  The clamper 14 supports the ground portion 2 of the broken pole, and is attached to the distal end portion of the arm 12 so as to be rotatable and detachable. Since such a clamper 14 supports the ground portion 2 of the broken electric pole, a contact member 14a that contacts the ground portion 2 and a fastening member 14b that fastens the pair of contact members 14a so as to sandwich the ground portion 2 of the broken electric pole. And a shaft 14c attached to the arm 12.

  In addition, the abutting member 14a includes a fixed plate 14d longer than the outer diameter of the ground portion 2 of the broken power pole, and projecting portions 14e projecting at two locations on the inner surface where the pair of fixed plates 14d face each other. Yes. A long hole 14f is formed at both ends of the fixed plate 14d, and the fastening member 14b is bridged between the long holes 14f of the pair of fixed plates 14d, so that the fixed plate 14d is fixed in a state of sandwiching the ground portion 2 of the broken power pole. To do.

  The fastening member 14b is composed of, for example, both nut bolts as shown or a combination of bolts and nuts. In any case, by forming the long hole 14f in the fixing plate 14d, the position where the fastening member 14b is bridged is adjusted according to the diameter of the ground portion 2 of the broken pole.

  The two protruding portions 14e are projected on the inner surface of the fixing plate 14d so as to abut the ground portion 2 of the broken power pole in the length direction, and a part of the outer periphery of the ground portion 2 is between the protruding portions 14e. It is in a state where it can be fitted. The protruding portion 14e is formed longer than the width of the fixed plate 14d so that the ground portion 2 of the broken power pole is stably supported.

  The shaft 14c is provided outwardly at the center of the fixing plate 14d, and is detachably attached to a fixture 17 provided at the tip of the arm 12. That is, the clamper 14 is rotatable about the shaft 14c.

  Further, a tow hook 18 is attached to the tip end side of the clamper 14. A wire, rope, chain, or the like is hooked on the hook 18.

  Then, as shown in FIGS. 1 to 3, the floor plate 20 that slides the ground portion 2 of the broken power pole is folded upward by bending both edges of the belt-like flat plate with a width narrower than the diameter of the ground portion 2. A bar-shaped reinforcing member 21 is fixed inside the corner. The bottom edge of the ground portion 2 moves on the bent edge of the floor plate 20 while making point contact.

  Even if the lower end edge of the ground part 2 of the broken pole is uneven, the both end edges of the flooring plate 20 bite into the unevenness, the grounding part 2 is in a stable posture, and the flat part of the flooring plate 20 is Move without hurting. Moreover, although the load of the ground part 2 of a broken telephone pole is applied to the both ends edge of the flooring board 20, this both ends edge is not deformed by the reinforcing material 21. In addition, the floor plate 20 may use a flat plate that is not bent at both edges according to the use situation.

  In addition, an arc-shaped concave portion 22 for fitting the underground portion 3 of the broken power pole is formed at one end portion of the floor plate 20, and a hook 23 for hooking one end portion of the temporary support wire 5 is attached to the other end portion. ing. The other end of the temporary support line 5 is attached to the upper part of the ground part 2 of the broken power pole so that the ground part 2 does not fall toward the underground part 3. Therefore, the temporary support line 5 is extended as the ground portion 2 moves toward the underground portion 3 so that the ground portion 2 can move toward the underground portion 3 while maintaining a substantially vertical posture. ing.

  And although the track plate 30 is formed in the width | variety which the wheel 15 with which the base 11 was equipped rides, the both edges may be bend | folded upward so that the wheel 15 may not take off. The track plate 30 is used when the ground is muddy or a lot of gravel is scattered, and is not essential.

  Next, with reference to FIGS. 4 to 10, a first method for temporarily restoring a broken power pole in a state where a vehicle or the like collides with the power pole and the power pole is cut off at the ground using the temporary restoration device for the broken power pole will be described. The description will be given with reference.

  First, as shown in FIG. 4, in a state where the ground part 2 of the broken power pole is displaced and separated from the underground part 3 and the reinforcing bar 1 is bent and exposed, the support column 4 is placed in the hollow hole of the underground part 3. The column 4 is erected by insertion. A support member 4 a that is joined to the ground portion 2 of the broken pole and a hook 4 b that hooks a chain 6 that binds the ground portion 2 are attached to the support column 4.

  And the clamper 14 is fixed to the lower end part of the ground part 2 of a broken telephone pole. That is, the ground portion 2 of the breakable utility pole is slightly fitted between the protruding portions 14e protruding from the fixing plate 14d of the clamper 14, is sandwiched between the pair of fixing plates 14d and 14d, and the shaft 14c faces in the opposite direction. In the state, it is fastened by the fastening members 14b and 14b. Furthermore, when the ground is muddy or a lot of gravel is scattered, the track plates 30 are laid on both sides of the ground part 2 and the ground part 3 as indicated by phantom lines. Hereinafter, the case where the raceway plate 30 is laid is described specially.

  Next, as shown in FIG. 5, the jack 10 supports the ground portion 2 of the broken power pole by attaching the shaft 14 c of the clamper 14 to the tip of the arm 12 with the fixture 16. The base 11 to which the arm 12 is attached is set on the ground so that the arm 12 is parallel to a line connecting the ground portion 2 and the underground portion 3 of the broken power pole. Therefore, if the direction in which the clamper 14 sandwiches the ground part 2 of the broken power pole is inappropriate, the direction is adjusted. Moreover, the arm 12 is set to a horizontal posture or a direction close to the horizontal posture.

  Next, as shown in FIG. 6, the reinforcing bar 1 exposed between the ground part 2 and the underground part 3 of the broken pole is excised. However, the rebar 1 may be removed before the clamper 14 is fixed to the lower end of the ground portion 2 of the broken pole. Then, the lever 13 is operated to raise the clamper 14 by a jacking action, thereby lifting the ground portion 2 of the broken power pole and providing a space between the lower end edge of the ground portion 2 and the ground.

  Next, as shown in FIG. 7, a floor plate 20 is laid from the lower side of the ground part 2 of the broken pole to the underground part 3. Therefore, the clamper 14 lifts the ground portion 2 so that a space in which the floor plate 20 can be laid is provided.

  Next, as shown in FIG. 8, the lever 13 is operated, and the clamper 14 is lowered by setting the arm 12 in a horizontal posture. Since the upper end edge of the base 11 is formed to be forwardly lowered, the arm 12 takes a horizontal posture without the clamper 14 colliding with the upper end edge of the base 11. In this way, the ground portion 2 of the broken utility pole supported by the clamper 14 is lowered, and the lower end edge is placed on the floor plate 20.

  At this time, since the lever 13 is attached to each base 11, the attitude of the ground portion 2 can also be adjusted by adjusting the inclination angle of each arm 12. Moreover, the temporary branch line 5 is attached to the upper part of the ground part 2 and the hook 23 of the floor board 20 as needed.

  Next, as shown in FIG. 9, the ground part 2 of the broken pole is moved toward the underground part 3 while its lower edge slides on the floor plate 20. The ground portion 2 can hook a wire (not shown) on the hook 18 of the clamper 14 and move the wire toward the underground portion 3 by using a drawing tool, an automobile, or the like, or only by hand.

  Further, the two jacks 10 support the ground part 2 of the broken power pole, and the wheel 15 moves toward the ground part 3 of the broken power pole while rolling on the ground, so that the load of the ground part 2 of the broken power pole is spread on the floor plate. In addition to 20, it is also distributed to the wheels 15 of the base 11, and the ground portion 2 moves smoothly on the floor plate 20 toward the underground portion 3. When the track plate 30 is laid, the wheels 15 of the jacks 10 roll on the track plate 30 smoothly. However, since it is dangerous for each jack 10 to move at a higher speed, the raceway plate 30 is provided with a resistance that can move safely and smoothly.

  In any case, since the frictional force is generated when the lower edge of the ground portion 2 of the broken power pole slides on the floor plate 20, the ground portion 2 does not move toward the underground portion 3 with momentum. Moreover, the ground part 2 does not fall toward the underground part 3 during movement by the temporary support line 5 attached to the upper part of the ground part 2 of the broken electric pole and the hook 23 of the floor plate 20.

  Next, as shown in FIG. 10, when the ground portion 2 of the broken power pole comes into contact with the receiving member 4 a of the support column 4, the lever 13 is operated to slightly lift the ground portion 2. Then, the floor plate 20 is removed from below the ground portion 2. Further, since the ground portion 2 is rotatably supported by the clamper 14, the ground portion 2 is lowered onto the ground in a direction along the support column 4. That is, when the support column 4 stands in the vertical direction, the ground portion 2 is also corrected to a vertical posture, and when the support column 4 is slightly tilted, the ground portion 2 is also slightly tilted along the support column 4.

  Finally, as shown in FIG. 11, when the ground portion 2 is tied to the support column 4 by the chain 6 or the like using the hook 4b of the support column 4, a series of operations is completed.

  Next, a second method for temporarily recovering the broken utility pole with the utility pole cut off at the ground will be described with reference to FIGS. 4 to 8, 12, 13 and 11. This second method is characterized in that the base 11 is not used to move the ground part 2 of the broken pole to the underground part 3.

  That is, as shown in FIG. 4, the column 4 is erected on the underground part 3 of the broken electric pole, while the clamper 14 is fixed to the ground part 2 of the broken electric pole. Then, the shaft 14c of the clamper 14 is attached to the arm 12 of the base 11 as shown in FIG. 5, the arm 12 is inclined as shown in FIG. 6, and the ground portion 2 is lifted by raising the clamper 14, and FIG. The floor plate 20 is laid as shown in FIG. During this time, the exposed reinforcing bar 1 is excised. Thereafter, the arm 12 is set in a horizontal posture, and the lower end edge of the ground portion 2 of the broken power pole is placed on the floor plate 20 by lowering the clamper 14 as shown in FIG.

  Then, unlike the first method, the second method removes the clamper 14 from the arm 12 as shown in FIG. The pair of clampers 14 keeps the ground portion 2 of the broken power pole fixed. Then, a wire (not shown) is hooked on the hook 18 of the clamper 14, and the ground part 2 of the broken power pole is moved toward the underground part 3 by using a drawing tool, an automobile, or the like alone. The ground portion 2 of the broken power pole is in a state of being released from the base 11 and the arm 12, and the lower end edge of the ground portion 2 is in point contact with the bent end edge of the floor plate 20 at four points, and is in surface contact. The frictional resistance is smaller than that when the ground part 2 is moving, and the ground part 2 moves toward the underground part 3 smoothly.

  Then, as shown in FIG. 13, when the ground portion 2 approaches the support column 4, the shaft 14 c of the clamper 14 is attached to the arm 12 of the base 11. Then, by operating the lever 13, the arm 12 is inclined and the clamper 14 is lifted to lift the ground portion 2 of the broken utility pole and remove the floor board 20. And the attitude | position is corrected so that the ground part 2 of a broken telephone pole may follow the support | pillar 4, and the ground part 2 is dropped on the ground with the arm 12 as a horizontal attitude.

  Finally, as shown in FIG. 11, when the ground portion 2 is tied to the support column 4 by the chain 6 or the like using the hook 4b of the support column 4, a series of operations is completed.

In addition, this invention can be variously changed within the range of the invention specific matter described in the claim, without being limited to the said embodiment. For example, in the first method for temporarily restoring the broken power pole, when the arm 12 can move the jack while supporting the ground portion 2 of the broken power pole in a stable posture, or the ground portion 2 of the broken power pole. When using a device (not shown) that moves while suspended, the ground part 2 of the broken electric pole can be moved toward the underground part 3 of the broken electric pole without using the floor plate 20. In this case, a gap is generated between the ground portion 2 of the broken power pole and the ground, and the ground portion 2 of the broken power pole is moved up toward the underground portion 3 of the broken power pole. Or you may make it move to the underground part 3 of a broken electric pole in the state in which the ground part 2 of a broken electric pole slightly rubs the ground.
In the first method for temporarily restoring the broken utility pole, the clamper 14 of the jack 10 may be fixed to the arm 12 so that it cannot be removed. Moreover, in the 2nd method of temporarily recovering a broken utility pole, it is not necessary to provide the wheel 15 in the base 11. FIG.
