Description

  The present invention relates to an improvement in a handle operating wheelie suitable for manually and reliably rotating a handle for manually opening and closing various valves and the like installed in a power plant, factory, and the like.

Tanks for storing fluids such as various liquids such as water, oil and fuel, various gases such as gas and steam, etc., to transfer these fluids to various facilities such as power plants and manufacturing plants Pipes are provided at appropriate locations on tanks and pipes to adjust the amount of fluid flowing into and out of the tank, adjustment of the transfer amount and pressure of the pipes, switching of the transfer direction, etc. It is comprised so that it can perform.
When the valve is opened and closed by manual operation, the center portion of the ring-shaped handle is often fixed to the rotating shaft connected to the valve shaft, and the handle is often rotated by hand.

  However, for example, there are various types of handles installed in hydroelectric power plants, from types having a small diameter to those having a large diameter. In addition, if the rotational resistance of the rotating shaft is increased, it may take a great deal of force to rotate the handle manually, so that the tightening is actually finished even though it is determined that the valve is completely tightened. In some cases, the fluid may continue to leak due to failure. For example, since the opening / closing mechanism of the oil discharge valve of the hydraulic device is heavy and hard, it is assumed that the valve cannot be completely closed by a manual handle operation, and the hydraulic pressure in the hydraulic tank decreases.

  In order to cope with such a problem, the handle is often rotated using a pipe wrench installed on the site. When working with a pipe wrench, a method of rotating the handle by biting the bite of the pipe wrench into the ring of the handle is generally adopted. However, the pipe wrench is excessive in size and weight and is suitable for carrying. Therefore, it has been extremely difficult to carry a pipe wrench and move the hydroelectric power station in order to sequentially operate a large number of valves. In addition, the pipe wrench may become unusable depending on the installation status of the handle, particularly the operation space around the handle. Furthermore, the biting teeth of the pipe wrench are structured to bite on the handle surface perpendicular to the direction in which the handle is rotated. Moreover, it is dangerous.

  In Patent Document 1, two fixed legs bifurcated at the tip of a linear rod-shaped operating rod and a movable leg supported so as to be slidable along the operating rod are provided. In addition, a handle wheelie is disclosed in which an operating rod is gripped to rotate the handle by engaging the movable leg with another part of the handle while engaging with the outside. This Wilky has the advantage that it can be used in common for handles of different diameter sizes. Further, since the fixed leg and the movable leg are inserted and fixed inside the ring-shaped part, slip does not occur in the direction in which the handle is rotated.

However, assuming that this Wilky is applied to a large-diameter handle, the total length of the operating rod needs to be a dimension that includes the diameter of the large-diameter handle and the length of the grip for the operator to grip. Therefore, it becomes long, large, and heavy, and it is difficult to store it in a pocket of work clothes. In addition, the overall length of the operating rod must be long to give versatility to handle handles of various diameters, so if there are obstacles around the handle, it can be assembled to the handle. It is also assumed that it is impossible to rotate. Furthermore, while the length of each fixed leg bifurcated and the opening leg angle are fixed, it is necessary to assemble the fixed leg and the movable leg to the handle with the rotating shaft located at the center of the handle in between. Therefore, there may be cases where the handle cannot be used depending on the size and shape of the handle (particularly, the shape and number of ribs extending radially from the rotating shaft and connected to the ring-shaped portion).
Japanese Utility Model Publication No. 6-17874

As described above, the conventional wheel key for operating the handle has a drawback in that when the handle to be rotated has a large diameter, it has to be large and heavy. Moreover, the situation which cannot be applied according to the shape, size, etc. of the rib which comprises a handle | steering-wheel was assumed.
The present invention has been made in view of the above, and can be applied to a handle having various diameter sizes to facilitate the rotating operation of the handle by manual operation, as well as whether there is an obstacle around the handle. It is an object of the present invention to provide a handle-use Wilky that has good operability regardless of the size, and is excellent in portability due to its small size and light weight.

In order to achieve the above object, the invention according to claim 1 is a Wilky key for rotating a handle having a ring-shaped portion fixed to a rotating shaft via a rib. An engagement member attached to the flange, the engagement member being rotatably supported by the inner contact member that contacts the inner portion of the ring member, and the outer peripheral surface of the inner surface An outer abutting member opposed to the abutting surface of the abutting member, and the distance between the rotation center of the outer abutting member and each part of the outer peripheral surface is not constant.
According to a second aspect of the present invention, in the first aspect, a gear portion is provided on the outer periphery of the outer abutting member.
The invention of claim 3 is characterized in that, in claim 1 or 2, the operating rod is configured to be extendable.

  According to the present invention, an operating rod and an engaging member attached to the operating rod are provided. The engaging member includes an outer abutting member that abuts on the outer peripheral portion of the ring-shaped portion of the handle, and the ring-shaped portion. An inner abutting member that abuts the inner peripheral portion, and the inner abutting member abuts against the rib of the handle simultaneously with the inner peripheral portion of the ring-shaped portion, thereby interposing the ring-shaped portion with the outer abutting member. Since it is configured to hold the pinch, it can be applied to handles with various diameter sizes, facilitating manual rotation of the handle, regardless of the presence of obstacles around the handle. It is possible to provide a handle-use Wilky that has good operability, and is excellent in portability due to its small size and light weight.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
FIG. 1A and FIG. 1B are a perspective view showing a configuration of a wheelie for handle operation according to an embodiment of the present invention and an explanatory view showing a use state.
The Wilky 1 is means for manually rotating a handle 50 including a ring-shaped portion 53 that is fixed via a rib 52 to a rotating shaft 51 as an operation target.
The Wilky 1 is generally composed of an operating rod 2 having a grip portion 2a that can be gripped at one end, and an engaging member 5 that is integrally attached to the other end of the operating rod 2, and has sufficient rigidity. And is made of a metal material.

The engaging member 5 includes an outer contact member 6 that contacts the outer peripheral portion (outer peripheral surface) 53 a of the ring-shaped portion 53 and an inner contact member 7 that contacts the inner peripheral portion (inner peripheral surface) 53 b of the ring-shaped portion 53. And. The outer abutting member 6 includes an upper outer abutting member 6a and a lower outer abutting member 6b that protrude in the vertical direction with the support member 10 positioned on the extension of the operating rod 2 interposed therebetween. The inner abutting member 7 includes cylindrical inner abutting members 7 a and 7 b that project from the upper and lower surfaces along the front edge of the support member 10. The formation positions of the inner abutting members 7a and 7b are not aligned with each other and are shifted from each other at the both end corners of the front end edge of the support member 10. In particular, the inner contact members 7a and 7b are located outside the both end edges of the contact surfaces 6a 'and 6b' of the outer contact member.
The support member 10 constitutes a part of the operation rod 2.
The shape of each contact surface 6a ′, 6b ′ of the outer contact member 6 may be a flat surface as shown in the figure, or may be formed in a jagged shape to increase the frictional resistance. The inner abutting member 7 does not have to be cylindrical, and may have a polygonal columnar shape or any other shape, or a process for increasing the frictional resistance may be applied to the outer peripheral surface.

  When the Wilky 1 of the present invention is attached to the handle 50 and rotated, first, as shown in FIG. 1B, the inner contact member 7a is inserted inside the ring-shaped portion 53 of the handle 50, and the outer contact is made. By positioning the member 6a outside the ring-shaped portion 53, a part of the ring-shaped portion 3 is sandwiched between the inner contact member 7a and the outer contact member 6a. At this time, the inner contact member 7 a is brought into contact with one side surface 52 a of the rib 52. In this state, the grip 2a of the operating rod 2 is gripped and rotated in the direction indicated by the arrow in FIG. When rotating in the reverse direction, the lower inner contact member 7b is inserted into the ring-shaped portion 53 so as to contact the opposite side surface 52b of the rib 52, and the inner contact member 7b and the outer contact member are inserted. The ring-shaped portion 53 is sandwiched between 6b and the grip 2a is gripped and rotated in the reverse direction.

In the present invention, the formation positions of the inner contact members 7a and 7b are displaced outward from the left and right edges of the contact surfaces 6a ′ and 6b ′ of the corresponding outer contact members. The distance L1 between the contact members 7a and 7b and the contact surfaces 6a ′ and 6b ′ of the corresponding outer contact members is set to be a line obtained by extending the contact surfaces 6a ′ and 6b ′ and the inner contact members 7a. , 7b can be made longer than the distance L2. For this reason, the ring-shaped part 53 having a thickness T that can enter the distance L1 can be received and rotated. Therefore, the handle 50 having the ring-shaped portion 53 having the thickness T smaller than the distance L1 can be engaged and rotated.
With the inner contact member 7 in contact with the side surface of the rib 52, the operating rod 2 is pressed in a predetermined rotation direction, so that the engagement member 5 does not slip in the rotation direction of the handle. Moreover, since the engaging member 5 only engages with one portion of the ring-shaped portion 53 of the handle, it is firmly engaged with the handle without being affected by the overall diameter of the handle, the number of ribs, and the like. be able to. In addition, since the length of the operation rod 2 can be shortened, not only the influence of obstacles around the handle can be minimized, but also the jig can be reduced in size and weight so that it has excellent portability. Can be used as

FIG. 2 shows a modified example, and this Wilky 1 is a type in which the inner contact member 7 and the outer contact member 6 are provided only on one side of the support member 10. This single-sided Wilky can be used by turning the handle upside down by turning it upside down.
As shown in FIG. 2, the operation rod 2 can be expanded and contracted in the axial direction by, for example, a multistage expansion structure, so that the operation can be performed in a state where the engagement member 5 is engaged with the ring-shaped portion 53. The force required to press the heel 2 in the rotational direction can be adjusted. That is, when the load on the rotating shaft of the handle is large and a strong force is required, an efficient operation can be performed by extending the operating rod and pressing it in the rotating direction. Therefore, there is no problem that the valve is incompletely tightened or opened due to incomplete operation of the handle.
In the above embodiment, since the distance L1 between the outer contact member 6 and the inner contact member 7 is constant, it is difficult to apply to a handle having a ring-shaped portion 53 having a thickness T exceeding the distance L1. . In order to solve this problem, the distance L1 between the outer contact member 6 and the inner contact member 7 may be configured to be variable.

FIG. 3 is a perspective view according to a configuration example for making the position of the outer contact member variable. This Wilky 1 has a long hole 15 penetrating from one side of the operation rod 2 to the other side, and a bolt portion 16 provided on the outer abutting member 6 is inserted into the long hole 15 from the other side of the long hole 15. Fastening means 16a such as a wing nut is fastened to the tip of the projecting bolt portion so that the outer abutting member 6 can be fixed at an arbitrary position on the operating rod 2. Instead of the long holes 15, round holes into which the bolt portions 16 can be inserted may be arranged in the longitudinal direction of the operating rod at a predetermined pitch.
As described above, the position of the outer abutting member 6 on the operating rod is variably configured, and the distance L1 between the inner abutting member 7 is variably configured. The engagement member 5 can be firmly fixed to the ring-shaped portion while flexibly handling the handle, and the handle can be rotated with good operability.
In addition, you may comprise so that the position on the supporting member 10 of an outer side abutting member may be adjusted by providing the above slits and a round hole on the supporting member 10. FIG.
