Description

Technical Field

[0001] This invention relates to the field of power transmission line maintenance technology, and more specifically, to a lifting device for distribution network lines. Background Technology

[0002] With the continuous development of the social economy, the coverage of power distribution network construction is also gradually expanding. However, due to the long operating time and disrepair of some lines, the persistently low winter temperatures in the region, and extreme weather conditions (such as lightning strikes), mechanical damage, insulation flashover, electrical breakdown, and conductors coming out of the insulator slots of straight poles occur frequently.

[0003] Currently, the main methods used for replacing insulators on energized straight poles of distribution network lines and handling faults such as live conductors coming out of the insulator slots on straight poles are to use the small boom of an insulated bucket truck to lift the live conductor to a suitable position before replacing the insulator. In addition, the small boom of the insulated bucket truck is used to lift the conductor and place it into the insulator slot.

[0004] However, due to its own size, the insulated bucket truck often has difficulty moving the small boom to the working position during the above-mentioned operation. In addition, the small boom needs to be dismantled and installed during the operation of the insulated bucket truck. The small boom is usually too big, which makes the operation cumbersome and reduces the efficiency of the operation. Summary of the Invention

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the following will be described in conjunction with the appendix. Figure 1-4 The embodiments of the present invention will be described in further detail below.

[0022] This application provides a lifting device for a power distribution network line, such as... Figure 1 and Figure 2 As shown, it includes a telescopic support rod 1, a driving component 2, a gripper 4, a fixing component 6, and an inclined support component 7.

[0023] The telescopic support rod 1 mainly includes a main rod 11, a secondary rod 12, and a threaded rod 13. The main rod 11 has an internally hollow tubular structure and is sleeved on the secondary rod 12, and the secondary rod 12 can move axially relative to the main rod 11. The threaded rod 13 is located inside the main rod 11, and the centerlines of the threaded rod 13, the main rod 11, and the secondary rod 12 coincide, and the threaded rod 13 is threadedly connected to the secondary rod 12.

[0024] An operating box is fixedly connected to the bottom end of the main rod 11. The driving component 2 is located inside the operating box and can be used to drive the threaded rod 13 to rotate.

[0025] The drive unit 2 includes a servo motor 21 and a controller. Both the controller and the servo motor 21 are installed inside the operating box. The output shaft of the servo motor 21 is fixedly connected to the threaded rod 13. The control terminal of the controller is electrically connected to the control terminal of the servo motor 21. An operating interface is provided on the operating box, and there is a wired connection between the operating interface and the controller. The user can input control commands to the controller through the operating interface to make the controller control the servo motor 21. In addition, the controller is also equipped with a wireless communication module, which can wirelessly communicate with the remote control, so that the user can input control commands to the controller through the remote control.

[0026] In this application, the gripper 4 is used to cooperate with the transmission line, and the fixing member 6 is used to fix the main rod 11 to the crossarm of the insulator on the straight rod. Therefore, in this application, during the replacement or maintenance of the insulator, the user only needs to first clamp the transmission line with the gripper 4, and then fix the main rod 11 to the crossarm with the fixing member 6. Then, the user can send control commands to the controller through the operation interface or remote control to make the servo motor 21 work. At this time, the output shaft of the servo motor 21 drives the threaded rod 13 to rotate. The rotation of the threaded rod 13 causes the auxiliary rod 12 to move away from or closer to the operation box, so as to facilitate the support of the transmission line to detach from the insulator, thereby facilitating the replacement or maintenance of the insulator on the straight rod.

[0027] like Figure 3 As shown, the gripper 4 includes a rotating plate 41, a first side plate 42, a second side plate 43, a fixing bar 44, and a locking member 5.

[0028] The bottom side of the rotating plate 41 is fixedly connected to the end of the auxiliary rod 12 away from the control box. The first side plate 42 and the second side plate 43 are both fixedly connected to the top side of the rotating plate 41. The first side plate 42 has a first groove, and the second side plate 43 has a second groove. The fixing clip 44 has a U-shaped strip structure, and one end of the fixing clip 44 is rotatably connected to the inner wall of the first groove on the first side plate 42. The other end of the fixing clip 44 can cooperate with the second groove on the second side plate 43. The mating strip block 45 is fixedly connected to the rotating plate 41, and the fixing clip 44, the first side plate 42, the second side plate 43, and the mating strip block 45 on the rotating plate 41 form a closed rectangular hole. The power transmission line passes through the rectangular hole formed by the fixing clip 44, the first side plate 42, the second side plate 43, and the mating strip block 45.

[0029] A first roller 56 is rotatably connected to the fixing clip 44, and a second roller 57 is rotatably connected between the first side plate 42 and the second side plate 43. The power transmission line passes through the gap between the first roller 56 and the second roller 57. A locking member 5 is provided on the second side plate 43 to restrict the rotation of the fixing clip 44.

[0030] The locking component 5 includes a first abutment block 51, a locking strip 52, a second abutment block 53, and a spring 55. Two ear plates 54 are fixedly connected to the second side plate 43, and the locking strip 52 is located between the two ear plates 54 and is rotatably connected to the two ear plates 54.

[0031] The first abutment block 51 is integrally formed with the fixing strip 44. The bottom side of the first abutment block 51 has an inclined surface, and the inclined surface on the first abutment block 51 is inclined downward in the vertical direction. The second abutment block 53 is integrally formed with the locking member 5. The top side of the second abutment block 53 has an inclined surface, and the inclined surface on the second abutment block 53 is inclined downward in the vertical direction. The top side of the first abutment block 51 abuts against the bottom side of the second abutment block 53.

[0032] One end of the spring 55 is fixedly connected to the second side plate 43, and the other end of the spring 55 is fixedly connected to the locking strip 52. The spring 55 is located below the two ear plates 54. When the power transmission line is located between the first side plate 42 and the second side plate 43, simply rotate the fixing clip 44. After the first abutment block 51 and the second abutment block 53 come into contact, the first abutment block 51 can push the second abutment block 53 to rotate under the action of the inclined surfaces of the first abutment block 51 and the second abutment block 53. At this time, the spring 55 is compressed. After the first abutment block 51 moves to the bottom of the second abutment block 53, the locking strip 52 is reset under the elastic force of the spring 55. At this time, the bottom side of the second abutment block 53 abuts against the top side of the first abutment block 51, thereby restricting the rotation of the fixing clip 44.

[0033] like Figure 4 As shown, the fixing component 6 includes a first sleeve 61, a U-shaped frame 62, a clamping plate 63, a limiting strip 64, and a pushing screw 65. The first sleeve 61 is rotatably connected to the main rod 11, and the U-shaped frame 62 is fixedly connected to the first sleeve 61. The U-shaped frame 62 includes a bottom side plate, a top side plate, and a vertical side plate. The length of the top side plate of the U-shaped frame 62 is greater than that of the bottom side plate of the U-shaped frame 62. A hook body is also integrally formed on the top side plate of the U-shaped frame 62.

[0034] The limiting strip 64 and the U-shaped frame 62 are integrally formed. The clamping plate 63 is installed in the U-shaped frame 62. The clamping plate 63 is slidably connected to the limiting strip 64, and the clamping plate 63 can move vertically in the U-shaped frame 62.

[0035] The end of the push screw 65 passes through the bottom side plate of the U-shaped frame 62 and is rotatably connected to the clamping plate 63. The push screw 65 is threadedly connected to the bottom side plate of the U-shaped frame 62. The clamping plate 63 and the top side plate of the U-shaped frame 62 abut against the crossarm on the straight rod used for installing insulators.

[0036] In this application, the U-shaped frame 62 is moved so that the crossarm passes through it. Then, the push screw 65 is rotated, causing the clamping plate 63 to move, so that both the clamping plate 63 and the top side plate of the U-shaped frame 62 abut against the crossarm on the straight rod used for installing insulators, thereby fixing the U-shaped frame 62 to the crossarm, and thus fixing the main rod 11 to the crossarm.

[0037] like Figure 1 and Figure 2 As shown, the inclined support 7 includes a rotating support rod 71, a second sleeve 72, a push ring 73, and a connecting block 74. The second sleeve 72 is sleeved on the main rod 11 and can slide along the axial direction of the main rod 11.

[0038] One end of the rotating support rod 71 is hinged to the second sleeve 72, and the other end of the rotating support rod 71 is fixedly connected to the rotating plate 41. The axis of the rotating support rod 71 is inclined relative to the axis of the main rod 11.

[0039] A slotted groove 14 is formed on the main rod 11. A push ring 73 is located inside the main rod 11 and slides axially along the main rod 11. The push ring 73 is threadedly connected to the threaded rod 13. A connecting block 74 passes through the slotted groove 14, and one end of the connecting block 74 is fixedly connected to the push ring 73, while the other end of the connecting block 74 is fixedly connected to the second sleeve 72.

[0040] During the rotation of the threaded rod 13, the rotation of the threaded rod 13 drives the push ring 73 to move. The movement of the push ring 73 drives the connecting block 74, the second sleeve 72 and the rotating support rod 71 to move, so that the rotating support rod 71 and the auxiliary rod 12 can move synchronously. At the same time, under the action of the rotating support rod 71, the auxiliary rod 12 is restricted from rotating relative to the main rod 11.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.

[0042] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
