Abstract

The invention discloses a high-efficiency rack mounting method of a gear rack climbing type vertical ship lift. The method comprises the following steps: (1) arranging a rack reference point; (2) mounting a bottom auxiliary device; (3) lifting and primarily reinforcing a rack; (4) welding a wire frame at the top of the rack and arranging a point regulation control measurement tool; (5) returning the rack reference point to the point regulation control measurement tool and hanging a vertical line; (6) adjusting and reinforcing the rack in the elevation direction; (7) laterally adjusting and reinforcing the rack; (8) forwardly adjusting and reinforcing the rack; (9) erecting templates; (10) mounting prestressed reinforcements; (11) checking and accepting the rack before grouting; (12) performing clearance grouting; (13) tensioning after grouting; (14) tensioning the prestressed reinforcements; finally checking and accepting the mounting quality. According to the high-efficiency rack mounting method and the auxiliary adjustment device, the rack can be quickly mounted in a high-quality manner, various construction difficulties are overcome, and the effects of economy, high quality and high efficiency are achieved.

Description

technical field [0001] The invention relates to an efficient installation method and device for a rack, in particular to an efficient installation method and an auxiliary adjustment device suitable for installation projects of ultra-high-precision racks of various types of rack and pinion climbing vertical ship lifts. Background technique [0002] The Three Gorges large-scale rack and pinion vertical ship lift project, as the first scientific research project in the field of ship lifts for hydropower projects at home and abroad, is facing many technical problems. There is no experience that can be used for reference in related fields. It has outstanding construction difficulties such as large single-piece size and weight, complex structure, high installation height, technical difficulty, and high installation quality requirements. It is necessary to innovate and develop suitable installation technologies to overcome various problems. Difficulties, to achieve the smooth const...
