Description

Technical Field

[0001] The utility model relates to an overhead cable shunt clamp, belonging to the field of overhead cable accessories. Background Art

[0002] High-voltage overhead cable is one of the transmission channels for high-voltage power transmission. When leading out a shunt cable on the overhead cable, a shunt clamp is needed to connect the main cable and the shunt cable, that is, the clamp body in the shunt clamp is clamped on the main cable, and then the shunt cable is connected to the clamp body to complete the connection between the shunt cable and the main cable. The gravity of the long shunt cable will act on the main cable through the clamp body. Due to the small size of the clamp body, the pulling force of the shunt cable on the main cable is concentrated in a small area, which makes the part of the main cable where the shunt cable is installed more likely to be damaged due to the heavy load. Therefore, it is necessary to design an overhead cable shunt clamp that can disperse the pulling force of the shunt cable on the main cable to a large area of the main cable. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an overhead cable shunt clamp to solve the problems raised in the above-mentioned background technology. The present invention disperses the pulling force of the shunt cable on the main cable to a large area of the main cable, preventing the area of the main cable where the shunt cable is installed from being damaged due to the heavy load.

[0004] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: an overhead cable diversion clamp, comprising a clamp body, a side surface of the clamp body is provided with a limiting cavity for inserting a main cable, a side surface of the clamp body is provided with a first screw hole communicating with the limiting cavity, the first nut is internally threadedly connected to a first clamping screw for limiting the relative position of the clamp body and the main cable, the side of the clamp body where the first screw hole is provided is provided with an insertion hole for inserting a diversion cable that is staggered with the first screw hole, the upper surface of the clamp body is evenly provided with a plurality of second screw holes communicating with the insertion holes, the second screw holes are internally threadedly connected to a second clamping screw for limiting the relative position of the clamp body and the diversion cable, a support ear is installed on the side of the clamp body away from the first screw hole, a first through-hole is provided on one side of the support ear, a stud is inserted in the first through-hole, both sides of the support ear are provided with a first nut threadedly connected to the stud, and both ends of the stud are provided with a detachable support member that contacts the main cable for increasing the contact range between the clamp body and the pole.

[0005] Furthermore, the support member includes an arc-shaped plate, and the main cable is clamped with an arc-shaped plate on both sides of the wire clamp body. A connecting ear is fixed to the middle position of the outer surface of the arc-shaped plate, and a second through-hole aligned with the first through-hole is opened on one side of the connecting ear. The end of the stud passes through the second through-hole, and a second nut for limiting the relative position of the stud and the connecting ear is provided on both sides of the connecting ear, and the second nut is threadedly connected to the stud.

[0006] Furthermore, a support rod for limiting the position of the shunt cable is installed on the upper surface of the connecting ear, and a limit plate for limiting the range of movement of the shunt cable is connected and fixed to the upper end of the support rod.

[0007] Furthermore, an outer surface of one end of the support rod away from the limiting plate is processed with an external thread, a second threaded hole is opened on the upper surface of the connecting ear, and the end of the support rod processed with the external thread is threadedly connected to the second threaded hole.

[0008] Furthermore, a threaded head is connected and fixed at the middle position of one end of the stud, a first threaded hole is opened at the middle position of the end of the stud away from the threaded head, and the threaded head on one stud is threadedly connected to the first threaded hole on the other stud.

[0009] Furthermore, a plurality of reinforcing ribs are provided at the connection portion between the support ear and the wire clamp body, and the reinforcing ribs are connected and fixed to the support ear and the wire clamp body.

[0010] Beneficial effects of the utility model:

[0011] 1. Pass the stud through the first through-hole on the lug and use two first nuts to limit the relative position of the stud and the lug, thereby limiting the relative position of the stud and the clamp body. At this time, after the cable holder is installed on the main cable, the stud is arranged along the length direction of the main cable.

[0012] 2. Make the two ends of the stud pass through the second through-holes on the two connecting ears respectively, and then use two nuts to limit the relative position of the stud and the connecting ears, so that arc plates are installed on both ends of the stud. After the relative position of the clamp body and the main cable is restricted, the arc plates at both ends of the stud are clamped on the main cable, and then the pulling force of the shunt cable on the main cable through the clamp body is dispersed over a large area of the main cable, preventing the area of the main cable where the shunt cable is installed from being damaged due to heavy load.

[0013] 3. Screw the threaded head on one stud into the first threaded hole on another stud to realize the assembly of two adjacent studs. Similarly, realize the assembly of multiple studs, and install a structure formed by a connecting ear and an arc plate on each stud, so that the pulling force of the shunt cable on the main cable is dispersed on the main cable to increase the range.

[0014] 4. After installing one end of the shunt cable on the clamp body, make the end of the shunt cable close to the clamp body alternately pass around the support rods on multiple connecting ears in an S shape. At this time, the support rod, limit plate and connecting ear jointly limit the part of the shunt cable close to one end of the main cable, so that the gravity of the shunt cable acts on the main cable through the support rod, limit plate, connecting ring and arc plate, preventing the connection part between the shunt cable and the clamp body from falling off due to pulling force.

[0023] See Figure 1 and Figure 2 The first screw hole 14 is provided on one side of the wire clamp body 1, and an insertion hole 3 for inserting the shunt cable is provided, which is staggered with the first screw hole 14.
