Description

  The present invention relates to a curing cover and a method of using the same, and more particularly to an inexpensive cover that can easily cover an insulator for laying an electric wire on a steel tower.

  Conventionally, in order to install a transmission line carrying high-voltage current on a steel tower, it is necessary to ensure insulation between the power transmission line and the steel tower. Therefore, the transmission line is constructed so that the insulator is supported by the steel tower. It is common to be done.

  This steel tower is painted with rust prevention treatment, but it is necessary to perform rust removal and painting treatment periodically, and if paint adheres to the insulator during the treatment, the insulator There is a risk of deteriorating the insulation of the. For this reason, when performing processing work, such as a rust prevention process of a steel tower, the curing which covers and protects an insulator is performed.

  As the curing of this insulator, before performing the work such as rust removal, for example, prepare a cloth of a size that can cover the insulator, wrap the cloth around the insulator and tie a plurality of places with a string or the like By doing so, he was taking care of the eggplant.

In addition, it is also proposed to prevent the paint from being scattered by a device that attaches a protective plate to the tip of the insulator with an insulating operation rod, stretches the net downward, and winds the net with a drum (for example, , See Patent Document 1).
Japanese Patent Laid-Open No. 7-155656

  However, as the conventional curing of the insulator, the operation of covering the insulator with a cloth and tying a plurality of places with a string is troublesome and takes time and is not efficient. In addition, it is dangerous to tie the cloth with a string in this way, if the tying method is insufficient, it may come off due to strong winds and get entangled with the transmission line where high current flows. .

  In addition, the apparatus described in Document 1 is too large and its use is complicated, and when curing all the insulators in a plurality of places, it is necessary to prepare and attach a plurality of insulators, so the efficiency is poor. In addition, the cost of the apparatus is increased and the cost is increased.

  Therefore, the present invention can cover the insulator with easy work and at the same time improve the workability and reduce the equipment cost by realizing a simple structure that does not easily come off even with strong winds. An object of the present invention is to provide a curing cover that can perform the curing of eggplant inexpensively and efficiently and a method of using the same.

  1st invention of the curing cover which solves the said subject is a curing cover which covers the circumference | surroundings of the insulator which supports the electric wire constructed in a steel tower, ensuring the insulation between this steel tower, Comprising: An insulator can be accommodated inside A plurality of frame members made of a linear elastic material formed in a peripheral shape such as a round shape or a square shape, and a width approximately equal to the length of the frame member, which is longer than an insulator and is substantially parallel to the frame members A sheet member held in a posture to become an inner state of the insulator inside the sheet member and the frame member by expanding the slit in the longitudinal direction of the insulator formed in the sheet member and the frame member. Thus, the periphery of the insulator is covered.

In the present invention, the slits of the frame member and the sheet member can be expanded against the elastic force of the frame member to insert the insulator, and then the frame member is released to close the slit. By making the elastic return, the insulator can be housed inside the frame member and the seat member. Accordingly, it is possible to easily cover the periphery of the insulator for laying the electric wire on the steel tower with a simple structure.
In addition, a ring member through which the frame member is passed is disposed on at least one end side of the sheet member, and the frame member is exposed, whereby the sheet member is pulled by hooking an insulating operation rod or the like of the operation tool. be able to.

  A second aspect of the curing cover that solves the above problems is characterized in that, in addition to the specific matters of the first aspect, a connecting member that connects both sides of the slit is provided.

  In the present invention, the slits of the frame member and the sheet member can be expanded to connect both sides of the closed slit after the insulator is inserted therein. Accordingly, it is possible to prevent the frame member and the slits of the sheet member in which the insulator is housed from being expanded, and the state of covering the insulator is incomplete, or the insulator is removed from the insulator by strong winds or the like. This can be prevented.

  According to a third aspect of the curing cover for solving the above problem, in addition to the specific matter of the first or second aspect, the slit is formed between the overlapping portions of the sheet member and the frame member, and the overlapping portion. It is characterized by expanding so as to eliminate the problem.

  In the present invention, after the slits of the frame member and the sheet member are expanded and the insulator is inserted therein, the slits are closed so that the frame member and the sheet member overlap. Therefore, after the insulator is installed inside the frame member and the seat member, the slit can be reliably closed without performing any work, and the state of covering the insulator becomes incomplete. Can be prevented.

  A fourth aspect of the curing cover for solving the above-mentioned problems is characterized by comprising means for displaying a type corresponding to the electric wire or insulator in addition to the specific matters of the first to third aspects. .

  In the present invention, the type corresponding to the voltage flowing through the electric wire, the size of the insulator, and the like are displayed so as to be visible. Therefore, it is possible to easily select the one to be used by simply looking at the display without measuring the dimensions.

The invention of the use method of the curing cover that solves the above problem is the use method of the curing cover of the first to fourth inventions, wherein the frame members are brought close together, and the sheet member and the frame member are After the slit is expanded against the elastic force of the frame member, the frame member is internally restored, and then the frame member is elastically restored by releasing the force of expanding the slit. As the work of closing the slit and then separating the frame members from each other, by pulling the ring member with an operating instrument and sliding it with respect to the horizontal lever , and for the vertical lever The periphery of the insulator is covered with a sheet member by shaking or pulling down the ring member with an operating instrument .

Can be carried out inexpensively and efficiently.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described with reference to the drawings. 1-5 is a figure which shows one Embodiment of the curing cover based on this invention.

  First, the configuration of the curing cover will be described. In FIG. 1, the curing cover 10 is used so as to cover the periphery of the insulator 110 that is installed to connect and construct a transmission line through which a high-voltage current flows to the tower 100 shown in FIG. When the steel tower 100 is subjected to rust removal, painting, or the like to perform a rust prevention treatment or the like, the insulator 110 is covered (cured) so as to prevent adhesion of paint or the like to cause insulation deterioration.

  In the steel tower 100, for example, an insulator 110 as shown in FIG. 3 is installed on the distal end side of an arm (arm metal) 102 of a main post (main column member) 101, and this insulator 110 is made of a hard porcelain or the like. By forming the diameter part 111 and the small diameter part 112 into a continuous shape, even if some liquid adheres to the surface, the part that continues in the length direction is reduced, so that dielectric breakdown does not occur between both ends. Has been.

  In addition, the insulator 110 has mounting brackets 113 such as so-called cotters embedded at both ends, and the mounting bracket 113 is connected to the arm 102 of the tower 100 and an electric wire (not shown), thereby transmitting power to the tower 100. Are connected and supported, and it is realized to install while ensuring insulation.

  As shown in FIG. 2, the insulator 110 is suspended from the tip of the arm 102 to suspend the power transmission line in a vertical posture, and as shown in FIG. 4, By gripping the power transmission line D so as not to approach the arm 102 via the clamp 114 and the adjustment metal fitting 115 which are disposed on both sides and attached to the mounting metal fitting 113 on one end side, the power transmission line D is held in a lateral orientation. There is a long-length type to support.

  The curing cover 10 is manufactured by assembling the frame members 11a to 11c formed in a ring shape and the sheet member 12 formed in a cylindrical shape. The frame members 11a to 11c are produced by deforming an elastic wire such as a piano wire so as to have an inner diameter larger than that of the large-diameter portion 111 of the insulator 110. The sheet member 12 is formed by cutting a strong cloth material such as canvas (cotton cloth) into a rectangular shape having a width approximately the same as the circumferential length of the frame members 11a to 11c and longer than the length of the insulator 110. Has been made.

  The sheet member 12 is a bag in which the frame members 11a to 11c can be inserted into a total of three places including one place in one end portion in the length direction and two places in the intermediate portion when the sheet member 12 is divided into four in the length direction. The insertion bag 12a formed in a shape and extending in the width direction is formed by sewing a common cloth or the like. The insertion bag 12a is inserted into and inserted into the frame members 11a to 11c, and then the frame member Both ends are sewn and closed so that 11a-11c does not come off.

  Thereby, the sheet member 12 holds the frame members 11a to 11c in a substantially parallel posture in the insertion bag 12a, and the slit 13 cut in the length direction is used by the elastic force of the frame members 11a to 11c. The insulator 110 can be housed inside by expanding it against it, and the slit 13 is closed by releasing the force of expanding the slit 13 and elastically returning the frame members 11a to 11c. Thus, the interior of the insulator 110 can be completely covered. Here, a case where the frame members 11a to 11c are formed in a circular ring shape will be described as an example. However, it is needless to say that the frame members 11a to 11c may have a shape that can make a round around the outer periphery of the insulator 110. For example, you may form in polygons, such as a rectangle. Needless to say, the frame members 11a to 11c may be arranged in accordance with the shape of the insulator 110 without being equal in the length direction and not limited to three.

  Also, the sheet member 12 is sewn with hook and loop fasteners (so-called Velcro (registered trademark)) 14a and 14b made of a support body having hooks and ropes that can be connected and separated from each other on both ends of the slit 13. The hook-and-loop fasteners 14a and 14 are disposed in an intermediate portion when divided into four equal parts in the length direction.

  That is, Velcro (registered trademark) 14a, 14b constitutes a connecting member that connects the sheet members 12 on both sides of the slit 13, and thereby, the seat that houses the insulator 110 by the elastic force of the frame members 11a to 11c. Even if a large external force in the direction in which the member 12 expands the slit 13 is applied by a strong wind or the like, it is possible to restrict (prevent) the slit 13 from expanding, and the state in which the insulator 110 is covered is unsatisfactory. It can be prevented from becoming completely or detached from the insulator 110.

  The sheet member 12 is provided with a plurality of eyelets 15 spaced apart in the circumferential direction on the other end in the length direction where the frame members 11a to 11c are not disposed, and the string member 16 is passed through the eyelets 15. ing.

  Thereby, the sheet member 12 can squeeze and tie the other end portion without the frame members 11a to 11c with the string member 16, and the state of covering the insulator 110 housed inside becomes incomplete, or the insulator 110 Can be prevented from coming off.

  Further, the sheet member 12 is made of a cloth material of a different color for each type so that the use can be identified, and the size and shape of the insulator 110 differ depending on the voltage flowing through the transmission line. Thus, the color of the sheet member 12 is changed in accordance with the size and number of the frame members 11a to 11c, the size of the sheet member 12, and the like. For example, it is green when the voltage of the transmission line is 66 KV, green when 110 KV, white when 220 KV, and green when 500 KV. The reason why 66 KV, 110 KV, and 500 KV are the same color is because the length of the insulator 110 varies greatly from the breakdown voltage, but it goes without saying that the colors may be different.

  Thereby, by looking at the color of the sheet member 12, it is possible to determine the type of the insulator 110 that can be installed, in other words, it is possible to easily select the curing cover 10 to be used according to the voltage flowing through the transmission line. it can. Here, the case where the type of the sheet member 12 is displayed by color will be described as an example. However, the present invention is not limited to this. For example, the type of the insulator 110 and the voltage of the transmission line can be directly discriminated by using different color characters. You may display.

  In addition, 17 in FIG. 1 is a ring member, This ring member 17 is arrange | positioned at the one end part side of the length direction of the sheet | seat member 12, and is attached to three places used as the equal interval of the circumferential direction. ing. The ring member 17 is attached so that a frame member 11a disposed on one end side thereof passes through the inside. Thereby, the sheet member 12 can be pulled by hooking an insulating operation rod (not shown) or the like on the ring member 17.

  Next, the usage method of this curing cover 10 is demonstrated. First, after the frame members 11a to 11c are brought close to each other so that the overall shape of the sheet member 12 is also ring-shaped, the frame members 11a to 11c and the sheet member 12 are grasped, and the frame members 11a to 11c The slits 13 are expanded so as to resist the elastic force, and the insulator 110 is positioned inside. Thereafter, by loosening the force for expanding the slit 13, the frame members 11 a to 11 c are elastically restored so that the sheet member 12 is positioned around the insulator 110.

  Next, the cord member 16 on the other end side of the sheet member 12 is pulled and tied in a squeezed state so that the other end side of the lever 110 is hidden, and then the one end side of the sheet member 12 is pulled to complete the entire lever 110. Is in a state of being housed inside the seat member 12. At this time, in the case of the length-resistant type in which the insulator 110 is lying down as shown in FIG. 4, the seat member 12 can be brought into an interior state by being pulled and slid as it is. In the case of a suspended type in which 110 is vertically suspended as shown in FIG. 2, it can be brought into an interior state by being shaken and lowered.

  After this, by connecting the Velcro (registered trademark) 14a and 14b and restricting the slit 13 from expanding, even if a strong wind or the like is applied, the state of covering the insulator 110 becomes incomplete. It prevents being trapped or detached from the insulator 110.

  Therefore, unlike the prior art, the entire outer peripheral portion of the cloth covering the periphery of the insulator 110 is not tied with a string, and a large apparatus is not used, and the elastic force of the frame members 11a to 11c is used. The insulator 110 can be easily and quickly installed inside the sheet member 12, and the outer surfaces of the plurality of insulators 110 installed on the steel tower 100 can be covered and protected (cured) with high reliability.

  Further, since the curing cover 10 can expand the frame members 11a to 11c, as shown in FIG. 5, even when the insulators 110 are arranged in parallel, it can be covered so as to cover the upper part thereof. In addition, it is possible to effectively prevent falling paint or the like from adhering.

  As described above, in the present embodiment, the curing cover 10 having a simple structure in which the frame members 11a to 11c are simply placed in the insertion bag 12a of the sheet member 12 can easily cover the periphery of the insulator 110 of the steel tower 100 for curing. can do. Therefore, the insulator 110 can be reliably covered by an easy and efficient operation only by adopting the curing cover 10 having a simple structure without using a large-scale device. As a result, the insulator 110 can be effectively cured by an inexpensive apparatus / work.

  As another aspect of this embodiment, although illustration is abbreviate | omitted, in the frame members 11a-11c in the above-mentioned embodiment and the slit 13 of the sheet | seat member 12, although each edge part was a close state, The ends of the members 11a to 11c and the sheet member 12 may be extended so as to overlap and overlap each other. In this case, the slit is formed between the overlapping portions, and when the force for expanding the frame member is loosened, the slit can be closed so as to eliminate the gap caused by the slit, and the paint can be drawn from the gap. And the like can be prevented more surely.

  Although one embodiment of the present invention has been described so far, it is needless to say that the present invention is not limited to the above-described embodiment, and may be implemented in various forms within the scope of the technical idea.

It is a figure which shows one Embodiment of the curing cover which concerns on this invention, and is a perspective view which shows the whole structure. It is an elevation view which shows the steel tower in which the insulator which heals with the curing cover is installed. It is a top view which shows the insulator which uses the curing cover. It is an elevational view showing an installation example of the insulator on the steel tower. It is a top view explaining an insulator whether the curing cover can be diverted.
