Description

Technical Field

[0001] This utility model relates to the field of ladle sand addition technology, and in particular to a ladle sand addition device. Background Technology

[0002] A ladle, or molten steel ladle, is used in steel mills and foundries to receive and pour molten steel before open-hearth furnaces, electric furnaces, or converters. During ladle operations, diversion sand is added. This diversion sand is a filling material used at the bottom nozzle of the ladle. Its core function is to guide the molten steel to flow out automatically by forming a controllable sintered layer at the nozzle, thereby improving steelmaking efficiency and safety.

[0003] Currently, when adding sand to a steel ladle, the ladle is usually lifted upright by a gantry, which makes it inconvenient to insert the sand adding pipe into the container. Furthermore, since the position of the sand adding pipe after insertion is often fixed, the discharge range is fixed, making it difficult for the sand to flow and distribute quickly, resulting in poor actual performance. Summary of the Invention

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a ladle sand-adding device that allows the sand to flow and distribute rapidly within the ladle by controlling the sand-adding pipe to be inserted quickly and conveniently.

[0005] The technical solution adopted in this utility model is as follows:

[0006] The present invention discloses a ladle sand-adding device, comprising a base, cylinders, a top seat, a fixed frame, a fixed frame drive assembly, a rotating mechanism, a sand storage tank, a guide pipe, and a sand-adding pipe. The cylinders are vertically arranged on the left and right sides of the upper surface of the base and are symmetrical to each other. The top seat is correspondingly arranged above the base, and the cylinder body is fixedly connected to the upper surface of the base, and the cylinder rod is fixedly connected to the lower surface of the top seat. A sliding cavity is opened in the middle of the upper surface of the top seat, and the fixed frame drive assembly is arranged in the sliding cavity. The fixed frame is arranged above the sliding cavity and is fixedly connected to the fixed frame drive assembly. The sand storage tank is connected to the top of the fixed frame through the rotating mechanism. The sand-adding pipe is vertically arranged in front of the top seat. The top end of the sand-adding pipe is connected to the bottom outlet end of the sand storage tank through the guide pipe.

[0007] Furthermore, the fixed frame drive assembly includes a slider, a threaded rod, and a first motor; the threaded rod is disposed inside the sliding cavity, and its front and rear ends are rotatably connected to the top seat via bearings; the slider is connected to the outside of the threaded rod by threaded engagement and is slidably connected to the sliding cavity; the top of the slider is fixedly connected to the middle of the lower surface of the fixed frame; the first motor is laterally fixedly connected to the middle of the rear end of the top seat, and its output end is coaxially fixedly connected to one end of the threaded rod.

[0008] Furthermore, the rotating mechanism includes a rotating rod, a support frame, a guide frame, a rotating handle, a second motor, and a guide post; the rotating rod is vertically positioned at the top center of the fixed frame, and its lower end is rotatably connected to the fixed frame; the support frame is positioned above the rotating rod, and its lower center is fixedly connected to the top of the rotating rod; the sand storage tank is positioned at the top of the support frame; the second motor is vertically fixedly connected to the rear center of the fixed frame; the guide frame is radially fixedly connected to the rear side of the rotating rod; the rotating handle is positioned below the guide frame, and one end of it is coaxially fixedly connected to the output end of the second motor, while the top of the other end is fixedly connected to a guide post; the guide post is correspondingly slidably fitted inside the guide frame.

[0009] Furthermore, the four corner areas of the base and the top seat are connected by guide components.

[0010] Furthermore, the guide assembly includes a support cylinder and a support column; the support cylinder is vertically fixed to a corresponding position on the upper surface of the base; the support column is vertically slidably fitted inside the support cylinder, and its top end is fixed to a corresponding position on the lower surface of the top seat.

[0011] Furthermore, the base has four corners on its lower surface equipped with casters.

[0012] Furthermore, handrails are provided on the left and right sides of the top seat.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By setting up cylinders and multiple sets of guide components, the top seat can drive the sand storage tank to rise and fall stably, thereby quickly adjusting the height of the sand adding pipe. Furthermore, the fixed frame drive component can drive the fixed frame to move back and forth, which in turn drives the sand storage tank to move back and forth, thereby quickly adjusting the front and back position of the sand adding pipe. With the cooperation of this structure, the sand adding pipe can be quickly and conveniently inserted into the ladle for sand adding operations.

[0015] By using a rotating mechanism between the fixed frame and the support frame, the sand storage tank can be driven to swing back and forth through the support frame, thereby controlling the swing of the sand adding pipe inside the ladle. This allows the sand to flow and distribute rapidly within the ladle, effectively ensuring the sand adding effect. Attached Figure Description

[0023] See appendix Figures 1-4 The present invention proposes a ladle sand adding device, which includes a base 1, a cylinder 2, a top seat 4, a fixing frame 7, a fixing frame drive assembly, a rotating mechanism, a sand storage tank 10, a guide pipe 11, and a sand adding pipe 12.

[0024] The system includes two cylinders 2, which are vertically arranged on the left and right sides of the upper surface of the base 1 and are symmetrical to each other. The top seat 4 is arranged parallel to each other above the base 1 at a certain distance, and the cylinder bodies of the two cylinders 2 are fixedly connected to the upper surface of the base 1, and the cylinder rods are fixedly connected to the lower surface of the top seat 4. A sliding cavity 5 is opened in the middle of the upper surface of the top seat 4 along the width direction, and a fixed frame drive assembly is arranged in the sliding cavity 5. The fixed frame 7 is arranged above the sliding cavity 5 and is fixedly connected to the fixed frame drive assembly. The sand storage tank 10 is rotatably connected to the top of the fixed frame 7 through a rotating mechanism. The sand adding pipe 12 is vertically arranged in front of the top seat 4. The top end of the sand adding pipe 12 is connected to the bottom outlet end of the sand storage tank 10 through a guide pipe 11. In this embodiment, a control valve 13 is provided at the end of the guide pipe 11 connected to the sand storage tank 10.

[0025] like Figure 2As shown, the fixed frame drive assembly includes a slider 6, a threaded rod 14, and a first motor 15; the threaded rod 14 is disposed inside the sliding cavity 5, and its front and rear ends are rotatably connected to the top seat 4 via bearings; the slider 6 is connected to the outside of the threaded rod 14 by threaded engagement and is slidably connected to the sliding cavity 5; the top of the slider 6 is fixedly connected to the middle of the lower surface of the fixed frame 7; the first motor 15 is laterally fixedly connected to the middle of the rear end of the top seat 4, and its output end is coaxially fixedly connected to the rear end of the threaded rod 14.

[0026] In this embodiment, the four corner areas of the base 1 and the top seat 4 are connected by guide components 3.

[0027] Specifically, the guide assembly 3 includes a support cylinder 300 and a support column 301; the support cylinder 300 is vertically fixed to a corresponding position on the upper surface of the base 1; the support column 301 is vertically slidably fitted inside the support cylinder 300, and its top end is fixed to a corresponding position on the lower surface of the top seat 4.

[0028] In use, the top seat 4 can be driven to move up and down by the cylinder 2. With the sliding and telescopic cooperation of the four sets of support cylinders 300 and support columns 301, the top seat 4 can drive the sand storage tank 10 to rise and fall stably. Then, the sand storage tank 10 can drive the sand adding pipe 12 to rise and fall through the guide pipe 11, so that the height position of the sand adding pipe 12 can be quickly adjusted. The threaded rod 14 is driven to rotate by the first motor 15, so that the threaded rod 14 drives the slider 6 to move in the sliding cavity 5. Then, the slider 6 can drive the fixed frame 7 to move back and forth, so that the fixed frame 7 can drive the sand storage tank 10 to move back and forth, thereby quickly adjusting the front and back position of the sand adding pipe 12. With the cooperation of this structure, the sand adding pipe 12 can be quickly and conveniently inserted into the ladle for sand adding operation.

[0029] like Figure 3 and Figure 4 As shown, the rotating mechanism includes a rotating rod 8, a support frame 9, a guide frame 16, a rotating handle 17, a second motor 18, and a guide post 19. The rotating rod 8 is vertically arranged at the top center of the fixed frame 7, and its lower end is rotatably connected to the fixed frame 7. The support frame 9 is a concave frame, which is arranged above the rotating rod 8, and its lower center is fixedly connected to the top of the rotating rod 8. The sand storage tank 10 is placed on the top of the support frame 9, and its bottom outlet is located inside the concave frame. The second motor 18 is vertically fixed to the rear center of the fixed frame 7 through a bracket with its output end facing upward. The guide frame 16 is radially arranged on one side of the rotating rod 8, and one end of it is fixedly connected to the rotating rod 8. The rotating handle 17 is arranged below the guide frame 16, and one end of the handle is coaxially fixedly connected to the output end of the second motor, while the top of the other end is fixedly connected to the guide post 19. The guide post 19 is slidably fitted inside the guide frame 16.

[0030] During sand addition, the second motor 18 can drive the rotating handle 17 to make circular motion. Then, the rotating handle 17 can drive the guide column 19 to slide back and forth in the guide frame 16, thereby causing the guide column 19 to drive the guide frame 16 to swing back and forth. This, in turn, causes the guide frame 16 to drive the rotating rod 8 to swing back and forth continuously. Then, the rotating rod 8 can drive the sand storage tank 10 to swing back and forth through the support frame 9, thereby controlling the sand addition pipe 12 to swing in the ladle. This allows the diverted sand to flow and distribute rapidly in the ladle, effectively ensuring the sand addition effect.

[0031] The length ratio of the guide frame 16 and the rotating handle 17 can be adjusted according to the actual situation, as long as the rotating handle 17 can drive the guide frame 16 to swing back and forth.

[0032] In this embodiment, four corner areas on the lower surface of the base 1 are provided with casters 101, which are omnidirectional wheels; handrails 401 are provided on the left and right sides of the top seat 4. The casters 101 and handrails 401 facilitate the pushing and pulling of the device.

[0033] Matters not covered in this utility model are common knowledge.

[0034] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
