Description

Technical Field

[0001] The invention relates to the field of iron tower signboard fixing, in particular to an overhead line signboard mounting bracket. Background Art

[0002] In the years of overhead line operation and maintenance, we often find that the safety, health and environmental signs are discolored, rusted, fallen off, and lost, losing their proper warning function, which not only brings inconvenience to defect handling, but also buries the hidden danger of mistakenly climbing the tower during line maintenance. Traditional installation uses bolt fixing or wire binding. Under the action of long-term wind, sun, rain, external force, etc., discoloration and rust occur, causing the sign to fall off and be lost. Because overhead line towers of different voltage levels are of different sizes, different assembly forms, and different sizes of signboards, through research, a universal installation bracket is made that can be applied to various types of towers to solve the problem of signboard falling off and being lost.

[0005] Preferably, the present invention may also have the following technical features:

[0006] A mounting bracket for an overhead line sign comprises an adapter plate and a clamping mechanism, wherein the clamping mechanism comprises two L-shaped plates, namely an outer L-shaped plate and an inner L-shaped plate, wherein the outer L-shaped plate is stacked on the outer side of the inner L-shaped plate; corresponding connecting holes are provided at corresponding positions at both ends of the outer L-shaped plate and the inner L-shaped plate; the outer L-shaped plate and the inner L-shaped plate are detachably connected via the connecting holes; the adapter plate is provided with a positioning hole connected to the connecting hole, and the adapter plate is combined with one end of the outer L-shaped plate and / or the inner L-shaped plate.

[0007] Furthermore, the connecting hole is a strip-shaped hole.

[0009] Furthermore, the adapter plate is a U-shaped adapter plate, one of the side plates of the U-shaped adapter plate is provided with a through hole, and is threadedly connected to one end of the outer L-shaped plate and / or the inner L-shaped plate through the through hole.

[0010] Furthermore, the two side plates of the U-shaped adapter plate are of unequal lengths.

[0011] Furthermore, the distance between the two side plates of the U-shaped adapter plate is 80-160 mm.

[0012] Furthermore, the outer L-shaped plate and the inner L-shaped plate are threadedly connected via the connecting hole.

[0019] For the sake of understanding, the following are the precise definitions of the technical terms that will appear in the following text:

[0020] “Outer side of inner L-shaped plate” means: one side of the bending angle surrounded by the two straight plates of the L-shaped plate is the inner side, and the other side is the outer side.

[0021] The present invention will be further described in detail below in conjunction with specific implementations and with reference to the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application.

[0022] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts unless otherwise specifically stated.

[0023] like Figure 1-4An overhead line signboard mounting bracket shown includes an adapter plate 3 and a clamping mechanism. The clamping mechanism includes two L-shaped plates. The bending angle of the L-shaped plate is the same as the bending angle of the angle steel. The two L-shaped plates are an outer L-shaped plate 6 and an inner L-shaped plate 7. Strip holes are provided at both ends of the outer L-shaped plate 6. The outer L-shaped plate 6 is stacked on the outside of the inner L-shaped plate 7, and corresponding strip holes are provided at both ends of the inner L-shaped plate 7 at positions corresponding to the strip holes at both ends of the outer L-shaped plate 6. Bolts are used to pass through the strip holes 7 of the outer L-shaped plate 6 and the inner L-shaped plate in turn, and then nuts are used to fasten the two L-shaped plates. The side plates of the U-shaped adapter plate 3 are two side plates of different lengths. A through hole is provided in the short side plate, and the through hole is threadedly connected to one end of the outer L-shaped plate 6 and / or the inner L-shaped plate 7. A positioning hole connected to the signboard is provided in the long side plate. The distance between the two side plates of the U-shaped adapter plate 3 should be greater than the width of the angle steel of the assembled iron tower to avoid interference from the angle steel when assembling the signboard. When the inner and outer L-shaped plates are clamped on the inclined angle steel, the fixed angle of the U-shaped adapter plate 3 can be adjusted to ensure that the signboard is in a horizontal position. It is suitable for installing signboards on iron towers of various structures and has a wide range of applications.

[0024] The above technical solution should be operated as follows when working:

[0025] 1) Place the inner side of the outer L-shaped plate 6 close to the outer side of the angle steel, and the outer side of the inner L-shaped plate 7 close to the inner side of the angle steel. At this time, one end of the inner and outer L-shaped plates extend to the inside of the tower, and the other end extends to the outside of the tower. Insert the bolt 8 into the strip hole at the end of the L-shaped plate extending to the inside of the tower. The bolt 8 passes through the outer L-shaped plate 6 and comes out from the strip hole of the inner L-shaped plate 7. Screw in the nut and tighten it.

[0026] 2) On the side where the L-shaped plate extends out of the tower, align the through hole of the short side plate of the U-shaped adapter plate 3 with the bar-shaped holes extending out of the inner and outer L-shaped plates, and use bolts 5 to pass through the inner L-shaped plate 7, the outer L-shaped plate 6, and the U-shaped adapter plate 3 in sequence, screw in the nuts and tighten. In this step, attention should be paid to the selection of the U-shaped adapter plate 3. Since overhead line towers of different voltage levels are of different sizes, the selection of angle steel sizes is also different. The U-shaped adapter plate 3 should be selected according to the width of the angle steel. The distance between the two side plates is greater than the width of the angle steel to avoid the interference of the angle steel set obliquely during the installation of the signboard, which makes it impossible to install the signboard horizontally and affects the viewing effect of the signboard.

[0027] 3) Place the signboard tightly against the long side plate of the U-shaped adapter plate 3, and ensure that the assembly hole of the signboard is aligned with the positioning hole of the long side plate of the U-shaped adapter plate 3, insert the bolts and tighten them, and complete the installation of the signboard. It should be noted in this step that depending on the assembly environment, affected by natural factors such as wind force, the size of the signboard, etc., when the signboard needs to be further fixed, a connecting plate 1 can be added to each positioning hole of the U-shaped adapter plate 3, and connecting holes aligned with the assembly holes of the signboard are opened at both ends of the connecting plate 1. Two of the assembly holes of the signboard are matched with the U-shaped adapter plate 3 and the connecting plate 1 and fixed by bolts (2, 4), and the other two assembly holes are fixed to the connecting plate by bolts.

[0028] In an optional implementation, the adapter plate is a flat plate, and in this solution, the operation during operation is similar to that of the U-shaped adapter plate 3. Although this solution may be interfered by the angle steel during implementation, it is still a feasible technical solution.

[0029] Those skilled in the art will appreciate that numerous variations to the above description are possible, and that the examples and figures are intended only to describe one or more specific implementations.

[0030] Although what is considered as exemplary embodiments of the present invention has been described and described, it will be understood by those skilled in the art that various changes and substitutions may be made thereto without departing from the spirit of the present invention. In addition, many modifications may be made to adapt specific situations to the teachings of the present invention without departing from the central concept of the present invention described herein. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but the present invention may also include all embodiments and their equivalents that fall within the scope of the present invention.
