The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0057] like Figures 1 to 7As shown, the present invention provides a method for inserting a multi-piece frame assembly of a hot isostatic press into a walking device, which is used to movably install N-piece frames 30 on a guide rail 10 through a walking device 20, where N is a positive integer. The method includes the following steps:

[0058] Step S1: arranging a set of guide rails 10 in a horizontal direction on a guide rail installation surface and fixing the guide rails 10;

[0059] Step S2: installing the running device 20 on the guide rail 10, and adjusting the parallelism between the plurality of mounting surfaces 23 on the running device 20 and the plane of the guide rail 10 to be within a first error assessment range;

[0060] Step S3: Install N frames one by one on the mounting surfaces 23 of the walking device 20, and adjust the parallelism between the frames 30 and the verticality between the frames 30 and the plane of the guide rail 10 to within the second error assessment range.

[0061] The method for inserting a multi-piece frame assembly of a hot isostatic press into a walking device of the present invention is relatively convenient for on-site installation and simple to operate, and can solve the problems of inaccurate manual measurement values ​​and unsafe operation.

[0062] The method for inserting a multi-piece frame assembly of a hot isostatic press into a walking device of the present invention uses auxiliary equipment at a low cost during operation, thereby achieving the purpose of reducing costs and increasing efficiency.

[0063] The specific operation process of each step of the method for inserting a multi-piece frame assembly of a hot isostatic press into a walking device of the present invention will be described in detail below.

[0064] In step S1, a set of guide rails 10 are installed and fixed. A set of guide rails 10 includes two guide rails 10 arranged in parallel and parallel to each other. During the installation of the guide rails 10, the horizontality of the plane on the guide rails 10 needs to be ensured. The specific installation and fixing process includes the following steps:

[0065] Step S11: embed anchor bolts on the guide rail installation surface (usually the ground). The anchor bolts are fixed by grouting (concrete) once, and the lower ends of multiple anchor bolts are fixed on the guide rail installation surface by grouting once along the length direction of the guide rail 10.

[0066] Step S12: After the anchor bolts are fixed, the guide rail 10 is placed on the anchor bolts and leveled to ensure the horizontality of the plane on the guide rail 10 .

[0067] Step S13: After the parallelism of the plane on the guide rail 10 meets the requirement, the guide rail 10 is fixed on the anchor bolts and grouting is performed to further fix the guide rail 10. The further fixation of the guide rail 10 is achieved by secondary grouting (concrete).

[0068] Further, such as Figure 2 As shown, the leveling process of the guide rail 10 includes the following steps:

[0069] Step S121: placing a plurality of level meters on the guide rail 10 along the length direction of the guide rail 10;

[0070] Step S122: Using the line connecting the contact surfaces at the head and tail ends of the guide rail 10 as the horizontal reference, using the error curve correction method, draw an error curve according to the readings of each level meter, such as Figure 2 Specifically, at each test point, the 0° readings △1 and △2 of the level and the 180° readings △3 and △4 of the level are read, and the average value (△1+△2+△3+△4) / 4 is calculated as the error data of each test point (at the level), and the error curve is drawn according to the above error data.

[0071] Step S123: The position of the guide rail 10 is changed by adjusting the adjustment mechanism on the guide rail 10, such as Figure 2 As shown, until the error curve is fitted within the range of the error assessment baseline, that is, the error curve is between the positive allowable error line and the negative allowable error line.

[0072] In step S2, the running device 20 is installed and the parallelism is adjusted, such as Figure 3 and Figure 4 As shown, the traveling device 20 is a mobile trolley, which includes a frame 21 and traveling wheels 22. The frame 21 is formed with a mounting surface 23. Each frame 30 is mounted on the frame 21. The traveling wheels 22 are arranged at the lower end of the frame 21. The traveling wheels 22 are mounted on the guide rail 10 and can roll along the guide rail 10. The installation process only requires the mobile trolley to be placed on the guide rail 10 accordingly, but the parallelism between the mounting surface 23 on the frame 21 and the plane of the guide rail 10 needs to be ensured. The specific adjustment process of the parallelism includes the following steps:

[0073] Step S21: Figure 4 and Figure 5 As shown, the spatial coordinates of at least three position points are collected on each installation surface 23; in this embodiment, the spatial coordinates of three different position points (respectively a first position point 231, a second position point 232 and a third position point 233) are collected on each installation surface 23.

[0074] Step S22: plane fitting is performed on all position points collected on all mounting surfaces 23 to form a fitting plane. The fitting method is as follows: Figure 8 As shown, the coordinates of the position points collected on all the installation surfaces 23 are screened for qualified Z coordinate points according to the flatness requirements, and all the qualified Z coordinate points are plane-fitted to finally form a fitting plane that meets the installation requirements.

[0075] Step S23: Adjust the position of the fitting plane by adjusting the tooling on the walking device 20 until the parallelism between the fitting plane and the plane of the guide rail 10 is within the second error assessment range; the tooling may be adjustment screws provided on the walking device 20 for adjusting each mounting surface 23 .

[0076] Further, such as Figure 4 As shown, the frame 30 is fixed to the walking device 20 by overlapping the bosses set in the thickness direction, so four mounting surfaces 23 are provided on the walking device 20 corresponding to each frame 30, and there are 4N mounting surfaces 23 on the walking device 20; in this embodiment, there are 12 mounting surfaces 23 on the walking device 20.

[0077] In step S3, multiple frames 30 are installed and parallelism and verticality are adjusted. In this embodiment, the number N of frames 30 is 3. The three frames 30 are lifted and turned over one by one by a multi-degree-of-freedom lifting device until all are installed on the walking device 20. After installation, parallelism and verticality are adjusted. The specific adjustment process includes the following steps:

[0078] Step S31: Figure 6 and Figure 7 As shown, a first laser emitter 40 and a first laser receiver 41 are respectively installed at upper and lower opposite positions on the side of each frame 30 to obtain the numerical signal corresponding to each frame 30 and convert it into a first straight line signal in the space coordinate system. Each frame 30 corresponds to a first straight line signal;

[0079] Step S32: along the length direction of the guide rail 10, a second laser transmitter 42 and a second laser receiver 43 are installed at intervals on the plane of the guide rail 10 to obtain a numerical signal corresponding to the contact surface of the guide rail and convert it into a second linear signal in the spatial coordinate system;

[0080] Step S33: Fine-tune the position of each frame 30 by fine-tuning the nut until the parallelism between the first straight line signals is within the second error assessment range, and the verticality between the first straight line signal and the second straight line signal is within the second error assessment range, that is, adjust until the parallelism between the frames 30 meets the requirements and the verticality between the frame 30 and the plane of the guide rail 10 meets the requirements.

[0081] During the parallelism and verticality adjustment process, the photoelectric signals are converted into numerical signals for observation and evaluation, which can ensure higher adjustment accuracy.

[0082] According to one embodiment of the present invention, the number N of frames 30 installed on the walking device 20 is 3, 4 or 5.

[0083] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
