Generally, the equipment is assembled on the machine foot bracket 3, especially a horizontal compressor, and only left or right inclination as shown in fig. 1 can occur due to the torsion phenomenon generated by the rotation of a rotor component, and at the moment, the vertically arranged fixing piece 4 is combined with the horizontally arranged limiting piece to restrain the rotation direction displacement of the compressor.
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 the reliability of weakening the severe torsion degree of the compressor.

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. And then comparing the transportation working conditions of the compressor, comparing the simulation results of randomly vibrating 1.3g, and finding that the maximum transportation stress of the pipeline of the limiting structure is reduced by 14.7 percent compared with that of the traditional limiting structure.
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 eight callus on the sole of doublestage is because four callus on the sole and four callus on the sole down are connected in its middle, so the vertical local rigidity that is lower to of mounting 4 of middle panel beating, and whole compressor jar body 1 has great amplitude when the transportation operating mode, and pipeline transportation stress exceeds standard easily. And because the horizontal compressor generally carries out the operation experiment at first, carries out the transportation experiment afterwards, and transportation experiment stress is off-standard, and difficult rectification is improved. 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 the horizontal vibration damping piece 6 and the horizontal bolt 7 are not added, the structural effect is similar to that of the traditional single-stage four-foot-pad horizontal compressor, and the compressor tank body 1 can generate severe torsional vibration during operation to drive a pipeline connected to the position near the compressor tank body 1, so that large pipeline stress is generated. 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. It can be said that, the great problem of horizontal compressor operation, transportation experiment pipeline stress has been perfectly solved to the limit structure 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.
