Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3, an embodiment of the present utility model provides a technical solution: a system test bench for a large-scale turning gear, including a device body 1, the device body 1 includes a maintenance cabinet 2, a workbench 3, a rotation adjustment device 4 and a turning gear device 5, the workbench 3 is installed on the top of the maintenance cabinet 2, the rotation adjustment device 4 is installed on the top of the workbench 3, and the turning gear device 5 is installed on the top of the rotation adjustment device 4;

[0020] The rotation adjustment device 4 includes an adjustment motor 6, a sliding rail 7 and an adjustment disk 8. The adjustment disk 8 is located directly above the adjustment motor 6. A sliding block 9 is provided at the bottom of the adjustment disk 8. The sliding block 9 has an annular structure. The adjustment disk 8 is installed on the top of the sliding rail 7 through the sliding block 9. The sliding rail 7 has an annular structure. The adjustment motor 6 is located inside the maintenance cabinet 2. The top driving end of the adjustment motor 6 is connected to the bottom of the adjustment disk 8. A side connection ring 10 is provided on the outer side of the bottom of the sliding rail 7. A number of fixing holes 11 are provided on the surface of the side connection ring 10 in an annular and equally spaced manner. When connecting generators at different positions, the staff can drive the adjustment motor 6 in the rotation adjustment device 4. The driving end of the adjustment motor 6 drives the adjustment disk 8 to rotate, so that the connection direction of the turning gear device 5 on the adjustment disk 8 can be changed. When the adjustment disk 8 rotates, the sliding block 9 at the bottom of the adjustment disk 8 can rotate in the sliding rail 7, thereby increasing the stability of the adjustment disk 8 during rotation and ensuring the bearing capacity of the adjustment disk 8.

[0021] Furthermore, the turning gear device 5 includes a test motor 12, a first stabilizer 13, a second stabilizer 14 and a driving disk 15. The first stabilizer 13 and the second stabilizer 14 are both sleeved on the driving end of the test motor 12. The driving disk 15 is installed at the end of the driving end of the test motor 12. The driving disk 15 has a circular structure and a number of locking bolts 16 are provided on its surface in an annular and equally spaced manner. During connection, the staff pushes the device body 1, and then the driving disk 15 can be fitted with the driving end of the generator. Then the staff uses the locking bolts 16 to fix the two. During testing, the driving end of the test motor 12 is driven, and then the generator is driven through the driving disk 15.

[0022] Differently, the inside of the maintenance cabinet 2 is a hollow structure. A set of directional wheels 17 and steering wheels 18 are respectively provided at the bottom of the maintenance cabinet 2. A maintenance opening 19 is provided at the front end of the maintenance cabinet 2. A set of symmetrically distributed maintenance doors 20 are installed in the maintenance opening 19 through hinges. A maintenance window 21 is installed on the surface of the maintenance doors 20. The staff can move the device body 1 through the directional wheels 17 and steering wheels 18 at the bottom of the maintenance cabinet 2, and the maintenance door 19 is for the convenience of the staff to open, so as to perform maintenance work on the components inside the maintenance cabinet 2.

[0023] Working principle: During operation, when connecting generators at different positions, the staff can drive the adjustment motor 6 in the rotation adjustment device 4. The driving end of the adjustment motor 6 drives the adjustment disk 8 to rotate. Thus, the connection direction of the turning device 5 on the adjustment disk 8 can be changed. When the adjustment disk 8 rotates, the sliding block 9 at the bottom of the adjustment disk 8 can rotate within the sliding rail 7, thereby increasing the stability of the adjustment disk 8 during rotation and ensuring the bearing capacity of the adjustment disk 8. During connection, the staff pushes the device body 1, and then the driving disk 15 can be fitted with the driving end of the generator. Then, the staff uses the locking bolt 16 to fix the two. During testing, the driving end of the testing motor 12 is driven, and then the generator is driven through the driving disk 15.
