Description

Technical Field

[0001] The utility model relates to the field of air duct connection structures, in particular to a flange structure and an air duct. Background Art

[0002] Industrial air ducts are generally connected by flanges. That is, the air duct sections are produced according to specifications, and the air duct joints are connected by flanges. The air duct flange in the related art is welded by four angle irons or bent steel bars, and then put on the air duct and welded again, which is easy to generate stress. Some means are needed to release the stress before it can be used. During processing, since the flange and the air duct are actually connected by welding, they are often transported only after welding is completed. The flange during transportation is a protruding structure, which is very easy to deform and damage during transportation. Therefore, each transportation requires additional reinforcement, which not only increases the workload but also affects the transportation efficiency. Utility Model Content

[0005] The support portion comprises a support rod, two ends of which are connected to each other via connecting portions, and the support rod is used to be fixed on the side wall of the air duct.

[0006] The support rod is provided with a mounting hole along the axial direction of the air duct.

[0007] The support rod includes a main body, a horizontal extension wing is provided on the end surface of the main body flush with the air duct, a vertical extension wing is provided on the end surface of the main body abutting against the air duct, and a hook perpendicular to the extension wing is provided on the edge of the horizontal extension wing away from the main body.

[0011] The utility model adopts the following technical scheme to realize the wind pipe: an air pipe comprises a plurality of pipe sections, each of which is provided with a group of flange structures at both ends, and adjacent pipes are connected by using the flange structures.

[0012] Compared with the prior art, the flange structure and the air duct in the present application can be transported separately during transportation, and the air duct itself is a regular structure, which can make the most of the limited transportation space. In addition, the flange structure can be further disassembled into a connecting part and a supporting part. After the whole is folded, the volume is small, and the remaining corner space after the air duct crashes can be reasonably used to maximize the utilization of the transportation space and improve transportation efficiency.

DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0020] Reference Figure 1-5The wind duct in the utility model includes a plurality of pipe sections 2 and a flange structure 1 for connecting adjacent pipes 2. Take the pipe 2 in the form of a square air duct as an example, that is, the air duct formed by the combination of a plurality of pipe sections 2 and the flange structure 1 is also a square air duct as a whole. Specifically, a set of flange structures 1 needs to be set at both ends of each pipe section 2. When the pipes 2 are connected to each other, the end of the previous pipe section 2 is connected to the head end of the next pipe section 2, and the connection method between the two adjacent pipe sections 2 is to connect and fix them by using adjacent flange structures 1. The flange structure 1 itself can be fixed to the end of the pipe 2 by bolt connection or other convenient disassembly methods, and then when the entire air duct is packaged and transported, the pipe 2 and the flange structure 1 can be disassembled and packed and loaded at the same time. The flange structure 1 can be further disassembled into a connecting part 12 and a supporting part 11. After the overall volume is folded, the volume is small, and the remaining corner space after the air duct crashes can be reasonably used to maximize the utilization of the transportation space and improve the transportation efficiency. During transportation, since the air duct itself has a regular structure, no additional protective measures are required, which not only improves the space utilization efficiency, but also reduces the possibility of air duct deformation during transportation, while reducing the workload when loading the air duct.

[0021] One embodiment of the flange structure 1 is that the flange structure 1 includes a support portion 11 and a connection portion 12, wherein the support portion 11 is used for detachably connecting with the side wall of the air duct, and the connection portion 12 is installed at both ends of the support portion 11 for connecting adjacent support portions 11, and the support portions 11 are connected to each other through the installation portion to form a closed figure. Taking a square air duct as an example, in order to match the shape of the air duct, the closed figure formed by the support portion 11 and the connection portion 12 is also square and fits the outer wall of the air duct. Among them, the support portion 11 includes a support rod 111, and the two ends of the support rod 111 are respectively connected to each other through the connection portion 12, and the support rod 111 is used to be fixed on the side wall of the air duct. Still taking a square air duct as an example, correspondingly, the support rod 111 can be made into a straight rod shape, and then perfectly fit with the side wall of the air duct. If the air duct is a round tube, then the support rod 111 needs to be bent into a matching circle, and also needs to perfectly fit the outer wall of the air duct. When the cross section of the air duct is a square, four support rods 111 are required. When the cross section of the air duct is other polygons, the number of support rods 111 corresponds to the number of sides of the polygon, such as a hexagon requires six support rods 111.

[0022] When adjacent pipes 2 need to be connected, the adjacent support rods 111 need to be opposite and fit together. Of course, there needs to be certain sealing measures between the adjacent support rods 111, such as crimping sealing pads. At this time, a mounting hole 116 can be opened on the support rod 111 along the axial direction of the air duct, and it can be fixed by tightening with bolts, or it can also be fixed by welding to ensure the airtightness of the connection of the pipe 2.

[0023] One embodiment of the support rod 111 includes a main body 112, a horizontal extension wing 113 is provided on the end face of the main body 112 flush with the air duct, a vertical extension wing 114 is provided on the end face of the main body 112 abutting against the air duct, and a hook 115 perpendicular to the extension wing is provided on the edge of the horizontal extension wing 113 away from the main body 112. During assembly, the hook 115 can be used to hang the head end of the next section of the pipe 2 on the hook 115 at the end of the previous section of the pipe 2 for easy assembly. In some occasions where the air tightness requirement is not high, the hook 115 can be only welded or connected using the connecting part 12 after being mounted. Since the pipes 2 are actually already in a hanging mode through the hook 115, it is easier to align.

[0024] The main body 112 can be a square tube, and the fixing method between the main body 112 and the connecting part 12 can be bolt fixing. Specifically, the end of the main body 112 is provided with a mounting hole 116 for installing the connecting part 12. During assembly, the corresponding hole position is provided on the connecting part 12 to be opposite to the mounting hole 116, and then fixed by the combination of bolts and nuts. In order to enhance the fixing strength, it can also be further welded after the bolts and nuts are fixed. Of course, all fixing methods that require welding are on-site welding methods to ensure the space utilization efficiency during transportation. That is, during transportation, the main body 112 and the connecting part 12 are actually separated to maximize the use of transportation space.

[0025] The connecting part 12 includes a connecting plate 121, and a supporting platform 122 is provided on the lower end surface of the connecting plate 121. The edge of the supporting platform 122 extends toward the main body 112 and is inserted into the main body 112 and fixedly connected with the side wall of the main body 112. The supporting platform 122 can be fixed to the side wall of the pipe 2 by bolts, and the connection between adjacent pipes 2 mainly depends on the connection between adjacent connecting plates 121. In order to enhance the connection strength and facilitate alignment, a supporting plate 123 extending outward is provided at the edge of the connecting plate 121. When assembled, the supporting plate 123 extends toward the horizontal extension wing 113 and is inserted under the horizontal extension wing 113. A step surface 124 is provided between the supporting plate 123 and the connecting plate 121, and the edge of the horizontal extension wing 113 contacts the step surface 124. That is, during the actual assembly, not only can the hooks 115 be connected to each other, but the supporting plate 123 and the horizontal extension wing 113 can also cooperate. In addition to playing the role of limiting and aligning, the main body 112 and the connecting plate 121 can also be maintained on the same horizontal plane, which is convenient for later fixed installation.

[0026] Compared with the prior art, the flange structure 1 and the air duct in the utility model can be transported separately during transportation, and the air duct itself is a regular structure, which can make the most of the limited transportation space. In addition, the flange structure 1 can be further disassembled into a connecting portion 12 and a supporting portion 11. After the overall volume is folded, it is small, and the remaining corner space after the air duct crashes can be reasonably used to maximize the utilization of the transportation space and improve transportation efficiency. During transportation, since the air duct itself is a regular structure, no additional protective measures are required, which can not only improve the space utilization efficiency, but also reduce the possibility of deformation of the air duct during transportation, and at the same time reduce the workload when loading the air duct.

[0027] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
