Abstract
The invention relates to a special lifting frame, which comprises a set of fixing frame composed of two bottom beams; the two bottom beams of the fixing frame are connected and fixed through a stud; the length directions of the bottom beams are same to the axial direction of a columnar workpiece; two lifting lugs connected with a steel wire rope through shackles are at least arranged on the bottom beams of the fixing frame; two cushion blocks contacted with the workpiece are at least arranged on the bottom beams; because the length directions of the bottom beams forming the fixing frame are same to the axial direction of the columnar work-piece, the fixing frame is installed at the bottom of the workpiece in advance; the two bottom beams are fixed through the stud; tensile force of the two bottom beams is born; because the lifting lugs are arranged on the bottom beams, the fixing frame can be lifted through the lifting lugs; the large columnar workpiece on the fixing frame is lifted together; and thus, the position of the work-piece is changed.
Description
Technical field
The present invention relates to field of machining, be specifically related to a kind of processing special hoisting bar of large-scale Cylindrical workpiece.
Background technology
Workpiece forging blank out after, need to carry out machine up to it.In the process of whole machine up, need to process each face of workpiece, often need the position converting workpiece, just can complete the processing of all.Particularly when workpiece heavier-weight, the hoisting weight of the ringbolt that can be above standard, is difficult to direct lifting.Moreover for light base workpiece, do not allow to hole on workpiece, even if welding hanger also has strict requirement.For large-scale cylindrical workpiece, its profile is smooth arc, must solve and be lifted by crane by workpiece, realize the problem of evolution.
Summary of the invention
The object of the present invention is to provide a kind of special hoisting bar, the cylindrical workpiece larger for weight carries out lifting operation.
For achieving the above object, technical scheme of the present invention is: a kind of special hoisting bar, comprise the one group of fixed mount be made up of two bottom girders, fixed by Stud connection between two bottom girders of fixed mount, the length direction of described bottom girder is identical with the axis of cylindrical workpiece, the bottom girder of described fixed mount is at least provided with two hangers be connected by buckle with steel rope, described bottom girder is at least provided with two pieces with the cushion block of absorption surface.
When adopting technique scheme, the one group of fixed mount be made up of two bottom girders, the length direction of bottom girder is identical with the axis of cylindrical workpiece.Like this, in advance fixed mount is arranged on the bottom of workpiece, by stud, two bottom girders is fixed, and bear the pulling force of two bottom girders.Owing to being provided with hanger on bottom girder, like this, can fixed mount be lifted by crane by hanger, lift by crane together with the large-sized column shaped workpiece that fixed mount is placed, complete the evolution to workpiece.
Further, described hanger is symmetricly set on the bottom girder of fixed mount.
Further, described hanger is disposed on the bottom girder of fixed mount.
Further, described bottom girder is provided with the curved portions with absorption surface.The area of contact that curved portions can increase bottom girder and workpiece is set, makes workpiece meeting in lifting process more stable.
Further, the diameter of described stud is 80mm.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of a kind of special hoisting bar embodiment of the present invention.
Detailed description of the invention
As shown in Figure 1, special hoisting bar of the present invention, includes one group of fixed mount, and fixed mount is the stressed member of lifting workpiece.Fixed mount is made up of two identical bottom girders 1.Bottom girder 1 has one section of cambered surface, this cambered surface is mated with the cambered surface of the columniform workpiece treating lifting, and the cambered surface on bottom girder is no more than 1/4th of the cambered surface of workpiece.On bottom girder, broad ways has through hole, can insert stud 2 in through hole, and stud 2 at least needs to select diameter to be 80mm's.And after installing stud 2, two bottom girders 1 are fixed as a whole fixed mount, and when lifting workpiece, stud 2 directly contacts with between workpiece, such stud 2 directly would not bear the pressure of workpiece, but is subject to the pulling force of bottom girder 1, can avoid bending distortion.Above bottom girder 1, be welded with hanger 3, hanger 3 is connected with steel rope by shackle.Steel rope according to workpiece weight and national standard, directly can be selected.When carrying out lifting, the total weight of workpiece and suspension bracket is more than 200T.Therefore, according to GB8918-2006, select circle stock steel cable 6 × 37, Nominal Tensile is 170kg/, and sectional area is the steel rope of 70mm.The stressing conditions of thru-bolt is more responsible, and when lifting by crane for workpiece, all weight is born by least two thru-bolts, now reaches maxim by lateral load force.
During use, first two bottom girders 1 are placed in the both sides of workpiece along the axis of workpiece, then put on stud 2, and use nut locking.Afterwards steel rope is fixed on hanger 3 by shackle.Check errorless after lift by crane in advance, sling height, greatly about 300mm, after lifting, reexamines jam nut and stud 2, it is locked further.Lift by crane further again, and transhipment and upset workpiece, make it reach the requirement of processing.This suspension bracket is exclusively used in large-tonnage cylindrical work and moves in the lifting can not carried out under punching and welding operation and upset, can simple and practical ground technical solution problem.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for a person skilled in the art, under the prerequisite not departing from structure of the present invention, can also make some distortion and improvement, and such as, hanger can be arranged at interval.These also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
