Abstract

The invention discloses a horizontal adjustment device of a wind turbine blade mould. The horizontal adjustment device comprises a screw (1), a bearing plate (2), a nut (21) and a supporting leg (3). The invention adopts the technical scheme as follows: for a height adjustment device formed by the screw, the bearing plate with the nut and the supporting leg, the bearing plate is fixedly welded at each supporting point at the lower side of a foundation steel frame of a blade male mould, the supporting leg is supported on the support, when the height adjustment device is used, a high flatness field is not needed, a laser leveling instrument is used for indicating the benchmark, the height of each supporting point of the blade male mould is adjusted by rotating the screw, and then the horizontal form and position of the blade male mould are aligned; and the technical scheme has the advantages of overcoming the problems and defects of long construction period, low efficiency and high cost existing in the prior art, aligning the horizontal form and position of the whole body through point-by-point height adjustment, enabling the manufacture of the wind turbine blade to be free from the dependence on the high flatness field and achieving the purposes of shortening the construction period, improving the efficiency and reducing the cost.

Description

A kind of level(l)ing device of wind-powered blade mold

Technical field

The present invention relates to a kind of apparatus for adjusting position, specifically be meant when making the blade of wind-driven generator, be used to regulate the level(l)ing device of a kind of wind-powered blade mold of finding the horizontal morpheme of blade male die accurately.

Background technology

The blade of wind-driven generator has the member of starching shape in the shape of a spiral of skeleton for the hollow and thin-walled inner support, is called for short wind electricity blade, and the length of wind electricity blade can reach 100 meters; So huge member must be in the wind-powered electricity generation field fabrication, and during making, the compound whole blade former of the type of processing that turns on blade male die is fixed on produced with combination blade goods on the steel keel skeleton with the blade former more earlier; So-called blade male die is a kind of mould that is made up of the different streamlined rib template polyphone of blocks of top profile curve shape gradual change; The assembled on site blade male die; Prior art takes to construct at the wind-powered electricity generation scene the high Pingdu of the concrete greater than the high flatness of a length of blade and width place; To in factory, prefabricated piece assembly unit of blade male die assembly connect into integral body on the ground in high Pingdu field; The shape position error of blade male die depends on the flatness in high Pingdu place, and so broad high Pingdu place is long in time limit, cost is high owing to construct at the wind-powered electricity generation scene, causes the making of wind electricity blade long in time limit, cost is high; Therefore, there are problems and shortcomings long in time limit, that efficient is low, cost is high in prior art.

Summary of the invention

To the problems and shortcomings that above-mentioned prior art exists, the present invention adopts the arrangement for adjusting height that is made up of screw, the loading plate that is provided with nut and feet, loading plate is fixedly welded on each following fulcrum place of the basic steelframe of blade male die; Be supported on ground by feet, during application, only need the simple smooth at the scene smooth that goes out; And need not high Pingdu place; Utilize laser leveler indication benchmark,, find the technical scheme of the horizontal morpheme of blade male die then accurately through the height of each fulcrum of rotary screw adjusting vane formpiston; A kind of level(l)ing device of wind-powered blade mold is provided; Be intended to highly regulate and find the integral level morpheme accurately, make the making of wind electricity blade break away from dependence, the purpose that reach the reduction of erection time, raise the efficiency, reduces cost high Pingdu place through pointwise.

The objective of the invention is to realize like this: a kind of level(l)ing device of wind-powered blade mold, comprise screw, loading plate, nut, feet, wherein: described screw is the outer-hexagonal hook bolt;

Described loading plate is a steel plate triangular in shape; The center of loading plate is provided with a through hole, is fixedly welded with an outer-hexagonal nut above the said through hole and is called nut;

Described feet is for by nut and the circular steel plate that the is called support pad member that constitutes of superimposed fixedly welding up and down;

From top to bottom, screw passes loading plate and screws with said nut slip, and the lower end of screw is fixedly connected with the said nut screwing and the welding on feet top; Loading plate is fixedly welded on each following fulcrum place of the basic steelframe of blade male die.

Operation principle and beneficial effect

During application, be supported on ground, utilize laser leveler indication benchmark, find the integral level morpheme of blade male die through the height of each fulcrum of rotary screw adjusting vane formpiston one by one accurately by the said support pad of feet; Because this device is highly regulated through pointwise and is found the integral level morpheme accurately; During work; Only need the simple smooth at the scene smooth that goes out; And need not high Pingdu place, and make the making of wind electricity blade break away from dependence to high Pingdu place, therefore shorten the making duration, improved make efficiency, reduced cost of manufacture.

Above-mentioned, the present invention adopts the arrangement for adjusting height that is made up of screw, the loading plate that is provided with nut and feet, loading plate is fixedly welded on each following fulcrum place of the basic steelframe of blade male die; Be supported on ground by feet; During application, only need the simple smooth at the scene smooth that goes out, and need not high Pingdu place; Utilize laser leveler indication benchmark; Through the height of each fulcrum of rotary screw adjusting vane formpiston, find the technical scheme of the horizontal morpheme of blade male die then accurately, overcome prior art and had problems and shortcomings long in time limit, that efficient is low, cost is high; The level(l)ing device of a kind of wind-powered blade mold that is provided; Highly regulate through pointwise and to find the integral level morpheme accurately, make the making of wind electricity blade break away from dependence, the purpose that reached the reduction of erection time, raise the efficiency, reduces cost high Pingdu place.
