Embodiment Construction
[0023] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings. Coordinates X and Y in the figure represent the front-rear direction and the up-down direction, respectively.
[0024] refer to Figure 1-3 As shown, the present invention provides a convenient highway protection device with good cushioning performance, which includes several guardrails, each guardrail includes a bottom plate 1, a buffer air bag 2 and a screw 3, and the buffer air bag 2 is located on the bottom plate At the rear end of 1, several guardrails are stacked one by one along the front and rear direction, and the rear end of the base plate 1 relative to the preceding guardrail is stacked on the front end of the base plate 1 of the guardrail opposite to the rear, and two adjacent guardrails The base plates 1 are superimposed and co...

The invention provides an expressway convenient type protection device with a perfect buffering performance. The expressway convenient type protection device with the perfect buffering performance comprises a plurality of protective fences; each protective fence comprises a bottom plate, a buffering airbag and a bolt; the buffering airbag is arranged at the rear end of the bottom plate; the plurality of protective fences are gradually overlapped in the front-and-back direction direction; the rear ends of the bottom plates of the relatively front protective fences are overlapped at the front ends of the bottom plates of the relatively rear protective fences; and the bottom plates of the two adjacent protective fences are connected with each other through the bolts in an overlapped manner. According to the expressway convenient type protection device with the perfect buffering performance; the impact energy can be absorbed through the deformation of the buffering airbag first; and then the resistances on the bottom plates are overcome by using the bolts in the process of pushing the protective fences to further consume impact forces; and therefore, double consumption has an excellentbuffering effect. Meanwhile, the buffering airbag is in direct contact with a vehicle, more flexible collision is formed to reduce high-speed splashing fragments. Moreover, according to the expressway convenient type protection device with the perfect buffering performance, the number of the protective fences can be selected according to collision energy generated during collisions of different vehicle models at different vehicle speeds so as to guarantee that collisions under multiple situations can be buffered; and therefore, the adaptation is stronger.
Description
[0001] This application is based on the application number 201810295387.6, the application date is March 30, 2018, and the subject name is "One A divisional application filed for a convenient protective device for highways. technical field [0002] The invention belongs to the field of expressway anti-collision devices, in particular to a convenient expressway protection device with good cushioning performance. Background technique [0003] Nowadays, in the process of construction of transportation facilities, the requirements for traffic safety protection facilities are becoming more and more stringent, and their applications are becoming more and more extensive. Among them, anti-collision barriers are the most widely used safety protection facilities. Most of the current anti-collision guardrails are made of concrete, steel plates, steel bars and other materials. They are generally single-layer structures with poor cushioning performance. The quality of the product caus...
