Description

Technical Field

[0001] This utility model belongs to the field of hoisting technology, specifically relating to a hoisting structure for a parallel plate-fin heat exchanger. Background Technology

[0002] In traditional large heat exchanger hoisting processes, lifting lugs are typically installed on both sides of the heat exchanger, with a clamp attached to the middle. This method can damage the heat exchanger, especially during the hoisting process, where uneven stress or improper operation may damage the main structure. Furthermore, this hoisting method is technically challenging, requiring precise operation and strict safety measures to ensure a successful hoisting process.

[0003] For large heat exchangers connected in parallel, this hoisting method significantly increases the risks. Since parallel heat exchangers require precise alignment and fixation, any deviation during hoisting can lead to assembly errors, thereby affecting the overall system's operating efficiency and safety. Furthermore, traditional hoisting methods may cause varying degrees of damage to the heat exchanger fins, such as fin deformation, which can affect the heat exchanger's heat exchange efficiency and lifespan, resulting in adverse effects.

[0004] Therefore, there is an urgent need to develop a new hoisting structure to improve the safety and efficiency of hoisting parallel plate-fin heat exchangers while reducing potential damage to the heat exchangers. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a hoisting structure for a parallel plate-fin heat exchanger.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] This utility model provides a hoisting structure for a parallel plate-fin heat exchanger, including a base frame, a positioning mechanism, a corner brace mechanism, a shelf, and lifting lugs;

[0008] The positioning mechanism includes a first positioning frame and a second positioning frame arranged at intervals. The first and second positioning frames have identical structures, each including two extension rods, a positioning crossbeam, and a crossbeam. One end of each extension rod is vertically fixed to the base frame via a fastener, and the other end extends outward. The crossbeam is vertically fixed between the other ends of the two extension rods. The positioning crossbeam is arranged parallel to the crossbeam and the base frame, and the spacing between the positioning crossbeams is adjustable for positioning parallel plate-fin heat exchangers of different sizes. Below the second positioning frame, two parallel shelves for placing parallel plate-fin heat exchangers are arranged at intervals, and the shelves are fixedly connected to the second positioning frame via fasteners. Both the first and second positioning frames are equipped with lifting lugs for easy hoisting.

[0009] The corner bracing mechanism includes a first corner bracing rod and a second corner bracing rod. The first corner bracing rod is provided between the first positioning frame and the base frame, and the second corner bracing rod is provided between the shelf and the base frame.

[0010] Preferably, the base frame includes multiple horizontal beams and vertical beams, which are arranged perpendicularly to each other to form an integral frame structure.

[0011] Preferably, reinforcing plates are fixedly installed at the four corners of the base frame.

[0012] Preferably, a plurality of positioning support rods are vertically arranged between the base frame and the positioning crossbeam, and the two ends of the positioning support rods are fixedly connected to the base frame and the positioning crossbeam respectively.

[0013] Furthermore, reinforcing plates are fixedly installed on both sides of the connection between the positioning support rod and the positioning crossbeam.

[0014] Preferably, at least two diagonal braces are fixedly arranged between the extension rods of the first positioning frame and the second positioning frame, and the diagonal braces and the extension rods form a triangular structure.

[0015] Preferably, the two shelves are fixed to the positioning beam and below the beam of the second positioning frame, respectively.

[0016] Preferably, the fastener is a bolted connection assembly formed by a combination of a washer, a hexagonal nut, and a hexagonal head bolt.

[0017] Preferably, the positioning beam and the beam are provided with positioning elements to limit the movement of the parallel plate-fin heat exchanger.

[0018] Preferably, the base frame, positioning mechanism, corner bracing mechanism, and shelf are all made of channel steel.

[0019] Compared with the prior art, this utility model has the following advantages:

[0020] The lifting structure for parallel plate-fin heat exchangers provided by this invention uses a structure composed of multiple channel steels to secure the heat exchanger from all angles. Lifting lugs can be installed at multiple locations as needed, and can be used individually or collectively for lifting. This lifting structure utilizes a stable triangular structure to position, support, and protect the heat exchanger, ensuring that the parallel plate-fin heat exchanger is not deformed or otherwise damaged during lifting and assembly. This lifting structure not only improves the safety and efficiency of heat exchanger lifting but also reduces the risk of damage to the heat exchanger fins, thereby guaranteeing the heat exchanger's heat exchange efficiency and service life.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0029] like Figure 1 and Figure 2 As shown, in a preferred embodiment of this utility model, this embodiment provides a hoisting structure for a parallel plate-fin heat exchanger, including a base frame 1, a positioning mechanism 2, a corner bracing mechanism 3, a shelf 4, and lifting lugs 5. The base frame 1 includes multiple horizontal and vertical beams, which are arranged perpendicularly and intersectingly to form an integral frame structure. The base frame 1 can flatten the irregular parallel plate-fin heat exchanger and manifold, and in actual hoisting, the base frame 1 can handle hoisting and fixing work at different angles. Reinforcing plates 8 are also fixedly installed at the four corners of the base frame 1 to prevent deformation and displacement during hoisting. The positioning mechanism 2 is vertically fixed to the base frame 1, and the corner bracing mechanism 3 is fixedly connected to both the base frame 1 and the positioning mechanism 2 to improve the stability of the entire hoisting structure. The hoisting structure is designed with a large-sized base frame, which enhances the overall stability and impact resistance, thus providing better protection for the heat exchanger if the hoisting structure is subjected to external forces during hoisting.

[0030] like Figure 1 and Figure 3 As shown, in the structure provided in this embodiment, the positioning mechanism 2 includes a first positioning frame 2-1 and a second positioning frame 2-2. The first positioning frame 2-1 and the second positioning frame 2-2 have the same structure and are arranged vertically at intervals. Figure 4 As shown, both the first positioning frame 2-1 and the second positioning frame 2-2 include two extension rods 2-11, a positioning crossbeam 2-12, and a crossbeam 2-13. Taking the structure of the first positioning frame 2-1 as an example, one end of each of the two extension rods 2-11 is vertically fixed to the base frame 1 via a fastener, and the other end extends outward. The crossbeam 2-13 is fixed between the other ends of the two extension rods 2-11, and both ends of the crossbeam 2-13 are vertically fixed to the two extension rods 2-11 via fasteners. The positioning crossbeam 2-12 is arranged parallel to the crossbeam 2-13 and the base frame 1. The distance between the positioning crossbeam 2-12 and the crossbeam 2-13 can be adjusted according to the size of the parallel plate-fin heat exchanger to be hoisted, so as to achieve positioning of parallel plate-fin heat exchangers of different sizes.

[0031] Below the positioning beams 2-12 and 2-13 of the second positioning frame 2-2, there is a shelf 4 for placing parallel plate-fin heat exchangers. The two shelves 4 are arranged in parallel and spaced apart, and are fixedly connected to the second positioning frame 2-2 by fasteners. In this embodiment, the shelf 4 is made of channel steel with bent ends, which has a simple structure and high load-bearing capacity. Both the extension rods 2-11 of the first positioning frame 2-1 and the second positioning frame 2-2 are provided with lifting lugs 5 for lifting. In this embodiment, the lifting lugs 5 are located in the middle of the extension rods 2-11, so that the structure on both sides of the heat exchanger can be evenly stressed during lifting, ensuring the stability of the lifting. In other embodiments, lifting lugs 5 can also be provided at the two connecting ends of the two extension rods 2-11 and the beams 2-13, depending on the actual situation, to adapt to different lifting needs.

[0032] In the structure provided in this embodiment, corner bracing mechanisms 3 are also provided on both sides of the first positioning frame 2-1 and the second positioning frame 2-2 to improve the stability of the overall structure. The corner bracing mechanism 3 includes two first corner bracing rods 3-1 and two second corner bracing rods 3-2. The two ends of the two first corner bracing rods 3-1 are fixedly installed to the first positioning frame 2-1 and the base frame 1 respectively. The first corner bracing rods 3-1, the extension rods 2-11 of the first positioning frame 2-1, and the base frame 1 form a stable triangular structure. A second corner bracing rod 3-2 is provided between the shelf 4 and the base frame 1. The second corner bracing rod 3-2, the extension rods 2-11 of the second positioning frame 2-2, and the base frame 1 also form a stable triangular structure. Due to the large mass of the heat exchanger, in this embodiment, the end of the second corner brace 3-2 near the second positioning frame 2-2 is bent, which can improve the bending resistance of the second corner brace 3-2 to a certain extent. Both ends of one of the shelves 4 are fixedly connected to the bent portion of the second corner brace 3-2, allowing for more stable support of the heat exchanger during hoisting. To further improve the stability of the hoisting structure, at least two diagonal braces 6 are fixedly installed between the extension rods 2-11 of the first positioning frame 2-1 and the second positioning frame 2-2. In this embodiment, only two diagonal braces 6 are installed, forming a triangular structure with the extension rods. In practical application, this design not only stably supports the first positioning frame 2-1 and the second positioning frame 2-2, but also increases the protection area on both sides, making the fixing space of the parallel plate-fin heat exchanger more secure and the hoisting process safer. In other embodiments, the number of diagonal braces 6 can be increased or decreased depending on the size and weight of the parallel plate-fin heat exchanger being hoisted.

[0033] like Figure 1 and Figure 4As shown, to improve the stability and load-bearing capacity of the first positioning frame 2-1 and the second positioning frame 2-2, and to reduce the deformation of the first positioning frame 2-1 and the second positioning frame 2-2 due to collisions during hoisting, which could lead to displacement of the parallel plate-fin heat exchanger, several positioning support rods 7 are provided between the positioning beam 2-12 and the base frame 1. The two ends of the positioning support rods 7 are vertically fixed to the base frame 1 and the positioning beam 2-12 respectively by fasteners. The size and number of the positioning support rods 7 can be adjusted according to the size and weight of the heat exchanger. Furthermore, since the parallel heat exchanger requires precise alignment and fixation, any deviation during hoisting may lead to assembly errors, thereby affecting the operating efficiency and safety of the entire system. Therefore, positioning components 9 are provided on the beam 2-13 to further fix the position of the heat exchanger, prevent displacement during hoisting, and enhance structural stability. Reinforcing plates 8 are fixedly installed on both sides of the positioning support rod 7 near the positioning beam 2-12 via fasteners to prevent deformation and displacement of the positioning support rod 7 under external force. In this embodiment, the base frame 1, positioning mechanism 2, corner brace mechanism 3, shelf 4, diagonal brace 6 and positioning support rod 7 are all made of channel steel, and the connection nodes between each component are fixed by fasteners, wherein the fasteners are bolt connection assemblies formed by a combination of washers, hexagonal nuts and hexagonal head bolts.

[0034] The embodiments described above are merely preferred solutions of this utility model, and are not intended to limit the scope of this utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this utility model. Therefore, all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
