Multiple sets of positioning slide rails 4 are set on the mounting base 1, and a set of sliding movable parts 5 and a set of fixed movable parts 5 are mounted on the positioning slide rails 4. The sliding movable parts 5 have threaded sleeves 6 inside that cooperate with the threaded rods 3. This design ensures that the heat exchanger body... It can be quickly plugged and unplugged into the positioning slot on the moving part 5, while increasing the adaptability of the device to heat exchangers of different sizes and models, greatly facilitating daily maintenance. The drive component is set inside the fixing slot of the mounting base 1 and is used to provide rotational power for the threaded rod 3. This design avoids the inconvenience of manually rotating the threaded rod 3, further improving the ease of operation and work efficiency. The setting of the positioning component increases the stability of the connection position between the heat exchanger and the moving part 5, increases the ease of disassembly and assembly of the heat exchanger and the moving part 5, improves the ease of disassembly and assembly, and reduces maintenance procedures.

[0019] like Figures 1 to 4As shown, in a preferred embodiment, the drive assembly includes a drive motor 7 disposed inside the fixing groove of the mounting base 1. A drive gear 8 is coaxially mounted on the output end of the drive motor 7, and a driven gear 9 is coaxially mounted on the threaded rod 3. The driven gear 9 meshes with the drive gear 8 for transmission. An isolation member 10 is provided on a set of fixing members 2, with the drive gear 8 and driven gear 9 positioned within the inner groove of the isolation member 10. By placing the drive motor 7 inside the fixing groove of the mounting base 1, the rotation of the threaded rod 3 is automatically controlled, avoiding the inconvenience of traditional manual tightening and significantly improving work efficiency and ease of operation.

The display device 19 is mounted on the fixed part 2, so that the operator can intuitively see the data measured by the laser rangefinder 18, which facilitates the monitoring of the position of the movable part 5 and improves the visibility and controllability of the operation.

[0025] like Figures 1 to 4 As shown, the preferred solution operates as follows: Place the tubular heat exchanger clamping and fixing device in the predetermined working position. Adjust the device to a horizontal state using the adjusting feet 17 at the bottom of the mounting base 1 to ensure stability during use. Turn on the drive motor 7 in the drive assembly. Through the meshing of the drive gear 8 and the driven gear 9, the threaded rod 3 is driven to rotate. At this time, the threaded sleeve 6 slides along the positioning slide rail 4, and the moving part 5 begins to move until it reaches the predetermined position. Observe the data on the display device 19. Monitor the position change of the moving part 5 in real time through the laser rangefinder 18 to ensure that it accurately reaches the set position. Align the heat exchanger body to be installed with the positioning groove on the moving part 5 and gently push it in. The positioning arc groove and buffer pad 16 on the moving part 5 can ensure that the heat exchanger body is accurately positioned and protected during insertion. When the heat exchanger body is fully inserted, the positioning pin 13 automatically inserts into the positioning hole on the heat exchanger body under the action of the spring 14 to achieve automatic positioning.

[0026] The present invention relates to a tubular heat exchanger clamping and fixing device. Its installation method, connection method or setting method are all common mechanical methods. As long as it can achieve its beneficial effect, it can be implemented.

[0027] The above description is only a preferred embodiment of the present utility model.
