Measuring instrument foot stool capable of automatically ascending, descending and leveling

Abstract

The invention discloses a measuring instrument foot stool capable of automatically ascending, descending and leveling. The measuring instrument foot stool comprises a work platform (1) and three supporting frames (4) used for supporting the work platform (1), and the supporting frames (4) are connected with the work platform (1) through connection blocks (9). Each supporting frame (4) comprises a screw rod (2), a supporting rod (6), a guide rod (8), a movable block (7) and a direct-current motor (3), wherein three round holes I (7.1) are formed in the movable block (7); the upper end of the screw rod (2) is connected with the corresponding connection block (9), and the lower end of the screw rod (2) penetrates through the round holes I (7.1) to be connected with the direct-current motor (3); the upper end of the guide rod (8) is connected with the corresponding connection block (9), and the lower end of the guide rod (8) is movably connected with the round holes I (7.1); the screw rod (2) is parallel to the guide rod (8). The measuring instrument foot stool can shorten leveling and centering time and improve measurement work efficiency, are easier and more convenient to operate, and can be easily operated by a green hand.

Description

technical field [0001] The invention belongs to the technical field of engineering surveying equipment, and in particular relates to an automatic lifting and automatic leveling measuring instrument tripod. Background technique [0002] The surveying course has strong practicality and wide applicability, and it is a compulsory professional basic course for students majoring in civil engineering. The syllabus requires students to "proficiently master the use of the level and theodolite", that is, students are required to master the operation and use of the level and theodolite. The operation of measuring instruments, especially the operation of theodolite and total station, is difficult for students to master because of the need for centering and leveling. If the operation is carried out according to the methods and steps in various textbooks, the students are always slow to install the instrument. One of the reasons is that: the current measuring instrument tripod is mostly ...

AI Technical Summary

Problems solved by technology

The operation of measuring instruments, especially the operation of theodolite and total station, is difficult for students to master because of the need for centering and leveling

If the operation is carried out according to the methods and steps in various teaching materials, the students always fail to install the instrument. One of the reasons is that the tripods of the current measuring instruments are mostly manually lifted and manually leveled, and the work efficiency is low. Convenience, especially for novice students with insufficient experience, it is difficult to do it well at one time, and it is inconvenient to master its use

In addition, manual operation is often easy to wear some of the parts, so that the life cycle of the tripod is short
