Abstract

The utility model relates to a double-beam portal crane turnover structure. The double-beam portal crane turnover structure comprises a main beam assembly and two support legs for supporting the main beam, a walking mechanism falling on a rail is mounted at the bottom of each support leg, the main beam assembly is in a double-beam structure, and an upward walking trolley and a downward walking trolley which do not interfere with each other are arranged on the double main beam assembly. The double-beam portal crane turnover structure is characterized in that a double main lifting mechanism is arranged on the upward walking trolley, and a main lifting mechanism and a sub lifting mechanism are arranged on the downward walking trolley at the same time. In the process of lifting sections of a large-scale ship body in the ship building industry, the main lifting mechanism of the upward walking trolley and the main lifting mechanism of the downward walking trolley can be used to achieve the purpose of lifting the sections of the large-scale ship body, and at the same time, the sub lifting mechanism can be used to achieve the turnover of the sections of the ship body in auxiliary mode. In addition, if the mass of a to-be-lifted object is quite small, the sub lifting mechanism can be directly used to lift the object to avoid unnecessary energy consumption.

Description

A kind of double girder gantry crane overturn structure
Technical field
The utility model relates to a kind of double girder gantry crane, particularly a kind of double girder gantry crane overturn structure.
Background technology
Transfer crane is a kind of distortion of crane in bridge type, and its metal construction is door-shaped frame, and two legs are installed under the support main beam, can directly walk at the ground orbit of flates, and the girder two ends can have overhanging cantilever beam.Transfer crane has the characteristics such as the utilization of area rate is high, scope of work large, it is wide to adapt to, highly versatile, is used widely in the goods yard, harbour.
Transfer crane is divided into single girder portal crane and two girder portal crane by the girder form, and the two girder portal cranes of most adopt upper and lower walking vehicle structure, and two lifting assemblies are set on the upper walking dolly.A lifting assembly is set on the lower walking dolly.This kind structure can hoisting large-size body section, but comparatively inconvenience when needs overturn to body section is used to be subject to certain limitation.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of double girder gantry crane overturn structure of lifting and overturning can realized.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of double girder gantry crane overturn structure, two supporting legs that comprise girder and supporting main beam, the supporting leg bottom is equipped with traveling gear in orbit, described girder is two main beam structures, is provided with upper walking dolly and the lower walking dolly of mutually noninterfere on the described pair of girder; Its innovative point is: described upper walking dolly is provided with two main hoisting mechanisms, is provided with simultaneously main hoisting mechanism and auxiliary hoisting mechanism on the described lower walking dolly.
The utility model has the advantage of: when ship building industry hoisting large-size body section, can utilize the main hoisting mechanism of upper and lower walking dolly to realize, simultaneously, can be by the auxiliary upset that realizes body section of auxiliary hoisting mechanism.In addition, if the article quality of lifting is less, also can directly adopt auxiliary hoisting mechanism to lift, avoid unnecessary energy resource consumption.
Description of drawings
Fig. 1 is the utility model double girder gantry crane overturn structure schematic diagram.
The specific embodiment
As shown in Figure 1, comprise girder 1, supporting leg 2, traveling gear 3, upper walking dolly 4, lower walking dolly 5, main hoisting mechanism 6, main hoisting mechanism 7, main hoisting mechanism 8 and auxiliary hoisting mechanism 9.
The two ends of above-mentioned girder 1 arrange the supporting leg 2 of supporting main beam 1, supporting leg 2 rigid legs of an end wherein, and the other end is flexible leg.Supporting leg 2 bottoms are equipped with traveling gear 3 in orbit.
Girder 1 is two main beam structures, in inboard and the outside of two girders interior guide rail and outer guide is installed respectively, and interior guide rail is provided with lower walking dolly 5, and walking dolly 4 is set on the outer guide.Two main hoisting mechanisms 6,7 are installed on the upper walking dolly 4, and main hoisting mechanism 6,7 is arranged on the both sides of walking dolly 4, is provided with simultaneously main hoisting mechanism 8 and auxiliary hoisting mechanism 9 on the lower walking dolly 5.In the present embodiment, main hoisting mechanism 6,7 hoisting capacity are 170 tons, and the hoisting capacity of main hoisting mechanism 8 is 250 tons, and the hoisting capacity of auxiliary hoisting mechanism 9 is 20 tons.

Claims (1)
