Description

Technical Field

[0001] This application relates to the field of cable maintenance and inspection equipment technology, specifically to a cable crawling conductive wheel arm for cable maintenance and inspection equipment. Background Technology

[0002] In power systems, as the coverage of high-voltage cables gradually expands, the demand for their maintenance and inspection is also increasing. Current maintenance methods primarily rely on manual high-altitude inspections, which involve the risks of working at height. To reduce these risks, the market is continuously developing inspection equipment capable of automatically crawling along high-voltage cables for inspection.

[0003] The crawling function of the inspection equipment is mainly accomplished by a crawling device at the bottom of the equipment. Since the equipment needs to be erected on cables for high-altitude operations, it is essential to ensure equipotential bonding between the equipment and the high-voltage lines. This involves transferring the high-voltage line potential to the equipment casing, making the current flowing through the equipment zero, thus fully guaranteeing the stability and safety of the inspection equipment on the cables. Previously, the applicant had applied for a high-voltage cable anti-detachment walking wheel device. Based on the principle of equipotential bonding, the applicant designed this crawling conductive wheel arm, further optimizing the structure of the original crawling device. This allows the inspection equipment to operate normally on live cables, much like a bird perched on a cable. The design is scientifically sound, reasonable, and highly practical. Utility Model Content

[0004] The purpose of this application is to provide a cable crawling conductive wheel arm for cable maintenance equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cable crawling conductive wheel arm for cable maintenance equipment includes a conductive metal support arm, on which a traveling wheel is rotatably mounted, and a motor for driving the traveling wheel to rotate is mounted on the conductive metal support arm. The outer circumferential surface of the traveling wheel is provided with a rubber wheel groove, and a conductive metal sheet is fixedly mounted on the conductive metal support arm. The end of the conductive metal sheet is provided with an elastic conductive part for contacting the cable.

[0007] As a further preferred embodiment of this utility model: the elastic conductive part is a conductive steel brush.

[0008] As a further preferred embodiment of this utility model: the conductive metal sheet is located on one side of the walking wheel, and the upper end of the conductive metal sheet is fixedly connected to the conductive metal support arm. When the walking wheel is hung on the cable, the conductive steel brush is located at the upper end of the cable and is always in contact with the cable.

[0009] As a further preferred embodiment of this utility model: swing arms are rotatably provided on both sides of the conductive metal support arm, and auxiliary pressure rollers are rotatably provided at the ends of the swing arms. An electric push rod for driving the swing arms to rotate is provided inside the conductive metal support arm.

[0010] As a further preferred embodiment of this utility model: the bottom of the electric push rod is rotatably connected to the conductive metal support arm, the top output end of the electric push rod is rotatably connected to a connecting rod, a rotating shaft is rotatably provided on the conductive metal support arm, the two ends of the rotating shaft are respectively fixedly connected to the swing arms on both sides, and the end of the connecting rod is fixedly connected to the rotating shaft.

[0011] Compared with the prior art, the beneficial effects of this application are:

[0012] This cable-crawling conductive wheel arm features rubber grooves on the inner side of the traveling wheels, increasing friction with the high-voltage cables and improving stability. Simultaneously, a conductive steel brush is designed to contact the cable, transferring the high-voltage cable potential to the conductive metal support arm and maintenance equipment. This ensures equipotential operation of the equipment on the high-voltage cables, guaranteeing safety and stability during maintenance. Furthermore, an auxiliary pressure roller presses the cable into the grooves of the traveling wheels, preventing it from detaching and ensuring stability. The design is scientifically sound, simple, innovative, and highly practical. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Example 1

[0022] Please see Figure 1-6 This application provides a technical solution: a cable crawling conductive wheel arm for cable maintenance equipment, including a conductive metal support arm 1, a traveling wheel 2 rotatably mounted on the conductive metal support arm 1, a motor 9 for driving the traveling wheel 2 to rotate on the conductive metal support arm 1, a rubber wheel groove 12 provided on the outer peripheral surface of the traveling wheel 2, the rubber wheel groove 12 can increase the stability of the traveling wheel 2 on the high-voltage cable 11, in order to transfer the potential on the high-voltage cable 11 to the conductive metal support arm 1 and the maintenance equipment 13, a conductive metal sheet 3 is fixedly mounted on the conductive metal support arm 1, and an elastic conductive part for contacting the cable is provided at the end of the conductive metal sheet 3. The elastic conductive part is a conductive steel brush 4, which is a metal wire brush that can be directly obtained by purchase. It can not only play a conductive role, but its good elastic deformation will not affect the movement of the traveling wheel 2 along the high-voltage cable 11. The design is scientific and reasonable.

[0023] Specifically, as a conventional technique familiar to those skilled in the art, the installation position of the conductive metal sheet 3 on the conductive metal support arm 1 should not affect the mounting of the traveling wheel 2 on the high-voltage cable 11. Therefore, as Figure 1 As shown, a conductive metal sheet 3 is placed on one side of the walking wheel 2, and the upper end of the conductive metal sheet 3 is fixedly connected to the conductive metal support arm 1, so that when the walking wheel 2 is hung on the cable, the conductive steel brush 4 is located at the upper end of the cable and is always in contact with the cable.

[0024] In addition, to prevent the high-voltage cable 11 from detaching from the bottom of the traveling wheel 2 and to further ensure the stability of the traveling wheel 2 on the high-voltage cable 11, swing arms 5 are rotatably mounted on both sides of the conductive metal support arm 1, and auxiliary pressure rollers 6 are rotatably mounted at the ends of the swing arms 5. An electric push rod 7 for driving the swing arms 5 to rotate is installed inside the conductive metal support arm 1. As a conventional technical means familiar to those skilled in the art, the electric push rod 7 utilizes the conventional crank-connecting rod mechanism principle to drive the swing arms 5. Specifically, as shown... Figure 4 As shown, the bottom of the electric push rod 7 is rotatably connected to the conductive metal support arm 1, and the top output end of the electric push rod 7 is rotatably connected to the connecting rod 10. A rotating shaft 8 is rotatably mounted on the conductive metal support arm 1, and the two ends of the rotating shaft 8 are fixedly connected to the swing arms 5 on both sides respectively. The end of the connecting rod 10 is fixedly connected to the rotating shaft 8.

[0025] Combination Figure 5 as well as Figure 6 As shown, to ensure the stability of the maintenance equipment 13 on the high-voltage cable, two crawling conductive wheel arms are usually installed on one maintenance equipment 13. That is, two walking wheels 2 drive one maintenance equipment 13 to run. The electrical components on the crawling conductive wheel arms are driven by the controller in the maintenance equipment 13. This is a conventional technical method and will not be described in detail. When the walking wheel 2 is hung on the high-voltage cable 11, the conductive steel brush 4 is also directly pressed against the surface of the high-voltage cable 11. This allows the potential of the high-voltage cable 11 to be transferred to the outer shell of the maintenance equipment 13 through the conductive steel brush 4, the conductive metal sheet 3, and the conductive metal support arm 1, achieving equipotential operation of the maintenance equipment 13 on the high-voltage cable 11. At the same time, when the walking wheel 2 is hung on the high-voltage cable 11, the electric push rod 7 will also drive the swing arm 5 to swing the auxiliary pressure wheel 6 to the lower end of the high-voltage cable 11. The auxiliary pressure wheel 6 then presses the high-voltage cable 11 into the rubber groove 12 of the walking wheel 2, preventing the high-voltage cable 11 from coming out of the groove and ensuring stability during movement.

[0026] During the movement, if an obstacle appears on the cable, the electric push rod 7 drives the swing arm 5 to swing downward, so that the auxiliary pressure roller 6 releases the clamping limit on the high-voltage cable 11. After the walking wheel 2 rolls over the cable obstacle, the auxiliary pressure roller 6 can be swung to the underside of the cable. As the conductive steel brush 4 has good elastic deformation ability, it can easily conform to the surface of the obstacle when passing through it, without affecting the walking wheel 2 when crossing the obstacle.

[0027] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application. Solutions or features that are prior art or common knowledge to those skilled in the art will not be described in detail in the above embodiments.

[0028] Furthermore, the technical solutions of this application are not limited to the above embodiments. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
