Problems solved by technology
After the construction workers remove the 8 chain hoists that stabilize the central drum ring, they need to lower the cage from the lower part of the central drum ring to the ground, and the personnel stay directly under the hanging objects for a long time
In addition, the cost of beam fabrication, installation and disassembly is relatively high

Embodiment Construction
[0027] The present invention is further described below.
[0028] The hoisting method for disassembling the central drum ring 1 of the hydraulic mold lifting device disclosed by the present invention includes the following steps:
[0029] Four support beams 7 are symmetrically arranged on the top of the chimney, and the reverse pulley group is arranged on the inner side of each support beam 7, and four poplar winches are respectively arranged corresponding to the support beam 7 and the electrical circuit of the winch is installed;
[0030] Stabilize the central drum circle 1 by using a chain block, and set up a walkway for construction workers to reach the central drum circle 1;
[0031] Lift the steel wire rope of the poplar winder, and fix it at the corresponding lifting point of the central drum ring 1 after going through the reverse pulley group;
[0032] Disassemble the radiation beam and derrick of the form lifting device, and loosen the chain hoist that stabilizes the ...

The invention relates to the field of chimney construction, and discloses a hoisting method for dismounting central drum circles of hydraulic mould lifting devices. The method comprises the followingsteps of symmetrically arranging four support beams at the top of a chimney, arranging a backward pulley block on the inner side of each support beam,respectively arranging four hoisting machines fora corresponding support beam and mounting hoisting machine electric circuits; stabilizing a central drum circle by utilizing a chain block, and building an aisle for the constructors to walk to the central drum circle; lifting the steel wire ropes of the hoisting machines and fixing the steel wire ropes at corresponding hoisting points of the central drum circle after the steel wire ropes pass through the backward pulley blocks; dismounting a radial spar of a mould lifting device and a derrick and loosening the chain block which stabilizes the central drum circle; and carrying out trial hoisting on the central drum circle by utilizing the four hoisting machines, and after the trial hoisting, carrying out synchronous hoisting by the four hoisting machines so as to lower the central drum circle to the ground. According to the method, convenience is brought to the mounting / dismounting construction of a hoisting system, the construction cost is saved, and the mounting / dismounting period ofthe hoisting system is shortened.
Description
technical field [0001] The invention relates to the field of chimney construction, in particular to a hoisting method for disassembling a central drum ring of a hydraulic mold lifting device. Background technique [0002] The hydraulic mold lifting device is an important equipment for chimney construction. Take the YT-16 hydraulic mold lifting device as an example. The YT-16 hydraulic mold lifting device consists of a derrick and a construction platform system, a hydraulic system, an electrical control system, an operating system, and system, hoisting system, small pole hoisting device, etc. The load of the hydraulic lifting system is directly transferred from the load-bearing formwork distributed outside the cylinder to the concrete cylinder wall with a certain strength. The lifting mechanism moves through the oil cylinder fixed on the lifting frame, and relies on the lifting frame and the operating frame to rise alternately along the load-bearing formwork. Elevate tasks. ...
