Description

Technical Field

[0001] This utility model relates to the field of iron and steel metallurgy technology, and in particular to a high load-bearing frame for steel ladle cars. Background Technology

[0002] In modern steel production processes, the transportation and turnover of molten steel are crucial. Traditional methods of molten steel transportation are inefficient and unsafe, making it difficult to meet the demands of large-scale, high-intensity production. Steel ladle cars have emerged to address this need. They are specifically designed for the safe and efficient transportation of molten steel ladles within steelmaking workshops. Equipped with a high-power drive system, they can carry several tons or even tens of tons of molten steel, moving smoothly and precisely stopping at various workstations. Their advanced braking and protective devices effectively prevent molten steel spillage, significantly improving transportation safety. Compared to the past, steel ladle cars have significantly improved the efficiency of molten steel transportation and reduced labor costs, becoming an indispensable key piece of equipment for steel enterprises and powerfully driving the modernization of the steel industry.

[0003] In the existing technology, a small slag pot is installed on the ladle car for use as a container for slag overflow and slag collection during converter tapping. Currently, with the continuous increase in rated load capacity of ladle cars, the slag capacity is getting larger and larger, and the small slag pot can no longer meet the needs of ladle cars with larger slag capacity. The small slag pot cannot hold all the steel slag, so the slag pot needs to be replaced multiple times, and the replacement time is long, which reduces production efficiency. On the other hand, replacing it with a large-capacity slag pot will cause one side of the ladle car to bear a large weight, which is not conducive to the overall operation of the ladle car.

[0004] To address the aforementioned issues, an existing patent (publication number: CN221018659U) proposes a high-load-bearing frame for ladle cars. A ladle smelting container is positioned in the middle of the car frame to hold molten steel for continuous casting and rolling processes. Two slag trays, located on either side of the ladle smelting container, are mounted on the car frame, serving as slag containers. This invention employs a double slag container structure, located on either side of the ladle smelting container. This solves the problem of small slag pots being unable to hold all the slag, requiring frequent slag pot replacements and avoiding frequent slag pot changes that impact production efficiency. Furthermore, the slag container in this ladle car is optimized from a slag pot to a slag tray, which offers better stability. For the same volume, the height of the slag tray is lower than that of the slag pot, making slag emptying and cleaning easier and solving the problem of difficult slag pot cleaning. This also addresses the issues of existing traditional ladle cars lacking slag containers or having limited slag capacity and volume.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the existing high-load-bearing frames for steel ladle cars have poor adaptability. When the transportation demand is large, they cannot be flexibly adjusted according to the size of the steel ladle, resulting in rigid installation and transportation efficiency, as well as inconvenience in disassembly and assembly. After forming, they are difficult to disassemble and adjust, making subsequent use and operation difficult and consuming manpower and time costs.

[0006] To address this, a high load-bearing frame for steel-clad vehicles is proposed. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high load-bearing frame for steel ladle cars, comprising a load-bearing body, wherein a convenient fixing mechanism is movably connected to the inner side of the top of the load-bearing body, and a reinforcing mechanism is movably connected to the top of the load-bearing body;

[0009] The convenient fixing mechanism includes a positioning groove, a supporting circular plate, a fixing clamp, and a fixing component.

The fixing clamp is slidably connected to the inner side of the supporting circular plate and is movably connected to the inner side of the vehicle body. The fixing component is movably connected to the inner side of the positioning groove and to the bottom of the supporting circular plate.

[0014] Preferably, the sliding block is fixedly connected to the bottom of the fixed clamping block, the sliding block is movably connected to the inner side of the arc-shaped groove, the arc-shaped groove is opened on the inner side of the guide plate, the guide plate is movably connected to the inner side of the positioning groove, the guide plate is fixedly connected to the output end of the servo motor, the servo motor is fixedly connected to the bottom of the inner side of the bearing base box, the bearing base box is fixedly connected to the bottom of the bearing vehicle body, and the bearing base box is set at the bottom of the positioning groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application solves the problem of poor adaptability of existing high-load-bearing frames for ladle cars by setting up a convenient fixing mechanism.

It can be flexibly adjusted during transportation to adapt to different sizes of ladles, improve the efficiency of installation, fixing and transportation, and facilitate disassembly and assembly, reduce the difficulty of subsequent use and operation, and save manpower and time costs.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A high load-bearing frame for steel-clad vehicles includes a load-bearing body 1, a convenient fixing mechanism 2 movably connected to the inner side of the top of the load-bearing body 1, and a reinforcing mechanism 3 movably connected to the top of the load-bearing body 1.

[0029] The convenient fixing mechanism 2 includes a positioning groove 21, a supporting circular plate 22, a fixing clamp 23, and a fixing component 24. The positioning groove 21 is opened on the inner side of the top of the carrier vehicle body 1. The supporting circular plate 22 is fixedly connected to the inner side of the positioning groove 21. The fixing clamp 23 is slidably connected to the inner side of the supporting circular plate 22 and is movably connected to the inner side of the carrier vehicle body 1. The fixing component 24 is movably connected to the inner side of the positioning groove 21 and is movably connected to the bottom of the supporting circular plate 22.

[0030] In this embodiment: the positioning groove 21 can be used to position the ladle, the supporting circular plate 22 can support the ladle and the fixing clamp 23, and the fixing component 24 can drive the fixing clamp 23 to clamp the ladle inward at the same time, thereby achieving the effect of convenient installation and adapting to different models of ladle.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the reinforcement mechanism 3 includes a triangular support frame 31, a clamping round frame 32, a connecting rod 33, a pull rod 34, a connecting plate 35, and a hydraulic cylinder 36.

[0032] Specifically, such as Figure 1 , Figure 2 , Figure 5As shown, the triangular support 31 is slidably connected to the top of the carrier body 1, the clamping round frame 32 is fixedly connected to the outside of the triangular support 31, the linkage rod 33 is fixedly connected to the outside of the triangular support 31, and the linkage rod 33 is slidably connected to the top of the carrier body 1.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the tie rod 34 is rotatably connected to the outside of the linkage rod 33, the tie rod 34 is rotatably connected to the outside of the linkage plate 35, the hydraulic cylinder 36 is fixedly connected to the bottom of the linkage plate 35, and the hydraulic cylinder 36 is fixedly connected to the top of the carrier vehicle body 1.

[0034] In this embodiment: by activating the hydraulic cylinders 36 on the top of both sides of the load-bearing vehicle body 1, the hydraulic cylinders 36 lift up and drive the connecting plate 35 to rise. The pull rods 34 on both sides of the connecting plate 35 rotate downward, pulling the other end of the connecting plate 35 to slide inward, thereby driving the triangular support frame 31 and its outer clamping round frame 32 to move inward, so that the steel ladle is in the center of the two sets of clamping round frames 32. By the elastic filling sleeve 5 on the inner side of the clamping round frame 32 pressing and adhering, the two sets of triangular support frames 31 are stabilized on both sides of the steel ladle. This design abandons the integrated high load-bearing frame and uses a method of separately driving the fixed clamping block 23 and the triangular support frame 31 to clamp and fix the steel ladle.

[0035] Specifically, such as Figure 3 , Figure 4 As shown, the fixed assembly 24 includes a sliding block 24a, a guide plate 24b, an arc groove 24c, a servo motor 24d, and a support base box 24e.

[0036] Specifically, such as Figure 3 , Figure 4 As shown, the sliding block 24a is fixedly connected to the bottom of the fixed clamping block 23, the sliding block 24a is movably connected to the inner side of the arc groove 24c, the arc groove 24c is opened inside the guide plate 24b, the guide plate 24b is movably connected to the inner side of the positioning groove 21, the guide plate 24b is fixedly connected to the output end of the servo motor 24d, the servo motor 24d is fixedly connected to the bottom of the inner side of the bearing base box 24e, the bearing base box 24e is fixedly connected to the bottom of the bearing vehicle body 1, and the bearing base box 24e is set at the bottom of the positioning groove 21.

[0037] In this embodiment: by activating the servo motor 24d inside the support box 24e at the bottom of the vehicle body 1, the guide plate 24b connected to the output end of the servo motor 24d rotates immediately. Multiple sets of sliding blocks 24a on the inner side of the guide plate 24b slide along the arc groove 24c, driving the fixing block 23 on the top of the sliding block 24a to move inward synchronously on the inner side of the support circular plate 22, so that the fixing block 23 contacts and fixes the bottom of the ladle. The outer side of the fixing block 23 has an elastic clamping soft pad 4, which can deform according to the shape of the ladle, increase the friction, and ensure that the ladle is stably placed in the positioning groove 21.

[0038] Specifically, such as Figure 3 As shown, an elastic clamping pad 4 is movably connected to the outer side of the fixed clamping block 23.

[0039] Specifically, such as Figure 1 , Figure 2 As shown, the inner side of the clamping round frame 32 is movably connected with an elastic filling sleeve 5.

[0040] In this embodiment, the elastic clamping pad 4 and the elastic filling sleeve 5 can increase the clamping friction when clamping different types of steel ladles and adapt to the deformation of different steel ladle shapes.

[0041] Working principle: When transferring molten steel, a crane or other equipment is used to lift the sealed ladle containing molten steel and place it on the support circular plate 22 inside the positioning groove 21 of the ladle car body 1. After it is placed securely, the servo motor 24d inside the bottom of the carrier body 1 and the carrier base box 24e is started. The guide plate 24b connected to the output end of the servo motor 24d rotates. Multiple sets of sliding blocks 24a inside the guide plate 24b slide along the arc groove 24c, driving the fixing blocks 23 on the top of the sliding blocks 24a to move inward simultaneously inside the support circular plate 22. This causes the multiple sets of fixing blocks 23 to contact the bottom of the ladle and fix it. The outer side of the fixing blocks 23 is provided with elastic clamping pads 4, which can deform according to the different shapes of the ladle to increase friction and ensure that the ladle is stable in the positioning groove 21. After the fixing blocks 23 are fixed, the ladle is secured. After completion, the hydraulic cylinders 36 on both sides of the top of the load-bearing vehicle body 1 are activated. The hydraulic cylinders 36 lift up the connecting plate 35, and the pull rods 34 on both sides of the connecting plate 35 rotate downward, pulling the other end of the connecting plate 35 to slide inward. The connecting plate 35 drives the triangular support frame 31 and its outer clamping round frame 32 to move inward, so that the steel ladle is in the center position of the two sets of clamping round frames 32. Through the compression and adhesion of the elastic filling sleeve layer 5 on the inner side of the clamping round frame 32, the two sets of triangular support frames 31 are stably set on both sides of the steel ladle, further reinforcing it. The integrated high load-bearing frame can be abandoned. The steel ladle is clamped and fixed by driving the fixed clamping block 23 and the triangular support frame 31 respectively. Compared with the traditional integrated design, the system is more flexible, can adapt to different models of steel ladles, and is more convenient to disassemble and replace, while ensuring the stability of transportation.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
