Abstract

The utility model discloses a simple and portable girder lifting device for wind turbine blades. The simple and portable girder lifting device comprises a cross beam, a left clamp, a right clamp, a lifting lug and plug pins, wherein the lifting lug is formed in the middle of the cross beam, and the left clamp and the right clamp are movably and adjustably connected at two sides of the cross beam in a penetrating mode; the two ends of the cross beam are connected with the plug pins for preventing the left clamp and the right clamp from sliding off the cross beam in an inserting mode; the left clamp and the right clamp are composed of an outer clamp plate, an inner clamp plate, a sleeve pipe and a bolt, and the outer clamp plate and the an inner clamp plate are connected onto the cross beam in the penetrating mode; the sleeve pipe and the bolt are fixedly arranged on the inner clamp plate, and the bolt penetrates through the outer clamp plate and is screwed by a nut; and the inner clamp plate and the outer clamp plate are fixed together. During use, the girder lifting device is hoisted by a travelling crane to be inserted into an assembled beam box from the upper part of the beam box, the inner clamp plate and the outer clamp plate of the left clamp and the right clamp are respectively positioned at the inner side and the outer side of a front beam and a rear beam, then the front beam and the rear beam (web) are clamped by the inner clamp plate and the outer clamp plate, two frock clamps are installed in place, and finally the girder lifting device can carry out the lifting operation. The girder lifting device has the characteristics of simpleness, portability, simpleness in operation and high using and working efficiency.

Description

A kind of wind power generation blade crossbeam lifting appliance of simple light

Technical field:

The utility model belongs to field of machine tool equipment, refers in particular to a kind of wind power generation blade crossbeam lifting appliance of simple light.

Background technology:

In the middle of the production of wind electricity blade; Crossbeam (web) is to bond on the housing with adhesive after the moulding, because the bonding of crossbeam need be accomplished with lifting device is auxiliary in the big bonding process of the weight of crossbeam, complicated tool operation is complicated; It is long to expend man-hour, and efficient is low.Therefore design simple light, lifting device simple to operate just seems necessary.

Summary of the invention:

The purpose of the utility model is in order to overcome the shortcoming of above-mentioned prior art, and a kind of simple light, wind power generation blade crossbeam lifting appliance simple to operate are provided.

For realizing above-mentioned purpose; The technical scheme that the utility model provides is: a kind of wind power generation blade crossbeam lifting appliance of simple light; Include crossbeam, left anchor clamps, right anchor clamps, hanger and latch; Hanger is formed in crossbeam middle part, and the movable adjustable ground cross-under of left anchor clamps and right anchor clamps is in the both sides of crossbeam, is plugged with at the two ends of crossbeam to prevent the slip away latch of crossbeam of left anchor clamps and right anchor clamps.

A left side anchor clamps and right anchor clamps are made up of external splint, inner splint, sleeve pipe and bolt, external splint and inner splint cross-under on crossbeam, sleeve pipe and being bolted on the inner splint, bolt passes external splint and screws with nut, inner splint and external splint are fixed together.

After adopting technique scheme; During use; This crossbeam lifting appliance of slinging with driving a vehicle inserts from the beam box top that assembles; And the inside and outside clamping plate that make left and right sides anchor clamps lay respectively at the inside and outside both sides of front and rear beam, use the tight front and rear beam of curb pins plate holder (web) then, and two frock clamps are in place and can carry out lifting operation.This crossbeam lifting appliance has simple light, characteristics simple to operate, as to use high efficiency.

Description of drawings:

Fig. 1 is the sectional structure chart of the utility model lifting appliance;

Fig. 2 is the left TV structure figure of the utility model lifting appliance;

Fig. 3 is the sectional structure chart of the utility model lifting appliance left and right sides anchor clamps;

Fig. 4 is the left TV structure figure of the utility model lifting appliance left and right sides anchor clamps.

The specific embodiment:

Combine accompanying drawing to set forth the utility model in detail at present:

Like Fig. 1～shown in Figure 4; This simple light blade of wind-driven generator crossbeam lifting appliance is made up of crossbeam (3), left anchor clamps (1), right anchor clamps (2), hanger (4), latch (10); Left and right sides anchor clamps (1,2) are through on the crossbeam (3) through the rectangular through-hole of being opened on the clamping plate, and crossbeam (3) two ends are provided with latch (10) and prevent that anchor clamps from skidding off.Left and right anchor clamps (1,2) are to be combined by inner splint (6), external splint (5), bolt (8) and sleeve pipe (7), and external splint (5) is a slab construction, and inner splint (6) is made according to the crossbeam cross sectional shape.

A whole set of crossbeam lifting appliance is divided into blade root end and blade tip end two cover stone tongs; In use, two stone tongs are sling, inserted from the beam box top that assembles with driving; The inside and outside clamping plate (5,6) of left and right sides anchor clamps (1,2) place the inside and outside both sides of front and rear beam (web) respectively; Bolt (8) on the inner splint (6) is passed the circular port on the external splint (5), and the nut (9) of on bolt (8), screwing on clamps front and rear beam (web) with inside and outside clamping plate (5,6), can lift operation.

The above only is the preferred embodiment of the utility model, is not the utility model is done any pro forma restriction.Any those of ordinary skill in the art; Do not breaking away under the utility model technical scheme scope situation; All the method for above-mentioned announcement capable of using and technology contents are made many possible changes and modification to the utility model technical scheme, or are revised as the equivalent embodiment of equivalent variations.So every content that does not break away from the utility model technical scheme, the equivalence of doing according to shape, structure and the principle of the utility model changes, and all should be covered by in the protection domain of the utility model.
