Description

Technical Field

[0001] The utility model relates to the field of safety protection, and in particular to a convenient anti-fall locking device. Background Art

[0002] In the power industry, working at height is a common type of work. These operations are often accompanied by the risk of falling, so fall protection devices are important equipment to ensure the safety of workers.

[0003] The current high-altitude safety rope is fixed to the top of the tower through lifting equipment. This method is not only inefficient, but also in some areas where lifting equipment cannot enter, climbing can only rely on simple personal fall protection equipment, which is very dangerous.

[0004] With the development of drone technology, there are now special lifting drones that pull the upper end of the high-altitude safety rope to the top of the tower and then fix it on the tower. This method is convenient and efficient and can adapt to towers in most areas.

[0005] However, the current fastener has a simple structure and only adopts a simple hook structure, which is very easy to fall off. Utility Model Content

[0006] The present invention is based on the above technical problems and proposes a convenient anti-fall locking device.

[0007] The locking mechanism is configured to lock the locking mechanism, wherein the locking mechanism has a lock on the top of the locking mechanism, and the lock is configured to lock the locking mechanism. The locking mechanism comprises a through-hole, a hole, and a nut. The through-hole is formed on the bottom of the locking mechanism, and the two locking mechanisms are connected separately.

[0008] Preferably, an inverted L-shaped limit plate is provided in the fixer, the front end of the limit plate is connected to the upper part of the vertical rod, the lower end of the limit plate is connected to the front part of the lower rod, the limit plate and the fixer are an integrated structure, the limit plate and the area surrounded by the vertical rod and the lower rod form a closed space, a battery and a controller are provided in the closed space, the battery supplies power to the controller and the electric push rod, and the controller is electrically connected to the electric push rod.

[0009] Preferably, a gap is left between the limit plate and the upper rod, and in the horizontal direction, a gap is also left between the slide plate and the limit plate, and the tower rod is inserted into the gap between the limit plate and the upper rod and between the slide plate and the limit plate.

[0010] Preferably, a groove is provided on the front side wall of the lower through hole, and the groove is opposite to the lower through hole and has the same size as the lower through hole.

[0011] Preferably, a pressure-sensitive button is provided on the upper inner side of the vertical rod, and the pressure-sensitive button is electrically connected to the controller.

[0012] Beneficial effect: This device adopts an automatic locking structure. When the drone clamps the holder on the tower, the slide falls to close the front of the holder. The slide and the holder form a closed loop structure, which is equivalent to a closed hook and will not fall off the tower. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0017] Example 1

[0018] In this embodiment, if Figures 1 to 3 The convenient anti-fall locking device shown includes: a fixer 1, a docking rod 2 is provided at the upper end of the fixer 1, and the docking rod 2 is connected to the docking device at the bottom of the drone. On the ground, the upper end of the docking rod 2 is installed on the docking device, and the docking device can lock the docking rod 2, and can also unlock the docking rod 2 and detach from the docking rod 2; a connector 3 is provided at the lower part of the fixer 1, and a safety rope can be fastened to the connector 3. This connection structure is an existing mature technology and will not be described in detail here.

[0019] The fixer 1 is composed of an integrated upper rod 4, a vertical rod 5 and a lower rod 6. The two ends of the vertical rod 5 are respectively connected to the rear ends of the upper rod 4 and the lower rod 6. The upper rod 4 and the lower rod 6 are parallel and perpendicular to the vertical rod 5; the front parts of the upper rod 4 and the lower rod 6 are respectively provided with an upper through hole 7 and a lower through hole 8 facing each other, a slide 9 is provided in the upper through hole 7, a top plate 10 is provided on the upper end of the slide 9, the slide 9 is parallel to the vertical rod 5, and a slide groove 11 is provided on the rear side wall of the upper through hole 7 and the lower through hole 8. A locking plate 12 is provided in the slide groove 11, a card slot 14 is provided on the upper part of the slide 9, and a card hole 15 is provided at the lower part of the slide 9. The initial position of the slide 9 is above the upper through hole 7, and the card hole 15 at the lower end of the slide 9 is located above the upper through hole 7. The upper locking plate 12 is inserted into the hole 7 and locked by inserting the upper locking plate 12 into the card hole 15. When the fixer 1 is stuck on the tower rod 22, the electric push rod 13 drives the upper locking plate 12 to retract, and the slide plate 9 moves downward under the action of gravity until it is blocked by the top plate 10. At this time, the lower end of the slide plate 9 is inserted into the lower through hole 8, and the card hole 15 is aligned with the lower locking plate 12. The lower electric push rod 13 is started to drive the lock plate 12 to be inserted into the card hole 15. If it is continued to be inserted, the front end of the lock plate 12 can be stuck in the groove 16 on the front side wall of the lower through hole 8, and then the upper electric push rod 13 is started again to insert the upper lock plate 12 into the card slot 14 to complete the upper and lower locking of the slide plate 9.

[0020] An inverted L-shaped limit plate 17 is provided in the fixer 1, the front end of the limit plate 17 is connected to the upper part of the vertical rod 5, and the lower end of the limit plate 17 is connected to the front part of the lower rod 6. The limit plate 17 and the fixer 1 are an integrated structure. The area enclosed by the limit plate 17, the vertical rod 5 and the lower rod 6 forms a closed space 18. A battery 19 and a controller 20 are provided in the closed space 18. The battery 19 supplies power to the controller 20 and the electric push rod 13, and the controller 20 is electrically connected to the electric push rod 13.

[0021] In one possible implementation, the tower pole 22 is usually an angle steel. In order to reduce the shaking of the fixer 1 on the tower pole 22, a gap is left between the limit plate 17 and the upper rod 4. In the horizontal direction, a gap is also left between the slide plate 9 and the limit plate 17. The tower pole 22 is inserted into the gap between the limit plate 17 and the upper rod 4 and between the slide plate 9 and the limit plate 17. The slide plate 9 can close the rear side of the tower pole 22, and the L-shaped tower pole 22 is confined in the L-shaped gap.

[0022] In addition, it should be noted that in actual application, the tower rod 22 may block the slide plate 9 from sliding down. This is because the tower rod 22 has not completely entered the fixer 1, so a push rod will be set on the front side of the drone. When the docking rod 2 is detached from the drone, the ground personnel can operate the drone to use the push rod to push the vertical plate so that the tower rod 22 fits tightly with the fixer 1.

[0023] In order to facilitate identification of whether the holder 1 is installed on the tower pole 22 , a pressure-sensitive button 21 is provided on the upper inner side of the vertical pole 5 , and the pressure-sensitive button 21 is electrically connected to the controller 20 .

[0024] 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.
