The wireless signal receiver 58 and the first wireless signal receiver 59 are both KR1204-4 model wireless receivers.

The working principle is as follows: when the device is used, as shown in fig. 3, the device is put into a pipeline from a pipeline port, then a worker gives an instruction of starting two second motors 46 to two first wireless signal receivers 59 through a remote controller, so that the two second motors 46 are started to operate, the second motors 46 drive the lead screws 53 to rotate when operating, the lead screws 53 can drive the lead screw nuts 54 to move on the lead screws 53 when rotating, the lead screw nuts 54 are driven to move towards the mounting blocks 49 through the second motors 46, the lead screw nuts 54 synchronously drive the first sleeves 57 to move towards the mounting blocks 49 through the first sliding rods 56 when moving, in the process, the tapered surfaces on the side walls of the first sleeves 57 simultaneously push the four L-shaped rods 51, and further the four first rollers 52 cling to the inner wall of the pipeline, so that after two groups of first rollers 52 at two ends of the device are tightly adhered to the inner wall of the pipeline, the instruction of the remote controller gives the first wireless signal receivers 59 to stop the second motors 46, the device can be positioned in the pipeline stably by two groups of first rollers 52, then two first electric telescopic rods 35 are started by a remote controller for a wireless signal receiver 58 (as shown in fig. 4), when the two first electric telescopic rods 35 receive a starting command, synchronous stretching is realized under the action of the PLC controller 34, so that the stretching ends of the two first electric telescopic rods 35 retract, two connecting rods 36 are pulled synchronously when the stretching ends of the two first electric telescopic rods 35 retract, the connecting rod 36 pushes the mounting plate 10 through the connecting plate 37 when being pulled, so that the n-shaped plate 9 moves towards the inner wall direction of the steel pipe, when the n-shaped plate 9 moves under the pushing of the connecting plate 37, the n-shaped plate 9 can pull the sleeve 6 to slide on the cross rod 4 for a certain distance through the pull rod 7, because enough sliding space is reserved between two limiting rings 5 on the cross rod 4 for the sleeve 6, therefore, the movement of the n-shaped plate 9 cannot be influenced, along with the movement of the n-shaped plate 9, the grinding block 29 is firstly contacted with the inner wall of the steel pipe, then the rolling balls 18 and the rolling wheels 23 on the ejector rod 17 are contacted with the inner wall of the steel pipe, after the rolling wheels 23 are tightly attached to the inner wall of the steel pipe, an instruction of stopping the first electric telescopic rod 35 is given to the wireless signal receiver 58 through a remote controller, and the device is well fixed and placed in the steel pipe. At this time, when the remote controller gives an instruction to start the electric telescopic rod 2 to the wireless signal receiver 58, the electric telescopic rod 2 performs reciprocating telescopic motion under the action of the PLC controller 34, the telescopic end of the electric telescopic rod 2 can synchronously drive the cross rod 4 to move in the telescopic process, when the cross rod 4 moves back and forth along with the telescopic end of the electric telescopic rod 2, the sleeve 6 can also move back and forth along with the cross rod 4 under the blocking of the two spacing rings 5, when the sleeve 6 moves, the slide rod 31 can be synchronously driven to move back and forth by the pull rod 7, when the slide rod 31 moves back and forth, the belt 28 can be driven to move back and forth, when the belt 28 drives the polishing block 29 to move back and forth, dirt on the inner wall of the pipeline can be effectively polished away when the polishing block 29 moves back and forth, at this time, the remote controller gives an instruction to start the two first motors 47 to the two first wireless signal receivers 59 simultaneously, when the two first motors 47 are operated, the output ends of the two first motors 47 can rotate relatively in the same direction, drive two connecting rods 36 and rotate in the same direction in step, along with the rotation of connecting rod 36, a plurality of n shaped plate 9 rotates thereupon in step, and a plurality of sanding block 29 can rotate the pipeline inner wall of polishing this moment, and then reaches the purpose of polishing the dirt of steel pipe inner wall. Since the grinding block 29 is firstly contacted with the inner wall of the steel pipe, and then the roller 23 is contacted with the inner wall of the steel pipe, when the roller 23 is contacted with the inner wall of the steel pipe, the grinding block 29 can press and pull the belt 28, the first guide wheel 19-1 can move for a certain distance towards the direction of the guide wheel 19 along with the pulling of the belt 28, the first guide wheel 19-1 synchronously drives the square rod 24 to move when moving, at the moment, the spring 27 is extruded, and the spring 27 always gives reverse acting force to the first guide wheel 19-1. So that the belt 28 between the first guide wheel 19-1 and the guide wheel 19 is always in a tightened state, and it is ensured that the polishing block 29 is always tightly attached to the inner wall of the steel pipe, when the square rod 24 is pulled, the stopper 25 at the side end thereof drives the tapered rod 26 to synchronously move, when the tapered rod 26 moves along with the square rod 24 toward the guide wheel 19, the tip of the tapered rod 26 presses the first control switch 12 of the plurality of control switches 12 installed side by side, when the first control switch 12 is pressed, the motor 22 drives the roller 23 to rotate clockwise by a certain angle (the rotation angle can be freely set by the PLC controller 34) under the action of the PLC controller 34, when the roller 23 rotates by a certain angle, because the roller 23 rotates synchronously with the n-shaped plate 9, at this time, the roller 23 gives forward advancing force to the device, so that the device can realize a working process of slowly advancing while polishing, the device effectively achieves the purpose of automatic advancing, as the device advances in the pipeline, when encountering a thick dirt part on the inner wall of the pipeline, the grinding block 29 can continuously press the belt 28, at the moment, the belt 28 is pulled again, the conical rod 26 continuously moves towards the guide wheel 19 to press a second control switch 12 (or a third control switch 12, or a fourth control switch 12, or a fifth control switch 12 …) in the plurality of control switches 12 arranged side by side, the thickness of the dirt on the inner wall of the pipeline determines the position of the pressed control switch 12, the thicker the dirt is, the later the position of the pressed control switch 12 in the plurality of control switches 12 is, when the second control switch 12 is pressed, the roller 23 returns to a certain angle under the drive of the motor 22, when the third control switch 12 is pressed, the roller 23 returns to a certain angle under the drive of the motor 22, analogize with this, along with being pressed control switch 12 the position leans on the angle of returning of back gyro wheel 23 and increases progressively, along with the returning of gyro wheel 23 just, gyro wheel 23 drives the speed that this device spiral gos forward and slows down, because the speed that this device gos forward becomes slow, the time that the piece 29 of polishing was polished in the dirt is thick place can become the length, thereby the effectual thick place of assurance dirt also can be abundant ground, and ingenious setting between through a plurality of control switch 12 and motor 22, can effectual automatic control this device speed of marcing according to the thickness of dirt, thereby realize the long function of automatic control polishing time through automatic control forward speed.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
