Description

Technical Field

[0001] This utility model relates to the field of HVAC equipment installation technology, and in particular to an HVAC equipment installation tool. Background Technology

[0002] Heating, ventilation, and air conditioning (HVAC) is an important component of buildings. It includes three aspects: heating, ventilation, and air conditioning. HVAC systems are widely used equipment. During the installation process, especially for indoor wall-mounted units, which often need to be installed at a high position, traditional installation methods usually involve installers climbing to the height and manually supporting the indoor units. This inevitably results in a lot of climbing and manual support work, which is very time-consuming, labor-intensive, and also has certain dangers.

[0003] A search revealed Chinese Publication No. CN222476119U, which discloses an installation tool for HVAC equipment, including a platform, a scissor lift device, a support plate, and a foot pedal. The support plate is mounted on the platform via the scissor lift device, which drives the support plate to move up and down, supporting the equipment to be installed. The foot pedal is connected to the support plate via a telescopic connecting assembly, allowing the support plate to move the foot pedal up and down. The telescopic connecting assembly is adjustable in length. This utility model allows the HVAC indoor unit to be installed to be placed on the support plate, with the installer standing on the foot pedal, and the indoor unit and the installer rising together. Simultaneously, the telescopic connecting assembly can extend to a certain length and then stop, ensuring a suitable distance between the support plate and the foot pedal for the installer. This design avoids the need for climbing and supporting the equipment, making installation safer and more convenient.

[0004] However, in actual use, the above-mentioned device uses casters to support the ground during the lifting and lowering of HVAC personnel and staff. First, this can lead to damage to the casters and affect their service life. Second, the casters directly support the ground, which can cause instability and reduce the safety of the device. At the same time, the lack of protective devices on the lifting platform can lead to the safety hazard of HVAC personnel and staff falling from the platform due to the instability of the device.
