Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention relates to a device for preventing a rope from slipping off a railroad car, and more specifically, Attached to the shore of a fishing boat used for the operation of fresh aquaculture, remove a large number of nets containing scallops. A large number of ropes attached to the hull are suspended at a specified interval, I fixed it on the port side so that it would not come off from the railroad car. It is related to the disconnection prevention device.

[0002]

[Prior art]

  The fishing boats used to operate the scallop aquaculture are as shown in Fig. 1. 00, from the bow side to the stern side, the sheave 101, the intermediate roller 102, and the sheave 1 03 is attached. And during operation, many nets 10 containing scallops A number of ropes 105 to which 4 are attached are hung at predetermined intervals, They are mounted on these carts 101 and 103. In addition, these wheel 101, 103 is a cylinder having an annular flange on the inside and a ratchet-like flange on the outside. The body is rotatably attached to the shaft. Also, the nail wheel has a net attached It is for passing a string.

[0003]

[Problems to be solved by the device]

  However, the rope rope 106 as described above is simply mounted on the rope wheels 101 and 103. Because it is only worn, when the wind blows or the hull sways due to moss, Also, when the hull moves, it often comes off the vehicle and interferes with operation. won.

[0004]   In addition, in order to solve this point, for example, a guide with a hook-shaped or U-shaped cross section is used. It can be used, but many ropes 105 are hung on the rope 106. Therefore, the string 105 is an obstacle and cannot be passed through. Also, support by hand If it gets wrong, the work efficiency will be impaired.

[0005]   The present invention has been made in view of the above points, and the rope is supported during operation. To prevent it from coming off the car, pass a string of ropes suspended from the rope without obstacles. It can now be stored in the hull when not needed. It is intended to provide a device for preventing the vehicle from hanging off from the push car.

[0006]

[Means for Solving the Problems]

  Thus, the gist of the present invention is that the base is on the upper surface of the port in the ship. Attach a mounting ring to the tip of a supporting arm that is pivotally attached to the outside, and attach the required ring to the mounting ring. A support shaft of a length is inserted, and the support shaft has a circle of the required length at the upper end. Insert it through the center of the rotation guide tube with an annular flange and rotatably support it. Therefore, the rope is not guided between the ship's port and the rotation guide tube. It is in the device to prevent the rope from slipping off the rope car.

[0007]   Further, in the above structure, the support shaft is mounted via the set bolt provided on the mounting ring. The position of the rotation guide tube in the height direction can be adjusted by appropriately shifting the position of You may be able to do so.

[0008]

[Embodiment of device]

  Embodiments of the present invention will be described below.   Fig. 1 is an explanatory view of the fishing boat when the present invention is in operation, and Fig. 2 is the present invention when it is not needed. FIG. 3 is a perspective view of a device according to the present invention, and FIG. 3 is a partially longitudinal side view of the device according to the present invention.

[0009]   The fishing boat, the cart and the intermediate rollers are as described above. And again, scallop A number of ropes with a large number of nets attached are hung at specified intervals, and a rope is attached. It is also as described above to ride on the cart.

[0010]   Thus, the hook-and-stick prevention device 1 according to the present invention is mounted near the bow side of a railroad car. The base is turnable inboard and outboard on the upper surface of the port 100 in the hull. A mounting ring 3 is fixed to the tip of a support arm 2 pivotally attached to the mounting arm 3, and the mounting ring 3 is supported for a required length. The shaft 4 is inserted, and the supporting shaft 4 is formed into an annular shape having a required length at the upper end. Insert it in the center of the rotation guide tube 6 provided with the flange 5 and rotatably support it. , The rope rope 106 is guided between the ship's port 100 and the rotation guide tube 6 and allowed to pass therethrough. It came to be done.

[0011]   Further, a set bolt 7 is attached to the attachment ring 3 fixed to the tip of the support arm 2. And appropriately shift the position of the support shaft 4 through the set bolt 7. The position of the rotation guide cylinder 6 in the height direction can be adjusted by . Reference numerals 2a and 2b denote support members for supporting the support arm 2 on the upper surface of the port 100 of the hull.

[0012]   Further, an annular handle 8 is attached to the upper end of the support shaft 4 and A nut 9 as a stopper is screwed into the threaded portion (not shown) at the lower end. .

[0013]   Further, a ratchet-like flange 6a is provided at the lower end of the rotation guide tube 6. .

[0014]   Next, the operation of this embodiment will be described.   During operation, turn the support arm 2 and position the rotation guide tube 6 outside the ship's side 100. Let As a result, the rope rope 106 that has been laid on the rope cart 101 is shown in FIG. As described above, the hull side 100, the rotation guide tube 6 and the flange 5 on the upper end side are formed. It comes to move through the space. And this makes the rope 106 It is possible to prevent the pick-up wheel 101 from coming off. Also, low When the cap 106 moves, the string 105 that is hung from now on is the hook-and-loop flange. Although it enters into the respective concave portions of 6a, the rotation of the rotation guide tube 6 causes no trouble in the backward direction. It is something that moves.

[0015]   Further, FIG. 2 shows a state when unnecessary, in which case the support arm 2 is rotated. By doing so, the rotation guide tube 6 is retracted inside the port of the ship. This way Since the rotation guide tube 6 can be retracted inside the hull side of the ship except during work, It does not interfere with the running or work of the ship.

[0016]   Next, a modification of the rotation guide tube 6 shown in FIG. 4 will be described.   In this example, the flange provided at the lower end of the rotation guide tube 6 is an annular flange with a short length. 6b. In this case, when the rope rope 106 moves, The string 105 hung from there is moved to the rear while slidingly contacting the annular flange 6b. It moves.

[0017]

[Effect of device]

  Since the present invention has the structure and operation as described above, the wind blows or the ship is Even if it shakes, the rope can prevent the rope from coming off the truck. is there. It is possible to pass a large number of strings suspended from a rope without obstruction. It is something. Also, when it is not needed other than during operation, turn the support arm to attach the rotation guide tube to the hull. It can be retracted inside the port. Interfere with running and work It does not become.
