Problems solved by technology

In the case of installations on land, the size of the crane makes it necessary to form a network of roads with sufficient stability to be able to access each location, which further increases the cost of installation

Embodiment Construction

[0024] For a better understanding of the present invention, the lifting system of the telescoping structure will now be described on the basis of diagrams.

[0025] The structure consists of a telescopic tower 1 consisting of a body 2 of four sections having an octagonal shape. Each section of the body in the tower has a plurality of holes 7 on both sides of each side.

[0026] The lifting system has eight bases 3 each supporting its respective hydraulic cylinder 4 vertically and laterally through a path. Each hydraulic cylinder 4 in turn supports its respective fitting 5 connected to four pins 6 perpendicular to the wall of the tower. A base 3 of relative shape is fitted to the outside of the outermost body of the structure and is bolted into said body 2 . To lift the main body 2, four telescopic hydraulic cylinders 4 are used, which are located in successively alternating positions (we may call them A positions). When the telescoping cylinder 4 in the "A position" is clos...

Abstract

The invention relates to a telescopic structure formed by multiple bodies that are erected using a hoisting system comprising: a plurality of base parts (3) that can be screw-coupled to the outermost body (2) of the telescopic structure (1); vertical telescopic hydraulic cylinders (4) supported by the base parts (3), with one cylinder (4) being located on each base part (3), whereby said cylinders can move towards or away from the structure (1) along tracks; and parts (5) connected to through elements (6) perpendicular to the wall of the structure, said parts being located on the cylinders (4), such that, when the cylinders move towards the structure, the through elements are inserted into corresponding holes (7) in the body in order for same to be hoisted, and, as the cylinder is raised, the corresponding body is hoisted.

Description

technical field [0001] The present invention relates to a lifting system of a telescoping structure of large size, which can be used as a support or many other uses for a wind turbine, especially a wind turbine located at sea, which needs to be lifted to a level where it can be used for production height, therefore, the structure had to be raised. Background technique [0002] Existing lifting systems for telescoping structures are based in the case of offshore installations on the use of floating cranes, which are as costly on land as at sea, and also have the added inconvenience of requiring Only in a calm state can it perform its functions normally. If we consider that the choice of site is based on the frequency and strength of the wind, the number of days that the equipment cannot be used in these environments increases the installation expenditure of the tower and wind turbine part. In the case of installations on land, the size of the crane makes it necessary to cre...
