[0034] like Figure 1-11 As shown, a dual-mode anti-sway rigid hoisting system for the zero section and crystallizer of a wide plate casting machine includes a hoisting body 1. The hoisting body 1 is composed of a rigid frame 2 with a frame-to-mass ratio of ≥1:5 and a main crossbeam 3. A hook groove 4 is formed at the upper end of the rigid frame 2. The hook groove 4 and the main crossbeam 3 are integrally cut and formed.

[0035] The main crossbeam 3 has longitudinal beams 6 welded to both sides by submerged arc welding. The longitudinal beams 6 are detachably connected to the hoisting part 7, which is detachably connected to the hoisting hole of the plate casting machine and the crystallizer boss.

[0036] The welding bevel between the main crossbeam 3 and the longitudinal beam 6 is a K-type bevel with an angle of 35°.

[0037] To avoid stress concentration in the weld during use, the hook groove 4 formed at the upper end of the rigid frame 2 is formed by symmetrically arranged steel plates, and a connecting shaft 8 is fixedly installed between the hook grooves 4. The hook groove 4 is a space for inserting hooks.

[0038] The integral cutting and molding of the main crossbeam and hook groove can improve the overall stability and support strength.

[0039] To facilitate the fixing of the hoisting part 7 via the shaft hanging end 9 during use, shaft hanging ends 9 are provided at the four corners of the longitudinal beam 6 for hanging the hoisting part 7. The shaft hanging end 9 can rotate on the longitudinal beam 6. The shaft hanging end 9 includes a rod structure 10 that passes through the longitudinal beam 6 and a hook body 11 welded to the rod structure 10.

[0040] The aforementioned rod structure 10 and hook body 11 are integrated into one structure. The rod structure 10 passes through the longitudinal beam 6 and is fitted with a nut to the threaded section at the upper end of the rod structure 10.

[0041] In order to facilitate the elimination of lateral forces by hoisting through the hoisting part during use, the hoisting part 7 includes a double guide chain structure 12, the upper end of which is connected to a collar buckle 13, and the collar buckle 13 cooperates with the hook body 11.

[0042] The lower part of the double guide chain structure 12 is fixed at an angle to both sides of the shaft connecting end 14. The shaft connecting end 14 includes a fixing part 15 and a tightening part 16. The lower part of the double guide chain structure 12 passes into the shaft connecting end 14 and is tightened by the tightening part 16, which is a nut. Threaded sections are fixedly provided on both sides of the shaft connecting end 14 to cooperate with the tightening part 16. The lower end of the double guide chain structure 12 is a ring structure.

[0043] A wire rope sleeve 17 is fitted at the center of the shaft connecting end 14. The lower end of the wire rope sleeve 17 is an annular sleeve 18, the size of which is slightly larger than the size of the crystallizer boss hanger.

[0044] To facilitate the limiting of the wire rope sleeve 17 at the shaft connection end 14 during use, a concave groove is provided on the shaft connection end 14 at the contact position with the wire rope sleeve 17, wherein the shaft connection end 14 is a shaft structure.

[0045] The above structure allows for the hanging and hoisting of the crystallizer boss. The ring is inserted into the upper left corner boss of the crystallizer, and the other three points are connected in a clockwise direction to ensure that the ring is in contact with the boss.

[0046] To facilitate the hoisting of the plate casting machine section during use, the center of the shaft connecting end 14 is connected to the hook 19 via the connecting rod 20. The connecting rod 17 and the hook 19 are an integral structure. A threaded end is provided at the upper end of the connecting rod 20 and fixed with a nut. The hook 19 is engaged with the hoisting hole of the plate casting machine section.

[0047] The shaft connecting end 14 is connected to the connecting rod 20 in a square column structure. The lower part of the double guide chain structure 12 passes into the shaft connecting end 14 and is tightened by the tightening part 16, which is a nut. Threaded sections are fixedly provided on both sides of the shaft connecting end 14 to cooperate with the tightening part 16.

[0048] In order to facilitate the limiting of the connecting rod 20 in use, a through hole is provided at the center of the shaft connecting end 14. The connecting rod 20 is passed through the through hole and connected to the threaded section at the upper end of the connecting rod 20 by a nut.

[0049] The longitudinal beams adopt a box-type structure. When welding with the rigid frame, diagonal support steel plates are added. The crystallizer hoisting operation procedure is as follows: Preparation: Insert the crane hook into the hook slot, select a suitable double guide chain structure (1500mm), and hang it on the hook body of the longitudinal beam; Connect the equipment [operator position] --> [fit the ring sleeve onto the upper left corner boss of the crystallizer] --> [connect the remaining three points clockwise in sequence] --> [confirm that the ring sleeve is in contact with the boss], hoisting control, slowly lift at a speed of ≤0.5m / min, hover 100mm off the ground, and check the guide chain tension deviation <5%.

[0050] The zero-section hoisting operation procedure involves removing the double guide chain structure of the crystallizer and installing another set of double guide chain structures, which is a long guide chain group (2200mm). The center position of the shaft connection end is connected to the hook of the zero-section hoisting hole through the connecting rod.

[0051] Height compensation verification: after lifting, the height of the bottom surface of the zero section from the roller conveyor is: traditional method: 350mm, this utility model solution: 1050mm, completely avoiding scratching and collision with the conveyor roller conveyor.

[0052] An application of a dual-mode anti-sway rigid hoisting system for the zero section and crystallizer of a wide plate casting machine is presented, which is used to solve the problems of swing control and force optimization during the hoisting process of the zero section and crystallizer equipment.
