Description

A centering and leveling device for measurement training

technical field

The utility model relates to the field of measurement, in particular to a centering and leveling device for measurement training.

Background technique

In the construction survey of power transmission and distribution lines, the most widely used measuring instruments are optical theodolites (total stations, etc.), which are precision optical instruments and are relatively expensive. However, line construction measurement is a profession that must be involved in new employees in the industry, students from junior colleges and technical colleges with similar majors, student internships in power system transmission and distribution professionals with certificates, and skill level promotion exams. Measurement training equipment is inseparable from the middle school. The centering and leveling exercises in the measurement training are the basis of all measurement practical projects. Without the centering and leveling of measuring instruments, there is no real line construction measurement. The purpose of leveling the measuring instrument is to make the vertical axis of the instrument in a vertical position by adjusting the air bubble of the level tube of the measuring instrument. The purpose of measuring instrument alignment is to place the instrument so that its center and station mark are on the same plumb line. In the actual measurement work, the centering of the vertical ball on the tripod or the optical plummet can be used to place the measuring instrument. All measuring instruments are centered and leveled to make the collected data more accurate. If it is not leveled, the measured vertical and horizontal angles will be inaccurate. If it is not centered, the measured distance and angle will not be calculated from the point of placement. The higher the accuracy of centering and leveling, the higher the guarantee of measurement data accuracy.

During the daily measurement training, trainees repeatedly disassembled and assembled the optical theodolite (total station) and tripod in order to practice measuring the accuracy of centering and leveling. Often during training, improper use or carelessness can easily cause damage to precision optical instruments, and the cost of maintenance is not low. Even for skilled surveyors, when using an optical theodolite (total station) for centering and leveling in the field with complex terrain or under severe weather conditions for a long time, it is easy to neglect or accidentally cause damage to the instrument, which increases the maintenance of the instrument Maintenance costs, reduced instrument uptime cycle,.
