A flexible fence

Abstract

The invention discloses a flexible protecting fence, which comprises a pile pillar (1); the key is that the pile pillar (1) is connected with a connecting device (2); at least three steel cables (3) are fixedly connected with a shearing block (6) and connected with the connecting device (2); the stretching intensity of the steel cables (3) is more than the bending intensity of the connecting device (2), the shearing intensity of the shearing block (6) is less than the bending intensity of the connecting device (2); the bending intensity of the connecting device (2) is less than the bending intensi8ty of the pile pillar (1), a flexible plate (5) with a metal weaving mesh (4) is connected with the steel cable (3). After fully studying various protecting fences in the prior art, the protecting fence with very good comprehensive performance and safety performance is produced.

Description

Technical field: [0001] The present invention relates to a protective device, in particular to a protective barrier for preventing the movement or protection of high-speed objects, and in particular to a flexible protective barrier for preventing high-speed vehicles from rushing out of a set road surface. Background technique: [0002] With the progress and development of society, the increasingly motorized means of transportation, the use of various moving objects such as vehicles or ships is very common, and there are more and more collisions between motor objects and other fixed objects, such as motor vehicle traffic Accidents have increased significantly in recent years, causing a considerable number of casualties, or when a large number of ships of various sizes shelter from the wind during normal navigation or typhoons, a large number of ship-to-ship or ship-to-wharf collision accidents occurred, resulting in Quite a huge property loss and casualties. What needs to be...

AI Technical Summary

Problems solved by technology

Because the isolation anti-collision (protection) device on both sides or in the middle of the existing expressway is to arrange a pile at a distance, a guard plate is set between two adjacent piles, and the guard plate two ends are fixed with the pile, and the guard plate According to the national standard, it is a galvanized steel plate with a thickness of 4mm. This steel plate has considerable strength and elasticity. According to the statistics and analysis of a large number of traffic accidents by the highway management department, when the vehicle is a large or heavy-duty vehicle, the above-mentioned existing protection The device will basically be damaged by impact, but for a large number of small and medium-sized vehicles passing through, such as the vehicle speed is fast and the impact angle is large, the impact of the above-mentioned high-strength steel plate and the vehicle will often cause large deformation of the vehicle and cause casualties. If the impact angle is small, the high elasticity of the steel plate will cause the impacting vehicle to pop up to the other side, causing a secondary collision between the impacting vehicle and the vehicle behind it, resulting in a secondary accident or a series of collisions. This phenomenon occurs in rainy, foggy or Snow and ice are especially common

Therefore, there are obvious defects in the design requirements of the protective plate or protective device of the highway at present. In addition, the above-mentioned galvanized steel sheet will produce a large amount of pollution in the production process, and it will be polluted by air during long-term use. The galvanized protection is difficult to last. easy to corrode

How to reduce the impact intensity of the first impact and reduce the occurrence of the second impact is the key issue in reducing traffic accidents on the expressway. The solution to this problem undoubtedly has very high economic value and social significance (reducing casualties). In fact, in rivers or The above-mentioned problems also exist in the collision between ships along the coast or in the harbor, especially the front ends of the ships are pointed, and it is also prone to ship damage or casualties
