Description

Special lifting hook for self-made steel mould

Technical Field

The utility model relates to a pole production facility field especially relates to a special lifting hook of self-control steel mould.

Background

The pole is the bridge of electricity, lets the electricity transport each place, and we common pole have wooden system pole, has the cement pole, and their height differs, stands upright in the plain mountain, spreads all over around people. The general category of poles is many, and concrete poles are commonly made of concrete and steel bars or wires. The iron pole is cast by pig iron, and the concrete pole has two types of prestress and non-prestress. The section of the electric rod is square, octagonal, I-shaped, annular or other special-shaped sections. Circular cross-sections and square cross-sections are most commonly used. The length of the electric pole is generally 4.5-15 meters.

The electric pole manufacturing process mainly comprises the steps of longitudinally tensioning the steel wire framework in the steel mould, and then extruding out excessive moisture from the concrete under the action of centrifugal force, so that the compactness and strength of the concrete are greatly improved. However, the problems of low operation efficiency exist in hoisting the mould, opening the mould and turning over the mould in the process of producing the electric pole in mountains by using the steel wire rope, and meanwhile, potential safety hazards exist in the hoisting process of the steel wire rope due to abrasion of the steel wire rope.

The utility model provides a special lifting hook of self-control steel mould solves above-mentioned problem.
