AI Technical Summary
The coverage range of the existing ladle water port hanger device is circled, and the hydraulic cylinder cannot be accurately positioned, which is inconvenient to operate and poor flexibility, especially in limited spaces, which are difficult to operate.
A foldable structure consisting of an inner link and an outer link is adopted to add hinge points to form a cover area as a plane rather than a line, achieving accurate positioning and flexible movement of the hydraulic cylinder.
The precise positioning and labor-saving operation of the hydraulic cylinder are realized, the flexibility and space adaptability of the device are improved, and the operation process in a limited space is simplified.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of continuous casting in the metallurgical industry, in particular to a ladle nozzle hanging cylinder device. Background Art
[0002] During the continuous casting process, each time the ladle is replaced, the opening and closing of the ladle nozzle is controlled by a hydraulic cylinder on the sliding nozzle. This hydraulic cylinder is suspended from the L-arm of the ladle turret via a ladle nozzle hanging cylinder device. During operation, the ladle nozzle hanging cylinder device moves the hydraulic cylinder to the slot on the ladle nozzle, thereby securing it to the ladle. Currently, this ladle nozzle hanging cylinder device is a single-hinged swivel mechanism, including a connecting rod with its rear end hinged to the L-arm of the ladle turret. The swivel radius is the connecting rod length L0, and the coverage area is a circle. This inconvenience is due to two points. First, because the coverage area is a circle, not a plane, it is impossible to ensure that the hydraulic cylinder is precisely moved above the sliding nozzle each time the position of the sliding nozzle changes. The hydraulic cylinder often needs to be manually lifted to the bottom of the ladle nozzle and then installed in the slot, which is time-consuming and inconvenient. Second, the connecting rod has a fixed swivel radius, which makes it difficult for workers to load and unload the hydraulic cylinder on the operating platform due to the limited platform space. Summary of the Invention
[0003] The purpose of the utility model is to solve the above technical problems and provide a ladle nozzle hanging cylinder device which has a simple and compact structure, is easy to operate, saves time and effort, and has good flexibility and adaptability.
[0004] The technical solution includes an L-arm of a ladle turret, a connecting rod with one end hinged on the L-arm of the ladle turret, and the other end of the connecting rod is connected to a hydraulic cylinder. The connecting rod consists of an articulated inner connecting rod and an outer connecting rod.
[0005] The length of the outer connecting rod is greater than that of the inner connecting rod.
[0006] The other end of the connecting rod is connected to the hydraulic cylinder via a chain.
[0007] The chain is detachably connected to the hydraulic cylinder.
[0008] The hinge between the inner connecting rod and the outer connecting rod adopts clearance fit.
[0009] In response to the problems existing in the background technology, the inventors have improved the ladle nozzle hanging cylinder device according to the actual needs of continuous casting production, including: changing the original connecting rod to a hinged inner connecting rod and outer connecting rod, adding a hinge point, and changing the original connecting rod into two sections, so that the connecting rod forms a foldable structure, 1) using the hinge of the two connecting rods, the coverage area of the translation can be increased, and the coverage range is changed from the previous line to a surface, and the trajectory of the horizontal movement can be flexibly controlled; 2) the two hinge points cooperate with the two connecting rods to achieve different states of free extension or folding, and are flexibly applicable to ladle sliding nozzles in various positions, and can accurately transport the hydraulic cylinder to the bottom of the ladle sliding nozzle for precise positioning without manual lifting and alignment; 3) because the folded structure is more compact and can be deformed freely, it can be flexibly operated in a smaller space, and has better spatial adaptability.
[0010] The utility model has the advantages of simple and compact structure, easy operation, time-saving and labor-saving, and good flexibility and adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further explained below with reference to the accompanying drawings:
[0015] See also Figure 1 The ladle turret L-arm is provided with a base 1. The rear end of the inner link 3 is hinged to the base 1 via a bracket 2, and the front end is hinged to the rear end of the outer link 4. The front end of the outer link 4 is detachably connected to the hydraulic cylinder 6 via a chain 5. The detachable connection can be achieved by hooking, clamping, or other detachable connection methods, which are not strictly limited here. Preferably, the length L1 of the outer link 4 is greater than the length L2 of the inner link 3. The foldable two-section link rotation covers an area of Figure 1 The shaded area has a maximum coverage radius R MAX =L1+L2, minimum coverage radius R MIN =L1-L2, the radius of gyration R can be MAX With R MINThe hydraulic cylinder 6 can be directly moved parallel to the position directly below the ladle sliding nozzle 8 when the cylinder is hung, and then the hydraulic cylinder 6 can be manually installed into the slot at the ladle sliding nozzle, which is flexible, convenient and labor-saving. The foldable structure is more compact, and the moving trajectory does not need to follow an arc, which is convenient for operation in a smaller space.
