Description

Technical Field

[0001] The utility model relates to the technical field of operation and maintenance, and more specifically to an operation and maintenance device for a power transmission line. Background Art

[0002] Transmission line operation and maintenance equipment is constantly being improved under the demand of ensuring grid stability and user power safety, combined with the shortcomings of traditional maintenance methods and the development of modern technology. The development of these devices and technologies is of great significance to improving the operation and maintenance level of the power system and ensuring the stability of power supply.

[0003] The Chinese patent authorization announcement number: CN218549314U provides a transmission line operation and inspection device. The scheme starts a first motor, and the output end of the first motor drives the threaded rod to rotate. When the threaded rod rotates, it drives the external threaded sleeve to move up and down under the action of a slider. When the threaded sleeve moves, it drives the cross bars on both sides to move up and down, and drives the fixed plate at the upper end of the cross bar to push the bearing plate to move up and down, thereby realizing the maintenance of transmission lines at different heights and improving usability.

[0004] However, when using traditional transmission line operation and maintenance equipment, when the workers lift the hanging basket through a crane, the hanging basket will remain in its original static state due to inertia. When the crane starts to apply force to change its state, the existence of inertia will cause the hanging basket to shake at the moment of starting, increasing the risk of workers falling due to the shaking and reducing the safety factor of the working environment.

[0027] Example:

[0028] See also Figure 1-2 A transmission line operation and maintenance device comprises a hanging basket 1, a mechanical arm 4 is fixedly connected to the outer end of the hanging basket 1, a pair of slide rails 3 are provided on the inner wall of the hanging basket 1, a door body 5 is rotatably connected to the outer end of the slide rail 3, and a limit assembly 2 is provided inside the slide rail 3;

[0029] The limiting assembly 2 includes a roller 28 slidably connected to the slide rail 3 , a connecting plate 29 is fixedly connected to the top of the roller 28 , and a moving plate 21 is fixedly connected to one end of the connecting plate 29 away from the roller 28 .

[0030] The transmission line operation and maintenance device in this scheme is an important tool and equipment to ensure the normal operation, safety and stability of the transmission line, specifically a transmission line operation and maintenance hanging basket, which can improve the operation efficiency of the line, reduce the failure rate, reduce the power outage time, and provide strong support for the stable operation of the power system. When the transmission line needs to be operated and maintained, the door body 5 should be opened first, and then the staff should move between a pair of movable plates 21.

[0031] In addition, a special connecting plate is used to connect the mechanical arm 4 and the crane outside the device, so that the staff can transport the hanging basket 1 to a suitable height through the external crane, and when the limit plate 24 is parallel to the movable plate 21, the limit plate 24 and the midpoint of the output end of the electric telescopic rod 23 are in the same horizontal plane.

[0032] See also Figure 2 A reserved groove 22 communicating with the outside world is provided at the top of the movable plate 21, and an electric telescopic rod 23 is fixedly connected to the inner wall of the reserved groove 22. A pair of rotating rods 25 are rotatably connected to the top of the movable plate 21. A slide groove 26 communicating with the outside world is provided at the outer end of the rotating rod 25. A limit plate 24 is slidably connected to the inner wall of the slide groove 26. The limit plate 24 is adapted to the electric telescopic rod 23. A limit groove 27 is provided at the top of the limit plate 24. The limit groove 27 penetrates the limit plate 24 and is connected to the outside world.

[0033] The outer end of the limit groove 27 of the present invention is wrapped with foam material to play a buffering role. When the staff moves between the pair of movable plates 21, the staff can then rotate the slide groove 26 to make the limit plate 24 and the midpoint of the output end of the electric telescopic rod 23 be at the same horizontal plane. Then the staff starts the electric telescopic rod 23, so that the output end of the electric telescopic rod 23 extends until it abuts against the outer end of the limit plate 24, and continues to control the extension of the output end of the electric telescopic rod 23. The pair of limit plates 24 will move closer to each other along the inner wall of the slide groove 26 until the limit groove 27 completes the limitation of the staff. At this time, the crane is started. Since the position of the staff is restricted, when the crane starts to apply force to change the state of the hanging basket 1, the risk of the staff falling due to the existence of inertia is prevented, thereby ensuring the safety and stability of the working environment. Then the crane transports the hanging basket 1 to a suitable height, and the staff can cooperate with the waist and legs to make the roller 28 slide in the slide rail 3 to meet the purpose of the staff to operate and maintain the power transmission lines at different positions.

[0034] See also Figure 3 The outer end of the hanging basket 1 is fixedly connected with a fixing block 8, a screw 7 is provided at the top of the fixing block 8, a threaded hole connected to the outside is opened at the top of the fixing block 8, the screw 7 is threadedly connected to the threaded hole, and a reserved hole 6 is opened at the top of the door body 5, the reserved hole 6 is adapted to the screw 7, and the reserved hole 6 is located below the fixing block 8.

[0035] In this solution, when the staff completes the operation and maintenance of the transmission line, the crane is controlled to transport the staff to the ground. Then the staff can turn the screw 7 to make the door body 5 break away from the position restriction of the screw 7. Then the staff gives a thrust to the door body 5 to open it, and can walk out of the interior of the hanging basket 1.

[0036] Working principle: when the staff is needed to operate and maintain the transmission line, the door body 5 should be opened first, and then the staff should move between the pair of movable plates 21. Then the staff can make the limit plate 24 and the midpoint of the output end of the electric telescopic rod 23 be at the same horizontal plane by rotating the slide slot 26. Then the staff starts the electric telescopic rod 23, so that the output end of the electric telescopic rod 23 extends until it abuts against the outer end of the limit plate 24, and continues to control the extension of the output end of the electric telescopic rod 23. The pair of limit plates 24 will move closer to each other along the inner wall of the slide slot 26 until the limit slot 27 completes the limit of the staff. At this time, the crane is started. Since the position of the staff is restricted, when the crane begins to apply force to change the state of the hanging basket 1, the risk of the staff falling due to the existence of inertia is prevented, ensuring the safety and stability of the working environment. Then the crane transports the hanging basket 1 to a suitable height, and the staff can cooperate with the waist and legs to make the roller 28 slide in the slide rail 3 to meet the purpose of the staff to operate and maintain the transmission lines at different positions.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
