Description

Technical Field

[0001] This utility model relates to the field of power tower angle steel connection technology, specifically to a quick-connect plate for tower angle steel. Background Technology

[0002] Power transmission towers are crucial supporting structures in power transmission systems, primarily used to erect high-voltage transmission lines and ensure stable power transmission. Towers typically consist of components such as angle steel, connecting plates, and bolts, with the angle steel serving as the main load-bearing component, and are spliced ​​and reinforced by connecting plates. Power transmission towers must possess high strength, wind load resistance, and corrosion resistance to ensure long-term stable operation.

[0003] Traditional methods of connecting angle steel for iron towers often use ordinary connecting plates and bolts for fixing. When using them, the angle steel needs to be manually aligned with the connecting holes, which is difficult to adjust, especially in confined spaces or when working at heights. This process is time-consuming and prone to falling. In addition, ordinary connecting plates lack limiting structures, allowing the angle steel to slide before the bolts are tightened, affecting installation accuracy. Utility Model Content

[0004] This utility model provides a quick-connect plate for steel tower angle steel, which aims to solve the problems of difficult adjustment, easy falling off and low installation efficiency of traditional connection methods.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is a quick-connecting plate for iron tower angle steel, including a connecting plate body, and the connecting plate body is a right-angled structure composed of two wing plates, with positioning grooves matching the outline of the angle steel on the inner side of the two wing plates.

[0006] The wing plate has an inwardly extending limiting flange at the end of the positioning groove, forming a U-shaped sliding snap-fit ​​structure with the wing plate;

[0007] The wing plate is provided with symmetrically distributed bolt hole groups, which are a combination of inclined strip holes and round holes;

[0008] A partition rib is provided in the middle of the connecting plate body at the positioning groove, and the partition rib is provided with a vertical limiting rib at the positioning groove of the two wing plates.

[0009] As a preferred technical solution of this utility model, the connecting plate body is made of Q420 high-strength steel, and the surface is hot-dip galvanized, with a zinc layer thickness of not less than 80μm.

[0010] As a preferred technical solution of this utility model, the inner surface of the positioning groove is provided with anti-slip texture, the texture depth is 0.5-1mm, and the texture direction is arranged at a 60° intersection with the axis of the angle steel.

[0011] As a preferred technical solution of this utility model, the two ends of the connecting plate body are provided with inwardly inclined guide slopes at the positioning groove and the limiting flange, the inclination angle of the guide slope is 30 degrees-45 degrees, and the width of the guide slope is less than or equal to 1 / 2 of the thickness of the limiting flange.

[0012] As a preferred embodiment of this utility model, the bolt hole group is located on one side of the wing plate and consists of a single strip hole and round holes on both sides.

[0013] As a preferred technical solution of this utility model, the central axis of the strip hole forms an angle of 15-30 degrees with the horizontal direction, and countersunk grooves are provided at both ends of the hole in the length direction.

[0014] As a preferred technical solution of this utility model, the circular hole and the wing plate are inclined at 45 degrees, and the circular holes on both sides of the strip hole are symmetrically arranged with respect to the center of the axis in the middle of the strip hole.

[0015] As a preferred technical solution of this utility model, the partition rib is a triangular plate that is perpendicular to the connecting plate body, and the two ends of the partition rib match the shape of the positioning groove and the limiting flange. The thickness of the partition rib matches that of the wing plate.

[0016] As a preferred technical solution of this utility model, the limiting rib is an L-shaped plate, and the two ends near the wing plate are provided with snap-fit ​​grooves with the same thickness as the angle steel.

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] 1. The quick-connect plate for angle steel of this iron tower uses a U-shaped snap-fit ​​structure and guide slope design to enable the angle steel to be quickly inserted. The intermediate partition rib and limit rib can quickly pre-position the plate, reducing the adjustment time during installation and preventing the plate from falling off, thereby effectively improving the safety of high-altitude operations.

[0019] 2. The quick-connect plate for the angle steel of this iron tower prevents the angle steel from sliding during installation by using anti-slip texture and limiting flange, and increases the friction during the later installation process. At the same time, the inclined bolt hole group reduces stress concentration and extends service life. Attached Figure Description

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Example 1:

[0029] As per the instruction manual Figure 1-4 As shown, a quick-connecting plate for tower angle steel includes a connecting plate body 1. The connecting plate body 1 is made of Q420 high-strength steel, with hot-dip galvanized surface treatment and a zinc layer thickness of not less than 80μm. The connecting plate body 1 is a right-angled structure composed of two wing plates 2. The inner side of the two wing plates 2 is provided with positioning grooves 3 that match the contour of the angle steel. The inner surface of the positioning grooves 3 is provided with anti-slip textures 10 with a texture depth of 0.5-1mm and the texture direction is arranged at a 60° intersection with the axis of the angle steel.

[0030] In this utility model, the wing plate 2 has an inwardly extending limiting flange 4 at the end of the positioning groove 3, forming a U-shaped sliding snap-fit ​​structure with the wing plate 2, so that the angle iron can be inserted into the positioning groove 3. The two ends of the connecting plate body 1 are provided with inwardly inclined guide slopes 11 at the positioning groove 3 and the limiting flange 4. The inclination angle of the guide slope 11 is 30 degrees, and the width of the guide slope 11 is less than or equal to 1 / 2 of the thickness of the limiting flange 4.

[0031] In this utility model, the wing plate 2 is provided with symmetrically distributed bolt hole groups 5. The bolt hole group 5 is a combination of inclined strip holes 6 and round holes 7. The bolt hole group 5 is located on one side of the wing plate 2 and consists of a single strip hole 6 and round holes 7 on both sides. The central axis of the strip hole 6 is at a 25-degree angle to the horizontal direction, and countersunk grooves 12 are provided at both ends of the hole length direction to facilitate bolt adjustment and weight reduction. At the same time, the inclined strip hole 6 can distribute the load of the angle iron at the same height when fixed. The round holes 7 are inclined at 45 degrees to the wing plate 2, and the round holes 7 on both sides of the strip hole 6 are symmetrically arranged with the central axis of the strip hole 6. The central axis of the strip hole 6 is the intersection of the middle of the line connecting the two ends of the strip hole 6 and the horizontal direction, that is, the two round holes 7 face one direction upward and the other direction downward.

[0032] In this utility model, a partition rib 8 is provided in the middle of the connecting plate body 1 at the positioning groove 3. The partition rib 8 is a triangular plate that is perpendicular to the connecting plate body 1. The two ends of the partition rib 8 match the shape of the positioning groove 3 and the limiting flange 4. The thickness of the partition rib 8 matches that of the wing plate 2. The partition rib 8 is provided with a vertical limiting rib 9 at the positioning groove 3 of the two wing plates 2. The limiting rib 9 is an L-shaped plate, and the two ends are provided with a snap-fit ​​groove 13 with the same thickness as the angle steel at the position close to the wing plate 2. The snap-fit ​​groove 13 can abut against the inner side of the angle steel to distribute the load at the connection between the angle steel and the connecting plate.

[0033] In specific implementation, the angle steel is pushed into the positioning groove 3 of the U-shaped snap-fit ​​structure along the guide slope 11, and the anti-slip texture 10 on the inner side prevents slippage. One end of the angle steel automatically abuts and aligns with the snap-fit ​​groove 13 on the partition rib 8 and the limiting rib 9, thereby directly determining the position of the screw hole, the strip hole 6 and the round hole 7 on the angle steel, and fixing is completed by the installation bolts. At the same time, the partition rib 8 and the limiting rib 9 jointly distribute the load to avoid excessive local stress and ensure reliable connection. The snap-fit ​​groove 13 of the reinforcing rib is used to position the top of the connected angle steel, further fixing the angle steel.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
