Abstract
The invention relates to an electric crane, comprising a base which is arranged at one side of a boat deck, a rotating cylinder body which is arranged on the base, a lifting rod of which the lower end part is articulated on the rotating cylinder body, a lifting hook and a driving rope mechanism which is used for driving the lifting hook to lift; the electric crane is characterized in that: a motor and a speed reducing transmission mechanism are arranged in a rotating stand column, an the output end of the speed reducing transmission mechanism is used for driving the driving rope mechanism. The electric crane has a good effect in driving and is simple in structure and is easy to maintain.
Description
Technical field
The present invention relates to a kind of electrodynamic type crane.
Background technology
In the prior art, crane is widely used on boats and ships.Existing crane much all adopts hydraulic-driven, and this makes, and the crane volume is big, complex structure, and maintenance, difficult in maintenance.
Summary of the invention
The object of the present invention is to provide a kind of electrodynamic type crane, this device not only drives effective, and simple in structure, is easy to safeguard.
The objective of the invention is to realize like this: a kind of electrodynamic type crane; Comprise the base of being located at boat deck one side, be located at the transmission rope mechanism that rotating cylinder, bottom on the base are hinged on suspension rod, the suspension hook on the rotating cylinder and are used for the transmission hook lifting; It is characterized in that: be provided with motor and reduction gearing mechanism in the said Rotary cloumn, the mouth of said reduction gearing mechanism is used to drive said transmission rope mechanism.
The invention has the beneficial effects as follows and adopt the work of motor-driven crane that not only drive effectively, maneuverability, and simple in structure is convenient to operation and maintenance, has broad application prospects.
Below in conjunction with accompanying drawing and specific embodiment the present invention is done further detailed description.
Description of drawings
Fig. 1 is the external structure scheme drawing of the embodiment of the invention.
Fig. 2 is the inner structure scheme drawing of the rotating cylinder of the embodiment of the invention.
The specific embodiment
