The terms "disposed", "opened", "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, and an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal communication of two components.

[0050] High-voltage transmission lines typically consist of bundles of four or six cables. Each bundle requires insulating brackets installed at certain intervals, requiring workers to walk long distances along the lines. The upper cables are called upper cables, while the lower cables are called lower cables. To walk along a high-voltage transmission line, workers hold the upper cables with both hands and stand on the lower cables. However, this high-altitude walking is physically demanding, increasing work time and slowing down project progress.

[0051] To solve the above problems, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , an embodiment of the present application provides a top-driven high-altitude cable electric pulley vehicle, including a mounting seat 2, two pulleys 23 for supporting an upper cable 20 are provided below the mounting seat 2, an electric drive mechanism for driving the two pulleys 23 to roll on the upper cable 20 is provided on the mounting seat 2, and a downwardly extending vertical pole 11 is provided on the mounting seat 2, and the lower end of the vertical pole 11 is connected to a fixed pedal 13 located below the upper cable 20.

[0052] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4Two pulleys 23 are spaced apart and rotatably mounted on the bottom of the mounting base 2. Both pulleys 23 are simultaneously supported on the upper cable 20, not only bearing the load from the mounting base 2 but also allowing the pulleys 23 to roll on the upper cable 20. Because the outer circumference of the pulleys 23 is grooved, when the pulleys 23 are supported on the upper cable 20, the upper cable 20 lies within the groove, preventing the pulleys 23 from slipping off the upper cable 20 during rolling, thereby improving safety. For example, the pulleys 23 can be made of ABS engineering plastic. Using ABS engineering plastic increases the friction between the pulleys 23 and the upper cable 20, preventing the pulleys 23 from slipping on the upper cable 20 and ensuring stable force transmission under vertical loads, maintaining efficient force transmission. An electric drive mechanism is mounted on the mounting base 2 to provide power to drive the two pulleys 23 to roll on the upper cable 20. The vertical pole 11 is arranged vertically, the upper end of the vertical pole 11 is connected to one side of the mounting seat 2, and the lower end of the vertical pole 11 extends downward to just below the mounting seat 2. Exemplarily, the vertical pole 11 can be made of a steel pipe. For example, the vertical pole 11 can be made of a φ32×4 stainless steel pipe. The fixed pedal 13 is welded to the lower end of the vertical pole 11 and is used for the worker's feet to stand on to bear the worker's weight. Exemplarily, the fixed pedal 13 can be made of a steel plate. For example, the fixed pedal 13 is made of a 3mm thick stainless steel plate.

[0053] The top-driven overhead cable electric pulley provided in the embodiment of the present application is used to be installed on the upper cable 20 of the high-voltage transmission line to drive workers to move on the overhead cable, and then quickly move the workers to the work position for installation work; the specific installation operation process is as follows:

[0054] First, place two pulleys 23 on the upper cable 20 and connect the worker's safety rope to the safety ring on the upper cable 20; the safety ring can slide on the upper cable 20. Then, the worker holds the vertical pole 11 with one or both hands and stands on the fixed pedals 13. The electric drive mechanism is then activated, which drives the pulleys 23 to roll on the upper cable 20, moving the worker on the overhead cable. When the worker moves to the working position, the electric drive mechanism is turned off, the worker leaves the electric pulley and stands on the lower cable to install the insulation bracket. After the insulation bracket is installed, the worker is moved to the next working position by the electric pulley.

[0055] Compared with the prior art, the top-driven high-altitude cable electric pulley provided in the embodiment of the present application reduces the need for workers to walk long distances on the high-altitude cables, thereby reducing the workers' physical exertion, shortening working hours, and improving project progress.

[0056] In some embodiments, see Figure 1 、 Figure 2 , a mounting base safety ring 21 is provided on the mounting base 2. The mounting base safety ring 21 is a ring-shaped structure and is welded to the mounting base 2. When in use, the mounting base safety ring 21 is used to connect with the safety collar on the upper cable 20 through a safety rope to prevent the electric pulley from accidentally falling and improve safety.

[0057] The electric drive mechanism may include a motor mounted on the mounting base 2, which is simultaneously connected to the two pulleys 23 through a transmission mechanism to drive the two pulleys 23 to roll on the upper cable 20. The transmission mechanism may include a gear transmission mechanism, a chain transmission mechanism, a belt transmission mechanism, etc.

[0058] In some embodiments, see Figure 1 、 Figure 2 、 Figure 3 The electric drive mechanism includes a battery 3 and two motors 17 disposed on the mounting base 2. The battery 3 is connected to the two motors 17, and the two motors 17 are respectively connected to the two pulleys 23. For example, the battery 3 may include a 24V lithium battery, and the motors 17 may include 24V DC motors. The provision of two motors 17 can increase driving force. During use, the battery 3 is used to power the two motors 17, which in turn drive the two pulleys 23 to roll on the upper cable 20.

[0059] In some embodiments, see Figure 1 、 Figure 2 、 Figure 3 The output shaft of motor 17 is connected to a driving gear 5, and pulley 23 is connected to a driven gear 6 coaxially disposed therewith and meshing with driving gear 5. During operation, battery 3 is used to power both motors 17. Once powered, motor 17 drives driving gear 5, which in turn drives driven gear 6, which in turn drives the connected pulley 23 to roll on upper cable 20. Exemplarily, the transmission ratio between driving gear 5 and driven gear 6 is 1:4.

[0060] The driven gear 6 and the pulley 23 can be connected by fasteners such as bolts. Figure 2 、 Figure 3 The pulley 23 and the driven gear 6 connected thereto are an integrally formed structure. For example, the pulley 23 and the driven gear 6 connected thereto are made of ABS engineering plastic material.

[0061] In some embodiments, see Figure 1 、 Figure 2 、 Figure 3, the mounting base 2 has a mounting cavity, and the battery 3 is arranged in the mounting cavity. By arranging the battery 3 in the mounting cavity of the mounting base 2, physical protection is provided for the battery 3 to prevent external impact, extrusion or puncture, thereby improving the safety of the battery 3. Exemplarily, the mounting base 2 can be made of steel plate; for example, the mounting base 2 can include a mounting box made of a 3mm thick stainless steel plate, and the battery 3 is arranged in the mounting box. In order to facilitate the inspection and replacement of the battery 3 in the mounting base 2, the mounting base 2 has a cover plate 1 for opening and closing the mounting cavity. Exemplarily, the cover plate 1 is arranged on the top of the mounting base 2.

[0062] In some embodiments, see Figure 1 、 Figure 2 、 Figure 3 A main support plate 9 and a secondary support plate 14 are connected to the bottom of the mounting seat 2. Two pulley shafts 7 are connected between the main support plate 9 and the secondary support plate 14. Two pulleys 23 are rotatably mounted on the two pulley shafts 7 respectively.

[0063] Exemplarily, the main support plate 9 and the auxiliary support plate 14 are arranged vertically and in parallel; the upper ends of the main support plate 9 and the auxiliary support plate 14 are respectively welded to the bottom of the mounting base 2, and the two pulley shafts 7 are arranged in parallel, and their two ends are respectively connected to the main support plate 9 and the auxiliary support plate 14; in the direction of extension of the upper cable 20, a guard plate 4 is also connected between the two ends of the main support plate 9 and the auxiliary support plate 14; the pulley 23 is installed on the pulley shaft 7 through two bearings 15 so that the pulley 23 can rotate around the pulley shaft 7; the motor 17 can be installed on the main support plate 9 or the auxiliary support plate 14.

[0064] In some embodiments, the driven gear 6 is disposed adjacent to the main support plate 9, the motor 17 is mounted on the main support plate 9, the driving gear 5 is disposed above the driven gear 6, and the lower end of the main support plate 9 has a bent portion extending to directly below the driven gear 6. The bent portion is provided to protect the driven gear 6.

[0065] In some embodiments, see Figure 2 Two retaining rings 16 are sleeved on the pulley shaft 7, one of which is located between the main support plate 9 and the pulley 23, and the other is located between the auxiliary support plate 14 and the pulley 23. The retaining rings 16 not only fix the position of the pulley 23 on the pulley shaft 7 to prevent axial displacement due to vibration or movement, but also reduce direct contact between the pulley 23 and the main support plate 9 and the auxiliary support plate 14, thereby reducing wear and extending the service life of the components.

[0066] In some embodiments, see Figure 2, a handle 10 is provided on the vertical pole 11. By providing the handle 10, it is convenient for workers to hold it. For example, the handle 10 can be made of a φ32×4 stainless steel pipe, and the handle 10 is welded to the vertical pole 11. In order to facilitate workers to control the start and stop of the motor 17, see Figure 1 The motor control switch 22 for controlling the start and stop of the motor 17 is set on the mounting base 2.

[0067] The upper end of the vertical rod 11 can be directly welded to the mounting base 2. In some embodiments, see Figure 3 , also includes a bolt 8, a fixing pull ring 18 and a nut 19. The bolt 8 passes through the secondary support plate 14, the main support plate 9 and the fixing pull ring 18 in sequence and is connected to the nut 19. The upper end of the vertical pole 11 is connected to the fixing pull ring 18.

[0068] The lower end of the upright 11 can be directly welded to the fixed pedal 13. In some embodiments, see Figure 1 The lower end of the upright 11 is welded to the fixed pedal 13 via a fixed plate 12. For example, the fixed plate 12 can be made of a 3 mm thick stainless steel plate.

[0069] See also Figure 4 The top of the fixed pedal 13 has a standing area Z, a fixed area, and a standing area Y. Standing areas Z and Y are located on either side of the fixed area, and the fixing plate 12 is welded to the fixed area. During use, a worker's feet stand on standing areas Z and Y, respectively. For example, two pulleys 23 are located directly above standing areas Z and Y, respectively.

[0070] The above is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Based on the technical essence of the present application and within the spirit and principles of the present application, any simple modification, equivalent replacement and improvement of the above embodiment shall still fall within the scope of protection of the technical solution of the present application.
