Description

Technical Field

[0001] The utility model relates to the technical field of mechanical design, in particular to a hydraulic motor lifting beam hoisting device. Background Art

[0002] The lifting beam is a piece of equipment used to lift and transport goods via a monorail crane. It has the advantages of large lifting load, flexible transportation, small space occupation and high transportation efficiency. It is widely used in tunnels, mines and other occasions.

[0003] There are two main ways to lift the lifting beam of the monorail crane locomotive that are widely used at present: one is to use the hydraulic hoist on the main beam to lift and lower through the cross beam, which is suitable for straight and high tunnel sections; the other is to use the hydraulic cylinder inside the frame beam to extend and retract to achieve lowering and lifting, which is suitable for short tunnels. Both of these lifting methods can only be used for one type of tunnel, and the lifting points of these two lifting methods are fixed or manually adjusted by changing the sprocket position. The adjustment position is limited, and it is also difficult to make the lifting chain perpendicular to the heavy object for lifting. Utility Model Content
