Resonance resistance type crane double-beam conveying device

Abstract

The invention discloses a resonance resistance type crane double-beam conveying device. The device comprises a first cross beam; a speed reducing motor is arranged on one side of one end of the first cross beam, and is connected with a first gear through a shaft; a second cross beam is arranged on the upper side of the first cross beam; a third cross beam is arranged on the upper side of the second cross beam; first rolling shafts are uniformly arranged between the first cross beam and the second cross beam from left to right; second rolling shafts are uniformly arranged between the second cross beam and the third cross beam from left to right; the first rolling shafts and the second rolling shafts penetrate through rotating shafts; multiple first connecting frames are arranged between the first cross beam and the second cross beam; multiple second connecting frames are arranged between the second cross beam and the third cross beam; and the first connecting frames and the second connecting frames are staggered and spaced. The resonance resistance type crane double-beam conveying device has the advantages of convenience for installation, easiness in maintenance, convenience for fixation, simple structure and high reliability.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to an anti-resonance double-girder conveying device for cranes. Background technique [0002] In the production process of the box-type main girder of the bridge and gantry cranes, the main girder of the crane needs to be welded. In the workshop of the assembly line, the main girder of the crane needs to be transported. Now in the industry, lifting and moving are often used. This method not only wastes manpower and material resources, but also inaccurately moves the position and is inefficient. At the same time, it is easy to cause damage to the main girder, and there are many problems in some transmission equipment transmission. In the case of moving, the main girder will collide. At the same time, in the process of moving, because the main girder is a steel structure and the weight is heavy, it is easy to slip the transmission roller during the conveying process, which is not condu...

Problems solved by technology

[0002] In the production process of the box-type main girder of the bridge and gantry cranes, the main girder of the crane needs to be welded. In the workshop of the assembly line, the main girder of the crane needs to be transported. Now in the industry, lifting and moving are often used. This method not only wastes manpower and material resources, but also inaccurately moves the position and is inefficient. At the same time, it is easy to cause damage to the main girder, and there are many problems in some transmission equipment transmission. In the case of moving, the main girder will collide. At the same time, in the process of moving, because the main girder is a steel structure and the weight is heavy, it is easy to slip the transmission roller during the conveying process, which is not conducive to conveying; moreover, the existing conveying The device can only realize the transmission of a single beam. In large-scale production sites, this kind of conveying device that can only transport a single beam can no longer meet the production needs.

[0003] Chinese patent CN204896501U discloses a chain-type full-drive crane double-girder conveying platform, which includes a beam A, and one side of one end of the beam A is provided with a geared motor, and the geared motor is connected to a first gear through a shaft. The upper side of the beam A is provided with the beam B, and the upper side of the beam B is provided with the beam C, and the first rollers are uniformly arranged between the beam A and the beam B from left to right, and the beam B and the beam C There are second rollers evenly arranged between them, the first roller and the second roller pass through a rotating shaft, one end of the rotating shaft is provided with a second gear, and the upper side of the second gear is provided There is a third gear, the first gear is connected with the adjacent third gear through a chain, and the adjacent second gear and the adjacent third gear are connected through a chain; the invention has the advantages of easy installation and maintenance , convenient fixing, and simple structure, but the invention has low structural strength in the actual application process, and the situation of resonance jumping between parallel tracks is easy to appear, which needs to be improved urgently
