Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a safety device for a longline hoisting machine that prevents a decrease in operational efficiency due to tangling of branch lines during hoisting.

Conventional technology In longline fishing, the main line, which can reach a total length of 160 km, must be hoisted at high speed. This often causes the aircraft to get stuck in the aircraft or injure the crew, forcing the hoisting operation to be halted, making it impossible to improve operational efficiency.

In order to deal with this, as seen in Japanese Utility Model Application Publication No. 59-139060, a rope pulling roller of a longline winding machine was developed.
It is known to install a sensing plate on the front of the longline winding machine that the tangled branch lines come into contact with, and to stop the longline hoisting machine via a limit switch when activated. Since the longline winding machine is stopped each time the line is hoisted, safety for workers can be ensured, but the efficiency of hoisting long lines is not much different from that of the conventional method, and there is a drawback that the work efficiency cannot be improved.

Problems to be Solved by the Invention In this invention, the tangled branch ropes that are not likely to get caught on the aircraft or pose a danger to human bodies are lifted as they are, and the tangled branch ropes that protrude toward the aircraft are pulled into the aircraft. Automatically detects only branch ropes that may hang or injure crew members on the sides of the aircraft, preventing operational stoppages and injury to crew members due to tangling of branch ropes, making winding work more efficient. This should be done quickly.

Means for Solving the Problem The present invention has a structure for achieving the above-mentioned object, in which an arcuate anti-entanglement frame is provided in the front part of the rope pulling roller of a longline reeling machine in a substantially horizontal direction, and the anti-entanglement frame is The gist is that a cord switch is provided which is activated by a branch line that comes into contact with the fuselage from approximately the center of the longline to stop the drive of the longline winding machine.

Embodiment To explain an embodiment of the present invention with reference to the drawings, a longline hoisting machine 2 installed behind a guide device 1 provided on the side is a longline hoisting machine 2 installed at the rear of a guide device 1 provided on the side, and a longline hoisting machine 2 installed at the front part provided on one side of the upper part of the fuselage 3. It is composed of a pulling roller 4, a winding roller 5 located slightly above the rear side, and a pressing roller 6 that presses against the winding roller 5. An arc-shaped roll-in prevention frame 7 is attached to the frame 7, and the arc-shaped roll-in prevention frame 7 is formed of an arc-shaped upper guide rod 8, a lower guide rod 9, and a connecting piece 10 connecting these two. Furthermore, a cord switch 11 for stopping the driving of the longline winding machine 2 is provided from approximately the center of the arc-shaped portion of the lower guide rod 9 to the machine body 3 side.

In the drawing, the code switch 11 is shown as two on the top and bottom as a backup, but it may be one, and re-driving the longline winding machine 2 can be done by operating a separately provided drive switch, or by operating the electromagnetic switching valve of the longline winding machine 2. This is done by switching, etc. Note that 12 is a mounting plate for fixing the entrapment prevention frame 7 to the body 3, and 13 is a lead wire for the cord switch 11.

Since the embodiment of the present invention is constructed as described above, when the main line A is hoisted by the longline hoisting machine 2 and the branch line B is entangled with the main line A and pulled up, the entanglement prevention frame 7 The tangled branch line B, which is distributed to the left and right in an arc-shaped part and distributed to the machine body 3 side, contacts the cord switch 11 and operates it to automatically stop the longline winding machine 2. Further, if necessary, even in the case of the tangled branch rope B distributed to the rope pulling roller 4 side, the operator can operate the cord switch 11 to manually stop the longline winding machine 2.

Effects of the invention The present invention provides an arc-shaped trapping prevention frame in a substantially horizontal direction at the front of the rope pulling roller of a longline winding machine, and a branch line that contacts the machine body from the approximate center of the trapping prevention frame. We installed a code switch that activates and stops the drive of the longline winding machine, so the tangled branch line can be distributed to the left and right by the arc-shaped winding prevention frame, and it can be biased toward the machine body and not tangled around the machine. Only when a tangled branch line that poses a danger to the crew is hoisted up, the cord switch is automatically activated to stop the longline hoist and prevent the main line and branch lines from becoming entangled with the aircraft and the crew. It has excellent features and practicality, allowing long lines to be hauled safely, efficiently, and quickly while preventing operations from being stopped due to injury.
