Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision guardrails, in particular to an anti-collision guardrail with a buffering function. Background Art

[0002] Highway guardrails are guardrails placed in the middle of the road or on both sides of the road. They have the function of guiding traffic and reducing the accident rate. They can also stop vehicles when an accident occurs, which can further reduce the safety risks caused by the accident.

[0003] For example, the public document with application number 202210634351.2 discloses a guardrail with anti-collision and buffering functions. The utility model produces a certain buffering and deflection effect on the car through the guiding mechanism and the buffering mechanism. The fixing mechanism reduces the engineering workload of replacing the guardrail, reduces the maintenance cycle, reduces the difficulty and tediousness of replacing the guardrail, and the connecting and installing mechanism ensures the protective effectiveness of the guardrail. However, the anti-collision guardrail protects against car collisions through a single spring and a buffer rope. Although it can provide a certain buffering capacity, the spring is compressed and deformed due to force, resulting in poor buffering. The entire guardrail will still be subjected to a large number of collision impacts, resulting in damage to the guardrail. The overall collision buffering is weak, resulting in poor safety protection.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an anti-collision guardrail with a buffering function is proposed. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model is provided with a damping spring rod, a guard plate, a cross frame, a through cavity, a guide rod, a slider, a telescopic spring and a movable rod. When a collision occurs, the collision object contacts the guard plate first. When the collision impacts, the guard plate moves backward and squeezes the damping spring rod. The damping spring rod can effectively buffer and weaken the collision by utilizing the characteristics of the damper. When the guard plate moves backward, the slider is pushed obliquely to move to both sides along the guide rod through the movable rod, squeezing the telescopic spring. The elastic potential energy of the telescopic spring is utilized to counter the impact force, which can further buffer the collision impact and perform double buffering on the impact, so that the guardrail plays a more effective safety role and can effectively prevent vehicle impact and cause greater damage.

[0015] 2.

By turning the bolt, the moving block is moved downward, and the distance between the first adjusting rod and the second adjusting rod is reduced, so that the connecting ends of the first adjusting rod and the second adjusting rod push the push plate to extend to both sides of the inserting tube, and push the side cone feet to be inserted into the underground soil layer on both sides. The side cone feet are inserted into a T-shaped manner with the inserting cone, which greatly improves the overall installation stability and firmness of the guardrail. At the same time, the extended push plate and the installation ear form a sandwich layer with the soil, so that the guardrail will not tilt or shake as a whole, and further improve the stability of the guardrail installation, effectively preventing the guardrail from tipping over due to vehicle collision and being unable to intercept the vehicle, and greatly improving the interception ability and protective safety performance of the guardrail;

[0016] 3. The utility model provides sound receiving holes and sound absorbing cotton, and the guardrail is assembled on both sides of the road. The noise generated by cars on the road will be absorbed and weakened by the sound receiving holes and sound absorbing cotton, thereby reducing noise pollution in the city.

[0024] Furthermore, the guardrail frame 1 is made of stainless steel, which makes the guardrail frame 1 more corrosion-resistant and has a longer service life.

[0025] Furthermore, the protection plate 3 is arranged on the front side of the guardrail frame 1 to contact with the collision object first, thereby preventing the collision object from directly hitting the guardrail frame 1 and causing deformation and damage to the guardrail frame 1.

[0026] Furthermore, the damping spring rod 2 utilizes its own damper characteristics and is subjected to the collision and compression of the protective plate 3 to significantly buffer the collision impact.

[0027] Furthermore, the movable rod 9 is arranged obliquely. When the protective plate 3 moves, the oblique driving force is used to move the slider 7 to squeeze the telescopic spring 8. The elastic potential energy of the telescopic spring 8 itself can also counter-buffer the collision impact, thereby playing a double buffering role as a whole, making the guardrail more effective in safety.

[0028] like Figure 1 , Figure 2 and Figure 4As shown, support feet 10 are fixedly installed at both ends below the surface of the guardrail frame 1, and mounting ears 11 are fixedly installed on the front and rear sides below the surface of the support feet 10, and the inner wall of the mounting ear 11 is provided with a fixing mechanism 12, the fixing mechanism 12 is composed of an insert cylinder 1201, a bolt 1202, a moving block 1203, a first adjusting rod 1204, a push plate 1205, a second adjusting rod 1206, a side cone foot 1207 and an insert cone 1208, and the inner wall of the mounting ear 11 is penetrated and fixedly installed with an insert cylinder 1201, a bolt 1202 is rotatably provided at the middle part of the bottom end of the inner surface of the insert cylinder 1201 through a bearing, the top end of the bolt 1202 penetrates the insert cylinder 1201, and the surface of the bolt 1202 is threadedly connected with a moving block 1203, and the left and right sides of the surface of the moving block 1203 are rotatably provided with the second screw thread. An adjusting rod 1204, a push plate 1205 is rotatably provided at the lower end of the first adjusting rod 1204 through a rotating shaft seat, and a second adjusting rod 1206 is rotatably provided on one side of the surface of the push plate 1205 through a rotating shaft seat connected to the first adjusting rod 1204, and the bottom end of the second adjusting rod 1206 is rotatably connected to the bottom end of the inner surface of the insert tube 1201 through the rotating shaft seat, a side cone foot 1207 is fixedly installed on the outer side of the surface of the push plate 1205, and an insert cone 1208 is fixedly installed on the bottom end of the outer surface of the insert tube 1201, a sound receiving hole 13 is opened on the surface of the protective plate 3, and a sound absorbing cotton 14 is fixedly installed on the inner surface of the protective plate 3, and a reinforcing plate 15 is fixedly installed on the upper and lower sides of the inner body of the outer surface of the guardrail frame 1, and a sound receiving hole 13 is also opened on the surface of the reinforcing plate 15, and a sound absorbing cotton 14 is also fixedly provided on the inner surface.

[0029] Furthermore, the insert tube 1201 is inserted into the ground through the insert cone 1208, so that the guardrail can be installed stably in an upright position as a whole, and the guardrail frame 1 can be preliminarily installed as a whole.

[0030] Furthermore, the connecting ends of the first adjusting rod 1204 and the second adjusting rod 1206 will gradually extend outward as the moving block 1203 moves downward, pushing the push plate 1205, thereby inserting the side cone feet 1207 into the underground soil layers on both sides. The side cone feet 1207 have insert cones 1208 to form a T-shaped insertion, which greatly improves the overall installation stability and firmness of the guardrail.

[0031] Furthermore, the extended push plate 1205 and the mounting ear 11 form a sandwich layer with the soil, so that the guardrail as a whole will not tilt or shake.

[0032] Furthermore, the sound receiving holes 13 and the sound absorbing cotton 14 absorb and weaken the sound, thereby reducing noise pollution in the city.

[0033] Working principle: When using the anti-collision guardrail with buffering function, first, insert the guardrail frame 1 as a whole into the ground through the insert cone 1208, so that the guardrail can be installed stably as a whole, and then move the moving block 1203 downward by rotating the bolt 1202, and reduce the distance between the first adjusting rod 1204 and the second adjusting rod 1206, so that the connecting ends of the first adjusting rod 1204 and the second adjusting rod 1206 will push the push plate 1205 to extend to both sides of the insert tube 1201, and push the side cone feet 1207 to insert into the underground soil layer on both sides. The side cone feet 1207 are inserted into the T-shaped by the insert cone 1208, which greatly improves the overall installation stability and firmness of the guardrail. At the same time, the extended push plate 1205 and the installation ear 11 utilize the soil shape to The interlayer is formed so that the guardrail as a whole will not tilt or shake. After installation, the noise generated when a car is driving on the road will be absorbed and weakened through the sound receiving holes 13 and the sound-absorbing cotton 14. When the guardrail as a whole is subjected to a collision, the colliding object will preferentially contact the protective plate 3. When the collision impacts, the protective plate 3 moves backward, squeezing the damping spring rod 2. The damping spring rod 2 utilizes the characteristics of the damper to effectively buffer and weaken the collision. Through the movable rod 9, when the protective plate 3 moves backward, the slider 7 will be pushed obliquely along the guide rod 6 to move to both sides, squeezing the telescopic spring 8, and using the elastic potential energy of the telescopic spring 8 itself to counter the impact force, which can further buffer the collision impact and perform double buffering on the impact. This is the working principle of the anti-collision guardrail with buffering function.
