The specific embodiment
Explain further details below in conjunction with the mast-up that is used for handling condenser shell module of accompanying drawing to the utility model.
Shown in Fig. 3-5, being used to of this example mast-up that the condenser shell module is installed comprise the horizontal hanger of girder 31, cross struts 32, oblique strut 33, end face 34, the oblique hanger 35 of end face and bottom surface hanger 36.Each parts of mast-up are welded by shaped steel or steel plate, and version is simple, compact, convenient processing and manufacture, and each member chien shih connects with flange, and it is convenient to install, remove.Said girder is two, is connected with oblique strut through cross struts between two girders, and the main frame that constitutes mast-up jointly carries, and two girders are symmetrically arranged in the both sides of this main frame longitudinal centerline; Said girder end face is welded with horizontal hanger of end face and the oblique hanger of end face, supplies two weight-lifting equipment both sides to lift and separate unit weight-lifting equipment lifting use respectively; Be welded with the bottom surface hanger in the girder bottom surface, through bearing pin to realize being connected of mast-up and condenser shell module.
Girder 31 is main load-carrying members, and its end face is welded with horizontal hanger 34 of end face and the oblique hanger 35 of end face, is used to connect derrick line, and its bottom surface is welded with bottom surface hanger 36, is used to connect the condenser shell module.Totally two of girders 31; (this mast-up longitudinal centerline is the main frame longitudinal centerline to the mast-up longitudinal centerline relatively; The mast-up cross central line is the main frame cross central line) symmetric arrangement; Use several cross struts 32 to be connected therebetween, constitute main frame jointly, as the transition piece of derrick line and condenser shell module with oblique strut 33.Because girder 31 length are bigger, be convenient transportation, every girder 31 can be divided into three sections, and promptly every girder 31 comprises two short beams 41 that are positioned at both sides and is positioned at a middle long beam 42 that short beam 41 uses flange 43 to be connected with long beam 42.
Totally four of the oblique hangers 35 of end face in this example; Every oblique hanger 35 of end face includes a shackle plate; Four oblique hangers 35 of end face are welded on girder 31 inside top surface (promptly near the main frame cross central line); There are two on the every girder 31, are used for 4 liftings of separate unit weight-lifting equipment condenser shell module.Four vertical, horizontal line of centers symmetries of the oblique hanger 35 relative main frames of end face; The shackle plate plane, place and the main frame center-point coplane of every oblique hanger 35 of end face; Thereby guaranteed the shackle plate coplane of the oblique hanger 35 of derrick line and end face; Derrick line can not produce transverse force to shackle plate, has guaranteed the reasonable stress of the oblique hanger 35 of end face.
The position that the horizontal hanger 34 of end face in this example is welded in the girder end face is positioned at the outside of the oblique hanger 35 of end face, and the horizontal hanger of each end face is distributed in the both sides of main frame cross central line.Every horizontal hanger of end face includes a shackle plate, and the horizontal hanger 34 relative main frame longitudinal centerline symmetries of corresponding end face supply two weight-lifting equipments to lift use on two girders 31.The quantity of the horizontal hanger 34 of end face can be confirmed according to the needs that handling is installed.
Like Fig. 6, shown in 7, the bottom surface hanger 36 in this example is welded on bilateral symmetry position, girder 31 bottom surface, can use bearing pin to be connected with the suspension centre of condenser shell module.Two said bottom surface hangers 36 of every said girder 31 bottom surfaces welding, bottom surface hanger 36 is corresponding with the hoisting point position of condenser shell module in the position of weld of girder 31.Said bottom surface hanger 36 is made up of two identical shackle plates 38; Have long shape hole 37 on the shackle plate 38; Can satisfy the horizontal suspension centre spacing of different housings module different requirement; The spacing that two shackle plates are 38 is greater than the thickness of housing module suspension centre plate, thereby can adapt to the difference of the vertical suspension centre spacing of different housings module.
When actual design; After definite girder length and segmentation situation; Can design two bottom surface hangers 36 every girder bottom surface earlier according to said structure according to condenser shell module hoisting point position, then according to the lifting size; At two oblique hangers 35 of end face of every girder end face design; Weld the horizontal hanger 34 of several end faces according to the construction needs at every girder end face again, after bottom surface hanger, the oblique hanger of end face and the horizontal hanger of end face are positioned, oblique strut 33 is installed respectively between oblique hanger of end face and the horizontal hanger of end face is at last fixed with cross struts 32.
Should be noted that at last: above embodiment only in order to the explanation the utility model technical scheme but not to its restriction; Although the utility model has been carried out detailed explanation with reference to the foregoing description; Under the those of ordinary skill in field be to be understood that: still can make amendment or be equal to replacement the specific embodiment of the utility model; And do not break away from any modification of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the middle of the claim scope of the utility model.
