[0001] The present invention relates to the field of power grid maintenance, and in particular to an auxiliary device for power grid maintenance. Background Art

[0002] In the circuit transmission system, in the low-voltage circuit between the high-voltage power grid and the user's home circuit, due to the influence of external factors, the wire surface is prone to aging or heating, and under the influence of aging or heating, the wire surface is prone to cracks, which not only reduces the protection of the metal core, but also may cause safety accidents such as leakage. Therefore, the wires need to be inspected and replaced within a certain period of time to maintain the user's home circuit;

[0031] The power assembly connected to the arc plate 41 includes an electric push rod 211, an arc frame 212 and a power unit; the mounting frame 051 is connected to two electric push rods 211, and each electric push rod 211 is electrically connected to the moving vehicle 1; the telescopic parts of all the electric push rods 211 are fixedly connected to the arc frame 212, and the arc frame 212 is rotatably connected to the arc plate 41; the arc plate 41 is connected to a power unit for driving the complete circle formed by the arc plate 41 and the arc plate 2 42 to rotate, and the power unit is connected to the arc frame 212.

[0034] Each clamping wheel 3 is provided with an arc-shaped recess 301 for stably clamping the electric wire 9 .

[0035] The driving wheel 5 is provided with an arc-shaped recess 2 501 .

[0036] The arc-shaped frame 212 is provided with an arc-shaped guide portion 21201 , and the arc-shaped guide portion 21201 is used to guide the wire 9 so that the wire 9 can better enter between the two arc-shaped frames 212 .

[0037] The inner walls of the four sides of the airbag 411 are thick on the side close to the mounting block 7 and thin on the side away from the mounting block 7. This arrangement is used to enable the airbag 411 to stably push the ink pad 412 to move toward the direction close to the wire 9.

[0038] The specific operation of the above-mentioned embodiment 1 is as follows: first, the maintenance personnel place the mobile trolley 1 on the ground. At this time, the mobile trolley 1 is located at the far left between the two electric poles, and the electric wire 9 is above the gap between the two arc frames 212. Then, the telescopic part of the multi-stage hydraulic push rod 111 is controlled to push the mounting frame 051 and the parts connected thereto to move upward through the support plate 112. At the same time, the mobile trolley 1 is controlled to drive the mounting frame 051 and the parts connected thereto to move forward or backward through the multi-stage hydraulic push rod 111 and the support plate 112 in turn to fine-tune the position of the mounting frame 051 and the parts connected thereto until the electric wire 9 is in the middle between the two adjacent front and rear clamping wheels 3, and the electric wire 9 is parallel to the arc-shaped recess 301. Then, the telescopic parts of the front and rear electric push rods 211 are controlled to push the corresponding arc frames 212 and the parts connected thereto to move in the direction close to the electric wire 9, so that the two arc frames 212 fit each other. At this time, Figure 7 As shown, the two arc frames 212 will form an annular slide rail, the arc plate 1 41 and the arc plate 2 42 will fit together and form a complete circular ring, the two half tooth rings 311 will fit together and form a complete tooth ring, and the two adjacent front and rear clamping wheels 3 will clamp the wire 9, and the part of the wire 9 between the left clamping wheel 3 and the right clamping wheel 3 will form a curved portion 901 under the push of the pushing wheel 5, and the curved portion 901 will push the mounting block 7 and the parts connected thereto to move backward through the sensor 8, and push the telescopic portion of the spring telescopic rod 6 to retract. At this time, the sensor 8 will be close to the surface of the wire 9 under the action of the spring telescopic rod 6 to complete the preparation work.

[0039] Then, the mobile trolley 1 is controlled to drive the mounting frame 051 and its connected parts to move to the right through the multi-stage hydraulic push rod 111 and the support plate 112 in turn, so that the clamping wheel 3, the pushing wheel 5 and the sensor 8 move along the length direction of the wire 9. At the same time, from left to right as a reference, the output shaft of the servo motor 312 is controlled to drive the complete ring and its connected parts to rotate clockwise through the gear 313 and the complete gear ring in turn, so that the clamping wheel 3, the pushing wheel 5 and the sensor 8 rotate around the outer surface of the wire 9. As the mobile trolley 1 drives the pushing wheel 5 to move along the length direction of the wire 9, and the pushing wheel 5 always pushes the wire 9, the curved portion 901 will change continuously with the movement and rotation of the pushing wheel 5, and each of the surface of the wire 9 All the inspection points can protrude toward the direction of the sensor 8. Even if each inspection point on the surface of the wire 9 is expanded outward, if there is a crack at the inspection point, the sensor 8 will detect the existence of the crack at the inspection point by induction. At this time, since the surface of the wire 9 at the inspection point is expanded outward, the opening of the crack at the inspection point will be expanded outward, so that the crack opening will be enlarged, which is conducive to the sensor 8 sensing the crack in the surface of the wire 9, making the sensor 8's inspection result of whether there is a crack on the surface of the wire 9 more accurate, so as to avoid the problem that the crack on the surface of the wire 9 is relatively small and the wire 9 is installed on the electric pole, which makes it difficult for maintenance personnel to fully check whether there is a crack on the surface of the wire 9.

[0040] It should be noted that when the sensor 8 detects cracks on the surface of the wire 9, the sensor 8 will transmit the detected information to the control system, and the control system will control the mobile car 1 to stop moving. At the same time, the servo motor 312 will stop working, and then the air pump 413 will be controlled to transport gas into the airbag 411 through the telescopic air tube 414, so that the airbag 411 will expand toward the direction close to the wire 9, and the expanded airbag 411 will push the printing plate 412 to expand toward the direction close to the wire 9. When the printing plate 412 contacts the surface of the wire 9, as the airbag 411 continues to expand, the printing plate 412 will print a mark on the surface of the wire 9. After marking, the air pump 413 is controlled to extract the gas in the airbag 411 through the telescopic air tube 414, so that the airbag 411 drives the printing plate 412 to return to the initial position. In this way, by printing a mark on the surface of the wire 9, the maintenance personnel are reminded of the specific location of the crack on the surface of the wire 9.

[0041] When the mounting frame 051 and the parts connected thereto need to be moved away from the electric wire 9, firstly, the telescopic parts of the front and rear electric push rods 211 are controlled to drive the corresponding arc frame 212 and the parts connected thereto to move in a direction away from the electric wire 9, so that the arc frame 212 and the parts connected thereto return to their initial positions. Then, the telescopic parts of the multi-stage hydraulic push rods 111 are controlled to drive the mounting frame 051 and the parts connected thereto to move downward through the support plate 112, so that the mounting frame 051 and the parts connected thereto return to their initial positions, thereby keeping the mounting frame 051 and the parts connected thereto away from the electric wire 9.

[0042] It should be noted that before the present equipment is put into operation, the maintenance personnel place the tools and materials needed for maintaining the electric wires 9 in the storage cavity 101, and transport the tools and materials needed for maintaining the electric wires 9 by the mobile cart 1. There is no need for the maintenance personnel to carry the tools and materials needed for maintaining the electric wires 9, which can reduce the difficulty of the maintenance personnel's work. This avoids the problem that when the maintenance personnel maintain the circuits in the alleys, the maintenance personnel still need to carry the tools and materials needed for maintaining the electric wires 9 because the truck cannot drive in the alleys, thereby increasing the difficulty of the maintenance personnel in maintaining the circuits.

[0043] Example 2

[0044] Based on Example 1, Figure 1-Figure 4 As shown, the mounting frame 051 is composed of a slide bar 511, a fixed block 512, a spring member 513 and a U-shaped mounting plate 514; the support plate 112 is bolted to two slide bars 511; each slide bar 511 is slidably connected to a fixed block 512; all the fixed blocks 512 are commonly fixedly connected to a U-shaped mounting plate 514, and the U-shaped mounting plate 514 is bolted to all the electric push rods 211; each slide bar 511 is sleeved and fixedly connected to two spring members 513 distributed up and down, and each spring member 513 is fixedly connected to the corresponding fixed block 512.

[0045] The specific working of the above-mentioned embodiment 2 is as follows: Taking into account that the mobile cart 1 is affected by the ground during its movement, when the mobile cart 1 passes through a pit on the ground, the mobile cart 1 will rigidly pull the wire 9 downward through the lifting assembly, power assembly, U-shaped frame 2 and clamping wheel 3 in sequence, resulting in serious creases in the fixed position of the wire 9 and the pole, thereby accelerating the aging of the wire 9.

[0046] By configuring the mounting frame 051 to consist of a slide bar 511, a fixed block 512, a spring member 513 and a U-shaped mounting plate 514, when the mobile cart 1 passes through a pit on the ground, the mobile cart 1 will pull the slide bar 511 through the lifting assembly to slide downward on the fixed block 512. At this time, the upper spring member 513 will be stretched and the lower spring member 513 will be compressed, so that the mobile cart 1 changes from rigidly pulling the wire 9 downward to flexibly pulling the wire 9, thereby avoiding the problem that when the mobile cart 1 passes through the pit on the ground, the mobile cart 1 will rigidly pull the wire 9 downward, resulting in serious creases in the fixed position of the wire 9 and the pole.

[0047] Example 3

[0048] Based on Example 2, Figure 1-Figure 5 and Figure 7 As shown, it also includes a U-shaped connecting plate 612 and a DC motor 613; bristles are arranged on the outer surface of the driving wheel 5; the arc plate 1 41 is fixedly connected to the mounting rod 611; the mounting rod 611 is fixedly connected to the U-shaped connecting plate 612, and the U-shaped connecting plate 612 is rotatably connected to the driving wheel 5; the U-shaped connecting plate 612 is bolted to the DC motor 613, and the output shaft of the U-shaped connecting plate 612 is fixedly connected to the driving wheel 5, and the DC motor 613 is electrically connected to the battery on the arc plate 2 42.

[0049] The specific working of the above-mentioned embodiment 3 is as follows: Considering that the outer skin of the wire 9 is a plastic product, and the plastic product is easy to release plasticizer when the temperature rises, and the plasticizer will mix with dust to form dirt on the outer skin of the wire 9, and the dirt will cover the cracks on the surface of the wire 9, thereby causing the sensor 8 to still find it difficult to detect whether there are cracks on the outer skin of the wire 9.

[0050] The existing method of dealing with dirt is usually to remove the dirt by a scraper ring. However, since the dirt is in a wet state when it is not dried and in a solidified state when it is dried, it is difficult for the bristles to remove the solidified dirt. The scraper ring will scrape the wet dirt into the cracks on the surface of the wire 9, and then the cleaning effect of removing the dirt by the bristles or the scraper ring is not good.

[0051] Therefore, bristles are added to the outer surface of the driving wheel 5, so that when the driving wheel 5 rotates around the outer surface of the wire 9 driven by a complete circle, the bristles on the driving wheel 5 can apply a circumferential rotational cleaning force to the dirt on the surface of the wire 9. At the same time, the output shaft of the DC motor 613 is controlled to drive the bristles to rotate through the driving wheel 5, so that the bristles on the driving wheel 5 can not only apply a circumferential rotational cleaning force to the dirt on the surface of the wire 9, but also provide a lateral rotational cleaning force. During this cleaning process, if the dirt is in a wet state, the circumferential and lateral rotational forces applied by the bristles on the driving wheel 5 to the wet dirt will be greatly reduced. Under the action of the cleaning force, the wet dirt will be removed by the bristles on the pushing wheel 5. If the dirt is in a solidified state, the curved portion 901 will change continuously with the movement and rotation of the pushing wheel 5, and the solidified dirt on each inspection point on the surface of the wire 9 will be constantly torn apart, and the solidified dirt will be broken apart. Then, under the action of the circumferential and lateral rotation cleaning force exerted by the bristles, the broken solidified dirt will be removed by the bristles on the pushing wheel 5 to avoid the dirt blocking the cracks in the surface of the wire 9, thereby causing the sensor 8 to still be difficult to insert into the cracks in the outer skin of the wire 9.

[0052] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
