[0032] 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.

[0033] Please see Figure 1-6 This utility model provides a technical solution: a confined space flange bolt installation device, including: an installation unit 5, including a connecting component 51 sleeved on the nut 41 to be installed, a rotating component disposed on the side of the connecting component 51 away from the flange 3 for driving the connecting component 51 to rotate, and a transmission component 52 disposed between the connecting component 51 and the rotating component for transmitting kinetic energy.

[0034] It should be noted that during operation, when assembling two adjacent first ducts 1 and second ducts 2, the flanges 3 on the ducts are aligned, and the fixing bolts 4 are inserted into the positioning holes on the flanges 3. When it is necessary to fix the nut 41 to the fixing bolt 4 in the confined space between the first duct 1 and the second duct 2, the nut 41 is first installed on the connecting component 51, then the nut 41 is aligned with the fixing bolt 4 and inserted into the fixing bolt 4. When it is necessary to tighten the nut 41, the rotating component drives the transmission component 52 to rotate, thereby causing the connecting component 51 to drive the nut 41 to rotate, thus fixing the nut 41 to the fixing bolt 4. The transmission component 52 and the rotating component adopt a vertical layout design, which allows the operating direction to be adjusted to be parallel to the flange 3. Combined with the extended size of the rotating component, it allows personnel to complete the work outside the confined space, avoiding interference between tools and surrounding equipment, breaking through the operating limitations of narrow environments. While ensuring installation accuracy, it significantly improves the efficiency, safety, and adaptability of flange bolt installation in confined spaces, and is particularly suitable for high-requirement operation scenarios in narrow environments such as industrial pipelines and duct systems.

[0035] In one embodiment, the transmission assembly 52 includes: a rotating shaft 522 disposed inside the connecting box 521 and having one end passing through the connecting box 521 and fixedly connected to the fixing rod 512; a first gear 523 disposed inside the connecting box 521 and fixed on the rotating shaft 522; and a second gear 524 fixed on the rotating rod 53 and meshing with the first gear 523.

[0036] This design is for reference. Figure 4 ,as well as Figure 5 The rotating shaft 522 is connected to the fixed rod 512. Through the meshing of the first gear 523 and the second gear 524, the power is efficiently transmitted. When the rotating component is rotated, the second gear 524 meshes with the first gear 523, thereby driving the rotating shaft 522 to rotate. The first gear 523 and the second gear 524 are both bevel gears, which can realize the transmission of kinetic energy between the rotating component and the fixed rod 512. Thus, the angle of the connecting component 51 can be adjusted according to the position of the restricted area of ​​the first duct 1 and the second duct 2, so as to be applicable to different duct installation environments.

[0037] In one embodiment, the connecting component 51 includes: a collar 511, which is designed to be open on one side and is fitted onto the nut 41 for positioning and installing the nut 41; and a fixing rod 512, which is disposed on the side of the collar 511 away from the nut 41 for connecting the collar 511 to the transmission component 52.

[0038] This design is for reference. Figure 5The one-sided opening design allows the collar 511 to be horizontally inserted from the side of the nut 41. When assembling the first duct 1, considering the small distance between the flange 3 at the connection between the first duct 1 and the second duct 2, the installation of the bolts is limited by space. The nut 41 is placed inside the collar 511, and then the rotating assembly is rotated. The rotating assembly drives the transmission assembly 52 to move, which in turn causes the fixing rod 512 to drive the collar 511 to rotate, tightening the nut 41 onto the fixing bolt 4. This design is suitable for narrow installation environments at duct connections.

[0039] In one embodiment, the rotating assembly includes: a connecting box 521 disposed on the side of the fixed rod 512 away from the collar 511; a rotating rod 53 passing through the connecting box 521; and a turntable 531 disposed on the side of the rotating rod 53 located outside the connecting box 521.

[0040] This design is for reference. Figure 3 ,as well as Figure 6 As the core transmission component, the rotating rod 53, through the meshing of the second gear 524 and the first gear 523, allows the operator to apply rotational force to the rotating rod 53, which can be converted into the rotational force of the collar 511 and the rotational force of the nut 41 through the transmission assembly 52. ​​The size of the rotating rod 53 can be adjusted according to the position of the confined space of the air duct, so that the collar 511 can penetrate into the interior of the confined space to assemble the nut 41. By setting up this device, the labor intensity of installing bolts is significantly reduced, which is especially suitable for high-frequency operation scenarios.

[0041] In one embodiment, the mounting unit 5 further includes: a connecting rod 54 disposed on the connecting box 521; and a handle 541 disposed on the side of the connecting rod 54 away from the transmission assembly 52.

[0042] This design is for reference. Figure 3 The connecting rod 54 is fixed on the outside of the connecting box 521. When installing the nut 41, the worker holds the handle 541, then aligns the nut 41 in the collar 511 with the fixing bolt 4, and inserts the nut 41 into the fixing bolt 4. Then, the turntable 531 is rotated to rotate the collar 511 on the fixing bolt 4, thus fixing the nut 41 on the fixing bolt 4 and completing the assembly of the nut 41. The surface of the handle 541 can be integrated with anti-slip texture, curved grip groove or soft covering to improve hand grip stability.

[0043] In one embodiment, the collar 511 has a slot 51101 that abuts against the outer end face of the nut 41 for placing the nut 41.

[0044] This design is for reference. Figure 4 ,as well as Figure 5The slot 51101 fits tightly with the outer end face of the nut 41. Through shape matching (such as a hexagonal slot), the nut 41 is ensured to remain stable during rotation, thus improving installation accuracy.

[0045] Furthermore, if the embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relation to the specification. The significance or implied number of the indicated technical features is not specified. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
