As shown in fig. 1, a hanging shaft 14 is disposed between the two second wing plates 1113 below the second connecting plate 113, and the hanging shaft 14 is fixedly connected with one end of the safety rope.
Further, as shown in fig. 4, the guide holder 12 determines the maximum opening angle of the first opening and closing arm 31 and the second opening and closing arm 32. Namely, when the first opening and closing arm 31 and the second opening and closing arm 32 respectively abut against two sides of the guide seat 12, the first opening and closing arm 31 and the second opening and closing arm 32 are at the maximum opening angle.
Further, as shown in fig. 13 and 14, the upper end portion of the first opening and closing arm 31 is provided with a first abutment surface 316, the upper end portion of the second opening and closing arm 32 is provided with a second abutment surface 326, and when the first opening and closing arm 31 and the second opening and closing arm 32 are in the closed state, the first abutment surface 316 and the second abutment surface 326 abut against each other and are located below a plane formed by the axis of the first hinge shaft 41 and the axis of the second hinge shaft 42. The abutting first and second abutment surfaces 316, 326 cooperate to limit the swinging of the first and second arms 31, 32 toward each other, so that the first and second arms 31, 32 are in a stable closed state.
Further, as shown in fig. 4, an elastic member for preventing the sliding hinge shaft 22 from moving downward with respect to the driving pin 21 is provided between the driving pin 21 and the sliding hinge shaft 22.
As a specific embodiment, as shown in fig. 3, 5, 7, 11 and 12, a guide post 23 is disposed in the sliding slot 211 of the driving pin 21 in this embodiment, the guide post 23 passes through the sliding hinge shaft 22, and a guide hole 221 for accommodating the guide post 23 is disposed on the sliding hinge shaft 22. The guide post 23 is sleeved with a spring 24 below the sliding hinge shaft 22.
The reason for this design is that there is an unreliability in inserting the driving pin 21 into the first pin hole 313 and the second pin hole 323 by the gravity of the driving pin 21 itself, and there is a possibility that the driving pin 21 cannot be inserted into the first pin hole 313 and the second pin hole 323 due to a large friction force or the like. By providing the spring 24, when the first pin hole 313 and the second pin hole 323 are aligned, the transmission pin 21 can be pressed into the first pin hole 313 and the second pin hole 323 by the elastic force of the spring 24, improving the reliability of locking.
As a specific embodiment, a threaded hole 212 is disposed below the sliding slot 211 in the driving pin 21 in this embodiment, and an inserting hole 213 is disposed on the upper sidewall of the sliding slot 211. The guide post 23 sequentially comprises a first shaft section 231 and a second shaft section 232 from bottom to top, and the diameter of the first shaft section 231 is larger than that of the second shaft section 232. The first shaft section 231 is provided with external threads matched with the threaded hole 212, locking of the guide post 23 can be achieved through threaded matching between the first shaft section 231 and the threaded hole 212, and the upper end of the second shaft section 232 is inserted into the inserting hole 213. The spring 24 is sleeved on the second shaft section 232, the upper end of the spring 24 abuts against the sliding hinge shaft 22, and the lower end of the spring 24 abuts against a step surface between the first shaft section 231 and the second shaft section 232. A plugging slot 2311 matched with the spanner is arranged on the lower end surface of the first shaft section 231.
Further, a hanging ring 6 is arranged at the upper end of the transmission pin 21.
As a specific embodiment, as shown in fig. 4 and 6, a stud 61 is disposed at the lower end of the suspension ring 6 in this embodiment, and a screw hole matched with the stud 61 is disposed on the upper end surface of the driving pin 21.
The process of hanging the safety rope is as follows:
First, the safety rope is connected and fixed to the hitch shaft 14, and the hanging ring 6 is connected to the unmanned aerial vehicle. Since the lifting ring 6 is connected with the unmanned aerial vehicle at this time, the whole fixing frame 1 moves downwards relative to the driving pin 21, and the driving pin 21 moves upwards relative to the fixing frame 1. When the driving pin 21 moves upwards relative to the fixing frame 1, the first opening and closing arm 31 and the second opening and closing arm 32 are pulled by the first connecting rod 51 and the second connecting rod 52, so that the first opening and closing arm 31 and the second opening and closing arm 32 are opened until the first opening and closing arm 31 and the second opening and closing arm 32 respectively abut against two sides of the guide seat 12, and the first opening and closing arm 31 and the second opening and closing arm 32 are in an opened state as shown in fig. 4.
Secondly, the iron tower hanging frame is placed on the hanging transverse material 7 through the unmanned aerial vehicle. After the fixing frame 1 is placed on the hooking cross bar 7, the unmanned aerial vehicle descends, and in the descending process, the first opening and closing arm 31 and the second opening and closing arm 32 swing downwards (swing towards each other) under the action of gravity of the unmanned aerial vehicle, until the first pin hole 313 of the first opening and closing arm 31 and the second pin hole 323 of the second opening and closing arm 32 are aligned, namely, the state shown in fig. 13. Then the unmanned aerial vehicle continues to descend, because the first opening and closing arm 31 and the second opening and closing arm 32 are in the stable closed state (i.e. cannot swing towards each other), when the unmanned aerial vehicle continues to descend, the spring 24 is released, and the driving pin 21 is inserted into the first pin hole 313 and the second pin hole 323 under the action of the spring 24, i.e. the state shown in fig. 15.
Thirdly, the unmanned aerial vehicle is separated from the hanging ring 6, and the hanging of the safety rope is completed.
The same principle is adopted when the safety rope is detached, after the unmanned aerial vehicle is connected with the lifting ring 6, in the lifting process, the spring 24 is compressed firstly because the elastic force of the spring 24 is insufficient to support the self gravity of the hanging frame, and the transmission pin 21 moves upwards relative to the sliding hinge shaft 22 until the sliding hinge shaft 22 is pressed on the lower end part of the sliding groove 211. At this time, the unmanned aerial vehicle continues to ascend, and the first connecting rod 51 and the second connecting rod 52 at the two sides are pulled through the sliding pin shaft, so that the first opening and closing arm 31 and the second opening and closing arm 32 are opened. After the first opening and closing arm 31 and the second opening and closing arm 32 are completely opened, the unmanned aerial vehicle continues to ascend, and the whole hanging frame can be taken down from the hanging transverse material 7.
Example two
An elastic piece is arranged between the transmission pin 21 and the guide seat 12. The elastic member is a tension spring, one end of the tension spring is hooked on the transmission pin 21, and the other end of the tension spring is hooked on the bottom plate 121 of the guide seat 12.
As a specific embodiment, two tension springs are disposed between the driving pin 21 and the guide seat 12 in this embodiment, and the two tension springs are symmetrically disposed.
The rest of the structure is the same as that of the first embodiment.
On the basis of the embodiment provided by the application, other embodiments obtained by combining, splitting, recombining and other means of the embodiment of the application do not exceed the protection scope of the application.
The foregoing detailed description of the embodiments of the present application has been provided for the purpose of illustrating the purposes, technical solutions and advantages of the embodiments of the present application, and is not intended to limit the scope of the embodiments of the present application, i.e., any modifications, equivalent substitutions, improvements, etc. made on the basis of the embodiments of the present application should be included in the scope of the embodiments of the present application.
