Embodiment Construction

[0028] This device has two purposes, one is used as a point alignment and aiming tool, and it is erected on an existing point on the ground for orientation or control measurement and observation; Carry out engineering stakeout. The operation is relatively simple when used as a pointing and aiming tool, and slightly complicated when used as a stakeout tool, which will be introduced in detail below.

[0029] When the device was used as a pointing and aiming tool, the accessory prism (15) can be omitted, and a supporting target plate can be installed on the accessory prism (16) to increase the aiming accuracy. The operation can be divided into four steps: placing, straightening, centering and aiming, such as Figure 12 to Figure 15 Shown:

[0030] The first step: placement. The operator holds the upper handle of the support rod (1), lightly places the device near the existing point (set as P1) on the ground, and sets it as point A, so that the bottom of the base touches the gr...

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 device for measuring alignment and setting out, which is an adjustable precise setting out device. As a point-setting tool, this device can realize light, intuitive, and stable point-pointing; as a stakeout tool, it can be used with a total station to realize fast and accurate positioning of surveying points, and can also be used as a rover with a satellite positioning receiver , to achieve GPS-RTK rapid stakeout. It is easy to carry, flexible to operate, intuitive to point alignment, fast to set out, reduce labor intensity, and improve the efficiency and accuracy of measurement and set out. It can be widely used in industrial and civil buildings, urban rail transit engineering, high-speed railway, municipal engineering control measurement, construction stakeout and deformation monitoring and other fields. Background technique [0002] Conventional ground point centering and aiming devices use an optical base and a matching...
