Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile turntable for reversing the direction of a small vehicle that travels on a rail (track) laid in a mine and carries people and materials during shield work or the like. .

[0002]

2. Description of the Related Art In a shield construction method or a propulsion construction method for constructing a sewer pipe or a common ditch underground, when excavating soil is transported to the outside, a track is laid inside the excavation pit and the excavated earth and sand is converted into a steel car on the track. It is loaded and the steel car is towed by a battery car and taken out of the mine. On the other hand, when the shield construction has a small diameter, workers and construction supervisors make a round trip from the lower part of the manhole continuing to the mine to the face by a passage beside the track laid in the mine. In a small-diameter mine, for example, when the finished diameter is small and 1350 mm, the user walks with his or her waist bent along a passage provided beside the rail.

As another passage means, a passenger truck apparatus disclosed in Japanese Patent Application No. 3-287452 of the present applicant is known. This passenger trolley device is to be excavated by a shield machine, and a rail on which a support truck behind the shield machine travels and a rail on which a carrier truck for carrying out sand and sand travels are laid, and further below the rail on which the carrier truck travels. Auxiliary rails are laid in the groove part of the vehicle, and a drive carriage equipped with a battery is arranged on the auxiliary rails, and a passenger carriage is arranged on the rail on which the transport carriage travels. And
Allowing workers and construction supervisors to ride on a passenger truck that is detachably connected to a drive truck on an auxiliary rail and travels,
Only the dolly is arranged on the rail on which the transport dolly travels, and the dolly is driven by human power.

[0004]

In the construction work of sewer pipes and common grooves in the shield construction method, workers and supervising personnel frequently pass at the tip of the excavation. In particular, the supervising staff frequently go back and forth to instruct and confirm the excavation and check the tip of the excavation. In such a case, when the pipe diameter of the mine is 1750 mm or more, it is possible to walk in the mine in a substantially normal posture, but at the pipe diameter (1150 to 1650 mm) of a small cross section, the mine space is narrow, so work is required. The staff members and superintendents either walk with their necks bent or walk in the middle waist, so they have to walk a long distance of 1-2 km with a bad posture in a long mine, and it is physically painful due to poor posture. I was forced to. In addition, since the supervising staff frequently travels back and forth during excavation, it may take a lot of time, which may interfere with other construction supervision, and the staff may have to be increased. I am in difficulty.

For this reason, a small underground electric vehicle capable of carrying one supervising staff member or worker is created so that the electric vehicle can be run on a rail on which a carrier truck or the like travels, so that the supervising staff member or the like can quickly move in the underground well. I have a suggestion to do. However, after moving from the vertical shaft side through the mine to the excavation tip position with the underground electric car,
Alternatively, after moving toward the vertical shaft, the direction of the underground electric car must be reversed when turning back, and in that case, the underground electric car must be reversed manually, which is a difficult work. The present invention is proposed in view of the above problems, and an object thereof is to turn back after a small electric vehicle moves when the small electric vehicle moves back and forth on a rail laid in a mine. Therefore, the present invention provides a mobile turntable in which a small electric vehicle can be easily inverted inside a mine.

[0006]

SUMMARY OF THE INVENTION The present invention achieves the above object in a turntable for reversing the direction of a small vehicle traveling on a rail laid in a mine. A guide member for guiding along the underground rail is provided on the lower surface of the rectangular substrate installed on the underground rail, and a central axis is provided at the center of the upper surface of the substrate. A rotating plate is arranged in the center of the substrate and its center hole is fitted to the central axis, and a large number of spheres are provided between the center portion of the substrate and the rotating plate and between a plurality of concentric guide rings. And a rail corresponding to the underground rail is provided on the upper surface of the rotary plate. Further, on both sides of the rotary plate on the base plate, inclined roads having rails corresponding to the underground rails are provided. In addition, the movable turntable has a central shaft provided at the center of the upper surface of the substrate, a rotating plate is disposed on the substrate, and a central hole of the rotating plate is fitted to the central shaft so that the central portion on the substrate and the rotating plate are A plurality of casters are attached at appropriate intervals to either one of the lower surface of the rotating plate, a rail corresponding to the underground rail is provided on the upper surface of the rotating plate, and rails corresponding to the underground rail are provided on both sides of the rotating plate on the substrate. It is possible to adopt a configuration in which an inclined road having the above is provided. Further, in order to fix the rotary plate at the front-rear position before and after the reversal, a stopper means is provided between the rotary plate and the substrate so that a small vehicle can be stably placed on and off the turntable. Further, a bottom plate having substantially the same size as the rotating plate is provided in the central portion of the substrate, and the rotating device from the bottom plate to the rotating plate is integrally formed and detachable from the substrate.

[0007]

The movable turntable described above is installed at the excavation tip position inside the mine or near the bottom of the shaft. Then, in the electric vehicle traveling on the laid rail, the rails on the inclined roads on both sides of the rotary plate of the turntable and the rails laid inside the mine are guided in the same track, and reach the rail provided on the rotary plate. After that, the stopper means of the rotating plate is released, the direction is reversed, and it can pass through the inclined road again and return to the underground rail, so change the direction by the turntable installed near the excavation tip or vertical shaft and move. You can Further, when the turntable is moved, the guide member at the lower part of the substrate can be guided on a rail laid in the mine, and the turntable can be pulled and moved by a battery car or the like. Furthermore, since the turntable has inclined roads with rails on both sides of the rotating plate, even if it encounters a steel car that conveys sand, it can pass through the rails of the inclined road and the rails of the rotating plate. , There is no obstacle to the running of other vehicles.
Further, since the rotating device from the bottom plate to the rotary plate is configured to be detachable from the substrate, the work of inserting the turntable into the mine or out of the mine is facilitated by the removal.
