Embodiment Construction

[0015] like figure 1 As shown, a method for quick leveling of the tripod bracket of the surveying instrument is to install an airbag support device on the tripod bracket of the surveying instrument; The structure is that the three mouth pipes of the four-way pipe 10 are respectively connected to the gate valve 9, and each gate valve 9 is respectively connected to the ventilation hose 8, and the other nozzle of the four-way pipe 10 is connected to the upper valve 11; the specific leveling steps Yes:

[0016] In the first step, at first drill through holes at the bottom of the three leg sleeves 1 of the tripod, install the above-mentioned three telescoping bags 5 in the inner cavities of the three leg sleeves 1 respectively, and make each The air inlet 6 of the telescoping bag 5 is exposed from the corresponding through holes respectively, and is for standby;

[0017] In the second step, during on-site surveying and mapping work, loosen the fastening screws 3 on the three legs...

Abstract

The invention discloses a rapid leveling method for a surveying instrument tripod. The method is characterized in that the method is characterized by comprising the following steps: firstly, through holes are drilled in lower portions of sleeves of three supporting legs of the tripod, air bags extending in the axial direction and air inlets are formed in inner cavities of the supporting leg sleeves, during field surveying and mapping work, the three air bags are communicated through connecting parts, then a certain amount of air is inflated into the air bags through inflating equipment for inflating valves, and a support platform is in a suspension state; and then a palm is used for pressing the support platform at different acting points, a level bubble is observed at the same time, whenthe level bubble is observed to reach the horizontal state, fastening screws are screwed down to fix three scale sliding rods, all gate valves are closed at the same time, and the tripod is kept in the horizontal stable state.

Description

technical field [0001] The invention relates to a tripod for a surveying instrument. Background technique [0002] At present, the triangular bracket of the surveying instrument used in engineering surveying and mapping of buildings, mines, roads and bridges, etc. consists of a platform component (including bracket platform, connecting bolts, level bubbles, etc.) Fastening screws and pedals, etc.), the three outrigger components are respectively connected to the platform component through the hinge mechanism; the adjustment of the height and horizontal state of the bracket is completed by adjusting the sliding length of the pull rod. This adjustment method takes a long time to adjust and has low precision. Especially in the measurement environment with slopes and uneven ground, it is labor-intensive and time-consuming, and the measurement stability is also affected to a certain extent. Contents of the invention [0003] The purpose of the present invention is to overcome ...
