Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, the following detailed description is provided in conjunction with the accompanying drawings: a pipe hoisting clamp comprises a left bracket 1, a right bracket 2 and an antiskid device; the left bracket 1 and the right bracket 2 are hinged through a connecting shaft 3; the upper ends of the left bracket 1 and the right bracket 2 are both provided with a fixed rod 5, and the lower ends are both provided with a clamping plate 4; the clamping plate 4 is of an arc-shaped structure.

And the two ends of the fixing rod 5 of the left support 1 and the two ends of the fixing rod 5 of the right support 2 are both provided with a limiting clamping plate 6. In the using process, the opening size of the clamping plate 4 is controlled by the aid of the lifting chain and the lever principle, and the limiting plate 6 is used for limiting the position of the lifting chain so as to ensure that the lifting chain cannot slide when being found in the lifting process, so that dangerous accidents occur.

The upper end of the connecting shaft 3 is provided with a hanging ring 7, and the lower end is provided with a lifting hook 8. When the lifting is unloaded, the connecting shaft 3 is hung through the lifting ring 7, the clamping plate 4 is opened along with the lifting force of the lifting, and the product falls down naturally according to the specified lifting position, thereby saving time, power and labor. The lifting hook 8 is mainly used for hanging the antiskid device.
