Description

Technical Field

[0001] The utility model relates to the technical field of converter steelmaking, in particular to a converter inclination angle data acquisition device. Background Art

[0002] Converter steelmaking uses molten iron, scrap steel, and ferroalloys as the main raw materials. The steelmaking process is completed in the converter without the help of external energy. The heat is generated by the physical heat of the molten iron itself and the chemical reactions between the components of the molten iron.

[0003] During the converter steelmaking process, it is necessary to control the converter body to tilt to different angles according to process requirements to perform operations such as adding scrap steel, sampling, adding molten iron, tapping steel, and tapping slag. Therefore, the control of the converter tilting angle is particularly critical.

[0004] Traditionally, the converter tilt angle is controlled by manual experience. One person visually observes the converter tilt angle and directs another person to manually operate the converter based on the actual angle observed. This method, which relies on manual experience and visual observation, has large errors and a low degree of automation.

[0005] To improve the automation level of converter inclination control, existing technology uses an encoder installed on the side of the converter reducer to collect data. This method primarily uses the encoder to collect data on the rotation of the reducer's final gear stage, which in turn determines the converter's trunnion rotation and the converter's inclination. However, because the reducer's gears consist of multiple stages, data loss occurs at each stage, resulting in significant errors in the final converter inclination data. Utility Model Content

[0006] Based on this, it is necessary to provide a converter inclination angle data acquisition device with high measurement accuracy to address the above technical problems.

[0007] The utility model provides a converter inclination angle data acquisition device, which is arranged on one side of the trunnion of the converter and includes a large gear, a small gear assembly, a coupling and an encoder for collecting coupling rotation data;

[0008] The large gear is fixedly sleeved on the trunnion of the converter;

[0009] The pinion assembly is provided with a pinion, a first bearing seat, a second bearing seat, and a rotating shaft;

[0010] The first bearing seat and the second bearing seat are both fixed to the ground, and the second bearing seat is located on a side of the first bearing seat away from the trunnion bearing seat;

[0011] One end of the rotating shaft can be rotatably assembled on the first bearing seat, and the other end of the rotating shaft can be rotatably assembled on the second bearing seat;

[0012] The pinion is fixedly sleeved on the rotating shaft, the axis of the rotating shaft is parallel to the axis of the trunnion, and the pinion is meshed with the large gear;

[0013] The coupling is arranged on a side of the second bearing seat away from the first bearing seat, and the coupling is fixedly connected to the transmission shaft;

[0014] The encoder is arranged at one end of the coupling away from the first bearing seat, and the encoder is fixedly connected to the coupling.

[0015] In one embodiment, the large gear is disposed between the trunnion bearing seat and the converter rotary joint.

[0016] In one embodiment, a display is further provided, and the encoder is connected to the display signal.

[0017] In one embodiment, the inner diameter of the large gear is equal to the shaft diameter of the trunnion, and the ratio of the outer diameter of the small gear to the outer diameter of the large gear is 1:5-6.

[0018] The beneficial effects of the present invention are as follows: The present invention is arranged on one side of the converter's trunnion. When the trunnion rotates, the large gear rotates. When the large gear rotates, the pulley's small gear rotates. The small gear's rotation drives the rotating shaft. The rotating shaft's rotation drives the coupling. The encoder then collects coupling rotation data. The transmission from trunnion rotation to coupling rotation only involves one stage of rotational transmission, from the trunnion to the coupling. This minimizes data loss, and the converter inclination angle data ultimately measured by the encoder is highly accurate. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] It should be noted that in the description of this utility model, “upper”, “lower”, “top”, “bottom”, orientation or position relationship is based on the attached Figure 1Regarding the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0023] The rotating device of the converter includes a support ring mounted on the converter and a reducer assembly and an ear shaft assembly respectively arranged on both sides of the support ring. When the converter rotates, the reducer and the ear shaft also rotate at the same time, so the rotation inclination angle of the converter can be calculated by the number of rotations of the ear shaft.

[0024] In one embodiment, Figure 1 As shown, the converter inclination angle data acquisition device of this embodiment is arranged on one side of the converter's trunnion 100 and includes a large gear 200, a small gear 300 assembly, a coupling 400 and an encoder 500 for collecting rotation data of the coupling 400.

[0025] The large gear 200 is fixedly sleeved on the trunnion 100 of the converter. Specifically, the large gear 200 is arranged between the trunnion bearing seat 110 and the converter rotary joint 120. When the converter rotates, the axial rotation speed and number of rotations of the large gear 200 are the same as those of the trunnion 100.

[0026] In this embodiment, the pinion gear 300 assembly includes a pinion gear 300 , a first bearing seat 310 , a second bearing seat 320 , and a rotating shaft 330 .

[0027] The first bearing seat 310 and the second bearing seat 320 are both fixed to the ground. The second bearing seat 320 is located on the side of the first bearing seat 310 away from the trunnion bearing seat 110. One end of the rotating shaft 330 is rotatably mounted on the first bearing seat 310, and the other end of the rotating shaft 330 is rotatably mounted on the second bearing seat 320. The pinion 300 is fixedly sleeved on the rotating shaft 330. The axis of the rotating shaft 330 is parallel to the axis of the trunnion 100. The pinion 300 meshes with the large gear 200.

[0028] The inner diameter of the large gear 200 is equal to the shaft diameter of the trunnion 100, and the ratio of the outer diameter of the small gear 300 to the outer diameter of the large gear 200 is 1:5 to 6. A bracket is set on the ground, and the first bearing seat 310 and the second bearing seat 320 are fixed to the ground through the bracket.

[0029] Specifically, when the ear shaft 100 rotates, the large gear 200 rotates synchronously, driving the small gear 300 meshing with it to rotate. The small gear 300 and the rotating shaft 330 are fixed, and the small gear 300 drives the rotating shaft 330 to rotate.

[0030] The coupling 400 is located on the side of the second bearing seat 320 away from the first bearing seat 310 and is fixedly connected to the transmission shaft. Under the action of the transmission shaft, the coupling 400 rotates synchronously with the pinion 300, ultimately transmitting the rotation data of the trunnion 100 to the coupling 400.

[0031] The encoder 500 is disposed at one end of the coupling 400 away from the first bearing seat 310 and is fixedly connected to the coupling 400. The encoder 500 can collect rotation data of the coupling 400 and convert the rotation data of the coupling 400 into rotation inclination data of the converter.

[0032] In addition, the converter inclination angle data acquisition device of this embodiment is also provided with a display, and the encoder 500 is connected to the display signal. The encoder 500 can send the converter rotation inclination angle data to the display for display to assist the operator in converter operation.

[0033] The converter inclination angle data acquisition device of this embodiment has a simple structure. The converter rotation inclination angle data is transmitted from the ear shaft 100 to the coupling 400 through only one level of rotation transmission, that is, the rotation transmission from the ear shaft 100 to the coupling 400. The degree of data loss reduction is low, and the converter inclination angle data finally measured by the encoder 500 is highly accurate.

[0034] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the scope of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
