[0040] The power assembly 130 is connected to the outside of the hook connection portion 1122 and is configured to drive the cutter 121 to move along a first direction to a position abutting the inner edge of the hook body 1121 to cut off the sling 1401, wherein the first direction is the falling direction of the sling 1401.

[0041] Figure 1 Schematic diagram of the structure and working principle of the hook provided in an embodiment of the present application.

[0042] like Figure 1 As shown, the hook 100 in this embodiment includes a hoisting unit 110, a cutting assembly 120, and a power assembly 130. The hoisting unit 110 includes a lifting ring unit 111 and a hook unit 112. The lifting ring unit 111 includes a lifting ring body 1111 and a lifting ring connecting portion 1112. The lifting ring connecting portion 1112 extends along a first direction, and the lifting ring body 1111 and the lifting ring connecting portion 1112 are sequentially connected along the first direction. Specifically, the lifting ring body 1111 is connected to a first end of the lifting ring connecting portion 1112, and a second end of the lifting ring connecting portion 1112 is connected to the hook unit 112. The lifting ring body 1111 is an annular member. The external hanging device cooperates with the lifting ring body 1111 to complete the lifting operation of the hook 100.

[0043] The hook unit 112 includes a hook body 1121 and a hook connection portion 1122. The hook connection portion 1122 and the hook body 1121 are sequentially connected along a first direction. The hook connection portion 1122 extends along the first direction. The first end of the hook connection portion 1122 is rotatably connected to the second end of the ring connection portion 1112.

When the object to be transported 1402 is lifted by the hook 100, the rotational connection between the hook connecting part 1122 and the ring connecting part 1112 can rotate the hook unit 112 relative to the axis of the ring unit 111. After lifting, the object to be transported 1402 will shake when suspended in the air. The rotational connection between the ring unit 111 and the hook unit 112 can make the connection between the ring unit 111 and the hook unit 112 more stable.

[0044] The cutting assembly 120 includes a cutter 121, which is connected to the hook unit 112. The shape of the blade 1211 of the cutter 121 matches the shape of the hanging surface 1126 of the hook arm 1125. The power assembly 130 is connected to the outside of the hook connection portion 1122 and is capable of driving the cutter 121 to move along a first direction until the cutter 121 and the inner edge of the hook body 1121 abut each other, thereby cutting the hanger 1401. It should be noted that the first direction is the direction in which the hanger 1401 is falling. By arranging the cutting assembly 120 and the power assembly 130 on the hook unit 112, and completing the cutting operation of the hanger 1401 through the interaction between these components, the traditional manual cutting operation of the hanger is eliminated, thereby effectively improving the efficiency of the electroplating operation.

[0045] As a possible embodiment, along the first direction, a first accommodating chamber 1123 is provided on the side of the hook connecting portion 1122 facing away from the lifting ring unit 111, and the first accommodating chamber 1123 has an opening, and at least part of the structure of the power component 130 is provided in the first accommodating chamber 1123 through the opening.

A portion of the power assembly 130 is disposed within the first accommodating chamber 1123 through the opening, and a portion of the power assembly 130 is connected to the outside of the hook connection portion 1122. Power assemblies located at different locations on the hook connection portion 1122 are interconnected. The portion of the power assembly 130 located within the first accommodating chamber 1123 is connected to the cutter 121 to drive the cutter 121 to move along the first direction.

[0047] Possibly, the cutter 121 includes a flat-plate-shaped mounting portion 1212, the blade 1211 of the cutter 121 is connected to the end of the mounting portion 1212, and the blade 1211 faces the hanging surface 1126 of the hook arm 1125; the hanging surface 1126 of the hook arm 1125 has a groove, the position of the groove matches the blade 1211 of the cutter 121, and when the cutter 121 cuts the hanger 1401 along the first direction, the blade 1211 moves into the groove.

[0048] Specifically, refer to Figure 1The cutter 121 is a flat piece, and the cutter 121 has a mounting portion 1212, the mounting portion 1212 extends along the first direction, the first end of the cutter 121 is connected to the power assembly 130 in the first accommodating cavity 1123, the second end of the cutter 121 is a blade 1211, the blade 1211 faces the hook arm 1125, and the hook arm 1125 has a hanging surface 1126 along the first direction, and the hanging surface 1126 is the hanger 1401 on the hook arm 1125 and the hook body 1 121 contacts the surface, the blade 1211 of the cutter 121 faces the hanging surface 1126, the hanging surface 1126 has a groove (not shown in the figure), along the first direction, the groove is recessed toward the inner side of the hook arm 1125, and the groove and the blade 1211 of the cutter 121 match. When the power component 130 in the first accommodating cavity 1123 drives the cutter 121 to move along the first direction to the hanging surface 1126 and enter the groove, the hanger 1401 is cut off at the hanging surface 1126.

[0049] As a possible implementation, the hook body 1121 in this embodiment is a symmetrical structure symmetrically arranged along a vertical plane. At this time, the cutter 121 is located on the symmetrical plane of the hook body 1121, and the cutter 121 extends along the symmetrical plane, and the groove also extends along the symmetrical plane.

[0050] Optionally, the cutting assembly 120 further includes a guide rail 122, which extends along a first direction and is connected to a side of the hook body 1121 facing away from the opening 1124. Accordingly, a groove is recessed on the hook arm 1125 of the hook body 1121 toward the hook body 1121, and the guide rail 122 is connected to the groove in a horizontal direction. Along the first direction, both ends of the guide rail 122 are respectively connected to the hook body 1121. Furthermore, the cutter 121 is connected to the guide rail 122. Specifically, the guide rail 122 includes a first guide groove (not shown in the figure), which extends along the first direction and is located on a side of the guide rail 122 facing away from the hook body 1121. The cutter 121 includes a second guide groove (not shown in the figure), which extends correspondingly along the first direction and is located on a side of the cutter 121 closer to the guide rail 122. The second guide groove is movably connected to the first guide groove. When the power assembly 130 drives the cutter 121 to move, the second guide groove of the cutter 121 moves along the extension direction of the first guide groove of the guide rail 122. The cooperation between the first guide groove and the second guide groove ensures that the movement of the cutter 121 in the first direction remains stable, effectively limiting the direction of movement of the cutter, thereby accurately cutting the spreader.

[0051] Possibly, one end of the lifting ring connecting portion 1112 is open and has a second accommodating cavity 1113 , the hook unit 112 and the end opposite to the opening of the lifting ring connecting portion 1112 are rotatably connected, and the hook connecting portion 1122 extends into the second accommodating cavity 1113 .

[0052] During the lifting process, the object to be transported 1402 will swing along its own gravity. In order to stabilize the connection between the eye unit 111 and the hook unit 112 of the hook 100, the second end of the eye connection portion 1112 is provided with an opening, which faces the hook unit 112 and has a second accommodating chamber 1113. The hook connection portion 1122 extends along the first direction into the second accommodating chamber 1113. A bearing 1114 is also provided in the second accommodating chamber 1113. The inner ring of the bearing 1114 is connected to the outer wall of the hook connection portion 1122, and the outer ring of the bearing 1114 abuts against the wall of the second accommodating chamber 1113, thereby allowing the hook unit 112 to rotate relative to the eye connection portion 1112 at the opening of the eye connection portion 1112.

[0053] Possibly, the power assembly 130 includes a hydraulic unit 131, a control unit 132 and a battery pack 133, the hydraulic unit 131 includes a hydraulic pump 1312 and a hydraulic cylinder 1311, the hydraulic pump 1312 and the hydraulic cylinder 1311 are connected, the hydraulic cylinder 1311 is connected to the hook connection part 1122 and the cutter 121, so as to drive the cutter 121 to move relative to the hook connection part 1122 under the power drive of the hydraulic pump 1312; the hydraulic pump 1312 and the battery pack 133 are both electrically connected to the control unit 132, and the control unit 132 is used to control the hydraulic pump 1312 to generate power.

[0054] Optionally, the control unit 132 includes a wireless communication module 1321 and a controller 1322 , and the wireless communication module 1321 and the controller 1322 are electrically connected.
