Description

Technical Field

[0001] This utility model belongs to the technical field of tunnel external ventilation fan installation, specifically relating to an installation structure for a tunnel internal and external ventilation fan. Background Technology

[0002] Ventilation is required in the tunnel using fans. The installation of these fans necessitates an installation mechanism, which currently consists of embedded parts and welded components. The embedded parts are pre-embedded in the concrete dome, while the welded components are welded onto them on-site using a welding mechanism. This provides the installation position for the fans within the embedded parts. The existing welded components consist of multiple studs. After welding these studs, the fans are lifted to a position below the welded components. The fans are then manually adjusted so that the studs pass through the mounting holes on the fans. This process requires multiple people to support the fans and prevent them from shifting, significantly increasing the workload for the installation workers and impacting the efficiency of the fan installation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] refer to Figure 1-2 As shown, the present invention provides an installation structure for an internal and external tunnel ventilation fan, comprising: a fan body 9 and an embedded plate 2 pre-embedded in the tunnel dome 1. Multiple studs 3 are arranged side by side on both sides of the bottom of the embedded plate 2. An installation component 4 for installing the fan body 9 is provided between the multiple studs 3 on the same side. Each installation component 4 has a T-shaped slot 5 that is horizontally opened through it. The fan body 9 is provided with two T-shaped blocks 6 that are horizontally engaged in the T-shaped slots 5 on the same side.

[0022] Combination Figure 1-3 As shown, each mounting component 4 includes an L-shaped integrated mounting part 13 and a docking part 12. A T-shaped slot 5 is formed through the docking part 12. The mounting part 13 is provided with mounting components that are mounted on multiple studs 3 on the same side.

[0023] As described above, using the fan body 9, corn arban, multiple studs 3, two mounting parts 4, and two T-shaped locking blocks 6 provided by this utility model, the docking part 12 on the mounting part 4 is detachably mounted on multiple studs 3 on the same side through the mounting part 13 and the mounting assembly, thereby detachably mounting the docking part 12 on the embedded plate 2. At this time, the fan body 9 is lifted to one side of the two docking parts 12, so that the two T-shaped locking blocks 6 on the fan body 9 are at the same height as the T-shaped locking slots 5 on the two docking parts 12. At this time, the fan body 9 is pushed horizontally, so that the two T-shaped locking blocks 6 are inserted horizontally into the two T-shaped locking slots 5 respectively, thereby suspending the fan body 9 below the two docking parts 12. At this time, there is no need to lift the fan body 9.

[0024] Furthermore, to facilitate alignment of the T-shaped locking block 6 with the second mounting hole 11 on the mating part 12, refer to Figure 2 and Figure 4 As shown, each T-shaped slot 5 has a stop 14 at its end to limit the T-shaped block 6. The stop 14 limits the T-shaped block 6 to be coaxially aligned with the second mounting hole 11 on the docking part 12. When the T-shaped block 6 is inserted laterally into the T-shaped slot 5, the stop 14 positions the T-shaped block 6 at the rear of the T-shaped slot 5, aligning the T-shaped block 6 with the axis of the second mounting hole 11 on the docking part 12, thereby facilitating the passage of the fixing bolt 7 through the docking part 12 and the T-shaped block 6.

[0025] Furthermore, in order to provide an installation position for the T-shaped clip 6 on the wind turbine body 9, refer to Figure 1 As shown, a mounting plate 8 is welded to the top of the fan body 9, and two T-shaped clips 6 are longitudinally welded to both sides of the top of the mounting plate 8. The mounting plate 8 provides mounting positions for the two T-shaped clips 6 on the fan body 9.

[0026] In this utility model, combined with Figure 1 and Figure 3 As shown, the two sides of the docking part 12 in this embodiment are provided with multiple fixing bolts 7 and multiple second nuts 16 respectively. The docking part 12 and the T-shaped locking block 6 are provided with second mounting holes 11 for the fixing bolts 7 to pass through. Each second nut 16 is screwed onto the corresponding fixing bolt 7.

[0027] As described above, when using the multiple fixing bolts 7 and multiple second nuts 16 provided by this utility model, after the T-shaped locking block 6 is engaged in the T-shaped locking groove 5, the multiple fixing bolts 7 pass through the second mounting hole 11 through the T-shaped locking block 6 and the mating part 12. After the second nut 16 is screwed onto the fixing bolts 7, the T-shaped locking block 6 is fixedly installed in the T-shaped locking groove 5. At this time, the T-shaped locking block 6 is restricted in the T-shaped locking groove 5, preventing the T-shaped locking block 6 from moving laterally in the T-shaped locking groove 5.

[0028] In this utility model, combined with Figure 1 and Figure 3 As shown, the mounting assembly of this embodiment includes a plurality of first nuts 15. The mounting part 13 is provided with a first mounting hole 10 through which a plurality of studs 3 pass. The plurality of first nuts 15 are respectively screwed onto the corresponding studs 3, and each first nut 15 abuts against the bottom of the mounting part 13.

[0029] As described above, when using the installation assembly provided by this utility model, before installing the fan body 9, the mounting part 13 on the mounting component 4 is attached to the embedded plate 2. At this time, the studs 3 on the embedded plate 2 pass through the mounting part 13 through the first mounting hole 10. Then, multiple first nuts 15 are screwed onto the multiple studs 3 respectively. After the multiple first nuts 15 abut against the mounting plate 8, the mounting plate 8 is stably installed on the embedded plate 2, thereby detachably installing the docking part 12 on the embedded plate 2, and thus providing an installation position for the T-shaped clip 6 on the embedded plate 2.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
