Description

Technical Field

[0001] The utility model relates to the technical field of anti-deformation tooling for a tower flange of a wind turbine generator set, in particular to a simple anti-deformation tooling for a tower flange of a wind turbine generator set. Background Art

[0002] Due to the large size and weight of the tower, the deformation of the tower needs to be strictly controlled during site stacking and long-distance transportation to avoid on-site installation problems caused by tower deformation. In order to prevent further deformation, it is necessary to use corresponding fixed anti-deformation devices to prevent tower deformation.

[0003] However, the traditional tower Pozigzag support used in the prior art prevents the tower flange from deforming by the friction of bolts. However, the tooling may lose its ability to prevent deformation due to workers not tightening the torque or vibration during tower transportation. Alternatively, a support with a driving device is used. Although the radius of the support can be flexibly adjusted, the overall device is relatively complicated, resulting in inconvenience in installation and transportation. Utility Model Content

[0004] The utility model aims to solve the deficiencies in the prior art and provides a simple tooling for preventing the deformation of the tower flange of a wind turbine set. The flange is pulled by a manual hoist. After the ovality of the flange meets the requirements, the wire rope is tensioned by a screw tensioner to achieve the flange support effect.

[0005] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a simple anti-deformation tool for the tower flange of a wind turbine generator set, comprising a flange support assembly and a pull plate assembly, wherein the flange support assembly has multiple groups arranged circumferentially along the outer circumference of the pull plate assembly; wherein the flange support assembly comprises a wire rope, a screw tensioner, a pull rod assembly and a U-shaped turnbuckle; one end of the wire rope is connected to the pull rod assembly, and the other end of the wire rope passes through the pull plate assembly and is connected to one end of the screw tensioner through a U-shaped turnbuckle, and the other end of the screw tensioner is connected to the pull rod assembly through another U-shaped turnbuckle.

[0006] Furthermore, it also includes a hand chain hoist; the hand chain hoist is connected to the pull rod assembly.

[0007] Furthermore, the pull plate assembly includes a circular ring plate and a cross bar, and the circular ring plate has two pieces connected together by a plurality of cross bars.

[0008] Furthermore, the number of the cross bars is the same as the number of the flange support assemblies.

[0009] Furthermore, one end of the steel wire rope is connected to the pull rod assembly, and the other end of the steel wire rope passes through the pull plate assembly and passes around its cross bar and is connected to one end of the screw tensioner through a U-shaped turnbuckle.

[0010] Furthermore, the tie rod assembly includes a plurality of tie rods arranged in parallel.

[0011] Furthermore, there are two U-shaped turnbuckles, which include a U-shaped frame and a connecting rod. The connecting rod is installed between the two open ends of the U-shaped frame, and the closed end of the U-shaped frame is provided with a screw hole for the screw to pass through; the connecting rod of one U-shaped turnbuckle is connected to the wire rope, and the other U-shaped turnbuckle is inserted into the pull rod assembly to form a detachable connection with the pull rod assembly.

[0012] Furthermore, the screw tensioner includes a tensioning frame and a screw, and screw holes are opened at both ends of the tensioning frame. After the screw passes through the screw hole of the U-shaped turnbuckle and the screw hole of the tensioning frame in sequence, the screw forms a movable connection with the tensioning frame and the U-shaped turnbuckle.

[0013] Furthermore, there are 8 groups of flange support assemblies.

[0014] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0015] The utility model pulls the pull rod assembly through the hand winch to drive the wire rope to be tensioned, so as to achieve the function of supporting the tower flange, and can make slight adjustments to the tension of the wire rope through the screw tensioner. It is not only useful for newly produced tower flanges, but also can play a corrective role for tower flanges that have been stored for a period of time and are seriously deformed. At the same time, the utility model can flexibly adjust the radius of the support, and is suitable for tower flanges of different diameters. The tooling is simple and easy to transport and install.
