Problems solved by technology

When the tower frame includes multi-section towers, it is necessary to put forward higher precision requirements for the accuracy of the flange mating surface (flatness and perpendicularity to the center line); at the same time, when the height of the tower frame is high, As the diameter of the tower increases, the mating surface of the corresponding flange also needs to increase; this will greatly increase the processing cost of the flange, and the processing cycle will also be extended, which will greatly increase the manufacturing cost of the tower frame

Embodiment Construction

[0028] The technical solution provided by the present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be regarded as limiting the technical content disclosed in the present invention.

[0029] It should be explained that the tower frame generally includes multi-section towers. In order to save space, this document only specifically describes the connection structure of the two-section towers, and does not describe the connection structure of each tower separately; The connection structure can be connected in the same way.

[0030] In this document, the orientation words "outside" and "inside" are relative to the centerline of the tower frame, the position close to the centerline is "inside", and the position away from the centerline is "outside".

[0031] Please refer to Figure 2 to Figure 5 , figure 2 It is a docking diagram of two towers in the tower ...

Abstract

The invention discloses a tower drum frame, which comprises at least two sections of tower drums that are connected in sequence in an upper-lower direction. In the tower drums, the outer circumference of an inner connecting end of the first tower drum props against the inner circumference of an outer connecting end of the second tower drum; the inner connecting end of the first tower drum is provided with a plurality of inner connecting holes penetrating through the drum wall of the first tower drum, and the outer connecting end of the second tower drum is provided with a plurality of outer connecting holes penetrating through the drum wall of the second tower drum; the tower drum frame further comprises a plurality of connecting assemblies, wherein each connecting assembly comprises a connecting rod and two fastening components; each connecting rod passes through one inner connecting hole and one outer connecting hole; the two fastening components of each connecting assembly are respectively connected with two ends of each connecting rod and respectively supported on the inner circumference surface of the inner connecting end of the first tower drum and the outer circumference of the outer connecting end of the second tower drum. The tower drum frame disclosed by the invention has lower manufacturing cost and corresponding strength.

Description

technical field [0001] The invention relates to a tower tube technology, in particular to a tower tube frame. Background technique [0002] The tower frame is a very common mechanism currently used, such as wind power generation systems, usually using the tower frame to support the wind blades at a predetermined height to absorb wind energy; the storage bin in the concrete mixing plant usually also uses the tower frame structure to store materials ,wait. The tower frame generally includes multi-section tower tubes, and the multi-section tower tubes are sequentially connected in the up and down direction to form the tower tube frame. [0003] At present, the towers are usually connected by a flange structure. Such as figure 1 As shown, this figure shows a schematic diagram of the connection structure between the upper tower and the lower tower in the prior art. The lower part of the upper tower 1 forms a flange 11 protruding outwards or inwards, and the flange 11 is provi...
