The two return springs 24 are fixedly connected to the top of the fixed transverse plate 13. The lifting plate 2 contacts the top of the hook body 12. A limiting wedge block 3 is provided on one side of the lifting plate 2. The limiting wedge block 3 is slidably connected to the inner wall of the lifting plate 2. A spring piece 31 is fixedly connected between the limiting wedge block 3 and the lifting plate 2. A side groove 112 is provided on the inner wall of the inner groove 111. The limiting wedge block 3 is snap-connected to the inner wall of the side groove 112.

[0017] In this embodiment: the traction body 11 supports the various components of the device, the traction body 11 is connected to the lifting crane through the rope at the top, a gap is set between the hook body 12 and the traction body 11, which is convenient for the hook body 12 to be connected to the hook or rope on the supply, the traction body 11 gives way and slides the lifting plate 2 through the inner groove 111, the lifting plate 2 supports the connecting plate 21, the connecting plate 21 supports the lifting hook plate 22, and the slide groove 121 limits and guides the connecting plate 21 when it slides up and down, preventing the connecting plate 21 from driving the lifting hook plate 22 to deviate and The lifting hook plate 22 is rotated to improve the connection stability between the lifting hook plate 22 and the hook body 12. The size of the lifting hook plate 22 matches the inner diameter of the hook body 12, so that the lifting hook plate 22 can fit with the inner side of the hook body 12 when it descends, so that the hook body 12 can stably support the lifting hook plate 22. The lifting plate 2 is weighted by the yielding perforation 23, and the fixed cross plate 13 guides and limits the lifting plate 2 by the yielding perforation 23 to prevent the lifting plate 2 from detaching from the inner groove 111 and preventing the lifting plate 2 from tilting and deflecting. One end of the lowering hook plate 22 is kept highly flush with the open end of the hook body 12, which is convenient for connection with the cargo. When the rope on the cargo is hung on the lifting hook plate 22, as the lifting crane pulls the traction body 11 upward, the traction body 11 can drive the hook body 12 to pull upward, and the weight of the cargo is applied to the lifting hook plate 22 to press the lifting hook plate 22 downward. The lifting hook plate 22 drives the lifting plate 2 to slide downward through the connecting plate 21, so that the lifting plate 2 can contact the top end of the opening of the hook body 12, forming a closed loop to limit the traction rope on the cargo to prevent unhooking. In this case, the lifting hook plate 22 is always subjected to the weight of the cargo, so that the device can be stably connected to the cargo rope, and the lifting plate 2 drives the limiting wedge 3 to descend. When the limiting wedge 3 reaches the position of the side groove 112, the spring piece 31 pushes the limiting wedge 3 to insert into the side groove 112, so that the hook 1 can limit the lifting plate 2 through the side groove 112 and the limiting wedge 3, and realize automatic locking. There is no need for manual locking by the staff, which strengthens the stability of the closed-loop limiting of the cargo rope, is relatively simple to operate, saves time and effort, and improves the connection and installation efficiency and the flexibility of use.

[0018] Two guide slide bars 14 are fixedly connected to the top of the fixed cross plate 13, and the two guide slide bars 14 are fixedly connected to the inner wall of the inner groove 111. The guide slide bar 14 passes through the top of the lifting plate 2, and the lifting plate 2 is slidably connected to the side walls of the two guide slide bars 14. The return spring 24 is sleeved on the corresponding side walls of the guide slide bars 14; the guide slide bar 14 cooperates with the fixed cross plate 13 to slide and limit the lifting plate 2, so that the lifting plate 2 can remain stable when sliding up and down, and the guide slide bar 14 provides internal support for the return spring 24 to prevent the return spring 24 from excessive bending and affecting its own elastic force.

[0019] The inner wall of the yielding perforation 23 is fixedly connected to the limiting block 25, and the limiting block 25 contacts the top of the fixed cross plate 13; when the lifting plate 2 slides downward, the lifting plate 2 drives the limiting block 25 to slide downward, and when the lifting hook plate 22 drops to the lowest part, the limiting block 25 contacts the top of the fixed cross plate 13, so that the fixed cross plate 13 can limit the lifting plate 2 through the limiting block 25, preventing the lifting plate 2 from continuing to slide downward and causing extrusion damage to the two return springs 24.

[0020] Two arc-shaped limit plates 122 are fixedly connected to the inner side of the hook body 12, and the lifting hook plate 22 is slidably connected between the two arc-shaped limit plates 122; a recessed area is formed between the two arc-shaped limit plates 122, and the lifting hook plate 22 can enter the space between the two arc-shaped limit plates 122 when it descends, and the top opening of the lifting hook plate 22 is consistent with the top opening of the arc-shaped limit plate 122, so that the arc-shaped limit plate 122 can support and pull the rope on the cargo together with the lifting hook plate 22, and the two arc-shaped limit plates 122 limit the lifting hook plate 22 to prevent the lifting hook plate 22 from swinging.

[0021] The inner wall of the side groove 112 is slidably connected with an I-shaped plate 15, and the I-shaped plate 15 is in contact with one end of the limiting wedge block 3; the side groove 112 limits the I-shaped plate 15, and when the limiting wedge block 3 is engaged into the side groove 112, the limiting wedge block 3 pushes the I-shaped plate 15, so that the I-shaped plate 15 can slide toward the outside of the traction body 11, and when the goods are transported to the designated location for unloading, by pressing the I-shaped plate 15, the I-shaped plate 15 pushes the limiting wedge block 3, so that the limiting wedge block 3 can be disengaged from the side groove 112, and then under the push of the two return springs 24, the closed-loop lock of the device can be opened, which is convenient for disassembly and connection with the goods.

[0022] The working principle and use process of the utility model are as follows: when lifting the cargo, the rope or connecting piece on the cargo is put into the gap between the traction body 11 and the hook body 12, and then the cargo rope reaches the top of the lifting hook plate 22. At this time, the lifting plate 2 shrinks inside the inner groove 111. As the lifting crane pulls the traction body 11 upward, the traction body 11 can drive the hook body 12 to pull upward. The weight of the cargo is applied to the lifting hook plate 22 to press the lifting hook plate 22 downward. The lifting hook plate 22 drives the lifting plate 2 to slide downward through the connecting plate 21. The lifting hook plate 22 drops to the position between the two arc-shaped limit plates 122 to limit the position. The lifting plate 2 contacts the top of the hook body 12 to form a closed loop to limit the traction rope on the cargo to prevent the hook from being unhooked. At the same time, the lifting When the lifting plate 2 is lowered, the limiting wedge 3 is driven down. When the limiting wedge 3 reaches the position of the side groove 112, the spring piece 31 pushes the limiting wedge 3 to be inserted into the side groove 112, so that the hook 1 can limit the lifting plate 2 through the side groove 112 and the limiting wedge 3, and realize automatic locking. There is no need for manual locking by the staff, and the stability of the closed-loop limit of the cargo rope is strengthened. The operation is relatively simple, time-saving and labor-saving, and the connection and installation efficiency and the flexibility of use are improved. When the cargo is transported to the designated location for unloading, the I-type plate 15 is pressed, and the I-type plate 15 pushes the limiting wedge 3, so that the limiting wedge 3 can be disengaged from the side groove 112, and then under the push of the two return springs 24, the closed-loop lock of the device can be opened, which is convenient for disassembly and connection with the cargo.
