Description

Technical Field

[0001] This utility model relates to the field of prisms for surveying total stations, specifically a telescopic combination prism. 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 is a surveying instrument system that integrates the functions of measuring horizontal angles, vertical angles, distances (slope distances, horizontal distances), and elevation differences. Compared with optical theodolites, electronic theodolites replace the optical scale with a photoelectric scanning scale, and replace manual optical micrometer readings with automatic recording and display of readings, simplifying angle measurement operations and avoiding reading errors. Because it can complete all measurement work at a station with a single instrument setup, it is called a total station. It is widely used in precision engineering surveying or deformation monitoring fields such as large-scale above-ground construction and underground tunnel construction. The working principle of a total station is roughly as follows: the total station emits a laser or infrared emitter towards a prism, which then reflects the light back through a reflecting prism. The computer inside the total station calculates the target's coordinates based on the angle and distance of the light beam and stores the data in memory. Through continuous measurement, the three-dimensional coordinates of the target in space can be obtained.

[0003] According to the published patent 202322230420.6, a prism assembly for a total station, it includes a bracket with a fixed frame mounted on the upper end. The prism body is housed within the fixed frame and is rotatably connected to the fixed frame. A movable platform is located on one side of the fixed frame, connected to the prism body's mount. An aiming device is located on the side of the movable platform away from the fixed frame, with its axis parallel to the prism body's axis. The aiming device is detachably fixed to the movable platform. This prism assembly allows the surveyor at the designated location to independently adjust the prism's angle and position, eliminating the need for communication with the total station personnel, effectively expanding the surveying work area, and thus improving surveying efficiency.

[0004] However, in practice, traditional prism assemblies cannot complete measurements when using a total station because the line of sight between the total station and the prism is obstructed. Furthermore, the fixed angle of a single prism limits its measurable range, failing to meet diverse measurement needs and reducing its applicability. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a telescopic combined prism to solve the technical problems of traditional prism components, which cannot complete measurements when using a total station because the line of sight between the total station and the prism is blocked. At the same time, the fixed angle of a single prism limits its measurement range and cannot meet diverse measurement needs, thus reducing the applicability of a single prism.

[0006] To solve the above problems, the present invention adopts the following technical means:

[0007] A telescopic combination prism includes a rod, the top of which has a circumferential adjustment mechanism coaxially mounted. Several telescopic components are coaxially rotatably mounted on the circumferential adjustment mechanism, and a prism adjustment assembly is mounted on the end of each telescopic component away from the rod.

[0008] Preferably, the circumferential adjustment mechanism includes a fixed cylinder coaxially disposed at the top of the insertion rod, and a plurality of annular grooves extending along the axial direction are coaxially formed on the surface of the fixed cylinder. A first damping bearing is installed inside the annular grooves, and a telescopic component is installed on the outer wall of the first damping bearing.

[0009] Furthermore, the telescopic component includes a first telescopic cylinder and a second telescopic cylinder that are nested together. A fixing bolt passes through the top of the first telescopic cylinder, and multiple threaded grooves are opened on the surface of the second telescopic cylinder. One end of the fixing bolt located inside the first telescopic cylinder is threadedly connected to the threaded groove.

[0010] Furthermore, the prism adjustment assembly includes a circular groove, a second damping bearing, a first rotating rod, a concave frame plate, a mounting groove, a third damping bearing, a second rotating rod, and a prism body.

[0011] Furthermore, a circular groove is formed on the surface of the second telescopic cylinder, and a second damping bearing is installed inside the circular groove. The top of the second damping bearing is rotatably connected to the first rotating rod, and a concave frame plate is installed on the top of the first rotating rod.

[0012] Furthermore, mounting grooves are provided on both sides of the inner wall of the concave frame plate. A third damping bearing is installed inside the mounting groove. One end of the second rotating rod is rotatably connected inside the third damping bearing, and the other end of the second rotating rod is installed with the prism body.

[0013] This utility model has the following beneficial effects during use:

[0014] Firstly, by combining the first damping bearing, the telescopic component, and the prism adjustment assembly, multiple prisms can be simultaneously set up to achieve adjustments at different positions. Moreover, the telescopic component allows for the telescopic adjustment of multiple prisms. Furthermore, the second damping bearing enables the adjustment of the prism angle, thus realizing multiple adjustment methods for multiple prisms. This effectively expands the effective illumination area of ​​the prism, achieving the purpose of measuring obstructed objects. It solves the technical problems that prevent measurement when using a total station because the line of sight between the total station and the prism is obstructed, and that the fixed angle of a single prism limits its measurement range, failing to meet diverse measurement needs and reducing the applicability of a single prism.

[0015] Secondly, by combining the fixed cylinder, the circular groove, and the laser emitter, when the prism assembly is fixed on the ground, the laser emitter can shoot a laser upwards. By observing the position of the laser, the staff can quickly locate multiple prism assemblies and thus quickly perform measurements. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please refer to Figures 1 to 3 As shown, a telescopic combination prism includes a rod 1. The top end of the rod 1 is coaxially equipped with a circumferential adjustment mechanism. Several telescopic components are coaxially rotatably mounted on the circumferential adjustment mechanism. A prism adjustment component is installed at the end of each telescopic component away from the rod 1.

[0027] Specifically, the aforementioned circumferential adjustment mechanism includes a fixed cylinder 2 coaxially mounted at the top of the insertion rod 1. The surface of the fixed cylinder 2 has multiple annular grooves 201, and a first damping bearing 202 is installed inside each annular groove 201. A telescopic component is fixed to one end of the first damping bearing 202, and a prism adjustment assembly is located at the end of the telescopic component away from the first damping bearing 202. When the position of multiple prism bodies 206 needs to be adjusted, the telescopic component can be moved directly. The telescopic component rotates through the first damping bearing 202, thereby adjusting the overall position of the prism bodies 206. When there is an obstruction, the position of the multiple prism bodies 206 can be adjusted to avoid the obstruction. Simultaneously, the second telescopic cylinder 204 can move within the first telescopic cylinder 203 to adjust the distance between the prism bodies 206. After adjustment, the second telescopic cylinder 204 is fixed to the first telescopic cylinder 203 using a fixing bolt 208. The threaded groove 207 on the surface of 04 is threaded to connect the second telescopic cylinder 204 and the prism body 206, thereby limiting their movement. By adjusting the distance between the prism body 206 and the obstruction, the prism body 206 can be extended to exceed the obstruction. Moreover, since a third damping bearing 213 is provided inside the circular groove 209, the concave frame plate 205 and the prism body 206 can be rotated directly to adjust the angle of the prism body 206, thereby adjusting the total station of the corresponding operator. This realizes multiple adjustment methods for multiple prisms, effectively expanding the effective illumination surface of the prism to achieve the purpose of measuring obstructions. It solves the technical problem that when using a total station for measurement, the line of sight between the total station and the prism is blocked, making it impossible to complete the measurement. At the same time, the fixed angle of a single prism limits its measurement range, which cannot meet diverse measurement needs and reduces the applicability of a single prism.

[0028] For details, see Figure 1 and Figure 2 The telescopic component includes a first telescopic cylinder 203 and a second telescopic cylinder 204 that are nested together. A fixing bolt 208 passes through the top of the first telescopic cylinder 203. The surface of the second telescopic cylinder 204 is provided with multiple threaded grooves 207. One end of the fixing bolt 208 located inside the first telescopic cylinder 203 is threadedly connected to the threaded groove 207.

[0029] Further, see Figure 2 and Figure 3 The prism adjustment assembly includes a circular groove 209, a second damping bearing 210, a first rotating rod 211, a concave frame plate 205, a mounting groove 212, a third damping bearing 213, a second rotating rod 214, and a prism body 206.

[0030] It is worth noting that, see Figure 2A circular groove 209 is formed on the surface of the second telescopic cylinder 204. A second damping bearing 210 is installed inside the circular groove 209. A first rotating rod 211 is rotatably connected to the top of the second damping bearing 210. A concave frame plate 205 is fixed to the top of the first rotating rod 211.

[0031] It is worth noting that, see Figure 3 The concave frame plate 205 has mounting grooves 212 on both sides of its inner wall. A third damping bearing 213 is installed inside the mounting groove 212. One end of a second rotating rod 214 is rotatably connected inside the third damping bearing 213. The other end of the second rotating rod 214 is fixed to the prism body 206.

[0032] It is worth mentioning that, see Figure 1 The top of the fixed cylinder 2 is provided with a groove 3, and a laser emitter 301 is installed inside the groove 3. After the prism assembly is inserted into the ground through the insertion rod 1, the laser emitter can be turned on to emit a laser beam upward. By observing the position of the laser beam, technicians can quickly and accurately identify and locate multiple prism assemblies, which greatly promotes the efficiency and speed of measurement work.

[0033] When using a telescopic combination prism, if the positions of multiple prism bodies 206 need to be adjusted, the telescopic component can be moved directly. The telescopic component rotates via the first damping bearing 202, thereby adjusting the overall position of the prism bodies 206. When there is an obstruction, the obstruction can be avoided by adjusting the positions of the multiple prism bodies 206. At the same time, the second telescopic cylinder 204 can move within the first telescopic cylinder 203 to adjust the distance between the prism bodies 206. After adjustment, the fixing bolt 208 is threaded into the threaded groove 207 on the surface of the second telescopic cylinder 204, thereby limiting the position of the second telescopic cylinder 204 and the prism bodies 206. After adjusting the prism bodies 206... The distance of 6 allows the prism body 206 to extend beyond the obstruction. Moreover, due to the third damping bearing 213 installed inside the circular groove 209, the concave frame plate 205 and the prism body 206 can be rotated directly, and the angle of the prism body 206 can be adjusted, thereby adjusting the total station of the corresponding personnel. This realizes multiple adjustment methods for multiple prisms, which can effectively expand the effective illumination surface of the prism and achieve the purpose of measuring the obstruction. After the prism assembly is inserted into the ground through the insertion rod 1, the laser emitting device can be turned on to emit a laser beam upward. By observing the position of the laser beam, technicians can quickly and accurately identify and locate multiple prism assemblies, which greatly promotes the efficiency and speed of measurement work.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
