Abstract
The utility model discloses a platform support member for a bridge crane. A cross section (1) of the platform support member for the bridge crane perpendicular to the thickness direction is composed of a left part and a right part. The left part is a rectangle part (2), and the right part is a trapezoid part (3). The right side of the rectangle part (2) and the lower bottom side of the trapezoid part (3) are the same. A welding arrangement part (4) is arranged at the lower left corner of the rectangle part (2). The platform support member for the bridge crane is low in weight.
Description
Technical field:
The utility model relates to a kind of hoisting crane load-carrying element of walking on stage, and specifically is the crane in bridge type load-carrying element of walking on stage.
Background technology:
Hoisting crane belongs to a kind of of elevator machinery, and metal construction is the skeleton of hoisting crane, and for crane in bridge type, the load-carrying element of walking on stage is very important, its performance to crane in bridge type whether safely and effectively operation play key role very.The crane in bridge type of the prior art load-carrying element of walking on stage all adopts angle steel; Angle steel is commonly called as angle bar, is the rectangular steel of the orthogonal one-tenth dihedral in both sides; When it is widely used in crane in bridge type when walking on stage supporting construction, the weight of whole crane span structure increase greatly and cost higher.
The utility model content:
The technical matters that the utility model will solve is, the less and lower-cost crane in bridge type of a kind of weight load-carrying element of walking on stage is provided.
For solving the problems of the technologies described above; The utility model adopts a kind of like this crane in bridge type load-carrying element of walking on stage: the walk on stage cross section perpendicular to thickness direction of load-carrying element of said crane in bridge type is made up of left and right sides two parts; Left part is a rectangular portion; Right part is trapezoidal portion, and the right edge of said rectangular portion and trapezoidal 's bottom is that the lower left corner of said rectangular portion has weld seam arrangement portion with on one side.
Said weld seam arrangement portion is set to chamfering.
Said chamfering is 10*45 °.
After adopting above structure; The utility model compared with prior art has the following advantages: the walk on stage cross section perpendicular to thickness direction of load-carrying element of said crane in bridge type is made up of left and right sides two parts, and left part is a rectangular portion; Right part is trapezoidal portion; The right edge of said rectangular portion and trapezoidal 's bottom is that said left and right sides two parts are same plane with on one side, scientific structure and with the orthogonal angle steel that becomes dihedral in both sides than having reduced weight greatly; The lower left corner of said rectangular portion has weld seam arrangement portion, can be effective during installation and the complete coating structural weld seam of walking on stage.
As preferably, said weld seam arrangement portion is set to chamfering, processes simple to operation.
As preferably, said chamfering is 10*45 °, has more reasonably reserved the space of weld seam.
Description of drawings:
Fig. 1 is the walk on stage installation site scheme drawing of load-carrying element of the utility model crane in bridge type
Fig. 2 is the walk on stage structural representation of load-carrying element of the utility model crane in bridge type.
As shown in the figure: 1, perpendicular to the cross section of thickness direction, 2, rectangular portion, 3, trapezoidal portion, 4, weld seam arrangement portion.
The specific embodiment:
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
As illustrated in fig. 1 and 2; The utility model crane in bridge type load-carrying element of walking on stage is made up of left and right sides two parts perpendicular to the cross section 1 of thickness direction; Left part is a rectangular portion 2; Right part is trapezoidal 3, and the right edge of said rectangular portion 2 and trapezoidal 's 3 bottom is that the lower left corner of said rectangular portion 2 has weld seam arrangement portion 4 with on one side.
The utility model crane in bridge type load-carrying element of walking on stage is made up of left and right sides two parts perpendicular to the cross section 1 of thickness direction; Left part is a rectangular portion 2, and right part is trapezoidal 3, and the right edge of said rectangular portion 2 and trapezoidal 's 3 bottom is with on one side; Said left and right sides two parts can be regarded as and fuse; Processed by same material, also be appreciated that to both integrally weldedly, welding rod can adopt with both identical materials also can adopt performance better material than both.This crane in bridge type load-carrying element of walking on stage is of a size of 6*300*700, and * is a multiplication sign, δ=6.
The lower left corner of said rectangular portion 2 has weld seam arrangement portion 4, specifically multiple setting can be arranged, in the present embodiment; Said weld seam arrangement portion 4 is set to chamfering, specifically is of a size of 10*45 °, certainly; Also can be set to other, such as half round cut, square notch etc.
This crane in bridge type load-carrying element of walking on stage adopts the mode of welding when mounted, and welding rod adopts E4303.
Below only just the preferred plan of the utility model embodiment is described, can not be interpreted as it is restriction claim.The utility model not only is confined to above embodiment, and its concrete structure allows multiple variation, as long as the variation in these claims is all within the protection domain of the utility model.
