Description

  The present invention relates to a tube material support method and a tube material support device for supporting a tube material.

  Pipes such as steel pipes are transported at the work site or from the storage location to the work site by hanging the crane hook using a hanging bracket or sling wire, or hanging using a lifting magnet. Generally, a method of laying rails and using a cart is used.

  As inventions of the method for transporting pipe materials, there are those disclosed in JP-A-8-239189, JP-A-11-294100, etc., all of which ensure safety and improve transport efficiency for large heavy objects and mass transport, It is intended to improve device durability, and requires a large crane or rail device.

JP-A-8-239189 Japanese Patent Laid-Open No. 11-294100

  Such a transport device does not consider the convenience in processing the pipe material. Therefore, it cannot process in the state hung on the crane or loaded on the carriage, and it is necessary to perform a setup different from the transportation method. That is, after transporting to a predetermined position by a method such as a crane, it is inefficient because it is necessary to cancel the slinging on the pipe material used for transport and install it on a jig for processing. .

  Here, the processing of the pipe material includes, for example, that it is necessary to process the pipe material used as a support in the pre-assembly process in the production of guard rails laid on the road. However, the present invention is not limited to this, and there are many scenes where the pipe material is processed.

  In order to perform the necessary movement of the pipe material or change of direction accompanying the processing, which is seen in such a scene, a plurality of setups such as attachment / detachment of the support device and installation to the spacer are required in advance. Moreover, since such a pipe material is generally heavy, consideration for safety is indispensable.

  However, as described above, a method and a device for transporting long and large-diameter pipe materials have been developed on the premise of mass transportation, but general-purpose that can handle various situations such as handling with a small turn when transporting or processing tube materials. There is no typical pipe operation method or transport device, and the work efficiency is greatly affected by the experience and skill level of the worker, and even the skilled worker cannot be said to have good work efficiency.

  In view of the situation as described above, the present invention provides a pipe support method and a pipe support apparatus that can easily and safely move a pipe and reduce the number of setups even when the pipe is processed. is there.

  In view of the above-described problems, the invention according to claim 1 is configured such that the rotating body provided on the outer periphery of the tube guide inserted into the support shaft is rotated along the inner wall of the tube, thereby allowing the tube guide to pass through. A tube material support method comprising: an insertion step of inserting the support shaft into one end of the tube material; and a support step of cantilevering the tube material by the tube material guide with the rotating body as a fulcrum.

  The rotating body provided on the outer periphery of the tube material guide refers to a rotating body as a bearing made of a roller or a ball. The pipe material here refers to, for example, a support fence (guard rail) post laid on the road, a road support post such as a reflector post installed on the road, and has a polygonal cross section, round shape, oval shape, etc. The same shall apply hereinafter.

  After the supporting step, a moving step for moving the tube while being cantilevered may be provided.

  The invention according to claim 2 includes a support shaft that is slidable in the axial direction, and a tube material guide that is fitted into the support shaft, and the tube material guide is provided on an outer periphery of the tube material guide. And a holding member that rotatably supports and supports the rotating body, and the tube material is inserted through the support shaft through the tube material guide, and the rotating body rotates along the inner wall of the tube material. Thus, the tubular material support device is cantilevered so as to be slidable in the axial direction of the tubular material.

  Specifically, the support shaft provided slidably in the axial direction means that the support shaft is slidably held in the A direction as shown in FIG. Taking the coordinate axis as shown in FIG. 1 results in a linear motion in the y direction. Accordingly, the tube material guide is slidable in the axial direction on the inner wall of the tube material.

  The holding member includes a front member and a rear member that are inserted perpendicularly to the support shaft, and a plurality of sets of connecting members that are provided orthogonally between the front member and the rear member. It is preferable that there is a rotating body that is rotatably supported by the connecting member. One or a plurality of rotating bodies may be used.

  If at least one of the support shaft and the tube material guide is rotatable in the circumferential direction of the tube material, the supported tube material can be rotated in the circumferential direction, which is suitable for this apparatus. Specifically, it means the rotation of at least one of the support shaft and the tube material guide in the B direction as shown in FIG. If the coordinate axis is taken as shown in FIG. 1, the rotation is about the y-axis. Along with this, the tube material is rotatable in the circumferential direction. There are mainly two modes, a mode in which the support shaft and the tube material guide rotate integrally, and a mode in which the support shaft and the tube material guide slide relative to each other. May be pivotable.

  By fitting a holder, which is a member for holding the support shaft, so as to be rotatable coaxially with the support column, the tube material can be rotated in the horizontal direction, which is suitable for this apparatus. Specifically, the ability to roll in the horizontal direction refers to a circular arc motion in the horizontal direction of the support shaft 4 with the column 6 in the D direction as a rotation axis, as shown in FIG. If the coordinate axes are taken as shown in FIG. 3, arc movement in the xy plane is obtained.

  The holder is provided with a sliding cylinder that is a member that directly holds the support shaft in a slidable manner, and the pipe is oscillated in the vertical direction by pivotally supporting the sliding cylinder in the vertical direction. If it has the characteristic of being free, the movement of a more general-purpose pipe material will be attained, and it is suitable for this apparatus. Specifically, the freely swingable in the vertical direction is a circular motion of the support shaft 4 in the vertical direction with the coupling point 53 in the C direction as the rotation axis as shown in FIG. If the coordinate axes are taken as shown in FIG. 2, arc movement in the yz plane is obtained.

  Further, if the holder is provided with a sliding stopper that reduces the diameter by lever operation and tightens the support shaft, the sliding stopper can arbitrarily regulate the sliding of the support shaft, which is suitable for this apparatus. .

  The invention according to claim 3 includes a support shaft provided slidably in the axial direction, and a tube material guide fitted into the support shaft, and the tube material guide is a rotating body provided on an outer periphery of the tube material guide. And a holding member that rotatably supports and supports the rotating body, and at least one of the support shaft and the tube material guide is rotatable in a circumferential direction of the support shaft. Is inserted into the support shaft through the tube material guide and is cantilevered so as to be slidable in the axial direction of the tube material by rotating the rotating body along the inner wall of the tube material. It is a pipe material support device.

  Specifically, the support shaft provided slidably in the axial direction means that the support shaft is slidably held in the F direction as shown in FIG. If the coordinate axes are taken as shown in FIG. 6, a linear motion in the y direction is obtained. Accordingly, the tube material guide is slidable in the axial direction on the inner wall of the tube material.

  The holding member includes a front member and a rear member that are inserted perpendicularly to the support shaft, and a plurality of sets of connecting members that are provided orthogonally between the front member and the rear member. It is preferable to provide a rotating body rotatably supported between them. One or a plurality of rotating bodies may be used.

  Specifically, at least one of the support shaft and the tube guide is rotatable in the circumferential direction of the tube. Specifically, as shown in FIG. 6, at least one of the support shaft and the tube guide in the G direction. One of the rotations. This is a rotation around the y-axis in FIG. As a result, the tube material is freely rotatable. There are mainly two modes, a mode in which the support shaft and the tube material guide rotate integrally, and a mode in which the support shaft and the tube material guide slide relative to each other. May be pivotable.

  It is preferable for the present apparatus to provide a leg portion having wheels as a base of the support column as a moving means. Specifically, the wheel as the moving means is a wheel for traveling on the rail as shown in FIG. 8. However, the wheel is not limited to traveling on the rail, but can be rotated by a caster, a swivel caster, a conveyor belt, or the like. Refers to the means of transportation using the body.

  The support shaft is preferably provided so as to be rotatable in the horizontal direction with the support column as a rotation axis. Specifically, as shown in FIG. 6, the pipe material is pivotally supported so as to be freely rotatable in the I direction. This is a rotation on the xy plane in FIG.

  It is preferable to provide a support column that supports the support shaft so as to be movable up and down. As a result, the supported pipe material can be raised and lowered while maintaining this supported state. Specifically, as shown in FIG. 6, the pipe material is supported so as to be movable up and down in the H direction. This is a linear motion in the z-axis direction in FIG.

  By supporting the support shaft with a universal bearing, the axial direction of the support shaft can be freely moved in an appropriate range in all directions with the universal bearing as a fulcrum. This is because the direction of the support shaft can be adjusted by this movement, and the insertion of the support shaft into the tube material can be facilitated.

  Specifically, this free-moving range is exemplified by a tube guide that is freely movable in a range of a substantially conical bottom circle having a vertex at the center of the universal bearing as indicated by a two-dot chain line in FIG. The inclination of the side surface from the perpendicular line from the apex of the substantially cone to the substantially center of the bottom circle is an appropriate angle for facilitating the insertion of the tube material guide into the tube material.

  Furthermore, it is suitable for this apparatus that the cam apparatus is brought into contact with the support bar by operating a lever so that the tilt angle of the support bar can be adjusted. Thereby, the elevation angle can be maintained in the cantilever support of the tube material, and the tube material can be prevented from coming off. In particular, it is effective when the universal bearing is provided as described above and the inclination angle of the support shaft can be adjusted.

  According to the present invention, the pipe material can be easily cantilevered, and can be rotated in the circumferential direction or in the axial direction while supporting the pipe material. The tube material here does not ask | require square shape or column shape.

  The cantilever can be easily supported by inserting and removing the tube, allowing the tube to be processed with the moved cantilever supported, and the tube material can be used universally and easily without interfering with sling wires and lifting magnets that were required in the past. Movement or processing becomes possible.

  Furthermore, by enabling the rotation in the circumferential direction and the rotation in the axial direction, the movement for various processing of the pipe material becomes very easy. In shifting from the movement of these pipe materials to the processing stage, not only the cantilever support state is maintained, but also the support shaft may be removed from the pipe material. In other words, the work process can be shortened by general-purpose movement of the pipe according to the situation. By shortening these work processes and reducing the burden on the workers, it becomes possible to carry out work that had to be done by a plurality of people in the past.

  The pipe material support devices 1 and 101 will be described as examples of the embodiment of the present invention. The drawings are all examples of the present invention, and the details described below do not limit the contents of the present invention described in the claims. Further, the configurations described below include those not essential to the present invention.

  Hereinafter, the pipe material support apparatus 1 of Example 1 of this invention is demonstrated with reference to FIGS.

  As shown in FIG. 1, the pipe material support device 1 supports a pipe material guide 3 inserted into a pipe material 2 to be handled, a horizontal support shaft 4 that supports the pipe material guide 3, a holder 5 that holds the support shaft 4, and a holder 5. Vertical struts 6 and leg portions 7 formed at the bases of the struts 6.

  The tube material guide 3 is inserted directly into the tube material 2 to support it. The tube material guide 3 is a holding member composed of a plurality of members, that is, a front plate 31 extending in a direction orthogonal to the direction A (the longitudinal direction of the support shaft 4, that is, the axial direction) in FIG. A rear plate 32 provided at intervals in the direction, a side plate 33 that connects the front plate 31 and the rear plate 32, and a roller 34 that is supported by the side plate 33 and whose axis is orthogonal to the axial direction of the support shaft 4. Yes. The side plate 33 is provided perpendicular to the front plate 31 and the rear plate 32. The front plate 31 and the rear plate 32 are plate members having a hole inserted through the support shaft 4. A side plate 33 and a roller 34 are provided between the front plate 31 and the rear plate 32. Two sets of side plates 33 are used, and four sets are used here. Two rollers 34 are rotatably supported between the pair of side plates. The tube material guide 3 is fixed to the support shaft 4 by bolting the tip of the support shaft 4 with the front plate 31 interposed therebetween. As shown in the B direction of FIG. 1 (rotation around the axial direction of the support shaft 4), the support shaft 4 and the tube material guide 3 rotate together. If the coordinate axis is taken as shown in FIG. 1, the rotation is about the y-axis. As a result, the tube 2 is rotatable in the circumferential direction.

  The support shaft 4 is inserted through the tube material 2 via the tube material guide 3 and supports it. The support shaft 4 is slidably held in the A direction of FIG. The sliding of the support shaft 4 can be regulated by a sliding stopper 52 provided on the holder 5. The sliding stopper 52 is made of an annular member, and the lever 52a provided on the sliding stopper 52 is rotated to reduce the inner diameter of the annular member, thereby operating the tightening of the support shaft 4.

  Further, a stopper 41 is provided at the opposite end of the support shaft 4 from the pipe guide 3. The retaining member 41 balances the function of preventing the supporting shaft 4 from coming off from the holder 5, the function as a gripping part for manually performing the pivoting operation of the supporting shaft 4 or the tube material 2, and the weight of the tube material 2. It can also have a role such as a function as a weight for the purpose.

  The holder 5 includes a horizontally arranged sliding cylinder 51, a sliding stopper 52 that restricts the sliding of the support shaft 4, a hinge 53 that pivotally supports the sliding cylinder 51, and a base portion 54 that supports the holder 5. The support shaft 4 is attached to the support column 6. The holder 5 is fitted to the column 6 at the base 54 so as to be rotatable coaxially therewith (rotation in the D direction of FIG. 3, xy plane). Further, the sliding cylinder 51 is pivotally supported by the hinge 53 so as to freely rotate (direction C in FIG. 2, rotation in the yz plane). As a result, the tube material 2 can be turned in the axial direction horizontally or vertically.

  The sliding cylinder 51 holds the support shaft 4 so as to be slidable, but at the same time, enables rotation of the support shaft 4 in the circumferential direction (direction B in FIG. 1). Therefore, the pivotability of the tube guide 3 fixed to the tip of the support shaft 4 is also ensured. Here, the inside of the sliding cylinder 51 is constituted by an oil-free bush. Depending on the weight of the pipe material 2 to be handled, a ball bearing may be used as a countermeasure for seizure.

  The support 6 supports the holder 5 or the tube material 2. The lower end is fixed to the base 71 of the leg portion 7, and the base portion 54 of the holder 5 is inserted into the upper end.

  The leg portion 7 includes a pedestal 71 that fixes the column 6, a leg frame 72 that supports the pedestal 71, and a fixture 73 that fixes the leg frame.

  The tube material support device 1 is characterized by cantilever support of the tube material 2 and has a large moment load by the tube material 2. Therefore, when the pipe material 2 has a considerable weight, the weight of the retaining member 41 that fixes the leg portion 7 to the rail 80 or makes the pedestal 71 has a substantial weight as shown in the use example of FIG. It is necessary to take measures such as adjusting the

  The clearance between the inner surface of the tube material 2 and the outer surface of the tube material guide 3 may be appropriately adjusted depending on the inner diameter, material, weight, material of the roller 34, and the like. The clearance is approximately 0% to 3% of the inner diameter of the tube material 2, and is approximately 0.2% to 1.5% for easy handling and safety.

  In the embodiment of the present invention, it is called a “cantilever support state” for convenience, but strictly speaking, when counted along the axial direction of the tube material 2, there are a plurality of rollers 34 (two in each group here), Since the tube material 2 is inclined by a small angle (Θ in FIG. 4) due to its own weight, the tube material 2 is supported substantially at two points (points a and b in FIG. 4) as shown in FIG. 4B. Therefore, the tube material 2 inserted through the tube material guide 3 is stably supported by its own weight (W in FIG. 4). If the clearance between the inner surface of the tube material 2 and the outer surface of the tube guide 3 is appropriate, this support becomes a more reliable cantilever support state.

  Below, the usage method of the pipe material support apparatus 1 is demonstrated. The pipe material support device 1 is fixed to the rail 80 with the fixture 73 of the leg 7 as shown in FIG. If the fixing tool 73 is loosened, the rail 80 can be moved in the E direction (longitudinal direction). First, the support shaft 4 is inserted through the tube material 2 via the tube material guide 3 so that the tube material 2 is in a cantilevered state. In this state, the tube material 2 can move such as circumferential rotation (direction B in FIG. 1), axial horizontal rotation (direction D in FIG. 3), and vertical rotation (direction C in FIG. 2). Further, parallel movement in the axial direction (direction A in FIG. 1) is also possible by the sliding cylinder 51, and parallel movement in the axial direction can be arbitrarily restricted by the sliding stopper 52.

  If the pipe 2 is prepared at a desired position by making full use of the above movement, the machining operation can be performed while rotating the pipe 2 in the circumferential direction. In addition, the horizontal turning, the vertical turning, and the translation can be performed while the pipe member 2 is cantilevered. In FIG. 5, a square member rotating device 81 is installed on the rail 80 on which the tube material supporting device 1 is installed, so that the processing device 82 can perform processing while applying a rotational force to the tube material 2. The tube material 2, the tube material guide 3, and the support shaft 4 rotate coaxially. For example, a heat-resistant shrinkable tube can be welded to the surface of the tube material 2 by a heating device, and used for manufacturing a buried underground strut.

  In the first embodiment, a square pipe is handled as the pipe material 2, but it is of course possible to handle a round pipe or the like.

  The tube material guide 3 can be easily replaced as an attachment. In the first embodiment, there are four side plates 33, which can be used for a square pipe. The side plate 33 may have three sets for moving the round pipe. Generally, the pipe material has a bead portion that is a seam by welding, and it is desirable to avoid external force to this portion as much as possible. However, it is easy to avoid the bead portion of the round pipe by using three side plates 33. Because. In this respect, since the corner pipe is supported at four corners, the bead portion can be avoided.

  The material used for the roller 34 of the tube guide 3 can be made of metal, but a material having both rigidity and elasticity such as hard plastic and synthetic rubber is preferable. Moreover, if the projection which becomes the stopper of the pipe material 2 is provided in the rear plate 32, or the rear plate 32 is made larger than the diameter of the pipe material 2, the pipe material 2 will not be inserted into a position closer to the support column 6 any more. It is possible to guide at a predetermined insertion position.

  The support shaft 4 is rotatable in the circumferential direction, and the tube material guide 3 is not freely rotatable with respect to the support shaft 4 in the front plate 31 and the rear plate 32, but such a configuration may be adopted. Is possible. In this case, it is not necessary to ensure the pivotability of the support shaft 4 with respect to the holder 5.

  In addition, the pivotability of the tube guide 3 and the support shaft 4 is passively enabled, but an active mechanism for rotating the tube guide 3 and the support shaft 4 itself is provided, thereby rotating the tube material 2 in the circumferential direction. A moving operation can also be made possible.

  The effect of the pipe material support apparatus 1 according to the first embodiment will be described. If this pipe material support device 1 is used, the setup such as lifting by a wire or the like can be eliminated or reduced, and the pipe material 2 can be adjusted to a desired position by rotation, rotation, and horizontal movement in the axial direction. The tube 2 can be processed while the tube 2 is cantilevered. Further, even when processing is performed while rotating the circumferential direction of the tube material 2, it is possible to perform the processing stably without the rotation axis of the tube material 2 being shaken. As described above, since the number of setup steps can be reduced and the pipe material 2 can be stabilized, the work that can be done by one person even if the work of two or more people has been required in the past increases.

  Hereinafter, the pipe material support apparatus 101 of Example 2 of this invention is demonstrated with reference to FIGS. About a structure which is common with the pipe material support apparatus 1, a part number is made into 100 series, description is used and a difference is mainly demonstrated. As shown in FIG. 6, the tube material support device 101 includes tube material guides 103 a and 103 b that are inserted into the tube material 202 (see FIG. 8), a support shaft 104 that supports the tube material guides 103 a and 103 b, a holder 105 that holds the support shaft 104, A column 106, a leg 107, and a hoist attachment member 108 are provided.

  The tube material guides 103 a and 103 b are the same as the tube material guide 3 in the tube material support device 1. The reason why a plurality of pipe guides 103a and 103b are provided is to make it possible to easily adjust the insertion length of the pipe 202 in consideration of the purpose of movement. Therefore, the tube material guide 103b is slidable on the support shaft 104. As for the tube material guide 103b, one set of rollers is provided for each set of side plates.

  The support shaft 104 is inserted through the tube material 202 via the tube material guides 103a and 103b and supports the tube material guide 103a and 103b. The support shaft 104 is slidably held by a bearing unit 510 attached to the holder 105 so as to be freely movable in about 5 ° in all directions.

  As shown in FIG. 7, “movable in about 5 ° in all directions” means that the distal end of the tube material guide 103 a can be moved in a substantially bottom circle range in a substantially cone of a indicated by a two-dot chain line. This substantially cone has an angle between a perpendicular line from the vertex to the center of the bottom circle and the side surface in a range of about 5 ° from the vertex. This angle is not limited to 5 °, and may be set as appropriate. Further, a stopper 141 is provided at one end of the support shaft 104.

  Further, a horizontal level adjustment unit 520 is provided in the holder 105 on the side opposite to the bearing unit 510.

  The horizontal level adjustment unit 520 rotates the control lever 522 that is eccentrically attached to the center of the circle of the control roller 521, thereby pressing and controlling the control roller 521 that moves up and down from above the support shaft 104, and thereby adjusting the angle of the pipe material 202. It is an eccentric cam that adjusts to a predetermined position within the playable range. The horizontal level adjusting unit 520 may be configured so that the pipe material guides 103a and 103b can be adjusted to the horizontal or the upward inclination angle at which the pipe material guides 103a and 103b are lifted forward.

  Next, referring mainly to FIG. 7, the holder 105 includes a bearing unit 510, a horizontal level adjustment unit 520, an elevating unit 530, a turning cylinder 540, and an operation lever 550.

  The elevating unit 530 is an assembly of members that are slidable in the vertical direction with the support column 106 as an axis, and includes an upper plate 531, a lower plate 532, a moving roller 533, a rolling bearing roller 534, and a resin thrust load. It comprises a receiving portion 535 and a lifting hook 536.

  A movement roller 533 is attached to the upper plate 531 so as to be movable in the vertical direction around the support column 106. An elevating hook 536 for attaching the hook 109a (see FIG. 8) of the hoist 109 is also attached thereto.

  The upper plate 531 and the lower plate 532 are ring-shaped plates, and these are connected by using the rotating shaft of the rolling bearing roller 534.

  On the upper surface of the lower plate 532, a thrust load receiving portion 535 formed in the same ring shape is provided. Here, the thrust load from the rotating cylinder 540 is received by sliding contact. However, when the apparatus is large, a ball bearing for thrust load may be used instead of resin.

  The rolling cylinder 540 is formed in a substantially cylindrical shape, and is provided between the upper plate 531 and the lower plate 532 so as to be rotatable about the support column 106 by a rolling bearing roller 534. The bearing unit 510, the horizontal level adjustment unit 520, and the operation lever 550 are provided in the turning cylinder 540.

  The operation lever 550 is a round pipe that selects any one of the brackets 560 that are fixed in four directions in the rolling cylinder 540 and is inserted into the hole of the bracket 560.

  The support column 106 supports the holder 105 or the pipe material 202. The lower end of the column 106 is fixed to the pedestal 710 of the leg 107, and the hoist mounting member 108 is attached to the upper end of the column 106 (see FIG. 6). As long as it does not interfere with the leg 107 or the hoist attachment member 108, the holder 105 slides around the support 106 along the shaft 106 (direction H in FIG. 6).

  The leg 107 includes a pedestal 710 and a leg frame 720, and a movement roller 721 is built in the leg frame 720.

  Below, the usage method of the pipe material support apparatus 101 is demonstrated. As shown in FIG. 8, the pipe material support device 101 is installed on a rail 900 so as to be slidable (direction J in FIG. 8) with a roller 721 for moving a leg.

  A commercially available hoist 109 is attached to the hoist attachment member 108, and the hanging hook of the hoist 109 is hooked on the lifting hook 536.

  Similar to the tube material support device 1, the tube material 202 is inserted into the tube material guide 103 to be in a cantilever support state.

  In this state, the pipe 202 is moved in parallel with the rail 900 in the horizontal direction (direction J in FIG. 8) by the movement of the operation lever 550, vertically moved by the hoist 109 or the lifting unit 530 (direction H in FIG. 6), the operation lever. Rotation movement (direction I in FIG. 6) in the rotation section 540 by operation 550 (here, manual but may be automatic), circumferential rotation by the support shaft 104 or the bearing unit 510 (G direction in FIG. 6) Is possible.

  Further, the support shaft 104 and the tube material 202 have a floating region (region A in FIG. 7) of approximately 5 ° in a conical shape with the bearing unit 510 as a fulcrum. This is because the tube material guides 103a and 103b can be easily inserted into the tube material 202 in consideration of the case where the tube material 202 is long.

  Along with the provision of this free range, a horizontal level adjustment unit 520 is provided. The pipe material 202 is caused to flow by the inclination of a minute angle of the pipe material 202 in the clearance between the inner surface of the pipe material 202 and the outer surface of the pipe material guide 103 (see Θ in FIG. 4B) or downward force due to the bending of the pipe material 202 itself. Since the guide 103 may come off unexpectedly, the horizontal level adjusting unit 520 maintains a slight elevation angle and reliably supports the pipe material 202.

  In addition to the above, the tube support device 101 according to the second embodiment uses two of the tube guide 103a and the tube guide 103b for more stable support of the tube 202 in consideration of the purpose of movement. . As a result, the amount of insertion into the pipe material 202 can be adjusted, and a more stable and stable support state can be achieved.

  By the above operation, the tube material 202 in the cantilevered support state is moved or can be processed in the supported state. In FIG. 8, a pipe material rotating device 910 is installed on a rail 900 on which the pipe material supporting device 101 is installed, and processing is performed by the processing device 920 while applying a rotational force to the pipe material 202. The tube material 202, the tube material guides 103a and 103b, and the support shaft 104 rotate coaxially. The tube rotating device 910 has the same structure as the tube rotating device 81 shown in FIG. 5, and the processing device 920 has the same structure as the processing device 82 shown in FIG.

  In addition, the basic points are the same as those of the pipe support device 1 of the first embodiment, such that the pipe guides 103a and 103b can be easily replaced as attachments.

  This pipe material support device 101 is intended for simple movement of the pipe material and is suitable for short-distance to medium-distance movement, and is basically unsuitable for long-distance / mass transportation, but it can also increase movement efficiency by several methods. it can.

  As shown in FIG. 8, moving efficiency can be increased by installing a plurality of pipe material support devices 101 on the track of a set of rails 900.

  By providing a plurality of support shafts 104 or tube guides 103a and 103b in one tube support device 101, the amount of movement at a time can be increased. Further, the amount of movement of the tube material can be increased by making the tube material 202 into 3 bundles of 3 × 3 and supporting one tube material among them.

  The rail 900 necessary for the pipe material support device 101 is sufficient as compared with other rail devices for mass transportation. Furthermore, if the weight of the pipe material 202 to be handled is small or the weight of the leg 107 is sufficiently large, the pipe material support device 101 can be used more generally without being installed on the rail 900.

  Due to the above characteristics, the pipe material support device 101 according to the second embodiment can be optimally used at a work site where the pipe material needs to be moved or processed, for example, found in a construction site.

  The effect of the tube material support apparatus 101 according to the second embodiment will be described. If the tube material support apparatus 101 is used, it is possible to eliminate or reduce setup such as lifting with a wire or the like, and to move the tube material 202 more easily than in the past. Depending on the size, weight, etc. of the tube material 202, it is possible to perform work alone, which conventionally requires two or more workers. The tube material can be processed in the moving state, and the number of work steps can be reduced.

  INDUSTRIAL APPLICABILITY The present invention can be used in operations that require the movement of pipes or the movement of pipes for processing. The pipe material to be handled is not limited to a steel pipe, and the present invention can be used as long as it has a considerable degree of rigidity such as reinforced plastic.
