Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical containers, in particular to a metallurgical container tilting mechanism. Background Art

[0002] Metallurgical containers generally refer to ladle, or giant goblet or ladle, commonly known as ladle or large can, which is a container used to transport and pour molten metal. In many non-ferrous metal foundries, ceramic crucibles used to transport and pour molten metal are also considered ladle. Ladle consists of a steel shell, a refractory lining and an opening and closing control system, and its cross-section is generally circular;

[0003] Steel ladle is sometimes used as secondary steelmaking ladle, which plays an important role in steelmaking system. The volume of steel ladle is generally determined by the capacity of steelmaking furnace, which should be enough to hold all molten steel in converter and a small amount of slag for heat preservation. In principle, one steel ladle is used for one furnace.

[0004] For example, the utility model with application number 202011310929.6 discloses a metallurgical container tilting mechanism, which is fixedly connected to a first motor and a second motor through the outer ends of a cover rope reel and a pull rope reel, respectively, and the surfaces of the cover rope reel and the pull rope reel are respectively wound with a cover rope and a pull rope. This metallurgical container tilting mechanism solves the problem that the existing metallurgical container tilting mechanism is mainly manually assisted and manually driven, the workers have a poor operating environment, and there are high safety hazards. At the same time, the mechanical structure is complex, which is not conducive to later repair and maintenance. However, similar to the metallurgical container tilting mechanism in the above-mentioned document, during use, once the pull rope breaks structurally, or the pull rope reel and the cover rope reel fail structurally, unnecessary safety accidents will occur in the metallurgical container during the tilting process, and there is a lack of effective structural connectivity and structural support. Summary of the invention

[0005] The purpose of the utility model is to provide a metallurgical container tipping mechanism to solve the problems raised in the above background technology. The servo motor drives the vertical axial rotation of the lead screw, so that the slider on the surface of the lead screw can be adjusted in the vertical direction, thereby driving the hydraulic rod connected to it to rise and fall synchronously, and cooperating with the structural extension of the hydraulic rod, the main body of the steel ladle can be flexibly tilted and adjusted, while ensuring the support and stability of the bag structure. In addition, in conjunction with the structure of the auxiliary frame, the use of the shock-absorbing frame and the buffer pile can minimize the structural impact of the steel ladle body when the structure swings, and provide it with a certain structural limit effect.

[0006] By adopting the above technical solution, effective structural support and buffering are provided for the tipping of the steel ladle body.

[0007] Compared with the prior art, the utility model has the following beneficial effects: the metallurgical container tipping mechanism,

[0008] The lower end of the hydraulic rod is connected to the lower end of one side of the steel ladle body through a connecting shaft structure. When the servo motor is started, it will drive the screws connected to each other at the lower power output end to rotate axially in the vertical direction, so that the slider threadedly connected to the surface of the screw can be vertically lifted and lowered in the vertical direction, thereby driving the hydraulic rod connected to the slider to rise and fall synchronously, and cooperating with the structural extension and contraction of the hydraulic rod, the lower end of the steel ladle body can be driven to tilt and adjust. Through the use of the above structure, on the one hand, sufficient structural support and stability can be guaranteed in the process of adjusting the inclination of the steel ladle body, and on the other hand, the flexibility of the adjustment angle is maximized, so as to flexibly adjust the tilting angle of the steel ladle body according to needs.

[0009] By using the auxiliary frame, on the one hand, the structure of the damping shaft is utilized so that the main body of the steel ladle can be swung and adjusted within a certain range at the upper end of the support frame, thereby cooperating with the operation of the tipping assembly, which can provide structural stability support for the main body of the steel ladle while having sufficient structural flexibility. In addition, a shock-absorbing frame is installed on one side of the support frame, and a buffer pile is installed horizontally in the middle of the shock-absorbing frame. When the structural failure of the tipping assembly causes the structural swing of the main body of the steel ladle, the structural impact force can be absorbed and alleviated. While reducing the impact on each structural member, it can also play a role of structural limitation, which plays a limiting role to a certain extent and reduces the occurrence of safety accidents.

[0016] like Figures 1 to 3As shown, the auxiliary frame 2 includes a support frame 201, a damping shaft 202 and a fixing seat 203.

[0018] See also Figure 1-3 The utility model provides a technical solution: a metallurgical container tilting mechanism.
