Description

Transmission line iron tower tilt adjustment lifting device

technical field

The utility model relates to a lifting device for adjusting the inclination of an iron tower of an overhead transmission line.

Background technique

Transmission lines are exposed to barren mountains all year round. Affected by factors such as harsh weather conditions and geological conditions, as the operation time gradually increases, the iron tower will tilt to varying degrees. Force changes will have a certain impact on the safe and stable operation of the line, and the direct cost of replacing a tower is between 200,000 and 300,000. Therefore, it is particularly necessary to study a device that can lift the tower with electricity for tilt adjustment.

Contents of the invention

The utility model provides an inclination adjustment and lifting device for an iron tower of a transmission line, which solves the difficult problem of lifting and adjusting the iron tower of the transmission line after the inclination occurs.

The utility model solves the above technical problems through the following technical solutions:

A transmission line iron tower tilt adjustment and lifting device, comprising a concrete base, a transmission line iron tower foot plate and a transmission line iron tower foot leg are arranged on the concrete base, and an outer clamping plate is fixedly arranged on the outer side of the power transmission line iron tower foot leg. The inner clamping plate is fixedly installed on the inner side of the leg of the line iron tower, and the horizontal outer cross arm is fixedly welded on the outer clamping plate, and the horizontal inner cross arm is fixedly welded on the inner clamping plate, and is installed between the concrete base and the horizontal outer cross arm. There is an outer jack, an inner jack is arranged between the concrete base and the horizontal inner cross arm, and an adjusting gasket is movably arranged between the foot plate of the transmission line iron tower and the concrete base.

The legs of the iron tower of the transmission line and the outer clamping plate are fixedly clamped together by fixing bolts.

The utility model has the advantages of simple structure and easy realization, and is especially suitable for use on construction sites.
