Description

Technical Field

[0001] This utility model belongs to the field of casting technology, and in particular relates to a device for monitoring and early warning of the position of molten iron in a casting cavity. Background Technology

[0002] In the casting process, the filling of the mold cavity with molten iron plays a crucial role in the quality of the casting. Traditional casting processes mainly include two methods: pit casting and sand box casting.

[0003] Pit casting involves directly creating the mold cavity in a pit on the ground. However, during the molten iron pouring process, operators cannot visually observe the filling height of the molten iron in the mold cavity, which can lead to insufficient filling or overflow of the mold cavity. When the molten iron is insufficiently filled, the casting will have defects such as shrinkage cavities and porosity, which seriously affect the integrity and strength of the casting. On the other hand, molten iron overflowing the mold cavity not only wastes materials but may also cause safety accidents. Sand box molding involves creating a mold cavity within a movable sand box, which is then placed on casting equipment for pouring. However, sand box molding also faces the problem of difficulty in monitoring the molten iron position, as operators cannot directly see the actual position of the molten iron inside the mold cavity. In existing casting processes, although there are some simple monitoring methods, such as roughly judging the filling status of the mold cavity by observing the flow rate of molten iron at the pouring gate, this method is very inaccurate and cannot monitor the specific position of the molten iron inside the mold cavity in real time. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the prior art by providing a device for monitoring and early warning of the position of molten iron in a casting cavity.

[0005] To achieve the above objectives, the utility model adopts the following technical solution: a casting cavity molten iron position monitoring and early warning device, comprising a mobile vehicle, a mounting frame on the mobile vehicle, a control box mounted on the mounting frame, a fixed box mounted on the mounting frame, a winding assembly electrically connected to the control box inside the fixed box, a first connecting wire and a second connecting wire wound on the winding assembly, a drive assembly for rotating the winding assembly inside the fixed box, a wire management assembly for cooperating with the first connecting wire and the second connecting wire inside the fixed box, and an alarm light and a speaker on the control box.

[0006] By adopting the above technical solution, the molten iron position monitoring and early warning device for the casting cavity, through the installation of a mounting frame, control box, fixed box and winding assembly on the mobile vehicle, realizes effective monitoring and early warning of the molten iron position in the cavity. By extending the first connecting line and the second connecting line to the designated position in the cavity, when the molten iron overflows to the designated position, the first connecting line and the second connecting line form a path through the molten iron and transmit the path signal to the control box. After receiving the message, the control box controls the alarm and speaker to perform alarm processing.

[0007] Optionally, the fixing box includes a box body and an end cap disposed on the box body, wherein the box body has wire holes for the first connecting wire and the second connecting wire to pass through.

[0008] By adopting the above technical solution and the design of the end cap, the fixed box can be opened easily for maintenance of the equipment inside the fixed box, while the design of the wire hole allows the first and second connecting wires to extend into the cavity through the wire hole.

[0009] Optionally, the housing and the end cap are respectively provided with mutually mating support seats, and the support seats are provided with arc-shaped grooves for mounting the winding assembly.

[0010] By adopting the above technical solution, the housing and end cover of the fixed box achieve stable installation and positioning of the winding assembly through the cooperation of the support base and the arc groove. This structure not only improves the stability of the winding assembly, but also allows for convenient disassembly and assembly of the winding assembly during maintenance.

[0011] Optionally, the winding assembly includes a drum and baffles disposed at the ends and middle of the drum. A rotating shaft is mounted on the surface of the end baffles, and a wire rotary connector is mounted on the other end of the rotating shaft. A wire connected to the control box is mounted on the other end of the wire rotary connector.

[0012] By adopting the above technical solution, the combined design of the winding assembly's drum, baffle, shaft, wire rotary joint, and conductor enables the orderly winding and flexible extension of the first and second connecting lines. The structure of the drum and baffle effectively prevents the lines from becoming loose or tangled during winding, ensuring the neatness of the lines. The setting of the wire rotary joint allows the conductor to stably transmit signals when the winding assembly rotates, avoiding signal interruption or damage caused by line twisting, ensuring the continuity and stability of signal transmission, and thus improving the accuracy and reliability of the device in monitoring the position of molten iron.

[0013] Optionally, the drive assembly includes a drive motor installed in the fixed box, a drive gear is installed at the output end of the drive motor, and a driven gear meshing with the drive gear is provided on the winding assembly.

[0014] By adopting the above technical solution, the cooperation of the drive motor, the active gear and the driven gear in the drive assembly provides a stable power source for the winding assembly. The drive motor can accurately control the rotation speed and direction of the winding assembly, and the meshing transmission of the active gear and the driven gear ensures efficient power transmission, so that the first connecting line and the second connecting line can be accurately extended or wound up as needed. This design not only improves the automation level of the device and reduces the tediousness of manual operation, but also allows for flexible adjustment of the extension length of the line, enhancing the adaptability and flexibility of the device.

[0015] Optionally, the cable management assembly includes a forward and reverse threaded rod connected to the fixed box. The forward and reverse threaded rods are provided with a pair of thread seats, and the pair of thread seats are respectively provided with cable management seats for the first connecting wire and the second connecting wire to pass through. The reverse threaded rod is provided with a connecting gear that meshes with the driven gear.

[0016] By adopting the above technical solution, the combination of the positive and negative threaded rods, thread seats, and thread management seats of the wire management assembly achieves effective organization and guidance of the first and second connecting wires. The bidirectional thread design of the positive and negative threaded rods can simultaneously drive a pair of thread seats to move relative to or in opposite directions, thereby realizing synchronous wire management operations for the two lines. The setting of the thread management seats provides stable support and guidance for the lines, avoiding phenomena such as crossing and tangling during the extension or rewinding of the lines, ensuring the smooth passage of the lines. This design of the wire management assembly greatly improves the management efficiency of the lines, reduces the risk of line failure, extends the service life of the lines, and also improves the overall operating efficiency and stability of the device, providing a strong guarantee for the accurate monitoring of the position of molten iron in the casting cavity.

[0017] Optionally, the alarm light and speaker are electrically connected to the control box, and the control box is provided with a heat dissipation window.

[0018] By adopting the above technical solution, the alarm light and speaker are electrically connected to the control box, enabling timely and accurate alarms for abnormal molten iron positions. When the molten iron fills to the designated position, the control box can quickly receive the signal and control the alarm light to flash and the speaker to sound an alarm, reminding the operator to take timely measures to avoid defects in the casting or safety accidents.

[0019] Optionally, the mounting bracket includes support columns and connecting columns installed between the support columns, the support columns having grooves for mounting the control box.

[0020] By adopting the above technical solution, the support column and connecting column structure of the mounting frame, as well as the groove set on the support column, provide a stable mounting platform for components such as control box and fixed box. The structural design of the support column can withstand a certain weight and external force, ensuring the stability of each component during operation and avoiding loosening or damage to the components due to vibration or external force.

[0021] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up a mounting frame, control box, fixing box and wire winding assembly on the mobile vehicle, the first connecting line and the second connecting line are extended to the designated position in the mold cavity. When molten iron overflows to the designated position, the two lines form a passage. After the signal is transmitted to the control box, the alarm and speaker alarm are triggered. This realizes effective monitoring and early warning of the position of molten iron in the mold cavity and solves the problem of difficult monitoring of molten iron position in traditional casting process.

[0022] 2. The drive motor, drive gear, and driven gear in the drive assembly work together to provide stable power to the winding assembly, precisely control the rotation speed and direction, ensure efficient power transmission, and enable the wire to extend or rewind accurately. This improves the automation level of the device, reduces manual operation, and enhances adaptability and flexibility.

[0023] 3. The combination of the positive and negative threaded rods, thread holders, and cable management seats of the cable management assembly enables effective organization and guidance of the first and second connecting wires, avoiding wire crossing and tangling, ensuring smooth wire passage, improving line management efficiency, reducing the risk of failure, extending the service life of the lines, and ensuring stable operation of the device.

[0024] 4.

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, they should not be construed as limitations on this utility model.

[0029] like Figure 1 As shown in Figure 3, the specific solution of the embodiment is as follows: A casting cavity molten iron position monitoring and early warning device includes a mobile carriage 1. The mobile carriage 1 includes a base plate and pulleys set on the lower surface of the base plate. The pulleys drive a self-locking device. A push rod is installed on the upper surface of the mobile carriage 1. The design of the mobile carriage 1 makes it convenient to move the device flexibly to different positions in the casting workshop, which is convenient for monitoring the molten iron position of casting cavities at different positions. At the same time, the self-locking device on the pulleys can fix the mobile carriage 1 after the device reaches the designated position, preventing it from moving during operation and ensuring the stability of monitoring. The mobile vehicle 1 is equipped with a mounting frame 2, which includes support columns 21 and connecting columns 22 installed between the support columns 21. The support columns 21 are provided with grooves 23 for mounting the control box 3. The structural design of the support columns 21 and connecting columns 22, as well as the grooves 23 on the support columns 21, enables the control box 3 and the fixed box 4 to be firmly installed on the mobile vehicle 1, ensuring the stability of each component during operation. This structural design also facilitates the installation and disassembly of components, making the assembly and maintenance of the device easier.

[0030] The mounting bracket 2 is equipped with a control box 3, which has an alarm light 10 and a speaker 11. The alarm light 10 and speaker 11 are electrically connected to the control box 3. The control box 3 has a heat dissipation window 31. The control box 3 contains a control unit that is responsible for receiving incoming signals and controlling the alarm light 10 and speaker 11 to sound an alarm based on the signals, so as to remind the operator that the molten iron position is abnormal.

[0031] The mounting bracket 2 is equipped with a fixed box 4, which includes a box body 41 and an end cap 42 on the box body 41. The box body 41 has a wire hole 43 for the first connecting wire 6 and the second connecting wire 7 to pass through. The box body 41 and the end cap 42 are respectively provided with mutually mating support seats 44. The support seats 44 have an arc-shaped groove 45 for the installation of the winding assembly 5. The fixed box is used to install the winding assembly 5, the drive assembly 8 and the cable management assembly 9, providing a closed protective space for these components to prevent dust, impurities and other damage to the components. The structural design of the box body 41 and the end cap 42, as well as the cooperation of the support seats 44 and the arc-shaped groove 45, realize the stable installation and positioning of the winding assembly 5. This structure not only improves the stability of the winding assembly 5, enabling it to maintain good rotation performance during operation and avoiding problems such as wire entanglement caused by shaking or displacement, but also facilitates the installation and disassembly of the winding assembly 5, making subsequent maintenance and repair work more convenient.

[0032] The fixed box 4 contains a cable winding assembly 5 electrically connected to the control box 3. The cable winding assembly 5 includes a drum 51 and baffles 52 disposed at the ends and middle of the drum 51. A rotating shaft 53 is mounted on the surface of the end baffles 52. A wire rotary connector 54 is mounted on the other end of each rotating shaft 53. A wire 55 connected to the control box 3 is mounted on the other end of each wire rotary connector 54. The cable winding assembly 5 is used to wind and unwind the first connecting wire 6 and the second connecting wire 7, ensuring that the wires can flexibly extend to the designated position in the casting cavity. (Drum 51, baffles 52, etc.) The combined design of the rotating shaft 53, the wire rotary joint 54, and the wire 55 enables the orderly winding and flexible extension of the first connecting wire 6 and the second connecting wire 7. The structure of the drum 51 and the baffle 52 can effectively prevent the wire from becoming loose or messy during the winding process, ensuring the neatness of the wire. The setting of the wire rotary joint 54 allows the wire 55 to stably transmit signals when the winding assembly 5 rotates, avoiding signal interruption or damage caused by wire twisting, ensuring the continuity and stability of signal transmission, and thus improving the accuracy and reliability of the device in monitoring the position of molten iron.

[0033] The winding assembly 5 has a first connecting wire 6 and a second connecting wire 7 wound on it. The fixed box 4 is equipped with a drive assembly 8 for rotating the winding assembly 5. The drive assembly 8 includes a drive motor 81 installed in the fixed box 4. The output end of the drive motor 81 is equipped with a drive gear 82. The winding assembly 5 is equipped with a driven gear 83 that meshes with the drive gear 82. The cooperation of the drive motor 81, the drive gear 82 and the driven gear 83 provides a stable power source for the winding assembly 5. The drive motor 81 can control the rotation speed and direction of the winding assembly 5. The meshing transmission of the drive gear 82 and the driven gear 83 ensures efficient power transmission, so that the first connecting wire 6 and the second connecting wire 7 can be accurately extended or wound as needed. This design not only improves the automation level of the device and reduces the tediousness of manual operation, but also flexibly adjusts the extension length of the line, enhances the adaptability and flexibility of the device, and further improves the quality and efficiency of casting production.

[0034] The fixed box 4 is equipped with a cable management assembly 9 that works with the first connecting wire 6 and the second connecting wire 7. The cable management assembly 9 includes a forward and reverse threaded rod 91 connected to the fixed box 4. The forward and reverse threaded rod 91 is equipped with a pair of thread seats 92. The pair of thread seats 92 are respectively equipped with cable management seats 93 for the first connecting wire 6 and the second connecting wire 7 to pass through. The reverse threaded rod 91 is equipped with a connecting gear 94 that meshes with the driven gear 83. The combination of the forward and reverse threaded rod 91, the thread seats 92, and the cable management seats 93 effectively organizes and guides the first connecting wire 6 and the second connecting wire 7. Under the rotation of the driven gear 83, the meshing connecting gear is driven synchronously. 94. The connecting gear 94 drives the positive and negative threaded rods 91. The bidirectional thread design of the positive and negative threaded rods 91 can simultaneously drive a pair of thread seats 92 to move relative to or in opposite directions, thereby realizing the synchronous thread management operation of the two lines. The setting of the thread management seat 93 provides stable support and guidance for the lines, avoiding phenomena such as crossing and tangling during the extension or rewinding of the lines, ensuring the smooth passage of the lines. This design of the thread management component 9 greatly improves the management efficiency of the lines, reduces the risk of line failure, extends the service life of the lines, and also improves the overall operating efficiency and stability of the device, providing a strong guarantee for the accurate monitoring of the position of molten iron in the casting cavity.

[0035] The monitoring steps in the above embodiments are as follows: As needed to monitor the position of the casting cavity, push the moving cart 1 to move it to the appropriate position. After reaching the designated position, operate the self-locking device to fix the moving cart 1 and prevent it from moving during the operation. The drive motor 81 in the drive assembly 8 is started. The drive motor 81 drives the winding assembly 5 to rotate through the meshing of the drive gear 82 and the driven gear 83. This causes the first connecting wire 6 and the second connecting wire 7 wound on the winding assembly 5 to extend out of the fixed box 4. During the extension process, the driven gear 83 drives the connecting gear 94. The connecting gear 94 drives the positive and negative threaded screws 91 of the wire management assembly 9 to rotate, causing a pair of thread seats 92 to move relative to each other or towards each other. The wire management seat 93 on the thread seat 92 guides the first connecting wire 6 and the second connecting wire 7 to ensure that the wires extend smoothly to the designated position in the casting cavity. Install the extended first connecting line 6 and the second connecting line 7 at the designated positions in the casting cavity; When the ends of the first connecting line 6 and the second connecting line 7 come into contact with the molten iron and form a circuit, the signal will be transmitted to the control unit in the control box 3 through the wire 55. After receiving the signal, the control unit will perform a quick analysis and judgment to confirm that the position of the molten iron has reached the set warning threshold. At this time, the control unit will immediately trigger the alarm light 10 and the speaker 11. The alarm light 10 will flash at a high frequency and emit a bright red light. At the same time, the speaker 11 will emit a high-decibel alarm sound to remind the operator that the molten iron is about to be filled.

[0036] Once the monitoring is complete, start the drive assembly 8 and retract the first connecting cable 6 and the second connecting cable 7 into the fixed box 4 for future use.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
