Description
Technical field
The present invention relates to hoisting machine tool and the hanging method of a kind of construction method for hanging of large-scale component, particularly large-scale column component.
Background technology
Distribution equipment outside the industrial premises that is comprised of large-sized structural parts or the room in substation project, its member are after the assembling of ground, carry out integral hoisting, in hoisting process, the lifting of column need to be lifted by crane by level, aloft 90-degree rotation, after becoming plumbness, be connected with upright post basic.At present for the lifting of the large-scale column six suspension centre integral lifting that adopt more, only at the column single face, four main suspension centres are set, lifted by crane by main crane, two secondary suspension centres are sling column by secondary crane is auxiliary, after being lifted to certain position, the rope of secondary suspension centre to be removed, column is aloft by manually it being overturn, this just causes: 1 column framework can't be in plumbness fully, is unfavorable for the in place installation of column framework in basic rim of a cup; 2, for steel structure member, the column rod member easily produces distortion; When 3, manually reversing, both time-consuming, dangerous again.If the employing segmental hoisting, speed of application is slow, needs the workmen to carry out construction and installation in the junction of high-altitude member, and security risk is large.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, provide a kind of in hoisting process, but by the hoisting machine tool of the column component of lifting components automatic turning and hanging method.
For achieving the above object, technical scheme of the present invention is: a kind of hoisting machine for upright post member, it is characterized in that being separately installed with fixed pulley at the two ends of lifting cross beam, and two root ropes are walked around respectively fixed pulley, are separately installed with pulley at the two ends of every rope.
The length of above-mentioned lifting cross beam is greater than by the width of hoisting upright column member.
Be fixed with on above-mentioned lifting cross beam for the hoist cable that hangs suspension hook.
A kind of hanging method that utilizes hoisting machine for upright post member hoisting upright column member, it is characterized in that the method is that main suspension hook is connected with hoisting machine for upright post member, be connected with column component with rope with four liftings walking around four pulleys by two fixed pulleys on hoisting machine for upright post member, the assisted suspension cable of auxiliary suspension hook bottom being fixed on column component is connected, in main suspension hook and auxiliary suspension hook lifting process simultaneously, column component automatically by with the level attitude on ground, be turned into the upright position with ground.
above-mentioned four liftings walking around four pulleys are fixed on column component with 8 fag ends of rope, and be distributed in around the center of gravity of column component, every lifting is basic parallel with the axis of column component with the line of the attachment point of 2 fag ends of rope, the face that the line of the attachment point of 4 fag ends of four lifting use rope one ends forms, be positioned at a side of column component center of gravity, and this face is perpendicular to the axis of column component, the face that the line of the attachment point of 4 fag ends of four lifting use rope other ends forms, be positioned at the opposite side of column component center of gravity, and this face is perpendicular to the axis of column component, the face that wherein forms near the line of the attachment point of 4 fag ends of column component bottom and the distance of column component center of gravity are less than near the face of the line formation of the attachment point of 4 fag ends at column component top and the distance of column component center of gravity.
Adopt double-machine lifting crane and the 8 suspension centre lifting methods of main crane, whipline due to the present invention, utilize hoisting machine tool and the lifting rope reasonable installing position, can realize by the hoisting upright column member aloft automatic turning change into position perpendicular to the ground.
the characteristics of hoisting machine tool of the present invention are: utilize lifting cross beam, be arranged on two fixed pulleys at lifting cross beam two ends, walk around respectively two ropes of fixed pulley and be arranged on four formed assembly pulleys of pulley of two rope ends, walk around the end points of four lifting ropes on four pulleys, be fixed on column component, the center of gravity of column component is departed from the fixed position, column component is in the lifting process like this, skew due to center of gravity, column component will automatic rotation, four lifting ropes will move up and down along four pulleys when rotated, thereby realize column component automatic turning in lifting cross beam.
Technical scheme of the present invention is specially adapted to the lifting of large-scale component, has a speed of application fast, the characteristics that security risk is little.
Figure of description
Accompanying drawing 1 be hoisting machine tool of the present invention with by the connection diagram of hoisting upright column member;
Accompanying drawing 2 is the connection diagram when being rotated to the upright position by the hoisting upright column member of the present invention.
The specific embodiment
As shown in Figure 1, be separately installed with 3, two ropes 4 of fixed pulley at the two ends of lifting cross beam 2 and walk around respectively fixed pulley, be separately installed with pulley 5 at the two ends of every rope.In order to guarantee column component 7 in hoisting process, can be turned into smoothly position perpendicular to the ground, the length of lifting cross beam 2 is greater than by the width of hoisting upright column member.
The main suspension hook of main crane 1 is connected with the hoist cable that be used for to hang suspension hook on being fixed on lifting cross beam 2, and the auxiliary lifting rope 8 that is arranged on bottom column component is connected with the suspension hook of whipline.after 4 liftings are walked around respectively 4 pulleys with rope 6, its 8 fag ends are separately fixed on column component 7, and be distributed in around the center of gravity of column component, wherein first lifting is with the attachment point b of 2 fag ends of rope, f is fixed on the top on column component right side, second lifting attachment point a of 2 fag ends of rope, e be fixed on the column component right side below, the 3rd lifting attachment point c of 2 fag ends of rope, g is fixed on the top in column component left side, the 4th lifting attachment point d of 2 fag ends of rope, h be fixed on column component left side below, 4 attachment point e near the column component bottom, f, g, the line of h formed perpendicular to the column component axis the plane and the distance of column component center of gravity less than 4 attachment point a near the column component top, b, c, the line of d is formed perpendicular to the plane of column component axis and the distance of column component center of gravity.
when lifting, main crane and whipline lift by crane simultaneously, after column component breaks away from ground, main crane continues to rise, whipline stops rising or to transferring, keep column component bottom and ground certain distance, the joint face that prevents the bottom is destroyed, at this moment due to the center of gravity of 4 liftings with the misalignment column component of 8 attachment points of rope, namely the center of gravity of column component is with respect to the bottom of the close column component of 8 attachment points, like this in the process of main crane lifting, it is low that the column structure will form the bottom automatically, the upset trend that the top is high, at this moment four pulleys are with the rotation of column component, its upper-lower position is also changing, 4 liftings walking around four pulleys also move up and down along pulley with rope.As shown in Figure 2, when member was turned into position perpendicular to the ground, column built and just is in lifting cross beam 2 and fixed pulley 3 formed " door " shape frame.At this moment, remove the suspension hook of whipline, after making column component bottom slowly fall desired location on the basis, fixing getting final product.
