Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a segment assembling apparatus for assembling a reinforcing segment for an inner wall surface of a tunnel.

[0002]

2. Description of the Related Art Conventionally, for example, when assembling a reinforcing segment to reinforce an inner wall surface of an existing railway tunnel, as shown in FIGS. A work truck 53 on which a reinforcing segment S and a crane device 52 for holding and moving the segment to a predetermined position on the inner wall surface of the tunnel T are placed so as to be able to travel, and a crane on the work truck 53 The assembling work has been performed by holding the reinforcing segment S by the device 52 and guiding the movement to a predetermined mounting position.

When the reinforcing segment S is moved and guided to a predetermined mounting position on the inner wall surface of the tunnel by the crane device 52, the reinforcing segment S is first moved to the crane device 52.
Member 52 provided at the tip of holding arm 52a
By holding the holding arm 52a on the b side and then performing the extension / contraction operation of the holding arm 52a and the turning operation of the turning member 52b, the movement to the predetermined position has been performed.

[0004]

By the way, in the above configuration, when positioning the reinforcing segment S, the holding arm 52a is operated in the tunnel axial direction t, so that the circumferential direction of the tunnel T is changed. In addition to the position control, the control in the extension and contraction direction of the holding arm 52a, that is, the control in the tunnel axis direction t also needs to be performed. Therefore, the control in the tunnel axis direction t is performed in the tunnel axis direction t. It is a difficult task to perform with the crane device 52 arranged in. In particular, it is very difficult to perform a positioning operation in a tunnel axial direction in a place where the operation width is narrow, such as in a tunnel.

[0005] Moreover, as the crane device 52,
Since a general-purpose machine for civil engineering work is used, it does not have a special mechanism for controlling the position and posture of the reinforcing segment S in the tunnel, and therefore has a narrow working space with a small working width. Therefore, there is a problem that it takes time to position the segments. Accordingly, an object of the present invention is to provide a reinforcing segment assembling apparatus capable of easily and quickly positioning a reinforcing segment.

[0006]

In order to solve the above-mentioned problems, a reinforcing segment assembling apparatus according to the present invention comprises a lifting member provided on a support base so as to be able to move up and down, and a first horizontal member attached to the lifting member. A moving body movably provided along the axial direction, a oscillating body supported movably in a vertical plane perpendicular to the first axial direction with the moving body, It comprises a retractable member provided so as to be able to move back and forth along a second axis direction orthogonal to the pivot axis, and a segment holder provided at a distal end portion of the retractable member.

Further, another reinforcing segment assembling apparatus of the present invention includes an elevating body guided up and down on a support table, an elevating cylinder apparatus for elevating the elevating body, and A moving body guided movably along the first axis direction, a moving cylinder device for moving the moving body in the first axis direction, and a direction perpendicular to the moving body in the first axis direction. An oscillating body supported to be swingable in a vertical plane, a first oscillating cylinder device for oscillating the oscillating body in a vertical plane, and a second axis orthogonal to the oscillating axis of the oscillating body. A retractable member provided so as to be retractable along the center direction,
A retractable cylinder device for retracting the retractable member in the direction of the second axis, and a tip end of the retractable member, which is swingably held around a third axis parallel to the first axis. The swing member includes a swing member, a second swing cylinder device that swings the swing member around the third axis, and a segment holder attached to the swing member.

Further, in each of the above reinforcing segment assembling apparatuses, the order of mounting the elevating body and the moving body is reversed. By arranging the segment assembling apparatus in each of the above configurations on a work carriage in the tunnel and the first axis is parallel to the tunnel axis, the segment for reinforcement is held and the cross section in the cross section of the tunnel is maintained. Since the mechanism that can move freely, that is, at least the retracting member and the swinging member, is provided on the moving body side that is freely movable along the tunnel axis direction, only by controlling this moving body, the reinforcing segment Positioning in the tunnel axis direction can be performed, and therefore, the positioning operation of the segments can be performed easily and quickly.

The support base 12 on the work vehicle 4 is provided at a position near the center of the tunnel T, and the swing center of the swing body 24 is
It is considered to be located near the center of the tunnel T. In addition, the segment holder 35 is provided with an engaging portion that is detachable from the engaged portion formed on the reinforcing segment S.

Therefore, in the above configuration, by operating the moving cylinder device 19, the moving body 18 is moved.
That is, the reinforcing segment S held on the moving body 18 side is moved in the first axial direction a, that is, the tunnel axial direction t.
To control its position. On the other hand, on the moving body 18 side, a segment holder 35 is sequentially provided via an oscillating body 24, a rod member 26, an oscillating member 29, and a revolving member 32, and each of these members is a first oscillating cylinder device. 25, the cylinder device 27 for retracting, the cylinder device 30 for the second swing, the cylinder device 33 for the swing, the cylinder device 36 for the third swing, and the like, in the tunnel cross section at the segment mounting position,
The reinforcing segment S can be freely moved.

That is, only one control shaft for moving the reinforcing segment S in the direction of the axis of the tunnel is required.
Numerous control axes for moving and guiding the reinforcing segment S along the circumferential direction of the inner wall surface of the tunnel exist in the cross section of the tunnel. Next, an operation of assembling a reinforcing segment on an inner wall surface of an existing railway tunnel, for example, by the segment assembling apparatus will be described.

[0015] As shown in FIG.
The work cart 4 on which the reinforcing segments S are mounted is moved to a position where the inner wall surface of the tunnel should be reinforced, and the segment holder 35 holds the reinforcing segments S. Next, the lifting body 15 is raised to an appropriate height by the lifting cylinder device 16,
The moving body 18 is moved by the moving cylinder device 19 to the segment mounting center position in the front-rear direction corresponding to the inner wall surface to be reinforced. The first axial direction a of the moving body 18
, The reinforcing segment S can be easily and quickly guided to the segment mounting position in the first axial direction a, that is, the tunnel axial direction t within the narrow tunnel T.

Next, as shown in FIG. 10, the lifting body 15 is raised to an appropriate height in an obliquely upward direction by the lifting cylinder device 16. Next, as shown in FIG. 11, the rocking body 24 is rocked upward by the first rocking cylinder device 25, and the rocking member 29 is rocked by the second rocking cylinder device 30 to provide reinforcement. The center of the segment S is set to a position corresponding to the mounting center position in the circumferential direction of the inner wall surface of the tunnel.

Next, as shown in FIG. 12, the turning member 32 is turned 90 degrees by the turning cylinder device 33 to bring the reinforcing segment S into a posture along the inner wall surface of the tunnel T. The rod 27 is projected by the device 27, and the reinforcing segment S is moved to the mounting position on the inner wall surface of the tunnel as indicated by the imaginary line. In addition,
At this time, if the posture of the reinforcing segment S does not match the inner wall surface of the tunnel, the third swing cylinder device 36
Is appropriately operated to make the posture of the reinforcing segment S coincide with the inner wall surface of the tunnel.

Then, when the reinforcing segment S is moved to its mounting position, the reinforcing segment S may be fixed to the inner wall surface of the existing tunnel T by a fixing member, for example, a connecting bolt. By repeating this procedure, the reinforcing segment S can be attached to the entire inner wall surface of the existing tunnel T. In this manner, the entire mechanism capable of holding the reinforcing segment and freely moving the segment in the cross section of the tunnel, that is, the rocking body, the rod member, the rocking member, and the turning member is moved along the tunnel axis direction. Since the movable segment is provided on the movable body, the reinforcing segment can be accurately moved and guided to the mounting position in the axial direction of the tunnel only by controlling the movable body.

That is, conventionally, it has been difficult to position the reinforcing segment in the axial direction of the tunnel. On the other hand, in the configuration of the segment assembling apparatus according to the present embodiment, the positioning of the reinforcing segment is performed easily and quickly. It can be carried out. To be more precise, as shown in the conventional example, when positioning the reinforcing segment, the segment assembly according to the present embodiment is more complicated than the case where the control in the extension and contraction direction of the holding arm parallel to the tunnel axis is required. In the device, after positioning in the axial direction of the tunnel, it is only necessary to control the posture in the cross section of the tunnel, and thus the control operation for positioning can be performed easily and quickly.

Further, as described above, the entire mechanism capable of holding the reinforcing segment and freely moving in the cross section of the tunnel is provided on a movable body movable along the tunnel axis direction. That is, since the lifting shaft, the swinging shaft, the telescopic shaft, and the turning shaft are arranged in a vertical plane perpendicular to the tunnel axis, the entire device can be made compact and the segment can be loaded on the work cart. Can be increased, and the operating range of each of the operating shafts is reduced. Therefore, the length of each member, for example, an arm member (consisting of a rod member, a turning member, a rocking member, etc.) on the tip side from the rocking body. Can be shortened, so that the mechanical rigidity is increased and the swing is reduced.

Further, as described above, since each operation axis is arranged in a vertical plane perpendicular to the tunnel axis, even if there is an obstacle such as a pillar at an intermediate position in the tunnel, it is easy to cope with it. can do. In addition, since the elevating shaft is inclined, the segment can be positioned on the inner wall surface of the tunnel with a small amount of movement of each operation axis.

Further, according to the above configuration, since the support base is disposed near the center of the tunnel on the work vehicle and the swing center of the swing body having the rod member is considered to approach the tunnel axis, the rod is The extension line of the extension / retraction axis of the member passes near the tunnel axis, so that the segment can be easily assembled. In addition,
In the description of the assembling work in the above embodiment, it is described that the moving body is first moved, then the elevating body is moved up and down, and the rocking body, the rod member, the rocking member, and the turning member are operated in this order. Of course, this order can be appropriately changed according to the working state at that time.

Further, in the above-described embodiment, the lifting guide rods are arranged at both ends of the support table. However, for example, the support table itself is constituted by two divided supports and The support may have a configuration in which elevating guide rods are provided. further,
In the above-described embodiment, the elevating body is supported on the support table so as to be able to move up and down, and the moving body is provided on the elevating body so as to be movable along the first axial direction which is the horizontal direction. Conversely, the moving body is placed on the support base in the first horizontal direction.
In addition to being supported so as to be movable along the axial direction, an elevating body may be provided on this moving body so as to be able to move up and down in the height direction, that is, in an oblique direction.

In this case, on the support base side, for example, a horizontal guide member in a horizontal direction is provided as a pair of upper and lower members, and a moving body guided by the two horizontal guide members is provided. One or two elevating guide members are provided, and an elevating body is provided on the elevating guide member so as to be able to elevate and lower. Of course, an oscillating body is attached to this elevating body.

[0025]

As described above, by arranging the segment assembling apparatus in each configuration of the present invention on the work vehicle in the tunnel and so that the first axis is parallel to the tunnel axis, the reinforcing segment is provided. And a mechanism that can move freely within the cross section of the tunnel, that is, at least the retracting member and the swinging member are provided at least on the movable body side that is movable along the tunnel axis direction, Accordingly, the positioning of the reinforcing segment in the axial direction of the tunnel can be performed simply by controlling the moving body, so that the positioning operation of the segment can be performed easily and quickly.

That is, as in the prior art, when using a crane device arranged along the tunnel axis direction to attach a reinforcing segment, the tilting operation of the holding arm in the crane device causes the telescopic operation. On the other hand, in the configuration of the segment assembling apparatus according to the present invention, the positioning in the tunnel axial direction only needs to control the moving body, and therefore, the segment positioning operation can be easily performed. And can be done quickly.
