Description

The present invention relates to a wire winder.

Conventionally, during power transmission line construction, the length of electric wires strung between power transmission towers is adjusted (tensioned) so that the slack falls within the range specified in the design. In this work, a metal wire called a tension wire is used, and a wire pulling means such as a tension winch is used to pull and pay out the wire. The pulled wire is ejected from the wire pulling means and spread out on the ground.

If the work continued in this state, there was a risk that the worker would get tripped by the wires and fall, so it was necessary to wipe off the dirt from the wires spread out on the ground and tie them up, which was time-consuming. Therefore, there is a need for a wire winder that easily accommodates the wire pulled by the wire pulling means.

Patent Document 1 discloses a wire storage device that includes a container that accommodates wires, a swinging pipe that is swingably suspended above the container, and a guide pipe that guides the wire to the swinging pipe. Disclosed. In this wire storage device, the wire discharged from the winch device passes through the swinging pipe from the guide pipe and is discharged from the lower end of the swinging pipe. When the wire is pressed against the inner surface of the container, the force generated by the bending or deformation of the wire causes the swinging conduit to swing. The movement direction of the wire is regulated by the swinging of the swinging conduit, and the wire is housed in the container.

As shown in FIGS. 3 and 4, the container 2 has a cylindrical side wall 2b that extends upward from the peripheral edge of the bottom portion 2a, which is circular in plan view. The extending portion 2c extends. The inner peripheral side of the extending portion 2c is an opening 21 that is circular in plan view.

Further, a circular opening is formed in the bottom portion 2a of the container 2 at approximately the center, and a rotating shaft 22 extending upward from the bottom portion 2a is formed on the inner peripheral side of the opening. The rotating shaft 22 is located approximately at the center of the opening 21 and extends approximately vertically from the bottom portion 2a to approximately the same height as the extension portion 2c. The container 2 is rotatable around a rotating shaft 22.

The rotating shaft 22 has a cylindrical shape that opens downward, and a support shaft 30 is connected to the lower part of the rotating shaft 22 inside the opening. The support shaft 30 is inserted through the opening of the bottom portion 2a and connected to the inner peripheral side of the rotating shaft 22 via the bearing 23, so that the frame body 3 rotatably supports the container 2. Note that when the wire is unwound from the container 2, the container 2 rotates in a direction opposite to the direction of rotation when the wire is wound due to the force of pulling the wire.

A support shaft 30 that supports the rotating shaft 22 is fixed to the frame 3. The frame 3 includes a pedestal 31 to which a support shaft 30 is fixed, a pair of columns 32, 32 extending upward from the pedestal 31, a rail member 33 installed on the pair of columns 32, 32, and a rail. It has a mounting member 34 fixed to the member 33.

The pedestal 31 is assembled from, for example, a hollow square piece, and is formed to be slightly larger than the outer periphery of the container 2 when viewed from above, thereby ensuring stability and allowing the container 2 to be installed on the ground. The frame body 3 is connected to the container 2 at a support shaft 30 provided at the center of the pedestal 31, and does not contact the container 2 at other parts.

It can be easily fixed to the rail member 33. The mounting member 34 has a plate-shaped height adjustment piece 35 extending upward from the end above the opening 21, and has an L-shape when viewed from the side.

FIG. 5 is a front view of a wire winder according to an embodiment of the present invention. As shown in FIG. 5, the height adjustment piece 35 has a first adjustment slit 35a that extends upward and opens along its length. The introduction pipe 4 is fixed to the mounting member 34 by being screwed to the height adjustment piece 35 so that the height can be adjusted along the first adjustment slit 35a. In FIG. 5, the introduction tube 4 shown by the two-dot chain line is obtained by changing the angle and height of the introduction tube 4 shown by the solid line with respect to the rotation axis 22.

The introduction pipe 4 guides the wire discharged from the discharge port 101 of the wire pulling means 100 to the container 2. As shown in FIG. 3, the introduction tube 4 is a tubular member through which the wire accommodated in the container 2 can be inserted, and includes at least three members: a straight section 40, a first curved section 41, and a second curved section 42. The slits 40a, 41a, and 42a, which are wider than the diameter of the wire, are formed to open over the entire length, so that the wire can be easily inserted into the introduction tube 4. Note that the width of the slits 40a, 41a, and 42a is not limited, but is preferably 15 mm to 20 mm for a wire with a diameter of 10 mm, for example.

The straight portion 40 is formed from a circular tube extending linearly, and is provided with a slit 40a over the entire length thereof. The straight portion 40 has a plate-shaped fixing piece 43 extending along its length, and is attached to the frame 3 at the fixing piece 43 .

A second adjustment slit 43a that opens along the length direction is formed in the fixed piece 43. A screw 44 is inserted into a position where the second adjustment slit 43a of the fixed piece 43 and the first adjustment slit 35a of the height adjustment piece 35 are overlapped, and depending on the position of the screw in the first adjustment slit 35a and the second adjustment slit 43a, , the introduction tube 4 is positioned in the height direction and the length direction of the straight portion 40. Further, the angle of the straight portion 40 is variable using the screw 44 as a fulcrum.

The position where the screw 44 is fixed becomes the fixing part 44 where the introduction tube 4 is fixed to the height adjustment piece 35. Therefore, the introduction tube 4 has a fixed part 44 along the length direction of the straight part 40. The introduction tube 4 is fixed to the mounting member 34 via a height adjustment piece 35 so that the position of the introduction tube 4 can be adjusted at the fixed portion 44 . Furthermore, the introduction tube 4 is configured to be rotatable about the fixed portion 44 as a fulcrum, so that its angle with respect to the rotation axis 22 is variable. The range of the adjustable angle is not limited, but is from 0 degrees to 90 degrees, more preferably from 30 degrees to 60 degrees, with respect to the rotation axis 22.

The first curved portion 41 extends from one end of the straight portion 40 toward the inside of the container 2 . The first curved portion 41 is formed from a curved circular tube, and is provided with a slit 41a along its entire length. Moreover, since the first curved part 41 has an outer diameter smaller than the inner diameter of the straight part 40, it is inserted into the inner periphery of the straight part 40, and the introduction tube 4 can be expanded and contracted by advancing and retreating in the length direction of the straight part 40. It is. Further, the first curved part 41 is rotatable about the straight part 40, and is screwed after determining the angle of the end from which the wire is discharged.

The second curved portion 42 extends from the other end of the straight portion 40 toward the outside of the container. The second curved portion 42 is formed from a curved circular tube, and is provided with a slit 42a along its entire length. Moreover, since the second curved part 42 has an outer diameter smaller than the inner diameter of the straight part 40, it is inserted into the inner periphery of the straight part 40 and expands and contracts the introduction tube 4 by moving it forward and backward in the length direction of the straight part 40. It is possible. Further, the second curved portion 42 is rotatable about the straight portion 40, and is screwed after determining the angle of the end portion connected to the discharge port 101 of the wire pulling means 100.

Further, the second curved portion 42 has a tapered portion 45 at an end connected to the outlet 101 of the wire pulling means 100, which widens as it moves away from the introduction pipe. The introduction pipe 4 is connected to the discharge port 101 by placing the tapered portion 45 over the discharge port 101 of the wire pulling means 100 and tightening the screw.

As explained above, according to the wire winder 1 according to this embodiment, when the wire is guided into the container 2 from the opening 21 by the introduction tube 4 and comes into contact with the side wall 2b, the wire is The force pushed out by the wire pulling means 100 becomes a torque that rotates the rotating shaft 22, and the container 2 rotates. As the container 2 rotates, the wire is wound up while being accumulated from the outer circumferential side to the inner circumferential side inside the container 2, and can be easily accommodated inside the container 2. Since the force by which the wire is pushed out from the wire pulling means 100 is utilized, there is no need for the wire winder 1 itself to be equipped with power, and the wire winder 1 can be constructed so compactly that it can be easily carried.

Further, the introduction pipe 4 can be positioned in the radial direction of the container 2 by the rail member 33, and can be adjusted at an angle with respect to the rotation axis 22 of the container 2 by screwing in the first adjustment slit 35a and the second adjustment slit 43a. The first curved section 41 and the second curved section 42 are configured to be movable forward and backward relative to the straight section 40 to extend and contract. It becomes possible to rotate the first curved part 41 and the second curved part 42 around the straight part 40. As a result, when connecting the second curved portion 42 of the introduction tube 4 to the outlet 101 of the wire pulling means 100, the connection can be easily made by adjusting the angle, length and position of the introduction tube 4. By adjusting the length of the wire and the angle of the first curved part 41, even if it becomes difficult to rotate the container 2 with a certain amount of wire accommodated, the position where the wire is guided can be finely adjusted so that the wire can be easily rotated.

The embodiments described above are merely illustrative in all respects and should not be interpreted in a limiting manner. Furthermore, all modifications and changes that come within the scope of equivalents of the claims are intended to be within the scope of the present invention.

For example, in this embodiment, the height adjustment piece 35 is provided with a first adjustment slit 35a that is open in the length direction, but the height of the introduction tube 4 can be adjusted along the height adjustment piece 35. It is not limited to slits as long as it is adjustable. Similarly, the fixing piece 43 is provided with a second adjustment slit 43a that opens along the length direction, but has a fixing part 44 of the introduction tube 4 along the length direction of the straight part 40, It is not limited to a slit as long as the introduction tube 4 can be rotated about the fixed part 44 as a fulcrum.

Further, in the present embodiment, the first curved part 41 and the second curved part 42 have a smaller diameter than the straight part 40, and are configured to be inserted into the inner circumference of the straight part 40 so that they can move forward and backward. The first curved part 41 and the second curved part 42 have an inner diameter larger than the outer diameter of the straight part 40, and the straight part 40 is inserted into the inner periphery of the first curved part 41 and the second curved part 42 to advance and retreat. It may be possible.
