Abstract

The invention discloses a measuring device of a shield tail gap of a shield tunneling machine and a measuring method thereof, and belongs to the field of tunnel engineering technology. The measuring device comprises a housing body, a motor, a hydraulic oil cylinder, an encoder, a rotor plate, a measuring rod, a position sensor and a controller. The motor and an oil cylinder seat of the hydraulic oil cylinder are arranged in the housing body. The oil cylinder seat of the hydraulic oil cylinder is connected with an output shaft of the motor. The axis of a position rod of the hydraulic oil cylinder and the axis of an output shaft of the motor are on the same straight line. The encoder is installed on the side wall of the oil cylinder seat. The piston rod of the hydraulic oil cylinder stretches out of the housing body and is installed on one side end face of the rotor plate. One end of the measuring rod is installed on the other side end face of the rotor plate. The position sensor is installed on the measuring rod. The encoder and the position sensor are connected with the controller. The measuring device is simple to operate, precise in measuring results and quite high in safety. Meanwhile, efficiency and automation degree of measurement of the shield tail gap of the shield tunneling machine are improved.

Description

technical field [0001] The invention relates to the technical field of tunnel engineering, in particular to a measuring device and a measuring method for a shield tail clearance of a shield machine. Background technique [0002] The shield machine is a special construction machine for tunnel excavation. During shield construction, due to the curvature change of the shield machine’s propulsion route and the protruding length of the propulsion cylinder cannot be kept consistent at all times, the inside of the shield machine and the segment The space between the outer sides changes, and this changed space is the shield-tail gap. When the variation of the shield tail gap exceeds the allowable range of the design, it will cause excessive extrusion between the shield tail and the segments, thereby accelerating the wear of the segment and shield tail seal brushes, thereby destroying the shield tail sealing system , It may even cause major construction problems such as the deviatio...
