Description

  The present invention relates to Wilkie. In particular, the present invention relates to the structure of Wilkie, which is a special-purpose tool for turning a handle for opening and closing a manual valve.

  In thermal power plants and chemical plants, many pipes are laid to transfer various fluids and gases. And the flow control valve which adjusts the flow volume of these piping, and the on-off valve which opens and closes the flow path of piping are arrange | positioned everywhere. As the on-off valve, for example, a manual valve is used. The manual valve can open and close the pipe flow path by turning the handle.

  A manual valve used in a thermal power plant or a chemical plant has a long period of time when it is kept in a closed state or in an open state, and it is often difficult to rotate a handle. In addition, a manual valve that opens and closes a high-pressure incompressible fluid often has difficulty in rotating a handle. Therefore, it is difficult to rotate the handle manually. For this reason, the handle is rotated using a Wilky key during periodic inspections. This is because the rotational torque of the handle can be increased by locking the Wilky to the handle.

  As such a Wilkie, a versatile Wilkie that can handle a plurality of types of handles having different diameters is disclosed (for example, see Patent Document 1).

  The Wilky by patent document 1 is equipped with the elongate operating rod, and the fixed arm and the movable arm are extended from this operating rod. The movable arm is slidably attached to the operating rod, and is configured to be movable back and forth with respect to the fixed arm. The fixed arm and the movable arm are arranged so as to extend outward from the operation rod. The Wilkie according to Patent Literature 1 eliminates the need to carry a plurality of types of Wilkie to the site, and can handle handles having different diameters with a single Wilkie.

  On the other hand, the Wilkey according to Patent Document 1 is suitable for the operation of a handle having a relatively large diameter, but is not suitable for the operation of a handle having a small diameter that is gripped and rotated by the palm of one human hand. there were. In particular, since the Wilkey according to Patent Document 1 grips the operating rod and rotates the handle, it is difficult to adjust the force. When applied to a small-diameter handle operation, an excessive torque is applied to the handle shaft. There was a concern of damaging parts or the valve itself.

  In order to eliminate the above-mentioned problems, not only can the handle rotation by manual operation be facilitated, but also the operability is good regardless of the presence or absence of obstacles around the handle, and because it is compact and lightweight. In addition, there is disclosed a small-sized wheel key for operating a handle that is excellent in portability and can be adjusted in force, so that the handle is not damaged (see, for example, Patent Document 2).

  FIG. 7 is a perspective view showing a general Wilky configuration according to the prior art. FIG. 8 is a perspective view showing a state in which a handle is rotated in a direction in which a manual valve is closed using a general Wilky according to the prior art. FIG. 9 is a perspective view showing a state in which a general Wilky according to the prior art is detached from the handle.

  Referring to FIGS. 7 to 9, the Wilky 8 includes a long operation rod 80 and short first arms 81 and second arms 82. The operating rod 80 has a gripping portion 8a on one end side. The first arm 81 is refracted at a substantially right angle from the terminal end on the other end side of the operating rod 80. The first arm 81 extends in a direction substantially orthogonal to the longitudinal direction of the operating rod 80.

  Referring to FIGS. 7 to 9, the second arm 82 is disposed with a predetermined distance from the first arm 81. The second arm 82 extends from the operating rod 80 so as to be substantially parallel to the first arm 81. The operating rod 80, the first arm 81, and the second arm 82 are integrally formed by forging, for example. Generally, the Wilky 8 is a rigid tool with little deformation.

  Referring to FIG. 8, the manual valve 9 includes a rotatable handle 90. The handle 90 has a disc-shaped hub 92, a plurality of spokes 93, and an annular rim 94. The hub 92 is screwed to the stem 91. The spokes 93 extend radially around the hub 92. The rim 94 is coupled to the extended end of the spoke 93. The manual valve 9 can be opened and closed by rotating the handle 90 using the Wilky 8.

  Referring to FIG. 8, the first arm 81 is brought into contact with the inside of the spoke 93 and the rim 94, the second arm 82 is brought into contact with the outer side of the rim 94, and the operation rod 80 is pulled in the centrifugal direction of the handle 90. The manual valve 9 can be closed by pulling to the side and rotating the handle 90 clockwise.

  On the other hand, referring to FIG. 8, the first arm 81 contacts the inside of the spoke 93 and the rim 94, the second arm 82 contacts the outside of the rim 94, and the operating rod 80 is pulled in the centrifugal direction of the handle 90. The manual valve 9 can be opened by pushing it back and rotating the handle 90 counterclockwise.

  Referring to FIG. 8, the Wilky 8 does not straddle the center of the handle 90. Further, since the first arm 81 and the second arm 82 extend straight with respect to the operating rod 80, the attachment to and detachment from the handle 90 is easy.

  Since the handle 90 shown in FIG. 8 is disposed at the height of the waist of the operator, it is relatively easy to rotate the wheelie 8 by engaging the handle 90. On the other hand, since the handle 90 shown in FIG. 9 is disposed at the height of the operator's head, it is relatively difficult to rotate the wheelie 8 by engaging the handle 90. Referring to FIG. 9, since the first arm 81 and the second arm 82 are in point contact with the rim 94 having a curved surface, it may be easily detached from the handle 90.

  The Wilky 8 shown in FIGS. 7 to 9 is suitable for the operation of a handle having a relatively large diameter, but is not suitable for the operation of a handle having a small diameter enough to be gripped and rotated by the palm of one human hand. . Since the illustrated Wilkey 8 rotates the handle 90 while gripping the operating rod 80, it is difficult to adjust the force. When applied to a small-diameter handle operation, an excessive torque is applied to the shaft of the handle 90. There was a concern of damaging the parts or the valve itself.

  FIG. 10 is a perspective view showing the configuration of a Wilky suitable for operating a small-diameter handle. FIG. 10A is a state diagram before the Wilky is engaged with the handle, and FIG. FIG. 10C is a state diagram in which the handle is rotated while holding the Wilky with one hand.

  FIGS. 11A and 11B are views showing a configuration of a Wilkie suitable for operating a small-diameter handle, FIG. 11A is a plan view of the Wilkie, and FIG. 11B is a front view of the Wilkie. FIG. 12 is a plan view showing a modified example of the Wilkie shown in FIG.

  Note that FIG. 10 of the present application corresponds to FIG. Further, FIG. 11 of the present application corresponds to FIG. 2 of Patent Document 2, and FIG. 12 of the present application corresponds to FIG. 7 of Patent Document 2.

  Referring to FIG. 10 or FIG. 11, the Wilky 6 includes a substantially circular gripping plate 61 and a plurality of columnar engaging protrusions 62. The holding plate 61 is formed so that its outer diameter is larger than the outer diameter of the handle 70. In addition, the holding plate 61 has a plurality of depressions 61d arranged at equal intervals on the outer periphery thereof. By providing the plurality of depressions 61d on the outer periphery of the gripping plate 61, the gripping plate 61 can be rotated with one hand H without sliding the gripping plate 61 (see FIG. 10C). Further, the engagement protrusion 62 protrudes from one surface of the gripping plate 61.

  Referring to FIG. 10, the valve 7 includes a rotatable handle 70. The handle 70 has a hub 72, a plurality of spokes 73, and an annular rim 74. The hub 72 is formed at the tip of the stem 71. The spokes 93 extend radially around the hub 92. The rim 94 is coupled to the extended end of the spoke 93. The engaging protrusion 62 can be inserted into a space defined by the rim 94 and the spoke 93.

  From the state shown in FIG. 10A, the gripping plate 61 is placed on the rim 74, and the engaging protrusion 62 is inserted into the space defined by the rim 94 and the spoke 93 (see FIG. 10B). Next, the handle 70 can be rotated by holding the holding plate 61 with one hand H and rotating the holding plate 61 around the axis of the stem 71. Then, the valve 7 can be opened and closed.

  Referring to FIG. 12, the Wilky 60 according to the modification further includes a handle 63. The small handle 63 protrudes from the outer periphery of the holding plate 61 in the centrifugal direction. The Wilky 60 can increase the rotational torque of the handle 70 and easily open and close the valve 7 by providing the small handle 63 when the handle 70 is rotated while holding the grip plate 61 with one hand H.

  When the small-diameter handle 70 shown in FIG. 10A is rotated using the Wilky 8 shown in FIGS. 7 to 9, unnecessary force acts on a pipe (not shown) connected to the valve 7. There is a concern of deforming the piping. As described above, the Wilky 8 according to the prior art rotates the handle 90 while pulling in the centrifugal direction of the handle 90, so there is a concern that deformation such as torsion or deflection occurs in the pipe.

  On the other hand, in the Wilky 6 shown in FIG. 10 or FIG. 11 or the Wilky 60 shown in FIG. 12, only the force for rotating the stem 71 acts on the pipe (not shown) connected to the valve 7, so that the pipe is deformed. It is thought that there is little worry to make.

  However, referring to FIGS. 10 and 11, the Wilky 6 or the Wilky 60 can be applied only to a handle having a size that can be gripped with one hand H, and when the stem 71 is firmly fastened to the valve 7, There is a problem that the rotational torque that loosens this is insufficient. There is a need for a Wilkie that can easily open and close the valve without deforming the piping connected to the valve. The above can be said to be the subject of the present invention.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a Wilky that can easily open and close a manual valve without deforming a pipe connected to the manual valve.

  The inventors of the present invention configured a Wilky with a disk, a pair of operating rods extending in the centrifugal direction of the disc, and a pair of engaging arms extending from an intermediate portion of the operating rod. A pair of operating rods are brought into contact with the upper surface of the handle so that the central portions coincide with each other, the end portions of the operating rod are gripped with both hands, the pair of operating rods are rotated around the disk, and the pair of engaging arms are Therefore, only the rotational torque of the stem is considered to act on the manual valve, and based on this, the following new Wilkie has been invented.

A wheelie that opens and closes the manual valve by rotating a handle having an annular rim around the axis of the stem, a disc that can freely contact one surface of the hub, and a centrifugal direction from the disc A pair of operating rods extending in directions opposite to each other and extending beyond the outer circumference of the rim, and extending in parallel from the intermediate portion of the operating rod approximately perpendicular to the direction in which these operating rods extend, A pair of short engagement arms that can be brought into contact with the outer periphery, and the pair of operating rods have a gripping portion that can be gripped with both hands at the end.

  (2) The handle has an extended end portion of the stem that protrudes from one surface of the hub, and the disk has a fitting hole that is rotatably fitted to the extended end portion as a central portion. An opening is preferred.

  (3) The grip portion may include a rod-shaped grip portion continuous from the operation rod.

  (4) One of the grip portions has a rod-shaped first knob that is bent at a substantially right angle from a distal end portion of the operation rod and extends in the same direction as the direction in which the engagement arm extends, and the other grip portion is The second knob may have a rod-like second knob that is bent at a substantially right angle from a distal end portion of the operating rod and extends in a direction opposite to a direction in which the engagement arm extends.

  (5) The grip portion may include a spherical third knob formed at a terminal portion of the operation rod.

  (6) The grip portion may include a spherical fourth knob disposed in a direction opposite to a direction in which the engagement arm extends.

  The Wilky according to the present invention includes a disk that can freely come into contact with one surface of the hub, a pair of operating rods extending in a direction opposite to the centrifugal direction from the disc, and extending in parallel from an intermediate portion of the operating rod. A pair of engaging arms that can freely come into contact with the outer periphery, grip the end portion of the operating rod with both hands, rotate the pair of operating rods around the disk, and rotate the stem through the pair of engaging arms. By rotating, only the rotational torque of the stem acts on the manual valve, so that the manual valve can be easily opened and closed without deforming the pipe connected to the manual valve.

The disk 41 can abut on one surface of the hub 52 (see FIG. 2). The pair of operating rods 42 and 42 extend from the disc 41 in opposite directions in the centrifugal direction. The pair of operating rods 42 and 42 have a length exceeding the outer periphery of the rim 54 (see FIG. 3).

  Referring to FIG. 6, the pair of engagement arms 43 and 43 extend in parallel from the intermediate portion of the operation rod 42 substantially perpendicular to the direction in which the operation rod 42 extends. And a pair of engagement arms 43 * 43 can contact | abut to the outer periphery of the spoke 53 (refer FIG. 3 (A)). The pair of operating rods 42 and 42 have grip portions 421 and 421 at their end portions that can be gripped with both hands.

  Referring to FIG. 6, the grip portion 421 has a spherical fourth knob k4. The pair of fourth knobs k4 and k4 are arranged in a direction opposite to the direction in which the engagement arm 43 extends.

  Referring to FIG. 6, the disk 41 has a fitting hole 41h open at the center. The extended end 511 can be inserted into the fitting hole 41h, and can be rotatably fitted to the extended end 511.

(Wilky's action)
Next, the operation and effect of the Wilky 40 will be described while explaining the operation method of the Wilky 40 according to the fourth embodiment.

  While referring to FIG. 2 or FIG. 3B and referring to FIG. 6, first, the Wilky 40 is moved toward the handle 50 so that the pair of engagement arms 43 and 43 are opposed to the handle 50. . Next, the extended end portion 511 is inserted into the fitting hole 41h, the fourth knobs k4 and k4 of the pair of operating rods 42 and 42 are gripped with both hands, and the pair of operating rods 42 and 42 are centered on the disk 41. By rotating in the clockwise direction R (see FIG. 3A), the stem 51 can be rotated in the clockwise direction R via the pair of engagement arms 43 and 43. Then, the manual valve 5 can be closed.

  On the other hand, while referring to FIG. 2 or FIG. 3 (B) and referring to FIG. 6, the extended end portion 511 is inserted into the fitting hole 41h, and the fourth knobs k4 and k4 of the pair of operating rods 42 and 42 are inserted. Is gripped with both hands, and the pair of operating rods 42 and 42 are rotated counterclockwise L around the disk 41 (see FIG. 3A), whereby the stem 51 is interposed via the pair of engaging arms 43 and 43. Can be rotated counterclockwise L. Then, the manual valve 5 can be opened.

  Referring to FIG. 6, the Wilky 40 according to the fourth embodiment has the same effects as the Wilky 10, 20, 30 according to the first to third embodiments, but the spherical fourth knob k4 is a palm. It is easy to grasp and grips the pair of fourth knobs k4 and k4 and presses the pair of operating rods 42 and 42 against the rim 54 (see FIG. 2) while rotating the pair of engaging arms 43 and 43 around the disk 41. There is a special effect that it is easy to do.

  In the Wilky according to the present invention, the pair of operating rods has a length exceeding the outer circumference of the rim, and therefore, the rotational torque of the stem can be increased by gripping and rotating the end portions of the pair of operating rods. effective.

  In addition, the Wilky according to the present invention is a manual type valve by grasping the end portion of the operating rod with both hands, rotating the pair of operating rods around the disk, and rotating the stem via the pair of engaging arms. Since only the rotational torque of the stem acts, there is an effect that the manual valve can be easily opened and closed without deforming the pipe connected to the manual valve.
