Abstract

The invention relates to a single girder overhead crane, which comprises a girder frame, wherein each upper end of two sides of the girder frame is fixedly connected with an end girder guide rail separately, each end girder guide rail is provided with an end girder; the two ends of a main girder are fixedly connected with two end girders separately; the main girder is further provided with a hoist trolley; the end girders are rectangular; the bottom of each end of the main girder is fixedly connected with the top of each end girder; the cross section of the middle part of the main girder is I-shaped; the hoist trolley is U-shaped and mounted on the base of the main girder. By adopting the method in which the main girder is fixedly connected with the top of each end girder, the structure of the single girder overhead crane is more stable, the manufacturing technique is simple and the end girders lift the main girder, thus the lift height of goods is effectively increased and the space of a factory plant is sufficiently utilized.

Description

A kind of single beam type hoisting crane
technical field:
The present invention relates to elevator machinery field, particularly a kind of single beam type hoisting crane.
background technology:
Existing single beam type hoisting crane is generally girder two ends and merges the structure on end carriage, and hoist crab is to be U font to be hung on girder bottom.Make like this bottom of hoist crab and the close together between ground, hoisting objects height is lower, and factory building must be built to obtain the higher large-sized object of just slinging, and has strengthened to a certain extent the input cost of factory building, and has reduced the degree of utilization in factory building space.And such single beam type hoisting crane manufacturing process is complicated, need to use a large amount of welding processs and structural stability lower, hoisting weight is also lower.
summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and a kind of single beam type hoisting crane is provided, and has well solved existing single beam type crane loading height low, and factory building space availability ratio is low, and manufacturing process is complicated, structural unstable problem.
Technology solution of the present invention is as follows:
A kind of single beam type hoisting crane, comprise roof beam structure, upper end, described roof beam structure both sides is fixedly connected with respectively a butt beam guide rail, on described end carriage guide rail, end carriage is installed, the two ends of girder are fixedly connected on respectively on 2 end carriages, and hoist crab is also installed on girder, described end carriage is cuboid, the bottom at described girder two ends is fixedly connected on the top of end carriage, and in described girder, cross section is I-shape, and hoist crab is Qian font and is erected on girder base.The mode that girder is fixedly connected on to end carriage top not only makes the structure of single beam type hoisting crane more stable, and manufacturing process is simple, and end carriage raises girder, thereby effectively raise the sling height of article, utilized fully the space of factory building; In girder, cross section becomes I-shape to make girder base just can be called the track of hoist crab, thereby the hoist crab that is Qian font can be erected on girder base, the distance on hoist crab bottom and ground is increased, the space that further actv. utilization plays factory building.
As preferably, the cross section at girder two ends is isosceles trapezoid.Make like this girder two ends more tight with being fixedly connected with of end carriage, structure is more stable.
As preferably, on the side of hoist crab, motor is installed.
As preferably, girder top one side is fixedly connected with the electric wire hack lever that hangs hoist crab electric wire.Electric wire hack lever is arranged on to girder top, has further saved space, and make arranging of circuit more succinct.
Beneficial effect of the present invention is:
1, the mode that the present invention is fixedly connected on end carriage top by girder not only makes the structure of single beam type hoisting crane more stable, and manufacturing process is simple, and end carriage raises girder, thereby effectively raise the sling height of article, utilized fully the space of factory building; In girder, cross section becomes I-shape to make girder base just can be called the track of hoist crab, thereby the hoist crab that is Qian font can be erected on girder base, the distance on hoist crab bottom and ground is increased, the space that further actv. utilization plays factory building;
2, the cross section at girder of the present invention two ends is isosceles trapezoid, makes girder two ends more tight with being fixedly connected with of end carriage, and structure is more stable;
3, the present invention is arranged on girder top by electric wire hack lever, has further saved space, and makes arranging of circuit more succinct.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Fig. 2 is birds-eye view of the present invention;
Fig. 3 is lateral plan of the present invention;
In figure: girder 1; End carriage 2; Hoist crab 3; Motor 4; Electric wire hack lever 5.
the specific embodiment:
Embodiment: a kind of single beam type hoisting crane as shown in Figure 1, Figure 2, Figure 3 shows, comprise roof beam structure, upper end, roof beam structure both sides is fixedly connected with respectively a butt beam guide rail, end carriage 2 is installed on end carriage guide rail, and the two ends of girder 1 are fixedly connected on respectively on 2 end carriages 2, and hoist crab 3 is also installed on girder 1, end carriage 2 is cuboid, the bottom at girder 1 two ends is fixedly connected on the top of end carriage 2, and in girder 1, cross section is I-shape, and hoist crab 3 is Qian font and is erected on girder 1 base.
The cross section at girder 1 two ends is isosceles trapezoid.
Motor 4 is installed on the side of hoist crab 3.
Girder 1 top one side is fixedly connected with the electric wire hack lever 5 that hangs hoist crab 3 electric wires.
The foregoing is only preferred embodiment of the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, should belong to the scope of protection of the invention.
