Description

  In this invention, when manually opening and closing various valves and other equipment or equipment installed in a power plant, factory, etc., a rotating body such as a handle for opening and closing the equipment or equipment is simply and reliably rotated. And a method of forming a means for preventing slipping off of the rotating body when the tool for rotating operation is attached to the rotating body and assembled.

The applicant of the present application has filed a patent application for the invention disclosed in Patent Document 1 regarding the Wilky that is difficult to remove from the handle of the manual valve, and the invention relating to this patent application has already been publicly disclosed.
The construction of this Wilky will be briefly described. It has a long rod-like operation rod provided with a hooking portion composed of a first arm and a second arm for hooking an annular rim of the handle on one end side. However, the first arm and the second arm extend in a direction substantially perpendicular to the axial direction of the operating rod to form a substantially F shape, and the cross section thereof is not a circular shape, but the axis of the arm. The contact area that contacts the annular rim of the handle is expanded by making it a substantially semicircular shape by cutting out along the direction.

In addition, the applicant of the present application has filed a patent application for the invention disclosed in Patent Document 2 as a Wilky that is difficult to be detached from the valve handle during operation, and the invention related to this patent application has also been published and has become publicly known. ing.
When the construction of this Wilky is outlined, it has a plurality of engaging protrusions extending in a substantially right angle direction with respect to a long rod-shaped operating rod. These engaging protrusions are described in paragraph number “0033” of this Patent Document 2. As shown in the figure, a rubber layer (synonymous with the rubber layer of the present application; hereinafter the same) is provided over the entire circumferential surface.

  However, when the handle is rotated by the Wilky hook by hooking it to the joint between the spoke and rib of the handle, when the handle is rotated in the valve opening direction, the Wilky is hooked on the left side of the spoke and the handle is moved. When rotating the valve in the closing direction, the Wilky is hooked to the right side of the spoke. In order for force to be efficiently transmitted from the Wilky to the handle, the handle is rotated in the valve opening direction and the handle. It is necessary to make the angle of the contact surface different when rotating the valve in the valve closing direction. For this reason, it is necessary to prepare two types of Wilkie, a Wilky for rotating the handle in the valve opening direction and a Wilky for rotating the handle in the valve closing direction. Moreover, the existing Wilkie cannot be used as it is because notches are formed in each Wilkie.

  In addition, the rotation operation of the handle by the Wilky key is not only the contact between the two opposing surfaces of the two arms and the handle, but also the handle between the arms of the control rod and the handle does not contact the handle from the Wilky to the handle. Since it is considered that the force for rotation is not easily transmitted, the Wilkie described in Patent Document 2 has a configuration in which the rubber layer is formed only on the entire peripheral surface of the engagement protrusion corresponding to the arm. It is not enough as an anti-slip means for Wilkie.

  And in the Wilkie shown by patent document 2, the method of forming the rubber layer described in the said patent document 2 in the perimeter surface of an engaging protrusion is not disclosed.

  On the other hand, as a Wilky material, an expensive metal such as a beryllium copper alloy may be used in order to prevent the occurrence of sparks due to collision with other objects due to falling.

  Therefore, the present invention considers the actual operation of rotating a handle by a general Wilky, and can reliably prevent slipping off from the handle at a relatively low cost. An object of the present invention is to provide a rotating body operating tool provided with a non-slip means capable of preventing the occurrence of sparks due to a collision of the rotor and a method of forming the anti-slip means on the rotating body operating tool.

  A rotating body operating tool according to the present invention is for rotating a rotating body for manually opening and closing an opening / closing means of equipment or equipment, and comprises a long rod-shaped operating rod, and this operating rod. A hook portion for gripping the rotating body, which is provided on one end side in the longitudinal direction, and the hook portion extends from the operating rod, and the base portion. A first arm and a second arm extending in parallel from the portion along the radial direction of the base portion, and at least the surfaces of the first arm and the second arm face each other. And a range having a possibility of coming into contact with the rotating body, and a possibility of coming into contact with the rotating body from the base end of the first arm to the base end of the second arm in the surface of the base portion. Anti-slip means are formed for the range It is characterized in that (claim 1). Here, the opening / closing means of equipment or equipment refers to various valves (valves) installed in, for example, a power plant or factory. The rotating body refers to a handle for opening and closing various valves, for example.

  Thereby, about the hook part of the rotating body operation tool, not only the range having the possibility of facing each other and contacting the rotating body among the surfaces of the first arm and the second arm of the rotating body operation tool. Since the surface of the base portion extending from the operating rod extends from the base end of the first arm to the base end of the second arm, the anti-slip means is also formed in a range where there is a possibility of coming into contact with the rotating body. When the rotating body operating tool is hooked onto the rotating body and assembled and the rotating body is manually rotated, it is possible to more reliably prevent the rotating body operating tool from slipping off the rotating body. In addition, since the existing rotating body operating tool can be used as it is as the base of the present invention, it is possible to suppress an increase in cost in manufacturing as a rotating body operating tool with anti-slip means.

  In particular, the rotating body operating tool according to claim 2 is characterized in that the hooking portion is formed with anti-slip means over the entire surface of the first and second arms and the base portion.

  As a result, when the anti-slip means is formed on the rotating body operating tool, the range of formation of the anti-slip means on the hooking portion is selected from the surface of the first arm and the surface of the second arm of the rotating body operating tool. A range that has a possibility of being opposed to each other and abutting the rotating body, and a surface of the base portion that extends from the base end of the first arm to the base end of the second arm and has a possibility of contacting the rotating body. By not being limited to the range, the anti-slip means can be formed more easily and inexpensively with respect to the rotating body operating tool.

  In particular, the rotating body operating tool according to claim 3 is characterized in that non-slip means is formed in the entire range of the hook portion and the operating rod. In this case, it is more preferable that the non-slip means is a rubber layer formed by thinly covering the surfaces of the first and second arms and the base portion.

  As a result, the rotating body operating tool is provided with anti-slip means in the entire range of the hook portion and the operating rod. Moreover, since the anti-slip means is a rubber layer, the rotating body operating tool can be removed by dropping. Even if it collides with other things, no sparks are produced.

  The method of forming the anti-slip means on the rotating body operating tool according to the present invention is used for rotating the rotating body for manually opening and closing the opening / closing means of equipment or equipment, And a hook portion for gripping the rotating body provided on one end side in the longitudinal direction of the operation rod. Anti-slip means is formed for a rotating body operating tool comprising an extended base portion and a first arm and a second arm extending in parallel from the base portion along the radial direction of the base portion. The method is to immerse the rubber solution in a rubber solution tank in which a rubber solution is stored, so that at least the entire range of the first and second arms and the proximal end of the first arm of the base portion are the second. The entire range extending to the proximal end of the arm Surface is coated with a thin rubber layer, is characterized in that anti-slip means are formed (claim 5). In this case, when a rubber layer is formed in the entire range of the hook of the rotating body operating tool and the operating rod, so-called submersion is performed in which all of the so-called rotating body operating tool is immersed in the rubber solution tank in which the rubber solution is stored. Is called.

  As described above, in the present invention, it is possible to form the anti-slip means on the existing rotating body operating tool by a simple method of immersing the rotating body operating tool in the rubber solution tank in which the rubber solution is stored.

As described above, according to the first to fourth aspects of the present invention, the hooking portion of the rotating body operating tool is a mutual contact between the surface of the first arm and the surface of the second arm of the rotating body operating tool. The surface of the base portion extending from the operating rod extends from the base end of the first arm to the base end of the second arm as well as the range having the possibility of contacting the rotary body and the rotary body. The anti-slip means is also formed in the range where there is a possibility of contact with the rotary body, so that when the rotary body operating tool is assembled by hooking the rotary body and the rotary body is operated manually, It can prevent more reliably that it slips off from a rotary body.
Moreover, according to the invention described in claims 1 to 4, since the existing rotating body operating tool can be used as it is as a base, an increase in cost in manufacturing as a rotating body operating tool with anti-slip means is also achieved. It is possible to suppress.

  In particular, according to the second aspect of the present invention, when the anti-slip means is formed in the hook portion of the rotating body operating tool, the formation range of the anti-slip means is defined by the surface of the first arm of the rotating body operating tool and The range of the surface of the second arm that faces each other and has the possibility of coming into contact with the rotating body, and the surface of the base portion extends from the base end of the first arm to the base end of the second arm and rotates. Since it is not limited to the range having the possibility of coming into contact with the body, the anti-slip means can be formed more easily and inexpensively with respect to the rotating body operating tool. It is possible to suppress an increase in cost when manufacturing as a working tool.

  In particular, according to the invention described in claim 3 and claim 4, the rotating body operating tool has the anti-slip means formed in the entire range of the hooking portion and the operating rod, and the anti-slip means is a rubber layer. Therefore, even if the rotating body operating tool collides with another object due to falling, no spark is generated. For the material of the rotating body operating tool, for example, beryllium copper alloy or the like for suppressing the occurrence of sparks due to the collision. It becomes unnecessary to use an expensive metal, and it is possible to adopt a normal metal such as iron. For this reason, since the raw material of the rotating body operating tool can be reduced, it is possible to suppress an increase in cost in manufacturing the rotating body operating tool with the non-slip means.

  In the invention according to claim 5, when adding the rubber layer to the hook portion of the rotating body operating tool, a simple method of immersing the rotating body operating tool in the rubber solution tank in which the rubber solution is stored is adopted. It is possible to suppress an increase in cost in manufacturing as a tool for operating a rotating body with attachment from the aspect of forming the anti-slip means. In addition, a technique called soaking can be used in which the entire rotating body operating tool is immersed in a rubber solution tank in which a bar solution is stored to form a rubber layer over the entire range of the rotating body operating tool.

It is.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 to 4 show an example of a rotating body operating tool 1 according to the present invention. This rotary body operating tool 1 is also called a Wilky, and is shown in FIG. 3 and has a plurality of annular rims 11 and a plurality of radial rims 11 extending radially from a hub 12 located at the center of the rim 11 to the rim 11 side. This is a tool for manually rotating the rotating body 10 such as a handle formed of the spoke 13.

  More specifically, in facilities such as thermal power plants, a large number of facilities or equipment (not shown) such as flow path opening / closing valves and shut-off valves are installed in piping systems of gases such as various liquids and steam. These valves are provided with a rotating body 10 shown in FIG. 3, and the valves can be opened and closed by manually rotating the rotating body 10. It is a tool used for the rotating body 10 for opening and closing such a valve.

  As shown in FIGS. 1 and 2, the rotating body operating tool 1 is provided on a long circular rod-like operating rod 2 and one end side in the longitudinal direction of the operating rod 2, and the rotating body The material for the rotating body operating tool 1 is generally used in this type of rotating body operating tool 1 such as a beryllium copper alloy. A metal may be used as it is, but a general metal material such as iron may be used in addition to the rubber layer 7 described later.

  As shown in FIGS. 1 and 2, the hook portion 3 of the rotating body operating tool 1 is a circular shape that extends from one side in the longitudinal direction of the operating rod 2 along the axis of the operating rod 2. The rod-like base portion 6, the circular rod-like arm 4 extending in the radial direction of the base portion 6 from the opposite end of the base portion 6 to the operating rod 2 side, and the operation of the arm 4 of the base portion 6 It is composed of a circular bar-shaped arm 5 extending from the side of the flange 2 in the radial direction of the base portion 6 and in parallel with the arm 4, and has a substantially F shape. In this embodiment, the arms 4 and 5 extend in a direction perpendicular to the base portion 6 and the axis of the base portion 6. Further, the distance between the arm 4 and the arm 5 has such a dimension that the rim 11 of the rotating body 10 can be sandwiched from an appropriate direction (for example, an oblique direction with respect to the radial direction of the rim 11). The protruding widths of the base portions 6 of 4 and 5 have a dimension sufficient to be pulled by the rim 11 and the spoke 13 of the rotating body 10.

  Thereby, for example, as shown in FIG. 3, with respect to the hook portion 3 of the rotating body operating tool 1, the side peripheral surface of the arm 4 is the inner peripheral side surface of the rim 11 of the rotating body 10 and the rotation direction of the spoke 13. The side surface of the arm 5 is in contact with the opposite side surface, the side surface of the arm 5 is in contact with the outer peripheral side surface of the rim 11 of the rotating body 10, and the lower side surface of the base portion 6 on the arm 4, 5 side is the rim of the rotating body 10. The valve connected to the rotating body 10 by assembling it at the connecting portion between the rim 11 and the spoke 13 of the rotating body 10 so as to contact the upper surface of the rotating body 10 and manually applying force in the direction of the arrow in FIG. (Not shown) can be performed.

  By the way, the rotating body operating tool 1 according to the present invention is covered with a thin film-like rubber layer 7 in the entire range, as particularly shown in FIGS.

  As a result, as shown in FIG. 3, when the hook 3 of the rotating body operating tool 1 is assembled to the connecting portion between the rim 11 and the spoke 13 of the rotating body 10, the rotating body 10 of the hook 3 contacts the rotating body 10. Since the rubber layer 7 that functions as the anti-slip means is formed on the rotating body operating tool 1 in the entire range, the range having the anti-slip means is relatively enlarged. When gripping the operating rod 2 of 1 and applying a force to the rotating body 10 from the hook 3, the hook 3 is more reliably prevented from slipping than when the arms 4 and 5 have anti-slip means only. can do.

  In addition, since the entire range of the rotating body operating tool 1 is covered with the rubber layer 7, even if the rotating body operating tool 1 falls and collides with other objects, the occurrence of sparks can be prevented. The degree of freedom of the material of the rotating body operating tool 1 is increased, and as a result, a relatively inexpensive metal such as iron can be used as the material.

  Next, an example of a method for forming the rubber layer 7 on the rotating body operating tool 1 will be described with reference to FIG. First, as shown in FIG. 4 (a), for example, the existing rotating body operating tool 1 including the operating rod 2 and the hooking portion 3 and the entire rotating body operating tool 1 can be submerged. After preparing the rubber solution tank 8 in which the rubber solution 9 is stored, as shown in FIG. 4 (b), the entire tool 1 for operating a rotating body is immersed in the rubber solution 9 in the rubber solution tank 8. As shown in FIG. 4 (c), the rotating body operating tool 1 is extracted from the rubber solution tank 8.

  In addition, in Example 1, although the range of the rubber layer 7 was demonstrated as the whole range of the rotary body operation tool 1, it is not necessarily limited to this. Hereinafter, modified examples of the range in which the rubber layer 7 is formed will be described as Example 2 and Example 3 in FIGS. 5 and 6, respectively. However, the same code | symbol is attached | subjected about the structure similar to the rotary body operation tool 1 demonstrated in Example 1 mentioned above, and the description is abbreviate | omitted.

  The rotating body operating tool 1 shown in FIG. 5 includes a range in which the surface of the arm 4 and the surface of the arm 5 face each other and can come into contact with the rotating body 10, and between the arms 4 and 5 in the surface of the base portion 6. The rubber layer 7 is formed only in a range where it can come into contact with the rotating body 10.

  Thereby, since the rubber layer 7 as the anti-slip means is provided in the entire range in which the hook portion 3 of the hook portion 3 of the rotary member operating tool 1 can come into contact with the rotor portion 10, the hook portion 3 slips off as in the first embodiment. As compared with the case where only the arms 4 and 5 have non-slip means, the amount of rubber used can be reduced, and the rotating body with the rubber layer 7 can be operated. It is possible to further reduce the cost for manufacturing the tool 1.

  The rotating body operating tool 1 shown in FIG. 6 has a thin film-like rubber layer 7 in the entire range of the arms 4 and 5 and the range of the base portion 6 from the base end side of the arm 4 to the base end side of the arm 5. It is covered. As shown in the first embodiment, the rubber layer 7 may be formed on the operating rod 2 side with respect to the arm 5 of the hook portion 3.

  For this reason, the third embodiment also has the rubber layer 7 as the anti-slip means in the entire range in which it can come into contact with the rotating body 10 of the hooking portion 3 of the rotating body operating tool 1. Further, it is possible to more reliably prevent the hook portion 3 from slipping out as compared with the case where only the arms 4 and 5 have anti-slip means. Further, the amount of rubber used can be reduced as compared with Example 1, and the method of forming the rubber layer 7 can be simplified as compared with Example 2. That is, in the rubber solution tank 8 shown in FIG. 4, only the hook portion 3 of the rotating body operating tool 1 is immersed in the entire range of the arms 4 and 5 and from the proximal end side of the arm 4 of the base portion 6 to the arm 5. The rubber layer 7 can be formed in a range up to the base end side.

  Moreover, since the center of gravity of the rotating body operating tool 1 is biased toward the hooking portion 3, the rotating body operating tool 1 often falls from the hooking portion 3 side when falling, but the hooking portion 3 is attached to the rubber layer 7. Since the spark is not generated even when the hook 3 collides with another object, the possibility that a spark is generated when the rotating body operating tool 1 falls and collides with another object is reduced. It is possible to make it.
