Description

Technical Field

Background Art

[0002] The segment basic frame is an important equipment of the slab continuous casting machine. At present, during the installation of the segment basic frame of the slab continuous casting machine, a measurement method using a measuring wheel, a hanging wire and a micrometer (rod) is generally adopted. However, due to factors such as the placement position of the measuring wheel, the swing of the wire, and the manual operation of multi-point measurement with the micrometer, the cumulative measurement error caused is relatively large, which seriously affects the measurement accuracy. Even the deviation between the measured data and the theoretical value is relatively large, thus affecting the subsequent installation accuracy of the segment and the alignment accuracy of the entire slab continuous casting machine, all of which will affect the quality of the slabs produced by the slab continuous casting machine. Moreover, during the installation of the segment basic frame of the slab continuous casting machine, 5 - 6 people are required to operate together for about 20 days, and the overhead crane in this bay of the workshop needs to be occupied for a long time. In addition, the wires used in the measurement process are basically disposable consumables, resulting in serious waste of resources.

[0003] In order to overcome the above problems and meet the usage requirements in this engineering field, the present invention adopts a new detection means, so as to provide a fast, efficient and accurate means and method for the installation of the segment basic frame of the slab continuous casting machine, and it is more convenient, fast and accurate especially when applied to the heavy and wide slab continuous casting machine.

[0015] The specific method for measuring and positioning the first measurement axis on the segment base frame in the first step is as follows:

[0016] First step: Adjust the position of the total station so that the plane P1 formed by the original reference point, the backsight point of the total station, and the observation point of the total station is parallel to the preset continuous casting machine center plane P0, and then position the total station.

[0017] Second step: Taking the total station as the coordinate origin, establish a coordinate system with the horizontal direction perpendicular to the continuous casting machine center plane and from the first measurement axis towards the continuous casting machine center plane as the positive X - axis direction, the vertical upward direction as the positive Z - axis direction, and the horizontal direction towards the civil engineering construction foundation as the positive Y - axis direction.

[0018] Step 3: Sleeve the sleeve in the spatial arbitrary reference axis measuring and positioning device onto the first measuring axis on the segment base frame; record the central coordinates A(Xa, Ya, Za) of the first steel spherical prism in the spatial arbitrary reference axis measuring and positioning device by means of a total station; then place the fixed-distance gauge block in the sleeve and sleeve it onto the first measuring axis on the segment base frame, and then record the central coordinates B(Xb, Yb, Zb) of the first steel spherical prism in the spatial arbitrary reference axis measuring and positioning device at this time by means of a total station, calculate the distance between A and B, and when |AB| = |Za - Zb|, it is determined that the line connecting points A and B is perpendicular to plane P0; at this time, perform an initial positioning of the segment base frame along the Z axis;

[0019] Step 4: Move the segment base frame along the Z axis, continue to measure the central coordinates A(Xa, Ya, Za) of the first steel spherical prism, calculate the actual distance from point A to plane P0, and when the actual value is equal to the theoretical value, perform Z-axis positioning;

[0020] Step 5: Move the segment base frame along the Y axis, continue to measure the central coordinates A(Xa, Ya, Za) of the first steel spherical prism, calculate the actual distance from point A to plane P0, and when the actual value is equal to the theoretical value, perform Y-axis positioning;

[0021] Step 6: Move the segment base frame along the X axis, continue to measure the central coordinates A(Xa, Ya, Za) of the first steel spherical prism, calculate the actual distance from point A to plane P0, and when the actual value is equal to the theoretical value, perform X-axis positioning.

[0022] The specific method for measuring and positioning the second measuring axis placed on the segment base frame in Step 2 is as follows: Sleeve the sleeve onto the second measuring axis of the segment base frame to be detected, take the first measuring axis adjusted in accordance with Step 1 as the center, rotate the segment base frame, and measure the central coordinates C(Xc, Yc, Zc) of the first steel spherical prism at this time. After the absolute coordinate value of point C is equal to the theoretical value, fix the segment base frame.

[0023] The method for testing and adjusting the installation reference plane on the segment base frame in Step 3 is specifically as follows:

[0024] Step 1: Adjust the position of the total station so that the plane P1 formed by the original reference point, the backsight point of the total station, and the observation point of the total station is parallel to the preset continuous casting machine center plane P0. After parallelism, position the total station (3);

[0025] Step 2: Place the spatial arbitrary datum plane measuring and positioning device on the datum plane of the segment basic frame to be installed. At this time, the distance from the center of the second steel spherical prism on the spatial arbitrary datum plane measuring and positioning device to the datum plane to be measured is "H". Observe the center of the second steel spherical prism through the total station, record the relative coordinates x and y of the observation point, and calculate the deviation between the actual value and the theoretical value of the distance from the center of the second steel spherical prism to the datum plane to be measured.

[0026] Step 3: Arbitrarily select at least 3 more detection points on the datum plane to be measured, and record the coordinates of the second spherical prism corresponding to the three points: E(Xe, Ye, Ze), F(Xf, Yf, Zf), G(Xg, Yg, Zg); calculate the distances Le, Lf, and Lg from points E, F, and G to the theoretical datum plane respectively, and adjust the adjustable shims under the datum plane to be measured to make Le = Lf = Lg = H, then the measured datum plane can be determined to coincide with the theoretical datum plane, and the adjustment is completed.

[0027] The original datum point is a permanent datum point buried on the ground during civil engineering construction for the positioning of measuring instruments. When the total station is in a horizontal state, the vertical positioning axis of the total station passes through the original datum point; the backsight point of the total station is a permanent datum point buried at a convenient observation position during civil engineering construction. When the total station is in a horizontal state and its vertical positioning axis passes through the original datum point, the point used to determine the reference "0" plane of the total station when observing this point through the eyepiece of the total station; the observation point of the total station is the eyepiece of the total station.

[0030] (2) The present invention does not need to occupy the overhead crane in this bay of the continuous casting workshop where the segment basic frame is located for a long time, avoiding the serious problem of waste of resources.

Detailed implementation mode

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0046] Embodiment 1:

[0047] According to Figures 1-9 A high-efficiency installation measurement method for the sector segment basic frame of a heavy plate slab caster shown, includes the following steps.

[0048] Step 1: Use the total station 3 and the measuring and positioning device 1 for any spatial reference axis to measure and position the first measuring axis 5 on the sector segment basic frame 4.

[0049] Step 2: Use the total station 3 and the measuring and positioning device 1 for any spatial reference axis to measure and position the second measuring axis 6 placed on the sector segment basic frame 4.

[0050] Step 3: Use the total station 3 and the measuring and positioning device 2 for any spatial reference plane to test and adjust the installation reference plane on the sector segment basic frame 4.

[0051] Through the cooperation of the measuring and positioning device 1 for any spatial reference axis and the total station 3, accurate detection and positioning installation of the first measuring axis 5 and the second measuring axis 6 on the sector segment basic frame are realized. Through the cooperation of the measuring and positioning device for any spatial reference plane and the total station 3, detection, positioning and installation of the sector segment installation reference plane on the sector segment basic frame of the slab caster are realized.

[0052] In specific applications, the total station 3, the spatial arbitrary reference axis measurement and positioning device 1, and the spatial arbitrary reference plane measurement and positioning device 2 can also be connected to a computer to receive measurement data, calculate the data, calculate the deviation between the actual and theoretical absolute coordinate values of the measurement points, give the direction and adjustment amount that need to be adjusted for the reference axis or reference plane on the segment base frame of the slab caster, and quickly feedback the calculation results to the operator, thereby realizing the fast, efficient, and accurate positioning and adjustment of the installation reference of mechanical equipment.

[0053] Embodiment 2:

[0054] According to Figures 1-9 An efficient installation measurement method for the segment base frame of a heavy and wide slab caster shown, the difference from Embodiment 1 is that: the adopted spatial arbitrary reference axis measurement and positioning device 1 includes a first steel spherical prism 7, a sleeve 8, a distance measuring block 9, a sleeve cover plate 10, and a first strong magnet 11; the sleeve 8 is a hollow cylinder with one end open, and a magnet installation groove 18 is provided at the center position of its outer bottom surface, and a first strong magnet 11 is arranged in the magnet installation groove 18; the sleeve cover plate 10 is detachably connected to the outer side wall of the bottom surface of the sleeve 8, and the first strong magnet 11 is placed between the sleeve cover plate 10 and the sleeve 8; the first steel spherical prism 7 is adsorbed at the center position outside the sleeve cover plate 10; the distance measuring block 9 is placed in the sleeve 8 during measurement.

[0055] Furthermore, the sleeve 8 is an integral structure composed of two cylinders with different outer diameters; the inside of the cylinder with a larger outer diameter is hollow, and a magnet installation groove 18 matching the shape of the first strong magnet 11 is opened on the front end surface of the cylinder with a smaller outer diameter; the height of the first strong magnet 11 is the same as the height of the magnet installation groove 18; a thread matching the sleeve cover plate 10 is provided on the outer side wall of the cylinder with a smaller outer diameter; the distance measuring block 9 is a hollow cylinder, its outer diameter is smaller than the inner diameter of the sleeve 8, and its inner diameter is smaller than the diameter of the axis to be measured; the sleeve cover plate 10 is an integral structure composed of a ring and a flat cylinder; the flat cylinder is placed on the ring surface at one end of the ring, and the outer diameters of the ring and the flat cylinder are the same; the height of the ring is not greater than the length of the axis to be measured; a first prism installation groove 19 matching the first steel spherical prism 7 is opened at the center position of one surface of the flat cylinder, and a hole is opened at the center position of the groove bottom, so that the first steel spherical prism 7 is externally tangent to the first strong magnet 11 through this hole.

[0056] Further, the first prism mounting groove 19 is a spherical groove, the radius of the sphere being equal to the radius of the first steel spherical prism 7, and the center of the sphere being on the axial center line of the sleeve cover plate 10. The distance from the position of the center of the spherical groove to the surface of the first strong magnet 11 is equal to the radius of the first steel spherical prism 7. The sleeve cover plate 10 is made of a light material, such as hard aluminum alloy, and its outer side wall is provided with embossing or ribs to increase the friction and facilitate screwing.

[0057] In actual use, first place the distance measuring block 9 in the sleeve 8 and sleeve it on the base shaft to be measured. Then, adjust the angle of the first steel spherical prism 7 so that the center of the first steel spherical prism 7 is always within the observation area of the total station of the measuring instrument. Record the spatial relative coordinate values A(XA, YA, ZA) of the observation point at this moment with the observation point of the total station of the measuring instrument as the relative coordinate origin O(0, 0, 0), and use point A as the reference reference point, where the observation point is the center of the first steel spherical prism 7. After removing the distance measuring block 9 in the sleeve 8, then sleeve the sleeve 1 on the shaft to be measured and measure again, and record the spatial relative coordinate values B(XB, YB, ZB) of the observation point at this moment.

[0058] Based on the recorded relative coordinate values A(XA, YA, ZA) and B(XB, YB, ZB), calculate the deviation between the actual absolute coordinate value and the theoretical reference absolute coordinate value Z0(X0, Y0, Z0)) of the measurement point A, and the deviation between the center line of the detection axis, i.e., the line connecting A and B, and the center line of the theoretical reference axis:

[0059] When XA≠X0, YA≠Y0, ZA≠Z0, and |ZA - ZB|≠H, then the position and direction of the shaft to be measured need to be adjusted; where H is the thickness of the distance measuring block 9.

[0060] Repeat the above operations and re-measure the relative coordinate values of A and B.

[0061] When XA = X0, YA = Y0, ZA = Z0, and |ZA - ZB| = H; it is considered that the detected reference axis coincides with the theoretical reference axis, and the measurement is completed.

[0062] Finally, fix the shaft to be measured, and the detection, positioning, and installation of the spatial reference axis are completed.

[0063] The adoption of the above technical solution greatly improves the accuracy of measuring the spatial reference axis, greatly improves the work efficiency, saves the adjustment time cost and personnel cost, and reduces the labor intensity of the operator.

[0064] The setting of the distance measuring block in the present invention can quickly complete the recording of the measurement data of the same reference axis twice, improving the measurement efficiency.

[0065] In specific applications, the sleeve 8 is mainly used to quickly combine with the shaft to be measured and form a measuring point. Its inner diameter is the same as the outer diameter of the shaft to be measured, but a small gap is maintained. In order to be able to measure and position the shaft to be measured more accurately, the sleeve 8 is made of wear-resistant lightweight materials such as aluminum alloy. The first strong magnet 11 is fixed in the magnet mounting groove 18 at the top of the sleeve 8 through the sleeve cover 10. After the sleeve 8 is threadedly connected to the sleeve cover 10, the first strong magnet 11 is securely placed between the sleeve 8 and the sleeve cover 10. When the first strong magnet 11 is attracted to the first steel spherical prism 7, there will be no position movement, which ensures the accuracy of the measurement. The height of the first steel spherical prism 7 is the same as the height of the magnet mounting groove 18, which not only ensures the stable external tangent of the first strong magnet 11 and the first steel spherical prism 7, but also ensures that the measured parameter values ​​are stable and accurate.

[0066] In order to obtain the spatial relative coordinate values ​​of different observation points, the present invention adopts two methods: installing the distance gauge block 9 into the sleeve 8 and not installing the distance gauge block 9 into the sleeve 8 to measure two different coordinate values. The difference between the two measured values ​​is compared with the high value of the distance gauge block 9 to conveniently determine whether the position and direction of the axis to be measured need to be adjusted. The sleeve cover plate 10 is made of lightweight material, which can minimize the influence of the weight of the sleeve cover plate 10 on the measurement accuracy. Embossing is provided on the outer wall of the sleeve cover plate 10, which effectively increases the friction during screwing and fixing, and facilitates the assembly of the spatial arbitrary reference axis measurement and positioning device 1.

[0067] The first steel spherical prism 7 in this embodiment is a round spherical prism made of steel.

[0068] Embodiment three:

[0069] according to Figures 1-9An efficient installation measurement method for the segment basic frame of a heavy plate slab caster shown, which is different from the first embodiment in that: the spatial arbitrary reference plane measurement and positioning device 2 includes a base 12, a second steel spherical prism 17, two first cover plates 13, a second cover plate 15 and three second powerful magnets 14; the base 12 is a hollow cuboid structure, and a mounting plate 20 is horizontally arranged at the bottom of its outer side, and the cuboid and the mounting plate 20 are an integral structure; circular, shoulder-shaped first slot holes 21 and a plurality of first connection through holes 22 for connecting with the first cover plates 13 are respectively arranged on the outer surfaces of the upper and lower bottom surfaces of the base 12, and a second powerful magnet 14 is placed in each first slot hole 21; the two first cover plates 13 are respectively detachably connected to the upper and lower bottom surfaces of the base 12, and the second powerful magnets 14 arranged on the upper and lower bottom surfaces are respectively clamped between the first cover plates 13 and the base 12; the mounting plate 20 is a rectangular plate, a second slot hole 23 is opened at the center position thereof, a second powerful magnet 14 is placed in the second slot hole 23, the second cover plate 15 is detachably connected to the upper surface of the mounting plate 20, and a plurality of connection holes matching the second cover plate 15 are opened on the upper surface of the mounting plate 20, and the second cover plate 15 clamps the second powerful magnet 14 between the second cover plate 15 and the mounting plate 20; the second steel spherical prism 17 is placed on the second cover plate 15. Two of the second cover plates 15 are connected to the base 12 by screws 16, and the surfaces where the two second cover plates 15 are located are working surfaces and can be attached to the reference surface to be measured according to actual needs; for the convenience of connection, connection holes matching the first cover plates 13 are opened on the upper and lower surfaces of the base 12.

[0070] Furthermore, the depth of the first slot hole 21 is the same as the height of the second powerful magnet 14; the plurality of first connection through holes 22 are uniformly arranged around the first slot hole 21; the second cover plate 15 is a rectangular plate; a second prism mounting groove 24 for placing the second steel spherical prism 17 is opened at the center position of the upper surface of the rectangular plate, the second prism mounting groove 24 is a spherical surface groove, and the spherical surface of the spherical surface groove coincides with the spherical surface of the second steel spherical prism 17, and the center of the second steel spherical prism 17 is equidistant from the upper and lower bottom surfaces of the hollow cuboid in the base 12, so as to ensure the test accuracy; a through hole is provided at the bottom of the second prism mounting groove 24, so that after the second steel spherical prism 17 is placed in the second prism mounting groove 24 on the second cover plate 15, it can be stably adsorbed on the mounting plate 20 by magnetic force; a plurality of second connection through holes 25 for connecting with the mounting plate 20 are arranged around the second prism mounting groove 24, and the second cover plate 15 is connected to the mounting plate 20 by screws 16.

[0071] In actual use, first adsorb the spatial arbitrary reference plane measuring and positioning device 2 on the measured surface to be measured. The measured surface is a plane of the device to be installed, and the adjustment of this plane can be carried out through the adjustable shims under the device. If it is directly carried out on the civil engineering foundation, directly adjust the grouting shims. At this time, the distance from the center of the second steel spherical prism 17 to the measured surface is "H". Then, adjust the angle of the second steel spherical prism 17 so that the center of the second steel spherical prism 17 is always within the observation area of the total station. Taking the total station as the coordinate origin, establish a coordinate system, and then the spatial relative coordinate values of the observation points can be measured and recorded. At least 3 points A, B, and C (three points determine a plane) are detected on the plane to be detected, and the coordinate values of points A, B, and C are recorded. Taking the plane passing through the center of the second steel spherical prism 17 and parallel to the upper plane of the base 12 as the theoretical reference plane, calculate the distances La, Lb, and Lc from points A, B, and C to the theoretical reference plane, and adjust the adjustable shims under the measured surface to make La = Lb = Lc = H, then the coincidence of the measured surface and the theoretical reference plane can be determined. Fix the measured surface, and thus the determination and installation of the device reference plane are conveniently completed.

[0072] The adoption of this technical solution greatly improves the accuracy of measuring the spatial reference plane, improves work efficiency, greatly reduces errors, saves adjustment time and labor costs, and greatly reduces the labor intensity of workers.

[0073] The base 12 adopts a hollow cuboid structure, effectively reducing the self-weight of the spatial arbitrary reference plane measuring and positioning device 2 and improving its adsorption force. The base 12 is made of lightweight, wear-resistant and non-deformable materials, such as aluminum alloy, aluminum-magnesium alloy, titanium-magnesium alloy, etc. The depth of the first slot 21 is the same as the height of the second strong magnet 14, which can not only ensure the stability of the strong magnet 3, but also improve the adsorption force of the strong magnet 3.

[0074] The size of the first cover plate 13 matches the sizes of the upper and lower surfaces of the base 12, and the size of the second cover plate 15 matches the size of the upper surface of the rack plate 20. This not only facilitates the measurement operation, but also avoids waste caused by excessive size.

[0075] After the base 12 is adsorbed on the measured surface, place the second steel spherical prism 17 on the second prism mounting groove 24 at the center position of the second cover plate 15. The second steel spherical prism 17 can be stably adsorbed on the mounting plate 20, and then subsequent measurement operations can be carried out, which is simple and convenient. The radius of the second prism mounting groove 24 for placing the second steel spherical prism 17 on the second cover plate 15 is designed to be equal to the radius of the second steel spherical prism 17. The surface distance from the position of the center of the sphere of the second prism mounting groove 24 to the surface of the second strong magnet 14 at the mounting plate 20 is equal to the radius of the second steel spherical prism 17. That is, after the second steel spherical prism 17 is placed in the second prism mounting groove 24, the second steel spherical prism 17 is externally tangent to the second strong magnet 14 at this place. The second cover plate 15 is in the form of a through hole provided at the bottom of the groove, which not only ensures the close fit between the second steel spherical prism 17 and the second prism mounting groove 24, but also makes the second steel spherical prism 17 stably placed on the second strong magnet 14, avoiding damage to the second steel spherical prism 17 due to human error.

[0076] The second steel spherical prism 17 in this embodiment is a steel spherical prism.

[0077] Embodiment 4:

[0078] According to Figures 1-9 A high-efficiency installation measurement method for the segment basic frame of a heavy plate continuous caster shown, which is different from Embodiment 1 in that: for the measurement and positioning of the first measurement axis 5 on the segment basic frame 4 in the first step, the following method can be adopted:

[0079] The first step: Adjust the position of the total station 3 so that the plane P1 formed by the original reference point, the backsight point of the total station and the observation point of the total station is parallel to the preset center plane P0 of the continuous caster. After parallelism, position the total station 3;

[0080] The second step: Take the total station 3 as the coordinate origin, the horizontal direction perpendicular to the center plane of the continuous caster and facing the center plane of the continuous caster from the first measurement axis 5 as the positive X-axis direction, the vertical upward direction as the positive Z-axis direction, and the horizontal direction facing the civil construction foundation as the positive Y-axis direction to establish a coordinate system;

[0081] Step 3: Sleeve the sleeve 8 in the arbitrary spatial reference axis measuring and positioning device 1 onto the first measuring axis 5 on the segment base frame 4; record the central coordinates A(Xa, Ya, Za) of the first steel spherical prism 7 in the arbitrary spatial reference axis measuring and positioning device 1 with the total station 3; then place the fixed-distance gauge 9 in the sleeve 8 and sleeve it onto the first measuring axis 5 on the segment base frame 4, and then record the central coordinates B(Xb, Yb, Zb) of the first steel spherical prism 7 in the arbitrary spatial reference axis measuring and positioning device 1 at this time with the total station 3, calculate the distance between AB, and when |AB| = |Za - Zb|, it is determined that the line connecting points A and B is perpendicular to the plane P0; at this time, initially position the segment base frame along the Z-axis;

[0082] Step 4: Move the segment base frame 4 along the Z-axis, continue to measure the central coordinates A(Xa, Ya, Za) of the first steel spherical prism 7, calculate the actual distance from point A to the P0 plane, and when the actual value is equal to the theoretical value, position the Z-axis;

[0083] Step 5: Move the segment base frame 4 along the Y-axis, continue to measure the central coordinates A(Xa, Ya, Za) of the first steel spherical prism 7, calculate the actual distance from point A to the P0 plane, and when the actual value is equal to the theoretical value, position the Y-axis;

[0084] Step 6: Move the segment base frame 4 along the X-axis, continue to measure the central coordinates A(Xa, Ya, Za) of the first steel spherical prism 7, calculate the actual distance from point A to the P0 plane, and when the actual value is equal to the theoretical value, position the X-axis.

[0085] The method for measuring and positioning the second measuring axis 6 placed on the segment base frame 4 in Step 2 can be as follows: Sleeve the sleeve 8 onto the second measuring axis 6 of the segment base frame 4 to be detected, and with the first measuring axis 5 adjusted in Step 1 as the center, rotate the segment base frame 4, and measure the central coordinates C(Xc, Yc, Zc) of the first steel spherical prism 7 at this time. After the absolute coordinate value of point C is equal to the theoretical value, fix the segment base frame 4.

[0086] The method for testing and adjusting the installation reference plane on the segment base frame 4 in Step 3 is specifically as follows:

[0087] Step 1: Adjust the position of the total station 3 so that the plane P1 formed by the original reference point, the backsight point of the total station, and the observation point of the total station is parallel to the preset continuous casting machine center plane P0, and then position the total station 3;

[0088] Step 2: Place the spatial arbitrary reference plane measuring and positioning device 2 on the equipment installation reference plane of the segment base frame 4 to be installed. At this time, the distance from the center of the second steel spherical prism 17 on the spatial arbitrary reference plane measuring and positioning device 2 to the reference plane to be measured is “H”. Observe the center of the second steel spherical prism 17 through the total station 3, record the relative coordinates x and y of the observation point, and calculate the deviation between the actual value and the theoretical value of the distance from the center of the second steel spherical prism 17 to the reference plane to be measured;

[0089] Step 3: Arbitrarily select at least 3 additional detection points on the reference plane to be measured, and record the coordinates of the second spherical prism 17 corresponding to the three points: E(Xe, Ye, Ze), F(Xf, Yf, Zf), G(Xg, Yg, Zg); calculate the distances Le, Lf, and Lg from points E, F, and G to the theoretical reference plane respectively, and adjust the adjustable shims below the reference plane to be measured to make Le = Lf = Lg = H, then the measured reference plane can be determined to coincide with the theoretical reference plane, and the adjustment is completed.

[0090] The original reference points used in the above method are permanent reference points buried in the ground during civil construction for the positioning of surveying instruments. When the total station is in a horizontal state, the vertical positioning axis of the total station passes through the original reference point; the backsight point of the total station is a permanent reference point buried during the construction of the civil construction foundation for easy observation. When the total station is in a horizontal state and its vertical positioning axis passes through the original reference point, the point used to determine the reference “0” plane of the total station when observing this point through the eyepiece of the total station; the observation point of the total station is the eyepiece of the total station.

[0091] Adopting the technical solution of the present invention, the cumulative error is small and the accuracy is high in the measurement, adjustment and installation of the segment base frame in the slab caster. The measurement accuracy can reach 0.001 mm. When using the present invention for the measurement, positioning and installation of the segment base frame of the slab caster, it is not necessary to occupy the overhead crane in this bay of the workshop for a long time, avoiding the serious problem of waste of resources. And only 3 people are needed in the operation process, and the task can be completed in about 3 days, greatly shortening the installation time of the segment base frame in the slab caster and saving manpower.

[0092] Adopting the technical solution of the present invention reduces the restriction of site limitation factors. Especially during the installation and construction of the segment base frame of the heavy plate slab caster, there are many site limitation factors and it is not easy to measure the position. Through the present invention, by extending the working range of the measuring instrument, the point (or plane) to be measured is extended to a position where it can be observed, greatly improving the work efficiency, greatly reducing the error, reducing the labor intensity of workers, and saving social resources and costs.

[0093] In the case of no conflict, those skilled in the art may, according to the actual situation, combine the relevant technical features in the above examples with each other to achieve corresponding technical effects. Specific combinations will not be elaborated one by one here.
