The rope connection sliding assembly comprises an upper connection rope (5), a lower connection rope (15), a first connection plate (13) and a sliding rod (14); the upper connection rope (5) is installed at one end of the first winding wheel (4) and the second winding wheel (18); one end of the lower connection rope (15) is wound around one end of the first winding wheel (4) and the second winding wheel (18); the other end of the upper connection rope (5) and the lower connection rope (15) is installed with the first connection plate (13); and the sliding rod (14) is installed at the top of the first connection plate (13); The cutting process of the heavy-duty suspended laser tube cutting device includes the following steps: Step 1: The staff starts the third driving motor (26) to drive the third rotating rod (27) to rotate, and the third winding wheel (28) and the fourth winding wheel (30) are driven to rotate by the rotation of the third rotating rod (27), and the first suspension steel rope (29), the second suspension steel rope (31) and the upper laser cutting member (33) are lowered and adjusted to the cutting position by the third winding wheel (28) and the fourth winding wheel (30); Step 2: After adjustment, the staff places the pipes at equal intervals on the top of the storage member (23), starts the second drive motor (16) to drive the second rotating rod (17) to rotate, and the rotation of the second rotating rod (17) drives the second winding wheel (18) to rotate, and the upper connecting rope (5) and the lower connecting rope (15) are wound up by the rotation of the second winding wheel (18); Step 3: The upper connecting rope (5) and the lower connecting rope (15) are rolled up by the second rolling wheel (18) to drive the first connecting plate (13), the sliding rod (14), the storage basket (35) and the storage basket (35) to move, and the upper laser cutting piece (33) and the lower laser cutting piece (20) are used for cutting during the movement; Step 4: After cutting, the first rotating rod (3) is started to drive the first rotating rod (3) to rotate, and the first winding wheel (4) is driven to rotate by the rotation of the first rotating rod (3), and the upper connecting rope (5) and the lower connecting rope (15) are wound by the rotation of the first winding wheel (4); Step 5: The upper connecting rope (5) and the lower connecting rope (15) are wound up by rotating the first winding wheel (4), and the first connecting plate (13), the sliding rod (14), the storage basket (35) and the sliding plate (36) are pulled to move in the opposite direction of the second driving motor (16); Step 6: When the storage basket (35) is moved to the top of the discharge chute (6), the electric telescopic rod (9) is activated to drive the piston rod (10), the second connecting plate (22) and the storage member (23) outward, and the cut pipes are discharged and fall through the discharge chute (6) into the collection box (12) for storage.
