[0033] Embodiment 1

[0034] Referring to Figure 1-Figure 4 , which is the first embodiment of the present invention. This embodiment provides a self-locking fixing device, including a limiting component 100, which includes a limiting frame 101 and a switch component 102 connected to the limiting frame 101. The switch component 102 is used to control the opening and closing of the entrance 101b of the limiting frame 101, facilitating the sleeving of the tower member into the limiting frame 101 and completing the bottom limiting of the tower member. A power component 103 is connected to the switch component 102, and the power component 103 is connected to a drone. After the drone takes off, the switch component 102 can be pulled by the power component 103. A fixed pulley 104 is arranged on the limiting frame 101, and a safety rope passes through the fixed pulley 104;

[0035] A safety component, including a receiving frame 201 connected to the limiting frame 101. The receiving frame 201 has a "C" - shaped structure. When installing, the tower member is sleeved into the receiving frame 201. A sliding block is arranged on one side of the receiving frame 201, and a sliding groove is arranged on one side of the limiting frame 101. The receiving frame 201 and the limiting frame 101 are slidably matched through the sliding block and the sliding groove. A lifting component 202 is arranged on the limiting frame 101, and the lifting component 202 can move the receiving frame 201 up and down. When the receiving frame 201 moves up to the top of the movable cavity 101c of the limiting frame 101, the limiting frame 101 and the receiving frame 201 cooperate to form a closed space, thereby completing the limiting of the tower member;

[0036] A fitting component 300, including a flipping component 301 arranged on the receiving frame 201. When the tower member is sleeved into the receiving frame 201, the tower member abuts against the flipping component 301, causing the flipping component 301 to rotate. A fitting component 302 is arranged on the receiving frame 201, and the fitting component 302 pushes the rotated flipping component 301 to make the flipping component 301 press the tower member, reducing the moving space of the tower member, thereby reducing shaking and improving the limiting effect by increasing friction.

[0037] Specifically, the limiting frame 101 includes a frame body 101a, an entrance 101b opened on the side of the frame body 101a, and an active cavity 101c opened on the frame body 101a, so that the limiting frame 101 is shaped like a "0" with an opening on the side; wherein, the height of the entrance 101b is less than half of the active cavity 101c, and the size setting of the entrance 101b can prevent the containing frame 201 from detaching, and the containing frame 201 occupies half of the space in the active cavity 101c. The tower material enters the containing frame 201 through the entrance 101b, and the containing frame 201 can move up and down in the active cavity 101c.

[0038] Furthermore, the switch assembly 102 includes guide rails 102a arranged on both sides of the limit frame 101, the sliding frame 102b can slide up and down along the guide rails 102a, the sliding frame 102b slidably connected to the guide rails 102a, wherein the sliding frame 102b is a "J"-shaped structure, and the bottom of the sliding frame 102b is provided with a warped edge, and an anti-slip plate 102c is arranged on the guide rail 102a, wherein the anti-slip plate 102c can limit the warped edge of the sliding frame 102b, thereby limiting the upward movement range of the sliding frame 102b, and a reset spring 102d connected to the sliding frame 102b and the anti-slip plate 102c, when the sliding frame 102b slides upward along the guide rail 102a, the reset spring 102d is stretched, and a pull ring 102e is arranged on the sliding frame 102b.

[0039] Furthermore, the power assembly 103 includes a mounting plate 103a, wherein the mounting plate 103a can be installed on the bottom of the drone by screws, an electric push rod 103b is arranged on the mounting plate 103a, and an electric clamp 103c is connected to the electric push rod 103b. The staff can remotely control the extension and retraction of the electric push rod 103b, thereby adjusting the position of the electric clamp 103c, and then remotely control the electric clamp 103c to extend into the pull ring 102e and close it.

[0040] Operation process: the staff passes the safety rope through the fixed pulley 104, installs the mounting plate 103a on the bottom of the drone through screws, flies the drone to the top of the device through remote control, remotely controls the electric push rod 103b to extend and retract, adjusts the electric clamp 103c to the position of the pull ring 102e, then remotely controls the electric clamp 103c to extend into the pull ring 102e and close it, and the drone carries the device to the top of the tower pole;

[0041] During the flight of the drone, due to the deadweight of the device and the safety rope, the guide rail 102a and the limit frame 101 slide downward relative to the sliding frame 102b until the warped edge of the sliding frame 102b abuts against the anti-slip plate 102c. At this time, the entrance 101b of the limit frame 101 is exposed, and the return spring 102d is stretched. When the sliding frame 102b and the limit frame 101 move in opposite directions, the accommodating frame 201 moves to the bottom of the active cavity 101c through the lifting assembly 202, and the drone flies to the tower material position at the top of the tower pole. The staff inserts the tower material into the accommodating frame 201 through remote operation. When the tower material is inserted into the accommodating frame 201, the tower material abuts against the flip assembly 301, thereby causing the flip assembly 301 to rotate, and the fitting assembly 302 pushes the rotated flip assembly 301, so that the flip assembly 301 squeezes the tower material, reducing the space of the tower material in the accommodating frame 201, thereby reducing shaking, and improving the limiting effect by increasing friction.

[0042] The electric clamp 103c is remotely operated to release the pull ring 102e. At this time, the reset spring 102d returns to its original state and drives the sliding frame 102b and the limiting frame 101 to move toward each other. At this time, the sliding frame 102b moves down to close the entrance 101b. The sliding frame 102b and the limiting frame 101 form a closed space, which can prevent the tower material from being separated from the device and provide bottom-up safety protection. When the sliding frame 102b moves down, it will drive the lifting component 202 to work. The lifting component 202 drives the accommodating frame 201 to move to the top of the active cavity 101c. At this time, the accommodating frame 201 and the limiting frame 101 form a closed space on the tower material to prevent the tower material from being separated from the device. The unlocking can be completed by pulling the pull ring 102e by the drone;

[0043] The two ends of the safety rope are fixed on the ground. At this time, the middle section of the safety rope is hung on the fixed pulley 104, and the safety rope forms a triangle. Then, a wire rope self-locking device is installed on the safety rope. The staff wears the safety belt and connects the wire rope self-locking device to the safety belt. They climb to the top along the tower pole to carry out maintenance and inspection work. This device provides a reliable hanging point for the safety rope, and the hanging point is installed and disassembled by a drone, which improves the installation speed. The staff climbs the tower pole with the safety rope, which improves safety.

[0044] Example 2

[0045] Reference Figure 5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the lifting component 202 includes a mounting groove 202a opened on the limiting frame 101, a rotating rod 202b rotatably set in the mounting groove 202a, and a guide ball 202c connected to the rotating rod 202b, wherein the guide ball 202c is located in the annular groove 202d of the rotating rod 202b, and the lifting component 202 is provided with at least four to ensure the lifting effect.

[0046] Specifically, an inclined annular groove 202d is provided on the circumference of the rotating rod 202b, two guide balls 202c are provided and are respectively connected to the containing frame 201 and the sliding frame 102b, and the two guide balls 202c are respectively located at the highest point and the lowest point of the annular groove 202d.

[0047] The rest of the structure is the same as that of Example 1.

[0048] Operation process: When the sliding frame 102b moves, it will move with the guide ball 202c. Since the guide ball 202c is set in the annular groove 202d, the movement of the guide ball 202c drives the rotating rod 202b to rotate through the annular groove 202d, and then drives the containing frame 201 to move. When the sliding frame 102b moves up, the containing frame 201 moves down. When the sliding frame 102b moves down, it will drive the containing frame 201 to move up, so as to control whether the tower material is covered.

[0049] Example 3

[0050] Reference Figure 6-Figure 7 , which is the third embodiment of the present invention. This embodiment is different from the above embodiments in that the flip assembly 301 includes a support frame 301a arranged on the accommodating frame 201, wherein the support frame 301a is provided with two, and the lower surface of the inner wall of the accommodating frame 201 is provided with a limiting plate 301b rotatably connected to the support frame 301a, wherein the limiting plate 301b will rotate when subjected to force, and a rubber pad is provided on one surface of the limiting plate 301b.

[0051] Specifically, the support frame 301a is provided with a rotating groove 301c and a guide groove 301d, the rotating groove 301c is provided with an opening, the rotating shaft of the limit plate 301b is located in the rotating groove 301c, wherein the limit plate 301b rotates around the rotating groove 301c, the guide groove 301d is composed of an arc groove at one end and a straight groove at the other end, the guide groove 301d is used to assist the rotation of the rotating plate, and a guide rod 301e is provided at the bottom end of the limit plate 301b, the limit plate 301b slides in the guide groove 301d through the guide rod 301e, and the setting of the opening and the straight groove enables the limit plate 301b to be detached from the support frame 301a when it is at a specific angle.

[0052] Furthermore, the fitting component 302 includes a guide cylinder 302a arranged on the containing frame 201, a telescopic rod 302b slidably connected to the inner wall of the guide cylinder 302a, wherein the telescopic rod 302b slides up and down along the guide cylinder 302a, a top plate 302c connected to the telescopic rod 302b, and a fitting spring 302d sleeved on the surrounding sides of the guide cylinder 302a and the telescopic rod 302b, wherein the fitting spring 302d is in a compressed state, so that the top plate 302c can always be against the limit plate 301b.

[0053] Furthermore, one end of the fitting spring 302d is connected to the containing frame 201, and the other end of the fitting spring 302d is connected to the top plate 302c.

[0054] The rest of the structure is the same as that of Example 2.

[0055] Operation process: When the device is not put on the tower material, the guide rod 301e on the bottom end of the limit plate 301b is located at the deepest part of the arc groove. The arc groove limits the guide rod 301e from the top, and the fitting spring 302d makes the top plate 302c move up. The top plate 302c limits the guide rod 301e from the bottom, so that the limit plate 301b maintains the current inclination angle; when the tower material is to be put into the device, the tower material squeezes the limit plate 301b. At this time, the limit plate 301b rotates clockwise, the fitting spring 302d is squeezed and the top plate 302c moves down. As the tower material continues to enter the containing frame 201, the guide rod 301e moves from the depth of the arc groove to the intersection of the arc groove and the straight groove, and the side of the limit plate 301b with the rubber pad gradually faces the tower material. At this time, the fitting spring 302d drives the top plate 302c to move upward, the rotating shaft of the limit plate 301b moves up from the opening, and the guide rod 301e moves up from the straight groove, so that the limit plate 301b pops up from the support frame 301a, squeezing the tower material, reducing the moving space of the tower material, thereby reducing shaking, and improving the limiting effect by increasing friction.
