Double hook automatic hoisting structure and hoisting method

Abstract

The invention relates to a double hook automatic hoisting structure and a hoisting method, and a front and back movement position, a lifting position and a hoisting position of each station are determined by a servo control system at a winding forming station, a cooling setting station and a demolding station in a composite pressure pipe production line so as to conduct precise hoisting. The hoisting structure includes a PLC, a moving crane rack, a left crane and a right crane; the left crane and the right crane are installed at the two ends of the moving crane rack, and the left crane and theright crane move up or down synchronously under the control of the PLC. The hoisting structure has the advantages that firstly, hook lifting guide shafts are used for guiding design to avoid the swing phenomenon of left and right lifting hooks during the lifting process, the synchronous control of lifting positions of the left and right lifting hooks is achieved in hoisting, and the stationarityof a hoisted mould in the lifting is ensured; secondly, hoisting rods are detected by detector switches on the lifting hooks, so that the safety of the hoisting is ensured.

Description

technical field [0001] The invention relates to a system for precise hoisting of the winding forming station, cooling and shaping station, and demoulding station in a composite pressure pipe production line. The invention discloses a double-hook automatic hoisting structure and a hoisting method, which belong to the field of manufacturing special hoisting structures. Background technique [0002] In the existing composite pressure pipe production line, the hoisting mode of the winding forming station, cooling and shaping station, and demoulding station adopts the factory driving hoisting method. Its disadvantages: First, the hook of the factory crane is a steel rope type soft hook, which cannot be automatically hooked during the mold hooking process, and can only be hooked manually; second, the hook of the factory crane is a steel rope type soft hook. During the hoisting operation, the swing is large and the position between each station cannot be precisely controlled; the ...
