Description

Technical Field

[0001] The utility model relates to the technical field of HVAC installation, in particular to a HVAC installation auxiliary device. Background Art

[0002] HVAC is a central air conditioner for each household. The biggest feature of central air conditioner is that it can create a comfortable indoor environment. The common split air conditioner in the home can only solve the problem of heating and cooling, but cannot solve the air treatment process. HVAC can solve the above problems very well.

[0003] The air treatment process has the following steps: first, after the air comes in, in addition to introducing fresh air, the air can be cooled and then filtered. After filtering, several major features are added: first, an electronic dust collector is added, which can mainly capture very small particles of dust. Generally speaking, it can capture one micron dust, and most of the dust within the range are bacteria, viruses, smoke, or odors, which can be filtered out; the other is to add a humidification device, which can create a relative humidity of about 40% in our room, so that people will feel very comfortable.

[0004] At present, when installing the indoor unit of the HVAC, manual handling is generally used. This method is time-consuming, labor-intensive and prone to safety accidents. For this reason, we propose a HVAC installation auxiliary device to assist workers in installing the indoor unit quickly and safely. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a HVAC installation auxiliary device to solve the technical problems mentioned in the above background.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a HVAC installation auxiliary device, including a base plate, a universal wheel is installed at the bottom end of the base plate, and an electromagnetic slide is installed at the top end of the base plate, a slider adapted to the electromagnetic slide is installed in the electromagnetic slide, and the outer wall of the slider is connected to multiple groups of connecting rods through a rotating shaft, and each two groups of the connecting rods are rotatably connected through a rotating shaft, and a support platform is installed at the top end of the connecting rod, a mounting plate is provided on one side of the end face of the support platform, and a lifting plate is installed on the top end of the mounting plate, and a hydraulic cylinder for driving the lifting plate to rise and fall is installed inside the mounting plate.

[0007] By adopting the above technical solution, workers can be assisted in installing the indoor unit, thereby reducing the burden on workers and greatly improving safety, and can also effectively improve installation efficiency and quality.

[0008] The utility model is further configured such that vertical rods extending to the inside of the bottom plate are fixed to the outer walls on both sides of the support platform, and an extrusion rod is fixed to the bottom outer wall of the vertical rod, a driven rod that can be squeezed and driven by the extrusion rod is arranged above one side of the extrusion rod, and a connecting rod is fixed to the outer wall of the vertical rod above the driven rod, and a wedge block is fixed to the bottom end of the connecting rod, and a wedge-shaped groove adapted to the wedge block is opened in the inner wall of the driven rod.

[0009] By adopting the above technical solution, the driven rod can be driven and reset.

[0010] The utility model is further configured that the end of the driven rod is fixedly connected with the first tooth wall rod, and the outer side of the first tooth wall rod is provided with a mounting frame.

[0011] By adopting the above technical solution, the tooth wall rod can be installed effectively.

[0012] The utility model is further configured that a second toothed wall rod is also installed in the installation frame, and a driving gear meshingly connected with the second toothed wall rod and the first toothed wall rod is installed between the second toothed wall rod and the first toothed wall rod.

[0013] By adopting the above technical solution, a driving effect on the limit plate is achieved.

[0014] The utility model is further configured such that the bottom ends of the first tooth wall rod and the second tooth wall rod are both fixedly mounted with limiting plates, and the limiting plates are arranged on the outside of the universal wheel.

[0015] By adopting the above technical solution, a limiting effect on the universal wheel is achieved.

[0016] In summary, the utility model mainly has the following beneficial effects:

[0017] 1. The utility model sets a connecting rod and an extension lifting plate. First, the indoor unit is placed on the lifting plate, and then the bottom plate is pushed to move to the installation area. At this time, the worker can stand on the support platform and start the electromagnetic slide. Then the slider will move in the electromagnetic slide and drive the connecting rod to rotate. After the connecting rod rotates, the support platform will be lifted, thereby driving the worker and the indoor unit to move to a higher place. Further, the hydraulic cylinder is started, and the hydraulic cylinder drives the lifting plate to move, thereby further lifting the indoor unit. After lifting to an appropriate position, it can stop. At this time, the worker can install the indoor unit. The above structure not only greatly improves safety, but also reduces the burden on workers, thereby effectively improving installation efficiency and quality.

[0018] 2. The utility model sets a driven rod, a toothed wall rod and a limit plate. During the rising process of the support platform, it will drive the vertical rod to move. After the vertical rod moves, it will squeeze the driven rod through the extrusion block to move. After the driven rod moves, it will push the first toothed wall rod to move. Then, under the action of the driving gear, the second toothed wall rod will also move. Therefore, the two sets of limit plates will move to the outer wall of the universal wheel to squeeze and limit the universal wheel, thereby ensuring the stability of the base plate.
