Generally, the equipment is assembled on the machine foot bracket 3, especially a horizontal compressor, and only the leftward or rightward inclination shown in fig. 1 can occur due to the torsion phenomenon generated by the rotation of the rotor component, and at this time, the vertically arranged fixing piece 4 is adopted to be combined with the horizontally arranged limiting piece, so that the rotation direction displacement of the compressor can be restrained.
For the fixing piece 4, based on the effect of resisting torsion, in order to avoid deformation, the rigidity is improved as much as possible by increasing the thickness or adding ribs and the like, so as to ensure that the reliability of the severe torsion degree of the compressor can be weakened.
In some embodiments, the limiting assembly further comprises a damping piece, and the damping piece comprises a vertical damping piece 2 and a horizontal damping piece 6; the undercarriage support 3 is characterized in that the vertical damping part 2 is arranged on the mounting seat 41, and the horizontal damping part 6 is arranged between the undercarriage support 3 and the fixing part 4.
As shown in fig. 1, in the vertical direction, the foot support 3 is connected to the mounting base 41 through the vertical vibration damping member 2 and the corresponding vertical bolt 5, the vertical bolt 5 plays a role of restraining vertical displacement, and the vertical vibration damping member 2 plays a role of damping for consuming mechanical energy of vertical vibration.

In some embodiments, the machine leg bracket 3 comprises a U-shaped groove member, and the U-shaped groove member is arranged on the mounting seat 41 in an inverted manner; the vertical vibration damping parts 2 are arranged in a plurality of distributed positions on two sides of the groove opening of the U-shaped groove component.

In some embodiments, the fixing member 4 has one end disposed on the mounting seat 41 and the other end is a free end; the limiting piece is connected to the free end.

For the bolt structure, the vertical shearing force is not born as much as possible so as not to influence the service life. Meanwhile, if the length dimension of the horizontal bolt 7 cannot meet the technological requirements, the foot pad and the bolt can be installed in a staggered mode.
For the vertical damping part 2 and the horizontal damping part 6, rubber materials with lower hardness can be adopted to improve the energy absorption capacity.
According to another aspect of the present application, there is provided a base assembly comprising a stop assembly as described above.
According to a further aspect of the present application, there is provided a compressor including the above-described limit assembly or the above-described base assembly.
The limiting assembly is applied to a compressor, particularly a horizontal compressor, namely, a tank body of the horizontal compressor is assembled on the machine foot support 3, so that the problem of large stress of a pipeline in operation and transportation experiments of the horizontal compressor can be perfectly solved.
In order to more obviously embody the beneficial effect of the novel horizontal compressor limiting structure of the application, the simulation is carried out from two working conditions of compressor operation and transportation. For example, as shown in fig. 3 and 4, compared with simulation results of operation conditions, since the operation frequency of a general air conditioner is not more than 80Hz, the comparison between 5Hz and 80Hz is performed, and it can be found that the overall reduction of the limit structure of the present application in the range of 5Hz to 80Hz is significantly lower than that of the conventional limit structure. Compare from compressor transportation operating mode again, the simulation result contrast of 1.3g of random vibration can find that this application limit structure compares and has reduced 14.7% in the biggest transportation stress of traditional limit structure pipeline.
For the limit structure of the horizontal compressor, the traditional single-stage four-foot pad has a good effect when reducing the transportation stress, but when reducing the operation stress, the torsional vibration of the compressor tank body 1 cannot be effectively weakened, so the stress of a pipeline of the compressor tank body 1 is easily over the limit value of the industrial standard due to the torsional driving of the compressor tank body 1. The middle of the double-stage eight-foot pad is connected with the four foot pads and the four foot pads, so that the fixing piece 4 of the middle metal plate has lower vertical local rigidity, the whole compressor tank body 1 has larger amplitude under the transportation working condition, and the pipeline transportation stress is easy to exceed the standard. And because the horizontal compressor generally carries out the operation experiment first, carries out the transportation experiment after, and transportation experiment stress exceeds standard, difficult rectification. Therefore, the respective disadvantages of the two traditional limiting structures are serious, and if the limiting structure is adopted, the problems can be solved at one time, and the pipeline stress of the limiting structure in the operation and transportation process can be ensured to be at a lower level.
If do not add horizontal to damping piece 6 and horizontal to bolt 7, then this structural effect is similar with the horizontal compressor of four callus on the sole of traditional single-stage, and compressor tank body 1 can produce comparatively violent torsional vibration when the operation, drives the pipeline of connecting near compressor tank body 1, and then produces great pipeline stress. If the application is adopted, if the horizontal vibration damping piece 6 and the horizontal bolt 7 are added between the machine foot bracket 3 and the fixing piece 4, during an operation test, the horizontal vibration damping piece 6 can consume torsional kinetic energy generated during the operation of the compressor tank body 1 through damping, and further pipeline stress is reduced. And in the transportation experimentation, because this limit structure is different from traditional doublestage eight callus on the sole, and 3 than traditional doublestage eight callus on the sole of undercarriage, middle mounting 4 possess higher local rigidity, so during the transportation experiment, vertical vibration amplitude can be lower, and the transportation stress of pipeline also can reduce thereupon. Can say that, the great problem of horizontal compressor operation, transportation experiment pipeline stress has been solved to the limit structure perfection of this application.
It is easily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application. The foregoing is only a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present application, and these modifications and variations should also be considered as the protection scope of the present application.
