[0002] Insulators are a type of insulator that connects high-voltage transmission line poles (towers) to transmission lines. They are not only required to have strong mechanical properties, but also to have good insulation performance. Since the insulators of transmission lines are under the action of operating voltage for a long time, coupled with the erosion of the open-air environment, the insulation performance of the insulators may deteriorate, resulting in poor insulators, and thus the insulators need to be regularly tested for resistance.

[0019] 1. In the present invention, the distance between two adjacent spacing adjustment components is conveniently adjusted by setting the first motor and the first bidirectional threaded rod. The distance between two arc frames can be adjusted by setting the spacing adjustment component. No matter whether it is a vertical insulator string or a horizontal insulator string, it can be wrapped by the arc frame and then supported by the walking component to walk on the vertical insulator string or the horizontal insulator string. During the walking process, the resistance of the insulator can be detected by the detection component.

[0020] 2. In the present invention, when the insulator in the horizontal state is detected, after the device is hoisted, the arc frame is positioned on both sides of the insulator, and then the third motor is started to drive the second bidirectional threaded rod to rotate, so that the two sets of arc frames move toward each other, and the pull rope will pull the fixed plate to slide so that the first mounting frame drives the first contact wheel to contact the outside of the insulator, and the second connecting plate drives the pressure roller to slide, and the pressure roller contacts the inclined plate, so that the second contact wheel contacts the top of the insulator, and the crawler also contacts the outside of the insulator.

The arc frame 60 is fixedly connected to the nut blocks 503, and the third motor 501 is used to drive the second bidirectional threaded rod 502 to rotate. Through the guidance of the guide frame 50, the two nut blocks 503 slide toward each other, and the nut blocks 503 drive the two arc frames 60 to slide toward each other, so that the first contact wheel 1101, the second contact wheel 1204 and the track 1002 can contact the outside of the insulator.

[0063] In combination with the above technical scheme, the walking assembly in this embodiment includes a side frame 100 fixedly connected to the outside of the arc frame 60, a side plate 1003 fixedly connected to the side frame 100, two driving wheels 1004 rotatably connected to the side frame 100, and a track 1002 mounted on the outside of the driving wheel 1004. The outside of the side frame 100 is fixedly connected to a fourth motor 1001, and the output end of the fourth motor 1001 is fixedly connected to the driving wheel 1004. The side frame 100 is used to support the track 1002, and the fourth motor 1001 is used to drive the driving wheel 1004 to rotate, and the driving wheel 1004 drives the track 1002 to transmit, thereby realizing the walking of the present equipment.

[0064] In this embodiment, a first mounting frame 110 is further provided at the bottom of the arc frame 60, and a first resistance wheel 1101 is rotatably connected to the first mounting frame 110, a first support plate 1102 is fixedly connected to the outside of the arc frame 60, a third guide rod 1103 is fixedly connected to the outside of the first mounting frame 110, the third guide rod 1103 penetrates the first support plate 1102 and is fixedly connected to a fixing plate 1104, and a second spring 1105 is sleeved on the outside of the third guide rod 1103, and the second spring 1105 plays a resetting role.

[0065] In this embodiment, a second support plate 1205 is fixedly connected to the bottom of the guide frame 50, a second mounting frame 120 is provided below the second support plate 1205, a second interference wheel 1204 is rotatably connected to the bottom of the second mounting frame 120, a fourth guide rod 1206 is fixedly connected to the top of the second mounting frame 120, the fourth guide rod 1206 passes through the second support plate 1205, a third spring 1207 is sleeved on the outside of the fourth guide rod 1206, both ends of the third spring 1207 are fixedly connected to the second support plate 1205 and the second mounting frame 120, the third spring 1207 plays a resetting role, and the diameters of the first interference wheel 1101 and the second interference wheel 1204 are both greater than or equal to the gap distance between two adjacent insulators.

[0066] Specifically, the top of the arc frame 60 is fixedly connected to the second connecting plate 1201, the outside of the second connecting plate 1201 is rotatably connected to the pressure roller 1202, the top of the second mounting frame 120 is fixedly connected to the position of the pressure roller 1202, the outside of the arc frame 60 is fixedly connected to the guide block 1107, the first support plate 1102 and the guide block 1107 are both provided with through holes, the outside of the fixed plate 1104 is fixedly connected to the pull rope 1106, one end of the pull rope 1106 passes through the through holes in the first support plate 1102 and the guide block 1107 and is fixedly connected to the guide frame 50.

[0067] The above technical solution is explained as follows: the two arc frames 60 move toward each other, and because one end of the pull rope 1106 is fixed to the guide frame 50, under the relative action, the pull rope 1106 pulls the fixed plate 1104 to slide, the fixed plate 1104 pushes the third guide rod 1103 to slide, and the third guide rod 1103 pushes the first mounting frame 110 to slide, so that the first mounting frame 110 drives the first abutting wheel 1101 to abut against the outside of the insulator; at the same time, the two arc frames 60 move toward each other, and also drive the pressure roller 1201 through the second connecting plate 1201. 02 slides, the pressure roller 1202 contacts the inclined plate 1203, and the second mounting frame 120 drives the second contact wheel 1204 to move downward through the contact of the pressure roller 1202 with the inclined plate 1203, so that the second contact wheel 1204 contacts the top of the insulator, and the track 1002 also contacts the outside of the insulator to achieve all-round coverage of the insulator. This arrangement can not only allow the frame 10 to walk stably on the insulator, but also prevent the frame 10 from easily falling off the insulator even if encountering strong winds at high altitudes, and the safety is also higher.

[0068] In order to detect the insulator, a detection component is provided in the present embodiment, and the detection component includes a rotating rod 301 fixedly connected to the output end of the second motor 30, an articulated arm 302 fixedly connected to the outside of the rotating rod 301, and a detection rod 303 fixedly connected to the outside of the articulated arm 302.

The detection rod 303 is an existing product, for example, the detection rod 303 in the HB-RT20 insulator resistance tester can also be used. The camera 401 is used to take pictures of the insulator for the staff to observe the pollution of the insulator. In addition, a communication system can be provided to transmit the real-time photos and data to a handheld terminal or a background terminal. The driving components of the present embodiment, such as the motor, are all remotely controlled, and the remote control technology is a prior art.

[0069] The method of using this embodiment is as follows:

[0070] When testing the insulator in a horizontal state, the details are as follows:

[0071] Connect the first lifting rope 202 to the drone (or use a hanger and the first fixing frame 20 for mounting, or use other lifting methods, as long as the method or method that can be thought of by those skilled in the art can be used for lifting the rack 10 in this embodiment);

[0072] The frame 10 is hoisted to the top of the insulator by a drone, and the arc frame 60 is positioned on both sides of the insulator, and then the third motor 501 is started to drive the second bidirectional threaded rod 502 to rotate, and the two nut blocks 503 are guided by the guide frame 50 to slide toward each other, and the nut blocks 503 drive the two arc frames 60 to slide toward each other, so that the first contact wheel 1101, the second contact wheel 1204 and the crawler 1002 can contact the outside of the insulator;

[0073] When the two arc-shaped frames 60 move toward each other, since one end of the pull rope 1106 is fixed to the guide frame 50, the pull rope 1106 pulls the fixing plate 1104 to slide, and the fixing plate 1104 pushes the third guide rod 1103 to slide, and the third guide rod 1103 pushes the first mounting frame 110 to slide, so that the first mounting frame 110 drives the first abutting wheel 1101 to abut against the outside of the insulator;

[0074] At the same time, the two arc-shaped frames 60 move toward each other, and the second connecting plate 1201 drives the pressure roller 1202 to slide, and the pressure roller 1202 contacts the inclined plate 1203. The contact of the pressure roller 1202 with the inclined plate 1203 causes the second mounting frame 120 to drive the second contact wheel 1204 to move downward, so that the second contact wheel 1204 contacts the top of the insulator, and the crawler 1002 also contacts the outer side of the insulator.

[0075] Then, the fourth motor 1001 is started to drive the driving wheel 1004 to rotate, and the driving wheel 1004 drives the crawler 1002 to transmit, so that the frame 10 can move outside the insulator;

[0076] The second motor 30 drives the rotating rod 301 to rotate, so that the detection rod 303 contacts the outside of the insulator, thereby realizing the resistance detection of the insulator.

[0077] Embodiment 2:

[0080] The arc frame 60 is fixedly connected to the outside of the second fixed frame 704, the second fixed frame 704 is rotatably connected to a pin shaft 701, the first gear 702 is fixedly connected to the outside of the pin shaft 701, the second fixed frame 704 is rotatably connected to a second gear 703, the first gear 702 is meshed with the second gear 703, the pin shaft 701 is fixedly connected to the outside of the rotating frame 70, the rotating frame 70 is rotatably connected to a top wheel 705, and the top wheel 705 corresponds to the abutment rod 801;

[0081] The outside of the fixed plate 1104 is fixedly connected to the second guide rod 708, the external sliding sleeve of the second guide rod 708 is provided with a guide sleeve 7011, the outside of the guide sleeve 7011 is fixedly connected to the rack 706, the rack 706 corresponds to the second gear 703, the outside of the rack 706 is fixedly connected to the first connecting plate 707, the first connecting plate 707 is threadedly connected with a positioning bolt 7010, and the outside of the second guide rod 708 is provided with a plurality of threaded holes 709.

[0082] The method of use of this embodiment is as follows: connect the second lifting rope 203 to the drone (or use a hanger and the first fixing frame 20 for mounting, or use other lifting methods, as long as the method or method that can be thought of by those skilled in the art can be used for lifting the rack 10 in this embodiment);

[0083] Then, water is poured into the water tank 201, so that the weight on both sides of the frame 10 is balanced or nearly balanced (after the arc frame clamps the insulator string, the solenoid valve 205 is opened remotely to release the water), and then the frame 10 is lifted, so that the arc frame 60 is wrapped around both sides of the vertical insulator string;

[0084] The same principle applies, when the two arc-shaped frames 60 move toward each other, the third guide rod 1103 pushes the first mounting frame 110 to slide, so that the first mounting frame 110 drives the first abutting wheel 1101 to abut against the outside of the insulator;

[0085] At the same time, when the first mounting frame 110 slides, it will drive the rack 706 to slide outside the second guide rod 708. After the rack 706 contacts the second gear 703, it drives the second gear 703 to rotate. The second gear 703 drives the first gear 702 to rotate. The first gear 702 drives the rotating frame 70 to rotate through the pin shaft 701. The rotating frame 70 drives the top wheel 705 to rotate. The top wheel 705 resists the interference rod 801. The interference rod 801 drives the sliding rod 802 and the synchronous plate 804 to move upward. The synchronous plate 804 drives the positioning rod 805 to disengage from the insertion hole 905, so that the support swing arm 90 is no longer limited.

[0086] The support swing arm 90 rotates under the torsion force of the torsion spring 903, and then one end of the support swing arm 90 is clamped in the gap between two adjacent insulators and contacts the outside of the lower insulator.

[0087] Reference Figure 5 In this way, during the vertical upward climbing process, the support swing arm 90 can resist the insulator to support the frame 10, thereby further ensuring the walking stability of the frame 10. During the upward climbing process, under the torsion of the torsion spring 903, the support swing arm 90 will continue to be stuck in the gap between two adjacent insulators to further achieve support.

[0088] It should also be noted that in the first embodiment, when testing the insulator string in a horizontal state, it is not necessary to support the swing arm 90;

[0089] Therefore, it is only necessary to rotate the positioning bolt 7010, remove the positioning bolt 7010, and slide the adjustment rack 706 so that the rack 706 is located at the bottom of the third guide rod 1103, so that when the subsequent fixing plate 1104 slides and drives the rack 706 to slide, the rack 706 will not contact the second gear 703, and the positioning rod 805 cannot be separated from the socket 905. Therefore, when performing horizontal insulator string detection, the support swing arm 90 will not be stuck between two adjacent insulators.

[0090] In addition, the adjustment of the rack 706 has another function. When the diameter of the insulator string is small and the sliding distance of the fixed plate 1104 is long, the position of the rack 706 can be adjusted downward to allow the rack 706 to contact the second gear 703 later, so that the rack 706 can be engaged with the second gear 703 after the fixed plate 1104 has almost fully slid.

[0091] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0092] While the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that the scope of the present invention is defined by the appended claims and their equivalents.
