Description

A wind power foundation ring turning device

technical field

The utility model relates to the field of wind power generation equipment, in particular to a wind power foundation ring turning device.

Background technique

The wind power foundation ring turning device is used as the turning and lifting auxiliary tooling of the wind power foundation ring, which is suitable for the work of turning the wind power foundation ring from the vertical position 90° to the horizontal position or from the horizontal position to the vertical position.

As the bottom support of wind power generation equipment, the structure of the wind power foundation ring is composed of three parts welded from top to bottom: the top machined flange, the cylinder body and the bottom tailor welded flange. Among them, the top machined flange has multiple There are three equally spaced bolt holes, oval holes for interspersed steel bars are distributed on the circumference of the cylinder body at a specific height, and the tailor-welded flange at the bottom generally has three symmetrically distributed bolt holes.

In the welding and manufacturing process of the wind power foundation ring, firstly, the machined flange, cylinder body and tailor-welded flange of the wind power foundation ring are assembled in sequence in a vertical position. Secondly, it is necessary to lift the wind power foundation ring and turn it over 90° to a horizontal position, and place it on the roller frame station to perform two ring seam welding processes. Finally, after the ring seam welding is completed and the weld seam inspection is qualified, the wind power foundation ring is lifted from the horizontal position on the roller frame station and turned 90° to the vertical position, and unloaded to the qualified product stacking area.

The existing overturning device uses ordinary lifting lugs to be installed in the elliptical hole position of the cylinder body. After eccentric lifting, the adjustment of the position and state is realized through the adjustment of the center of gravity of the wind power foundation ring. The disadvantage is that there are safety hazards such as cable-stayed and inclined hanging, and long-term use is easy to damage the crane. The state of the motor is unstable during the hoisting process, relying too much on the operating experience of the hoist, and it is easy to cause unnecessary bumps on the product.

Contents of the invention

The utility model aims at the defects of the prior art: potential safety hazards such as cable-stayed and inclined cranes, long-term use is easy to damage the motor of the crane, the state of the hoisting process is unstable, the operation experience of the hoisting worker is too dependent, and unnecessary bumps are easily caused to the product, etc. Provide a wind power plant that is easy to manufacture and operate, with guaranteed safety of personnel, equipment and products, short hoisting preparation time, stable lifting and turning operations, and no damage to the cylinder or flange of the wind power foundation ring itself during the hoisting process. Base ring flip device.

The technical scheme adopted by the utility model to solve its technical problems is as follows: a wind power foundation ring turning device, which is characterized in that it includes a boom, and the two ends of the boom are respectively provided with a connecting ring and a winch system, The connecting rings are respectively connected with the first machined flange lifting lug and the second machined flange lifting lug through the first and second connecting ropes, and the winch system is connected with the tailor-welded flange lifting lug through the third connecting rope. The first machined flange lug, the second machined flange lug and the tailor-welded flange lug are respectively provided with connecting holes, and a lifting ring is provided in the middle above the boom.

According to the above structure, wherein the tailor welding flange lug is connected to the hoisting system through the pulley block through the third connecting rope.

According to the above structure, the first, second and third connecting ropes are respectively connected to the first machined flange lug, the second machined flange lug, tailor welding through the first, second and third shackles respectively. Flange lug connection.

According to the above structure, preferably, the length of the boom is greater than or equal to the width of the basic ring.

According to the above structure, preferably, the first, second and third connecting ropes are all steel wire ropes.

According to the utility model with the above-mentioned structure, compared with the prior art, its beneficial effects are that the manufacture and operation are simple, the safety of personnel, equipment and products is guaranteed, the lifting preparation time is short, the lifting and turning operation is stable, and during the lifting process It does not cause damage to the cylinder body or the flange itself of the wind power foundation ring.
