Description

Emergency repair tower pulling suspension connection frame

technical field

The utility model relates to the field of electric equipment, in particular to a pulling suspension connection frame of a repair tower.

Background technique

The existing power transmission towers are high in height and large in span, and wind cables need to be installed on the towers during installation to fix the tower body to prevent the tower from overturning and collapsing in severe weather conditions such as strong winds. . The existing wind cable fixing method is to set some connecting ear seats on the tower body, and connect the wind cable and the connecting ear seats to the ground through ground anchors. In this fixing method, the connecting ear seats are separately fixed on the tower, mutually There is no cooperation between them. Once a certain wind cable becomes loose, there will be serious safety hazards in the tower. At the same time, the installation of the separately provided connecting lugs is more time-consuming and laborious, which affects work efficiency, especially when urgently repairing the power transmission tower.

The emergency repair tower is a special tower used for temporarily restoring power supply after a tower collapse accident occurs on a transmission line. The quick repair tower is a standard section structure connected by bolts. After the standard sections are connected into an integral structure, it is often necessary to install some other structures on the overall structure, and these structures need to be installed using the threaded holes connected by the standard intersections. , If the threaded holes between the wind cable and the standard section are fixed, the pre-tightening force of the bolts will be insufficient when the standard section is connected.

Utility model content

The utility model provides a pulling and hanging connection frame of a repair tower, aiming at providing a pulling and hanging connecting frame of a repair tower with a more stable fixed wind cable.

The utility model is achieved in that:

A pulling and hanging connection frame for emergency repair towers, comprising a rectangular frame composed of four frames that are sequentially fixed and connected, outer ear seats are arranged on the outer side of the rectangular frame, ear holes are provided on the outer ear seats, and the rectangular frame is also provided with a Fixtures within a rectangular frame.

The existing repair tower wind cables are directly fixed by the connection holes between the standard sections of the repair tower. On the one hand, this operation is not good for the connection and fixation between the standard sections, and it is easy to cause insufficient pre-tightening force between the standard sections; On the other hand, emergency repair towers are generally very high, and they are mostly installed by hoisting. In order to fix the wind cable to the connection hole of the standard section, the bolts connecting the two standard sections need to be removed. It is very dangerous to operate at a high altitude. Especially in severe weather such as strong winds, the standard joint with bolts removed is prone to shaking, and even collapses in severe cases.
