These elevating beam support members 11H are provided so as to extend below the two base beams 11 in the Y-axis direction (FIGS. 3 and 4), and are lifted by the elevating beam 12 (later member 42 described later) by a horizontal upper surface portion. The lifting beam 12) in an unsupported state is supported from below.

  The elevating beam 12 can be moved up and down in a region above the reference position (region between the two base beams 11) with a position supported from below by the plurality of elevating beam support members 11H as a “reference position”. it can. That is, the elevating beam 12 is configured to be movable up and down with respect to the base beam 11 in the present embodiment. 3, 4 and 5 show a state in which the elevating beam 12 is located at the reference position.

  2 and 3, end plates 19 are attached to both ends of the two base beams 11 in each support base 10 in the X-axis direction. A rod-like member 20 extending in the vertical direction can be detachably attached to each end plate 19.

  2, 3, and 6, an operation panel 21 is provided on one of the two end plates 19. The operation panel 21 is provided with two operation buttons 22 (an up button 23 and a down button 24). Here, an example in which the operation panel 21 is provided on the end plate 19 attached to the front of the support base 10 is shown, but the operation panel 21 may be provided on the end plate 19 attached to the rear of the support base 10. Good. Further, it may be provided on both the front and rear end plates 19.

  3 and 5, a pillow material 31 is provided on the upper surface of each of the two base beams 11. The pillow 31 is made of, for example, a resin material and has a cushioning property. The pillow 31 may be formed on the upper surface of the base beam 11 so as to extend in the longitudinal direction of the base beam 11, and may be composed of one member or a plurality of members.

  3, 4, 5, and 6, a plurality of rollers 32 are provided on the upper surface of the elevating beam 12 so as to be aligned in the longitudinal direction of the base beam 11. Each roller 32 is held by a roller holder 33 so as to have a rotation axis 32J (FIG. 4) in a horizontal direction (Y-axis direction) orthogonal to the longitudinal direction (X-axis direction) of the base beam 11, and serves as a rolling element. Function.

  As shown in FIGS. 3, 5, and 6, in a state where the elevating beam 12 is located at the reference position, the plurality of rollers 32 are hidden by the pillow material 31 in a side view. Therefore, the transport surface 32M formed by the plurality of rollers 32 (the imaginary surface connecting the uppermost positions of the cylindrical surfaces of the plurality of rollers 32. FIG. 5) is the upper surface of the pillow 31 provided on the two base beams 11. It will be in the state located below.

  3, 4, and 5, a swing shaft 41 extending in the Y-axis direction is bridged between two longitudinal members 15 included in each leg portion 14. A lever member 42 is attached to the swing shaft 41 so as to be swingable around the swing shaft 41 (see also FIG. 6). Each lever member 42 has a rear surface 43 and an upper surface 44 which are orthogonal to each other, and has a right triangle shape as a whole in a side view.

  3, 4, and 6, the swing shaft 41 that supports each lever member 42 is positioned in the vicinity of a portion (a right angle portion) where the rear surface 43 and the upper surface 44 of the lever member 42 intersect. A pressed portion 43 </ b> T is provided at the lower portion of the rear surface 43.

  2, 3, and 5, an operation rod 51 is provided extending in the X-axis direction in a region between the two longitudinal members 15 of each leg portion 14 (a region below each lever member 42). ing. The operation rod 51 has a lower surface supported by a support roller 52 provided on the upper surface side of the lateral member 16 of each leg portion 14 (see also FIG. 6), and is movable in the X-axis direction. On the upper surface of the operation rod 51, the same number (5 in this case) of operation blocks 53 as the number of lever members 42 are provided.

  In FIG. 2, one of the plurality of leg portions 14 (here, the leg portion 14 positioned second from the front) is provided with a cylinder mounting portion 61, and a cylinder 62 is fixed to the cylinder mounting portion 61. It is fixed by a bolt 63. The cylinder 62 directs the piston rod 64 in the longitudinal direction of the base beam 11, that is, the direction parallel to the operation rod 51 (X-axis direction), and the tip of the piston rod 64 faces forward (see FIG. 2, FIG. 3, FIG. 4 and FIG. 6). The cylinder 62 is preferably an air cylinder in terms of easy handling, but may be a hydraulic cylinder.

  In FIG. 2, the tip end portion of the piston rod 64 is connected to the operation block 53 positioned in the foremost position among a plurality (here, five) of operation blocks 53. When the cylinder 62 actuates the piston rod 64, the operation block 53 connected to the piston rod 64 moves in the X-axis direction, whereby the operation rod 51 moves in the X-axis direction, and the other operation blocks 53 also move to the X-axis direction. It moves in the axial direction (FIG. 7 (a) → FIG. 7 (b) or FIG. 7 (b) → FIG. 7 (a)). As described above, in the present embodiment, the cylinder 62 pushes and pulls the plurality of operation blocks 53 directly or indirectly through the operation rod 51 by operating the piston rod 64 in the X-axis direction. Are simultaneously moved in the same direction and by the same amount.

  In the present embodiment, the cylinder 62 is used so that the piston rod 64 operates at the stroke end position on the backward side and the stroke end position on the forward side with a full stroke. For this reason, the movement distance in the X-axis direction of all the operation blocks 53 provided on the operation rod 51 matches the full stroke amount of the cylinder 62. The position of each operation block 53 when the piston rod 64 is positioned at the backward stroke end position is referred to as a “rear position” (FIGS. 7A and 8A). The position of each operation block 53 when positioned at the end position is referred to as a “front position” (FIGS. 7B and 8B).

  2 and 6, each operation block 53 is in a state of being located at the rear position, and its front surface is brought into contact with the pressed portion 43 </ b> T of the corresponding lever member 42. In a state where each operation block 53 is located at the rear position, the lever member 42 takes a posture (referred to as an “initial posture”) in which the rear surface 43 is substantially vertical and the upper surface 44 is substantially horizontal. When the lever member 42 is in the initial posture, the upper surface 44 of the lever member 42 is in surface contact with the lower surface of the elevating beam 12 located at the reference position.

  When the ascending button 23 is operated from the operation panel 21 with the elevating beam 12 positioned at the reference position, the cylinder 62 positions the piston rod 64 at the stroke end position on the forward side. As a result, all the operation blocks 53 are positioned at the front position (FIG. 7 (a) → FIG. 7 (b)).

  When the operation block 53 moves from the rear position to the front position, the pressed portion 43T of each lever member 42 is pressed forward by the operation block 53 in contact therewith (FIG. 8 (a) → FIG. 8 (b)). ). As a result, each lever member 42 swings around the swing shaft 41 from the initial position (FIG. 9A → FIG. 9B), and is tilted so as to raise the front end portion of the upper surface 44 (“tilt position”). ").

  While the lever member 42 swings from the initial posture to the tilting posture, the front end side of the upper surface 44 of the lever member 42 rises. For this reason, the elevating beam 12 is simultaneously lifted from below by a plurality of (here, five) lever members 42 and is located at a position elevated from the reference position (this position is referred to as an “elevated position”) (FIG. 10). 11 and 12).

  In a state where the elevating beam 12 is raised from the reference position and reaches the raised position, the plurality of rollers 32 are exposed above the pillow 31 in a side view. For this reason, the conveyance surface 32M formed by the plurality of rollers 32 is positioned higher than the upper surfaces of the two pillow materials 31 (FIG. 9A → FIG. 9B).

  The vertical movement distance Y (FIG. 9B) of the conveying surface 32M, which is moved when the elevating beam 12 is raised from the reference position to the raised position, is from the swing shaft 41 of the lever member 42 to the pressed portion 43T. It largely depends on the distance (L1 shown in FIG. 9A) and the distance from the swing shaft 41 to the front end portion of the upper surface 44 (L2 shown in FIG. 9A). By making the value of the ratio between L2 and L1 (ρ = L2 / L1) smaller than 1, the moving distance Y can be made smaller than the stroke of the piston rod 64. Further, by making the value of ρ smaller than 1, the output of the cylinder 62 can be amplified and transmitted to the elevating beam 12, and the maximum load weight when lifting the steel material KZ described later exceeds the output of the cylinder 62. Can be set to

  When the lowering button 24 is operated in a state where the elevating beam 12 is located at the raised position, the cylinder 62 positions the piston rod 64 from the forward stroke end position to the backward stroke end position. As a result, all the operation blocks 53 move from the front position to the rear position (FIG. 7B → FIG. 7A). When the operation block 53 is moved from the front position to the rear position, each lever member 42 swings from the tilting posture to the vicinity of the swinging shaft 64 by its own weight, and returns to the initial posture (FIG. 8 (b) → FIG. 8 (a)). ).

  When each lever member 42 returns from the tilting posture to the initial posture, the upper surface 44 of each lever member 42 is lowered at the front end side, and the elevating beam 12 is lowered to the reference position by its own weight (FIG. 9B → FIG. 9A). )). When the elevating beam 12 descends from the raised position and reaches the reference position, the plurality of rollers 32 that are exposed upward from between the two pillow materials 31 are hidden between the two pillow materials 31. It becomes. Along with this, the conveying surface 32M formed by the plurality of rollers 32 moves from a lower position to an upper position than the upper surfaces of the two pillow materials 31 (FIGS. 3, 4, and 5).

  Thus, in the columnar material support device 1 according to the present embodiment, the cylinder 62 pushes and pulls the operation block 53 with the piston rod 64, and the lever block 42 is swung around the swing shaft 41 by the operation block 53. Thus, the elevating beam 12 is raised and lowered with respect to the base beam 11 via the lever member 42. In the present embodiment, the cylinders 62, the plurality of operation blocks 53, and the plurality of lever members 42 included in each support base 10 are formed by the plurality of rollers 32 by moving the lifting beam 12 up and down relative to the base beam 11. The raising / lowering mechanism part 70 which raises / lowers the conveyance surface 32M of the steel material KZ with respect to the upper surface of the pillow material 31 is comprised.

  In the present embodiment, the two operation panels 21 provided in each of the two support bases 10 are electrically connected to each other. When the operation button 22 of one operation panel 21 is operated, the two support bases are operated by the operation. Two cylinders 62 included in 10 are moved up and down synchronously. For this reason, the operator can raise and lower the elevating beam 12 on the two support bases 10 simultaneously by operating the operation button 22 from one of the two operation panels 21.

  In the columnar material support apparatus 1 according to the present embodiment, the two support bases 10 extend in a direction perpendicular to the direction of the steel material KZ to be supported in a horizontal plane and are previously on the floor surface so as to be parallel to each other. Set. At this time, the interval between the two support bases 10 is set to an appropriate interval that can stably support the steel material KZ to be supported. As described above, since the caster 18 is provided on the leg portion 14 of each support base 10, the operator can adjust the distance between the two support bases 10 very easily.

  As described above, when the steel material KZ is suspended by the overhead crane (not shown) and supported by the columnar material support device 1, the operator operates the operation button 22 from the operation panel 21 to position the lift beam 12 at the reference position. The transport surface 32M of each support base 10 is previously positioned below the upper surface of the pillow material 31. Thus, the lower surface of the steel material KZ suspended is brought into contact with the cushioning material 31 instead of the roller 32, and the roller 32 is damaged or deformed due to damage (impact) from the steel material KZ. Is prevented.

  After the columnar material support device 1 supports the steel material KZ, the operator moves the steel material KZ in the horizontal direction (the direction in which the steel material KZ extends is orthogonal to the horizontal plane, in this case, the X-axis direction) ( This may be referred to as a repositioning operation of the steel material KZ). When performing the repositioning operation of the steel material KZ, the operator operates the ascending button 23 from the operation panel 21 to raise the elevating beam 12 from the reference position to the ascending position. As a result, the conveying surface 32M of each support base 10 is positioned above the upper surface of the pillow material 31, and the steel material KZ is lifted by the elevating beam 12 via the roller 32 (FIG. 9 (a) → FIG. 9). (B)).

  In a state where the steel material KZ is lifted by the elevating beam 12 via the roller 32, if the steel material KZ is pressed in the direction in which the steel material KZ is desired to move, the steel material KZ advances in the direction pressed by the rolling of the roller 32. For this reason, the operator can move the steel material KZ, which is a heavy object, on the columnar material support device 1 easily and in a short time by simply pressing the central portion of the steel material KZ from between the two support bases 10. FIG. 13 shows a state where the operator OP presses one of the steel materials KZ and moves it alone to the front of the columnar material support device 1.

  In the above-described repositioning work of the steel material KZ, the operator pays attention so that the pressed steel material KZ does not reach the end of the support 10. As described above, the rod-like member 20 can be attached to the end plate 19 of each support base 10, and in the state where the rod-like member 20 is attached to the end plate 19, the rod-like member 20 serves as a stopper for the steel material KZ. To play a role. For this reason, even if the steel material KZ pressed by the operator accidentally reaches the end portion of the support base 10, the steel material KZ falls off from the end portion (longitudinal end portion) of the support base 10. There is no end to it. That is, in the present embodiment, the rod-shaped member 20 is a drop-off preventing member that prevents the steel material KZ from dropping off from the end of the support base 10.

  As described above, in the columnar material support device 1 according to the present embodiment, each of the two support bases 10 that support the steel material KZ that is the columnar material in a posture extending in the horizontal direction is formed by the plurality of rollers 32. The conveyance surface 32M can be moved up and down relatively with respect to the upper surface of the pillow 31. For this reason, it is possible to make the steel material KZ supported by the roller 32 by positioning the transport surface 32M above the upper surface of the pillow material 31, and moving the steel material KZ in the lateral direction while rolling the roller 32. The position of the steel material KZ can be easily changed in a short time. Further, by positioning the conveying surface 32M below the pillow material 31, the roller 32 can be prevented from receiving a large impact from the steel material KZ when the steel material KZ is suspended, and the roller 32 can be damaged or deformed. Can be prevented.

  Further, since the cylinder 62 is disposed in the lateral direction in which the piston rod 64 faces the longitudinal direction (that is, the horizontal direction) of the base beam 11, the overall height of the columnar material support device 1 can be kept small. Moreover, since the cylinder 62 with a large size can be used, the output required for lifting the steel material KZ can be secured. Furthermore, since the cylinder 62 can be used with a full stroke, a structure for limiting the stroke of the cylinder 62 and a structure for detecting the position of the piston rod are unnecessary, and the manufacturing cost is reduced. Can do.

  Although the embodiment of the present invention has been described so far, the present invention is not limited to the above. For example, the pillow material 31 only needs to be disposed on one upper surface of the base beam 11 and the lifting beam 12 so as to extend in the longitudinal direction of the base beam 11, and the plurality of rollers 32 can be used as the other of the base beam 11 and the lifting beam 12. It suffices if they are provided on one upper surface side by side in the longitudinal direction of the base beam 11. Therefore, the pillow material 31 may be disposed on the upper surface of the elevating beam 12, and the plurality of rollers 32 may be disposed on the upper surface of the base beam 11. In such a configuration, with the lifting beam 12 positioned at the reference position, the upper surface of the pillow material 31 is positioned lower than the conveying surface 32M, and the lifting beam 12 is positioned at the rising position. The pillow 31 is positioned higher than the transport surface 32M. Even in such a configuration, each of the two support bases 10 has a configuration in which the conveyance surface 32M formed by the plurality of rollers 32 is moved up and down relatively with respect to the upper surface of the pillow material 31. The same effect as that of the case of can be obtained.

  Moreover, in the above-mentioned embodiment, although the number of the support bases 10 was two, this is an example and three or more may be sufficient. The rolling element may not be the roller 32 but may be a sphere. If the rolling element is a sphere, it is possible to move the supported steel material KZ not only in the horizontal direction but also in the vertical direction (direction in which the steel material KZ extends).

  In the above-described embodiment, the cylinder 62 drives the lever member 42 by the piston rod 64 and swings the lever member 42 about the swinging shaft 41 extending in the horizontal direction perpendicular to the longitudinal direction of the base beam 11. Although the lifting beam 12 is raised and lowered with respect to the base beam 11, this is merely an example of a driving mechanism for raising and lowering the lifting beam 12 by the cylinder 62. For example, the cylinder 62 may be configured to move up and down with respect to the base beam 11 by directly driving the lifting beam 12 by the upward movement of the piston rod 64.

  Further, in the above-described embodiment, the lifting mechanism 12 moves the transporting surface 32 </ b> M formed by the plurality of rollers 32 up and down relative to the upper surface of the pillow 31 by moving the lifting beam 12 up and down with respect to the base beam 11. As an example, the cylinder 62 is provided as an actuator, but the elevating mechanism 70 may be provided with a motor as an actuator instead of the cylinder 62. When the elevating mechanism unit 70 includes a motor as an actuator, the ball screw extending in the vertical direction is driven by the motor to elevate the elevating beam 12.

  In the above-described embodiment, each of the plurality of support bases 10 includes the casters 18 and can move on the floor surface independently of each other. However, this is not essential. The plurality of support bases 10 may be configured to be close to and away from each other on a frame installed on the floor surface, or the plurality of support bases 10 may be relatively fixed.

  In the above-described embodiment, the steel material KZ is shown as the columnar material, but this is only an example. The columnar material support device 1 of the present invention is not limited to the steel material KZ, but can be applied to all columnar materials including wood and the like, in addition to those made of metals other than steel.

  Provided is a columnar material support device capable of easily and in a short time changing the position of a columnar material supported in a horizontally extending posture.
