Description

A kind of crane girder inner supporting structure
Technical field
The utility model belongs to hoisting crane technical field, is specifically related to a kind of crane girder inside
Supporting construction.
Background technology
Hoisting crane is widely used in industrial and mining enterprises, it is the requisite lifting appliance of production site, the girder of hoisting crane, it is the core component bearing body weight, its structure directly affects the serviceability of hoisting crane, and in general the oad of hoisting crane is conditional, how to reduce under the heavy prerequisite of beam, ensureing intensity, the rigidity of crane girder, is long-standing technical barrier.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides one can alleviate girder weight, can ensure again the crane girder inner supporting structure of girder strength and stiffness.
The technical solution of the utility model is achieved in that a kind of crane girder inner supporting structure, comprise beam casing, be arranged on the crossbeam on beam casing top, the top of described beam casing is provided with opening, beam box house is provided with dividing plate, and be fixedly connected with beam casing diapire bottom dividing plate, dividing plate sidepiece is fixedly connected with beam wall box, dividing plate top is fixedly connected with the bottom of crossbeam, and the bottom of described dividing plate is provided with opening.
The first half shape of described dividing plate is isosceles trapezoid, and lower part shape is rectangle.
The thickness of described dividing plate is not more than 6 millimeters.
The quantity of described dividing plate is at least 3, and the distance of adjacent 2 dividing plates is not more than 500 millimeters.
The height of the lower part of described dividing plate is identical with the height of beam casing.
The cross sectional shape of described beam casing is rectangle.
Web is provided with between four sides that the top of described beam casing four sides is corresponding to crossbeam.
The utility model has following beneficial effect: the weight not only reducing girder, and the strength and stiffness that ensure that girder; Save material, decrease input cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the front view of dividing plate.
Fig. 3 is the structural representation of dividing plate.
Detailed description of the invention
As shown in Figure 1, 2, 3, a kind of crane girder inner supporting structure, comprise beam casing 1, be arranged on the crossbeam 2 on beam casing 1 top, the top of described beam casing 1 is provided with opening, and beam casing 1 inside is provided with dividing plate 4, be fixedly connected with beam casing 1 diapire bottom dividing plate 4, dividing plate 4 sidepiece is fixedly connected with beam casing 1 sidewall, and dividing plate 4 top is fixedly connected with the bottom of crossbeam 2, and the bottom of described dividing plate 4 is provided with opening 5.The first half shape of described dividing plate 4 is isosceles trapezoid, and lower part shape is rectangle.The thickness of described dividing plate 4 is not more than 6 millimeters.The quantity of described dividing plate 4 is at least 3, and the distance of adjacent 2 dividing plates is not more than 500 millimeters.The height of the lower part of described dividing plate 4 is identical with the height of beam casing 1.The cross sectional shape of described beam casing 1 is rectangle.Web 3 is provided with between four sides that the top of described beam casing 1 four sides is corresponding to crossbeam 2.
The utility model is in use: described structure is turned over turnback, beam casing 1 is upper, crossbeam 2 under, crossbeam 2 is fixed up by bracing frame and ground, and beam casing 1 travels crane carriage, the form that this main beam structure adopts beam casing 1 and dividing plate 4 to combine, and the opening 5 that dividing plate 4 is arranged, the setting of the height of the lower part of the shape that dividing plate 4 adopts and dividing plate, this structure not only alleviates the weight of girder, save material, and ensure that the strength and stiffness of girder.
