Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower support structures, in particular to a cooling tower support beam connection structure. Background Art

[0002] A cooling tower is a cooling device that includes a tower body and structures such as fillers and demisting condensation modules arranged inside the tower body. When working, industrial circulating water is sprayed on the fillers through the water distribution pipe, and heat is exchanged with the dry and cold air entering the tower body and flowing from bottom to top, thereby reducing the temperature of the circulating water. At the same time, the demisting condensation module is used to convert the saturated humid air after heat exchange into unsaturated air, so that the air discharged from the tower will not produce plume fog.

[0003] To install components such as fillers and demisting condensation modules, support beams are required within the tower. These support beams consist of longitudinal and transverse beams. Currently, to facilitate on-site installation, the beams are cut into multiple sections. During installation, these sections must be joined and then welded together. However, welding is difficult and requires high skill levels. Improper welding can easily lead to cracking. This is also costly and requires improvement in production efficiency. Furthermore, the welded connections between the longitudinal and transverse beams on the support beams hinder subsequent assembly and disassembly for replacement and maintenance.

[0010] Furthermore, the connecting plate is located in the cavity of the front crossbeam and the rear crossbeam.

[0011] Furthermore, a first mounting hole is provided on the longitudinal beam, a second mounting hole is provided on the front cross beam, and a distance L1 between the center of the first mounting hole and the side wall of the longitudinal beam is greater than a distance between the second mounting hole and a side end face of the front cross beam.

[0018] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0019] See also Figure 1 、 Figure 2 The utility model provides a cooling tower support beam connection structure, including a longitudinal beam 1, two oppositely arranged front cross beams 2 and two oppositely arranged rear cross beams 3, the two front cross beams 2 are located on opposite sides of the longitudinal beam 1, and the two rear cross beams 3 are located on opposite sides of the longitudinal beam 1. A connecting plate 4 is provided between the front cross beam 2 and the rear cross beam 3 on the same side of the longitudinal beam 1, part of the connecting plate 4 is in contact with the front cross beam 2, and the other part of the connecting plate 4 is in contact with the rear cross beam 3 on the same side. The longitudinal beam 1, the two front cross beams 2 and the two connecting plates 4 are fixedly connected by a first bolt 5 cooperated with a first nut 51, and the two front cross beams 2 and the two connecting plates 4 are fixedly connected by a second bolt 6 cooperated with a second nut 61.

[0020] When installing the cooling tower support beam connection structure of the present invention, first place the two front crossbeams 2 on opposite sides of the longitudinal beam 1. Then, place the connecting plate 4 on the side of the front crossbeam 2 away from the longitudinal beam 1, and securely connect the two front crossbeams 2 to the longitudinal beam 1 using the first bolt 5 in conjunction with the first nut 51. Next, place the two rear crossbeams 3 on the side of the connecting plate 4 close to the longitudinal beam 1, and securely connect the two rear crossbeams 3 to the longitudinal beam 2 using the second bolt 6 in conjunction with the second nut 61.

[0021] During the connection process, the two front crossbeams 2 are directly fixed to the longitudinal beam 1 using first bolts 5 in conjunction with first nuts 51. After the front crossbeams 2 are installed, the connecting plate 4 is fixed to the longitudinal beam 1. At this time, the two rear crossbeams 3 are fixed to the connecting plate 4 using second bolts 6 in conjunction with second nuts 61. In this way, the front crossbeams 2 and the rear crossbeams 3 are fixed to the longitudinal beam 1. Compared with traditional welding methods, this method is easier to install, greatly reduces the installation difficulty, saves production costs, improves production efficiency, and is easy to disassemble, facilitating replacement and maintenance.

[0022] In this embodiment, the side wall of the rear cross beam 3 close to the end of the front cross beam 2 is in contact with the side wall of the longitudinal beam 1. In this way, the longitudinal beam 1 can support the end of the rear cross beam 3, which is conducive to stably locking the rear cross beam 3 on the longitudinal beam 1 through the second bolt 6 and the second nut 61.

[0023] Furthermore, the C-shaped end surface of one end of the rear cross beam 3 fits with the C-shaped end surface of one end of the front cross beam 2, thereby achieving seamless connection between the front cross beam 2 and the rear cross beam 3, which is beneficial to maintaining the stability of the connection structure of the front and rear cross beams (2, 3).

[0024] As a preferred embodiment, a first bolt 5 is provided between the longitudinal beam 1, the two front cross beams 2, and the two connecting plates 4, with a first nut 51 being mounted on the tail end of the first bolt 5. Two second bolts 6 are provided between the two front cross beams 2 and the two connecting plates 4, with a second nut 6 being mounted on the tail end of each second bolt 6. In this embodiment, the front cross beam 2 is directly fixed to the longitudinal beam 1 via the first bolt 5, thereby ensuring the stability of the connection between the front cross beam 2 and the longitudinal beam 1. The rear cross beam 3 is indirectly fixed to the longitudinal beam 1 via the connecting plates 4. The provision of two second bolts 6 enhances the connection strength at this location, ensuring that the rear cross beam 3 can be securely locked to the longitudinal beam 1.

[0025] As a preferred embodiment, the longitudinal beam 1 is a square beam, the front cross beam 2 and the rear cross beam 3 are C-shaped beams with the same cross section, and the openings of the front cross beam 2 and the rear cross beam 3 are set away from the longitudinal beam 1. In this way, a larger fitting surface is ensured between the longitudinal beam 1 and the front cross beam 2 and the rear cross beam 3, thereby enhancing the connection stability.

[0026] In addition, the connecting plate 4 is located in the cavity of the front crossbeam 1 and the rear crossbeam 3, and the heads of the first bolt 5 and the second bolt 6 and the first nut 51 and the second nut 61 are all located in the cavity of the corresponding crossbeams, avoiding protruding structures on the front crossbeam 2 and the rear crossbeam 3, and having good appearance consistency.

[0027] Furthermore, a first mounting hole 11 is provided on the longitudinal beam 1, and a second mounting hole 21 is provided on the front cross beam 2, wherein the distance L1 between the center of the first mounting hole 11 and the side wall of the longitudinal beam 1 is greater than the distance L2 between the second mounting hole 21 and the end face of one side of the front cross beam 1. In this way, when the longitudinal beam 1 and the front cross beam 2 are perpendicular to each other, and the first mounting hole 11 and the second mounting hole 21 are aligned, the longitudinal beam 1 still has a certain area that can fit with the rear cross beam 3.

[0028] In this embodiment, a gasket 7 is provided on the end surface of the connecting plate 4 away from the longitudinal beam 1. During installation, the first bolt 5 and the second bolt 6 pass through the gasket 7 located on one side of the longitudinal beam 1, and the first nut 51 and the second nut 61 squeeze and fix the gasket 7 located on the other side of the longitudinal beam 1 on the connecting plate 4, thereby increasing the pre-tightening force of the first bolt 5 and the second bolt 6 and ensuring the connection stability.
