Description

Technical Field

[0001] The utility model relates to the technical field of cable fixing clips, in particular to a vertical cable fixing clip device for tower cranes. Background Technique

[0002] Tower cranes are the most commonly used lifting equipment on construction sites. The operation of tower cranes relies on cables for power transmission. At present, in most construction sites, the cable fixing device of tower cranes generally uses crossbeams and insulating porcelain insulators to fix the cables. The crossbeam is mainly used to fix the cables, and the insulating porcelain insulators are used to isolate and insulate the cables from the standard sections of the tower crane. The cable insulators bear the vertical load and tension of the cables through the crossbeams, and the porcelain insulators have very reliable insulation performance. However, its fixing method is mainly through binding, which has the problem of insecure fixing in terms of use, and the appearance is rough due to multi-strand tie binding. The insulating porcelain insulator is a cylinder, which fixes the cable, making the cable not straight vertically and not beautiful. Content of the Utility Model

[0003] Aiming at the above problems in the prior art, the utility model provides a vertical cable fixing clip device for tower cranes, which solves the problems that the existing tower crane cable fixing structure fixes the cable insecurely and affects the appearance of the tower crane.

[0004] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0005] A vertical cable fixing clip device for tower cranes is provided, which includes a U-shaped fixing plate for clamping on the standard section of the tower crane. The U-shaped fixing plate includes a flat support plate. Two first side plates and second side plates are respectively fixed at both sides of the bottom of the flat support plate. Two threaded holes for cooperating with bolts are respectively opened at the bottom ends of the end faces of the first side plates and the second side plates. One ends of two bolts sequentially pass through the first side plates and the second side plates and are bolt-connected to the fixing clip. The fixing clip is located on the second side plate, and a cable hole for the cable to pass through is vertically opened in the middle of the fixing clip.

[0006] The working principle of this scheme is as follows: First, the U-shaped fixing plate is clamped on the standard section of the tower crane, and then the U-shaped fixing plate is restricted on the standard section by two bolts. At the same time, the two bolts fix the fixing clip on the U-shaped fixing plate. Finally, the cable is vertically passed through the cable hole on the fixing clip to complete the fixing of the cable. Compared with binding the cable insulator with a tie, this scheme is not only more beautiful, ensures the verticality of the cable, but also has higher structural strength and is not easy to break, enabling the cable to be more firmly fixed on the tower crane.

[0007] Further, the fixing clip includes a fixing block and a clamping block. A U-shaped groove is vertically formed at one end of the fixing block close to the second side plate. The clamping block is horizontally slidably arranged on both side walls of the U-shaped groove. The clamping block is in the shape of a U-shaped block, and the opening of the clamping block and the opening of the U-shaped groove form a cable hole. When the diameter of the cable is large, the clamping block can move away from the fixing block, increasing the diameter of the cable hole and improving the adaptability of the cable hole.

[0008] Further, cylindrical protrusions are provided on both sides of the fixing block. Through holes for bolts to pass through are formed inside both protrusions. Two bolts respectively pass through the two through holes and are bolt-connected to nuts.

[0009] Further, a spring washer is arranged between the nut on each bolt and the protrusion. The spring washer can provide a continuous pressure through its elastic characteristics, preventing the nut from loosening due to vibration or other factors during use, and helping to ensure the stability and reliability of the connection.

[0010] Further, the nominal diameter of both bolts is 10 mm.

[0011] Further, the length of the two bolts is 20 mm to 200 mm.

[0012] Further, the width of the flat support plate of the U-shaped fixing plate is 50 mm to 110 mm. Setting the width of the U-shaped fixing plate in this way can meet the flat support widths of mainstream tower cranes such as Zoomlion, Sany, and XCMG.

[0013] Further, the materials of the U-shaped fixing plate, bolts, nuts, and spring washers are all galvanized steel. The galvanized layer on the galvanized steel has an anti-corrosion effect.

[0014] Further, the material of the fixing clip is insulating rubber.

[0015] The utility model discloses a vertical cable fixing clip device for a tower crane, and its beneficial effects are as follows:

[0016] The utility model fixes the fixing clip on the standard section of the tower crane through the U-shaped fixing plate, and the cable vertically passes through the cable hole on the fixing clip to complete the fixing of the cable. As a result, the fixing of the cable is not only more beautiful, ensuring the verticality of the cable, but also the structural strength of the U-shaped fixing plate and the fixing clip is higher than that of the cable tie and is not easily broken, enabling the cable to be more firmly fixed on the tower crane.

[0021] The following describes the specific embodiments of the present invention to facilitate the understanding of the present invention by those skilled in the art. However, it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all utility models created using the concept of the present invention are within the scope of protection

[0022] Refer to Figures 1 to 3 , this embodiment provides a vertical cable fixing clip device for tower crane, including a U-shaped fixing plate 1 and a fixing clip 2

[0023] Refer to Figure 1 , the U-shaped fixing plate 1 is used to be clamped on the tower crane standard section. The U-shaped fixing plate 1 includes a flat support plate 13. Two first side plates 11 and second side plates 12 are respectively fixed at both sides of the bottom of the flat support plate 13. Two threaded holes for cooperating with the bolt 3 are opened on the bottom ends of the end faces of the first side plate 11 and the second side plate 12. One end of two bolts 3 sequentially passes through the first side plate 11 and the second side plate 12 and is bolted to the fixing clip 2

[0024] The fixing clip 2 is located on the second side plate 12, and a cable hole 23 for the cable to pass through is vertically opened in the middle of the fixing clip 2. Specifically, the fixing clip 2 includes a fixing block 21 and a clamping block 22. A U-shaped groove is vertically opened at one end of the fixing block 21 close to the second side plate 12. The clamping block 22 is horizontally slidably arranged on both side walls of the U-shaped groove. The clamping block 22 is in the shape of a U-shaped block, and the opening of the clamping block 22 and the opening of the U-shaped groove form the cable hole 23. When the cable diameter is large, the clamping block 22 can be far away from the fixing block 21 to make the diameter of the cable hole 23 larger, improving the adaptability of the cable hole 23. The cable hole 23 of this embodiment can be used for a 5-core cable with a cable cross-sectional area of 16 - 70mm 2 ²

[0025] In order to facilitate the connection of the bolt 3, cylindrical protrusions are arranged on both sides of the fixing block 21. Through holes for the bolt 3 to pass through are opened inside the two protrusions. Two bolts 3 respectively pass through the two through holes and are bolted to the nut 4

[0026] To improve the connection stability, a spring washer 5 is provided between the nut 4 on each bolt 3 and the protrusion. The spring washer 5 can provide a continuous pressure through its elastic property, preventing the nut 4 from loosening due to vibration or other factors during use, which helps to ensure the stability and reliability of the connection.

[0027] In this embodiment, the nominal diameters of the two bolts 3 are both 10 mm. The lengths of the two bolts 3 are 20 mm to 200 mm. The width of the flat support plate 13 of the U-shaped fixing plate 1 is 50 mm to 110 mm. By setting the width of the U-shaped fixing plate 1 in this way, the flat support widths of mainstream tower cranes such as Zoomlion, Sany, and XCMG can be satisfied. Moreover, the materials of the U-shaped fixing plate 1, bolts 3, nuts 4, and spring washers 5 are all galvanized steel. The galvanized layer on the galvanized steel has an anti-corrosion effect. The material of the fixing clip 2 is insulating rubber.

[0028] In summary, the working principle of this solution is as follows:

[0029] First, the U-shaped fixing plate 1 is clamped on the standard section of the tower crane, and then the U-shaped fixing plate 1 is restricted on the standard section by two bolts 3. At the same time, the two bolts 3 fix the fixing clip 2 on the U-shaped fixing plate 1. Finally, the cable is vertically passed through the cable hole 23 on the fixing clip 2 to complete the fixing of the cable. Compared with tying the cable with cable ties on the cable insulator, this solution is not only more beautiful, ensuring the verticality of the cable, but also has higher structural strength and is not easily broken, enabling the cable to be more firmly fixed on the tower crane.

[0030] Although the specific implementation manners of the utility model have been described in detail in conjunction with the accompanying drawings, it should not be construed as a limitation on the protection scope of this patent. Within the scope described in the claims, various modifications and deformations that can be made by those skilled in the art without creative efforts still fall within the protection scope of this patent.
