Description

  The present invention relates to an erector device that is disposed in a cylindrical shield frame in a shield machine and used when a segment is assembled to a wall surface of a drilled hole.

  In recent years, various developments have been made with respect to an erector apparatus used in a shield machine, and as the segment split angle increases or the girder thickness (thickness) of the segment increases, the segment of the cylindrical shield frame in the shield machine is increased. Development of an erector apparatus that can move in a high stroke in two stages in the radial direction is also in progress (see Patent Document 1). The configuration of the erector apparatus according to this prior art will be described as follows.

  In other words, a ring-shaped swivel frame is provided at the rear of the shield frame so as to be pivotable about the axis of the shield frame. In the shield frame, a plurality of revolving frame motors that revolve the revolving frame are disposed at intervals in the circumferential direction (the circumferential direction of the shield frame).

  A pair of first support arms projecting rearward is provided on one side portion of the swivel frame so as to face the radial direction of the swivel frame, and a pair of first support arms projecting rearward is provided on the other side portion of the swivel frame. The second support arm is provided opposite to the radial direction. In addition, a guide rod extending in the radial direction is provided between the pair of first support arms and between the pair of second support arms, respectively.

  On the outer peripheral surface of each guide rod, a slide frame is provided so as to be movable in the radial direction (outer radial direction / inner radial direction), and each slide frame is provided on the front side of the guide rod, Each has a front through hole. In addition, a slide frame jack for moving the slide frame in the radial direction with respect to the guide rod is provided at the rear of each slide frame.

  On the inner peripheral surface of the front through hole of each slide frame, a slide rod extending in the radial direction is fitted and provided so as to be movable in the radial direction. Further, an arcuate detent frame is provided between one slide frame and the other slide frame, and this detent frame is made of high-rigidity H-shaped steel.

  A suspension beam is connected between the tip of one slide rod and the tip of the other slide rod. In addition, a suspension beam jack that moves the suspension beam integrally with the slide rod in the radial direction with respect to the slide frame is provided at the front portion of each slide frame.

  The suspension beam is provided with a sliding frame that can move in the front-rear direction. The sliding frame has a gripping portion that grips a gripped portion of the segment. Further, a sliding frame jack for moving the sliding frame in the front-rear direction with respect to the suspension beam is provided at the center of the sliding frame.

  Therefore, first, the swivel frame is swung integrally with the sliding frame by driving a plurality of swivel frame motors in a state in which the gripped portion of the appropriate segment is gripped by the gripping portion. Thereby, a suitable segment can be made to oppose the segment assembly location of the wall surface of a hole.

  Next, the slide frame jack is driven to move the pair of slide frames in the outer radial direction (the radial direction approaching the wall surface of the hole) with respect to the guide rod, and the suspension beam jack is driven to drive the suspension beam. The slide rod is moved integrally with the slide rod in the outer radial direction. Thereby, an appropriate segment can be divided into two steps and moved in the outer radial direction with a high stroke to be positioned at the segment assembly location on the wall surface of the hole. Here, since a rigid locking frame is provided between one slide frame and the other slide frame, the slide frame is sufficiently restricted from rotating around the axis of the guide rod. The appropriate segment can be accurately positioned at the segment assembly location on the wall surface of the hole.

  When positioning a suitable segment, the swivel frame is slightly swung integrally with the sliding frame by driving a plurality of swivel frame motors, so that the proper segment is circumferentially (circumferential direction of the shield frame). The position may be adjusted, or the position of an appropriate segment may be adjusted in the front-rear direction by slightly moving the slide frame in the front-rear direction by driving the slide frame jack.

And an appropriate segment is integrally joined to an existing segment with a bolt or the like. Thereby, an appropriate segment can be assembled | attached to the segment assembly location of the wall surface of a hole.

  By the way, in order to accurately position and assemble the segment at the segment assembly position on the wall surface of the hole, as described above, the slide frame should not be rotated around the axis of the guide rod by the rigid rotation frame. Need to be fully regulated. On the other hand, if the detent frame is included as an essential component of the elector device, the weight acting on the slide frame increases, and the slide frame jack increases in size, making it impossible to make the elector device compact.

  In other words, in the erector device according to the prior art, the segment is accurately assembled to the segment assembly location on the wall surface of the hole while suppressing the increase in size of the slide frame jack and reducing the size of the erector device. Has the problem of being extremely difficult.

  Then, an object of this invention is to provide the erector apparatus of a novel structure which can solve the above-mentioned problem.

Therefore, the appropriate segment can be accurately positioned at the segment assembly location on the wall surface of the hole.

  When positioning the appropriate segment, the revolving frame is slightly rotated integrally with the sliding frame to adjust the position of the appropriate segment in the circumferential direction (the circumferential direction of the shield frame). The position of the appropriate segment may be adjusted in the front-rear direction by moving the slide frame slightly in the front-rear direction.

  And the said appropriate segment is integrally joined to the said existing segment with a volt | bolt etc. Thereby, the said appropriate segment can be assembled | attached to the segment assembly location of the wall surface of the said hole.

  As described above, according to the present invention, the slide frame can be sufficiently restricted not to rotate around the axis of the guide rod without using a highly rigid rotation stop frame. The weight of the slide frame can be reduced, the size of the slide frame jack that moves the slide frame in the radial direction with respect to the guide rod is suppressed, and the segment of the segment is reduced while reducing the size of the erector device. It can be accurately assembled to the segment assembly location on the wall surface of the hole.
