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. Also, if the rotational resistance of the rotating shaft has increased due to rust, oil and fat adhesion, etc., it may take a great deal of force to rotate the handle manually, and it is judged that the valve has been completely tightened. Nevertheless, there is a case where the fluid continues to leak because it has not actually been tightened. 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, since 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, the biting teeth are likely to slip in the rotating direction when the handle is rotated, and the operability is poor. Moreover, it is dangerous.
An F-shaped Wilky may be used instead of the pipe wrench, but it has the same drawbacks as the pipe wrench.

  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 operation 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 in order to provide 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).

Further, the conventional Wilky as described above is suitable for the operation of a relatively large-diameter handle, but is not suitable for the operation of a small-diameter handle suitable for holding and rotating with the palm of one human hand. In particular, the Wilkey as described above is difficult to adjust the force because it grips the operating rod and rotates the handle, and when applied to a small-diameter handle operation, by applying excessive force to the handle shaft or the valve itself There was a risk of damage.
Japanese Utility Model Publication No. 6-17874

As described above, the conventional handle key is not suitable for carrying because it has a long operation rod, and it is difficult to operate in places where there is no space around the handle. There is a problem that it is not suitable for the operation of a small-diameter handle that is gripped and operated.
The present invention has been made in view of the above, and can be applied not only to a small-diameter handle suitable for being gripped and operated by the palm of one hand, but also to facilitate the rotation of the handle by manual operation. Operable regardless of the presence or absence of obstacles around the handle, and it is more portable due to its small size and light weight. It aims to provide Wilkie for use.
Furthermore, the present invention provides a handle operating wheelie that can sufficiently adjust the force by not using an operating rod even when a handle having a large diameter that cannot be grasped with one hand is operated. For other purposes.

In order to achieve the above object, the invention of claim 1 is a Wilky for rotating a handle provided with a ring-shaped portion fixed via a rib to a rotating shaft, and has a larger diameter than the ring-shaped portion. A plurality of fittings projecting from the gripping portion and the front surface of the gripping portion corresponding to the engaging portion formed between the rib and the ring-shaped portion, at positions that can be fitted in the engaging portion. And a mating protrusion.
If the handle for opening and closing the valve has a small diameter, or if the valve opening and closing mechanism is fragile, it may be impossible to operate with a conventional pipe wrench or F-shaped Wilky, or excessive force There was a risk of destroying the handle and valve by adding. In the Wilky of the present invention, it is possible to perform an operation while adjusting the force by directly gripping the grip portion attached to the upper surface of the ring-shaped portion with one hand or both hands without relying on the operation rod. For this reason, there is no possibility that the handle side will be damaged or the valve will not close properly due to poor tightening. In terms of configuration, since it has a simple structure consisting of a gripping portion and a fitting protrusion, the strength and durability are increased, and the cost is lower than that of a conventional Wilky or the like.

According to a second aspect of the present invention, in the first aspect, the fitting protrusion is detachably supported by a support hole provided in the grip portion.
If the fitting protrusion is fixed, it can only be applied to a handle of a specific shape and size. However, if the position, number, and shape of the fitting protrusion can be changed in various ways, a handle with various forms (ring shape) Part).

According to a third aspect of the present invention, in the second aspect of the present invention, the fitting projection is configured such that a circumferential position and / or a radial position can be changed by the support hole.
The position where the fitting protrusion is arranged can be arbitrarily changed by devising various shapes of the support hole.

The invention of claim 4 is characterized in that, in claim 2 or 3, the support hole is a long hole extending in the circumferential direction.
By employing a long hole extending in the circumferential direction as the support hole, various positions in the circumferential direction of the fitting protrusion can be selected.

According to a fifth aspect of the present invention, in the second, third, or fourth aspect, the support hole is a long hole extending in a radial direction.
By adopting a long hole extending in the radial direction as the support hole, various radial positions of the fitting protrusions can be selected.

The invention of claim 6 is characterized in that, in claim 2, the support hole is a cross-shaped elongated hole.
By providing the cross-shaped long hole, the circumferential direction and radial position of the fitting protrusion can be changed and set by one long hole.

A seventh aspect of the invention is characterized in that, in any one of the first to sixth aspects, a small handle protrudes from the grip portion.
When the handle is rotated using the Will key of the present invention, when it is difficult to rotate the handle only by using the grip portion, a strong force can be output by using the small handle.

According to the present invention, since the grip portion is directly assembled to the ring-shaped portion, the handle rotation operation by manual operation is applied to a handle having a small diameter suitable for gripping and operating the palm of one hand, for example. It is easy to operate, regardless of the presence or absence of obstacles around the handle, it is easy to operate because it is small and lightweight, and it is easy to carry. Will not be damaged.
Furthermore, even when a handle having a large diameter that cannot be grasped with one hand is operated, the force adjustment can be sufficiently adjusted by not using the operating rod.

Thus, the Wilky of the present invention can be applied to a handle (ring-shaped portion) having various diameter sizes and various engaging portions (holes, recesses), thereby facilitating manual rotation of the handle. In addition, it is possible to provide a handle-use Wilky that is excellent in operability regardless of the presence or absence of obstacles around the handle, and is excellent in portability because of its small size and light weight.
The mounting position, the number, etc. of the fitting protrusions can be arbitrarily adjusted.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
FIGS. 1A, 1B, and 1C are explanatory views showing a procedure for attaching and operating a wheel key for handle operation according to an embodiment of the present invention to the handle, and FIGS. 2A and 2B. These are the front view and top view which show the structure of this Wilky.
