Problems solved by technology

[0004] However, the surveying and mapping equipment is all installed on the top of the centering rod, but only one surveying and mapping instrument can be assembled on the top of a centering rod and can only perform one surveying and mapping operation
If there are many surveying and mapping projects, the operation time for the same surveying and mapping point will be very long, time-consuming and laborious; and when changing the surveying and mapping project, it is necessary to re-adjust the parameters, which increases the adjustment intensity, but still has surveying and mapping accuracy. Deviations affect the accuracy of the overall surveying and mapping results
[0005] In addition, the centering rod not only plays a certain centering role, but also plays an important supporting role. However, if it is used for a long time, the accuracy of the centering rod will be limited and the stability will be reduced.

Abstract

The invention discloses a surveying and mapping support frame, which comprises a centering rod and at least two support bars which are connected to the centering rod through connection components and support the centering rod. The centering rod is sleeved with at least a disc, the top surface of which is provided with several circular chutes. The several circular chutes center on the center of a circle of the disc and are respectively distributed along circumferences of different radiuses. A sliding block capable of slipping along the corresponding circular chute is arranged inside the circular chute. The sliding block is provided with a surveying and mapping instrument connecting base. The invention provides a surveying and mapping support frame which has a simple structure, is convenient to operate, is easy to manufacture, is safe and reliable, and has strong practicality. Multiple surveying and mapping operations can be carried out at a same surveying and mapping point, and operation efficiency is high. In addition, surveying and mapping results are accurate. The device is firm and reliable, and has good stability.

Description

Technical field [0001] The invention relates to a supporting device, in particular to a supporting frame for surveying and mapping, and belongs to the technical field of auxiliary equipment for surveying and mapping. Background technique [0002] As an indispensable centering device in surveying and mapping, the centering pole for surveying and mapping has a wide range of uses in surveying and mapping. It is a telescopic metal pole that can directly point to the ground marking point in a vertical direction. [0003] The existing centering rods have many specifications, generally 2.15 meters, 2 meters, 3 meters, 5 meters and other different height specifications. Although the existing centering rods have been made into telescopic metal rod structures, their general performance has been improved from the height. . [0004] However, the surveying and mapping equipment is installed on the top of the centering pole, and only one surveying and mapping instrument can be installed on the to...
