Description

  The present invention relates to a hanging tool used by being connected to a hook that is lifted and lowered by a crane or the like in a factory.

  Conventionally, when moving a heavy work (for example, steel) in a factory, after attaching a sling or wire attached to the work to a hook of a crane provided in the factory, The lifting and lowering operation of the hook by the crane and the traveling operation of the crane are performed in parallel (for example, Patent Document 1 below). In addition, when rotating a workpiece (for example, upside down), a cord-like object hung around the workpiece is attached to the hook, the hook is lifted by a crane, and the workpiece is rotated with one corner of the workpiece as a fulcrum. It was. At this time, it was necessary to operate the crane so that the hook draws an arc-shaped trajectory, or to lift the cord-like object at a position eccentric with respect to the position of the center of gravity of the work, and high skill was required.

  The present inventor has found a new work rotation procedure instead of the conventional work rotation method. A pulley device is attached to each of the two cranes, and both ends of the workpiece are supported from below by a ring-shaped cable attached to the ring wheel of these two pulley devices, and then the workpiece is lifted to a horizontal posture. After being rotated manually, it is lowered to the original position. This is a very simple method of rotating the workpiece, but the work of attaching and removing the pulley device to and from the crane hook is very troublesome and time consuming, and the simple movement and rotation of the workpiece are alternated. When it is necessary to repeatedly carry out, there is also a problem that workability is not good because the pulley device is frequently attached to and detached from the hook.

  Then, an object of this invention is to provide the hanging tool which can perform efficiently the operation | work which implements alternately the movement operation | work of a workpiece | work and a rotation operation | work.

  The hanging device according to the present invention includes a base body connected to a hook that is raised and lowered, a shaft member that extends horizontally in a cantilevered manner from the base body, and is rotatably provided on the shaft member. A rope having a guide surface for guiding an object, a bracket having an upper end attached to the shaft member and depending on its own weight, and a hook member having an upper end attached to the bracket. The cord-like object can be attached to and detached from the guide surface of the cable ring from the end side.

  According to the present invention, it is possible to efficiently perform work of alternately performing work movement work and rotation work.

  Embodiments of the present invention will be described below with reference to the drawings. 1, 2, and 3, the hanging tool 1 according to the present embodiment includes a base body 11, a shaft member 12, a rope 13, a bracket 14, and a hook member 15. The base body 11 includes a flat plate-like main portion 11a extending in the vertical direction as a whole, two side portions 11b located on both sides of the main portion 11a, a substantially horizontal ceiling portion 11c and a ceiling portion 11c located above the main portion. It has the extension part 11d provided extended from the upper part. A rib portion 11e as a reinforcing material is bridged between the ceiling portion 11c and the extending portion 11d. The extending part 11d is provided with a connecting part 11R made of a circular hole.

  2 and 3, one end of the shaft member 12 is connected to a flat plate-shaped shaft member base 12a, and the shaft member 12 extends orthogonally to the shaft member base 12a. The shaft member base 12a is fastened to the main portion 11a of the base body 11 by a plurality of fastening screws 12b. As a result, the shaft member 12 extends horizontally from the main portion 11a of the base body 11 in a cantilever posture.

  2 and 3, the rope 13 is rotatably attached to the shaft member 12 via a radial bearing 13B. The rope 13 is provided with a cylindrical portion 13a in which the central axis of the shaft member 12 and the axis coincide with each other, and two disk portions 13b located between the cylindrical portion 13a. The two disk portions 13b are provided concentrically with the cylindrical portion 13a. The diameters of the two disk parts 13b are both larger than the diameter of the cylindrical part 13a. A sling SL as a cord-like object described later is detachably attached to the rope 13. In a state where the sling SL is attached to the ring ring 13, the outer peripheral surface of the cylindrical portion 13 a functions as the guide surface 13 </ b> M of the sling SL in the ring ring 13.

  1, 2, and 3, the bracket 14 includes a pair of vertical portions 14 a and a horizontal portion 14 b that connects lower ends of the pair of vertical portions 14 a. The pair of vertical portions 14a has a hole 14H provided at an upper end thereof loosely fitted to the shaft member 12, and the bracket 14 is entirely suspended by its own weight. The pair of vertical portions 14 a is located with the rope 13 interposed therebetween, and the horizontal portion 14 b is located below the rope 13. A pad member 12c is attached to the free end of the shaft member 12 by a plurality of screw members 12d. The pad member 12c prevents the bracket 14 from coming out of the shaft member 12.

  1, 2, and 3, the hook member 15 has an upper end attached to the horizontal portion 14 b of the bracket 14. Specifically, a screw portion 15 a (FIG. 3) provided at the upper end portion of the hook member 15 penetrates the thrust bearing 16 attached to the horizontal portion 14 b of the bracket 14 from below, and penetrates the thrust bearing 16. A nut 17 is screwed onto the end of the threaded portion 15a.

  2 and 3, a grooved nut 18 and a split pin 19 are further attached to the screw portion 15a of the hook member 15, and the rotation of the nut 17 with respect to the screw portion 15a is prevented. Since the hook member 15 is attached to the horizontal portion 14b via the thrust bearing 16, the hook member 15 can freely rotate about the vertical axis with respect to the horizontal portion 14b.

  As shown in FIGS. 4 and 5, a crane-side hook H provided in the factory is directly (or via another connector) connected to the connecting portion 11 </ b> R provided in the extending portion 11 d of the base body 11. And indirectly). Further, as shown in FIGS. 4 and 5, a sling SL as a rope-like object can be attached to and detached from the outer peripheral portion (that is, the guide surface 13M) of the rope 13 as needed (in FIG. 4). Arrow T shown).

  Here, since the shaft member 12 extends in a cantilevered manner from the base body 11 and the upper portion of the rope 13 is in an open state, even if the sling SL is annular, the sling SL is It can be easily attached to and detached from the rope 13. The sling SL attached to the rope 13 is restricted in movement in the width direction by the two disk portions 13b so as not to drop off from the guide surface 13M of the rope 13 (the outer peripheral surface of the cylindrical portion 13a).

  The hook member 15 can be attached with other cords or other suspension tools. FIG. 5 shows an example in which a master ring MR is attached to the hook member 15 and two chain hooks CH are attached to the master ring MR.

  Next, the usage example of the hanging tool 1 in this Embodiment is demonstrated using FIGS. 6 and 7 are examples of use (hanging) in which the work W (for example, steel) placed on the work table SD installed in the factory is moved in the lateral direction to change the placement position on the work table SD. An example of use of the tool 1 as a hook) is shown. FIG. 8 shows an example of use in which the work W placed on the work table SD is once lifted and then turned upside down and lowered to the original position (use example of the lifting tool 1 as a pulley device). ).

  First, a case where the workpiece W is moved in the horizontal direction will be described. When the workpiece W is simply moved in the lateral direction, it is important to lift the workpiece W in a horizontal posture so that the workpiece W does not rotate around the axis. For this reason, the operator either directly connects both ends of the sling SL hung around the end of the workpiece W to the hook member 15 of the hanging tool 1 (FIG. 6) or attaches the hook member 15 to the hook member 15 via the master ring MR. It is connected to the chain hook CH (FIG. 7). Then, in this state, the two hooks H in the factory are simultaneously raised and moved to the side (arrow A shown in FIGS. 6 and 7), and the two hooks H are simultaneously lowered to move the workpiece W. Lower it on the workbench SD in a horizontal position.

  On the other hand, when the work W is turned upside down, an annular sling SL attached to the rope 13 of the hanger 1 is hung around the end of the work W (FIG. 8). Then, the two hooks H are simultaneously lifted to lift the workpiece W in a horizontal posture, and then the operator manually rotates the workpiece (FIG. 9 (a) → FIG. 9 (b) → FIG. 9 (c). ). In response to the rotation of the workpiece W around the axis, the rope 13 of each of the two hanging tools 1 rotates around the shaft member 12, and the workpiece W remains in a state where it is suspended in a horizontal posture by two slings SL. Rotate around. As a result, when the workpiece W is turned upside down, the two hooks H are lowered at the same time, and the workpiece W is lowered onto the work table SD in a horizontal posture. According to such a procedure, the work W can be easily turned upside down.

  In the hanging tool 1 according to the present embodiment, the bracket 14 is suspended by its own weight with respect to the shaft member 12, so that, for example, the crane that suspends the hanging tool 1 vibrates and the base body 11 is laterally moved ( Even when it is tilted (about an axis parallel to the axis of the shaft member 12) (FIG. 10), the bracket 14 maintains the hanging position, and the mounting position of the hook member 15 on the bracket 14 is directly below the shaft member 12. Does not move from the position. For this reason, even if the sling SL is attached to the rope 13, the bracket 14 and the hook member 15 do not interfere with the sling SL, and the sling SL is not damaged. If the hook member 15 is attached to the bracket 14 fixed to the base body 11 or directly attached to the base body 11, the hook member 15 is not attached to the base body 11 when the base body 11 is inclined. There is a possibility that the mounting position moves in the lateral direction and interferes with the sling SL and damages the sling SL (see the hook member 15 indicated by a one-dot chain line in FIG. 10).

  As described above, the hanger 1 according to the present embodiment includes the guide surface 13M of the sling SL on the shaft member 12 that extends horizontally in a cantilevered manner from the base body 11 that is connected to the hook H that is raised and lowered. The rope 13 is provided, and by attaching the sling SL to the rope 13, the hanging tool 1 can be used as a pulley device. At this time, the sling SL can be attached and detached from the space above the cable ring 13 in an open state, and even if the sling SL is in an annular shape, the sling SL can be easily attached to the cable ring 13. Can be attached or removed.

  In addition, a bracket that is suspended by its own weight is attached to the shaft member 12, and a hook member 15 is attached to the bracket. For this reason, even if it is a case where the hanging tool 1 is connected with the hook H for using as a pulley apparatus, it can be used as a hook, without removing the hanging tool 1 from the hook H.

  As described above, the hanging tool 1 according to the present embodiment can be used as a hook or a pulley device, and an operation that requires a hook (for example, a work moving operation) and an operation that requires a pulley device (for example, rotation of a workpiece). It is not necessary to attach or remove the pulley device to the hook on the crane side. For this reason, it is necessary to attach or detach the lifting tool 1 to or from the hook H of the crane when performing an operation of alternately performing a moving operation of a workpiece requiring a hook and a rotating operation of a workpiece requiring a pulley device. Therefore, such work can be performed efficiently. In the above-described embodiment, the example in which the workpiece W is turned upside down using the hanging tool 1 has been described. However, the hanging tool 1 is not only used for turning the workpiece W upside down (the rotation angle of the workpiece W is 180 degrees). Of course, it can also be used when the workpiece W is to be rotated at an arbitrary angle.

  Further, in the hanging tool 1 according to the present embodiment, the bracket 14 to which the hook member 15 is attached is configured to hang down by its own weight with respect to the shaft member 12, so that the base body 11 is attached to the shaft member for some reason. Even in a case where the posture is inclined about an axis parallel to the 12 axis, the bracket 14 and the hook member 15 attached thereto maintain the hanging posture. For this reason, even if the base body 11 is inclined, the bracket 14 and the hook member 15 do not interfere with the sling SL and do not damage the sling SL, so that the sling SL can be used as a hook with the sling SL attached. It is possible and suitable for the mixed use (alternate use) of the use of the hanging tool 1 as a hook and the use as a pulley device.

  Although the embodiments of the present invention have been described so far, the present invention is not limited to the above-described ones. For example, in the above-described embodiment, the sling SL is exemplified as the cord-like object, but the cord-like object is not limited to the sling SL, and may be a wire, a rope, or the like. The hook member 15 attached to the bracket 14 may be an o-hook.

  In the above-described embodiment, the bracket 14 has a configuration including a pair of vertical portions 14a positioned with the rope 13 interposed therebetween and a horizontal portion 14b connecting the lower ends of the pair of vertical portions 14a. In such a configuration, in the case where the design is changed to use the rope 13 having a different dimension in the thickness direction, since common parts can be used, the productivity is good. However, the bracket 14 is a shaft member. The structure is not particularly limited as long as it is attached to 12 and hangs down by its own weight.

  An object of the present invention is to provide a hanging tool capable of efficiently performing a work for alternately moving and rotating a work.
