The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
An operation detection system of a conveying apparatus according to an embodiment of the present invention is described below with reference to fig. 1 to 3.
The present invention provides an operation detection system of a conveying apparatus, as shown in fig. 1, 2 and 3, comprising: conveyor 1, distance measuring sensor 2, current sensor 3, speed sensor 4 and controller 5.
In this embodiment, the conveyor 1 is a buried scraper conveyor, and the conveyor 1 includes: a conveying box 11, a transmission part, a rotating shaft 13, a conveying assembly and a transmission motor 12. The conveying box 11 is the shell of the whole conveyor 1, a hollow structure is adopted, bearing seats 14 are arranged at the front end and the rear end of the conveying box 11, two rotating shafts 13 are arranged on the bearing seats 14 at the front end and the rear end of the conveying box 11 respectively, rotating teeth are arranged on the two rotating shafts 13 simultaneously, a transmission piece is a chain, the transmission piece is meshed with the rotating teeth, and the rotating shafts 13 at the two ends are connected through transmission piece transmission. The conveying component is a scraper, is connected with the transmission piece, is in transmission connection with a rotating shaft 13, and is used for pushing materials in cooperation with chain rotation.
When the conveyor 1 starts to convey, the transmission motor 12 drives the transmission part and the conveying component to move, the pressure of the transmission part and the conveying component in the moving direction and the action of the weight of the materials generate internal friction force between the materials, the friction force ensures the stable state between the material layers, and the external friction resistance generated by the movement of the materials in the conveying box 11 is overcome, so that the materials form an integral material flow to be conveyed.
The distance measuring sensor 2 is arranged on one side of the conveying box 11 and is generally arranged at the top of the conveying box 11, and the distance measuring sensor 2 is used for detecting the height of materials in the conveying box 11. In this embodiment, the ranging sensor 2 adopts a laser ranging sensor, and the laser ranging sensor uses a laser diode to emit laser pulses aiming at the material due to a series of reasons such as large dust, high temperature, interference of movement of upper and lower scrapers and the like in the conveying box 11. The laser light is scattered in all directions after being reflected by the material. Part of the scattered light returns to the receiver of the laser ranging sensor, is received by the optical system and imaged onto the photodiode. The photodiode detects extremely weak light signals. The time elapsed from the emission of the light pulse to the return being received is recorded and processed, and the material height can be determined.
The current sensor 3 is electrically connected to the drive motor 12, and the current sensor 3 can detect a direct current in a high-speed transient state, thereby being capable of detecting a motor current of the current sensor 3.
Wherein the speed sensor 4 is arranged on one of the rotation shafts 13, the speed sensor 4 may employ an encoder. An encoder is a device that compiles, converts, or communicates, transmits, and stores signals or data into a signal form. Mainly into a series of digital pulse signals. The encoder is used for detecting the running speed of the scraper chain and detecting a broken chain signal.
In this embodiment, the transmission motor 12 drives the left rotation shaft 13 to rotate, the transmission member drives the right rotation shaft 13 to rotate, and since the speed sensor 4 is disposed on the right rotation shaft 13, the linear speed of transportation can be detected by the rotation of the right rotation shaft 13, and the rotation speed of the transmission motor 12 can be determined according to the conversion relationship.
The controller 5 may employ a programmable logic controller (Programmable Logic Controller, abbreviated as PLC), which is a digital operation electronic system designed specifically for automation control in an industrial environment. The programmable controller is formed by modularly combining an internal CPU, an instruction and data memory, an input and output unit, a power module, a digital analog unit and the like, and controls various types of mechanical equipment or production processes through digital or analog input and output. The controller 5 is electrically connected with the speed sensor 4, the driving motor 12, the distance measuring sensor 2 and the current sensor 3, so that the controller 5 can acquire a material height signal detected by the distance measuring sensor 2, a motor current signal detected by the current sensor 3, a linear speed signal detected by the speed sensor 4 and a control signal sent by the driving motor 12.
In the normal operation of the operation detection system of the conveying device, the controller 5 can be used for inputting the preset conveying amount, so that the conveyor 1 works according to the preset conveying amount, and meanwhile, the controller 5 can determine the conveying amount in unit time according to the height and the linear speed of the material, namely, the conveying amount is measured.
Before determining the transport capacity, the horizontal coordinate y and the height coordinate x of the distance measuring sensor 2 are defined, the transport box 11 without the material is subjected to multi-point measurement, and a height model of the transport box 11 without any material is constructed (at this time, the occupied volume of the structures such as a transmission part, a rotating shaft 13, a transport assembly and the like can be ignored).
y 2 ＝A 1 x+B 1
Wherein A is 1 、B 1 Is a model constant of the transport box 11.
Then, the material-carrying conveying box 11 is subjected to multi-point measurement, and a height model of the material can be constructed according to the height of the material.
y 2 ＝A 2 x+B 2
Wherein A is 2 、B 2 Is a model constant of the material.
And the height model of the conveying box 11 and the height model of the material are simplified and calculated through the height model of the conveying box 11 and the height model of the material, so that a mathematical function of the height and the sectional area of the material is obtained.
Wherein S1 is the sectional area of the material, f 1 (x) To simplify the function of the transport box 11 in two intervals after calculation, x 1 Is the height of the highest point of the material, x 2 Is the lowest point height of the transfer box 11.
In determining the measured transportation amount, the material height may be measured based on the distance measuring sensor 2, and the sectional area of the material may be determined according to the material height, so that the measured transportation amount may be determined using the linear velocity.
Since the measured traffic at this time is based on the material height and speed, there is a portion of material remaining during the transport of the conveyor 1, and the size of the remaining amount directly affects the measured traffic obtained by the measurement. In order to increase the accuracy, after determining the measured traffic volume, the controller 5 performs a comparative analysis according to the motor current and a preset current (standard current), thereby facilitating correction of the measured traffic volume by the comparative analysis result to determine the actual traffic volume.
For example, when the motor current is larger than the preset current, it is indicated that the load driven by the transmission motor 12 is larger than the normal value, and it is indicated that the remaining amount in the conveyance case 11 is larger, at this time, the generation of the first correction parameter may be controlled so as to determine the actual traffic = measured traffic-first correction parameter at this time.
When the motor current is smaller than the preset current, it means that the load driven by the driving motor 12 is smaller than the normal value, and that the remaining amount in the conveying box 11 is smaller, and the second correction parameter can be controlled to be generated at this time, so that the actual conveying amount=the measured conveying amount+the second correction parameter at this time is determined.
After the actual traffic volume is determined, the rotation speed of the transmission motor 12 is adjusted based on comparison between the preset traffic volume inputted in advance by the controller 5 and the actual traffic volume. For example, if the preset traffic is greater than the actual traffic, the rotation speed of the transmission motor 12 is increased. If the preset traffic is smaller than the actual traffic, the rotation speed of the transmission motor 12 is reduced.

In order to be able to find the breaking state and the tightness of the transmission element in time, in a specific embodiment, as shown in fig. 4 to 7, the conveyor 1 is a scraper, the transmission element is a chain 20 arranged in a ring shape, and the operation detection system of the conveying device further comprises: the device comprises a support 21, a connecting rod 22, a first limiting piece 23, a second limiting piece 24 and a proximity switch 25.
Wherein the supporting member 21 is rotatably disposed in the conveying box 11, the supporting member 21 is disposed at the bottom of the chain 20, and the link 22 is connected to the supporting member 21, and the link 22 is disposed outside the conveying box 11, so that the link 22 rotates synchronously when the supporting member 21 rotates.

As shown in fig. 6 and 7, when the chain 20 breaks or the tightness degree is low, the chain 20 presses down the supporting member 21, the supporting member 21 is adjusted to the first state, the supporting member 21 abuts against the chain 20, the supporting member 21 abuts against the second limiting member 24, and the connecting rod 22 rotates to abut against the proximity switch 25, so that a user can judge that the chain 20 breaks or the tightness degree is low according to the state of the proximity switch 25.

In order to find the suspension degree of the transmission member in time, in another specific embodiment, as shown in fig. 8, 9, 10 and 11, the conveyor 1 is a scraper, the transmission member is a chain 20 which is annularly arranged, and the operation detection system of the conveying device further includes: a wheel 26, a shield 27 and a rotation detection sensor 28. The rotating wheel 26 is rotatably arranged in the conveying box 11 through a rotating shaft, the rotating wheel 26 is positioned between the chains 20 which are annularly arranged, namely, the rotating wheel 26 is positioned between an upper chain and a lower chain, the rotating wheel 26 and the chains 20 are arranged at intervals, the protective cover 27 is arranged on at least one side of the rotating wheel 26, the rotation detection sensor 28 is electrically connected with the controller, and the rotation detection sensor 28 is used for detecting the rotation condition of the rotating wheel 26.

When the bottom materials are accumulated more, as shown in fig. 9, the rotating wheel 26 contacts with the lower chain under the accumulation action of the materials, the lower chain drives the rotating wheel 26 to rotate, the rotation detection sensor 28 can detect the rotation of the rotating wheel 26, when the rotating wheel 26 rotates for a certain time, the chain 20 can be determined to be in an abnormal state, the bottom materials are accumulated more, and the user needs to adjust the chain 20. Therefore, a user can control the machine halt by using the controller when the material blockage begins to occur, so that accidents caused by a large amount of material blockage can be avoided, the situation that a large amount of labor is required to be input for repairing during the restoration of the machine halt of important equipment is avoided, and great economic loss is avoided.
In one embodiment, as shown in fig. 12, the delivery assembly includes: a scraper 29, a scraper shaft and a position switch. The scraper 29 is connected to the transmission member via a scraper shaft, i.e. the scraper 29 is rotatably connected to the chain 20, and the position switch is used to limit the angle of the shaft relative to the transmission member. The position switch is electrically connected to the controller 5, and the controller 5 is configured to control the position switch in accordance with the motor current and the linear velocity to switch the scraper 29 between a first position perpendicular to the transport tank 11 and a second position parallel to the transport tank 11.
Specifically, it is assumed that the scraper 29 is in the first position perpendicular to the conveyance case 11 in the initial state. When the linear velocity of the driving motor 12 is controlled to be the preset linear velocity, if the controller 5 detects that the motor current is larger than the corresponding current when the preset linear velocity is detected by the current sensor 3, the controller 5 uses the position switch to control the scraper 29 to rotate a certain angle (less than or equal to 90 degrees) towards the second position according to the current magnitude, wherein the fact that the load of the driving motor 12 is larger at this time is indicated. When the controller 5 detects that the motor current is smaller than the corresponding current when the current sensor 3 detects that the load of the transmission motor 12 is smaller at the moment, the controller 5 controls the scraper 29 to rotate a certain angle towards the first position by utilizing the position switch according to the current magnitude. Thus, the controller 5 can ensure that the current of the transmission motor 12 is in a certain range, and ensure the stable operation of the transmission motor 12.
According to actual needs, when the driving motor 12 is just started, if the current detected by the controller 5 through the current sensor 3 is larger (the current corresponding to the preset linear speed is exceeded), which indicates that the load is larger at this time, the driving motor 12 is in a full-load starting state, and at this time, the scraper 29 can be controlled to rotate by a certain angle towards the second position. When the driving motor 12 is just started, if the current detected by the controller 5 through the current sensor 3 is smaller (lower than the current corresponding to the preset linear speed), which indicates that the load is smaller at this time, the driving motor 12 is in the half-load starting state, and the scraper 29 can be controlled to rotate by a certain angle towards the first position.
And the operator can set the variable frequency starting of the transmission motor 12, and limit the current of the transmission motor 12 to be always smaller than the rated current, so that the transmission motor 12 achieves corresponding torque in the slow running process, and gaps among transmissions are eliminated.
It should be noted that, in the actual use process, the chain 20 may be provided with a plurality of scrapers 29, each scraper 29 is connected to the chain 20 through a scraper shaft, and each scraper 29 is correspondingly provided with a position switch, so that each scraper 29 can be switched between a first position perpendicular to the conveying box 11 and a second position parallel to the conveying box 11.
To realize the joint control of a plurality of scrapers 29, the scrapers 29 at different positions can be controlled to rotate at different angles by position switches according to the different positions where the scrapers 29 are currently located, namely, the controller 5 runs to different positions through the scrapers 29. Specifically, it is assumed that the scraper 29 is in the first position perpendicular to the conveyance case 11 in the initial state. When the scraper 29 is moved near the feed opening, the scraper 29 can be controlled to rotate a first preset angle (less than 90 degrees) relative to the vertical position due to more material, and when the scraper 29 is moved to the discharge opening, the scraper 29 is controlled to rotate a second preset angle (less than 90 degrees) relative to the vertical position, which is less than the first preset angle, so that the scraper 29 is as perpendicular to the conveyor box 11 as possible, in order to guide out the material as much as possible.
Further, in order to facilitate the joint control of the plurality of scrapers 29, weighing sensors corresponding to the scrapers 29 one by one may be disposed at different positions of the conveying box 11, and when the weight changes, the angle of the scrapers 29 is correspondingly adjusted, and the movement direction angle of the scrapers 29 changes. When the weight measured by one of the load cells is relatively large, the corresponding scraper 29 can be controlled to rotate by a first preset angle (less than 90 degrees) relative to the vertical position, and when the weight measured by one of the load cells is relatively small, the corresponding scraper 29 can be controlled to rotate by a second preset angle (less than 90 degrees) relative to the vertical position, and the second preset angle is smaller than the first preset angle, so that the scrapers 29 at different positions have different rotation angles.
In a bulk inflammable and explosive material lifting system in industries such as coal chemical industry, petrochemical industry, graphite cathode, calcium carbide and the like, some materials are burnt and even exploded after oxygen content reaches a certain concentration due to low ignition point; some materials can deteriorate when encountering oxygen or water in the air, and normal production is seriously affected. Therefore, when a user orders the conveying equipment, higher requirements are put on the performances of sealing, explosion prevention, static prevention, temperature resistance, pressure resistance, continuous operation, conveying capacity, lifting height and the like of the equipment.
To solve the above-mentioned problems, in one embodiment, as shown in fig. 1 to 3, an oxygen probe and a sensor probe are further provided in the operation detection system of the transporting apparatus.
In this embodiment, the oxygen probe is fixed on the delivery box 11, and the oxygen probe extends into the delivery box 11 to monitor the oxygen concentration in the delivery box 11 in real time. The data is fed back to the controller 5 (DCS) in real time, and the explosion can be effectively prevented by using nitrogen to reduce the oxygen proportion due to the fact that the explosion is carried out on the premise that the oxygen is sufficiently concentrated when one of the necessary conditions is burnt. The minimum oxygen concentration for most combustible gases is about 10% and for most dust is 8%. And (3) inert treatment is carried out on the mixed gas in the bucket elevator shell by taking nitrogen as inert gas, so that the oxygen is reduced to a safe concentration. When the oxygen concentration reaches a preset dangerous threshold, the controller 5 controls an accident nitrogen charging port in the middle of the equipment to charge a large amount of nitrogen into the conveying box 11, simultaneously opens a top gas discharge valve, and discharges high-oxygen concentration gas so as to reduce the oxygen concentration in the equipment until the safety threshold is reached. Meanwhile, the oxygen content probe continuously monitors the oxygen concentration in the cavity, when the oxygen concentration is maintained below a safety threshold, the controller 5 controls the nitrogen charging port at the head and tail of the conveying box 11, stops charging nitrogen into the conveying box 11, and closes the gas discharge valve.
In this embodiment, the temperature and pressure of the head and tail cavities of the conveying box 11 are monitored by the sensor probe in real time, the temperature and pressure can be visually displayed on the sensor probe, meanwhile, the temperature and pressure values are fed back to the controller 5 in real time, when the temperature or the pressure exceeds a first-level preset threshold value, an alarm signal is sent, meanwhile, a large amount of nitrogen is filled into the cavities through an accident nitrogen filling port in the middle of the controller 5 control equipment, and a top gas discharge valve is opened, so that pressure relief and flame retardance are achieved, and temperature rise is prevented. If the above treatment does not reach the expected effect, the controller 5 controls the equipment to stop when the temperature exceeds the second-level preset threshold value, and the fire-fighting water interface is automatically opened to realize fire-fighting explosion prevention.
In summary, the operation detection system of the conveying equipment has the functions of remote start and stop, real-time monitoring, early warning in advance, remote diagnosis, intelligent repair and the like.
The present invention also provides a control method of an operation detection system of a conveying apparatus, as shown in fig. 13, and the operation detection system of the conveying apparatus is shown in fig. 1 to 12, which are not described herein, and the control method includes the following steps:
step S101: and acquiring the material height in the conveying box, the motor current of the transmission motor and the linear speed of transportation.
The controller 5 is electrically connected with the speed sensor 4, the driving motor 12, the distance measuring sensor 2 and the current sensor 3, so that the controller 5 can acquire a material height signal detected by the distance measuring sensor 2, a motor current signal detected by the current sensor 3, a linear speed signal detected by the speed sensor 4 and a control signal sent by the driving motor 12.
Step S102: and determining the measured conveying quantity according to the material height and the linear speed.
In the normal operation of the operation detection system of the conveying device, the controller 5 can be used for inputting the preset conveying amount, so that the conveyor 1 works according to the preset conveying amount, and meanwhile, the controller 5 can determine the conveying amount in unit time according to the height and the linear speed of the material, namely, the conveying amount is measured.
Before determining the transport capacity, the horizontal coordinate y and the height coordinate x of the distance measuring sensor 2 are defined, the transport box 11 without the material is subjected to multi-point measurement, and a height model of the transport box 11 without any material is constructed (at this time, the occupied volume of the structures such as a transmission part, a rotating shaft 13, a transport assembly and the like can be ignored).
y 2 ＝A 1 x＝B 1
Wherein A is 1 、B 1 Is a model constant of the transport box 11.
Then, the material-carrying conveying box 11 is subjected to multi-point measurement, and a height model of the material can be constructed according to the height of the material.
y 2 ＝A 2 x+B 2
Wherein A is 2 、B 2 Is a model constant of the material.
And the height model of the conveying box 11 and the height model of the material are simplified and calculated through the height model of the conveying box 11 and the height model of the material, so that a mathematical function of the height and the sectional area of the material is obtained.
Wherein S1 is the sectional area of the material, f 1 (x) To simplify the function of the transport box 11 in two intervals after calculation, x 1 Is the height of the highest point of the material, x 2 Is the lowest point height of the transfer box 11.
In determining the measured transportation amount, the material height may be measured based on the distance measuring sensor 2, and the sectional area of the material may be determined according to the material height, so that the measured transportation amount may be determined using the linear velocity.
Step S103: and correcting the traffic according to the motor current and the preset current, and determining the actual traffic.
Since the measured traffic at this time is based on the material height and speed, there is a portion of material remaining during the transport of the conveyor 1, and the size of the remaining amount directly affects the measured traffic obtained by the measurement. In order to increase the accuracy, after determining the measured traffic volume, the controller 5 performs a comparative analysis according to the motor current and a preset current (standard current), thereby facilitating correction of the measured traffic volume by the comparative analysis result to determine the actual traffic volume.
For example, when the motor current is larger than the preset current, it is indicated that the load driven by the transmission motor 12 is larger than the normal value, and it is indicated that the remaining amount in the conveyance case 11 is larger, at this time, the generation of the first correction parameter may be controlled so as to determine the actual traffic = measured traffic-first correction parameter at this time.
When the motor current is smaller than the preset current, it means that the load driven by the driving motor 12 is smaller than the normal value, and that the remaining amount in the conveying box 11 is smaller, and the second correction parameter can be controlled to be generated at this time, so that the actual conveying amount=the measured conveying amount+the second correction parameter at this time is determined.
Step S104: and adjusting the rotating speed of the transmission motor according to the actual transportation quantity and the preset transportation quantity.
After the actual traffic volume is determined, the rotation speed of the transmission motor 12 is adjusted based on comparison between the preset traffic volume inputted in advance by the controller 5 and the actual traffic volume. For example, if the preset traffic is greater than the actual traffic, the rotation speed of the transmission motor 12 is increased. If the preset traffic is smaller than the actual traffic, the rotation speed of the transmission motor 12 is reduced.
According to the control method of the operation detection system of the conveying equipment, provided by the invention, the distance measurement sensor 2 is arranged in the conveying box 11 of the conveyor 1 to detect the height of materials, meanwhile, the current sensor 3 is arranged on the transmission motor 12 of the conveyor 1, the speed sensor 4 is used for detecting the rotating shaft 13 to determine the linear speed, and the controller 5 is electrically connected with the speed sensor 4, the transmission motor 12, the distance measurement sensor 2 and the current sensor 3, so that the controller 5 can determine the measured transportation quantity according to the height of materials and the linear speed, and correct and determine the actual transportation quantity according to the motor current and the preset current, so that the rotating speed of the transmission motor is adjusted according to the actual transportation quantity and the preset transportation quantity. Therefore, on the premise of detecting the working state of the conveyor 1 in real time, accurate feeding of the conveyor is guaranteed, and stable operation of conveying equipment is guaranteed.
When the accurate feeding is not required, in the case of controlling the linear speed of the driving motor 12 to be the preset linear speed, if the controller 5 detects that the motor current is larger than the corresponding current when the preset linear speed is detected by the current sensor 3, the load of the driving motor 12 is larger at this time, and the controller 5 uses the position switch according to the current magnitude to control the scraper 29 to rotate a certain angle (less than or equal to 90 degrees) towards the second position. When the controller 5 detects that the motor current is smaller than the corresponding current when the current sensor 3 detects that the load of the transmission motor 12 is smaller at the moment, the controller 5 controls the scraper 29 to rotate a certain angle towards the first position by utilizing the position switch according to the current magnitude. Thus, the controller 5 can ensure that the current of the transmission motor 12 is in a certain range, and ensure the stable operation of the transmission motor 12.
