In order to better understand the present invention, an auxiliary device for a generator unit according to an embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 8 .

Please refer to Figure 1, Figure 2 and Figure 3 together. FIG. 1 shows a perspective view of the auxiliary device 100 installed with a generator unit 200 ; FIG. 2 shows a perspective view of the auxiliary device 100 installed with a generator unit 200 .

Considering the convenience of transportation, the large-size generator can be designed as a plurality of generator units 200 independent of each other, and a complete generator can be formed by splicing two generator units 200, or three or four or more Generator units 200 are spliced together. In order to more clearly describe the installation and layout position of the generator unit 200 on the auxiliary device 100, the surface formed by the outer contour of the generator unit 200 is divided into a circular arc surface 201, an upper end surface 202, a lower end surface 203 and two side surfaces. The end face 204 is described. Specifically, the generator unit 200 includes an arc surface 201 parallel to the generator height direction, an upper end surface 202 and a lower end surface 203 perpendicular to the generator height direction, and two side end surfaces 204 parallel to the generator height direction. The generator unit 200 may be a generator stator unit or a generator rotor unit.

Taking the generator unit 200 as a generator rotor unit and the generator rotor being spliced by two generator rotor units as an example, the technical solutions of the embodiments of the present invention will be described in detail below.

The embodiment of the present invention proposes an auxiliary device 100 for a generator unit 200, including: a base 11; a fixed platform 13, which is arranged on the base 11 through a support base 12, and two In the generator unit 200 above, more than two generator units 200 are fixed on the upper end surface 202 , the lower end surface 203 or the side end surface 204 on the fixed platform 13 .

Exemplarily, the fixed platform 13 is used to respectively fix two generator units 200, and the upper end surface 202 or the lower end surface 203 of the two generator units 200 are fixed on the fixed platform 13 close to the fixed platform 13 and spaced apart; or, two The generator unit 200 is fixed on the fixed platform 13 with the end faces 204 on both sides approaching and spaced apart. Wherein, the overall height and/or overall width of the two fixed generator units 200 are smaller than the diameter of the generator units. Such an arrangement can reduce the width of transportation, effectively solving the problem of difficult transportation of large-sized generators.

Specifically, the base 11 is mainly used to carry other components of the auxiliary device 100 and the generator rotor unit, and may be a frame structure surrounded by a plurality of strip beam structures with a certain thickness. In order to improve the strength and The bearing capacity can also be enclosed by multiple plate structures with a certain thickness. In order to ensure the strength, the base 11 can be made of metal materials, such as iron, steel and so on.

The fixed platform 13 is provided with a fixing part for fixing the generator rotor unit, so that the two generator rotor units can be stably fixed on the fixed platform. 13 on. Specifically, the fixing part may be a threaded hole opened on the fixing platform 13, which corresponds to the flange hole or the reinforcing structure 207 hole or the mounting hole 206 after the generator rotor unit is placed on the fixing platform 13, and is fastened with bolts or the like. Fasten the parts through the holes. Of course, the fixing part is not limited to this structure, for example, it can also be a slot, a buckle and other structures, as long as the generator rotor unit can be stably fixed on the fixing platform 13 . Exemplarily, a groove adapted to the end face of the generator rotor unit may be formed on the fixing platform, and the generator rotor unit is placed in the groove to achieve fixing. The structure of the fixing table 13 is also not limited, and it can be circular or other irregular shapes, as long as it has a certain area and can support the generator rotor unit.

In order to shorten the width requirements of the transportation equipment during transportation, as shown in Figure 2, the upper end surface 202 or the lower end surface 203 of the two generator rotor units on the fixed platform 13 is close to the fixed platform 13 and fixed at intervals. The opening directions of the arc surfaces 201 of the machine rotor unit are basically the same, and the centers of the arc surfaces 201 are basically in the same plane. Such an arrangement can reduce the width of transportation to half of the original, effectively solving the problem of difficult transportation of large-sized generators.

Of course, the two generator rotor units can also be arranged on the fixed platform 13 with the end surfaces 204 on both sides approaching and fixed at intervals, wherein the opening directions and heights of the arc surfaces 201 of the two generator units 200 are basically the same . This can be vividly described as buckling two semicircular generator rotor units side by side or in a row on the fixed table assembly 131 like two arched doors. Such an arrangement can change the width of transportation from the diameter of one generator to the height of one generator or the height of two generators, and also effectively solves the problem of difficult transportation of large-sized generators.

A groove 1211 is defined at the lower end of the sliding part 121 , and the sliding part 121 is connected to the track 111 through the groove 1211 , so that the support base 12 can drive the fixed table assembly 131 to move along the track 111 . The groove 1211 here can be a trapezoidal groove 1211 or a rectangular groove 1211 or a triangular groove 1211 or an arc groove 1211, and the section along the length direction of the track 111 corresponds to the structure of the groove 1211 of the sliding part 121, so that the sliding part 121 It can smoothly cooperate with the track 111 to complete relative movement. Of course, the sliding part 121 can also be provided with protrusions 1111 , and the track 111 can be provided with corresponding grooves 1211 , as long as the stable connection and movement between the sliding part 121 and the track 111 can be realized.

Each set of support parts 122 includes at least two support members. The supporting part 122 corresponds to a group of sliding parts 121, and a group of sliding parts 121 may be one sliding part, or may be multiple independent sliding parts.

Specifically, balls are provided on the surface of the groove 1211 or the surface of the protrusion 1111 where the sliding part 121 and the track 111 are in contact with each other, and the support seat 12 is rollingly connected with the track 111 through the balls. The balls can also be rollers. Friction is further reduced by rolling connections. Certainly, the sliding part 121 and the track 111 may also adopt a sliding friction method, which will not be repeated here.

Here, the connecting piece 142 can be integrally formed, or can be formed by connecting multiple parts, for example, the top surface 1421 and the bottom surface 1422 can be welded to the main body of the connecting piece 142 . In order to save the device space, the driving device 144 of the rotating disk 141 can be installed inside the main body of the connector 142 , and the top surface 1421 and the bottom surface 1422 can define the installation hole 206 for the driving device 144 . The driving device 144 is not limited, and may be a hydraulic motor or an electric motor.

The number of elastic pieces 143 can be the same as the number of brackets, and the two are arranged in one-to-one correspondence. The number of elastic pieces 143 can also be different from the number of brackets, and elastic pieces 143 are evenly spaced at the lower ends of a plurality of brackets. . Certainly, the elastic member 143 can also be one. In this case, the elastic member 143 is an integral structure, for example, a spring with a larger diameter.

The stage assembly 131 moves in the z direction (the third direction), thereby adjusting the height of the mounting holes 206 in the z direction, so that the axes of the corresponding mounting holes 206 between the generator rotor units coincide, and the adjustment accuracy is higher.

Further, the fixed platform assembly 131 is generally configured to be able to bear the weight of the rotor unit of the generator. At this time, in order to be able to apply the force of the lifting part 123 to the fixed table assembly 131, an adjustment substrate 132 can be fixedly arranged on the edge of the fixed table assembly 131 close to the lifting part 123, and the lifting part 123 drives the fixed table through the adjustment base plate 132. Assembly 131 is raised and lowered. By providing the adjusting base plate 132, it is possible to avoid making the fixing table assembly 131 too large, thereby increasing the weight and cost of the device.

Here, the lifting part 123 can be a hydraulic cylinder, and of course, it can also be of other structures, as long as the fixing table assembly 131 can be adjusted in the z direction (the third direction).
