Description

  The present invention relates to a rotating tool for a ring-shaped handle, and more particularly to a device for rotating a ring-shaped handle by hooking a pair of protrusions at the tip of a rod-shaped member.

  In plants such as power plants, ring-shaped handles for manually operating large and small valves are installed in various places. The larger the diameter of this wheel handle, the greater the rotational load. Therefore, when a worker must work alone, the wheel handle is generally rotated using a rotating tool for wheel handles that uses the lever principle. Is.

For example, as shown in FIG. 5, this type of rotating handle for a ring-shaped handle includes a pair of first and second projecting bars 111 and 112 that project in the orthogonal direction to the tip of an operation bar 101 that grips one end side. The so-called Wilki 100 is known. As shown in FIG. 6, the Wilki 100 inserts the first and second protruding rods 111 and 112 so as to straddle the spokes S that support the ring-shaped handle H, and the first and second protruding rods 111 and 112 are inserted. As a fulcrum and a force point, an operation is performed so that one end side of the operation rod 101 to be gripped is an action point (see Patent Document 1).
In this Wilki 100, since the distance between the first and second protruding rods 111 and 112 is fixed, the size of the ring-shaped handle H that can be operated is determined to some extent, so that the optimum type is selected and prepared each time. It may be necessary to carry around, and in some cases, it may be necessary to carry multiple pieces. In such a case, the work load is large, which is also a factor of lowering work efficiency.

  For this reason, Patent Document 2 proposes a Wilki that includes first and second protruding rods having different intervals on both ends of the operating rod. Further, Patent Document 3 proposes a wiki that employs a slide structure in which the first projecting rod on the distal end side can be moved close to and away from the second projecting rod, and the interval is tightened and fixed with a screw.

Is attached. The cylindrical portion 55 of the first tip portion 53 is formed with a tapered surface 55a in which the opening inner surface on the tip end side enlarges the opening area toward the end portion, and the built-in screw 60 is placed in the columnar space 56 ′. It can be easily guided when setting.
Accordingly, the operating rod 11 can rotate the male screw portion 67 of the built-in screw 60 in the second distal end portion 54 in the forward / reverse direction only by rotating the operation portion 61 at the proximal end in the forward / reverse direction. It is possible to slide the meshing position of the first threaded portion 67 of the first tip portion 53 with the female screw portion 58 of the cylindrical portion 55 in the length direction, and the first and second projecting rods 21 of each other. , 22 can be adjusted.

  Therefore, in the Wilki 50, the first projecting rod 21 (first distal end portion 53) can be moved into the second projecting rod 22 (second distal end portion 54) simply by rotating the operation portion 61 at the proximal end of the operation rod 11. Can be moved in the length direction, and the distance between them can be adjusted so as to be positioned at the corners of the ring-shaped handle H or spoke S to be worked.

  As described above, in the present embodiment, as in the above-described embodiment, the ring-shaped handle is obtained by rotating the operation unit 61 without relatively rotating the first and second protruding rods 21 and 22 at the tip of the operation rod 11. It is possible to adjust the separation interval so that the rotation operation of H can be easily performed, and it is not necessary to prepare a plurality of types of Wilki for each size of the ring-shaped handle H. Furthermore, it has a structure in which the tip portion does not easily fall off, and the safety of work can be improved. Therefore, it is possible to provide the wiki 10 that is highly versatile, easy to adjust, and safer.

(Fourth embodiment)
FIG. 4 is a view showing a fourth embodiment of the rotary handle for a ring-shaped handle according to the present invention.
In FIG. 4, the illuminator 70 is provided with an operation rod 11 and first and second projecting rods 21 and 22, as well as the illuminator 10 of the above-described embodiment, and in addition to this, a built-in screw 80 is provided. In this structure, the stopper screw 25 is not required to be attached.

And the operating rod 11 of this embodiment is equipped with the 1st, 2nd front-end | tip parts 73 and 74 at the front end side like the above-mentioned embodiment.
The second tip 74 is perforated so that the columnar space 76 is opened in the cylindrical rod-like tip surface with the gripper 12 side main body extended, and is continuous with the columnar space 76. Slide grooves 79 are formed on both sides (a pair of upper and lower sides in FIG. 4) centering on the axis of the lever. The slide groove 79 is extended in the length direction so as to accommodate an insertion shape portion 75 on the first tip portion 73 side described later.
The first tip portion 73 is made of a cylindrical member having the same diameter as a separate body from the main body portion on the grip portion 12 side, and the end surface of the first tip portion 73 on the second tip portion 74 side has a cylinder. A pair of insertion shape portions 75 extending in the same direction so as to be inserted into a slide groove 79 continuous to the shape space 76 are integrally formed.
As a result, the first tip portion 73 inserts the insertion shape portion 75 into the slide groove 79 in the second tip portion 74 and approaches the second tip portion 74 in the length direction of the operating rod 11 or It can be connected so as to be relatively movable in the direction of separation. These first and second tip portions 73 and 74 can limit the relative coaxial rotation by accommodating the insertion shape portion 75 in the slide groove 79 without the need for the stopper screw 25. . That is, the 1st, 2nd front-end | tip parts 73 and 74 are produced by the slide structure connected so that relative rotation is impossible.

The first tip 73 is formed so that the cylindrical built-in screw 80 has a coaxial posture and is relatively slidably accommodated between the opposed surfaces of the pair of insertion-shaped portions 75.
The first tip 73 is formed with a thread extending in the length direction with the female threaded portion 78 facing the insertion-shaped portion 75, and the built-in screw 80 is a male meshing with the female threaded portion 78. A screw portion 87 is formed on the outer peripheral surface. For this reason, the male screw portion 87 and the female screw portion 78 have a screw structure that is connected by facing each other and meshing with each other.
The built-in screw 80 has an orthogonal member 81 passing through the axial center of the inner peripheral surface of the cylindrical space 76 of the second tip portion 74 that does not overlap the axial center, and is installed at both ends. It is rotatably supported by a rotating shaft 82 provided so as to coincide with the shaft center.
The second tip 74 has an operation window (exposure window) 85 that exposes the cylindrical space 76 to the outside by cutting out the outer peripheral surface adjacent to the slide groove 79. From the operation window 85, A male screw portion 87 on the outer peripheral surface of the built-in screw 80 protruding from the slit formed between the insertion shape portions 75 on the first tip portion 73 side is exposed to be rotatable.
As a result, the first tip 73 can be adjusted by rotating the built-in screw 80 exposed from the operation window 85 of the second tip 74 in the forward and reverse directions, and engaging the female screw 87 with the female screw 87. The meshing position with the screw portion 78 can be slid in the length direction, and the distance between the first and second projecting bars 21 and 22 can be adjusted.

  Therefore, in the Wilki 70, the first projecting rod 21 (the first distal end portion 73) is moved to the second projecting portion only by rotating the built-in screw 80 that is operably exposed at the second distal end portion 74 on the distal end side of the operation rod 11. By moving the rod 22 (second tip portion 74) in the length direction, the distance between the bars 22 can be adjusted to be positioned at the corners of the ring-shaped handle H or the spoke S to be worked.

  As described above, in the present embodiment, as in the third embodiment, the built-in screw 80 is directly rotated without rotating the first and second projecting bars 21 and 22 at the tip of the operation bar 11. The distance between the ring-shaped handles H can be adjusted so that the rotation of the ring-shaped handle H can be easily performed, and there is no need to prepare a plurality of types of wilches for each size of the ring-shaped handle H. Furthermore, it has a structure in which the tip portion does not easily fall off, and the safety of work can be improved. Therefore, it is possible to provide the wiki 10 that is highly versatile, easy to adjust, and safer.
