Description

Technical Field

[0002] A power line-laying drone is an industrial-grade drone specially used for power line installation. There are often special environmental restrictions such as rivers, cliffs, and forests between the towers where high-voltage power lines are erected. Manual line laying is time-consuming and inefficient, while drones have the ability to operate over large spans and large drop heights. Drones can tow a guide rope from the air and fly across multiple towers at a time, adapting to a variety of environmental requirements and greatly improving work efficiency. Power line-laying drones usually mount guide ropes on their fuselages and use their own flying capabilities to apply tension to the guide ropes in the air, thereby releasing the wires in the air. The guide ropes span multiple towers, and are temporarily fixed on the towers by construction workers on the towers. Later, construction workers fix the guide ropes and use them to tow subsequent ropes or cables to complete the entire process of cross-line laying.

The frame includes an upper base plate and a lower base plate fixedly connected to the upper base plate. A driving rod is fixedly arranged on the mounting plate, and the driving rod is splined to a guide cylinder. An electromagnetic block 1 is arranged on the top of the guide cylinder, and an electromagnetic block 2 adapted to the electromagnetic block 1 is arranged in the driving rod. The driving rod has a spiral guide rib 1 and a guide rib 2. A spiral groove 1 adapted to the guide rib 1 is arranged in the first sliding sleeve, and a spiral groove 2 adapted to the guide rib 2 is arranged in the second sliding sleeve. The spiral lead angles of the spiral groove 1 and the spiral groove 2 are the same, and the spiral directions of the spiral groove 1 and the spiral groove 2 are opposite; a reset spring 1 is arranged between the guide cylinder and the driving rod, and a reset spring 2 is arranged between the driving rod and the lower base plate.

The two first worm wheels (22) rotate to turn the lead rope into a C shape, and at the same time, the two ends of the lead rope are clamped in the second bracket (27), and the equipment is ready; Step 2: Control the drone body (1) to fly to a preset position above the iron tower, the output end of the second servo motor (31) of the loop connection device (3) rotates to drive the second worm (33) to rotate, the second worm (33) rotates to drive the two second worm wheels (32), the second worm wheels (32) rotate to drive the rotating semicircle (34), the rotating semicircle (34) surrounds one of the steel frames on the upper side of the iron tower, and the guide rope is located on the upper side of the steel frame and inside the inner circle of the rotating semicircle (34); Step 3: The output end of the third servo motor (42) rotates to drive the conveying wheel (43) to rotate. The conveying wheel (43) rotates to convey the iron wire into the two rotating semicircles (34). The iron wire is restricted by the rotating semicircles (34) and the rubber sheet (36) to form a ring. The output end of the reduction motor (53) rotates to drive the rotating column (54) to rotate. The rotating column (54) and the guide frame (44) cooperate to cut the iron wire. The rotating electric claw (51) starts to drive the extension rod (52) to start. The extension rod (52) clamps the ring formed by the iron wire and rotates. The diameter of the ring formed by the iron wire decreases after rotation. The ring formed by the iron wire passes through the rubber sheet (36) of part of the rotating semicircle (34). The rotating semicircle (34) is opened. The ring formed by the iron wire passes through the rubber sheet (36) of most of the rotating semicircle (34). The drone body (1) moves upward to withdraw the iron wire from the extension rod (52). At this time, the guide rope is restricted on the iron tower by the iron wire ring.
