A jumper suspension clamp

Abstract

This invention discloses a jumper suspension clamp, comprising a wire groove, two mounting slots on the side wall of the wire groove, and detachable connecting blocks installed in the two mounting slots. Two wire clamping mechanisms are symmetrically installed on the side wall of each connecting block, and a degree-of-freedom connecting member is installed on the top. This invention relates to the field of power distribution hardware technology. This invention solves the problems of traditional jumper suspension clamps, which typically use a U-bolt with two nuts to clamp the wire clamp body, making operation inconvenient and prone to loosening; and traditional jumper suspension clamps, which are usually rotatable in one degree of freedom, thus generating torsional force during jumper installation, leading to loosening of the wire clamp over time.

Description

Technical Field

[0001] The invention relates to the technical field of power distribution hardware, in particular to a jumper suspension clamp. Background Art

[0002] Suspension clamps are commonly used in fixed products. Now they retain the U-bolt style (usually called boat-shaped clamps). They are composed of a bracket U-bolt, a clamp hull made of forgeable cast iron, and a pressure plate. The other is a pre-twisted suspension clamp. Suspension clamps are used to fix the conductor to the insulator string of a straight pole tower, or to suspend the lightning arrester on a straight pole tower. They can also be used to support the transposed conductor on the transposed pole tower and fix the jumper of the tension angle pole tower.

[0003] In the prior art, the jumper suspension clamp usually uses two nuts installed on a U-bolt to cooperate with the clamp body to tighten the wire pressing block, which is very inconvenient to operate and easy to loosen; at the same time, the traditional jumper suspension clamp can usually rotate in one degree of freedom, so when the jumper is installed, a torsional force is usually generated on the suspension clamp, which will cause the jumper suspension clamp to loosen after a long time. Therefore, we propose a jumper suspension clamp. Summary of the invention

[0004] In order to solve the problem that the jumper suspension clamp usually uses two nuts installed on a U-bolt to cooperate with the clamp body to tighten the wire pressing block, the operation is very inconvenient and easy to loosen; at the same time, the traditional jumper suspension clamp can usually rotate in one degree of freedom, so when the jumper is installed, a torsional force is usually generated on the suspension clamp, which will cause the jumper suspension clamp to loosen after a long time. The purpose of the present invention is to provide a jumper suspension clamp.

[0006] The connection block has a first groove at the bottom and a second groove at the top;

[0007] The wire pressing mechanism comprises a fixing plate fixedly arranged on the side wall of the connecting block, a clamping bolt is threaded vertically downwardly through the base surface of the fixing plate, and the bottom of the clamping bolt is rotatably connected to the wire pressing block;

[0008] The freedom connection member comprises a connection shaft, two ends of the connection shaft are rotatably connected to two mounting blocks, and the side walls of the mounting blocks are provided with pin holes.

[0009] Preferably, the inner wall of the first groove is slidably connected to the inner walls of the two mounting grooves, a screw rod is passed through the side wall of the mounting groove, and the screw rod passes through the side wall of the connecting block, and a nut is installed on the screw rod for fixing the connecting block and the wire trough.

[0010] Preferably, a pin is rotatably inserted into the pin hole on one of the mounting blocks, and the pin is fixedly arranged on the inner wall of the second groove.

[0011] Preferably, the side wall of the wire pressing block is slidably connected to the side wall of the connecting block and the inner wall of the wire groove.

[0012] Preferably, the bottom of the wire pressing block is provided with an upwardly concave arc-shaped groove, and the inner wall is provided with a damping device.

[0013] Preferably, the bottom of the wire trough is an arc-shaped groove, and the inner wall is a damping device.

[0014] Compared with the prior art, the present invention achieves the following beneficial effects: inserting the first groove at the bottom of the connecting block into the mounting groove, then using a screw rod and a nut to fix the wire groove and the mounting groove, and using a free pin to connect the degree-of-freedom connector and the connecting block, so that assembly is very convenient; placing the jumper cable in the wire groove, and located below the wire pressing block, rotating the wire pressing block of the clamping bolt downward, and clamping the cable, the jumper connection operation is very convenient; since the two mounting blocks can rotate on the connecting shaft, and the mounting blocks can rotate on the inner wall of the second groove with the pin as the center, the pin hole in the upper mounting block can also be used to install the pin for installing the jumper suspension clamp, so that the jumper suspension clamp has the characteristics of multi-degree-of-freedom rotation.
