Abstract

The utility model discloses a large double-beam box-type gantry crane which comprises support legs and a main beam supported by the support legs, wherein each support leg comprises a lower section support leg arranged under the main beam, and an upper section support leg arranged above the main beam; and a reinforcing rod piece used for enhancing the strength and the rigidity of the main beam is connected between the upper part of each upper section support leg arranged above the main beam and the main beam. After the structure is adopted by the large double-beam box-type gantry crane, the reinforcing rod piece used for enhancing the strength and the rigidity of the main beam is connected between the upper part of each upper section support leg arranged above the main beam and the main beam, so that the thickness of the box-type main beam is not needed to be increased, the steel is saved, and the production cost is further lowered.

Description

The box gauntry crane of large-scale twin beams
Technical field
The utility model relates to a kind of gauntry crane, especially relates to the box gauntry crane of a kind of large-scale twin beams.
Background technology
In the past at the outdoor box gauntry crane of twin beams of doing industry, mainly comprise supporting leg, girder, dolly, cart and electric etc., the hoisting capacity majority is all below 32 tons, and the span majority is all below 30 meters, and beam length is general all at 45 meters.The box gauntry crane of twin beams of large-tonnage (above 32 tons), large span (span is above 30 meters), girder long (beam length is above 45 meters) girder steady when guaranteeing the hoisting crane operation; Usually need increase the thickness of box girder, to improve the strength and stiffness of girder.But when improving the strength and stiffness of girder, can increase the manufacturing cost of the box gauntry crane of twin beams, the waste great deal of steel by the thickness that increases box girder.
The utility model content
The technical matters that the utility model will solve provide a kind of when hoisting crane moves girder operate steadily and need not increase box girder thickness and then save the box gauntry crane of large-scale twin beams that steel reduce manufacturing cost.
For solving the problems of the technologies described above; The box gauntry crane of a kind of large-scale twin beams of the utility model; Comprise supporting leg and the girder that supports by supporting leg; Said supporting leg comprises hypomere supporting leg that is positioned at said girder below and the epimere supporting leg that is positioned at the girder top, is connected with the reinforcing member that is used to strengthen the girder strength and stiffness between said top and the girder at the epimere supporting leg above the girder.
Adopt the box gauntry crane of large-scale twin beams of said structure; Owing between the top of the epimere supporting leg above the girder and girder, be connected with the reinforcing member that is used to strengthen the girder strength and stiffness, thereby need not increase box girder thickness and then save steel and reduced manufacturing cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done to specify further.
Fig. 1 is the main TV structure scheme drawing of the box gauntry crane of the large-scale twin beams of the utility model.
Fig. 2 is the plan structure scheme drawing of the box gauntry crane of the large-scale twin beams of the utility model.
The specific embodiment
Referring to Fig. 1, Fig. 2; The box gauntry crane of the large-scale twin beams of the utility model; Comprise supporting leg 1 and the girder 2 that supports by supporting leg 1; Said supporting leg 1 comprises hypomere supporting leg 3 that is positioned at said girder 2 belows and the epimere supporting leg 4 that is positioned at girder 2 tops, is connected with the reinforcing member 5 that is used to strengthen the girder strength and stiffness between said top and the girder 2 at the epimere supporting leg 4 above the girder 2.

Claims (1)

1. box gauntry crane of large-scale twin beams; Comprise supporting leg and the girder that supports by supporting leg; Said supporting leg comprises and it is characterized in that hypomere supporting leg that is positioned at said girder below and the epimere supporting leg that is positioned at the girder top: be connected with the reinforcing member that is used to strengthen the girder strength and stiffness between said top and the girder at the epimere supporting leg above the girder.
