Description

Technical Field

[0001] The utility model belongs to the technical field of tension wire clamps, in particular to a large-grip-force tension wire clamp. Background Art

[0002] With the continuous development of the power industry, the stability and safety of overhead lines, as an important part of power transmission, are increasingly valued. As an important connecting component in overhead lines, the performance of tension clamps directly affects the reliability and service life of the lines.

[0003] After searching, the patent with announcement number CN212063411 U provides a new type of bolt-type tension clamp, which relates to the field of tension clamps. It includes a bolt-type tension clamp body, the bottom of which is fixedly installed with a bolt-type tension clamp fixing ear, and a first bolt pin hole is opened inside the bolt-type tension clamp fixing ear. The new type of bolt-type tension clamp, by setting the bolt-type tension clamp pressure strip, tension clamp U-shaped bolt, nut, spring washer, flat washer and inner stripe, makes the wire clamping part of the bolt-type tension clamp more firm during use. The new type of bolt tension clamp has a simple structure, is sturdy and durable, and by setting the hexagonal head with pin hole bolts, enlarged flat washers, closed pins and bolt-type tension clamp fixing ears, the designed hollow fixing bolt can not only firmly fix the steel cable, but also facilitate the removal of the steel cable, so that the bolt-type tension clamp is easy to adjust and improve construction efficiency.

[0004] Traditional tension clamps often have problems such as insufficient gripping force, which leads to poor cable fixing effect. Especially in harsh environments such as strong winds and vibrations, the cables are prone to loosening or even falling off, which poses a hidden danger to the stable operation of the power system. At the same time, traditional bolt-type tension clamps require multiple bolts to be tightened when fixing cables, which is cumbersome and not conducive to improving work efficiency.

[0028] Example 1

[0029] See also Figure 1-4 As shown, in this embodiment, a large gripping force tension clamp is provided, which is used in the field of tension clamp technology, including:

[0030] The main body 1 of the tension clamp is L-shaped for easy installation and fixing. A cable groove 4 is provided on one side of the main body 1 of the tension clamp for placing cables to ensure that the cables are in a stable state when fixed.

[0031] In order to achieve a stable installation of the tension clamp body 1, two mounting parts 2 are designed on one side of the tension clamp body 1, and the two mounting parts 2 are integrally arranged at the bend of the tension clamp body 1. A same mounting bolt 3 is arranged between the two mounting parts 2, and by tightening and clamping the mounting bolt 3, the tension clamp body 1 can be easily installed and fixed at a specified position.

[0032] In order to firmly fix the cables in the cable trough 4, a fixing assembly is designed. The fixing assembly includes a plurality of pressing blocks 8, which are arranged in the cable trough 4. Slide blocks 10 are fixedly installed on the outer walls of both sides of each pressing block 8, and the inner wall of the cable trough 4 is correspondingly provided with a sliding groove that matches the slide block 10. This design enables the plurality of pressing blocks 8 to slide on the inner wall of the cable trough 4, and facilitates the position adjustment to adapt to cables of different diameters.

[0033] The bottom of the pressing block 8 is provided with a groove to increase the contact area with the outer wall of the cable, thereby increasing the friction and improving the fixing effect. At the top of the pressing block 8, a limit groove 9 is provided, and a fixing rod 12 is arranged in these limit grooves 9. A plurality of fixing blocks 6 are fixedly installed on both sides of the tension clamp body 1, and both ends of the fixing rod 12 pass through the corresponding fixing blocks 6. Two fixing rings 13 are fixedly installed on the outer wall of the fixing rod 12, and these fixing rings 13 are located above the fixing block 6 and correspond to the fixing block 6. A pressing plate 16 is also provided on both sides of the tension clamp body 1, and one end of the plurality of fixing rods 12 on the same side slides through the same pressing plate 16. When the pressing plate 16 is pressed, it will fit tightly with the fixing ring 13, and then the pressing plate 16 and the corresponding fixing block 6 can be fastened and clamped by the fixing bolt 17, thereby realizing the downward pressing and fixing of the plurality of fixing rods 12. This design makes the fixing process simple and quick, and the fixing effect is firm and reliable.

[0034] Example 2

[0035] Reference Figure 2 , 3 4. Improvements based on Example 1:

[0036] In order to adjust the pressing pressure of the fixing rods 12, the outer walls of the fixing rods 12 near both ends are provided with threads, and the threads are sleeved with adjusting nuts 15. Compression springs 14 are sleeved at both ends of the fixing rods 12, one end of the compression springs 14 is tightly attached to the bottom of the fixing block 6, and the other end is tightly attached to the top of the adjusting nut 15. By adjusting the position of the adjusting nut 15, the compression degree of the compression spring 14 can be adjusted, thereby achieving fine adjustment of the pressing pressure of the fixing rods 12.

[0037] In order to improve the stability of cable fixing, a plurality of first arc-shaped convex strips 5 are fixedly installed on the bottom inner wall of the cable groove 4, and a second arc-shaped convex strip 11 is fixedly installed in the bottom groove of the pressing block 8. These first arc-shaped convex strips 5 cooperate with the second arc-shaped convex strips 11 to enhance the contact friction between the bottom of the pressing block 8, the inner wall of the cable groove 4 and the cable, and prevent the cable from sliding or loosening during the fixing process.

[0038] In addition, a plurality of clearance grooves 7 are provided on the top of the tension clamp body 1 , and these clearance grooves 7 provide clearance space for the fixing rod 12 to avoid interference when the fixing rod 12 presses and fixes the pressing block 8 .

[0039] In practical applications, in order to ensure that the pressing force at both ends of the pressing plate 16 is the same, at least two pressing blocks 8 and fixing rods 12 are provided, and the fixing bolt 17 is located at the center of the pressing plate 16, and there is at least one fixing rod 12 on either side. Such a design ensures that the pressing plate 16 can apply force evenly when fixed, thereby improving the stability and reliability of the fixation.

[0040] The use process and working principle of the technical solution of this utility model are as follows:

[0041] When in use, the user can pass one end of the cable into the cable groove 4. The cable should be located below the pressing block 8 during installation. Then, the cable can be passed out from the other end along the cable groove 4 to complete the installation of the cable. Then, the user can directly use the two fixing bolts 17 to lock and fix the pressing plates 16 on both sides. The two pressing plates 16 can press the fixing rings 13 on both sides to descend, so that the fixing rod 12 can press and fix the pressing block 8 tightly, and finally multiple pressing blocks 8 can complete the fixation of the cable. The bottom of the pressing block 8 and the inner wall of the cable groove 4 are respectively provided with a second arc-shaped convex strip 11 and a first arc-shaped convex strip 5, which can further improve The pressing effect on the cable, since the fixing bolts 17 and the pressing plate 16 are directly used to fix the multiple fixing rods 12, the number of bolts that need to be tightened can be effectively reduced, and the installation efficiency can be improved; since the two ends of the multiple fixing rods 12 are provided with compression springs 14 and adjusting nuts 15, a downward pulling force can be further applied to the fixing rods 12 to improve the fixing effect of the fixing rods 12 on the pressing block 8. At the same time, the user can compress or relax the compression spring 14 by rotating the adjusting nut 15, so as to adjust the downward pulling force on the fixing rod 12 and balance the force on both ends of the fixing rod 12 to ensure a better fixing effect on the cable.
