Description

Heavy duty worm gear swinging liftable all-direction propeller

Technical field:

The utility model relates to a kind of propelling unit, particularly a kind of heavily loaded worm gear swinging liftable all-direction propeller.

Background technology:

At present, the propelling unit that is using is because power is less; In order to increase propelling thrust, need a plurality of miniwatt propelling units of configuration, taken a large amount of spaces; Have influence on other configuration of devices; Cause and on ocean engineering boats and ships such as ocean freight boats and ships, lifting boats and ships, portable oil drilling platform, to use, and along with the increase of various ocean engineering boats and ships water holding capacity, existing L type propelling unit can't satisfy the demand of propelling.

Summary of the invention:

The purpose of the utility model is in order to overcome above deficiency; A kind of later-model heavily loaded worm gear swinging liftable all-direction propeller is provided; Increase angle of rake power greatly, satisfied the demand of modern marine ships that transport, lifting boats and ships, portable oil drilling platform ocean engineering boats and ships.

The purpose of the utility model realizes through following technical scheme: a kind of heavily loaded turbine swinging propelling unit, comprise a plurality of elevating rams, electrical motor and drop-gear box, and the electrical motor outside is provided with a plurality of elevating rams; Be connected with coupler in the electrical motor lower end; Be connected with castellated shaft in the coupler lower end, the coupler lower end is connected with hollow shaft through castellated shaft, is connected with lifting tube in the elevating ram lower end; And hollow shaft is located in the lifting tube; Be provided with drop-gear box in the lifting tube lower end, in a side of drop-gear box high-performance screw propeller be installed, it is secondary to be provided with a plurality of turbine and worms in the outside of hollow shaft upper end; And the secondary lower end of turbine and worm is connected with drop-gear box, and elevating ram quantity is 2-5.

The utility model compared with prior art has the following advantages:

Have compact conformation, use and characteristics easy for installation, increased the angle of rake power of heavily loaded turbine swinging, satisfied the job requirements of ocean engineering boats and ships such as ocean freight boats and ships, lifting boats and ships, portable oil drilling platform.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Label among the figure: 1-elevating ram, 2-electrical motor, 3-drop-gear box, 4-coupler, 5-castellated shaft, 6-hollow shaft, 7-lifting tube, 8-screw propeller, 9-turbine and worm pair.

The specific embodiment:

In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is done further to detail below, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.

Show a kind of embodiment of a kind of heavily loaded worm gear swinging liftable all-direction propeller of the utility model like Fig. 1, comprise a plurality of elevating ram 1, electrical motor 2 and drop-gear box 3, electrical motor 1 is fixed on the basis of cabin; Electrical motor 2 electrical motors 2 outsides are provided with a plurality of elevating rams 1, are connected with coupler 4 in electrical motor 2 lower ends, are connected with castellated shaft 5 in coupler 4 lower ends; Coupler 4 lower ends are connected with hollow shaft 6 through castellated shaft 5; Be connected with lifting tube 7 in elevating ram 1 lower end, and hollow shaft 6 is located in the lifting tube 7, is provided with drop-gear box 3 in lifting tube 7 lower ends; Side at drop-gear box 3 is equipped with screw propeller 8; Be provided with a plurality of turbine and worms in the outside of hollow shaft 6 upper ends secondary 9, and the lower end of turbine and worm secondary 9 is connected with drop-gear box 3, and elevating ram quantity is that 2-5 is individual.

During use; Electrical motor 1 drives castellated shaft 5 through coupler 4; Castellated shaft 5 drives drop-gear box 3 through hollow shaft 6 and moves up and down, and drop-gear box 3 drives screw propeller 8 and rotates, and transmission of power is arrived screw propeller 8; Elevating ram 1 is lifted into hull interior with the screw propeller 8 on lifting tube 7, drop-gear box 3 and the drop-gear box 3, thereby has realized the boat certainly of dynamic positioning and boats and ships; Turning force drives drop-gear box 3 through turbine and worm secondary 9, and drop-gear box 3 drives screw propeller 8, and screw propeller 8 give boats and ships with omnibearing thrust, thereby boats and ships has been realized the ability of omnidirectional maneuver around 360 ° of revolutions.
