Vibration damping device and air-conditioning equipment

Abstract

The invention relates to a vibration damping device and air-conditioning equipment. The vibration damping device comprises a vibration damper (3) arranged between a part to be subjected to vibration damping, and an installation support (4), and a limit support (2) connected with the installation support (4), and used for limiting the vibration amplitude of the vibration damper (3) in a vibration damping direction from being not greater than a preset use safety value, and the limit support (2) and the installation support (4) have movement allowance at the junction. The vibration damping deviceis capable of limiting the vibration amplitude of the vibration damper in the vibration damping direction from being not greater than the preset use safety value, large change of the vibration amplitude of the vibration damper is avoided even if in the case of uneven road condition in a transport process, and damage to the vibration damper is prevented, so that the safety of the part to be subjected to vibration damping in the transport process is ensured. Moreover, in the running process of the equipment, the limit support and the installation support have the movement allowance at the junction, so that the vibration damper is still capable of exerting the vibration damping effect without the need of detaching the limit support, the use convenience is improved, and the vibration dampingneeds of the equipment in the transport process and the running process are considered.

Description

technical field [0001] The invention relates to the technical field of vibration reduction, in particular to a vibration reduction device and an air conditioner. Background technique [0002] The spring damper is widely used in the vibration isolation of the fan parts of the fresh air unit because of its good vibration damping performance. In the existing spring damper, the spring is generally inserted into the cylindrical base to absorb the vibration along the up and down direction during the movement of the fan parts. [0003] However, since this kind of spring damper is not equipped with a limit device, during the transportation of the fresh air unit, due to uneven road conditions, etc., the spring damper will be passively shaken, and the shaking force with an uncertain direction will easily lead to a large spring amplitude. Large changes, causing the spring to easily come out of the base, which may cause damage to the fan parts during transportation. [0004] Moreover,...

Problems solved by technology

[0003] However, since this kind of spring damper is not equipped with a limit device, during the transportation of the fresh air unit, due to uneven road conditions, etc., the spring damper will be passively shaken, and the shaking force with an uncertain direction will easily lead to a large spring amplitude. large variations, causing the springs to tend to come out of the base, which could lead to damage to fan components during transport

[0004] Moreover, after the spring comes out of the base during transportation, it is difficult to find out in time. The spring shock absorber will not be able to play the original vibration isolation function during the operation of the fresh air unit, which will affect the reliability and service life of the fan components.

[0005] In order to solve this problem, the spring damper is provided with a limit device in the prior art, so as to completely limit the freedom of movement of the spring damper during the transportation of the fresh air unit, and prevent the spring from falling out of the base.

During the operation of the fresh air unit, the limit device needs to be removed so that the spring shock absorber can play the role of vibration isolation. However, the internal space of the fresh air unit is small, and it is difficult to remove the limit device conveniently.
