Description

[Detailed description of the invention] [Field of industrial application] This invention is used to pull the distribution line temporarily installed on a through-pole to the insulator provided on the through-pole when carrying out work on overhead distribution lines. Regarding power distribution transfer equipment.

[Conventional technology]

Conventionally, when pulling a distribution line temporarily installed on a through-pole to an insulator installed on the through-post,
It was done by hand and no special equipment was needed.

[The problem that the idea aims to solve]

Conventional overhead power lines were thin, so the work of drawing them to the insulators could be done manually without any problem. However, as the demand for electricity increased, the difficulty of securing new routes for power distribution lines led to the need for thicker overhead power distribution lines. For example, the number of OC150mm ² overhead wires is increasing, and it is thought that this will continue to increase in the future, but as the wires become thicker, it will become difficult even for two people to do the work.
Moreover, problems have arisen, such as increased danger and longer working hours.

Therefore, the present invention was developed with the aim of solving such problems, and the aim is to provide a power distribution line transfer machine that can be easily performed by one person, and can be done safely and in a shortened working time. be.

[Means to solve the problem]

The line transfer machine of the present invention has a frame constituting the line transfer machine, a fixing means for clamping to the seat of the insulator, a means for hoisting the wire such as a rope to hold and pull the overhead wire, and a wire guiding means. The guide means is constructed by a guide means.

〔Example〕

The invention is embodied by the embodiments shown in the drawings. As shown in FIGS. 1, 2, and 3, the frame 1 is a plate made of synthetic resin.
It has a window hole 2 in its center and protrusions 3, 4, and 5 at both ends of the upper end and in the middle, respectively, and a vertically long grip 6 is attached to the outer surface of the window hole 2. A fixing means 7 is provided at the lower part of the side of the frame 1 opposite to the side on which the grip 6 is attached. The fixing means 7 fixes a fixed pedestal 8 to the frame 1, the fixed pedestal 8 has a semicircular notch, and a movable pedestal 9 is pivotally attached to one end by a support shaft 10 so as to rotate laterally. The movable pedestal 9 also has a semicircular notch, and when the pedestals 8 and 9 face each other, the metal seat 38 of the pin insulator 37 can be held between the two notches. A circular hole 11 is formed, and the structure for maintaining this state is such that a tightening bolt 12 is inserted from the frame 1 toward the end of the fixed pedestal 8 on the opposite side from the pivoting part of the movable pedestal 9.
A clamping part 13 is fixed to the tip of the tightening bolt 12, and a hook 14 is attached to the clamping part 13.
The hook 14 is pivoted so as to be swingable laterally, and the hook 14 is biased inward (toward the semicircular notch side) by a spring 15, while the movable base 9
A locking pin 16 is provided upright at the tip.
Therefore, when the open movable base 9 is rotated to close it, the locking pin 16 is engaged with the hook 14,
Therefore, by pulling the locking pin 16 toward the fixed pedestal 8 side using the tightening bolt 12, the hole 11
The seat portion 38 of the pin insulator 37 is held between the pin insulators 37 and attached. In addition, the seat 38 of the pin insulator 37
is slightly larger than the width of the arm 39 of the column to which it is attached, so a presser plate 17 is provided on the back surface of the fixed base 8 to abut against the bottom surface of the seat 38 that protrudes from the arm 39. This presser plate 17
This prevents it from being pulled out from the seat portion 38 and further ensures the fixed state. Further, a handle 18 is provided on the hook 14 in a protruding manner.

The winding means 20 for the filament 19, such as a rope, includes a hook-shaped locking part 21 formed at the tip of the protrusion 3 on the right side in the figure, and a bearing arm 22 fixed in parallel with the protrusion 3 with a space therebetween. A drum 23 with a wire 19 wound thereon is installed between the protrusion 3 and the bearing arm 22, a ratchet wheel 25 is provided on the support shaft 24 of the drum 23, and the tip of the support shaft 24 is shaped like a hexagonal nut. A handle 26 is detachably attached to the square bar, and the drum 23 and ratchet wheel 25 are rotated together with the support shaft 24. A ratchet 27 that engages with the ratchet wheel 25 is attached to the bearing arm 22 and is biased by a spring 28 in the direction of engagement.

Guide means 29 are provided on the protrusion 4 at the center of the frame 1 and the protrusion 5 on the left side in the figure. The guide means 29 is formed by grooved rolls 30, 31 pivotally supported by the respective protrusions 4, 5, and grooves 32, 33 provided on the upper surface of each protrusion 4, 5, and is formed by grooved rolls 30, 31 that are supported by the respective protrusions 4, 5, and grooves 32, 33 provided on the upper surfaces of the respective protrusions 4, 5. The returned filament 19 is pulled out along the grooved rolls 30 and 31, and then reversed and passed through the grooves 32 and 31.
33 to the winding means 20 side, and a loop 34 formed at the tip of the filament 19 is hooked onto the locking portion 21. Note that it is preferable to use a nylon rope as the filament 19. A carabiner 36 is also provided on the rope 35 attached to the frame 1.

To explain the work to be done using the line transfer machine with the above structure, Figure 4 shows the setting work procedure. Before setting the line transfer machine, as shown in the fourth figure A, A wire drawing roller 41 is attached to the arm 39 near the pin insulator 37, and the electric wire 40 is installed along the wire drawing roller 41. Therefore, as shown in the fourth diagram B, first connect the carabiner 36 of the wire transfer machine to the eye bolt 42 that tightens the arm 39 of the wire drawing roller 41, and then hold the grip 6 and remove the most advanced grooved roll 31. The seat portion 38 of the pin insulator 37 is clamped and attached between the fixed base 8 and the movable base 9 of the fixing means 7 while supporting it so as to face the wire drawing roller 41 side. Next, as shown in the fourth diagram C, the filament 19 unwound from the drum 23 is wound back around the electric wire 40, guided along the guide means 29, and the loop 34 at the tip is latched to the locking part 21.

Next, as shown in FIG. 5, the wire transfer work is performed, and as shown in FIG. By rotating the electric wire 19 so as to remove it, the filament 19 is drawn toward the pin insulator 37 along the guide means 29 while holding the electric wire 40, as shown in the fifth diagram B.

After the electric wire 40 has been moved to a predetermined position in this way, the wire 19 is removed from the electric wire 40 as shown in Fig. 6, and the electric wire 40 is fixed to the pin insulator 37. As shown in the figure, the ratchet 27 is disengaged to loosen the filament 19, the electric wire 40 is rested on the frame 1, the loop 34 is removed from the locking part 21, and the filament 19 is removed from the electric wire 40. Next, after removing the handle 26, wrap the winding bind 43 around the electric wire 40 and attach the pin insulator 37.
Fixed to. Hereinafter, the tightening bolt 12 of the fixing means 7
, open the movable pedestal 9 to release the pin insulator 37 and the pin insulator 37, replace it with the adjacent pin insulator 37, and repeat the same operation as described above. When the work is completed, the carabiner 36 can be removed and the transfer machine can be lowered to the ground.

[Effect of idea]

The power distribution line transfer machine according to the present invention is equipped with a fixing means that can be attached to the seat of the insulator, and since the installation position is limited, there is no need to seek space for other installation positions, and moreover, the electric wire can be reliably wired. can be transferred onto the insulator. Furthermore, since the filament is held by hanging on the electric wire and the filament is pulled along the guide means by the winding means, the wire can be transferred by rotating the drum of the winding means, and the operation is easy. It is extremely simple, and even thick and heavy electric wires can be handled easily and reliably by one person in a short time. Furthermore, even after the wires are pulled together and then removed from the filament, the wires can be held on the frame, and the work of attaching them to the insulator becomes easier.
