[0006]

Embodiments of the present invention will be described below with reference to the drawings. In the following description, a case of a road tunnel will be described, but the present invention is also applicable to a case of a railway tunnel.

<A> Overall Configuration FIG. 1 is a side view of a ceiling panel replacement apparatus 1 according to the present invention, and FIG. 2 is a sectional view thereof. The ceiling panel re-seat device 1 includes a work truck 2 formed in a gate shape, and a traveling device (monorail) 3 installed in the same direction as the movement of the work truck 2 on the left or right side top of the work truck 2 in a gate shape. And a lifting device (chain block) 4 suspended at each of the front and rear ends of the monorail 3, and a vertically movable table lift 5 installed below each chain block 4.

<B> Work Cart The work cart 2 is a horizontally movable gantry formed in a gate shape in the moving direction. In the present embodiment, the work vehicle 2 secures the effective width W of the vehicle passing through the tunnel, forms a gate shape straddling the road in a straddling manner, and forms the protruding portion 6 outside the top of the work vehicle 2. In this case, the monorail 3 and the chain block 4 are suspended, but the entire cross-section inside the tunnel may be formed as a work carriage 2 having an effective width W and formed in a gate shape. Here, the effective width W refers to a road width that allows a car passing in a face-to-face manner or a car passing in one way to pass without contact. The work cart 2
The vehicle is equipped with a generator 7, a motor 8 for running, and running tires 9 so that it can move on a road. A protruding portion 6 is formed at the top of the work vehicle 2 outside the effective width W, and a monorail 3 and a chain block 4 described below are suspended and installed. An outrigger 10 is provided at the lower part of the work cart 2 so as to maintain stability during lifting work. Stairs 11 are provided at predetermined locations on the work cart 2 to facilitate movement of workers.

<C> Monorail and Chain Block The monorail 3 and the chain block 4 are known jigs for lowering the aging removed ceiling panel A and raising the newly installed ceiling panel B. The monorail 3 is fixed in a direction orthogonal to the projecting portion 6 of the work cart 2. The length of the monorail 3 is set to protrude from the front and rear of the work vehicle 2, and the chain block 4 is suspended on the front and rear protrusions, respectively. Therefore, it is possible to easily carry in and out the removal ceiling panel A and the newly installed ceiling panel B.

<D> Table Lift A table lift 5 that can be moved up and down is installed directly below the monorail 3. The table lift 5 is a removable ceiling panel A
And a device for performing a lifting operation of the newly installed ceiling panel B. The lifting operation of the table lift 5 employs conventionally known means. The table lift 5 is divided and installed at two places in the front and rear direction of movement of the work vehicle 2, and the table lift 5 in the forward direction (arrow) is dedicated to removal and removal of the ceiling panel A,
The rear table lift 5 is used for exclusive use for carrying in and installing the newly installed ceiling panel B.

[0011]

The operation of the present invention will be described below.

<A> Installation of the Work Cart The front end of the work cart 2 is moved to the position of the obsolete removed ceiling panel A. After the movement is completed, the outrigger 10 provided on the work vehicle 2 is pressed against the road surface by a known method, thereby ensuring stability when a load is applied to the work vehicle 2. In the present embodiment, the outriggers 10 are installed on only one side of the work cart 2 (FIG. 2), but may be installed on both sides if necessary.

<B> Removal of Ceiling Panel Using the flat surface at the top of the work vehicle 2 as a scaffold, the aging removed ceiling panel A is removed by any method such as human power or a machine. The removal ceiling panel A lifts and mounts the table lift 5 in the forward direction (arrow) of the work vehicle 2, then lowers the table lift 5, loads the truck on a truck or the like, and carries it out of the tunnel.

<C> Loading and Installation of Ceiling Panel In parallel with the work of removing the ceiling panel, the work of loading and installing a new ceiling panel B is performed. The newly installed ceiling panel B carried into the site lowers the table lift 5 behind the work vehicle 2, and transfers the newly installed ceiling panel B from the truck to the lower table lift. After the transfer work is completed, the table lift 5 is raised to the top of the work cart 2, and the work of installing the new ceiling panel B is performed. In the installation work of the new ceiling panel B, the panel lifting cylinder 12 installed outside the pillar of the work cart 2 is operated, and is placed and fixed on a panel support 13 previously attached to both side walls above the tunnel.

[0015]

Since the present invention has been described above,
The following effects can be obtained. <A> The work vehicle has a gate-shaped structure that secures the effective width of vehicles passing through the tunnel and straddles the road in an overpass, so that traffic is not temporarily interrupted during construction. You do not have to bother passing vehicles. <B> For the same reason, efficient work can be performed without night work, and the problem that the construction period and construction cost increase can be solved. <C> Since the monorail is formed so as to protrude from the front and rear of the work cart, it is possible to easily carry out the removed ceiling panel and carry in the newly installed ceiling panel. <D> Since the table lift is structured to move up and down just below the monorail, it is possible to easily carry in / out the ceiling panel. <E> Since the table lift is divided into two parts at the front and rear of the work cart, the loading, unloading, removal and installation of the ceiling panel can be performed simultaneously in parallel, which can be an efficient work.
