The pedestal plate 202 is bolted to the top of one end of the clamping component 1 through the bolt base 201, a slot box 203 is arranged on the top side of the pedestal plate 202, and a gearbox 204 connected to the output end of the driving motor 205 is arranged at one end of the slot box 203, a sliding seat 207 is threadedly connected to the slot box 203 through the worm gear group 206, and a telescopic canvas cover 208 is arranged on the upper side of the sliding seat 207, and a fixed base 209 is arranged at one end of the telescopic canvas cover 208.

[0021] The telescopic canvas cover 208 is of a flexible telescopic structure, and the tank box 203 and the gearbox 204 are symmetrically distributed about the central axis of the base plate 202.

[0022] In the present embodiment, after the pipe is clamped, the driving motor 205 is started to output power to drive the output end of the driving motor 205 to operate, and the output end of the driving motor 205 drives the gearbox 204 to operate after the operation, so that the gearbox 204 can drive the worm group 206 inside the trough box 203 to rotate after the operation, and the worm group 206 can drive the sliding seat 207 to slide to a real-time position suitable for grinding after the rotation operation, because the telescopic canvas cover 208 is a flexible and telescopic structure, waste materials can be prevented from invading the trough box 203 during grinding.

[0023] The clamping component 1 includes a cushion block 101, a base plate 102, a horizontal platform 103, a lower clamp block 104, a pneumatic telescopic frame 105 and an upper clamp block 106. The base plate 102 is arranged on the top side of the cushion block 101, the horizontal platform 103 is arranged on the top side of the base plate 102, the lower clamp block 104 is arranged on the top side of the horizontal platform 103, and pneumatic telescopic frames 105 for installing the upper clamp block 106 are arranged above both ends of the horizontal platform 103.

[0024] In this embodiment, when in use, the pad 101 and the base plate 102 interact with each other to place the equipment at the processing site, and then the base plate 102 is used to install the equipment, and then the material to be polished is placed in the lower clamping block 104 on the top side of the horizontal table 103, and then the pneumatic telescopic frame 105 is started to output power to drive the output end to operate, so that after the output end of the pneumatic telescopic frame 105 is running, the upper clamping block 106 and the lower clamping block 104 interact with each other to effectively clamp the product.

[0025] The grinding mechanism 3 includes a cylinder lifting seat 301, a double fixed plate 302, a rotating motor 303, a double disk 304, an adjusting worm 305, an adjusting base 306, a connecting rod 307, an electric rotating seat 308 and a grinding wheel 309. The cylinder lifting seat 301 is arranged on the top side of the sliding seat 207, and the double fixed plate 302 is arranged on the top side of the cylinder lifting seat 301.

[0026] In this embodiment, when grinding is required, the cylinder lift seat 301 is started to output power to drive the output end of the cylinder lift seat 301 to extend and retract, so that the output end of the cylinder lift seat 301 drives the double fixed plates 302 to move to a suitable height.

[0027] The inner end of the double fixed plate 302 is provided with a double disk 304 connected to the output end of the rotating motor 303 , and the double disk 304 is threadedly connected with an adjusting base 306 via an adjusting worm 305 .

[0028] In this embodiment, the rotating motor 303 outputs power to drive the output end of the rotating motor 303 to rotate. Through the operation of the output end of the rotating motor 303, the double disk 304 at the inner end of the double fixed plate 302 rotates to a real-time angle suitable for grinding. Then the adjusting worm 305 is started to rotate so that the adjusting worm 305 drives the adjusting base 306 to slide to a suitable position.

[0029] A connecting rod 307 is disposed at the inner end of the adjusting base 306 , and an electric rotating seat 308 is disposed at the inner end of the connecting rod 307 . A grinding wheel 309 is connected to the output end of the electric rotating seat 308 .

[0030] In this embodiment, when the adjustment base 306 slides to a suitable position, the grinding wheel 309 is aligned with the real-time grinding position inside the pipe, and then the output end of the electric rotating seat 308 at the inner end of the connecting rod 307 is started to drive the grinding wheel 309 to rotate, so that the grinding wheel 309 effectively grinds the pipe clamped by the clamping component 1 to complete the processing.

[0031] The working principle of the ductile iron pipe cement lining grinder is as follows: when in use, the pad 101 is placed at the processing site under the interaction of the base plate 102, and then the base plate 102 is used to install the equipment, and the material to be polished is placed in the lower clamping block 104 on the top side of the horizontal table 103, and then the pneumatic telescopic frame 105 is started to output power to drive the output end to operate, so that after the output end of the pneumatic telescopic frame 105 is running, the upper clamping block 106 and the lower clamping block 104 interact with each other to effectively clamp the product, and when the pipeline is clamped, the drive motor 205 is started to output power to drive the output end of the drive motor 205 to operate, and after the output end of the drive motor 205 is running, the gearbox 204 is driven to operate, so that after the gearbox 204 is running, the worm group 206 inside the trough box 203 can be driven to rotate, and after the worm group 206 rotates, it can drive the sliding seat 207 to slide to a real-time position suitable for grinding, because the telescopic canvas cover 208 is a flexible and telescopic structure. The shape of the double plate 302 is formed, so that waste can be prevented from invading the trough box 203 during grinding. When grinding is required, the cylinder lifting seat 301 is started to output power to drive the output end of the cylinder lifting seat 301 to extend and retract, so that the output end of the cylinder lifting seat 301 drives the double fixed plate 302 to run to a suitable height, and then the rotating motor 303 outputs power to drive the output end of the rotating motor 303 to rotate. Through the operation of the output end of the rotating motor 303, the double disk 304 at the inner end of the double fixed plate 302 is rotated to a real-time angle suitable for grinding, and then the adjusting worm 305 is started to rotate so that the adjusting worm 305 drives the adjusting base 306 to slide to a suitable position. When the adjusting base 306 slides to a suitable position, the grinding wheel 309 is aligned with the real-time grinding position inside the pipe, and then the output end of the electric rotating seat 308 at the inner end of the connecting rod 307 is started to drive the grinding wheel 309 to rotate, so that the grinding wheel 309 effectively grinds the pipe clamped by the clamping component 1 to complete the processing.
