[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] Please refer to Figures 1 to 3 , the present utility model provides a cleaning device for a rotor hollow shaft. The cleaning device is mainly used for cleaning the rotor hollow shaft, reducing the working intensity of operators, and improving the cleaning efficiency of the rotor hollow shaft.

[0024] In this specific embodiment, a cleaning device for a rotor hollow shaft, the cleaning device is used for cleaning the rotor hollow shaft C of a generator, and includes a clamping mechanism 1 and a flushing mechanism 2. The clamping mechanism 1 is used for fixing the rotor hollow shaft; the flushing mechanism 2 includes a liquid supply member 21, a moving member 22 disposed on one side of the clamping mechanism 1, and a spray pipe 23 connected to the moving member 22, and the spray pipe 23 is communicated with the liquid supply member 21. The liquid supply member 21 is used for conveying cleaning liquid to the spray pipe 23. Through the relative movement of the moving member 22 and the clamping mechanism 1, the spray pipe 23 is inserted into the rotor hollow shaft, and the spray pipe 23 can spray the cleaning liquid to flush the inside of the rotor hollow shaft.

[0025] In the actual working process, first, the rotor hollow shaft C needs to be placed in the clamping mechanism 1, and the rotor hollow shaft C is fixed by the clamping mechanism 1. Then, through the relative movement of the moving member 22 and the clamping mechanism 1, the spray pipe 23 is inserted into the rotor hollow shaft; finally, the liquid supply member 21 conveys the cleaning liquid to the spray pipe 23, and the cleaning liquid ejected at high speed through the spray pipe 23 flushes the inside of the rotor hollow shaft.

[0026] In this specific embodiment, it further includes a workbench 3. The clamping mechanism 1 is disposed on one side of the top of the workbench 3, the moving member 22 is disposed on the other side of the top of the workbench 3, and the liquid supply member 21 is disposed in the workbench 3.

[0027] Specifically, the workbench 3 is composed of a frame and a panel through welding, with good strength. Four moving rollers are provided at the bottom of the workbench 3, and at least one of the moving rollers has a braking function.

[0028] It should be noted that the clamping mechanism 1 is not limited to a specific structure, as long as it can fix the rotor hollow shaft, and no other limitations are made here.

[0029] In this specific embodiment, the clamping mechanism 1 includes a support block 11 fixed on the workbench 3, a telescopic member 12, and a pressing block 13 connected to the movable end of the telescopic member 12. The pressing block 13 is located directly above the support block 11. The telescopic member 12 can drive the pressing block 13 to move relative to the support block 11, so that the rotor hollow shaft is pressed between the pressing block 13 and the support block 11.

[0030] It should be noted that the telescopic member 12 is a frame fixed on the workbench 3 and a cylinder fixed on the frame. The movable end of the cylinder is fixedly connected to the pressing block 13. In addition, arc-shaped grooves are provided on the side surfaces of the pressing block 13 and the support block 11 close to each other, and the rotor hollow shaft can be fixed inside the arc-shaped grooves.

[0031] In this specific embodiment, the liquid supply member 21 includes a liquid storage tank 211 provided in the workbench 3 and a first liquid pumping pump 212. The liquid storage tank 211 contains cleaning liquid, and the liquid storage tank 211 is communicated with the spray pipe 23 through the first liquid pumping pump 212. It should be noted that the flow rate of the cleaning liquid sprayed through the spray pipe 23 is relatively large, and it can well wash the inside of the rotor hollow shaft.

[0032] It should be noted that the moving member 22 is not limited to a specific structure. In this specific embodiment, the moving member 22 includes a mounting seat 221 movably connected to the top of the workbench 3 and a first driving member 222 for driving the mounting seat 221 to slide relative to the workbench 3. The spray pipe 23 is fixed on the mounting seat 221.

The driving member is used to drive the L-shaped plate 2212 to slide relative to the vertical plate 2211 to adjust the distance between the spray pipe 23 and the top of the workbench 3.

[0034] It should be noted that since the hollow shafts of rotors of different models need to be cleaned, in order to ensure that the nozzle 23 can be inserted into the hollow shaft of the rotor, the L-shaped plate 2212 can be driven by the second driving member 2213 to slide relative to the vertical plate 2211, so that the axis of the nozzle 23 coincides with the axis of the hollow shaft of the rotor. In this specific embodiment, both the first driving member 222 and the second driving member 2213 are commonly sold electric push rods on the market. Of course, the first driving member 222 and the second driving member 2213 can also be pneumatic cylinders or hydraulic cylinders.

[0035] On the basis of the above solution, in order to ensure that the inside of the hollow shaft of the rotor can be cleaned more thoroughly, specifically, a rotary nozzle is provided at the other end of the nozzle 23. Among them, the rotary nozzle can be a commonly sold rotary nozzle on the market, and no other details will be described here.

[0036] On the basis of the above solution, in order to ensure that the cleaning liquid can be recycled, specifically, a collection tank 4 is further included. The collection tank 4 is arranged on the top of the workbench 3. The collection tank 4 is used to collect the cleaning liquid after flushing the hollow shaft of the rotor. A second liquid pumping pump 41 and a filter 42 are provided on the pipeline connecting the collection tank 4 and the liquid storage tank 211.

A moving member is arranged on one side of the clamping mechanism. The nozzle is connected to the moving member and is communicated with a liquid supply member. The liquid supply member is used to convey cleaning liquid to the nozzle. Through the relative movement of the moving member and the clamping mechanism, one end of the nozzle for supply is inserted into the hollow shaft of the rotor, and the nozzle can spray cleaning liquid to wash the inside of the hollow shaft of the rotor; there is no need for an operator to use a brush to cooperate with the cleaning liquid to clean the hollow shaft of the rotor, which reduces the working intensity of the operator and improves the cleaning efficiency of the hollow shaft of the rotor.

[0039] The specific embodiments of the present utility model described above do not constitute a limitation to the protection scope of the present utility model.
