Embodiment Construction

[0013] The present invention will be described in further detail below by means of specific embodiments:

[0014] The reference signs in the drawings of the description include: supporting plate 1 , working plane 2 , front shield 3 , double-acting hydraulic cylinder 4 , back shield 5 , and hinge 41 .

[0015] The embodiment is basically as attached figure 1 , figure 2 Shown: Shield propulsion and articulation system, including 10 double-acting hydraulic cylinders 4, 10 single-acting hydraulic cylinders, the maximum stroke of the single-acting hydraulic cylinders is 2150mm;

[0016] The double-acting hydraulic cylinder 4 and the single-acting hydraulic cylinder are evenly distributed in the middle shield and are distributed parallel to each other in concentric circles. The double-acting hydraulic cylinder 4 is located on the outside, and the single-acting hydraulic cylinder is located on the inside. The middle shield is embedded and fixed There are 10 stepped holes for fixin...

Abstract

The invention discloses a shield advancing and hinging system, comprising a plurality of double-acting hydraulic cylinders, a plurality of single-acting hydraulic cylinders. The double-acting hydraulic cylinders and the single-acting hydraulic cylinders are evenly distributed in a middle shield and are mutually parallel, wherein a carrier plate is fixed to a push rod head at each of same ends of the double-acting hydraulic cylinders and single-acting hydraulic cylinders are. The carrier plates may form a complete work plane. Push rods at the other ends of the double-acting hydraulic cylinders are hinged to a rear shield. Cylinder blocks of the single-acting hydraulic cylinders are fixed to the middle shield. By using the system, adjusting efficiency of a shield tunneling machine is greatly improved.

Description

technical field [0001] The invention relates to the field of shield machines, in particular to the key part of the shield machine—the propulsion and articulation system. Background technique [0002] Shield machines are mainly used in tunnel construction. With the diversification of market demand, miniature shield machines (diameter ≤ 3m) have become one of the development trends in the shield machine industry, especially for various shallow pipelines in the city. The ultra-small-diameter circular shield machine with the diameter of the laid shield surface ≤ 1m is widely used in the fields of municipal water supply and drainage pipelines and cable laying. [0003] In order to facilitate the construction of tunnels with curves, the shield machine is equipped with an articulation system. Affected by geological conditions, soil pressure distribution on the excavation surface, engineering design, segment attitude, grouting pressure, rotation angle and other factors, there is a ...
