Description

Technical Field

[0001] This utility model relates to a device for aligning a spherical prism with the center point of a microgrid during laser tracker measurement, and a device for measuring and marking the location of stakeout points using a spherical prism. Background Technology

[0002] The nuclear reactor building of a nuclear power plant adopts modular construction, which is characterized by rapid construction progress, simultaneous construction and installation, and small working areas with significant elevation differences. This presents certain difficulties for on-site microgrid deployment. Therefore, laser trackers must be selected instead of total stations for microgrid measurement. During on-site measurement, the installation of some high-precision equipment requires the use of laser trackers for measurement and layout, and the layout points must be marked.

[0003] Before using a laser tracker for measurement, the following technical problems must be solved: (1) The spherical prism is a circular solid, and the micro-grid point is an independent point. The existing instruments and equipment make it impossible for the center points of two different shapes to coincide and be aligned; (2) The cylinder of the precision support cannot be physically connected to the spherical prism, and the two different objects cannot be concentric; (3) The actual center point of the spherical prism projection must coincide with the center point of the micro-grid and be on the same plumb line; (4) After using a laser tracker for measurement and layout, the spherical prism cannot accurately mark the point.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses consistent with some aspects of this application as detailed in the appended claims.

It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0025] Please refer to the following for details. Figure 1-6 A device suitable for point setting and layout in engineering surveying includes a main body made of 304 stainless steel and a cylindrical striker that works in conjunction with the main body. The main body has a through hole penetrating both its upper and lower surfaces. The through hole includes an upper through hole and a lower through hole, which are connected. The diameter of the upper through hole is smaller than that of the lower through hole, and their central axes coincide. The striker can be installed in the through hole. Several spherical prism support columns are provided on the outer edge of the upper end face of the main body. An upper annular magnet and a lower annular magnet are embedded in the upper and lower end faces of the main body, respectively. The upper annular magnet can attract the spherical prism to the spherical prism support column, ensuring a stable connection between the spherical prism and the main body. The lower annular magnet can attract the surface of the object to be measured (carbon steel), providing a certain degree of stability and ease of operation.

[0026] Furthermore, the firing pin is adapted to the upper through hole, one end of the firing pin is a pointed tip, the center of the pointed tip is the center of the firing pin, and the center point of the firing pin is concentric with the upper through hole and the lower through hole.

[0027] Furthermore, the inner surface of the spherical prism support column is a slope, and a certain point on the slope is the contact point with the spherical prism. The contact point between the spherical prism and the spherical prism support column is perfectly matched with its external dimensions, and the center of the spherical prism is concentric with the upper and lower through holes.

[0028] Furthermore, there are three spherical prism support columns, which are equally spaced on the main body of the device. The center of the spherical prism support column is concentric with the upper and lower through holes of the main body of the device. The top section of the spherical prism support column is perpendicular to the central axis of the upper and lower through holes and parallel to the bottom section of the main body of the device.

[0029] Use of the point-to-point device: Please refer to Figure 5 and Figure 7 First, set up a tripod and install the base and precision support. Adjust the tripod position by observing the eyepiece on the precision support, ensuring the crosshairs of the eyepiece coincide with the center of the micro-dot. Adjust the instrument's level using the tripod and leveling screws to center it. At this point, the instrument's horizontal axis is perpendicular to the vertical axis (the horizontal plane is perpendicular to the plumb line). Repeat this process until the crosshairs of the eyepiece are completely aligned with the center of the micro-dot. Next, slowly insert the lower through-hole at the bottom of the main body of the device into the cylinder of the matching precision support. The precision support is now connected to the main body of the device. At this point, the cylinder of the precision support is coaxial with the center lines of the upper and lower through-holes of the main body of the device, and the top section of the spherical prism support column is perpendicular to the center lines of the upper and lower through-holes. Then, place the spherical prism on the spherical prism support column. At this point, the position of the spherical prism and the three spherical prism support columns perfectly match its dimensions, meaning the center of the spherical prism and the center of the micro-dot are on the same plumb line and coincident.

[0030] Use of the layout device: Please refer to Figure 6 Because the spherical prism is a sphere, its location cannot be marked after on-site layout. This device can solve this problem by accurately marking the location. The spherical prism is placed on the spherical prism support column of the device body, with the bottom of the device body in contact with the surface of the object to be measured (carbon steel). By comparing the data collected by the laser tracker with the design data, the differences in ΔX, ΔY, and ΔZ values ​​at that point can be obtained. The device is moved along the X, Y, and Z directions according to the measured data until the measured data matches the theoretical data. After determining the coordinates, the spherical prism is slowly removed, and the striker is inserted into the matching through-hole to mark the layout point, thus accurately completing the point marking.

[0031] As can be seen from the above embodiments, the device of this utility model is quick to assemble, easy to operate, highly efficient, and can ensure measurement accuracy.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
