Abstract

The tripod is placed to adjust the reference device, which is installed on the tripod and includes a casing with a stepped structure. A laser plummet is installed in the lower end of the casing. The laser plummet includes a laser diode, and the laser diode is connected to the power supply battery, respectively. The control button for controlling its switch is connected; a circular level is installed in the upper end of the shell, and the circular level is connected with the laser plummet. Beneficial effects of the present invention: (1) The device integrating the laser plummet and the circular level is applied to the theodolite tripod, which makes the centering and leveling process of the theodolite convenient and quick, and improves the efficiency of surveying and mapping. (2) The present invention uses plastic as the shell material, which is shock-proof and drop-proof. The whole device has simple structure, low cost, easy implementation and portability. It can not only increase the placement speed of the theodolite, but also improve the placement accuracy of the theodolite, and has broad prospects for popularization and application.

Description

technical field [0001] The invention relates to a theodolite tripod accessory, in particular to a tripod placement adjustment reference device for realizing centering and leveling of the theodolite tripod. Background technique [0002] The placement of theodolite mainly includes two parts: centering and leveling. It is an important and primary link for accurate observation of theodolite. The accuracy and efficiency of its placement will directly affect the accuracy of observation. In the observation of theodolite with complex terrain conditions such as soft or mountainous terrain, the placement of theodolite needs to be erected and fixed at the position of three tripods first, complete the preliminary centering and leveling, and then complete the precise alignment by moving the theodolite and leveling the foot bolts Leveling. The specific operation steps are: (1) Preliminary centering and leveling. Fix the tripod, and visually judge that the center of the tripod support is...
