The feed trolley is an indispensable equipment in the operation of the mill. When the mill is repaired, the mill liner is installed, and the mill liner is removed, the feed trolley needs to be moved. For smaller mills, the feed trolley is lighter and can be pushed by manpower. With the continuous development of science and technology, the cross-disciplinary and multi-field development continues to deepen, the level of digitalization and intelligence continues to improve, and mills are gradually developing in the direction of larger sizes. However, the feed trolleys of large mills are very heavy, and it is difficult to turn and move them by manpower. Other equipment, such as forklifts and cranes, are required. Not only are the projects complicated, costly, and labor-intensive, but there are also major safety hazards. Summary of the Invention

The motor is mounted on the motor base, the pinion is fixed to the output shaft of the motor and fixed by a shaft end baffle, the turntable is arranged on the outside of the pinion, and the large gear is fixed to the lower side of the turntable by a bolt assembly; the large gear is meshed with the pinion, and the rotation of the turntable is realized by the drive of the motor; the control system is arranged outside the device, and the rotation angle of the turntable is adjusted by controlling the drive of the main motor to realize the steering action of the feeding trolley.

[0005] A track is provided on the turntable for transporting the feeding trolley.

[0006] A rolling bearing is installed in the large gear through interference fit, and mainly bears the radial force from the turntable and the meshing force generated in the gear transmission.

[0007] The control system includes a remote control end, a main processor, a signal receiving and processing module, a motor controller, and a steering device. The remote control end sends a signal, the signal receiving module feeds back to the main processor, and the main processor sends instructions to the motor controller and the steering device. Then the motor drives the gear structure to rotate, driving the turntable to rotate, and the steering device controls the rotation position of the turntable.

[0008] The large gear is fixedly connected to the frame via a bolt assembly.

[0009] The frame is made of high-quality steel plates by welding.

[0010] The motor base is mounted on the base plate.

[0011] Beneficial effects: This design is an electric turntable device for steering the mill feeding trolley. The feeding trolley runs onto the electric turntable, and the motor drives the small gear to engage the large gear to rotate. The large gear drives the turntable to rotate. The feeding trolley is docked with the track and runs along the track. The control system controls the rotation position of the turntable, and it can rotate forward or reverse to achieve 0°~360° clockwise or counterclockwise rotation, so that the feeding trolley can be turned in and out conveniently and quickly when moving, avoiding the time-consuming and labor-intensive manual pushing of the traditional mill feeding trolley and the extremely high risk of hidden dangers, thereby enhancing the efficiency and safety of the operation.
