Dismounting wharf crane

Abstract

The invention provides a dismounting wharf crane, which comprises a base plate, a base, a rotary body and a suspension arm, wherein the base comprises a middle sleeve, a first support component, a second support component and a bearing; the bearing is arranged in the middle sleeve; the first support component and the second support component are fixedly connected to the middle sleeve; the rotary body comprises a rotary shaft and a rotary arm which is fixedly connected with the rotary shaft; the rotary arm can rotate with the rotation of the rotary shaft; the rotary shaft is inserted into the bearing of the middle sleeve of the base; the first end of the suspension arm is connected with the rotary body, and the second end of the suspension arm is provided with a chain block; the suspension arm rotates with the rotation of the rotary body; and a tensioning piece is arranged between the rotary body and the suspension arm and is tensioned and fixed by the chain block. By the technical scheme, the dismounting wharf crane has enough strength and a few machine parts, is corrosion-resisting, small in volume and light in weight, and can realize quick assembly and disassembly without auxiliary equipment.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a detachable wharf crane. Background technique [0002] Coastal wharf cranes are greatly affected by the corrosive marine climate environment, and the wharf cranes must be designed for anti-corrosion. If the cranes are fixedly installed on the wharf, they are affected by the corrosive climate of the sea all the year round, and the corrosion problem is even more serious. If the crane can be quickly disassembled and moved to the warehouse for storage when it is not in use, and can be quickly installed when it is used, its service life will be greatly extended. [0003] However, in the harsh environment of the "three highs" at the seaside, there are many constraints on the installation of disassembled dock cranes: high requirements for material anti-corrosion performance, each individual component must meet the weight limit of manual handling, and there is no auxiliary installati...

Problems solved by technology

However, the above requirements are contradictory in the implementation of design and manufacture. For example, the rigidity of corrosion-resistant steel is generally low, and it is quite difficult to take into account various design requirements.
