Abstract
The invention relates to a Y-shaped rigid leg for a portal crane. The Y-shaped rigid leg comprises a main support (1), and is characterized in that the main support (1) is arranged in a Y shape; a cross rod (2) is arranged between branches of the Y-shaped main support (1). The upper part of the rigid leg is forked to form two branch box body column structures, so that a designed wind load coefficient is smaller than that of a closed box structure, and a relative support width is also increased, and therefore, the rigidity is improved, the stability is also improved, and the material consumption of the rigid leg is reduced.
Description
Technical field
The present invention relates to a kind of transfer crane, relate in particular to a kind of transfer crane Y type rigid leg.Belong to the elevator machinery technical field.
Background technology
Along with the fast development of logistics, the demand of transfer crane is also day by day increased, these transfer crane steel structures mainly are made of girder, rigid leg, flexible leg at present.
Before the present invention made, the box pillar component was adopted on the top of traditional gate-type crane stiff-leg, and its structure is seen Fig. 1 and Fig. 2.This structure is many with material under the equi-stable condition, and web is thicker, and simultaneously wind force coefficient is larger, thus cause from heavy, to drive time institute's wasted work rate large.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of and economize with material under the equi-stable condition, wind carries also lower transfer crane Y type rigid leg of coefficient.
The object of the present invention is achieved like this: a kind of transfer crane Y type rigid leg, it comprises main pillar, it is characterized in that described main pillar is arranged to the Y type.
Between the branch of described Y type master pillar, be provided with cross bar.
Compared with prior art, the invention has the beneficial effects as follows:
Rigid leg of the present invention top jag is divided into the structures of two casing posts, and to carry coefficient ratio sealing box-structure little for the wind of design like this, and relative support width has also increased, so has increased rigidity, and stability has also improved, and reduced rigid leg use the material amount.

Fig. 2 is the left view of Fig. 1.
Fig. 3 is the Facad structure schematic diagram of transfer crane rigidity leg pillar of the present invention.
Fig. 4 is the left view of Fig. 3.
Wherein:
The specific embodiment
Referring to Fig. 3-Fig. 4, the present invention relates to a kind of transfer crane Y type rigid leg, mainly consisted of by main pillar 1, main pillar 1 is arranged to the Y type, for improving the stability of rigid leg, is provided with cross bar 2 between the branch of Y type master pillar 1.
Claims (2)
1. transfer crane Y type rigid leg, it comprises main pillar (1), it is characterized in that described main pillar (1) is arranged to the Y type.
2. a kind of transfer crane Y type rigid leg according to claim 1 is characterized in that being provided with cross bar (2) between the branch of described Y type master pillar (1).
