Description

Technical Field

[0001] The utility model relates to the technical field of warning guardrails for engineering construction, in particular to a warning guardrail for highway and bridge engineering construction. Background Art

[0002] When highway construction is carried out, in order to remind and protect the safety of passing pedestrians and vehicles, it is necessary to erect warning guardrails to achieve the effect of isolation and warning. There are various types of structures of warning guardrails, but there is generally a problem of inconvenient assembly. For example, for the front and rear warning guardrails in the actual scenario, bolts are usually required for connection and fixation. In this way, when the staff set them up by the roadside, it will take a lot of installation time. In view of this, a warning guardrail for highway and bridge engineering construction is proposed. Content of the Utility Model

[0003] To solve the technical problem of the assembly of the warning guardrail, the utility model provides a warning guardrail for highway and bridge engineering construction.

[0004] The utility model is realized by the following technical solutions: A warning guardrail for highway and bridge engineering construction, including a frame. On one side of the frame, a plurality of pairs of fixing plates are fixedly connected. Each pair of fixing plates is arranged side by side. Each pair of fixing plates is provided with a clamping mouth. A caliper is rotatably connected between each pair of fixing plates. One side of the caliper close to the clamping mouth is an arc structure. On the side of the frame far from the fixing plates, an assembly matching mechanism is arranged.

[0005] As a further improvement of the above solution, the assembly matching mechanism includes a plurality of pairs of docking plates fixedly connected to the side of the frame far from the fixing plates. Cross bars are fixedly connected between the plurality of pairs of docking plates. Each cross bar and each caliper are paired and arranged respectively.

[0006] As a further improvement of the above solution, a pull rod is fixedly connected to the upper side of each caliper respectively. Counterweights are fixedly connected to both ends of each pull rod respectively.

[0007] As a further improvement of the above solution, a plurality of legs are fixedly connected to the lower side of the frame. Each leg is used for fixedly connecting the warning guardrail to the ground.

[0008] As a further improvement of the above solution, a plurality of support rods are fixedly connected to the inner side of the frame. The plurality of support rods are linearly arranged in an array along the inner side of the frame.

[0009] As a further improvement of the above solution, a cross plate is fixedly connected to the plurality of support rods together. A groove is formed in the cross plate. A plurality of threaded connection holes are formed in the bottom side of the groove. The groove is used for placing warning materials.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. In the utility model, the caliper and the cross bar cooperate with each other. Since the back of the caliper is of an arc structure, when the cross bar on another frame is squeezed into the caliper from the caliper mouth, the caliper is pushed up and opened due to the characteristics of its own structure. When the cross bar smoothly enters the bottom of the caliper mouth, the caliper falls again under the action of its own gravity, achieving the effect of clamping the cross bar. Multiple warning guardrails have the function of quick assembly;

[0012] 2. In the utility model, a pull rod is arranged on the caliper, and counterweights are arranged at both ends of the pull rod. In the case of no external interference, the caliper can safely and reliably clamp the cross bar. When it is necessary to open or disassemble, just pull up the pull rod, which can facilitate the staff to disassemble the warning guardrail group. Description of the Drawings

[0018] Next, in combination with the drawings and specific embodiments, the utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0019] Embodiment:

[0020] Please combine Figures 1-3 In this embodiment, a warning guardrail for highway and bridge engineering construction includes a frame 1. One side of the frame 1 is fixedly connected with multiple pairs of fixed plates 10. Each pair of fixed plates 10 is arranged side by side. A caliper mouth 11 is formed on each pair of fixed plates 10. A caliper 9 is rotatably connected between each pair of fixed plates 10. The side of the caliper 9 close to the caliper mouth 11 is of an arc structure. A fitting and pairing mechanism is arranged on the side of the frame 1 away from the fixed plate 10.

[0021] It should be particularly noted about the structure of the caliper 9. Please combineFigure 3 As shown, the outer side of the caliper 9 is an arc-shaped downward structure, while the inner side is an eagle beak design, which facilitates the smooth rotation when the cross bar 4 jacks up the caliper 9 and tightly locks when it falls, having the characteristics of convenient installation and firm fixation.

[0022] Please refer to Figure 1 As shown, the assembling and pairing mechanism includes 2 pairs of docking plates 3 fixedly connected to the side of the frame 1 away from the fixing plate 10. A cross bar 4 is fixedly connected between the 2 pairs of docking plates 3. Each cross bar 4 and each caliper 9 are paired respectively. It should be noted that the cross bar 4 and the caliper 9 are paired in terms of size.

[0023] Please refer to Figure 3 As shown, a pull rod 8 is fixedly connected to the upper side of each caliper 9, and counterweight blocks are fixedly connected to both ends of each pull rod 8.

[0024] Please refer to Figure 1 As shown, 2 legs 2 are fixedly connected to the lower side of the frame 1. Each leg 2 is used to fixedly connect the warning guardrail to the ground. Bolts are provided at the bottom of the leg 1 for easy fixation to the ground.

[0025] Please refer to Figure 1 As shown, a plurality of support rods 5 are fixedly connected to the inner side of the frame 1, and the plurality of support rods 5 are linearly arranged in an array along the inner side of the frame 1.

[0026] Please refer to Figure 1 As shown, a cross plate 7 is fixedly connected to the plurality of support rods 5 together. A groove 6 is formed in the cross plate 7, and a plurality of threaded connection holes are formed in the bottom side of the groove 6. The groove 6 is used to place warning materials.

[0027] In the embodiment of the present application, the implementation principle of a warning guardrail for highway and bridge engineering construction is as follows: Taking the assembly work of 2 warning guardrails as an example for deduction, move the previous warning guardrail closer to the next warning guardrail so that the cross bar 4 enters through the chuck 11. At this time, the cross bar 4 will first reach the outer surface of the caliper mouth of the caliper 9. Since the caliper 9 is designed with an arc-shaped downward structure, under the pushing action of the cross bar 4, the caliper 9 rotates upward. At this time, the cross bar 4 can smoothly reach the bottom of the chuck 11. And at this time, the caliper 9 falls under the action of the counterweight block of the upper pull rod 8 and its own gravity, and can lock the cross bar 4 entering the bottom, thus achieving the effect of automatic assembly. Reflective films or reflective paints can be used in the groove 6 of the cross plate 7 to set warning materials to warn passers-by, so as to achieve the effect of warning and isolation.

[0028] The above implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the protection scope required by the present invention.
