Description

Technical Field

[0002] In the power industry, power equipment maintenance usually includes regular inspection, cleaning, maintenance and testing to ensure that the equipment is in good operating condition. This may involve inspecting the appearance of the equipment to see if there are signs of damage, corrosion or overheating, cleaning the equipment to remove dust, dirt and debris to prevent it from affecting heat dissipation and insulation performance, lubricating and tightening key components, and measuring and analyzing electrical parameters. Power equipment maintenance requires lifting equipment for lifting and installation; Lifting is a very important link, because power equipment is usually large in size and heavy in weight, and professional equipment and technology are needed to carry out lifting operations. Before carrying out lifting operations, detailed planning and preparation are required, including determining the lifting plan, selecting appropriate lifting equipment, checking the working status of the lifting equipment, formulating safety measures, etc. Only by doing these preparations can we ensure the smooth progress of the lifting operation, avoid accidents, and ensure the safe installation, maintenance and operation of power equipment.

[0003] In power maintenance, power equipment is generally hoisted by the boom of the hoisting equipment for installation and disassembly. For example, in the application No. CN202411014300.5, a hoisting equipment for power equipment maintenance and repair is provided. Through the coordinated setting of the main cantilever and the auxiliary cantilever, the cantilever can be adjusted to different degrees according to the lifting height and lifting distance by means of its own extension and shortening, and the angle between the main cantilever and the auxiliary cantilever can be bent and adjusted according to the different use environments, so that the lifting mechanism can be extended into the use environment with a certain angle. However, this kind of hoisting equipment for power equipment maintenance and repair has the following technical defects: when the boom moves horizontally and rotates laterally for the hoisting equipment, the moving distance and the rotation angle are large, which makes it difficult to accurately align the power equipment with the preset installation position when installing the power equipment. Fine-tuning needs to be performed by other equipment or manually, and the operation is cumbersome, and there is a high risk of manual fine-tuning.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1 - Figure 5As shown, a lifting mechanism for equipment for power maintenance includes a cantilever 1. The cantilever 1 is an existing structure and will not be described in detail herein. The lower surface of the left end of the cantilever 1 is connected to a lifting platform 3 through a connecting column 2. A hydraulic cylinder 4 is arranged on the upper surface of the lifting platform 3, and the hydraulic cylinder 4 is arranged on the rear side of the connecting column 2. The lower end of the hydraulic cylinder 4 passes through the upper part of the lifting platform 3 and is fixedly connected to a C-shaped lifting plate 5. In addition, the upper surface of the C-shaped lifting plate 5 is at a certain distance from the inner top wall of the lifting platform 3, providing a moving space for the C-shaped lifting plate 5 to move upward. The upper surface of the lifting platform 3 is provided with a servo The servo motor 6 is arranged on the right side of the connecting column 2. The power output end of the servo motor 6 is connected to the motor shaft 7 through a coupling transmission. The interior of the motor shaft 7 is connected to the rotating shaft 10 through a cross connecting block 9. A cross movable groove 8 is provided inside the lower end of the motor shaft 7. The cross connecting block 9 is plugged into the interior of the cross movable groove 8. The setting of the cross movable groove 8 provides a movable space for the cross connecting block 9, so that the cross connecting block 9 can move smoothly in the vertical direction. The setting of the cross connecting block 9 can connect the motor shaft 7 with the The rotating shaft 10 is connected together so that the rotating shaft 10 can move vertically on the motor shaft 7 without affecting the rotation of the rotating shaft 10 driven by the motor shaft 7. The circumferential surface of the lower end of the rotating shaft 10 is provided with a rotating spur gear 11. The left end of the rotating spur gear 11 is meshed and connected with a driven spur gear 12. The rear ends of the rotating spur gear 11 and the driven spur gear 12 are both arranged inside the front end of the C-shaped lifting plate 5, and the upper and lower ends of the rear sides of the rotating spur gear 11 and the driven spur gear 12 are both abutted against the front end of the C-shaped lifting plate 5 through a rotating ball. The arrangement of the beads enables the rotating spur gear 11 and the driven spur gear 12 to be installed inside the C-shaped lifting plate 5 without affecting the rotation of the rotating spur gear 11 and the driven spur gear 12. When the C-shaped lifting plate 5 moves in the vertical direction, the rotating spur gear 11 and the driven spur gear 12 can be driven to move in the vertical direction at the same time, so that the rotating spur gear 11 and the driven spur gear 12 are always in a meshing state. Then, when the servo motor 6 drives the rotating spur gear 11 to rotate, the rotating spur gear 11 can always drive the driven spur gear 12 to rotate. A rotating shaft 2 13 is provided in the middle of the driven spur gear 12, and a bevel gear 14 is provided at the lower end of the rotating shaft 2 13. A bevel gear 15 is meshedly connected to the left side of the bevel gear 14. Threaded rods 16 are provided on the left and right sides of the bevel gear 2 15. The circumferential surfaces of the two threaded rods 16 are threadedly connected with moving blocks 17. A hanging plate 18 is provided on the lower surface of the moving block 17, and the edge of the upper surface of the hanging plate 18 abuts against the lower surface of the hanging platform 3, so that the hanging plate 18 will not be affected by the hanging platform 3 when it moves horizontally or rotates, and can smoothly move horizontally or rotate. The arrangement of the two moving blocks 17 and the two threaded rods 16 makes the left and right sides of the hanging plate 18 have the same force, so that the two moving blocks 17 can share the same weight, thereby making the hanging plate 18 more stable when hanging power equipment. A hook 19 is provided on the lower surface of the hanging plate 18, and the outer walls of the left and right ends of the hanging plate 18 are provided with mounting blocks 32. The upper edges of the two mounting blocks 32 The upper part of the two L-shaped supporting movable rods 33 is respectively inserted into the inner part of the two movable through grooves 34. The setting of the movable through grooves 34 provides the L-shaped supporting movable rod 33 with a movable space, and at the same time limits the L-shaped supporting movable rod 33, so that the L-shaped supporting movable rod 33 can smoothly move horizontally left and right, and can provide support for the hanging plate 18 without affecting the lateral rotation or movement of the hanging plate 18; It should be noted that the mounting block 32 and the L-shaped supporting movable rod 33 are all on the same horizontal plane as the threaded rod 16 and the moving block 17, so that when the threaded rod 16 rotates, the moving block 17 drives the hanging plate 18 and the mounting block 32 and the L-shaped supporting movable rod 33 to move horizontally in the same direction, thereby avoiding the mounting block 32 and the L-shaped supporting movable rod 33 from being offset and stuck, and the distance between the vertical part of the L-shaped supporting movable rod 33 and the outer wall of the hanging platform 3 is the same as the limit distance of the horizontal movement of the moving block 17, that is, after the moving block 17 moves to the left or right to the limit distance, the vertical part of the L-shaped supporting movable rod 33 will not touch the outer wall of the hanging platform 3, thereby avoiding the L-shaped supporting movable rod 33 from contacting the outer wall of the hanging platform 3 and causing When the hanging plate 18 drives the L-shaped supporting movable rod 33 to rotate, the L-shaped supporting movable rod 33 is damaged by friction with the outer wall of the hanging platform 3, affecting the limiting supporting effect of the L-shaped supporting movable rod 33 on the hanging platform 3. Then, through the setting of the top rotating plate 31, because the top rotating plate 31 is rotatably installed on the hanging platform 3, when the hanging plate 18 rotates horizontally, it can drive the top rotating plate 31 to rotate horizontally synchronously through the mounting block 32 and the L-shaped supporting movable rod 33, so that no matter how the hanging plate 18 rotates, the mounting block 32 and the L-shaped supporting movable rod 33 are always on the same horizontal plane with the threaded rod 16 and the moving block 17, and then the mounting block 32 and the L-shaped supporting movable rod 33 can be synchronously moved horizontally with the moving block 17.

[0021] An annular groove 25 is provided on the inner side wall of the lower end of the hoisting platform 3, and rotating blocks 27 are movably installed inside the left and right sides of the annular groove 25. The setting of the annular groove 25 provides a movable space for the rotating blocks 27, so that the rotating blocks 27 can smoothly rotate horizontally. The ends of the two threaded rods 16 away from the bevel gear 15 are rotatably installed inside the two rotating blocks 27. The setting of the rotating blocks 27 can limit the threaded rods 16 without affecting the rotation of the threaded rods 16. The threads on the surfaces of the two threaded rods 16 have the same rotation direction. The threads with the same rotation direction enable the two rotating blocks 27 on their surfaces to move in the same direction when the two threaded rods 16 rotate synchronously, thereby driving the hoisting plate 18 to stably move horizontally. The inner side wall of the upper end of the hoisting platform 3 is provided with an annular groove 26, and a transverse rotating plate 21 is movably installed inside the annular groove 26. The setting of the annular groove 26 can limit the transverse rotating plate 21 without affecting the rotation of the transverse rotating plate 21. The transverse rotating plate 21 is set between the driven spur gear 12 and the bevel gear 14, and there is a certain gap between the upper surface of the transverse rotating plate 21 and the lower surface of the C-shaped lifting plate 5, that is, the hydraulic cylinder 4 drives the C-shaped lifting plate 5 to move downward, so that the bevel gear 14 and the bevel gear 2 15 When meshing, the transverse rotating plate 21 will not contact the C-type lifting plate 5, giving the C-type lifting plate 5 enough lifting space, and then the C-type lifting plate 5 drives the rotating spur gear 11 and the driven spur gear 12 to move up and down, and can smoothly switch the transverse rotation or movement mode of the hanging plate 18. A tooth groove 22 is provided in the middle of the transverse rotating plate 21, and the circumferential surface of the rotating shaft 13 is provided with a driven spur gear 20 matching the tooth groove 22, and the driven spur gear 20 is arranged between the transverse rotating plate 21 and the bevel gear 14; It should be noted that the diameters and the number of teeth of the rotating spur gear 11, the driven spur gear 12, the driven spur gear 20 and the tooth groove 22 are the same. Therefore, after the rotating spur gear 11 drives the driven spur gear 12 to rotate horizontally to any angle, the driven spur gear 20 can be inserted into the tooth groove 22 after vertical movement, so that the driven spur gear 20 can be stably clamped and fixed with the horizontal rotating plate 21, and then can smoothly drive the horizontal rotating plate 21 to rotate when the driven spur gear 20 rotates.

[0022] The lower surfaces of the left and right sides of the transverse rotating plate 21 are provided with moving grooves 23, and the insides of the two moving grooves 23 are slidably installed with limit connection blocks 24. The lower ends of the two limit connection blocks 24 are respectively fixedly connected to the upper ends of the two moving blocks 17. The setting of the moving grooves 23 and the limit connection blocks 24 provides a movable space for the limit connection blocks 24, so that the limit connection blocks 24 can smoothly move horizontally, thereby driving the moving blocks 17 and the hanging plate 18 to smoothly move horizontally. A rotating shaft 3 28 is rotatably installed inside the lower end of the connecting column 2, and the lower end of the rotating shaft 3 28 passes through the upper end of the hanging platform 3, and a cross movable groove 29 is opened inside the lower end of the rotating shaft 3 28, and a cross connecting block 2 30 is inserted into the cross movable groove 29. The setting of the cross movable groove 29 provides a movable space for the cross connecting block 2 30, so that the cross connecting block 2 30 can smoothly move vertically, and the lower end of the cross connecting block 2 30 is fixedly connected to the upper end of the rotating shaft 2 13. The setting of the cross connecting block 2 30 enables the rotating shaft 2 13 to move vertically on the rotating shaft 3 28 without affecting the rotating shaft 2 13 driving the rotating shaft 3 28 to rotate, and through the setting of the rotating shaft 3 28, the cross connecting block 2 30 and the rotating shaft 2 13 can be limitedly installed, so that the rotating shaft 2 13 is always above the center of the hanging plate 18, and then stably drives the hanging plate 18 to rotate horizontally; It should be noted that the lengths of the cross movable groove 1 8 and the cross movable groove 2 29 are the same, and the length of one end of the cross connecting block 2 30 located inside the cross movable groove 29 is the same as the length of the cross connecting block 9, so that the cross connecting block 9 and the cross connecting block 2 30 move upward by the same distance, and then the hydraulic cylinder 4 drives the rotating spur gear 11 and the driven spur gear 1 12 to move upward by the same distance through the C-shaped lifting plate 5, further limiting the vertical movement distance of the rotating spur gear 11 and the driven spur gear 1 12, ensuring that the rotating spur gear 11 and the driven spur gear 1 12 are always in a meshing state, so that when the servo motor 6 is working, it can smoothly drive the driven spur gear 1 12 and the rotating shaft 2 13 to rotate by the rotating spur gear 11.

[0023] When the present invention is in use, when it is necessary to hoist the electric equipment, it is first connected to the electric equipment through the hook 19, and then the electric equipment is hoisted by the cantilever 1. After that, after it is moved to the installation position, the electric equipment is first suspended above the preset installation position by the cantilever 1, and then the hydraulic cylinder 4 is started. The hydraulic cylinder 4 drives the C-shaped lifting plate 5 to move upward, so that the C-shaped lifting plate 5 drives the rotating spur gear 11 and the driven spur gear 1 12 to move upward, and drives the bevel gear 1 14 to move upward and disengage from the meshing state of the bevel gear 2 15. At the same time, the driven spur gear 2 20 moves to the inside of the tooth groove 22 of the transverse rotating plate 21, and the driven spur gear 2 20 is clamped in the inside of the transverse rotating plate 21, so that the rotating shaft 2 13, the driven spur gear 2 20 and the transverse rotating plate 21 are formed. Into a whole, at this time, the servo motor 6 is started, the servo motor 6 drives the motor shaft 7 to rotate, the motor shaft 7 drives the rotating shaft 10 and the rotating spur gear 11 to rotate through the cross connection block 19, the rotating spur gear 11 drives the driven spur gear 12 and the rotating shaft 2 13 to rotate, because the bevel gear 14 is not engaged with the bevel gear 2 15, it will not drive the bevel gear 2 15 to rotate at this time, and the rotating shaft 10 drives the driven spur gear 2 20 to rotate, so that the driven spur gear 2 20 can drive the horizontal rotating plate 21 to rotate, and then the horizontal rotating plate 21 drives the hanging plate 18 to rotate horizontally through the limit connection block 24 and the moving block 17, so that the hanging plate 18 drives the power equipment to rotate horizontally by a certain angle through the hook 19, so that the orientation of the power equipment is the same as the installation position; Then the hydraulic cylinder 4 moves downward to reset the C-shaped lifting plate 5, so that the bevel gear 14 is meshed with the bevel gear 2 15, and at the same time the driven spur gear 2 20 moves out from the tooth groove 22 and moves to the bottom of the transverse rotating plate 21, and then the servo motor 6 is started again, the servo motor 6 drives the motor shaft 7 to rotate, the motor shaft 7 drives the rotating shaft 10 and the rotating spur gear 11 to rotate through the cross connecting block 19, and the rotating spur gear 11 drives the driven spur gear 12 and the rotating shaft 2 13 to rotate, at this time the driven spur gear 2 20 is no longer in contact with the transverse rotating plate 21 The rotating shaft 10 will only drive the driven spur gear 20 to rotate idly, and will no longer drive the horizontal rotating plate 21 to rotate. At the same time, the rotation of the bevel gear 14 will drive the bevel gear 2 15 and the threaded rod 16 to rotate, so that the moving block 17 can drive the hanging plate 18 to move in the horizontal direction, and then the power equipment can be accurately moved to the top of the installation position, completing the lateral angle adjustment and horizontal fine-tuning of the power equipment. Then the cantilever 1 slowly lowers the power equipment vertically through the hanging platform 3 to complete the installation of the power equipment.
