It is.

  For example, the gondola 10 with a curing device is wound around a winder 5 provided on a gondola 11 as a work cage 4 and is wound around a wire rope 3 that is fixed on the rooftop of the structure 1 and suspended along the side surface 2. It is installed in a gondola as a work cage 4 that is moved up and down while moving, to prevent falling or scattering.

  The curing device 20 of the gondola 10 with the curing device is installed so as to cover a range where the work can be performed from the gondola 11 using the work cage 4 stopped at a position where the side surface 2 of the structure 1 is located. And a fixed fixed curing frame member 21, 22, 23 is connected to the upper part of the handrail 12 so as to open only the front surface on the side surface 2 side of the structure 1 and to cover the left and right surfaces and the rear surface. A curling member 24 such as a net is attached using a pillar or a handrail of 11 itself, and movable side curing frame members 25 and 25 and a bottom curing member 26 are installed above the handrail 12 of the front opening. Configured. Note that a curing member 24 such as a net is attached to the front surface of the gondola 11 itself using a support column or a handrail.

  The work cage 4 constituting the gondola 11 is attached with connecting struts 27 through the holes formed in the handrail 12 at the four corners, and the upper end portions of the four connecting struts 27 are two types of horizontal connecting members 28, long and short. A rectangular frame corresponding to the height of the work range is formed on the three side surfaces of the work cage 11 by being connected at 29, and left and right fixed curing frame members 21 and 22 and a rear fixed curing frame member 23 are configured. Then, a curing member 24 such as a net is attached by integrating the left and right fixed curing frame members 21 and 22 and the rear fixed curing frame member 23 and the work cage 4 itself.

  Further, in this curing device 20, since two movable side curing frame members 25, 25 are installed, two rotations are provided between the handrail 12 and the horizontal connecting member 28 inside the left and right ends of the work cage 4. Support columns 30 are attached with bolts, pins, etc., and side curing frame members 25, 25 that are rectangularly framed are attached to the respective rotation support columns 30 via hinges 31, and are perpendicular to the side surface 2 of the structure 1. In this way, it is possible to open the door in a state where it is opened 90 degrees and closed inward in a plane parallel to the front surface of the work cage 4. A curing member 24 such as a net is attached to the side curing frame members 25, 25.

  Further, an elastic plate member 32 such as rubber is attached to the front end edge of the side curing frame members 25, 25 so that the adhesion to the side surface 2 of the structure 1 can be improved.

  Further, the bottom curing member 26 of the curing device 20 is provided between the two left and right side curing frame members 25, 25, and is attached to three places of the handrail 12 of the work cage 4 as shown in FIG. 33 can swing between a state where it projects forward and a state where it closes so as to jump up.

  The bottom curing member 26 is fixed with bolts and nuts so as to surround the handrail 12 from above with the support bracket 33, and a fixed frame 35 is attached to the rotating shaft 34 at the top of the support bracket 33, and slightly protrudes forward. The tip is high and the work cage 4 side is low. A slide frame 36 is disposed inside the fixed frame 35, and two guide bolts 38 penetrating the guide holes 37 of the fixed frame 35 are screwed into the slide frame 36 so that the slide frame 36 can be expanded and contracted within the range of the guide holes 37. For example, it can be expanded and contracted by about 150 mm.

  A metal curing plate 39 is attached to the upper surface of the slide frame 36, an elastic plate member 32 such as rubber is attached to the distal end edge portion, and a long elastic plate member 32 such as rubber is attached to the base end edge portion. It hangs down in the work cage 4. This improves the adhesion with the side surface 2 of the structure 1 by the elastic plate 32 at the distal end edge, and is long even if the bottom curing member 26 is extended so as to protrude forward by the elastic plate 32 at the proximal edge. By positioning the elastic plate member 32 in the work cage 4, it can be completely cured without generating a gap, and can be cured so as to protrude below the veranda 6 of the structure 1.

  Further, in this gondola 10 with a curing device, a curing member 24 such as a net is attached to the front surface of the work cage 4 itself and the outer portions of the movable side curing frame members 25, 25. Accordingly, the work range from the work cage 4 surrounded by the movable side curing frame members 25 and 25 and the movable bottom curing member 26 that closes the bottom thereof can be completely cured, and the work cage 4 other than the front opening can be cured. Is also cured by the curing member 24.

  In the gondola 10 with the curing device configured as described above, after the working cage 4 is moved up and down to a predetermined working position, the movable side curing frame members 25 and 25 are opened to the outside, and the bottom curing member 26 is interposed therebetween. By setting it down, the work range of the front surface of the work cage 4 can be cured. For example, even when repairing the side surface 2 of the structure 1, the shavings on the wall surface are dropped or scattered. It is possible to prevent scraping and to collect the shavings and the like in the work cage 4 by causing the bottom curing member 26 after the work.

  Further, when the work cage 4 is moved by an officer or the like, after the bottom curing member 26 is flipped up, the side curing frame members 25, 25 on both sides are closed inward so that the normal work can be performed. It can be made the same size as the cage 4, and can move up and down smoothly even if it is a structure with unevenness on which the veranda 6 is installed.

  Further, in the gondola 10 with the curing device, the bottom curing member 26 is configured to be expanded and contracted by the slide frame 36, so that the surface such as the veranda 6 (side surface of the structure) and the corners of the front and lower surfaces are repaired. When performing, as shown in FIG. 1, it is possible to install the bottom curing member 26 so as to protrude below the lower surface of the veranda, thereby creating a gap even in a portion where the side surface of the structure 1 does not exist. And can work in a cured state.

  Moreover, in this curing device 20, although the part surrounded by the movable side curing frame members 25, 25 and the movable bottom curing member 26 that closes the bottom thereof can be opened, other parts of the work cage 4 can be opened. Since it is in a state completely covered with the curing member 24, it is difficult to get on and off the work cage 4, so an opening 40 is formed in the curing member 24 of the fixed curing frame member 22 as shown in FIG. The fastener 41 can be opened and closed.

  Thereby, boarding / alighting becomes easy by opening the opening part 40, and a curing state can be maintained by closing with the fastener 41. FIG.

  Further, in the gondola 10 with the curing device, the work cage 4 is suspended by the two wire ropes 3 and 3 wound around the two winders 5 mounted in the work cage 4. The position of the center of gravity when the work is performed in the vicinity becomes the vicinity of the handrail 12, and when the worker moves to the front side of the work cage 4, the center of gravity is tilted forward, so as shown in FIG. A suspension point support member 42 that suppresses the inclination is provided, and the inclination is suppressed by supporting the upper portions of the wire ropes 3 and 3.

  The suspending point support member 42 is provided with a fixed frame 43 and an open / close frame 44 that can be opened and closed around a vertical axis. Support rollers 45 and 45 are attached to the fixed frame 43 and the open / close frame 44, respectively. The wire ropes 3 and 3 are sandwiched from the front and rear of the wire 4, and the wire ropes 3 and 3 are closed and closed so that the open / close frame 44 can be fixed with bolts. The suspending point support member 42 is attached to the uppermost portion of the curing device 20 with two arms 46 and a reinforcing beam 47 connected to the horizontal connecting member 28.

  Thereby, the fulcrum of the front and rear inclination of the work cage 4 becomes the position of the support rollers 45 and 45 with which the wire ropes 3 and 3 are in contact, and the inclination can be greatly reduced. It is possible to improve the adhesiveness without damaging the adhesiveness.
