The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The utility model discloses an embodiment of impeller support frock, as shown in fig. 1, including the supporting part 1 that is used for bearing impeller to and be used for supporting part 2 of supporting part 1, supporting part 1 sets up at 2 tops of supporting part and has the bearing face that is suitable for with the impeller contact, at the in-process that carries out the bearing to the impeller, carries out the bearing in the face of the blade with the impeller through the bearing to this avoids the operation personnel to get into during operation under the wheel hub of impeller, and the blade drops from supporting the frock. The bottom of supporting part 2 still is equipped with base 3, because the impeller is installed in comparatively remote area usually, consequently, when installing at the scene, local geological conditions is more complicated, and support the impeller for can be better, the in-process impeller of avoiding supporting drops from supporting portion 1, consequently need handle the place when the operation in advance and level, guarantee to support placing in the operation place that the frock can be stable with this, avoid supporting the frock itself and just take place the slope when settling. When the supporting tool cannot be kept flat when being arranged, at the moment, when the supporting part 1 supports the blades of the impeller, a certain inclination angle possibly generated between the blades of the impeller and the supporting part 1 is formed, namely, the contact area between the impeller and the supporting part 1 is reduced at the moment, but the pressure of the whole impeller on the supporting part 1 cannot be randomly reduced, so that the pressure applied to the part, in contact with the blades of the impeller, of the supporting part 1 is increased, and the part of the supporting part 1 is easily deformed or the blade part of the impeller is easily damaged in the past.

In addition, one or more supporting tools can be arranged below the blades of each impeller, and in order to control the same pressure of the supporting tools below each impeller, the phenomenon that the service life of the supporting tools below a certain impeller is greatly reduced due to overlarge pressure of the supporting tools is avoided, and therefore the arrangement positions of the supporting tools need to be controlled. For example, when a support tool is arranged under each impeller, the impeller needs to be lifted by a main crane and an auxiliary crane, when the lifting height of the impeller reaches about 1 meter, the support tool under each impeller blade can be carried to a position 1.5 meters away from the blade root of each blade, then the crane is controlled to slowly put down the impeller until a plurality of blades of the impeller are completely abutted against the bearing part 1 of the support tool, at the moment, because the field is flattened in advance, each blade of the impeller can be completely abutted against the bearing surface of the bearing part 1, namely, at the moment, the bearing part 1 of each support tool can uniformly distribute the pressure generated by each blade on the bearing part 1, so that each bearing part 1 can uniformly bear the pressure generated by the impeller, the pressure born by a certain part of the bearing part 1 is avoided from being too large, the bearing part 1 is uniformly stressed on the whole bearing part 1, and the huge difference between each part of the bearing part 1 is ensured, therefore, the problem that the service life of one supporting tool is influenced due to overlarge pressure is avoided. And, because the place is level and smooth, support the frock and can stably place in the operation place, consequently carrying out the in-process of bearing to the blade of impeller, can keep relative stability with the impeller for thereby the impeller can not drop therefrom and produce the risk of whereabouts.

In order to better support the impeller, the base 3, the bearing part 1 and the supporting part 2 are welded and fixed, so that the overall strength of the supporting tool is ensured, and the cracking of the joint of the supporting tool after the supporting tool is stressed by the impeller is avoided. And, the supporting part 1, the supporting part 2 and the base 3 are all carbon structural steel parts, and because the carbon structural steel parts have pure steel quality, less impurities and good mechanical properties, and can bear larger gravity, the impeller with larger weight can be manufactured by using the supporting tool made of the carbon structural steel, and the overall strength of the supporting tool can be further improved.
