[0019] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, describe in detail the specific embodiments, structures, features and their effects of the present utility model as follows.

[0020] As Figure 1-2 shown, an air duct lifting device includes a telescopic structure and a rebounding structure. The rebounding structure is installed at both ends of the telescopic structure and can rebound and be embedded into the installation holes at both ends of the air duct to horizontally fix the air duct. The upper end of the telescopic structure is provided with a connecting plate 8, and there are two lifting holes 801, one on the left and one on the right, on the connecting plate 8, which are connected to the lifting arm through ropes to lift the telescopic structure.

[0021] In the above embodiments, the telescopic structure includes a threaded pipe 1 and a threaded rod 2. The threaded pipe 1 and the threaded rod 2 are connected by threads, and the overall length of the telescopic structure can be adjusted by the threads to adapt to air ducts of different specifications and sizes. The resilient structures are respectively installed at one end of the threaded pipe 1 and the threaded rod 2. The overall length of the telescopic structure is adjusted to be able to be embedded between the mounting plates at both ends of the air duct, and the resilient structures at one end of the threaded pipe 1 and the threaded rod 2 are embedded into the mounting holes of the air duct to achieve a stable installation. The connecting plate 8 is located at the upper end of the threaded pipe 1. When adjusting the length of the telescopic structure, only the threaded rod 2 needs to be adjusted, which does not affect the hoisting operation. During the construction operation, if it is found that the length of the telescopic structure does not correspond to the distance between the connecting plates 8 at both ends of the air duct, it can be adjusted and corrected in time. Cylinders 4 are provided at both ends of the telescopic structure, and the resilient structures are installed in the cylinders 4. After the cylinders 4 are aligned with the mounting holes of the air duct, the resilient structures can rebound from the cylinders 4, that is, one end of the resilient structure protrudes outside the cylinder 4 to fix the air duct. The resilient structure includes a spring 6 and a slider 7. The slider 7 is slidably connected in the cylinder 4. The cylinder 4 provides auxiliary force and guidance for the slider 7, while the spring 6 is elastically connected between the slider 7 and the cylinder 4. After the slider 7 is pressed into the cylinder 4, the slider 7 can rebound and protrude outside the cylinder 4, that is, the slider 7 is embedded into the mounting hole of the air duct. A limiting groove 401 is provided on the side of the cylinder 4, and a limiting plate 701 is provided on the side of the slider 7. The limiting plate 701 is slidably connected in the limiting groove 401 to limit the stroke of the slider 7 to prevent the slider 7 from disengaging from the cylinder 4 and losing the resilient function. At the same time, the limiting plate 701 also provides a force application point for personnel operation to facilitate pulling the slider 7 to compress the spring 6. An anti-slip structure 702 is provided at one end of the slider 7. After the slider 7 is embedded into the mounting hole of the air duct, the anti-slip structure 702 and the mounting hole restrain each other to prevent the slider 7 from slipping in the mounting hole, thereby preventing the air duct from being unstable and shaking during installation.

[0022] In the above embodiments, a nut 3 is threadedly connected to the threaded rod 2. The nut 3 can abut against one end of the threaded pipe 1 to reinforce the connection between the threaded pipe 1 and the threaded rod 2 and prevent the length of the telescopic structure from changing. A wrench position 101 is provided on the side of the threaded pipe 1 to facilitate the fixing of the threaded pipe 1 and the tightening operation of the threaded rod 2 and the nut 3. A lifting ring is provided on the side of the threaded rod 2 and can be connected to the boom through a rope to further enhance the stability of the hoisting. The lifting rings are arranged in a circumferential array on the side of the threaded rod 2. When the threaded rod 2 rotates to any angle, a corresponding lifting ring is arranged upwards, which is convenient for the hoisting operation.

[0023] Description of the working mode of the present utility model:

[0024] Connect a set of this device to the left and right of the jib arm through ropes respectively. Adjust the length of the telescopic structure according to the distance between the mounting plates at both ends of the air duct, that is, adjust by the threaded connection between the threaded pipe 1 and the threaded rod 2. After determining the length, press the nut 3 against one end of the threaded pipe 1 to fix the length of the threaded rod 2 in the threaded pipe 1. Press the sliders 7 at both ends of the telescopic structure into the cylinder 4, or pull the sliders 7 into the cylinder 4 by pulling the limit plate 701, so that both ends of the telescopic structure can be completely embedded between the mounting plates of the air duct. Align the cylinders 4 at both ends of the telescopic structure with the mounting holes at both ends of the air duct respectively. The sliders 7 automatically rebound under the action of the spring 6 and are embedded into the mounting holes, locking the air duct horizontally. At the same time, the anti-slip structure 702 on the sliders 7 can prevent the air duct from slipping, enhancing the stability of the installation. Fix the corresponding mounting holes at both ends of the air duct by the sliders 7, and then hoist it to the installation position through the jib arm and ropes. Align the sliders 7 with the mounting holes on the already installed air duct and embed the sliders 7 into the mounting holes of this air duct to achieve alignment. Install and fix the four mounting holes on the air duct in sequence with bolts. The sequence is to install and connect the two upper mounting holes first. After the newly connected air duct is initially hung on the side of the original air duct, gradually remove this device and install and connect the corresponding mounting holes, that is, pull the limit plate 701 to make the sliders 7 disengage from the mounting holes of the two air ducts. Using this device to hoist and connect the air duct is convenient and fast, greatly improving the installation efficiency of the air duct.

[0025] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
