[0030] In actual use, the traction unit is pre-set on a transfer device (such as an aerial work robot, an aerial work vehicle, an unmanned aerial vehicle, etc.), and then the traction unit is transferred to the designated fire connection position by the transfer device. Before the transfer, the free end of the traction line needs to be pre-connected with the in-place detection part 2 of the drain line clamping mechanism 10, and before the traction operation, the end of the drain line needs to be clamped and fixed in advance by the opening and closing clamp 3, and the corresponding clamping force is adjusted by its sliding position relative to the sliding seat 1, so as to clamp the drain line on the drain line clamping mechanism 10; the traction line is reeled in by the traction unit to transfer the drain line to the designated fire connection position, and when the drain line needs to be removed, the transfer device The drainage line can be taken out by a grasping device (such as a robotic arm, a grasping clamp, etc.), and the opening and closing clamp 3 is pushed to slide toward the in-place detection part 2 until the opening and closing clamp 3 touches the detection end of the in-place detection part 2. At this time, it is determined that the opening and closing clamp 3 is fully opened, that is, in a released state. The in-place detection part 2 can send an in-place signal to the grasping device, so that the grasping device takes the drainage line out of the opening and closing clamp 3.

In addition, the drainage line clamping mechanism 10 cooperates with the traction unit to realize autonomous transfer of the drainage line, thereby improving the stability of the drainage line during the transfer process.

[0031] It should be noted that the traction unit is an existing hoisting equipment structure, and its specific structure and working principle are all existing technologies and will not be described in detail here.

[0032] like Figures 1 to 8As shown, further, the opening and closing chuck 3 includes an opening and closing portion 31 and two slide portions 32 respectively arranged on both sides of the opening and closing portion 31, and a clamping groove 33 is provided in the opening and closing portion 31 and is open to one side and can be opened and closed; the sliding seat frame 1 includes two seat plates 11 in opposite positions, and the two seat plates 11 are connected by an end cover 12 at one end close to the opening and closing chuck 3, and the end cover 12 is provided with a wire inlet 13 at the opening corresponding to the clamping groove 33; the seat plate 11 is provided with a slide groove 14, and the two sides of the opening and closing portion 31 are connected to the slide groove 14 on both sides respectively through the slide portion 32. 4 sliding connection, the two sides of the end cover 12 are connected to the slide plate portion 32 through the stretching portion 34 respectively, the opening and closing portion 31 is located between the two seat plates 11; the in-place detection portion 2 is located between the other ends of the two seat plates 11; when the drainage line needs to be clamped, the opening and closing portion 31 is initially in an open state, and it is located at one end close to the in-place detection portion 2. At this time, the operator can insert at least part of the drainage line into the clamping groove 33. At this time, the stretching portion 34 is in a stretched state, and then the tension of the stretching portion 34 is used to slide the opening and closing portion 31 toward the end cover 12 to open it. The clamping groove 33 is gradually narrowed to gradually clamp the drainage wire in the closing portion 31, and the stretching portion 34 has entered the tightening state, providing a tightening tension to both sides of the slide portion 32, so that the closing portion 31 is maintained in the clamping state, thereby completing the entire clamping action; When the drainage needs to be taken out, the operation and maintenance personnel hold the wire body of the drainage line and push it toward the in-place detection part 2 until the end face of the drainage line is supported against the bottom of the opening and closing part 31, so that the opening and closing part 31 slides toward the in-place detection part 2. During the sliding process, the opening and closing part 31 is guided by the slide plate part 32 and the slide groove 14. When the opening and closing part 31 slides back to the predetermined position, it will open to release the drainage line from the clamping groove 33. At the same time, when one end face of the opening and closing part 31 is supported against the in-place detection part 2, it indicates that the opening and closing part 31 is fully opened, thereby completing the entire line removal action.

[0033] like Figures 1 to 8As shown, further, the opening and closing portion 31 includes two movable plates 311 arranged opposite to each other, a movable groove 312 is formed between the two movable plates 311, one end of the two movable plates 311 is connected by a rotating shaft 313, and an opening and closing portion 314 is rotatably connected to the rotating shaft 313, two clamping blocks 315 are provided between the other ends of the two movable plates 311, the two clamping blocks 315 are rotatably connected to the opening and closing portion 314 through connecting plates 317 respectively, and the opening and closing portion 314 is used to control the opening and closing movement of the two clamping blocks 315, the two clamping blocks 315 are at least partially located in the movable groove 312, and the clamping groove 33 is located between the two clamping blocks 315; a baffle 316 is provided at one end of the clamping block 315 close to the opening and closing portion 314, and the baffle 316 extends into the clamping groove 33.

[0036] When the opening and closing part 31 performs the line clamping action, the operation and maintenance personnel twist the opening and closing part 314 by pressing the two clamping blocks 315, so that the two clamping blocks 315 are clamped and closed, and then pull the movable plate 311 and the two clamping blocks 315 in the direction of the end cover 13. During the sliding process, the movable plate 311 is guided by the slide plate part 32 and the slide groove 14 until the two clamping blocks 315 are pulled to the predetermined position, so that the drainage line is clamped in the clamping groove 33. At this time, the stretching part 34 has entered the tightening state, providing a tightening pulling force for the two movable plates 311 to keep the two clamping blocks 315 in the clamping state, thereby completing the entire clamping action.

[0037] When the opening and closing part 31 is performing the line-taking action, the operation and maintenance personnel hold the line body of the drainage line and push it toward the in-place detection part 2 until the end face of the drainage line is supported by the baffle 316, and use the resistance of the baffle 316 to drive the clamping block 315 and the movable plate 311 to slide toward the in-place detection part 2. During the sliding process, the movable plate 311 is guided by the slide plate part 32 and the slide groove 14. When the two clamping blocks 315 slide back to the predetermined position, they will open under the action of the opening and closing part 314 to release the drainage line from the clamping groove 33. At the same time, when one end face of the opening and closing part 314 is supported by the in-place detection part 2, it indicates that the opening and closing part 31 is fully opened, thereby completing the entire line-taking action.

[0038] It should be noted that the stretching portion 34 is an existing workpiece with a stretching and rebounding function, such as a spring or a tension spring.

[0040] It should be noted that the torsion springs in the first rotating block 3141 and the second rotating block 3142 have opposite torsional directions.

[0044] like Figures 1 to 8 As shown, further, the positioning plug 21 includes a plug rod 211 and a connector 212, the connector 212 is connected to the free end of the traction line, and the connector 212 is threadedly connected to one end of the plug rod 211, and the other end of the plug rod 211 is connected to the bottom of the position detection unit 22; by setting the positioning plug 21 as a split structure, the connection or disassembly of the traction line can be facilitated, and when disassembling, the disassembly and assembly can be completed by twisting the connector 212, and the entire disassembly and assembly process is extremely convenient.

[0047] In summary, before the traction operation, the end of the drain line needs to be clamped and fixed in advance by the opening and closing clamp 3, and the corresponding clamping force is adjusted by the sliding position relative to the sliding seat, so that the drain line is clamped on the drain line clamping mechanism 10; the traction line is reeled in by the traction unit to transfer the drain line to the designated fire connection position. When the drain line needs to be removed, the transfer device can take out the drain line through the gripping device, and push the drain line to make the opening and closing clamp 3 slide in the direction of the in-place detection part 2 until the opening and closing clamp is closed. When the head 3 touches the detection end of the in-place detection part 2, it is determined that the opening and closing clamp 3 is fully opened, that is, in a released state. The in-place detection part 2 can send an in-place signal to the gripping device, so that the gripping device takes out the drainage wire from the opening and closing clamp 3. In this way, it can be ensured that the drainage wire is taken out only after the opening and closing clamp 3 enters the released state, avoiding unnecessary damage to the drainage wire. In addition, the drainage wire clamping mechanism 10 cooperates with the traction unit to realize autonomous transfer of the drainage wire, thereby improving the stability of the drainage wire during the transfer process.
