Description

Technical Field

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

[0002] Traffic guardrails have been widely used on urban roads. They can prevent vehicles from running off the road and causing traffic accidents. At the same time, they separate the opposite lanes to prevent head-on collisions with oncoming vehicles. They can also prevent vehicles from hitting pedestrians. They play an important role on modern roads. In this regard, how to maintain traffic guardrails, reduce damage to traffic guardrails, and further reduce the occurrence of traffic accidents has become a major issue.

[0003] For example, a traffic guardrail with a protective function disclosed in patent authorization number CN207228005U includes a guardrail body, a fixed block, a cross bar, a vertical bar, a connecting block, a support seat, a slide groove, a movable rod, a buffer plate, a buffer pad, an extrusion plate, a slider, a vertical plate, a movable rod, a buffer shell, a skateboard, and a buffer spring. When a vehicle loses control and hits the guardrail, it will first touch and squeeze the buffer pad. The movable rod then drives the skateboard to move on the slider toward the inside of the guardrail body, so that the buffer spring is squeezed. The elasticity of the spring is used to exert a buffering effect, thereby providing certain protection for the traffic guardrail.

[0004] However, this device can only cope with smaller-scale collisions. When the impact force of a vehicle losing control is large, the lateral stress on the cross-section of the root of the railings on both sides of the guardrail is too great, and it is unable to further relieve pressure, which will directly cause the railings on both sides to bend or even break, and the buffering effect of the guardrail will fail. At the same time, it cannot avoid the occurrence of traffic accidents.

[0005] For this purpose, we provide a traffic guardrail with an anti-collision structure. Utility Model Content

[0006] In order to solve the problem of how to further relieve pressure at the bottom of the railings on both sides of the guardrail, the purpose of the utility model is to provide a traffic guardrail with an anti-collision structure.

[0007] The utility model provides a traffic guardrail with an anti-collision structure, comprising a fixing box, a pressure relief mechanism is arranged on one side of the fixing box, a fixing plate is fixed on the bottom of the pressure relief mechanism, the fixing plate is fixedly connected to the fixing box by bolts, a pushing block is fixedly connected to the surface of the pressure relief mechanism, a sliding block is fixedly connected to the lower surface of the pushing block, a sliding rail is slidably connected to the surface of the sliding block, a bottom fixing block is fixedly connected to the surface of the sliding rail, the bottom fixing block is fixedly connected to the surface of the fixing box, a rail is fixedly connected to the upper surface of the pushing block, a guardrail is fixedly connected to one side of the railing, a hole is provided on the surface of the guardrail, a bottom plate is fixedly connected to the surface of the guardrail, a spring is fixedly connected to the top of the spring, a second connecting block is fixedly connected to the middle surface of the bottom plate, a telescopic rod is fixedly connected to the top of the telescopic rod, a clamping block is fixedly connected to the surface of the clamping block, a rotating rod is rotatably connected to the surface of the rotating rod, a first connecting block is sleeved on the surface of the rotating rod, and a cushion is fixedly connected to the surface of the first connecting block.

[0008] Preferably, the fixed box includes a box body, a button is provided on the inner wall surface of the box body, a signal receiver is provided below the button, the signal receiver is fixed to the inner wall of the box body, a signal transmitter is fixedly connected to the surface of the signal receiver, an antenna is fixedly connected to the upper surface of the signal receiver, and the number of the antennas is two, a metal stopper is fixed to one side of the box body, a cover plate is fixedly connected to the surface of the box body, and the cover plates are symmetrically distributed on both sides of the box body with the box body as the center.

[0009] Preferably, the pressure relief mechanism includes a push plate, the lower surface of the push plate is fixedly connected to a sliding cavity, the top of the inner wall of the sliding cavity is fixedly connected to a thick spring, the bottom of the thick spring is fixedly connected to a limiting block, the surface of the sliding cavity is slidably sleeved with a stabilizing cavity, the inner wall of the stabilizing cavity is slidably connected with a metal sliding rod, the metal sliding rod penetrates the surface of the fixed plate and is slidably connected to the fixed plate, the surface of the metal sliding rod is sleeved with a limiting block, the surface of the metal sliding rod penetrates and is opened with a threaded hole, the inside of the metal sliding rod penetrates and is slidably connected with a threaded hole, the limiting structure is slidably connected to the inner wall of the stabilizing cavity, the inner wall of the sliding cavity is fixedly connected with a triangular slider, the triangular slider is slidably connected to the surface of the limiting structure, and the number of the triangular sliders is two.

[0010] Preferably, a group of fixing boxes, a group of pressure relief mechanisms, a group of fixing plates, and a group of bottom fixing blocks are symmetrically arranged on both sides of each railing, and the number of each group is two.

[0011] Preferably, a guardrail is fixedly connected between every two railings, and the number of holes opened on the surface of the guardrail is determined by the length of the guardrail in actual conditions. The number of structures on each base plate and its surface is similarly determined by actual conditions. The second connecting block and a spring are grouped together, and there are two groups on each base plate, and the two groups are symmetrically distributed on the upper surface of the base plate with the telescopic rod as the center.

[0012] Preferably, the bottom of the telescopic part of the telescopic rod passes through the bottom plate, and the maximum elongation is always less than or equal to the thickness of the bottom plate, providing telescopic space for the telescopic rod. The length of the part of the metal sliding rod extending from the lower surface of the fixed plate is always less than or equal to the distance between the metal stopper and the button.

[0014] The technical effects that can be obtained by the technical means of the utility model are:

[0015] (1) The utility model provides a telescopic rod, a clamping block, a rotating rod and a first connecting block, so that the cushion can bear forces generated by different force directions. When the lower half of the cushion is squeezed, the first connecting block will rotate slightly on the surface of the rotating rod, and only the second connecting block and the spring on the lower side of the bottom plate will be subjected to the impact force of compression. Only when the middle part of the cushion is compressed, the telescopic rod will be compressed, and the second connecting blocks and the spring on the upper and lower sides of the bottom plate will be compressed, thereby improving the service life to a certain extent.

[0016] (2) The utility model provides a fixing box so that the device has an alarm function. When the guardrail is hit with great force, the metal slide bar will penetrate the metal block and then touch the button. The signal receiver receives the collision information and feeds it back to the signal transmitter. The signal transmitter sends a signal through the antenna. Relevant personnel will immediately receive the message and come to the scene to carry out maintenance or check whether a traffic accident has occurred.

[0017] (3) The utility model provides a pressure relief mechanism to relieve pressure at the base of the railings on both sides of the guardrail to prevent the railings from bending or breaking. By providing a limiting structure, the two triangular sliders fixedly connected to the surface of the sliding cavity can be driven to slide in the stable cavity. Due to the shape characteristics of the limiting structure, the limiting structure slides inside the metal slide bar, and the surfaces on both sides will touch the edges of the metal slide bar, jamming the metal slide bar and preventing it from sliding. This limits the length of the metal slide bar extending outward from the fixed plate and sliding inward to a certain extent, preventing the metal slide bar from piercing the entire fixed box and causing damage.
