Description

[Detailed explanation of the invention] This invention mainly consists of two Z
This invention relates to a control handle for operating a type propulsion device.

Conventionally, the two Z-type propulsion devices installed on the tugboat were operated using the main engine speed control lever and forward/backward control lever provided on each of the two Z-type propulsion devices.
This is done by operating a total of five levers and handles, including a rotating handle that controls the two Z-type propulsion devices at the same time, but it has the drawback of requiring a very high level of skill. For this reason, a total of three levers are used: one lever that controls the ship's direction and speed depending on the tilting direction and tilting angle, and the main engine speed lever installed on each of the two Z-type propulsion devices. Although something has been developed, there are also complaints about poor operability.

This invention has a simple structure, good operability, and can be operated easily with both hands, and it is also possible to accurately control two Z-type propulsion devices without requiring very advanced technology. The purpose is to provide a steering wheel.

In order to achieve the above object, the present invention includes a rotary shaft that is rotatably provided in the circumferential direction, an intermediate shaft that is attached to the free end of the rotary shaft so as to protrude in the radial direction of the rotary shaft, and a handle body that traverses a plane that includes the shaft and the intermediate shaft and is attached to the free end of the intermediate shaft such that both ends thereof, which are disposed on the left and right sides of the rotating shaft, are rotatable within a plane parallel to the plane; A grip part is attached to each end of the handle body so as to be rotatable in the circumferential direction, and a grip part is attached to the rotating shaft to detect rotation of the rotating shaft in the circumferential direction and output the detection signal to the central processing unit of the ship. a left/right detection device that turns the two Z-type propulsion devices installed in the same direction and at the same angle to change the direction of the ship from left to right, and a rotating shaft and an intermediate shaft that are attached to the handle body. The rotation of the handle body, which rotates both ends in a plane parallel to the above plane, is detected and the detection signal is output to the central processing unit.
a fore-and-aft detection device that changes the ship's traveling direction forward and backward by turning the shaped propulsion devices in different directions and at the same angle;
Two speed controllers that are individually attached to the grip portions and individually detect rotation of the grip portions in the circumferential direction and use the detection signals to individually control the rotational speeds of the propellers of the two Z-type propulsion devices. The configuration includes a detection device.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

This rotating shaft 1 is provided in a cockpit (not shown) so as to be freely rotatable in the circumferential direction. An intermediate shaft 2 is attached to the free end of this rotating shaft 1.
protrudes in the radial direction of the rotary shaft 1 and is also attached so as to be freely rotatable in the circumferential direction, and a handle body 3 is attached to the free end of the intermediate shaft 2. The handle body 3 includes the rotating shaft 1 and the intermediate shaft 2.
It is provided so as to be rotatable in the circumferential direction, with both left and right end portions disposed on the left and right sides of the rotating shaft 1, and with both the left and right end portions facing a plane F1 parallel to the plane _F1 . , it can be rotated with _F2 . Further, grip portions 5 and 6 are attached to both left and right ends of the handle body 3 so as to be rotatable in the circumferential direction, respectively. Note that half bodies 4 are attached to both ends of the handle body 3, making the handle body 3 substantially annular.

A left and right detection device 7 such as a potentiometer is attached to the rotating shaft 1. The left and right detection device 7 detects rotation of the rotating shaft 1 in the circumferential direction, and is connected to the central processing unit 8 . The intermediate shaft 2 has a lateral movement detection device 9 such as a potentiometer that detects rotation of the intermediate shaft 2 in the circumferential direction, and the handle body 3 has a potentiometer that detects rotation of the handle body 3 with respect to the intermediate shaft 2. Front and rear detection devices 10 such as meters are respectively attached, and are connected to the central processing unit 8 similarly to the left and right detection devices 7.

Here, the central processing unit 8 receives the detection signal outputted from the left and right detection device 7 and issues a command to the turning control devices 11 and 12 to control the two Z-type propulsion devices 13 and 14 provided on the ship S. The two vessels rotate in the same direction and at the same angle to change the traveling direction of the ship S to the left or right, and upon receiving the detection signal output from the lateral motion detection device 9, send a command to the rotation control devices 11 and 12. The Z-type propulsion devices 13 and 14 are turned to predetermined positions to move the ship S laterally, and furthermore, in response to the detection signal output from the fore-and-aft detection device 10, the turning control device 11, 1
2 and the Z-type propulsion devices 13, 1 of the above two aircraft.
4 are turned in different directions at the same angle to change the traveling direction of the ship S back and forth.

The grip portions 5 and 6 are provided with speed detection devices 15 and 1 that individually detect rotation of the grip portions 5 and 6 in the circumferential direction.
6 are attached to the grips 5 and 6, respectively, to detect the amount of rotation of the grips 5 and 6 and send the detection signal to speed control devices 17 and 18.
It is now output to . Z type propulsion device 1
3 and 14 are well-known devices, and are rotatably attached to the ship S, and the worm 2 is rotated by a rotary drive device 19.
A propeller 25 is provided on a casing 22 which is rotated via a transmission mechanism 24 such as a bevel gear by a propulsion drive device 23.

The swing control devices 11 and 12 are connected to the swing drive devices 19 of the Z-type propulsion devices 13 and 14, and
The speed control devices 17, 18 are Z-type propulsion devices 13, 1
The swing control devices 11 and 12 operate the swing drive device 19 according to command signals output from the central processing unit 8, and the speed control devices 17 and 18 The rotation speed of the propulsion drive device 23 is controlled in accordance with command signals output from the speed detection devices 15 and 16. In addition, Z-type propulsion device 1
A follow-up transmitter (not shown) is attached to each of the turning control devices 11 and 14 to control the turning of the Z-type propulsion devices 13 and 14 based on commands from the turning control devices 11 and 12, respectively.
It is designed to feed back to 12. When detection signals are output from the detection devices 7 and 10 at the same time, the central processing unit 8 adds and subtracts (simple combination) the detection signals and outputs the rotation control device 11,
12, and when a detection signal is issued from the lateral movement detection device 9, the two Z-type propulsion devices 13 and 14 move at the angle required for the lateral movement of the ship S (this angle is determined by the ship). For example, when moving to the left,
From the neutral state, turn the left Z-type propulsion device 13 about 60 degrees clockwise, and the right Z-type propulsion device 14 about 45 degrees clockwise.
rotation control devices 11, 1 so as to rotate individually
Issue a command to 2. Note that if the detection signal of the lateral movement detection device 9 is outputted overlapping with the output signals of the other detection devices 7 and 10, the signals of the detection devices 7 and 10 are ignored and the detection signal of the lateral movement detection device 9 is output. It is also possible to give priority to the signal, or to ignore the signal from the lateral movement detection device 9 except in the neutral state.

Next, the operation of the operating handle of the present invention constructed as described above will be explained with reference to some representative examples from FIGS. 5 to 23.

FIG. 5 shows a neutral state; in this state, no commands are issued from each detection device 7, 9, 10, 15, 16, and therefore the two Z-type propulsion devices 13, 14 are lined up horizontally, and ship S is stopped at that spot. Figure 7 shows the case where the handle body 3 is fully tilted forward; in this case,
The front and rear detection device 10 detects the rotation of the handle body 3 with respect to the intermediate shaft 2, and outputs it to the central processing unit 8.
The central processing unit 8 sends command signals to the swing control device 11,
12 to activate the swing drive device 19, move the propellers 25 of the two Z-type propulsion devices 13 and 14 to the rear of the ship S as shown in FIG.
Make 3 and 14 parallel. In this case, the movement of the Z-type propulsion devices 13 and 14 from FIG. 5c is 90 degrees counterclockwise for the Z-type propulsion device 13, and clockwise for the Z-type propulsion device 14.
It is 90 degrees. Therefore, ship S is propeller 2 at that time.
Move forward by receiving 100% of the thrust of 5. Handle body 3
When the angle of inclination is reduced to 1/2, the Z-shaped propulsion devices 13 and 14 form a V-shape as shown in FIG. 6c to move the ship forward. At this time, COS θ of the thrust of the thruster 25
It only works to move the ship forward. Handle body 3
rearward (front side) as shown in Figures 8 and 15.
When the handle body 3 is raised, the Z-shaped propulsion devices 13 and 14 turn in different directions at the same angle,
Propeller 25 on the front side (upper side in Figures 8 and 15)
to move ship S backwards. In this case, the Z-type propulsion device 13 rotates clockwise from the neutral state, and the other Z-type propulsion devices 14 rotate at the same angle counterclockwise from the neutral state.

As shown in Fig. 13, rotate the handle body 3 counterclockwise 90 degrees and tilt it forward, or
As shown in Figure 4, when the handle body 3 is rotated 90 degrees clockwise and raised rearward, the Z-shaped propulsion device 13,
14 turns as shown in Fig. 13c to turn the ship counterclockwise on the spot. In the case of the former shown in Fig. 13, by the operation shown in Fig. 13, Z is changed from the neutral state shown in Fig. 5.
The Z-type propulsion devices 13 and 14 both turn 90 degrees clockwise, and the Z-type propulsion device 13 rotates counterclockwise from the state of a above by the output from the front and rear detection device 10 by the operation shown in FIG. The Z-type propulsion devices 14 each rotate 90 degrees clockwise to the state shown in FIG.
In the latter case shown in Figure 14, perform the operation in Figure 14 to
Both the Z-type propulsion devices 13 and 14 turn 90 degrees counterclockwise from the neutral state shown in the figure, and the Z-type propulsion device 13 rotates from the state shown in a above by the output from the longitudinal detection device 10 by the operation shown in FIG. The Z-type propulsion device 14 is rotated 90 degrees clockwise and the other Z-type propulsion device 14 is rotated 90 degrees counterclockwise to the state shown in FIG. 13c. Even if the two operations a and b are performed at the same time, or even if the order of the operations a and b is changed, the same result will be obtained.

When the handle body 3 is fully tilted forward as shown in Fig. 10 and rotated slightly clockwise, the
The Z-type propulsion devices 13 and 14 become obliquely parallel to each other and change the direction of movement of the ship S to the right.
As shown in the figure, when the forward tilt angle of the handle body 3 is reduced to 1/2, only the left Z-type propulsion device 13 turns rearward, as shown in figure c, and the other Z-shaped propulsion devices facing laterally In cooperation with the propulsion device 14, the ship S is turned to the right. As can be seen from the above description, when the left and right detection devices 7 and the front and rear detection devices 10 output simultaneously, the central processing unit 8 simply adds and subtracts these output signals to the turning control devices 11 and 10.
Issue a command to 2. In this case, the movements of the two Z-type propulsion devices 13 and 14 are a combination of the movements when signals are output independently from the left and right detection devices 7 and the front and rear detection devices 10.

Furthermore, when the handle body 3 is rotated clockwise around the intermediate shaft 2 as shown in FIG. The Z-type propulsion devices 14 each rotate approximately 45 degrees to move the ship laterally to the left.

In all operations, when the grip part 5.6 is rotated in the circumferential direction, the rotation angle is detected by the speed detection device 1.
5 and 16 detect and send detection signals to the speed control devices 17 and 18 to change the rotational speed of the propulsion drive device 23.

In the above embodiment, the intermediate shaft 2 is attached to the rotating shaft 1 so as to be rotatable in the circumferential direction, but the intermediate shaft 2 is fixed to the rotating shaft 1 and the handle body 3 is rotated in the circumferential direction of the intermediate shaft 2. You can also do it as you like.

In addition, by only rotating the rotating shaft 1 in the circumferential direction and rotating the handle body 3 up and down using the free end of the intermediate shaft 2 as a fulcrum, it is possible to create two machines as shown in Figures 22c and 23c. Since it is also possible to move the ship S laterally by moving the Z-type propulsion devices 13 and 14, the rotation of the handle body 3 about the intermediate shaft 2 and the detection device 9 for lateral movement
can be omitted.

As explained above, the steering handle of the present invention includes a rotating shaft that is rotatable in the circumferential direction, an intermediate shaft that is attached to the free end of this rotating shaft so as to protrude in the radial direction of the rotating shaft, and a handle body that traverses a plane that includes the shaft and the intermediate shaft and is attached to the free end of the intermediate shaft such that both ends thereof, which are disposed on the left and right sides of the rotating shaft, are rotatable within a plane parallel to the plane; A grip portion rotatably attached to each end of the handle body in the circumferential direction;
The two Z-type propulsion devices attached to the above rotating shaft detect rotation in the circumferential direction of the rotating shaft and output the detection signal to the central processing unit, causing the two Z-type propulsion devices installed on the ship to turn in the same direction and at the same angle. a left/right detection device that changes the traveling direction of the handle body to the left or right, and a left/right detection device that is attached to the handle body and detects the rotation of the handle body that rotates both ends within a plane parallel to the plane that includes the rotation axis and the intermediate axis. A forward and backward detection device that outputs the detection signal to the central processing unit and turns the two Z-type propulsion devices in different directions and at the same angle to change the direction of the ship forward and backward; A configuration comprising two speed detection devices that individually detect circumferential rotation of the grip portion and individually control the rotational speeds of the propellers of the two Z-type propulsion devices based on the detection signals. Therefore, by grasping the two grips individually with both hands, you can rotate the handle body around its rotation axis, tilt it back and forth using the free end of the intermediate shaft as a fulcrum, and use the grip as well. By rotating the handle of the unit, the rotation and speed of the two Z-type propulsion devices can be controlled. The movements of the two hands during the above operation are all the same except for turning the two left and right grips individually, with one hand performing the left and right rotation operation and the other hand performing the up and down movement. Since there are no differences between the two, it is possible to maneuver the ship relatively easily, accurately, and with plenty of margin, without requiring advanced skills.
