Description

Technical Field

[0001] This utility model relates to the field of total station supporting technology, specifically a total station leveling device. Background Technology

[0002] A total station, also known as a total station electronic distance measuring instrument, is a high-tech surveying instrument integrating optics, mechanics, and electronics. It integrates functions for measuring horizontal angles, vertical angles, distances (slope distance and horizontal distance), and elevation differences, enabling three-dimensional positioning and data processing. By combining the functions of an electronic theodolite and an electronic distance measuring instrument with photoelectric scanning angle measurement systems and electronic distance measuring technology, the total station significantly improves the accuracy and efficiency of measurements.

[0003] Currently, the operation of a total station requires first placing the tripod support blocks on the ground, then coarsely aligning the top plate of the tripod with the ground marker. This process inevitably involves moving the tripod multiple times. After the instrument is installed, it is necessary to align the eyepiece center of the centering device with the ground marker again. The entire operation is very inconvenient and the leveling efficiency is low. Furthermore, existing total stations still rely on manual adjustment of the leveling screws, which further increases installation time and reduces leveling efficiency. Therefore, a base device that can automatically level the total station is needed to maximize the efficiency of leveling and installation. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a total station leveling device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A total station leveling device includes a base, a chassis seat fixedly mounted on the top of the base, a plurality of first telescopic components equidistantly arranged around the top edge of the chassis seat with their telescopic direction perpendicular to the upper surface of the chassis seat, a top seat arranged directly above the chassis seat, and an instrument mounting seat coaxially arranged on the top seat. The telescopic ends of the first telescopic components are movably connected to the lower surface of the top seat. A plurality of second telescopic components that telescopic in their radial direction are evenly distributed on the outer periphery of the instrument mounting seat, and the telescopic ends of the second telescopic components are movably connected to the outer periphery of the instrument mounting seat. The total station is mounted on the instrument mounting components.

[0007] Furthermore, the first telescopic assembly includes a first telescopic electric cylinder, the bottom end of which is movably connected to a plurality of feet fixed to the edge of the top surface of the chassis seat in an upward ring.

[0008] Furthermore, the top seat is an annular top seat, the instrument mounting base is placed inside the annular top seat, and the outer peripheral sidewall of the instrument mounting base is movably connected to the telescopic end of the second telescopic component.

[0009] Furthermore, the second telescopic assembly includes a second telescopic electric cylinder, the cylinder of which is connected to the annular top seat, and the telescopic end of which is movably connected to the outer peripheral sidewall of the instrument mounting base.

[0010] Furthermore, multiple shaft lugs are evenly fixed on the outer peripheral sidewall of the instrument mounting base, and multiple shaft holes with vertically arranged axes are opened on the annular top seat. A rotating shaft that is rotatably installed inside the shaft hole is vertically fixed on the front end of the bottom wall of the second telescopic electric cylinder, and the piston rod end of the second telescopic electric cylinder has a collar that is horizontally rotatably connected to the shaft lugs.

[0011] Furthermore, the bottom of the cylinder of the first telescopic electric cylinder is connected to the foot screw via the first universal joint, and the top piston rod end of the first telescopic electric cylinder is connected to the bottom of the annular top seat via the second universal joint.

[0012] Furthermore, a plurality of hinges are evenly distributed around the bottom edge of the base, and an adjustable support leg is mounted on the inner side of the hinge at the upper end.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this total station leveling device, the adjusting legs are first extended and supported on the ground, so that the tripod base is approximately directly above the ground mark. Then, leveling is initiated. At this time, the control box can obtain the horizontal angle status of the annular top seat through the feedback of the angle sensor, and control the three first telescopic electric cylinders to extend and retract until the annular top seat and the instrument are in a horizontal state. Then, centering adjustment begins, and with the cooperation of the extension and retraction of the three second telescopic electric cylinders, the instrument mounting base makes a small horizontal displacement in the inner diameter area of ​​the annular top seat until the infrared line at the bottom of the total station coincides with the ground mark.

Detailed Implementation

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Figures 1-3 The diagram shown is a complete structural schematic of a total station leveling device according to this utility model. Please refer to [link / reference]. Figures 1-3This embodiment of a total station leveling device includes a tripod base 100, a chassis 200 fixedly mounted on the top of the tripod base 100, three leveling screws 300 equidistantly arranged around the top edge of the chassis 200, a first telescopic electric cylinder 310 movably mounted on the leveling screws 300, an annular top seat 400 arranged directly above the chassis 200, the bottom edge of the annular top seat 400 being movably connected to the top output end of the first telescopic electric cylinder 310, an instrument mounting base 500 horizontally arranged at the center of the annular top seat 400, the total station being mounted on the top of the instrument mounting base 500, the instrument mounting base 500 and the tripod base 100 both having centering holes along their central vertical lines, and three equidistantly distributed second telescopic electric cylinders 600 horizontally rotatably mounted around the upper edge of the annular top seat 400, with the piston rod ends of the second telescopic electric cylinders 600 being horizontally rotatably connected to the bottom edge of the instrument mounting base 500.

[0024] The tripod base 100 has three hinges evenly distributed around its bottom edge, and adjustable legs 110 mounted on the inner side of the hinges at the top. It can be understood that the adjustable legs 110 are the tripods used in existing total station equipment, and their length is adjustable; further details are omitted. The base 200 has a first centering hole 210 at its central axis, the instrument mounting base 500 has a second centering hole 510 at its central axis, and the tripod base 100 also has a centering hole at its central axis. These corresponding centering holes allow the infrared or centering mirror at the bottom of the total station to see and aim at ground markers. A universal joint 320 connects the bottom of the cylinder of the first telescopic electric cylinder 310 to the foot screw 300, and a universal joint 330 connects the top piston rod of the first telescopic electric cylinder 310 to the bottom of the annular top seat 400. With the cooperation of universal joint 320 and universal joint 330, multiple first telescopic electric cylinders 310 can form any angle with the annular top seat 400 during adjustment, ensuring smooth adjustment. Three lugs 520 are evenly fixed around the edge of the instrument mounting base 500, and three shaft holes 410 are vertically opened around the edge of the annular top seat 400. A rotating shaft 610, rotatably mounted inside the shaft hole 410, is fixed to the front end of the bottom of the cylinder of the second telescopic electric cylinder 600. The piston rod end of the second telescopic electric cylinder 600 has a collar 620 that is horizontally rotatably connected to the lugs 520. The second telescopic electric cylinder 600 serves to horizontally support the instrument mounting base 500 and can also fine-tune its horizontal orientation. A level bubble 700 and an angle sensor 710 are also respectively installed on the annular top seat 400, and a control box 800 is installed on the chassis base 200. It is understandable that the control box 800 here has a built-in battery and control processing module. The control box 800 can autonomously control the first telescopic electric cylinder 310 and the second telescopic electric cylinder 600 based on the information feedback from the angle sensor 710. In addition, the level bubble 700 allows the operator to visually observe from a physical perspective whether the annular top seat 400 and the total station are in a horizontal state.Specifically, in this embodiment, during use, the adjusting legs 110 are first extended and supported on the ground, so that the tripod base 100 is approximately directly above the ground marker. Then, leveling is initiated. At this time, the control box 800 can obtain the horizontal angle of the annular top seat 400 through the feedback of the angle sensor 710, and control the three first telescopic electric cylinders 310 to extend and retract until the annular top seat 400 and the instrument are in a horizontal state. Then, centering adjustment begins, and with the extension and retraction of the three second telescopic electric cylinders 600, the instrument mounting base 500 makes a small horizontal displacement in the inner diameter area of ​​the annular top seat 400 until the infrared line at the bottom of the total station coincides with the ground marker. This completes the leveling and installation of the instrument. In summary, this total station leveling device does not require multiple movements of the tripod during leveling and erection. After the initial erection, the leveling device can automatically perform leveling and centering operations, effectively reducing installation time and improving leveling efficiency.

[0025] As a preferred embodiment, further, based on the above-described embodiments, when the first telescopic electric cylinder 310 or one of the telescopic electric cylinders malfunctions, the user can also manually level the annular top seat 400 and the total station using the foot screw 300 and the level bubble 700, thus achieving automated leveling while maintaining the traditional manual adjustment method.

[0026] In summary, the total station leveling device of this embodiment, when in use, first unfolds the adjusting legs 110 and supports them on the ground, so that the tripod base 100 is approximately directly above the ground marker. Then, leveling is initiated. At this time, the control box 800 can obtain the horizontal angle status of the annular top seat 400 through the feedback of the angle sensor 710, and controls the three first telescopic electric cylinders 310 to extend and retract until the annular top seat 400 and the instrument are in a horizontal state. Then, centering adjustment begins, and with the extension and retraction of the three second telescopic electric cylinders 600, the instrument mounting base 500 makes a small horizontal displacement in the inner diameter area of ​​the annular top seat 400 until the infrared line at the bottom of the total station coincides with the ground marker. In this way, the leveling and installation of the instrument is completed. In summary, this total station leveling device does not require multiple movements of the tripod during leveling and erection. After the initial erection, the leveling device can automatically perform leveling and centering operations, effectively reducing the installation time.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation.
