Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of compressors, in particular to a damping foot for a compressor and the compressor. BACKGROUND

[0002] The existing compressor foot is usually composed of a foot mounting plate and a foot pad assembly. The foot mounting plate is provided with a foot pad mounting hole, and the foot pad assembly is fixed on the foot mounting plate and the mounting bottom plate of the equipment by bolts.

[0003] With the wide application of high-speed and high-power compressors, the vibration amplitude caused by inertial force and overturning force during the operation of the compressor is getting larger and larger, and the noise problem is also getting more and more serious. The existing technology usually adds elastic elements in the foot pad to absorb vibration and reduce noise. However, these elastic elements can only absorb part of the axial force generated during the operation of the compressor. In view of the increasing popularity of high-speed and high-power compressors, the damping effect of the traditional elastic foot pad is obviously insufficient. The vibration will be directly transmitted to the equipment base, further aggravating the noise problem. CONTENT OF THE UTILITY MODEL

[0004] Therefore, the purpose of the present application is to provide a damping foot for a compressor and a compressor to solve the problem that the existing compressor foot cannot effectively reduce the vibration of high-speed and high-power compressors.

[0005] According to the first aspect of the present application, a damping foot for a compressor is provided, wherein the damping foot for a compressor comprises: a first foot connected to the bottom of the compressor, the first foot comprising a first mounting plate and a first foot pad assembly; and a second foot provided at the bottom of the first foot, the second foot comprising a second mounting plate and a second foot pad assembly; the first mounting plate is connected with the second mounting plate through the first foot pad assembly, and the second mounting plate is connected with the equipment mounting plate through the second foot pad assembly.

[0006] Preferably, the first mounting plate comprises a first flat plate portion and a first inclined plate portion, the first inclined plate portion being formed at the outer periphery of the first flat plate portion; the second mounting plate comprises a second flat plate portion and a second inclined plate portion, the second inclined plate portion being formed at the outer periphery of the second flat plate portion, the second flat plate portion being parallel to the first flat plate portion, and the second inclined plate portion being parallel to the first inclined plate portion.

[0007] Preferably, the included angle between the first inclined plate portion and the first flat plate portion is 45°, and the included angle between the second inclined plate portion and the second flat plate portion is 45°.

[0008] Preferably, the first inclined plate portion and the second inclined plate portion are inclined towards the direction close to the compressor.

[0009] Preferably, the first inclined plate part and the second inclined plate part are inclined in a direction away from the compressor.

[0010] Preferably, the first foot pad assembly is provided in a plurality of numbers and arranged along a circumferential direction of the first mounting plate, and the second foot pad assembly is provided in a plurality of numbers and arranged along a circumferential direction of the second mounting plate, and the second foot pad assembly is arranged radially inward of the first foot pad assembly.

[0011] Preferably, the first inclined plate part and the second inclined plate part are connected through the first foot pad assembly, and the second plate part and the equipment mounting plate are connected through the second foot pad assembly.

[0012] Preferably, the first foot pad assembly comprises a first bolt connecting the first mounting plate and the second mounting plate, a first elastic sleeve sleeved outside the first bolt, two ends of the first elastic sleeve abutting against a bottom surface of the first mounting plate and a top surface of the second mounting plate respectively, and a first elastic ring sleeved on the first bolt, the first elastic ring being arranged on the top surface of the first mounting plate; and the second foot pad assembly comprises a second bolt connecting the second mounting plate and the equipment mounting plate, a second elastic sleeve sleeved outside the second bolt, two ends of the second elastic sleeve abutting against a bottom surface of the second mounting plate and a top surface of the equipment mounting plate respectively, and a second elastic ring sleeved on the second bolt, the second elastic ring being arranged on the top surface of the second mounting plate.

[0013] Preferably, a middle part of the first mounting plate is formed with a mounting hole, and a cylinder part of the compressor is arranged through the mounting hole.

[0014] According to the second aspect of the present application, a compressor is provided, wherein the compressor comprises the damping machine foot for the compressor as described above.

[0015] The damping machine foot for the compressor and the compressor of the present application have the first machine foot connected with the bottom of the compressor, the first machine foot comprising the first mounting plate and the first foot pad assembly. The second machine foot is arranged at the bottom of the first machine foot, and the second machine foot comprises the second mounting plate and the second foot pad assembly. The first mounting plate and the second mounting plate are connected through the first foot pad assembly, and the second mounting plate and the equipment mounting plate are connected through the second foot pad assembly. In this way, the damping machine foot is arranged in a double-layer structure, so that the vibration is preferentially transmitted to the second mounting plate, and is not directly transmitted to the equipment mounting plate. In addition, the vibration needs to pass through the first foot pad assembly and the second foot pad assembly in sequence in the process of transmission, which further hinders the transmission of the vibration, thereby effectively solving the problem that the existing machine foot of the compressor cannot effectively reduce the vibration of the high-speed and high-power compressor.

[0031] As Figures 1 to 3 indicated, a first foot 1 and a second foot 2 are provided according to the first aspect of the present application.

[0032] In the following description, reference is made to the Figures 1 to 3 The specific structure of the above components of the vibration-damping foot for compressor and the connection relationship of the above components are described in detail.

[0033] As Figures 1 to 3 indicated, in the embodiment, the first foot 1 can be connected (welded) with the bottom of the compressor. The first foot 1 can include a first mounting plate 11 and a first foot pad assembly 12. The second foot 2 can be arranged at the bottom of the first foot 1, and the second foot 2 can include a second mounting plate 21 and a second foot pad assembly 22. The first mounting plate 11 and the second mounting plate 21 can be connected through the first foot pad assembly 12 to serve as the first layer of buffer. The second mounting plate 21 and the equipment mounting plate 3 can be connected through the second foot pad assembly 22 to serve as the second layer of buffer. In this way, the vibration will pass through the first foot pad assembly 12 and the second foot pad assembly 22 in turn, and will not be directly transmitted to the equipment mounting plate 3. The two-layer buffer structure effectively hinders the transmission of vibration, thereby reducing the noise emitted by the equipment caused by the vibration of the compressor.

[0034] Preferably, as Figures 1 to 3As shown, in the embodiment, the compressor, the first foot 1, the second foot 2 and the equipment mounting plate 3 can be sequentially arranged from top to bottom. The equipment can be an air conditioner, a refrigerator or a heat pump, etc. which needs to be heat exchanged, and the equipment mounting plate 3 can be the base of the equipment. Preferably, a circular mounting hole 10 can be further formed in the center of the first mounting plate 11. Since the bottom of the compressor shell is arc-shaped, when the compressor is installed on the first foot 1, the bottom of the shell can be partially arranged in the mounting hole 10, so that the bottom surface of the shell and the surface of the first mounting plate 11 can be more closely matched to facilitate welding and fixing.

[0035] Preferably, as shown in the embodiment, Figures 1 to 3 As shown, in the embodiment, the first mounting plate 11 and the second mounting plate 21 can be coaxially arranged. A plurality of first foot pad assemblies 12 can be arranged between the first mounting plate 11 and the second mounting plate 21, i.e. the number of first foot pad assemblies 12 can be multiple. A plurality of second foot pad assemblies 22 can be arranged between the second mounting plate 21 and the equipment mounting plate 3, i.e. the number of second foot pad assemblies 22 can also be multiple.

[0036] Further, preferably, as shown in the embodiment, Figures 1 to 3 As shown, in the embodiment, the plurality of first foot pad assemblies 12 can be arranged at intervals along the circumferential direction of the first mounting plate 11, so that the plurality of first foot pad assemblies 12 can be uniformly stressed. The plurality of second foot pad assemblies 22 can be arranged at intervals along the circumferential direction of the second mounting plate 21, so that the plurality of second foot pad assemblies 22 can be uniformly stressed. Further preferably, the second foot pad assembly 22 can be arranged radially on the inner side of the first foot pad assembly 12, i.e. the second foot pad assembly 22 is closer to the central axis of the first mounting plate 11 than the first foot pad assembly 12, so that the second foot pad assembly 22 can better provide support force for the compressor.

[0037] Specifically, as shown in the embodiment, Figures 1 to 3As shown, in this embodiment, the first foot pad assembly 12 may include a first bolt 121, a first elastic sleeve 122, and a first elastic ring 123. The first bolt 121 can pass through the first mounting plate 11 and the second mounting plate 21, and locking nuts are respectively provided at the top of the first mounting plate 11 and the bottom of the second mounting plate 21, thereby connecting the first mounting plate 11 and the second mounting plate 21 by the first bolt 121. The first elastic sleeve 122 can be a cylindrical sleeve. The first elastic sleeve 122 can be fitted over the first bolt 121. Both ends of the first elastic sleeve 122 can respectively abut against the bottom surface of the first mounting plate 11 and the top surface of the second mounting plate 21 to reduce vibration transmission. The first elastic ring 123 can be fitted over the end of the first bolt 121, and the first elastic ring 123 can be located on the top surface of the first mounting plate 11 to absorb vibration and reduce noise. The first elastic sleeve 122 and the first elastic ring 123 can be made of rubber.

[0038] Similarly, such as Figures 1 to 3 As shown, in this embodiment, the second foot pad assembly 22 may include a second bolt 221, a second elastic sleeve 222, and a second elastic ring 223. The second bolt 221 can pass through the second mounting plate 21 and the equipment mounting plate 3, and locking nuts are respectively provided on the top of the second mounting plate 21 and the bottom of the equipment mounting plate 3, thereby connecting the second mounting plate 21 and the equipment mounting plate 3 by the second bolt 221. The second elastic sleeve 222 can be a cylindrical sleeve. The second elastic sleeve 222 can be fitted over the second bolt 221. Both ends of the second elastic sleeve 222 can abut against the bottom surface of the second mounting plate 21 and the top surface of the equipment mounting plate 3, respectively, to reduce vibration transmission. The second elastic ring 223 can be fitted over the end of the second bolt 221 and can be located on the top surface of the equipment mounting plate 3 to absorb vibration and reduce noise. The second elastic sleeve 222 and the second elastic ring 223 can both be made of rubber.

[0039] Preferred, such as Figure 2 As shown, in one embodiment, the upper surface of the first mounting plate 11 can be horizontally arranged, and an arc-shaped recess is formed in the middle of the upper surface of the first mounting plate 11. The recess is used to mate with the arc-shaped bottom surface of the compressor housing. The upper surface of the second mounting plate 21 can be horizontal, and the first mounting plate 11 and the second mounting plate 21 can be connected by a vertically arranged first foot pad assembly 12. The equipment mounting plate 3 can be a horizontal plate, and the second mounting plate 21 and the equipment mounting plate 3 can be connected by a vertically arranged second foot pad assembly 22, thereby forming a double-layer buffer structure to reduce the impact of vibration on the equipment.

[0040] In addition, preferred, such asFigure 1 and Figure 3 As shown in FIG. 1, in an embodiment, the first mounting plate 11 can include a first flat plate portion 111 and a first inclined plate portion 112. The first inclined plate portion 112 can be formed on the outer periphery of the first flat plate portion 111, i.e. the first inclined plate portion 112 is arranged around the first flat plate portion 111. Preferably, the first inclined plate portion 112 can be integrally formed with the first flat plate portion 111. Similarly, the second mounting plate 21 can include a second flat plate portion 211 and a second inclined plate portion 212. The second inclined plate portion 212 can be formed on the outer periphery of the second flat plate portion 211, i.e. the second inclined plate portion 212 is arranged around the second flat plate portion 211, and the second inclined plate portion 212 can be integrally formed with the second flat plate portion 211. Preferably, the second flat plate portion 211 can be parallel to the first flat plate portion 111, and the second inclined plate portion 212 can be parallel to the first inclined plate portion 112. In this case, the first inclined plate portion 112 and the second inclined plate portion 212 can be connected by the first foot pad assembly 12, and the second flat plate portion 211 and the equipment mounting plate 3 can be connected by the second foot pad assembly 22. In this way, the force transmitted from the compressor to the first foot 1 and the second foot 2 can be decomposed into radial force and axial force, thereby reducing the force transmitted to the equipment mounting plate 3, effectively reducing noise and vibration.

[0041] Further, preferably, as shown in FIG. 1, in an embodiment, the first inclined plate portion 112 and the first flat plate portion 111 can form an angle of 45°, and the second inclined plate portion 212 and the second flat plate portion 211 can form an angle of 45°. In this way, the force transmitted to the equipment mounting plate 3 can be reduced to the greatest extent. More preferably, the first inclined plate portion 112 and the second inclined plate portion 212 can be inclined towards the direction close to the compressor, i.e. as shown in FIG. 1, the outer periphery of the first mounting plate 11 and the second mounting plate 21 is inclined upwards. However, it is not limited thereto, the first inclined plate portion 112 and the second inclined plate portion 212 can also be inclined away from the compressor. In this way, the force transmitted to the equipment mounting plate 3 can also be reduced. Figure 1 and Figure 3 Further, preferably, as shown in FIG. 1, in an embodiment, the first inclined plate portion 112 and the first flat plate portion 111 can form an angle of 45°, and the second inclined plate portion 212 and the second flat plate portion 211 can form an angle of 45°. In this way, the force transmitted to the equipment mounting plate 3 can be reduced to the greatest extent. More preferably, the first inclined plate portion 112 and the second inclined plate portion 212 can be inclined towards the direction close to the compressor, i.e. as shown in FIG. 1, the outer periphery of the first mounting plate 11 and the second mounting plate 21 is inclined upwards. However, it is not limited thereto, the first inclined plate portion 112 and the second inclined plate portion 212 can also be inclined away from the compressor. In this way, the force transmitted to the equipment mounting plate 3 can also be reduced. Figure 1

[0042] In addition, as shown in FIG. 1, according to the second aspect of the present application, a compressor is provided, which comprises the vibration-reducing foot for compressor as described above. Specifically, the compressor can be a scroll compressor or a screw compressor, etc. Figures 1 to 3

[0043] ​​During use, the compressor is installed on the equipment mounting plate 3 through the damping feet for the compressor. The damping feet for the compressor have a double-layer damping structure, and the vibration of the compressor needs to pass through the first foot 1 and the second foot 2 in sequence during transmission, thereby avoiding direct transmission of the vibration to the equipment mounting plate 3. In addition, the outer periphery of the first mounting plate 11 and the second mounting plate 21 is inclined, so that the force transmitted by the compressor to the first foot 1 and the second foot 2 can be decomposed into radial force and axial force, thereby reducing the force transmitted to the equipment mounting plate 3, thereby effectively reducing noise and vibration.
