[0003] The purpose of this invention is to provide a converter auxiliary lance device with a lightweight frame structure. By changing the lower part of the guide rail to a split structure, the structure is simplified, transportation costs and installation work are reduced, and the overall frame is made lighter by changing the cross-section of the rotating frame.

[0004] The technical solution adopted by this utility model to solve this technical problem is: a converter auxiliary lance device with a lightweight frame structure is provided, including a vertically arranged guide rail, a rotating frame fixed to the guide rail, an auxiliary lance rotating platform and a lower rotating fulcrum arranged at the upper end of the rotating frame;

[0005] The guide rail is divided in the middle and is composed of upper and lower sections. The guide rail includes a fixed frame, a track frame fixed to the fixed frame, and a track body fixed on the track frame. The fixed frame is shorter than the track frame, so that the lower parts of the fixed frame and the track frame together form a stepped structure.

[0006] The rotating frame has a triangular cross-section and includes a first vertical steel, a second vertical steel, a third vertical steel, and several horizontal steels for connecting the second vertical steel and the third vertical steel. The first vertical steel is connected to the second vertical steel and the third vertical steel by several connecting steels. The bottom end of the first vertical steel is provided with a support frame for connecting the lower rotation fulcrum and the fixed frame. The middle part of the support frame is connected to the fixed frame by a diagonal steel.

[0007] Preferably, in the converter auxiliary lance device with a lightweight frame structure, the fixed frame has a plurality of fixed plates on one side relative to the rotating frame, the fixed plates have a plurality of fixed plate through holes, and the horizontal steel has horizontal steel through holes that cooperate with the fixed plate through holes. The fixed plate through holes and the horizontal steel through holes are connected by bolts.

[0008] Preferably, in the converter auxiliary lance device with a lightweight frame structure, the auxiliary lance rotating platform is provided with an upper rotating fulcrum, and the lower rotating fulcrum is located at the top of the support frame corresponding to the position of the upper rotating fulcrum, with the rotation center axes of the upper rotating fulcrum and the lower rotating fulcrum coinciding.

[0009] Preferably, in the converter auxiliary lance device with a lightweight frame structure, the lower rotation fulcrum includes a bearing seat located at the top of the support frame, a spherical bearing fixed in the bearing seat, a pin shaft fitted in the spherical bearing, a pin shaft seat for fixing the pin shaft, and a fixed seat connected to the pin shaft seat.

[0010] Preferably, in the converter sub-lance device with a lightweight frame structure, the sub-lance rotating platform is provided with a lifting drive mechanism and a rotating drive mechanism, and the rotating drive mechanism is connected to the upper rotating fulcrum.

[0011] This utility model has at least the following beneficial effects:

[0012] 1. The lower part of the guide rail frame is changed to a split structure and the structure is simplified. The main reason is that the 24-meter frame would pose an excessive risk during overall transportation, and it is also inconvenient to transport in special road sections. This can reduce transportation costs and installation work.

[0013] 2. By changing the cross-section of some rotating frames and support frames, the overall frame can be made lighter.

[0014] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0022] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0024] like Figure 1-4 As shown, a preferred embodiment of the present invention provides a converter sub-lance device with a lightweight frame structure, including a vertically arranged guide rail 1, a rotating frame 2 fixed to the guide rail 1, a sub-lance rotating platform 3 disposed on the upper end of the rotating frame 2, and a lower rotating fulcrum 5.

[0025] The guide rail 1 is divided in the middle and is composed of upper and lower sections, which facilitates transportation. The guide rail 1 includes a fixed frame 15, a track frame 14 fixed to the fixed frame 15, and a track body 13 fixed on the track frame 14. The fixed frame 15 is shorter than the track frame 14, so that the lower parts of the fixed frame 15 and the track frame 14 together form a stepped structure. The lower part of the frame of the guide rail 1 is changed to a split structure, which simplifies the length of the fixed frame 15, reduces transportation costs and installation work.

[0026] The rotating frame 2 has a triangular cross-section and includes a first vertical steel 6, a second vertical steel 7, a third vertical steel 8, and several horizontal steels 9 for connecting the second vertical steel 7 and the third vertical steel 8. The first vertical steel 6 is connected to the second vertical steel 7 and the third vertical steel 8 by several connecting steels 10. The bottom end of the first vertical steel 6 is provided with a support frame 11 for connecting the lower rotation fulcrum 5 and the fixed frame 15. The middle part of the support frame 11 is connected to the fixed frame 15 by a diagonal steel 12, which makes the overall structure of the rotating frame 2 lightweight.

[0027] Furthermore, in the converter auxiliary lance device with a lightweight frame structure, the fixed frame 15 is provided with a plurality of fixed plates 16 on one side relative to the rotating frame 2. The fixed plates 16 are provided with a plurality of fixed plate through holes. The horizontal steel 9 is provided with horizontal steel through holes that cooperate with the fixed plate through holes. The fixed plate through holes and the horizontal steel through holes are connected by bolts, which precisely controls the splicing accuracy of the rotating frame 2 and the guide rail 1, while facilitating disassembly and fixing.

[0028] Furthermore, in the converter auxiliary lance device with a lightweight frame structure, the auxiliary lance rotating platform 3 is provided with an upper rotating fulcrum 4, and the lower rotating fulcrum 5 is located at the top of the support frame 11 corresponding to the position of the upper rotating fulcrum 4. The rotation center axes of the upper rotating fulcrum 4 and the lower rotating fulcrum 5 coincide, ensuring that the rotational movements of the upper and lower parts of the rotating frame 2 are consistent, thereby reducing the driving force of the rotating drive mechanism 23.

[0029] Furthermore, in the converter auxiliary lance device with a lightweight frame structure, the lower rotation fulcrum 5 includes a bearing seat 17 disposed at the top of the support frame 11, a spherical bearing 18 fixed within the bearing seat 17, a pin 19 fitted within the spherical bearing 18, a pin seat 20 for fixing the pin 19, and a fixing seat 21 connected to the pin seat 20. The fixing seat 21 is used to fix the device to the corresponding equipment.

[0030] Furthermore, in the converter auxiliary lance device with a lightweight frame structure, the auxiliary lance rotating platform 3 is provided with a lifting drive mechanism 22 and a rotating drive mechanism 23. The rotating drive mechanism 23 is connected to the upper rotating fulcrum 4 and drives the upper rotating fulcrum 4 to move.

[0031] The specific implementation is as follows: In this embodiment, a preferred implementation is that the secondary gun body is set on the track body 13, and a mobile trolley can be set at the lower part of the track frame 14. The mobile trolley is connected to the secondary gun body. The mobile trolley is driven to move up and down along the track body 13 by the guiding action of the lifting drive mechanism 22. The rotation drive mechanism 23 is used to drive the upper rotation fulcrum 4 to move, thereby driving the secondary gun rotation platform 3, the rotation frame 2 and the guide rail 1 to rotate on the horizontal plane, so as to realize the switching of the secondary gun body in the horizontal and vertical planes.

[0032] This invention simplifies the structure and reduces transportation costs and installation work by changing the lower part of the guide rail 1 to a split structure, and achieves the goal of lightweighting the overall frame by changing the cross-section of the rotating frame 2.

[0033] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
