Oil cylinder root angle measuring device and double-shield heading machine attitude measuring system

Abstract

The invention relates to an oil cylinder root angle measuring device and a double-shield heading machine attitude measuring system. The oil cylinder root angle measuring device comprises a first clinometer fixed to a measured oil cylinder and a rotation transmission device fixed to the root of the measured oil cylinder, and a second clinometer is installed on the rotation transmission device. The first clinometer and the second clinometer are both connected with a computer, and the computer obtains the rolling angle and the pitch angle of the detected oil cylinder according to data detected by the first clinometer and obtains the azimuth angle of the detected oil cylinder according to data detected by the second clinometer. According to the invention, the pitch angle, the rolling angle and the azimuth angle of the root of the oil cylinder can be accurately measured in the working process of the measured oil cylinder.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to an oil cylinder root angle measuring device and a double-shield roadheader attitude measuring system. Background technique [0002] Spherical joints are widely used in roadheaders with small turning radius, and have the advantages of flexible rotation and large rotation range. However, when the spherical joint equipment is working, it often has a large range of activities and the installation controls of the measuring equipment are narrow, which seriously affects the performance of the spherical joint. position measurement work. [0003] At present, there is a lack of effective measuring devices, because the equipment installed with spherical joints is usually not allowed to stand by for safety reasons during the work process; due to the large range of motion of spherical joints and flexible activities, it is difficult for conventional measuring equipment to simu...

Problems solved by technology

[0002] Spherical joints are widely used in roadheaders with small turning radius, and have the advantages of flexible rotation and large rotation range. However, when the spherical joint equipment is working, it often has a large range of activities and the installation controls of the measuring equipment are narrow, which seriously affects the performance of the spherical joint. position measurement work

[0003] At present, there is a lack of effective measuring devices, because the equipment installed with spherical joints is usually not allowed to stand by for safety reasons during the work process; due to the large range of motion of spherical joints and flexible activities, it is difficult for conventional measuring equipment to simultaneously measure rolling, The rotation angles in the three dimensions of pitch and azimuth; and the installation space around the spherical joint is usually not large, which also brings great difficulties to the installation and work of the measuring equipment
