[0023] This utility model embodiment provides an assembly device for a plate heat exchanger, such as... Figure 1-4 As shown, the assembly device for the plate heat exchanger includes: a base 1; an adjustment frame 2 slidably mounted on the top of the base 1 for supporting and assisting in adjusting the position of the heat exchange plates of the heat exchanger; a hydraulic rod 3 fixed on the top of the adjustment frame 2 for adjusting the assembly height of the heat exchange plates; a connecting plate 4 mounted on the output rod of the hydraulic rod 3, with a lifting rope 5 installed at the bottom of the connecting plate 4, and a hook 6 fixed at the bottom of the lifting rope 5, the lifting rope 5 and the hook 6 used for suspending the heat exchange plates of the heat exchanger; and a limiting mechanism provided on the adjustment frame 2 for stabilizing the heat exchange plates.

[0024] In this embodiment, by setting the adjustment frame 2, the position of the heat exchanger plate is supported and adjusted, allowing the position of the heat exchanger plate to be flexibly adjusted during assembly, which helps to better coordinate with other components for assembly. By setting the hydraulic rod 3 (atos hydraulic cylinder CK40), the assembly height of the heat exchanger plate is adjusted to meet the needs of different assembly heights. By setting the connecting plate 4, lifting rope 5 and hook 6 to assist in hoisting the heat exchanger plate, the transfer operation of the heat exchanger plate is facilitated. By setting the limiting mechanism, the heat exchanger plate is stabilized, so that the mounting holes of the heat exchanger plate can be quickly aligned with the heat exchanger, solving the problem of low assembly efficiency caused by poor stability of the hoisting equipment, and greatly improving the assembly efficiency of the plate heat exchanger.

[0025] In a further preferred embodiment of the present invention, the limiting mechanism includes: a second threaded rod 15 threadedly mounted on the adjusting frame 2; a clamping plate 16 rotatably mounted on the second threaded rod 15 for clamping and stabilizing the heat exchange plate; an adjusting block 17 fixed on the second threaded rod 15 for providing an operating grip point; and a limiting rod 18 fixed on the clamping plate 16 and movably passing through the adjusting frame 2 for limiting the movement path of the clamping plate 16, wherein the limiting rod 18 is provided with scale lines for indicating the movement distance of the clamping plate 16.

[0026] In this embodiment, by setting the second threaded rod 15, the position of the clamping plate 16 can be adjusted to adapt to the clamping requirements of heat exchange plates of different sizes, thus providing flexible adjustment. The clamping plate 16 also serves to clamp and stabilize the heat exchange plates, preventing them from shaking or shifting during assembly. The adjusting block 17 provides an operating grip point, making it easier and less strenuous to rotate the second threaded rod 15. The limiting rod 18 limits the movement path of the clamping plate 16, ensuring the stability of its movement. At the same time, the scale lines on it indicate the movement distance of the clamping plate 16, making the adjustment more precise and further improving the efficiency and quality of plate heat exchanger assembly.

[0027] In a further preferred embodiment of the present invention, a limiting plate 7 connected to the adjusting frame 2 is slidably mounted on the base 1. The limiting plate 7 is provided with a sliding groove 8. A limiting block connected to the connecting plate 4 for stabilizing the connecting plate 4 is slidably mounted in the sliding groove 8. The top of the base 1 is provided with a triggering mechanism that can contact the limiting plate 7 for limiting the dwell position of the heat exchange plate.

[0028] In this embodiment, by setting a limiting plate 7 connected to the adjusting frame 2, the adjusting frame 2 is provided with additional support and guidance, which enhances the stability of the moving adjusting frame 2 and plays an auxiliary positioning role. By setting a sliding groove 8 on the limiting plate 7 and slidingly installing a limiting block connected to the connecting plate 4 in the sliding groove 8, the connecting plate 4 is stabilized, preventing the connecting plate 4 from shaking during hoisting and ensuring that the heat exchange plate moves smoothly. By setting a trigger mechanism on the top of the base 1 that can contact the limiting plate 7, the position of the heat exchange plate is limited, so that the heat exchange plate can accurately reach the predetermined assembly position, improving the assembly accuracy, and thus making the entire assembly process of the plate heat exchanger more efficient and accurate.

[0029] In a further preferred embodiment of the present invention, the triggering mechanism includes a mounting plate 19 fixed on the base 1, an electric telescopic rod 20 mounted on the mounting plate 19, an adjusting plate 21 fixed on the output rod of the electric telescopic rod 20, and a trigger button 22 disposed on the adjusting plate 21 and capable of contacting the limiting plate 7.

[0030] In this embodiment, by setting the mounting plate 19, a stable installation foundation is provided for the electric telescopic rod 20 (Delker LT30 electric push rod), ensuring the stability of the electric telescopic rod 20 and playing a supporting and fixing role. By installing the electric telescopic rod 20, the adjustment plate 21 can automatically extend and retract, eliminating the need for manual operation and improving work efficiency. By setting the adjustment plate 21, the trigger button 22 is supported and moved, ensuring that the trigger button 22 can accurately reach the position of contact with the limit plate 7. By setting the trigger button 22 on the adjustment plate 21, when it contacts the limit plate 7, a signal can be sent to control related actions, so that the heat exchange plate can accurately stop at the predetermined assembly position, improving the accuracy and automation of the plate heat exchanger assembly.

[0031] In a further preferred embodiment of the present invention, a fixing plate 11 is installed on the top of the base 1, and a first threaded rod 12 is rotatably installed on the fixing plate 11.

A stepper motor 14 with an output shaft connected to the first threaded rod 12 is fixed on the base 1 for driving the first threaded rod 12 to rotate.

[0032] In this embodiment, by setting the fixing plate 11, a stable installation foundation is provided for the first threaded rod 12, ensuring the smooth rotation of the first threaded rod 12 and playing a supporting and fixing role. By rotating the first threaded rod 12, it plays a key role in realizing transmission adjustment, enabling the power of the stepper motor 14 (NEMA 23) to be transmitted. By setting the slider 13 threadedly sleeved with the first threaded rod 12 and connected to the adjustment frame 2, and by allowing the slider 13 to slide and connect with the base 1, the rotational motion of the first threaded rod 12 is converted into the linear motion of the slider 13 and the adjustment frame 2, realizing precise adjustment of the position of the adjustment frame 2. By driving the first threaded rod 12 to rotate through the stepper motor 14, the adjustment process is automated, improving adjustment efficiency and accuracy, thereby improving the assembly efficiency and quality of the plate heat exchanger.

[0033] In a further preferred embodiment of the present invention, a support plate 9 for supporting a plate heat exchanger is installed on the top of the base 1, and an anti-slip pad 10 for increasing friction is fixed on the top of the support plate 9.

[0034] In this embodiment, by setting the support plate 9, a stable support platform is provided for the plate heat exchanger, ensuring that the heat exchanger has a stable foundation during assembly and playing a key role in bearing and supporting it. By fixing the anti-slip pad 10 on the top of the support plate 9, the friction is increased, preventing the plate heat exchanger from sliding or shifting on the support plate 9, thus improving the stability of the heat exchanger placement. This design allows the heat exchanger to maintain a fixed position during assembly, facilitating accurate assembly operations and reducing assembly errors caused by heat exchanger movement.

[0035] In a further preferred embodiment of the present invention, a safety rod for closing the opening of the hook 6 is hinged to the hook 6, the second threaded rod 15 and the clamping plate 16 are both arranged in groups, and the clamping plates 16 are each inlaid with balls 23 that can contact the heat exchange plate to reduce friction on the side that is close to each other.

[0036] In this embodiment, by hinged a safety rod to the hook 6, the opening of the hook 6 is closed, which prevents the heat exchange plate from accidentally falling off during hoisting and greatly improves the safety of hoisting operations. The second threaded rod 15 and the clamping plate 16 are set in groups, which makes the clamping of the heat exchange plate more stable and reliable, further ensuring the stability of the heat exchange plate during assembly. By embedding ball bearings 23 on the side of the clamping plates 16 that are close to each other, the friction between the clamping plates 16 and the heat exchange plate is reduced, making the movement of the heat exchange plate between the clamping plates 16 smoother and facilitating the position adjustment of the heat exchange plate. This improves the assembly efficiency of the plate heat exchanger and also reduces the wear on the surface of the heat exchange plate, extending its service life.

[0037] In a further preferred embodiment of the present invention, the top of the base 1 is provided with a guide groove, the slider 13 slides in contact with the inner wall of the guide groove, the guide groove is used to limit the movement path of the slider 13, and the trigger button 22 is used to adjust the start and stop of the stepper motor 14.

[0038] In this embodiment, by setting a guide groove on the top of the base 1 and making the slider 13 slide in contact with the inner wall of the guide groove, the effect of precisely limiting the movement path of the slider 13 is achieved, which plays a guiding and constraining role, ensuring that the slider 13 can move stably along the predetermined trajectory, thereby ensuring the accuracy of the position adjustment of the adjustment frame 2. By setting the trigger button 22 to adjust the start and stop of the stepper motor 14, the role of automatic control is achieved. When the limit plate 7 contacts the trigger button 22, the stepper motor 14 can be controlled to stop rotating in time, so that the adjustment frame 2 stops accurately in the predetermined position, which facilitates the assembly operation of the heat exchange plate, improves the automation level and assembly accuracy of the plate heat exchanger assembly, and effectively improves the assembly efficiency and quality.

[0039] In summary, compared with related technologies, this device flexibly supports and adjusts the position of the heat exchange plate through the adjusting frame 2, adjusts the assembly height through the hydraulic rod 3, uses the connecting plate 4, the lifting rope 5, and the hook 6 to lift the heat exchange plate, stabilizes the heat exchange plate through the limiting mechanism, limits the dwell position of the heat exchange plate through the triggering mechanism, achieves precise adjustment of the position of the adjusting frame 2 through the fixing plate 11, the first threaded rod 12, the slider 13, and the stepper motor 14, provides stable support through the support plate 9 and the anti-slip pad 10, prevents the heat exchange plate from falling off accidentally, reduces friction through the ball bearing 23, limits the movement path of the slider 13 through the guide groove, and automatically controls the start and stop of the stepper motor 14 through the trigger button 22.
