Technical Field
[0001] The utility model belongs to the technical field of guardrails, and in particular relates to a self-resetting corrugated guardrail. Background Art
[0002] Guardrails - Here we are talking about industrial "guardrails". Guardrails are mainly used for the protection and protection of personal safety and equipment facilities in residential areas, highways, commercial areas, public places and other places. Among them, corrugated guardrails are often used in expressways to play the role of guardrails. Common facilities for highway collision prevention are the main form of semi-rigid guardrails. It is a continuous structure with corrugated steel guardrail plates spliced together and supported by main columns. Corrugated guardrails are mainly used to prevent out-of-control vehicles from running off the road. They are generally made of galvanized steel plates. Different specifications are used according to different highway grades. It uses the deformation of the foundation, columns, and beams to absorb the collision energy, and forces the out-of-control vehicle to change direction and return to the normal driving direction to prevent the vehicle from running off the road, so as to protect the vehicle and passengers and reduce the losses caused by accidents. It is widely used in national highways, expressways and highways, and the length of the guardrail is generally the same as the length of the road.
[0003] The common corrugated guardrails on the road at present are mainly made of galvanized steel plates, which are generally pressed into corrugated shapes. When in use, they are fixed between multiple columns and the ground, and the galvanized steel plates are installed on the front of the columns to achieve a continuous guardrail. Since these guardrails are mostly set on both sides of the road, when facing a collision with a high-speed vehicle, the traditional corrugated guardrail plates cannot effectively dissipate the force. They are extremely fragile when facing a collision, and the guiding performance causes greater damage to the people inside the vehicle. In addition, the traditional corrugated guardrails along most roads are of a single composition, and lack innovation in the conduction of energy dissipation inside the guardrail.

DETAILED DESCRIPTION
[0024] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.
[0025] like Figures 1 to 6 As shown, a self-resetting corrugated guardrail comprises a column 1, wherein the number of the columns 1 is two, a fixing block 9 is installed at the bottom end of each of the two columns 1, a hydraulic rod 15 is installed at the top and bottom of the front of the column 1, respectively, and the hydraulic rod 15 is connected to the corrugated beam 2 through a circular conical spiral spring 14, a reflective strip 13 is installed in the middle of the front of the corrugated beam 2, and an anti-blocking block 12 is installed in the middle of the back of the corrugated beam 2;
[0026] A slide rail 3 is installed on the side of the column 1, and the slide rail 3 penetrates and connects two columns 1. A connecting rod 8 is connected to the middle of the front of the slide rail 3, and the connecting rod 8 is connected to the transverse mounting seat 4 through screws 7. The transverse mounting seat 4 is connected to an anti-obstruction block 12.
[0027] In this configuration, the slide rail 3 is at the same horizontal position as the middle of the corrugated beam 2 , and both ends of the slide rail 3 are fixed by mounting grooves 10 provided on the column 1 , and the mounting grooves 10 are provided at the top end of the slide rail 3 .
[0028] In this configuration, reset springs 6 are provided on the inner sides of both ends of the slide rail 3, and circular-section cylindrical helical compression springs 5 are provided on the left and right sides of the slide rail 3 respectively. A slider 11 is provided on the end of the circular-section cylindrical helical compression spring 5 opposite to the reset spring 6, and a connecting rod 8 is provided on the circular-section cylindrical helical compression spring 5 away from the end of the slider 11. The connecting rod 8 is movably connected to the mounting seat 4. When the circular-section cylindrical helical compression spring 5 is deformed, the slider 11 slides and squeezes the reset spring 6 to achieve a buffering effect.
[0029] The sliding block 11 is a plastic rubber block with relatively large elasticity, wear resistance and cold resistance.
[0030] In this configuration, the four ends of the back side of the corrugated beam 2 are fixedly connected with circular-section conical helical springs 14 .
[0031] In this configuration, screws 7 are installed at the four corners of the top of the fixing block 9 .
[0032] In this configuration, the middle portion of the front side of the corrugated beam 2 is concave inwards.
[0033] In this configuration, the circular conical helical spring 14 is installed at the four ends of the back of the corrugated beam 2. The implementation principle of a self-resetting corrugated guardrail of this embodiment is as follows:
[0034] When the corrugated guardrail is not hit, the circular cross-section cylindrical helical compression spring 5 and the reset spring 6 in the slide rail 3, as well as the circular cross-section conical helical spring 14 and the hydraulic rod 15 are all in a relaxed state, and the connecting rod 8 forms a certain angle with the transverse mounting seat 4. The reflective strip 13 arranged in the middle of the guardrail corrugated beam 2 uses the reflective effect of the reflective paint to provide a certain warning to oncoming vehicles.
[0035] When the corrugated guardrail is hit, the anti-blocking block 12 in the middle of the back of the corrugated beam 2 and the circular conical coil spring 14 fixedly connected to the four ends of the back of the corrugated beam 2 are first subjected to the impact force, and the circular conical coil spring 14 offsets part of the force, which is the first buffering and force elimination effect; the remaining force propagates backward, and at the same time pushes the hydraulic rod 15, driving the connecting rod 8 connected to the transverse mounting seat 4 to move, triggering the circular cylindrical coil compression spring 5 to buffer to the left and right sides, which is the second buffering and force elimination effect; when the circular cylindrical coil compression spring 5 is deformed, the slider 11 slides and squeezes the reset spring 6 to achieve a buffering effect, which is the third buffering and force elimination effect. The combined action of the components to achieve buffering and force elimination forces the vehicle to change direction, which can reduce the huge impact force of the collision on the vehicle, thereby reducing the physical damage of the people inside the vehicle.
[0036] After the collision occurs, the reset spring piece 6 and the circular cross-section cylindrical helical compression spring 5 themselves recover their deformation by using the energy stored in the collision, and return to the relaxed state.
[0037] It should be noted that the above description is only the best embodiment of the utility model. Inspired by the utility model, various similar expressions made by technicians in this field without violating the scope of protection of the utility model and the claims all fall within the scope of protection of the utility model.
