2, and a steering wheel 35 composed of arm portions 33A, 33B, 34A, 34B which are projected to the left and right at 180-degree symmetrical positions of the boss portion 32 and are arranged in pairs one above the other at predetermined intervals.
On both sides of this rudder handle 35, each arm 33A, 33B, 34
A pair of left and right hydraulic cylinders 3 corresponding to A and 34B
6, 37, a rudder angle transmitter 38 that reads the rotational movement amount of the boss portion 32, and a hydraulic unit (not shown) that operates the hydraulic cylinders 36, 37, and further includes the pair of hydraulic cylinders 36, Cylinder bodies 39 and 40 of 37 are supported swingably in the horizontal plane on the hull side via support pins 41, respectively, and the tip ends of piston rods 42 and 43 of hydraulic cylinders 36 and 37 correspond to them, respectively. The upper and lower arm portions 33A, 33B, 34A, 34B are rotatably connected via a connecting pin 44. In this case, the mounting angle of both hydraulic cylinders 36, 37 to the rudder handle 35 at the neutral position of the rudder is

問題があった。Problems to be solved by the invention Recently, it has been desired to improve the steering performance of a ship, and the conventional steering angle range was 35 degrees to the left or right, or sometimes 40 degrees, but a larger rudder angle, for example, left and right. It is required to reach 70 degrees or more. by the way,
According to the conventional steering device, each piston rod 42, 43
The top end of each of the upper and lower arm parts 33A, 33B, 34A, 3
Since it is attached to the rudder handle 35 at a position between 4B, the piston rods 42 and 43 come into contact with the boss portion 32 of the rudder handle 35 when trying to take a large rudder angle. Therefore, in order to avoid this, the distance from the center of the rudder axle 31 to the center of each connecting pin 44,
That is, it is necessary to unnecessarily increase the rudder operating radius, and accompanying this, it is necessary to increase the piston stroke of the hydraulic cylinder required to obtain a predetermined steering angle, and to make the hydraulic cylinder long. Therefore, there is a problem that the entire length and width of the steering device become large, making it difficult to dispose the steering device on the narrow floor surface of the ship and also increasing the manufacturing cost.
そこで、本考案は、かかる従来の油圧シリンダー方式

結したものである。Means for Solving the Problem In order to solve the above problems, a steering device for a ship according to the present invention steers the boss portion of a steering wheel which includes a boss portion and an arm portion projecting from a side portion of the boss portion. Externally fixed to the shaft top,
A supporting boss portion whose upper surface is located above the rudder shaft and the upper end surface of the boss portion is provided at the tip of the arm portion to support the hydraulic cylinder on the deck so that the hydraulic cylinder can swing in a horizontal plane, and the piston of the hydraulic cylinder A connecting boss is provided at the tip of the rod, the connecting pin is vertically inserted over both the connecting boss and the support boss, and the connecting boss and the connecting pin are rotatable through a spherical bearing.

によって舵角の操作精度が損なわれることはない。Action In the above configuration, the connecting pin that connects the rudder and the piston rod of the hydraulic cylinder that operates the rudder is projected upward at the support boss portion whose upper surface is located above the rudder shaft and the upper end surface of the boss portion. Therefore, unlike the conventional case, the piston rod of the hydraulic cylinder does not contact the boss portion of the steering wheel and the rudder shaft, so that the steering angle can be increased without unnecessarily increasing the steering wheel operating radius. Also, the connecting structure of the connecting boss portion and the supporting boss portion is such that the connecting pin has one side inserted into the connecting boss portion and the other side inserted into the supporting boss portion, and there is almost no exposed portion of the connecting pin, and bending strength is high. Even if the point of action of the hydraulic cylinder and the point of action of the steering wheel that receives the force of the hydraulic cylinder are separated in the vertical direction, the accuracy of the steering angle is impaired due to bending and damage of the connecting pin. It will not be done.

て舵角の操作精度が損なわれることはない。In the neutral position of the rudder shown in FIG. 1, when a command is issued to take the right rudder, for example, pressure oil is supplied to the oil port 18 of the first hydraulic cylinder 4 and the oil port 19 of the second hydraulic cylinder 5. , The piston rod 15 of the first hydraulic cylinder 4 projects from the cylinder body 11, and the piston rod 16 of the second hydraulic cylinder 5 is the cylinder body 12
It retreats inside and rotates the rudder handle 3 to the right rudder side as shown by the phantom line in FIG. 1 (indicated by arrow A). At this time, the rotational position of the steering wheel 3 is input to a control device (not shown) that controls the hydraulic unit via the steering angle transmitter 6, and when the commanded right steering angle matches, a stop signal is output. Then, the supply of pressure oil to the hydraulic cylinders 4 and 5 is stopped, and the rudder is held at that position. Next, when a command for left rudder is issued, pressure oil is supplied to the oil port 20 of the first hydraulic cylinder 4 and the oil port 21 of the second hydraulic cylinder 5, respectively, and the piston rod 15 of the first hydraulic cylinder 4 becomes While retreating into the cylinder body 11, the piston rod 16 of the second hydraulic cylinder 5 projects from the cylinder body 12 and causes the rudder 3 to cooperate and rotate to the left rudder side (indicated by arrow B). Then, as in the case of the right rudder command, when the commanded rudder angle is reached, the pressure oil supply is stopped by the signal from the rudder angle transmitter 6, and the rudder is held at that position. In all of these operations, the connecting pin 10 that connects the rudder handle 3 and the hydraulic cylinders 4 and 5 is provided so as to project upward from the upper end surface of the rudder shaft 1, so that the piston rod
There are no obstacles in the 15 and 16 range of motion, so
Any steering angle can be taken in the entire range in which the pushing force or the pulling force of the piston rods 15 and 16 can give the steering wheel 3 a rotational force. Further, since there is almost no exposed portion of the connecting pin 10 and the bending strength is large, even if the point of action of the force of the piston rods 15 and 16 and the point of action of the force on the arm portions 8 and 9 are separated in the vertical direction, they are connected. The operation accuracy of the rudder angle will not be impaired by bending or damage of the pin 10.

損なわれることはない。Effect of the Invention According to the configuration of the present invention described above, since the connecting pin that connects the rudder handle and the piston rod of the hydraulic cylinder that operates this is projected above the upper end surface of the rudder shaft, even if both hydraulic cylinders are parallel. However, the piston rod of the hydraulic cylinder does not come into contact with the rudder shaft as well as the boss of the rudder as in the conventional case, so it is not necessary to unnecessarily increase the rudder operating radius. Also increase the steering angle, for example
It can be set to 70 degrees or more, so that the installation area of the steering device does not have to be wide and the manufacturing cost is not high. Also, since the connecting pin has almost no exposed portion and has a large bending strength, even if the point of action of the force of the hydraulic cylinder and the point of action of the force on the steering wheel that receives the force of the hydraulic cylinder are separated in the vertical direction, The steering accuracy of the rudder angle is not impaired by bending or damage.
