Description

[Detailed Description of the Invention] [Industrial Field of Application] It is known to attach snow-resistant rings (Japanese Utility Model Publication No. 52-42381) to snow-covered power lines in order to prevent damage caused by freezing. The present invention relates to an installed vehicle that automatically installs this ring.

[Conventional technology and problems] In the past, workers attached the wires manually while moving along the wires. In addition to working at high places, which is inherently dangerous, there were problems such as numbness in the hands due to repeated work using manual scissors, so there was a desire to automate the entire work using electric power.

[Solution] A device that stores multiple rings horizontally in a mounting vehicle suspended from electric wires so that one of the ends is always in a fixed position, and a device that pushes up this end ring from below. A device for crimping the wires was installed.

[Example] The drawings will be explained. Case 1 of the rectangular parallelepiped is
An arm 2 fixed to a side plate is provided with a roller 3, and is suspended from an electric wire E. Moreover, one side plate is provided with a hinge (not shown) at the top and can be opened and closed.
A tape-shaped guide plate 4 is fixed horizontally into the case,
Equipped with multiple rings R aligned with the cuts facing upward. The pressing device is a pusher 5, a roller 6, and a spring 7.
Consisting of: The pusher 5 is in contact with the right end of the ring R, and two pins 5a protrude downward at positions that sandwich the guide plate. Correspondingly, a roller 6 is pivotally supported at the left end of the case. The spring 7 engages with the roller 6 as shown in FIG. 4, and both ends are locked with the pin 5a. Since the pin 5a passes through a long hole (not shown) made in the case bottom plate, the spring 7 causes the pusher 5 to press the ring R to the left. A stopper plate 8 is fixed to both sides of the end plate of the case, and a gap g of the width of ring R1 is provided between the stopper plate 8 and the left end plate 9 of the case. The gap g is open at the top and bottom. The left end plate 9 has a window 9a as shown in FIG. 5, so that the passage of the ring R is not obstructed. Therefore, the ring R pushed by the pusher stops in a fixed position and posture while contacting the stopper plate 8.

The frame 10 is fixed downward to the left end of the case, and pivotally supports a threaded rod 12 by brackets 11 provided on the upper and lower sides. The nut 13 is screwed into the threaded rod 12, and arms 13a protrude from both sides.
This engages with the frame 10 and is prevented from rotating. Therefore, the nut is moved up and down by the forward and reverse rotation of the threaded rod. The slider 14 is slidably inserted into the upper part of the threaded rod, and a spring 15 is inserted between it and the nut 13. The upper end of the rectangular lift bar 16 is fixed perpendicularly to the side surface of the slider, and a long hole 16a is bored in the lower part. This elongated hole engages with a pin 13b protruding from the nut 13. That is, the slider 14 can only move up and down following the nut 13, and the expansion and contraction of the spring 15 is limited to the length of the elongated hole 16a. The push-up plate 17 is fixed vertically to the side of the slider 14, and can be moved up and down the gap g by moving the slider up and down. The guide spring 25 has one side fixed to both sides of the top of the frame 10, and presses on both sides the ring which is pushed up by the pressing plate on the other side. The hook device consists of a hook 18 and a ring 20. A pair of opposing hooks 18
Each base is pivotally connected to the push-up plate 17 with a pin 19. The pair of links 20 are pivotally connected at one end to the bent portion of the hook 18 and at the other end to the arm 13a of the nut by pins 21 and 22, respectively. A pulley 23 is fixed to the lower end of the threaded rod, and is connected to a motor M provided on the frame by a belt 24. Motor M can be switched between forward and reverse rotation.

The present invention is configured as described above. First, the side plate is opened, the pusher 5 is moved backward against the spring 7, and the ring R is loaded. The first ring is located in the gap g. Nut 1 is a threaded rod that drives the motor and rotates in the forward direction.
Raise 3. Slider 14 via spring 15
, and finally the push-up plate 17 touches the guide spring 25.
The ring R contacts the electric wire E via the ring R whose attitude is controlled by the ring R. After this, the nut continues to rise while pressing the spring, and rotates the hook 18, which had been open, in the closing direction via the link 20. The hook 18 receives the ring R from the guide spring 25 and connects the cuts in the ring. Hook 18 in FIGS. 2 and 3 shows this change. At this point the motor rotation is reversed.
The threaded rod reverses and the nut descends back to its original fixed height position. As the nut descends, the pin 13b descends along the elongated hole 16a of the lift bar, but after reaching the lower end of the elongated hole, the slider is lowered together with the nut. Therefore, reception of the next ring pushed out from the end plate 9 into the gap g is not obstructed by the push-up plate. When the nut stops descending to the normal position, the top of the push-up plate 17 is at a height that communicates with the guide plate 4. With this, one cycle is completed. A worker riding on a spacecraft near the mounted vehicle moves the mounted vehicle to the right in FIG. 1 and moves to the next mounting position.

The forward/reverse switching of the motor M can be operated visually, but it is easy to automate it using a limit switch as a normal design.

[Effect] Applied to a car equipped with a motor in 1986-62638.
(Utility Model Application No. 58-166219) is known, but the case has a double bottom, the inner bottom holds the electric wire, and the outer bottom holds the ring, and there are problems with ring loading and other problems, making it difficult to implement. I have to. In contrast, the present invention solves the above problem by using a structure in which the ring loaded below the electric wire is pushed up and installed at a predetermined position.
The feature is that it is easy to implement.
