Description

Technical Field

[0001] This invention relates to the field of power transmission maintenance visualization technology, and specifically to a power transmission maintenance visualization auxiliary device. Background Technology

[0002] Safety monitoring of power transmission lines relies on visualization equipment installed on the towers. In existing technologies, equipment maintenance requires technicians to climb to heights, posing significant risks such as falls and electric shocks. To address the challenge of dismantling parts at heights, Chinese patent CN113746025B discloses a maintenance auxiliary device for a power transmission visualization server. This device uses a hoisting mechanism mounted on angle steel, with a toolbox at the bottom, and sliding grippers fixed to the angle steel at the top of the tower for easy storage of dismantled parts. While this device prevents parts from falling, it still requires technicians to climb to the top of the tower, failing to eliminate the inherent risks of working at heights. Statistics show that 70% of power transmission maintenance accidents occur during climbing and high-altitude operations, especially in adverse weather or complex terrain, where safety hazards are particularly prominent. Therefore, there is an urgent need for a remotely controllable, climb-free auxiliary device to enable ground-based operations, fundamentally ensuring the safety of technicians and improving maintenance efficiency. Summary of the Invention

[0003] This invention provides a power transmission maintenance visualization auxiliary device to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a power transmission maintenance visualization auxiliary device, comprising a horizontally arranged mounting plate, a connecting frame fixedly connected to the top surface of the mounting plate, a control module mounted on the mounting plate, a wireless signal transceiver module on the control module, a dual-output shaft motor mounted in the middle of the bottom surface of the mounting plate, and a drum connected to both ends of the dual-output shaft motor, the drum being rotatably connected to the mounting plate, a support plate below the mounting plate, pulley blocks mounted at both ends of the top surface of the support plate, the drum being connected to the pulley blocks by a steel wire rope; positioning posts fixedly connected to both ends of the top surface of the support plate, the positioning posts having slots, a fixing plate between the mounting plate and the support plate, the fixing plate extending to both ends of the mounting plate and connected to the mounting plate, positioning holes corresponding to the positioning posts being opened at both ends of the fixing plate, a first guide groove corresponding to the slot being opened on the inner side wall of the positioning hole, and a retractable clamping head slidably connected in the first guide groove.

[0005] Preferably, the side of the card head near the card slot is an inclined surface, with the higher side of the inclined surface positioned near the card slot. A second guide groove is provided inside the card head. The end of the second guide groove near the first guide groove is open and fixedly connected to a limit ring. A slider is slidably connected inside the second guide groove. A first electric telescopic rod is fixedly connected between the slider and the end of the first guide groove away from the card head. A spring is sleeved on the first electric telescopic rod.

[0006] Preferably, a second electric telescopic rod is fixedly connected between both ends of the mounting plate and both ends of the fixing plate.

[0007] Preferably, the top of the positioning post is provided with a tapered guide.

[0008] Preferably, the connecting frame includes two connecting rods fixedly connected to both ends of the mounting plate, and a connecting plate is fixedly connected to the top surface of the connecting rods, with a fixing through hole provided on the connecting plate.

[0009] The beneficial effects of this invention are as follows: (1) This invention uses a wireless control motor to drive the drum to release or rewind the wire rope, thereby raising and lowering the support plate carrying the visualization equipment, so that the visualization equipment can be disassembled and maintained on the ground. In this way, technicians can complete the maintenance of the visualization equipment without climbing the tower, reducing safety risks and improving maintenance efficiency and safety; (2) When the positioning column is inserted into the positioning hole, the top of the positioning column contacts the inclined surface of the clamp head, overcoming the spring force to push the clamp head back. When the clamp slot is aligned with the first guide slot, the spring automatically pushes the clamp head into the clamp slot and locks it. The process is smooth and reliable; (3) By setting a second electric telescopic rod and cooperating with the dual-output shaft motor to synchronously adjust the length of the wire rope, the raising and lowering of the visualization equipment can be remotely controlled, so that technicians can flexibly adjust the installation height of the equipment on the ground, thereby optimizing the monitoring angle to adapt to different monitoring needs.

[0012] The present invention will now be further described with reference to the accompanying drawings.

[0013] like Figure 1-4As shown, this invention provides a power transmission maintenance visualization auxiliary device, including a horizontally arranged mounting plate 1. A connecting frame 3 is fixedly connected to the top surface of the mounting plate 1. A control module 14 is mounted on the mounting plate 1, and the control module 14 is equipped with a wireless signal transceiver module. A dual-output shaft motor 2 is mounted in the middle of the bottom surface of the mounting plate 1. The dual-output shaft motor 2 is electrically connected to the control module 14. Both ends of the dual-output shaft motor 2 are driven by drums 4, which are rotatably connected to the mounting plate 1. A support plate 5 is provided below the mounting plate 1, and the visualization device is detachably connected to the support plate 5. Puller blocks 6 are installed at both ends of the top surface of the carrier plate 5, and the drum 4 is connected to the pulley blocks 6 by a steel wire rope 7. Positioning posts 8 are fixedly connected to both ends of the top surface of the carrier plate 5. The positioning posts 8 are provided with slots 9. A fixing plate 10 is provided between the mounting plate 1 and the carrier plate 5. The two ends of the fixing plate 10 extend to the two ends of the mounting plate 1 and are connected to the mounting plate 1. The two ends of the fixing plate 10 are provided with positioning holes 11 corresponding to the positioning posts 8. The inner sidewall of the positioning hole 11 is provided with a first guide groove 12 corresponding to the slot 9. A retractable clamping head 13 is slidably connected in the first guide groove 12.

[0014] Specifically, during the installation of the auxiliary device, technicians need to perform a high-altitude operation, using the connecting frame 3 to fix the auxiliary device to the angle steel 23 at the top of the tower. When disassembling and maintaining the visualization equipment, technicians send commands from the ground via a wireless terminal to control the retraction of the clamp head 13 from the clamp slot 9. Simultaneously, the dual-shaft motor 2 reverses to release the steel wire rope 7, causing the support plate 5 and the visualization equipment to descend to the ground at a uniform speed. Technicians can then disassemble the visualization equipment for maintenance. After maintenance, the visualization equipment is reinstalled on the support plate 5. The dual-shaft motor 2 is then controlled to rotate forward to tighten the steel wire rope 7, causing the support plate 5 to rise. When the support plate 5 reaches its highest point, the clamp slot 9 aligns with the first guide groove 12, and the clamp head 13 extends and embeds into the clamp slot 9, thereby locking and securing the support plate 5 and the visualization equipment. This invention, by setting up a dual-shaft motor 2 and a drum 4 to drive the visualization equipment up and down, allows technicians to disassemble and maintain the visualization equipment from the ground, eliminating the need for workers to perform high-altitude maintenance, fundamentally ensuring the safety of technicians and improving maintenance efficiency.

[0015] In some embodiments, the side of the card head 13 near the card slot 9 is inclined, and the higher side of the inclined surface is located near the card slot 9. A second guide groove 15 is provided in the card head 13. The end of the second guide groove 15 near the first guide groove 12 is open and fixedly connected to a limit ring 16. A slider 17 is slidably connected in the second guide groove 15. A first electric telescopic rod 18 is fixedly connected between the slider 17 and the end of the first guide groove 12 away from the card head 13. The first electric telescopic rod 18 is electrically connected to the control module 14. A spring 19 is sleeved on the first electric telescopic rod 18. Specifically, when the support plate 5 rises and drives the positioning post 8 to insert into the positioning hole 11, the top of the positioning post 8 rises and contacts the inclined surface of the clamp head 13. Subsequently, the positioning post 8 overcomes the elastic force of the spring 19 and pushes the clamp head 13 back into the guide groove. When the clamp groove 9 aligns with the first guide groove 12, the spring 19 releases its elastic force and pushes the clamp head 13 into the clamp groove 9, thereby completing the locking and fixing. When the support plate 5 descends and releases, the ground technician sends a command through the wireless terminal, and the control module 14 controls the first electric telescopic rod 18 to retract. The first electric telescopic rod 18 pulls the clamp head 13 back through the slider 17 and the limit ring 16, so that the clamp head 13 disengages from the clamp groove 9, thereby releasing the positioning post 8. By setting the clamp head 13, the spring 19, and the first electric telescopic rod 18, the automatic locking when the positioning post 8 is inserted and the remote control release of the positioning post 8 are achieved, thereby ensuring the stability and reliability of the lifting process of the visualization equipment.

[0016] In some embodiments, a second electric telescopic rod 20 is fixedly connected between both ends of the mounting plate 1 and both ends of the fixing plate 10. The second electric telescopic rod 20 is electrically connected to the control module 14. Specifically, in use, the second electric telescopic rod 20 is remotely started, which drives the fixing plate 10 and the support plate 5 to rise and fall. The dual-axis motor 2 rotates accordingly to adjust the length of the wire rope 7, thereby enabling stepless adjustment of the installation height of the visualization equipment. This allows for viewpoint optimization without lowering the visualization equipment to adapt to different monitoring viewpoint requirements.

[0017] In some embodiments, the top end of the positioning post 8 is provided with a tapered guide portion 21, which facilitates the insertion of the positioning post 8 into the positioning hole 11.

[0018] In some embodiments, the connecting frame 3 includes two connecting rods 31 fixedly connected to both ends of the mounting plate 1. A connecting plate 32 is fixedly connected to the top surface of the connecting rods 31. A fixing through hole 33 is provided on the connecting plate 32 so that the auxiliary device can be fixed to the angle steel 23 on the top of the tower by bolts 22.

[0019] In the above embodiments, the dual-output shaft motor 2 can be replaced with two synchronous servo motors to achieve more precise single-sided control. The connection method between the control module 14 and the dual-output shaft motor 2, the first electric telescopic rod 18, and the second electric telescopic rod 20 is existing technology and will not be described in detail here.

[0020] The above embodiments can be combined with each other.

[0021] The above embodiments are not intended to limit the shape, material, structure, etc. of the present invention in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
