[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] As shown in the figure, the present invention discloses a new method for quickly installing an air duct riser, comprising the following steps:

[0029] Step S1: Calculate the weight of the required hanging air duct 1 and reasonably select the number of arm groups;

[0030] Step S2: Slide the lifting vehicle 2 to the vicinity of the pipe shaft via the roller 3 below, measure the specifications of the air duct, adjust the positions of the horizontal arm 4 and the longitudinal arm 5, and turn on the electromagnet 6 to hold the air duct 1;

[0031] Step S3: Then slide the lifting vehicle 2 to the side of the pipe well, adjust the positions of the lifting vehicle 2, the horizontal arm 4 and the longitudinal arm 5 so that the air duct 1 is horizontally positioned in the position to be installed, and fix the roller 3 of the lifting vehicle to prevent it from shaking left and right;

[0032] Step S4: Install the air duct 1;

[0033] Step S5: The motor 7 is started by the remote controller to drive the wire rope 8, so that the slide 9 slowly rises to the installation position of the air duct 1;

[0034] Step S6: When the hoisted air duct 1 is directly above the installed air duct, slowly lower the slideway to align the flanges of the two air duct sections, and use bolts or flange strips to fix the air ducts together. If it is the first air duct section, skip the two air duct section fixing step;

[0035] Step S7: Finally, secure the duct to the floor using a bracket and turn off the electromagnetic switch. Installation is complete. This method allows the duct to be installed on the ground first, reducing construction difficulty. Electromagnets are used to hold the duct in place, minimizing damage to the galvanized coating and protecting the finished duct.

[0036] In step S4, when the air duct 1 is installed from bottom to top, the air duct between the current floor and the upper floor is installed on the upper floor, and the two sections of the air duct 1 are butt-jointed and fixed on the current floor; when the air duct is installed from top to bottom, the air duct between the current floor and the upper floor is installed on the lower floor, and the two sections of the air duct are butt-jointed and fixed on the upper floor.

[0037] In step S6, if the installation is from top to bottom, the suspended air duct is located directly below the installed air duct.

[0038] In step S7, the first section of the installed air duct must be fixed on the floor or roof first, and the remaining short-circuit air ducts that do not pass through the floor are not fixed first and are fixed to the wall / ring beam later.

[0039] The slideway 9 comprises a horizontal plate 91 and two vertical plates 92, each mounted on either side of the two horizontal plates 91. A reinforcing rod 93 is mounted between the two vertical plates. The two vertical plates pass through a limit block 10, which is mounted on the lifting vehicle 2. The slideway is actually a support frame used to mount and drive the longitudinal and transverse arms to move up and down.

[0040] There are slide grooves 921 on both sides of the vertical plate 92, and sliders 11 are installed at the slide grooves 921. There are multiple mounting holes on the vertical plate 92. The slider 11 is connected to the vertical plate 92 through fasteners. One end of the horizontal arm 4 is installed on the slider 11, and the longitudinal arm 5 is connected to the horizontal arm 4. The electromagnet 6 is installed at the longitudinal arm 5, and the air duct 1 is located between the longitudinal arms 5 on the two vertical plates.

[0041] Two groups of vertically distributed longitudinal arms 5 and transverse arms 4 are installed on each slider 11. The specific number of groups is determined according to the size of the air duct.

[0042] The longitudinal arm 5 and the transverse arm 4 are both telescopic structures. That is, the length of the longitudinal arm and the transverse arm can be adjusted. Use air ducts of different specifications, specifically, air ducts of different diameters.

[0043] One end of the steel wire rope 8 is mounted in the middle of the horizontal plate 91, a fixed roller 12 is mounted in the middle of the top of the lifting vehicle 2, a motor 7 is mounted at the lower end of the lifting vehicle 2, and the other end of the steel wire rope 8 is mounted on the output end of the motor 7. When the motor 7 is working, the steel wire rope 8 is wound, driving the slide 9 to move vertically.

[0044] In one embodiment of the present invention, rollers are installed on the bottom of the lifting vehicle.

[0045] When the weight of the duct to be installed exceeds the magnetic force required by the electromagnet, an additional set of arms can be added to increase the magnetic attraction and improve the safety of the duct installation. Due to the high-frequency electromagnet, only one set of arms is normally required.

[0046] The construction equipment and method provided by the present invention improve construction efficiency and safety.

[0047] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
