Description

  The present invention relates to an apparatus for constructing a band-shaped member bundle in which long band-shaped members wound spirally to form a spiral tube are wound in a hollow cylindrical shape.

  In an existing pipe that has deteriorated, a belt-shaped member is wound spirally to form a spiral pipe, and lining is performed using the spiral pipe that has been manufactured. In such an existing pipe lining method, since the belt-shaped member is fed directly into the existing pipe, it is necessary to transport the long belt-shaped member to the construction site.

The belt-shaped member is usually transported to the site while being wound around a transport drum. The transport drum around which the belt-shaped member is wound is configured by integrating a pair of disk-shaped side plates by connecting a plurality of connecting rods, and inserting and connecting a cylindrical body at the center thereof. In addition, a long belt-like member is wound around the body, and after a certain length of the belt-like member is wound, the body is pulled out from the side plate in a state where the belt-like member is wound. Then, the transport drum on which the belt-like member is wound is transported to the construction site and temporarily placed, and the belt-like member is pulled out from the inner peripheral side of the transport drum and fed into the existing pipe, and spirally formed in the existing pipe. By being wound, spiral tubes are sequentially manufactured (see, for example, Patent Document 1).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  First, prior to describing the apparatus for constructing the band-shaped member bundle according to the present invention, the band-shaped member bundle 1 will be described with reference to FIG.

  The band-shaped member bundle 1 is manufactured using a manufacturing drum 10 described later, and is formed into a hollow cylindrical shape by winding a band-shaped member 1A of a helical tube that lines an existing pipe that has deteriorated. Thereafter, the binding band 2 is spaced apart in the circumferential direction through a cushioning material 4 such as cardboard on the outer peripheral surface, inner peripheral surface, and left and right side surfaces of the hollow cylindrical strip-shaped member 1 ′ (in the embodiment, 90 ° in the embodiment). The film 3 is wound and bundled at four intervals with an interval of the degree, and a plurality of films 3 are laminated on the outer peripheral surface thereof.

  As a result, the band-shaped member bundle 1 is fixed at a plurality of positions by the banding band 2 in a direction intersecting with the winding direction of the wound hollow cylindrical band-shaped member 1 ′, so that the band-shaped member 1A is unwound. It is possible to reliably prevent the ejection. In addition, since the belt-like member 1A is fixed by the plural layers of the film 3 in the winding direction, even if the binding by the binding band 2 is released when the belt-like member 1A is pulled out, the outer diameter direction depends on the rigidity of the belt-like member 1A. Can be prevented from expanding and expanding in diameter, and can be reliably held in a hollow cylindrical shape with the original outer diameter.

  When manufacturing such a strip | belt-shaped member binding body 1, the manufacturing drum 10 shown in FIG. 4 is used.

  The manufacturing drum 10 includes a pair of left and right side frames 11, 11 and a plurality of connecting rods 12 and tension rods 13 (see FIG. 5C) that can be detachably connected between the side frames 11, 11. , Is composed of.

  Each side frame 11 includes an inner peripheral ring 14, an outer peripheral ring 15, and a plurality of reinforcing bars 16 that are radially connected to each other between the inner peripheral ring 14 and the outer peripheral ring 15 in the circumferential direction. In addition, a slit 16a is formed along the longitudinal direction, and a stopper 17 is fixed close to the inner peripheral ring 14 to interrupt the slit 16a.

  The connecting rod 12 and the tension rod 13 are rod-like bodies having the same structure with nuts (not shown) fixed at both ends, and the connecting rod 12 and the tension rod are passed through the slits 16 a of the reinforcing bars 16 in the side frame 11. The connecting rod 12 and the tension rod 13 can be detachably connected to the side frame 11 by being screwed into the nut 13.

  In order to assemble the manufacturing drum 10 configured as described above, the bolts 18 are inserted through the slits 16a of the corresponding reinforcing bars 16 in the left and right side frames 11 and 11, and the connecting rods 12 disposed between the left and right side frames 11 are inserted. Screw into the nut and connect the connecting rod 12 to the left and right side frames 11. At this time, the bolt 18 is inserted into the slit 16 a so as to be positioned on the outer peripheral side of the stopper 17 to connect the connecting rod 12. Similarly, the connecting rods 12 are connected in order at intervals in the circumferential direction. Thereby, the left and right side frames 11, 11 are connected by the plurality of connecting rods 12, and the manufacturing drum 10 is assembled. At this time, a winding core is formed by a plurality of connecting rods 12 connected at intervals in the circumferential direction.

  Next, the manufacturing method of the strip | belt-shaped member binding body 1 using the manufacturing drum 10 is demonstrated based on FIG.

  The assembled production drum 10 is placed on a turntable 30 (see FIG. 5A) in which the left and right side frames 11 and 11 are rotatably supported by a pair of rotating rollers 31. . Thereby, the manufacturing drum 10 can be rotatably supported.

  On the other hand, although not shown in detail, the belt-like member 1A pushed out from the molding apparatus is wound around a winding drum, and the winding drum is rotatably supported at a position facing the manufacturing drum 10. . And after fixing the front-end | tip of the strip | belt-shaped member 1A wound up by the winding drum to the manufacturing drum 10, the manufacturing drum 10 is rotated, the strip | belt-shaped member 1A is pulled out from a winding drum, and strip | belt-shaped member 1A is made into several pieces. The connecting rod 12 is wound up as a winding core (see FIG. 5A). When the outer diameter set by sequentially winding the belt-shaped member 1A is reached, the rotation of the production drum 10 is stopped, and the left and right side surfaces, the outer peripheral surface, and the inner surface of the rolled hollow cylindrical belt-shaped member 1 ′ are stopped. The binding band 2 is wound around the peripheral surface, and is tightened and bound (see FIG. 5B).

  Here, the insertion of the binding band 2 is formed between the reinforcing bars 16 and 16, the space formed between the inner ring 14 and the stopper 17, and the outermost band member 1 </ b> A and the outer ring 15. This is done by using a space.

  When bundling with the bundling band 2, in order to prevent the band-shaped member 1A from being damaged, a cushioning material 4 such as cardboard is interposed between the left and right side surfaces, the outer peripheral surface, and the inner peripheral surface of the hollow cylindrical band-shaped member 1 ′. The binding band 2 is wound around the outside of the cushioning material 4.

  Similarly, the binding band 2 is wound in order through the buffer material 4 at intervals of 90 degrees and bound. Next, after cutting the belt-like member 1A, the film 3 is wound around the outer circumferential surface of the hollow cylindrical belt-like member 1 ′ bound by the binding band 2 at a plurality of positions at intervals in the circumferential direction so as to be covered (see FIG. 5 (c)).

  Thereby, the wound hollow cylindrical belt-like member 1 ′ is fixed by the plurality of binding bands 2 in a direction intersecting with the winding direction of the belt-like member 1A, and plural in the winding direction of the belt-like member 1A. The band-shaped member bundle 1 is manufactured by being fixed by the layer film 3.

  When the band-shaped member bundle 1 is manufactured, the tension rod 13 is disposed between the left and right side frames 11 and 11 on the outer peripheral surface of the band-shaped member bundle 1, and the slits 16 a of the corresponding reinforcing bars 16 are arranged. Bolts 18 are inserted through the nuts and screwed into the nuts of the tension rod 13 to connect the tension rod 13 to the left and right side frames 11. Similarly, tension rods 13 are connected to the left and right side frames 11 and 11 at a plurality of locations at intervals in the circumferential direction. Next, after the production drum 10 is rotated so that the plurality of tension rods 13 are positioned below, the bolts 18 fixing the connecting rod 12 are loosened to release the connection, and the connecting rod 12 is connected to the inner ring. Remove through 14. As a result, the band-shaped member bundle 1 is supported by the plurality of tension rods 13. Next, although not shown in detail, if the connection is released by loosening the bolt 18 that fixes the tension rod 13 while supporting the band-shaped member bundle 1 using an overhead crane or the like, the connection is made by the tension rod 13. The formed side frames 11 and 11 are detached and disassembled into a pair of side frames 11 and 11, a plurality of connecting rods 12 and tension rods 13 constituting the manufacturing drum 10 (see FIG. 5D). Then, after carrying out the strip | belt-shaped member binding body 1 to a storage place, in the storage place, the strip | belt-shaped member binding body 1 is laid down and stored so that the hollow part may face an up-down direction (refer FIG.5 (e)).

  For this reason, the band-shaped member bundle 1 is fixed in a direction in which the wound hollow cylindrical band-shaped member 1 ′ intersects the winding direction of the band-shaped member 1 </ b> A by a plurality of binding bands 2. Since the film 3 of the layer is fixed in the winding direction of the band-shaped member 1A and is stored in a state where the hollow portion is directed in the vertical direction, the unraveling of the band-shaped member 1A is surely prevented and inadvertently It can be stored stably without starting to move. Moreover, since the drum can be stored without using it, it is not necessary to secure a large space for storing the drum.

  Next, the construction apparatus 5 of the present invention that transports such a band-shaped member bundle 1 to the construction site, draws the band-shaped member 1A from the band-shaped member bundle 1 and supplies it to the existing pipe will be described.

  As shown in FIG. 1, the construction device 5 includes a rotary table 6 and a drive device 7 that rotationally drives the rotary table.

  Here, although not shown in detail, the rotary table 6 is a conventionally well-known one comprising a table main body 62 rotatably supported by a base 61 via a bearing, and the outer diameter of the band-shaped member bundle 1 is shown. It has a sufficiently large vertical and horizontal dimension.

  The drive device 7 is a variable speed motor capable of adjusting the rotation speed and the rotation direction. Although not shown in detail, a drive sprocket is provided on the output shaft of the drive device 7. A driven sprocket is provided, and a chain is wound between the driving sprocket and the driven sprocket so that the rotational drive of the driving device 7 is transmitted to the table main body 62 of the rotary table 6.

  In this case, belt pulley transmission or gear transmission can be used instead of chain sprocket transmission, and an electric motor or hydraulic / pneumatic motor can be used as the driving device.

  The drive device 7 includes an operation device 8 that adjusts the rotational speed and direction of the variable speed motor.

  Next, a construction procedure for drawing out the belt-like member 1A from the belt-like member bundle 1 using the construction device 5 configured as described above will be described with reference to FIG.

  At the construction site, a construction apparatus 5 is prepared in advance by a contractor.

  On the other hand, when the band-shaped member bundle 1 is transported to the construction site in a state of being laid down with the hollow portion facing up and down by a truck or the like, the band-shaped member bundle 1 is suspended by using a crane or the like. It is placed on the table main body 62 of the rotary table 6. Next, the binding band 2 of the band-shaped member binding body 1 is cut, and the fixation in the direction intersecting the winding direction of the band-shaped member 1A is released. However, the outer peripheral surface of the band-shaped member bundle 1 is covered with a plurality of layers of films 3, thereby preventing spreading in the outer diameter direction and continuously holding the original outer diameter. In this state, the winding start end portion of the band-shaped member 1A is pulled up from the inner peripheral side of the band-shaped member bundle 1 and pulled outward, and the band-shaped member 1A is guided into the existing pipe through the manhole M and mounted on a pipe making machine (not shown). To do. Thereafter, the band-shaped member 1A is sequentially drawn out from the inner peripheral side of the band-shaped member bundle 1 and supplied to the existing pipe, whereby the band-shaped member 1A is spirally wound in the existing pipe to form a helical tube.

  At this time, in the existing pipe, when the belt-like member 1A is spirally wound and the spiral pipe is manufactured, the belt-like member 1A drawn out from the belt-like member bundle 1 is also twisted in a spiral. The band-shaped member 1A accumulates the twist as the number of times it is spirally wound, and therefore the band-shaped member 1A may be plastically deformed and bent or broken due to the accumulated twist.

  For this reason, when pulling out the band-shaped member 1A from the inner peripheral side of the band-shaped member bundle 1, the operator operates the operating device 8 to adjust the rotation speed of the rotary table 6 in the clockwise direction or the counterclockwise direction. By rotating, the band-shaped member bundle 1 is rotated in conjunction with each other. Thereby, 1 A of strip | belt-shaped members pulled out from the inner peripheral side of the strip | belt-shaped member binding body 1 can be controlled to an appropriate twisted state. Therefore, compared with the case where the operator manually rotates the heavy transport drum to control it in an appropriate twisted state, the labor can be reduced and the work can be safely performed. Even if the twist remains in the member 1A, the twist can be easily eliminated.

  Further, by pulling the band-shaped member 1A upward from the inner peripheral side of the band-shaped member bundle 1 in which the hollow part is arranged in the vertical direction, the band-shaped member 1A is laterally moved from the inner peripheral side through the hollow part of the transport drum. Compared to the conventional example of pulling out, the belt-like member 1A does not jump up and down in the hollow portion of the transport drum, or jumps out to the opposite side to the pulling direction, has a stable posture, and does not get caught. The belt-like member 1A can be pulled out safely.

  By the way, in embodiment of the construction apparatus 5 mentioned above, although the case where the rotation speed and rotation direction of the turntable 6 were controlled remotely via the operation apparatus 8 was demonstrated, as shown in FIG. A pulling device 9 provided with a variable speed motor (not shown) capable of rotatably supporting a pair of rotating rollers 92, 92 on the support member 91 and adjusting the rotational speed of the pair of rotating rollers 92, 92 is provided. The construction device 5 may be arranged to arrange the belt-shaped member 1A automatically from the inner peripheral side of the belt-shaped member bundle 1.

  Here, the rotation rollers 92 and 92 of the drawer device 9 are set so that the distance between the rotation rollers 92 and 92 can sandwich the band-shaped member 1A, and the rotation direction is from the band-shaped member bundle 1 to the band-shaped member 1A via the variable speed motor. Is set to pull out.

  The drawer device 9 includes an operating device 8 that adjusts the rotational speed of the variable speed motor.

  Even when the band-shaped member 1A is pulled out from the band-shaped member bundle 1 using the construction device 5 configured as described above, the band-shaped member bundle 1 transported to the construction site is rotated in a laid down state with the hollow portion directed vertically. After mounting on the table main body 62 of the table 6, the binding band 2 of the strip-shaped member binding body 1 is cut, and the fixing in the direction intersecting the winding direction of the strip-shaped member 1A is released. Next, the winding start end portion of the band-shaped member 1A is pulled up from the inner peripheral side of the band-shaped member bundle 1 and pulled outward, and is inserted between the pair of rotating rollers 92, 92 of the drawer device 9, and then the band-shaped member 1A is It is guided through the manhole M into the existing pipe and mounted on a pipe making machine (not shown). Next, by operating the operation device 8 to rotate the pair of rotating rollers 92 and 92 of the drawer device 9, the belt-shaped member 1 </ b> A is sequentially pulled out from the inner peripheral side of the belt-shaped member bundle 1 and supplied to the existing pipe. In the existing pipe, it is wound in a spiral shape to produce a helical pipe. Here, the operator can operate the operating device 8 to adjust the rotation speed of the pair of rotating rollers 92, that is, the pull-out speed of the band-shaped member 1A. 1 A of strip | belt-shaped members can be automatically pulled out from the inner peripheral side.

  In order to prevent the twist of the band-shaped member 1A drawn from the band-shaped member bundle 1 from accumulating, the band-shaped member bundle 1 is rotated clockwise or counterclockwise via the rotary table 6, The belt-like member 1A drawn out from the inner peripheral side of the belt-like member bundle 1 is controlled to an appropriate twisted state.

  Thus, compared with the case where the operator manually pulls up the band-shaped member 1A from the inner peripheral side of the band-shaped member bundle 1, the labor of the operator can be greatly reduced and the drawer operation can be performed safely. It can be carried out.

  Further, the belt-shaped member 1A is pulled out upward from the inner peripheral side of the band-shaped member bundle 1 in which the hollow portion is arranged in the vertical direction, whereby the belt-shaped member 1A is laterally moved from the inner peripheral side through the hollow portion of the transport drum. Compared to the conventional example of pulling out, the belt-like member 1A does not jump up and down in the hollow portion of the transport drum, or jumps out to the opposite side to the pulling direction, has a stable posture, and does not get caught. The belt-like member 1A can be pulled out safely.
