Abstract

The invention discloses a hydraulic system for hinging of a shield tunneling machine. The system comprises a hydraulic oil tank, a hydraulic pump and a hinge oil cylinder. An oil inlet of the hydraulic pump is connected with the hydraulic oil tank, wherein an oil outlet of the hydraulic pump is connected with a port P of a first electromagnetic valve through a pipeline; a port T of the first electromagnetic valve is connected with the hydraulic oil tank through a pipeline; a port A of the first electromagnetic valve is connected with a port A1 of a hydraulic lock through a pipeline; a port B of the first electromagnetic valve is connected with a port B1 of the hydraulic lock through a pipeline; a port A2 of the hydraulic lock is connected with a rodless cavity of the hinge oil cylinder through a pipeline; a port B2 of the hydraulic lock is connected with a rod cavity of the hinge oil cylinder through a pipeline; a floating loop and a backpressure loop are arranged between the hinge oilcylinder and the hydraulic oil tank in parallel and connected through a pipeline; an unloading loop is arranged between the hydraulic lock and the hydraulic oil tank and connected through a pipeline;and a locking loop is arranged between the hydraulic pump and the hydraulic oil tank and connected through a pipeline. The shield tunneling machine hinge hydraulic system is mainly applied to a shield tunneling machine hinge device, and the functions of stretching, retracting, deflecting, following, locking and the like of the hinge device can be achieved.

Description

technical field [0001] The invention relates to the field of shield machines, in particular to a shield machine hinged hydraulic system. Background technique [0002] The shield machine is a special engineering machine used for tunneling in tunnel construction. The shield segment is the main assembly component of the shield construction and the outermost barrier of the tunnel. It is responsible for resisting soil pressure, groundwater pressure and some Due to the effect of special loads, the sensitivity L / D of the shield machine usually reaches about 1.3, and it is difficult to construct in the curved section. In order to facilitate the construction of tunnels with curves and improve the operability of the shield machine, the shield machine is divided into front and rear The two parts, connected in the middle with jacks, form a hinged device. [0003] At present, the articulation system in the prior art is divided into passive articulation system and active articulation sys...
