Description
Technical Field
[0001] This invention relates to the technical field of pole erection assistance devices, and in particular to a device for adjusting the angle of energized poles. Background Technology
[0002] As we all know, with the development of science and technology, people's demand for electrical energy is constantly increasing. Live-line work on distribution networks aims to ensure uninterrupted power supply to users and involves maintenance of distribution network equipment using methods such as live-line work and bypass work. In recent years, with the State Grid Corporation of China's vigorous promotion of a robust and smart grid, live-line work has developed significantly. Live-line work is increasingly welcomed by power grid operation and maintenance units due to its unparalleled advantages over outage work, such as improving power grid reliability, reducing power outage time, and increasing maintenance efficiency. Live-line work is an important branch of power technology, and its technical theories involve electric fields, magnetic fields, electrical engineering, electrical materials, power grid operation, electrical testing, overvoltage, mechanics, machinery, human physiology, and safety protection, making it a high-tech interdisciplinary field.
[0003] 10kV distribution lines are a crucial component of the power system and a construction project requiring high attention. Currently, in live-line work on 10kV distribution lines, the alignment of straight poles requires two ground electricians wearing insulated gloves to hold the pole. This process carries inherent risks; when the pole pit radius is too large, the ground electricians may be unable to reach the pole, and forcibly holding it risks falling into the pit, posing a serious threat to their safety and significantly prolonging the construction time. Therefore, exploring better ways to improve the safety of live-line work on 10kV distribution lines is extremely important, and a tool with sufficient lever arm, insulation strength, and mechanical strength is urgently needed. Live-line pole erection on 10kV is a technically demanding task, classified as a Category III live-line work project in the State Grid Corporation's project classification. Currently, few domestic enterprises are capable of performing this work, and collective enterprises have not yet developed tools that meet the above requirements. Summary of the Invention

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Please see Figure 1-4The present invention discloses an angle adjustment device for an electrified pole, comprising a pole 1, a base 2, a plurality of anchor bolts 3 evenly distributed on the base 2, and a rotary adjuster for adjusting the angle and verticality of the pole 1 around its central axis. The bottom of the pole 1 is provided with an arc-shaped groove 4 that fits into the anchor bolts 3. The rotary adjuster includes a fixed base 5, a geared disc 6 rotatably mounted on the fixed base 5, a first bearing seat 7 fixedly mounted on the geared disc 6, a first transmission shaft 8, a universal joint 9, a clamping and holding mechanism, a rotary driver providing power for the rotation of the geared disc 6, a second bearing seat 10 fixedly mounted on the fixed base 5, a second transmission shaft 11, and a rotary driver 12. A first sleeve 13 is rotatably mounted on a bearing housing 7, and a first drive shaft 8 is slidably mounted inside the first sleeve 13. A second sleeve 14 is rotatably mounted on a second bearing housing 10, and a second drive shaft 11 is slidably mounted inside the second sleeve 14. The first drive shaft 8 and the second drive shaft 11 are connected by a universal joint 9. A clamping and holding mechanism is fixedly mounted on the end of the first drive shaft 8, and a rotation driver 12 provides power for the rotation of the second sleeve 14. Furthermore, an anchor bolt 3 is inserted into an arc-shaped groove 4, and the center of the circle formed by multiple arc-shaped grooves 4 coincides with the central axis of the pole 1. The outer surfaces of the first drive shaft 8 and the second drive shaft 11 are... Multiple circumferentially arranged protruding slide rails are provided on the walls of both the first sleeve 13 and the second sleeve 14. Slide grooves that fit into the protruding slide rails are provided on the inner walls of both sleeves, and the protruding slide rails are slidably installed within the slide grooves. The rotary actuator can be a drive rod arranged radially along the drive gear 15, which drives the drive gear 15 to rotate by rotating the drive rod. The rotary actuator 12 is preferably a drive motor, and the output shaft of the drive motor is connected to the second sleeve 14. The rotary actuator 12 can also be other equivalent components that have a rotary driving effect on the second sleeve 14. The clamping and holding mechanism can be a clamp that clamps and holds the cylindrical component externally. In this embodiment... When adjusting the angle of pole 1, as the gear disc 6 rotates, the distance between the clamping and holding mechanism and the center of the gear disc 6 changes, while the first drive shaft 8 slides along the inner wall of the first sleeve 13 and the second drive shaft 11 moves from the second sleeve 14, thereby adaptively compensating for the aforementioned distance change. More specifically, during the verticality installation and adjustment of pole 1, the included angle between the first drive shaft 8 and the second drive shaft 11 is greater than 90° and less than or equal to 180°, and the first drive shaft 8 and the second drive shaft 11 are in a non-perpendicular state to ensure that the first drive shaft 8 and the second drive shaft 11 can be properly transmitted through the universal joint 9.
[0026] Specifically, the rotary actuator includes a drive gear 15 rotatably mounted on the fixed base 5 and meshing with the gear disk 6, and a brake motor 16 that provides power for the rotation of the drive gear 15. The output end of the brake motor 16 is fixedly connected to the drive gear 15. By starting the brake motor 16, the brake motor 16 drives the drive gear 15 to rotate, and the drive gear 15 drives the gear disk 6 to rotate, thereby realizing the rotational drive of the gear disk 6.
[0027] Specifically, the clamping and holding mechanism includes a mounting base 17 and clamping components arranged on the upper and lower parts of the mounting base 17. The clamping components include two grippers 18 hinged to the mounting base 17 and a first drive cylinder 19 that provides power for opening and closing the grippers 18. By activating the first drive cylinder 19, the first drive cylinder 19 can drive the corresponding grippers 18 to move away from each other or close, thereby achieving tight clamping and holding of the outer wall of the pole 1.
[0028] Specifically, it also includes two synchronizing rods 20 and synchronizing gears 21 fixedly installed on the synchronizing rods 20. The grippers 18 on the upper and lower parts of the mounting base 17 are synchronously connected through the synchronizing rods 20, and the synchronizing gears 21 on the two synchronizing rods 20 mesh with each other. Through the synchronizing rods 20 and the synchronizing gears 21, the two grippers 18 on the upper and lower parts of the mounting base 17 can be opened or closed synchronously, thereby improving the clamping stability of the pole 1.
[0029] Specifically, it also includes a clamping seat 22 that is slidably mounted on the mounting base 17. The clamping seat 22 is provided with two V-shaped locking teeth 23. The mounting base 17 is equipped with a second drive cylinder 24 that provides power for the feeding of the clamping seat 22. By activating the second drive cylinder 24, the clamping seat 22 moves closer to the pole 1 after transmission. The outer wall of the pole 1 is locked between the two locking teeth 23, which improves the clamping stability of the clamping claw 18 on the pole 1 and prevents relative movement between the pole 1 and the clamping claw 18 during the clamping process, thus ensuring the smooth progress of the pole 1 angle adjustment and vertical installation operation.
[0030] Specifically, the gripper 18 is equipped with anti-slip insulating teeth 25. Both the gripper teeth 23 and the anti-slip insulating teeth 25 are made of epoxy resin fiber material. Epoxy resin fiber material is lightweight, has high mechanical strength, and has good insulation properties, which prevents current from being directed to the angle adjustment device during live work, thereby improving the safety of the operation.
[0031] Specifically, it also includes a lifting drive platform 26, which is provided with a clearance opening 27; furthermore, the lifting drive platform 26 is preferably a scissor lift platform, but a hydraulic cylinder lift platform or other lifting drive mechanisms with equivalent lifting drive effect can also be used. The fixed seat 5 is fixedly installed on the lifting drive platform 26; through the lifting drive platform 26, the height of the fixed seat 5 can be adaptively adjusted, and the clamping point between the clamping and holding mechanism and the pole 1 can be adjusted. During the process of adjusting the angle or verticality of the pole 1, the pole 1 can be lifted as a whole, leaving a certain gap between the bottom of the pole 1 and the base 2 to reduce the friction between the pole 1 and the base 2. After the pole 1 is adjusted, the gap is filled in time with shims and then grouted with cement mortar to ensure the installation accuracy of the pole 1.
[0032] Specifically, an extension arm 28 is installed around the bottom of the lifting drive platform 26, and a hydraulic telescopic cylinder 29 is installed at the end of the extension arm 28 away from the lifting drive platform 26. By extending the extension arm 28 outward, the chassis of the lifting drive platform 26 is enlarged, and the hydraulic telescopic cylinder 29 contacts the ground, thereby improving the overall stability of the angle adjustment device.
[0033] Specifically, a bubble level 30 is provided on the top of the fixed base 5; the bubble level 30 can be used to assist in checking whether the fixed base 5 is level. When the ground is uneven, the levelness of the fixed base 5 can be adjusted by adjusting the extension length of each hydraulic telescopic cylinder 29, so as to further ensure the installation accuracy of the pole 1.
[0034] Specifically, the bottom of the lifting drive platform 26 is equipped with casters 31; the casters 31 allow the angle adjustment device to be moved as a whole, making it more convenient and labor-saving.
[0035] In use, push the lifting drive platform 26 to the pit above the installation location of pole 1. The extension arm 28 extends, and the output end of the hydraulic telescopic cylinder 29 extends and comes into contact with the ground. Observe the bubble level 30 until the fixed seat 5 is in a horizontal position. The clamping and holding mechanism tightly hugs the outer wall of pole 1. The rotary driver drives the gear plate 6 to rotate. After being transmitted through the first transmission shaft 8, the clamping and holding mechanism drives pole 1 to rotate, so that pole 1 rotates around its own central axis, thereby adaptively adjusting the rotation angle of pole 1. When it is necessary to adjust the verticality of pole 1, the fixed seat 5 is in a horizontal position, and the clamping and holding mechanism tightly hugs the outer wall of pole 1. By starting the rotary driver 12, the second sleeve 14 drives the second transmission shaft 11 to rotate. After being transmitted through the universal joint 9 and the first transmission shaft 8, the clamping and holding mechanism rotates around the central axis of the first transmission shaft 8, adaptively adjusting the inclination of pole 1.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
