Description

Technical Field

[0001] This utility model relates to the field of metallurgical machinery and equipment technology, specifically to a billet loading and unloading system that prevents scratches. Background Technology

[0002] Currently, in the metal smelting production process, when the heating furnace is in an accident state, the hot steel billets from the continuous casting machine are usually transferred to the hot conveying roller conveyor via a rotating roller conveyor. Then, the steel billets on the hot conveying roller conveyor are pushed to the fixed hot billet buffering platform for buffering by the steel pushing platform, thus completing the feeding action.

[0003] At least the following defects and deficiencies exist: First, during the steel billet transfer process, the steel billet never separates from the roller table surface or the upper surface of the fixed hot billet buffer platform. Therefore, the steel billet is severely scratched. Moreover, the more steel billets are buffered, the longer the initial steel billet slides on the buffer platform, and the more severe the scratches. This defect often limits the buffer volume of the fixed hot billet buffer platform.

[0004] Secondly, according to production needs, the aforementioned billets from the accident need to be transported to the heating furnace for the next process. Usually, a disk crane is used to transfer the billets on the fixed hot billet buffer platform to the hot conveyor roller conveyor to complete the unloading action. This process usually occupies a lot of overhead crane resources, and there is also the possibility of damaging the hot conveyor roller conveyor. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a billet loading and unloading system without scratches, which realizes continuous loading and unloading of billets without damage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A non-scratching billet loading and unloading system includes a reclaimer, a conveyor roller conveyor, and a loading / unloading platform. The reclaimer is located on one side of the conveyor roller conveyor, and the loading / unloading platform is located on the other side. The loading / unloading platform includes a loading platform and a pushing device, and the reclaimer includes a reclaiming rod, a lifting device, and a translating device. The lifting device drives the reclaiming rod to rise and fall, and the translating device drives the reclaiming rod to translate, thereby placing the billet on the conveyor roller conveyor onto the loading platform. The pushing device delivers the billet to the rear of the loading platform to achieve loading. The pushing device delivers the billet from the rear of the loading platform to the front of the loading platform, and the reclaimer places the billet on the conveyor roller conveyor to achieve unloading.

[0008] Furthermore, the lifting device includes a crank-rocker mechanism, a lifting hydraulic cylinder, and a roller; the roller is hinged to one end of the crank-rocker mechanism, the other end of the crank-rocker mechanism is hinged to the piston rod of the lifting hydraulic cylinder, and the roller is tumbledly connected to the material picking rod.

[0009] Furthermore, the translation device includes a translation hydraulic cylinder and a translation wheel; the translation hydraulic cylinder is hinged to the material-taking rod, and the translation wheel is tumbled to the material-taking rod.

[0010] Furthermore, there are multiple material picking rods arranged in parallel to each other, with the material picking rods perpendicular to the center line of the conveyor rollers. Each material picking rod has a material picking block at its end, and the material picking blocks of the multiple material picking rods are flush.

[0011] Furthermore, the material-taking rods are connected by a connecting beam, which is parallel to the center line of the conveyor roller conveyor.

[0012] Furthermore, the material platform is composed of multiple parallel fixed beams, which are perpendicular to the center line of the conveyor roller conveyor.

[0013] Furthermore, the feeding device includes a crossbeam, a movable beam, an eccentric wheel, and a motor; multiple movable beams are fixedly connected to the crossbeam in parallel to each other, the crossbeam is parallel to the center line of the conveyor roller, the eccentric wheel is installed on the crossbeam, the motor drives the eccentric wheel to rotate, and thus drives the movable beam to swing back and forth.

[0014] Furthermore, the eccentric wheels are arranged in multiple rows, with each row having multiple eccentric wheels and a reducer. The multiple eccentric wheels are connected and driven by a reducer; the reducers in different rows are connected in series and driven to operate synchronously by a motor.

[0015] Furthermore, the eccentric wheel is mounted on the crankshaft, the crankshafts are connected to each other by couplings, the crankshafts are connected to the reducers by couplings, and the reducers in different rows are connected in series by couplings.

[0016] Compared with the prior art, the present invention has at least the following technical effects or advantages:

[0017] 1. The material handling machine of this utility model is set on one side of the conveying roller conveyor (a hot conveying roller conveyor in a specific embodiment), and the loading and unloading platform machine is set on the other side of the conveying roller conveyor; the lifting device of the material handling machine drives the material handling rod to rise and fall, and the translation device drives the sampling rod to translate, thereby placing the billet on the conveying roller conveyor onto the platform. The pushing device sends the billet to the rear of the platform to realize loading; the pushing device sends the billet from the rear of the platform to the front of the platform, and the material handling machine places the billet on the conveying roller conveyor to realize unloading.

[0018] This invention achieves loading and unloading through the coordinated operation of a loading / unloading platform, a hot conveyor roller conveyor, and a reclaimer. The entire process is mechanized, meaning that regardless of whether the hot billet is in the loading or unloading state, it can achieve scratch-free automatic loading and unloading. It is well adapted to actual site conditions and successfully solves problems such as multiple billets slipping off simultaneously during unloading from the original fixed hot billet buffer platform, one end of a billet still on the platform while the other end has already slid onto the hot conveyor roller conveyor, and billets frequently damaging the conveyor roller conveyor when sliding down. It also avoids scratching the billets and wasting overhead crane resources during loading and unloading, achieving a non-destructive loading and unloading function that meets usage requirements and production needs.

[0019] 2. The loading and unloading platform of this utility model is located on the other side of the conveyor roller conveyor. The loading and unloading platform is equipped with a pushing device, and the loading and unloading operations can be completed by the back-and-forth swing of the movable beam. It can temporarily complete the loading and unloading operations by pushing the material when the reclaimer fails and cannot reclaim steel normally. It can adapt well to the actual site conditions and improve the practicality of the device.

[0020] 3. This utility model features multiple rows of eccentric wheels, with each row equipped with multiple eccentric wheels and a reducer. The multiple eccentric wheels are connected and driven by a single reducer; reducers in different rows are connected in series and driven synchronously by a single motor. This ensures that all blanks on the loading and unloading platforms can move at a fixed step distance.

[0021] 4. In this invention, multiple picking rods are arranged parallel to each other, with the picking rods perpendicular to the center line of the conveyor rollers. Each picking rod has a picking block at its end, and the picking blocks of the multiple picking rods are flush. During the feeding operation, the alignment process of each picking rod also straightens the side-bent hot billet. Attached Figure Description

[0035] like Figure 1-6 As shown, a non-scratching billet loading and unloading system includes a reclaimer 2, a hot conveyor roller conveyor 1 (conveying roller conveyor), and a loading / unloading platform 3. The hot conveyor roller conveyor 1 consists of multiple parallel conveying rollers arranged in a row, with the axes of the multiple conveying rollers parallel to each other and perpendicular to the center line 4 of the hot conveyor roller conveyor. The material feeding direction is shown by the arrow. The reclaimer 2 is located at the rear of the hot conveyor roller conveyor 1, and the loading / unloading platform 3 is located at the front of the hot conveyor roller conveyor 1.

[0036] like Figure 3 , Figure 4 As shown, the material handling machine 2 includes material handling rods 21, connecting beams 22, lifting devices 23, and translation devices 24. In this embodiment, there are 5 material handling rods 21, which are parallel to each other and spaced at the same distance. The material handling rods 21 are made of H-beams and are perpendicular to the center line 4 of the hot conveying roller conveyor. The top end of the material handling rods 21 is provided with a material handling block 211, which is L-shaped. The material handling blocks 211 of the 5 material handling rods are flush.

[0037] The material picking rods 21 are connected by connecting beams 22, which are parallel to the center line 4 of the hot conveyor roller. In this embodiment, two rows of connecting beams 22 are provided, and the material picking rods 21 and the connecting beams 22 form a swing arm frame. The connecting beams 22 increase the lateral and longitudinal stiffness of the material picking rods 21, thereby increasing the flatness and overall integrity of the structure.

[0038] The lifting device 23 includes a crank-rocker mechanism 231, a lifting hydraulic cylinder 232, and a roller 233. The roller 233 is hinged to the left end of the crank-rocker mechanism, and the bottom of the crank-rocker mechanism is hinged to the ground. The left end of the crank-rocker mechanism is hinged to the piston rod of the lifting hydraulic cylinder. The roller 233 is rolled along the bottom of the material-retrieving rod 21. The extension and retraction of the lifting hydraulic cylinder 232 drives the rocker arm of the crank-rocker mechanism 231 to swing, which in turn drives the roller 233 to lift or lower the material-retrieving rod 21, thereby realizing the lifting and lowering of the material-retrieving rod 21.

[0039] The translation device 24 includes a translation hydraulic cylinder 241 and translation wheels 242. The piston rod end of the translation hydraulic cylinder 241 is hinged to the bottom surface of the picking rod via a hinge seat. The translation wheels 242 are mounted on both sides of the picking rod 21 and are in rolling connection with the picking rod 21. The translation wheels 242 enable the picking rod 21 to move smoothly back and forth and reduce friction. The extension and retraction of the piston rod of the translation hydraulic cylinder 241 drives the picking rod 21 to move back and forth.

[0040] like Figure 5 , Figure 6 As shown, the loading and unloading platform machine 3 includes a loading platform and a pushing device. The loading platform is composed of a number of parallel fixed beams 31 with equal spacing. The fixed beams 31 are perpendicular to the center line 4 of the hot conveying roller conveyor.

[0041] The feeding device includes a crossbeam 33, movable beams 32, eccentric wheels 35, and a motor 34. In this embodiment, seven movable beams 32 are fixed to the top surface of the crossbeam 33 in parallel to each other. The crossbeam 33 is parallel to the center line 4 of the hot conveying roller conveyor, and there are two parallel crossbeams 33.

[0042] Three eccentric wheels 35 are arranged in a row and evenly distributed at the bottom of the crossbeam 33. The eccentric wheels 35 are mounted on the crankshaft 36, which has bearings at both ends. The bearings are installed in bearing housings, and the crankshafts 36 are connected to each other by a coupling 37. The right crankshaft is connected to the reducer 38 by a coupling 37, and the reducers 38 in the front and rear rows are connected in series by couplings 37. The reducers 38 are connected to the motor 34. One variable frequency motor drives two reducers to operate synchronously, which drives the crankshaft 36 to rotate synchronously, and drives the seven movable beams 32 to swing back and forth synchronously.

[0043] The working principle and process of this utility model are as follows:

[0044] When no material signal is received from the material detection switch on the hot conveyor roller 1, the lifting device 23 and the translation device 24 in the reclaimer 2 are in the initial state, that is, the reclaiming rod 21 in the reclaimer 2 is in the most retracted and lowest position; the loading and unloading platform 3 is not started.

[0045] When the material detection switch on the hot conveyor roller 1 receives a material presence signal and the billet 5 is already stopped on the hot conveyor roller 1, the lifting device 23 in the reclaimer 2 is activated, and the reclaiming rod 21 rises to be flush with the surface of the hot conveyor roller 1. Then, the translation device 24 is activated, and the reclaiming rod 21 advances and continuously approaches the billet 5 until the reclaiming blocks 211 on each reclaiming rod 21 are in complete contact with the billet 5. This alignment process of the reclaiming rod 21 is also a process of straightening the hot billet. Subsequently, the lifting device 23 in the reclaimer 2 continues to operate, and the reclaiming rod 21 continues to lift the billet 5 with it until it is completely detached from the roller surface. Under the action of the translation device 24, the billet 5 is placed on the material platform of the upper and lower material platform frame 3, achieving non-destructive feeding.

[0046] After receiving the incoming material signal, the motor 34 starts and reverses, driving the movable beam 34 to swing, moving the billet transported by the take-up machine 2 to the rear of the material platform (away from the center line 4 of the hot conveying roller) according to the specified step distance, until the material platform is full of billets 5, and then the feeding stops.

[0047] When a production instruction is received to unload the billet 5 from the loading / unloading platform 3, the motor 34 starts and rotates forward, driving the movable beam 34 to swing and transport the billet 5 from its platform to the front end of the fixed beam 31. At this time, the lifting device 23 in the reclaimer 2 starts, and the reclaiming rod 21 rises to be flush with the upper surface of the fixed beam 31. Then, the translation device 24 starts, and the reclaiming rod 21 moves forward, continuously approaching the billet 5, until the reclaiming blocks 211 on each reclaiming rod 21 are in complete contact with the billet 5. Subsequently, the lifting device 23 in the reclaimer 2 continues to operate, and the reclaiming rod 21 continues to lift with the billet 5 until it is completely detached from the upper surface of the fixed beam 31. Under the action of the translation device 24, the billet 5 is placed on the hot conveyor roller 1, achieving non-destructive unloading.

[0048] The loading and unloading platform 3 of this utility model is located on the other side of the hot conveyor roller conveyor 1. The loading and unloading platform 3 is equipped with a pushing device, and the loading and unloading operations can be completed by swinging the movable beam back and forth. It can temporarily complete the loading and unloading operations by pushing the device when the reclaimer fails and cannot reclaim steel normally. It can adapt well to the actual site conditions and improve the practicality of the device.

[0049] This utility model features multiple rows of eccentric wheels 35, with each row having multiple eccentric wheels 35 connected to a reducer 38. The multiple eccentric wheels 35 are driven by the reducer 38; the reducers 38 in different rows are connected in series and driven synchronously by a motor 34. This ensures that all blanks on the loading and unloading platforms can move at a fixed step distance.

[0050] In this invention, multiple material-picking rods 21 are arranged parallel to each other, with each rod 21 perpendicular to the center line 4 of the hot conveyor roller. Each rod 21 has a material-picking block 211 at its end, and the material-picking blocks of the multiple rods are flush. During the feeding operation, the alignment process of each material-picking rod 21 also straightens the side-bent hot billet.

[0051] This invention achieves loading and unloading through the cooperation of the loading / unloading platform 3, the hot conveying roller conveyor 1, and the unloading machine 2. The entire process is mechanized, meaning that regardless of whether the hot billet is in the loading or unloading state, it can achieve scratch-free automatic loading and unloading. It is well adapted to actual site conditions and successfully solves the problems of multiple billets slipping off simultaneously during the unloading process of the original fixed hot billet buffer platform, one end of a billet still on the platform while the other end has already slid onto the hot conveying roller conveyor, and billets frequently damaging the conveyor conveyor when sliding down. At the same time, it avoids scratching the billets and wasting overhead crane resources during loading and unloading, achieving a non-destructive loading and unloading function that meets the usage requirements and production needs.

[0052] The scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
