Abstract
The utility model relates to a kind of transfer crane del cross section truss girder, it is characterized in that it comprises main chord (1), side subchrod (2), lower main chord (3), track (4), upper horizontal chord member (5) and upper inclined chord (6) composition, described upper main chord (1), upper horizontal chord member (5) and upper inclined chord (6) form horizontal truss structure, described upper main chord (1), side subchrod (2) and lower main chord (3) form inclined-plane truss structure, and described track (4) is arranged at the bottom of lower main chord (3).The utility model transfer crane del cross section truss girder is truss structure, and it is little that wind carries coefficient ratio box-structure, and therefore stability significantly improves.Under same cross section property condition, truss structure sectional area is less, which in turn reduces and uses material amount, can greatly reduce complete machine weight, also reduce power during driving.
Description
Technical field
The utility model relates to a kind of transfer crane, particularly relates to a kind of transfer crane del cross section truss girder.Belong to the technical field of 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 are formed primarily of girder, rigid leg, flexible leg.
Before the utility model makes, the girder of traditional transfer crane is become the housing of box section by Plate Welding, and lower housing portion inserts the I-beam section (its structure is shown in accompanying drawing 1-Fig. 2) that welding one runs for electric block.This structure is many with material under equi-stable condition, and simultaneously because housing is closed structure, cause internal weld seams difficult treatment, welding quality cannot ensure.And wind force coefficient is comparatively large when outdoor application, so cause from heavy, drive time institute's wasted work rate large, cost is also higher.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and carry the lower transfer crane truss-like girder of coefficient with material province, welding production convenience, wind under equi-stable condition.
The purpose of this utility model is achieved in that a kind of transfer crane del cross section truss girder, it comprises main chord, side subchrod, lower main chord, track, upper horizontal chord member and upper inclined chord composition, described upper main chord, upper horizontal chord member and upper inclined chord form horizontal truss structure, described upper main chord, side subchrod and lower main chord form inclined-plane truss structure, described side subchrod and upper main chord and lower main chord form triangular structure, and described track is arranged at the bottom of lower main chord.
Compared with prior art, the beneficial effects of the utility model are:
The utility model transfer crane del cross section truss girder structure, it is little that wind carries coefficient ratio box-structure, and therefore stability improves.Owing to being truss structure, less at same cross section property condition pipe type structural section area, which in turn reduces and use material amount, can greatly reduce complete machine weight, also reduce power during driving.
