  Further, in this embodiment, a power conversion mechanism 18 that converts the driving force of the driving device 6 (motor 6) into a reciprocating motion is provided, and the driving device 6 and the fitting body 3 are connected via the driving force conversion mechanism 18. Are connected.

  Specifically, a power conversion mechanism 18 is provided on the rotating shaft 17 of the motor 6, and the power conversion mechanism 18 is connected to the fitted body 3.

  In the power conversion mechanism 18, an eccentric cam 19 is connected to the rotating shaft 17 of the motor 6, and a cam receiving cylinder portion 20 into which the eccentric cam 19 can be fitted is formed on the outer peripheral surface of the fitted body 3.

  In addition, the cam receiving tube portion 20 is formed in a horizontally long opening shape having a length in the horizontal direction, and the longer diameter is slightly larger than the diameter of the eccentric cam 19, and the shorter diameter is smaller. The eccentric cam 19 is formed in a shape that is approximately the same diameter as the diameter of the eccentric cam 19.

  The operation of the power conversion mechanism 18 will be described. When the rotating shaft 17 of the motor 6 is rotated 90 ° in the direction of the arrow in the drawing as shown in FIG. 6B from the state of FIG. 6A (phase 0 °) ( When the phase is 90 °), the outer peripheral surface of the eccentric cam 19 that is farthest from the rotating shaft 17 by the rotation of the eccentric cam 19 comes into contact with the inner peripheral surface on the upper side of the cam receiving tube portion 20 in the drawing. 20 (the fitted body 3) is pushed upward by about 3 mm.

  Further, as shown in FIG. 6C, when the rotating shaft 17 rotates 90 ° in the direction of the arrow in the drawing (when the phase is 180 °), the outer periphery of the eccentric cam 19 that pushes up the upper inner peripheral surface of the cam receiving cylinder portion 20. The phase changes so that the surface comes into contact with the inner peripheral surface on the left side of the cam receiving tube portion 20 and the cam receiving tube portion 20 is lowered downward (the fitted body 3 has the same height as the phase 0 °), Subsequently, as shown in FIG. 6 (d), when the rotating shaft 17 rotates 90 ° in the direction of the arrow in the figure (assuming the phase is 270 °), the outer peripheral surface of the eccentric cam 19 located farthest from the rotating shaft 17 is the cam cylinder. The cam receiving cylinder part 20 (the fitted body 3) is pushed downward by about 3 mm by coming into contact with the inner peripheral surface of the part 20 on the lower side in the drawing. In the figure, reference numeral 27 denotes a ball bearing provided on the outer peripheral surface of the eccentric cam 19, and this ball bearing 27 is configured to facilitate the abutting movement between the eccentric cam 19 and the inner peripheral surface of the cam receiving tube portion 20.

The portion 13 is provided on the movable base 2.

  Specifically, it communicates with the disk body 14 concentrically on the upper surface side of the disk body 14 at the lower part of the movable base 2 so as to communicate with the lower part of the penetration fitting part 4 of the fitted body 3. The cylindrical portion 24 is provided so that its cylindrical length is in the vertical direction, and the connecting cylinder 13 is provided in a suspended state in parallel with the through hole 26 at the eccentric position of the bottom of the lower disk body 14. The connecting tube 13 is used as the connecting portion 13.

  Accordingly, as described above, since the fitting body 3 (through fitting portion 4) is cylindrical, the polishing powder generated in the through fitting portion 4 is not easily scattered to the outside. When the suction device 12 is connected and this suction device 12 is operated simultaneously with the reciprocating polishing of the long body 1A by the driving device 6, the polishing powder generated in the through-fitting portion 4 is sucked into the suction device 12. Thus, it is possible to reliably prevent scattering to the outside. In addition, a configuration in which the abrasive powder adheres to the guide frame portion 7 surrounding the fitted body 3 and prevents the reciprocating sliding movement of the fitted body 3 is prevented. Note that a configuration in which the suction device 12 can be directly connected to the movable base 2 may be employed.

Further, in this embodiment, the upper and lower disk bodies 14, the fitting body 3, and the orbiting body 8 of the movable base body 2 are divided into left and right parts at the diameter position in plan view, of each disk body 14 of the upper and lower, one end between the divided portions are connected via a hinge 31, on the other end side fixed, releasable securing means for securing the other end between the connecting state 32 is provided, and the movable base 2 can be opened to the left and right via the hinge 31 by releasing the fixing means 32.

  When the movable base body 2 is opened to the left and right via the hinge 31, the fitted body 3 connected via the guide frame portion 7 is also divided and opened to the left and right. It is configured to be separable.

  Therefore, in this embodiment configured as described above, for example, the movable body 2 and the fitted body 3 are opened via the hinge 31 to separate the circulating body 8 with the polishing body 5, and the separated circulating body 8 is separated. Is attached to the long body 1A, and then the opened movable base body 2 and the fitted body 3 are arranged and closed so as to be fitted onto the long body 1A from above the circulating body 8, and this closed state is fixed. By fixing with the means 32, this apparatus can be attached to the elongate body 1A. That is, for example, the present embodiment is configured so that it can be easily attached to a long body 1A such as a hanger rope 1A whose upper and lower ends are connected to other members and are not free.

  Next, the substrate adjustment work of the hanger rope 1A using the present apparatus will be described with reference to FIGS.

  In this embodiment, the apparatus is attached to the lifting gondola 25 via the mounting bracket 33, and the apparatus moves up and down along the length direction of the hanger rope 1A in conjunction with the lifting and lowering movement of the lifting gondola 25. I am doing so. Further, the drawing shows a case where two hanger ropes 1A that are installed in parallel by attaching two of the devices to the lifting gondola 25 are adjusted simultaneously.

  The device is attached (fitted) to the hanger rope 1A, the suction device 12 is connected to the connecting portion 13, and the driving device 6 and the suction device 12 are driven.

  Then, the fitted body 3 reciprocally slides along the long body 1 with respect to the movable base 2, and the abrasive body 5 that presses against the outer peripheral surface of the long body 1 by the reciprocating slide of the fitted body 3 is the long body. The base material of the long body 1 is adjusted by reciprocating the outer peripheral surface of 1.

  For example, the work start point is the upper end of the hanger rope 1A, and the lifting gondola 25 is slowly moved down to the lower end of the hanger rope 1A at the same time as the work starts to adjust the base of the hanger rope 1A.

  In the present embodiment, the present apparatus is attached to the lifting gondola 25, and the lifting gondola 25 is controlled to move up and down to move the apparatus along the long body 1A. The apparatus may move downward with respect to the long body 1A under its own weight.

  A second embodiment of the present invention will be described with reference to FIG.

  The present embodiment is applied to a steel pipe 1B (hereinafter referred to as a long body 1B) of a steel tower.

  Specifically, the configuration of the polishing body 5 is different from that of the first embodiment.

  The polishing body 5 of the present embodiment employs a polishing sheet 34 having elasticity, and a cylindrical sheet support portion 35 in which the polishing sheet 34 is protruded from the inner peripheral surface of the through-fitting portion 4 of the fitting body 3. I support it.

  Further, the polishing sheet 34 is supported by the support portion 33 so as to be in pressure contact with the entire outer periphery of the long body 1B, and the entire periphery of the outer periphery of the long body 1B is uniformly reciprocally polished by the polishing sheet 34. It is configured.

  In the present embodiment, the elasticity of the polishing sheet 34 functions as the pressure urging means 9.
