Climbing device of hydraulic climbing formwork system and control method

Abstract

A climbing device of a hydraulic climbing formwork system is provided with a lifting device, a track, a step device, a hydraulic pump station and a bearing frame. Fixed fork lugs are fixed to the cylinder ends of climbing jacks, the ends of pistons are connected with movable fork lugs through movable connection structures, the fixed fork lugs and the movable fork lugs are reliably connected with upper climbing boxes and lower climbing boxes through shaft pins; displacement sensors are fixed to the cylinders of the climbing jacks; inlet openings and return openings of the climbing jacks are installed on nozzle blocks and are in the same direction with the axial direction of the cylinders, wherein the return openings are higher than the inlet openings, and the return openings are connected to return cavities in the climbing jacks; and a main control center performs controlling through setting the climbing parameter setting step, the jack cylinder synchronization control strategy and the safety protection strategy. The climbing device of the hydraulic climbing formwork system has the advantages that a set of pumping stations controls multiple climbing points simultaneously, the bearing capacity is great, climbing of multiple formworks can be realized simultaneously, the synchronous control precision is high, fewer operators are needed, and safety and reliability are realized.

Description

technical field [0001] The invention relates to a construction device for high-rise buildings such as bridge main towers, bridge piers, columns, and water conservancy dams, in particular to a climbing device and a control method for a hydraulic climbing formwork system. Background technique [0002] At present, in the construction of high-rise buildings such as bridge towers and bridge piers, most of the formwork systems used are overturned forms. The overturned slab system is a three-layer structure. The upper formwork is supported by the lower formwork. Disassemble and reassemble at the top. This formwork system has poor versatility, low efficiency, and great potential safety hazards. In order to solve the above problems, some automatic climbing formwork devices have appeared in China. Through a number of suspension devices arranged on the poured concrete, a track that can be hoisted on the suspension device, a stepping device for climbing and a load-bearing frame, etc., ...

AI Technical Summary

Problems solved by technology

However, the current hydraulic climbing formwork system still has shortcomings: the synchronization control accuracy between multiple climbing points is low, it is difficult to realize simultaneous lifting of multiple formworks, and usually only one set of formworks can be climbed at a time, which affects the construction efficiency
