Tower drum internal integration truss device and installation method thereof

Abstract

The invention discloses a tower drum internal integration truss device. The device is characterized by comprising a truss of a square structure, a cable bridge arranged on the outer side of the truss, a ladder stand arranged on the inner side of the truss, an elevator arranged in the truss and an illuminating system arranged on the outer wall of the truss, wherein the truss is composed of multiple sections of truss bodies, the number of the truss bodies is the same as the number of segments of a tower drum, the height of each section of one truss body is the same as that of the corresponding segment of the tower drum, each upper truss body and the corresponding lower truss body are connected through a guiding device, and each section of each truss body is fixed to the inner wall of the tower drum through a connecting device. The device has the advantages of being reasonable in structural design, quick and convenient to install and high in strength; meanwhile, the cable bridge and the illuminating system are fixed to the outer side of the truss, so that easily damaged parts in the tower drum are gathered within a manipulative range of the center of the truss, follow-up maintenance is facilitated, and maintenance cost is reduced.

Description

technical field [0001] The invention relates to a truss device, in particular to an integrated truss device inside a tower and an installation method thereof, belonging to the field of offshore wind power generation equipment. Background technique [0002] In the wind power industry, ladders, power cable splints or bridges, lighting cable bridges, elevators, etc. are usually designed separately. However, as the diameter of the tower of high-power wind turbines is getting larger and larger (the bottom diameter of the 5MW and 6MW towers is currently 6-7 meters), the number of cables in the tower is increasing, and the width of the cable splint or bridge is also increasing. The larger the distance, the further the distance between some cables and the ladder, making it difficult for maintenance personnel to maintain or repair the cables on the cable splint or bridge on the ladder, which greatly increases the difficulty and cost of follow-up maintenance. Therefore, a new technic...

Problems solved by technology

However, as the diameter of the tower of high-power wind turbines is getting larger and larger (the bottom diameter of the 5MW and 6MW towers is currently 6-7 meters), the number of cables in the tower is increasing, and the width of the cable splint or bridge is also increasing. The larger the distance, the longer the distance between some cables and the ladder, making it difficult for maintenance personnel to maintain or repair the cables on the cable splint or bridge on the ladder, which greatly increases the difficulty and cost of subsequent maintenance
