Description

Telegraph Insulator Wrought Iron {Supporting bar for fixing the insulator at the electric pole}

The present invention relates to a telegraph pole insulated wedge.

The low voltage human insulator is for insulating and fixing a distribution line or a communication line through which a relatively low voltage current flows, and as shown in FIG. 1 (a diagram showing a conventional state in which a wire is connected to a telephone pole), an inlet fixed to the tension clamp 200 is shown. Hold the wire 300 to support it.

At this time, the tension clamp 200 is connected to the insulator body 130 of the human insulator 100 through the human bind wire 400, typically the insulator body 130 is fixed to the telegraph pole 10, etc. ) Is firmly fixed to a fixed shaft 131 positioned in a vertical direction with the human bind line 400. That is, the human bind line 400 is fixed as if wrapping the child body 130.

On the other hand, since the wire 300 is a material that repeats the expansion and contraction according to the temperature, it can be stretched downward while expanding by a high external temperature in the summer (see arrow) By the way, when the wire 300 is stretched As the tension of the wire 300 becomes weaker, the tightening of the human bind wire 400 surrounding the insulator 130 is relaxed, and the insulator 130 receives continuous force downward by the load of the wire 300. There is a problem that the human bind wire 400 surrounding the circumference of the) is separated from the insulator 130 by sliding. Of course, in contrast, by forming a concave groove on the periphery of the insulator 130, it is possible to prevent the human bind wire 400 can be easily separated, but this is not a perfect coupling structure, the expansion of the wire 400 by the abnormal high temperature At the time, an accident in which the human bind line 400 is separated from the insulator 130 may be separated.

On the other hand, the wire 300 fixed to the human insulator 100 should be spaced apart from the suspension insulator sufficient distance to support the wire flowing a relatively high voltage current. This is because the wire 300 through which the low voltage current flows can be easily affected by the electromagnetic field generated around the high voltage wire. Therefore, in the prior art, the human insulator 100 could not be installed on a fully-arranged fixed suspension insulator. However, by installing the high-voltage and low-voltage wire separately in one telephone pole, there was a problem of increasing the number of members as well as the installation work of the wire.

Unexplained withdrawal number '110' is a number withdrawing the belt, is connected to the rack 120 for supporting the insulator 130, while wrapping the telephone pole 10, the human insulator 100, the telephone pole 10 ).

Accordingly, the present invention has been made to solve the above problems, it is possible to maintain a stable fixing of the wire by preventing the human bind wire is separated from the insulator even when the length of the wire changes due to temperature changes It is a technical task to provide a telescopic pole insulator of fixed poles that can be installed efficiently while maintaining the optimal environment, as well as low pressure insulators in which high voltage current flows.

And a plurality of protrusions disposed on the movable grooves to be detachably interlocked with the locking grooves, and movable springs along the moving paths, and a ball spring springs to support the latches so that the protrusions are engaged with the locking grooves while being disposed in the moving paths surrounding the fixing bars. And a connection case in which the other end of the elastic body is inserted and fixed into the hollow opened upward, and one surface facing the elastic body is gradientd to be farther from one end of the elastic body toward the lower side, and is rotatably fixed to one end of the elastic body and the upper surface thereof. A stopper which is located below the connection case and has a stopper portion protruding upward from the end; A hinge spring for supporting the upper part of the elastic buffer is the elastic body so as to be in contact with the bottom of the other end or a connecting casing guide; And

A rack fixed to the connection case;

Consisting of the stopper,

In the present invention described above, the position of the insulator body is changed according to the change in the length of the wire while the pulling by the elastic body is continuously applied to the insulator body, and such a position change is made in response to the tension received by the human bind wire, which is always stable. It is possible to maintain the combined state, and when the suspension insulator is installed on one piece of iron, there is an effect of easily adjusting the fixed position of the human insulators.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is an exploded perspective view showing a state of the fixing rod according to the present invention, will be described with reference to this.

Wrought iron 20 according to the present invention is a belt 110 for wrapping and fixing the telephone pole 10, the support 20 is fixed to the belt 110, rack 120 is fixed to the support 20 and the wire The human body bind wire 400 of the tension clamp 200 fixing the 300 is wrapped around the circumferential surface and fixed to the rack 120 in the longitudinal direction through the fixing shaft 131 with the insulator 130; The support 20 and the rack 120 is made of a support 140 to support the bullet. That is, the rack 120 according to the present invention may be connected to the fixing base 140 to change the direction of the force received by the insulator 130 from the wire 300.

The holder 140 is a strip of 'b' shape and elastic material elasticity in the direction in which both ends are in contact with each other and one end is fixed to the belt 110 so that both ends are downward, and the rack Connection case 141 having a hollow (141a) is fixed to the 120 and the other end of the elastic body 142 is inserted, rotatably fixed to one end of the elastic body 142 and the other end of the elastic body 142 at the end It consists of a stopper 143 having a locking protrusion 143a for holding the end, and a hinge spring 144 that supports the stopper 143 to be pushed upward in the direction of the elastic body 142.

In more detail, the fixing unit 140 is opened by the tension applied by the wire 300, while receiving the force in the direction in which both ends are always in contact with each other by its elasticity, the maximum width of the stopper It is limited to the length of (143). This will be described in detail below.

For reference, a fastening hole 142b may be formed at one end of the elastic body 142 for fastening with the belt 110 fixed to the telephone pole 10, and the fastening hole 142b may be fastened such as a bolt or a pin. As the means penetrate, the elastic body 142 is firmly fixed to the belt 110 via them.

Subsequently, the connection case 141 has a hollow 141a which is opened upward, and forms a shape in which one surface facing the elastic body 142 is gradientd and becomes narrower downward. That is, the one surface is farther from one end of the elastic body 142 toward the lower side. Meanwhile, a through hole 141c is formed in the bottom surface of the connection case 141, and the other end of the elastic body 142 penetrates through the through hole 141c. At this time, the other end of the elastic body 142 is provided with an extended molded hanger 142a, when the hanger 142a is fitted into the through hole 141c, the elastic body 142 and the connection case 141 cannot be separated. Therefore, they are tightly coupled to each other.

An opening 141b may be formed on one surface of the connection case 141 facing the elastic body 142. The opening 141b prevents excessive contact between the protrusion and the connection case 141 even when the bent elastic body 142 is completely in contact with the protrusion of the fastening means penetrating through the fastening hole 142b.

As a result, the fixing unit 140 is the operation of the elastic body 142 is transmitted to the connection case 141 as it is, the stopper 143 is the elastic body 142 by the hinge spring 144 irrespective of the operation of the elastic body 142. Since the ball is elastically supported, the upper surface of the stopper 143 is always in contact with the other end of the elastic body 142.

3 is a view showing the operation of the fixing rod according to the present invention, will be described with reference to this.

As shown in Figure 3 (a) and 3 (b), the human insulator (100 ') is fixed to the belt 110 to the telephone pole 10, the fixing base 140 is fixed to the belt 110 The rack 120 is fixed to the holder 140, while the insulator 130 is fixed to the rack 120. That is, the rack 120 and the insulator 130 may change the extraction direction of the human bind wire 400 up and down by the folding bracket 140 that is folded.

In more detail, the human insulator 100 ′ having the above-described configuration holds and holds the wire 300 having tension.

As shown in FIG. 3 (a), when the wire 300 contracted in winter pulls the insulator 130 with a relatively large tension, the elastic body 142 having an elastic force smaller than the tension is opened by tension. However, since the elastic body 142 should not be opened indefinitely by the tension, the locking protrusion 143a of the stopper 143 is engaged with the other end of the elastic body 142 while the elastic body 142 is pulled by the tension of the wire 300. Limiting losing range.

As shown in FIG. 3 (b), the wire 300 expanded in the summer is relatively weak in tension applied to the insulator 130, while the insulator 130 is downward due to the sagging wire 300. The direction of force is changed. As a result, while the tension of the wire 300 is smaller than the elasticity of the elastic body 142, the distance between both ends of the elastic body 142 becomes narrow, and one surface of the connection case 141, which is gradientd as shown, It is inclined while approaching one end. Of course, the rack 120 and the insulator 130 positioned in the connection case 141 are inclined downward, and as a result, the pulling direction of the electric wire 300 and the fixed shaft 131 form a right angle with each other. ) Is prevented from slipping away from the insulator 130.

In addition, since the wire 300 is effective in response to the tension weakening of the wire 300, the fall of the wire 300 can be alleviated to some extent in the summer, and the human body bind wire corresponds to the pulling direction of the wire 300. Since the direction of 400 may be changed, it is possible to prevent a problem that the insulator 130 disposed in the longitudinal direction by the fixed shaft 131 is damaged by being subjected to a biased external force.

On the other hand, the stopper 143 is rotatably fixed to one end of the elastic body 142, so that the upper surface is always in contact with the upper surface of the elastic body 142, while the elastic body 142 is folded, the connection case is the stopper 143 Pushed downward, the stopper 143 does not interfere with the movement of the rack 120 and the insulator 130, thereby smoothly operating the human insulator 100 '.

Figure 4 is an exploded perspective view showing the appearance of the stopper according to the present invention, will be described with reference to this.

The stopper 143 fixed to the rack 120 according to the present invention can change the length, it is possible to adjust the maximum separation distance between the two ends of the elastic body 142. To this end, the stopper 143 is a fixed portion (1431) rotatably connected to one end of the elastic body 142, a moving portion (1432) movably engaged with respect to the fixed portion (1431), high When the position between the government part 1431 and the moving part 1432 is determined, the fastening part 1433 is fixed.

The fixing part 1431 is a projection arm 1431a which rotatably engages with one end of the elastic body 142 and protrudes to face the rotation arm 1431a and has a guide groove 1431c formed along the longitudinal direction. 1431b.

The moving part 1432 is formed with a locking protrusion 143a at the distal end, and an insertion groove 1432a into which the protrusion 1431b is inserted is formed at an opposite portion of the locking protrusion 143a to which the fixing part 1431 is in contact. An inner surface of the insertion groove 1432a is formed with a guide protrusion 1432b sliding into the guide groove 1431c.

The fastening part 1433 has a screw-shaped bolt shape and is fixed to communicate with the fitting groove 1432c and the fitting groove 1432c formed through the moving part 1432 in the longitudinal direction of the insertion groove 1432a. The fitting grooves (not shown) formed in the (1431) are each fitted in sequence. At this time, a screw thread corresponding to the thread of the fastening part 1433 is formed on the inner circumferential surface of the fitting groove (not shown) formed in the fixing part 1431. When the fastening part 1433 is turned, the fixing part 1431 and the moving part ( The distance of 1432 is adjusted.

That is, when the coupling part 1433 is turned to release the coupling with the fitting groove (not shown) formed in the fixing part 1431, the protrusion of the protrusion 1431b of the fixing part 1431 is along the insertion groove 1432a. The fixing part 1431 and the moving part 1432 move away from each other while moving, and when the coupling is tightened, the fixing part 1431 and the moving part 1432 come closer.

5 is a view illustrating various adjustment modes of the rack according to the present invention, which will be described with reference to the drawing.

5 (a) is a state in which the length of the stopper 143 is usually adjusted by adjusting the fastening part 1433, Figure 5 (b) is formed in the fixing part 1431 by turning the fastening part (1433) Figure 5 (c) is a state in which the length of the stopper 143 is maximized by releasing the coupling with the fitting groove (not shown), and the length of the stopper 143 is minimized by tightening the fastening part 1433. to be.

As described above, the length of the stopper 143 can be easily adjusted according to the installation environment, thereby minimizing the burden of the insulator 130 on the external force that varies according to the installation environment, thereby racking according to the present invention ( 120) can be applied in various environments.

Figure 6 is an exploded perspective view showing a state of a wrought iron according to the invention,

Figure 7 is a cross-sectional view showing the movement of the latch is installed on the wrought iron according to the present invention, it will be described with reference to this.

The support 190 according to the present invention is firmly fixed to the telegraph pole 10 via the belt 110, and is coupled to the fixing stand 140 while the latch 145 protruding from one end of the elastic body 142 is fitted. At this time, the latch 145 is connected to the elastic body 142 and the fixed bar 142c is spaced apart, the fixed bar 142c is disposed in the ball spring 146. Subsequently, the latch 145 has a plurality of protrusions 145a protruding from each other, and the protrusions 145a prevent the movement of the latch 145 so that the fixing unit 140 can be stably fixed.

On the other hand, the support 190 is a movement path 192 is formed along the longitudinal direction, a plurality of engaging grooves 191 are formed at regular intervals along the movement path 192. At this time, the engaging groove 191 is detachably engaged with the projection (145a) of the latch 145. Therefore, the moving path 192 should have a sufficient width for the movement of the latch 145. Subsequently, the ball spring 146 pushes the latch 145 toward the locking groove 191 so that the protrusion 145a is always engaged with the locking groove 191 (see FIG. 7A). At this time, since the elastic force of the elastic spring 146 is sufficiently stronger than the elastic force of the elastic body 142, even if the wire 300 is contracted to pull the elastic body 142, the elastic spring 146 does not operate easily. As a result, the latch 145 may always maintain its state while the protrusion 145a is fitted in the locking groove 191.

On the other hand, when it is necessary to change the position of the human insulator 100 'in order to fix the suspension insulator (not shown) to the wrought iron 20, the worker, as shown in Figure 7 (b), fixed bar 142c ) To remove the protrusion 145a from the locking groove 191, and then move the latch 145 (see FIG. 7 (c)) to place the latch 145 at a desired position. Of course, the fixing stand 140 of the latch 145 is moved to the position, and eventually the entire human insulator 100 'is disposed at the position.

The drawing number '193', which has not been described, is an opening line, and the fixed bar 142c is movably drawn out, and the ball spring 146 is a hole which opens the moving path 192 in a width that can be held so as not to be separated.

Subsequently, the support 190 further includes support caps 194 and 194 '. The support caps 194 and 194 ′ cover and close the open spaces at both ends of the support 190, and complement the support force of the support 190 weakened due to the formation of the opening line 193. To this end, the support caps 194 and 194 'are formed in pairs disposed at both ends of the support 190, and a support protrusion 194a inserted into the moving path 192 is formed on one surface facing the support 190. In the circumferential portion of the support protrusion 194a, an engaging groove 194b to which the edges of both side surfaces of the support 193 are engaged is formed. In this case, the support protrusion 194a may have a recess protrusion 194c inserted into the opening line 193.

Accordingly, the support protrusion 194a and the folding protrusion 194c may fold one surface of the support 190 opened by the opening line 193 to prevent the support 190 from being retracted by external pressure. In addition, since the edges of both end surfaces of the support 190 are fixed through the engaging groove 194b, the support 190 may be prevented from being opened by the load applied by the support 140.
