Integral installation structure and method of a tower inner platform

Abstract

The invention discloses an integral installation structure and method for an inner platform of a tower. The structure includes a circular frame of the inner platform, a supporting leg structure and an inner platform truss, the inner platform truss is connected with the inner platform circular frame, and the supporting leg structure is connected with the inner platform. The circular frame is detachably connected, and an integral mounting base is set under the circular frame of the inner platform. The integral mounting base includes a base frame, and a liftable support leg is set on the base frame, and the top of the liftable support leg is connected with the circular frame of the inner platform. ;The integral installation base can be reused, and the cost of long-term use is low; the main structure of the tower and the equipment and accessories on the inner platform can be installed at the same time, which greatly reduces the amount of on-site work and work time. The assembly method of the tower platform, the installation process proposed by the invention can shorten the assembly time of the bottom section to less than ten days; in addition, because the welding workload of the inner platform, weldments and the main body is reduced, the unit cost of the tower is also reduced, saving costs .

Description

technical field [0001] The invention belongs to the field of the inner platform structure of the tower frame of the wind power generating set, and in particular relates to an integral installation structure and method of the inner platform of the tower frame. Background technique [0002] Wind power towers are generally connected by three to four sections, and the bottom section is equipped with platform-mounted electrical cabinets, environmental control equipment, fire-fighting equipment, electrical bridges and other equipment and accessories. In a common design, the platform is generally fixed on the tower wall through elastic supports, and the elastic supports need to be drilled in the tower wall and fixed by welding. [0003] Generally speaking, when the tower is manufactured, the main body is first rolled and welded; then holes are opened on the tower wall, and multiple elastic supports are welded and installed; then the inner platform is installed and fixed on the elas...

Problems solved by technology

[0004] In addition, when welding accessories such as ladders and electrical bridges, due to the large number, the workload of the on-site workers is also very large, which also increases the process cost of the unit cost

Therefore, in the process of purchasing the tower, the owner also found that the cost cannot be evaluated only by the weight of the tower, but also by the complexity of the process and the manufacturing cost per unit weight.
