Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for transferring a segment mounted on a segment carriage traveling on a rail to another segment carriage, and a segment transfer method.
[0002]
[Prior art]
In small and medium-sized cross-section shields, the traveling track of the segment truck can usually be installed only by a single line. Therefore, although short-distance construction is good, when long-distance construction is performed, as shown in FIG.
[0003]
[Problems to be solved by the invention]
The above prior art has the following problems.
<I> The excavation work must be stopped for a few days in order to create a breakout line.
<B> Since the pedestrian passage c is interrupted at the evacuation line, an accident may occur at this portion.
<C> In addition, it is necessary to provide safety equipment such as a signal and a circuit breaker at a portion where the pedestrian passage c is interrupted.
<D> Furthermore, since the passage c for pedestrians is interrupted, depending on the situation, the supervisor and the worker are stopped, resulting in a loss of time.
<E> Since the carriages can only be exchanged at the part of the evacuation line, one of the carriages waits first, which may be inefficient.
<F> There may be cases where a small-diameter can not be used to install a retractable line.
<G> The location of the shelter line is preferably between the vertical shaft and the face, but once the shelter line is installed, the position is fixed, so the shield extends and the distance from the face becomes longer. Inefficiency.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the transfer device 100 of the present invention will be described with reference to FIGS.
<A> Guide frame The guide frame 110 is formed in a gate shape with two column portions having a square cross section and a beam portion connecting the upper ends thereof. This guide frame 110 is erected at two positions on the iron plate 111 at a predetermined interval.
[0006]
<B> The iron plate 111 is slidably installed on the segment cart travel rail 200 installed in the tunnel, and the entire transfer device 100 can be moved on the rail 200. To do. The iron plate 111 is formed wider than between the rails 200, and the outriggers 112 are provided at the four corners to ensure stability. The iron plate 111 is installed so that the upper guide frame 110 straddles the rail 200. A space surrounded by the guide frame 110 and the iron plate 111 is defined as a transfer area 113 for storing the segment cart 300.
[0007]
<C> Riding Rail As shown in FIG. 1, the riding rail 114 is installed on the upper surface of the iron plate 111 so as to be positioned directly above the rail 200, and as shown in FIG. The upper surface of 111 to the upper surface of the rail 200 are continuously formed in a slope shape. Accordingly, the segment cart 300 can be made to enter the transfer area 113 via the ride-up rail 114.
[0008]
<D> The elevating frame elevating frame 120 is a gate-shaped frame arranged inside each guide frame 110. The guide frame 110 and the elevating frame 120 are double gates inside and outside. A shape frame is formed. The support rods of the two front and rear lifting frames 120 are connected by a horizontal transmission beam 121. Further, the support beams 115 in the horizontal direction are also connected between the support pillars of the two front and rear guide frames 110.
[0009]
The transmission beam 121 and the support beam 115 are connected by a lift jack 130 in the vertical direction. Further, the elevating frame 120 is equipped with a guide roller 122, and the guide roller 122 can be raised and lowered along the guide frame 110. Therefore, when the lift jack 130 is expanded and contracted, the lifting frame 120 can be lifted and lowered along the guide frame 110.
[0010]
<E> Change Arms Change Arms 140 are in the shape of an inverted shape as shown in FIG. 1 and their bent portions are pivotally supported by connecting members 123 provided at both ends of the transmission beam 121. It is. A support member 141 projects from the lower end portion toward the inside, and the upper end portion is connected to the holding jack 142. Accordingly, when the change jack 142 is extended and contracted, the change arm 140 opens and closes in a direction substantially orthogonal to the rail 200 with the shaft support portion as a fulcrum.
[0011]
[Transfer method]
Next, a segment moving method will be described with reference to FIG. First, the segment transfer device 100 configured as described above is installed in the middle of the rail 200. The installation location is preferably an intermediate point between the shaft and the face, and the iron plate 111 is slid on the rail 200 and moved to a predetermined position.
[0012]
The segment 400 is mounted on the segment carriage 300 a on the shaft side, travels on the rail 200, and is stored in the transfer area 113 of the transfer device 100 via the ride-on rail 114. Refer to FIG.
[0013]
Here, the changeover jack 142 is extended to close the changeover arm 140, and the support member 141 is inserted from both sides of the lower portion of the segment 400 to support the lower surface of the segment 400. Next, the lift jack 130 is extended, and the segment 400 is lifted through the lifting frame 120 and the holding arm 140. Refer to FIG.
[0014]
After the segment 400 is lifted, the segment carriage 300a is moved out and returned from the area 113, and the segment 400 is loaded again on the shaft side. On the other hand, from the face side, an empty segment cart 300b is transferred and stored in the transfer area 113, and the segment 400 suspended thereon is mounted. Then, the segment 400 is transferred to the work place on the face side, and one cycle is completed. See (c) and (d) of FIG.
[0015]
【The invention's effect】
Since the present invention has been described above, the following effects can be obtained.
<I> Since there is no need to make a breakout line, it is not necessary to stop the excavation work.
<B> Since the pedestrian passage is not interrupted at the evacuation line, safety can be improved. Also, there is no need to provide safety equipment such as signals and circuit breakers. In addition, supervisors and workers will not be suspended.
<C> Since the transfer device is movable, it can be installed at the most efficient place such as an intermediate position between the shaft and the face, and the carriage can be operated efficiently.
<D> Since the track is straight, it can also be applied to small-diameter tunnels.
<E> There is no need to provide a special mechanism for the carriage, and a normal simple carriage can be used.
