Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a highway engineering protection system, which overcomes the deficiencies of the prior art, has a reasonable design and a compact structure, and aims to solve the problem that although there are guardrails or protective devices on the existing roads, Poor stability and low structural strength cannot effectively prevent out-of-control vehicles from buffering kinetic energy and potential energy. Once a collision occurs, the vehicle will be damaged, and the personnel in the vehicle will also suffer casualties.

Embodiment 1

[0032] A highway engineering protection system, comprising a housing 1 towards the opening of the side of the highway, the lower end of the housing 1 is installed with a plurality of support rods 4, and the lower end of the support rod 4 is integrally formed with a mount 5, the mount 5 is fixed on the ground by expansion bolt 6, effectively ensuring that the protective device is fixed on both sides of the highway for vehicle safety protection, the opening side of the housing 1 is fixed through the membrane frame sleeve 3 fixed with a rubber film 2, and the inner cavity of the housing 1 is integrally molded with two separators set parallel to the rubber film 20 , and the separator 10 divides the inner cavity of the housing 1 from the opening side to the inside into a first liquid cavity 11, a second liquid cavity and a hollow cavity, the first liquid cavity 11 is a matrix distribution of a plurality of polyurethane shock absorbing layers 13, and the polyurethane shock absorbing lay...

Embodiment 2

[0044] The difference between the present embodiment and Example 1 is, e.g., Figure 1-3 As shown, the two teeth on the bottom wall of the lower side of the straight rack 17 mesh with a downward flipping gear 181, and the downward flip gear 181 is fixed mounted on the same lower flip shaft 191, both ends of the lower flip shaft 191 are mounted on the lower part of the outer wall of the housing 1 back from the rubber film 2 side by turning the lower part of the housing 1, the lower flip shaft 191 is vertically mounted on one side of the housing 1 8, after the rubber film 2 is deformed, the hydraulic oil within the first liquid cavity 11 is pressed into the two hydraulic cylinders located on the lower side 14 , and push the two third pistons on the lower side 15 to the right, and then push the lower side of the two straight rack 17 to the right movement, push the downward flip gear 181 clockwise flip, through the down flip shaft 191 to drive the support column 8 to flip, the support...

Abstract

The invention provides a protection system for highway engineering, which comprises a shell open to one side of the road, and a plurality of support rods are installed on the lower end of the shell; The protection mechanism includes four hydraulic cylinders installed horizontally on the inner wall of the housing and arranged in a matrix. One end of the hydraulic cylinder is connected to the first liquid cavity, and the other end of the hydraulic cylinder is vertically connected to the inner cavity side wall of the housing; A third piston is slidably installed on the side close to the first liquid chamber in the inner cavity of the hydraulic cylinder, and the other end of the third piston is connected with a third slider, and the other end of the third slider is installed with straight teeth extending horizontally. The other end of the spur rack runs through the outer wall of the housing on the side away from the rubber membrane and then extends to the outer cavity of the housing. A section of the spur rack located in the inner cavity of the hydraulic cylinder is provided with a third damping spring. The invention is especially suitable for road protection of highway engineering, and has high social use value and application prospect.

Description

Technical field [0001] The present invention relates to the technical field of highway engineering, specifically to a highway engineering protection system. Background [0002] With the continuous development of China's social economy, the number of highways is also increasing, some places of highway engineering protection still has certain defects, such as safety protection on the highway and safety protection at the sharp bend of the highway, etc., although the existing highway is provided with a protective fence or protective device, but the current protective fence or protective device has poor stability, low structural strength, can not effectively prevent the loss of control of the vehicle kinetic energy and potential energy buffer, once the impact will make the vehicle damaged, Casualties can also occur among those inside the vehicle. [0003] The patent no. CN206015574U discloses a highway safety protection net, which includes a plurality of columns, a protective net fix...
