[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] For reference as follows Figures 1-5 The present invention will be described as follows:

[0034] Example: A crossbeam track structure on a plate heat exchanger. From the perspective of structural composition, the crossbeam track structure consists of a crossbeam part 1, a track part 2, a connecting part 3, a base plate 4, and a cover plate 5.

[0035] The crossbeam 1 is long and narrow, and its vertical cross-section is a U-shaped structure with an opening facing downwards. This structural form provides a guiding foundation for the sliding of the movable clamping plate.

[0036] The lower end of the crossbeam 1 bends outward to extend a track 2 perpendicular to it. The track 2 is a long strip structure set along the length of the crossbeam 1. As the direct contact surface for the sliding of the moving clamping plate, its structural shape directly affects the stability of the sliding process.

[0037] The outer edge of track section 2 bends downward to form a connecting section 3 perpendicular to it. Connecting section 3 is a long strip structure set along the length of crossbeam section 1. Connecting section 3 mainly serves to connect track section 2 and base plate 4.

[0038] The crossbeam 1, track 2, and connecting part 3 are set as a single unit.

[0039] In terms of manufacturing process, the crossbeam 1, track 2, and connecting part 3 are integrally formed from a single piece of metal sheet through bending. This manufacturing method has multiple advantages: First, the operation process is simple, eliminating the need for separate processing and pre-positioning of multiple components; the three parts can be formed simply through a pre-defined bending process, significantly reducing processing steps. Second, processing efficiency is significantly improved; compared to the traditional method of processing multiple components separately and then assembling them, integral bending processing can shorten working time and increase product output per unit time. Third, manufacturing costs are reduced, saving the costs of equipment debugging and material cutting required for processing multiple components separately, while also reducing rework costs caused by misalignment between components. In addition, the integrally formed structure eliminates the connection gaps between the crossbeam 1, track 2, and connecting part 3, resulting in more direct and uniform force transmission, stronger structural stability, and better ability to withstand the loads generated during the sliding of the moving clamp.

[0040] It also includes a base plate 4 positioned between the two connecting parts 3, with its two sides welded to the two connecting parts 3 respectively. This further improves the overall structure. The two originally relatively independent connecting parts 3 are laterally connected by the base plate 4, enhancing the lateral stiffness of the structure and preventing lateral deformation of the track section under stress.

[0041] Cover plates 5 are provided at both ends of the crossbeam section 1 along its length. The edges of the cover plates 5 are welded to the crossbeam section 1, the track section 2, the connecting section 3, and the base plate 4, thus sealing the ends of the entire structure. This design prevents external dust and impurities from entering the structure. The welded connections of the cover plates 5 with each part form a closed integral structure, making the connections between components more robust and further improving the torsional resistance and load-bearing capacity of the overall structure.

[0042] In summary, this beam track structure, through reasonable structural design and optimized processing technology, achieves the characteristics of simple processing, high efficiency, and low cost, while ensuring the overall stability of the structure and meeting the requirements of plate heat exchangers for beam tracks.

[0043] The cover plate 5 is provided with two threaded connection holes 6, spaced vertically apart. These holes allow for a secure connection between the entire crossbeam track and the equipment frame. The threaded connection facilitates installation and disassembly of the crossbeam track, simplifying future maintenance and replacement. The two spaced-apart connection holes 6 ensure a more rational distribution of connection points, preventing uneven stress that might occur with single-point connections, ensuring the stability of the connection between the crossbeam track and the equipment frame, and preventing relative displacement during operation.

[0044] The inner side of the cover plate 5 is provided with an annular connecting ring 7, which fits and connects with the space enclosed by the crossbeam part 1, the track part 2, the connecting part 3, and the base plate 4. The connecting ring 7 can increase the contact area between the cover plate 5 and the crossbeam part 1, the track part 2, the connecting part 3, and the base plate 4, thereby enhancing the stability of the connection.

[0045] The outer contour of the cover plate 5 corresponds to the outer contour of the shape formed by the crossbeam part 1, the track part 2, the connecting part 3, and the base plate 4.

[0046] The connection between track section 2 and connecting section 3 is curved. This design effectively disperses stress concentration at the connection point, preventing localized deformation or cracking caused by stress concentration under the load of the sliding clamp, thus extending the service life of the track structure. Simultaneously, the curved transition reduces machining dead angles that may result from right-angle connections, facilitating subsequent processing such as grinding during manufacturing, ensuring the smoothness of the structural surface, and reducing resistance to the sliding of the clamp.

[0047] In terms of processing technology, the crossbeam part 1, the track part 2, and the connecting part 3 are formed by bending a single piece of metal sheet, and the thickness of the metal sheet used is 2-5mm.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
