Description

Technical Field

[0001] This utility model relates to the field of engineering surveying technology, specifically an auxiliary tool for coordinate setting out of a total station. Background Technology

[0002] A total station is a high-tech surveying instrument that integrates optics, mechanics, and electronics. It has functions for measuring horizontal angles, vertical angles, distances (slope distance, horizontal distance), and elevation differences. It can automatically display observation data, such as slope distance, zenith distance (vertical angle), and horizontal angle, and obtain the horizontal distance, elevation difference, and coordinates of the point almost simultaneously. It is an important tool for precision engineering surveying or deformation monitoring in the construction of large above-ground buildings and underground tunnels. For example, large components require high hoisting accuracy, so a total station needs to be equipped with a prism to measure the hoisting points.

[0003] In existing technologies, prisms are used when conducting engineering surveying and setting out. The prisms can reflect light signals (such as laser or infrared light) from the total station. These reflected light signals are the basis for the total station to perform distance measurements. By reflecting light signals, the total station can directly measure the location of the prism, which greatly simplifies the measurement process, reduces human error, and improves the accuracy and reliability of the measurement.

[0004] However, the existing technology has the following problems: when hoisting large hollow components, the hoisting center point of the component is located on the ground of the prism pole. Since the prism is not easy to disassemble, it is difficult to measure the edge line of the component being hoisted with a tape measure, which affects the installation accuracy of the component.

[0021] See Figure 1 , Figure 2 and Figure 5 In this embodiment of the utility model, an auxiliary tool for coordinate layout of a total station includes a prism positioning structure 1. The prism positioning structure 1 includes a metal disc 2, with an insertion hole 201 at the center of the top of the metal disc 2, a cylindrical column 305 fixedly installed at the bottom of the metal disc 2, a prism 3, the prism 3 being installed at the top of the metal disc 2, a guide post 301 being rotatably installed at the bottom of the prism 3, a first magnet 303 being fixedly installed at the bottom of the guide post 301, a second magnet 304 being fixedly installed at the bottom of the inner side of the cylindrical column 305, the guide post 301 being slidably installed on the inner side of the cylindrical column 305, a sliding groove 302 being symmetrically opened on the outer side of the guide post 301, a guide rail 306 being symmetrically arranged on the inner side of the cylindrical column 305, a large hollow component 6 being arranged on the outer side of the prism positioning structure 1, and the metal disc 2 and the large hollow component 6 being arranged at the same horizontal level.

[0022] Once the prism positioning structure 1 is in position, the prism 3 can be removed directly. Since the guide post 301 is attracted by the first magnet 303 and the second magnet 304, installation and disassembly are convenient. The large hollow component 6 is hoisted on the outside of the prism positioning structure 1 by a crane. The metal disc 2 and the large hollow component 6 are set at the same level. At this time, the distance between the center point and the large hollow component 6 is measured with a tape measure. The measurement is carried out in a circumferential distribution and is performed at least three times, which can improve the installation accuracy and efficiency of the large hollow component 6.

[0023] See Figure 4The inner side of the socket 201 is symmetrically provided with a storage groove 202. The inner side of the storage groove 202 is rotatably set on the calibration claw 5. The two sides of the mutually distant ends of the calibration claw 5 are fixedly provided with torsion springs 501. The other end of the torsion spring 501 is fixedly set on the inner side of the storage groove 202.

[0024] After the prism 3 is removed, the calibration claw 5 will return to a horizontal state from the storage slot 202 by the elastic force of the torsion spring 501. The intersection of the two calibration claws 5 is the center point to be located, which makes it easy to find the center point during measurement.

[0025] See Figure 1 , Figure 2 and Figure 3 Below the metal disc 2, there is an adjusting vertical cylinder 4. One end of the adjusting vertical cylinder 4 is rotatably equipped with an adjusting ring 401. The inner side of the adjusting ring 401 is threadedly connected to an adjusting screw 402. The adjusting screw 402 is fixedly installed at the bottom end of the cylinder column 305 and is located inside the adjusting vertical cylinder 4. The other end of the adjusting vertical cylinder 4 is fixedly equipped with a fixing block 403. The outer side of the fixing block 403 is rotatably equipped with an adjusting support arm 4031. The other end of the adjusting support arm 4031 is rotatably equipped with a leg 404. The leg 404 is rotatably installed at the bottom end of the metal disc 2. There are three adjusting support arms 4031 and three leg 404. The other side of each leg 404 is equipped with a bubble level 405. The inner side of the leg 404 is threadedly connected to a leveling stud 407. One end of the leveling stud 407 is fixedly equipped with a foot 406.

[0026] The prism positioning structure 1 is placed on the ground. The position of the prism positioning structure 1 is determined by a total station. When placing the prism positioning structure 1, the length between the adjusting cylinder 4 and the adjusting screw 402 is shortened by rotating the adjusting ring 401. This causes the three adjusting arms 4031 to expand and open, allowing the tripod legs 404 to open outwards. This allows the prism positioning structure 1 to stand stably on the ground. By observing the bubbles in the three bubble levels 405, it is determined whether the metal disc 2 is level. If the bubbles in the three bubble levels 405 are not in the same position, the leveling stud 407 can be raised or lowered by rotating the foot 406. This increases or decreases the length between the tripod legs 404 and the foot 406, allowing for fine-tuning of each tripod leg 404 to achieve the effect of leveling the metal disc 2 and improving the positioning accuracy of the prism positioning structure 1.

[0027] The working principle of this utility model is as follows: The prism positioning structure 1 is placed on the ground, and the position of the prism positioning structure 1 is determined by a total station. When placing the prism positioning structure 1, the length between the adjusting vertical cylinder 4 and the adjusting screw 402 is shortened by rotating the adjusting ring 401, thereby causing the three adjusting arms 4031 to expand and open, so that the tripod legs 404 open outward, allowing the prism positioning structure 1 to stand stably on the ground. By observing the bubbles in the three bubble levels 405, it is determined whether the metal disc 2 is level. If the bubbles in the three bubble levels 405 are not in the same position, the leveling stud 407 can be raised or lowered on the inner side of the bottom of the tripod leg 404 by rotating the foot 406, thereby lengthening or shortening the length between the tripod leg 404 and the foot 406. Each tripod leg 404 can be finely adjusted to achieve the effect of leveling the metal disc 2 and improve the positioning accuracy of the prism positioning structure 1.

[0028] Once the prism positioning structure 1 is positioned, the prism 3 can be removed directly. Since the guide post 301 is attracted by the first magnet 303 and the second magnet 304, installation and disassembly are convenient. After the guide post 301 leaves the cylindrical shell post 305, the calibration claw 5 will return to the horizontal state from the storage slot 202 by the elastic force of the torsion spring 501. The intersection of the two calibration claws 5 is the center point of the positioning. The large hollow component 6 is hoisted on the outside of the prism positioning structure 1 by a crane. The metal disc 2 and the large hollow component 6 are set at the same horizontal level. At this time, the distance between the center point and the large hollow component 6 is measured by measuring tape. The measurement is carried out in a circumferential distribution and is measured at least three times, which can improve the installation accuracy and efficiency of the large hollow component 6.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
