A coupling unit configured to couple a rotatable thread engagement device of a bolt elongation tool for elongating a bolt of a flange connection with the bolt, wherein the bolt elongation tool includes the thread engagement device and an expansion device connected to the thread engagement device, where the coupling unit includes a lowering unit configured to lower the thread engagement device onto the bolt and towards the flange connection, and a rotation unit configured to rotate the thread engagement device when the thread engagement device is lowered, with a rotational speed corresponding to a thread feed of the bolt.

Coupling unit for coupling a rotatable thread engagement means of a bolt elongation tool for elongating a bolt of a flange connection with the bolt

System for supplying hydraulic pressure to a bolt elongation tool, comprising the bolt elongation tool with at least one pressure chamber and a tool piston, a hydraulic medium supply system and a hydraulic actuator with an actuator cylinder housing an actuator piston. The actuator cylinder is attached to the at least one pressure chamber, wherein the hydraulic actuator is an electro-hydraulic actuator comprising an electric motor built to generate the power of the electro-hydraulic actuator, and wherein the actuator piston is built to supply, with one stroke of an actuator stroke height of the actuator piston, at least the amount of hydraulic pressure that is needed to move the tool piston for the amount of one tool stroke height of the tool piston.

System for supplying hydraulic pressure to a bolt elongation tool

Robot () to tighten a series of nuts () pre-screwed on bolts () arranged in a curved flange connection (), which bolts () project from the nuts () pre-screwed in substantially a nut plane () by a projection length (), which robot () comprises a drive to move the robot () along the curved flange connection () and a tool () to tighten the nuts () with a predefined torque both connected to a support platform (), characterized in that the tool () is built to screw a tension nut () onto the bolt () to elongate the bolt () and to tighten the pre-screwed nut () with a predefined torque with a tightening wheel (), which robot () comprises positioning means to substantially align the axis () of the tension nut () with the axis () of the bolt () by lowering the tool () onto the bolt () in order to screw the tension nut () onto the bolt ().

Robot with positioning means to move a tool along a flange connection

Robot () to move a support platform () along a series of nuts () pre-screwed on bolts () arranged in a linear or in particular curved flange connection (). The bolts () project from the nuts () pre-screwed in substantially a nut plane () by a projection length (). The robot () comprises a drive to move the robot () along the curved flange connection (). The drive comprises at least one drive element () and holding means () both connected to the support platform (), wherein the holding means () comprise at least one pair of guiding rails () connected to the support platform () in a distance from each other of more than the diameter (D) of the bolts () and less than the width across flat (AF) of the nuts () and projecting more than the projection length () from the support platform ().

Robot to move a support platform along a flange connection

A robot to bolt down a series of nut bolts in a joint circular flange connection of a wind turbine, which robot comprises at least two wheels and a drive to transport the robot along the series of nut bolts and a tool to bolt down a nut bolt with a predefined torque and a position sensor to position the tool above the nut bolt to be bolted down and a robot control system to control the tightening process and document parameters relevant for the stability of each bolted down nut bolt.
