Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical equipment, in particular to a turning and reversing method for a lifting and rotating device for wind power tower drum manufacturing. BACKGROUND

[0002] Wind power tower drum manufacturing involves ten processes such as slope cutting, plate rolling, longitudinal seam welding, inspection, accessory welding, surface treatment, corrosion prevention, accessory installation, final inspection, and product delivery. The product internal transportation is always involved in these ten processes. The site of the tower drum manufacturing base is usually temporary. Due to limited space, it is not possible to set up a direct roller track from the corrosion prevention process to the accessory installation process and the finished product process. In order to save rental space, the tower drum transfer track is arranged in a 90° cross shape, which saves rental space, but increases the difficulty of tower drum transportation. If a crown block is used for hoisting and a car is used for transportation, not only the operation space is occupied, the efficiency is low, but also the operation personnel and cost are increased. The currently marketed equipment that can turn and reverse in place has a maximum rotating diameter of 5 meters and a maximum load of about 60 tons, and does not have a lifting device, which cannot be separated from and replaced with a roller track. It cannot meet the requirements of tower drum transportation in terms of size, load and function. In order to save space, improve production efficiency and save cost, a rotating lifting transfer machine with a rotating diameter of 8 meters and a load of more than 130 tons is needed. The transfer machine is a device for realizing the turning and lifting of the tower drum in place, which is installed at the intersection of two tracks on the horizontal plane. The track on the transfer machine platform and the ground track are on the same horizontal plane, and are arranged in a circular pit type to realize the turning and lifting of the tower drum from one process to another process at any time to meet the production needs.
