Description

Technical Field

[0001] The utility model relates to the technical field of highway bridges, and in particular to an anti-collision telescopic device. Background Art

[0002] Highway anti-collision devices are a relatively common traffic equipment, especially on highways. However, the existing anti-collision devices are relatively simple in design, and all use some simple corrosion-resistant and high-strength materials for structural design. In the event of an accident, once a strong collision occurs between the car and the device, the degree of damage to the car will be relatively high, and the device itself will also suffer greater damage, causing greater social losses.

[0003] The existing device only installs an anti-collision device on the bridge. Its structure is simple and it only uses spring connection for buffering. However, the buffering effect of this anti-collision device is not ideal. When the vehicle collides, it will cause a huge impact force, which will bring safety hazards to the people in the vehicle and the buffering effect is poor. Therefore, we propose an anti-collision telescopic device. Utility Model Content

[0018] Usage process:

[0019] During use, when the guardrail is hit and needs to be buffered, the protective pad 11 and the buffer plate 10 are hit, the buffer spring 12 shrinks and deforms, and at the same time the connecting plate 8 moves backward after being hit, thereby squeezing the movable rod 6, the angle between the two movable rods 6 becomes larger, and the two sleeves 5 move outward. At the same time, the spring 13 is squeezed and contracted, absorbing external force for buffering, so that it absorbs the lateral impact of the out-of-control vehicle, and can effectively absorb the longitudinal impact of the high-speed out-of-control vehicle, thereby preventing the out-of-control vehicle from having excessive kinetic energy and causing injuries to most people in the car and damage to highway bridges.

[0020] In the above process, through the arrangement of the sleeve, movable rod, support plate, connecting plate, connecting rod, buffer plate, protective pad, buffer spring, spring one and spring two, the protective pad and buffer plate are hit, the buffer spring shrinks and deforms, and at the same time the connecting plate moves backward after being hit to squeeze the movable rod, the angle between the two movable rods becomes larger, and the two sleeves move outward. At the same time, spring one is squeezed and contracted, absorbing external force for buffering, so that it absorbs the lateral impact of the out-of-control vehicle, and can effectively absorb the longitudinal impact of the high-speed out-of-control vehicle, thereby achieving the effect of preventing the out-of-control vehicle from having excessive kinetic energy and causing injuries to most people in the vehicle and damage to highway bridges; through the arrangement of T-blocks, T-slots and screw holes, a new buffer plate can be replaced after the buffer plate is damaged and cannot be used, thereby saving costs; the present application has a simple structure, strong practicality, and simple operation, and is worthy of promotion.
