Transverse telescopic mechanism of highway-sea-railway combined transportation loading and unloading device

Abstract

The invention provides a transverse telescopic mechanism of a highway-sea-railway combined transportation loading and unloading device. The mechanism comprises a telescopic cross beam, a cross beam guide sleeve and a transverse telescopic driving part, wherein the cross beam guide sleeve sleeves the telescopic cross beam, the outer end of the telescopic cross beam is connected with one frame structure of the highway-sea-railway combined transportation loading and unloading device, the outer end of the cross beam guide sleeve is connected with the other frame structure of the highway-sea-railway combined transportation loading and unloading device, the telescopic cross beam slides relative to the cross beam guide sleeve, the two ends of the transverse telescopic driving part are connected with the two frame structures respectively, and walking parts are arranged at the bottoms of the frame structures. The width of the device can be flexibly adjusted, the passing performance and the loading performance of the device are improved, the device can flexibly adapt to various factory environments, and the use requirements are better met.

Description

technical field [0001] The invention relates to the technical field of hoisting and handling equipment, in particular to a transverse telescopic mechanism of a loading and unloading device for intermodal transport of high seas and railways. Background technique [0002] In industrial production, it is usually necessary to transfer large workpieces such as pressure vessels in the factory area. In the prior art, the workpieces are loaded and unloaded and moved in the factory area mainly through special, mobile handling devices. Due to the large width and height of large workpieces, the supporting handling devices also need corresponding width and height dimensions, which makes it difficult for them to pass through some narrow intersections, warehouse entrances, freighter passages, etc. When the large-scale handling device is actually used, it needs to pass through the narrow opening in the unloaded state. For example, when entering a warehouse without a load, the handling devi...
