Description
Technical field
The present invention relates to heavy machine and set up the frame method for turning for preparing work, installing area, particularly a kind of method of heavy frame side direction upset.
Background technology
At present; For frame weight in the heavy frame more than 1000 tons; Domestic main employing hydraulic pressure lift is passed to cooperate with hydraulic pressure and is installed, and the method needs to make, install higher lifting and is used for arranging hydraulic lifting apparatus with steel structure frame, therefore needs higher factory building to arrange.For the ordinary plant structure, use this installation method need remove the part mill construction, and need to use large-scale crane to cooperate the installation lifting to use framed structure; Receive the weight limits of frame own in addition; Need to adopt severe duty hydraulic pressure lift and hydraulic pressure slide device, therefore, frame upset infusion of financial resources is big; Operating efficiency is low, has a strong impact on construction speed.
Summary of the invention
The present invention be directed to the loaded down with trivial details and defective of the medium and heavy frame switching process of prior art, the method that provides a kind of simple in structure, easy to operate heavy frame side direction to overturn.
Realize that the technical scheme that above-mentioned purpose adopts is: a kind of method of heavy frame side direction upset, this method mainly are applicable to the side direction upset after large-scale frame assembling is accomplished, and it carries out according to following steps:
A, set up support post in foundation ditch inside; With the frame of assembled, under the cooperation of auxiliary member and upset mold, turn on the support post;
B, in the frame both sides of foundation ditch mouth turnover bracket is installed, affixed rotation is supported on the turnover bracket; In the inner inner support of installing of frame, the main rotating beam in the inner support supports with rotation and is connected through main rotating shaft; Main rotating shaft and frame center of gravity are eccentric to be provided with;
C, choose suspension centre at the frame afterbody, this suspension centre is connected with overhead traveling crane through steel rope;
D, withdraw from support post, frame integral body is contained on the turnover bracket by the main rotating shaft frame; Because axle center and the frame centre-of gravity shift of main rotating shaft are overturn at frame self gravitation effect lower bearing bracket, during upset,, and cooperate and move with the suspension centre of overhead traveling crane lift carriage afterbody, frame is rotated the day after tomorrow car of putting in place and is stopped lifting and mobile;
After e, frame upset finished, elder generation is mounting seat and cushion blocking in the bottom, and uses the jack base for supporting; Around frame, supporting apparatus is installed again, is withdrawn from turnover bracket, under jack cooperated, it is inner that frame is implemented at foundation ditch fully, removes supporting apparatus.
The eccentric distance of the axle center of main rotating shaft and frame center of gravity is 50-100mm.
Definite method of eccentric distance: calculating its controlled turning effort power according to the tonnage of on-the-spot overhead traveling crane, according to the weight of frame self, is foundation with turning effort power, calculates need the squint distance in main rotating shaft axle center of frame center of gravity.
Compare with traditional method for turning, this method for turning disclosed by the invention can be realized the installation of heavy frame in the ordinary plant under the situation of not removing mill construction, and operation height reduces, and has reduced the risk of difficulty of construction and aloft work simultaneously; Do not need to promote and the hydraulic pressure slide device, only need to use the factory building overhead traveling crane can realize the frame upset, practice thrift construction cost by large-scale crane, heavy hydraulic; Improve operating efficiency, the reduction of erection time, controllability is strong; Improve the safety and the reliability of camp site, be applicable to the upset of various heavy frames.

Among the figure: frame 1, inner support 2, main rotating shaft 3, rotation supports 4, suspension centre 5, turnover bracket, 6, support post 7, foundation ditch 8, main rotating beam 9, base 10, cushion blocking 11, jack 12, supporting apparatus 13.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
The disclosed this frame method for turning of the present invention is applicable to various heavy frames, and present embodiment is an example with oval-shaped drop press frame, and its method for turning carries out according to following steps.
A, set up support post 7 in foundation ditch 1 inside, the frame 1 of assembled is turn on the support post 7 under the cooperation of auxiliary member and upset mold, auxiliary member is generally instruments such as backing plate and jack, and overturn mold and backing plate are traditional arcuate structure.Frame 1 side stands on the support post 7, position shown in accompanying drawing 1.
B, at the near coal-mine place of foundation ditch 1, the both sides of frame install turnover bracket 6, affixed rotation supports 4 on the turnover bracket 6, during practical operation; The pre-buried fixedly backing plate in the foundation ditch both sides; Be used to weld fixedly turnover bracket, prevent in the frame switching process centre-of gravity shift to take place, cause the turnover bracket displacement.In the inner inner support 2 of installing of frame 1, the main rotating beam 9 in the inner support 2 and rotation are supported 4 and are connected through main rotating shaft 3, between main rotating beam and the main rotating shaft, be respectively the pivotally attached type of attachment between main rotating shaft and the rotation support.The axle center of main rotating shaft is set the center of gravity off-centre of main rotating shaft 3 and frame 1 and the eccentric distance of frame center of gravity is 50-100mm.
C, choose suspension centre 5 at frame 1 afterbody, this suspension centre 5 is connected with overhead traveling crane through steel rope.
D, withdraw from support post 7, frame 1 integral body is contained on the turnover bracket 6 by 3 of main rotating shafts.Because the axle center of main rotating shaft 3 and the centre-of gravity shift of frame 1; Overturn at frame self gravitation effect lower bearing bracket, during upset, with the suspension centre 5 of overhead traveling crane lift carriage afterbody; And cooperate mobile; Put in place day after tomorrow car of frame 1 rotation stops to promote and moving, and can realize 90 ° of upsets of frame, shown in accompanying drawing 2-3.General reverses direction and suspension centre direction are same direction, and promoting suspension centre with overhead traveling crane is in switching process, to give and hoisting force that makes progress of the heavier end of frame, and the assurance frame is steadily carried out in switching process.
E, see accompanying drawing 3-4, after frame 1 upset finishes, mounting seat 10 and cushion blocking 11 in the bottom earlier, and with jack 12 base for supporting 10; Supporting apparatus 13 is installed around frame 1 again; Withdraw from turnover bracket 6, under the cooperation of jack 12, generally use four 1000 tons jack base for supporting; Cooperate cushion blocking 11 simultaneously; Till complete compacting, frame 1 is implemented in foundation ditch 8 inside fully, remove supporting apparatus 13.The frame inner support is withdrawn from the site clearing then, accomplishes upset work.
Definite method of the eccentric distance of main rotating shaft and frame center of gravity: the tonnage according to on-the-spot overhead traveling crane calculates its controlled turning effort power; Weight according to frame self; With turning effort power is foundation, calculates need the squint distance in main rotating shaft axle center of frame center of gravity.
The present invention also is applicable to the upset engineering of the heavy frame of other structures, mainly is that the cooperation through devices such as on-the-spot overhead traveling crane and turnover brackets replaces equipment such as existing large-scale crane, heavy hydraulic lifting and hydraulic pressure slide device.In addition, in switching process, only need to make the steel structure turnover bracket that surpasses frame installation body height and get final product.
