Description

Technical Field

[0001] The invention relates to the field of circulatory Pozidriv stretching tooling applicable to flanges of different specifications, and in particular to a circulatory Pozidriv stretching tooling applicable to flanges of different specifications. Background Art

[0002] The height of a wind turbine tower may reach hundreds of meters. It is not cast in one go, but mostly connected by multiple tower sections. The end of each tower section is equipped with a flange welded to the tower section before hoisting. Due to the existence of ovality, the stability of the tower will be reduced under the action of external forces. The wind tower is a long way from the tower manufacturer to the wind farm site, and the road conditions vary. In many cases, the tower length is nearly thirty meters. During the entire tower transportation process, the tower end flange may be slightly deformed due to force, resulting in excessive flange ovality, which affects the installation during tower hoisting and brings many inconveniences. The flange needs to be corrected, which reduces work efficiency and affects the progress of on-site construction. Therefore, it is necessary to ensure that the tower ovality is not greater than a certain value. In order to prevent the wind turbine tower flange from elliptical deformation and affect the tower installation, 10# channel steel crisscross support is conventionally used for fixing; However, the existing channel steel MIT-shaped support has a bulky structure and, because it is a support component, needs to be processed before being installed as a whole. The installation is difficult and requires three people to work at the same time, which consumes a lot of manpower and material resources. In addition, different tower flanges have different sizes, and one specification of channel steel MIT-shaped support is only suitable for one specification of flange, which is not convenient for disassembly, recycling and reuse. Summary of the invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a recyclable Pozigzag bracing tool suitable for flanges of different specifications, which can solve the technical problems that the existing Pozigzag support in the form of channel steel has a bulky structure and, because it is a support member, it needs to be processed before being installed as a whole, which is difficult to install and requires three people to work at the same time, consuming a lot of manpower and material resources. In addition, the sizes of different tower flanges are different, and one specification of channel steel Pozigzag support is only suitable for flanges of one specification, which is inconvenient to disassemble, recycle and reuse.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a recyclable Pozidriv tensioning tool suitable for flanges of different specifications, comprising a connecting and fixing ring, a side wall of the connecting and fixing ring is provided with a through hole, and a steel rod extends from the inner side of the through hole, the other end of the steel rod is fixedly connected to a fixing plate, a threaded head is provided at one end of the steel rod away from the fixing plate, a groove is provided on the inner side of the fixing plate, a nut is sleeved on the outer side of one end of the threaded head, an arc-shaped socket is provided on the inner side of the groove, and teeth are provided on the inner side wall of the arc-shaped socket, a pushing structure is provided on the other end of the arc-shaped socket, and an internal thread is provided on the inner side wall of the nut.

[0005] As a preferred technical solution of the present invention, the pushing structure includes a damper and a spring, the damper is fixedly connected to one end surface of the arc-shaped holder, and the outer surface of the damper is sleeved with a spring.

[0006] As a preferred technical solution of the present invention, the through holes are equidistantly distributed along the center point of the connecting and fixing ring, and the through holes and the connecting and fixing ring form an integrated structure.

[0007] As a preferred technical solution of the present invention, the steel rods are vertically distributed to the fixing plate, and the steel rods are equidistantly distributed along the center point of the connecting fixing ring.

[0008] As a preferred technical solution of the present invention, the outer diameter size of the thread head is matched with the inner diameter size of the through hole, and the number of the thread heads is consistent with the number of the through holes.

[0009] As a preferred technical solution of the present invention, the nuts are distributed in parallel, and the nuts and the internal threads form an integrated structure.

[0010] As a preferred technical solution of the present invention, the arc-shaped holder is slidably connected to the steel rod through the damper, and the arc-shaped holder is semicircular as a whole.

[0011] As a preferred technical solution of the present invention, the teeth are equidistantly distributed along the center point of the arc-shaped seat.

[0012] Compared with the prior art, the present invention can achieve the following beneficial effects: 1. Combined with the set connection fixing ring, steel plate, fixing plate and nut structures, it can be applied to tower flanges of different specifications and can adjust the size. Only 2-3 sets are needed for one project, which saves materials and costs. The tension strength can be adjusted, which has a good control effect on the flange ovality deformation, avoids the correction of the flange, improves the tower installation efficiency, saves time, and has a light overall structure and low installation difficulty. It can be installed by one person, reducing labor input, saving manpower, reducing the overall welding amount, and is beneficial to environmental protection. It can be disassembled and convenient for recycling; 2. Combined with the damper, spring, arc-shaped holder and other structures, the stability of the connection between the fixing plate and the flange can be improved. When the fixing plate is placed on the bolt hole at the bottom of the flange, the bolt is input into the inner side of the bolt hole. At the same time, the damper and spring will push the arc-shaped holder, so that the teeth set on the inner side of the arc-shaped holder will contact with the bolt, thereby improving the stability of the connection between the fixing plate and the flange.
