The slide block 220 is a member of a synthetic resin material, and in this embodiment, it is movably coupled to the inside of the guide arm 210 and serves to move the elevating unit 230 to be described later in the longitudinal direction. do.

In addition, the slide block 220 has a hexahedral shape having the same shape as the inner cross section of the guide arm 210, but guide grooves 221 that are movably fitted to the guide protrusions 211 are integrally formed on both sides thereof. It is formed, the receiving groove 222 opened upwardly is integrally formed therein, and a pinhole 223 penetrating the receiving groove 222 is integrally formed in the front surface.

The lifting unit 230 is composed of a lifting block 231 and a mounting table 232, a transfer screw 233, a transfer block 234, a first driving means 235 and a link member 236, this implementation In the case of an example, the slide block 220 and the coupling pin (P) are installed detachably and disposed above the guide arm 210, and the rotating unit 260 and the fire fighting unit 270 and the hook ( 280).

The elevating block 231 is a rectangular parallelepiped block that is fitted to the receiving groove 222 so as to be elevated, and a long hole 231a communicating with the pinhole 223 is integrally formed on the front side, and the pinhole 223 communicated with each other. ) And the long hole (231a), the coupling pin (P) is detachably fitted to interconnect the slide block 220 and the lifting block (231).

The mounting table 232 is a cylinder that has a rectangular parallelepiped shape as a whole and has an upper opening, and is integrally formed on the upper surface of the elevating block 231, and a guide rod 261b to be described later at the inner edge (adjacent to the corner). A guide hole (231a) is integrally formed so that) can be inserted through it.

The transfer screw 233 is rotatably disposed inside the mounting table 232 in a direction orthogonal to the guide arm 210 and serves to transfer the transfer block 234.

The transfer block 234 is installed in the mounting table 232 and is movably fastened to both ends of the transfer screw 233.

The first driving means 235 is a known servo motor, and serves to rotate the transfer screw 233 in the forward and reverse direction so that the transfer block 234 is reciprocally transferred along the inner longitudinal direction of the mounting table 232. .

Here, the first driving means 235 is controlled in operation by the control unit 500 to be described later.

Let it.

For reference, the overlapped portion of the link member 236 is rotatably connected to the bracket 261a of the rotation unit 260 to be described later via a shaft pin.

As an example, when the first driving means 235 rotates in a clockwise direction, the transfer screw 233 connected to the first driving means 235 rotates, and a pair of the transfer screws 233 rotates The transfer block 234 of the transfer block 234 is moved to become closer and closer, and the link member 236 unfolded by the movement of the transfer block 234 is folded and rises upward.

On the other hand, when the first driving means 235 rotates counterclockwise in the folded state of the link member 236, the transfer screw 233 connected to the first driving means 235 rotates, and the transfer screw ( By the rotation of 233, the pair of transfer blocks 234 are moved and gradually move away, and the link member 236, which was folded by the movement of the transfer block 234, is unfolded and accommodated into the interior of the mounting table 232. .

Accordingly, the rotation unit 260 is raised and lowered by the above-described action.

Subsequently, the elastic pad 240 is inserted into the lifting block 231 so as to be intervened between the slide block 220 and the mounting table 232 and serves to elastically support the mounting table 232.

The friction pad 250 is installed on the lower surface of the mounting table 232 to face each other with respect to the lifting block 231 with the elastic pad 240 interposed therebetween, and serves to limit the movement of the slide block 220. .

As an example, when a stress is applied to the mounting base 232, thereby, the mounting base 232 and the lifting block 231 are formed at the bottom of the receiving groove 222 of the slide block 220 via the long hole 231a. It descends to the surface, and at this time, the elastic pad 240 is compressed by the descending mounting table 232, and as the elastic pad 240 is compressed, the friction pad 250 descends through the mounting base 232 The guide arm 210 is abutted against the upper surface, and the movement of the slide block 220 is limited due to friction between the guide arm 210 and the friction pad 250.

Therefore, it is possible to proceed with the lifting operation of the underground transmission line (L) using the lifting unit 230 in a more stable state by the above action.

Subsequently, the rotation unit 260 is composed of a gear box 261 and a rotation base 262, a driven gear 263, a driving gear 264, a second driving means 265 and a mesh body 266, In the case of this embodiment, it is interconnected with the lifting unit 230 and serves to fix and tension the underground transmission line (L).

The driving gear 264 has a size relatively smaller than that of the driven gear 263, and is accommodated in the gearbox 261 to mesh with the driven gear 263.

The second driving means 265 is a known servo motor and serves to rotate the rotation base 262 via the driven gear 263 by rotating the driving gear 264 in the forward and reverse direction.

For reference, the second driving means 265 is operated and controlled by the control unit 500 to be described later.

As an example, when the second driving means 265 is rotated in a clockwise direction, the driving gear 264 connected to the second driving means 265 is rotated, and meshed by the rotation of the driving gear 264 The driven gear 263 is rotated, and due to the rotation of the driven gear 263, the rotation base 262 interconnected via the gear mounting rod 262a is rotated, and in a state in which it is orthogonal to the initial guide arm 210 It is converted into a state in parallel with the guide arm 210.

Conversely, when the second driving means 265 rotates in a counterclockwise direction, the driving gear 264 connected to the second driving means 265 rotates, and the driven gear engaged by the rotation of the driving gear 264 The gear 263 rotates, and the rotation base 262 interconnected via the gear mounting rod 262a is rotated due to the rotation of the driven gear 263, and the guide arm is in parallel with the guide arm 210. It is converted to a state that is orthogonal to (210).

Subsequently, the mesh body 266 is a member in which a grid-shaped mesh is installed, and in the case of this embodiment, it is installed to be inclined downward on both sides of the gearbox 261 to receive and deliver the extinguishing agent from the firefighting unit 270 to be described later. It plays the role of delayed discharge while allowing the received extinguishing agent to be widely sprayed.

The fire fighting unit 270 is composed of a medicine box 271, an idler 272, a push button 273, a coil spring 274, and a rope 275, and in the case of this embodiment, it is disposed on the top of the net body 266 It is installed rotatably at both ends of the rotating base 262 via hinges (H), and plays a role of extinguishing fire by discharging extinguishing agents inside by mutual contact (pressurization) with the power outlet ceiling (C).

The medicine box 271 is a box having a rectangular parallelepiped shape with an inside opening downward, and is disposed at both ends of the rotating base 262 so as to be rotatably installed through a hinge H.

The inside of the medicine box 271 is filled (accommodated) with a granular extinguishing agent, and a cover 271a is provided at the lower part of the medicine box 271 to prevent the extinguishing agent from being discharged without permission. It is installed to be openable and closed, and the cover 271a is interconnected via a push button 273 and a rope (string) to be opened and closed by a vertical motion of the push button 273.

In addition, a hole communicating with the inside is integrally formed on the upper surface of the medicine box 271.

The idler 272 is rotatably installed in the medicine box 271 via a hollow shaft 272a installed to penetrate through a hole formed in the upper surface of the medicine box 271, and the underground transmission line L is installed in the idler 272 ) Are separated from each other so that they can be intervened.

The push button 273 is a member having a'T'-shaped cross section that is fitted to the hollow shaft 272a so as to be liftable and lowered.

The coil spring 274 is disposed between the idler 272 and the push button 273 and serves to elastically support the push button 273 upward.

The rope 275 is a string accommodated in the medicine box 271, one end is connected to the cover 271a and the other end is connected to the push button 273 to interconnect the cover 271a and the push button 273. Plays a role.

As an example, when the firefighting unit 270 is elevated by the lifting unit 230 and the push button 273 presses the ceiling (C) of the power sphere, the push button 273 is rather the ceiling (C) of the power sphere. It is pressed while being pressed by, and at the same time, the coil spring 274 is compressed by the push button 273, and the cover 271a interconnected via the push button 273 and the rope 275 is push button 273 ) Gradually descends, the extinguishing agent filled in the medicine box 271 is quickly discharged to the outside, and the discharged extinguishing agent is primarily deposited in the mesh body 266 and then the mesh body. It is discharged through the grid-shaped hole in (266) and is sprayed into the fire area to quickly extinguish the fire.

Subsequently, the hanger 280 is a member having a hook shape, and in this embodiment, each of the front and rear surfaces of the gearbox 261 is installed to temporarily mount various tools or, if necessary, temporarily mount an electric wire or the like. It can also be used for a purpose.

By forming the hooks 280 on the front and rear surfaces of the gearbox 261 as described above, various tools can be temporarily mounted, thereby improving the convenience of work.

6, the operation switch 300 is an equipment (remote control) equipped with an operation button carried by the operator, in the case of the present embodiment, the first driving means 235 and the second driving means 265 are operated. It serves to output the operation signal to the control unit 500 so as to be possible.

1 to 4 and 6, the fire detection sensor 400 is installed in the transmission line inspection assembly 200 to detect a fire (smoke, heat) and output a fire detection signal to the control unit 500. Plays a role.

6, the control unit 500 is a controller, and in this embodiment, the first driving means 235 and the second driving means 265 are individually operated by receiving an operation signal from the operation switch 300. Control.

In addition, it serves to control the operation of the first driving means 235 so that the push button 273 can be pressed by the ceiling surface (C) of the power tool by receiving a fire detection signal from the fire detection sensor 400, At this time, the second driving means 265 is not operated.

In addition, the control unit 500 operates the first driving means 235 when an operation signal is input from the operation switch 300 to raise and lower the rotating unit 260, the fire detection signal from the fire detection sensor 400 When is input, the first driving means 235 is operated so that the height at which the rotation unit 260 is lifted is relatively higher.

As described above, by setting the control unit 500 in advance, it is very useful because it can fundamentally solve the problem that the push button 273 is pressed against the ceiling C of the electric power tool by mistake of an operator.

7A to 7C are views for explaining the operation of the hanger mechanism for an underground power transmission line arranged according to the present invention, and will be described with reference to this.

Referring to FIG. 1, first, an assembly 200 for inspection of a power transmission line is disposed under an underground transmission line L that is determined to require inspection.

The arrangement method is by moving the slide block 220 along the guide arm 210.

When the power transmission line inspection assembly 200 is disposed under the underground transmission line L as described above, the operator presses the button of the operation switch 300 to operate the first driving means 235 as shown in FIG. 7A. Output an operation signal as possible.

When an operation signal is output from the operation switch 300, the control unit 500 controls the operation of the first driving means 235 according to a preset value.

More specifically, when the first driving means 235 rotates in a clockwise direction, the transfer screw 233 connected to the first driving means 235 rotates, and the transfer screw 233 rotates. As a result, the pair of transfer blocks 234 is moved to get closer and closer, and the link member 236 unfolded by the movement of the transfer block 234 is folded and rises upward.

In addition, as the link member 236 rises, the rotating unit 260 and the fire fighting unit 270 connected to each other via the link member 236 and the bracket 261a are raised and lowered, and at this time, the rotating unit 260 As the underground transmission line (L) is seated on the upper surface of, it is naturally intervened between the idlers 272 constituting the fire fighting unit 270 and rises.

In particular, as shown in Figure 7b, as the load of the underground transmission line (L) is transmitted to the lifting unit 230 through the rotating unit 260, the mounting base 232 and the lifting block 231 are long holes (231a). ) Is lowered to the bottom surface of the receiving groove 222 of the slide block 220, and at this time, the elastic pad 240 is compressed by the descending mount 232, and as the elastic pad 240 is compressed The friction pad 250 is lowered through the mounting table 232 and is brought into contact with the upper surface of the guide arm 210, and the slide block 220 moves due to friction between the guide arm 210 and the friction pad 250. Since is limited, it is possible to proceed with the lifting operation of the underground transmission line L using the lifting unit 230 in a more stable state.

Meanwhile, when the underground transmission line L is lifted to a certain height by the lifting unit 230 as described above, the operator outputs an operation signal so that the second driving means 265 is operated by pressing the button of the operation switch 300. .

When an operation signal is output from the operation switch 300, the control unit 500 controls the operation of the second driving means 265 according to a preset value.

More specifically, when the second driving means 265 rotates in a clockwise direction, the driving gear 264 connected to the second driving means 265 rotates, and the driving gear 264 rotates. The driven gear 263 engaged by the rotation is rotated, and the rotation base 262 interconnected via the gear installation rod 262a is rotated due to the rotation of the driven gear 263 so that it is perpendicular to the initial guide arm 210. It is converted to a state in parallel with the guide arm 210 from the state in which it was formed.

In addition, as the rotary base 262 rotates, the firefighting units 270 interconnected via hinges (H) rotate together, and as a result, the underground transmission line (L) also rotates along with the underground transmission line (L). Since it is pulled as shown in Fig. 7c, the effect of lifting the underground transmission line L appears without excessively lifting the underground transmission line L as in the prior art.

That is, since the underground transmission line (L), which is drooping during the facility inspection, can be sufficiently separated from the support arm 100 even if it is not excessively lifted, it can be sufficiently used even if the ceiling (C) of the power outlet is low, thereby enhancing convenience in use. .

On the other hand, when the inspection of the underground transmission line L is completed, the work may be performed in the reverse order of the above process.

FIG. 8 is a view for explaining another operation of the hanger mechanism for an underground power transmission line arranged according to the present invention, and will be described with reference to this.

When a fire occurs in the power outlet, first, the fire detection sensor 400 detects the fire and outputs a fire detection signal to the control unit 500, and the control unit 500 receives a fire detection signal from the fire detection sensor 400. The first driving means 235 constituting the lifting unit 230 is operated and controlled so that the push button 273 can be pressed by the ceiling surface C of the electric power tool.

In more detail, when the firefighting unit 270 is raised and lowered by the lifting unit 230 and the push button 273 presses the ceiling C of the power outlet, the push button 273 is It is pressed while being pressed by the ceiling (C), and at the same time, the coil spring 274 is compressed by the push button 273, and the cover 271a interconnected via the push button 273 and the rope 275 is As the push button 273 is gradually lowered, it is gradually opened and the extinguishing agent filled in the medicine box 271 is quickly discharged to the outside, and the discharged extinguishing agent is primarily in the net body 266. It is deposited and then discharged through the grid-shaped hole of the mesh body 266 and is sprayed into the fire area to quickly extinguish the fire.

9 is a view for explaining another operation of the hanger mechanism for the power outlet arrangement underground transmission line according to the present invention, will be described with reference to this as follows.

In the process of commissioning the operator to check the normal operation of the power transmission line inspection assembly 200, the rotary unit (L), the rotary unit 260, and the firefighting unit 270 are in an orthogonal state by mistake in the process of commissioning. When descending the 260 and the fire fighting unit 270, there is a problem that the fire fighting unit 270 is caught on the underground transmission line L during the descending process.

However, even if the firefighting unit 270 is caught on the underground transmission line (L) as described above, the firefighting unit 270 is rotatably installed on the rotating unit 260 via the hinge (H), so that the hinge (H) is the center. Since it comes out while rotating, it is possible to descend while passing safely without damaging the underground transmission line (L).

The present invention has been described in detail only with respect to the described specific embodiments, but it is natural for those skilled in the art that various modifications and modifications can be made within the scope of the technical idea of the present invention, and it is natural that such modifications and modifications belong to the appended claims.
