Problems solved by technology

However, the sliding form construction method has four common quality problems, namely, center drift, cylinder torsion, indentation, and surface cracking of the cylinder. The construction of the derrick requires multiple cable wind ropes, which occupies a large area, high labor intensity, and low efficiency. Disadvantages of high loss; poor synchronization of electric sliding mode lifting, lead screw and nut are fragile and inconvenient to check, poor safety

Abstract

The invention relates to a chimney hydraulic mould lifting device, which comprises a lifting derrick, a platform system, a hydraulic lifting system, a template system, a crane system and an electricalsystem, wherein the lifting derrick and the platform system are arranged on the upper part of a chimney and connected with the hydraulic lifting system; the hydraulic lifting system is arranged on the chimney cylinder body through the template system; the crane system and the electrical system are arranged on the lifting derrick and the platform system respectively; and the electrical system is connected with the hydraulic lifting system and the crane system respectively. The device uses lifting mechanisms evenly distributed around the cylinder wall to gradually lift, and the lifting mechanisms can automatically balance and adjust the pressure through the hydraulic system in the lifting process. The device is suitable for the outer cylinder construction of single-cylinder type reinforcedconcrete chimneys or double-cylinder and multi-cylinder chimneys and can be used in structures, such as silos and the like. The device has the advantages of simple and compact structure, easy layout,lighter weight, convenient processing and manufacture, safe assembling and disassembling process, simpleness, convenience, and smooth operation.

Description

technical field [0001] The invention relates to a lifting device, in particular to a chimney hydraulic mold lifting device. Background technique [0002] At present, the construction equipment for chimneys of thermal power plants mainly include sliding formwork and electric lifting formwork. However, the sliding form construction method has four common quality problems, namely, center drift, cylinder torsion, indentation, and surface cracking of the cylinder. The construction of the derrick requires multiple cable wind ropes, which occupies a large area, high labor intensity, and low efficiency. Disadvantages of large loss; poor synchronization of electric sliding mode lifting, lead screw and nut are fragile and inconvenient to check, and poor safety. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a chimney hydraulic mold lifting device with simple and compact structure,...
