[0002] As a key component for air transport and distribution in urban rail transit, ductwork systems are typically assembled using flange connections. Flanges are connectors fixed to both ends of a single duct and are crucial for ensuring the stability and efficiency of the ductwork system. Due to the large number of ducts in urban rail transit systems and the specific length requirements for individual ducts, a large number of flange bolts are needed to complete these connections.

[0003] Traditional flange bolt installation methods require installation one by one, which is not only time-consuming but also greatly reduces construction efficiency, making it difficult to meet the needs of rapid construction and maintenance. Therefore, a rapid installation device for flange connection bolts in subway ducts is proposed. Utility Model Content

[0019] 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.

[0020] Please see Figure 1-4 In this embodiment of the utility model, a quick installation device for connecting bolts of a subway duct flange includes a fixing plate 1 and a bolt fixing plate 3. Multiple sets of guide rods 2 penetrating the bolt fixing plate 3 are installed on the end face of the fixing plate 1 adjacent to the bolt fixing plate 3. The guide rods 2 are fixedly connected to the fixing plate 1 and the bolt fixing plate 3, establishing a stable space between them and providing support points for multiple sets of transmission components. The number of guide rods 2 is not limited. In this embodiment, preferably, there are two guide rods 2, symmetrically arranged on both sides of the fixing plate 1 to ensure stability between the fixing plate 1 and the bolt fixing plate 3. Multiple sets of transmission components driving the bolt body 9 to rotate are provided between the bolt fixing plate 3 and the fixing plate 1. The outer circumferential surfaces of the multiple sets of transmission components are all connected to the transmission belt 10. The number of transmission components is not limited. In this embodiment, preferably, there are seven transmission components, and each transmission component is equipped with a corresponding bolt body 9.

[0021] Please see Figure 1 In one embodiment, preferably, it further includes a nut fixing plate 4, which is located on the side of the bolt fixing plate 3 away from the fixing plate 1. The ends of the multiple sets of guide rods 2 all pass through the nut fixing plate 4. The nut fixing plate 4 and the guide rods 2 are movably connected. The nut fixing plate 4 and the bolt fixing plate 3 are located on two non-adjacent sides of the duct connection, so that the connection is located between the bolt fixing plate 3 and the nut fixing plate 4. This ensures that the end of the bolt body 9 passes through the through hole at the connection and enters the nut body 14, thus meeting the basic conditions for subsequent rapid installation. The ends of the multiple sets of guide rods 2 are threaded with adjusting nuts 5, which are located on the side of the nut fixing plate 4 away from the bolt fixing plate 3. By adjusting the position of the adjusting nuts 5 on the guide rods 2, not only can the distance between the nut fixing plate 4 and the bolt fixing plate 3 be adjusted, but the nut fixing plate 4 can also be disassembled and assembled on the guide rods 2.

[0022] Please see Figure 1 In one embodiment, preferably, the transmission component includes a rotating rod 6 and a transmission gear 7 mounted on the outer circumference of the rotating rod 6. The two ends of the rotating rod 6 are respectively connected to the fixed clamping plate 1 and the bolt fixing plate 3. The transmission gear 7 is connected to the transmission belt 10. The transmission gear 7 has external teeth, and the inner wall of the transmission belt 10 has internal teeth. The external teeth on the transmission gear 7 mesh with the internal teeth on the transmission belt 10. When one of the transmission gears 7 rotates, the other transmission gears 7 connected to the transmission belt 10 will also rotate synchronously under the action of the transmission belt 10.

[0023] Please see Figure 2In one embodiment, preferably, a fixing sleeve 8 is installed at the end of the rotating rod 6 near the bolt fixing plate 3. The end of the fixing sleeve 8 forms an opening that matches the end of the bolt body 9. A magnetic block is provided in the opening of the fixing sleeve 8 to restrict the position of the bolt body 9, so as to ensure that the bolt body 9 will not easily fall out after being inserted into the fixing sleeve 8. The principle of the screwdriver end can be referred to here, and will not be elaborated in detail.

[0024] Please see Figure 1 In one embodiment, preferably, a transmission column 12 is installed on the fixed plate 1. The end of the transmission column 12 is connected to the rotating rod 6. A hexagonal transmission shaft 11 is installed at the end of the transmission column 12 away from the rotating rod 6. Furthermore, the hexagonal transmission shaft 11 is rotated by an electric wrench. The hexagonal transmission shaft 11 controls the rotation of the transmission gear 7 below through the transmission column 12. Thus, multiple transmission gears 7 are simultaneously controlled to rotate by the transmission belt 10. That is, multiple bolt fixing sleeves 8 are rotated by the transmission gears 7 until all bolt bodies 9 are rotated into the nuts below, thus completing the rapid installation of the duct flange and improving the installation efficiency.

[0025] Please see Figure 3 In one embodiment, preferably, the end face of the nut fixing plate 4 near the bolt fixing plate 3 is provided with multiple sets of nut slots 13, the multiple sets of nut slots 13 correspond one-to-one with the positions of multiple sets of bolt bodies 9, and the multiple sets of nut slots 13 are provided with through holes penetrating the nut fixing plate 4, and the nut slots 13 are provided with nut bodies 14.

[0026] The working principle and usage process of this utility model are as follows: Select a matching quick-installation device based on the duct model and the required flange bolt model. First, place the nut fixing plate 4 and bolt fixing plate 3 on the non-adjacent sides of the duct connection, ensuring the connection is between the bolt fixing plate 3 and the nut fixing plate 4. Then, adjust the distance between the nut fixing plate 4 and the bolt fixing plate 3 by fitting an adjusting nut 5 onto the guide rod 2. This ensures the nut fixing plate 4 can only move upwards and not downwards. Finally, assemble the nut body 14 and the bolt body 9, and have the worker press down the bolt. The bolt fixing plate 3 is used to make the bolt body 9 pass through the through hole at the air duct connection and contact the internal thread of the nut body 14. Then, the electric wrench is used to control the rotation of the hexagonal drive shaft 11. The hexagonal drive shaft 11 controls the rotation of the transmission gear 7 below through the set transmission column 12. In this way, multiple transmission gears 7 rotate synchronously under the action of the transmission belt 10. At this time, the ends of multiple bolt bodies 9 are simultaneously screwed into the interior of the nut body 14. When the nut body 14 and bolt body 9 are installed, the adjusting nut 5 is unscrewed from the guide rod 2, and the nut fixing plate 4 can also be removed from the guide rod 2.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
