Abstract
A welded type crane hanger beam relates to a beam structure used in a hydropower station bridge station. The beam of the prior art is a forged piece; the blank thereof is a rectangle solid part, not only has complex manufacturing procedure, but also has larger amount of machining workload and high manufacturing cost. The beam of the invention comprises a box type balance beam, two box type carrier bars and two minor axes; both sides of the box type balance beam are respectively welded with the box type carrier bar; two minor axes are welded inside the two box type carrier bars along a center line; the box type balance beam and the box type carrier bars are welded together by an upper cover plate and a lower cover plate. The box type balance beam is internally welded with a ventral shield and a partition board. The welded type crane hanger beam has the advantages of reasonable structure, simple manufacture technique, few processing working hours, low manufacturing cost, etc.
Description
Technical field
The present invention relates to the power station and use crane in bridge type, particularly bridge machine in power station is with the beam structure of suspender.
Background technology
Like Fig. 1,2,3, shown in 4, the power station crane in bridge type because the rotor deadweight is bigger, needs two crane in bridge type to hang up a big equalizing bar 1 simultaneously and unites lifting when the lifting generator amature.Crossbeam 2 is installed in the middle part of big equalizing bar 1, and the middle part section of crossbeam 2 is square, and there is the macropore 2-1 that suspension ring 3 are installed at the center, and the both sides of crossbeam 2 have minor axis 2-2 to be bearing on the side plate 4 of big equalizing bar 1, are provided with thrust baring 5 between crossbeam 2 and the suspension ring 3.Like this, during crane in bridge type lifting generator amature, rotor can rotate under equalizing bar and swing, and is convenient to fitting operation.
The crossbeam 2 of prior art is a forging, promptly adopts the method for forging to make.Because forging blank is the rectangular solid part, add general plucking base on floor type boring machine earlier in man-hour, boring, bore hole then, reface minor axis.Complex procedures not only, and because blank dimension is excessive and do not have the middle part macropore, so the work capacity of machine maple processing is very big, manufacturing cost is higher.
Summary of the invention
The object of the invention is exactly in order to overcome the shortcoming of prior art, a kind of welded type crane hanger beam to be provided, and it has rational in infrastructure, and manufacturing process is simple, and machining period is few, advantages such as low cost of manufacture.
The present invention realizes its purpose through following technical scheme:
A kind of welded type crane hanger beam; It is characterized in that: described crossbeam is made up of box-shaped equalizing bar, box-shaped carrier bar and minor axis; Both sides at the box-shaped equalizing bar are welded the box-shaped carrier bar respectively; Two minor axises are welded in two box-shaped carrier bars along line of centers respectively, and box-shaped equalizing bar and box-shaped carrier bar be with upper cover plate, lower cover weld together, and on upper cover plate, lower cover, process the macropore that is used to carry suspension ring.
Be welded with web in described box-shaped equalizing bar and the box-shaped carrier bar.
Also be welded with dividing plate in the described box-shaped carrier bar.
The present invention compared with prior art owing to after crossbeam adopts welded structure, not only reduced the weight of crossbeam, and the macropore in the equalizing bar only processes on upper and lower cover plate and gets final product, and reduced machining period widely, reduced the manufacturing cost of crossbeam.Because crossbeam is welded into box type construction with quality steel plate, and in box girder, be welded with web, dividing plate, and carry out defect detecting test by the quality loop butt welded seam of member, guaranteed the intensity and the stability requirement of box girder, guaranteed the safe in utilization of crossbeam.Owing to be provided with thrust baring above the crossbeam, the moment of flexure that lift heavy produces is born by box girder, and the minor axis on both sides is bearing on the web of big equalizing bar, hang thing with assurance and can in equalizing bar, rotate and swing, thus reasonable in design of the present invention, convenient installation and operation.
Description of drawings
Fig. 1 is the front view of power station crane in bridge type lifting rotor with suspender (big equalizing bar);
Fig. 2 is the A-A cross sectional drawing of Fig. 1;
Fig. 3 is the existing front view that forges crossbeam;
Fig. 4 is the existing birds-eye view that forges crossbeam;
Fig. 5 is a kind of front view of welded type crane hanger beam;
Fig. 6 is the birds-eye view of Fig. 5.
The present invention is further described through preferred embodiment below in conjunction with accompanying drawing.
The practical implementation method
Like Fig. 5, shown in 6; A kind of welded type crane hanger beam; Form by box-shaped equalizing bar 6, box-shaped carrier bar 7 and minor axis 8, weld 7, two minor axises 8 of box-shaped carrier bar in the both sides of box-shaped equalizing bar 6 respectively and be welded in two box-shaped carrier bars 7 respectively along line of centers; Box-shaped equalizing bar 6 and box-shaped carrier bar 7 usefulness upper cover plates 9, lower cover 10 weld togethers, and on upper cover plate 9, lower cover 10, process the macropore that is used to carry suspension ring.
Described box-shaped equalizing bar 6 adopts the manufacturing of high-quality plate iron with box-shaped carrier bar 7, and in box girder, is welded with web 11, with the intensity and the rigidity of guard box ellbeam.
Also be welded with dividing plate 12 in the described box-shaped carrier bar 7, to guarantee the stability of box girder.
All weld seams of the present invention all carry out magnetic particle testing, must reach the quality loop of framing member, thereby guarantee the safe in utilization of crossbeam.
