[0036] The crane system 400 includes a slewing bearing 410 arranged on the supporting gantry 120, the inner ring of the slewing bearing 410 is fixedly arranged on the main crossbeam 121, the top tower section 420 is installed on the outer ring of the slewing bearing 410, the outer ring of the slewing bearing 410 is provided with gear teeth 411, the driving gear 430 is meshed with the gear teeth 411, the driving gear 430 is installed on the output shaft of the driving motor 440, and the upper end of the top tower section 420 is provided with a crane 450.

[0037] The motor 440 rotates the driving gear 430, driving the outer ring of the slewing bearing 410 to rotate, thereby causing the top tower section 420 to rotate synchronously. A crane 450 is provided at the upper end of the top tower section 420 to realize the slewing drive of the crane 450. The crane 450 includes structures such as an arm, an arm trolley, and a winch. The arm trolley moves along the arm, and a fixed pulley is provided on the arm trolley.

First, the track 110 should be laid and installed, and then the gantry system 100 should be installed in the order from bottom to top, first the main and then the secondary. The top tower section 420 should be installed on the main crossbeam 121, and then the auxiliary devices such as the boom, counterweight, trolley, hoisting winch, hoisting rope and hook of the crane 450 should be installed. After the electrical commissioning of the gantry system 100 and the crane system 400 is completed, the crane 450 can be used to install the lifting system 500 in sequence, and then the crane 450 can be used to install the casting system 200 in sequence. After the overall commissioning is completed, the installation is completed.

[0056] An operating method of a novel tower crane type continuous casting device comprises the following steps: Step 1: operate the gantry system 100 and drive along the track 110 to the area to be poured, and align the discharge chute 321 of the discharge trolley 320 with the feed hopper 211 of the first feeder 210 .

[0057] Step 2, start the crane system 400, drive the top tower section 420 to rotate through the driving motor 440, so as to realize the rotation of the crane 450, and the trolley of the crane 450 moves back and forth on the arm, adjust the position of the hook 451, make the hook 451 align with the ring 261 on the external fabric machine 260, connect the hook 451 with the ring 261 through the rope, and release the connection between the lock rope and the ring 261.

[0058] Step 3: The conveying system 300 is started to convey concrete, and the concrete is conveyed to the first feeder 210, the second feeder 220, the inner distributor 270 and the outer distributor 260 in sequence. The top tower section 420 is driven by the driving motor 440 to rotate, so that the outer distributor 260 rotates horizontally. The crane 450 is used to lift the concrete up and down, so that the outer distributor 260 can swing up and down. After the discharge end of the outer distributor 260 is aligned with the pouring position, pouring can begin. The conveying system 300 and the conveying system 200 are started in sequence in the manner of starting the far end first and then the near end. After the concrete is conveyed to the outer distributor 260, the warehouse is distributed and poured.

[0059] Step 4: When the pouring system 200 is not used for pouring, the lifting ring 261 is connected to the lifting point 541 by a locking rope, and then the connection between the hook 451 and the lifting ring 261 is released, and the crane system 400 can perform lifting operations. This is the lifting working condition.

[0060] Step 5. With the increase of the pouring height of the warehouse, when the number of originally installed tower sections 520 is too large, resulting in the pouring height of the external placing machine 260 being unable to match the pouring point elevation, some tower sections 520 are dismantled. The operation method is: extend the piston rod of the lifting cylinder 560 and connect it with the tailstock 521 on the second tower section 520, release the pin connection between the lower part of the first tower section 520 and the second tower section 520, continue to extend the piston rod of the lifting cylinder 560, so that there is enough dismantling space between the first tower section 520 and the second tower section 520, and then use the hinged plate 522 to connect the hook 512 on one side of the jacking section 510, and use the hook 451 of the crane 450 to connect with the first tower section 520. The rear suspension point 524 is connected, and then the pin connection between the jacking section 510 and the first tower section 520 is released. The crane 450 is lifted, and the first tower section 520 rotates around the hook 512 until the first tower section 520 rotates to a horizontal state. Then the hook 451 and the front suspension point 523 of the first tower section 520 are connected through the suspension rope, and the connection between the hinged plate 522 and the hook 512 is released to complete the removal of the first tower section 520. Then the piston rod of the lifting cylinder 560 is retracted, and the second tower section 520 is aligned with the jacking section 510 and then pinned. Repeat the above steps to remove the subsequent tower sections 520 until the height of the lifting system 500 meets the pouring height requirement of the external concrete placing machine 260.

[0061] After the pouring operation or lifting operation is completed, the gantry system 100 stops running, the lifting ring 261 is connected to the lifting point 541 by a locking rope, and then the connection between the hook 451 and the lifting ring 261 is released, and the hook 451 is lifted to near the highest limit position, and then the trolley 130 is parked in a safe position and the power is disconnected.

[0062] As an alternative embodiment, the feeder 1 can be mounted on the bottom longitudinal beam 123 in a fixed manner or in a hinged and rotatable manner.

[0063] As an alternative embodiment, the portal system 100 may be in the form of multiple main beams and vertical columns in addition to the single main beam 121 and the inclined column 122 .

The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims.
