Problems solved by technology

[0003] 1) There is no special lifting tool, and the lifting is mainly carried out by self-made tools with complex structures, which are costly and not easy to carry;
[0004] 2) The lifting tool has poor stability and requires the cooperation of other equipment. It is prone to accidental drop during use, and the safety is low.

Embodiment 2

[0044] The difference between this embodiment and embodiment 1 is as follows:

[0045] Such as figure 2 As shown, the tool body includes two second L-shaped plates 7 arranged at intervals of a set distance, the opening 6 is formed between the two second L-shaped plates 7, and the two second L-shaped plates 7 are realized by the supporting plate 5 connection, the two second L-shaped plates and the support plate 5 form the groove, the second L-shaped plate 7 has the connection hole 1, the support plate 5 is located at the bottom of the second L-shaped plate 7, and the second L-shaped plate 7 is also connected. The second L-shaped plate 7 is connected to the cross arm through the connection hole 1, the tool body is supported from the middle phase wire through the opening, the middle phase wire is lifted to the cross arm, and the second L-shaped plate is connected to the cross arm through bolts. The cross-arm is connected, and the cross-arm is cut off from the opening 6, so that...

Abstract

The invention discloses a middle-phase wire lifting tool and method in tower upgrading and reconstruction, which solves a problem that it is difficult to lift and reconstruct middle-phase wires in cement tower reconstruction in the prior art, and has the beneficial effects of simple structure, convenient carrying, ability of efficiently completing the lifting of the middle-phase wires. The schemeis as follows: the middle-phase wire lifting tool used in tower upgrading and reconstruction comprises a tool body, the tool body is provided with a groove used for accommodating the middle-phase wire, the tool body is provided with an opening, and the tool body is provided with a connecting hole so as to connect the tool body and a tower cross arm.

Description

technical field [0001] The invention relates to the transformation of pole towers, in particular to a lifting tool and method for medium-phase conductors used in the transformation of pole towers. Background technique [0002] The current cement linear pole tower has been put into use for a long time. At that time, the design standard was low, and the distance between the wire and the ground was relatively short. In order to adapt to the development of the economy and society, the upgrading and reconstruction project of the linear cement tower is imminent. At this stage, more stable and complete angle steel towers are generally used to replace the cement towers. During the transformation and upgrading process, the conductors on both sides are easy to extract, and the middle-phase conductors are located under the cross-arm between the two cement towers, while the middle-phase conductors Lifting is the key to the work and restricts the progress of the whole project. The exist...
