Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steam turbine maintenance, in particular to an I-type plate seat frame of a laser mapping and tracking instrument. Background Art
[0002] For the installation process of large steam turbine bodies, centering of the bulkhead of the turbine body is a very important task. It is directly related to the subsequent steam seal clearance adjustment work. If the concentricity of the bulkhead is not good, it will greatly increase the workload of the steam seal clearance adjustment work and affect the uniformity of the steam seal clearance, thereby affecting the economy, stability and safety of the unit during operation. Among them, making each dynamic and static clearance of the steam turbine reach the optimal state is of great significance to improving the stability and thermal efficiency of the unit. In traditional construction technology, the methods mostly used for centering the bulkhead are mainly the wire drawing method and the false shaft method, which require a lot of labor and the accuracy of the centering of the bulkhead is low.
[0003] Due to the limited operating space on the turbine cylinder platform, there is not enough horizontal surface to set up the laser tracker. Setting it up too far can easily lead to errors in the measurement results. It may also cause the laser tracker to rotate unsteadily or be blocked by terrain objects when tracking the signal of the target ball or target gun, so that the laser tracker needs to change the measurement point multiple times and measure at different positions, which may lead to errors in the measurement data. In addition, when the laser tracker changes its position on the turbine cylinder for transfer, there will be not only measurement errors, but also a certain risk of damage to the laser tracker during transportation. Utility Model Content
[0004] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art and to provide a laser mapping tracker I-plate mount that can solve the problem of measuring at different positions, which may lead to errors in the measurement data. In addition, when the laser tracker is repositioned on the turbine cylinder for transfer, there is not only a measurement error, but also a certain risk of damage to the laser mapper during transportation.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a laser mapping tracker I-plate mount, comprising a base plate and a laser mapping instrument mounting frame; the laser mapping instrument mounting frame comprises two side plates, four support plates, two frame plates, four support oblique rods, a disc base, four first bolts, a support frame and a laser tracker, the two side plates are fixedly connected to the top of the base plate, the four support plates are fixedly mounted on the left and right sides of the top of the base plate respectively, the two frame plates are fixedly connected to the top of the two side plates respectively, the lower ends of the four support oblique rods are fixedly mounted on the surfaces of the left and right side plates respectively, the upper ends of the four support oblique rods are fixedly mounted on the surfaces of the left and right frame plates respectively, the disc base is fixedly mounted on the top of the base plate, the four first bolts are equidistantly mounted in a circle inside the disc base, the surface of the base plate is equidistantly provided with four first bolt slots, and the lower ends of the four first bolts are threadedly connected to the inside of the four first bolt slots respectively.

[0023] See also Figure 1-4The utility model provides a technical solution: a laser mapping tracker I-type plate mount, including a base plate 1 and a laser mapping instrument mounting frame, the laser mapping instrument mounting frame includes two side plates 2, four support plates 3, two frame plates 4, four support diagonal rods 5, a disc base 6, four first bolts 7, a support frame 9 and a laser tracker 10, the two side plates 2 are fixedly connected to the top of the base plate 1, the four support plates 3 are fixedly installed on the left and right sides of the top of the base plate 1, the two frame plates 4 are fixedly connected to the top of the two side plates 2, the bottom of the four support diagonal rods 5 The ends are respectively fixedly mounted on the surfaces of the left and right side panels 2, the upper ends of the four supporting oblique rods 5 are respectively fixedly mounted on the surfaces of the left and right side panels 4, the disc base 6 is fixedly mounted on the top of the base plate 1, and four first bolts 7 are equidistantly mounted in a circular shape inside the disc base 6. The surface of the base plate 1 is equidistantly provided with four first bolt slots 8 in a circular shape, and the lower ends of the four first bolts 7 are respectively threadedly connected to the inside of the four first bolt slots 8. The lower end of the support frame 9 is fixedly connected to the top of the disc base 6, and the laser tracker 10 is fixedly mounted on the upper end of the support frame 9.
[0024] After the staff places the disc base 6 on the top of the base plate 1, the staff can use a wrench to rotate the four first bolts 7 and make them enter the four first bolt slots 8 to install and fix the disc base 6. The four first bolts 7 can be used to fix the disc base 6 in the center of the base plate 1, and the laser tracker 10 can be fixed in the center of the base plate 1.
[0025] A bearing box 11 is provided on the outside of the base plate 1, and a second bolt slot 12 is provided on the top of the bearing box 11. The tops of the two frame plates 4 are fixedly connected with matching pressure plates 13. The surfaces of the two matching pressure plates 13 are provided with waist-shaped holes 14. Two second bolts 15 are slidably installed inside the two waist-shaped holes 14, and the lower ends of the second bolts 15 are threadedly connected to the inside of the second bolt slot 12.
[0026] Finally, the staff puts the two frame plates 4 on the top of the bearing box 11 and places the frame plates 4 in the middle of the two second bolt slots 12 on the front and rear sides. Then, the staff can use a wrench to rotate the two second bolts 15 and make them go into the inside of the two second bolt slots 12. After the two second bolts 15 are fixedly installed in the inside of the two second bolt slots 12, the frame plates 4 can be fixedly installed on the top of the bearing box 11 by squeezing the waist-shaped holes 14. The staff can fix the other frame plate 4 on the top of the bearing box 11 in the same way. Since the two matching pressure plates 13 are at the same position from the laser tracker 10, the staff can fix the laser tracker 10 in the middle position of the bearing box 11 in this way. Furthermore, when the I-plate frame is in use, the four supporting diagonal rods 5 are located at the junction of the frame plate 4 and the side plate 2, and are fixed with bolts in a triangular structure to prevent the I-plate frame from deformation. The I-plate frame can be installed in the bearing box 11, stably fixing the laser tracker 10 so that the laser tracker 10 is installed on the centerline of the turbine. This effectively solves the problem of the laser tracker being blocked by objects on site when tracking the target ball or target gun during turbine maintenance due to limited space on the cylinder body, and requiring multiple transfers during turbine maintenance. The I-plate frame is located in the bearing box 11, placing the laser tracker 10 on the centerline of the turbine. This not only improves the accuracy of laser measurement, but also reduces the number of times the laser tracker 10 needs to be moved, thereby reducing the risk of damage to the precision instrument during transportation. This shortens the time required for laser measurement of turbine centering and improves maintenance efficiency.
[0027] Working principle: For the laser mapping tracker I-plate mount, after the staff places the disc base 6 on the top of the base plate 1, the staff can use a wrench to rotate the four first bolts 7 and insert them into the four first bolt slots 8 to install and fix the disc base 6, and then the laser tracker 10 can be fixedly installed in the center position of the base plate 1. After the staff sets up the two frame plates 4 on the top of the bearing box 11, the frame plates 4 are placed in the middle position of the two second bolt slots 12 on the front and rear sides. Then, the staff can use a wrench to rotate the two second bolts 15 and insert them into the two second bolt slots 12. After the two second bolts 15 are fixedly installed in the two second bolt slots 12, the frame plates 4 can be fixedly installed on the top of the bearing box 11 by squeezing the waist-shaped holes 14. In this way, the laser tracker 10 can be fixedly installed in the middle position of the bearing box 11, so that the laser tracker 10 is set on the center line of the steam turbine, which effectively solves the problem of the laser tracker being blocked by objects on site when tracking the target ball or target gun during steam turbine maintenance due to limited space on the cylinder body.
[0028] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
