Prevent stalls in directions A2 and B2. When each of the pipelines 13 and 34 is connected to the pump port, each of the ports 12a of the hydraulic motors 11 and 32,
33a becomes the pump pressure, and the take-up reels 30 and 31 can be rotationally driven in the take-up directions A1 and B1, respectively.

Next, the operation of the emergency stop device 1 will be described. First of all, at the time of lifting net, each winch for fishing 5,
After winding the rope 6 around the winding drums 10 and 31 of No. 7, the net 4 is wound up. First, when the winches 5 and 7 are not driven, the switching valves 15 and 36 are in the neutral positions P3 and Q3, and the pipelines 19, 37 and 38 are driven by the hydraulic pump 16 driven by the power of the main engine 8.
The hydraulic oil is supplied to the tank 17, and the hydraulic oil collected in the tank 17 is again pumped up from the pipe 18 by the hydraulic pump 16 and circulated. In this condition, the winch for fishing 5
When the operator operates the operating lever 52 of the switching valve 15 to switch the spool 51 to the first position P1 in order to wind the rope 6 around the take-up drum 10, the hydraulic oil in the pipeline 19 is transferred to the pipeline 13. , Which causes one port 12a of the hydraulic motor 11 to have a higher pressure than the other port 12b,
The winding drum 10 is rotationally driven in the winding direction A1. In this state, each of the pipelines 19 and 13 is connected to the pump port and constitutes a supply pipeline. Another winch for fishing 7
Since the switching valve 36 of is in the neutral position Q3,
37 and 38 are connected to the tank port and form a return line.

When the rope 6 and the net 4 are wound up by the one winch 5 in this way, the operator 43 operates the operating lever 52 of the switching valve 15 to switch the spool 51 to the neutral position P3. Similarly, the other winch 7 also operates the operating lever 54 of the switching valve 36 to operate the spool 5
3 is switched to the first position Q1. This allows the conduit 19,
37 and 34 communicate with each other and are connected to the pump port to form a supply line. As a result, one port 33a of the hydraulic motor 32 becomes higher in pressure than the other port 33b,
The winding drum 31 is rotationally driven in the winding direction B1, and the net is wound. At this time, the pipelines 35 and 38 are connected to the tank port to form a return pipeline.

When the rope 6 or the net 4 is entangled during the work of winding the rope 6 and the net 4 around the winding drums 10 and 31 in such a lifting net,
The operator 43 operates the transmitter T to generate a stop signal, and the receiver R receiving the stop signal outputs the lines to the lines L1 and L2. In response to this output, the stopping means 40 shuts off the conduit 38 which is a return conduit connected to the tank port,
The hydraulic motors 11 and 32 are stopped and the clutch 23 is disengaged to cut off the power from the main engine 8 to the hydraulic pump 16. The stopping operation of the stopping means 40 will be described in more detail. The electromagnetic solenoid of the electromagnetic on-off valve 41 is excited by the output of the receiver R, and the pilot conduit 4
Cut off 4. As a result, the pressure in the pilot line 44 increases, and the line 38 is blocked until the pressure in the pilot line 44 reaches the set pressure of the relief valve 42.
Therefore, when winding the rope, the winding drum 10 is braked to prevent rotation due to inertia in the winding direction A1, and when winding the net, the winding drum 31 is braked to wind the winding direction B1.
Rotation due to inertia is prevented. In this way, the operator 43 can quickly stop the winches 5 and 7 by the transmitter T during the fishing net.

When the rope 6 and the net 4 are wound around the take-up drum 10 at the time of throwing the net, the operator first of all, in order to throw the rope 6, one winch 5 is used.
The operation lever 52 of the side switching valve 15 is operated to switch the spool 51 to the second position P2. At this time, the other winch 7 remains stopped, and therefore the switching valve 36
The spool 53 is arranged at the neutral position Q3. In this state, the conduits 19 and 14 are connected to the pump port, so that the other port 12b of the hydraulic motor 11 has a higher pressure than the one port 12a, and the winding drum 10 is rotationally driven in the rewinding direction A2. It At this time, the pipelines 19 and 14 constitute a supply pipeline, and the pipelines 13, 37 and 38 constitute a return pipeline.

When the rope 6 wound on the winding drum 10 is thrown in this way, the operator 43 operates the operation lever 52 of the switching valve 15 to move the spool 51 to the second position P.
2 to the neutral position P3, and the operating lever 54 of the other switching valve 36 is operated to move the spool 53 to the neutral position Q3.
To the second position Q2. This allows the conduit 19,
37 and 35 are connected to the pump port, and the hydraulic motor 32
The other port 33b becomes higher in pressure than the one port 33a, so that the winding drum 31 can be rotationally driven in the rewinding direction B2 to cast the net. At this time, the pipeline 19,
A supply line is constituted by 37 and 35, and the line 3
A return line is constituted by 4, 38.

Also during such a net throwing operation, when the rope 6 or the net 4 is entangled with the winding drums 10 and 31, it becomes an emergency, and the operator 43 operates the transmitter T to give a stop signal. When the winch 5 or 7 is transmitted, the pipeline 38 serving as a return pipeline is shut off by the stopping means 40, the clutch 23 is shut off, and the rewinding direction A2 of each winding drum 10, 31 is set. B
Rotation due to inertia to 2 can be blocked and stopped quickly.

As described above, since the operator 43 can carry the transmitter and quickly stop the winches 5 and 7 in an emergency, the ropes and nets wound by these winches 5 and 7 can be stopped. The damage can be eliminated or reduced as much as possible, and the safety can be improved.

In order to unlock the state where the winches 5 and 7 are stopped in an emergency, an unlocking switch is provided in the receiver R or the transmitter T, and the stopping means 40 and the clutch 23 are provided.
May be released at the same time, or the stopping means 4 may be operated by first operating the release switch.
After releasing only the disengaged state of 0, the disengaged state of the clutch 23 may be released by the following operation.

[0025]

As described above, according to the present invention, the emergency stop signal transmitted from the portable transmitter in an emergency is received by the receiver, and the fishing winch is stopped in response to the output of the receiver. As a result, the time from the occurrence of an emergency to the stop of the winch can be significantly shortened compared to the case where the stop switch is installed at a remote position as in the past. It is possible to reduce damage to fishing gears that are caught or rewound, and improve safety.

Further, according to the present invention, the fishing winch is driven by the hydraulic oil supplied through the supply line, and the stop means is provided in the return line of the hydraulic oil. A plurality of hydraulic motors can be stopped simultaneously or individually by the stop means. Moreover, since the return pipe is closed by the stopping means, rotation of the winch due to inertia can be prevented, and the time for the winch to completely stop can be significantly shortened.

Further, according to the present invention, since the clutch is interposed between the power source and the hydraulic pump, not only the rotation of the hydraulic pump can be quickly blocked in an emergency, but also the power to the hydraulic pump can be prevented. Can also be unlocked, which improves safety.
