Abstract: The present application relates to a tower tube section, a tower frame and a wind power generator set. The tower tube section includes a tower tube section body; a reinforcing assembly including a supporting member connected to the tower tube section body and a plurality of reinforcing cables connected to the supporting member. The plurality of reinforcing cables are arranged at intervals along a circumferential direction of the tower tube section body, and each of the plurality of reinforcing cables extends along an axial direction of the tower tube section body and is apart from a periphery surface of the tower tube section body by a predetermined distance in a radial direction of the tower tube section body. The tower tube section has a strong bearing capacity and low cost, which can meet the power generation benefits of the wind power generator set.

Abstract: The present invention discloses a prestressed-bolted dry-assembled segmental precast hybrid tower with grouting-free, comprising a top steel tower tube, a reverse self-balancing steal-concrete transition section, and a prestressed-bolted dry-assembled segmental precast concrete tower with grouting-free dry fast splicing and a gear reinforced wind turbine foundation; the steel tower tube, the steel-concrete transition section, the concrete tower tube and the hollow wind turbine foundation are integrally connected from top to bottom through a prestressed steel strand system to improve the overall bending resistance of the tower; the upper end of the prestressed steel strands is anchored to the steel-concrete transition section, and the lower end is anchored to the bottom face of the wind turbine foundation corbel; the concrete tower tube is composed of a number of segmental tapered precast concrete tower segments, which are grouting free spliced vertically, and the vertical splicing utilizes positioning pins to accurately position the installation position. The prefabricated concrete tower tube segment is formed by a number of circular arc-shaped prefabricated concrete pipe segments with circumferential grouting free dry splicing. The segments are spliced into a whole by prestressed bolts and then installed staggered from top to bottom to enhance the shear resistance.

Abstract: A device for tightening a screw connection on a flange connection is provided with a tool carrier movable along the flange connection and provided with a traction drive. A tool is arranged on the tool carrier for tightening the screw connection and rotating the nut relative to the flange connection. A control unit is provided for moving the tool carrier in longitudinal direction of the tool carrier into a working position by traction drive control signals. In the working position, the tool is opposite the screw connection to be tightened. The control unit performs, by tool control signals, tightening of the screw connection and rotating of the nut. The control unit has a travel control module with travel controller for moving the tool carrier into the working position. The travel controller stops the traction drive after a predefined travel length has been reached that is a target variable.

Abstract: A method of modular pole construction an elongate modular pole structure is disclosed. A first step of the method involves providing hollow pole section modules, each module having an elongated structure with a base end and an opposed tip end. The modules are stacked to form an elongated modular pole structure of a selected length by mating the tip end of a base module with the base end of an additional module. One or more than one of the modules forming the elongated modular pole structure comprise a composite material having fire resistant properties.
