Description

Technical Field

[0001] The utility model relates to the technical field of shaft construction, in particular to a hydraulic synchronous lifting system for a vertical tunneling shield. Background Art

[0002] A shaft is a vertically walled well-shaped pipeline, which is actually a collapse funnel. It is square, long strip or irregular circular in plane contour. The shaft wall is steep and almost vertical. Shafts are widely used in water intake, water diversion, ventilation, slag chutes, and air supply in water conservancy and hydropower projects. Shaft construction has the characteristics of small floor area and less interference to surrounding construction. However, the construction space of shafts is small, the construction period is long, there are many high-altitude and edge operations, and the traffic is inconvenient, resulting in prominent safety risks in shaft construction. Shafts can be classified according to their diameter, cross-sectional shape and depth, etc.

[0003] In order to reduce the sinking resistance, the lower end of the shaft wall is usually made into a blade shape, and this blade-shaped structure is called a "cutting edge". In the new shaft construction technology, in order to ensure the controllability of shaft sinking, steel strands are usually used to connect the cutting edge of the shaft to a large-tonnage piston cylinder placed on the ground, and then the piston cylinder drives the steel strands to move to achieve the purpose of controllable shaft sinking. In the whole process, the steel strands need to bear the weight of the shaft, so improving the reliability of the steel strand action is a key requirement in shaft operation.

[0004] Therefore, a hydraulic synchronous lifting system for a vertical tunneling shield that can solve the above problems is needed. Summary of the Invention

[0005] The purpose of the utility model is to provide a hydraulic synchronous lifting system for a vertical tunneling shield according to the deficiencies of the above-mentioned prior art. The system is composed of steel strands, a steel strand pay-off reel, a steel strand guide frame, a through-core hydraulic cylinder and an anchor plate. One end of the steel strand is wound on the steel strand pay-off reel, and the other end of the steel strand passes through the steel strand guide frame, the through-core hydraulic cylinder, the first steel strand channel of the top reinforcement structure and the second steel strand channel of the cutting edge of the shaft in sequence and is anchored on the anchor plate. The through-core hydraulic cylinder drives the steel strand to move, so as to realize the sinking of the shaft.
