Description

  The present invention relates to a steadying device for a working gondola.

  Conventionally, in the repair, cleaning, and painting of building walls such as buildings and condominiums, a box-type work gondola on which an operator rides is suspended from a protruding beam attached to a parapet on the roof of the building with a wire rope. It is known that a lower part of a rope is wound around a winch attached to a work gondola, and the work gondola is suspended and supported along a wall surface by rotation of the winch.

  Since such a work gondola is only suspended and supported from the rooftop, when an operator is positioned in the gondola and presses the coating roller against the wall surface to perform a painting operation or the like, A biasing force acts on the work gondola in a direction away from the work, and the work gondola swings away from the wall surface or swings due to wind pressure. As a result, workability deteriorates, and there is a problem that paint or the like scatters downward from the gap between the remote wall surface and the work gondola.

Therefore, as a method of preventing the work gondola from shaking as described above, a suction gondola is provided on the front surface of the work gondola facing the wall surface, and the work gondola is attached to the wall surface by adsorbing the suction face to the building wall surface. A fixing method is known (see Patent Document 1).
JP-A-5-79179

  However, the fixing method of the working gondola by the suction plate as described above may be a building having a wall surface with a wide glass surface or smooth surface, but in a building with an uneven surface such as tiling, There was no surface to adsorb the adsorber, making it difficult to use the adsorber.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a working gondola steadying apparatus for solving the above-mentioned problems.

  In order to solve the above-mentioned problem, the invention according to claim 1 is a working gondola that is suspended and lifted along a wall surface of a building, wherein the steadying rope is supported at the upper end of the building by the upper end of the building, and the lower end. Is supported on the ground side and arranged in the vertical direction, the rear side of the work gondola is passed through the road, and the back side of the work gondola is slidably locked to the steadying rope, The working gondola is provided with an expansion / contraction means that expands and contracts in the front-rear direction.

  The invention described in claim 2 is characterized in that, in the invention described in claim 1, a jack is used as the expansion / contraction means.

  According to the present invention, since the work gondola can be sandwiched between the wall surface of the building and the steadying rope, the work gondola can be easily steady even in a place where the wall surface of the building is not smooth.

When the operator rotates the handle 10e forward and backward by hand, the screw rod rotates, the link opens and closes, and the heads 10b of the jacks 10 and 10 move forward and backward in the direction orthogonal to the building wall surface. is set up. Support members 10d and 10d having support holes 10c and 10c in the vertical direction are mounted on the heads 10b of the jacks 10 and 10, and the anti-sway rope 12 is inserted and locked in the support holes 10c and 10c. It is like that.

  Then, the upper end of the steady rope 12 is fastened and fixed to a fixture 16 attached to the projecting beam 4 fixed to the parapet 2 a, and the insertion holes 9 a and 9 a of the support member 9 and the support hole 10 c of the jack 10 are connected in the path. , 10c, the lower end is fixed to the fixing member 11 installed on the ground, and the steadying rope 12 is stretched in a suspended state on the rear side of the gondola body 3a. Since the fixing tool 16 and the fixing member 11 are arranged on the building side from the rear surface of the gondola main body 3a, the tension of the steady rope 12 can effectively urge the gondola main body 3a in the building side direction. The fixing member 11 may be any member as long as the lower end of the steady-state rope 12 can be firmly held on the ground side, and the steady-state rope 12 may be fixed to the weight 11a mounted on the movable carriage 18. Alternatively, a pile may be driven into the ground and the steadying rope 12 may be fixed to the pile.

  In addition, an opening 3b that is long in the left-right direction is formed in the lower part of the front surface of the gondola body 3a, and the anti-scattering plate 7 is formed in the opening 3b so as to have substantially the same width as the left-right direction of the gondola body 3a. Is provided to be able to advance and retreat in the front-rear direction.

  As shown in FIG. 4, the scattering prevention plate 7 includes a semi-cylindrical flange portion 7 a that opens upward, and a sliding plate 7 b that is connected and fixed to the inner end of the flange portion 7 a. The inner side of the sliding plate 7b is placed on the upper surface of the floor plate 14, and the sliding plate 7b has a plurality of long holes 7c formed in a direction perpendicular to the building wall surface, that is, in the front-rear direction of the gondola body 3a. Yes. Bolts projecting upward from the floor plate 14 of the gondola body 3a are penetrated into the long holes 7c, and the scattering prevention plate 7 is attached by screwing a nut 7e to the bolt and fastening the sliding plate 7b. It can be fixed at a desired position in a direction perpendicular to the building wall. That is, the protrusion amount of the anti-scattering plate 7 with respect to the gondola body 3a can be adjusted. The flange portion 7a is formed of an elastic material such as resin, and the sliding plate 7b is formed of a hard material such as a plywood plate. Further, a cover that covers the long hole 7c and the nut 7e may be detachably provided on the sliding plate 7b.

  Further, a discharge port 7d that discharges the drainage of the cleaning liquid or the like dropped on the anti-scattering plate 7 is formed at one end in the left-right direction of the flange portion 7a, and below the discharge port 7d, A discharge hose 8 communicating with the discharge port 7d is connected, and the lower end of the discharge hose 8 is hung down toward the ground so that the cleaning liquid or paint accumulated in the flange 7a is discharged to a drainage container or the like installed on the ground. It has become.

Next, the working state will be described.
When the work gondola 3 is moved up and down, the winch 6 provided in the work gondola 3 is rotated forward and backward to adjust the amount of the wire rope 5 to move the work gondola 3 up and down along the wall surface. Move to stop at desired position. When the working gondola 3 is raised or lowered, the operator operates the jack 10 so that the head 10b is retracted toward the gondola main body 3a, loosens the tension of the steady-rest rope 12, and the working gondola 3 moves up and down. Make it easy to do.

  When the work gondola 3 is stopped at a predetermined position, the jack 10 is extended so that its head 10b moves forward, and the steady rope 12 on the rear surface of the work gondola 3 is jacked 10. Then, the work gondola 3 is urged toward the building wall surface by pressing against the building wall surface and applying tension to the steadying rope 12. As a result, the front side of the work gondola 3, that is, the flange 7 a that is the tip of the anti-scattering plate 7 connected to the floor plate 14 is pressed against the wall surface of the building. As a result, the work gondola 3 is sandwiched between the building and the steadying rope 12 and the shaking at the stop position is prevented. Moreover, since the front-end | tip of the scattering prevention board 7 press-contacts to a building wall surface, between a building wall surface and the gondola main body 3a is sealed, and it is prevented that a coating material falls and scatters from this. At this time, since the collar portion 7a is formed of an elastic material, the sealing property is good.

  Further, by using the jack 10 as an expansion / contraction means for adjusting the tension of the steady-state rope 12, the operator can rotate the handle 10e of the jack 10 from the inside of the gondola 3 so that the jack 10 can be expanded and contracted. The tension of the rope 12 can be easily adjusted. Further, by using a jack as the expansion / contraction means, the expansion / contraction means 10 can be configured by a commercially available jack.

  Further, when paint or cleaning liquid falls on the scattering prevention plate 7 by painting work or cleaning work, they flow into the flange part 7a and are discharged from the discharge port 7d to a predetermined part, for example, the drainage container 19 through the discharge hose 8. Is done.

  Next, as shown in FIG. 5, a case where there is a protruding wall 20 such as a veranda protruding from the wall surface of the building will be described.

  When the scattering prevention plate 7 is located on the wall portion without the protruding wall 20 as described above, the scattering prevention plate 7 is projected longer than the gondola body 3a as shown by the solid line in FIG. This protruding movement is performed by loosening the nut 7e, pulling out the anti-scattering plate 7, and tightening the nut 7e at a desired protruding position.

  Further, when working with the gondola body 3a raised from the solid line position in FIG. 5 to the broken line position, the scattering prevention plate 7 is moved backward to the gondola body 3a side as shown by the broken line in FIG. The front flange portion 7 a is brought into contact with the protruding wall 20.

  Thus, by providing the scattering prevention plate 7 so as to be able to advance and retreat, there is an effect that the same operation as described above can be performed even in a building with or without the protruding wall 20 as described above.

  The gondola body 3a shown in FIG. 5 also has the structure shown in FIGS. 1 to 4, but these are omitted in FIG.

  In addition, the shape, size, etc. of the frame 13 of the gondola main body 3a in the above-mentioned embodiment are not limited to those shown in FIG.

Further, the number of the steady rest ropes 12 and the number of jacks 10 are set as desired.
The forward / backward moving means for the gondola main body 3a in the scattering prevention plate 7 may be other than the above structure.

  Furthermore, the tip of the scattering prevention plate 7, that is, the flange portion 7a is formed in a straight line with respect to the left-right direction in the above embodiment, but the flange portion 7a is curved in the left-right direction. Also good. That is, you may make it the curved shape where the center part of the left-right direction of the collar part 7a is dented to the gondola main body 3a side. If formed in this way, in the building's veranda, etc., from the design, the collar 7a is also brought into close contact with the wall of which the protruding wall (waist wall) is curved outward, so that the paint or the like falls and scatters. Can be prevented.
