The entrance looper trolley 3 and the exit looper trolley 8 are horizontally arranged back to back and travel on the lower rail 4. A plurality of entrance looper trolleys 2 and a plurality of exit looper trolleys 9 travel between the upper rail 12 and the lower rail 4. The first steel wire rope 5 runs in the entrance looper trolley 3 and is supported by lower steel wire rope rollers 18 arranged below the front and rear sides of the exit looper trolley 8; the second steel wire rope 7 runs in the exit looper trolley 8 and is supported by upper steel wire rope rollers 17 arranged above the entrance looper trolley 3.

[0024] like Figure 4-5 As shown, the entrance trolley 3 includes a frame 31, a wheel 32 located below the frame 31, and a first steering roller 33, a second steering roller 34 and an entrance winch 15 arranged above the frame 31.

[0025] The entrance winch 15 includes a motor 153, a reducer 157, a winch drum 151 and a winch drum 2 152. The motor 153 and the reducer 157 are connected via a coupling 154. A brake 155 is provided at the end of the coupling 154. The winch drum 151 and the winch drum 2 152 are coaxial and are connected at both sides of the output shaft of the reducer 157 by a coupling 2 156.

[0026] like Figure 4-5As shown, the export trolley 8 includes a frame 81 , a wheel 82 located below the frame 81 , and a third steering roller 83 , a fourth steering roller 84 and an export winch 16 arranged above the frame 81 .

[0027] The export winch 16 includes a second motor 163, a second reducer 167, a third winch drum 161 and a fourth winch drum 162. The second motor 163 and the second reducer 167 are connected via a third coupling 164. A second brake 165 is provided at the end of the third coupling 164. The third winch drum 161 and the fourth winch drum 162 are coaxial and are connected on both sides of the output shaft of the second reducer 167 by a fourth coupling 166.

[0028] An inlet wire rope fixed pulley 1 and an outlet wire rope fixed pulley 10 are respectively installed at the inlet end and the outlet end of the loop.

[0029] The entrance wire rope fixed pulley 1 is a double wheel, and the two ends of the first wire rope 5 are turned to the hoisting drum 1 151 and the hoisting drum 2 152 connected to the entrance hoist 15.

[0030] The outlet wire rope fixed pulley 10 is a double wheel, and the two ends of the second wire rope 7 are turned to the hoisting drum three 161 and the hoisting drum four 162 connected to the outlet hoisting machine 16.

[0031] The inlet trolley 3 and the multiple inlet trolleys 2 are connected in sequence by chains 11. When filling, the multiple inlet trolleys 2 support the steel belt at equal intervals; the export trolley 8 and the multiple export trolleys 9 are connected in sequence by chains 11. When filling, the multiple export trolleys 9 support the steel belt at equal intervals.

[0032] The inlet looper trolley 3 can be moved to the right end of the looper when filling the loop, and the outlet looper trolley 8 can be moved to the left end of the looper when filling the loop.

[0033] Working principle and working process of the present invention:

[0034] The strip steel at the entrance end of the strip steel production line is uncoiled by the uncoiler 13 and enters the entrance loop through the front-end process equipment. The entrance loop is a four-layer loop. Then the entrance and exit loops enter the production line process section 6, then enter the exit loop, and finally exit the loop and enter the coiler 14.

[0035] Inlet loop filling: The inlet loop trolley 3 needs to run to the right to the outlet loop end. At this time, the system controls the winding machine 14 to accelerate the winding, the outlet loop is released, and the outlet loop trolley 8 releases the second steel wire rope 7 by the outlet loop winch 16 arranged thereon. The outlet loop trolley 8 pushes the outlet loop trolley 9 to run to the right in turn. At the same time, limit switches are set on the inlet loop trolley 3 and the outlet loop trolley 8 to prevent the inlet loop trolley 3 from colliding with the outlet loop trolley 8.

[0036] Entrance loop release: the entrance loop trolley 3 needs to move to the left. At this time, the entrance winch 15 on the entrance loop trolley 3 releases the first steel wire rope 5. The entrance loop trolley 3 pushes the entrance loop trolley 2 in turn and moves to the left to shorten the entrance loop release.

[0037] When the export loop is filled, the export loop trolley 8 needs to move left to the left end of the import loop. At this time, the system controls the uncoiler 13 to slow down and unwind, and the import loop is released. The limit switches on the import loop trolley 3 and the export loop trolley 8 prevent the export loop trolley 3 from colliding with the import loop trolley 8.

[0038] Export loop release: the export loop trolley 8 needs to move to the right. At this time, the export loop trolley 8 pushes the export loop carrier 9 to move to the right in turn to shorten the release of the export loop.

[0039] In summary, the present invention provides a common looper for the entrance and exit of a steel strip production line, which is easy to design, manufacture and construct, occupies a small space and allows simple winding of the steel wire rope.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
