Description

Specialized operating equipment for substations

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on September 5, 2023, with application number 202311140198.9 and invention name “Specialized operating equipment for substations”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of power auxiliary equipment, and in particular to a special operating equipment for a substation. Background Art

[0003] Currently, during the construction, renovation, operation, and maintenance of power systems, the timeliness and efficiency of replacing faulty equipment within the power system are key indicators for evaluating the overall management of the power grid. Domestic substations typically use traditional methods, such as cranes and maintenance personnel climbing to the heights, to replace porcelain-column equipment, such as 220kV lightning arresters, CVTs (capacitor voltage transformers), and post insulators.

[0004] To enable cranes to operate properly on porcelain column-type equipment at any angle, a horizontally rotatable boom is mounted on the crane's main body. Specifically, a motor and a rotating shaft are mounted on the main body, with the motor connected to the boom via the rotating shaft. However, due to the typically long boom and the heavy weight of the electrical equipment, such as porcelain columns, that the boom is often required to lift, the rotating shaft can easily bend and damage due to excessive bending torque. This can cause the crane's center of gravity to shift, leading to the crane tipping over and significantly threatening its safety and reliability.

[0005] Summary of the Invention

[0006] Based on this, it is necessary to provide a special operating equipment for substations to address the problem that the center of gravity deviation causes the risk of crane tipping over, affecting the safety and reliability of crane use.

[0007] In one aspect, the present application provides a dedicated operating device for a substation, comprising:

[0009] A steering drive module, comprising a drive motor, a driving gear, and a passive ring gear, wherein the drive motor is disposed on the mobile chassis, the driving gear is connected to the drive motor, and the driving gear is meshed with the passive ring gear;

[0010] a telescopic boom module, the telescopic boom module being rotatably disposed on the mobile chassis and connected to the passive ring gear; and

[0011] A plurality of telescopic legs are movably arranged at intervals on the peripheral edge of the mobile chassis, and the telescopic legs can be extended and support the ground in a working state.

[0012] The special operation equipment for substations of the above scheme can be specifically used in construction sites for installation, construction, maintenance, and component replacement of power equipment. When in use, the mobile chassis provides motor power so that the equipment can be moved to the work site, and then the driving motor drives the active gear, which drives the passive ring gear to rotate, so that the passive ring gear can further drive the telescopic boom module to rotate to any angle in the horizontal direction, thereby facilitating the operation of different power equipment in different positions of the equipment. Since the telescopic boom module is connected to the active gear through the passive ring gear, the gear pair has high meshing strength and strong load-bearing capacity, which can ensure sufficient structural rigidity and prevent the telescopic boom module from deforming and bending due to excessive load. At the same time, multiple telescopic legs move relative to the mobile chassis to extend and support the ground, providing lateral support for the mobile chassis, further ensuring the stability of the posture of the special operation equipment for substations, preventing the problem of tipping due to the deviation of the center of gravity of the equipment, and improving the safety and reliability of the equipment.

[0037] 1 , which shows a dedicated operating device for a substation according to an embodiment of the present application, including a mobile chassis 10 , a steering drive module 20 , a telescopic boom module 30 , and a plurality of telescopic legs 40 .

[0038] The mobile chassis 10 is the main structure of the entire specialized operating equipment, used to carry and support the steering drive module 20, the telescopic boom module 30, and the multiple telescopic legs 40. For example, the mobile chassis 10 can be any of a wheeled chassis and a tracked chassis. Specifically, in this embodiment, the mobile chassis 10 is a tracked chassis, and the ends of the tracked chassis are provided with an upwardly inclined slope structure to create a clearance between the chassis and the ground, thereby improving the tracked chassis's ability to pass through obstacles on the ground.

[0039] Please continue to refer to Figures 1 to 3. The steering drive module 20 includes a drive motor, a driving gear 21 and a passive ring gear 22. The drive motor is arranged on the mobile chassis 10, the driving gear 21 is connected to the drive motor, and the driving gear 21 is engaged with the passive ring gear 22; the telescopic boom module 30 is rotatably arranged on the mobile chassis 10 and connected to the passive ring gear 22; a plurality of telescopic legs 40 are movably arranged at intervals at the outer peripheral edge of the mobile chassis 10, and the telescopic legs 40 can be extended and support the ground in the working state.

[0040] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: the special operating equipment for substations of the above solution can be used in construction scenarios such as installation, maintenance, and component replacement of power equipment. During use, the mobile chassis 10 provides maneuvering force so that the equipment can be moved to the work site, and then the driving motor drives the active gear 21, and the active gear 21 drives the passive ring gear 22 to rotate, so that the passive ring gear 22 can further drive the telescopic boom module 30 to rotate in the horizontal direction to any angle, thereby facilitating the operation of different power equipment in different positions of the equipment. Since the telescopic boom module 30 is connected to the active gear 21 through the passive ring gear 22, the gear pair has high meshing strength and strong load-bearing capacity, which can ensure sufficient structural rigidity to prevent the telescopic boom module 30 from deforming and bending due to excessive load. At the same time, multiple telescopic legs 40 move relative to the mobile chassis 10 and extend and support the ground, which has a lateral support effect on the mobile chassis 10, further ensuring the stability of the posture of the special operating equipment used in the substation, preventing the problem of tipping due to the deviation of the center of gravity of the equipment, and improving the safety and reliability of the equipment.

[0041] Continuing with Figure 2 , the steering drive module 20 further comprises, based on the above-described embodiment, a plurality of reinforcing ribs 23 arranged at intervals along the circumference of the connection between the telescopic boom module 30 and the passive ring gear 22. The reinforcing ribs 23 increase the strength and rigidity of the connection between the passive ring gear 22 and the telescopic boom module 30, thereby improving the overall structural performance and stability and preventing cracks or even breakage at the connection between the telescopic boom module 30 and the passive ring gear 22 due to excessive stress concentration.

[0042] In some embodiments, the telescopic boom module 30 includes a boom seat 31, a telescopic arm 32 and a mechanical claw 33. The boom seat 31 is connected to the passive ring gear 22, one end of the telescopic arm 32 is fixed on the boom seat 31, and the other end of the telescopic arm 32 is connected to the mechanical claw 33.

[0043] The boom mount 31 is used to support the telescopic boom 32 and the mechanical claw 33 and can rotate synchronously with the passive ring gear 22 to change the working position and location of the telescopic boom module 30. The telescopic boom 32 has the ability to extend and retract to drive the mechanical claw 33 close to the power equipment to perform related operations.

[0044] In this application, the mechanical claw 33 can optionally adopt a six-finger gripper, each finger of which can move independently or synchronously, so that the mechanical claw 33 can form different hand shapes, so as to more flexibly grasp electrical components with different shapes (such as porcelain bottles), thereby improving the applicability of the mechanical claw 33.

[0045] Furthermore, the telescopic boom module 30 includes a lifting cylinder 34. The base of the lifting cylinder 34 is rotatably mounted on the boom base 31, and the piston rod of the lifting cylinder 34 is rotatably connected to the telescopic arm 32. The lifting cylinder 34 is driven to extend and retract, thereby flexibly adjusting the tilt angle of the telescopic arm 32, so that the mechanical claw 33 can be positioned at different heights, facilitating operation on electrical equipment at different heights.

[0046] Furthermore, the telescopic boom module 30 also includes a stop collar 35. The telescopic boom 32 comprises at least two boom sections, which are nested and capable of relative telescopic movement. The stop collar 35 is connected between two adjacent boom sections. When the two adjacent boom sections are extended to their maximum length, the stop collar 35 abuts against the end of the nested boom section, creating a stop effect and preventing the adjacent boom sections from excessive movement or falling off.

[0047] Please continue to refer to Figure 2. In addition, in some other embodiments, the telescopic boom module 30 also includes a rope winder 36, a rope 37, a guide plate 38 and a roller 39. The rope winder 36 is installed at one end of the telescopic arm 32 close to the boom seat 31, the guide plate 38 is arranged on the telescopic arm 32, and the roller 39 is rotatably installed at the end of the telescopic arm 32 away from the boom seat 31. One end of the rope 37 is connected to the rope winder 36, and the other end of the rope 37 passes through the guide hole of the guide plate 38 and is wrapped around the outside of the roller 39 and connected to the mechanical claw 33.

[0048] During operation, the rope reel 36 can reel in the rope 37 to shorten it, allowing the rope 37 to lift the mechanical claw 33 upward, or reel out the rope 37 to lengthen it, allowing the rope 37 to lower the mechanical claw 33 downward, facilitating the mechanical claw 33's access to electrical components such as a porcelain bottle. During this process, the guide plate 38 guides and limits the rope 37's movement, ensuring smooth movement and preventing it from oscillating and vibrating, which could affect the mechanical claw 33's positional stability and, in turn, the mechanical claw's accuracy in accessing and placing electrical components such as a porcelain bottle.

[0049] In order to further suppress the impact of vibration on the working accuracy of the mechanical claw 33 and the service life of the telescopic boom module 30, on the basis of the above embodiment, the telescopic boom module 30 also includes a vibration suppression piezoelectric element, which is installed on the telescopic arm 32.

[0050] For example, when the vibration suppression piezoelectric element detects that the telescopic arm 32 is vibrating, the vibration suppression piezoelectric element will immediately generate a vibration force with the same amplitude and opposite direction to the detected vibration, thereby achieving mutual cancellation of the two-way vibration to restore the telescopic arm 32 to a stable posture.

[0051] Please continue to refer to Figures 3 to 4. In addition, based on any of the above embodiments, the telescopic leg 40 includes a rotating cylinder 41, a rotating seat 42, a swinging cylinder 43 and a leg unit 44. The rotating cylinder 41 is arranged on the mobile chassis 10, and the rotating seat 42 is connected to the rotating cylinder 41. One end of the leg unit 44 is rotatably mounted on the rotating seat 42, and the other end is used to support the ground. The base body of the swinging cylinder 43 is rotatably mounted on the rotating seat 42, and the piston rod of the swinging cylinder 43 is rotatably connected to the leg unit 44. The leg unit 44 has a built-in hydraulic cylinder and has telescopic capability.

[0052] The rotating cylinder 41 provides the driving force for the overall horizontal rotation of the telescopic leg 40, so that the telescopic leg 40 can be folded onto the mobile chassis 10 as a whole when not in operation, reducing the volume and occupied space, making it easier for the equipment to move in the narrow space within the substation, or the swing cylinder 43 and the leg unit 44 can be rotated to the outside of the side of the mobile chassis 10 when in operation, and then the swing cylinder 43 drives the piston rod to extend, driving the leg unit 44 to swing downward, and finally the leg unit 44 extends its side length by itself and supports the ground, thereby realizing the lateral support of the telescopic leg 40 for the mobile chassis 10, improving the stability of the equipment and preventing the equipment from tipping over.

[0053] Based on any of the above embodiments, the special operating equipment for the substation also includes a porcelain bottle holder 50, which is arranged on the mobile chassis 10. The porcelain bottle holder 50 is divided into multiple storage grooves 52 by horizontal and vertical partitions 51, and the storage grooves 52 are used to store porcelain bottles.

[0054] Continuing with FIG1 , the specialized operating equipment for a substation further includes an obstacle board 60, which is detachably mounted on the mobile chassis 10. During use, the obstacle board 60 can be released and dropped to the ground, covering ground obstacles (such as ground cables), allowing the mobile chassis 10 to pass over the obstacle board 60 without directly crushing the ground obstacles, thereby improving the equipment's obstacle-crossing capability.

[0055] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
