Abstract
The invention discloses a propulsion unit of a self-propelling crane ship, which comprises a box body internally provided with a frequency converter, a transformer, a propelling motor and a controller. The propelling motor is connected with the frequency converter through lines, the frequency converter is connected with the transformer through lines and the transformer is connected with the controller. The invention has the advantages of simple structure and improved work efficiency.
Description
Technical field
The present invention relates to a kind of propelling unit of self-propulsion type crane ship.
Background technology
Crane ship generally is divided into two classes, a kind of be crane arm can 360 degree rotating, another kind is the fixing direction aboard ship of arm, whole ship turns to by the tugboat traction, or lean on ship to cast anchor to all directions, anchor chain by the tractive different directions, it is rotating to implement weight, and crane ship is divided into non-from boat and self-propulsion type again, and the frequent crane ship of operation generally all adopts self-propulsion type, and the general propulsion system that adopts traditional diesel main engine as crane ship of this self-propulsion type crane ship, the operation of crane ship generally all is to carry out in the river, when therefore adopting diesel main engine work, not only can pollute the working environment of crane ship, and reduce the work efficiency of crane ship.
Summary of the invention
The objective of the invention is provides a kind of simple in structure in order to overcome above deficiency, the propelling unit of the self-propulsion type crane ship of increasing work efficiency.
Purpose of the present invention is achieved through the following technical solutions: a kind of propelling unit of self-propulsion type crane ship, described propelling unit comprises casing, in casing, be provided with frequency converter, voltage transformer, propulsion electric machine and controller, propulsion electric machine is connected with frequency converter by circuit, frequency converter is connected with voltage transformer by circuit, and voltage transformer is connected with controller.
The present invention compared with prior art has the following advantages: substitute the propelling unit of the crane ship of original diesel main engine and unpowered systems by adopting electric propulsion apparatus, guarantee that so not only crane ship in use reduces the pollution to working environment, and improved the work efficiency of crane ship.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Number in the figure: 1-casing, 2-frequency converter, 3-voltage transformer, 4-propulsion electric machine, 5-controller.
The specific embodiment:
In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
Show a kind of embodiment of the propelling unit of self-propulsion type crane ship of the present invention as Fig. 1, described propelling unit comprises casing 1, in casing 1, be provided with frequency converter 2, voltage transformer 3, propulsion electric machine 4 and controller 5, propulsion electric machine 4 is connected with frequency converter 2 by circuit, frequency converter 2 is connected with voltage transformer 3 by circuit, voltage transformer 3 is connected with controller 5, controller 5 also can be directly installed on the outside face of casing, by adopting by adopting electric propulsion apparatus to substitute the propelling unit of the crane ship of original diesel main engine and unpowered systems, guarantee that so not only crane ship in use reduces the pollution to working environment, and improved the work efficiency of crane ship.
