Description

Technical Field

[0001] The invention relates to the technical field of electric auxiliary devices, and in particular to a cold-bent weathering steel rust layer protection clamp. Background Art

[0002] Weathering steel towers have the advantages of no galvanizing, environmental protection, corrosion resistance, and low comprehensive energy consumption. In order to reduce operation and maintenance costs and protect the environment, countries around the world are actively developing and promoting the application of weathering steel materials. The corrosion rate of weathering steel materials exposed to the air is much higher than that of ordinary steel materials, but after the initial rust, a dense rust layer will form on its surface, which will prevent further rust of the tower.

[0003] During maintenance work, it is necessary to use ropes to fix the pulleys to the crossarms of the towers to transfer tools or accessories up and down. Due to the heavy weight of the transferred items, even if the rust layer on the surface of the weathering steel tower is dense, the repeated friction of the hanging ropes will still cause wear and tear on the dense rust layer and even cause it to fall off. In addition, during maintenance work, tools or accessories are often fixed to the crossarms with clamps to avoid the risk of falling from heights. At this time, the fixing clamps will also damage the rust layer.

[0004] After the rust layer is worn off, the weathering steel tower will be exposed to the air again, causing corrosion problems and forming pit defects on the tower. The pit defects will cause stress concentration in the tower, significantly reducing the mechanical strength and service life of the tower, and causing certain safety hazards.

[0028] The embodiment of the present application provides a cold-bent weathering steel rust layer protection clamp, which solves the technical problem that the existing clamp fixed on the cross arm of the weathering steel pole tower will cause the rust layer on the surface to wear.

[0029] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Example

[0031] Cold-bent weathering steel rust protection clamps, such as Figure 1 As shown, it includes a clamping component 1, a first wear-resistant layer 2, an arc plate 3, a second wear-resistant layer 4, a rope limiter 5 and a positioning component 6.

[0032] Combination Figure 2As shown, the clamping assembly 1 includes a first bracket 11, a second bracket 12, a rotating shaft 13 and a bent plate 14. The first bracket 11 and the second bracket 12 are integrally connected through the bent plate 14. The first bracket 11 is L-shaped in a normal state, and the second bracket 12 is an L-shaped bracket. A hollow L-shaped area is formed between the first bracket 11 and the second bracket 12, and the cross arm is clamped inside the L-shaped area, so as to fix the cross arm for subsequent related operations.

[0033] The first bracket 11 includes a first vertical plate 111 and a first bottom plate 112. The first vertical plate 111 is made of aluminum alloy and is arranged perpendicular to the horizontal plane. The second bottom plate 122 is also made of aluminum alloy and is arranged parallel to the horizontal plane under normal conditions. A rotating shaft 13 is connected between the first vertical plate 111 and the first bottom plate 112, and the first bottom plate 112 can rotate along the rotating shaft 13. When the cross arm is to be clamped in the L-shaped area, the first bottom plate 112 is first rotated downward to reserve enough clamping space for the cross arm, and then the first bottom plate 112 is rotated back to a state parallel to the horizontal plane, thereby clamping the cross arm.

[0034] The second bracket 12 includes a second vertical plate 121 and a second bottom plate 122. The second vertical plate 121 is made of aluminum alloy, is arranged perpendicular to the horizontal plane, and is parallel to the first vertical plate 111. The second bottom plate 122 is also made of aluminum alloy, is located above the first bottom plate 112, and is arranged parallel to the horizontal plane.

[0035] The bent plate 14 is made of aluminum alloy material, and integrally connects the top of the first vertical plate 111 and the top of the second vertical plate 121. The first wear-resistant layer 2 is made of high molecular polyethylene material, and has excellent wear resistance, and is arranged on the inner wall of the first vertical plate 111, the bent plate 14, the second vertical plate 121, and the upper surface of the first bottom plate 112. The first wear-resistant layer 2 is wrapped on the surface of the above structure by injection molding.

[0036] The arc plate 3 is a 1 / 4 arc structure, one end of which is integrally connected to the top of the bent plate 14 and the second vertical plate 121, and the other end is integrally connected to the edge of the second bottom plate 122 and the second vertical plate 121. The hollow structure between the arc plate 3 and the second bracket 12 is conducive to reducing the weight of the clamp, and when the rope is placed on the arc plate 3, the stress on the protective clamp can be evenly dispersed to avoid deformation of the protective clamp, so as to improve the stability and reliability of the protective clamp.

[0037] The first vertical plate 111 , the curved plate 14 , the second vertical plate 121 , the second bottom plate 122 , and the curved plate 3 are an integrated structure manufactured by a metal 3D printing process.

[0038] The second wear-resistant layer 4 is made of high molecular polyethylene material with excellent wear resistance, and is arranged on the outer wall of the first vertical plate 111 and the arc plate 3 to reduce the friction of the rope on the protective clamp. The second wear-resistant layer 4 is also wrapped on the surface of the above structure by injection molding.

[0039] The rope stopper 5 is made of aluminum alloy material, and has a 1 / 4 arc-shaped cross section. It is located at both ends of the length direction of the arc plate 3. Its arc structure is co-centered with the arc of the arc plate 3. Like the above structure, it is integrally connected to the top of the first vertical plate 111 and the edge of the second bottom plate 122 away from the second vertical plate 121 through metal 3D printing. The rope stopper 5 is used to limit the movement of the rope and prevent the rope from sliding off the arc plate 3, thereby improving the stability of the rope.

[0040] There are two groups of positioning components 6, which are respectively arranged below the two rope stoppers 5. The positioning components 6 include countersunk screws 61, butterfly nuts 62 and washers 63. The edge end of the second bottom plate 122 away from the second vertical plate 121 is provided with a screw hole, and the countersunk screws 61 pass through the screw hole and are arranged perpendicular to the horizontal plane. The butterfly nuts 62 are screw-matched with the countersunk screws 61 through the threads on the surface of the countersunk screws 61, and are arranged below the first bottom plate 112. The washers 63 are arranged at the lower surface of the second bottom plate 122 to prevent the countersunk screws 61 from loosening.

[0041] The working principle of the protective clamp of the present invention is as follows: the positioning can be released by rotating the butterfly nut 62, and the first base plate 112 is then rotated through the rotating shaft 13. After rotating to a suitable position, the clamping assembly 1 of the protective clamp is in an open state, the cross arm is installed in the L-shaped hollow area of ​​the clamping assembly 1, and then the first base plate 112 is rotated back to a horizontal state, and the butterfly nut 62 is tightened to fix the cross arm in the protective clamp. During the construction process, the wear of the rust layer on the surface of the cross arm can be significantly improved.

[0042] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0043] 1. The protective clamp provided in the present invention comprises a clamping assembly and a positioning assembly, wherein the clamping assembly is used to fix the cold-bent weathering steel cross arm, and the positioning assembly is used to fix the protective clamp. The first wear-resistant layer and the second wear-resistant layer are made of high-molecular polyethylene with excellent wear resistance, which is beneficial to prevent the metal structure of the existing clamp from damaging the rust layer of the cold-bent weathering steel;

[0044] 2. The protective clamp of the present invention has strong stability, can effectively protect the rust layer of cold-bent weathering steel, reduce the maintenance cost of weathering steel towers, and has good social benefits.
