Description

Technical Field

[0001] This utility model relates to the field of converter steelmaking, specifically to a compact telescopic transverse auxiliary lance. Background Technology

[0002] The converter auxiliary lance is a technical means of using a special probe tip to penetrate into the converter before the molten steel reaches its endpoint, to detect the relevant data status of the molten steel at the endpoint, and then feeding the results back to the overall control system for continuous correction and adjustment.

[0003] In the converter steelmaking process, the application of auxiliary lances improves the accuracy of temperature measurement and sampling, reduces the number of furnace turnings and the series of possible pollution, improves the endpoint prediction results, and greatly reduces the labor intensity of workers and improves the working environment, providing technical support for the intelligent development of "one-click steelmaking".

[0004] The newly built large converter was designed with sufficient space reserved for the installation of the auxiliary lance device. That is, during the design phase, a sufficient distance was reserved between the high-level frame platform of the converter and the oxygen lance platform to ensure that the oxygen lance and the auxiliary lance do not interfere with each other.

[0005] In response to the policy requirement of "one-click steelmaking," many older workshops with small converters urgently need to install auxiliary lances. However, due to the age of these small converter workshops, the need for auxiliary lance installation was not considered in the initial design. As a result, the distance between the converter platform and the oxygen lance platform is small (i.e., the oxygen lance atrium area is cramped), and the commonly used transverse auxiliary lances have huge transverse frames, making it impossible to directly install the auxiliary lances in this space. While existing solutions offer ideas for installing auxiliary lances in small converter workshops, they do not address the problems of the large size of the auxiliary lance equipment and the resulting overcrowding of equipment on the converter's upper frame and operating platform, hindering daily operation and maintenance. Utility Model Content

[0006] To address the aforementioned shortcomings of existing technologies, a compact telescopic lateral movement secondary gun is provided, which simplifies the structure, meets the requirement of installing a secondary gun in a confined space, and reduces costs.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: The compact telescopic transverse auxiliary lance is used in small converters in old factories. A high-rise frame platform and an oxygen lance platform are set above the small converter in the old factory, with an oxygen lance skylight area left between the two. It includes a traverse device and an auxiliary lance. The traverse device is installed on the upper frame platform of the converter and is arranged along the oxygen lance skylight area. The auxiliary lance is fixed on the movable part of the traverse device and slides along the oxygen lance skylight area with the movable part. The auxiliary lance includes an upper section, a lower section, and a telescopic device connecting the upper section and the lower section. A sliding cavity is provided in the upper section, and the telescopic device is placed in the sliding cavity. The bottom end of the telescopic device is connected to the top end of the lower section. A detection lance head is installed at the bottom end of the lower section. Under the action of the telescopic device, the lower section of the sub-gun extends out of the sliding cavity of the upper section of the sub-gun, or retracts into the sliding cavity of the upper section of the sub-gun.

[0008] According to the above technical solution, the transverse movement device includes a transverse movement track laid on the high-rise frame platform of the converter, a trolley body slidably connected to the transverse movement track, a transmission unit and a motor for driving the trolley body to move on the transverse movement track, and a cable reel on the trolley; the cable reel is used to wind up and unwind the external cable connected to the motor.

[0009] According to the above technical solution, the secondary gun, motor, and cable reel are arranged adjacent to each other on the trolley body along the length of the transverse track.

[0010] According to the above technical solution, the transmission unit adopts a gear and rack transmission pair; The transmission unit includes a rack arranged parallel to the transverse track and a gear meshing with the rack; the gear is rotatably connected to the trolley body and connected to the output shaft of the motor, and the motor is fixed to the trolley body; the rack is directly or indirectly fixed to the high-rise frame platform of the converter.

[0011] According to the above technical solution, the transmission unit adopts a lead screw and nut transmission pair; The transmission unit includes a lead screw arranged parallel to the transverse track, support seats located at both ends of the lead screw, and nuts rotatably connected to the lead screw; the nuts are fixed to the trolley body; the support seats are fixed to the high-level frame platform of the converter, and the two ends of the lead screw are rotatably connected to the support seats; the motor is directly connected to the lead screw, or a gear transmission assembly is provided, and the motor is connected to the lead screw through the gear transmission assembly.

[0012] According to the above technical solution, at least one transverse track is provided.

[0013] According to the above technical solution, a portion of the trolley body is suspended above the oxygen lance ceiling area, and the upper section of the auxiliary lance is fixed to the suspended part of the trolley body; an opening is provided at the top of the sliding cavity of the upper section of the auxiliary lance, and a mounting bracket is provided on the trolley body; the top of the telescopic device is fixed on the mounting bracket, and the bottom of the telescopic device extends into the sliding cavity of the upper section of the auxiliary lance and connects to the lower section of the auxiliary lance.

[0014] According to the above technical solution, a mounting groove is provided at the top of the lower section of the sub-gun, and a slot is provided on the side wall of the mounting groove; a steel pin matching the slot is provided at the bottom of the telescopic device, and the steel pin is placed in the slot.

[0015] According to the above technical solution, the telescopic device adopts a hydraulic cylinder or an electric cylinder.

[0016] This utility model has the following beneficial effects: 1. The auxiliary gun is configured as an upper section and a lower section, with the lower section slidably connected to the upper section via a telescopic device. The auxiliary gun is moved to the measuring position by a lateral movement device, and the telescopic device drives the lower section downwards until it is fully extended, at which point it is inserted into the converter for temperature measurement and sampling. After temperature measurement and sampling, the telescopic device drives the lower section upwards until the bottom of the auxiliary gun is above the converter opening; subsequently, the lateral movement device carries the auxiliary gun laterally to the standby position, where an external probe collection device removes the probe from the bottom of the auxiliary gun and replaces it with a new probe. In this application, the auxiliary gun is configured as two sections, and the telescopic device is installed in the sliding cavity of the upper section. Compared to existing technologies, this application eliminates the external lifting track frame, the lifting track, and the lower lateral movement track, significantly simplifying the structure of the auxiliary gun and reducing the space required for its installation. In addition, the drive unit of the sub-lance is located on the upper part of the sub-lance, close to the traverse device, which facilitates daily maintenance by personnel. The sub-lance only needs to go to the floor where the traverse trolley is located, without having to travel back and forth between the floors of the converter's high-rise frame, thus reducing the labor intensity of the operators.

[0017] 2. The auxiliary gun, motor, and cable reel are arranged adjacent to each other on the trolley body along the length of the transverse track. This avoids the auxiliary gun, motor, and cable reel being arranged on the trolley body along the width of the transverse track, making the arrangement more compact and reducing the lateral volume of the transverse device, thus further meeting the requirement of installing the auxiliary gun in a confined space; that is, the width of the transverse device is reduced.

[0018] This invention can significantly reduce the space occupied by the secondary weapon, achieving a truly "compact" secondary weapon.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] Reference Figures 1-4As shown, the compact telescopic transverse auxiliary lance provided by this utility model is applied to a small converter in an old factory building. A high-level frame platform 1 and an oxygen lance platform 2 are provided above the small converter in the old factory building, with an oxygen lance skylight area 3 left between them.

[0026] Example 1 The compact telescopic lateral sub-lance includes a lateral movement device 4 and a sub-lance 5. The lateral movement device is installed on the high-rise frame platform of the converter and is arranged along the oxygen lance skylight area. The sub-lance is fixed on the movable part of the lateral movement device and slides along the oxygen lance skylight area with the movable part. The sub-lance includes an upper sub-lance section 5-1, a lower sub-lance section 5-2, and a telescopic device 5-3 connecting the upper and lower sub-lance sections. A sliding cavity is provided in the upper sub-lance section, and the telescopic device is placed in the sliding cavity. The bottom end of the telescopic device is connected to the top end of the lower sub-lance section. A detection gun head is installed at the bottom end of the lower sub-lance section. Under the action of the telescopic device, the lower section of the sub-gun extends out of the sliding cavity of the upper section of the sub-gun, or retracts into the sliding cavity of the upper section of the sub-gun.

[0027] In this design, the sub-gun consists of an upper section and a lower section, with the lower section slidably connected to the upper section via a telescopic device. A lateral movement device carries the sub-gun to the measurement position, while the telescopic device moves the lower section downwards until it is fully extended, at which point it is inserted into the converter for temperature measurement and sampling. After temperature measurement and sampling, the telescopic device moves the lower section upwards until the bottom of the sub-gun is above the converter opening; subsequently, the lateral movement device carries the sub-gun laterally to the standby position, where an external probe collection device removes the probe from the bottom of the sub-gun and replaces it with a new one. In this application, the sub-gun is divided into two sections, and the telescopic device is installed within the sliding cavity of the upper section. Compared to existing technologies, this design eliminates the need for an external lifting track frame, lifting track, and lower lateral movement track, significantly simplifying the sub-gun's structure and reducing the space required for its installation. In addition, the drive unit of the sub-lance is located on the upper part of the sub-lance, close to the traverse device, which facilitates daily maintenance by personnel. The sub-lance only needs to go to the floor where the traverse trolley is located, without having to travel back and forth between the floors of the converter's high-rise frame, thus reducing the labor intensity of the operators.

[0028] Example 2 Based on Embodiment 1, a preferred structural form of the transverse movement device is provided. The transverse movement device includes a transverse track 4-1 laid on the high-level frame platform of the converter, a trolley body 4-2 slidably connected to the transverse track (the trolley body is a movable part, and the auxiliary lance is fixedly installed on the trolley body), a transmission unit and a motor 4-3 for driving the trolley body to move on the transverse track, and a cable reel 4-4 provided on the trolley; the cable reel is used to wind up and unwind the external cable connected to the motor.

[0029] Driven by a motor and transmission mechanism, the trolley moves laterally along the transverse track. The direction of movement of the trolley can be changed by controlling the forward and reverse rotation of the motor.

[0030] The auxiliary gun, motor, and cable reel are arranged adjacent to each other on the trolley body along the length of the transverse track. This avoids increasing the volume of the trolley body and making it impossible to install the auxiliary gun in a confined space if the auxiliary gun, motor, and cable reel were arranged along the width of the transverse track.

[0031] Based on Example 2, two layout configurations of the transverse movement device are presented. First, the transmission unit adopts a gear and rack transmission pair; The transmission unit includes a rack arranged parallel to the transverse track and a gear meshing with the rack; the gear is rotatably connected to the trolley body and connected to the output shaft of the motor, and the motor is fixed to the trolley body; the rack is directly or indirectly fixed to the high-rise frame platform of the converter.

[0032] In this application, the rotation of the gear driven by the motor, and the movement of the gear on the rack, drives the trolley body to move on the transverse track, thereby achieving the purpose of changing the position of the secondary gun.

[0033] Secondly, the transmission unit adopts a lead screw and nut transmission pair; The transmission unit includes a lead screw that is parallel to the transverse track and flush at both ends, support seats located at both ends of the lead screw, and nuts rotatably connected to the lead screw; the nuts are fixed to the trolley body; the support seats are fixed to the high-level frame platform of the converter, and the two ends of the lead screw are rotatably connected to the support seats; the motor is directly connected to the lead screw, or a gear transmission assembly is provided, and the motor is connected to the lead screw through the gear transmission assembly.

[0034] In this application, since the trolley body can only move in a straight line on the transverse track, the transverse track serves as a guide; when the motor drives the lead screw to rotate, the nut moves the trolley body along the length of the transverse track, thereby achieving the purpose of changing the position of the auxiliary gun.

[0035] In embodiments 1 and 2, at least one transverse track is provided.

[0036] In embodiments 1 and 2, a portion of the trolley body is suspended over the oxygen lance ceiling area, and the upper section of the auxiliary lance is fixed to the suspended portion of the trolley body; an opening is provided at the top of the sliding cavity of the upper section of the auxiliary lance, and a mounting bracket is provided on the trolley body; the top of the telescopic device is fixed to the mounting bracket, and the bottom of the telescopic device extends into the sliding cavity of the upper section of the auxiliary lance and connects to the lower section of the auxiliary lance.

[0037] Alternatively, the top of the sliding cavity in the upper section of the secondary gun can be left unopened, with the top of the telescopic device fixedly mounted on the top of the sliding cavity. An opening can be made in the side wall of the sliding cavity for threading conduits. This arrangement makes maintenance of the telescopic device inconvenient.

[0038] In embodiments 1 and 2, a connection form between the lower section of the sub-gun and the telescopic device is given. The top end of the lower section of the sub-gun is provided with a mounting groove 5-4, and the side wall of the mounting groove is provided with a locking groove 5-5. The bottom end of the telescopic device is provided with a steel pin 5-6 that matches the locking groove, and the steel pin is placed in the locking groove.

[0039] In embodiments 1 and 2, the telescopic device employs a hydraulic cylinder or an electric cylinder.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
