Description
Technical Field
[0001] The utility model belongs to the field of highway maintenance operations, and particularly relates to a device for fixing a single-column traffic sign on a concrete anti-collision guardrail during highway maintenance. Background Art
[0002] Highways carry a large amount of traffic. To ensure driving safety and smooth roads, it is necessary to regularly inspect and maintain the road surface, bridges, and traffic safety facilities. The biggest construction difficulty lies in the working environment and personnel safety issues. During maintenance operations, the operation control area must be arranged in strict accordance with the construction specifications. Traffic signs can play a role in traffic management such as slowing down and speed limiting. For some special maintenance sections with relatively high bridges and tunnels such as ramps, bridges, and viaducts, the layout of the operation control area is restricted by the roadside concrete anti-collision guardrails. It is not easy for maintenance workers to fix the single-column traffic signs when arranging them. The deflection is large, which is easy to occupy the driving lane, affecting driving safety, and the layout efficiency is low. . Summary of the invention
[0003] The utility model provides a device for fixing a single-column traffic sign on a concrete anti-collision guardrail during highway maintenance in order to solve the technical problem.
[0004] The utility model is implemented by adopting the following technical scheme: a device for fixing a single-column traffic sign to a concrete anti-collision guardrail during highway maintenance, characterized in that: it includes a limiting groove, a support rod is arranged on one side of the limiting groove, and a fixing nut is arranged on the other side, and the fixing nut is connected to the fixing rod through a thread; the support rod and the fixing rod are both hinged with a limiting plate, and the support rod and the fixing rod are connected to the limiting plate through a hinge interface; the limiting groove is also provided with a connecting sleeve, and a tension screw is arranged in the connecting sleeve.
[0005] Furthermore, the limiting groove is an inverted U-shaped frame.
[0006] Furthermore, one end of the support rod is fixed on the limiting groove, and the other end is arranged in an arc shape, and can form a universal rotating structure with the hinge interface.
[0007] Furthermore, the fixing rod is a "T"-shaped structure, and the end thereof is an arc-shaped arrangement, which can form a universal rotating structure with the hinge interface.
[0008] Furthermore, an "H"-shaped steel plate is fixed on the limiting groove.

[0016] The following examples further illustrate the present invention, but are not intended to limit the present invention. Specific experimental conditions and methods not specified in the following examples are conventional methods known to those skilled in the art.
[0017] like Figure 1-Figure 4 , a device for fixing a single-column traffic sign to a concrete anti-collision guardrail during highway maintenance, characterized in that it includes a limiting groove 6, the limiting groove 6 is an inverted U-shaped frame, a rectangular solid steel plate is welded on the top, welded to the connecting sleeve 7, and "H"-shaped steel plates are welded on both sides, four holes are drilled on the left side of the limiting groove 6 for welding a fixing nut 4, and four support rods 3 are welded at corresponding positions on the right side of the limiting groove 6 to achieve the effect of limiting displacement. During on-site construction, the size design can be carried out according to concrete anti-collision guardrails of different structures.
[0018] The fixing nut 4 is connected with a fixing rod 5 by a thread, one end of the fixing rod 5 is outside the limiting groove 6, and is arranged in a "T" shape; the other end is arranged in an arc shape inside the limiting groove 6, and the support rod 3 and the fixing rod 5 are both hinged to the limiting plate 1, preferably, the limiting plate 1 is square, and the support rod 3 and the fixing rod 5 are connected to the limiting plate 1 through a hinge interface 2; the end of the fixing rod 5 arranged in an arc shape is engaged with the hinge interface 2, and the two form a universal rotating structure; the support rod 3 is arranged on the inner side of the limiting groove 6, one end of the support rod 3 is fixed on the limiting groove 6, and the other end is also arranged in an arc shape, and is also engaged with the hinge interface 2, and the two form a universal rotating structure. The limiting plate 1 is attached to the concrete anti-collision guardrail as the main fixing component, the support rod 3 is welded with the limiting groove 6, and as the main supporting component, the fixing rod can adjust the position of the limiting plate through the fixing nut to meet the requirements of the size of the concrete anti-collision guardrail with different structures, and also plays a role in matching and fixing.
[0019] The limiting groove 6 is also provided with a connecting sleeve 7, and a tension screw 8 is provided in the connecting sleeve 7. The connecting sleeve is connected to the limiting groove 6 in the form of a single steel pipe rigid connection, wherein the inner diameter of the connecting sleeve is 2 mm larger than the outer diameter of the traffic sign column, which facilitates the insertion of the column into the sleeve while maintaining the stability of the column, and a hole is opened at a certain height position before and after the connecting sleeve for installing the tension screw 8, and the tension screw passes through the traffic sign column to prevent the column from rotating and becoming unstable.
[0020] The implementation process of the utility model is as follows: according to the concrete anti-collision guardrails of different structures on site, the limiting groove is designed, and then a hole is made for welding the fixing nut. The fixing rod is a "T"-shaped rigid member, and the threading is performed within a certain range in the middle part. The main function is to adjust the position of the limiting plate through the thread to adapt to concrete anti-collision guardrails of different sizes. The limiting groove can be effectively fixed in conjunction with the support rod. The limiting plate is a square steel plate with a central welded hinge. The ends of the fixing rod and the support rod are arc-shaped, and they are interlocked with the hinge to achieve sliding at different angles, so that the limiting plate can fit the concrete anti-collision guardrails of different inclination angles at will. The connecting sleeve is welded at the center position of the top of the limiting groove, wherein the inner diameter of the sleeve is 2mm larger than the outer diameter of the traffic sign column, which facilitates the insertion of the column into the sleeve while maintaining the stability of the column, and a hole is drilled at a certain height position of the sleeve for installing the tension screw, which passes through the traffic sign column to prevent the column from rotating and becoming unstable.
[0021] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or simple replacements that are not conceived through creative work should be included in the protection scope of the present invention.
