[0047] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0048] Figure 1-Figure 5 FIG. 1 shows a structural diagram of a vibration reduction device 100 according to an embodiment of the present application. Figure 1-Figure 5 As shown, the vibration reduction device 100 may include:

[0049] The embodiment of the present application provides a reactor vibration reduction device 100, comprising:

[0050] A base 110, on which the reactor is mounted;

[0051] A plurality of first vibration reduction assemblies 120, one end of each of the plurality of first vibration reduction assemblies 120 is connected to the base 110, and one end of each of the plurality of first vibration reduction assemblies 120 away from the base 110 is installed on the floor so that the base 110 does not contact the floor;

[0052] The second vibration damping assembly 130 is installed on the first vibration damping assembly. When the first vibration damping assembly 120 is damping vibration, the second vibration damping assembly 130 contracts to assist the first vibration damping assembly 120 .

[0053] In this embodiment, when the reactor is in use, the first vibration reduction assembly 120 contracts to absorb the vibration generated by the base 110. When the first vibration reduction assembly 120 contracts, the second vibration reduction assembly 130 supports the first vibration reduction assembly 120 and reduces the vibration of the first vibration reduction assembly 120, thereby improving the absorption of the vibration of the base 110, so that the force generated by the vibration of the reactor is added to the first vibration reduction assembly 120 and the second vibration reduction assembly 130, and the reactor directly contacts the floor to generate noise;

[0054] At least four groups of first vibration reduction components 120 are provided, which are respectively installed at the four corners of the base 110. The base 110 is lifted by the first vibration reduction components 120, and the reactor is installed on the base 110, so that the vibration force of the reactor acts on the first vibration reduction component 120, and the vibration force is absorbed by the first vibration reduction component 120 and the second vibration reduction component 130, so as to avoid the reactor directly contacting the floor, causing the vibration force to be directly transmitted to the floor, thereby reducing the spread and generation of noise;

[0055] It should be noted that when assembling the first vibration damping assembly 120, a pit with a depth of about ten centimeters can be dug on the floor according to the size of the upper surface of the base 110. After the first vibration damping assembly 120 is installed at the four corners of the pit, the base 110 and the four first vibration damping assemblies 120 are installed.

[0056] like Figure 1-Figure 4 As shown, in one embodiment,

[0057] The first vibration reduction assembly 120 includes:

[0058] Two shells 121, the two shells 121 are connected to the base 110 and the floor respectively, each shell 121 is provided with two cavities 1211 and a slide groove 1212, and the cavities 1211 on the corresponding sides are connected to the slide groove 1212;

[0059] Slide bars 122, the number of which corresponds to the number of cavities 1211, the slide bars 122 are mounted on the housing 121, and the slide bars 122 are located in the cavities 1211;

[0060] Slide blocks 123, the number of the slide blocks 123 corresponds to the number of the slide bars 122, and the slide blocks 123 are slidably connected to the corresponding slide bars 122;

[0061] Two support rods 124, the two support rods 124 are cross-arranged, and the two ends of the two support rods 124 are rotatably connected to the corresponding sliders 123, and the connection between the support rods 124 and the sliders 123 is located in the slide groove 1212;

[0062] The first spring 125 , the number of the first springs 125 corresponds to the number of the sliders 123 , one end of the first spring 125 is connected to the slider 123 , and the other end is connected to the housing 121 , and the first spring 125 is sleeved on the slide bar 122 .

[0063] In this embodiment, when the base 110 is vibrated, the distance between the two shells 121 is shortened, and the two ends of the two support rods 124 slide correspondingly, so that the slider 123 moves along the slide rod 122, so that the first spring 125 contracts, forming a certain support for the two shells 121. At the same time, the first spring 125 releases a repulsive force with the vibration of the base 110, which offsets the force generated by the vibration of the reactor, thereby avoiding the direct contact between the reactor and the floor to generate noise.

[0064] Furthermore,

[0065] A through hole 1241 is provided on one of the support rods 124 for the other support rod 124 to rotate, and a rotating shaft is installed at the connection of the two support rods 124. The two support rods 124 are arranged in an "X" shape, and one support rod 124 passes through the other support rod 124, and the passed support rod 124 has a hole for the passed support rod 124 to rotate. The two support rods 124 rotate through the rotating shaft. When the two shells 121 move, the sliders 123 on both ends of the two support rods 124 slide along the slide rod 122 to shrink the first spring 125.

[0066] It should be noted that the thickness of the support rod 124 with the through hole 1241 is greater than the thickness of the other support rod 124 , so that the support rod 124 can pass through the support rod 124 with the through hole 1241 .

[0067] Furthermore, the two support rods 124 can also be directly connected by a rotating shaft. In this case, the slide grooves 1212 on the two housings 121 are provided with a certain degree of misalignment to ensure that when the housings 121 are close to each other, the support rods 124 can well drive the slider 123 to move.

[0068] When one of the support rods 124 passes through another support rod 124, a through hole 1241 needs to be provided on the passed support rod 124 to ensure that the two support rods 124 can rotate around the rotation axis;

[0069] The stiffness of the first spring 125 reaches 2.244-2.898 kN / mm, and the rated load that can be borne can reach 25.9 tons.

[0070] like Figure 2-Figure 4 As shown, in one embodiment,

[0071] The positions of the slide grooves 1212 on the same side of the two shells 121 are adapted to each other.

[0072] In this embodiment, the positions on the slide grooves 1212 are adapted. When one support rod 124 passes through the through hole 1241 and is connected to another support rod 124, the positions of the slide grooves 1212 are located on the same plane. When the two support rods 124 are overlapped, the two slide grooves 1212 are staggered, and the two slide grooves 1212 on the same side are not located on the same plane.

[0073] like Figure 4 As shown, in one embodiment,

[0074] The first vibration reduction assembly 120 further includes:

[0075] The limiting rod 126 , the number of which matches the number of the sliding rods 122 , is mounted on the housing 121 , and the limiting rod 126 is located in the cavity 1211 , and the sliding block 123 is slidably sleeved on the limiting rod 126 .

[0076] In this embodiment, the limit rod 126 is arranged parallel to the slide rod 122, and the slider 123 is sleeved on the limit rod 126 and the slide rod 122. When the support rod 124 moves, the slider 123 slides laterally along the slide rod 122. At the same time, the limit rod 126 plays a certain limiting role on the movement trajectory of the slider 123.

[0077] like Figure 3-Figure 4 As shown, in one embodiment,

[0078] The second vibration reduction assembly 130 includes:

[0079] A telescopic rod 131, two ends of which are respectively connected to the two housings 121;

[0080] The second spring 132 is sleeved on the telescopic rod 131 , and two ends of the second spring 132 are respectively connected to the two housings 121 .

[0081] In this embodiment, when the two shells 121 move toward each other, the contraction rod contracts and the second spring 132 contracts to generate a repulsive force to tightly support the two shells 121, and cooperate with the first spring 125 to support the shell 121, so that the first vibration reduction assembly 120 and the second vibration reduction assembly 130 absorb the vibration of the reactor to prevent the reactor from directly contacting the floor and generating noise. The second spring 132 has the same stiffness as the first spring 125, reaching 2.244-2.898 kN / mm, and can withstand a rated load of up to 25.9 tons.

[0082] like Figure 5 As shown, only one cavity 1211 may be provided on the shell 121, and the two shells 121 may be damped by a support rod 124. When the first damping assembly 120 is provided with only one support rod 124, one end of the telescopic rod 131 is connected to the shell 121, and the other end is connected to the base 110 or the ground, so that the shell 121, the support rod 124 and the telescopic rod 131 form an inverted "N"-shaped structure. At this time, when the base 110 vibrates, the shell 121 moves to make the support rod 124 push the slider 123 to slide along the slide rod 122, and at the same time the telescopic rod 131 contracts, so that the first spring 125 and the second spring 132 contract at the same time to absorb the vibration.

[0083] like Figure 1-Figure 2 As shown, in one embodiment,

[0084] Both sides of the base 110 are connected with protrusions 111 , and the housing 121 located on the upper side is connected to the protrusions 111 .

[0085] In this embodiment, the cross-section of the base 110 and the protrusion 111 is “T”-shaped, the upper shell 121 contacts the protrusion 111 on the side of the base 110 , and the lower shell 121 is connected to the floor.

[0086] like Figure 1-Figure 2 As shown, in one embodiment,

[0087] A bracket 112 is laterally connected to the base 110 , and the reactor is mounted on the bracket 112 .

[0088] In one embodiment,

[0089] The upper shells 121 are all located on the same horizontal plane.

[0090] In this embodiment, the upper shell 121 is located on the same horizontal plane to ensure that after the first vibration reduction assembly 120 is installed, the base 110 is located on a horizontal plane, thereby ensuring that the reactor is installed horizontally.
