本考案は、電柱の支線ロツドを地表面下で切断
撤去する装置に関するものである。[Detailed Description of the Invention] The present invention relates to a device for cutting and removing branch wire rods of utility poles below the ground surface.

dよりなつている。 As shown in Figure 15, the branch line of a utility pole is called a branch rod, which has an upper part b between the utility pole a and the above-ground part, and the lower part goes underground through this upper part b and thimble c, and a branch line block e is attached to the lower end. The lower part d is longer.

かつた。 Some or all of the overhead lines are no longer needed,
If the route of the overhead line is changed, the utility poles and the branch wires that support them will no longer be needed and will need to be removed. The conventional method for removing such a branch line is to remove the branch line block e as well. Therefore, the ground had to be excavated over a wide area and to a great depth, and it took a lot of labor and time to remove the excavation work and to fill in the wide and deep holes left in the ground after the removal. Particularly when a branch line is buried under a paved road, it is necessary to remove a large area of pavement, and the area required to backfill and resurface the holes after removal is large, resulting in additional labor, time and effort. It cost a lot of money.

て詳細に説明する。 In view of the above points, the present invention cuts the branch rod at the required depth underground by only slightly excavating the area where the branch line penetrates, and then extends the branch rod and branch block below the cut point underground. By removing the upper branch wire rod from the cut point, the labor, time, and cost of removing the branch wire and backfilling the hole in the ground are significantly reduced, and work efficiency is improved. The present invention provides a branch line rod cutting and removing device, which will be described in detail below with reference to the drawings.

て完了する。 Next, to explain how to use the device of the present invention, first, as shown in Fig. 15, the ground where the branch rod d is inserted into the ground is slightly dug, and the branch rod d is connected to the thimble c using an appropriate tool. Cut it right at the bottom. After that or in advance, attach adapter 2 to main cylinder 1.
Screw it in and fix it firmly with the screws screwed through the screw holes 14 and 11, and insert the connected body of the main tube 1 and the adapter 2 so as to match the angle of the support rod d. When the tip of the adapter 2 reaches the hole dug in the ground, turn the handle 33 of the jack 27 of the holder 5 held near the main barrel 1 to open the diamond-shaped jack 27 and remove the main barrel. The housing table 30 is tilted and adjusted to the same angle as the angle formed by the connecting body of the main cylinder 1 and the adapter 2 with the ground surface, and the main cylinder housing table 30 is supported in close contact with this connecting body. Next, the driving rod 4 is inserted into the main cylinder 1 by passing the branch rod d through the branch rod insertion hole 19 of the head 18 with the striking head 18 facing down. Next, while holding the upper end of the branch rod d, pull up the driving rod 4 by holding its grip 20 and lower it down along the branch rod d, so that the tip of the striking head 18 is attached to the base end of the adapter 2. It is made to collide with the impact receiving surface 12. The impact at that time drives the tip of the adapter 2 into the ground. By repeating this operation, the adapter 2 is gradually driven deeper into the ground. Once the connected body of main barrel 1 and adapter 2 becomes able to stand on its own during this process, remove the holder 3 to make the driving operation easier, and read the scale and numbers attached to adapter 2 and main barrel 1. When the connecting body is driven to the required depth, the driving rod 4 is pulled out, and the cutting tool 5 is inserted into the main cylinder 1 while the milling cutter 49 is moved to one side instead. At that time, the guide rail receiving grooves 41 on both sides of the frame 40 are connected to the guide rails 1 on both sides of the main cylinder 1.
6 and insert it until one end of the frame 40 comes into contact with the stopper 17. At that time, the milling cutter 49 is located close to the impact receiving surface 12 of the adapter 2, and the electric drill mounting end 5 of the rotary shaft 55
7. The knob 60 of the milling cutter moving rod 59 is protruded from the top of the main barrel 1. Next, the electric drill attachment end 57 is attached to the electric drill. At this time, the branch rod d is placed in the center of the main cylinder 1, and the milling cutter 49 is rotated. While supporting the branch line rod d with your hand, pick it 6.
0 to bring the milling cutter 49 closer to the branch rod d, bring it into contact with it, and begin cutting the branch rod d. Further, gradually turn the knob 60 to cut and cut the branch wire rod d. If it is cut, take out the cut branch rod d. Thereafter, the cutting tool 5 is pulled out from inside the main cylinder 1. Next, in order to pull out the connected body of the main cylinder 1 and the adapter 2 that have been driven into the ground from the ground, the auxiliary cylinder 6 is screwed into the upper part of the main cylinder 1 and attached.
Next, place the driving rod 4 parallel to the outside of the auxiliary cylinder 6, position it so that the cylindrical grip part 20 is inserted between both removal protrusions 6', 6' at the end of the auxiliary cylinder 6, and then The inner end surface of the head 18 is the removal protrusion 6'.
, and then pull the cylindrical grip part 20 strongly. Due to the impact force at that time, the connected body of the main cylinder 1 and the adapter 2, which has been driven into the ground, moves to the ground surface. By repeating this operation, the connected body will gradually come out. Main tube 1 and adapter 2
Also, when the connecting body of the auxiliary cylinder 6 becomes unable to stand on its own, it can be removed by hand. Also, if you fill in the hole in the ground after pulling it out, all branch line rod removal work will be completed.
