Problems solved by technology

In order to meet different construction site conditions, the height of the power tower is uneven. In order to ensure the stability of the power tower, a waist ring device is needed. The waist ring device of the power tower currently in use is in contact with the main chord of the standard section. It is a roller assembly, which is fixed on the waist ring device by welding, and disassembly and maintenance are time-consuming and laborious
[0003] The existing technology has the following problems: 1. In the existing waist ring device, the roller assembly is in contact with the main chord of the tower body to ensure that the power tower rises steadily during the jacking process. However, the roller assembly and the waist ring are fixed by welding. , time-consuming maintenance and replacement
2. In the process of installing and disassembling the waist ring, workers need to hold the waist ring for operation. The operation process is time-consuming and laborious, and there are potential safety hazards

Embodiment 1

[0031] like Figure 1-7 As shown, a waist ring device 100 includes two door-shaped waist ring half-frames 110, 120 connected with each other and having the same structure and four waist ring hoop devices 130. Taking the waist ring half-frame 110 as an example, the waist ring half-frame 110 includes a waist ring semi-frame body 111, four friction plate bottom plates 112, four friction plates 113 (in order to illustrate the position of the friction bottom plate, image 3 Not drawn in), two main backguy panels 114, four anti-new backguy panels 115.

[0032] The two sections of the waist ring half frame body 110 are fixedly connected with flange plates 116, and the two waist ring half frames with the same structure are overlaid on the standard joints, and the flange plates of the corresponding sections are connected and fixed by bolt assemblies to form a The waist ring device is described to ensure that the waist ring device is firm and reliable, and it is convenient to disassemb...

Abstract

The invention discloses a girdle ring device, which comprises two mutually-connected n-shaped girdle ring semi-frames. Each girdle ring semi-frame comprises a girdle ring semi-frame body, friction sheet bottom plates, friction sheets and a stay wire plate; frame main bodies on the inner sides of the two corners of each girdle ring semi-frame body are each fixedly provided with the corresponding friction sheet bottom plate, and the friction sheets are fixed to the friction sheet bottom plates in a movably connected mode; and the stay wire plates are fixed to the girdle ring semi-frame bodies, and provided with threading holes allowing steel wire ropes to penetrate through. The friction sheets are used for replacing original idler wheel assemblies, thus the more economical and practical effects are achieved, the cost is lowered, and the friction sheets are made of novel synthetic materials, so that it is guaranteed that an electric iron tower stably ascends in the jacking process; and through girdle ring hoops, the girdle ring device is convenient to mount and dismount, transportation, dismounting, mounting and maintenance work is convenient, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to a friction disc waist ring device used for electric holding poles. Background technique [0002] With the development of transmission grid construction, networking projects are increasing, so the number of power towers is increasing. In order to meet different construction site conditions, the height of the power tower is uneven. In order to ensure the stability of the power tower, a waist ring device is needed. The waist ring device of the power tower currently in use is in contact with the main chord of the standard section. It is a roller assembly, which is fixed on the waist ring device by welding, and disassembly and maintenance are time-consuming and laborious. [0003] The existing technology has the following problems: 1. In the existing waist ring device, the roller assembly is in contact with the main chord of the tower body to ensure that the power tower ri...
