Description

  The present invention relates to a Wilky used for operating a ring-shaped handle ring.

  In facilities such as power plants, there are operations for manually opening and closing valves provided in various instruments and pipes for transferring liquids such as water (steam) and oil. In the operation of opening and closing the valve, a ring-shaped handle interlocking with the opening and closing of the valve is rotated. When the rotation resistance of the handle (valve) is large and it is difficult to open and close by human power, the handle is rotated using a handle operating tool called a Wilky.

  If an inappropriate Wilky key that does not match the size of the handle to be operated is used, the handle (valve) may be damaged or the Wilky may be damaged. For this reason, in facilities such as power plants, a plurality of types of Wilkies are prepared in accordance with the size of the handle to be operated.

  When the handle is operated, a Wilky having a size corresponding to the size of the handle to be operated is used. On the other hand, if a plurality of Wilkies are carried in accordance with the size of the handle to be operated on the site where the operation is performed using the Wilkies, it is heavy and the work efficiency is lowered. In addition, it is not realistic from the viewpoint of storage location and cost to prepare Wilky for each worker to use for each number of workers. In situations where a limited number of Wilkies are shared by a certain worker, If another worker takes out the Wilky to be used, the work is interrupted and the work efficiency is lowered.

  Specifically, as a technique related to such a Wilky key, for example, conventionally, for example, two fixed legs extended from the operating rod, and slidably mounted along the operating rod, are advanced with respect to the fixed leg. Further, there has been a technique related to a Wilky that is provided with a movable leg that can be retracted, and the fixed leg and the movable leg have a divergent shape that spreads outward from an operating rod (for example, see Patent Document 1 below).

  Specifically, for example, conventionally, for example, a pair of holding legs composed of two holding legs extending substantially in the same direction as the axial direction of the operating rod is attached to the end of the rod-shaped operating rod. There has been a technique related to Wilkie in which a plurality of radial pairs are provided around the axis and the distance between the holding legs of each holding leg pair is different (see, for example, Patent Document 2 below).

  More specifically, conventionally, for example, a Wilky in which a plurality of fixed leg pairs each having a different interval between a pair of fixed legs perpendicular to the axis of the operating rod are provided at different positions in the axial direction of the operating rod. There was a technique (see, for example, Patent Document 3 below).

  However, the conventional technique described in Patent Document 1 described above is difficult to apply to the valve when operating a valve that requires a large force to rotate, such as a large valve, and is practical. There was a problem of being inferior.

  In addition, the conventional techniques described in Patent Document 2 and Patent Document 3 described above are applicable to limited valve sizes. Therefore, the size of the valve to be operated is grasped in advance, and the valve to be operated is selected. There was a problem that it was troublesome to carry several Wilkies according to the size. As described above, each of the conventional techniques described above has a problem that it is inferior in versatility and insufficient for practical use.

The screw hole 101 a penetrates the flange member 101 along the axial direction of the pair of leg members 102 and 103, that is, the direction orthogonal to the axial direction of the flange member 101.

  On the inner peripheral surface of the screw hole 101a, a screw thread having the same pitch as that of the screw thread 102a provided in one leg member 102 is provided. The protruding amount of the one leg member 102 from the flange member 101 can be adjusted by adjusting the screwing amount of the screw thread 102a with respect to the screw hole 101a. The screwing amount of the screw thread 102a with respect to the screw hole 101a can be adjusted steplessly.

  The other leg member (second leg member) 103 of the pair of leg members 102 and 103 is connected to the flange member 101 via the slide member 201. The slide member 201 includes a support portion 202 that supports the other leg member 103 and a rack portion 203 having a rack shape.

  On the outer peripheral surface of the other leg member 103, a screw thread (male screw) 103a is provided on one end side. The other leg member 103 is coupled to the slide member 201 by screwing a screw thread 103a provided on one end side into a screw hole (female screw) 104 provided in the support portion 202 of the slide member 201. Yes.

  The screw hole 104 penetrates the support portion 202 in the slide member 201 along a direction orthogonal to the axial direction of the other leg member 103, that is, the axial direction of the flange member 101. The protruding amount of the other leg member 103 from the flange member 101 can be adjusted by adjusting the screwing amount of the screw thread 103 a with respect to the screw hole 104. The screwing amount of the screw thread 103a with respect to the screw hole 104 can be adjusted steplessly.

  The slide member 201 is slidably connected to the flange member 101 along the axial direction of the flange member 101. Specifically, the rack portion 203 in the slide member 201 is inserted into a groove 204 provided in the flange member 101 and having the longitudinal direction of the flange member 101 as a longitudinal direction. It can slide along the axial direction of the member 101.

  The flange member 101 is provided with a slit 105 that penetrates the flange member 101 along the extending direction of the other leg member 103.
