JPH0755011B2 - Automatic open / close kite catcher - Google Patents

Description

Description: TECHNICAL FIELD The present invention relates to a kite removing device for removing a kite entangled in an electric wire, which is used for straddling a drum wheel provided in the device on the electric wire. The opening and closing are automatically performed.

[Prior Art and Problems] A box body having a rectangular cross section is vertically divided into two parts, one side of which is hingedly connected, and an auxiliary spring is used to constantly close the box body. -1528 is known. An operation rod 7 is connected to the upper box, and a rope 10 is connected to the lower box. That is, the operating rod is grasped by one hand, and the rope is pulled by the other hand to open the box body so that the electric wire can be inserted and removed. The operating rod is a component, apart from the wires in the lower position,
It cannot be applied to the electric wire at a high position that is beyond the control rod.

[Means for Solving Problems] In order to be able to use the electric wire in a high place, the kite catcher of the present invention is composed of an outer frame and an inner frame. Both can be raised and lowered freely at a predetermined interval, and the drum wheel is provided in the inner frame. When a worker on the steel tower suspends the outer frame, the inner frame is lowered by gravity and an opening is opened between both frames. When the electric wire is inserted and the drum is laid over it, and the suspension of the outer frame is released, the outer frame descends by gravity and the opening is automatically closed. When a worker on the ground tows the rope hanging from the outer frame, the kite can be cut and removed by the cutting blade provided on the inner and outer frames.

[Examples] The drawings will be described by taking an example in which two drums are provided.

The outer frame 1 has an inverted U-shaped cross section, a lifting hook 2 is provided on the base side, and two long holes 1a and 1b are vertically formed on both leg sides. The inner frame 3 has both long and short leg sides 3a and 3b on both sides of the top side, and a horizontal lower side 3c is provided at the lower end of the long leg side 3b. The center shaft 4 is rotatably and horizontally supported by both leg sides 3a, 3b of the inner frame, and both ends thereof are inserted into the elongated holes 1a, 1b of the outer frame so as to be vertically movable along the elongated holes. The central shaft 4 pivotally supports a drum 5 at the center thereof. The pair of projecting shafts 6a, 6b are located above the central axis and are located on both sides 3a,
It is planted outward in 3b and engages with the long holes 1a, 1b. The pull-arm arm 7 having a hook-shaped cross-section has a pin 8 at one end, which is pivotally attached to a part of the outer frame on the long leg side 3a side, and the other end locks a pull handle 9 below the lower side 3c of the inner frame. Cutting blades 10 and 11 are fixed to the end faces of the inner and outer frames, respectively, and project forward and backward in the traveling direction of the kite catcher.

The present invention is configured as described above. An operator on a steel tower hooks the tip of a work rod (not shown) on a hoisting hook to hang the kite catcher and opens it as shown in FIG. The electric wire E is inserted into this, and the drum 5 is laid over the electric wire. When the work bar is removed from the lifting hook, the outer frame descends due to gravity, closing the opening as shown in FIG. The ground worker has the lower end of the rope R and tows along the electric wire. Since the outer frame and the inner frame are constrained by both the central axis and the projecting axis, the relative attitude of the two is not broken by towing, and the kites and kites are cut by the cutting blades 10 and 11. After that, the kite catcher pulls to the nearest steel tower, hangs the lifting hook again to remove the kite and the kite string, and removes the kite catcher from the electric wire.

[Effect] It can be used regardless of whether the electric wire is high or low.

Claims (1)

[Claims] 1. An outer frame having an inverted U-shaped cross section having a lifting hook on a base side and vertical elongated holes formed on both leg sides, and a top side, both long and short leg sides, and a horizontal lower side connected to the long leg sides. An inner frame that is vertically inserted into the frame, a central shaft that is horizontally supported by both legs of the inner frame and both ends are vertically inserted into the outer frame long hole, and a center shaft that supports the drum wheel at the center. A projecting shaft that is planted outwardly on both legs of the inner frame above the shaft and engages with the elongated hole of the outer frame so that it can move up and down. It is composed of a pull arm with a pull handle, and the cutting blade is appropriately projected on the end faces of the inner and outer frames in the transfer direction, and the space between the inner and outer frames is opened by the lifting of the lifting hook, and it is a straddle for the electric wire of the drum. An automatic open / close kite catcher characterized in that the frames are closed by releasing the suspension.
