Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional coordinate detection, in particular to a high-precision three-dimensional coordinate detection device. Background Art

[0002] When checking the levelness during the fabrication and installation of large metal structures, the common methods are to use a total station with a prism or a high-precision level with a dedicated indium tile ruler. Although the first method can solve the problem of three-dimensional position detection, its disadvantage is that the levelness measurement accuracy is not high due to the axis error of the instrument and the alignment angle of the prism. Although the second method has high levelness detection accuracy, its disadvantage is that the equipment is expensive and the indium tile ruler must be equipped with a spherical point contact device.

[0003] For example, the authorization announcement number "CN206269772U" is named as a high-precision three-dimensional coordinate measuring device. By setting an LED light on the reflective mirror, the total station can quickly locate the prism, especially when the measuring point is in a darker position, the total station can also accurately locate the prism. However, the existing high-precision three-dimensional coordinate measuring device uses a leg structure that can be pulled out from the outside for support, and the vertical three-dimensional coordinate measuring device is fixed on the horizontal ground for use in conjunction with the measuring instrument to achieve measurement. However, multiple legs and ear plate sliders connecting the legs are sleeved on the outside of the main scale. The legs and ear plates will block the blocking scale at the front end of the main scale, so it is easy to cause interference and errors in actual measurement, and thus the measurement effect of the high-precision three-dimensional coordinate measuring device is affected.

[0004] At the same time, the existing high-precision three-dimensional coordinate measuring device uses LED lights to assist the reflective mirror to quickly locate the total station, but the main scale is not easy to see at night or in a dark environment. The front end of the main scale is provided with dense scale lines. Under dim conditions, the scale lines cannot be clearly and accurately represented on the total station, thereby affecting the accuracy of the reading and reducing the measurement accuracy of the high-precision three-dimensional coordinate measuring device. Utility Model Content

Both sides of the outer wall of the main scale are provided with a telescopic unobstructed fixed structure, the outer side of the main scale is provided with a fixed structure auxiliary limit structure, and the top of the main scale is provided with an illumination reading structure.

[0008] Preferably, the telescopic unobstructed fixed structure includes a positioning column and an oblique rod, the two positioning columns are fixedly connected to the two sides of the outer wall of the main scale, the lower ends of the two positioning columns are rotatably connected to two rotating shafts through bearings, the lower ends of the two rotating shafts are fixedly connected to threaded tubes, the lower ends of the two threaded tubes are threadedly connected to screws, and the bottom ends of the two screws are fixedly connected to the oblique rod.

[0009] Preferably, the auxiliary limiting structure of the fixed structure includes a slide groove and a penetration rod, the two slide grooves are fixedly opened on both sides of the outer wall of the main scale, the inner sides of the two slide grooves are slidably connected with sliders, the outer walls of the two sliders are fixedly connected to the side walls of the oblique rod, and the two penetration rods are fixedly connected to the lower end of the oblique rod.

[0010] Preferably, the illuminated reading structure includes a convex rod and a transverse plate, the two transverse plates are fixedly connected above the side wall of the main scale, the front ends of the two transverse plates are fixedly installed with convex strips, the inner walls of the convex strips are fixedly installed with lamp beads, the convex rod is fixedly installed at the front end of the outer wall of the scale plate, and multiple scale lines are fixedly connected on both sides of the convex rod.

[0011] Preferably, extension plates are fixedly connected to both sides above the main scale, and level bubbles are fixedly installed above the two extension plates.

[0012] Preferably, a support platform is fixedly mounted on the top of the main scale, and a reflective mirror is fixedly mounted on the top of the support platform.

[0013] The utility model proposes a high-precision three-dimensional coordinate detection device, which has the following beneficial effects: through the vertical excavation of the slide groove on both sides of the main scale, the slider can slide up and down along the slide groove to limit the oblique rod, and when the screw pushes the oblique rod downward to move, it can drive the metal steel driving drills on both sides to deeply penetrate into the soil. The driving drills on both sides cooperate with the positioning cone in the middle to realize the positioning and installation of the main scale. At the same time, the fixed structures arranged on both sides will not block the normal reading of the main scale, thereby improving the measurement effect of the high-precision three-dimensional coordinate detection device.

After the power is connected to start the lamp beads, the lamp beads can light up to illuminate the scale lines at the front end of the scale plate, which is convenient for cooperating with the total station to detect three-dimensional seats in dark and weak light conditions. There are two rows of scale lines on both sides of the convex strip, and the scale units of the two rows of scale lines can be selected according to use.
