Abstract

Provided is a wedge driving jig in which a wire clamping clamp can be easily driven on a steel tower by reducing the weight of the wire clamp attaching / detaching machine and operating a handle of a hydraulic jack.
A light-weight type wire clamp wedge driving jig 1 is provided with a hydraulic pump and a handle on a bottom plate of a frame 3 which is a lattice assembly of four steel rods 7, a clamp mounting ring 4R and a wire mounting ring 4W. Wedge driving jig equipped with a hydraulic jack 5

Description

The present invention relates to a jig for driving a wedge into a core wire of an electric wire inserted into a clamp for temporarily connecting and extending electric wires (stranded wires of 810 mm ² or less) of a transmission line with a wire extension clamp.

Wire extension clamps are used as connection fittings to temporarily connect wires or wires to each other in construction, removal, etc. of overhead power transmission lines, and extend the ends of the cut wires. A hydraulic wire extension clamp attaching / detaching machine has been put into practical use as a wedge pushing jig for inserting a wedge into the core wire of the electric wire clamp and pinching the electric wire accurately after being inserted into the wire clamp.

Technical literature

Registered Utility Model Publication: No. 3147904 (Drawing wire clamp driving jig)

In addition to the hydraulic pump consisting of a handle and a hydraulic cylinder, the existing wire clamp attaching and detaching machine has a bottom plate (for mounting a hydraulic cylinder) and a ring for mounting a clamp on a frame body in which four steel rods are formed in a regular quadrangular pyramid shape. It is configured to be connected to the wedge pusher equipped with the ring for attaching the electric wire with a hose and operated in a batch. However, since the collective weight is heavy, it is not easy to start the operation. Needed more than one person.

Means for solving the idea

In order to solve the above-described problems, in the wedge driving jig of the wire extension clamp according to the present invention, the hydraulic jack is directly operated by the handle without using a heavy hydraulic cylinder and a hydraulic pump with a handle hose. As a result, the jig was lightened (weight: 10 kg or less) and the wedge driving operation was made safe and efficient.

For this reason, in the wedge driving jig for the extension wire clamp of the present invention, a hydraulic jack in which a hydraulic pump and an operation handle are integrated with a hydraulic cylinder is mounted in the frame body, and the wedge is operated easily and simply by operating the handle. Improved to allow driving.

A wedge driving jig (front and side view) of the lightweight wire extension clamp of the present invention. Prefabricated wire clamp detaching machine (front and side views). Wire clamp body (front, sectional view).

As described above, the weight of the existing wire clamp attachment / detachment machine and the operation of the handle of the hydraulic jack are simplified, and the operation of driving the wedge of the wire extension clamp on the steel tower is easily performed.

Embodiments will be described below with reference to the accompanying drawings. FIG. 1 shows a wedge driving jig 1 for a lightweight wire-drawing clamp according to the present invention. A hydraulic pump 5P is attached to a bottom plate of a frame 3 which is a lattice assembly of four steel rods 7, a clamp mounting ring 4R and an electric wire mounting ring 4W. 2 is a wedge driving jig equipped with a hydraulic jack 5 equipped with a handle. FIG. 2 shows the configuration and shape of an existing wire drawing clamp attaching / detaching machine 2, and includes a hydraulic cylinder 5C, a handle 6 and a hose 5H. A wedge pushing device (a device for attaching a hydraulic jack 5 to the frame 3 and driving a wedge by hydraulic operation) used in combination with the pump 5P is shown. FIG. 3 is a diagram showing a shape and a cross section of the wire clamp 4 used when the stranded wires W are temporarily connected to each other.

Claims (1)

In a more linear (wire 810 mm ² or less) ready-extending line clamp disassembling machine using a cross when temporary connection, a handle, a pump, Ho - Hydraulic ho a press-in machine hydraulic pump and with a hydraulic cylinder with scan - scan Because the weight of the jig that drives the wedge into the wire clamp by operating it integrally is heavy, and the wedge attachment / detachment work on the steel tower is not performed smoothly, making the jig lightweight and compact. For the purpose, a lightweight jack that features a hydraulic jack in which a hydraulic pump and a handle are integrated (provided) in a hydraulic cylinder, and that simplifies the jig and makes the wedge driving work more efficient. Clamp wedge driving jig.
