The present invention relates to a radio-controlled hook metal fitting for hanging a rope with a ring that can be released automatically.

  The loaded rope has a ring at both ends, the rope is hung on the wood, the rope is submerged in one ring, and the other ring is hooked on the hook of the cable transporter. As a result, the wood is connected to the transporter. The transporter is connected to a wire rope stretched between a pulley connected to a standing tree and a winch attached to a boom of a heavy machine such as an excavator, and is therefore moved by operation of the wire rope by the winch. By such movement of the transporter, the wood is pulled up or down to the gathering point according to the topography of the forest. In either case, when the wood reaches the gathering point, remove the rope from the hook of the transporter, then remove the rope from the wood, hook the removed rope onto the hook of the transporter, and remove the transporter from its original position. Return to position. Although it is easy to hang the ropes on the hooks, hanging the ropes on the timber is a difficult task, and depending on the topography of the forest, it is a dangerous task.

  An object of the present invention is to loop or load a rope with a ring such as a wire rope or a fiber rope on wood, hook the loop of the looped or loaded rope, and require hooking manually. The object is to provide a radio-controlled hook fitting for loading a rope with a ring that can be automatically released by a radio-controlled operation.

  A further object of the present invention is to provide a radio-controlled hook fitting for hooking a rope with a ring, in which the hook is automatically rotated so that the ring of the rope is detached from the hook when the hook is released. There is to do.

  The above object of the present invention is to provide a main body having a lateral hole for passing a rope with a ring, an outward position where a ring of the rope with a ring can be hung and removed, and an inward position for hanging the ring. A U-shaped hook that is urged by a spring so as to rotate in an outward direction, and the U-shaped hook is rotated from an outward position to an inward position against the action of the spring. When triggered, a trigger that can be pushed down from the standby position to the free position by the U-shaped hook, and the trigger is connected to the lateral pin so that it can be pulled down from the unlocked position to the locked position in conjunction with the push-down operation of the trigger. The lock pin that engages and locks the U-shaped hook when the U-shaped hook tries to return by the action of a spring in the locked position, and a lever that can be rotated outward and inward An operating device that is actuated by a radio wave receiver and that rotates the lever in an outward direction, and the lever is located around the lock pin by rotating the lever in the outward direction, A rope loading radio control, wherein a lock pin is lifted from a lock position to a lock release position via a coil spring interposed between the pin and the U-shaped hook is rotated outward by the action of a spring. This is accomplished by providing a type hook fitting.

  According to the present invention, the main body includes an upper case connected to each other, a lower case, and a holder provided in the upper case, and a horizontal hole is provided in an upper part of the upper case and is biased by a spring. The hook is pivotally attached to the lower case, the trigger has a horizontal bar, and the push-down operation of the trigger is performed by the U-shaped hook engaging with the horizontal bar by the rotation of the U-shaped hook. The operating device has two lever arms and acts on one lever arm to rotate the lever outward, thereby compressing the coil spring interposed between the other lever arm and the lateral pin. .

  According to the present invention, the operating device is fixed to the rotating shaft of the geared motor and is rotated by the rotation of the motor to rotate the lever in the outward direction, so that it acts on the protruding surface of one lever arm of the lever. It should consist of a crank with rollers.

  According to the present invention, the radio receiver further includes an antenna embedded in a groove formed in the outer periphery of the upper case of the main body and protected from being exposed to the outside by a plastic ring, and receives radio waves via the antenna. Thus, an electrical signal for switching on to activate the geared motor is generated.

  According to a preferred embodiment of the present invention, a limit switch attached to a holder of the main body is provided, and the limit switch moves upward in conjunction with the operation of the lock pin and the trigger in order to stop the rotation of the geared motor.

  The U-shaped hook is in a rotational position in the outward direction by the action of a torsion spring. Pass a wire rope through the side hole of the upper case of the main body, turn the rope around the wood, and hang the rope ring on the U-shaped hook. The U-shaped hook is turned inward by a finger against the spring action of the torsion spring. The trigger is pulled down from the standby position to the free position by turning the U-shaped hook. The lock pin is pushed down to the lock position in conjunction with this movement of the trigger, and when the holding force by the finger is released from the U-shaped hook, the U-shaped hook tries to return somewhat by the action of the torsion spring, so that it hits the lock pin. Thus, the U-shaped hook is locked with the lock pin. This completes the loading with the rope. By pulling the rope, the wood is roped and carried by pulling a wire rope connected to such rope.

  Regarding the release of the lock pin, when the radio wave is emitted by operating the remote controller, the radio wave receiver receives the radio wave via the antenna, emits an electrical signal for switching on, and activates the geared motor. When the geared motor is activated, the roller-equipped crank pushes the protruding surface to rotate the lever outward, thereby pulling the lock pin through the coil spring and the U-shaped hook from the locked position to the unlocked position. At the same time, the trigger is similarly lifted from the free position with respect to the U-shaped hook to the standby position. As the lock pin moves to the unlocking position, the U-shaped hook is rotated outward by the spring action of the torsion spring. When the U-shaped hook is turned downward, the rope ring naturally comes off from the U-shaped hook.

The lower case 5 is provided with a longitudinal slot 8 that passes downward on the longitudinal center line, and the case portions 9 and 9 on both sides thereof are wire ropes to be hung on a metal U-shaped hook 11 described below. Or the substantially C-shaped recessed part 10 and 10 wound inward for guiding the ring | wheel of a fiber rope to the outer side of a case part is formed. In the case portions 9 and 9, in the case of fiber ropes, protrusions 10 'and 10' adapted to receive the rope rings are provided on the outer surface of the case parts 9 and 9 in order to prevent the rope rings from moving backward. It is also possible (see FIG. 12).

  The U-shaped hook 11 is located in the vertical groove hole 8 of the lower case 5, crosses the vertical groove hole 8, and is pivotally connected to pivot pins 12 having both ends fixed to the case portions 9, 9. . As best seen in FIG. 8, the torsion spring 13 includes two coil portions 14b connected by a central portion 14a, the central portion being hung on a U-shaped hook, the coil portion being disposed around the pivot pin 12, Both end portions 15 and 15 are hooked to the shelf portions 16 and 16 of the case portions 9 and 9, whereby the torsion spring 13 rotates the U-shaped hook 11 in the outward direction around the pivot pin 12. The spring load is received, that is, the pressure is accumulated. The U-shaped hook 11 has two arms, that is, an outer arm that is pushed by a finger to rotate the U-shaped hook 11 in the inward direction against the spring force of the torsion spring around the pivot pin 12. 17 and an inner arm 21 having an abutment surface 20 adapted to engage with a lateral bar 19 of a trigger 18 described later when the U-shaped hook is turned inward.

  The horizontal bar 19 of the trigger 18 is constructed by folding the lower part of the trigger so that it can receive a part of the inner arm 21 of the U-shaped hook 11, as best seen in FIGS. Then, guide holes 22 and 23 provided in alignment with each other in the holder 6 and the lower case 5 are guided so as to be movable up and down between the standby position and the free position. The lock pin 24 is arranged in parallel with the trigger 1 in the longitudinal direction, and is provided in the holder 6 and the lower case 5 in alignment with the upper portion 26 passed through the upper guide hole 25 provided in the holder 6. And a lower portion 29 passed through the guide hole 27 and the guide hole 28, and the lock pin 24 is guided by the guide holes 25, 27, 28 so as to be movable up and down between the locked position and the unlocked position. Is done. A horizontal pin 30 penetrates the lock pin 24 in the horizontal direction, is fixed thereto, passes through a longitudinal hole 6 ′ provided in the holder 6, extends toward the trigger 18, and penetrates the upper end of the trigger 18. It is fixedly connected there. Thus, the trigger 18 and the lock pin 24 are connected to each other via the lateral pin 30 so that the operation is interlocked. The trigger, lock pin, and horizontal pin are all made of metal.

  As described above, the trigger 18 is pivoted in the inward direction of the U-shaped hook 11, and the inner arm 21 hits the horizontal bar 9 and pushes it down to be pushed down from the standby position to the free position. The lock pin 24 is pushed down to the lock position in conjunction with this operation of the trigger 18.

  A metal lever 31 has two lever arms 33a and 33b which are perpendicular to each other, and is pivotally attached to the holder 6 by a pivot pin 32 so as to be able to turn inward and outward. The shorter horizontal lever arm 33a of the lever 31 has an annular shape for receiving the lock pin 24. The spring receiver 34 is disposed between the lever arm 32 and the lateral pin 30 around the lock pin 24. A coil spring 35 is interposed between the two. This spring is in a state of being somewhat subjected to a spring load, that is, in a state of being somewhat compressed, for reasons that will be described later. The longer vertical lever arm 33b of the lever 31 has a protruding surface 36 above it and a protrusion 37 at its upper end.

  As shown in FIGS. 9 and 10, the geared motor (motor with a speed reducer) 38 is held by the holder 6 and comes into contact with the projecting surface 36 of the lever arm 33 b of the lever 31 on the rotating shaft 39. A metal roller crank 41 is fixedly attached. In this example, the geared motor and the crank with a roller constitute an operating device. When the rotary shaft 39 is rotated by the start of the geared motor 38, the roller crank 41 pushes the protruding surface 36 to rotate the lever 31 outward about the pivot pin 32, thereby the lock pin via the coil spring 35. 24 is pulled up from the lock position for locking the U-shaped hook to the lock release position for releasing the hook (see FIG. 4). At the same time, the trigger 18 is similarly lifted from the free position with respect to the U-shaped hook to the standby position. The coil spring 35 is further compressed between the lever arm 33a and the lateral pin 30 by the rotation of the lever 31. The unlocking position of the lock pin 24 at the time of unlocking is regulated by the lateral pin 30 hitting the top surface of the long hole 6 'of the holder 6 (see FIGS. 4 and 6).

  The geared motor 38 is activated by a wireless device. The wireless device includes a remote controller (not shown) and a radio wave receiver 46 (FIGS. 5 and 7) electrically connected to an antenna 43 that receives radio waves emitted from the controller and held by a hogder. . The antenna 43 is embedded in a groove 44 formed on the outer peripheral surface of the lower case 6 and is protected from being exposed to the outside by a plastic ring 45 fitted on the outer peripheral surface of the lower case 5 (see FIGS. 4 and 6). ). The radio wave receiver 46 receives radio waves via the antenna 43 and thereby generates an electrical signal for switching on to activate the geared motor 38. As is clear from FIGS. 9 and 10, a battery 49, which is a power source for the geared motor 38, is housed in the holder 47. When the crank turns a predetermined angle, it is necessary to stop the rotation of the geared motor. This is done by a limit switch 48 as shown in FIGS. The limit switch 48 is attached to the holder 6 adjacent to the head 30 ′ of the lateral pin 30 and is operated by the head 30 ′ of the lateral pin 30 that moves upward in conjunction with the operation of the lock pin and the trigger 18. The operation piece 59 is provided. Thus, the limit switch is switched off by the operation of the operating piece. At this time, the lever 31 is rotated toward the original position by the action of the compressed coil spring 35, that is, returned to the motor. Therefore, the crank is freely pushed back to the original position by the rotation of the lever 31.

  The upper case 4 is provided with a manual unlocking device 60 for manually unlocking the lock pin 24 when the battery runs out. The manual unlocking device 60 is inserted into a horizontal hole 61 provided in the upper part of the upper case 4, and a tip is provided around the push rod 62 and a push rod 62 facing the protrusion 37 of the lever arm 33 b of the lever 31. Return coil spring 63. Thus, when the lock pin 24 is in the lock position for locking the hook, the lever 31 can be rotated by pushing the push rod 62. As a result, the lock pin 24 is brought into the unlock position by the method described above. Can be raised.

  The usage of the hook metal fitting according to the present invention will be described below. 4 and 5 show the unlocked state, and the U-shaped hook 11 is in the outward rotation position indicated by the solid line by the action of the torsion spring. The wire rope 1 is passed through the horizontal hole 7 of the upper case 4 of the main body, the rope is turned around the wood, and the rope ring is hung on the U-shaped hook 11. Next, the U-shaped hook 11 is rotated by the finger in the inward direction against the spring action of the torsion spring 13. At that time, in the case of the fiber rope, the loop of the rope hung on the hook is received by the protrusions 10 ′ and 10 ′ of the lower case as well understood from FIG. 12. As the U-shaped hook 11 rotates, its inner arm 21 engages with the horizontal bar 19 at the standby position of the trigger 18 to pull the trigger 18 down to the free position. The lock pin 24 is pushed down to the locked position in conjunction with this movement of the trigger 18, and when the holding force by the finger is released from the U-shaped hook, the U-shaped hook tries to return somewhat by the action of the torsion spring. The U-shaped hook hits the pin and is locked by the lock pin. This completes the loading with the rope. By pulling the rope, the wood is roped and carried by towing a wire rope connected to a rope with a ring.

  Next, how to release the lock pin 24 will be described. When the remote controller is operated to emit radio waves, the radio receiver 46 receives radio waves via the antenna 43, emits an electrical signal for switching on, and activates the geared motor 38. When the rotary shaft 39 is rotated by the start of the geared motor 38, the roller crank 41 pushes the protruding surface 36 to rotate the lever 31 outward about the pivot pin 32, thereby the lock pin via the coil spring 35. 24 is pulled up from the locked position where the U-shaped hook 11 is locked to the unlocked position for releasing the hook. At the same time, the trigger 18 is similarly lifted from the free position with respect to the U-shaped hook to the standby position. By the movement of the lock pin 24 to the unlock position, the U-shaped hook 11 is rotated outward about the pivot pin pivot pin 12 by the spring action of the torsion spring 13. At that time, the ring of the wire rope is rebounded by the bending thereof, and in the case of the fiber rope, it is received by the protrusion, so that the U-shaped hook is naturally removed from the U-shaped hook by being directed downward.
