Abstract
A double-lifting point C-shaped lifting appliance is mainly characterized in that: a lifting lug is formed by cutting a whole plate and is provided with two lifting holes, a lifting lug plate body penetrates through a strip hole on an outer guard board of an upper horizontal beam of a hook body, and the lower end of the lifting lug plate body is fixed on an inner guard board of the upper horizontal beam; the end edge at one side of the lifting lug plate body is connected with a counterweight body; the two sides of each lifting hole of the lifting lug are respectively provided with an annular reinforcing plate; arc-shaped rib plates are arranged on intersection parts of two horizontal beams and vertical beams of the hook body; the end part of a lower horizontal beam of the hook body is provided with an auxiliary counterweight; an inner guard board of the lower horizontal beam of the hook body is provided with an arc-shaped base plate; and outer guard board of the hook body is provided with a traction piece. The double-lifting point C-shaped lifting appliance provided by the utility model can be forced uniformly, and has a good balance performance and high strength, the phenomena of deformation and cracking are avoided, and the performance is more reliable.
Description
Technical field the utility model relates to a kind of lifting device, particularly relates to a kind of suspender that lifts by crane roll bending class steel.
Background technology is in the steel class cargo operation of harbour, and roll bending class steel have occupied certain ratio, along with the change in import and export steel-trading market, and the constantly stable lifting of the large-scale in recent years roll bending market share.The specification of roll bending, model also constantly change simultaneously, and especially deadweight is also increasing, simultaneously owing to the increase of big roll bending working out, and traditional chain bundle pocket handling technology scheme, the requirement that handling efficiency is low, labour intensity can not satisfy production operation greatly.The suspender of China's harbour handling roll bending is single suspension centre C type suspender mostly at present, and this hanger structure is simple, and is easy to operate.But being heat, its interior outer casing surrounds shape (integral body is a sheet material), stress is relatively concentrated at the flex point place, simultaneously in the operation of lifting roll bending, door machine hoisting speed is fast, impact load is bigger, after the long-term operation, C type hook is easy to generate fatigue, following problem often occurs: 1) crackle appears in arc transition position (being the flex point place); 2) stressed more concentrated, suspension centre is yielding.
The summary of the invention the purpose of this utility model is to provide a kind of indeformable, flawless, handling efficiency height, two suspension centre C type suspenders that labour intensity is low.The utility model mainly also is made up of coupler body, hanger and balance weight body.Wherein, coupler body is the side opening box housing that is connected and composed by inside and outside two C type backplates and biside plate cooresponding with it, promptly box beam one end of two levels is connected as a single entity at two ends up and down with a vertical box beam together up and down, the arc gusset is established in the beam and the vertical beam intersection that are preferably in two levels of above-mentioned coupler body, to strengthen the intensity at flex point place, avoid flex point place inner casing cracking.The inner casing of horizontal beam and roll bending endoporus contact portion is provided with the arc backing plate under the above-mentioned coupler body, increasing the contact surface of coupler body and roll bending, in the minimizing lifting operation process to the crimp and the wearing and tearing of roll bending.The horizontal beam end is provided with the front end balance weight body on above-mentioned coupler body, and it is the small box body that is welded by steel plate, according to whole machine balancing needs inside cement or iron block is housed.Hanger is to be formed by a whole plate cutting, is provided with two holes for hoist that can inject snap ring above, and the spacing of this two hole for hoist is decided according to the size of lift heavy.The hanger plate body passes and is fixed on the cylindrical void on the horizontal beam outer casing on the coupler body, and the lower end is fixed on the inner casing of horizontal beam.Preferably the end limit of hanger plate body one side is connected with balance weight body.The both sides that are preferably in each hole for hoist of hanger are equipped with the annular arrangement brace panel, to strengthen hanger intensity, prevent the hanger distortion.Be preferably in that the horizontal beam end is provided with auxiliary counterweight under the coupler body, it can increase counterweight as required.Be provided with traction piece in addition on the outer casing of coupler body, fasten rope in the operation, the loading and unloading personnel proofread and correct the coupler body direction by this drag rope, and it is pierced in the roll bending hole smoothly, lift.
The utility model compared with prior art has following advantage:
1, hanger is two holes for hoist, and each hole for hoist is stressed only to be original half, and therefore stressed more even, balance quality is good.
2, the shape of hanger and fixed position are more reasonable, make suspender intensity height, and performance is more reliable.
3, the hole for hoist both sides are welded with circular brace panel, have increased the resistance to deformation intensity of hanger.
4, coupler body flex point place intensity height has been avoided the phenomenon of distortion, crackle.
5, handling efficiency obviously improves, and the loading and unloading personnel labor intensity reduces, and result of use is good.

Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
In the scheme drawing of two suspension centre C type suspenders illustrated in figures 1 and 2, coupler body 1 is the side opening box housing that is welded by inside and outside two C type backplates 2,3 and biside plate cooresponding with it 4, promptly box beam one end of two levels welds arc gusset 5 with being connected as a single entity at two ends up and down with a vertical box beam in the beam and the vertical beam intersection of two levels of above-mentioned coupler body up and down.The inner casing of horizontal beam and roll bending endoporus contact portion is provided with arc backing plate 6 under the above-mentioned coupler body.The horizontal beam end is provided with front end balance weight body 7 on above-mentioned coupler body.Hanger 8 is to be formed by a whole plate cutting, is provided with two holes for hoist that can inject snap ring above.The hanger plate body passes and is fixed on the cylindrical void on the horizontal beam outer casing on the coupler body, and the lower end is fixed on the inner casing of horizontal beam on the coupler body and the end limit of hanger plate body one side is connected with balance weight body.Be equipped with annular arrangement brace panel 9 in the both sides of each hole for hoist of hanger.The horizontal beam end is provided with auxiliary counterweight 10 under coupler body.On the outer casing of coupler body, be provided with traction suspension member 11 in addition.
