[0029] 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.

[0030] For reference as follows Figures 1-8 The present invention will be described as follows:

[0031] Example: A plate heat exchanger clamp pulley structure, including a fixed block 4 and rollers 3.

[0032] A fixing plate 5 is provided on the front end face of the fixing block 4, and the fixing block 4 and the fixing plate 5 are set perpendicularly. As a basic connecting component, the fixing block 4 has the fixing plate 5 set perpendicularly on its front end face. This vertical setting provides a stable connection foundation for the subsequent structure.

[0033] The lower end of the fixing plate 5 is square, the upper end of the fixing plate 5 is semi-circular, and the fixing block 4 is connected to the lower end of the fixing plate 5.

[0034] The edge of the fixing plate 5 extends forward to form a cover 6. The cover 6 has openings facing the front and the bottom. This opening design not only leaves the necessary space for the installation and operation of the roller 3, but also forms a protective barrier for the roller 3 from the top and the rear, effectively blocking dust, impurities and other foreign objects from entering from the top and the rear, reducing the damage of foreign objects to the roller 3.

[0035] A connecting shaft 7 is provided on the front side of the fixing plate 5, and a roller 3 is rotatably connected to the connecting shaft 7. The roller 3 is located inside the cover 6. This installation method allows the roller 3 to be effectively enclosed inside the cover 6, which greatly reduces the direct contact between the roller 3 and the external environment compared to the traditional exposed design.

[0036] It also includes a clamping plate 1, with a connecting groove 8 at the upper end of the clamping plate 1, a long connecting beam 2 inside the connecting groove 8, and slide rails 11 on both sides of the lower end of the connecting beam 2. The fixing block 4 is fixedly connected to the clamping plate 1 on both sides of the connecting groove 8, and the roller 3 is slidably connected to the slide rail 11.

[0037] The roller 3 is slidably connected to the slide rails 11 on both sides of the lower end of the connecting beam 2. The connecting groove 8 at the upper end of the clamping plate 1 is used to connect with the connecting beam 2. The fixing block 4 is fixedly connected to the clamping plate 1 on both sides of the connecting groove 8. When the clamping plate 1 moves, the roller 3 rolls along the slide rail 11, realizing the smooth movement of the clamping plate 1 on the connecting beam 2. Moreover, since the roller 3 is protected by the cover 6, the rolling process is more stable and less affected by external interference.

[0038] Compared with existing technologies, the biggest improvement of this structure lies in placing the rollers 3 inside the cover 6. This design fundamentally solves the problem of the rollers 3 being exposed and susceptible to environmental influences. On the one hand, it prevents dust and impurities from adhering to the surface of the rollers 3, reducing the frictional resistance between the rollers 3 and the slide rail 11, and ensuring the efficient movement of the clamping plate 1. On the other hand, in harsh environments, such as high temperature, high humidity, or environments with corrosive gases, the cover 6 can provide protection for the rollers 3, slowing down the aging and damage rate of the rollers 3, extending their service life, thereby improving the stability and reliability of the entire plate heat exchanger clamping plate pulley structure, reducing equipment maintenance costs and frequency, and ensuring the continuous and stable operation of the plate heat exchanger.

[0039] The connecting shaft 7 is coaxially positioned with the upper semi-circular end of the fixing plate 5. This precise positioning ensures that the roller 3 maintains a stable, centrally symmetrical state after installation. When the roller 3 rotates around the coaxially positioned connecting shaft 7, the force is more evenly distributed, avoiding abnormal wear and shaking caused by eccentricity, and ensuring the smoothness of the roller 3 during rolling.

[0040] The front end of the connecting shaft 7 is flush with the front end of the cover 6. This allows for a reasonable planning of the installation space for the roller 3 within the cover 6, ensuring that the roller 3 can roll smoothly while making full use of the protective space of the cover 6. This prevents damage from external collisions caused by the connecting shaft 7 being too long and protruding, and also avoids instability in the installation of the roller 3 due to it being too short.

[0041] The fixing block 4 is elongated and has elongated connecting grooves 8 running through its upper and lower sides. These connecting grooves 8 provide a channel for connecting the fixing block 4 and the clamping plate 1. The elongated connecting grooves 8 have a certain amount of adjustment space during installation, allowing the fixing block 4 and the clamping plate 1 to be finely adjusted within a certain range, which facilitates alignment and calibration during installation.

[0042] The upper side of the fixing block 4 is provided with a receiving groove 9 corresponding to the connecting groove 8, and the width of the receiving groove 9 is greater than the width of the connecting groove 8. This design is specifically for bolt connections. When the fixing block 4 is fixed to the clamping plate 1 with bolts, after the bolt passes through the connecting groove 8, the screw head can be embedded in the receiving groove 9, which limits and conceals the screw head. On the one hand, this makes the bolt connection more stable and prevents the screw head from loosening or shifting due to external force or impact during use; on the other hand, the concealed screw head design makes the upper surface of the fixing block 4 flatter, avoiding interference problems caused by the protruding screw head, and also reducing the risk of the screw head being subjected to external wear and corrosion.

[0043] The lower end of the fixing plate 5 is flush with the lower end of the fixing block 4. This design enhances the compactness and stability of the overall structure. The flush lower ends allow the fixing block 4 and fixing plate 5 to evenly distribute pressure when subjected to force, avoiding stress concentration in a certain area due to height differences. At the same time, in actual installation, this flush setting facilitates docking with other components, reduces installation errors, and improves installation efficiency.

[0044] The distance between the connecting shaft 7 and the connecting beam 2 is less than the axial thickness of the roller 3. This dimensional relationship establishes a three-dimensional constraint system for the roller 3. In the axial direction, one end of the roller 3 is tightly fitted with the fixed plate 5, and the other end abuts against the connecting beam 2, forming a bidirectional limiting effect. In the radial direction, the connecting shaft 7 passes through the central hole of the roller 3, restricting its radial displacement. This design ensures that the roller 3 maintains a fixed motion trajectory during rolling, avoiding operational inaccuracies caused by axial movement or radial offset, and guaranteeing the stability of the clamping plate during movement. At the same time, the precise dimensional fit reduces the gaps between components, reduces abnormal friction caused by vibration or external forces, extends the service life of the roller 3, and ensures the reliability of the pulley structure during long-term operation.

[0045] The fixing block 4, fixing plate 5, cover 6, and connecting shaft 7 are integrated into one piece and made of metal. They are manufactured using a one-piece molding process and are made of metal. This manufacturing method eliminates gaps in the connections between components, such as welding and riveting, avoiding the risk of structural failure due to insufficient strength at the joints. The high strength and rigidity of the metal material ensure that the overall structure can withstand large external loads and maintain structural integrity during frequent disassembly and assembly or long-term operation of the plate heat exchanger.

[0046] 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.
