Description

Technical Field

[0001] The utility model relates to the technical field of blast furnace material transportation, in particular to a blast furnace tube belt machine turnover control device. Background Art

[0002] The main raw materials for blast furnace ironmaking include high-basicity sintered ore, low-basicity sintered ore, pelletized ore, lump ore, etc. The returned materials include coke powder, returned ore, dust ash, etc. According to environmental protection requirements, bulk materials used and produced by blast furnaces need to be transported in a clean manner. At present, most of the materials in blast furnaces are transported by pipe-belt conveyors to solve the dust problem during the transportation of bulk materials.

[0003] When bulk materials are transported by a belt conveyor, the working principle of the belt conveyor is to wrap the bulk materials in it through belt curling to achieve the purpose of closed transportation. However, it has the following disadvantages: the bulk materials generated by the blast furnace are supplied non-continuously. When there is less material above the belt conveyor, the belt of the belt conveyor is prone to flipping before curling. It is extremely difficult to recover after the belt flips, which not only affects the transportation of materials, but also causes damage to the equipment. Utility Model Content

[0006] Preferably, the distance between the bottom surfaces of the two pressing wheels and the belt of the belt conveyor body is 5 to 10 cm.

[0007] Preferably, first U-shaped plates are fixed to the left and right sides of the inner walls of a plurality of the U-shaped frames, and first rollers are detachably provided inside two of the first U-shaped plates.

[0010] Preferably, an alarm is fixed to the top surface of the support plate, the alarm is electrically connected to the proximity switch, and the alarm is electrically connected to the PLC controller.

[0011] Compared with the prior art, a blast furnace belt conveyor turning control device using the above technical solution has the following beneficial effects:

[0012] 1. When the belt of the belt conveyor body tends to flip during use, the machine can be stopped in time to avoid the flipping problem, thereby avoiding the safety hazards caused by the emergency disposal of the belt conveyor body system, preventing the belt flipping from affecting material transportation and damage, and thus reducing the workload of employees;

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 5 As shown, a blast furnace tube and belt machine flip control device includes a support plate 1, which is arranged above the tube and belt machine body 2, a bracket 3 is fixed to the bottom surface of the support plate 1, a PLC controller is fixed to the right side of the outer wall of the bracket 3, the PLC controller is electrically connected to a computer (the computer is not shown in the figure), the tube and belt machine body 2 is arranged inside the bracket 3, the tube and belt machine body 2 is electrically connected to the PLC controller, a plurality of U-shaped frames 4 are fixed inside the bracket 3, two rotating holes 5 are opened on the top surface of the support plate 1, pressure wheels 6 are rotatably arranged inside the two rotating holes 5, and two proximity switches 7 are fixed to the top surface of the support plate 1, and the two proximity switches 7 are electrically connected to the PLC controller respectively.

[0023] During use, the staff first installs the support plate 1 on the flat belt section before the pipe conveyor body 2 is curled, and the material is transported through the belt of the pipe conveyor body 2. When the belt of the pipe conveyor body 2 shows a tendency to flip, the edge of the belt rolls up and drives the pressure wheel 6 to rotate. At this time, the proximity switch 7 is activated to trigger the belt flip fault alarm, and the signal is transmitted to the PLC controller at the same time, and the pipe conveyor body 2 with a flip trend is chained and shut down. When the belt of the pipe conveyor body 2 shows a tendency to flip, it can be shut down in time, which is conducive to avoiding the occurrence of flipping problems, thereby avoiding the safety hazards caused by the emergency disposal of the pipe conveyor body 2 system, and preventing the belt flip from affecting material transportation and damage, thereby reducing the workload of employees.

[0024] like Figure 1-Figure 4 As shown, the distance between the bottom surfaces of the two pressure wheels 6 and the belt of the belt conveyor body 2 is 5 to 10 cm, and the first U-shaped plates 8 are fixed on the left and right sides of the inner walls of the plurality of U-shaped frames 4, and the first rollers 9 are detachably provided inside the two first U-shaped plates 8.

[0025] During use, the first U-shaped plate 8 and the first roller 9 are used to support and guide the belt of the belt conveyor body 2, ensuring that the belt of the belt conveyor body 2 maintains the correct position during operation, helps avoid deviation from the predetermined trajectory, and ensures that the belt remains stable during operation.

[0026] like Figure 2 and Figure 4 As shown, the top and bottom surfaces of the two first U-shaped plates 8 are respectively provided with connecting holes 10, the top and bottom ends of the two first rollers 9 are respectively provided with fixing grooves 11, springs 12 are respectively fixed inside the two fixing grooves 11, and rotating columns 13 are respectively fixed at the outer ends of the two springs 12, and the two rotating columns 13 are respectively rotatably arranged in the two connecting holes 10.

[0027] During use, when the staff needs to install the first roller 9, they first squeeze the two rotating columns 13. At this time, the spring 12 is in a compressed state, so that the two rotating columns 13 are slidably inserted in the two fixed grooves 11 respectively, and then the first roller 9 is placed inside the first U-shaped plate 8. When the rotating columns 13 correspond to the connecting holes 10, the spring 12 is used to automatically reset the rotating columns 13, so that the rotating columns 13 are slidably inserted in the connecting holes 10, and the installation of the first roller 9 is completed; conversely, when the staff needs to disassemble the first roller 9, they squeeze the two rotating columns 13 so that the rotating columns 13 are detached from the inside of the connecting holes 10, so that the rotating columns 13 are slidably inserted in the fixed grooves 11, and then the first roller 9 can be disassembled, which is convenient for the staff to disassemble and assemble the first roller 9, thereby facilitating the staff to maintain or replace the first roller 9.

[0028] like Figure 1-Figure 5 As shown, the inner bottom surfaces of several U-shaped frames 4 are respectively fixed with second U-shaped plates 14, the interiors of several second U-shaped plates 14 are respectively rotatably provided with second rollers 15, and the top surface of the support plate 1 is fixed with an alarm 16, the alarm 16 is electrically connected to the proximity switch 7, and the alarm 16 is electrically connected to the PLC controller.

[0029] In use, the second U-shaped plate 14 and the second roller 15 are used to support the belt of the belt conveyor body 2 and the weight of the material carried thereon, which is helpful to reduce the resistance of the belt when it is running, ensure the stability of the belt, help prevent the belt from sagging, maintain the tension and shape of the belt, and thus ensure the conveying efficiency and stability. When the belt conveyor body 2 fails, the proximity switch 7 is activated to trigger the belt flip failure alarm, and the signal is transmitted to the alarm 16. At this time, the alarm 16 transmits the signal to the PLC controller, and the PLC controller displays the alarm signal on the computer screen, so as to promptly notify the staff to take measures and handle them in time.
