Marking pin device of theodolite, and use method thereof

Abstract

The invention provides a marking pin device of a theodolite, and a use method thereof, and relates to the technical field of surveying and mapping. The device comprises a marking pin box, a top movingdevice, a string, a laser plumb bob, a bottom circle device, a bottom edge jack, a bottom baffle, a top jack and a calibration chute. The method comprises the steps of: selecting the marking pin boxaccording to the terrain of a point to be measured, and putting the marking pin device at the point to be measured; adjusting the bottom circle device, so that the intersection point thereof is superposed with the point to be measured; moving the top moving device, so that the laser point of the laser plumb bob is superposed with the point to be measured while being still; fixing the top moving device by using a standby pin; releasing the string, so that the laser plumb bob slides to the ground, completing centring, and locking the measured slope; taking down the laser plumb bob, and putting amarking pin rod into the marking pin device; and obtaining a horizontal angle and a vertical angle between points to be measured. By means of the method in the invention, a measurement point can be centred precisely and vertically; furthermore, a blocking problem is effectively solved; the method also can be used for evening measurement; and the method has wind resistance.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping, in particular to a theodolite brazing measuring device and a using method thereof. Background technique [0002] At the construction site, the theodolite is widely used as an important instrument; at the same time, in the use of the theodolite, it must be supplemented with a measuring rod as a measuring guideline; In addition, there are pencils; the use of the above-mentioned measuring rods will cause the following problems: artificial support has low centering accuracy and high strength; the visible length of the measuring rod is easily affected by the height of the surveyor and the available length of the measuring rod itself, and it is easy to be blocked Wait. The improved theodolite brazing device provided by the invention can effectively solve these problems. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides ...
