Description

Technical Field

[0001] This invention relates to the field of steel ladle transport equipment technology, and in particular to a steel ladle bearing and shifting device. Background Technology

[0002] When a ladle needs hot repair, it is generally necessary to use an overhead crane to lift the ladle to the repair position, and then lay the ladle horizontally on the ground support for repair. Since the lifting and tilting of the ladle both depend on the overhead crane, the repair position must be arranged in the same span as the overhead crane used for transferring the ladle. This results in a long crane travel distance and a high overhead crane occupancy rate, which is not conducive to the efficient operation of the site.

[0003] To address the aforementioned issues, Chinese invention patent application number 202510634551.1 discloses a ladle tilting transport vehicle and a hot repair method. The disclosed ladle tilting transport vehicle includes a vehicle body, a tilting saddle, and a boom cylinder. The vehicle carries and moves the ladle. During use, the ladle is placed on the tilting saddle. Before hot repair, the tilting saddle is tilted by controlling the extension of the inclined boom cylinder. While this solution reduces the use of overhead cranes, overcomes the drawback of long lifting distances, and improves work efficiency, it still suffers from the following problems due to its structural limitations:

[0004] Due to the structure of the tilting saddle, it can only be used with one or a few types of steel ladles, resulting in poor applicability.

[0005] Because the tilting saddle is used to position the ladle, the ladle placed on the tilting saddle can only rotate at a small angle, and the angle of rotation cannot exceed 90 degrees. Otherwise, the safety risk is too high, which is not conducive to the safe and efficient operation of subsequent work after the ladle is tilted (cleaning, hot repair and spraying of anti-stick coating, etc.).

[0006] Therefore, there is a need for a highly adaptable ladle-carrying and shifting device that can flexibly adjust the ladle's posture as needed after bearing it, has low safety risks during use, and can assist in cleaning, hot repair, and spray coating operations. Summary of the Invention

[0007] This application provides a ladle-bearing and shifting device, which solves the technical problems of existing ladle-bearing and shifting devices, such as poor applicability, limited rotation angle (not exceeding 90 degrees), high safety risks, and inefficiency in subsequent operations after ladle tipping. It achieves the technical effects of strong applicability, flexible adjustment of ladle posture as needed after bearing the ladle, low safety risks, and efficient assistance in cleaning, hot repair, and coating operations.

[0008] This application provides a ladle bearing and shifting device, including a base car traveling along a track, and also including a rotating platform, a top bearing platform, a ladle bearing frame, a pushing rotating component, and a lifting rotating component;

[0009] The rotating platform is a vertically placed cylindrical rigid turntable, positioned on top of the base vehicle;

[0010] The top support platform is generally rectangular in shape, and its bottom is fixed to the top of the rotating platform;

[0011] The ladle support frame is used to support the ladle. There are two of them, symmetrically arranged and positioned on the top of the top support platform. The distance between them is adjustable and they are located directly above the rotating platform. The two ladle support frames work together to support one ladle. The ladle support frame includes a rigid frame for supporting the trunnion and a liftable frame for supporting the ladle seat. In use, the ladle is supported by the liftable frame before it is detached from the lifting device. The support for the ladle seat is released before the ladle needs to be tilted.

[0012] The pushing and rotating component is slidably positioned on the top bearing platform. When it moves, it abuts against and pushes the side wall of the steel ladle carried by the steel ladle bearing and shifting device to make it rotate.

[0013] The lifting and rotating assembly is used to push the steel ladle, which has been pushed to an inclined state by the pushing and rotating assembly, in the vertical direction and make it continue to rotate. The whole is a vertical telescopic rod.

[0014] Furthermore, the top surface of the top support platform is provided with a guide groove for guiding the movement direction of the rotating component, and also with a channel hole for the lifting rotating component to extend out.

[0015] The guide groove is a horizontally placed straight groove, and its length direction is the same as that of the top support platform.

[0016] The channel hole is positioned near the center of the top bearing platform, and the distance between the axis of the hole and the axis of the rotating platform is greater than 1.3 meters and less than 3 meters.

[0017] Furthermore, the steel ladle support frame includes a base block, a vertical frame, a lifting block, and a bottom support assembly;

[0018] The base block is a horizontally placed rigid rectangular block, with its bottom positioned on the top surface of the top bearing platform;

[0019] The vertical frame is a rigid frame that is placed vertically. It is a vertical rectangular strip and has a trunnion support groove at the top for limiting and supporting the trunnions of the ladle.

[0020] The lifting block is a vertically placed rectangular rigid block with a flat top surface. It slides and is positioned on the side wall of the vertical frame along the height direction of the vertical frame. When in use, its top surface is used to support the bottom plane of the ladle seat.

[0021] The bottom support assembly is a vertical rigid telescopic rod that drives the lifting block to rise and fall during extension and retraction.

[0022] Furthermore, the pushing and rotating assembly includes a pushing and shifting vehicle, a transverse column, and a vehicle drive assembly;

[0023] The pushing and shifting vehicle is a mobile trolley with a height greater than 70 cm, which moves along the guide groove and is generally a horizontally placed rectangular strip.

[0024] The transverse column is a rigid cylindrical object arranged horizontally, with its axial direction aligned with the length of the push-shifting vehicle. It rotates around its own axis and is connected to the top of the push-shifting vehicle, serving to transmit thrust and reduce friction. When the push-rotating assembly contacts the ladle, the outer wall of the transverse column will contact the ladle first.

[0025] Furthermore, the rotating platform has a built-in space for accommodating the lifting and rotating assembly, and the top of this space is connected to the channel hole;

[0026] The lifting and rotating assembly includes a vertical telescopic assembly and a top contact assembly positioned on top of the vertical telescopic assembly; the vertical telescopic assembly is a vertically arranged rigid telescopic rod, and after it is extended to its limit, the tilt angle of the steel ladle carried by the ladle bearing displacement device is greater than 90 degrees.

[0027] The main body of the top contact assembly is a horizontally placed cylindrical wheel, which is used to transmit force and reduce the wear of the ladle on the steel ladle when the vertical telescopic assembly pushes it.

[0028] Preferably, the overhead crane or top support platform is equipped with a laser emitter capable of emitting visible laser light. When hoisting the steel ladle, the laser emitted by the laser emitter assists in the positioning of the steel ladle, improving transportation efficiency and preventing tilting during placement.

[0029] Preferably, the top bearing platform is provided with two limiting grooves;

[0030] The limiting groove is a long, straight groove with its width direction being the same as the width direction of the top bearing platform, serving as a guide rail;

[0031] The two ladle support frames are slidably positioned on the two limiting grooves; when it is necessary to support ladles of different specifications, the ladle support frames are pushed to move along the limiting grooves to adapt to ladles of different specifications.

[0032] Preferably, it also includes a carrier shifting assembly;

[0033] The carrier shifting assembly includes a horizontal telescopic rod, a combination piece, and a combination body;

[0034] There are two horizontal telescopic rods, which are rigid telescopic rods arranged laterally and are controlled to extend and retract; the two horizontal telescopic rods are located on both sides of the push-shift vehicle and are partially inserted into the push-shift vehicle;

[0035] The combined piece is a vertically arranged rigid piece, there are two of them, one for each of the horizontal telescopic rods, and they are fixed to the end of the horizontal telescopic rod away from the pushing and moving vehicle, and are matched with the combined body;

[0036] The assembly is a rigid block or a vertically placed rigid plate with grooves for inserting the assembly pieces; there are two assemblies, which are fixed on opposite sides of two base blocks respectively.

[0037] After the assembly piece is inserted into the assembly body, the extension and retraction of the horizontal telescopic rod can drive the steel ladle support frame to move laterally.

[0038] Preferably, it also includes a cleaning component; the cleaning component includes a vehicle body scraper, an insert crossbar, and a bar scraper;

[0039] The vehicle body scraper is a horizontally placed rigid strip scraper, fixed on the side wall of the pushing and moving vehicle near the bottom, and the bottom contour matches the bottom contour of the guide groove.

[0040] The push-and-shift vehicle is provided with an insertion slot on each side near the bottom; the insertion slot is used for inserting the crossbar and the scraper on the bar.

[0041] The insertion crossbar is a horizontally placed rigid square bar; the insertion crossbar is slidably positioned in the insertion slot, and the end away from the insertion slot is fixed to the horizontal telescopic bar, changing the insertion amount as the horizontal telescopic bar extends and retracts; the bar scraper is a horizontally placed rigid strip scraper, fixed on the side wall of the insertion crossbar near the bottom, inclined, and the bottom end always abuts against the top surface of the top bearing platform.

[0042] Preferably, before pushing the scraped debris down, the top support platform is rotated so that the scraped debris is pushed to one side of the track.

[0043] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0044] By installing two movable ladle support frames on a railcar, the ladle to be handled is positioned using the ladle seats and trunnions of the ladle. The angle of the ladle is flexibly changed through a combination of pushing and lifting. This effectively solves the technical problems of existing ladle support and displacement devices, such as poor applicability, limited rotation angle (not exceeding 90 degrees), high safety risks, and difficulties in efficient follow-up operations after ladle tipping. This results in a ladle support and displacement device with strong applicability, flexible adjustment of the ladle's posture as needed after loading, low safety risks, and efficient assistance in cleaning, hot repair, and coating operations.

[0058] Example 1

[0059] like Figures 1 to 5 As shown, the ladle carrying and shifting device of this application moves along the track 001 to carry and move the ladle 003 for cleaning, hot repair and spraying of anti-stick coating on the ladle 003. It includes a base carrier 100, a rotating platform 200, a top carrying platform 300, a ladle carrying frame, a pushing rotating component, a lifting rotating component, a power component and a control unit.

[0060] The basic carrier 100 is a horizontally mounted track slab vehicle with a built-in power system and bottom wheels 110. It travels along track 001 under the coordinated control of the power components and control unit.

[0061] The rotating platform 200 is a vertically placed cylindrical rigid turntable, positioned on top of the base vehicle 100. It rotates under the coordinated control of the power assembly and the control unit to drive the top support platform 300 to rotate.

[0062] The top support platform 300 is a horizontally set plate-shaped platform with an overall rectangular plate shape. Its bottom is fixed to the top of the rotating platform 200, and it rotates relative to the base vehicle 100 and the ground under the drive of the rotating platform 200.

[0063] The top surface of the top support platform 300 is provided with a guide groove 310 for guiding the movement direction of the push rotating component, and also with a channel hole 330 for allowing the lifting rotating component to extend.

[0064] The guide groove 310 is a horizontal straight groove, and its length direction is the same as that of the top bearing platform 300.

[0065] The channel hole 330 is positioned near the center on the top bearing platform 300, and the distance between the axis of the hole and the axis of the rotating platform 200 is greater than 1.3 meters and less than 3 meters.

[0066] The ladle support frame is used to support the ladle 003. There are two of them, which are symmetrically arranged and positioned on the top of the top support platform 300. The two are located directly above the rotating platform 200, and the length direction of the line connecting the two is the same as the width direction of the top support platform 300. The two ladle support frames work together to support one ladle 003.

[0067] The steel ladle support frame includes a base block 410, a vertical frame 420, a lifting block 430, and a bottom support assembly 440.

[0068] The base block 410 is a horizontally placed rigid rectangular block, with its bottom positioned on the top surface of the top bearing platform 300. It has multiple positioning points on the top bearing platform 300 to accommodate steel ladles 003 of different specifications.

[0069] The vertical frame 420 is a rigid frame that is vertically placed. It is generally a vertical rectangular strip and has a trunnion support groove 421 at the top for restricting and supporting the trunnion 032 of the ladle 003. The trunnion support groove 421 is a U-shaped notch at the top of the vertical frame 420, and its bottom is an arc that matches the outer wall of the trunnion 032. Due to the presence of the trunnion support groove 421, the vertical frame 420 is U-shaped near the top.

[0070] The lifting block 430 is a vertically placed rectangular rigid block with a flat top surface. It is slidably positioned on the side wall of the vertical frame 420 along the height direction of the vertical frame 420. When in use, its top surface is used to support the bottom plane of the ladle seat 031 of the ladle 003.

[0071] The bottom support component 440 is a vertical rigid telescopic rod, with its bottom fixed to the top of the base block 410 and its top fixed to the bottom of the lifting block 430. It extends and retracts under the coordinated control of the power component and the control unit, and during extension and retraction, it drives the lifting block 430 to rise and fall.

[0072] The two steel ladle support frames are symmetrically arranged, and the distance between the two lifting blocks 430 is smaller than the distance between the two vertical frames 420.

[0073] After the trunnion 032 of the ladle 003 is placed into the trunnion support groove 421, the distance between the bottom of the ladle 003 and the top surface of the top support platform 300 is at least greater than 50 cm.

[0074] The pushing and rotating component is slidably positioned on the guide groove 310 of the top bearing platform 300. When it moves, it abuts against and pushes the side wall of the ladle 003 carried by the ladle bearing and shifting device to make it rotate.

[0075] The push-rotation assembly includes a push-shift vehicle 510, a transverse column 520, and a vehicle drive assembly 530.

[0076] The push-shifting vehicle 510 is a mobile trolley with a height greater than 70 cm. It moves along the guide groove 310 and is generally a horizontally placed rectangular strip. Its length direction is the same as the width direction of the top support platform 300.

[0077] The transverse column 520 is a rigid cylinder arranged laterally, with its axial direction being the same as the length direction of the push-shift vehicle 510. It is rotatably connected to the top of the push-shift vehicle 510 around its own axis, and plays the role of transmitting thrust and reducing friction. When the push-rotation component contacts the ladle 003, the outer wall of the transverse column 520 will contact the ladle 003 first.

[0078] The vehicle drive assembly 530 is a winch structure, including two drums and at least one pull rope. The two drums are respectively positioned at or near the two ends of the top support platform 300, with their axial direction being the same as the width direction of the top support platform 300. They rotate under the coordinated control of the power assembly and the control unit, thereby driving the pull rope to move laterally. The pull rope is fixed to the push-shift vehicle 510. When the drums rotate, they drive the push-shift vehicle 510 to move laterally.

[0079] The rotating platform 200 has a built-in space for accommodating the lifting and rotating assembly. This space is preferably a vertically placed cylinder with its top connected to the channel hole 330.

[0080] The lifting and rotating assembly is used to push the steel ladle 003, which has been pushed to an inclined state by the rotating assembly, in the vertical direction and make it continue to rotate. The whole is a vertical telescopic rod, and the bottom is fixed to the inner bottom of the space inside the rotating platform 200. When the lifting and rotating assembly is extended, it protrudes from the space inside the rotating platform 200, passes through the channel hole 330 and then abuts against the side wall of the steel ladle 003 in the inclined state.

[0081] The lifting and rotating assembly includes a vertical telescopic assembly 610 and a top contact assembly positioned on top of the vertical telescopic assembly 610. The vertical telescopic assembly 610 is a vertically arranged rigid telescopic rod that extends and retracts under the coordinated control of the power assembly and the control unit. After it extends to its limit, the tilt angle of the ladle 003 carried by the ladle bearing and shifting device is greater than 90 degrees. The top contact assembly is used to transmit the force and reduce the wear of the ladle 003 when the vertical telescopic assembly 610 pushes the ladle 003. The top contact assembly is a horizontally placed rigid cylinder with its axial direction the same as the width direction of the top bearing platform 300. It is rotatably connected to the top of the vertical telescopic assembly 610 through a rigid bracket around its own axis.

[0082] Preferably, in order to increase the contact area between the top contact assembly and the side wall of the steel ladle 003, further facilitate the transmission of force and reduce damage, the top contact assembly includes a rotating support block 621 and a horizontal wheel 622; there are two rotating support blocks 621, which are vertical rigid plates and are triangular in shape; the two rotating support blocks 621 are located on both sides of the vertical telescopic assembly 610 near the top, and are rotatably connected to the vertical telescopic assembly 610, with the axial direction of the rotating shaft being the same as the width direction of the top bearing platform 300; The two horizontally positioned wheels 622 are cylindrical and their axial directions are the same as the width direction of the top support platform 300. Both wheels are rotatably connected at both ends to the opposite surfaces of the two rotating support blocks 621. The two horizontally positioned wheels 622 are always located at the top of the vertical telescopic assembly 610. When they come into contact with the side wall of the ladle 003, the horizontally positioned wheels 622 will contact the side wall of the ladle 003 first. A torsion spring is positioned at the connection point between the rotating support block 621 and the vertical telescopic assembly 610. The presence of the torsion spring ensures that the two horizontally positioned wheels 622 are at the same height under normal conditions.

[0083] The power assembly is used to provide power for the operation of each component of the ladle bearing and shifting device of this application, and the control unit plays the role of controlling the coordinated operation of each component of the ladle bearing and shifting device. Both are existing technologies and will not be described in detail here.

[0084] Before the ladle support and shifting device of this application supports the ladle 003, the top surface of the lifting block 430 is located near the trunnion support groove 421, and the rotating component is positioned near one end of the top support platform 300, with the lifting rotating component in a retracted state; the spacing between the ladle support frames is adapted to the ladle 003 to be supported; in use, the overhead crane, with the aid of a lifting device, lifts the ladle 003 and moves it directly above the ladle support and shifting device, and gradually places the ladle seat 031 of the ladle 003 on the top surface of the lifting block 430, so that the trunnion 032 of the ladle 003 is directly above the trunnion support groove 421, so that the lifting block 430 supports the ladle 003; then, the overhead crane lifting device is controlled to disengage from the trunnion 032; subsequently, the lifting block 430 is controlled to move downward, so that the trunnion 032 of the ladle 003 is directly above the trunnion support groove 421. 32 is inserted into the trunnion support groove 421 (the entire ladle 003 is lifted with the help of trunnion 032); the ladle carrying and shifting device is controlled to move the ladle 003 to the repair position; the lifting block 430 is continued to move down so that it does not affect the rotation of the ladle 003; then, the pushing and rotating component is controlled to move laterally, pushing the ladle 003 to rotate from the side; after the pushing and shifting vehicle 510 moves out of the area directly above the channel hole 330, the lifting and rotating component is controlled to extend and continue to push the ladle 003 to rotate; the extension and retraction of the lifting and rotating component and the rotation of the rotating platform 200 are controlled as needed to flexibly change the posture of the ladle 003 and assist in various operations of handling the ladle 003 (cleaning, hot repair, spraying coating, etc.); after use, the components of the ladle carrying and shifting device are reset.

[0085] Preferably, when the ladle 003 is supported by the lifting block 430, the lifting and rotating assembly can be controlled to extend and retract to assist the lifting block 430 in supporting the ladle 003 as needed.

[0086] The telescopic rods used in this application for tipping over the auxiliary steel ladle 003 are all vertically set, which results in less wear, greater stability, and a longer service life compared to telescopic rods that are set at an angle.

[0087] Preferably, the overhead crane or top support platform 300 is equipped with a laser emitter capable of emitting visible laser light. When hoisting the steel ladle 003, the laser emitted by the laser emitter can be used to assist in the positioning of the steel ladle 003, thereby improving transportation efficiency and preventing tilting during placement.

[0088] Preferably, the top support platform 300 is provided with two limiting grooves 320; the limiting grooves 320 are long straight grooves with the same width direction as the top support platform 300, and serve as guide rails; the two ladle support frames are slidably positioned on the two limiting grooves 320; when it is necessary to support ladles 003 of different specifications, the ladle support frames are pushed to move along the limiting grooves 320 to adapt to ladles 003 of different specifications.

[0089] Preferred, such as Figure 6As shown, since the ladle bearing displacement device of this application has the ability to move, in order to improve the comfort of the operators during the hot repair process, multiple heat insulation barriers 002 can be set at the repair position. After the hot repair process has been carried out for a period of time, the ladle 003 can be moved as needed to replace the barriers 002.

[0090] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0091] The steel ladle bearing displacement device of this application does not require modification of steel ladle 003 during use;

[0092] This application solves the technical problems of existing ladle bearing and shifting devices, such as poor applicability, limited rotation angle (not exceeding 90 degrees), high safety risks, and difficulty in efficiently carrying out subsequent operations after ladle tipping. It achieves the technical effects of a ladle bearing and shifting device with strong applicability, the ability to flexibly adjust the ladle's posture as needed after bearing it, low safety risks during use, and the ability to efficiently assist in cleaning, hot repair, and coating operations.

[0093] Example 2

[0094] To further improve the ease of use of the ladle support shifting device of this application, and to achieve automatic adjustment of the ladle support frame position thereby reducing the labor intensity of manual operation, this application embodiment adds a support frame shifting component based on the above embodiment, specifically:

[0095] like Figure 7 As shown, the carrier shifting assembly includes a horizontal telescopic rod 710, a combination piece 720, and a combination body 730;

[0096] There are two horizontal telescopic rods 710, which are rigid telescopic rods arranged horizontally and extend and retract under the coordinated control of the power component and the control unit. The horizontal telescopic rods 710 are located on both sides of the push-shift vehicle 510 and are partially inserted into the push-shift vehicle 510. The length direction is the same as the width direction of the top support platform 300.

[0097] The combined piece 720 is a vertically arranged rigid piece, there are two of them, corresponding one-to-one with the horizontal telescopic rod 710, and are fixed to the end of the horizontal telescopic rod 710 away from the pushing and shifting vehicle 510, and are matched with the combined body 730.

[0098] The assembly 730 is a rigid block or a vertically placed rigid plate, with a groove on one side for the insertion of the assembly piece 720. There are two assemblies 730, corresponding one-to-one with the ladle support frame, and they are fixed on opposite sides of the two base blocks 410 respectively. Before the ladle support and displacement device carries the ladle 003, the horizontal telescopic rod 710 is extended to an appropriate length and then the displacement vehicle 510 is pushed to move laterally so that the assembly piece 720 can be inserted into the assembly 730. After the assembly piece 720 is inserted into the assembly 730, the extension and retraction of the horizontal telescopic rod 710 can drive the ladle support frame to move laterally.

[0099] like Figure 8 As shown, considering that the ladle bearing displacement device still needs to be cleaned after hot repair, in order to further improve the ease of use of the ladle bearing displacement device of this application, it is preferred to also include a cleaning component; the cleaning component includes a vehicle body scraper 810, an insert crossbar 830, and a bar scraper 840;

[0100] The scraper 810 is a horizontally placed, rigid strip scraper, inclined in direction, with its length in the same direction as the width of the top support platform 300 and its length matching that of the pushing and shifting vehicle 510. It is fixed to the side wall of the pushing and shifting vehicle 510 near the bottom, and its bottom contour matches the bottom contour of the guide groove 310. When the pushing and shifting vehicle 510 moves, it simultaneously scrapes and cleans the guide groove 310 and the area near it, moving the pushing and shifting vehicle 510 closer to the top support platform 300. When the ladle 003 is at the edge of the 00, push the scraped debris down. Because the ladle 003 is located directly above the channel hole 330 during hot repair and the opening faces one end of the top support platform 300, the debris remaining after hot repair will concentrate near the opening of the ladle 003 and will be some distance away from the channel hole 330. Therefore, when using the scraper 810 to remove debris, the debris will not easily enter the channel hole 330. Under long-term use, only the channel hole 330 and the internal space of the rotating platform 200 need to be cleaned periodically.

[0101] The pushing and shifting vehicle 510 has an insertion slot 820 on each side near the bottom; the insertion slot 820 is used for inserting the insertion crossbar 830 and its rod scraper 840; the insertion crossbar 830 is a horizontally placed rigid square rod; the insertion crossbar 830 is slidably positioned in the insertion slot 820, and the end away from the insertion slot 820 is fixed to the horizontal telescopic rod 710, changing the insertion depth as the horizontal telescopic rod 710 extends and retracts; the rod scraper 840 is a horizontally placed rigid strip. The scraper, with the same length as the insertion crossbar 830, is fixed to the side wall of the insertion crossbar 830 near the bottom, and is set at an angle, with its bottom end always in contact with the top surface of the top support platform 300. After the hot repair is completed, by controlling the movement of the push-moving vehicle 510 in conjunction with the timely extension of the insertion crossbar 830, most of the debris accumulated on the top support platform 300 can be pushed down, thereby assisting the cleaning operation (assisting in most of the cleaning work and reducing the labor intensity and danger of the operators).

[0102] Preferably, before pushing the scraped debris down, the top support platform 300 is rotated so that the scraped debris is pushed to one side of the track 001.
