[0016] Combine the following Figure 1-3 Further explain the utility model;

[0017] It includes a base plate 1, with walking wheels 2 installed at both ends of the base plate, and a release agent box 3 installed on the base plate; it also includes an arc-shaped outer frame 4, the lower end of the outer frame is fixed to the left and right sides of the base plate, and an arc-shaped limit frame 5 is arranged on the outer side of the outer frame. The radius of the limit frame is greater than the radius of the outer frame, and the left and right ends of the bottom of the limit frame are respectively fixed to the left and right ends of the bottom of the outer frame by pull rods 6, and a plurality of adjustment spraying mechanisms are arranged on the outer frame and the limit frame; the walking wheels on the base plate are placed on tracks 7.

[0018] A grinding mechanism is provided in the middle of the bottom plate, and the grinding mechanism includes a base 8, which is fixed on the bottom plate, the lower end of the telescopic rod 9 is hinged on the base through a hinge shaft, the worm wheel 10 is installed on the hinge shaft, the worm 11 is installed in the base, the worm wheel and the worm are meshed, one end of the worm is connected to the output shaft of the first motor 12, the first motor is installed on the base, and the first motor drives the worm to mesh with the worm wheel to rotate, so that the telescopic rod swings left and right with the hinge shaft; the upper end of the telescopic rod is installed with a second motor 13, and the grinding wheel 14 is installed on the output shaft of the second motor. The grinding depth or height of the tunnel wall can be adjusted by the extension and retraction of the telescopic rod, and the grinding direction can be adjusted by the worm meshing with the worm wheel.

[0019] The telescopic rod is an electric telescopic rod.

[0020] The regulating spraying mechanism includes a wire drum 15, which is rotatably connected to the outer frame 4, and the two ends of the wire drum extend from both sides of the outer frame respectively. The end of the wire drum facing the bottom plate is fixed with a first gear 16, and also includes a second gear 17 meshing with the first gear. The second gear is installed on the output shaft of the third motor 18, and the third motor is fixed on the outer frame. The wire tube 19 is threadedly connected in the wire drum, and the length of the wire tube is greater than the length of the wire drum. The end of the wire tube facing the bottom plate is connected to the demoulding agent box through a hose 20, and the other end of the wire tube extends from the limit frame. The nozzle 21 is installed at the end of the wire tube extending from the limit frame. The guide cylinder 22 is fixed on the outward surface of the limit frame, and the guide rod 23 is slidably arranged in the guide cylinder, and the other end of the guide rod is fixed on the nozzle.

[0024] When it is necessary to spray the release agent on the tunnel wall, first start the third motor to drive the gear to rotate, and then drive the wire tube to rotate. Since the wire tube is threadedly connected to the wire tube, and the nozzle at the end of the wire tube is restricted by the guide rod and the guide cylinder, the wire tube will adjust the position of the nozzle, and the guide rod will slide in the guide cylinder until the nozzle is at a suitable distance from the tunnel wall. Then the release agent in the release agent box is transported to the wire tube by a hose, and finally sprayed on the tunnel wall. When it is necessary to grind the demolded tunnel wall, start the telescopic rod so that the grinding wheel is located on the tunnel wall, start the second motor, and the grinding wheel can be rotated for grinding. When it is necessary to adjust the grinding direction of the grinding wheel, start the first motor, the worm meshes with the worm wheel to rotate, and the worm wheel drives the telescopic rod to rotate, so that the grinding direction of the grinding wheel changes, and the tunnel wall can be flexibly polished.
