Abstract

The utility model relates to a rapid rounding device for a wind power generation tower cylinder joint, which is characterized in that four long steel tube supports and four adjusting supports are respectively provided with a groove at the center of one end, and the outer edge of a central circular plate already divided into eight equal pieces is inserted into the grooves and welded, and each adjusting support consists of a short steel tube support, a fixing nut and an adjusting screw rod which are assembled together and welded. The utility model, which has the advantages of compact structure, convenient fabrication and convenient operation, can rapidly round the end of the butt cylinder joint, thus increasing the butting efficiency.

Description

A kind of wind power tower shell ring holds round device fast

One, technical field:

The utility model relates to a kind of wind power tower shell ring and holds round device fast, belongs to the technological equipment field.

Two, background technology:

At present the pylon in the Large-scale Wind Turbines generally adopts sledgehammer, tiltedly instrument such as son, fixed block and electric welding machine equipment do not have that misalignment is powerful to be docked, because two shell rings of butt joint difficulty when circle circle, campus reaches desirable circularity mutually, must have ovality in various degree.

Shortcoming: 1, butt joint efficient is low, and speed is slow;

When 2, docking because of two shell rings, fixed block will often be welded on two shell ring ends, and the butt joint welding needs fixed block is laid behind the location, descends the butt joint at position again, therefore, damages two shell ring circumferential welds surface quality on every side.

Three, summary of the invention:

Goal of the invention of the present utility model: provide a kind of wind power tower shell ring to hold round device fast, the end of butt joint shell ring can be held round fast, improve the butt joint efficient of two shell rings, do not damage the shell ring surface quality of butt joint circumferential weld both sides.

Adopt following technical scheme for reaching innovation and creation purpose the utility model:

A kind of wind power tower shell ring holds round device fast, it is characterized in that: it is to support (3) difference center grooved at one end with 4 steel pipe long supports (2) and 4 adjustment, insert welding from the outer rim of the center plectane (1) of having divided equally 8 equal portions and fixedly form, adjust and support (3) by the short supports＜3-1 of steel pipe 〉, hold-down nut＜3-2, adjustment screw rod＜3-3 assemble and be welded.

The use of this device be with the shell ring end of two butt joints of needs all earlier after holding round on the ground handling platform, with the 2nd shell ring with the driving lifting after, fall into first shell ring upper end, thereby realize rapid abutting joint.

3, technical characterstic of the present utility model and result of use:

1), the end of butt joint shell ring can be held round fast, be two shell rings fast group to laying a solid foundation;

2), improve butt joint efficient;

3), do not damage the shell ring surface quality of butt joint circumferential weld both sides;

4), the utility model compact conformation, be convenient to make, easy to operate, result of use is good, can reach the purpose of innovation and creation fully.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a horizontal cross of the present utility model;

Fig. 3 is a use schematic diagram of the present utility model;

Among the figure: 1-center plectane, the long support of 2-steel pipe, 3-adjusts support, and the 3-1-steel pipe is short to be supported, the 3-2-hold-down nut, 3-3-adjusts screw rod.

Five, the specific embodiment:

The specific embodiment of the present utility model is as follows: center plectane (1) is by steel plate numerical control oxygen-acetylene cutting, short support (3-1) of steel pipe long support (2) and steel pipe adopts seamless steel pipe, one end mills out elongated slot on milling machine, insert solid welding from garden, center plate (1) outer rim by 8 equal portions, adjust to support the hold-down nut (3-2) in (3) and adjust screw rod (3-3) being carbon steel material, and then pack into and can use in the hold-down nut (3-2) adjusting screw rod (3-3) after hold-down nut (3-2) and the short support of steel pipe (3-1) solid welding again by figure processing.

Using method of the present utility model: 1., go out by the outer circumference of support shell ring end with the steel tape actual measurement; 2., calculate by the outside diameter size of support shell ring according to outer circumference; 3., will hold round device is placed on by support shell ring inner end; 4., adopt the cross balanced method to adjust screw rod and reach the shell ring outside dimension for extremely with the steel tape measurement with the spanner rotation.To reach the purpose that holds round fast.

Claims

1, a kind of wind power tower shell ring holds round device fast, it is characterized in that: it is to support (3) difference center grooved at one end with 4 steel pipe long supports (2) and 4 adjustment, insert welding from the outer rim of the center plectane (1) of having divided equally 8 equal portions and fixedly form, adjust and support (3) by the short supports＜3-1 of steel pipe 〉, hold-down nut＜3-2, adjustment screw rod＜3-3 assemble and be welded.
