Description

Technical Field

[0001] This utility model relates to the field of fixed wire clamp technology, specifically a pre-twisted anti-fatigue fixed wire clamp. Background Technology

[0002] Pre-twisted fatigue-resistant clamps are a specially designed type of clamp, mainly used in power lines, to prevent fatigue-induced wire breakage and strand breakage caused by vibration.

[0003] Utility model patent CN220548963U discloses a pre-stranded anti-fatigue fixing clamp for tunnels, which is used in conjunction with pre-stranded wire and a pad. The clamp includes an upper cover, a lower seat, and vertical or horizontal fixing bolts. The upper cover and the lower seat cooperate to clamp the pad and the pre-stranded wire. The lower seat is provided with a vertical or horizontal bolt fixing seat. The vertical fixing bolt passes through the vertical bolt fixing seat to achieve vertical installation and fixing, and the horizontal fixing bolt passes through the horizontal bolt fixing seat to achieve horizontal installation and fixing.

[0004] The above technical solution provides two structural forms of wire clamps, which can meet the needs of fixed installation in the vertical or horizontal direction. They have advantages such as quick installation, wear and shock absorption, avoidance of stress concentration, and extension of wire service life. However, when fixing wire clamps with pre-twisted protective wires to hold and fix cables of different sizes, it is not convenient to make stable adjustments and fits. In addition, it is not convenient to open or close the wire clamps. Utility Model Content

[0005] The purpose of this utility model is to provide a pre-twisted anti-fatigue fixing clamp to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pre-twisted fatigue-resistant fixing clamp includes two sets of clamp assemblies. Each set of clamp assemblies consists of a lower clamp plate and an upper clamp plate that is movably connected to the lower clamp plate. A first connecting block is symmetrically provided at the left end of the lower clamp plate, and a protrusion is provided at the right end of the lower clamp plate. A first screw hole is opened on the top of each protrusion. A connecting frame is provided above each of the first connecting blocks. A screw is provided at both ends of each connecting frame. A positioning nut is fitted on the top of each screw. A positioning rod is provided between the two connecting frames. A second connecting block is provided at the left end of the upper clamp plate. A sliding hole is opened on the second connecting block at the position corresponding to the screw. A protrusion is provided at the right end of the upper clamp plate. A through hole is opened on the protrusion plate at the position corresponding to the first screw hole. A positioning bolt is provided in each through hole.

[0008] Furthermore, each of the inner walls of the lower clamping plate is provided with a lower rubber pad, and the lower surface of the lower rubber pad is engaged with the lower clamping plate at the middle.

[0009] In this invention, the lower rubber pad and the lower clamping plate work together to increase the friction between the lower clamping plate and the pre-twisted protective line, which helps to stabilize the clamping and fixing.

[0010] Specifically, each of the inner walls of the upper clamping plate is provided with an upper rubber pad, and the upper surface of the upper rubber pad is engaged with the upper clamping plate at the middle.

[0011] In this invention, the upper rubber pad and the upper clamping plate work together to increase the friction between the upper clamping plate and the pre-twisted protective line, which facilitates stable clamping of the pre-twisted protective line and increases the stability of the installation.

[0012] It should be noted that an arc-shaped groove is provided in the middle of the inner wall of the upper clamping plate, an adjusting plate is provided in the arc-shaped groove, a second screw hole is provided in the middle of the arc-shaped groove, an adjusting rod is provided in the second screw hole, and a disc is provided at the bottom of the adjusting rod, and the disc is rotatably connected to the adjusting plate.

[0013] In this invention, the adjusting rod is threadedly connected to the second screw hole. Rotating the adjusting rod causes the adjusting plate to move downward, thereby pushing the upper rubber pad to fit tightly against the pre-twisted protective line, increasing the stability of the clamping and fixing. The adjusting plate fits tightly against the arc groove, which helps to clamp the large-diameter pre-twisted protective line tightly.

[0014] Furthermore, the convex plate and the upper clamping plate are integrally formed, the positioning bolt passes through the through hole and is threadedly connected to the first screw hole, the second connecting block and the upper clamping plate are integrally formed, the inner diameter of the sliding hole is adapted to the outer diameter of the screw, and the positioning nuts are all located above the second connecting block.

[0015] In this utility model, the positioning nut is threadedly connected to the screw, and the second connecting block is slidably engaged with the screw. When the positioning nut moves downward, the upper clamping plate and the lower clamping plate move closer to each other. With the positioning bolt threadedly connected to the first screw hole, the upper clamping plate and the lower clamping plate move closely together to fix and clamp the cable wound with the pre-twisted protective wire.

[0016] Specifically, the protrusion and the lower clamping plate are integrally formed, the first connecting block and the lower clamping plate are integrally formed, and the top of the first connecting block is welded and fixed to the bottom of the corresponding screw.

[0017] In this invention, the first connecting block is welded to the screw to increase the structural stability of the assembly.

[0018] Secondly, the connecting frame is U-shaped, and both ends of the connecting frame are welded and fixed to the top of the corresponding screw.

[0019] In this invention, the connecting frame fixes the top position of the screw, increasing the stability of the screw and the lower clamping plate assembly.

[0020] It is worth noting that the positioning rod is U-shaped, and its two ends are welded and fixed to the middle of the corresponding connecting frame. A fixing plate is provided in the middle of the positioning rod, and the fixing plate is welded and fixed to the positioning rod. Several positioning holes are provided on the fixing plate.

[0021] In this invention, the positioning rod enables a stable connection between two sets of wire clamp components. With the help of a fixing plate with multiple positioning holes, the positioning rod can be fixed in position by passing through the positioning holes with external screws or steel wires.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. This utility model sets up two sets of wire clamp assemblies, and with the cooperation of the connecting frame and the positioning rod, the two lower clamps are fixed by screws, which increases the stability of the assembly. Each lower clamp is fitted with an upper clamp, and the upper clamp is slidably engaged with the screw through the second connecting block. With the cooperation of the positioning nut, the distance between the upper and lower clamps can be adjusted, which helps to clamp cables with different diameters of pre-twisted protective wire. With the cooperation of the positioning bolt, the clamping and fixing of the wound cable is further enhanced, which helps to manually clamp and fix it.

[0024] 2. This utility model, through the cooperation of the upper and lower rubber pads, allows the lower clamping plate to fit close to the upper clamping plate, increasing the friction with the cable wound with the pre-twisted protective wire, while reducing the impact of clamping damage to the cable wound with the pre-twisted protective wire. The upper clamping plate is equipped with a rotatable adjusting rod, which, with the cooperation of the adjusting plate, helps to clamp and cooperate with the cable wound with the pre-twisted protective wire of small diameter. The downward movement of the adjusting plate causes the upper rubber pad to move downward, thereby achieving a tight clamping fit. Attached Figure Description
