Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of highway guardrail equipment, and particularly relates to an installation mechanism for a highway guardrail guiding device. Background Art
[0002] The anti-collision guardrails on the sides of expressways and provincial roads are used to indicate the highway boundary and prevent potential safety hazards caused by people and animals suddenly appearing on the road. In some locations such as cliffs, elevated bridges, and lakes, the anti-collision guardrails can also prevent vehicles from running off the road. The anti-collision guardrails are generally corrugated guardrails, that is, the cross-section is a corrugated structure. When being impacted, the self-deformation can absorb part of the kinetic energy, slow down the vehicle speed, and reduce the risk coefficient of the vehicle.
[0003] Due to the corrugated structure on the surface of the corrugated guardrail, it is very difficult to install guiding signs. On some curved roads, drivers are prone to hitting the guardrail because they fail to notice the curve in time. Therefore, it is very necessary to install warning signs on the guardrail surface. Content of the Utility Model
[0004] The purpose of the utility model is to provide an installation mechanism for a highway guardrail guiding device, so as to solve the problem that the installation of warning signs on the high-speed guardrail is unstable due to its arc-shaped surface.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0006] An installation mechanism for a highway guardrail guiding device includes a sign board installed on a corrugated guardrail. The sign board is a rectangular plate structure, a reflective sticker is fixed on the front of the sign board, and the back of the sign board is fixed to the corrugated guardrail through a mounting bracket.
[0007] The mounting bracket is a multi-segment arc structure. The mounting bracket includes a first arc portion at the central position, and the two sides of the first arc portion are symmetrically arranged upper and lower second arc portions. The central positions of the second arc portions coincide with the corresponding upper and lower arc portions of the corrugated guardrail, and corresponding holes are opened. The sign board is fixed at the corresponding hole positions through a fixing device.
[0008] Furthermore, the fixing device includes a screw installed on the sign board. One end of the screw is installed on the sign board, and the other end extends through the holes of the mounting bracket and the corresponding holes of the corrugated guardrail, and is fixed through a nut.
[0009] The screw is hingedly installed on the sign board. A hinge shaft is fixed at the corresponding hinged end of the screw. The screw is vertically fixed at the center of the hinge shaft. The sign board is fixed with hinge sleeves sleeved at both ends of the hinge shaft, so that the screw is horizontally rotatable.
[0010] The utility model has the following beneficial effects: the raised peak section of the first arc-shaped portion extends to the central trough position corresponding to the corrugated guardrail and forms an interference, and the corresponding second arc-shaped portions on both sides are used to abut and engage with the crest position of the corrugated guardrail to form a support, and at the same time serve as fixed points. There are four fixed points distributed at the four corner positions of the identification plate, which improves stability and facilitates installation.
[0011] The identification plate is fixed by a mounting frame, which increases the overlap surface with the corrugated guardrail, so the installation stability is higher. At the same time, the mounting frame is composed of multiple arc sections, and the corresponding arc sections match the arc structure of the corrugated guardrail cross-section. When the identification plate is impacted, the mounting frame deforms and extends to absorb part of the kinetic energy, thereby reducing the danger of the vehicle after the collision. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 : Schematic diagram of the disassembled structure of the back of the identification plate of the utility model.
[0015] Figure 3 : Schematic diagram of the structure of the installation method of the identification plate of the utility model.
[0016] In the accompanying drawings, the components represented by the various reference numerals are listed as follows: corrugated guardrail 1, identification plate 2, mounting frame 3, first arc-shaped portion 31, second arc-shaped portion 32, screw rod 4, hole 33, nut 41, hinge shaft 42, hinge sleeve 21. DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0018] like Figures 1-3 As shown: a highway guardrail guide device installation mechanism, including a signboard 2 installed on a corrugated guardrail 1, the signboard 2 is a rectangular plate structure, a reflective sticker is fixed on the front of the signboard 2, the reflective sticker is an arrow mark, made of reflective material, used for highlighting, and providing boundary guidance for drivers. The back is fixed to the corrugated guardrail 1 through a mounting frame 3; the cross section of the corrugated guardrail is a corrugated shape, presenting a sine curve.
[0019] The mounting frame 3 is a multi-section arc structure, and the mounting frame 3 includes a first arc portion 31 at the central position, and the two sides of the first arc portion 31 are second arc portions 32 that are symmetrical up and down. The central position of the second arc portion 32 coincides with the upper and lower arc portions corresponding to the corrugated guardrail 1, and a corresponding opening is formed, and the corresponding opening position of the identification plate 2 is fixed by a fixing device. The raised peak section of the first arc portion extends to the central trough position corresponding to the corrugated guardrail and forms a conflict. The corresponding second arc portions on both sides are used to abut and engage with the crest position of the corrugated guardrail to form a support, and at the same time serve as a fixing point. There are four fixing points, which are distributed at the four corner positions of the identification plate to improve stability and facilitate installation.
[0020] The identification plate is fixed by a mounting frame, which increases the overlap surface with the corrugated guardrail, so the installation stability is higher. At the same time, the mounting frame is composed of multiple arc sections, and the corresponding arc sections match the arc structure of the corrugated guardrail cross-section. When the identification plate is impacted, the mounting frame deforms and extends to absorb part of the kinetic energy, thereby reducing the danger of the vehicle after the collision.
[0021] like Figure 2 As shown: the fixing device includes a screw rod 4 installed on the identification plate 2, one end of the screw rod 4 is installed on the identification plate 2, and the other end extends through the mounting frame 3 and the corresponding holes 33 of the corrugated guardrail, and is fixed by a nut 41.
[0022] The screw rod 4 is hingedly mounted with the identification plate 2. A hinge shaft 42 is fixed to the corresponding hinge end of the screw rod 4, the screw rod 4 is vertically fixed to the center of the hinge shaft 42, and the identification plate 2 is fixed with a hinge sleeve 21 sleeved on both ends of the hinge shaft 42, so that the screw rod 4 is turned horizontally.
[0023] Since the sign board is installed at the arc position of the corrugated guardrail, corresponding to the turning position of the highway, the corrugated guardrail presents an arc section, while the sign board is a flat structure and cannot match the arc section of the corrugated guardrail, resulting in the screw rod needing a longer length to fix the sign board. The screw rod can be flipped in the horizontal direction to make up for the distance difference caused by the arc section and improve the installation stability.
[0024] This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can better understand and utilize the present invention.
