Hydraulic elevating device for iron tower

Abstract

The invention discloses a hydraulic elevating device for an iron tower. The hydraulic elevating device comprises two base brackets. An extending-and-contracting bracket is mounted in each base bracketin a sleeved manner. Pin holes are formed in the base brackets and the extending-and-contracting brackets in a spaced manner. A lower support beam is mounted at opposite positions of the base brackets. An upper support beam is mounted at opposite positions of the extending-and-contracting brackets. A first pull plate and a second pull plate are arranged on the upper support beam. A hydraulic jackis arranged on the lower support beam. According to the hydraulic elevating device, by means of the pin holes formed in the extending-and-contracting brackets and the base brackets in the spaced manner, a tower foot can be elevated level by level; the tower foot can be elevated by a large stroke through the small-size hydraulic jack; a small number of tools are used; the operating steps are simple; and maintenance cost of the power transmission iron tower is greatly lowered.

Description

technical field [0001] The invention relates to a maintenance device for a power transmission iron tower, in particular to a hydraulic lifting device for an iron tower. Background technique [0002] Transmission towers are often tilted due to ground subsidence and other reasons. Due to the large size and mass of the tower, it is necessary to use large lifting equipment to straighten it, or use hydraulic equipment to jack up the tower foot. The lifting equipment is all large-scale machinery, and most of the iron towers that have settled are located in the suburbs or mountainous areas. It takes time and effort to dispatch and transfer, and it is even impossible to construct when the site situation is complicated; hydraulic equipment is smaller than lifting equipment, and construction is less difficult, but the hydraulic lifting space is limited. If the inclination angle of the iron tower is large, large hydraulic cylinders are required, and multi-cylinder operations are often ...

Problems solved by technology

The lifting equipment is all large-scale machinery, and most of the iron towers that have settled are located in the suburbs or mountainous areas. It takes time and effort to dispatch and transfer, and it is even impossible to construct when the site situation is complicated; hydraulic equipment is smaller than lifting equipment, and construction is less difficult, but the hydraulic lifting space is limited. If the tilt angle of the iron tower is large, large hydraulic cylinders are required, and multi-cylinder operations are often required, and a large amount of equipment also needs to be carried, which greatly increases the construction cost
