[0004] The utility model adopts the following technical solutions:

[0005] The utility model provides an anti-dropping device for a crane hook, comprising a crane hook, a connecting piece is arranged on the crane hook, a driving assembly is arranged at the right end of the connecting piece, an action end of the driving assembly is connected to the right end of a Z-shaped anti-dropping hook, the anti-dropping hook is rotatably connected to the top end of the crane hook, and the left end of the anti-dropping hook is against the inner wall of the crane hook.

[0006] Furthermore, the driving assembly includes a shell, which is fixedly connected to the right end of the connecting member, and an electric push rod is arranged in the shell. The upper end of the electric push rod is rotatably connected to the shell, and the lower end is rotatably connected to the middle area of ​​the crank. The top end of the crank is rotatably connected to the connecting member, and the bottom end is rotatably connected to the top end of the connecting rod, and the bottom end of the connecting rod is rotatably connected to the right end of the anti-disconnection hook.

[0007] Furthermore, a battery is arranged in the shell.

[0008] Furthermore, a remote control receiver is arranged in the shell.

[0009] Compared with the prior art, the beneficial technical effects of the utility model are:

[0010] The anti-unhooking design of the utility model can be automatically opened and closed by remote control, which is more convenient than the traditional manual opening method. At the same time, when lifting large or high-temperature materials, the operator cannot manually open the shedding device, and automatic opening can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1 As shown, the present embodiment discloses an anti-dropping device for a crane hook, comprising a crane hook 1, a connecting member 2 being provided on the crane hook 1, a driving assembly 3 being provided at the right end of the connecting member 2, an action end of the driving assembly 3 being connected to the right end of a Z-shaped anti-dropping hook 4, the anti-dropping hook 4 being rotatably connected to the top end of the crane hook 1, and the left end of the anti-dropping hook 4 being against the inner wall of the crane hook 1.

[0018] like Figure 2 As shown, in this embodiment, the driving assembly 3 includes a shell 301, which is fixedly connected to the right end of the connecting member 2. An electric push rod 302 is arranged in the shell 301. The upper end of the electric push rod 302 is rotatably connected to the shell 301, and the lower end is rotatably connected to the middle area of ​​the crank 303. The top end of the crank 303 is rotatably connected to the connecting member 2, and the bottom end is rotatably connected to the top end of the connecting rod 304. The bottom end of the connecting rod 304 is rotatably connected to the right end of the rotating rod 4.

[0019] like Figure 3 As shown, in this embodiment, a battery 305 is disposed in the housing 301 , and the battery 305 provides power for the electric push rod 302 .

[0020] In this embodiment, a remote control receiver 306 is disposed in the housing 301 , and the remote control receiver 306 is used in conjunction with a remote controller through electromagnetic coupling of a fixed frequency to control the electric push rod 302 .

[0021] The use process of the utility model is as follows:

[0022] When it is necessary to complete the closing action of the anti-detachment device, the staff controls the electric push rod 302 to extend through the remote control. Under the pushing action of the electric push rod 302, the crank 303 moves clockwise, and the connecting rod 304 moves to the left under the action of the crank 303. Under the pushing action of the connecting rod 304, the anti-detachment hook 4 rotates clockwise, and the left end of the anti-detachment hook 4 rests on the inner wall of the crane hook 1, completing the closing action of the anti-detachment device.

[0023] When it is necessary to complete the opening action of the anti-detachment device, the staff controls the electric push rod 302 to shorten through the remote control. Under the pulling action of the electric push rod 302, the crank 303 moves counterclockwise, and the connecting rod 304 moves to the right under the action of the crank 303. Under the pulling of the connecting rod 304, the anti-detachment hook 4 rotates counterclockwise, and the left end of the anti-detachment hook 4 is separated from the crane hook 1, completing the opening action of the anti-detachment device.
