Description

TECHNICAL FIELD The present invention relates to a switch operation ring cover that is used by being attached to an operation ring attached to the end of an operation rope for turning on and off a switch installed on a utility pole.

A pole-mounted switch (hereinafter referred to as a switch) installed on the top of a utility pole has a structure that can be turned on and off by operating an operation lever provided on the switch body. Hereinafter, the structure and operation outline of a conventional general switch will be described with reference to Patent Document 1. FIG. 7 is a diagram for explaining the structure and operation outline of a conventional general switch 300, and corresponds to FIG. 6 of Patent Document 1. In FIG. FIG. 8 is a view around the operation rings 101 and 102 in FIG.

As shown in FIG. 7, the switch 300 installed on the upper part of the utility pole 250 is provided with an operation lever 301 for turning on and off the switch 300, and the operation lever 301 is provided with a pair of operation levers for moving it. Leashes 151, 152 are attached. One control line 151 is for "on" operation and the other control line 152 is for "off" operation. Each of the operating ropes 151 and 152 hangs down along the utility pole 250, and the operating rings 101 and 102 for hooking the operating tool 200 are attached to the ends thereof, respectively.

The operation rings 101 and 102 are installed at high places out of reach in order to prevent third parties other than the operator 501 from touching them. The operation rings 101 and 102 are downward arrow-shaped annular bodies (see FIG. 8), and when the switch 300 is turned on to close the electric circuit, the operator 501 moves the dedicated operation tool 200 from the ground. Manipulate, hook the hook of the operating tool 200 to the operating ring 101 connected to the operating rope 151 for the “on” operation, and pull down the operating rope 151 through the operating tool 200 . The same operation is performed when the switch 300 is to be turned off.

The switch 300 is also provided with an operating rope fixing device 160 that locks the operating ropes 151 and 152 after the "on" or "off" operation in order to prevent an electric shock accident or the like due to erroneous operation.

On the utility pole 250, scaffolding bolts 260 are installed at predetermined intervals as shown in FIG. Since the operation rings 101 and 102 are ring-shaped, they are swayed by the wind, and are caught on the scaffolding bolts 260, and the switch 300 cannot be turned on and off. , the operating rings 101 and 102 are caught on the scaffolding bolts 260, and an event occurs in which the switch 300 cannot be completely turned on and off. Although the operation rings 101 and 102 also have an elliptical shape as shown in Patent Document 2, the same phenomenon occurs because they are also annular.

In order to solve the above problem, a spherical operation ring has been proposed (for example, Patent Document 3). Since the operation ring described in Patent Document 3 is not an annular body, it is difficult to get caught on the scaffolding bolt 260 .

JP 2007-35533 A JP-A-10-64367 JP 2016-116326 A

Unlike the conventional operation rings 101 and 102, the spherical operation rings described in Patent Document 3 are not ring-shaped, so they are less likely to get caught on the scaffolding bolts 260 of utility poles. However, most of the existing operating rings are arrow-shaped and elliptical as shown in Patent Document 1 and Patent Document 2, so replacement is required to use the spherical operating ring described in Patent Document 3. . In addition, a dedicated operating tool is required to operate the spherical operating ring, and conventional operating tools cannot be used.

As mentioned above, the spherical operating ring described in Patent Document 3 is useful, but its use is very expensive. Moreover, when the spherical operation ring described in Patent Document 3 is used, the existing operation ring becomes unnecessary, which is wasteful. For these reasons, it is required to use the existing operation ring as it is, modify it simply, or attach a member to solve the problem of catching on scaffolding bolts or the like.

An object of the present invention is to operate a switch that can be installed without modifying an existing operating ring, can be operated using an existing operating tool, and can prevent the operating ring from being caught on a scaffolding bolt. It is to provide a ring cover.

The present invention is a switch operation ring cover attached to an end of an operation rope for turning on and off a pole switch, and attached to an operation ring for hooking an operation tool to be used, wherein the space inside the operation ring. and fixing means for fixing the cover body to the operation ring. The switch operation ring cover is characterized in that it closes the space inside the operation ring so that the hook portion of the operation tool can be inserted therethrough.

The switch operation ring cover of the present invention is characterized in that the cover body has a flow path through which air can flow.

The switch operating ring cover of the present invention is characterized in that the fixing means can fix the cover main body with one touch to the existing operating ring attached to the end of the operating rope.

In the switch operation ring cover of the present invention, the cover body has a size that does not cover the ring itself of the operation ring when attached to the operation ring. The ring itself is visible from the outside.

According to the present invention, it is possible to install an existing operation ring without modifying it, operate it using an existing operation tool, and operate a switch that can prevent the operation ring from being caught on a scaffolding bolt. A ring cover can be provided.

FIG. 1 is a perspective view of a switch operating ring cover 1 according to a first embodiment of the present invention. FIG. 2 is a perspective view of the switch operation ring cover 1 attached to the operation ring 101, and FIG. 3 is a perspective view of the switch operation ring cover 1 attached to the operation ring 101 with the operating tool 200 hooked. .

The switch operation ring cover 1 of the first embodiment of the present invention is attached to the ends of the operating ropes 151 and 152 for switching on and off the pole switch 300 installed on the top of the utility pole 250 shown in FIGS. It is a switch operation ring cover that is used by being attached to the operation rings 101 and 102 that are used by hooking the operation tool 200 . Since the operation rings 101 and 102 have the same structure, the case where the switch operation ring cover 1 is attached to the operation ring 101 will be described here as an example.

Before describing the switch operation ring cover 1, the structures and shapes of the operation ring 101 and the operation tool 200 will be described. The operation ring 101 shown here has the same structure and shape as the conventional operation ring 101, and is an annular operation ring in which a rod-shaped member is formed in a downward arrow shape when viewed from the front (see FIG. 8). The operation ring 101 has a projecting portion 107 on an inverted triangular portion 105 when viewed from the front, and an upper portion 108 of the projecting portion 107 has an arc shape.

A space V inside the operation ring 101 consists of an inner space V ₁ formed by the inverted triangular portion 105 and an inner space V ₂ formed by the projecting portion 107 . The space V ₁ is larger than the size of the head 261 of the scaffolding bolt 260 installed on the utility pole 250 , and the scaffolding bolt 260 can easily pass through the inverted triangular portion 105 . The space V2 is also larger than the size of the head 261 of the scaffolding bolt ₂₆₀ so that the scaffolding bolt 260 can easily pass through the protrusion 107 .

The operation ring 101 is flat when viewed from the side, and its thickness is the same as the diameter of the rod-shaped member forming the operation ring 101 . The operating rope 151 is tied to the projecting portion 107 of the operating ring 101 . The diameter d ₁ of the operating rope 151 is smaller than the size h ₁ of the head 261 of the scaffolding bolt 260 .

The manipulator 200 is formed by attaching a hook 201 to the tip of a rod-shaped body 211 (see FIG. 3), like conventional manipulators. The hook portion 201 has a rod-shaped support portion 203 erected on a base 202, and a rod-shaped hook portion 204 is provided so as to be orthogonal thereto. A ball portion 205 having a larger diameter than the hook portion 204 is provided at the tip of the hook portion 204 .

Comparing the diameter d ₁ of the operating rope 151, the diameter d ₂ of the ball portion 205 of the operating tool 200, and the size h ₁ of the head 261 of the scaffolding bolt 260, h ₁ >d ₂ >d ₁ .

The switch operation ring cover 1 includes a cover body 11 that partially closes the space V inside the operation ring 101 and fixing means 51 that fixes the cover body 11 to the operation ring 101 .

The cover main body 11 includes a pair of frames 21 and 22 arranged on the front and back, nets 41 and 42 covering the inside of the pair of frames 21 and 22, and meshes on both sides of the pair of frames 21 and 22. side walls 35, 36 arranged to connect the pair of frames 21, 22; The frame bodies 21 and 22 have the same structure and shape, and the mesh bodies 41 and 42 also have the same structure and shape. The frame 21 and the mesh 41 will be mainly described below.

The frame body 21 is a plate-like body made of metal, and has an outer shape obtained by partially cutting off the upper and lower portions of the space V inside the operation ring 101 when viewed from the front of the operation ring 101, and has a wide opening in the center. 31. The shape of the opening 31 is similar to the outer shape of the frame 21 .

Although the width of the frame 21 is not particularly limited, it is preferable that the width is narrow as long as it is strong enough not to be easily deformed. By narrowing the width of the frame 21, the central opening 31 can be widened. Since the opening 31 in the center serves as a flow passage for wind, widening this makes it difficult for the operation ring 101 to which the switch operation ring cover 1 is attached to swing due to the wind.

Further, the frame 21 is provided with a receiving portion 55 into which the fastener 53 as the fixing means 51 is fitted.

The cover body ₁₁ has a size such that when the switch operation ring cover 1 is attached to the operation ring 101, a space V3 is formed above the switch operation ring cover 1 and a space _V4 is formed below the switch operation ring cover 1. As shown in FIG. The space _V3 is sized such that the scaffolding bolt 260 cannot be inserted but the operating rope 151 can be inserted. The space _V4 is sized such that the scaffolding bolt 260 cannot be inserted and the hook portion 201 of the operating tool 200 can be inserted (see FIGS. 2 and 3).

A central opening 31 of the frame 21 is closed with a mesh 41 . Here, a wire mesh 41 is used for the mesh body. The wire mesh 41 has an opening through which the scaffolding bolt 260 and the hook portion 201 of the operating tool 200 cannot be inserted, and the operation ring 101 to which the switch operation ring cover 1 is attached swings due to the wind and collides with the scaffolding bolt 260. It is strong enough to withstand damage. It is preferable that the wire netting 41 has a wide opening as long as the scaffolding bolt 260 and the hook portion 201 of the operating tool 200 cannot be inserted, because it is less likely to be affected by the wind. The net body 41 may be firmly fixed to the frame body 21, and fixing means is not particularly limited.

The cover main body 11 includes side walls 35 and 36 that connect the sides 27 and 28 of the frames 21 and 22 arranged on the front and back sides. The side walls 35 and 36 may be made of punching metal (punched wire mesh) as long as it has sufficient strength to prevent deformation. On the other hand, the cover main body 11 does not have a top wall and a bottom wall, and the ceiling surface and the bottom surface of the cover main body 11 are open. This is to prevent rainwater from accumulating inside the cover body 11 .

The height of the side walls 35 and 36 is substantially the same as the thickness of the operation ring 101, and when the switch operation ring cover 1 is attached to the operation ring 101, the surface of the frame 21, the operation ring 101, and the frame are in side view. 22 and the operation ring 101 are flush with each other. When the switch operation ring cover 1 is attached to the operation ring 101 in this way, the step between the switch operation ring cover 1 and the operation ring 101 is eliminated in a side view, thereby making it difficult for the scaffolding bolt 260 to get caught.

The fixing means 51 is composed of a belt 52 fixed to the frame 22, a fastener 53 attached to the tip of the belt 52, and a receiving portion 55 into which the fastener 53 provided on the frame 21 is fitted. be. The belt 52 is flexible and can be easily wound around the operation ring 101 . The fastener 53 is a known snap-fit that hooks onto the receiving portion 55 using the elasticity of the material. The receiving portion 55 has a recess into which the projection (claw) 54 at the tip of the snap fit 53 is fitted.

The fixing means 51 are fixed at a total of six positions, one on each of the right and left sides of the projecting portion 107 of the operation ring 101 and two on each of the left and right sides of the inverted triangular portion 105 . Since the operation ring 101 has a step between the protruding portion 107 and the inverted triangular portion 105, if the fixing means 51 is provided so as to be attached to the protruding portion 107 and the inverted triangular portion 105, it is difficult to shift. The switch operation ring cover 1 can be securely fixed.

As long as the belt 52 can firmly fix the switch operation ring cover 1 to the operation ring 101, it is preferable that the belt 52 is narrow or colorless and transparent. Normally, the operation ring 101 is colored red for the ON operation and green for the OFF operation. If the belt 52 is made of an opaque material, when the switch operation ring cover 1 is attached to the operation ring 101, the operation ring 101 is hidden in the belt 52 portion. Visual recognition of the color of 101 becomes difficult.

There is also a method in which the switch operation ring cover 1 or the belt 52 is colored red or green and attached to the operation ring 101 corresponding to each color. are required to be manufactured, which increases the manufacturing cost.

The fixing means 51 is not particularly limited as long as it can reliably fix the switch operation ring cover 1 to the operation ring 101 . A bolt may be used instead of the snap fit 53 . Since the snap fit 53 can be fixed with one touch, it is possible to easily fix the switch operation ring cover 1 to the existing operation ring 101 without removing the operation ring 101 at the site, which is preferable.

When the switch operation ring cover 1 constructed as described above is attached to the operation ring 101 , the operation tool 200 can be hooked, while the operation ring 101 can be reliably prevented from being caught by the scaffolding bolts 260 . Further, the switch operating ring cover 1 has net bodies 41 and 42 in the central portion, and since this serves as a passage for the wind, it is difficult to swing even when the wind blows, so that it can be suitably used on site.

In the case of the switch operation ring cover 1 using the one-touch fastener 53 such as a snap fit for the fixing means 51, the operation ring 101 attached to the operation rope 151 can also be attached to the operation ring 101 on site. Can be installed without removing. Further, the switch operating ring cover 1 is convenient because it can be attached and used without distinguishing between the operating ring 101 for use and the operating ring 102 for turning.

FIG. 4 is a perspective view of the switch operation ring cover 2 of the second embodiment of the invention. FIG. 5 is a perspective view of the switch operation ring cover 2 attached to the operation ring 101. As shown in FIG. The same components as those of the switch operation ring cover 1 of the first embodiment shown in FIGS.

The switch operation ring cover 2 of the second embodiment has the same basic configuration and technical idea as the switch operation ring cover 1 of the first embodiment, and when the switch operation ring cover 2 is attached to the operation ring 101, , the operation tool 200 can be hooked on the operation ring 101, while the scaffolding bolt 260 cannot be inserted to prevent the scaffolding bolt 260 from being caught.

Unlike the switch operation ring cover 1 of the first embodiment, the switch operation ring cover 2 uses a sheet of punching metal for the cover body 12 . The outer shape and outer dimensions of the cover body 12 when viewed from the front are the same as the outer shape and outer dimensions of the cover body 11 when viewed from the front. Therefore, like the switch operation ring cover 1 of the first embodiment, the scaffolding bolt 260 cannot be inserted into the operation ring 101 to which the switch operation ring cover 2 is attached, and the hook portion 201 of the operation tool 200 cannot be inserted. is insertable.

The reason why the punching metal is used for the cover main body 12 in this embodiment is to secure the flow path of the wind. The hole diameter of the punching metal is such that the scaffolding bolt 260 and the hook portion 201 of the operating tool 200 cannot be inserted. The perforated metal preferably has a large pore diameter and a large number of pore diameters because air can easily escape. For this reason, the cover main body 12 may use a single frame body 21 and a mesh body 41 for closing it, as in the case of the cover main body 11 .

The thickness of the cover body 12 is thinner than the thickness of the operation ring 101 . Therefore, when the switch operation ring cover 2 is attached to the operation ring 101, unlike the switch operation ring cover 1, a step occurs in the height direction. Since there is a risk that the scaffolding bolt 260 will be caught if this step increases, a fixing means 61 is provided so that the cover body 12 is positioned at the center of the operation ring 101 in the height direction when attached to the operation ring 101.例文帳に追加

The fixing means 61 is composed of a pair of half pipe-shaped members 67 and 68 connected by a hinge 66 and a fastener 63 for connecting the ends of the pair of half pipe-shaped members. One end of the pipe-shaped member 67 is fixed to the outer peripheral edge 13 of the cover body 12 . The fastener 63 is a known snap fit 63 that hooks onto the receiving portion 65 using the elasticity of the material. A receiving portion 65 into which the snap fit 63 is fitted is provided at one end of the half pipe-shaped member 67 .

The fixing means 61 are fixed at a total of four positions, one on each of the right and left sides of the projecting portion 107 of the operation ring 101 and one on each of the left and right sides of the inverted triangular portion 105 (see FIG. 5). Since the operation ring 101 has a step between the protruding portion 107 and the inverted triangular portion 105, if the fixing means 61 is provided so as to be attached to the protruding portion 107 and the inverted triangular portion 105, it is difficult to shift. The switch operation ring cover 2 can be securely fixed.

It is possible to use something other than the snap fit 63 as the fixing means 61, and the snap fit 63 can be fixed with one touch, so it is preferable as means for attaching the switch operation ring cover 2 to the existing operation ring 101. It is the same as the fixing means 51 of the embodiment.

The width of the half-split pipe-shaped members 67 and 68 and the number of fixing means 61 are not particularly limited. As long as the switch operation ring cover 2 can be firmly fixed to the operation ring 101, it is preferable that the width is narrow, the number is small, and the material is colorless and transparent.

Since the switch operation ring cover 2 of the second embodiment constructed as described above has a simpler structure than the switch operation ring cover 1 of the first embodiment, it can be manufactured at a low cost.

FIG. 6 is a front view of a state where the switch operation ring cover 3 according to the third embodiment of the present invention is attached to the operation ring 101. FIG. The same components as those of the switch operation ring cover 2 of the second embodiment shown in FIGS. 4 and 5 are denoted by the same reference numerals, and descriptions thereof are omitted. The switch operation ring cover 3 of the third embodiment is positioned as a modified example of the switch operation ring cover 2 of the second embodiment, and has the same basic configuration as the switch operation ring cover 2 .

The place where the hook portion 201 of the operating tool 200 can be hooked to the operation ring 101 to which the switch operation ring cover 2 of the second embodiment is attached is only the space V4 formed under the switch operation ring cover ₂ . is. This point is the same for the operation ring 101 to which the switch operation ring cover 1 of the first embodiment is attached.

The operation ring 101 to which the switch operation ring cover 2 is attached does not have a space through which the scaffolding bolt 260 can be inserted. From this point of view, the switch operating ring cover 3 of the third embodiment of the present invention is provided with the concave portion 15 in the cover body 14 .

The concave portion 15 of the cover main body 14 is provided upward so as to be connected to the lower side 16 of the cover main body 14 . The width W ₁ of the concave portion 15 is h ₁ >W ₁ >d ₂ with respect to the size h ₁ of the head 261 of the scaffolding bolt 260 and the diameter d ₂ of the ball portion 205 of the hook portion 201 of the operating tool 200 . Therefore, while the hook portion 201 of the operating tool 200 can be inserted into the concave portion 15, the scaffolding bolt 260 cannot be inserted.

By providing the recessed portion 15 in the cover body 14, it becomes easier to hook the operation tool 200 to the operation ring 101 on which the switch operation ring cover 3 is mounted. Further, the provision of the concave portion 15 increases the number of airflow passages, making the operation ring 101 on which the switch operation ring cover 3 is mounted less susceptible to the wind. The switch operation ring cover 3 of the third embodiment is provided with the recess 15 in the switch operation ring cover 2 of the second embodiment, but the switch operation ring cover 1 of the first embodiment is also provided with the recess 15. be able to.

As described above using the switch operation ring covers 1, 2, and 3 of the first to third embodiments, the switch operation ring cover according to the present invention prevents the scaffolding bolts installed on the utility pole from being inserted. In addition, since the hook portion of the operation tool can be inserted into the space inside the operation ring, it is possible to prevent the operation ring from being caught on the scaffolding bolt while ensuring the function of the operation ring. Further, the switch operation ring cover according to the present invention can be attached without modifying the existing operation ring, and the existing operation tool can be used as it is, so it is preferable in terms of cost.

Further, in the switch operation ring cover according to the present invention, since the cover body has the airflow passage, it is difficult to swing even when the wind blows, and it can be suitably used on site. In addition, the switch operation ring cover according to the present invention can use a one-touch fixing means such as a snap fit, so that the operation ring attached to the operation rope can be fixed on site without removing the operation ring. Easy to install.

Further, the switch operation ring cover according to the present invention has a size that does not cover the ring itself of the operation ring when the cover main body is attached to the operation ring, and the structure and configuration of the fixing means is also attached to the operation ring. In this state, the ring itself of the operation ring is configured to be visible from the outside. Therefore, the switch operating ring cover can be attached and used without distinguishing between the operating ring for use and the operating ring for turning, which is convenient. In addition, since it is not necessary to prepare two kinds of switch operation ring covers for use and for use off, it is preferable in terms of cost.

The switch operation ring cover according to the present invention is not limited to the above-described embodiments, and can be used by being modified without changing the gist of the invention. In the above embodiment, a combination of a frame and a mesh or punching metal is used for the cover main body of the switch operation ring cover, but a plate member provided with slit holes may be used for the cover main body.

Although the preferred embodiments have been described with reference to the drawings, those skilled in the art will readily envision various changes and modifications within the obvious scope of the specification upon reviewing this specification. Accordingly, such changes and modifications are intended to be within the scope of the invention as defined by the appended claims.
