A special combined hydraulic lifting hoist for scientific research ships

Abstract

The invention discloses a combined hydraulic lifting and hoisting machine for a scientific research ship. Two sets of a base, a rotating box, a rotating shaft, a servo motor, a lifting arm and a lifting cylinder are arranged in parallel. Each of the two lifting arms includes a main lifting arm which is rotatably connected with the corresponding rotating box. Two auxiliary lifting arms which are inflexible connection with the corresponding main lifting arms are respectively arranged along the extension directions of the two main lifting arms. A push-and-pull oil cylinder used for driving eachauxiliary lifting arm to be in flexible connection with the corresponding main lifting arm is arranged between the corresponding auxiliary lifting arm and the corresponding rotating box. The auxiliarylifting arm comprises a sliding section which is in sliding fit with the main lifting arm and a rotating section which is in running fit with the sliding section. The rotating sections of the two auxiliary lifting arms are connected with each other to form an enclosed hoisting beam. According to the invention, deck space is effectively saved, loading capacity is large, operation is flexible, andworking radius is effectively increased.

Description

technical field [0001] The invention relates to the technical field of marine exploration hoisting equipment, in particular to a special combined hydraulic lifting hoist for scientific research ships. Background technique [0002] At present, with the needs of people's life and the increasing development of production, hoisting equipment is more and more widely used around us. It can use mechanical devices to hoist and transport larger and heavier objects as needed, avoiding manual labor. Handling materials manually reduces the labor intensity of workers and improves the efficiency and quality of material handling. It has greatly improved work efficiency and promoted the rapid development of various industries such as machinery, construction, automobiles, and ships. For example, CN201268559Y discloses a folding crane, which is convenient for disassembly and assembly, flexible and convenient to use, and occupies a small area. CN103434941A discloses a folding crane, which is...

Problems solved by technology

[0005] The two types of cranes disclosed above, one is a foldable type and the other is a straight arm type, both of which have advantages and disadvantages. Although the foldable type cranes save space and are flexible in operation, their loading capacity is relatively small. Although the loading capacity of the machine is large, it is bulky overall, inconvenient to operate, low in operating efficiency, and takes up a large space
