Problems solved by technology

[0003] (1) Since the measuring instrument is placed on the base and separated from the ground measurement mark points, time-consuming and laborious adjustments are required during the measurement to ensure that the vertical axis of the measuring instrument coincides with the vertical line passing through the measurement mark points, and the measurement instrument needs to be observed The vertical distance between the reference plane and the ground marker points, these links increase the difficulty of measurement and reduce work efficiency, and reduce the accuracy of measurement due to many error sources
[0004] (2) It cannot be applied to cylindrical measuring facilities such as leveling rods, total station reflecting prism poles, GPS (Global Satellite Positioning System) surveying poles, etc. Time-consuming and labor-intensive, and it is difficult to ensure accurate leveling, thereby reducing the accuracy of measurement

Embodiment 1

[0015] Such as figure 1 , 2 , Shown in 3 and 4: same as the prior art, there is a base 1 arranged horizontally and a foot 2 connected with the base 1, what is different from the prior art is that the base 1 is annular, and in the annular At least three horizontal jacking wires 3 are evenly distributed on the base 1 , that is, the horizontal jacking wires 3 are located on the horizontal plane of the annular base 1 . The ring-shaped base 1 can be a closed integrated structure, or an open and closed split structure, and can be in various shapes at the same time, such as figure 2 It is shown as a circle, and four top wires 3 are evenly distributed on the circumference, such as image 3 Shown as a triangle, a top wire 3 is set on each side of the triangle, as Figure 4 Shown is a quadrilateral with a top wire 3 provided on each side of the quadrilateral.

[0016] Using Embodiment 1 of the present invention as Figure 5 As shown: the leveling rod, total station reflective pris...

Embodiment 2

[0018] Such as Figure 6 Shown: the basic structure is the same as that of embodiment 1, and the difference from embodiment 1 is that there is an instrument support rod 4 built into the annular base 1, and an instrument mounting seat 5 is connected to the end of the instrument support rod 4, and the side of the instrument support rod 4 is marked with Altitude scale6. The instrument mount 5 is the same as the existing tripod, and is made of plate bases and fixings such as screws.

[0019] Place the instrument support rod 4 on the measurement mark point, adjust the flare angle and length of the foot 2, make the instrument support rod 4 stable and roughly vertical, and fix the measuring instruments such as theodolite, level and total station on the instrument mounting base 5 , Fine-tune the top wire 3 to accurately level the measuring instrument. Through the height scale 6 on the side of the instrument support rod 4, the vertical distance between the instrument observation refe...

Embodiment 3

[0021] Such as Figure 7 , Figure 8 Shown: the basic structure is the same as that of Embodiment 1, and the difference from Embodiment 1 is that the first shaft 7 is flexibly connected to the first inner ring 8 on the inner lateral side of the annular base 1, that is, the first inner ring 8 can The base 1 rotates around the first shaft 7; the lateral inner side of the first inner ring 8 connects with the second inner ring 10 through the second shaft 9, that is, the second inner ring 10 can be inside the first inner ring 8 with the first The two shafts 9 rotate, the first shaft 7 and the second shaft 9 have a difference of 90 degrees in the transverse direction, and at least three horizontal jacking screws 3 are evenly distributed on the first inner ring 8 and the second inner ring 10 . In order to facilitate the installation and operation of the jacking wire 3 , the heights of the annular base 1 , the first inner ring 8 and the second inner ring 10 are successively increased...

Abstract

The invention discloses a sleeve clip type measurement tripod which comprises a pedestal (1) and support legs (2) connected with the pedestal (1). The pedestal (1) is annular, and at least three transversal jack screws (3) are evenly distributed on the annular pedestal (1). The measurement tripod can be applied to columnar measurement facilities (such as a leveling rod, a reflecting prism, a marker post and so on). By adjusting the support legs and the transversal jack screws on the plane of the annular pedestal, the measurement tripod can be precisely leveled without the manual operation of a measuring operator. The measurement tripod is easy to operate and improves the measurement efficiency and precision.

Description

technical field [0001] The invention relates to a measurement auxiliary device, in particular to a clip-on type measurement tripod which is easy to operate and can effectively improve measurement efficiency and accuracy. Background technique [0002] In geodetic surveying and engineering surveying, it is necessary to place measuring instruments such as theodolite, level, and total station on the tripod. On the one hand, the measuring range of the instrument can be expanded, and on the other hand, it is convenient for the surveyor to operate the instrument. Existing tripod also claims tripod, has base, and base is flat plate shape, is provided with fixing parts such as vertical screw at the center of base, is connected with base and has three legs, the length of legs and base. The angle between the seats can be adjusted. When measuring, fix the measuring instrument on the base with screws, etc., and adjust the length and angle of the feet so that the reference plane of the m...
