Combined surveying and mapping instrument positioning and adjusting device for geological engineering surveying and mapping

Abstract

The invention relates to the technical field of surveying and mapping. The invention provides a combined surveying and mapping instrument positioning and adjusting device for geological engineering surveying and mapping, which comprises a tripod and a surveying and mapping instrument body arranged on the tripod, and the tripod comprises a top platform and three supporting legs which are arranged on the peripheral side of the top platform and hinged to the top platform; the top platform comprises a bottom plate and a top plate, and the top plate is provided with a rotating seat used for installing a surveying and mapping instrument body; a connecting block is arranged on the lower surface of the bottom plate, and the upper ends of the three supporting legs are hinged to the connecting block; a vertical outer threaded pipe is arranged in the center of the lower surface of the connecting block, the upper end of the outer threaded pipe is connected with the connecting block through a first rotating connector, and a first screwing head is arranged at the lower end of the outer threaded pipe. High-precision synchronous opening and closing of the multiple supporting legs can be achieved, use is convenient, and positioning is accurate.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping, in particular to a combined surveying and mapping instrument positioning adjustment device for geological engineering surveying and mapping. Background technique [0002] Surveying and mapping equipment is a kind of equipment that needs to be frequently used in geological engineering design and construction. Commonly used surveying and mapping equipment includes theodolite, level, total station, vernier caliper, screw caliper, etc. In the actual application process, some surveying and mapping equipment such as theodolite and total station need to be used with a tripod to ensure the accuracy of its measurement. At present, traditional tripods usually include three supporting legs and an installation platform mounted on the upper ends of the supporting legs, on which surveying and mapping equipment is installed for use. In order to meet the needs of different terrains, different supp...

Problems solved by technology

For the method of bolt locking, the bolt needs to be loosened and tightened every time the length is adjusted, which is inconvenient to use when the adjustment is relatively frequent. At the same time, after long-term use, the locking degree is often reduced due to loose bolts. Affects normal surveying and mapping; for the method of locking with elastic buttons, the adjustment range is mainly controlled by the button hole that is matched with the setting, and stepless adjustment cannot be achieved, and the adjustment range is limited
