[0021] Referring to Figure 1 and Figure 2 , the embodiment of the present application discloses an integrated device for hanger rod positioning and installation and static installation and fixation of air ducts, which includes: The mobile trolley 1 is used to carry and move the device. It is set as a long type that can be placed along the installation direction of the air duct, and has moving wheels 25 at the bottom. Specifically, it can be in the structure of an electric vehicle and can be controlled to move by a driver or by a computer. A plurality of hydraulic jacks 2 are arranged on the mobile trolley 1, and an operating platform 3 is jointly installed on the output ends of the plurality of hydraulic jacks 2. A ladder 5 is arranged between the mobile trolley 1 and the operating platform 3 to facilitate the operator to climb onto the operating platform 3 through the ladder 5 for auxiliary operations.

[0022] The support platform 4 is arranged on the mobile trolley 1 in a liftable manner. Specifically, the support platform 4 is arranged on the upper end face of the operating platform 3.

[0023] The lifting frame 8 is installed on the mobile trolley 1 and is used to lift the air duct 13 to be installed. Specifically, it can be a chain hoist or a gear hoist, and a lifting motor 23 is installed thereon as the lifting power source.

[0024] The laser measuring instrument 12 is installed on the support platform 4 and is used for coordinate positioning of the suspender. Its measuring direction is set vertically upward.

[0025] The suspender drilling machine 11 and the suspender installer 10 are both slidably installed on the support platform 4 and are used to install the vertical suspender 16 at a predetermined coordinate. Among them, the suspender drilling machine 11 has three operation buttons, which are respectively used to control the short-distance rise, short-distance fall of the suspender drilling machine 11 and the drilling of the motor drill bit. The suspender installer 10 also has three operation buttons, which are respectively used to control the long-distance rise, long-distance fall of the suspender installer 10 and the extrusion and fixed installation of the suspender. And The hydraulic docking device 15 is used to statically press and fix the air duct 13 to be installed on the lifting frame 8 with the installed air duct joint 14. And, a slide rail is arranged on the support platform 4. The suspender drilling machine 11, the suspender installer 10 and the hydraulic docking device 15 are all installed on the corresponding electric trolleys. By controlling the movement of the corresponding electric trolleys, the distances between the suspender drilling machine 11, the suspender installer 10 and the hydraulic docking device 15 can be adjusted to ensure positioning.

[0026] Among them, referring to Figure 3 and Figure 4 , the hydraulic docking device 15 includes: The base 27 is slidably arranged on the support platform 4. Specifically, it is installed on one of the above-mentioned electric trolleys.

[0027] The double-headed threaded rod 20 is rotatably arranged on the base 27. The spiral directions of the threaded grooves at both ends are opposite, and the double-headed threaded rod 20 is perpendicular to the length direction of the mobile trolley 1.

[0028] The guide rod 21 is fixedly connected to the base 27 and is parallel to the double-headed threaded rod 20.

[0029] There are two slider blocks 28 which are slidably sleeved on both ends of the guide rod 21, and the end of the double-headed threaded rod 20 threadedly penetrates through the slider block 28 at the same end.

[0030] A rotary motor 19 is installed on the base 27 and is used to drive the double-headed threaded rod 20 to rotate. And A hydraulic mechanism 18 is installed on the slider block 28, and specifically includes: A hydraulic cylinder 29, whose cylinder body is installed on the slider block 28.

[0031] There are two riveting and welding plates 17 which are respectively fixed on the cylinder body of the hydraulic cylinder 29 and the end of the piston rod. The riveting and welding plates 17 are in a "C" shape, and the two opposite riveting and welding plates 17 on the two slider blocks 28 are assembled to form a frame adapted to the air duct joint 14. And There are multiple welding heads 26 which are spaced apart and distributed on one side of one of the riveting and welding plates 17 close to the other riveting and welding plate 17. In a feasible embodiment, the welding heads 26 are distributed on the same riveting and welding plate 17; in another feasible embodiment, multiple welding heads 26 are provided on the opposite sides of the two riveting and welding plates 17, and the multiple welding plates on both sides are arranged in a staggered manner.

[0032] In addition, referring to Figure 1 and Figure 2 , a sliding bracket 9 is slidably arranged on the lifting frame 8, and a lifting motor 23 for driving the sliding bracket 9 to move up and down on the lifting frame 8 is installed on the lifting frame 8; and, a small baffle 22 is arranged on one side of the sliding bracket 9 close to the installed air duct joint 14. When the end of the air duct 13 to be installed slides to the end on the sliding bracket 9 and is in close contact with the small baffle 22, the end of the air duct 13 to be installed is flush with the installed air duct joint 14. A plurality of sliding small wheels 7 are rotatably installed on one side of the mobile trolley 1 away from the small baffle 22.

[0033] Thus, when installing the air duct through the integrated device of the present application, first move the mobile trolley 1 to the general position of the pipeline installation, perform coordinate positioning of the vertical suspender 16 through the laser measuring instrument 12, and then continue to control the mobile trolley 1 to accurately move to the installation position of the vertical suspender 16; subsequently, according to the installation height of the air duct, the support platform 4 is smoothly lifted to the corresponding height through a plurality of hydraulic jacks 2, and according to the horizontal spacing of the vertical suspenders 16, the horizontal spacing of the suspender installation instrument 10, the suspender drilling machine 11 and the hydraulic docking device 15 is adjusted in sequence by the electric trolley.

[0034] When installing the vertical suspender 16, after leaving a drill hole on the floor slab 6 through the suspender drilling machine 11, place the vertical suspender in the suspender installation instrument 10, and then lift the vertical suspender 16 on the suspender installation instrument 10 to a long distance to the drill hole on the floor slab 6, and fix the expansion head on the vertical suspender 16 in the drill hole by upward extrusion.

[0035] Then, manually lift the duct 13 to be installed onto the multiple sliding wheels 7 on the mobile trolley 1, and use the sliding wheels 7 to convey the duct 13 to be installed to the sliding bracket 9 with less effort, and make the left side of the duct 13 to be installed closely adhere to the small baffle 22. Then start the lifting motor 23 to lift the duct 13 on the sliding bracket 9 through the lifting frame 8 until the height of the duct 13 to be installed is the same as that of the installed duct. Subsequently, the operator climbs up to the operating platform 3 through the ladder 5 to finely adjust the duct 13 to be installed to align it with the duct joint 14 of the installed duct; start the rotating motor 19 to drive the double-headed threaded rod 20 to rotate. When the double-headed threaded rod 20 rotates, it drives the two bases 27 to move closer to each other, so that the two riveting and welding plates 17 on the same base 27 are arranged on both sides of the duct joint 14, and the two opposite riveting and welding plates 17 on the two bases 27 enclose one side of the duct joint 14 to form a closed frame shape and correspond to the entire area of the duct joint 14; then start the hydraulic cylinder 29 to move the duct 13 to be installed towards the duct joint 14 of the installed duct. When the welding head 26 on the riveting and welding plate 17 closely adheres to the duct joint 14 of the installed duct, the welding head 26 on the riveting and welding plate 17 can weld the duct 13 to be installed to the duct joint 14 of the installed duct in one forming, without using fixing screws, greatly saving manpower, with higher installation efficiency and better sealing performance.

[0036] After the ducts are butted and fixed, connect the duct lower drag bar 24 and the pre-installed vertical suspender 16 with nuts to bear the gravity of the ducts. Thus, the installation of one section of the duct is completed, and the installation of the next section of the duct can continue.

[0037] The embodiment of the present application also discloses an integrated construction method for suspender positioning installation and duct static installation and fixing. Based on the above integrated device for suspender positioning installation and duct static installation and fixing, the following technical solutions are adopted: An integrated construction method for suspender positioning installation and duct static installation and fixing, referring to Figure 1 and Figure 2 , includes the following steps: S1. Freely move through the mobile trolley 1, first move to the approximate position of the pipeline installation; use the laser measuring instrument 12 to position the coordinates of the suspender, and precisely move to the precise position of the vertical suspender 16 by controlling the mobile trolley 1; S2. Raise the support table 4 to the corresponding height according to the installation height of the duct, and adjust the horizontal spacing of the suspender installation instrument 10, the suspender drilling machine 11 and the hydraulic docking device 15 according to the horizontal spacing of the vertical suspenders 16; S3.

The boom installer 10 has three operation buttons, which respectively control the long-distance rising, long-distance falling of the boom installer 10 and the extrusion and fixing installation of the boom. During operation, first lower the boom installer 10 over a long distance, then place the vertical boom 16 inside the boom installer 10, and then raise the boom installer 10 over a long distance to the drilling position on the floor slab 6. Fix the boom expansion head in the drill hole by upward extrusion. S5. Manually lift the air duct onto the multiple sliding small wheels 7 on the lifting frame 8, and transfer the air duct to the sliding bracket 9 through the sliding small wheels 7. Keep it closely against the small baffle 22 on the left side, and the small baffle 22 is flush with the installed air duct joint 14. Then start the lifting motor 23 to transfer the air duct upward through the lifting frame 8. Stop the transfer when the height of the air duct is the same as the height of the installed air duct, and then align the end of the air duct to be installed 13 with the installed air duct joint 14. S6. Fix the air duct to be installed 13 and the installed air duct joint 14 by riveting and welding through the hydraulic docking device 15. Specifically, start the rotating motor 19 to drive the double-headed threaded rod 20 to rotate. When the double-headed threaded rod 20 rotates, it drives the two bases 27 to approach each other, so that the two riveting and welding plates 17 on the same base 27 are arranged on both sides of the air duct joint 14, and the two opposite riveting and welding plates 17 on the two bases 27 enclose one side of the air duct joint 14 to form a closed frame shape and correspond to the entire area of the air duct joint 14. Then start the hydraulic cylinder 29 to move the air duct to be installed 13 towards the installed air duct joint 14. When the welding heads 26 on the riveting and welding plates 17 are closely attached to the installed air duct joint 14, the welding heads 26 on the riveting and welding plates 17 can weld the air duct to be installed 13 to the installed air duct joint 14. S7. Connect and fix the air duct horizontal drag bar and the vertical boom 16 with nuts to bear the gravity of the air duct. S8. Repeat the above steps to complete the installation of the next section of the air duct.
