Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding of the skilled person.

As shown in fig. 1-3, the movable beam for supporting the generator stator shed roof comprises two bearing beams 1, a plurality of connecting plates 2, a head plate 3, a separation plate 4, a roller assembly 5 and bolt holes 6. Two spandrel girders 1 are fixedly connected through a plurality of connecting plates 2, and the bottom of the spandrel girder 1 is provided with a roller assembly 5. The end plates 3 are positioned at two ends of the bearing beam 1 and fixedly connected with the bearing beam 1, and two bolt holes 6 are formed in the end plates 3. The isolation plate 4 is composed of two L-shaped plates connected back to back, is positioned in the middle of the tops of the two bearing beams 1, and is fixedly connected with the upper surfaces of the connecting plates 2.

The spandrel girder 1 is made by the rectangle steel pipe, and connecting plate 2 is the angle steel, and end board 3 is the steel sheet, and division board 4 is made by two angle steels that lead to the length back to back welding. The main body bearing structure is two parallel bearing beams 1, the total length of the bearing beams 1 can be determined according to the size of the stator shed, and the structural form of the utility model is determined according to the total length and the stress condition of the bearing beams 1. Two parallel spandrel girders 1 are welded and connected through a connecting plate 2 to form a main body bearing structure, and the bearing requirement is met. Two end plates 3 are respectively welded at two ends of the bearing beam 1, two bolt holes 6 are drilled in the end plates 3, and when the stator shed upright post fixing device is used, the end plates 3 are fixedly connected with the stator shed upright post through bolts. The bottom of two parallel bearing beams 1 is provided with 4 roller assemblies 5, and each roller assembly 5 consists of a high-strength nylon wheel and a roller bracket. The roller wheel component 5 is connected with the bearing beam 1 by spot welding, so that convenience, flexibility and labor saving can be ensured during movement. The middle position of the top of the bearing beam 1 is welded with the isolation plate 4, so that the top cover is supported, the split top cover is isolated, and the requirement that the top cover can be detached at any time before the stator is hoisted is met. The bracket can be arranged on a channel steel track of a bracket of a stand column of the stator working shed according to design requirements, and when a top cover is not used, the bracket is pushed to one side of the stator working shed along the channel steel track to be placed; when the top cover of the stator working shed is closed, the stator working shed is arranged at a designed position and fixed with the bracket by using bolts, so that the stator working shed plays a role in supporting the top cover.
