[0019] The present invention provides a HVAC construction lifting device. It has the following beneficial effects:
[0020] (1) When the position of the adjusting arm of the HVAC construction lifting device needs to be adjusted, it is only necessary to rotate the block to prevent it from blocking the clamping plate, and then move the connecting plate to drive the clamping plate to move, so that the clamping plate leaves the wedge block, release the limit state of the wedge block, and then pull the wedge block upward to make the clamping part leave the cross plate, so as to easily change the position of the adjusting arm on the cross plate. This design greatly improves the adaptability of the device to pipes of different sizes. At the same time, the clamping stability between the wedge block and the clamping part is strong and will not fall off. This ensures that during the lifting process, the clamping structure can firmly fix the pipe and ensure the safe construction.
[0021] (2) The HVAC construction lifting device can drive the threaded rod to move spirally on the inner wall of the adjustment seat by rotating the turntable, thereby changing the position of the abutment block. When the abutment block is away from the gear ring, the limiting state of the gear ring can be released. At this time, the rotating arm can be rotated to adjust the angle, driving the rotating shaft and the gear ring to rotate synchronously. Then rotate the turntable in the opposite direction to make the abutment block approach the gear ring again, so that the limiting teeth on the abutment block are engaged with the limiting tooth grooves on the gear ring, and the gear ring is fixed, thereby fixing the angle of the rotating arm. This flexible angle adjustment function further improves the adaptability of the device, enabling it to better adapt to HVAC pipes of different shapes.
[0022] (3) A rotating block is provided in the HVAC construction lifting device to limit the clamping plate to avoid accidents due to accidental touch. A notch groove is provided on the clamping ring, and multiple groups of notch grooves are provided.
