[0027] The inner diameter support assembly comprises two symmetrically arranged inner diameter support assemblies, coaxially mounted with the protective cover 1. Each inner diameter support assembly includes a conical shell 4, the two conical shells 4 being frustoconical in shape with their upper bottom surfaces facing each other. The two inner diameter support assemblies respectively abut against the two ends of the gear's inner hole. The upper conical shell 4 is movably installed inside the protective cover 1, while the lower conical shell 4 is fixedly installed on the inner bottom surface of the protective cover 1. An electric push rod 2 is fixedly installed on one side of the inner bottom surface of the protective cover 1. A lifting seat 17 is fixedly connected to the telescopic end of the electric push rod 2. A spur gear 15 is rotatably connected to the side of the lifting seat 17 facing the conical shell 4. The tooth surface of the spur gear 15 is rigidly connected to the lower bottom surface of the upper conical shell 4. Arm 5 and lifting seat 17 are also fitted with a rack 16 that meshes with a spur gear 15. The rack 16 slides along the central axis of the protective cover 1 and is connected to the lifting seat 17 by an electric telescopic rod 10. When placing the gear, the electric telescopic rod 10 installed on the lifting seat 17 retracts, causing the rack 16 to descend. This causes the spur gear 15, which meshes with the rack 16, to rotate counterclockwise, causing the connecting arm 5 to swing the upper conical shell 4 upward. This allows personnel to place the gear on the surface of the lower conical shell 4 without interference. Then, the upper conical shell 4 returns to its original position and descends under the contraction of the electric push rod 2 installed inside the protective cover 1 until it reaches the upper position and touches the inner hole on the other side of the gear, thus clamping the gear's inner hole.

[0028] The outer diameter support assembly is arranged in the conical shell 4, and comprises a plurality of swing arms 14 arranged in an annular array around the center line of the conical shell 4, one end of the swing arm 14 is hinged to one side of the upper bottom surface of the conical shell 4, and the swing arm 14 is inlaid and connected to the inner wall of the conical shell 4. The outer diameter support assembly further comprises a lifting frame 11 inlaid in the conical shell 4 and arranged coaxially, and a connecting plate 13 is hinged between the lifting frame 11 and each swing arm 14 in the same conical shell 4. The outer diameter support assembly is used to abut the gear end face. The electric telescopic rod 10 is also fixedly installed on one side of the lower bottom surface inside the conical shell 4, and the telescopic end of the electric telescopic rod 10 in the same conical shell 4 is fixedly connected to the surface of the lifting frame 11. When the gear inner hole needs to be cleaned, the upper conical shell 4 is lifted by a distance, the electric telescopic rod 10 in the conical shell 4 is elongated to realize the movement of the lifting frame 11, and then the swing arm 14 originally inlaid in the side of the conical shell 4 is turned out under the pushing action of the connecting plate 13. The swing arms 14 are used to contact the gear end face, and then the upper bottom surface of the conical shell 4 is separated from the inner hole of the conical shell 4, that is, the quick switching of the support mode can be realized.

[0029] Further, the protective cover 1 is also provided with an outer side support assembly, the number of the outer side support assembly is at least three, the outer side support assembly is arranged on the inner bottom edge of the protective cover 1 and arranged in an annular array around the conical shell 4, the outer side support assembly comprises a sliding seat 8 sliding relative to the conical shell 4, the sliding seat 8 is inlaid and rotatably connected with a vertically arranged roller shaft 3 on the side, the sliding rail 6 is fixedly installed on the inner bottom surface of the protective cover 1 at the position of each sliding seat 8, the sliding rail 6 extends along the radius direction of the protective cover 1 and is in sliding connection with the surface of the sliding seat 8, the lead screw 7 is rotatably connected in the sliding rail 6 and is in threaded connection with the sliding seat 8, one end of the lead screw 7 towards the conical shell 4 penetrates through the sliding rail 6 and is fixedly installed with a bevel gear block 12, the bevel gear ring 9 is rotatably connected on the inner bottom surface of the protective cover 1 and is in meshing connection with the bevel gear blocks 12. In actual use, the lead screw 7 is driven to rotate by installing a motor on one of the sliding rails 6, the bevel gear block 12 at the end of the lead screw 7 is simultaneously driven to rotate, the meshing connection between the bevel gear block 12 and the bevel gear ring 9 and the meshing connection between the bevel gear ring 9 and the bevel gear blocks 12 at other positions can realize the simultaneous rotation of the bevel gear blocks 12 at other positions, and then the simultaneous rotation of the lead screws 7 can be realized, that is, the simultaneous movement of the sliding seats 8 arranged relative to the conical shell 4 can be realized, and the roller shaft 3 arranged on the sliding seat 8 can be used to abut the outer side edge of the gear, so that the position of the gear lifted by the outer diameter support assembly in the protective cover 1 is stable.

[0030] The working principle is that when the outer wall of the gear is cleaned, the upper conical shell 4 is controlled to swing upward, at this time, the swing arm 14 is embedded in the side of the conical shell 4, the gear is placed on the lower conical shell 4 in a horizontal manner, and the upper conical shell 4 is reset by swinging towards each other and then continuously descending vertically to contact the upper inner hole of the gear, so that the outer wall of the gear is cleaned, when the inner hole of the gear is cleaned, the upper conical shell 4 is lifted by a distance, then the electric telescopic rod 10 in the conical shell 4 is elongated to realize the movement of the lifting frame 11, and then the swing arm 14 originally embedded in the side of the conical shell 4 is turned out under the pushing action of the connecting plate 13, the turned-out swing arms 14 contact the end face of the gear and push the gear upward, and then the upper bottom surface part of the conical shell 4 is separated from the inner hole of the conical shell 4, so that the quick switching of the supporting mode is realized, finally, the sliding seat 8 is moved to the gear direction until the surface roller 3 is attached to the outer wall of the gear, so that the inner hole of the gear is completely exposed, and the personnel can clean the inner hole of the gear.

[0031] The wiring diagram of the electric push rod 2, the electric telescopic rod 10 and the motor in the utility model belongs to the common knowledge in the field, and the working principle is a known technology, and the type is selected according to actual use, so the control mode and wiring arrangement of the electric push rod 2, the electric telescopic rod 10 and the motor are not explained in detail.
