  By the way, some handles, such as a knot filter of an oil container in a steam turbine facility, have a T-shape. That is, it has a T-shaped and horizontally extending grip portion (T-shaped horizontal portion) and a vertically extending rotating shaft portion (T-shaped vertical portion). When the gripping portion is gripped and rotated, the rotating shaft portion is By rotating, a Knoh filter or the like connected to the rotating shaft portion rotates. When trying to rotate such a T-shaped handle with a rotating tool as described in Patent Document 1, the force is not properly transmitted to the T-shaped handle, and the rotating tool comes off the T-shaped handle. There is a case. That is, since the grip portion of the T-shaped handle is linear, the grip portion cannot be properly (reliably) clamped by the fixed leg and the movable leg, which are the two clamp members of the rotary tool. And even if the operating rod is turned in such an unstable clamping state, the force is not properly transmitted to the T-shaped handle, and the rotating tool is detached from the T-shaped handle.

  Then, an object of this invention is to provide the rotary tool for T-shaped handles which can rotate a T-shaped handle stably.

To achieve the above object, the invention according to claim 1 is a T-shaped handle rotation for rotating a T-shaped handle having a T-shaped horizontally extending gripping portion and a vertically extending rotating shaft portion. a tool, comprising a pincer attached to the operating rod of the rod-like, the clamping jig is al provided four ends of the cross section formed in a cross shape, with respect to the cross section and the control rod has Kyojiashi of round bar extending substantially perpendicularly Te, each Kyojiashi is disposed so as Kakoeru the central portion of the grip portion from four sides located above the rotating shaft of the T-shaped handle , Located at each apex angle of a substantially square in the cross portion, and the length reaches the central portion of the rotating shaft portion, and the operating rod is formed by two opposing pairs of sandwiching legs for sandwiching the grip portion. Arranged at one end and attached to the center of the cross A T-shaped rotating tool handle, characterized in that.

Is properly transmitted to the T-shaped handle. In addition, since the gripping portion is securely clamped, the T-shaped handle can be stably rotated without the gripping leg being detached from the gripping portion and the rotating tool from the T-shaped handle. As a result, the T-shaped handle can be easily and reliably rotated using the principle of the lever by the operating rod, and the safety of the work is improved because the rotating tool does not come off from the T-shaped handle. To do.

According to the first aspect of the invention, since the four holding legs surround the four sides of the center part of the holding part of the T-shaped handle, the holding part is more securely and firmly held by the holding legs. Is transmitted to the T-shaped handle more appropriately. In addition, since the central portion of the gripping portion is securely clamped, it is possible to further prevent the clamping legs from coming off the gripping portion.
Further, since the four clamping legs are positioned at the apex angles of the substantially square, that is, the intervals between the four clamping legs are substantially equal, the grip portion of the T-shaped handle is almost evenly divided by the four clamping legs. The force from the operating rod is more appropriately transmitted to the T-shaped handle. In addition, since the operating rod is disposed on substantially the center line of the substantially square shape formed by the four sandwiching legs, the sandwiching space that is the space between the sandwiching legs where the grip portion of the T-shaped handle is located is It is located on the extended straight line of the operation rod and in the direction orthogonal to the operation rod. For this reason, it becomes easy to position the holding space between the holding legs at the holding part of the T-shaped handle, and to hold the holding part between the two pairs of holding legs, thereby improving workability.

According to the invention described in claim 2 , since the four clamping legs are detachable, for example, a plurality of types of clamping legs are prepared in accordance with the size of the T-shaped handle, and the size of the T-shaped handle is determined. It is possible to handle a plurality of types of T-shaped handles having different sizes by attaching a gripping leg suitable for the above to the operating rod.

  Hereinafter, the present invention will be described based on the illustrated embodiments.

(Embodiment 1)
FIG. 1 is a front view (a) and a side view (b) of a rotary tool 1 for a T-shaped handle according to this embodiment. As will be described later, the T-shaped rotating tool for a handle 1 is a T-shaped rod-shaped gripping portion 101a (T-shaped horizontal portion) that extends horizontally and a rod-shaped rotating shaft portion 101b (T-shaped vertical portion) that extends vertically. A rotary tool for rotating a T-shaped handle 101 (T-shaped valve) having a control portion 2 and mainly includes an operating rod 2 and four clamping legs 3b.

  The operating rod 2 is made of a rod-shaped steel material, and a clamping tool 3 is attached to one end thereof. This clamping tool 3 is made of a rod-shaped steel material, and has a cross (X-shaped) cross 3a having substantially the same length in the vertical and horizontal directions, and the cross 3a from the four ends of the cross 3a. And sandwiching legs 3b extending substantially vertically. Each of the holding legs 3b of such a holding tool 3 is positioned at each apex of a substantially square (somewhat rectangular), and the operation rod 2 is positioned on the extended straight line of the center line of the substantially square. A clamping tool 3 is attached to one end of the 2. That is, the cross 3a is arranged in an X shape so that each sandwiching leg 3b is positioned at each apex angle of a substantially regular quadrangle, and the operation rod is placed on the straight line of the vertical center line of the cross 3a (X). 2 is disposed, and one end portion of the operating rod 2 and the center portion (cross portion) of the cross portion 3a are welded. As a result, the four clamping legs 3b extend substantially perpendicular to the operating rod 2, and the clamping space between the clamping legs 3b where the gripping portion 101a of the T-shaped handle 101 is located is an extended straight line of the operating rod 2. Located above (coaxial) and in a direction perpendicular to the operating rod 2. That is, two opposing pairs of sandwiching legs 3b are disposed so as to sandwich the grip portion 101a in the coaxial direction and the orthogonal direction of the operating rod 2.

  Further, as will be described later, the four sandwiching legs 3b are arranged so as to surround the four sides of the center portion 101c (rotation center portion) of the grip portion 101a located above the rotation shaft portion 101b of the T-shaped handle 101. It is installed. That is, according to the size of the T-shaped handle 101, the center portion 101c of the T-shaped handle 101 enters the sandwiching space that is the space between the sandwiching legs 3b, and the gap between the sandwiching leg 3b and the center portion 101c is large. The distances (intervals) D1 and D2 between the sandwiching legs 3b are set so as not to fall (so as to surround the four sides of the central portion 101c). Further, the length H of the sandwiching leg 3b is set so that the sandwiching leg 3b reaches the center of the rotating shaft 101b in a state where the four sandwiching legs 3b surround the four sides of the center part 101c. As a result, the sandwiching leg 3b is not easily detached from the grip portion 101a.

  On the other hand, an elliptical ring-shaped suspension ring 2a is formed at the other end of the operation rod 2, and is hung on a hook or the like of a tool place. The total length L of the rotary tool 1 for the T-shaped handle is T-shaped so that the force (torque) required to rotate the T-shaped handle 101 can be sufficiently generated using the principle of the lever by the operating rod 2. It is set according to the mold handle 101. Similarly, the diameter Φ1 of the operation rod 2 and the diameter Φ2 of the holding tool 3 are set so as to obtain a strength (bending rigidity, etc.) that can sufficiently withstand the force required to rotate the T-shaped handle 101.

  Next, the operation of the T-shaped handle rotating tool 1 having such a configuration will be described. Here, in this embodiment, the T-shaped handle 101 connected to the Knoh filter 102 of the oil device 100 as shown in FIG. The case where it rotates using the tool 1 is demonstrated.
