Description
Technical field
The utility model relates to a kind of crane portal frame.
Background technology
At present, existing crane portal frame complex structure, is inconvenient to remove and install, can not from a place to moving to another place, and gantry leg is fixed mode, cause portal frame irremovable, therefore have and use the defects such as inconvenient, in addition, its beam mechanism mostly is closed-in construction, crossbeam span ultra-wide when bearing overweight, crossbeam can be sagging, beam deformation is serious, has a strong impact on the unstable properties of hoisting crane.
Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming prior art, provides a kind of crane portal frame, and it can bear larger load, has larger Static stiffness.
The utility model solves the problems of the technologies described above the technical scheme taked: a kind of crane portal frame, and it comprises:
Crossbeam, crossbeam has frame-type body, frame-type body is surrounded by upper beam slab, front beam slab, lower beam slab and rear beam slab, perpendicular gusset, horizontal bar plate and diagonal bar plate is also provided with in frame-type body, one end of perpendicular gusset is fixedly connected on beam slab, the other end of perpendicular gusset is fixedly connected with one end of horizontal bar plate, the other end of horizontal bar plate is fixedly connected with front beam slab, so that frame-type body is divided into two die cavities by perpendicular gusset and horizontal bar plate, on the front beam slab that the two ends of diagonal bar plate are fixedly connected on frame-type body respectively and lower beam slab;
Article two, supporting leg, two supporting legs are connected to the two ends of crossbeam, and two supporting legs are installed with beam vertical and are connected;
Cross bar, cross bar is arranged on the inner side of a wherein supporting leg;
Control cabin, the top of control cabin is connected with crossbeam, and the right-hand member of control cabin is connected on cross bar.
Further, the supporting leg installing cross bar is also provided with cat ladder.
Further, the bottom of supporting leg is provided with road wheel.
After have employed technique scheme, the frame-type body of crossbeam of the present utility model is erected gusset and horizontal bar plate is separated into two die cavities, makes frame-type body have higher rigidity; Diagonal bar plate, lower beam slab and front beam slab form the more stable triangle of structure, can bear larger load, have larger Static stiffness, thus make this crane portal frame across time excessive, avoid holding yielding phenomenon.
Accompanying drawing explanation
Fig. 1 is the structural representation of crane portal frame of the present utility model;
Fig. 2 is the schematic cross-section of crossbeam of the present utility model.
Detailed description of the invention
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail.
As shown in Figure 1, a kind of crane portal frame, it comprises:
Crossbeam 1, crossbeam 1 has frame-type body, frame-type body is surrounded by upper beam slab 11, front beam slab 12, lower beam slab 13 and rear beam slab 14, perpendicular gusset 15, horizontal bar plate 16 and diagonal bar plate 17 is also provided with in frame-type body, one end of perpendicular gusset 15 is fixedly connected on beam slab 11, the other end of perpendicular gusset 15 is fixedly connected with one end of horizontal bar plate 16, the other end of horizontal bar plate 16 is fixedly connected with front beam slab 12, so that frame-type body is divided into two die cavities by perpendicular gusset 15 and horizontal bar plate 16, on the front beam slab 12 that the two ends of diagonal bar plate 17 are fixedly connected on frame-type body respectively and lower beam slab 13;
Article two, supporting leg 2, two supporting legs 2 are connected to the two ends of crossbeam 1, and two supporting legs 2 are connected with crossbeam 1 at right angle setting;
Cross bar 6, cross bar 6 is arranged on the inner side of a wherein supporting leg 2;
Control cabin 3, the top of control cabin 3 is connected with crossbeam 1, and the right-hand member of control cabin 3 is connected on cross bar 6.
The supporting leg 2 installing cross bar 6 is also provided with cat ladder 4.
The bottom of supporting leg 2 is provided with road wheel.
Principle of work of the present utility model is as follows:
The frame-type body of crossbeam 1 of the present utility model is erected gusset 15 and horizontal bar plate 16 is separated into two die cavities, makes frame-type body have higher rigidity; Diagonal bar plate 17, lower beam slab 13 form the more stable triangle of structure with front beam slab 12, can bear larger load, have larger Static stiffness, thus make this crane portal frame across time excessive, avoid holding yielding phenomenon.
Above-described specific embodiment; technical matters, technical scheme and beneficial effect that the utility model solves are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
