Description
Technical Field
[0001] The utility model belongs to the technical field of mechanical equipment vibration reduction, and in particular relates to a mechanical equipment vibration reduction device. Background Art
[0002] Shock absorbers are very important components in modern mechanical equipment. They are mainly used to reduce or eliminate mechanical vibration and impact to protect mechanical equipment and extend its service life, while reducing noise and improving work efficiency. In many mechanical equipment, such as engines, motors and other rotating equipment, there are vibration problems. These vibrations may be caused by imbalance of rotating parts, bearing failure, structural defects or other reasons. Through its special structure and materials, the shock absorber can absorb and consume these vibration energies, thereby reducing the overall vibration level of the equipment. However, there is a problem in the existing shock absorber device of mechanical equipment, that is, the straight-through structure between the charging and discharging port of the damper cylinder and the cylinder easily causes the gas to overflow and escape from the cylinder sealing port when the internal air pressure of the cylinder is too high. This not only reduces the vibration reduction effect of the shock absorber, but may also cause damage to the equipment and shorten its service life. Utility Model Content
[0003] In order to overcome the problem that the existing mechanical equipment shock absorber device has a straight-through structure between the filling and discharging port of the damper cylinder and the cylinder, the gas is easily overflowed and escaped from the cylinder sealing port when the internal air pressure of the cylinder is too high.

[0005] Preferably, the cylinder is sealed by a sealing cover, and the anti-return airway film at the lower end of the airway film rod is used to block the lower port of the airway, thereby effectively preventing the air pressure in the cylinder from being too high when the damping piston rod moves in the damping chamber, causing the gas to overflow directly from the port where the sealing cover is connected. This solves the problem of existing mechanical equipment shock absorber devices, because the filling and discharging ports of the damper cylinder are through structures with the cylinder, which causes the gas to easily overflow and escape from the sealing port of the cylinder when the air pressure inside the cylinder is too high.
[0006] Preferably, a spring base is arranged on the outer side of the damping piston rod, and the spring base and the damping piston rod are integrally formed; a spring is sleeved on the outer side of the damping cavity, and the spring is fixedly arranged in contact with the spring base.

[0008] Preferably, a connecting shaft is provided at the upper end of the damping cavity and the lower end of the spring base, and the connecting shaft, the damping cavity and the spring base are integrally formed.
[0009] Preferably, the air storage assembly includes a cylinder, an air pressure sensor, a sealing cover, an airway membrane rod, and a non-return airway membrane; a cylinder is arranged on one side of the damping cavity, and the cylinder is connected to the internal airway of the damping cavity.
[0010] Preferably, a sealing cover is provided at the upper end of the cylinder, and the sealing cover is threadedly sealed with the port of the cylinder; an airway membrane rod is provided at the lower end surface of the sealing cover, and the airway membrane rod is inserted into the airway below the sealing cover; a non-return airway film is provided at the lower end of the airway membrane rod, and the non-return airway film and the airway membrane rod are integrally formed, and the non-return airway film is provided below the lower end port of the airway where the airway membrane rod is located, and while the cylinder is sealed by the sealing cover, the non-return airway film at the lower end of the airway membrane rod is used to block the lower end of the airway, thereby effectively preventing the air pressure in the cylinder from being too high when the damping piston rod moves in the damping cavity, resulting in the problem of gas directly overflowing from the port at the connection of the sealing cover.
[0011] Preferably, an air pressure sensor is disposed inside the lower end surface of the cylinder, and the detection end of the air pressure sensor is disposed inside the cylinder. The air pressure sensor monitors the air pressure inside the cylinder in real time, thereby effectively improving the safety of monitoring air pressure changes in the cylinder.
[0012] Beneficial effects of the utility model:
[0013] 1. The existing mechanical equipment shock absorber device has a straight-through structure between the filling and discharging port of the damper cylinder and the cylinder, which leads to the problem that when the internal air pressure of the cylinder is too high, the gas is easy to overflow and escape from the cylinder sealing port; while the cylinder is sealed by the sealing cover, the anti-return airway film at the lower end of the airway film rod is used to block the lower port of the airway, thereby effectively preventing the problem that the air pressure in the cylinder is too high when the damping piston rod moves in the damping cavity, causing the gas to directly overflow from the port at the connection of the sealing cover; the existing mechanical equipment shock absorber device solves the problem that when the internal air pressure of the cylinder is too high, the gas is easy to overflow and escape from the cylinder sealing port because the filling and discharging port of the damper cylinder and the cylinder are straight-through structures;
