High-altitude crimping apparatus of power transmission line

Abstract

The invention relates to a high-altitude crimping apparatus of a power transmission line. The apparatus comprises a hydraulic scissors, a hydraulic wire stripper, and a crimping machine. The crimping machine is on a transverse ladder and can move on the transverse ladder; two ends of the transverse ladder are respectively equipped with a lifting hook and a cross-arm hasp, wherein the lifting hookand the cross-arm hasp are used for supporting and suspending the transverse ladder; the transverse ladder can make rotation relatively to the transverse ladder. An oil pump is arranged at an end of the transverse ladder, wherein the end corresponds to one end that is provided with the cross-arm hasp. According to the invention, the end of the cross-arm hasp is connected with a tower corner iron and the lifting hook is connected with a fixed cable or a wire rope, so that the whole transverse ladder can be installed and fixed in the air; a worker can complete the compression joint work of conducting wires on the transverse ladder, so that a reliable working platform is provided and danger of high-altitude working can be reduced; when the conducting wires can not be bent, the crimping machine can move or make rotation by a mobile frame body and a base plate support of the crimping machine, so that labor intensity of the working people is reduced. Besides, the working efficiency can be improved rapidly. The apparatus has advantages of compact structure and safety and reliability. And the apparatus is also easy to install and use.

Description

technical field [0001] The invention relates to a cable crimping device, in particular to a power transmission line high-altitude crimping device, which belongs to the technical field of cable high-altitude crimping. Background technique [0002] During the construction of transmission lines, when crimping the tension clamps, the second tightening operation method is generally adopted; that is, after the first tightening is in place, personnel mark on the high-altitude conductors, and then loosen the conductors to the ground , Then open and break the wire, strip the wire, crimp the tension clamp, and finally hang the crimped wire. However, with the rapid development of the economy, the line channel is relatively tight. It is often encountered that there are highways, high-speed railways, rivers, etc. under the tension tower, and the conductor cannot be loosened to the ground. That is to say, after the wire is tightened in place, disconnecting the wire, stripping the wire, a...

Problems solved by technology

However, with the rapid development of the economy, the line channel is relatively tight. It is often encountered that there are highways, high-speed railways, rivers, etc. under the tension tower, and the conductor cannot be loosened to the ground. That is to say, after the wire is tightened in place, disconnecting the wire, stripping the wire, and crimping the strain clamp must be completed at a high altitude.

[0003] At present, most of the high-altitude crimping uses personnel to climb to the designated position through porcelain bottle strings or tight wire ropes. There is no equipment to enable personnel to reach the work area safely, and there are hidden dangers in terms of safety.

When hoisting the crimping machine to the working position for crimping, the crimping machine has no fixed position, and the crimping machine cannot rotate freely, and the diameter of the crimped wire is large and cannot be easily bent; this requires The crimping machine can be rotated 360 degrees to fit the angle of the wire

Since the operating mechanism of the original gasoline engine oil pump is set on the cross arm of the iron tower, it will inevitably cause delays in the transmission of passwords between operators, resulting in excessive crimping pressure, etc.

In general, the original high-altitude crimping method will cause inconvenient work activities because the personnel do not have a comfortable working position. In addition, the crimping machine is large in size and heavy in weight, which makes high-altitude crimping time-consuming and laborious, which greatly increases the construction cost.
