Abstract
The utility model discloses a hoisting tool for a large-size ring flange. The technical scheme adopted by the utility model is that the hosting tool for the large-size ring flange comprises a body and is characterized in that the hoisting tool for the large-size ring flange further comprises a clamping part, wherein the clamping part comprises a bent circular arc body; the bent circular arc body and the body are integrally formed; and a through groove is formed in the outer side of the body and the circular arc body. The hoisting tool disclosed by the utility model has the beneficial effects that firstly, the hoisting tool has the advantages of simplicity in processing and low cost and can be used for hoisting the large-size ring flange or other annular parts, and when the hoisting tool is in use, the edge parts of the annular parts are clamped at the clamping part; secondly, the hoisting tool has better generality and can be applied to hoisting of ring flanges with certain sizes; and thirdly, the hoisting tool is high in safety and favorable in firmness, and potential safety hazards in the use process of a hoisting strap are avoided and the hoisting cost is reduced.
Description
Technical field
The utility model relates to the work piece hoisting technical field, especially relates to a kind of large-sized flange dish lifting special tool.
Background technology
In recent years, China's wind-powered electricity generation industry development has a gratifying situation, and has grasped megawatt-level wind unit manufacturing technology basically, has begun to take shape the industrial chain of producing major parts such as blade, gear case, electrical generator and pylon part.The wind power tower flange is one of crucial component part in the wind power technology equipment, and wind power tower accounts for 15% in complete machine cost proportion, so in enormous quantities, production tower flanges cheaply is significant for the whole competitiveness that improves wind power equipment.The diameter of this kind tower flanges does not wait from about 1.5-6m; Thickness is about 300mm; Prior art adopts hanging belt in lifting; But because the edge of flange is sharper keen, the metal piece with sharpened edge is very easy to isolate hanging belt, and using in process of production has the hanging belt of cut to have potential danger.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming that exists in the prior art; Long, safe large-sized flange lifting device of a kind of easy to use, life-span is provided; This kind lifting device can substitute hanging belt fully, but the repeated multiple times use has reduced use cost.The technical scheme that adopts is: a kind of large-sized flange dish lifting device; Comprise body, it is characterized in that: said large-sized flange dish lifting device also comprises holding part, and said holding part comprises crooked circular arc body; Said circular arc body and body are made into integration, and there is through slot in the said body and the circular arc body outside.
The technical scheme of the utility model also has: said holding part also comprises the brace panel that is welded on said circular arc body both sides.
The technical scheme of the utility model also has: said body and circular arc body are processed by channel-section steel or I-beam section.
The beneficial effect of the utility model is: 1) this instrument has simple, the with low cost advantage of processing; During use, the edge of waiting to lift workpiece is placed the inboard of circular arc body, by means of the effect of holding part; Hold edge of work and accomplish the operation that lifts; Not only can be used in the lifting of flange, also can be used in the lifting of other annular type parts, need only during use annular type part edge parts are installed in retaining part.
2) this instrument has good versatility, and same instrument can be to being applied in the flange lifting in the certain size scope.
3) this instrument is safe, and fastness is good, the potential safety hazard of having avoided hanging belt in use to exist, better protect the integraty of edge of work, and reduced hoisting cost.
Description of drawings
Accompanying drawing 1 is the utility model structural representation, and wherein 1 is body, the 2nd, and circular arc body, the 3rd, through slot, the 4th, brace panel.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described.This large-sized flange dish lifting device comprises body 1 and holding part, and holding part comprises circular arc body 2 and the brace panel 4 that is welded on circular arc body 2 both sides, in the body 1 and circular arc body 2 outsides through slot 3 is arranged.For easy to process, this large-sized flange dish lifting device body 1 can be made into integration by channel-section steel or I-beam section with circular arc body 2.
During use, holding part is cooperated with flange or circular piece edge to be lifted, will lift chain then and pass through slot, will lift chain and hang over last the getting final product of driving a vehicle.
Certainly; Above-mentioned explanation is not the restriction to the utility model; The utility model also be not limited only to above-mentioned for example, variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also belong to the protection domain of the utility model.
