Description

Technical Field

[0001] This utility model relates to the field of steel coil winding technology, and more specifically, to a protective device for winding heat insulation plates. Background Technology

[0002] During the production process, the strip steel is coiled into coil 01 on the coiler, and then transported to the pallet system for transporting coil 01 via the uncoiling trolley 02. The pallet system then transports coil 01 to the finished product warehouse. In the coiling area, since the coiling temperature of coil 01 is typically around 700 degrees Celsius, it is difficult for operators to approach during troubleshooting. Therefore, heat insulation panels 03 are installed in the coiling area. Figure 1 As shown.

[0003] If the coiler malfunctions, for example, if the coil 01 cannot be wound into shape due to loss of tension, the operator needs to manually operate the equipment to remove the abnormal coil 01 from the coiler drum and move it to the unwinding trolley 02. Figure 1 The steel coil 01, located at the bottom, is moved to the uncoiling trolley 02. Then, the operator directs the crane to lift the abnormal steel coil 01 from the air. However, due to the irregular shape of the steel coil 01, the tail of the steel coil 01 is swaying out. After the steel coil 01 is lifted by the crane, it is easy for it to sway from side to side, causing the steel coil 01 to easily deviate to one side and hit the heat insulation plate 03. Figure 1 The steel coil 01 located at the top collided with the heat insulation plate 03 on the left, ultimately damaging the heat insulation plate 03 and affecting its performance and service life.

[0004] In summary, how to develop a protective device that prevents steel coils from impacting the heat insulation plate when they are abnormally lifted by a crane is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a protective device for winding heat insulation plates, which can prevent steel coils from hitting the heat insulation plates when they are abnormally lifted by a crane.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A protective device for winding a heat insulation board, comprising:

[0008] The heat insulation board includes two vertically placed L-shaped plates with an L-shaped cross-section. The two L-shaped plates are located on both sides of the steel coil winding area and are distributed in a figure-eight shape.

[0009] Tracks are provided on the ground on both sides of the steel coil winding area;

[0010] A conveying device is disposed below the heat insulation plate, the conveying device including rollers that roll along the track.

[0011] In one embodiment, the conveying device includes three rollers respectively located below the three vertices of the L-shaped plate, two of the rollers being coaxial and connected by a connecting shaft, and the other roller being a free roller.

[0012] In one embodiment, a drive motor is mounted on the lower part of the heat insulation plate, and the drive motor is connected to two coaxial rollers via the connecting shaft.

[0013] In one embodiment, the drive motor and the power supply are connected via a power cable, the power supply and the PLC are connected via a control cable, and the PLC and the HMI system are connected via a communication cable.

[0014] In one embodiment, the HMI system's operation screen includes a left-shift button and a right-shift button, which respectively control the drive motor to run or reverse, so that the connecting shaft drives the roller to rotate or reverse, and correspondingly pushes the heat insulation plate to move to the left or right.

[0015] In one embodiment, the HMI system's operation screen also includes a stop button. When the operator clicks the stop button, the PLC receives the instruction from the HMI system and controls the drive motor to stop running.

[0016] When using the protective device for winding heat insulation plates provided by this utility model, if the winding machine loses tension and the steel coil cannot be wound into shape, the operator needs to manually operate the equipment to remove the abnormal steel coil from the winding machine's drum and onto the unloading trolley. At this time, the operator directs the crane to lift the abnormal steel coil away from the air. However, due to the irregular shape of the steel coil, the tail of the steel coil may swing out, making it prone to swaying left and right after being lifted by the crane. In this case, the operator can use the conveying device to move the heat insulation plate located on the left side of the steel coil winding area to the left along the track, and the heat insulation plate located on the right side of the steel coil winding area to the right along the track, so that both heat insulation plates are away from the steel coil, avoiding the possibility of the abnormal steel coil hitting the heat insulation plates when being lifted, which could damage the heat insulation plates and affect their performance and service life.

[0017] In summary, the protective device for winding the heat insulation plate provided by this utility model can prevent the steel coil from hitting the heat insulation plate when it is abnormally lifted by a crane. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The core of this utility model is to provide a protective device for winding heat insulation plates, which can prevent steel coils from hitting the heat insulation plates when they are abnormally lifted by a crane.

[0027] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the protective device for winding the heat insulation plate, located on the left side of the steel coil winding area provided by this utility model.

[0028] This specific embodiment provides a protective device for winding up a heat insulation board. Figure 2 The protective device for winding the heat insulation plate is located only on the left side of the steel coil winding area, while a corresponding device is installed on the right side of the steel coil winding area. Figure 2 A protective device for winding up a heat insulation board, comprising:

[0029] The heat insulation board 1 includes two vertically placed L-shaped boards with an L-shaped cross-section. The two L-shaped boards are located on both sides of the steel coil winding area and are distributed in a figure-eight shape.

[0030] Track 2 is located on the ground on both sides of the steel coil winding area;

[0031] The conveying device 3 is located below the heat insulation plate 1 and includes rollers 31 that roll along the track 2.

[0032] It should be noted that the L-shaped plate refers to the heat insulation plate 1 having an L-shaped cross-section. The coil winding area refers to the area where the coil is transferred to the unloading trolley after being wound out by the coiler. Furthermore, when an abnormality occurs in the coil, a crane will lift the coil in the coil winding area. Therefore, two heat insulation plates 1 can be installed on each side of the coil winding area to prevent operators from having difficulty accessing the area when troubleshooting. Moreover, the two L-shaped plates are arranged in a V-shape, meaning that the vertical edges of the two heat insulation plates 1 are parallel, and their horizontal edges are aligned but facing away from each other.

[0033] In practical applications, the shape, structure, size, and material of the heat insulation board 1, track 2, and conveying device 3 can be determined according to the actual situation and needs.

[0034] When using the protective device for winding the heat insulation plate provided by this utility model, if the winding machine loses tension and the steel coil cannot be wound into shape, the operator needs to manually operate the equipment to remove the abnormal steel coil from the winding machine drum and to the unloading trolley. At this time, the operator directs the crane to lift the abnormal steel coil away from the air. However, due to the irregular shape of the steel coil, the tail of the steel coil is thrown out, and it is easy for the steel coil to swing left and right after being lifted by the crane. At this time, the operator can use the conveying device 3 to move the heat insulation plate 1 located on the left side of the steel coil winding area to the left along the track 2, and move the heat insulation plate 1 located on the right side of the steel coil winding area to the right along the track 2, so that both heat insulation plates 1 are away from the steel coil, avoiding the possibility that the abnormal steel coil may hit the heat insulation plate 1 when it is lifted, which would damage the heat insulation plate 1 and affect its performance and service life. This also effectively protects the equipment and reduces the equipment maintenance cost.

[0035] In summary, the protective device for winding the heat insulation plate provided by this utility model can prevent the steel coil from hitting the heat insulation plate 1 when the steel coil is abnormally lifted by a crane.

[0036] In one embodiment, the conveying device 3 includes three rollers 31 respectively located below the three vertices of the L-shaped plate. Two coaxial rollers 31 are connected by a connecting shaft 32, and the other roller 31 is a free roller. For example, two parallel tracks 2 can be set on the ground on both sides of the steel coil winding area, and all three rollers 31 can roll along the tracks 2 to realize the movement operation of the heat insulation plate 1 through the conveying device 3.

[0037] In one embodiment, a drive motor 33 is installed at the lower part of the heat insulation plate 1. The drive motor 33 is connected to two coaxial rollers 31 via a connecting shaft 32. Therefore, by controlling the operation of the drive motor 33, the connecting shaft 32 can be driven to rotate, thereby driving the two coaxial rollers 31 to roll along the track 2. The other roller 31 can roll synchronously with the rolling roller 31 to achieve smooth rolling of the L-shaped plate on the track 2.

[0038] In one embodiment, the drive motor 33 and the power supply 34 are connected by a power cable 35 so that the power supply 34 supplies power to the drive motor 33, enabling the drive motor 33 to operate. The power supply 34 and the PLC 36 are connected by a control cable 37 so that the PLC 36 can control the operation of the power supply 34. The PLC 36 and the HMI system 38 are connected by a communication cable 39 so that the PLC 36 can operate according to the instructions of the HMI system 38.

[0039] In one embodiment, the operation screen of the HMI system 38 is provided with a left-moving button and a right-moving button, which respectively control the drive motor 33 to run or run in reverse, so that the connecting shaft 32 drives the roller 31 to rotate or rotate in reverse, and correspondingly pushes the heat insulation plate 1 to move to the left or right.

[0040] It should be noted that the operation screen of HMI system 38 is equipped with a left-moving button and a right-moving button. In addition, a selection button (left heat insulation plate 1 or right heat insulation plate 1) can be added to the operation screen of HMI system 38, so that the operator can select the heat insulation plate 1 located on the left side of the steel coil winding area to move to the left, or select the heat insulation plate 1 located on the right side of the steel coil winding area to move to the left.

[0041] When the coiler loses tension and the steel coil cannot be wound into shape, the operator needs to manually operate the equipment to remove the abnormal steel coil from the coiler's drum and onto the unloading trolley. At this point, the operator can direct the crane to lift the abnormal steel coil away from the air. Due to the irregular shape of the steel coil, the tail of the coil may sway, making it prone to tilting left and right after being lifted by the crane.

[0042] At this time, the operator can select the left side heat insulation plate 1 button of HMI system 38, and then click the left shift button of HMI system 38. After receiving the instruction from HMI system 38, PLC 36 controls power supply 34 to start drive motor 33 located on the left side of the steel coil winding area according to program logic. That is, control drive motor 33 located on the left side of the steel coil winding area to work, drive connecting shaft 32 located on the left side of the steel coil winding area to rotate. The rotation of connecting shaft 32 drives two coaxial rollers 31 to rotate, and the free roller can roll synchronously with the rolling rollers 31 to push heat insulation plate 1 located on the left side of the steel coil winding area to move to the left. When heat insulation plate 1 located on the left side of the steel coil winding area moves to the left limit position under the drive of conveying device 3, PLC 36 controls power supply 34 to stop working.

[0043] Then, the operator can select the right-side heat insulation plate 1 button of the HMI system 38, and then click the right-shift button of the HMI system 38. After receiving the instruction from the HMI system 38, the PLC 36 controls the power supply 34 to start the drive motor 33 located on the right side of the steel coil winding area according to the program logic. That is, it controls the drive motor 33 located on the right side of the steel coil winding area to work, driving the connecting shaft 32 located on the right side of the steel coil winding area to rotate. The rotation of the connecting shaft 32 drives the two coaxial rollers 31 to rotate, and the free roller can roll synchronously with the rolling rollers 31 to push the heat insulation plate 1 located on the right side of the steel coil winding area to move to the right. When the heat insulation plate 1 located on the right side of the steel coil winding area moves to the right limit position under the drive of the conveying device 3, the PLC 36 controls the power supply 34 to stop working.

[0044] After the heat insulation plates 1 located on both sides of the steel coil winding area have been moved to a safe position, the operator directs the crane to lift the steel coil. After the steel coil is lifted out, the operator needs to control the heat insulation plates 1 to return to their original positions.

[0045] At this time, the operator can select the left side heat insulation plate 1 button of HMI system 38, and then click the right move button of HMI system 38. After receiving the instruction from HMI system 38, PLC 36 controls power supply 34 to start drive motor 33 located on the left side of the steel coil winding area according to program logic. That is, control drive motor 33 located on the left side of the steel coil winding area to work, drive connecting shaft 32 located on the left side of the steel coil winding area to rotate in the opposite direction. The rotation of connecting shaft 32 drives two coaxial rollers 31 to rotate in the opposite direction, and the free roller can roll synchronously with the rolling rollers 31 to push heat insulation plate 1 located on the left side of the steel coil winding area to move to the right. When heat insulation plate 1 located on the left side of the steel coil winding area moves to the initial position under the drive of conveying device 3, PLC 36 controls power supply 34 to stop working.

[0046] Then, the operator can select the right-side heat insulation plate 1 button of the HMI system 38, and then click the left-shift button of the HMI system 38. After receiving the instruction from the HMI system 38, the PLC 36 controls the power supply 34 to start the drive motor 33 located on the right side of the steel coil winding area according to the program logic. That is, it controls the drive motor 33 located on the right side of the steel coil winding area to work, driving the connecting shaft 32 located on the right side of the steel coil winding area to rotate in the opposite direction. The rotation of the connecting shaft 32 drives the two coaxial rollers 31 to rotate in the opposite direction, and the free roller can roll synchronously with the rolling rollers 31 to push the heat insulation plate 1 located on the right side of the steel coil winding area to move to the left. When the heat insulation plate 1 located on the right side of the steel coil winding area moves to the initial position under the drive of the conveying device 3, the PLC 36 controls the power supply 34 to stop working.

[0047] Once the heat insulation plates 1 located on the left and right sides of the steel coil winding area reach their initial positions, normal steel coil production operations can be resumed.

[0048] In one embodiment, the operation screen of the HMI system 38 is also equipped with a stop button. When the operator clicks the stop button, the PLC 36 receives the instruction from the HMI system 38 and controls the drive motor 33 to stop running.

[0049] When equipment malfunctions or safety hazards are discovered, the operator can click the stop button on the HMI system 38 screen to stop the movement of the insulation panel 1 at any time.
