[0026] Figure 1 The structural schematic diagram of an embodiment of the present utility model is shown, specifically showing the structure of this embodiment. This embodiment relates to a measurement auxiliary tool for a continuous casting machine, which can be installed on the conical and trapezoidal inverted grooves of the processing surface of the segment base frame, and can make the center of the spherical prism coincide with the center of the groove. By using the spherical prism for measurement, the total station can accurately locate the three-dimensional coordinate data of the groove and the processing surface, accurately measure the axial and elevation coordinate data of the positioning groove, and compare the measurement data of the positioning pin with the design data to perform the positioning and adjustment of the entire basic frame. With this method, the work can be completed quickly and well, saving manpower and time, improving the efficiency several times, and effectively improving the project quality.

[0027] A measurement auxiliary tool for a continuous casting machine, as Figure 1-2 shown, includes a spherical prism 1 for measurement and a measurement auxiliary tool 2, which can be fixed in the positioning groove 3 of the segment base. Among them, 1 is a spherical prism, and the spherical prism is a special reflection prism used for measurement; it is a metal sphere of a certain size, with a window opened, and a three-sided reflection prism is installed inside, and the center of the prism is concentric with the metal sphere; there are various size models of the spherical prism.

[0028] 2 is the main body part of the tool, which is in the shape of a frustum of a cone. To ensure the measurement accuracy, this main body part of the tool is a precision-machined metal part. Its lower conical part is a hollow sleeve with the same size as the positioning slot of the segment, which is used for inlaying and fixing on the positioning slot and has an interference fit with the positioning slot to ensure the coaxiality of the spherical mirror and the positioning pin; the middle part is a flange structure, and the processing accuracy must be ensured at the place where it is closely fitted with the processing surface around the slot, which is used to position the elevation of the processing surface. A 45° chamfer is opened at the upper end for placing the spherical mirror, which can make the spherical mirror be closely connected and rotatable in all directions here. It can also make the center of the spherical mirror concentric with the center line of the positioning pin during the rotation process and keep the center of the spherical mirror stationary.

[0029] This auxiliary tool is integrally machined from round steel, and the machining accuracy is required to be ensured. The material of the auxiliary tool can be selected as stainless steel material so that it can be used for multiple projects.

[0030] Use of the special base for spherical prism: After the basic frame is installed, insert the special base for spherical prism into the slot of the frame, which has an interference fit with the slot; place the spherical prism on the 45° chamfer at the other end, so that the spherical prism is closely connected and rotatable in all directions here. It can also make the center of the spherical prism concentric with the center line of the positioning pin during the rotation process and keep the center of the spherical prism stationary, and make the window of the spherical prism face the total station; at this time, the total station can accurately position and measure the spherical prism, accurately measure the axial and elevation coordinate data of the positioning pin, and compare the measured data of the pin with the design data. After calculating the adjustment amount, perform the positioning and adjustment of the entire basic frame. This method is used repeatedly until the installation accuracy of the basic frame meets the design requirements.

[0031] This auxiliary measuring tool - the special base for spherical prism - is simple, intuitive, and fast in installing and adjusting the base of the segment basic frame for positioning the pin of the continuous casting machine, and plays an important role - connecting the equipment data and the measurement data of the total station, which can greatly save the installation and adjustment construction period and labor input, and can also effectively improve the installation accuracy of the frame base.

[0033] 1) Fabricate the tool parts 1 and 2 according to the detailed drawings and the specific dimensions of the segment base slot.

[0034] 2) Clean the surface of the positioning slot of the segment base of part 3, place part 2 on part 3, and then place part 1 on part 2 to complete the positioning.

[0035] 3) Adjust the total station, input the coordinate position and observe part 1 for reading.

[0036] 4) Then, install parts 2 and 1 at another point card slot position on the segment base according to the method in step 2.

[0037] 5) Continue to observe with the total station, compare the measured values with the designed values and make adjustments.

[0038] 6) Complete the alignment of the segment base.

[0039] The present invention mainly makes full use of the principle that the center positioning of the spherical prism remains unchanged, and then uses the T-shaped positioning principle of the auxiliary tool for measurement to achieve the purpose of accurate measurement, ensuring the installation speed and its center positioning.

[0040] The advantages and positive effects of the present utility model are as follows: By adopting the above technical solution, making full use of the principle that the center positioning of the spherical prism remains unchanged and then using the T-shaped positioning principle of the auxiliary tool for measurement, the purpose of accurate measurement accuracy is achieved; it is simple to manufacture and can be reused; the operation is simple and the usage method can be quickly mastered, making the installation alignment more convenient and fast; it saves manpower and material resources, and realizes green environmental protection construction, thus achieving cost reduction and efficiency increase.
