Problems solved by technology

Multiple measuring components need to be placed in multiple positions of the shield machine. Since the entire measuring device is relatively scattered, it increases the difficulty of installation and the cost of maintenance. The use of optical components is easily affected by the visibility conditions, and there are many inconveniences in use.

Abstract

The invention discloses a shield tunneling machine pitch angle and roll angle measuring device. The shield tunneling machine pitch angle and roll angle measuring device comprises a mounting plate, anupper end of the mounting plate is fixedly connected with an electric telescopic rod, an upper end of the electric telescopic rod is fixedly connected with a shell, one end of the shell is provided with an opening, a hydraulic cylinder is fixedly connected with the inner wall of the shell, a fixed plate is fixedly connected with a telescopic end of the hydraulic cylinder, two sector disks are fixedly connected with one end, away from the hydraulic cylinder, of the fixed plate. The pitch angle and roll angle measuring device proposed by the invention can determine the pitch angle and the roll angle of the shield tunneling machine by observing a position of a display screen pointed by a laser tip at any time during a tunneling process of the shield tunneling machine, so even if an automaticguiding system of the shield tunneling machine fails during the tunneling process, and the measuring device is used to manually measure the pitch angle and the roll angle of the shield tunneling machine, the normal tunneling of the shield tunneling machine can be ensured and the reliability of the shield tunneling machine is greatly improved.

Description

technical field [0001] The invention relates to the technical field of shield machines, in particular to a device for measuring pitch angles and roll angles of shield machines. Background technique [0002] During the tunneling process of the shield machine, the measurement of the pitch angle and roll angle of the shield attitude is completed by the automatic guidance system. Manual measurement is carried out before the start of the shield machine, and then the pitch angle and roll angle of the shield machine are determined by setting the parameters of the automatic guidance system. However, once the automatic guidance system of the shield machine is abnormal during the tunneling process, or there is a problem with the hardware of the equipment for measuring the pitch and roll angles, there will be no way to determine the attitude of the shield machine, which will have a great impact on the construction. [0003] The patent with the publication number CN101251367A discloses...
