Description

Technical Field

[0001] The utility model relates to the technical field of lifting hooks, in particular to a lifting clamp for plate feeding. Background Art

[0002] Lifting clamps are a kind of tool specially used for lifting and carrying large metal components such as metal plates and steel pipes in industry. It is different from traditional lifting hooks. Lifting clamps are mainly used to directly clamp metal materials for lifting without lifting rings or hook beams.

[0003] Reference patent document publication number CN218841449U is a lifting clamp for plate loading, including a U-shaped plate, a butt plate is provided on the upper left side of the U-shaped plate, the butt plate is hingedly connected to the U-shaped plate through a pin rod, a lifting chain is provided on the upper side of the butt plate, and the lower surface of the butt plate is processed with friction grains. The lifting clamp for plate loading, through the cooperation between the U-shaped plate, the bottom plate, the pin rod, the lifting chain, the friction grains, the rubber pad and the stabilization component, can make the circular plate and the rubber cylinder move to the right together due to the threaded connection relationship between the screw rod and the horizontal cylinder, so that a negative pressure state can be formed on the left side of the horizontal cylinder, the short tube and the micropores, so that the left surface of the rubber sticker can be partially adsorbed and pressed against the plate to be hoisted and moved, and then the stability between the U-shaped plate and the plate to be hoisted and moved can be greatly improved. The center of gravity of the plate is not easy to shift during the subsequent hoisting process, which is conducive to the stable lifting of the plate.

[0004] Although the above scheme can lift metal plates when used, there are still some shortcomings during use. For example, it is difficult to position the device on the metal plate during use, which makes it easy for the device to slide on the metal plate during lifting, resulting in the risk of the plate falling off during lifting. Therefore, a lifting clamp for plate loading is proposed to solve the above problems. Utility Model Content
