[0034] In use, firstly, the connecting frame 12 and the roller 111 are driven to move upward by the electric push rod 11, and the fixed belt 7 is driven to unroll by the winding assembly 6, when the roller 111 contacts with the fixed belt 7, the roller 111 will expand the fixed belt 7 (so that the cable reel can pass below the fixed belt 7 when it moves to the right subsequently), then the cable reel is sent into the connecting frame 14 from left to right by the forklift, so that the bottom of the cable reel contacts with the roller 115, then the sliding block 17 and the push block 18 are driven to move leftward by the servo motor 120 driving the screw 121, when the push block 18 contacts with the cable reel on the connecting frame 14, the connecting frame 14 will press the push block 18 to rotate, and the elastic sheet 19 is deformed, when the push block 18 is separated from the cable reel on the connecting frame 14, the elastic sheet 19 restores to the original state, and the push block 18 is reversed and reset, then the sliding block 17 and the push block 18 are driven to move rightward by the servo motor 120 driving the screw 121 in reverse, when the push block 18 contacts with the cable reel on the connecting frame 14 again, the inclined surface 1801 on the push block 18 will contact with the cable reel, and at this time, the connecting frame 14 cannot press the push block 18 to reverse because the bottom of the push block 18 contacts with the top of the sliding block 17, therefore, the push block 18 will press the cable reel rightward synchronously by the inclined surface 1801, and the roller 115 can reduce the resistance when the cable reel moves, thereby assisting the cable reel to move, and the push block 18 will push the cable reel to the central position by the inclined surface 1801, so that the cable reel can be clamped in the groove 201 after moving rightward to be limited, after the cable reel is limited in the groove 201 after moving rightward, the push block 18 will press the cable reel by the inclined surface 1801, thereby limiting the cable reel to prevent the cable reel from shaking, then the sliding frame 5, the winding assembly 6 and the fixed belt 7 are driven to move rightward by the servo motor 13 driving the screw 14, until the fixed belt 7 moves above the cable reel, then the connecting frame 12 and the roller 111 are driven to move downward by the electric push rod 11 to reset, so that the roller 111 releases the fixed belt 7, and the fixed belt 7 is wound by the winding assembly 6, so that the fixed belt 7 is pressed on the cable reel to fix the cable reel on the connecting frame 14; then the gear 9 is driven to rotate counterclockwise by ninety degrees by the reduction motor 8, so that the rack 10 is driven to rotate clockwise by ninety degrees by the gear 9, thereby driving the turnover table 2 and the cable reel to turn over by ninety degrees, during which the cable reel is fixed by the fixed belt 7, so that the cable reel cannot fall or roll when it is turned over.After the cable reel is completed, the connecting frame 12 and the roller 113 are driven to move right by the electric push rod 111, and the fixed belt 7 is unwound by the winding assembly 6. When the roller 113 contacts the fixed belt 7, the roller 113 will expand the fixed belt 7 to loosen the cable reel after turning. Then the sliding frame 5, the winding assembly 6 and the fixed belt 7 are moved upward by the servo motor 3 driving the screw 4 to reverse and reset, so that the fixed belt 7 moves upward from the right side of the cable reel after turning (originally, the fixed belt 7 is above the cable reel, and after turning, the fixed belt 7 is on the right side of the cable reel). Then the sliding block 17 and the push block 18 are moved upward by the servo motor 220 driving the screw 221 to rotate, so that the push block 18 is separated from the cable reel after turning, and then the push block 18 loosens the cable reel. After that, the fork truck is used to fork the cable reel after turning from the turning table 2 to the right. After the cable reel after turning is forked, the sliding block 17 and the push block 18 are moved downward by the servo motor 220 driving the screw 221 to reverse and reset. Then the connecting frame 12 and the roller 113 are moved left by the electric push rod 111 to reset, so that the roller 113 loosens the fixed belt 7, and the fixed belt 7 is wound by the winding assembly 6. Finally, the gear 9 is rotated clockwise by ninety degrees by the reduction motor 8 to reset, so that the rack 10 is counterclockwise rotated by ninety degrees by the gear 9 to reset, thereby driving the turning table 2 to reverse and reset by ninety degrees.

[0035] Referring to Figure 7 and Figure 8 As shown in the drawings, the turning table 2 further comprises a limiting mechanism, the limiting mechanism comprises two limiting plates 122, two limiting plates 123, two electric push rods 124, a connecting rod 125, two stabilizing blocks 126 and two stabilizing blocks 127. The two limiting plates 122 are symmetrically arranged on the left lower side of the turning table 2, and a strip-shaped hole 12201 is formed on the limiting plate 122. The two limiting plates 123 are symmetrically arranged on the right upper side of the turning table 2, and a strip-shaped hole 12301 is formed on the limiting plate 123. The two electric push rods 124 are symmetrically arranged on the right lower side of the turning table 2. The telescopic rod of the electric push rod 124 is connected with the connecting rod 125, and the connecting rod 125 is movable in the strip-shaped hole 12201 and the strip-shaped hole 12301.

The two stabilizing blocks 127 are symmetrically arranged on the right upper side of the turning table 2, and the stabilizing block 127 is in contact with the limiting plate 123. The stabilizing block 127 is used for stabilizing the limiting plate 123.

[0036] When in use, the electric push rod 24 can drive the connecting rod 25 to move to the left upper side, so that the connecting rod 25 extrudes the limiting plate 22 and the limiting plate 23 to rotate, until the limiting plate 22 is parallel to the limiting plate 23; then when the forklift is used to move the cable reel from the turnover table 2 to the right, the limiting plate 22 and the limiting plate 23 can block the cable reel on the turnover table 2, so as to prevent the cable reel from rolling out to the front or rear side of the turnover table 2, thereby avoiding the collision accident of the cable reel with other objects; and by arranging the stabilizing block 26 and the stabilizing block 27, the stabilizing block 26 and the stabilizing block 27 can be used to stabilize the limiting plate 22 and the limiting plate 23 respectively, so as to improve the stability of the limiting plate 22 and the limiting plate 23, so as to prevent the limiting plate 22 and the limiting plate 23 from being deformed after being impacted by the cable reel; after use, the electric push rod 24 is used to drive the connecting rod 25 to move to the right lower side to reset, so that the connecting rod 25 extrudes the limiting plate 22 and the limiting plate 23 to reverse rotation reset.
