Description

Technical Field

[0043] The scheme has the following working process: when pouring the skylight, the whole device is moved to the corresponding position, and then the PLC controller 800 is operated, the PLC controller 800 controls the rotary drive hydraulic motor 103, the rotary drive hydraulic motor 103 rotates to drive the L-shaped tube 105 to rotate, so that the telescopic tube 106 corresponds to a docking tube 200, and then the PLC controller 800 controls the two cylinders 108 to start synchronously, the cylinder 108 pushes the telescopic tube 106 to move, so that the side ring 202 contacts the first sealing ring 201, and then the PLC controller 800 controls the servo motor 604 The servo motor 604 is started, and the sixth gear 605 is driven to rotate. The sixth gear 605 is driven to rotate the second gear ring 702. The second gear ring 702 is driven to rotate the first gear ring 701. The first gear ring 701 is driven to rotate the fifth gears 603. The fifth gears 603 are driven to move the U-shaped rod 600 downward. The U-shaped rod 600 is driven downward to move the limit rod 300. The limit rod 300 is driven downward to move the first arc plate 301 and the second arc plate 304 downward, so that the first arc plate 301 contacts one side of the butt tube 200, and the second arc plate 304 contacts the side ring 201. 2 one side contacts, and then the PLC controller 800 controls the electric push rod 501 to start, the electric push rod 501 drives the third L-shaped rod 409 to move, the movement of the third L-shaped rod 409 drives the second rack 408 to move, the movement of the second rack 408 drives the fourth gear 405 to rotate, the rotation of the fourth gear 405 drives the third rotating shaft 404 to rotate, the transmission of the first bevel gear 402 and the second bevel gear 403 drives the second rotating shaft 407 to rotate, the transmission of the third gear 401 and the second gear 309 drives the first rotating shaft 307 to rotate, and then drives the first gear 308 to rotate, the first gear 404 drives the second rotating shaft 407 to rotate, and the first gear 404 drives the second rotating shaft 407 to rotate. The rotation of the wheel 308 drives the first rack 305 to move, and the movement of the first rack 305 drives the moving rod 302 to move, and then drives the second curved plate 304 to move. The second curved plate 304 and the first curved plate 301 cooperate with each other, so that the docking tube 200 and the side ring 202 are tightly connected.
