Description

Technical Field

[0001] The utility model relates to the field of guardrails, and more specifically to a self-adaptive regulating device for highway guardrails. Background Art

[0002] Guardrails use the deformation of soil foundations, columns, beams, and polycarbonate panels to absorb collision energy and force out-of-control vehicles to change direction and return to their normal driving direction, preventing them from running off the road, thereby protecting vehicles and passengers and reducing losses caused by accidents.

[0003] For example, the announcement number CN209652754U discloses an automatic adjustment device for bridge guardrail based on the Internet of Things, including a base, a first hydraulic cylinder, a driving motor and a second hydraulic cylinder. A connecting rod is arranged above the base, and a first railing is arranged above the connecting rod, and a second railing is arranged above the first railing. The first hydraulic cylinder is arranged at the lower part of the interior of the base, and a fixed plate is arranged behind the first hydraulic cylinder. A first hydraulic rod is arranged above the first hydraulic cylinder, and a movable plate is arranged above the first hydraulic rod. A fixed rod is arranged above the movable plate, and the fixed rod passes through the surface of the base, the connecting rod and the first railing. The automatic adjustment device for bridge guardrail based on the Internet of Things is provided with a first hydraulic cylinder and a fixed rod. The first hydraulic cylinder can drive the first hydraulic rod, the movable plate and the fixed rod to rise and fall. The fixed rod can drive the second railing to rise and fall during the process of rising and falling, so as to adjust the protective height of the guardrail.

[0004] It can be seen from the above-mentioned public scheme that the current installation of guardrail panels is mostly fixed, and it is not easy to adjust the stretching and contraction of the guardrail panels according to the use requirements, and the automatic extension and contraction effect cannot be achieved, which brings a lot of inconvenience to the use. Moreover, the existing guardrail panels are mostly installed by fixing the lower end of the guardrail panels with bolts to fix them to the ground, but this can easily damage the lower end of the guardrail panels.
