Fig. 1 illustrates a helicopter payoff trolley that is used to deploy a guide line 100.

Specifically, the helicopter pay-off tackle comprises a frame body 10, wherein the frame body 10 comprises a first frame body 11 and a second frame body 12, the first frame body 11 and the second frame body 12 are oppositely arranged, and the second frame body 12 is located on the right side of the first frame body 11.

Further, the second frame 12 includes a rotating frame 121 and a connecting frame 122, the rotating frame 121 is connected to the connecting frame 122, and the rotating frame 121 and the first frame 11 form a first opening 101 for the guide rope 100 to pass through.

Specifically, the helicopter pay-off tackle also includes an extension bar 20, and the extension bar 20 is detachably attached to the rotating frame 121 and is adjacent to the first opening 101, so that the guide rope 100 passes through the first opening 101 along the surface of the extension bar 20.

Specifically, the helicopter payoff tackle includes a rolling assembly 30, and both ends of the rolling assembly 30 are respectively disposed on the first frame body 11 and the connecting frame 122, and are used for placing the guide rope 100.

Further, the rolling assembly 30 includes a rolling body 31 and a support member 32, the support member 32 is sleeved with the rolling body 31, wherein one end of the support member 32 is mounted on the first frame 11, the other end is mounted on the connecting frame 122, and the support member 32 limits the rolling body 31 between the first frame 11 and the second frame 12.

Further, the rolling body 31 has at least one groove 311, and the groove 311 is used for placing the guide rope 100. It is worth mentioning that, in order to keep the helicopter line tackle stable during the helicopter line laying process, the guide rope 100 needs to be placed in the middle groove 311 to keep the helicopter line tackle stable at the left and right ends.

Specifically, fig. 2 to 3 illustrate a use process of the second frame 12. In use, the rotating frame 121 is manually opened to rotate the rotating frame 121 downwards until the rotating frame 121 and the connecting frame 122 are folded. Since the extension bar 20 may interfere with the rolling assembly 30, the extension bar 20 may be manually removed from the rotating frame 121 by a human when the rotating frame 121 is opened. Then, the guide rope 100 placed in the groove 311 is manually taken out.

It is worth mentioning that when the helicopter pay-off tackle needs maintenance and repair, the rotating frame 121 can be manually opened and the helicopter pay-off tackle can be maintained and repaired conveniently.

The existing helicopter line laying tackle needs to put the guide rope 100 into the tackle through manpower, which is troublesome. There is therefore a need for improvements in the helicopter payoff block.

Further, the helicopter paying-off trolley comprises a first guide member 40 and a second guide member 50, wherein the first guide member 40 is rotatably mounted on the first frame body 11, the second guide member 50 is rotatably mounted on the rotating frame 121, a guide channel 102 is formed between the first frame body 11 and the rotating frame 121, and the guide channel 102 is communicated with the first opening 101. Further, one end of the first guide member 40 and one end of the second guide member 50 are respectively close to the groove 311, so that the guide rope 100 slides into the groove 311 along the surface of the second guide member 50. It is worth mentioning that the guide channel 102 defines the position where the guide rope 100 falls, so that the guide rope 100 falls into the groove 311 in the middle of the rolling body 31, thereby ensuring that the helicopter payoff tackle is relatively smooth.

It should be noted that, by means of the first guide 40 and the second guide 50, the helicopter pay-off tackle can conveniently feed the guide rope 100 into the groove 311 in the middle of the rolling body 31.

Further, when the guide rope 100 enters the guide channel 102 through the first opening 101, the guide rope 100 slides along the surface of the second guide 50 into the groove 311.

Further, the self-locking structure 60 comprises a rotating rod 61 and an elastic member 62, the rotating rod 61 is close to the first opening 101 and is disposed on the first frame body 11, wherein the elastic member 62 is mounted on the rotating rod 61, and one end of the elastic member 62 abuts against the surface of the rotating rod 61. Further, one end of the rotating rod 61 abuts against the rotating frame 121, thereby closing the first opening 101. Further, the elastic member 62 may be further implemented as a return spring.

It is worth mentioning that the rotating lever 61 is pressed by the guide rope 100, and then the elastic member 62 mounted on the rotating lever 61 is found to be deformed, and at the same time, the rotating lever 61 is rotated by a certain angle. When the rotating rod 61 is forced to rotate, the rotating rod 61 and the rotating frame 121 form a second opening 103, and the second opening 103 is respectively communicated with the first opening 101 and the guide channel 102. As shown in fig. 4, the width of the second opening 103 is L1. In other words, when the rotating lever 61 is not pressed by the guide rope 100, one end of the rotating lever 61 abuts against the rotating frame 121, and the width of the second opening 103 is 0. When the rotating lever 61 is pressed by the guide rope 100 and rotates, the width of the second opening 103 is increased. In addition, when the width of the second opening 103 is L1, the cross-sectional diameter of the guide cord 100 is larger than the width L1 of the second opening 103, and thus the guide cord 100 cannot pass through the second opening 103. The guide rope 100 continuously applies pressure to the rotation lever 61 due to gravity, and the width of the second opening 103 is continuously increased. As shown in fig. 5, the width of the second opening 103 is L2, and the width L2 of the second opening 103 is greater than the cross-sectional diameter of the guide cord 100, so that the guide cord 100 passes through the second opening 103 and enters the guide channel 102.

Further, the self-locking structure 60 further includes a limiting block 63, and the limiting block 63 is installed on the first frame body 11 and is close to the first opening 101. Further, the other end of the elastic element 62 abuts against the stop block 63. It is worth mentioning that one end of the elastic member 62 abuts against the rotating lever 61, and the other end abuts against the stopper 63, and when the rotating lever 61 is pressed by the guide rope 100 to rotate, the elastic member 62 is forced to deform. Further, when the guide rope 100 passes through the second opening 103, the rotating rod 61 is not pressed by the guide rope 100, and at this time, because the elastic member 62 is compressed and deformed by the force, the elastic member 62 applies pressure to the rotating rod 61, and the rotating rod 61 is reset to close the first opening 101.

The use of the helicopter payoff block is illustrated in fig. 6-7. In the using process, the guide rope 100 is manually hung on the extension bar 20, and the extension bar 20 is under the action of gravity, so that the extension bar 20 slides along the surface of the extension bar 20 to the first opening 101 until the guide rope 100 contacts the rotating rod 61. When the guide rope 100 collides with the rotating lever 61, the guide rope 100 applies pressure to the rotating lever 61, and the rotating lever 61 is rotated by a certain angle, so that the guide rope 100 passes through. When the guide rope 100 enters the guide channel 102, the guide rope 100 hangs on the surface of the second guide 50 due to gravity and slides down along the surface of the second guide 50 until the guide rope 100 enters the groove 311 in the middle of the rolling body 31. In addition, when it is necessary to remove the guide rope 100, the rotating frame 121 may be manually opened by a human, and then the first guide member 40 and the second guide member 50 may be manually pulled forward or backward by a human. Finally, the guide rope 100 placed in the groove 311 is manually taken out.
