[0037] Please refer to Figures 7-8 , the bottom end of the fixed shaft rod 83 is fixedly connected with a tension spring 85, the bottom end of the tension spring 85 is rotatably connected to the inner wall of the bottom end of the movable chamber 82, when the side roller 81 moves downward, the tension spring 85 will be stretched, and then the side roller 81 can be assisted to reset upward through the tension spring 85, the top end inner wall of the lower movable chamber 82 is provided with a pressure sensor 86 at a position corresponding to the threaded shaft rod 84, and the output end signal of the pressure sensor 86 is connected with a PLC controller.

[0038] Please refer to Figures 9-10 , the inside of the two sides of the side roller 81 close to the lower movable chamber 82 is internally provided with a sliding groove 811, and the sliding groove 811 penetrates into the inside of the movable chamber 82, the inside of the sliding groove 811 is fixedly connected with an electric telescopic rod 812, the output end of the PLC controller is signal connected with the electric telescopic rod 812, and the side of the electric telescopic rod 812 close to the movable chamber 82 is fixedly connected with a semicircular threaded sleeve ring 813, the semicircular threaded sleeve ring 813 is a semicircular arc ring, and the threaded shaft rod 84 is threadedly connected inside the two groups of closed semicircular threaded sleeve rings 813, when the side roller 81 rotates, the semicircular threaded sleeve ring 813 rotates around the threaded shaft rod 84, and then the side roller 81 moves downward when rotating, until the threaded shaft rod 84 extrudes and contacts the pressure sensor 86, at this time, the pressure sensor 86 transmits a signal to the PLC controller.

[0039] Working principle: please refer to Figures 1-10 , first put the track bracket 1 on both sides of the foundation pit, at this time the rack body 2 is located inside the foundation pit, then fill the concrete into the inside of the feeding groove 4, then start the lining machine, the rack body 2 moves horizontally along the guide rail 3 through the connecting frame 5, and the concrete is extruded and laid on the bottom side of the channel through the bottom roller 6, and the concrete is extruded and laid on both sides of the channel through the two sides of the trimming part 8;

[0040] At the same time, the servo motor 72 is started to drive the rotating column 73 to rotate counterclockwise, and the rotation of the rotating column 73 extrudes the guide rod 732 through the curved sliding groove 731, drives the guide rod 732 to move back and forth along the track of the curved sliding groove 731, so as to drive the movable block 733 to move back and forth synchronously, and the movement path of the movable block 733 is limited by the limiting rod 734 rolling in the limiting sliding groove 77, so as to ensure the horizontal movement of the movable block 733;

[0041] The back and forth reciprocating movement of the movable block 733 drives the limiting sliding block 75 to move synchronously in the limiting hollow plate 74 through the connecting block 735, thereby driving the scraper 76 to move back and forth reciprocatingly, and the other movable block 733 also moves back and forth, so as to drive the other group of staggered scrapers 76 to move back and forth reciprocatingly, thereby trimming the concrete on the bottom side of the channel, which can reduce the labor intensity of workers by replacing manual operation;

[0042] Secondly, when the two side rollers 81 roll along the channel to lay the concrete, since the movable chamber 82 rotates to drive the closed half circular threaded sleeve ring 813 to rotate around the outside of the threaded shaft 84, the side roller 81 as a whole moves downward, and at the same time stretches the tension spring 85, and when the side roller 81 moves downward to drive the pressure sensor 86 and the threaded shaft 84 to extrude and contact, the pressure sensor 86 transmits a signal to the PLC controller, thereby controlling the electric telescopic rod 812 to retract to drive the half circular threaded sleeve ring 813 away from the threaded shaft 84, so that the side roller 81 is no longer limited, and the side roller 81 is reset upward by the tension spring 85;

[0043] At this time, since the pressure sensor 86 is no longer pressed, the PLC controller controls the electric telescopic rod 812 to drive the half circular threaded sleeve ring 813 to close again, and the threaded shaft 84 is threadedly connected in the closed two half circular threaded sleeve rings 813, so that the side roller 81 can move up and down back and forth while rolling along the channel, which plays a role in trimming the uneven sides of the channel.

[0044] In summary, the channel concrete lining one-time forming machine drives the rotating column 73 to rotate through starting the servo motor 72, simultaneously drives the guide rod 732 to move back and forth along the track of the curved chute 731, drives the movable block 733 to reciprocate, and further drives the limiting sliding block 75 to reciprocate in the inside of the limiting hollow plate 74, so that the scraper 76 moves back and forth on the channel bottom side concrete surface, and the other group of staggered scrapers 76 can trim the channel bottom side concrete surface, so that the channel bottom side surface can be trimmed by replacing manual trimming, and the construction efficiency is improved.
