Description

Technical Field

[0001] The utility model relates to the field of iron and steel metallurgy, and more specifically, to a ladle tilting device. Background Art

[0002] At present, in the continuous casting and steelmaking workshops of most steel mills in the metallurgical industry at home and abroad, it is necessary to equip the ladle with hot repair equipment, that is, the ladle tilting device. The ladle can be tilted to a certain angle through the ladle tilting device, so as to facilitate the slag cleaning and maintenance of the ladle. When the existing ladle tilting device is working, the hook on the ladle is generally lifted to drive the ladle to flip. The tilting torque required for the ladle to tilt is relatively large. After long-term use, the tilting support is very easy to deform and the side wall is easy to break, posing a great safety hazard. When a small number of ladle tilting devices tilt the ladle, the hydraulic cylinder is used as the power source to drive the ladle to flip. When the hydraulic cylinder is working, it needs to be equipped with a hydraulic station, which has a complex structure and requires additional space. Utility Model Content

[0003] The purpose of the utility model is to provide a ladle tilting device to solve the above problems.

[0004] The utility model solves the above technical problems with the following technical solutions: a ladle tilting device, comprising:

[0005] A tilting seat, on which two sets of fixing mechanisms are arranged at intervals, the fixing mechanisms include fixing frames and positioning hooks arranged opposite to each other, the positioning hooks are rotationally connected to the tilting seat, and are transmission-connected to a driving assembly arranged on the tilting seat, when the ladle is placed on the tilting seat, its two trunnion seats are respectively placed on the two fixing frames, and the driving assembly drives the corresponding positioning hooks to rotate so that the positioning hooks hook or release the trunnions of the ladle;

[0006] The tilting mechanism is connected with the tilting seat in driving connection to drive the tilting seat to rotate.

[0007] Furthermore, in the ladle tilting device, the tilting seat comprises:

[0008] Two tilting frames arranged opposite to each other, each of which is provided with the fixing frame;

[0009] Two ends of a plurality of connecting beams are respectively connected to the two tilting frames.

[0025] The following further describes the present utility model in detail with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.

[0026] It should be noted that in the description of the present utility model, the orientation or positional relationship indicated by the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0027] Figure 1 - Figure 2 A ladle tilting device provided by an embodiment of the present utility model includes:

[0028] A tilting base, on which two groups of fixing mechanisms are provided at intervals. The fixing mechanism includes a fixing frame (12) and a positioning hook 2 arranged oppositely. The positioning hook 2 is rotatably connected to the tilting base and is in transmission connection with a driving component arranged on the tilting base. When the ladle 11 is placed on the tilting base, its two trunnion seats are respectively placed on the two fixing frames 12. The driving component drives the corresponding positioning hook 2 to rotate, so that the positioning hook 2 hooks or releases the trunnion of the ladle 11.

[0029] A tilting mechanism, which is in transmission connection with the tilting base to drive the tilting base to rotate.

[0030] In this embodiment, in the initial state, the tilting base is in a horizontal state, and the position of the tilting base is locked by the tilting mechanism. Then the ladle 11 is hoisted above the tilting base, and then the ladle 11 is slowly lowered so that the two trunnion seats of the ladle 11 are respectively placed on the two fixing frames 12. As Figure 2 shown, the end of the trunnion seat of the ladle 11 away from the positioning hook 2 abuts against the fixing frame 12. Then the driving component drives the positioning hook 2 to rotate towards the trunnion, so that the positioning hook 2 hooks the trunnion of the ladle 11. At this time, the tilting base rotates towards the fixed seat direction, the fixing frame 12 blocks the trunnion seat, and the positioning hook 2 hooks the trunnion backward, so that a stable connection can be maintained between the ladle 11 and the tilting base. Then the tilting mechanism starts to work, drives the tilting base to rotate, and thus drives the ladle 11 to rotate for tilting. When the tilting of the ladle 11 is completed, the tilting mechanism drives the tilting base to rotate to the horizontal state and locks the tilting base. The driving component drives the positioning hook 2 to rotate away from the trunnion, so that the positioning hook 2 is moved away from the trunnion of the ladle 11, disconnecting the fixation between the ladle 11 and the tilting base, and then the ladle 11 can be hoisted away.

[0031] Preferably, as another embodiment of the present utility model, the tilting base includes:

[0032] Two oppositely arranged tilting frames 1, on which the fixing frames 12 are provided;

[0033] A plurality of connecting beams 5, with both ends respectively connected to the two tipping frames 1.

[0034] Preferably, as another embodiment of the present utility model, the driving assembly includes:

[0035] A driving motor 4, which is arranged on the tipping frame 1;

[0036] A lead screw slide 3, which is arranged on the tipping frame 1 and is in transmission connection with the driving motor 4. The middle part of the positioning hook 2 is rotatably connected to the tipping frame 1, and its end is rotatably connected to the slider of the lead screw slide 3.

[0037] In this embodiment, the driving motor 4 drives the ball screw of the lead screw slide 3 to rotate, so that the slider of the lead screw slide 3 makes a linear motion, driving the end of the positioning hook 2 to move. Since the slider can only drive the end of the positioning hook 2 to make a linear movement, a sliding groove needs to be provided in the middle part of the positioning hook 2, and a fixed shaft is provided on the tipping frame 1. The fixed shaft passes through the sliding groove. When driving the end of the positioning hook 2 to make a linear movement, the fixed shaft slides in the sliding groove, which can ensure the rotational connection between the middle part of the positioning hook 2 and the tipping frame 1.

[0038] Preferably, as another embodiment of the present utility model, the tipping mechanism includes:

[0039] Two bearing seats 6. Connecting shafts are provided on both of the two tipping frames 1, and the connecting shafts are respectively rotatably connected to the two bearing seats 6;

[0040] A tipping assembly, which is in transmission connection with one of the connecting shafts. The tipping assembly includes:

[0041] A turning motor 10;

[0042] A speed reducer 8, whose input end is in transmission connection with the turning motor 10 through a brake 9, and whose output end is connected to the connecting shaft through a coupling 7.

[0043] In this embodiment, when the turning motor 10 works, the brake 9 is released, and the turning motor 10 drives the two connecting shafts on the tipping frame 1 to rotate, thereby driving the tipping frame 1 to rotate. When the turning motor 10 does not work, the brake 9 is locked, thereby locking the input shaft of the speed reducer 8, and further locking the rotating shaft.

[0044] Although the embodiments of the present utility model have been disclosed as above, it is not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present utility model. For those skilled in the art, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present utility model is not limited to the specific details and the embodiments shown and described herein.
