hook 4 contacts the other side of the inside of the tire, making the tire installation more stable. The support rod 8 supports the other side of the bracket 1. Once a rock falls and contacts the bracket 1, the support rod 8 provides auxiliary support to the bracket 1, improving the overall strength of the device.

[0024] like Figure 1-5 As shown, bracket 1, first hook 2, waist-shaped groove 3, second hook 4, connecting block 5, screw 6 and nut 7 are arranged in multiple sets at equal intervals. Each set has multiple sets of first hook 2, waist-shaped groove 3, second hook 4, connecting block 5, screw 6 and nut 7. Screw 6 passes through the inside of waist-shaped groove 3 and extends to the outside of connecting block 5. Screw 6 and nut 7 are threaded together. Support rod 8, base plate 9, expansion bolt 10, metal protective net 11 and waste tire 12 are arranged in multiple sets at equal intervals. Each set has multiple sets of base plate 9, expansion bolt 10 and waste tire 12. Support rod 8 adopts an inclined structure. First hook 2 and second hook 4 are in contact with the inside of waste tire 12. One end of the outer side of bracket 1 and metal protective net 11 adopts an inclined structure.

[0025] The implementation principle of this embodiment is as follows: The base plate 9 of the support 1 is in contact with the ground and is fixed by expansion bolts 10 to fix the bottom of the support 1. At the same time, a metal protective net 11 is added between the supports 1 to block small falling rocks. The outer side of the support 1 has a first hook 2 to hang the waste tire 12. By adjusting the second hook 4, the screw 6 can slide inside the waist groove 3 to adjust the position of the second hook 4 and make it contact the inner side of the waste tire 12. Then, the nut 7 is locked and fixed to the screw 6, and the connecting block 5 and the second hook 4 are fixed to fix multiple waste tires 12. The waste tires 12 buffer and block larger falling rocks. At the same time, the structure is easy to adjust and use, and plays a good role in buffering and protection.
