Description

Technical Field

[0001] The present invention belongs to the technical field of scraper conveyors and relates to an intelligent monitoring device for scraper conveyors. Background Art

[0002] As an important continuous conveying device, the scraper conveyor plays a key role in many industries such as coal, metallurgy, chemical industry, and building materials. Its structure mainly consists of components such as a driving device, a chain, a scraper, a frame, and a hopper. Through the reciprocating movement of the driving device to drive the chain and the scraper on the frame, the continuous conveying of materials from the feeding end to the discharging end is realized. Due to its advantages such as simple structure, large conveying capacity, stable operation, and convenient maintenance, the scraper conveyor is widely used in various conveying scenarios of bulk materials.

[0003] However, in practical applications, the scraper conveyor also exposes a series of problems and deficiencies. First of all, during the operation of the scraper conveyor, due to the influence of various factors such as materials and the environment on components such as the chain and the scraper, faults such as chain skipping, chain breaking, and foreign object jamming of the chain are likely to occur. This not only affects the normal conveying of materials but also may cause shutdowns or even safety accidents. Secondly, key components of the scraper conveyor such as the chain and the scraper are prone to wear or deformation under long-term friction and impact, resulting in a decrease in conveying efficiency or equipment failure and increasing the maintenance cost. Moreover, the lubrication system of the scraper conveyor is crucial for ensuring the normal operation of the equipment. However, in a harsh working environment, the lubricating oil is prone to dry up or become contaminated, affecting the lubrication effect and thus affecting the service life and performance of the equipment.

[0004] In addition, the operating state of the scraper conveyor has a direct impact on the quality and efficiency of the production process. However, due to the fact that the scraper conveyor is usually in a sealed or high-temperature environment and its internal structure is complex, it makes direct observation and detection difficult. Traditional monitoring methods often rely on regular manual inspections. This method not only consumes manpower and material resources but also is difficult to discover and handle potential problems in a timely manner, affecting production efficiency and safety.

[0005] In view of the above problems, most of the existing intelligent monitoring systems for the operating state of scraper conveyors monitor and diagnose based on a single signal source (such as visual signals, vibration signals, sound signals, etc.). Although these methods can reflect the operating state of the scraper conveyor to a certain extent, they each have limitations, are easily affected by the environment, and cannot comprehensively and accurately reflect the actual operating conditions of the scraper conveyor. At the same time, these systems usually require the installation of a large number of sensors and collectors, increasing the complexity and cost of the system and being not conducive to popularization and application. Summary of the Invention

[0006] The object of the present invention is to solve the technical problems in the prior art that most of the existing intelligent monitoring systems for the operating status of scraper conveyors monitor and diagnose based on a single signal source, are easily affected by environmental interference, cannot comprehensively and accurately reflect the actual operating conditions of the scraper conveyor, and installing a large number of sensors and collectors increases the complexity and cost of the system, which is not conducive to popularization and application, and provides an intelligent monitoring device for a scraper conveyor.

[0007] To achieve the above object, the present invention adopts the following technical solutions: The present invention discloses an intelligent monitoring device for a scraper conveyor, including: A bracket, on which a touch rod and an adjusting plate are respectively arranged. The touch rod is arranged in the touch area and is connected to the bracket through a semi-circular clamping plate. The adjusting plate is connected to the bracket through a bearing; one end of the adjusting plate located in the touch area is in contact with a thimble passing through a connecting column, and the connecting column is connected to the semi-circular clamping plate; a groove is provided at the top end of the adjusting plate located in the monitoring area, and a magnet is provided on the groove; the magnet is arranged close to a Hall proximity switch.

[0008] Preferably, the bracket includes a top bracket, a middle bracket, a bottom bracket and a connecting bracket. The top bracket, the middle bracket and the bottom bracket are horizontally arranged; the connecting bracket is vertically and fixedly connected to the top bracket, the middle bracket and the bottom bracket in sequence. The connecting bracket divides the intelligent monitoring device for the scraper conveyor into a touch area and a monitoring area; a bearing is provided at the lower part of the connecting bracket located in the middle bracket; a Hall proximity switch is provided at the position of the top bracket located in the monitoring area; the semi-circular clamping plate is fixed on the middle bracket.

[0009] Preferably, the adjusting plate is connected to one end of a spring through a moving end spring fixer, and the other end of the spring is connected to the connecting bracket through a fixed end spring fixer.

[0010] Preferably, buckles are respectively connected to both ends of the top bracket, the middle bracket and the bottom bracket, and a buckle sealing strip is arranged between the buckle and the bracket.

[0011] Preferably, a bottom plate is connected to the bottom bracket, and a disassembly sealing strip is arranged between the bottom plate and the bottom bracket.

[0012] Preferably, a notch is provided at the position of the adjusting plate close to the bottom in the monitoring area, and a bolt is arranged at the notch.

[0013] Preferably, the notch is in an arc-shaped structure.

[0014] Preferably, a magnet limiting thin sheet is arranged between the magnet and the groove of the adjusting plate.

[0015] Preferably, the connecting column is sleeved and connected with the adjusting plate.

[0016] Preferably, the connecting column is fixedly connected with the adjusting plate along the axial direction of the adjusting plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention discloses an intelligent monitoring device for a scraper conveyor. By the combined use of a Hall proximity switch and a magnet in the device, the position change of the adjusting plate can be monitored in real time. When the material or component on the scraper conveyor touches the trigger rod, the adjusting plate is displaced through mechanical transmission, and then drives the magnet to approach or move away from the Hall proximity switch, realizing non-contact signal triggering. This design not only improves the sensitivity and accuracy of monitoring, but also can send out early warning signals in case of abnormalities to prevent equipment failures or safety accidents. The adjusting plate is connected to the connecting bracket through a bearing, and this design enables the adjusting plate to rotate or translate freely within a certain range, so as to adapt to the operating characteristics of the scraper conveyor under different working conditions. At the same time, by adjusting the positions of the semi-circular clamping plate and the connecting column, the interaction force between the trigger rod and the adjusting plate can be conveniently adjusted to ensure the stability and reliability of the monitoring device under different load conditions. The monitoring device adopts a modular design, and the top bracket, middle bracket, bottom bracket and connecting bracket are vertically fixedly connected to form a solid overall structure. This design not only makes the device structure compact and occupies a small space, but also facilitates installation and maintenance on the scraper conveyor. In addition, the connection between the components is simple and clear, reducing the installation difficulty and cost. By monitoring the operating state of the scraper conveyor in real time, potential problems can be discovered and processed in time, effectively avoiding equipment downtime for maintenance, thereby improving production efficiency and equipment utilization rate. At the same time, the application of the intelligent monitoring device also reduces the frequency and intensity of manual inspections, reducing labor costs and maintenance costs.

[0018] Furthermore, the introduction of the spring provides an elastic buffering effect for the adjusting plate. When the material or component on the scraper conveyor touches the trigger rod, the spring can absorb part of the impact force and slow down the sudden displacement of the adjusting plate, thereby protecting the precision components inside the monitoring device from damage. This design improves the stability and reliability of the monitoring device under complex working conditions. The elastic force of the spring enables the adjusting plate to quickly return to its initial position after being touched, preparing for the next monitoring. At the same time, the pre-tightening force of the spring can be adjusted according to actual needs to optimize the sensitivity of the monitoring device. This design enables the monitoring device to more accurately capture the changes in the operating state of the scraper conveyor and improve the response speed.

[0019] Furthermore, the design of the arc-shaped notch allows the pin to move freely within a certain angular range in the notch. This design enables the adjusting plate to more flexibly adjust its position when receiving the force transmitted by the trigger rod, so as to adapt to the touch forces in different directions. Therefore, the monitoring device can more accurately respond to various operating state changes of the scraper conveyor, improving the accuracy and reliability of monitoring.

[0029] The following further describes the present invention in detail with reference to the drawings: See Figure 1 、 Figure 2 and 3 , an intelligent monitoring device for the operating state of a scraper conveyor, comprising: A bracket 1 for fixing the main structure of the intelligent monitoring device of the scraper conveyor. The bracket 1 is provided with threaded holes, and the buckle plate 2, the buckle plate seal strip 3 and the bracket 1 are connected by the buckle plate bolts 4. The buckle plate 2 is respectively connected to both ends of the top bracket, the middle bracket and the bottom bracket to ensure airtightness and easy disassembly and assembly; the bracket 1 includes a top bracket, a middle bracket, a bottom bracket and a connecting bracket. The top bracket, the middle bracket and the bottom bracket are horizontally arranged; the connecting bracket is vertically and fixedly connected to the top bracket, the middle bracket and the bottom bracket in sequence. The connecting bracket divides the intelligent monitoring device of the scraper conveyor into a touch area and a monitoring area; a bearing 20 is provided at the lower part of the middle bracket of the connecting bracket; the bearing 20 reduces the friction between the adjusting plate 14 and the bracket 1, makes the adjusting plate 14 rotate more smoothly, and reduces energy consumption; a Hall proximity switch 28 is provided at the position of the top bracket in the monitoring area.

[0030] The dismountable sealing strip 5 is used to ensure the airtightness of the connection between the bottom bracket of the bracket 1 and the bottom plate 6; the bottom plate 6 and the bottom plate sealing strip 8 are connected by bottom plate bolts 7; the bracket 1, the dismountable sealing strip 5 and the bottom plate 6 are connected by countersunk head screws 9.

[0031] The trigger rod 10 is used to obtain the motion state of the scraper, and its position is fixed by the limit of two semi-circular clamping plates 11, and the two semi-circular clamping plates 11 are fixed by clamping plate flange bolts 12 and clamping plate flange nuts 13.

[0032] The adjusting plate 14 is a part connecting the trigger area and the monitoring area of the device, used to transmit the force of the trigger rod 10; the adjusting plate 14 is connected to the connecting bracket through a bearing 20; one end of the adjusting plate 14 located in the trigger area is in contact with a thimble 21 passing through a connecting column 22, and the connecting column 22 is connected to the semi-circular clamping plate 11; a groove is provided at the top end of the adjusting plate 14 located in the monitoring area, and a magnet 25 is provided on the groove; the magnet 25 is arranged close to the Hall proximity switch 28. The moving end spring retainer 15 avoids its rotation through its own shape constraint, and is fixed to the adjusting plate 14 by an M6 thin nut 16 and an M6 flat washer 17, and jointly limits the position of the spring 31 with the fixed end spring retainer 18; the fixed end spring retainer 18 avoids its rotation through its own shape constraint, and is fixed to the connecting bracket of the bracket 1 by an M6 thin nut 16 and an M6 flat washer 17.

[0033] The pin 19 passes through an arc-shaped notch reserved on the adjusting plate 14 to limit the rotation range of the adjusting plate 14; the connecting column 22 is connected to the semi-circular clamping plate 11 by a clamping plate flange bolt 12 and a clamping plate flange nut 13, and then transfers the motion of the trigger plate to the adjusting plate 14 through the shape constraint and the thimble 21; the connecting column 22 is sleeved on the shaft end of the adjusting plate 14, and the connecting column 22 is axially fixed to the adjusting plate 14 by a round nut 23 and a lock washer 24. The combination of the round nut 23 and the lock washer 24 jointly ensures the relative position between the connecting column 22 and the adjusting plate 14, preventing the adjusting plate 14 from moving or retracting during connection, thereby providing a reliable reference point for the operation of the device.

[0034] The magnet 25 provides a magnetic field for the Hall proximity switch 28; the magnet limiting thin sheet 26 restricts the magnet 25 at the groove at the upper end of the adjusting plate 14 by an M4 bolt 27; the Hall proximity switch 28 is connected to the bracket 1 through its own thread, and its up and down movement is avoided by an M12 thin nut 29 and an M12 flat washer 30; the spring 30 is a part providing tensile force, enabling the adjusting plate to quickly return to its original state, and its position is jointly determined by the moving end spring retainer 15 and the fixed end spring retainer 18.

[0035] During installation, the top bracket, middle bracket, and bottom bracket are vertically fixed through the connecting bracket to form an integral frame structure. The bearing 20 is installed at the lower part of the connecting bracket to ensure that the adjusting plate 14 can rotate freely around the bearing. The bottom bracket is connected to the bottom plate 6 through the disassembly seal strip 5 and fixed with the countersunk head screw 9 to ensure the sealing performance. The bottom plate 6 and the bottom plate seal strip 8 are fastened through the bottom plate bolt 7 to form an airtight base. The trigger rod 10 is placed between the two semi-circular clamping plates 11 and fixed through the clamping plate flange bolt 12 and the clamping plate flange nut 13 to ensure the axial limit of the trigger rod and its offset along with the movement of the scraper. One end of the adjusting plate 14 is connected to the connecting bracket through the bearing 20, and an arc-shaped notch is opened at the other end and the pin 19 is inserted to limit its rotation range; the connecting column 22 is sleeved on the shaft end of the adjusting plate 14 and axially fixed through the round nut 23 and the locking washer 24 to ensure that the connecting column and the thimble 21 synchronously transmit the displacement of the trigger rod 10. The magnet 25 is embedded in the groove at the top of the adjusting plate 14 and fixed by the magnet limit thin sheet 26 and the M4 bolt 27. The Hall proximity switch 28 is installed through the threaded hole of the bracket 1 and locked with the M12 thin nut 29 and the flat washer 30. Both ends of the spring 31 are fixed to the adjusting plate 14 and the connecting bracket through the moving end fixator 15 (M6 thin nut 16 + flat washer 17) and the fixed end fixator 18 respectively to provide a pulling force to reset the adjusting plate.

[0036] The working process / working principle of the intelligent monitoring device for the operating state of the scraper of the present invention is as follows: When the scraper conveyor is in operation, the scraper interacts with the material, and its motion state will be reflected in the trigger rod 10 in real time. The trigger rod 10 is ingeniously placed between two semi-circular clamping plates 11. Through the tight fixation of the clamping plate flange bolts 12 and the clamping plate flange nuts 13, it not only ensures the stable axial limit of the trigger rod but also allows it to deflect with the movement of the scraper in the plane perpendicular to the axial direction. Once the scraper shows conditions such as tilt, uneven height, or abnormal position, the trigger rod 10 will accordingly displace, and this displacement is a direct physical manifestation of the change in the scraper's motion state. When the trigger rod 10 deflects, the displacement of the trigger rod 10 is transmitted to the adjusting plate 14 through the connecting column 22. The connecting column 22 is sleeved on the shaft end of the adjusting plate 14 and is axially fixed by a round nut 23 and a locking washer 24, ensuring the relative position stability between the connecting column 22 and the adjusting plate 14, so that the displacement of the trigger rod 10 can be accurately transmitted to the adjusting plate 14. The adjusting plate 14 is a key part connecting the trigger area and the monitoring area. One end of it contacts the thimble 21 passing through the connecting column 22, and the other end is located in the monitoring area and is provided with a groove with a special structure. When the trigger rod 10 displaces, the thimble 21 will transmit this force to the adjusting plate 14, causing the adjusting plate 14 to rotate around the bearing 20. The setting of the bearing 20 greatly reduces the friction between the adjusting plate 14 and the bracket 1, making the rotation of the adjusting plate 14 smoother, reducing energy consumption, and at the same time improving the accuracy and stability of force transmission. During the rotation of the adjusting plate 14, the magnet 25 arranged on the top groove of it will also move accordingly, resulting in a change in the magnetic field position around the magnet 25. The magnet 25 is firmly restricted at the groove at the upper end of the adjusting plate 14 through the magnet limit thin sheet 26 and the M4 bolt 27, ensuring the position stability of the magnet 25 during the rotation of the adjusting plate 14. The Hall proximity switch 28 is installed at the position of the top bracket of the bracket 1 located in the monitoring area. It is tightly connected to the bracket 1 through its own thread and is prevented from moving up and down by the M12 thin nut 29 and the M12 flat washer 30, ensuring the position accuracy of the Hall proximity switch 28 during operation. When the magnetic field position of the magnet 25 changes, the Hall proximity switch 28 will sensitively sense this change and output a corresponding electrical signal. Since the output signal of the Hall proximity switch 28 is closely related to the magnetic field strength and position, even a small displacement of the magnet 25 will cause a significant change in the output signal of the Hall proximity switch 28.

[0037] This signal change is utilized to measure the time when the scraper reaches a specific position. By comparing the time difference between the two ends of the scraper rod of the scraper conveyor, the current state of the scraper can be obtained. If the time difference is large, it indicates that the scraper may be tilted. When the trigger rod 10 returns to its original position, the output signal of the Hall proximity switch 28 changes again, and the time difference can also be measured to determine whether the scraper is uneven.

[0038] The present invention monitors the rotation angle of the adjusting plate 14 in real time through the non-contact magnetic field induction between the Hall proximity switch 28 and the magnet 25, and indirectly reflects the scraper offset. The magnetic induction monitoring greatly reduces the monitoring error and at the same time avoids the hysteresis problem caused by mechanical wear of traditional contact sensors; the bracket 1 is assembled in a hierarchical modular manner (top / middle / bottom brackets + connecting brackets), and the quick disassembly and assembly are realized by cooperating with the buckle sealing strip 3 and the disassembly sealing strip 5. Key components (such as Hall switches and springs 31) are independently replaceable, reducing the troubleshooting time. The double-sealing structure (buckle sealing strip 3 + disassembly sealing strip 5) effectively blocks water vapor and coal dust.

[0039] The intelligent monitoring device of the present invention can not only efficiently and accurately monitor the operating state of the scraper conveyor, but also has obvious technical and economic advantages in terms of assembly and maintenance. Through precise signal capture and analysis, the system can monitor the state of the scraper conveyor in real time and provide accurate analysis data, which helps to timely discover and solve problems, and improve production efficiency and equipment reliability.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
