Description

Technical Field

[0002] Electrical maintenance and installation work often requires working at height, such as on transmission towers, substations, or power facilities in urban high-rise buildings. These high-altitude operations carry a significant risk of falling, so fall protection devices are essential to ensure the safety of workers.

[0003] Currently, when climbing transmission towers, power maintenance personnel use a safety rope to prevent falling. That is, a safety rope is fixed to the top of the tower, and the maintenance personnel connect their own anti-fall device to the safety rope. This anti-fall device is simple and easy to carry.

[0004] However, it is difficult to fix the safety rope to the upper part of the tower. In most cases, a lifting device is required to install the fixing device at the upper end of the safety rope to the tower. This fixing process is very troublesome, and the lifting device is not available in all areas. Therefore, special drones have now appeared. The drone drives the fixing device to the upper part of the tower, and the bottom of the fixing device is stuck on the angle steel of the tower.

[0005] Since drones cannot operate bolt tightening, the fixing device needs to have good self-locking ability to ensure that the fixing device will not be unlocked due to force. Utility Model Content

[0024] A hanging hole 4 is provided at the lower end of the vertical frame 1 , a hanging ring 5 is provided on the hanging hole 4 , and a safety rope 6 is tied to the hanging ring 5 .

[0025] The rotating frame is an integrated portal frame consisting of a cross bar 7, an outer vertical bar 91, and an inner vertical bar 92. The outer vertical bar 91 and the inner vertical bar 92 are respectively connected to the two ends of the cross bar 7. An axial hole is provided in the middle of the cross bar 7. The distance between the connecting shaft 8 and the inner vertical bar 92 is greater than the width of the tower. The connecting shaft 8 passes through the axial hole, and the rotating frame can rotate in a circle with the connecting shaft 8 as the center; the outer vertical bar 91 is longer than the inner vertical bar 92, and an end plate 15 is provided on the outer side of the lower end of the outer vertical bar 91, and a lock hole 16 is provided on the end plate 15. A positioning plate 24 with a positioning groove 25 is provided on the outer side of the inner vertical bar 92.

[0026] After the rotating frame rotates 90°, the outer vertical rod 91 is located in the hollow portion of the horizontal frame 2 , and the horizontal rod 7 is located in the hollow portion of the hook frame 3 .

[0027] The locking mechanism includes a first locking mechanism and a second locking mechanism. The first locking mechanism is composed of a top plate 10, a sleeve 11, a heavy shaft 12, and a plug 122. The top plate 10 is arranged on the upper side of the cross frame 2. A through hole 101 is provided in the middle of the top plate 10. The sleeve 11 is a hollow tube, which is fixed on the top plate 10. The sleeve 11 is concentric with the through hole 101. The heavy shaft 12 is slidably installed in the sleeve 11. A baffle 121 is provided at the lower end of the heavy shaft 12. The plug 122 is fixed at the center of the baffle 121. The diameter of the baffle 121 is smaller than the diameter of the through hole 101 and larger than the inner diameter of the sleeve 11. The plug 122 can pass through the through hole 101 and be inserted into the positioning groove 25 of the positioning plate 24.

[0028] A connecting plate 13 is provided at the upper end of the heavy shaft 12 , and the drone is lifted and detached from the device through the connecting plate 13 .

[0029] The second locking mechanism consists of a side plate 14, a pressure plate 18, and a short shaft 17. The side plate 14 is fixed to the hollow part in the middle of the vertical frame 1. After the rotating frame rotates 90 degrees, the end plate 15 is close to and opposite to the side plate 14. A transverse axis 20 is provided on the upper end of the side plate 14. A torsion spring 21 is provided on the transverse axis 20. The upper end of the pressure plate 18 is connected and fixed to the rotating shaft. One end of the torsion spring 21 is connected and fixed to the side plate 14, and the other end is connected and fixed to the pressure plate 18. A through hole 19 is opened in the center of the side plate 14, and the short shaft 17 is located in the through hole. 19, the rear end of the short shaft 17 is hinged to the middle part of the pressure plate 18. The rotation of the pressure plate 18 can drive the short shaft 17 to slide in the through hole 19. The short shaft 17 extends and can be inserted into the lock hole 16 on the end plate 15. A steel wire rope 23 is provided at the lower end of the pressure plate 18. The lower end of the steel wire rope 23 is connected to the upper section of the safety rope 6. The steel wire rope 23 is a rigid rope. When the safety rope 6 encounters a sudden falling force, a certain degree of tensile deformation will occur. This deformation is sufficient to drive the pressure plate 18 to change its angle through the steel wire rope 23.

[0030] The working principle of this device is:

[0031] Tie the safety rope 6 to the hanging ring 5, tie the upper end of the wire rope 23 to the ring 22 at the lower end of the pressure plate 18, and the wire rope 23 should be in a straightened state, and ensure that under the action of the torsion spring 21, the short shaft 17 will not pass through the through hole 19, and then use the connecting plate to hang the device on the lower side of the started drone, control the drone to lift the device to the upper part of the tower, and then select a suitable angle steel frame 26, control the drone to align the rotating frame with the angle steel frame 26, and gradually lower it. During the alignment process, the angle steel frame 26 should Close to the inner vertical rod 92, the rotating frame will rotate with the lower part of the hook hanger, and will eventually be stuck on the outer sides of the upper and lower ends of the angle steel frame 26. After the rotation is completed, the drone descends and exerts downward force on the counterweight shaft 12, pushing the plug 122 into the positioning groove 25. After completing the above steps, the drone is detached. When the ground personnel pull the safety rope 6 by hand, the wire rope 23 on the second locking mechanism will drive the pressure plate 18 to rotate. The rotation of the pressure plate 18 will drive the short shaft 17 to pass through the through hole 19 and insert into the lock hole 16, thereby locking the upper and lower ends.

[0032] It should be noted that when the safety rope 6 is not subjected to downward tension, under the action of the torsion spring 21, the short shaft 17 will not pass through the through hole 19, so that the drone can directly lift the device upwards and remove it.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
