When the inclination angle measuring device is arranged on the side surface of the upright post, the dial is inclined along with the upright post, and the numerical value indicated by the pointer on the dial is the inclination angle of the upright post.
The device can well measure the inclination angle of the upright post, but the device can only monitor the inclination angle of the upright post in the front-back direction and cannot measure the inclination angle of the upright post in the side direction; in addition, the device is complex to install and can not be reused after installation, so that resource waste is caused, and the device needs to be repeatedly installed when measuring the inclination angles of a plurality of stand columns, is time-consuming and labor-consuming, and is not suitable for narrow working environment in a coal mine; meanwhile, the device is arranged on the side surface of the hydraulic support and is limited by the diameter of the upright post of the hydraulic support, so that a large dial cannot be arranged, and the inclination angle measurement is not accurate and is not easy to read.
