[0028] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] Reference Figures 1 to 6 As shown, the utility model provides a plate heat exchanger installation auxiliary device, including: a reaction seat 1, two tie rods 4 and a hydraulic jack 5.

[0031] The plate heat exchanger 3 includes a fixed clamping plate 31 and a movable clamping plate 32. The movable clamping plate 32 is arranged between the support column 34 of the plate heat exchanger and the fixed clamping plate 31. By tightening the locking screw 33, the fixed clamping plate and the movable clamping plate clamp and seal the heat exchange plate.

[0032] In this embodiment, the reaction seat 1 is in the shape of a rectangular parallelepiped. A support leg 2 is mounted at the bottom of the reaction seat 1 to support the reaction seat 1. The length of the support leg 2 is adjustable. The reaction seat 1 has a front side facing the movable clamping plate 32 and a rear side facing away from the movable clamping plate 32.

[0033] See Figures 1 to 3 As shown, the reaction seat 1 is formed with a plurality of through-holes a, which are arranged along the length direction of the locking screw 33 , and the plurality of through-holes a are arranged at intervals along the width direction of the movable clamping plate 32 .

[0034] The outer diameter of the tie rod 4 matches the inner diameter of the through-hole a. There are two tie rods 4, each slidably mounted within the two through-holes a. The tie rods 4 are longer than the through-holes a, with both ends extending outside of the through-holes a. After being inserted through the through-holes a, the tie rods 4 align with the locking screws 33 on opposite sides of the center of the movable splint 32.

[0035] A locking member 41 is mounted on one end of the tie rod 4, near the locking screw. This member has a threaded locking hole extending axially along the tie rod 4. By threading the locking screw 33 into the locking member's threaded locking hole, the tie rod 4 and the locking screw 33 are coaxially connected. A retaining member 42 is mounted on the other end of the tie rod 4. In this embodiment, the retaining member 42 is a limit nut. The retaining member 42 is threaded onto the other end of the tie rod 4 and abuts against the rear side of the reaction seat 1.

[0036] In this embodiment, two hydraulic jacks 5 are provided, spaced apart along the width of the movable plate 32. The hydraulic jacks 5 are supported between the movable plate 32 and the reaction seat 1, and are symmetrically arranged about the vertical centerline of the movable plate 32. Preferably, a push plate 51 is removably mounted on the output end of each hydraulic jack 5. The presence of the push plate 51 increases the contact area between the output end of the hydraulic jack 5 and the movable plate 32, thereby enhancing the stability of the movable plate 32 as the hydraulic jack 5 pushes against it.

[0037] During the assembly process of tightening the heat exchange plate, the reaction seat 1 is supported on the hydraulic jack 5, and the output end of the hydraulic jack 5 extends to push the movable clamp 32 toward the fixed clamp 31 to move a predetermined distance. Through the cooperation of the reaction seat and the hydraulic jack, the operator can quickly and labor-savingly tighten the nut on the locking screw 33, thereby efficiently completing the assembly of the plate heat exchanger.

[0038] As a preferred embodiment, the bottom of the reaction seat 1 defines a receiving slot b, extending along the width of the movable plate 32. Two legs 2 are provided, one at each end of the receiving slot b. The upper ends of the legs 2 are hinged to the bottom of the slot b. The reaction seat 1 is detachably mounted with a locking member 6 for locking the upper ends of the legs 2.

[0039] For details, see Figure 2 、 Figure 4 and Figure 5 As shown, two limiting flanges 8 are formed at the bottom of the reaction seat 1. The two limiting flanges 8 are respectively arranged at the two ends of the accommodating groove b. A first locking hole c is formed at the upper end of the support leg 2, and a second locking hole d is formed on the limiting flange 8. The locking member 6 is detachably installed in the first locking hole c and the second locking hole d to lock the support leg 2. In this embodiment, the locking member 6 is formed with an external thread, and the first locking hole c and the second locking hole d are threaded holes. The locking member 6 is screwed into the first locking hole c and the second locking hole d to lock the support leg 2.

[0040] When using the plate heat exchanger installation auxiliary device of the present invention, the support leg 2 is supported on the reaction seat 1, thereby preventing the reaction seat 1 and the hydraulic jack 5 from pressing down the locking screw 33 due to their own gravity, causing the locking screw 33 to be deformed, and also increasing the stability of the reaction seat 1.

[0041] After the plate heat exchanger 3 is assembled, the locking piece 6 is removed to fold the legs 2. Figure 5 As shown, in this embodiment, a support ledge 7 is formed at the bottom of the receiving groove b, and the height of the support ledge 7 is adapted to the thickness of the support leg 2. One support leg 2 is hinged to the support ledge 7, and after the two support legs 2 are folded together, the two support legs 2 are superimposed and disposed in the receiving groove b.

[0042] After the two legs 2 are overlapped and arranged in the accommodating groove b, the locking member 6 is detachably installed in the second locking hole d (the locking member 6 is screwed into the second locking hole d), and the locking member 6 abuts against the outer leg 2 to lock the two legs 2, and then the two legs 2 are accommodated in the accommodating groove b.

[0043] As a preferred embodiment, the support leg 2 includes a socket 21, an extension rod 22, and a fine-tuning screw 23. One end of the socket 21 is hinged to the bottom of the receiving groove b, and the extension rod 22 is slidably mounted on the socket 21 along the axial direction of the socket 21. The socket 21 is equipped with a positioning member for locking the extension rod 22.

[0044] Specifically, the extension rod 22 defines a plurality of adjustment holes e spaced apart along the axial direction of the extension rod 22. The socket pipe 21 defines a positioning hole f connected to the adjustment hole e, with a positioning member inserted into the positioning hole f and one of the adjustment holes e. The lower end of the extension rod 22 defines a threaded hole extending along the axial direction of the extension rod 22. A fine-adjustment screw 23 is coaxially disposed with the extension rod 22 and screwed into the threaded hole of the extension rod 22.

[0045] To adjust the length of the support leg 2, first insert the positioning piece into the positioning hole f of the socket pipe 21 and the adjustment hole e of the extension rod 22, quickly completing the initial adjustment of the length of the support leg 2. Then, rotate the fine-adjustment screw 23 so that it rests on the ground. The coordination of the socket pipe 21, the extension rod 22, and the fine-adjustment screw 23 allows for quick and accurate adjustment of the length of the support leg 2, ensuring that the two support legs 2 provide stable support for the reaction seat 1.

[0046] In this embodiment, the outer diameter of the locking screw 33 and the outer diameter of the tie rod 4 are both adapted to the inner diameter of the through-hole a. Figure 6 As shown, when the locking screw 33 is longer, the end of the locking screw 33 ( Figure 6When the right end of the middle locking screw is far away from the movable splint 32, the locking screw 33 is directly passed through the through-hole of the reaction seat 1, and the retaining piece 42 is screwed into the locking screw and abuts against the rear side of the reaction seat 1. The hydraulic jack is supported between the movable splint 32 and the reaction seat 1. The movable splint 32 is pushed toward the fixed splint by the hydraulic jack to move a predetermined distance, thereby assisting the installation of the plate heat exchanger.

[0047] The plate heat exchanger installation auxiliary device of the present invention has a reaction seat with multiple groups of through-holes, so that it can meet the assembly requirements of plate heat exchangers of different specifications. When using the plate heat exchanger installation auxiliary device, first insert the two tie rods into the corresponding two through-holes on the reaction seat according to the horizontal distance between the locking screws on both sides of the movable splint. The tie rod is coaxially connected to the locking screw through a locking member, and the stop member of the tie rod rests on the rear side of the reaction seat. The hydraulic jack is supported between the movable splint and the reaction seat. In the assembly link of pressing the heat exchange plate, the reaction seat is supported by the hydraulic jack, and the output end of the hydraulic jack is extended to push the movable splint forward a predetermined distance, so that the movable splint and the fixed splint clamp the heat exchange plate. The operator can quickly and labor-savingly tighten the nut on the locking screw, thereby completing the assembly of the plate heat exchanger.

[0048] During use, the plate heat exchanger installation auxiliary device of this invention supports the two legs on the reaction base, thereby preventing the reaction base and the hydraulic jack from pressing down on the locking screw due to their own weight, causing deformation of the locking screw, and also increasing the stability of the reaction base. After the plate heat exchanger is installed, the two legs are stacked and stored in the receiving groove at the bottom of the reaction base, thereby reducing the space occupied by the plate heat exchanger installation auxiliary device of this invention, protecting the legs, and facilitating the storage and transfer of the plate heat exchanger installation auxiliary device.
