Embodiment Construction

[0024] The present invention is further described below in conjunction with embodiment. The examples serve to illustrate the invention, but do not limit the invention in any way.

[0025] The ring-shaped lifting platform for shaft construction is a kind of suspended manned high-altitude operation equipment that is suspended on the top of the cave wall by the I-shaped beam, suspended along the facade of the cave wall with a wire rope, and driven by a motor to run the ring-shaped suspension platform up and down. Well construction operation design. The operating platform has the characteristics of strong construction adaptability, basically unlimited construction height, less construction site occupation, good construction quality, high construction efficiency, convenient erection and disassembly, less labor and low labor intensity, etc., and is ideal for tunnel operations. Preferred device.

[0026] The operating platform of this example is ring-shaped and consists of twelve 3...

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 liftable work platforms in engineering construction, and in particular relates to the design and manufacture of a lift platform for shaft construction. Background technique [0002] So far, in the construction of hydropower shafts at home and abroad, there is no equipment that can meet or meet all-round construction needs. The construction in the shaft section of the hydropower tunnel is relatively difficult. According to the previous construction technology, there are no more than two methods for the consolidation grouting construction of deep and large shaft walls at home and abroad: 1. The construction platform is built with steel frame pipes; 2. The winch drives Hanging cage method. The two methods have their own disadvantages. Among them, when the steel frame pipes are full, the disassembly an...
