Lifting platform for shaft construction

Abstract

The invention discloses a lifting platform for shaft construction, comprising an operating platform, a lifter and an electrical control system, wherein the electrical control system controls the lifter to lift the operating platform via a working steel cable, the operating platform is composed of 6 to 12 trapezoid unit joints, at least four groups of anti-collision wall-against wheels are annularly arranged around the operating platform, and the bottom of the operating platform is circumferentially provided with at least four lead screw supporting components. The lifting platform for shaft construction has the advantages of strong construction adaptability, unlimited construction height, small floor area, good construction quality, high construction efficiency, great convenience of erection and disassembly, less labor, low labor intensity and the like. The trapezoid units, which are combined as required by construction, adapt to the construction requirement under different shaft situations, excellent convenience and flexibility are obtained during installation and usage, construction time is saved, and construction cost is lowered; the anti-collision wall-against wheels and the lead screw supporting components can be adjusted to adapt to the different requirements of shaft construction, and the lifting platform can conveniently and safely prevent the operating platform from shaking and becomes more stable and reliable as a whole.

Description

Technical field [0001] The invention belongs to the field of design and manufacture of engineering construction machinery, in particular to the field of design and manufacture of lifting work platforms in engineering construction, and particularly relates to the design and manufacture of a lifting platform for shaft construction. Background technique [0002] So far, in the construction of hydropower shafts at home and abroad, none of the equipment can meet or meet the full range of construction needs. The construction of the shaft section of the hydropower tunnel is more difficult. According to the previous construction technology, there are no more than two methods for the consolidation and grouting of the deep and large shaft walls at home and abroad: 1. Steel frame pipes are filled with construction platforms; 2. Windlass drive Hanging cage method. The two methods have their own disadvantages. Among them, when the steel frame pipe is full, the disassembly and assembly shelf ...
