Description

Technical Field

[0001] The utility model relates to the technical field of wind power tower manufacturing, in particular to a rotating lifting man-carrying device. Background Art

[0002] In the manufacture of wind power towers, the tower axis must be placed in a horizontal state, and the flange flatness and inclination of the two end faces of the single-section tower must be measured. The tower cannot be rotated or moved during the measurement process. The flange diameter varies from 3m to 5m. In addition to the height of the supporting trolley, the highest point of the flange is nearly 6m from the ground. The measuring instrument is a laser leveler, which consists of two parts. The laser transmitter and receiver can be fixed at a certain place on the flange end face and do not need to be moved after alignment. The other part of the target needs to be manually moved on the arc of the flange end face with an arc length of 300mm to 500mm, and then read and record them respectively. The entire detection process requires the cooperation of two people. It is essential to send personnel to a platform or ladder device about 5m above the ground.

[0003] At present, the manufacturing of wind power towers is required to carry out this inspection work without exception. The traditional method is to set up a wooden ladder, fix the wooden ladder, and measure up and down by the wooden ladder. For a complete measurement, the wooden ladder needs to be moved many times, which is troublesome and inefficient; or a scaffolding is set up on the flange end face, and its width and height must fully cover the circumference of the flange to be measured. The area size and weight of the scaffolding platform are large, inconvenient to move, difficult to set up, and costly; or a hydraulic lift is used to achieve vertical lifting action, but the horizontal movement range is limited. Due to the limitation of the platform area, the hydraulic lift may even need to be moved many times, which is costly and not conducive to energy saving and environmental protection.
