Abstract
The invention provides a liftable and lowerable marine auxiliary steering device, and the components are as following: a motor (2) is arranged in a boat body (1), and an output shaft (2a) is arranged on the motor (2). The liftable and lowerable marine auxiliary steering device is characterized in that a transmission shaft (4) is connected onto the output shaft (2a) through a universal joint (3); a coupler (4a) is arranged on one end of the transmission shaft (4); a hydraulic cylinder (5) is arranged, and two ends of a tubular piston rod (6) of the hydraulic cylinder (5) penetrate through a piston (5); a gear box (7) is connected to the upper end of the piston rod (6); the lower end of the piston rod (6) penetrates through the boat body (1) so as to be connected with a propeller (8). The liftable and lowerable marine auxiliary steering device is simple in structure and convenient to be operated, and the propeller can be driven to stretch up and down through the action of the hydraulic cylinder, and the boating resistance generated when the steering device does not work can be effectively reduced, and the probability that the auxiliary steering device is wound by underwater impurities is reduced.
Description
Technical field:
The present invention relates to propeller for watercraft propelling unit, is exactly a kind of liftable ship auxiliary steering devices of boats and ships specifically.
Background technology:
Ship turning device general at present all adopts stern to turn to the mode of rudder, and manual or hydraulic operation, the position of its rudder is relatively fixing, only can do the rotation action of certain angle.In use, the tune of boats and ships is turned to often need to adjust in advance repeatedly or the process that falls back to carry out.So the steering reaction of boats and ships is comparatively slow, often there is ship when the visbility such as dense fog, heavy rain is lower and dodge too late accident of freeing.Although also provide a kind of ship auxiliary steering device in prior art, because most assistant steering device is positioned at hull bottom all the time, resistance when ship runs can be increased, too increase by the probability of foreign material winding under water simultaneously.
Summary of the invention:
The present invention is exactly to overcome deficiency of the prior art, provides a kind of structure simple, easy to operate, liftable ship auxiliary steering device.
The invention provides following technical scheme:
A kind of liftable ship auxiliary steering device, it is included in hull and is provided with motor, and motor is provided with output shaft, it is characterized in that: on output shaft, be connected with transmission shaft by universal-joint, is provided with coupler in one end of transmission shaft; In hull, arrange hydraulic actuating cylinder, the two ends of the tubular piston bar of described hydraulic actuating cylinder are through piston; Be connected with gear case in the upper end of piston rod, the lower end of piston rod connects a propelling unit after running through hull; In described piston rod, be provided with propelling unit transmission shaft, the upper end of propelling unit transmission shaft is stretched in gear case, and end is provided with bevel gear is formed with the gear in gear case and coordinate; The lower end of propelling unit transmission shaft is stretched in propelling unit, and the bevel gear that its end is provided with engages with propelling unit middle gear and forms power transmission and coordinate; The input shaft of gear case forms transmission by coupler and motor and coordinates.
On the basis of technique scheme, following further technical scheme can also be had:
Be provided with one in the bottom of described hull and form with described propelling unit the depression coordinated.
The invention has the advantages that:
Structure of the present invention is simple, easy to operate, propelling unit can be driven to stretch up and down by the effect of hydraulic actuating cylinder, can reduce the navigate resistance of steering hardware when not working by actv., reduces the probability that assistant steering device is wound around by foreign material under water.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is schematic diagram when the present invention works in Fig. 1.
Detailed description of the invention:
As shown in Figure 1, 2, a kind of liftable ship auxiliary steering device, it is included in hull 1 and is provided with motor 2, universal-joint 3 is provided with in one end of the output shaft 2a of motor 2, make output shaft 2a form power transmission with transmission shaft 4 by universal-joint 3 and adapter shaft 3a to coordinate, be provided with coupler 4a in one end of transmission shaft 4.
Arrange hydraulic actuating cylinder 5 in the bottom of hull 1, described hydraulic actuating cylinder 5 is the two rod hydraulic ram of single piston type, thus piston 5a be arranged on the middle part of piston rod 6.Hydraulic actuating cylinder 5 is also provided with oil inlet 5b and oil outlet 5c.
Be connected with gear case 7 in the upper end of piston rod 6, the other end of piston rod 6 runs through a hull 1 rear connection propelling unit 8.
Described piston rod 6 is tubulose, is provided with propelling unit transmission shaft 8a wherein, and the lower end of propelling unit transmission shaft 8a is stretched in propelling unit 8, and the bevel gear that its end is provided with engages with propelling unit 8 middle gear and forms power transmission and coordinate.
The upper end of propelling unit transmission shaft 8a extends upwardly in gear case 7, and the bevel gear 8b that end is provided with is formed with the input shaft gear 7a in gear case 7 and coordinates.
Described input shaft gear 7a is arranged on the input shaft 7b of gear case 7, forms transmission coordinate after the casing of gear case 7 is stretched out in one end of input shaft 7b by coupler 4a with motor 2.
The hull that piston rod 6 runs through around hull 1 is provided with a depression 1a, and described depression 1a volume is greater than the volume of propelling unit 8 so that propelling unit 8 can cave in wherein.
The direction that in this programme, propelling unit 8 advances and hull 1 length direction form an angle.
Principle of work:
As shown in Figure 1, when hydraulic oil flows out from oil outlet 5c, when flowing into from oil inlet 5b, under the effect of hydraulic oil, in-oil cylinder piston 5a rises, and drives propelling unit 8 to rise interior filling in hull bottom depression 1a.
As shown in Figure 2, when hydraulic oil flows out from oil inlet 5b, when flowing into from oil outlet 5c, under the effect of hydraulic oil, in-oil cylinder piston 5a declines, drive propelling unit 8 decline from hull bottom depression 1a stretch out.Open motor 2 to start working to propelling unit 8 transmitting power propelling unit simultaneously, play the function that auxiliary ship turns to.
