  Here, as will be described later, the scaffold 3 is suspended immediately below the first long shackle hangers 331 and the second long shackle hangers 332 for hangers.

It should be noted that the inclination angle adjustment driving wheel 340 provided in the scaffold angle adjusting device 10a and the gradient correction driving wheel 340 provided in the scaffold angle adjusting device 10b may be interlocked to adjust the inclination angle.

Next, an example of a control block diagram when the mobile scaffold device 1 according to the present embodiment can adjust the inclination angle of the scaffold 3 by the control button is shown in FIG.
As shown in FIG. 4A, the mobile scaffold device 1 includes a control unit 500, a first adjustment button 510, a second adjustment left button 521, a second adjustment right button 522, and a first adjustment drive unit. 540, a second adjustment left drive unit 551, and a second adjustment right drive unit 552.

  Based on the signals input from the first adjustment button 510, the second adjustment left button 521, and the second adjustment right button 522, the control unit 500 controls the first adjustment drive unit 540, the second adjustment left drive unit 551, and the second adjustment button. The adjustment right drive unit 552 is controlled.

  The first adjustment button 510 is used to input an instruction to change the tilt angle adjusted by the tilt angle adjusting device 200 of the scaffold angle adjusting device 10 a and the scaffold angle adjusting device 10 b, and outputs the input signal to the control unit 500. .

Note that the second adjustment right button 522 is a button for moving, stopping, and stopping the gradient correction drive vehicle 340 of the scaffold angle adjustment device 10b, and the first wire of the gradient correction drive vehicle 340. Buttons are provided for extending, contracting, and stopping the fastener 341 and the second wire fastener 342.

  The first adjustment button 510, the second adjustment left button 521, and the second adjustment right button 522 are provided on a control panel (not shown).

  The first adjustment drive unit 540 is controlled by the control unit 500, and the first height adjustment chain block 231 and the second height adjustment chain of the inclination angle adjustment device 200 in the scaffold angle adjustment device 10a and the scaffold angle adjustment device 10b. The motor provided in the block 232 is driven to adjust the lengths of the load chain 231c and the load chain 232c. The first adjustment driving unit 540 receives the input of the first adjustment button 510, and includes a height adjustment chain block 230 of the scaffold angle adjustment device 10a and a height adjustment chain block 230 of the scaffold angle adjustment device 10b. Operate both in conjunction.

  The second adjustment left drive unit 551 is controlled by the control unit 500 and drives the gradient correction drive vehicle 340 of the gradient correction device 300 in the scaffold angle adjustment device 10a. The second adjustment left drive unit 551 drives the gradient correction drive vehicle 340 of the scaffold angle adjustment device 10a by the input of the second adjustment left button 521.

  The second adjustment right drive unit 552 is controlled by the control unit 500 and drives the gradient correction drive vehicle 340 of the gradient correction device 300 in the scaffold angle adjustment device 10b. The second adjustment right drive unit 552 drives the gradient correction drive vehicle 340 of the scaffold angle adjustment device 10b by the input of the second adjustment right button 522.

  With such a configuration, the mobile scaffold device 1 operates the tilt angle adjusting device 200 in the scaffold angle adjusting device 10a and the scaffold angle adjusting device 10b by operating the first adjustment button 510, and the scaffold angle adjusting device 10a and the scaffold angle. The length of the load chain 231c and the load chain 232c in the adjusting device 10b can be adjusted, and the primary adjustment of the inclination angle of the scaffold 3 can be performed.

In the moving scaffold device 1, the gradient correction device 300 in the scaffold angle adjustment device 10a is activated by the operation of the second adjustment left button 521, and the gradient correction drive vehicle 340 of the scaffold angle adjustment device 10a performs the inclination angle adjustment. By operating the second adjustment right button 522, the gradient correction device 300 in the scaffold angle adjustment device 10b is activated, and the gradient correction drive vehicle 340 of the scaffold angle adjustment device 10b adjusts the inclination angle, thereby adjusting the inclination angle of the scaffold 3. Secondary adjustment can be made.
Thereby, the scaffold 3 can be made horizontal.

Next, an example of installing and using the scaffold 3 will be described.
As shown in FIG. 5 (a), first, the moving scaffold device 1 is moved to the lower part of the structure using the scaffold 3, and the scaffold angle adjusting device 10a is disposed on the left traveling rail 2a, and the right traveling rail 2b. The scaffold angle adjusting device 10b is installed.

  Next, by changing the lengths of the load chain 231c of the first height adjusting chain block 231 and the load chain 232c of the second height adjusting chain block 232 of the inclination angle adjusting device 200, the scaffold 3 Adjustment is made so that the inclination angle in the extending direction of the traveling rail 2 becomes horizontal. In the gradient correction apparatus 300, the gradient correction drive wheel 340 is moved to the initial position.

  Further, since the height adjusting chain block 230 of the scaffold angle adjusting device 10a and the height adjusting chain block 230 of the scaffold angle adjusting device 10b are interlocked, for example, the height adjusting chain of the scaffold angle adjusting device 10a is used. By simply adjusting the block 230, the scaffold 3 can be roughly leveled.

  Furthermore, if the scaffold 3 is not horizontal in this state, the height adjusting chain block 230 of the scaffold angle adjusting device 10a and the height adjusting chain block 230 of the scaffold angle adjusting device 10b are not linked. The scaffold 3 is adjusted to be horizontal by changing the length of one or both of the load chain 231c and the load chain 232c. As described above, the tilt angle adjusting device 200 performs the primary adjustment of the tilt angle with respect to the scaffold 3.

  When the scaffold 3 becomes horizontal in this way, the maintenance work of the structure is performed on the scaffold 3. Then, when the work at this place is completed, the moving scaffold device 1 is moved together with the scaffold 3 along the traveling rail 2 by the traveling drive vehicle 100 and moved to the next working position.

  At the next work position, since the scaffold 3 is adjusted horizontally by the tilt angle adjusting device 200 of the mobile scaffold device 1 at the previous work position, the initial work position, or the like, the scaffold 3 is considered to be approximately horizontal. It is done.

  However, it is also conceivable that the inclination of the traveling rail 2 changes due to the movement of the work position. That is, an inclination angle may occur due to movement. FIG. 5B is an example in the case where the traveling rail 2 is inclined (FIG. 5B is an extreme example in order to represent the features of the invention). Therefore, when the scaffold 3 is inclined, the scaffold 3 is corrected horizontally by using the gradient correcting device 300 while the adjustment of the inclination angle adjusting device 200 is fixed by the moving scaffold device 1.

  Here, by moving the position of the gradient correction driving vehicle 340 of the gradient correction device 300, the inclination in the extending direction of the traveling rail 2 of the scaffold 3 can be corrected horizontally. For example, if the traveling rail 2 is higher on the first upper trolley 211 side and lower on the second upper trolley 212 side, the gradient correction drive vehicle 340 of the gradient correction device 300 is moved to the first correction trolley 321 side. Accordingly, the distance from the first correction trolley 321 to the first hanger suspension part 333 of the hanger jack 330 is set to be larger than the distance from the second correction truck 322 to the second hanger suspension part 334 of the hanger jack 330. By making it longer, the scaffold 3 can be made horizontal. Thus, the gradient correction apparatus 300 performs secondary adjustment of the inclination angle with respect to the scaffold 3.

Next, the case where the right traveling rail 2b is higher than the left traveling rail 2a will be described.
FIG. 6A shows an example in which the right traveling rail 2b is higher than the left traveling rail 2a.

In this case, as described above, first, the scaffold 3 is horizontally corrected using the gradient correcting device 300 while the adjustment of the inclination angle adjusting device 200 is fixed by the moving scaffold device 1.
Next, the first wire fastener 341 and the second wire fastener 342 wound around the gradient correction drive wheel 340 are connected to the left traveling rail 2a and the right using the gradient correction device 300 of the scaffold angle adjusting device 10b. Pull out the difference in height from the traveling rail 2b.

  Accordingly, the distance from the first correction trolley 321 of the scaffold angle adjusting device 10a to the first hanger hanging portion 333 of the hanger jack 330, and the second hanger hanging portion of the hanger jack 330 from the second correction truck 322. The distance from the first correction truck 321 of the scaffold angle adjusting device 10b to the first hanger suspension portion 333 of the hanger jack 330, the second correction truck 322 to the hanger first of the hanger jack 330 than the distance to 334. 2 The distance to the suspended portion 334 can be increased by the difference in height between the left traveling rail 2a and the right traveling rail 2b, and the scaffold 3 can be leveled.

Next, the case where the left traveling rail 2a and the right traveling rail 2b are not parallel will be described.
FIG. 6B shows an example in which the left traveling rail 2a and the right traveling rail 2b are not parallel but twisted or curved, for example.

In this case, as described above, first, the scaffold 3 is horizontally corrected using the gradient correcting device 300 while the adjustment of the inclination angle adjusting device 200 is fixed by the moving scaffold device 1.
Next, the wire rope 351 extending in the direction of the scaffold 3 from the first correction truck 321 and the scaffold 3 from the second correction truck 322 using the gradient correction apparatus 300 of the scaffold angle adjustment apparatus 10a and the scaffold angle adjustment apparatus 10b. The length of the wire rope 352 extending in the direction is changed to correct the scaffold 3 horizontally.

  As described above, the moving scaffold device 1 can keep the scaffold 3 horizontal even if the inclination of the target structure changes and the left traveling rail 2a and the right traveling rail 2b change to any angle. .

Next, an example when the tilt sensor 402 is provided in the mobile scaffold device 1 will be described.
FIG. 7 is a perspective view of the mobile scaffold device 1 a provided with the tilt sensor 402. In addition, since the moving scaffold apparatus 1a is the structure similar to the said moving scaffold apparatus 1 except having provided the inclination sensor 402, description is abbreviate | omitted about the same structure.
