Description

A kind of reinforced lifting lug of Two bors d's oeuveres lifting heavy component

Technical field

The utility model belongs to construction steel structure mounting technique field more particularly to a kind of Two bors d's oeuveres for lifting heavy component adds Strong type lifting lug.

Background technique

In current steel building development process, the demand of steel construction is increasing, and construction weight is increasingly heavier, It often will appear the lifting of heavy component, in hoisting process, generally can all use lifting lug, the design of lifting lug will be according to the weight of component Amount is arranged, and the component of conventional weight can be met the requirements using general lifting lug, but for the lifting lug of heavy component, be hung Ear is easily torn, and deformation is serious, phenomena such as safety accident easily occur, component is caused to break off relations, influences the lifting of heavy component Safety.

Utility model content

The purpose of this utility model is to overcome the defects of the above-mentioned prior art, and a kind of lifting heavy component proposed The reinforced lifting lug of Two bors d's oeuveres.

To achieve the goals above, the utility model adopts the technical scheme that

A kind of reinforced lifting lug of Two bors d's oeuveres lifting heavy component, including D type shackle plate, stiffener and bolt fastening component； The D type shackle plate front is evenly arranged with bolt hole on the circumference of front, centre is provided with hole for hoist at D-shaped；The D type is hung Otic placode two sides are respectively arranged with the enforced loop plane concentric with hole for hoist；The bolt fastening component is each passed through inside reinforcing ring The bolt hole of plate, D type shackle plate and outside enforced loop plane, is fixed into lifting lug；Two groups of lifting lugs are arranged in parallel, by vertical in two sides It is arranged and the stiffener of D type shackle plate center parallel, the composition reinforced lifting lug of Two bors d's oeuveres；The outer dimension of the enforced loop plane is less than D type shackle plate；The spacing of two groups of lifting lugs is greater than the snap ring width of the suspension hook end on lifting machine.

Further, the stiffener is trapezium structure.

Further, the D type shackle plate and stiffener material are Q345B, and D type lifting lug plate thickness is more than or equal to 25mm, It is fixed with stiffener using full penetration.

Further, the spacing of two groups of lifting lugs is that the snap ring width dimensions of the suspension hook end on lifting machine add 50mm.

The design of the utility model structure is simple, and using effect is good, can hoisting heavy component, pass through setting for trapezoidal stiffener It sets, increases fusion length, increase the contact area of lifting lug and component, while increasing the stress point of component surface, component is lifting It is unlikely to deform in the process, the phenomenon that component surface tears base material because of overstress concentration in hoisting process can be reduced, and hang Ear is that Two bors d's oeuveres type is arranged, it can be achieved that 4 points of liftings, i.e. four wirerope liftings, have the characteristics that safer, stable.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

As shown in Figures 1 to 4, a kind of reinforced lifting lug of Two bors d's oeuveres lifting heavy component, including D type shackle plate 1, stiffener 3 and bolt fastening component 5；1 front of the D type shackle plate is evenly arranged with bolt hole 4, centre setting on the circumference of front at D-shaped There is hole for hoist 6；1 two sides of D type shackle plate are respectively arranged with the enforced loop plane 2 concentric with hole for hoist 6；The bolt fastening Component 5 is each passed through the bolt hole 4 of inside enforced loop plane 2, D type shackle plate 1 and outside enforced loop plane 2, is fixed into lifting lug；Two groups Lifting lug is arranged in parallel, and by being vertically arranged the stiffener 3 with 1 center parallel of D type shackle plate in two sides, constitutes that Two bors d's oeuveres is reinforced to be hung Ear；The outer dimension of the enforced loop plane 2 is less than D type shackle plate 1, can resist the moment bending moment generated in hoisting process；Two groups The spacing of lifting lug is greater than the snap ring width of the suspension hook end on lifting machine, is connected convenient for the snap ring and hole for hoist 6 of suspension hook end It connects, fix.

As a preferred embodiment of the present invention, the stiffener 3 is trapezium structure, the D type shackle plate 1 and stiffener 3 materials are Q345B, and 1 thickness of D type shackle plate is more than or equal to 25mm, are fixed with stiffener 3 using full penetration；Increase weldering Length is stitched, the contact area of lifting lug and component is increased, while increasing the stress point of component surface, component is not easy in hoisting process Deformation can reduce the phenomenon that component surface tears base material because of overstress concentration in hoisting process.

As a preferred embodiment of the present invention, the spacing of two groups of lifting lugs is the snap ring of the suspension hook end on lifting machine Width dimensions add 50mm, and size is more reasonable, do not cause the waste of raw material, save cost.

Specifically used method is as follows: the thickness of D type shackle plate 1, D type shackle plate are calculated according to the weight configuration of heavy component 1 material is Q345B, and bolt hole 4 and hole for hoist 6 are provided on D type shackle plate 1, and processing and fabricating enforced loop plane 2 is reserved and D type The corresponding bolt hole of shackle plate 1 and hole for hoist connect D type shackle plate 1 with stiffener 3 using welding form, and weld seam grade is Then full penetration first-order weld is welded with heavy component to be lifted, bolt fastening component 5 passes through bolt hole 4 and hangs D type Otic placode 1 and enforced loop plane 2 closely connect, and when lifting machine lifts, wirerope is connected by the snap ring and D type shackle plate 1 of suspension hook end It connects.This lifting lug can realize 4 points of liftings, due to devising enforced loop plane 2 and stiffener 3, have preferable work to lifting heavy component With more safe and stable.

The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model Within enclosing.
