Problems solved by technology

[0002] Cranes are widely used in the field of machinery. As the most commonly used lifting equipment in stations and docks, gantry cranes play a vital role in factory production and logistics transportation; compared with bridge cranes, gantry cranes Generally, it has a higher lifting height and is less restricted in the vertical direction. For small and medium-sized gantry cranes that use electric hoists, the electric hoist also has a higher head. In order to ensure the stability of the high-lift electric hoist, the electric hoist travel device The large span makes the electric hoist unable to run to the edge of the main girder, resulting in waste; setting the electric hoist perpendicular to the main girder can effectively avoid these disadvantages, but there is a lack of matching main girders; therefore, providing a The structure is simple, the operation is stable, the processing is convenient, and the cost is low. It is very necessary to use the main beam of the gantry crane which is suitable for the high-lift electric hoist installed vertically with the main beam.

Embodiment 1

[0015] Such as figure 1 and figure 2 As shown, a main girder for a gantry crane includes a box girder 1, the cross-sectional shape of the box girder 1 is a mouth shape, and the left and right sides of the box girder 1 are provided with I-beams 2, so The I-beam 2 is respectively connected to the upper side and the lower side of the box girder 1, the middle part of the I-beam 2 is provided with a rectangular through hole 5, the upper side of the I-beam 2 is connected to a top plate 3, and the The lower side of the I-beam 2 is connected with a bottom plate 4.

[0016] The invention adopts a box beam with a mouth-shaped cross section, connects two I-beams, increases the transverse span of the electric hoist track, and is suitable for the vertical arrangement of the high-lift electric hoist and the main beam. The top plate and the bottom plate ensure that the main beam structure is more stable, rectangular The through hole can effectively reduce the weight of the main beam under...

Embodiment 2

[0018] Such as figure 1 and figure 2 As shown, a main girder for a gantry crane includes a box girder 1, the cross-sectional shape of the box girder 1 is a mouth shape, and the left and right sides of the box girder 1 are provided with I-beams 2, so The I-beam 2 is respectively connected to the upper side and the lower side of the box girder 1, the middle part of the I-beam 2 is provided with a rectangular through hole 5, the upper side of the I-beam 2 is connected to a top plate 3, and the The lower side of the I-beam 2 is connected with a bottom plate 4.

[0019] The number of the I-beam 2 is two; the I-beam 2 on the left and right sides of the box girder 1 is located at the same height; the I-beam 2 and the left and right sides of the box girder 1 are all provided with Gap: The connection modes of the I-beam 2 and the box girder 1, the I-beam 2 and the top plate 3, and the I-beam 2 and the bottom plate 4 are welding.

Abstract

The invention relates to a main beam for a portal crane. The main beam comprises a box beam and is characterized in that the cross section of the box beam is square, H-shaped steel is arranged on the left side and the right side of the box beam and connected with the upper side face and the lower side face of the box beam, the middle portion of the H-shaped steel is provided with a rectangular through hole, the upper side faces of the H-shaped steel are connected with a top plate, and the lower side faces of the H-shaped steel are connected with a bottom plate. The main beam is simple in structure, stable to operate, convenient to machine, low in cost and suitable for being used in cooperation with a high-lift electric hoist perpendicular to the main beam.
