Technical Field

The utility model relates to the technical field of building construction, in particular to a movable construction operation platform for removing a chimney.

Background

In the urban reconstruction process, as factories and mines migrate from a city area to a remote area, structures such as original chimneys and the like are not used any more and need to be dismantled, and the chimney is usually dismantled by adopting three modes of manual dismantling, mechanical dismantling and blasting dismantling, wherein the manual dismantling chimney can be divided into integral dumping and sectional dismantling, the integral dumping method has the advantages of short dismantling time, low time consumption and the like, if a wider place is arranged around the chimney, the whole chimney can be arranged, namely, the integral dumping dismantling method can be used for the situation, and if the place is insufficient for supporting the integral dumping dismantling method, the chimney needs to be dismantled by adopting the sectional dismantling mode;

when the chimney is dismantled in a sectional dismantling mode, a corresponding construction operation platform is required to be built, a corresponding protective fence is installed on the construction operation platform, wherein the middle part and the top of the railing are surrounded into a circle by a 018 palm rope perforation (phi 22 nut hole), and after a section of the chimney is dismantled, the operation platform is moved downwards, and the dismantling work of the whole chimney can be completed by secondary pushing; the existing dismantling device is complex in structure, inconvenient to operate and unsafe, and cannot meet the requirements of operators; in order to make up the defects of the prior art, chinese patent CN214462427U provides a movable working platform for removing a chimney, which comprises a single-piece hoop and a derrick mast, wherein the single-piece hoop is arranged on the outer wall of the chimney in an arc shape, the derrick mast is arranged on the single-piece hoop through a hook, and a plurality of hanging holes are equidistantly arranged on the outer wall of the single-piece hoop for hanging the derrick mast; the gin pole comprises a flat plate, a tripod arranged below the flat plate and a guardrail arranged in the groove;
