Description

Technical Field

[0001] The invention relates to a mounting assembly, in particular to a vertical axial flow fan mounting assembly, belonging to the technical field of mounting assemblies. Background Art

[0002] Axial flow fans are widely used. They are fans that flow in the same direction as the axis of the fan blades. For example, electric fans and air conditioner outdoor fans are fans that operate in an axial flow manner. They are called "axial flow" because the gas flows parallel to the fan axis. Axial flow fans are usually used in situations where the flow rate requirements are high and the pressure requirements are low. Axial flow fans are fixed in position and move the air. Axial flow fans are mainly composed of fan impellers and casings. They have a simple structure but very high data requirements. Ordinary axial flow fans can be used for ventilation in general factories, warehouses, offices, residences and other places. They can also be used for air coolers (air coolers), evaporators, condensers, spray drops, etc.

[0003] When using an axial flow fan, it is necessary to use a mounting assembly to install and fix the fan. Therefore, a vertical axial flow fan mounting assembly is needed to meet the current market demand. Although a variety of mounting assemblies have been produced on the market, in general, there are still many common problems. First, most of the existing mounting assemblies are not provided with shock-absorbing springs, resulting in the installation assembly not having a shock-absorbing effect. Second, most of the existing mounting assemblies are not provided with shock-absorbing gaskets, resulting in the installation assembly even if a shock-absorbing spring is installed, the shock-absorbing effect is not obvious. Third, the connecting plates of the existing mounting assemblies are fixed by welding, resulting in the inability to disassemble them later. Summary of the invention

[0004] The purpose of the present invention is to provide a vertical axial flow fan installation assembly in order to solve the above-mentioned problem.

[0006] Preferably, in order to ensure that the connection between the plates is sufficiently firm, three first fixing screws are provided and are screwed at equal distances.

[0007] Preferably, in order to make the installation assembly have a certain shock-absorbing effect through the shock-absorbing spring and prevent damage to the fan due to shaking, the second fixing screw passes through the channel steel connecting plate and the channel steel and is locked by a nut, and the adapter plate is elastically connected to the channel steel through the shock-absorbing spring so that it can shrink up and down.

[0008] Preferably, in order to prevent the shock absorbing spring from rusting, the shock absorbing spring is a spring made of high-strength stainless steel, and a layer of anti-oxidation film is plated on the surface of the shock absorbing spring.

[0009] Preferably, in order to further enhance the shock absorbing effect, the shock absorbing pad is a shear rubber gasket, and its internal structure is honeycomb-shaped.

[0010] Preferably, in order to facilitate later disassembly, the channel steel is connected to the adapter plate in a quick-release manner via a second fixing screw.
