Description

Technical Field

[0001] This application relates to belt conveyor cleaning technology, and in particular to an intelligent control system for belt cleaning based on remote operation and maintenance. Background Technology

[0002] During the material transport process of a belt conveyor, if residual material enters the bearing housing of the drum or idler, it will accelerate bearing wear. Material adhering to the surface of the drum or idler will tear and fray the conveyor belt surface, accelerating the wear and damage of the conveyor belt. If the material adheres to and clumps on the surface of the deflection drum or vertical tension drum at the tail of the belt conveyor, it will cause the conveyor belt to run off-track, increase the wear of the conveyor belt, and even tear the drum rubber layer, resulting in serious consequences.

[0003] The belt conveyor cleaners currently in use are mounted on a frame. First, the height of the frame is adjusted so that the cleaning part of the cleaner can fit tightly against the belt surface. After adjustment, the cleaner is fixed on the frame. When there is accumulated material on the belt surface, it is cleaned by the cleaning part. However, the above-mentioned cleaners have the following defects: when the cleaner blades wear, the springs must be manually tightened to ensure that the blades press firmly against the belt and achieve the cleaning effect. This often leads to serious personal injury accidents.

[0004] Therefore, the applicant hypothesizes that if the sweeper could automatically compensate for the wear of the blades and trigger an alarm signal when the blades are excessively worn to remind the user to replace them, the cleaning effect could be effectively guaranteed and the performance would be good. Summary of the Invention

[0005] The purpose of this application is to solve the problem that when the blades of a sweeper wear out, the springs must be manually tightened to ensure that the blades are pressed firmly against the belt and achieve a sweeping effect, which often leads to serious personal injury accidents.

[0006] Compared with existing technologies, this invention provides a remote operation and maintenance-based intelligent control system for belt sweeping, including a frame, rollers mounted on the frame, sweeping blades for cleaning the conveyor belt on the rollers, and a sweeping system for controlling the operation of the sweeping blades. The sweeping blades are composed of multiple blade assemblies. The sweeping system includes a processing module and a cloud module, with the cloud module communicating with the processing module via a 4G module. One end of the sweeping blade is equipped with an actuator electrically connected to the processing module, and the output end of the actuator is equipped with a torsion sensor electrically connected to the processing module to acquire the actuator torque and transmit the torque information to the processing module. The actuator is fixed to the frame, and a rod is horizontally corresponding to the actuator's drive end. One end of the rod is connected to the actuator via a coupling. An angle sensor electrically connected to the processing module is installed inside the actuator.

[0007] When the torque sensor detects excessive wear of the sweeping blades and triggers an alarm, the alarm status can be displayed on both mobile phones and PCs when connected to the internet, truly achieving "unattended operation" and enabling remote maintenance. The processing module automatically determines whether the sweeping blades should be pressurized or depressurized under the current condition, and then controls the pressure between the sweeping blades and the conveyor belt to always be within the set range, thereby ensuring that the sweeping blades and the conveyor belt are always in close contact and maintaining a constant pressure between the sweeping blades and the conveyor belt, thus extending the service life of the sweeping blades and the conveyor belt.

[0008] Optionally, the blade assembly includes multiple spaced-apart rotating rods rotatably connected to the rod body, with detachable cleaning blades mounted on the top of the rotating rods, and torsion springs fitted at both ends of the rotating rods.

[0009] Furthermore, an upper gear is fixed to one end of the rotating rod, a lower gear meshes with the bottom of the upper gear, a rack meshes with the bottom of the lower gear, and the rack is slidably connected to the rod body.

[0010] Furthermore, a metal slider is fixed to one end of the rack, and a resistor is provided below the metal slider, with the metal slider and the resistor being slidably connected.

[0011] Furthermore, a repulsion block is fixed at the bottom of the rotating rod, and an electromagnet corresponding to the repulsion block is fixed on the inner wall of the rod. The electromagnet and the repulsion block have the same magnetism. A resistor is connected to the electromagnet through a wire to control the magnitude of the electromagnet's magnetic force. A resistance sensor is installed at the resistor's output end, and the resistance sensor is electrically connected to the processing module.

[0012] Optionally, an alarm assembly is installed at the end of the rotating rod away from the upper gear. The alarm assembly includes a control lever, and the control lever and the rotating rod are connected by a drive belt.

[0013] Furthermore, a first magnet is installed at the end of the control lever away from the rotating lever.

[0014] Furthermore, multiple reminder layers are slidably connected inside the rod, and the reminder layers are horizontally aligned with the control rod. Magnetic particles opposite to the first magnet are fixed to the side of the reminder layer facing the control rod. The reminder layers and the rod are connected by a compression spring.

[0015] Furthermore, multiple reminder windows corresponding to the reminder layer are fixed on the outside of the pole, and the reminder windows are made of frosted material.

[0016] Optionally, the cleaning blades are made of ultra-high molecular weight polyurethane material with a molecular weight of not less than 10,000.

[0017] Compared to existing technologies, the advantages of this application are:

[0018] (1) When the torque sensor detects excessive wear of the sweeping blades, the alarm status can be displayed on both the mobile phone and PC when connected to the network, truly achieving "unattended operation" and realizing remote operation and maintenance. The processing module automatically determines whether the sweeping blades should be pressurized or depressurized under the current state, and then controls the pressure between the sweeping blades and the conveyor belt to always be within the set range, thereby ensuring that the sweeping blades and the conveyor belt are always in close contact, so that the sweeping blades and the conveyor belt always maintain a constant pressure, extending the service life of the sweeping blades and the conveyor belt. This intelligent sweeper has an automatic compensation function. When the blades of the intelligent sweeping device are worn excessively, an alarm signal can be generated to remind replacement. It can also realize the automatic compensation function according to the wear degree of the sweeping blades.

[0019] (2) When a certain cleaning blade wears out, the rack pushes the metal slide to slide on the resistor, thereby reducing the resistance value and increasing the repulsive force of the electromagnet on the repulsion block accordingly, thereby automatically compensating for the pressure missing when the cleaning blade wears out, and realizing the automatic compensation function of a single cleaning blade.

[0020] (3) When the resistance value of the resistance sensor detected by the processing module exceeds the preset range, the processing module will also issue an alarm accordingly, effectively preventing the conveyor belt from being damaged due to excessive wear of a single cleaning blade.

[0021] (4) When a certain cleaning blade is worn out, the rotating rod can drive the control rod to rotate through the transmission belt. When the control rod rotates to a predetermined angle, the reminder layer will lose its magnetic constraint. Therefore, the reminder layer will be pushed by the compression spring and will fit into the reminder window, thereby changing the color of the reminder window. This allows the staff in the factory to replace the worn individual cleaning blade in time by looking at the reminder window.

[0022] (5) The reminder window is set to a frosted state, so when the reminder layer is not attached to the reminder window, it will automatically cover the reminder layer, effectively avoiding accidental triggering. Attached Figure Description

[0035] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0036] Example 1:

[0037] Please see Figure 1-3This application discloses an intelligent control system for belt sweeping based on remote operation and maintenance, including a frame, a roller 1 mounted on the frame, sweeping blades 3 for cleaning the conveyor belt on the roller 1, and a sweeping system for controlling the operation of the sweeping blades 3. The sweeping blades 3 are composed of multiple blade assemblies. The sweeping system includes a processing module 6 and a cloud module. The cloud module is connected to the processing module 6 via a 4G module and is used to obtain wear data information of the sweeping blades 3 through the processing module 6. One end of the sweeping blades 3 is provided with an actuator 5 electrically connected to the processing module 6, and the output end of the actuator 5 is equipped with a torsion sensor electrically connected to the processing module 6, which is used to obtain the torque of the actuator 5 and transmit the torque information to the processing module 6. The actuator 5 is fixed to the frame, and the transmission end of the actuator 5 is horizontally corresponding to a rod 2. One end of the rod 2 is connected to the actuator 5 via a coupling 4. An angle sensor electrically connected to the processing module 6 is installed inside the actuator 5. In use, firstly, the actuator 5 drives the rod 2 to rotate via the coupling 4. The rod 2 then causes the top cleaning blade 3 to come into close contact with the conveyor belt on the roller 1, achieving the cleaning effect. The torque sensor detects the output torque of the actuator 5, which is proportional to the pressure of the cleaning blade 3. The processing module 6 then obtains the pressure value of the cleaning blade 3 and compares it with a preset pressure range. The processing module 6 automatically determines whether the cleaning blade 3 should be pressurized or depressurized under the current condition. Subsequently, the processing module 6 drives the actuator 5 to perform the corresponding operation, thereby controlling the pressure between the cleaning blade 3 and the conveyor belt to always be within the set range, thus ensuring that the cleaning blade 3 and the conveyor belt are always in close contact, effectively guaranteeing the cleaning effect. The processing module 6 uses a PLC controller.

[0038] Please see Figure 1 When the cleaning system is in use, the processing module 6 interconnects with the cloud module via the 4G module. The cloud module includes a mobile terminal and a PC terminal. When the torque sensor detects excessive wear of the cleaning blade 3, the processing module 6 transmits the alarm signal to the cloud module. Therefore, both the mobile phone and the PC terminal can display the alarm status when connected to the network, truly achieving "unattended operation" and enabling remote operation and maintenance. The angle sensor inside the actuator 5 can detect the degree of blade wear and issue an alarm signal. The alarm can be pushed to the mobile phone via WeChat and data parameters can be modified remotely, greatly facilitating on-site debugging. Furthermore, it can be connected to the control room console via the 4G module. The control console can realize common interface display and common interface operation, including device start / stop, blade adhesion force display, blade adhesion force adjustment, blade wear status display, blade rotation angle display, wear limit alarm, and fault alarm.

[0039] It should be noted that the cleaning blade 3 is made of ultra-high molecular weight polyurethane material with a molecular weight of not less than 10 million, which has the functions of high wear resistance and low friction coefficient. The torque sensor adopts a dual-flange static torque sensor, and the actuator adopts a valve electric actuator, which does not require manual operation and increases the safety factor.

[0040] Example 2:

[0041] Please see Figure 4-7 Compared to Embodiment 1, Embodiment 2 of this application adds a metal slider 10 to realize the detection and automatic pressure compensation of a single cleaning blade 3. The blade assembly includes multiple rotating rods 18 arranged at intervals and rotatably connected to the rod body 2. A detachable cleaning blade 3 is installed on the top of the rotating rod 18, and torsion springs are sleeved at both ends of the rotating rod 18. An upper gear 7 is fixed to one end of the rotating rod 18, a lower gear 8 meshes with the bottom of the upper gear 7, and a rack 9 meshes with the bottom of the lower gear 8. The rack 9 is slidably connected to the rod body 2. A metal slider 10 is fixed to one end of the rack 9, and a resistor is provided below the metal slider 10. The metal slider 10 is slidably connected to the resistor. A repulsion block 12 is fixed to the bottom of the rotating rod 18, and an electromagnet 11 corresponding to the repulsion block 12 is fixed to the inner wall of the rod body 2. The electromagnet 11 and the repulsion block 12 have the same magnetism. The resistor is connected to the electromagnet 11 through a wire to control the magnetic force of the electromagnet 11. A resistance sensor is installed at the output end of the resistor, and the resistance sensor is electrically connected to the processing module 6.

[0042] Secondly, the torsion spring provides stable pressure to the cleaning blades 3 on the rotating rod 18, effectively maintaining the cleaning effect of the cleaning blades 3. During use, the cleaning blades 3 may wear unevenly, causing some blades 3 to wear too quickly. Therefore, the torque sensor cannot compensate for the pressure of the small number of excessively worn cleaning blades 3. Thus, when a cleaning blade 3 wears, it will move further under the action of the torsion spring to fit against the conveyor belt. The cleaning blade 3 drives the rack 9 to move through the upper gear 7 and the lower gear 8. The diameter of the upper gear 7 is larger than that of the lower gear 8, so the rack 9 moves a greater distance, causing the rack 9 to push the metal slide 10 to slide on the resistor, thereby reducing the resistance value. This causes the repulsive force of the electromagnet 11 on the repulsion block 12 to increase accordingly, thus automatically compensating for the pressure loss when the cleaning blade 3 wears. This can realize the automatic pressure compensation function for a single cleaning blade 3.

[0043] The resistor is a sliding resistor. The wear level of a single cleaning blade 3 can be detected by the resistance sensor. When the resistance value detected by the processing module 6 exceeds the preset range, the processing module 6 will also issue an alarm accordingly, effectively preventing the conveyor belt from being damaged due to the excessive wear of a single cleaning blade 3.

[0044] Example 3:

[0045] Please see Figure 7-10 An alarm component is installed at the end of the rotating rod 18 away from the upper gear 7. The alarm component includes a control rod 13. The control rod 13 and the rotating rod 18 are connected by a transmission belt 16. A first magnet is installed at the end of the control rod 13 away from the rotating rod 18. Multiple reminder layers 14 are slidably connected inside the rod body 2, and the reminder layers 14 are horizontally corresponding to the control rod 13. Magnetic particles opposite to the first magnet are fixed on the side of the reminder layer 14 facing the control rod 13. The reminder layer 14 and the rod body 2 are connected by a compression spring. Multiple reminder windows 15 corresponding to the reminder layers 14 are fixed on the outside of the rod body 2, and the reminder windows 15 are made of frosted material.

[0046] Finally, when a cleaning blade 3 is worn excessively, the rotating rod 18 can drive the control rod 13 to rotate via the transmission belt 16. When the control rod 13 rotates to a predetermined angle, the reminder layer 14 will lose its magnetic constraint. Therefore, the reminder layer 14 will be pushed by the compression spring to fit against the reminder window 15, thereby changing the color of the reminder window 15. This allows the staff in the factory to replace the worn individual cleaning blade 3 in time by looking at the reminder window 15. The reminder window 15 is frosted, so when the reminder layer 14 is not fitted against the reminder window 15, it will automatically cover the reminder layer 14.

[0047] The above are merely preferred embodiments of this application, but the scope of protection of this application 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 application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
