DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0020] The present application provides a steel transfer machine, the structure of which is as follows: Figure 1- Figure 6 As shown, it includes a main body mechanism 1, a lifting mechanism 2 and a driving mechanism 3.

[0021] The main mechanism 1 includes two guide rails 12, the two guide rails 12 are parallel, a frame 11 is slidably connected between the two guide rails 12, the frame 11 slides along the length direction of the guide rails 12, two motors 13 are arranged on the frame 11, the motors 13 are motors with encoders, a reducer 14 is arranged between the two motors 13 on the frame 11, the output shafts of the two motors 13 are connected to the input end of the reducer 14, and the output end of the reducer 14 is provided with two rotating shafts 1 5, a gear 16 is provided at the end of the rotating shaft 15, a rack 17 meshing with the gear 16 is provided on the guide rail 12, the rack 17 extends along the length direction of the guide rail 12, a limiting wheel 18 is provided at the end of the rotating shaft 15, a limiting strip 19 matched with the limiting wheel 18 is provided on the guide rail 12, a drag chain 6 for winding up the electric wire is also provided on the guide rail 12, a bridge frame 61 for supporting the drag chain 6 is provided on the guide rail 12, and a guide wheel 62 for limiting the drag chain 6 is rotatably connected to the bridge frame 61.

[0022] The lifting mechanism 2 includes four brackets 21, a rotating rod 22 and a plurality of pulling grips 23. The four brackets 21 are respectively arranged on both sides of the frame 11, the rotating rod 22 is rotatably connected between two brackets 21, and the plurality of pulling grips 23 are sequentially arranged on the rotating rod 22 at intervals along the length direction of the rotating rod 22.

[0023] The driving mechanism 3 includes an electro-hydraulic push rod 31 disposed on one side of the frame 11, the electro-hydraulic push rod 31 is located between the two brackets 21, and the piston rod of the electro-hydraulic push rod 31 is hinged to the middle of the rotating rod 22. The stroke of the electro-hydraulic push rod 31 is 250mm, the thrust and pull of the electro-hydraulic push rod 31 are 20000N, and the retraction time of the puller 23 is 2.78s.

[0024] When in use, when not started, the frame 11 is located at a certain position on the guide rail 12, the motor 13, the reducer 14 and other components are in a stationary state, the drag chain 6 is placed on the bridge 61, and the guide wheel and the drag chain 6 are in a relatively stable state. When the frame 11 needs to be moved, the motor 13 is started. Since the motor 13 is a motor 13 with an encoder, the speed and rotation angle of the motor 13 can be accurately controlled. It should be noted that one of the motors 13 is a spare motor 13. The output shaft of the motor 13 rotates, and the power is transmitted to the reducer 14. The reducer 14 reduces the high speed of the motor 13 to obtain a suitable output speed and a large torque, so that the shaft 15 can drive the gear 16 to rotate at an appropriate speed and sufficient force. The shaft 15 at the output end of the reducer 14 rotates, driving the gear 16 at the end to rotate. The gear 16 meshes with the rack 17 on the guide rail 12. Since the rack 17 is fixed on the guide rail 12 and extends along the length direction of the guide rail 12, when the gear 16 rotates, according to the transmission principle of the gear 16 and the rack 17, the frame 11 will slide along the length direction of the guide rail 12. By controlling the forward and reverse rotation of the motor 13, the two-way movement of the frame 11 on the guide rail 12 can be achieved. The limit wheel 18 at the end of the rotating shaft 15 rolls along the limit bar 19 on the guide rail 12 during the movement of the frame 11. The limit bar 19 guides and limits the limit wheel 18 to ensure that the frame 11 maintains a stable direction during the movement and prevents the frame 11 from deflecting or shaking. As the frame 11 moves, the wires connected to the frame 11 need to move accordingly to ensure the normal power supply and signal transmission of the motor 13 and other equipment. The drag chain 6 is used to reel in the wires to prevent the wires from being scattered and damaged. When the frame 11 moves, the drag chain 6 slides on the bridge 61. The bridge 61 supports the drag chain 6 so that the drag chain 6 can move smoothly. The guide wheel is rotatably connected to the bridge 61 to limit the drag chain 6, prevent the drag chain 6 from being separated from the bridge 61 or being excessively bent, and ensure that the wires in the drag chain 6 are safe and reliable.

[0025] Two brackets 21 are fixed on one side of the frame 11 to provide support for the rotating rod 22. The rotating rod 22 is rotatably connected between the two brackets 21 and can rotate around its own axis. The pulling grip 23 is used to grab and lift the steel. The electro-hydraulic push rod 31 is set on one side of the frame 11, located between the two brackets 21. The piston rod of the electro-hydraulic push rod 31 is hinged to the middle of the rotating rod 22. When the piston rod of the electro-hydraulic push rod 31 is extended, it pushes the rotating rod 22 to rotate around the bracket 21, so that the pulling grip 23 lifts the steel upward. When the piston rod is retracted, the rotating rod 22 rotates in the opposite direction, and the pulling grip 23 puts down the steel. When it is necessary to move the steel, the electro-hydraulic push rod 31 is started, the piston rod is extended, and the rotating rod 22 is pushed to rotate around the bracket 21. The pulling grip 23 on the rotating rod 22 is lifted upward as the rotating rod 22 rotates, grabbing the steel. Then, the electro-hydraulic push rod 31 continues to push the rotating rod 22, so that the steel is lifted to a certain height. Then, the steel is moved to the desired position by other equipment or mechanisms. When the destination is reached, the piston rod of the electrohydraulic push rod 31 is retracted, the rotating rod 22 rotates in the opposite direction, and the steel is put down by the puller 23 to complete the steel moving operation.

[0026] In addition, it should be noted that due to the on-site production process layout, different process requirements need to be met, such as: the billet is straightened, flame cut, and conveyed to the steel transfer machine through the continuous casting process. Due to the production process requirements, the billet on one side of the steel transfer machine is required to be conveyed to the conveyor roller in the direction of the steel rolling process, and the billet on one side needs to be conveyed to the lifting roller to the cooling bed process, and the process requirements such as hoisting and vehicle transfer of billets are adopted. Since the four brackets 21 in the present application are respectively arranged on both sides of the frame 11, the present application can be applied to various complex on-site layouts.

[0027] In the present application, the frame 11 of the main mechanism 1 and the bracket 21 of the lifting mechanism 2 provide stable support for the steel moving machine, ensuring that there will be no shaking or tilting during the steel moving process. The electro-hydraulic push rod 31 of the driving mechanism 3 has high thrust and stability, and acts on the middle part of the rotating rod 22, and can reliably push the rotating rod 22 and the pulling grip 23 to work. At the same time, the main function of the multiple pulling grips 23 is to smoothly move the steel billet to the next process, one side to the hot delivery roller, the other side to the lifting roller, and on the upper cooling bed, thereby improving the safety and reliability of steel moving and improving the production quality.

[0028] In order to make the rotating rod 22 rotate smoothly and stably, please refer to Figure 6In a preferred embodiment, the rotating rod 22 is rotatably connected between the two brackets 21 through a bearing 43 assembly 4, and the bearing 43 assembly 4 includes a bearing 43 seat 41 arranged on the bracket 21, and a through hole 42 is provided on the bearing 43 seat 41, and a bearing 43 is arranged in the through hole 42, and a distance ring 44 is provided at both ends of the bearing 43 in the through hole 42, and one side of the distance ring 44 is used to abut against the end surface of the bearing 43, and the other side of the distance ring 44 is used to abut against the bearing 43 seat 41.

[0029] During use, when the steel transfer machine starts working and the rotating rod 22 needs to rotate, the bearing 43 plays the role of supporting the rotating rod 22 and making it rotate smoothly. The inner ring 432 of the bearing 43 is tightly matched with the rotating rod 22, and the outer ring 431 is matched with the bearing 43 seat 41. The rotation of the rotating rod 22 drives the inner ring 432 of the bearing 43 to rotate, while the outer ring 431 is relatively statically fixed on the bearing 43 seat 41. The setting of the distance ring 44 is mainly to ensure that the position of the bearing 43 in the through hole 42 is accurate. One side of the distance ring 44 abuts against the end face of the bearing 43 to prevent the bearing 43 from moving in the axial direction and ensure the stability of the bearing 43 during operation. In addition, the existence of the distance ring 44 can make the two ends of the bearing 43 bear force evenly, preventing the bearing 43 from being deflected or damaged due to uneven force during operation.

[0030] To improve the sealing performance of the bearing 43 seat 41, please refer to Figure 6 In a preferred embodiment, a cover 45 is provided on the end of the bearing 43 seat 41 away from the rotating rod 22, and the cover 45 is used to seal the bearing 43. A transparent cover 46 is provided on the end of the bearing 43 seat 41 close to the rotating rod 22, and a through hole 47 is provided on the transparent cover 46 for the rotating rod 22 to pass through.

[0031] When in use, the cover 45 is installed at the end of the bearing 43 seat 41 away from the rotating rod 22 to seal the bearing 43. Its main function is to prevent external dust, impurities, moisture, etc. from entering the bearing 43 seat 41, and protect the bearing 43 from being polluted and eroded by the external environment. In this way, the service life of the bearing 43 can be extended, and the bearing 43 can be ensured to operate in a good working environment. The cover 45 can maintain the pressure inside the bearing 43 seat 41 to a certain extent. When the rotating rod 22 rotates, a certain amount of friction heat will be generated inside the bearing 43. The cover 45 can reduce the exchange of internal air with the outside world, thereby helping to stabilize the temperature and pressure inside the bearing 43 seat 41 and avoid adverse effects on the working performance of the bearing 43 due to temperature and pressure changes. The transparent cover 46 is installed at the end of the bearing 43 seat 41 close to the rotating rod 22, and the transparent cover 46 is provided with a transparent hole 47 for the rotating rod 22 to pass through. The transparent cover 46 can prevent the rotating rod 22 from colliding or rubbing with external objects during the rotation process, and play a certain protective role for the rotating rod 22. At the same time, the transparent cover 46 can also perform axial positioning on the rotating rod 22 to ensure that the rotating rod 22 does not undergo axial displacement during the rotation process, thereby ensuring the rotation accuracy and stability of the rotating rod 22 .

[0032] To improve the stability of bearing 43 during rotation, please refer to Figure 7 In a preferred embodiment, baffles 48 are provided at both ends of the bearing 43 seat 41 on the bracket 21 , and the baffles 48 are used to abut against the ends of the bearing 43 seat 41 .

[0033] During use, when the steel moving machine starts working and the rotating rod 22 rotates, certain vibrations and axial forces will be generated. The function of the baffle 48 is to limit the axial movement of the bearing 43 seat 41 on the bracket 21, ensuring that the bearing 43 seat 41 always remains in the correct position. The baffle 48 abuts against the end of the bearing 43 seat 41 to prevent the bearing 43 seat 41 from being displaced under the action of the axial force, thereby ensuring the axial position of the rotating rod 22 is stable. In addition, the presence of the baffle 48 can increase the connection strength between the bracket 21 and the bearing 43 seat 41, and improve the stability of the entire steel moving machine structure. During the rotation of the rotating rod 22 and the steel moving operation, the baffle 48 can share part of the weight and force from the rotating rod 22 and the steel, reduce the direct pressure on the bearing 43 seat 41 and the bracket 21, and reduce the risk of structural damage.

[0034] In order to further improve the stability of the rotating rod 22 during rotation, please refer to Figure 8 In a preferred embodiment, the bearing 43 includes an outer ring 431 and an inner ring 432 rotatably connected to the outer ring 431, and a retaining ring 433 is provided between the outer ring 431 and the inner ring 432, one side of the retaining ring 433 abuts against the outer ring 431, and the other side of the retaining ring 433 abuts against the inner ring 432.

[0035] When in use, when the rotating rod 22 rotates, the inner ring 432 rotates with the rotating rod 22, and the outer ring 431 is relatively stationary. The function of the retaining ring 433 is to limit the relative displacement of the inner ring 432 and the outer ring 431 in the axial direction, ensuring that the inner ring 432 and the outer ring 431 always maintain the correct relative position. In addition, the retaining ring 433 can prevent the inner ring 432 from excessively moving to one side of the outer ring 431 under the action of the axial force, thereby ensuring the normal working clearance of the bearing 43 and avoiding the wear of the bearing 43 being aggravated or damaged due to the position deviation of the inner ring 432 and the outer ring 431. Finally, the existence of the retaining ring 433 can make the inner ring 432 and the outer ring 431 more evenly stressed in the axial direction. When the rotating rod 22 is subjected to forces in different directions, the retaining ring 433 can evenly distribute these forces on the outer ring 431 and the inner ring 432, reduce local stress concentration, and improve the bearing capacity and working stability of the bearing 43.

[0036] To further improve the stability of the rotating rod 22, please refer to Figure 5 In a preferred embodiment, a bracket 24 is provided on the frame 11 , and the bracket 24 is located between the two brackets 21 . The bracket 24 is provided with a bracket 25 for accommodating the rotating rod 22 .

[0037] When in use, when the rotating rod 22 rotates between the brackets 21, the bracket 25 on the bracket 24 plays an auxiliary supporting role for the rotating rod 22. Since the rotating rod 22 will bear the weight of the steel and the torque and other forces during the steel transfer process, the bracket 24 can share part of the weight from the rotating rod 22, reducing the burden on the bracket 21 and the bearing 43. Especially when the rotating rod 22 is long or the weight of the steel to be transferred is large, the auxiliary support of the bracket 24 can effectively prevent the rotating rod 22 from bending and deforming due to uneven force, and ensure the straightness and rotation accuracy of the rotating rod 22. In addition, the bracket 24 can provide a certain buffering effect when the rotating rod 22 is accidentally impacted by external force, reducing direct damage to the rotating rod 22.

[0038] To reduce the possibility of damage to the rotating rod 22, please refer to Figure 5 In a preferred embodiment, a buffer plate 26 is provided on the rotating rod 22 , and a buffer 27 for receiving the buffer plate 26 is provided on the frame 11 .

[0039] When in use, the buffer 27 generates resistance to the movement of the buffer plate 26 by means of its own elastic deformation or hydraulic damping, thereby slowing down the movement speed of the rotating rod 22 and reducing the impact force of the rotating rod 22. This can prevent the rotating rod 22 from causing damage to other parts of the steel moving machine due to sudden stop or reverse movement, thereby improving the reliability and safety of the equipment. The combination of the buffer plate 26 and the buffer 27 can effectively protect the key parts of the steel moving machine, such as the electro-hydraulic push rod 31, the bracket 21, the bearing 43, etc. During the movement of the rotating rod 22, if there is no buffer device, the inertial force of the rotating rod 22 may have a greater impact on these parts, resulting in damage to the parts or shortening of their life.

[0040] To facilitate the installation, disassembly and replacement of the buffer 27, please refer to Fig. 9 In a preferred embodiment, the buffer 27 is connected to the frame 11 through a connecting assembly 5, and the connecting assembly 5 includes a connecting frame 51 arranged on the frame 11, and a connecting plate 53 is connected to the connecting frame 51 through a bolt 52. A screw 54 is provided on the buffer 27, and a through hole 55 is provided on the connecting plate 53 for the screw 54 to pass through. A nut 56 is threadedly connected to the screw 54, and the nut 56 abuts against a side of the connecting plate 53 away from the buffer 27.

[0041] When in use, the connecting frame 51 is firmly fixed on the frame 11, providing a stable foundation for the subsequent connection of the buffer 27. The connecting plate 53 is placed on the connecting frame 51, and the bolts 52 on the connecting frame 51 pass through the corresponding holes on the connecting plate 53. Then tighten the nuts 56 on the bolts 52 to fix the connecting plate 53 on the connecting frame 51. This ensures that the connecting plate 53 will not loosen or fall off during operation. The screw rod 54 on the buffer 27 passes through the through hole 55 on the connecting plate 53. The diameter of the screw rod 54 should match the size of the through hole 55 to ensure that the screw rod 54 can pass smoothly. After the screw rod 54 passes through the through hole 55, the nut 56 is screwed on the screw rod 54 and gradually tightened so that the nut 56 abuts against the side of the connecting plate 53 away from the buffer 27. The tightening force of the nut 56 fixes the buffer 27 on the connecting plate 53 to prevent the buffer 27 from being displaced during operation.

[0042] To facilitate the installation of nut 56 and improve the stability of nut 56, please refer to Fig. 9 In a preferred embodiment, a limit pin is provided on the screw rod 54 , and the limit pin abuts against a side of the nut 56 away from the connecting plate 53 .

[0043] During use, when installing the buffer 27, after screwing the nut 56 to the appropriate position, inserting the limit pin can quickly determine the position of the nut 56, which is convenient for the installer to install and adjust. At the same time, the limit pin can also be used as a reference point during the installation process to ensure the accuracy of the installation. During the operation of the steel moving machine, due to factors such as vibration and impact force, the nut 56 may tend to loosen. The setting of the limit pin can effectively prevent the loosening of the nut 56 and ensure that the connection between the buffer 27 and the connecting plate 53 is firm and reliable. Finally, the limit pin can share part of the pressure between the nut 56 and the screw 54, reducing the wear of the nut 56 and the screw 54. This helps to extend the service life of the connecting parts and reduce the maintenance cost of the equipment.

[0044] To reduce the possibility of damage to the electro-hydraulic push rod 31, please refer to Figure 5 In a preferred embodiment, a protective cover 32 is provided on the frame 11 around the electro-hydraulic push rod 31, and the top of the protective cover 32 is open.

[0045] When in use, on the one hand, the protective cover 32 surrounds the electro-hydraulic push rod 31, which can effectively prevent the operator from accidentally touching the running electro-hydraulic push rod 31 during work. The electro-hydraulic push rod 31 may generate high temperature, high pressure and fast-moving parts during operation. Once a person touches it by mistake, it may cause serious injury accidents. The existence of the protective cover 32 greatly reduces this risk. On the other hand, the top of the protective cover 32 is open, which is convenient for the staff to repair the electro-hydraulic push rod 31 and improves production efficiency.

[0046] In order to better understand this application, the following Figure 1 - Fig. 9 The working principle of a steel moving machine in the technical solution of the present application is described in detail: two brackets 21 are fixed on one side of the frame 11 to provide support for the rotating rod 22. The rotating rod 22 is rotatably connected between the two brackets 21 and can rotate around its own axis. The pulling grip 23 is used to grab and lift the steel. The electro-hydraulic push rod 31 is arranged on one side of the frame 11, between the two brackets 21. The piston rod of the electro-hydraulic push rod 31 is hinged to the middle part of the rotating rod 22. When the piston rod of the electro-hydraulic push rod 31 is extended, it pushes the rotating rod 22 to rotate around the bracket 21, so that the pulling grip 23 lifts the steel upward. When the piston rod retracts, the rotating rod 22 rotates in the opposite direction, and the pulling grip 23 puts down the steel. When it is necessary to move the steel, the electro-hydraulic push rod 31 is started, the piston rod is extended, and the rotating rod 22 is pushed to rotate around the bracket 21. The pulling grip 23 on the rotating rod 22 is lifted upward as the rotating rod 22 rotates to grab the steel. Then, the electro-hydraulic push rod 31 continues to push the rotating rod 22 to lift the steel to a certain height. Then, the steel is moved to the desired position through other equipment or mechanisms. When the steel reaches the destination, the piston rod of the electro-hydraulic push rod 31 retracts, the rotating rod 22 rotates in the opposite direction, and the puller 23 puts down the steel, completing the steel moving operation.

[0047] The specific implementation methods of the present application described above do not constitute a limitation on the protection scope of the present application. Any other corresponding changes and modifications made according to the technical concept of the present application should be included in the protection scope of the claims of the present application.
