Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for moving scaffolding temporarily installed for inspection and repair of plate gutter, truss, etc. on the inner surface of a bridge or viaduct.

(Prior art) Temporary scaffolding used for such purposes has traditionally been suspended scaffolding, which is assembled by suspending pipe materials or wood from plate girders, etc. with chains, but temporary construction work generally requires high It is a labor intensive process, requires a great deal of effort, is expensive, and is inefficient. Furthermore, since the suspended scaffolding was fixed, it was impossible to move it to adjacent sections.

On the other hand, in order to solve these problems, a dedicated scaffolding having a self-propelling function as shown in FIG. 9 has been proposed. This is the flange plate 7 of the plate gutter 2 on the inner surface of the road floor plate 1.
A traveling roller 4 is placed on top of the scaffold 3, and the scaffold 3 is suspended by the roller 4, and is driven by a rotary drive motor 5 in the direction of the bridge axis.

However, in such a device, since the running roller 4 rolls on the flange plate 7 of the plate gutter 2, it damages the painted surface. Also, flange plate 7
There were problems such as difficulty in getting over stiffeners, connecting bolts, and other obstacles that existed in the system.

(Problems to be Solved by the Invention) The present invention attempts to solve problems in conventional scaffold moving devices, such as damage to painted surfaces and difficulty in climbing over obstacles.

Therefore, the present invention aims to provide three or more sets of upper and lower clamp devices that sandwich substantially horizontal flange plates and can be opened and closed, a movable table equipped with the clamp devices, and a movable table. This device is equipped with a feeding device that can individually slide or roll in the direction of movement, a chuck device that attaches and detaches the moving platform to the feeding device, and a scaffold equipped with a rail that guides the moving platform. It is intended as a means to solve the problem.

(Function) When each upper and lower clamp device and chuck device are turned on and the feed device is operated, only the scaffolding can be moved. Furthermore, when a set of upper and lower clamp devices is opened and only the chuck device is turned on, the movable table can be moved along the rail together with the clamp device.

(Embodiment) An embodiment of the present invention will be described below with reference to Figs. 1 and 2. Fig. 1 shows the moving device of the present invention attached to the plate gutter 2 on the lower surface of the road floor plate in the cross-sectional direction of the bridge axis. Figure 2 shows the installation state in the longitudinal direction of the bridge axis. Further, details of section A in FIG. 1 and section B in FIG. 2 are shown in FIGS. 3 to 7, respectively. This mobile device is mainly composed of a modular mobile unit (general name of part A) and a scaffold 3 equipped with handrails 6, etc., and has a new feature in the movement pattern of the mobile unit.

Now, in FIGS. 3 to 7, an L-shaped rail 9 is attached to the upper surface of a flange 8 which is appropriately connected to the scaffold 3 in the direction in which the scaffold is moved. Furthermore, a motor 1 is mounted on the end surface of the rail 9.
2, and a horizontal threaded rod 11 rotatably attached along the same-shaped rail 9 can be rotationally driven. Each horizontal threaded rod 11 has 3
A set of movable tables 14 are fitted, and each movable table 14 is attached with a running roller 10 inserted into the I-shaped rail 9. In addition, 13 is the moving table 1 to the horizontal screw keyaki 11.
It is a chuck device that engages 4, and can be attached to or detached from the screw thread.

A guide vibe 15 is vertically provided on the traveling base 14,
Furthermore, two sets of vertical threaded rods 16 are installed, and the vertical threaded rod 16 has an upper clamp plate 18 and a support plate 19 built into it on one side, and a lower clamp plate 17 that constitutes a lower clamp device on the other side. A motor 20 is connected to the upper part of 16. The upper clamp device is composed of an upper clamp plate 18 and a support plate 19. As shown in FIG. 6, a guide vibe 15 and a vertical screw rod 16 are inserted into the support plate 19, and the upper clamp plate is It is fitted into the support plate 19 and can be rotated by 90 degrees.

The guide vibe 15 and the vertical screw keyaki 16 have their upper ends attached to the plate 2.
A motor 20 for rotation of the vertical threaded rod 16 is mounted on the plate 22 . Also, the support plate 19 of the upper clamp device and the vertical threaded rod 1 of the lower clamp plate 17
The insertion part 6 is threaded. Reference numeral 23 is a removable bottle for stopping the relative rotation of the upper clamp plate 18 and support plate 19 of the 11-ni clamp device.

Next, to explain the operation, when installing the inspection/repair scaffolding 3 to the plate gutter 2, first tighten the upper clamp plate 18 by 90"
In the rotated state (position W where the upper clamp plate 18 faces downward in Fig. 6), lift the entire device from below to a position where the flange plate 7 of the plate gutter 2 can be held, and then move the upper clamp plate 18 to the flange. After rotating to a position where the plate 7 is sandwiched, the motor 20 is driven, and the upper clamp plate 18 and the lower clamp plate 17 are lowered and raised, respectively, to sandwich the flange plate 7.

The motor 20 collectively represents the motors 20a and 20b, and the motor 20a connects the upper clamp plate 18 and the motor 2
0b can raise and lower the lowered clamp plate 17 individually by the feeding action of the screw. Figures 1 and 2 show how they are installed. In the figure, all the clamping devices clamp the flange plate 7, and in this state it is possible to inspect and repair members such as bridges on the scaffolding 3. .

Next, to explain the procedure for moving this scaffold, Figure 8 shows the procedure, and (A) shows the state before moving, with the scaffold 3 under the plate gutter 2, and the plate gutter It is suspended by three sets of clamp devices. In addition,
The triangular ( ) symbol in the figure indicates that the clamp plates 17 and 18 and the chuck device 13 are turned ON (engaged). F1
~F3 indicates three sets of moving platforms.

Now, from the state of (a), the movement of cycle (1) is performed in the steps of (b) to (to). That is, in (b) F2 and F3
After turning on only the clamp plates 17 and 18 of Fl and supporting the scaffold 3 with F2 and F3, only the chuck device 13 of Fl is turned on.
N and rotate the motor 12. As a result, the moving platform F1
The chisel moves to position (c).

Next, in the state (c), clamp plates 17.
18 and chuck device 13 are all turned on and the motor 12
When rotated, the scaffold 3 moves horizontally to the position (d). Next, in the state (d), the clamp plates 17 of Fl and F3
．． Only 18 is turned on, and only the chuck device 13 of F2 is turned on.
After setting it to N, rotate the motor 12 to change F2 to (
Move to position e). Next, from the state (e), Fl
After turning on only the clamp plates 17 and 18 of F2 and turning on only the chuck device W13 of F3, the motor 12 is rotated to move F3 to the (to) state. Then, one cycle of movement is completed at (to).

(Effects of the Invention) As explained in detail above, the present invention is configured so that the flange plate of the plate gutter is less likely to be damaged by the movement of the scaffolding according to the movement pattern, and the plate gutter can be easily overcome by stiffeners, gashefts, etc. Furthermore, stable movement with rigid support by the clamp device can be realized.
