Embodiment 1

[0034] Embodiment 1: a kind of coil hook, such as Figure 1 to Figure 4 As shown, it includes the hook arm 11, the hook back 12 and the hook head 13 which are fixedly connected in sequence. In this embodiment, the hook arm 11 and the hook back 12 are integrally arranged, and a lifting ear 2 is fixed above the hook arm 11 to facilitate Driving and transporting: the hook arm 11 is arranged in a rectangular parallelepiped, and the long side is placed horizontally, the hook back 12 is in a rectangular parallelepiped shape and is connected with 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.

[0035] like figure 2 and Figure 4 As shown, on the hook arm 11, there is a guide groove 16 with a cross-shaped cross section, and the guide groove 16 is arranged along the horizontal direction; in the guide groove 16, a collision plate 3 is slidably connected, and the coll...

Embodiment 2

[0042] Embodiment 2: a kind of coil hook, such as Figure 5 and Figure 6 As shown, the difference from Embodiment 1 is that the setting 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 are omitted. 3. Fix the pressure sensor 71, and fix the hydraulic cylinder 72 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; the hydraulic cylinder 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.

[0043] During use, the worker will hold the hook back 12, move the collision plate 3 towards the aluminum coil, move the hook back 12 along the axial direction of the aluminum coil, the pressure sensor 71 will col...

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 coil lifting equipment, more specifically, it relates to a coil hook. Background technique [0002] At present, domestic and foreign aluminum coils and aluminum plates are hoisted with C-type hooks. The C-type hooks include the hook back and the hook head. The inner elevation of the hook back and the upper surface of the hook head frequently collide or rub against the 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 process, some manufacturers use a FRP protective ring, that is, install a FRP protective ring on the end face of the aluminum coil and the C-hook contact side before lifting. Although this approach has certain effects, the FRP protective ring is easily damaged by long-term impact. [0003] At present, the Chinese patent with the publication number CN203319516U discloses a C-shaped hook and its anti-collision device. I...
