Embodiment Construction

[0020] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0021] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening ele...

Abstract

The invention relates to a temporary cross arm capable of operating in an alive state. The temporary cross arm comprises a lifting sliding tube, a lifting fixing tube, a telescopic sliding tube, a telescopic fixing tube, a first driving device, a second driving device and a controller. The lifting sliding tube slidably sleeves the lifting fixing tube. The telescopic fixing tube is mounted on the lifting sliding tube. The telescopic sliding tube slidably sleeves the telescopic fixing tube. The telescopic sliding tube is provided with a wire clamp. The first driving device is in driving connection with the lifting sliding tube. The second driving device is in driving connection with the telescopic sliding tube. The first driving device and the second driving device are electrically connected with the controller. The temporary cross arm capable of operating in an alive state is easy to install and adjust and high in operation efficiency, and can adjust the height and position of a line wire according to an actual situation so as to prevent damage to line equipment and the line wire due to over traction.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a temporary cross arm capable of live work. Background technique [0002] In order to improve the operational reliability of distribution lines, insulated overhead lines have been widely used in urban distribution networks. Due to tight line corridors, many distribution lines are erected multiple times on the same tower. When the operator performs live work on the line equipment, there is a risk of electric shock due to the short circuit of the air gap. Many jobs involve the replacement of line equipment such as insulators, straight rods and tension rods. Among them, the transfer and temporary fixation of line conductors are the key steps in related work projects. During the operation process, the temporary cross arm is mainly used to support the line conductors. The traditional temporary cross-arm is difficult to install and adjust, the work efficiency is low, it is d...
