Abstract
The utility model relates to a truss type flexible leg of a portal crane. The truss type flexible leg of the portal crane comprises a pair of main supports (1) and a lower transverse beam (3) and is characterized in that the pair of main supports (1) have tubular truss structures; the lower transverse beam (3) is arranged at the bottom of the pair of main supports (1); and a plurality of secondary pipes (2) are arranged between the pair of main supports (1). The flexible leg has a tubular truss structure and the wind load coefficient is less than that of a box-shaped structure, so the stability is improved. According to the tubular structure, the sectional area of the tubular structure is smaller than that under the same section characteristic condition, so that the using amount of materials is reduced, the weight of the whole machine is greatly reduced and the power during driving is reduced.
Description
Technical field
The utility model relates to a kind of transfer crane, relates in particular to a kind of transfer crane truss-like flexible leg.The technical field that belongs to elevator machinery.
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 up of girder, rigidity leg, flexible leg.
Before the utility model was made, the flexible leg of traditional transfer crane was formed (its structure is seen accompanying drawing 1) by the two box pillar components and the bottom on top by the cross sill of box section.This structure is many with material under equal stability condition, and wind force coefficient is bigger simultaneously, so cause from heavy, to drive time institute's wasted work rate big.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of and under equal stability condition, economizes with material, and wind carries the also lower transfer crane truss-like flexible leg of coefficient.
The purpose of the utility model is achieved in that a kind of transfer crane truss-like flexible leg; It comprises a pair of main pillar and cross sill; Said a pair of main pillar is arranged to the tubular type truss structure; Said cross sill is arranged at the bottom of a pair of main pillar, between said a pair of main pillar, also is provided with a plurality of looped pipelines.
Compared with prior art, the beneficial effect of the utility model is:
The utility model flexible leg is the tubular type truss structure, and it is little that wind carries the coefficient ratio box-structure, so stability has improved.Owing to be tubular structure, less at same cross section property condition pipe type structural section area, this so reduced the material amount of using, can reduce complete machine weight greatly, also reduced the power when driving.

The specific embodiment
Referring to Fig. 3-Fig. 4; The utility model relates to a kind of transfer crane truss-like flexible leg; Mainly be made up of with cross sill 3 a pair of main pillar 1, said a pair of main pillar 1 is arranged to the tubular type truss structure, and said cross sill 3 is arranged at the bottom of a pair of main pillar 1; Between said a pair of main pillar 1, also be provided with a plurality of looped pipelines 2, in order to increase the intensity of flexible leg.
Claims (1)
