[0046] Please refer to Figure 1 and Figure 2 FIG1 shows a schematic diagram of the structure of a new type of multi-scenario soft ladder head based on an automatic unlocking device in an embodiment of the present application. A new type of multi-scenario soft ladder head 1000 based on an automatic unlocking device provided in an embodiment of the present application comprises: a ladder head frame 1100, at least two hooks 1200 and a plurality of self-locking mechanisms 1300, at least two hooks 1200 are located on one side of the ladder head frame 1100 along a first direction and arranged along a second direction, the hooks 1200 are connected to the ladder head frame 1100, a plurality of self-locking mechanisms 1300 are arranged corresponding to the hooks 1200, the self-locking mechanism 1300 comprises a self-locking hook 1310 and a hook mouth stop arm 1320, and the bending direction of the self-locking hook 1310 and the hook 1200 is In the same direction, the self-locking hook 1310 is arranged on one side of the corresponding hook 1200 along the second direction, and a blocking block 1313 is provided on the self-locking hook 1310. The hook mouth blocking arm 1320 is rotatably connected to the self-locking hook 1310, and a card slot 1323 for engaging with the blocking block 1313 is provided on the hook mouth blocking arm 1320. The first direction and the second direction are arranged to intersect. During the process of the self-locking hook 1310 being hooked with the power transmission line (not shown), the hook mouth blocking arm 1320 is configured to rotate under the push of the power transmission line to close the hook mouth of the self-locking hook 1310, and the card slot 1323 is engaged with the blocking block 1313.

[0047] In the present embodiment, a new type of multi-scenario soft ladder head 1000 based on an automatic unlocking device, a soft ladder (not shown) is connected to a ladder head frame 1100, and the ladder head frame 1100 is hung on a power transmission line through a hook 1200. When the hook 1200 is hung on the power transmission line, part of the power transmission line enters the hook mouth of the hook 1200, and the other part enters the hook mouth of the self-locking hook 1310 in the self-locking mechanism 1300. In this process, the part of the power transmission line entering the hook mouth of the self-locking hook 1310 pushes the hook mouth blocking arm 1320 in the self-locking mechanism 1300 to rotate relative to the self-locking hook 1310, so that the hook mouth blocking arm 1320 closes the hook mouth of the self-locking hook 1310. When the hook mouth stop arm 1320 closes the hook mouth of the self-locking hook 1310, the power transmission line entering the hook mouth of the self-locking hook 1310 is limited in the closed area surrounded by the self-locking hook 1310 and the hook mouth stop arm 1320, and the block 1313 provided on the self-locking hook 1310 is engaged with the slot 1323 provided on the hook mouth stop arm 1320, so as to limit the rotation of the hook mouth stop arm 1320 and prevent the hook mouth stop arm 1320 from rotating relative to the self-locking hook 1320 in the direction of opening the hook mouth of the self-locking hook 1320 under the elasticity and shaking of the power transmission line, so as to prevent the multi-scenario new soft ladder head 1000 based on the automatic unlocking device from falling off from the power transmission line under the elasticity and shaking of the power transmission line when the staff go up and down the soft ladder.

[0048] To summarize, in the multi-scenario novel soft ladder head 1000 based on the automatic unlocking device in this embodiment, when the hook 1200 is hooked with the power transmission line, the power transmission line part will push the hook mouth blocking arm 1320 to close the hook mouth of the self-locking hook 1310 in the self-locking mechanism 1300 during the process of entering the hook mouth of the self-locking hook 1310. When the staff go up and down the soft ladder, the hook mouth of the self-locking hook 1310 is always in a self-locking closed state, which avoids the staff from climbing up the soft ladder to manually self-lock and close the hook mouth of the self-locking hook 1310. The operation is simple and efficient, and the occurrence of high-altitude falling accidents is prevented.

[0049] Please refer to Figure 1 and Figure 2 In some embodiments, the hook mouth stop arm 1320 includes a pressing portion 1321 and a locking portion 1322 that are fixedly connected, and a rotating shaft (not shown) passing through the connection between the pressing portion 1321 and the locking portion 1322, the rotating shaft is rotatably connected to the self-locking hook 1310, and a card slot 1323 is provided on the pressing portion 1321, the pressing portion 1321 is located in the hook mouth of the self-locking hook 1310, when the pressing portion 1321 is in a naturally drooping state, the locking portion 1322 is configured to open the hook mouth of the self-locking hook 1310, when the pressing portion 1321 rotates relative to the self-locking hook 1310 under the push of the power transmission line, the locking portion 1322 rotates driven by the pressing portion 1321 and closes the hook mouth of the self-locking hook 1310.

[0050] In this embodiment, when the staff removes the new multi-scenario soft ladder head 1000 based on the automatic unlocking device from the power transmission line, the top pressure part 1321 rotates around the axis of the rotating shaft relative to the self-locking hook 1310 under the action of its own gravity until it returns to a naturally drooping state. During this process, the locking part 1322 moves synchronously under the drive of the top pressure part 1321 and opens the hook of the self-locking hook 1310, so that the staff can subsequently hang the new multi-scenario soft ladder head 1000 based on the automatic unlocking device on the power transmission line again.

[0051] When the staff hooks the multi-scenario new soft ladder head 1000 based on the automatic unlocking device on the power line, part of the power line enters the hook mouth of the hook 1200, and the other part enters the hook mouth of the self-locking hook 1310. The part of the power line entering the hook mouth of the self-locking hook 1310 contacts the pressing part 1321 and pushes the pressing part 1321 to rotate relative to the self-locking hook 1310 around the axis of the rotating shaft; in this process, the locking part 1322 is driven by the pressing part 1321 to rotate relative to the self-locking hook 1310. The self-locking hook 1310 is connected to the locking portion 1322 of the self-locking hook 1320 by the locking block 1313 provided on the self-locking hook 1310 and the locking groove 1323 provided on the pressing portion 1321 to limit the rotation of the pressing portion 1321, thereby preventing the pressing portion 1321 from driving the locking portion 1322 to rotate relative to the self-locking hook 1320 in the direction of opening the hook mouth of the self-locking hook 1320 under the elasticity and shaking of the transmission line.

[0052] In some embodiments, the axis of the rotating shaft is parallel to the second direction.

[0053] In some embodiments, the self-locking hook 1310 and the hook 1200 are bent in a direction away from the ladder head frame 1100 .

[0054] Please refer to Figure 1 and Figure 2 In some embodiments, the projection of a perpendicular line between one end of the pressing portion 1321 away from the rotating shaft and the axis of the rotating shaft on a virtual plane (not shown) intersects with the projection of a perpendicular line between one end of the locking portion 1322 away from the rotating shaft and the axis of the rotating shaft on the virtual plane, and the virtual plane is perpendicular to the rotating shaft.

[0055] In this embodiment, the projection of the vertical line between the end of the pressing part 1321 away from the rotating shaft and the axis of the rotating shaft on the virtual plane is intersected with the projection of the vertical line between the end of the locking part 1322 away from the rotating shaft and the axis of the rotating shaft on the virtual plane. When the transmission line pushes the pressing part 1321 to rotate relative to the self-locking hook 1310 around the axis of the rotating shaft, the locking part 1322 can close the hook of the self-locking hook 1310 when it rotates driven by the pressing part 1321.

[0056] Please refer to Figure 1 and Figure 2 In some embodiments, the side of the pressing portion 1321 away from the locking portion 1322 is a locking surface 1321-1, and a locking groove 1323 is provided on the locking surface 1321-1. The locking groove 1323 extends toward the rotating shaft from the side of the locking surface 1321-1 away from the rotating shaft along the bending direction of the locking surface 1321-1. The groove wall of the groove 1323 close to the rotating shaft along its own extension direction is configured to abut against the locking block 1313 when the locking portion 1322 closes the hook mouth of the self-locking hook 1310.

[0057] In this embodiment, the power transmission line pushes the pressing part 1321 to rotate around the axis of the rotating shaft relative to the self-locking hook 1310, and the pressing part 1321 drives the locking part 1322 to move synchronously. During this process, the hook mouth of the self-locking hook 1310 is gradually closed by the locking part 1322, and the card slot 1323 on the card surface 1321-1 moves toward the direction close to the card block 1313, and when the locking part 1322 completely closes the hook mouth of the self-locking hook 1310, it abuts against the groove wall on one side of the card slot 1323 close to the rotating shaft along its own extension direction, thereby limiting the movement of the pressing part 1321 and preventing the pressing part 1321 from rotating relative to the self-locking hook 1320 in the direction of driving the locking part 1322 to open the hook mouth of the self-locking hook 1320 under the elasticity and shaking of the power transmission line.

[0058] Please refer to Figure 1 and Figure 2 In some embodiments, the self-locking hook 1310 includes an unlocking component 1330, and the unlocking component 1330 includes a first connecting rod 1331, the first connecting rod 1331 extends along a first direction, the first connecting rod 1331 is slidably connected to the self-locking hook 1310 along the first direction, and the block 1313 is connected to the first connecting rod 1331.

[0059] In this embodiment, by setting the first connecting rod 1331 to extend along the first direction, the first connecting rod 1331 is slidably connected to the self-locking hook 1310 along the first direction, and the block 1313 is connected to the first connecting rod 1331. The staff can drive the first connecting rod 1331 to slide relative to the self-locking hook 1310 along the first direction, so that the block 1313 leaves the slot 1323 along the first direction, separates the engagement between the block 1313 and the slot 1323, and releases the movement restriction of the pressing part 1321 by the block 1313, so that the pressing part 1321 can drive the locking part 1322 to rotate relative to the self-locking hook 1320 in the direction of opening the hook mouth of the self-locking hook 1320, so that the staff can remove the new multi-scenario soft ladder head 1000 based on the automatic unlocking device from the power transmission line.

[0060] In some embodiments, a fixing block 1311 is provided at the bending part of the self-locking hook 1310, and a receiving groove 1312 is provided on the side of the fixing block 1311 close to the hook mouth of the self-locking hook 1310, and a clamping block 1313 is located in the receiving groove 1312. One end of the first connecting rod 1331 is connected to the clamping block 1313, and the other end passes through the fixing block 1311 in a direction away from the hook mouth of the self-locking hook 1310, and is slidably connected to the fixing block 1311.

[0061] In some embodiments, a spring (not shown) is disposed in the receiving groove 1312 , and the spring is sleeved on the outer circumference of the first connecting rod 1331 .

[0063] In this embodiment, when the multi-scenario new soft ladder head 1000 based on the automatic unlocking device is to be removed from the power transmission line, the staff connects a soft rope (not shown) to the baffle 1335, applies tension to the soft rope, pulls the baffle 1335 close to the connecting plate 1120, compresses the elastic member 1336 between the connecting plate 1120 and the baffle 1335, and drives the second connecting rod 1332 to move in the first direction through the baffle 1335. The second connecting rod 1332 drives the first connecting rod 1331 to move in the first direction via the connecting rod 1333. The first connecting rod 1331 drives the clamping block 1313 to move away from the clamping slot 1323 in the first direction, thereby separating the clamping block 1313 from the clamping slot 1323, so that the power transmission line can leave the self-locking hook 1310 from the hook mouth of the self-locking hook 1310. In summary, the new multi-scenario soft ladder head 1000 based on the automatic unlocking device in this embodiment can unlock and open the hook of the self-locking hook 1310 without the need for workers to climb onto the soft ladder. The operation is simple and efficient, and the safety risk is small.
