Description

Technical Field

[0001] The utility model belongs to the technical field of bar bundling and conveying in the metallurgical industry, and particularly relates to a novel conveying device for bundled bars. Background Technique

[0002] After the bars are produced on the platform, the bars are first bundled on the platform, and then the bundled bars on the platform are transported by a conveying device through a blanking device. During this period, the bundled bars need to be weighed, and after passing the inspection, they are transported to the finished product area.

[0003] The lifting of the existing chain conveyor mostly adopts hydraulic cylinder drive. At least two hydraulic elevators drive the cross beam to lift, so that each section of the conveying rack is lifted on the cross beam, and then the bundled materials are dropped onto the weighing platform rack, so as to weigh the bundled materials on the weighing platform rack and then transport them; however, the existing hydraulic cylinder drive has poor synchronism, and the chain conveying racks are often not in the same plane after the platform rack is lifted, resulting in unstable operation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a novel conveying device for bundled bars, which solves the problems of poor synchronism of the existing hydraulic cylinder drive for lifting, and the chain conveying racks are often not in the same plane after the platform rack is lifted, resulting in unstable operation.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a novel conveying device for bundled bars, which includes a chain conveyor, a weighing platform rack, bundled materials and a lifting component. The chain conveyor includes a base, and multiple groups of the bases are provided. A driving shaft is rotatably connected between the multiple groups of bases. A driven gear is fixedly connected to the circumferential side of the middle part of the driving shaft. An installation shell is arranged on one side of one group of the bases. The driving shaft penetrates through the installation shell. The driven gear is arranged in the installation shell and is rotationally matched with it. A servo motor is installed on one side surface of the installation shell. The output end of the servo motor is fixedly connected with a driving gear. The driving gear meshes with the driven gear. Multiple groups of driving sprockets are fixedly connected to the circumferential side of the driving shaft. The first sprocket is arranged in the base and is rotationally matched with it. The lifting component includes a fixed outer shell. Multiple groups of the fixed outer shells are provided, and the number of the fixed outer shells is the same as the number of the bases. The fixed outer shells are arranged on the opposite sides of the bases.

[0007] A mating bevel gear is rotatably connected inside the fixed housing. A driving screw rod is threadedly connected inside the mating bevel gear. The driving screw rod is arranged inside the fixed housing and is slidably mated with it. One end of the driving screw rod is rotatably connected to a support rod. One end of the support rod is fixedly connected to a support seat. The support seat is arranged above the fixed housing. A mating seat is fixedly connected inside the support seat. A mating rod is rotatably connected inside the mating seat. A mating sprocket is fixedly connected to the circumferential side of the mating rod. A chain is installed between the mating sprocket and the driving sprocket, and a sprocket-chain structure is formed among the three. Chain plates are arranged on the surface of the chain.

[0008] Linking rods are rotatably connected to both sides of the fixed housing. One end of each of the two linking rods is fixedly connected to a driven bevel gear. The two driven bevel gears are respectively meshed with the mating bevel gear.

[0009] Multiple support frames are cross-arranged among multiple fixed housings. A conveying roller path is installed at the top of the support frame. A cross bar is fixedly connected inside the support frame. A bearing seat is fixedly connected to the surface of the cross bar. A long shaft is arranged inside the bearing seat. One end of the long shaft is hinged to a universal coupling. The other end of the universal coupling is hinged to the linking rod.

[0010] An installation frame is arranged on one side of one of the support frames. A reduction motor is installed inside the installation frame. A driving bevel gear is fixedly connected to the output end of the reduction motor. One end of the long shafts located on both sides of the reduction motor is fixedly connected to a linkage bevel gear. The two linkage bevel gears are respectively meshed with the driving bevel gear.

[0011] The weighing platform frame is arranged between the base and the fixed housing, and the weighing platform frame is arranged below the chain plate.

[0012] The bundled materials are arranged on the surface of the chain plate.

[0013] The utility model has the following beneficial effects:

[0014] The utility model is provided with a chain conveyor, a reduction motor, a long shaft, a universal coupling and a lifting assembly. When the chain conveyor is used to convey bundled materials and reaches the weighing platform, the chain conveyor is shut down and the reduction motor is started, so that the driving bevel gear drives two groups of linkage bevel gears to rotate. Then, the driven bevel gear is driven to rotate through the long shaft and the universal coupling, and the mating bevel gear is driven to rotate through the driven bevel gear, so that the mating bevel gear drives the driving screw to descend in the fixed housing, and then drives the support rod to move downward. Further, the support seat drives one end of the chain conveyor to move downward, so that the bundled materials fall onto the weighing platform for weighing. After weighing, the reduction motor rotates reversely, and under the cooperation of the long shaft and the universal coupling, the support seat rises, so as to drive the bundled materials to fall onto the chain conveyor and continue to be conveyed by the chain conveyor. With the cooperation of each part, the support seat is forced to be mechanically synchronized, and the height after lifting is always in a plane, and the operation is stable. Moreover, this design does not use hydraulic pressure, and at the same time improves the economy of equipment maintenance.

[0015] Of course, it is not necessary for any product implementing the utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
