Abstract

The invention relates to a 6,400-ton hydraulic pressure compound crane, belonging to the machinery field. The 6400ton hydraulic pressure compound crane is composed of a steel frame structure, an electro-hydraulic power system and a computer control system, and is characterized in that the steel frame structure comprises four towers, a main beam, a connecting beam and a slippage bearing beam, wherein the tower comprises a base, standard knots and a top knob device, a plurality of overlapped standard knots are arranged between the base and the top knob device, the slippage bearing beam is arranged on the top knob device, the main beam is connected to the slippage bearing beam by a flexible hinge, and the connecting beam is connected between the towers. The 6400-ton hydraulic pressure compound crane adopts the computer control system for operation, requires few operators, can achieve accurate, stable and safe control, has the advantages when being applied to extra-large superheavy equipment and integral hoisting of components, and has important significances on reducing resource wastes and improving working efficiency.

Description

technical field [0001] The invention belongs to the field of machinery, and is mainly used for hoisting super-large and overweight equipment in the construction of large-scale coal chemical and petrochemical projects. efficiency. [0002] Scope of application: hoisting of oversized and overweight equipment, lifting of large and heavy components in industrial construction. Background technique [0003] On December 23, 2008, the first 160,000 tons / year coal-based synthetic oil demonstration project in Shanxi Lu'an with independent intellectual property rights in China officially produced oil. On March 16, 2009, Inner Mongolia Yitai 160,000 tons / year coal The oil production project officially produced oil. This means that my country has fully utilized its own core technology to realize coal-to-oil, marking the first barrel of coal-based synthetic oil produced by the national "863" high-tech project and the knowledge innovation project of the Chinese Academy of Sciences,...
