Demolding device for concrete pipe pile

Abstract

The invention relates to a demolding device for a concrete pipe pile. According to the innovation point, the demolding device comprises a first movable hanger and a second movable hanger which are arranged in parallel, wherein the two movable hangers are arranged below beams of traveling cranes and are driven to lift by independent hoisting trolley groups on the beams of the traveling cranes; cover die mechanical claws and bottom die mechanical claws are arranged on the first movable hanger simultaneously; and a plurality of vacuum chucks are distributed on the second movable hanger. According to the demolding device, traveling tracks of the traveling cranes cover the tail end of a die opening chain conveyor and a chain type concrete pipe pile die conveyor and a demolded chain type conveyor on two sides of the die opening chain conveyor. In the integral demolding process, a plurality of actions can be performed simultaneously, so that the work efficiency is improved greatly. In addition, a cover die and a bottom die are grabbed automatically by a manipulator, so manual operation is not required, and the demolding device is safe and reliable, and labor intensity of workers is low; and the concrete pipe pile is attracted by the vacuum chucks, so that friction of the concrete pipe pile is avoided, and the quality of the concrete pipe pile is ensured.

Description

technical field [0001] The invention relates to a demoulding device for concrete pipe piles, in particular to a demoulding device for concrete pipe piles with high working efficiency, safety and reliability. Background technique [0002] With the development of concrete technology, the technology of concrete pipe piles is becoming more and more mature. In addition to being used in industrial and civil buildings, it is also widely used in various fields such as bridges, ports, railways or water conservancy projects. During the production of concrete pipe piles, it needs to go through processes such as feeding, tensioning, centrifugation, room temperature steam curing, stretching, demoulding and high pressure steam curing. [0003] When demolding, the traditional method is to set up a row hanger above the end of the mold opening chain conveyor. A pair of hooks are set on the wire rope of the row hanger, and the hooks are hooked on both ends of the cover mold in a figure-eight ...

AI Technical Summary

Problems solved by technology

Its disadvantage is that when the cover formwork, concrete pipe pile and bottom formwork are removed in sequence, the wire rope hooks of the row crane need to go through the actions of lowering, lifting, translation, lowering and reset, and all the above actions need to be performed by a row crane Realization, the entire demoulding time is very long and the efficiency is very low; at the same time, the steel wire rope is easy to shake when lifting the concrete pipe pile, which causes the scraping of the concrete pipe pile and affects the quality of the concrete pipe pile. Very easy to slip, there is a big safety hazard
