However, when the device is lifted, one end of the device is supported by a universal wheel, and the other end needs to be supported by an electric push rod for the whole device. There are many parts in the device, and the required supporting force is relatively large, so the manufacturing cost of the device is greatly increased. Utility Model Content

A polishing machine speed control device is proposed to solve the shortcomings of the prior art that the device needs to be supported as a whole, the device has many parts, the supporting force required is large, the manufacturing cost of the device is high, and the overall height of the device is adjusted, and the flexibility is poor.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A polishing machine speed control device comprises an adjusting frame, one side of the adjusting frame is fixedly connected to a column, the bottom of the adjusting frame and the column are provided with a plurality of universal wheels, and the adjusting frame and the column are moved by the plurality of universal wheels; it also comprises a driving assembly, and the driving group is located in the adjusting frame, a polishing disk is provided below the adjusting frame, a cross column is provided in the driving assembly, the bottom of the cross column is fixedly connected to a connecting base, the bottom of the connecting base is fixedly connected to a first connecting plate, and the first connecting plate is fixedly connected to the polishing disk, and the connection area between the first connecting plate and the polishing disk can be expanded by the first connecting plate; it also comprises a lifting assembly, and an upgrading assembly is arranged in the adjusting frame, and the upgrading assembly can drive the cross column to be lifted and lowered.

[0009] In a possible design, the driving assembly includes a supporting shaft rotatably connected to the adjusting frame, the outer wall fixed sleeve of the supporting shaft is provided with a first gear, the adjusting frame is fixedly connected with a driving motor, the outer wall fixed sleeve of the output shaft of the driving motor is provided with a second gear, and the second gear is meshed with the driving motor, and the cross column slides through the supporting shaft, and when the first gear rotates, the cross column can be driven to rotate through the supporting shaft.

[0010] In a possible design, the lifting assembly includes an electric push rod fixedly connected to an adjusting frame, the bottom end of the output shaft of the electric push rod is fixedly connected to a second connecting plate, the bottom of the second connecting plate is fixedly connected to a rotating sleeve, and the rotating sleeve can be driven to move up and down by the extension and retraction of the output shaft of the electric push rod, the top of the cross column is fixedly connected to a rotating plate, and the rotating plate is rotatably connected to the rotating sleeve, when the cross column rotates, it can rotate in the rotating sleeve through the rotating plate, and at the same time, the height of the rotating sleeve in the adjusting frame can be adjusted to drive the polishing plate to move up and down.

[0011] In one possible design, a controller is fixedly connected to the top of the column, a frequency converter is fixedly connected to the top of the adjustment frame, and the output end of the controller is electrically connected to the input end of the frequency converter, and the output end of the frequency converter is electrically connected to the input end of the drive motor.

[0012] In a possible design, a pushing frame is fixedly connected to the top of the column, and the polishing machine can be pushed to move by the pushing frame.

[0013] In a possible design, a control switch is provided on the top of the column, and the control switch is used to turn the electric push rod on and off.

[0014] In the present application, the pushing frame fixedly connected to the top of the column can be used as an operating handle to push and adjust the moving direction of the polishing machine. The movement is achieved through multiple universal wheels at the bottom, so that the equipment can move freely in the working area. The AC power is transmitted to the controller through the power plug and the power cord. The controller is connected to the frequency converter to power on, and the frequency of the power supply is changed through the frequency converter.

At the same time, the support shaft is rotatably connected in the adjustment frame, and the first gear is fixedly sleeved on the outer wall of the support shaft. When the second gear rotates, it drives the first gear and the supporting shaft to rotate together. Because the cross column slides through the supporting shaft, when the supporting shaft rotates, the cross column will also rotate accordingly. The electric push rod is controlled to be on and off by the control switch. When the electric push rod is energized, its output shaft begins to extend and retract. Since the second connecting disk is fixedly connected to the bottom end of the output shaft of the electric push rod, and the rotating sleeve is connected to the bottom of the second connecting disk, the extension and retraction of the output shaft of the electric push rod will drive the rotating sleeve to move up and down. At the same time, the top of the cross column is fixedly connected to the rotating disk, and the rotating disk is rotatably connected to the rotating sleeve. Therefore, when the cross column rotates, it can also rotate in the rotating sleeve through the rotating disk. The up and down movement of the rotating sleeve will adjust the height of the polishing disk through the cross column, the connecting base and the first connecting plate.
