[0042] The counterweight assembly includes a first rack 3, which is fixedly mounted on a side of the screw sleeve 24 away from the first fixed block 27, a gear 31 is meshed above the side of the first rack 3 away from the screw sleeve 24, a second rack 32 is meshed on the side of the gear 31 away from the first rack 3, and a second limit block 33 is fixedly mounted below the side of the second rack 32 away from the gear 31;

[0045] Specifically, when in use, the staff needs to stand in the bearing frame 28, and then start the installation slot 11 to drive the first rotating wheel 2 to rotate, so that the first rotating wheel 2 drives the transmission belt 21, and the transmission belt 21 can drive the second rotating wheel 22 to rotate, so that the lead screw 23 can rotate, and the lead screw 23 can drive the screw sleeve 24, so that the screw sleeve 24 rises to the substation equipment, so that it can be flexibly adjusted according to the substation equipment at different heights to adapt to different maintenance heights;

[0046] Furthermore, when the screw sleeve 24 rises, it can drive the first rack 3 to rise, and the first rack 3 can drive the gear 31 to rotate, so that the gear 31 drives the second rack 32 to descend, and the second rack 32 can drive the first counterweight block 35 to descend, so that the overall center of gravity of the equipment is lowered and the stability of the equipment is improved.

[0047] Example 2: Please refer to Figures 1 to 5 An extension component is provided on the base 1, and the extension component includes an extension plate 4. There are two extension plates 4, which are distributed on the front and rear sides of the base 1, and the extension plates 4 are in active contact with the base 1. An elastic column 41 is fixedly installed inside the base 1, and both ends of the elastic column 41 are fixedly connected to the two extension plates 4 respectively;

[0048] A follower 42 is fixedly mounted on the upper surface of the extension plate 4, and a fourth driving groove 43 adapted to the follower 42 is formed on the surface of the base 1;

[0049] There is a distance between the two followers 42 , and the distance is located directly below the first counterweight 35 , and the first counterweight 35 is in a triangular shape.

[0050] On the basis of Example 1, when the carrying frame 28 continuously approaches the upper end of the housing 26, the first counterweight block 35 gradually descends until the first counterweight block 35 contacts the follower 42 and drives the follower 42, so that the two followers 42 move to the two sides of the base 1, thereby increasing the bottom positioning area of ​​the device and further improving the stability of the device;

[0051] When the supporting frame 28 rises to the upper end of the outer shell 26 or approaches the upper end, the first rack 3 will pass through the through slot 37 and extend to the outside of the outer shell 26. At this time, the staff is also at a high place and can tie one end of the safety rope around the waist and the other end to the surface of the first rack 3 on the outside of the outer shell 26 to improve the safety of the staff when working at a high place.

[0052] Example 3: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 A support assembly is provided on the second limit block 33, and the support assembly includes a first mounting frame 5, the first mounting frame 5 is fixedly mounted on the bottom of the second limit block 33, a first rotating shaft 51 is fixedly mounted inside the first mounting frame 5, and one end of the first rotating shaft 51 passes through the first mounting frame 5 and extends to the outside of the first mounting frame 5, a surface of the first rotating shaft 51 on the outside of the first mounting frame 5 is provided with a thread, and a surface of the first rotating shaft 51 on the outside of the first mounting frame 5 is threadedly connected with a first nut 52;

[0053] A support leg 53 is movably mounted on the outer surface of the first rotating shaft 51, and the connection between the support leg 53 and the first rotating shaft 51 is located on the inner side of the first mounting frame 5. A universal wheel set 54 is fixedly mounted on one end of the support leg 53 away from the first mounting frame 5. A second fixing block 55 is fixedly mounted on the surface of the housing 26, and an electric push rod 56 is fixedly mounted on the middle part of the second fixing block 55. A thread is formed on the outer surface of the output end of the electric push rod 56, and a second nut 57 is threadedly connected to the outer surface of the output end of the electric push rod 56.

[0054] A second mounting frame 58 is fixedly mounted on the universal wheel assembly 54, a second rotating shaft 59 is fixedly mounted inside the second mounting frame 58, one end of the second rotating shaft 59 passes through the second mounting frame 58 and extends to the outside of the second mounting frame 58, a thread is formed on the surface of the second rotating shaft 59 outside the second mounting frame 58, and a third nut 510 is threadedly connected to the surface of the second rotating shaft 59 outside the second mounting frame 58;

[0055] A first support member 511 is movably mounted on the outer surface of the second rotating shaft 59, and the connection between the first support member 511 and the second rotating shaft 59 is located on the inner side of the second mounting frame 58. A second support member 512 is movably mounted on one end of the first support member 511 away from the second mounting frame 58. A fastening groove 513 is formed on one end of the second support member 512 away from the first support member 511. The output end of the electric push rod 56 is located in the fastening groove 513, and the width of the fastening groove 513 is smaller than the width of the second nut 57.

[0056] The first support member 511 and the second support member 512 are both provided with threaded holes on their surfaces, and the number of threaded holes is greater than one. The first support member 511 and the second support member 512 are provided with fixing members 514 on their surfaces. The first support member 511 and the second support member 512 are both threadedly connected with fixing bolts 515 on their surfaces. The fixing members 514 fix the first support member 511 and the second support member 512 together through the fixing bolts 515.

[0057] When the base 1 and the universal wheel set 54 are in contact with the ground, an angle exists between the support leg 53 and the housing 26 .

[0058] On the one hand, when the device is moving, it is necessary to start the electric push rod 56 to drive the second support member 512 and the first support member 511 to move, so that the second support member 512 and the first support member 511 drive the universal wheel group 54 to move toward the base 1. At this time, the angle between the support leg 53 and the housing 26 becomes smaller, the base 1 is separated from the ground, and only the universal wheel group 54 is in contact with the ground, so that the device can be flexibly moved;

[0059] On the other hand, when the device is not in use, it is necessary to loosen the second nut 57, then loosen the fixing bolt 515, remove the fixing member 514, bend the second support member 512 downward so that the second support member 512 contacts the ground, increase the support angle, and then use other threaded holes and fixing bolts 515 to fix the fixing member 514 on the first support member 511 and the second support member 512 to prevent the first support member 511 and the second support member 512 from moving freely. This can improve the stability of the device when the device is stationary, such as the attached Figure 1 As shown;

[0060] On the basis of Example 1, when the second rack 32 descends, the second limit block 33 is driven to descend, so that the second limit block 33 drives the first installation frame 5 to descend, so that the angle between the support leg 53 and the shell 26 becomes larger, and then, by tightening the first nut 52, the first nut 52 is in close contact with the first installation frame 5, and the friction between the first nut 52 and the first installation frame 5 is used to limit the support leg 53 to prevent the support leg 53 from rotating at will, so that the support leg 53, the ground and the shell 26 form a triangle, which can further improve the stability of the device;

[0061] On the basis of Example 2, when the height of the supporting frame 28 does not approach the top of the outer shell 26, the first counterweight block 35 may not be able to contact the follower 42, making it difficult to expand, affecting the stability of the equipment. At this time, the third nut 510, the second nut 57 and the fixing bolt 515 can be loosened, and the first support member 511 and the second support member 512 can be rotated to make the second support member 512 contact the ground, and then the third nut 510 is tightened, and the fixing bolt 515 fixes the fixing member 514 on the first support member 511 and the second support member 512, and the first support member 511 and the second support member 512 are positioned, thereby expanding the support range of the side of the equipment, improving the stability of the equipment, and reducing the impact of the inability of the extension plate 4 to expand on the stability of the equipment.

[0062] Example 4: Please refer to Figure 1 , Figure 2 and Fig. 9 The first tool box 210 is provided with a delivery assembly, which includes a carrying plate 6, which is fixedly mounted on the surface of the first tool box 210, a mounting member 61 is fixedly mounted on the bottom of the carrying plate 6, and a second servo motor 62 is fixedly mounted on the surface of the mounting member 61;

[0063] A first sprocket 63 is fixedly mounted on the output shaft of the second servo motor 62, a chain 64 is drivingly connected to the outer surface of the first sprocket 63, a second sprocket 65 is drivingly connected to the side of the chain 64 away from the first sprocket 63, a second tool box 66 is fixedly mounted below one side of the chain 64, and a second counterweight 67 is fixedly mounted above the side of the chain 64 away from the second tool box 66;

[0064] The first sprocket 63 is movably mounted on the surface of the carrying plate 6 , and the second sprocket 65 is movably mounted on the surface of the first tool box 210 .

[0065] On the basis of Example 2, when the carrying frame 28 approaches or reaches the top of the housing 26, the first tool box 210 can be conveniently used to place tools. When the carrying frame 28 is located close to the middle of the housing 26, the first tool box 210 is difficult to use. The second servo motor 62 can be started to drive the first sprocket 63 to rotate, so that the first sprocket 63 drives the chain 64, so that the second tool box 66 is raised to the maintenance position, which can facilitate the staff to place tools.

[0066] Furthermore, the second tool box 66 can be used to store tools on one hand, and on the other hand, it is convenient for other staff to deliver tools or new parts to the maintenance staff, thereby improving the convenience of the equipment;

[0067] Furthermore, when the supporting frame 28 approaches the middle of the outer shell 26, the extension plate 4 cannot be expanded. By raising the second tool box 66 to the maintenance position, the second counterweight block 67 will drop, and the center of gravity of the equipment will be adjusted again, making the center of gravity of the equipment lower, thereby further improving the stability of the equipment.

[0068] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
