Description

Technical Field

[0001] The present invention relates to the technical field of vibration devices, and particularly to a balloon-type passive compensation three-dimensional vibration damping device. Background Art

[0002] Vibration damping devices are widely used in many industrial fields such as industrial and mining enterprises, construction, and transportation. Currently, vibration damping devices are divided into passive damping, active compensation, and combined main-passive vibration damping systems. Passive damping vibration reduction does not require external energy input and relies on physical structures (such as elastic materials, dampers, mechanical suspensions) to absorb or dissipate vibration energy. By inertial balance, friction energy dissipation, or material deformation, the sensitivity of the system to external disturbances is reduced. Passive vibration reduction mainly reduces the amplitude and frequency of vibration, and the vibration reduction effect is not ideal. Active compensation vibration reduction monitors vibration in real time through sensors and drives actuators (such as motors, piezoelectric ceramics, oil pumps, air pumps) to generate counteracting forces to offset disturbances, but it requires external energy and closed-loop control. For the installation of sensors and other monitoring equipment in special fields such as high-speed railways and power, traditional vibration dampers are difficult to meet the actual needs under the conditions of both requiring sufficient vibration reduction and restricting external energy sources.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figures 1-4 The present invention provides an airbag type passive compensation three-dimensional vibration reduction device, comprising:

[0025] A vibration reduction component 1 8, a vibration reduction component 2 9, a vibration reduction component 3 10 and a vibration reduction component 4 11;

[0026] A support plate 14 is fixedly connected between the vibration reduction component 1 8 and the vibration reduction component 2 9 , the vibration reduction component 3 10 is fixedly connected to the support plate 14 , and the vibration reduction component 4 11 is fixedly connected to the vibration reduction component 3 10 .

[0027] The vibration reduction component 1 8, the vibration reduction component 2 9, the vibration reduction component 3 10 and the vibration reduction component 4 11 constitute a vibration reduction device with a three-dimensional vibration reduction function. The vibration reduction component 1 8 and the vibration reduction component 2 9 are vertically arranged on both sides of the support plate 14, the vibration reduction component 3 10 is horizontally arranged on the support plate 14, and the vibration reduction component 4 11 is horizontally arranged on the vibration reduction component 3 10; when the vibration reduction component 4 11 is subjected to vertical movement, the vibration reduction component 4 11 and the vibration reduction component 3 10 can perform vibration reduction in the vertical direction, and when subjected to horizontal movement, the vibration reduction component 1 8 and the vibration reduction component 2 9 can perform vibration reduction in the horizontal direction.

[0028] For a further optimized solution, the vibration damping components 1, 2, 3, and 4 have the same structure. The vibration damping component 1 includes a U-shaped inertia block 1, a U-shaped follower housing 2, a U-shaped airbag 1, a U-shaped airbag 2, and a bearing plate 12. Both the U-shaped airbag 1 and the U-shaped airbag 2 have two arms. One arm of the U-shaped airbag 1 is fixedly connected inside the U-shaped inertia block 1, and the other arm of the U-shaped airbag 1 is fixedly connected between the U-shaped inertia block 1 and the U-shaped follower housing 2. One arm of the U-shaped airbag 2 is fixedly connected inside the U-shaped inertia block 1, and the other arm of the U-shaped airbag 2 is fixedly connected between the U-shaped inertia block 1 and the U-shaped follower housing 2. The bearing plate 12 is fixedly connected between the U-shaped airbag 1 and the U-shaped airbag 2. The bearing plate 12 is located inside the U-shaped inertia block 1, and the U-shaped inertia block 1 is fixedly connected with a counterweight 3.

[0029] One arm of each of the U-shaped airbag 1 and the U-shaped airbag 2 is fixedly connected inside the U-shaped inertia block 1, and there is one arm of the U-shaped airbag 1 and the U-shaped airbag between the U-shaped inertia block 1 and the U-shaped follower housing 2 respectively, which can better play the role of vibration damping.

[0030] Refer to Figures 2-3 For example, when the U-shaped follower housing 2 moves from right to left, since the U-shaped follower housing 2 squeezes the U-shaped inertia block 1, the U-shaped airbag 2 is in a high-pressure state, and the U-shaped airbag 1 is in a low-pressure state. At this time, the left side of the bearing plate 12 has high air pressure and the right side has low air pressure, and the bearing plate 12 receives a force from left to right. Thus, when the U-shaped inertia block 1 follows the movement of the U-shaped follower housing 2, a reverse push will be generated on the bearing plate 12, greatly increasing the vibration damping effect.

[0031] For a further optimized solution, the bearing plate 12 of the vibration damping component 1 is fixedly connected with the support plate 14, and the bearing plate 12 of the vibration damping component 2 is fixedly connected with the support plate 14.

[0032] Both ends of the support plate 14 are fixedly connected with the bearing plate 12, connecting the vibration damping component 1 and the vibration damping component 2 together.

[0033] For a further optimized solution, the U-shaped follower housing 2 of the vibration damping component 3 is fixedly connected to the support plate 14.

[0034] For a further optimized solution, a connecting block 1 is fixedly connected to the bearing plate 12 of the vibration damping component 3, and the U-shaped follower housing 2 of the vibration damping component 4 is fixedly connected to the connecting block 1.

[0035] When arranging the vibration damping components 3 and 4, the two U-shaped follower housings are arranged in a cross shape in the horizontal direction. Refer to Figure 1 , which can meet the vibration damping requirements in more directions.

[0036] For a further optimized solution, a second connecting block 15 is fixedly connected to the bearing plate 12 of the vibration damping assembly IV 11, and a storage platform 7 is fixedly connected to the second connecting block 15.

[0037] The storage platform 7 is used for placing objects.

[0038] For a further optimized solution, inflation nozzles 5 are installed on both the first U-shaped airbag 4 and the second U-shaped airbag 6.

[0039] The inflation nozzles 5 facilitate inflation.

[0040] The sum of the masses of the U-shaped inertia block 1 and the counterweight 3 should be equal to the sum of the masses of the storage platform 7 and the placed objects.
