Jacking main engine assembly and modular self-propelled hydraulic jacking device

Abstract

The invention relates to the technical field of hydraulic jacking equipment, in particular to a jacking main machine assembly. The jacking main machine assembly comprises main machine frames, whereina telescopic mechanism is connected to the upper portion of each main machine frame, a stretching and retracting oil cylinder is arranged between each main machine frame and the corresponding telescopic mechanism, and after the telescopic mechanisms retract and partial main machine frames and partial connecting parts of the telescopic mechanisms are detached, the main machine frames are hinged tothe telescopic mechanisms, and the telescopic mechanisms can be driven to rotate downwards through stretching and retracting of the stretching and retracting oil cylinders. The modular self-propelledhydraulic jacking device comprises at least one set of one jacking main machine assembly, and each set of jacking main machine assembly comprises a left jacking main machine assembly and a right jacking main machine assembly; the two ends of a cross beam assembly are connected to the tops of the telescopic mechanisms of the left jacking main machine assembly and the right jacking main machine assembly correspondingly; and running vehicle assemblies are connected to the cross beam assembly and can move on the cross beam assembly in a self-walking mode. The jacking main machine assembly can be overturned automatically, transportation is convenient, the self-propelled hydraulic jacking device is high in modularization degree; and the running vehicle assemblies are arranged and can transversely move to adjust the position after an object is jacked up.

Description

technical field [0001] The invention relates to the technical field of hydraulic jacking equipment, in particular to a jacking main engine assembly and a modularized self-propelled hydraulic jacking device. Background technique [0002] When disassembling equipment or loading goods in some open places, or when disassembling large equipment in the workshop and encountering the situation that the truss crane does not meet the lifting weight requirements, it is often necessary to rent a car crane or crawler crane to assist in the operation, but the car crane and crawler crane All require a larger work space, such as encountering large-scale equipment and limited space, the work cannot be completed. Therefore, a modular self-propelled hydraulic jacking device with strong versatility and high degree of automation is proposed. Contents of the invention [0003] The object of the present invention is to address the above existing problems and deficiencies, and provide a jacking ...
