Description

Technical Field

[0001] The utility model belongs to the technical field of frame structures for air-cooling heat exchangers, and in particular relates to a guard plate frame connecting device for air-cooling heat exchangers. Background Art

[0002] The air-cooled heat exchanger guard plate connecting plate is a key component required to connect the side guard plate frame and the end middle guard plate frame, such as Figure 3 As shown, the side guard plate frame 4 is connected to the end middle guard plate frame 2 through a guard plate connecting plate 6. One end of the guard plate connecting plate 6 is welded to the side guard plate frame 4, and a connecting hole is set at the other end. At the same time, a connecting hole is designed on the end guard plate frame 1. The guard plate connecting plate 6 on the side guard plate frame 4 is connected to the connecting hole of the end guard plate frame 1 through bolts, and two or more rectangular air chambers are formed after connection.

[0003] The air chamber is composed of a side guard plate frame 4 and an end and middle guard plate frame 2. Since the size of the air chamber should remain exactly the same in a single-span frame, it is necessary to accurately design the position of the guard plate connecting plate 6 so that the end middle guard plate frame 2 is located in the center of the side guard plate frame 4. That is, when the guard plate connecting plate 6 is welded to the side guard plate frame 4, the guard plate connecting plate 6 deviates from one side of the center of the side guard plate frame 4 so that the end middle guard plate frame 2 is located exactly in the middle of the side guard plate frame 4 after being installed on the guard plate connecting plate 6. However, such a structure also brings certain inconveniences to the on-site installation and production. On the one hand, when assembling the side guard plate frames 4 on both sides, it is necessary to consider the connection direction on the side guard plate frames 4 so that the positions of the guard plate connecting plates 6 on both sides correspond to each other; on the other hand, it is also necessary to consider when installing the end middle guard plate frame 2, so that the end middle guard plate frame 2 is placed on the same side of the two guard plate connecting plates 6, otherwise the end middle guard plate frame 2 will be installed tilted; on the other hand, since the guard plate connecting plate 6 and the side guard plate frame 4 are welded, the side guard plate frames 4 and the guard plate connecting plates 6 cannot be universal during the frame assembly, and it takes time and effort to assemble them in pairs, which makes the on-site installation difficult and error-prone. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the utility model provides a guard plate frame connecting device for an air-cooled heat exchanger. The design structure is simple, and a detachable connection method is adopted to make the connecting plate dock with the side guard plate frame and the end middle guard plate frame respectively. During on-site assembly, the common effect of the side guard plate frame and the connecting plate can be achieved, which effectively reduces the production difficulty and prevents the problem of assembly errors.

[0005] The technical solution adopted by the utility model is: a guard plate frame connecting device for an air-cooled heat exchanger, comprising a central vertical plate arranged at the center position of a side guard plate frame and arranged in a vertical direction, connecting plates in contact with the central vertical plate are fixedly installed on the left and right sides of the central vertical plate, two connecting plates extend toward the center direction of the guard plate frame, and a gap is formed between the two connecting plates for accommodating the end middle guard plate frame, and one end of the end middle guard plate frame extends into the gap and is connected to the two connecting plates.

[0006] The connecting plate is provided with a plurality of through holes for connecting with the central vertical plate and the end guard plate frame.

[0007] The two connecting plates are symmetrically arranged relative to the central vertical plate, and the two connecting plates are installed on the central vertical plate by bolt connection.

[0008] The two connecting plates are connected to the end center guard plate frame by means of bolt connection.

[0009] The beneficial effects of the utility model are:

[0010] The utility model has a simple design structure and adopts a detachable connection method to make the connecting plate dock with the side guard plate frame and the end middle guard plate frame respectively, so that the common effect of the side guard plate frame and the connecting plate can be achieved during on-site assembly, which effectively reduces the production difficulty and prevents the problem of assembly errors.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1-3 As shown, a guard plate frame connecting device for an air-cooled heat exchanger includes a central vertical plate 5 arranged at the center position of the side guard plate frame 4 and arranged along the vertical direction. The central vertical plate 5 is a longitudinal rib plate on the side guard plate frame 4, which is located at the center position of the side guard plate frame 4. It can cooperate with other longitudinal rib plates to strengthen the overall structural strength of the side guard plate frame 4, and can also be connected to the connecting plate 3. At the same time, the side guard plate frame 4 as a whole can also be used as a universal frame.

[0018] Connecting plates 3 in contact with the center vertical plate 5 are fixedly installed on the left and right sides of the center vertical plate 5. The two connecting plates 3 extend toward the center direction of the guard plate frame, and a gap for accommodating the end middle guard plate frame 2 is formed between the two connecting plates 3. One end of the end middle guard plate frame 2 extends into the gap and is connected to the two connecting plates 3. The gap between the two connecting plates 3 is the center of the side guard plate frame 4. Inserting one end of the end middle guard plate frame 2 into the gap and connecting it with the connecting plate 3 can ensure that the end middle guard plate frame 2 is installed in the center position of the side guard plate frame 4, which is convenient and quick.

[0019] The connecting plate 3 is provided with a plurality of through holes for connecting with the central vertical plate 5 and the end guard plate frame 1 , and the number and size of the through holes are arranged according to the actual loads of the side guard plate frame 4 and the end center guard plate frame 2 .

[0020] The two connecting plates 3 are symmetrically arranged relative to the central vertical plate 5, and the two connecting plates 3 are installed on the central vertical plate 5 by bolt connection. The two connecting plates 3 are connected to the end middle guard plate frame 2 by bolt connection. More specifically, the bolts can be assembled after passing through the first connecting plate 3, the end middle guard plate frame 2 (or the central vertical plate 5), and the second connecting plate 3 in sequence, and are matched with flat washers, spring washers and nuts to increase firmness, and the assembly is convenient. Since the connecting plates 3 are detachably connected to the central vertical plate 5 and the end middle guard plate frame 2 by bolts, the size of the connecting plates 3 themselves can be adjusted according to the actual load, and the adaptability is higher.

[0021] This guard plate frame connecting device for an air-cooled heat exchanger can effectively solve the problem of the symmetrical structure of the side guard plate frame 4, making the side guard plate frame 4 a universal part in the same span frame, reducing the difficulty of production and solving the problem of difficult on-site installation.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
