Description

Technical Field

[0001] The utility model relates to the technical field of overturning devices, and in particular to a molding box overturning device with a balance adjustment function. Background Art

[0002] In the foundry industry, flipping the molding box faces many difficulties. First, manual flipping requires a lot of time and physical strength of workers. Workers must rely on their own strength and use simple tools such as crowbars to complete the flipping operation, which is extremely cumbersome and inefficient. Secondly, due to the complete reliance on manpower and experience, there are differences in the operating levels of different workers, resulting in uneven flipping results, which increases the uncertainty in the production process. However, when the molding box is flipped using equipment, it will sink. The material distribution in the molding box is often uneven, and it is likely that the material will sink. Once this happens, the center of gravity of the molding box will shift during the flipping process. The shift in the center of gravity will make flipping extremely difficult, and will also cause additional torque and impact forces on the molding box. These abnormal forces will act on the flipping equipment, which may cause equipment failure or damage. Utility Model Content

[0041] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0042] Referring to Figures 1 to 5 , which is the first embodiment of the present invention, a molding box flipping device with a balance adjustment function is proposed. It is connected to a crane and used to flip the molding box, including a first mounting bracket 1; both ends of the mounting rod 2 are rotatably arranged on the first mounting bracket 1; one end of the suspension ring 3 is relatively slidably arranged on the mounting rod 2, and the other end is hinged to the crane; the inclination sensor 4 is arranged on the first mounting bracket 1 and is used to detect whether the first mounting bracket 1 is tilted.

[0043] In this embodiment, the first mounting bracket 1 is welded from high-strength steel and is in the overall shape of a rectangular frame structure. The four corners of the frame are reinforced by reinforcing ribs to ensure that it can withstand large weights and external forces. At both ends of the frame, there are dedicated mounting seats for mounting the rotating mounting rod 2. Both ends of the mounting rod are connected to the mounting seats of the first mounting bracket 1 through precision ball bearings. The lifting ring 3 is made of high-strength alloy steel, and one end is slidably mounted on the mounting rod 2. The other end of the lifting ring 3 is connected to the hook of the overhead crane through a hinge. The inclination sensor 4 is a high-precision electronic inclination sensor, which is fixed at the center position of the first mounting bracket 1 by bolts. The sensor is connected to the control system and can transmit the inclination angle data of the first mounting bracket 1 to the control system in real time for timely adjustment.

[0044] The stable structural design of the first mounting bracket 1 ensures the stability and reliability of the entire flipping device during operation, can adapt to various complex working environments, and reduces shaking or deformation caused by external interference or its own structural problems. The sliding connection design between the lifting ring 3 and the mounting rod 2 enables the lifting ring 3 to quickly adjust its position when abnormal situations such as tilting occur in the device, rebalance the center of gravity of the device, effectively avoid safety accidents caused by the shift of the center of gravity, and improve the safety of the device. The real-time monitoring function of the inclination sensor 4 can timely detect the inclination of the first mounting bracket 1, provide accurate data support for the automatic adjustment of the device, enable the device to respond immediately, avoid the further expansion of the inclination angle, reduce potential safety risks, and ensure the safe and stable operation of the flipping operation.

[0045] Furthermore, the mounting rod 2 is threadedly connected to one end of the lifting ring 3, and further includes a first driving member 5. The first driving member 5 is arranged on the first mounting bracket 1, and the output end of the first driving member 5 is drivingly connected to one end of the mounting rod 2 for driving the mounting rod 2 to rotate.

[0046] In this embodiment, the surface of the mounting rod 2 is provided with external threads, and one end of the mounting rod 2 extends to the outside of the first mounting bracket 1 and is connected to the first driving member 5. The first driving member 5 is a high-precision servo motor, and the motor is connected to the mounting rod 2 through a coupling. The coupling can effectively transmit the torque of the motor, reduce energy loss and transmission error. The servo motor has precise speed and torque control functions and can accurately drive the mounting rod 2 to rotate according to the instructions of the control system. When it is necessary to adjust the position of the lifting ring 3, the control system sends an instruction to the servo motor, and the servo motor starts to rotate, driving the mounting rod 2 to rotate. Since the lifting ring 3 and the mounting rod 2 are threadedly connected, the rotation of the mounting rod 2 will cause the lifting ring 3 to move axially along the threads of the mounting rod 2.

[0047] The advantage is that the threaded connection design on the mounting rod 2 enables the movement of the lifting ring 3 on the mounting rod 2 to be precise and controllable. Through the rotational drive of the thread, fine adjustment of the position of the lifting ring 3 can be achieved, meeting the precise requirements for the position of the lifting ring 3 under different working conditions. The combination of the threaded connection and the servo motor drive makes the entire device more flexible and reliable when adjusting the position of the lifting ring 3.

[0048] Furthermore, it further includes clamping arms 6. There are two clamping arms 6. One ends of the two clamping arms 6 are both slidably arranged in the first mounting bracket 1. After the two clamping arms 6 slide, they approach or move away from each other; the first clamping jaw 7 is used in combination with the clamping arm 6. One end of the first clamping jaw 7 is rotatably arranged at the other end of the clamping arm 6. After the clamping arm 6 slides, the first clamping jaw 7 abuts against or disengages from the molding box.

[0049] Furthermore, the first clamping jaw 7 includes a rotating seat 701. One end of the rotating seat 701 is rotatably arranged at the end of the clamping arm 6 away from the first mounting bracket 1. The other end of the rotating seat 701 has a spherical head protrusion 7011; one end of the swinging member 702 has a spherical head groove 7021, which abuts against the spherical head protrusion 7011 to form a spherical hinge pair, and the other end abuts against the molding box.

[0050] In this embodiment, one end of the clamping arm 6 is slidably installed in the first mounting bracket 1. Ensure that the clamping arm 6 can slide smoothly and precisely in the first mounting bracket 1. The rotating seat 701 of the first clamping jaw 7 is made of a strong metal material. One end thereof is connected to the other end of the clamping arm 6 and can rotate at the other end of the clamping arm 6. A precision-machined spherical head protrusion 7011 is provided at the other end of the rotating seat 701. The swinging member 702 is made of a material with certain elasticity and wear resistance. One end thereof is provided with a spherical head groove 7021 that matches the spherical head protrusion 7011 of the rotating seat 701, and the two are in close contact to form a flexible spherical hinge pair. When the clamping arm 6 approaches the molding box, the swinging member 702 will automatically adjust its angle under the action of the spherical hinge pair according to the shape and angle of the surface of the molding box, so that the other end of the swinging member 702 can closely fit the surface of the molding box.

[0051] The advantage is that the design of the clamping arm 6 ensures the stability and reliability of the clamping arm 6 during the process of clamping and loosening the molding box, can withstand a large clamping force, and prevents the molding box from falling off during the flipping process. The design of the rotating seat 701 and the swinging member 702 of the first clamping jaw 7, especially the application of the spherical hinge pair, enables the first clamping jaw 7 to make adaptive adjustments according to the actual shape of the molding box, greatly improving the adaptability and tightness of clamping, being able to effectively clamp molding boxes of different shapes and sizes, and reducing the safety hazards caused by uneven or loose clamping force. This design can ensure that during the process of flipping the molding box, the clamping device always remains in close contact with the molding box, improving the stability and safety of the flipping operation and reducing the probability of accidental accidents caused by poor clamping.

[0052] Further, it further includes protective jaws 8. The protective jaws 8 are used in pairs. One end of each of the two protective jaws 8 is slidably arranged on both sides of the rotating seat 701, and the sliding direction is perpendicular to the sliding direction of the two clamping arms 6. After the two protective jaws 8 slide, the protective jaws 8 abut or are in contact with the molding box.

[0053] In this embodiment, the protective jaws 8 are installed on both sides of the rotating seat 701 through a guide rail. The guide rail has the characteristics of high guiding accuracy and strong bearing capacity, and can ensure the stability and accuracy of the protective jaws 8 during the sliding process. When it is necessary to clamp or protect the molding box more firmly, the control system issues an instruction, and the electric push rod starts to work, pushing the protective jaws 8 to slide along the guide rail towards the molding box, and tightly abutting against the side surface of the molding box. The surface of the protective jaws 8 is provided with a rubber anti-slip pad to increase the friction with the molding box and prevent the molding box from sliding.

[0054] The advantage is that the protective jaws 8 can be used for a long time in a harsh working environment. The use of the guide rail makes the sliding of the protective jaws 8 more accurate and reliable, and can adjust the clamping force in a timely manner according to needs. The setting of the protective jaws 8 increases the clamping points and clamping force on the molding box, improves the stability and reliability of clamping, and can effectively prevent the molding box from accidentally slipping or shifting during the flipping process, ensuring the safety of the operator.

[0055] Further, it further includes a counterweight 9, and the counterweight 9 is arranged at one end of the first mounting bracket 1.

[0056] In this embodiment, the counterweight 9 is made of cast iron and is in the shape of a cuboid. A special counterweight mounting groove is provided at one end of the first mounting bracket 1, and the counterweight 9 is fixed in the counterweight mounting groove by bolts. According to the center of gravity and balance requirements of the flipping device, counterweights 9 with different weights and quantities can be selected for combined installation.

[0057] The advantage is that the counterweight 9 made of cast iron has the characteristics of high density and good stability, and can effectively adjust the center of gravity of the flipping device, making the device more stable during the flipping process. By accurately calculating and reasonably selecting the weight and quantity of the counterweight 9, the balance performance of the flipping device can be optimized, the load requirements on the overhead crane and other components can be reduced, the service life of the equipment can be extended, and at the same time, the safety and reliability of operation can be improved.

[0058] Further, it further includes a sliding block 10. One end of the sliding block 10 is slidably arranged on the upper surface of the first mounting bracket 1, and the other end is connected to the end of the lifting ring 3 away from the overhead crane.

[0059] In this embodiment, one end of the sliding block 10 is mounted on the guide rail on the upper surface of the first mounting bracket 1 through a slider. The cooperation between the dovetail slider and the dovetail guide rail has the characteristics of high precision and high load-bearing capacity, which can ensure the smooth sliding of the sliding block 10 on the upper surface of the first mounting bracket 1. The other end of the sliding block 10 is connected to the lower end of the lifting ring 3 through a high-strength pin shaft. When an external force is applied to the lifting ring 3 or its position changes, the sliding block 10 slides correspondingly on the dovetail guide rail to adapt to the movement of the lifting ring 3. During the sliding process, the friction between the sliding block 10 and the guide rail is small, which can reduce energy loss and wear. At the same time, in order to prevent the sliding block 10 from disengaging from the guide rail during the sliding process, limit devices are provided at both ends of the guide rail.

[0060] The advantages are that the sliding block 10 has good wear resistance and strength, and can maintain stable performance during long-term use. The application of the dovetail slider and the dovetail guide rail makes the sliding of the sliding block 10 more accurate and reliable, and can adapt to different force conditions and flipping angles. The setting of the sliding block 10 increases the connection flexibility between the lifting ring 3 and the first mounting bracket 1, reduces the stress concentration caused by uneven force or position change of the lifting ring 3, and extends the service life of the lifting ring 3 and the first mounting bracket 1.

[0061] Furthermore, it further includes two gears 11 which are rotatably arranged in the first mounting bracket 1; a rack 12 is slidably arranged in the first mounting bracket 1, and the rack 12 is in meshing transmission with the gears 11, and one end of the clamping arm 6 located in the first mounting bracket 1 is arranged at one end of the rack 12.

[0062] In this embodiment, the gears 11 are installed in the first mounting bracket 1 through a strong transmission shaft and bearings. The tooth profile of the gears 11 is precision machined to ensure the meshing accuracy with the rack 12. The surface of the rack 12 is quenched to improve hardness and wear resistance. The rack 12 is installed in the first mounting bracket 1 through a linear guide rail, and the linear guide rail ensures the sliding direction and accuracy of the rack 12. One end of the clamping arm 6 located in the first mounting bracket 1 is connected to one end of the rack 12 through a rigid connecting piece. When the gears 11 rotate, through the meshing transmission with the rack 12, the rack 12 is driven to slide on the linear guide rail, so that the clamping arm 6 slides in the first mounting bracket 1. On one side of the gears 11, a driving motor is provided, and the driving motor is connected to the transmission shaft of the gears 11 through a coupling to provide power for the rotation of the gears 11.

[0063] The advantages are that the gears 11 and the rack 12 made of high-quality alloy steel have high strength and high wear resistance, and can withstand large loads and frequent transmissions. The gear-rack transmission mechanism has the advantages of high transmission accuracy and strong load-bearing capacity, can accurately control the sliding position of the clamping arm 6, and ensure the accuracy and reliability of the clamping force.

[0064] Furthermore, the end of the swing member 702 that abuts against the molding box has anti-slip patterns.

[0065] In this embodiment, at the end of the swing member 702 that abuts against the molding box, grid-shaped anti-slip patterns are processed by laser engraving technology. The depth and spacing of the anti-slip patterns can ensure sufficient friction while not causing excessive damage to the surface of the molding box. The surface of the anti-slip patterns has also undergone special treatment to increase its wear resistance and corrosion resistance, ensuring that it will not wear or fall off during long-term use.

[0066] The advantage is that the grid-shaped anti-slip patterns increase the contact area with the surface of the molding box, improve the friction, and make the clamping more stable and reliable.
