Threaded through holes 7 are provided at the bottoms of the mounting columns 4, enabling them to be threadedly sleeved on the transmission lead screws 6. When the transmission lead screws 6 rotate, the mounting columns 4 will move up and down along the axis of the lead screws, thereby driving the upper lifting platform 5 to adjust its height to meet the requirements of different construction heights.

[0023] In one embodiment, an installation plate 8 is provided at the lower end of the inner cavity of the installation cylinder 3, and the installation plate 8 divides the inner cavity of the installation cylinder 3 into a transmission cavity and a driving cavity.

To drive the rotation of the transmission lead screw 6, an installation plate 8 is provided at the lower end of the inner cavity of the installation cylinder 3, dividing the inner cavity of the installation cylinder 3 into a transmission cavity and a driving cavity. The transmission lead screw 6 is rotatably arranged on the installation plate 8, while the outer wall of the installation column 4 is slidably arranged in the transmission cavity. A worm gear 9 located in the driving cavity is provided at the bottom of the transmission lead screw 6, which is a key component for power transmission. A driving shaft 11 is rotatably arranged on the traveling base 1 through an installation sleeve 10, and one end of the driving shaft 11 is powered by a driving motor 12.

[0024] In one embodiment, the clamping mechanism includes an installation frame 14. A lower support seat 15 is provided at the bottom of the inner frame of the installation frame 14. An upper pressing seat 16 is slidably arranged above the inner frame of the installation frame 14. A lifting screw 17 is threadedly connected to the installation frame 14, and the lower end of the lifting screw 17 is rotatably connected to the upper part of the upper pressing seat 16. By rotating the lifting screw 17, the upper pressing seat 16 can be pushed up and down to clamp or release the HVAC pipe. To enhance the clamping effect and protect the surface of the HVAC pipe, V-shaped grooves 18 are provided above the lower support seat 15 and below the upper pressing seat 16, and rubber pads are laid in the V-shaped grooves 18 to increase friction and reduce wear.

[0025] To adapt to HVAC pipes of different sizes, side plates 19 are provided on both sides of the upper end of the lifting platform 5, and a guiding column 20 is connected between the two side plates 19.

An adjusting screw 21 is also rotatably arranged on the side plate 19, and the free end of the adjusting screw 21 is rotatably connected to the lower part of the installation frame 14. By rotating the adjusting screw 21, the installation frame 14 can be pushed to move along the guiding column 20, thereby adjusting the distance between the two clamping mechanisms. To improve the operation convenience, turning handles 22 are provided at the ends of the lifting screw 17 and the adjusting screw 21.

[0026] Working principle: The working principle of the lifting equipment for HVAC construction described in this application is as follows: The equipment realizes flexible movement through the walking wheels 2 at the bottom of the walking base 1 and ensures stability during operation through the locking function. Its core function is to be able to adjust the height of the HVAC pipes to be installed as needed. After the driving motor 12 is started, it drives the worm 13 to rotate through the drive shaft 11. The worm 13 meshes with the worm gear 9 at the bottom of the inner cavity of the installation cylinder 3, and then drives the transmission lead screw 6 to rotate synchronously. Since the bottom of the installation column 4 is provided with a threaded through hole 7 and is threadedly connected to the transmission lead screw 6, the rotation of the transmission lead screw 6 will cause the installation column 4 to move up and down in the installation cylinder 3, thereby realizing the height adjustment of the lifting platform 5. The HVAC pipe clamping mechanism on the lifting platform 5 realizes the stable clamping of the HVAC pipe through the cooperation of the lifting screw 17 and the upper pressing seat 16, as well as the design of the lower support seat 15 and the V-shaped groove 18. In addition, by adjusting the cooperation of the adjusting screw 21 and the guide post 20, the distance between the two clamping mechanisms can be adjusted to adapt to HVAC pipes of different sizes. The entire adjustment process is manually operated through the turning handle 22, which is simple and efficient, fully meeting the requirements for precise height adjustment of HVAC pipes in HVAC construction.
