The crane girder can realize the running of upper and lower trolleys through the auxiliary girder, has a compact structure, saves the manufacturing cost of a crane and reduces the requirement on the height of a workshop.

Description

Crane girder
Technical field
The utility model relates to the hoisting crane technical field, relates in particular to a kind of girder of hoisting crane.
Background technology
Hoisting crane all is the lifting work of being carried out weight by a trolley travelling on a secondary girder usually, but two dollies of the need of work of some occasion are coordinated just can finish one on the other mutually, arrange simultaneously on a secondary girder that like this two dollies do not realize, therefore need two dollies of two secondary girders finish this work jointly.For example, in the steel ladle hoisting process of steelworks, hoisting crane not only will be finished the action of slinging of steel ladle, the upset that also will realize steel ladle is poured molten steel in transport trolley or the die cavity sequence, these actions can't realize on a dolly simultaneously, are therefore just finished jointly by two hoisting cranes arranging up and down.Two hoisting cranes just have two secondary girders and two dollies, and this just needs factory building height to raise, and has increased the design cost and the building cost of factory building.
The utility model content
Technical problem to be solved in the utility model is: a kind of crane girder is provided, makes a secondary girder can realize up and down two trolley travellings simultaneously, and compact conformation, the manufacturing cost of having saved hoisting crane has reduced the requirement for height of factory building.
For solving the problems of the technologies described above, the technical solution of the utility model is: crane girder comprises the girder upper cover plate that is used to install the main carriage track; Main web that is oppositely arranged and secondary web, described main web and secondary web are fixedly installed on the described girder upper cover plate respectively and perpendicular to described girder upper cover plate; With the relative girder lower cover in described girder upper cover plate position, described girder lower cover is connected between described main web and the secondary web; Described girder also comprises the attaching beam that is used for secondary carriage walking, and described attaching beam is fixedly installed on the described main web and is positioned at described girder lower cover one end.
As a kind of improvement, described attaching beam comprises the attaching beam upper cover plate that is used to install secondary trolley track, and described attaching beam upper cover plate is fixedly installed on the described main web and perpendicular to described main web; Attaching beam lower cover, described attaching beam lower cover are fixedly installed on the described main web and are relative with described attaching beam upper cover plate position; Attaching beam web, described attaching beam web are connected between described attaching beam upper cover plate and the attaching beam lower cover and are positioned at the below of described secondary trolley track.
After having adopted technique scheme, the beneficial effects of the utility model are: owing to be provided with attaching beam in the side of crane girder, make that the girder of a hoisting crane can be simultaneously for two carriage walkings of arranging up and down, compare for the structure of independent carriage walking respectively with two traditional girders, structure is compact more, save a girder, saved material, reduced the manufacturing cost of hoisting crane; In the side of girder the attaching beam that is used for carriage walking is installed simultaneously, has been realized two combination actions that hoisting crane could be realized, reduced the requirement for height of factory building with the installing space of a hoisting crane.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the running condition figure of the utility model embodiment;
Among the figure: 1, girder upper cover plate, 2, main web, 3, secondary web, 4, the girder lower cover, 5, the main carriage track, 6, attaching beam, 61, the attaching beam upper cover plate, 62, the attaching beam web, 63, the attaching beam lower cover, 7, secondary trolley track, 8, main carriage, 9, secondary dolly.
The specific embodiment
As shown in Figure 1, a kind of crane girder comprises the box-structure that is surrounded by girder upper cover plate 1, main web 2, secondary web 3 and girder lower cover 4, and the side of girder is provided with attaching beam 6.Wherein, described girder upper cover plate 1 is used to install main carriage track 5; Described main web 2 and secondary web 3 are oppositely arranged, and described main web 2 and secondary web 3 are fixedly installed on the described girder upper cover plate 1 respectively and perpendicular to described girder upper cover plate 1; Described girder lower cover 4 is relative with the position of girder upper cover plate 1, and described girder lower cover 4 is connected between described main web 2 and the secondary web 3; Described attaching beam 6 is used for secondary dolly 9 walkings, and described attaching beam 6 is fixedly installed on the described main web 2 and is positioned at described girder lower cover 4 one ends, and described attaching beam 6 is consistent with the bearing of trend of girder upper cover plate 1.
Described attaching beam 6 mainly comprises attaching beam upper cover plate 61, attaching beam lower cover 63 and attaching beam web 62.Described attaching beam upper cover plate 61 is used to install secondary trolley track 7, and described attaching beam upper cover plate 61 is fixedly installed on the described main web 2 and perpendicular to described main web 2; Described attaching beam lower cover 63 is fixedly installed on the described main web 2 and is relative with described attaching beam upper cover plate 61 positions; Described attaching beam web 62 is connected between described attaching beam upper cover plate 61 and the attaching beam lower cover 63 and is positioned at the below of described secondary trolley track 7.
Its principle of work is as follows:
As shown in Figure 2, girder mounted in pairs during use, form a secondary main beam structure, on the girder upper cover plate 1 above the girder, be installed with main carriage track 5, walk back and forth for main carriage 8, be positioned at girder lower cover 4 one ends in main web 2 sides of girder and be provided with attaching beam 6, be installed with secondary trolley track 7 on the attaching beam 6, walk back and forth for secondary dolly 9, the intensity of attaching beam 6 can be designed according to the weight that secondary dolly 9 is lifted,, the form of welded steel structure can be adopted if the dynamics of secondary dolly 9 liftings is little, for example lifting steel ladle is mainly realized by main carriage 8, and rotary movement is realized by secondary dolly 9, so the relative main carriage of the power that secondary dolly 9 bears 8 is much smaller, so attaching beam 6 can be by attaching beam upper cover plate 61, attaching beam lower cover 63 and attaching beam web 62 are welded, this welded steel structure can satisfy the required load of upset moment of torsion of steel ladle fully, during work, main carriage 8 is realized lifting, and secondary dolly 9 is realized upset, two dollies are coordinated mutually, finish sequence jointly.This girder is incorporated into the girder of two hoisting cranes together, has saved two girders, has saved material, reduced productive costs, simultaneously, have only the height that satisfies a hoisting crane of installation to implement, reduced the design cost and the building cost of factory building requirement on height of workshop.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
