DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving device for driving a transport device such as a hoist which moves a material such as a wall segment from a ceiling in a tunnel in a shield tunnel construction. In particular, the present invention relates to a magnet belt driven type in which an endless magnet belt is attracted to a laid hanger rail and rotated to obtain a propulsive force.

[0002]

2. Description of the Related Art Conventionally, a transporting apparatus for suspending and moving materials and equipment has a motor-driven gear at an upper part of a main body and can move along an I-shaped hanger rail with a rack installed for traversing. There is a hoist provided in. The hoist advances on the hanger rail by rotating while engaging a gear with a rack of the hanger rail.

[0003]

In recent years, the depth of shield tunnels has tended to increase, many sections have steep slopes, and a transport device for moving materials and equipment requires a large driving force. However, the hoist has a problem that the propulsion force is small, the climbing force is weak in a steep section, and it is difficult to follow the rail when passing through a laterally curved section.
Therefore, the present invention provides a magnet belt type for a hanging transfer device that can attract a magnet belt to a hanger rail and draw it around to obtain a large propulsion force, travel with excellent climbing performance, and smoothly pass through even a sharp bend section. It is an object to provide a driving device.

[0004]

In order to solve the above-mentioned problems, in the present invention, for example, a drive for driving a suspended conveyance device by adsorbing a magnet belt on a hanger rail 1 made of steel material and installed on a ceiling portion in a tunnel. In the device,
A pair of front and rear traveling wheels 7 are arranged and provided on the left and right sides in the extending direction of the hanger rail 1, and the traveling wheels 7 are rolled on the lower flange 1 a of the hanger rail 1 while adsorbing the magnet belt 14 on the lower surface of the lower flange 1 a. The magnet belt 14 is wrapped around the sprockets 12 and 13 so as to advance in the extending direction, and the magnet belt 14 is drawn around by the drive motor 15 so that the pair of front and rear guide rollers 8 are sandwiched on the hanger rail 1 in the extending direction left and right while contacting the side surfaces in the horizontal direction. A magnet belt type driving device for a hanging transport device is configured to be rolled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. 1 is a schematic front view of a driving device according to the present invention, FIG. 2 is a front view of the driving device, FIG.
FIG. 4 is a sectional view taken along line IV-IV. In FIG. 1, reference numeral 1 denotes a hanger rail made of a steel material having a substantially I-shaped cross section and laid on a ceiling in a tunnel. The hanger rail 1 has a hoist 2 which is a hanging transfer device movable along the hanger rail 1,
A self-propelled drive device 3 for driving this is mounted. The drive device 3 and the hoist 2 are connected by a connecting rod 4. The hoist 2 can lift and lower materials such as the wall segment S by using a wire rope with a hook, and can move along the hanger rail 1 in the tunnel.

[0006] As shown in FIGS.
Has a rectangular box-shaped frame 5 whose upper part is open. There is an interval between the side plates 5a, 5a of the frame 5 facing in parallel so that the hanger rail 1 can be received. A front plate 5b for connecting the side plates 5a, 5a of the frame 5 at a front portion is provided with a tab 5c for freely connecting the connecting rod 4. Inside the side plates 5a, 5a, a pair of front and rear traveling wheels 7, 7 which roll on the lower flange 1a of the hanger rail 1 in the extending direction thereof are provided. Further, inside the side plates 5a, 5a, a pair of front and rear lateral guide rollers 8, 8 which are rotatable in the horizontal direction in contact with the edge of the lower flange 1a are provided. Further, inside the side plates 5a, 5a, a pair of longitudinal guides are arranged so as to sandwich the lower flange 1a of the hanger rail 1 between the running wheels 7 and contact the lower surface of the lower flange 1a and roll in the extension direction. Rollers 9, 9 are mounted.

The front and rear portions of the side plates 5a, 5a are provided with shafts 10, 1 respectively.
1 is erected. The shafts 10, 11 are rotatably supported between the side plates 5a, 5a.
The driven sprocket 13 is fixed. A magnet belt 14 is looped between the sprockets 12 and 13. The magnet belt 14 is a lower flange 1 of the hanger rail 1.
A large number of magnet pieces 14a that can be attracted to the lower surface of a are provided. The drive motor 15 with a speed reducer is fixed outside one of the side plates 5. The shaft 10 is a drive motor 15
Output shaft. Therefore, the magnet belt 14 is routed by the motor 15. Power is supplied to the motor 15 through a cable (not shown). The driving operation is performed on the control panel 6.
This is performed by the switch 6b connected to a.

[0008] A chain guide 16 for stretching the magnet belt 14 is provided between the side plates 5 and 5. As shown in FIG. 5, the chain guide 16 is provided with support bolts 16 below a base plate 16a fixed between the side plates 5 and 5.
An arm 16d having a substantially H-shaped cross section is supported in the front-rear direction via b, and a sprocket 16e is rotatably supported at both ends of the arm. The support bolt 16b is a nut 16
c, the fixed position with respect to the base plate 16a can be changed up and down, and the sprocket 16
The position of e can be adjusted.

As shown in FIGS. 1 and 4, one side plate 5 is provided.
A limit switch 17 is protrudingly provided at the front and rear upper portions. Further, a striker 18 abutting on a limit switch 17 is fixed to a predetermined stop position of the hoist 2 on the hanger rail 1. Further, a stopper 19 for preventing passage of the hoist 2 and the driving device 3 is provided in the vicinity thereof.
Is provided.

Thus, the hoist 2 is provided with the wall segment S.
Such materials are suspended and driven by the drive device 3 to move the materials from the transport vehicle to the vicinity of the excavator, and then lower and temporarily load. The driving device 3 moves the magnet belt 14 to the hanger rail 1
The material is conveyed by strongly pulling or pushing the hoist 2 by magnetic friction while adsorbing the lower surface of the lower flange 1a. Even if the hanger rail 1 has a steep vertical gradient, the equipment is smoothly transported without slipping. In addition, it exerts enough climbing power even on uphill. Since the lateral guide rollers 8 and 8 roll by contacting the edge of the lower flange 1a, even if the hanger rail 1 bends in the horizontal direction, the hanger rail 1 smoothly advances along the hanger rail 1. Since there is no need to attach a rack or the like to the hanger rail 1 as in the related art, the installation is easy and the cost is not increased. The present invention is not limited to the hoist for transporting the materials and equipment in the tunnel construction as described above, but can be applied to various transport devices that suspend and move the transported object.

[0011]

As described above, in the present invention, the magnet belt 14 is attracted to the hanger rail 1 to drive the transfer device, so that the transfer device can be easily moved on a steep transfer path with a large propulsion force. There is an effect that no large-scale equipment is required, so that no large cost is required for installation, and that the vehicle can smoothly pass through a sharply curved section on the transport path.
