Abstract

The invention relates to a main beam for a portal crane. The main beam comprises a box beam and is characterized in that the cross section of the box beam is square, H-shaped steel is arranged on the left side and the right side of the box beam and connected with the upper side face and the lower side face of the box beam, the middle portion of the H-shaped steel is provided with a rectangular through hole, the upper side faces of the H-shaped steel are connected with a top plate, and the lower side faces of the H-shaped steel are connected with a bottom plate. The main beam is simple in structure, stable to operate, convenient to machine, low in cost and suitable for being used in cooperation with a high-lift electric hoist perpendicular to the main beam.

Description

A kind of gantry crane girder

Technical field

The invention belongs to crane technical field, particularly to a kind of gantry crane girder.

Background technology

Crane has a wide range of applications at mechanical field, and gantry crane is as lifting the most frequently used in station, harbour Equipment, production and logistics transportation to factory play vital effect;Compared to bridge crane, gantry crane is general There is higher lifting altitude, limit less in vertical direction, for using the middle-size and small-size gantry crane of electric block, electricity Dynamic calabash also has higher lift, and for ensureing stablizing of high-lift electric hoist, the span of electric block running gear is relatively big, Make electric block cannot run to the marginal portion of girder, cause waste;Electric block is vertically arranged with girder, can be effective Evade these drawbacks, but the girder matched more lacks;Therefore it provides a kind of simple in construction, stable, processing side Just, cost is relatively low, is adapted for engagement with the gantry crane girder right and wrong that high-lift electric hoist vertically disposed with girder uses Often it is necessary.

Summary of the invention

The invention aims to overcome the deficiencies in the prior art, and a kind of simple in construction is provided, stable, processing Convenient, cost is relatively low, is adapted for engagement with the gantry crane girder that high-lift electric hoist vertically disposed with girder uses.

The object of the present invention is achieved like this: a kind of gantry crane girder, it includes body beam, described casing Beam section is shaped as the degree of lip-rounding, and the described body beam left and right sides is provided with I-steel, described I-steel respectively with body beam Upper side and downside connect, and are provided with rectangular through-hole in the middle part of described I-steel, and described I-steel upper side connects top Plate, described I-steel downside connects base plate.

The quantity of described I-steel is two.

The I-steel of the described body beam left and right sides is positioned at sustained height.

Described I-steel and body beam left and right sides are provided with gap.

Described I-steel and body beam, I-steel and top board and I-steel are with the connected mode of base plate and weld.

Beneficial effects of the present invention: the body beam that the present invention uses cross section to be the degree of lip-rounding, connects two I-steel, increases electronic The horizontal span of calabash track, it is adaptable to high-lift electric hoist is vertically arranged with girder, top board and base plate ensure that girder is tied Structure is more stable, and rectangular through-hole, on the premise of ensureing girder intensity, effectively alleviates the weight of girder;Present configuration is simple, Stable, easy to process, cost is relatively low, is adapted for engagement with high-lift electric hoist vertically disposed with girder and uses.

Accompanying drawing explanation

Fig. 1 be the present invention a kind of gantry crane girder sectional view.

Fig. 2 is the partial side view of the present invention a kind of gantry crane girder.

In figure: 1, body beam 2, I-steel 3, top board 4, base plate 5, rectangular through-hole.

Detailed description of the invention

The present invention is described further below in conjunction with the accompanying drawings.

Embodiment 1

As depicted in figs. 1 and 2, a kind of gantry crane girder, it includes that body beam 1, described body beam 1 cross sectional shape are The degree of lip-rounding, described body beam 1 left and right sides is provided with I-steel 2, described I-steel 2 respectively with body beam 1 upper side and Downside connects, and is provided with rectangular through-hole 5 in the middle part of described I-steel 2, and described I-steel 2 upper side connects top board 3, institute I-steel 2 downside stated connects base plate 4.

The body beam that the present invention uses cross section to be the degree of lip-rounding, connects two I-steel, increase electric block track horizontal across Degree, it is adaptable to high-lift electric hoist is vertically arranged with girder, and top board and base plate ensure that main beam structure is more stable, rectangle leads to Hole, on the premise of ensureing girder intensity, effectively alleviates the weight of girder;Present configuration is simple, stable, easy to process, Cost is relatively low, is adapted for engagement with high-lift electric hoist vertically disposed with girder and uses.

Embodiment 2

As depicted in figs. 1 and 2, a kind of gantry crane girder, it includes that body beam 1, described body beam 1 cross sectional shape are The degree of lip-rounding, described body beam 1 left and right sides is provided with I-steel 2, described I-steel 2 respectively with body beam 1 upper side and Downside connects, and is provided with rectangular through-hole 5 in the middle part of described I-steel 2, and described I-steel 2 upper side connects top board 3, institute I-steel 2 downside stated connects base plate 4.

The quantity of described I-steel 2 is two;The I-steel 2 of described body beam 1 left and right sides is positioned at sustained height; Described I-steel 2 is provided with gap with body beam 1 left and right sides;Described I-steel 2 and body beam 1, I-steel 2 with Top board 3 and I-steel 2 are with the connected mode of base plate 4 and weld.

The body beam that the present invention uses cross section to be the degree of lip-rounding, connects two I-steel, increase electric block track horizontal across Degree, it is adaptable to high-lift electric hoist is vertically arranged with girder, and top board and base plate ensure that main beam structure is more stable, rectangle leads to Hole, on the premise of ensureing girder intensity, effectively alleviates the weight of girder;Present configuration is simple, stable, easy to process, Cost is relatively low, is adapted for engagement with high-lift electric hoist vertically disposed with girder and uses.
