[0026] Referring to Figure 1 and Figure 7 A plate heat exchanger upper guide rod structure, including flexible beam 1, flexible beam 1 lower end is installed with suspension support 2, and the lower edge position of flexible beam 1 is provided with a plurality of first positioning grooves 4, and the position of first positioning groove 4 is provided with the first sunken groove 5 with the opening upwards, and the upper edge position of suspension support 2 is provided with a plurality of second positioning grooves 6, and the position of second positioning groove 6 is provided with the second sunken groove 7 with the opening downwards, and positioning assembly 3 is clamped and installed in first positioning groove 4 and second positioning groove 6;

[0027] Positioning assembly 3 includes upper positioning plate 301 located above first sunken groove 5, and fixed block 302 is fixed to the lower surface of upper positioning plate 301, and lifting block 303 is slidably arranged at the lower end of fixed block 302, and lower positioning plate 304 is fixed to the lower end of lifting block 303, and lower positioning plate 304 is located below second sunken groove 7, and adjusting bolt 305 is rotatably connected to the middle part of upper positioning plate 301, and adjusting bolt 305 is screw-connected with lifting block 303.

[0028] The contact position of flexible beam 1 and suspension support 2 is provided with a plurality of bolt holes 8.

[0029] In the embodiment, when assembling the upper guide rod structure of the application, first, the flexible beam 1 and the suspension support 2 are preliminarily aligned so that the first positioning groove 4 and the second positioning groove 6 coincide with each other, then the positioning assembly 3 is passed through the first positioning groove 4 and the second positioning groove 6 so that the upper positioning plate 301 of the positioning assembly 3 is located above the first sunken groove 5 and the lower positioning plate 304 is located below the second sunken groove 7, then the adjusting bolt 305 is rotated so that the lifting block 303 threadedly connected with the adjusting bolt 305 moves upward, thereby promoting the upper positioning plate 301 and the lower positioning plate 304 to approach each other and be clamped into the first sunken groove 5 and the second sunken groove 7 respectively, the flexible beam 1 and the suspension support 2 are preliminarily fixed by the positioning assemblies 3, then drilling equipment is used to drill the surfaces of the flexible beam 1 and the suspension support 2 from bottom to top to ensure the drilling stability and precision of the bolt holes 8, finally, the flexible beam 1 and the suspension support 2 are finally fixed by using bolts to pass through the bolt holes 8, thereby replacing the traditional welding fixation with bolt fixation, reducing the fixation difficulty and making the disassembly and assembly more convenient and facilitating subsequent replacement of different types of suspension supports 2.
