For ease of description and understanding of this embodiment, the centrifugal compressor housing is referred to herein as the object, and in fact, in this or other embodiments, the object includes not only a centrifugal compressor housing, but also other objects that are provided with flanges of different diameters on both sides.

The portable tool comprises a first side beam 10 and a second side beam 20, the first side beam 10 and the second side beam 20 are oppositely arranged, the first side beam 10 is provided with a first supporting piece 11, the first supporting piece 11 is provided with a first supporting surface, the second side beam 20 is correspondingly provided with a second supporting piece 21, the second supporting piece 21 is provided with a second supporting surface, and the height of the first supporting surface relative to the horizontal plane is lower than the height of the second supporting surface relative to the horizontal plane, so that the first supporting piece 11 and the second supporting piece 21 can be matched to support the centrifugal compressor shell. For convenience of description, the following heights refer to heights compared to a horizontal plane unless otherwise specified. The first support surface is a contact surface of the first support 11 with the object when the object is supported.

Specifically, the height difference between the first supporting member 11 and the second supporting member 21 may be the height difference between the diameters of the flanges on both sides of the casing of the centrifugal compressor of a certain specification, or may be the average value of the height differences between the diameters of the flanges on both sides of the casing of the centrifugal compressor of a plurality of specifications, so as to support the centrifugal compressors of different specifications. The present application is not particularly limited, and those skilled in the art can set the application according to actual requirements.

Referring to fig. 1 and 2, in one embodiment, the first support 11 includes a plurality of first support shafts 111, the first support shafts 111 are disposed at intervals along the length direction of the first side member 10, and the second support 21 includes a plurality of second support shafts 211, the second support shafts 211 are disposed at intervals along the length direction of the second side member 20. The plurality of first support shafts 111 and the plurality of second support shafts 211 may be mounted in the following manner: the first support beam is provided with a first cavity 13 through which the first support shaft 111 is inserted, and the second support beam is provided with a second cavity 23 through which the second support shaft 211 is inserted, but is not limited thereto.

The planes of the first support shafts 111 together form a first support surface, and the planes of the second support shafts 211 together form a second support surface, and the height of the lowest point of the first support surface is lower than that of the lowest point of the second support surface. In the present embodiment, in order to support the centrifugal compressor housing, when the number of the first support shafts 111 is greater than two, the first support surfaces are arc surfaces, and when the number of the second support shafts 211 is greater than two, the second support surfaces are arc surfaces as well. In other embodiments, the first supporting surface and the second supporting surface may be selectively configured to be a plane or an arc according to an object actually supported. In this embodiment, the number of the first support shafts 111 and the second support shafts 211 is two, so after the arrangement, the first support surfaces and the second support surfaces are all planes, and only two first support shafts 111 and two second support shafts 211 are needed to reduce the weight of the tool body, so that the tool is convenient for carrying by operators.

Further, the first support shafts 111 are provided with first bearing rollers, and the second support shafts 211 are provided with second bearing rollers 212, so that the centrifugal compressor housing can rotate on the first support shafts 111 and the second support shafts 211, thereby facilitating cleaning and maintenance of the centrifugal compressor housing.

With continued reference to fig. 1 and 2, in one embodiment, the first supporting member 11 is provided with at least two groups, the first supporting surfaces are correspondingly formed with two first supporting surfaces, and one of the at least two second supporting surfaces is higher than the other of the at least two supporting surfaces, in other words, the at least two first supporting surfaces are different from each other in height, and each of the at least two first supporting surfaces is lower than the second supporting surface in height, so that the second supporting surfaces form at least two height differences with the at least two first supporting surfaces, thereby facilitating supporting the centrifugal compressor housings of different specifications. Specifically, according to the difference of the heights of two sides of the centrifugal compressor shell, different first supporting surfaces and second supporting surfaces can be selected to be manufactured, for example, 3 first supporting surfaces are divided into a high first supporting surface, a medium first supporting surface and a short first supporting surface according to the heights, and the centrifugal compressor shell can select any one first supporting surface according to requirements and is matched with the second supporting surface to support.

In one embodiment, the second supporting members 21 are provided with at least two groups, two second supporting surfaces are correspondingly formed, and the height of one of the at least two second supporting surfaces is larger than the height of the other of the at least two supporting surfaces, in other words, the heights of the at least two second supporting surfaces are different, so that the centrifugal compressor housings with different specifications can be supported conveniently. For example, the number of the second supporting surfaces is 3, and the centrifugal compressor shell is divided into a high second supporting surface, a medium second supporting surface and a short second supporting surface according to the height, and the first supporting surface and any one of the second supporting surfaces can be selected for supporting according to the requirements.
