Description

Technical Field

[0001] The present application relates to the technical field of large wire coils, and in particular to a large coil step-by-step conveying system. Background Art

[0002] As a core component of the metal processing industry, the coiled wire production technology is the key to supporting the development of many downstream manufacturing industries with its complex and precise production process chain. The technology starts with the smelting of raw materials. Through a carefully designed continuous casting process, the liquid metal is transformed into a continuous casting billet with a preliminary shape. Subsequently, the hot rolling process uses the plasticity of metal materials at high temperatures to further compress and reduce the rough billet, while improving the internal grain structure and enhancing the uniformity and density of the material. This process not only greatly improves the strength of the material, but also lays the foundation for subsequent cold processing. Next, the cooled wire enters the cold rolling stage, which is a key step in fine shaping and size control of the material. Through the precisely controlled cold rolling mill, the wire is further thinned to the predetermined specifications, while the surface quality and shape accuracy are significantly improved, meeting the strict requirements of different application scenarios. Finally, the carefully processed wire is fed into the large coil coiler, and the wire is tightly and evenly rolled into a large coil form through precisely controlled winding technology. At this point, the production process of coiled wire has not ended. Ensuring the safe and efficient transportation of large coils has become the last link in the industrial chain.

[0003] When existing large coils are transported externally, they are limited by the site and need to be efficiently transported in different tortuous directions. However, the existing conventional transport mechanisms are often long and straight. Once the layout is completed, it is not easy to adjust the transportation direction of the large coils. In addition, the large coils also need to be heat-dissipated during the transmission process to meet subsequent usage requirements after cooling down. Summary of the invention

[0004] This device provides a large coil step-by-step conveying system, and the specific implementation method is as follows:

[0005] A large coil step-by-step conveying system, comprising:

[0006] A walking beam for transporting large coils, with a coil unloading assembly provided at the near end of the two walking beam stations, comprising a frame and a lifting trolley slidably connected to the frame, with a grabbing member connected to the side of the lifting trolley, through which the large coil on the walking beam at the front station is transferred to the walking beam at the rear station;

[0007] Vertical winding core racks are evenly spaced along the length of the rear station walking beam, and the large coil is vertically inserted into the vertical winding core racks to achieve positioning and transportation during transfer.

[0008] Based on the above technical scheme, the unloading assembly is used to realize the transfer of large coils on different walking beams, and the vertical coil core frame can realize the stability of the large coils during continued transportation after transfer; the two walking beams can be parallel, and the frame can be provided with a rotating mechanism relative to the ground, the unloading assembly is arranged at the end of the front walking beam, and the rear walking beam is arranged on the side of the unloading assembly, and the large coils can be transferred between the two walking beams by rotating the frame ninety degrees.

[0009] Preferably, the walking beam is divided into a fixed beam and a movable beam, the fixed beam is divided into three sections laterally, the movable beam is arranged in the gaps between the three sections of the fixed beam, and the movable beam is lifted and lowered and moved laterally by a hydraulic cylinder.

[0010] Preferably, the walking beam is divided into a walking beam and a roller bed which are staggered in the longitudinal and transverse directions, the tracks of the two are vertically intersected, and the roller bed is arranged between the walking beam and the unloading assembly.

[0011] Based on the above technical solution, by setting vertically crossed walking beams and roller beds and using a coil unloading assembly that can lift the large coil, the directional transportation of the large coil is achieved in a limited space.

[0012] Preferably, the grabbing member comprises a mounting plate connected to the side of the lifting trolley, a plurality of claws are hingedly provided along the circumference of the mounting plate, and the ends of the claws are connected to the hydraulic cylinder through a connecting rod structure.

[0013] Preferably, the walking beam is provided with a cover body along its length direction, the middle of the cover body is hollow, and both sides are designed as open door-like structures for large coils to pass through.

[0014] Preferably, it also includes several groups of heat dissipation components arranged on the walking beam, which include a fan and a vertical through pipe. A guide component is provided above the vertical through pipe. Heat dissipation is performed when the large coil is transported between the vertical through pipe and the guide component. The transmission track of the walking beam is double-track, and the vertical through pipe is built in the center of the two, and the output end of the fan is connected to the vertical through pipe through a connecting pipe.

[0015] Based on the above technical solutions, combined with the coordinated work of the vertical through-pipe, the guide assembly and the large coil, a set of efficient cooling system is formed, which aims to quickly and evenly reduce the temperature of the large coil. The vertical through-pipe is combined with the large coil. When the cold airflow passes through the large coil, it contacts and replaces the wind on the inside of the large coil, which not only increases the heat dissipation area, but also improves the heat exchange efficiency; finally, through the integration of the guide assembly, the airflow or coolant is guided to flow around the outside of the large coil in the most optimized way to form a stable heat exchange environment, which not only avoids the energy loss caused by turbulence, but also ensures the uniformity of the heat dissipation process, so that the overall temperature of the large coil can be evenly reduced.

[0016] Preferably, the flow guide assembly includes a lifting seat, a horizontal plate is provided on the top of the lifting seat downward, and the horizontal plate corresponds vertically to the vertical through pipe.

[0017] Based on the above technical solutions, during the transportation of coiled wires, the lifting seat mainly achieves height adjustment through two common driving methods: screw motor drive and cylinder drive; by adjusting the distance between the horizontal plate and the coil, it can not only effectively guide the flow direction of the heat dissipation air and improve the cooling efficiency, but also can be flexibly adjusted according to the size and shape of the coil, ensuring that the quality and performance of the wire are optimally maintained during the entire processing process.

[0018] Preferably, the top of the cover body at the location of the heat dissipation component is set to be open.

[0019] Based on the above technical solution, the heat dissipation effect can be improved by setting the cover at the position of the heat dissipation component to be open at the top. At the same time, retaining the side partitions can effectively prevent the exposure of large coils, thereby avoiding scalding accidents.

[0020] In summary, this application includes the following beneficial technical effects:

[0024] 4. The present invention has a simple structure. A conventional lifting drive structure is built into the lifting seat, so that the distance between the horizontal plate and the large coil can be adjusted, and the direction of the heat dissipation air can be adjusted according to the size and height of the large coil.

[0039] The following is combined with Figure 1-9 This application is described in further detail.

[0040] The embodiment of the present application discloses a large coil step-by-step conveying system.

[0041] Example 1

[0042] Reference Figures 1 to 9 The present embodiment discloses a large coil step-by-step conveying system, including a stepping beam 2 and a roller bed 5 for transporting a large coil 8, the tracks of the two intersect vertically, and the roller bed 5 is arranged between the stepping beam 2 and the coil unloading assembly 4, the coil unloading assembly 4 includes a frame 401 and a lifting trolley 402 slidably connected to the frame 401, and a grabbing member 403 is connected to the side of the lifting trolley 402. In this structure, the roller bed 5 is equidistantly provided with vertical coil core frames 501 along its length direction, and the large coil 8 is vertically inserted into the vertical coil core frame 501 to realize positioning and conveying during transportation.

[0043] The grabbing member 403 includes a mounting plate 4031 connected to the side of the lifting trolley 402 , a plurality of claws 4032 are hingedly provided along the circumference of the mounting plate 4031 , and the ends of the claws 4032 are connected to the hydraulic cylinder 4033 through a connecting rod structure.

[0044] Example 2

[0045] Reference Figures 4 to 8 , and based on Example 1, this embodiment also provides a large coil step-by-step conveying system, which also includes six groups of heat dissipation components 1 arranged on the walking beam 2, and the walking beam 2 is covered with a cover body 3 along its length direction. The two sides of the cover body 3 are designed to be an open structure for the large coil 8 to pass through, and the front and rear openings thereof are respectively an inlet 201 and an outlet 202. The cover body 3 is located at the position of the heat dissipation component 1, and the top is set to be open. In this structure, the heat dissipation component 1 includes a fan 101 and a vertical through pipe 103, and a guide component 6 is arranged above the vertical through pipe 103. When the large coil 8 is transported between the vertical through pipe 103 and the guide component 6, heat dissipation treatment is performed.

[0046] The transmission track of the walking beam 2 is double-track, the vertical through pipe 103 is built in the center of the two, and the output end of the fan 101 is connected to the vertical through pipe 103 through the connecting pipe 102. In this structure, the guide component 6 includes a lifting seat 602, a horizontal plate 601 is provided on the top downward, and the horizontal plate 601 corresponds vertically to the vertical through pipe 103.

[0047] The specific implementation process is as follows: the large coil 8 is transported from the inlet 201 to the walking beam 2 and gradually transported forward, and each group includes six large coils 8; when the large coil 8 moves to the designated position on the walking beam 2, the lifting seat 602 drives the horizontal plate 601 to descend in height, and a gap is left between the horizontal plate 601 and the top of the large coil 8; the fan 101 is started, and the airflow passes through the connecting pipe 102, the vertical through pipe 103 and the inner side of the large coil 8 upward, impacts the horizontal plate 601 and then acts downward on the outer side of the large coil 8; during this period, the gas exchanges heat with the inner side of the large coil 8 when flowing through it.

[0048] The subsequent large coil 8 continues to be transported forward along the walking beam 2. After arriving at the transfer position, the conventional lifting screw-type driving structure in the frame 401 causes the lifting trolley 402 to fall, and at this time, the clamping claw 4032 descends along the outer side of the outer side of the large coil 8; after reaching the bottom of the large coil 8, the hydraulic cylinder 4033 extends the air arm to make the clamping claw 4032 clamp the bottom of the large coil 8 inward; after the lifting trolley 402 is lifted up with the large coil 8, the roller bed 5 moves forward, causing the vertical winding core frame 501 to correspond axially with the large coil 8; then the lifting trolley 402 falls with the large coil 8 so that the large coil 8 is mounted outside the vertical winding core frame 501; after the lifting trolley 402 is lifted up again, the roller bed 5 takes the large coil 8 forward, thereby completing the steering and transportation of the large coil 8.

[0049] Many other changes and modifications may be made without departing from the concept and scope of the present invention.It should be understood that the present invention is not limited to the specific embodiments, and the scope of the present invention is defined by the appended claims.
