Technical Field

The utility model relates to the technical field of hoisting clamp equipment, in particular to a precast slab hoisting clamp.

Background

Prefabricated panels are floors used in early construction, i.e. modules or panels for construction. Because the prefabricated concrete member is produced and formed in the prefabricated field and is directly transported to a construction site for installation, the prefabricated plate is called. Prefabricated panels are used in many applications in construction, such as cement panels covered by ditches beside roads, and cement panels with insulation on roofs are prefabricated panels.

The prefabricated plate has two purposes of solid and hollow, and the hollow prefabricated plate is made simply because the hollow position of the plate is not stressed, so that the unstressed place can be emptied, thereby achieving the purposes of reducing the weight and saving the manufacturing cost.

The hoist is often needed to hoist the precast slab in the use process of the precast slab, but the existing hoisting clamp for the precast slab bites the slab through the jaw of the hoisting clamp, and then the hoist is used for pulling the hoisting ring of the hoisting clamp to hoist the slab. The working principle of the hoisting clamp is that the self weight of the hoisted plate is converted into pressure by utilizing the lever principle to act on the jaw, the pressure is interacted with the hoisted plate to generate friction force to work, and the friction force is increased by increasing the friction coefficient of the clamp teeth. However, when the hollow precast slab is hoisted, when the jaw of the hoisting clamp bites the precast slab, the precast slab is easy to deform, and the normal use of the precast slab is further affected.
