Abstract

The utility model provides a main beam structure of a crane. The main beam structure is characterized by comprising a linear type main beam body, wherein supporting arms respectively extend out of the left side end and the right side end of the main beam body; and the whole main beam is sunken-shaped; and the supporting arms extend at a certain distance from the side ends of the main beam body to the inclined upper part of the outer side and then extend at a certain distance toward the outer side parallelly. By using the main beam structure, under the condition that the hoisting height of the crane is invariable, the height of a workshop can be reduced, so that a great quantity of construction capitals of the workshop can be reduced, and the production cost is reduced.

Description

The crane girder structure

Technical field

The utility model relates to a kind of crane girder structure, particularly bridging crane main beam structure.

Background technology

Present stage, the girder 1 of crane in bridge type all is to adopt high strength bolt, by master, end carriage connecting panel 3 and end carriage 2 (see figure 1) that links together.Restriction owing to present stage this body structure of girder causes the factory building space utilization unreasonable, has in a disguised form increased construction cost.How construction cost is saved in the effective and reasonable existing factory building space that utilizes, and becomes the target that each producer is pursued.

Summary of the invention

The utility model provides a kind of crane girder structure, and purpose is to solve the prior art problem, provides a kind of and can reduce the main beam structure of factory building height, thereby save a large amount of workshop building funds under the constant situation of crane hoisting height, reduces productive costs.

The utility model technical scheme that adopts of dealing with problems is:

Have linear pattern girder body, this girder body left and right sides end extends upward a hold-down arm respectively, and whole girder is recess.

Described hold-down arm along girder body side laterally oblique upper extend behind the segment distance the parallel segment distance that extends laterally again.

The beneficial effects of the utility model: extend upward hold-down arm at the two ends of girder body in the utility model, make whole girder form recess, when the crane hoisting height is identical, reduce factory building height to greatest extent, save construction cost.

Description of drawings

Fig. 1 is the structural representation that the prior art girder is connected with end carriage;

Fig. 2 is the structural representation of the utility model girder;

Fig. 3 is that embodiment uses constitution diagram;

Fig. 4 is prior art and contrast scheme drawing of the present utility model.

Among the figure: 1. girder, 2. end carriage, 3. master, end carriage connecting panel, 4. girder body, 5. hold-down arm, 6. hold-down arm outside end face.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further details.

Crane girder structure as shown in Figure 2 has linear pattern girder body 4, and these girder body 4 left and right sides ends extend upward a hold-down arm 5 respectively, and whole girder is recess.

In the present embodiment along girder body 4 sides laterally oblique upper extend behind the segment distance again that the parallel segment distance that extends laterally forms hold-down arm 5.In fact the shape of hold-down arm 5 can be any shape that meets the girder requirement of strength, as long as girder integral body presents a recess.

During use, master, end carriage connecting panel 3 are separately fixed at the outside end face 6 of corresponding hold-down arm, screw bolt passes master, end carriage connecting panel 3, end carriage 2 are fixed together the three, girder 1 and end carriage 2 are fixed together, as shown in Figure 3.

Left side among Fig. 4 is the use state of prior art main beam structure, and the right side is the use state of present embodiment middle girder structure.Can find by contrast, under the identical situation of the lifting altitude of hoisting crane, the lifting altitude H2 of the main beam structure among the embodiment is lower than the lifting altitude H1 of prior art middle girder structure, therefore the main beam structure of the invention can reduce the use in space, therefore can suitably reduce factory building height, thereby can save a large amount of workshop building funds, reduce productive costs.The crane hoisting height determines that factory building height is not determined.When guaranteeing the hoisting crane operating needs, lower factory building height as far as possible, just can save a large amount of workshop building funds.

Claims

1. crane girder structure, it is characterized in that: have linear pattern girder body, this girder body left and right sides end extends upward a hold-down arm respectively, and whole girder is recess.

2. the crane girder structure described in claim 1 is characterized in that: described hold-down arm along girder body side laterally oblique upper extend behind the segment distance the parallel segment distance that extends laterally again.
