Abstract

The invention discloses an adjustable measurement point aligning and lofting device, i.e. an adjustable precise lofting device. The adjustable precise lofting device consists of a substrate, upright tubes, a connecting sleeve, a connecting rod, a plurality of regulating and braking handles and connection bolts. The device adopts an original combined structure of a cross-shaped linkage shaft and a dangling pointer to realize the quick alignment of each upright tube, and the upright tubes can be freely regulated between left and right, between front and back and between top and bottom. As a point aligning tool, the device can be used for lightly, visually and stably aligning the point. As a lofting tool, the device can be cooperated with a total station to quickly and accurately position a surveying point, and also can be cooperated with a satellite positioning receiver to serve as a moving station, so as to realize GPS-RTK (global positioning system- real time kinematic) quick lofting. The adjustable precise lofting device has the advantages of convenience in carrying, flexibility in operation, visual point alignment and high lofting speed, can be widely applied to the fields such as the control measurement, the construction lofting and deformation monitoring of industrial and civil buildings, urban mass transit engineering, high speed railways and the municipal engineering, the labor intensity is lightened, and the lofting measurement efficiency and precision can be improved.

Description

technical field [0001] The invention relates to a measuring tool applied in the field of engineering surveying, in particular to an adjustable precision staker. Background technique [0002] In the field of measurement, the common tools used together with the total station for engineering stakeout include: centering rod with bracket, small single rod prism, combination of tripod and target plate, among which the bracket centering rod with adjustable legs is commonly used , and with two legs is the most common, but the operation of the centering rod is cumbersome and the stakeout accuracy is low; the distance from the total station to the total station should not be too far when the single rod small prism is used; Inconvenient to carry, complicated and time-consuming to operate. [0003] The Chinese patent whose publication number is CN202171456U discloses a quick staker, which includes a sleeve, a laser emitter is arranged inside the sleeve, and a control switch is arranged...
