[0023] In order to make the technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0024] The present utility model provides a technical solution: Refer to Figure 1 - Figure 5 , a novel guardrail plate for highway protection disclosed by the present utility model includes a parapet 1 and a support leg 2. The parapet 1 and the support leg 2 are connected by a connecting mechanism 3. The connecting mechanism 3 includes a fixing plate 31, and a warning mechanism 4 is provided on the fixing plate 31;
[0025] One side of the fixing plate 31 is fixedly connected to the support leg 2 by bolts. A chute 32 is opened at the middle position on the other side of the fixing plate 31. A slider 33 is slidably installed in the chute 32, and the slider 33 is fixedly connected to the parapet 1 by bolts. A spring 34 is provided between the slider 33 and the inner wall of the chute 32, and both ends of the spring 34 are fixedly connected to the slider 33 and the inner wall of the chute 32 respectively.
[0026] In this embodiment, when the improved guardrail plate for highway protection is in use, with the temporary contact between the vehicle and the parapet 1, the moving vehicle can exert a thrust on the parapet 1 through the frictional force between the vehicle and the parapet 1. At this time, the slider 33 slides in the chute 32, so that the parapet 1 can be adjusted in position to a certain extent as needed, and finally the vehicle is temporarily attached to the parapet 1, without exerting a pulling force on the support leg 2, thereby avoiding damage to the highway guardrail plate, and avoiding damage to the support leg 2 caused by a large external force on the support leg 2 due to the temporary contact between the vehicle and the highway guardrail plate, and further reducing the maintenance cost of the highway guardrail plate.
[0027] In a further preferred embodiment of the present utility model, as Figure 4 shown, the cross-sectional shape of the slider 33 and the cross-sectional shape of the chute 32 are both set to be T-shaped, and several corners of the slider 33 are set to be arc-shaped;
[0028] In this embodiment, the T-shaped cross-section of the slider 33 and the cross-section of the chute 32 can, after the high-speed guardrail plate is assembled, exert a binding force on the parapet 1 through the mutual contact between the slider 33 and the inner wall of the chute 32, so that the parapet 1 and the fixing plate 31 are stably connected together.
[0029] In a further preferred embodiment of the present utility model, as Figure 2 shown, a plurality of support plates 5 are fixedly installed on the outer peripheral side of the bottom of the support leg 2 in a circumferential array, and each support plate 5 is a triangular plate;
[0030] In this embodiment, the arrangement of the support plates 5 can form a plurality of triangular support structures between the support leg 2 and the ground, thereby enhancing the strength of the bottom of the support leg 2.
[0031] In a further preferred embodiment of the present utility model, as Figure 4 and Figure 5 shown, the warning mechanism 4 includes a whistle 41. The whistle 41 is arranged at the rear side of the fixing plate 31, and the air inlet end of the whistle 41 is inserted into the sliding groove 32 and fixedly connected to the fixing plate 31;
[0032] In this embodiment, during the movement of the slider 33, the gas in the sliding groove 32 can be pushed out from the whistle 41, and the flowing air current in the whistle 41 makes the whistle 41 emit a sharp sound to warn the vehicle driver, without applying an additional driving structure on the highway guardrail plate, reducing the manufacturing cost of the device.
[0033] In a further preferred embodiment of the present utility model, as Figure 4 shown, the spring 34 is in a compressed state, and the spring 34 is in clearance fit with the whistle 41;
[0034] In this embodiment, when the vehicle is separated from the railing 1, due to the pushing of the spring 34 on the slider 33, the slider 33 and the railing 1 are automatically reset, and the compressed state of the spring 34 makes the slider 33 always receive a strong reset thrust.
[0035] In a further preferred embodiment of the present utility model, as Figure 3 and Figure 4 shown, an annular groove 42 is formed on the other side of the fixing plate 31, and the annular groove 42 is sleeved on the outer peripheral side of the sliding groove 32, and a sealing ring 43 is slidably installed in the annular groove 42;
[0036] In this embodiment, after the highway guardrail plate is assembled, with the fitting of the guardrail plate and the fixing plate 31, the sealing ring 43 automatically seals the gap between the fixing plate 31 and the guardrail plate, thereby preventing external rainwater from flowing into the sliding groove 32 to erode the inner wall of the sliding groove 32 and the slider 33 and affecting the use of the device.
[0037] In a further preferred embodiment of the present utility model, as Figure 4 shown, storage grooves 44 are oppositely formed on the inner wall of the open end of the sliding groove 32, sealing strips 45 are installed in the storage grooves 44, and the outer wall of the slider 33 is in contact with the outer peripheral wall of the sealing strip 45;
[0038] In this embodiment, during the process of the slider 33 sliding in the chute 32, the sealing ring 43 and the sealing strip 45 can block the gaps between the fixed plate 31 and the guardrail plate and between the slider 33 and the inner wall of the chute 32. Thus, the slider 33 sliding in the chute 32 can directly push all the gas into the whistle 41, preventing the whistle 41 from failing to make a sound due to too little air flow.
[0039] Working principle: When assembling the improved highway guardrail plate, the operator first fixes the support legs 2 at appropriate positions on both sides of the highway through expansion screws. Subsequently, the fixed plate 31 is fitted onto the mounting surface of the support legs 2, and bolts are used to connect the fixed plate 31 and the support legs 2. Finally, bolts are used to connect the railing plate 1 and the fixed plate 31, completing the assembly of the improved highway guardrail plate.
[0040] When the improved highway guardrail plate is in use, as the vehicle touches the railing plate 1, the moving vehicle can apply a thrust to the railing plate 1 through the friction between the vehicle and the railing plate 1. At this time, the slider 33 slides in the chute 32. Due to the sealing of the gaps between the slider 33 and the inner wall of the chute 32 and the railing plate 1 by the sealing strip 45 and the sealing ring 43, the sliding slider 33 pushes the gas in the chute 32 towards the whistle 41. Thus, the excess gas in the chute 32 is discharged from the whistle 41, and the flowing air in the whistle 41 makes the whistle 41 emit a sharp sound to warn the vehicle driver, reminding the operator to quickly separate the vehicle from the highway guardrail plate. Moreover, due to the movement of the slider 33, the railing plate 1 can be adjusted in position to a certain extent as needed. Finally, the temporary fitting of the vehicle and the railing plate 1 will not exert a pulling force on the support legs 2, thereby preventing damage to the highway guardrail plate.
[0041] When the vehicle separates from the railing plate 1, due to the spring 34 pushing the slider 33, the slider 33 and the railing plate 1 automatically move in the opposite direction and reset.
[0042] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, various changes and improvements will occur to the present invention, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
