The main acquisition factor for downhole wireline measurements is the horizontal angle and horizontal distance between points. An important link in the field of underground wire measurement is that the instrument works for centering, leveling, hanging and front-back vision target hammer balls. The purpose of centering and leveling the instrument is to make the vertical axis of the instrument vertical and the horizontal dial horizontal, and to make the instrument center on the plumb line of the measuring station. The target hammer ball is stabilized to be on the same plumb line with the center of the point to be measured, so that the centering errors of the target and the instrument caused by measuring the horizontal angle are reduced, and the wire precision is improved.
Because most underground lead points are arranged on the top plate of the roadway, the instrument needs to be leveled and centered under the points, and generally the instrument is carried out by utilizing a suspended hammer ball. The swinging centering error factor caused by the wind current of the abandoned roadway to the hammer ball hammer line also has the defect that the hammer ball rotates and swings due to the fact that the hammer line is twisted, whether the hammer ball tip and the centering point of the instrument are on the same plumb line cannot be accurately judged, and certain difficulty is caused to the centering of the instrument and the stable field work of the target. The method is time-consuming and labor-consuming, and greatly influences the measurement precision of the lead.
