Embodiment 1

[0033] Example 1: a coil hook, such as Figure 1 to Figure 4 As shown, the hook arm 11, the hook back 12 and the hook head 13 are fixed and connected in sequence. In this embodiment, the hook arm 11 and the hook back 12 are integrally arranged, and a lifting lug 2 is fixed above the hook arm 11, which is convenient for The hook arm 11 is arranged in a rectangular parallelepiped, and the long edge is placed horizontally, the hook back 12 is a rectangular parallelepiped and is connected to one end of the hook arm 11, the long side of the hook back 12 is placed vertically, and the hook head 13 is placed on the hook back The lower end of 12 is connected.

[0034] like figure 2 and Figure 4 As shown, the hook arm 11 is provided with a guide groove 16 with a cross-shaped cross-section, and the guide groove 16 is arranged in the horizontal direction; the guide groove 16 is slidably connected with a resistance plate 3, which is elongated and long The edge is arranged in the verti...

Embodiment 2

[0041] Embodiment 2: a coil hook, such as Figure 5 and Image 6 As shown, the difference from Embodiment 1 is that the arrangement of the first transmission rod 43, the second transmission rod 46, the first sliding seat 42, the second sliding seat 47, and the rotating shaft 44 is omitted. 3. The pressure sensor 71 is fixed on the upper part, and the hydraulic cylinder 72 is fixed on the hook arm 11. The hydraulic cylinder 72 is connected with a control switch 74 that controls the retraction of the piston rod 73 of the hydraulic cylinder 72, and the pressure plate 5 and the piston rod 73 are fixedly connected; 72 is placed on the side of the hook arm 11 facing the bearing plate 132 ; in this embodiment, a single-chip microcomputer is used as the control device 75 .

[0042] When in use, the worker grasps the hook back 12, moves the contact plate 3 toward the aluminum coil, and moves the hook back 12 along the axial direction of the aluminum coil, the pressure sensor 71 collid...

Abstract

The invention discloses a coiled material lifting hook. The problems that in the process of lifting aluminum coils through a C-shaped hook at present, the aluminum coils rotate on a hook head, so that the inner walls of the aluminum coils generate sharp abrasion, and the aluminum coils are damaged are solved. According to the technical scheme, the coiled material lifting hook comprises a hook arm, a hook back and a hook head used for supporting the aluminum coils; the hook arm, the hook back and the hook head are sequentially and fixedly connected, an abutting-contact plate which is in abutting contact with the end faces of the aluminum coils is connected to the hook arm in a sliding manner, and a pressing plate in abutting contact with the outer walls of the aluminum coils is connected to the hook arm in a sliding manner; and the abutting-contact plate is linked with the pressing plate through a transmission assembly, and the aims of avoiding rotation of the inner walls of the aluminum coils on the hook head and avoiding damage to the aluminum coils are achieved.

Description

technical field [0001] The invention relates to the field of coiled material lifting equipment, more particularly, to a coiled material hook. Background technique [0002] At present, most domestic and foreign aluminum coils and aluminum plates are hoisted with C-type hooks. C-type hooks include hook back and hook head. The inner surface of the hook back and the upper surface of the hook head are frequently collided or rubbed with aluminum coil , it is easy to cause damage to the aluminum coil; in order to reduce the damage to the aluminum coil during the lifting and transportation process, some manufacturers use a glass fiber reinforced plastic protective ring, that is, install a glass fiber reinforced plastic protective ring on the end face of the aluminum coil and the C-shaped hook contact side before the lifting and transportation. Although this approach has a certain effect, the FRP protective ring is easily damaged by long-term impact. [0003] At present, the Chinese...
