Description
Technical Field
The invention belongs to the technical field of continuous guardrails extending along roads or positioned between lanes, and particularly relates to a method and a system for continuously forming and preparing an anti-blocking block.
Background
The wave-shaped beam guardrail absorbs collision energy by utilizing the deformation of the soil foundation, the upright posts and the wave-shaped cross beams, forces the out-of-control vehicle to change the direction and return to the normal running direction, prevents the vehicle from rushing out of the road, protects the vehicle and passengers and reduces the loss caused by vehicle accidents.
The anti-blocking block is a force bearing part between the wave-shaped beam and the upright post. On one hand, the vehicle impact energy is absorbed through self deformation, and the collision resistance and the energy absorption function of the corrugated beam guardrail are enhanced; on the other hand, the wave-shaped beam and the upright post are separated by the anti-blocking block by a certain distance, so that the collision vehicle and the upright post are prevented from being mixed and blocked, and the adverse effect of the curb on the motion track of the collision vehicle is reduced; moreover, prevent that the piece is fixed between stand and wave form roof beam, participate in guardrail whole effect back, can make the impact distribute more stride the structure to increase the bulk strength of guardrail. Therefore, the anti-blocking block plays a very important role in the corrugated girder guard rail.
The upright columns of the corrugated beam guardrail are divided into steel pipe upright columns, square pipe upright columns and H-shaped steel upright columns. When the steel pipe upright post is connected with the corrugated beam plate, a steel pipe upright post anti-blocking block matched with the steel pipe upright post anti-blocking block is adopted, and the anti-blocking block is hereinafter referred to as an anti-blocking block.
The structure of the anti-blocking block is as follows, part 2 of the corrugated beam steel guardrail of the national standard of the people's republic of China (GB/T31439.2-2015): the cross-sectional structure of the three-wave beam steel guardrail "section 4.2.5, fig. 10, is a hexagon with one concave side.
At present, the common method for manufacturing the steel pipe upright post anti-block is as follows: 1. cutting the steel plate according to the size requirement of a single anti-blocking block; 2. rolling the steel plate into a cylinder shape; 3. manually welding the cylinder to obtain a circular steel pipe section; a part of the steel pipe is a finished steel pipe, and the steel pipe is cut into a circular steel pipe section according to the size requirement of a single anti-blocking block; 4. and shaping the round steel pipe section into a hexagonal pipe section with one side concave inwards, and performing anticorrosive treatment on the single hexagonal pipe section, such as galvanizing, plastic spraying or antirust paint coating, to obtain a single anti-blocking block.
The circular pipe section is obtained by cutting, coiling and welding the steel plate, the circular pipe section is shaped into a hexagonal pipe section, and the whole process of anti-corrosion treatment is mutually separated and discontinuous, so that the efficiency is extremely low; the steps of mutual separation make the geometric consistency of the product difficult to guarantee; a large amount of blanking loss exists when the steel plate is cut according to the size requirement of a single anti-blocking block.
In the method of cutting the finished steel pipe into circular pipe sections, the two ends of the finished steel pipe are deformed during transportation, so that the two ends of the circular pipe sections cannot be used, and a large amount of material is lost. Similarly, the processes of shaping the circular pipe section into the hexagonal pipe section and performing the anti-corrosion treatment are separated and discontinuous, and the efficiency is still extremely low.
