Abstract
The utility model provides a dual-track single main beam of an electric gourd crane, which comprises an upper wing panel arranged on the upper end, a pair of ventral shields which are vertically arranged on both lower ends of the upper wing panel, and inverted T-shaped orbits which are respectively arranged on the lower end of each of the vertical shields. The technical proposal of the utility model further comprises an upper wing panel stiffening rib is arranged on the undersurface of the upper wing panel, and vertical shield stiffening ribs are respectively arranged on the inner sides of the two vertical shields. The dual-track single main beam adopts a groove shape beam body and arranges a dual-track orbit on the lower end of the groove shape beam body, thereby forming the dual-track single main beam of an electric gourd crane, when in use, a lifting gourd is arranged in the groove shape beam body above the orbit, which reduces the distance between a lifting hook of the lifting gourd and the upper wing panel of the main beam in maximum, thereby effectively increasing the lifting height of the crane under the condition that the height of a building or a supporting leg of the crane is unchanged, and since the lifting gourd is arranged in the groove shape beam body, the lifting gourd is avoided to be caught in rain when the crane works in open air, thereby guaranteeing the 24-hour use of the crane.
Description
Technical field
The utility model relates to electric block formula hoisting crane, is specifically related to a kind of electric block formula hoisting crane double track list girder.
Background technology
At present, the girder of electric block formula hoisting crane mostly is the single track main beam structure that the inverted T-shaped track is set in beam body lower end, and hoist crane is suspended on the monorail track edge of a wing and is used for lifting operation.Above-mentioned single track main beam structure is because the girder upper flange is bigger to hoist crane suspension hook distance, sling height is low under the certain condition of building or hoisting crane height of landing leg, and under hoisting crane was in open-air atmosphere, hoist crane was subject to drench with rain, and is unwell to all-weather service.
Summary of the invention
The purpose of this utility model is at the problems referred to above, a kind of electric block formula hoisting crane double track list girder is provided, this double track list girder is under the certain condition of building or height of landing leg, can effectively increase the sling height of hoisting crane, and can avoid hoist crane to be drenched with rain in the open under the environment, guarantee the hoisting crane all-weather service.
The technical scheme that realizes above-mentioned purpose is: a kind of electric block formula hoisting crane double track list girder, it is by the upper flange that places the upper end and place below the upper flange a pair of perpendicular of two ends to put web and place the inverted T-shaped track of each web lower end to form respectively.
The technical solution of the utility model also comprises: be provided with the upper flange ribbed stiffener below upper flange, be respectively arranged with the web ribbed stiffener in the inboard of two webs.
The utility model adopts the trough girder body and in the lower end of trough girder body double-rail track is set, and the double track list girder of formation electric block formula hoisting crane, hoist crane places in the trough girder body of track top during use, hoist crane suspension hook and girder upper flange spacing are dwindled to greatest extent, thereby under the certain condition of building or hoisting crane height of landing leg, effectively increase the sling height of hoisting crane, and because hoist crane places in the trough girder body, hoist crane is drenched with rain in the time of can avoiding hoisting crane operation in the open, guarantees the all-weather service of hoisting crane.
Description of drawings
Fig. 1 is an example structure scheme drawing of this electric block formula hoisting crane double track list girder;
Fig. 2 is another example structure scheme drawing of this electric block formula hoisting crane double track list girder.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing, this electric block formula hoisting crane double track list girder has the upper flange 1 that places the upper end, two ends below upper flange are provided with a pair of perpendicular web of putting 2, lower end at each web is oppositely arranged inverted T-shaped track 3 respectively, below upper flange, be provided with upper flange ribbed stiffener 4, be respectively arranged with web ribbed stiffener 5 in the inboard of two webs 2.
When the utility model is specifically implemented, adopt the assembly welding technique moulding.Inverted T-shaped track 3 can adopt the part I-beam section, by the lower end of butt welding at web 2.Web 2 upper ends of accompanying drawing 1 embodiment process into 90 ° interior bending, and bending is connected with upper flange by welding with the compound back of upper flange in this.Accompanying drawing 2 embodiment then directly connect by the upper end of web 2 and following being weldingly connected of upper flange 1.
Upper flange ribbed stiffener 4 of the present utility model and web ribbed stiffener 5 are provided with in the trough girder body at regular intervals, and when specifically implementing, the two side ends of upper flange ribbed stiffener connects with the web ribbed stiffener butt welding of corresponding side respectively.
Claims (2)
1, a kind of electric block formula hoisting crane double track list girder is characterized in that: it is by the upper flange (1) that places the upper end and place a pair of perpendicular of the following two ends of upper flange (1) to put web (2) and place the inverted T-shaped track (3) of each web lower end to form respectively.
2, electric block formula hoisting crane double track list girder according to claim 1 is characterized in that: be provided with upper flange ribbed stiffener (4) below upper flange (1), be respectively arranged with web ribbed stiffener (5) in the inboard of two webs (2).
