A support frame is formed by the base, columns, top beam and intermediate beam. During installation, the heat exchanger is installed by the cooperation of the support frame and the support arms. Although the support arms of the installation bracket of the traditional heat exchanger are fixedly arranged, which ensures the connection strength, it also limits that the installation bracket of the traditional heat exchanger can only be suitable for the installation of one model size of heat exchanger. Summary of the Utility Model

[0030] Embodiment 1
[0031] As Figures 1 to 5As shown in the figure, the present utility model discloses an installation bracket structure for a heat exchanger, which includes a base 10, a bottom steel pipe 20, a column 30, an intermediate cross beam 40, a rotating arm assembly 50, and a top beam 60. There are two bases 10, and the two bases 10 are connected by the bottom steel pipe 20 to form a support seat at the bottom position; a column 30 is vertically arranged on the upper surface of each base 10, and the tops of the two columns 30 are connected by the top beam 60; the two ends of the intermediate cross beam 40 are respectively sleeved on the two columns 30 through the rotating arm assembly 50 and can be locked, and the intermediate cross beam 40 is located between the base 10 and the top beam 60.
[0032] On the one hand, through the cooperative design of the base 10, the bottom steel pipe 20, the column 30, the intermediate cross beam 40, the rotating arm assembly 50, and the top beam 60, the structure is simple. On the other hand, the designed rotating arm assembly 50 can adapt to heat exchangers of various sizes.
[0033] As shown in Figures 1 to Figure 5 As shown in the figure, in this embodiment, assembly spaces 401 are respectively opened at the two ends of the intermediate cross beam 40, and the parts of the intermediate cross beam 40 on the upper and lower sides of the assembly spaces 401 are respectively the upper end ears 404 and the lower end ears 405; the rotating arm assembly 50 is rotatably arranged on the part of the column 30 located in the assembly space 401.
[0034] As shown in Figures 1 to Figure 5 As shown in the figure, in this embodiment, the rotating arm assembly 50 includes a sleeve 501, a sleeve limiting hole 502, a limiting protrusion 503, a rotating arm 504, and a sleeve 506. The sleeve 501 is sleeved on the column 30, and the two ends of the sleeve 501 respectively extend out of the upper end ear 404 and the lower end ear 405 along the axial direction, and sleeve limiting holes 502 are opened on the wall surfaces of the two ends of the sleeve 501. The sleeve 506 is sleeved on the part of the sleeve 501 between the upper end ear 404 and the lower end ear 405, and the rotating arm 504 that protrudes outward is arranged on the side wall of the sleeve 506;
[0035] When the intermediate cross beam 40 moves to a specified position (the specified position is determined by the operator according to the actual installation position of the heat exchanger) on the column 30, one end of the limiting protrusion 503 is fixedly connected to the column 30, and the other end of the limiting protrusion 503 passes through the sleeve limiting hole 502 and extends in a direction away from the column 30.
[0036] Through the cooperative design of the sleeve 501, the sleeve limiting hole 502, the limiting protrusion 503, and the sleeve 506, the entire rotating arm assembly 50 rotates more smoothly and is more evenly stressed.
[0037] As shown in FIGS. 1 to Figure 5 In this embodiment, a hinge joint 505 is provided at the movable end of the swing arm 504, and a rotating ear 507 is rotatably sleeved on the hinge joint 505 through a rotating shaft.
[0038] Through the cooperative design of the swing arm 504, the sleeve 506 and the rotating ear 507, it is avoided that when the middle cross beam 40 moves up and down on the column 30, dead angles are formed during the movement of the swing arm 504.
[0039] The specific parameters in the present utility model are as follows:
[0040] The swing arm 504 is made of a seamless steel pipe with a size of 1.219X18. The sleeve 506 is the main stress point. The swing arm 504 is mainly 700 mm long. The front end of the swing arm 504 is rotatably fitted with the rotating ear 507 through a rotating shaft. The column 30 is made of a seamless steel pipe with a size of 169X15. The middle cross beam 40 and the top beam 60 are made of a cross beam of No. 3 swing arm assembly 50 steel.
[0041] Working principle:
[0042] The installation steps are as follows (the installation steps are existing mature technologies):
[0043] Prepare the foundation: Ensure that the foundation is stable and meets the design requirements.
[0044] Install the column and the cross beam: According to the design drawings, install the base 10, the bottom steel pipe 20, the column 30 and the middle cross beam 40 on the foundation to form a support frame.
[0045] Install the tube bundle rack: Fix the tube bundle rack to the support frame.
[0046] Install the heat exchanger tube bundle: Place the tube bundle of the heat exchanger on the tube bundle rack and fix it.
[0047] Connect the pipeline interfaces: Connect the heat exchanger with the pipelines in the system to ensure tightness and safety.
[0048] Adjustment and inspection: Adjust the position of the middle crossbeam 40 on the column 30 (install a crane on the upper connecting ear in the middle of the top beam 60, connect the ropes of the crane, set a hook at the end of the rope, and hang the hook on the lower connecting ear at the middle position of the middle crossbeam 40. Drive the crane to drive the middle crossbeam 40 to move up and down on the column 30). At the same time, use the swing arm assembly 50 device to adjust the position of the tube bundle. After the position of the tube bundle is determined, one end of the limit protrusion 503 is fixedly connected to the 30, and the other end of the limit protrusion 503 passes through the sleeve limit hole 502 and extends in a direction away from the column 30, thereby restricting the movement of the middle crossbeam 40 on the column 30; it can adapt to the installation of heat exchangers of various sizes. Check whether all fixing devices and connections are firm.
[0049] Compared with the traditional non-rotatable support arm, after the present utility model improves the non-rotatable support arm into a swing arm structure (i.e., the swing arm assembly 50), the swing arm 504 is more flexible, the applicability is increased (suiting heat exchanger tube bundles with a diameter of 1.2 - 3.5 meters), the operation is more convenient, and the forces on the two swing arms 504 and the sleeve 506 are more stable and reliable; further, the swing arm 504 cooperates with the rotating ear 507 to avoid dead angles during the movement process.
[0050] At the same time, after the improvement, the occupation of large-scale machinery and equipment (crane) is reduced, the angle of the swing arm 504 can be adjusted, the force is more balanced and stable, and the safety is higher;
[0051] And the present utility model can complete the sleeving of a tube bundle with a single weight of fifty tons.
[0052] Embodiment 2
[0053] The other structures of this Embodiment 2 are the same as those of Embodiment 1, and the differences are as follows:
[0054] As shown in FIGS. 6 to Figure 7 In this embodiment, a rolling assembly is provided on the upper surface of the upper end ear 404 where the middle crossbeam 40 is located, and the rolling assembly and the limit protrusion 503 are arranged around the through hole of the upper end ear 404 in an alternating and spaced manner.
[0055] Through the design of the rolling assembly, when the middle crossbeam 40 moves up and down on the column 30, the contact area between the sleeve 501 and the column 30 is reduced, and the surface contact is changed into a rolling structure.
[0056] As shown in FIGS. 6 to Figure 7As shown in the figure, in this embodiment, the rolling component includes a mounting seat 402 and a roller 403. The mounting seats 402 are arranged in pairs on the upper surface of the upper end lug 404. A roller 403 is rotatably arranged between the two mounting seats 402, and the rotating outer wall surface of the roller 403 extends into a transition window correspondingly opened on the sleeve 501 until the rotating outer wall surface of the roller 403 rolls and fits with the outer wall surface of the column 30.
[0057] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
