The cable lifting equipment for the power emergency repair tower includes: a bearing plate 1, on the bottom of which four Fulmar wheels distributed in a matrix are fixedly installed, and a push rod is fixedly installed on one side of its top to facilitate people to push the bearing plate 1. And a frame one 2 is arranged on the top of the bearing plate 1, and a lifting lead screw one 3 is rotatably installed therein. A motor one is fixedly installed on the top of the frame one 2, and its output shaft is fixedly connected to the top end of the lifting lead screw one 3. A lifting arm 4 is threadedly installed on the lifting lead screw one 3, and two vertical rods one are fixed in the frame one 2. Both of the two vertical rods one penetrate through the lifting arm 4 and are slidably connected thereto. And a frame two 5 is fixedly installed on one side of the lifting arm 4, and a rotating shaft 6 is rotatably installed on the top of the frame two 5. A motor two is fixedly installed in the frame two 5, and its output shaft is fixedly connected to the bottom end of the rotating shaft 6. A rotary table 7 is fixedly installed at the top end of the rotating shaft 6, and a plurality of wire boxes 8 distributed in an annular array are fixedly installed on the top of the rotary table 7. Different types of cables can be placed in different wire boxes 8 for repair personnel to select and use. And two C-shaped frames 14 are fixedly installed on the top of the bearing plate 1. Lifting lead screws two 15 are threadedly installed in both of the two C-shaped frames 14. Connecting arms 16 are threadedly installed on both of the two lifting lead screws two 15. Vertical rods two are fixed in both of the two C-shaped frames 14. The two vertical rods two respectively penetrate through the two connecting arms 16 and are slidably connected to the corresponding connecting arms 16. And one side of the two connecting arms 16 close to each other is fixedly connected to the frame one 2. Through the setting of the lifting lead screw one 3 and the lifting arm 4, the rotary table 7 can experience the first lift. Then, through the setting of the lifting lead screw two 15 and the connecting arm 16, the rotary table 7 can experience the second lift. The purpose of doing this is to be able to reduce the occupied space in terms of the overall height while lifting the rotary table 7 to a relatively high position. In the initial state, this device does not need to occupy too much space to prevent the limitation of the height limit pole on the road and ensure normal use.

[0025] In the above method, in order to be able to push the wire box 8 on the rotary table 7 to the front of the repair personnel to facilitate their access to the cable, a plurality of sliding openings 9 are opened on the rotary table 7. Sliding plates 10 are arranged in the plurality of sliding openings 9. The tops of the plurality of sliding plates 10 are respectively fixedly connected to the plurality of wire boxes 8. A plurality of electric push rods 11 are fixedly installed at the bottom of the rotary table 7. The output shafts of the plurality of electric push rods 11 are respectively fixedly connected to the plurality of sliding plates 10. And, a plurality of concave-shaped frames 12 are fixedly installed at the bottom of the rotary table 7. The plurality of electric push rods 11 respectively pass through the plurality of concave-shaped frames 12. And limiting rods 13 are slidably installed on the plurality of concave-shaped frames 12. One ends of the plurality of limiting rods 13 away from each other are respectively fixedly connected to the plurality of sliding plates 10. This can reduce the load on the output shafts of the electric push rods 11.

[0026] In this method, in order to improve the rotation stability of the rotating table 7, two support bars are fixedly installed on the rotating shaft 6, and a stabilizing rod is fixedly installed at the bottom of the two support bars. The bottom ends of the two stabilizing rods are both set to spherical surfaces, and the bottom ends of the two stabilizing rods are in contact with the frame 2 5.

[0027] In this method, in order to ensure that the two lifting screws 15 can rotate at the same time, the bottom ends of the two lifting screws 15 extend to the bottom of the supporting plate 1 and are movably connected to the supporting plate 1, and the two lifting screws 15 are fixedly sleeved with synchronous wheels, and the two synchronous wheels are sleeved with the same synchronous belt. A motor 3 is fixedly installed at the bottom of the supporting plate 1, and its output shaft and one of the lifting screws 15 are fixedly sleeved with gears, and the two gears are meshed.

[0028] The working principle of the cable lifting equipment for the power repair tower provided by the utility model is as follows:

[0029] When lifting the cables to a high place for emergency repair personnel to use, first place different types of cables in different wire boxes 8, then start the motor 1 in the positive direction, and its output shaft drives the lifting screw 1 3 to rotate, and the lifting arm 4 brings the frame 2 5 up;

[0030] After the lifting arm 4 rises to the highest point, the motor 3 is started in the positive direction. Through the meshing between the two gears, the corresponding lifting screw 2 15 can be driven to rotate the rod. At the same time, under the transmission mode of the synchronous wheel and the synchronous belt, the two connecting arms 16 will bring the frame 1 2 to rise as a whole. After the rotating table 7 rises to a suitable height, the motor 3 is turned off, and then the repair personnel start the motor 2 according to the required cable type. The output shaft of the motor drives the rotating shaft 6 and the rotating table 7 to rotate. When the designated wire box 8 rotates to the front of the repair personnel, the motor 2 is turned off, and then the output shaft of the corresponding electric push rod 11 is started to extend. The corresponding wire box 8 moves horizontally under the drive of the slide plate 10 and finally reaches the front of the repair personnel. Then the cables therein are taken out for laying and use.

[0031] After that, you can start the motor 2 and select and use it according to the needs during the laying process;

[0032] After the laying is completed, the above steps are reversed to bring the frame 1 2 back to contact with the carrier board 1 .

[0033] Compared with the related art, the cable lifting equipment for the power repair tower provided by the utility model has the following beneficial effects:

[0034] The utility model provides a cable lifting device for an electric power emergency repair tower. The cable can be lifted to a specified height for use by emergency repair personnel through a lifting arm 4 and a connecting arm 16 that can be lifted up and down.
