[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The automatic raw material conveying device used for steel structure processing is usually composed of conveyors, turning machines, transporters, etc. Its function is to transport various raw materials, semi-finished products, finished products, etc. required for the production line from one processing step to the next, thereby realizing automated production.

[0003] The raw material conveying device currently used in processing steel structures cannot ensure the conveying position of the raw materials for steel structure processing, which easily causes the placement and distribution position of the raw materials for steel structure processing on the conveyor belt to be biased to one side, causing the movement trajectory of the conveyor frame to deviate from the original direction, resulting in offset or vibration problems.

On both sides of the back of the conveying rack, an oil inlet pipe and an oil outlet pipe are respectively fixedly arranged, and one end of the oil inlet pipe and the oil outlet pipe are respectively communicated with the inside of the support rollers on both sides.

[0015] Preferably, the operation monitoring module is used to monitor and process the conveying parameters of each time point in each conveying period of the conveyor belt. The specific monitoring method is as follows:

[0016] The displacement sensor is used to obtain the offset distance of the conveyor belt at each time point in each conveying period, and the offset value of the conveyor belt at each time point in each conveying period is obtained.

[0017] The temperature sensor is used to obtain the conveying temperature of the conveyor belt at each time point in each conveying period, and the temperature value of the conveyor belt at each time point in each conveying period is obtained.

[0018] The offset value and temperature value of the conveyor belt at each time point in each conveying period constitute the conveying parameters of the conveyor belt at each time point in each conveying period.

[0019] Preferably, the operation analysis module is used to analyze and process the conveying parameters of each time point in each conveying period of the conveyor belt, and obtain the conveying signal of the conveyor belt at each time point in each conveying period. The specific analysis method is as follows:

[0020] Obtain the offset value of the conveyor belt at each time point in each conveying period and extract its value, denoted as PY i , where i represents the number of each conveying period, i = 1, 2,..., n, n represents the total number of each conveying period. At the same time, obtain the offset threshold of the conveyor belt in each conveying period from the data storage module, denoted as PYmax;

[0021] According to the formula PL = [(PYmax - PY i ) * a1] / ΔPY, calculate the offset evaluation index PL of the conveyor belt at each time point in each conveying period, where a1 is a set weight factor and ΔPY is a set allowable offset;

[0022] By comparing the offset evaluation index of the conveyor belt at each time point in each conveying period with the set offset evaluation index threshold of the conveyor belt at each time point in each conveying period, if the offset evaluation index of the conveyor belt at each time point in each conveying period is less than the set offset evaluation index threshold, it means that the offset value of the conveyor belt is too large, and an abnormal offset signal is generated and sent to the warning execution module. Otherwise, it means that the offset value of the conveyor belt is small, and a normal offset signal is generated and sent to the warning execution module;

[0023] Obtain the temperature values of the conveyor belt at each time point in each conveying period and extract their numerical values, denoted as WD i At the same time, obtain the reference maximum temperature and reference minimum temperature of the conveyor belt in each conveying period from the data storage module, denoted as WDmax and WDmin respectively;

[0024] According to the formula SW = (WDmax - WD i ) * a2 / (WD i - WDmin) * a3, calculate the temperature evaluation index SW of the conveyor belt at each time point in each conveying period, where a2 and a3 are respectively set weight factors;

[0025] By comparing the temperature evaluation index of the conveyor belt at each time point in each conveying period with the set temperature evaluation index threshold of the conveyor belt at each time point in each conveying period, the specific comparison method is as follows:

[0026] If SW ≥ T1, it means that the temperature value of the conveyor belt at each time point in each conveying period is too low, generate a low-temperature conveying signal and send it to the warning execution module;

[0027] If T1 > SW > T2, it means that the temperature value of the conveyor belt at each time point in each conveying period is normal, generate a normal conveying temperature signal and send it to the warning execution module;

[0028] If SW ≤ T2, it means that the temperature value of the conveyor belt at each time point in each conveying period is too high, generate a high-temperature conveying signal and send it to the warning execution module;

[0029] Among them, both T1 and T2 represent the set temperature evaluation index threshold of the conveyor belt at each time point in each conveying period, and T1 > T2.

[0030] Preferably, the warning execution module is used to perform corresponding warning execution operations on the conveying signals of the conveyor belt at each time point in each conveying period, and its specific warning execution operations are as follows:

[0031] When the warning execution module receives an abnormal offset signal, immediately emit an alarm sound and stop the operation of the drive motor, and arrange maintenance personnel to repair the offset state of the conveyor belt;

[0032] When the warning execution module receives a low-temperature conveying signal, control the warning light to emit a blue warning signal, send high-temperature heat exchange oil into the inside of the support roller through the oil inlet pipe, and use the high-temperature heat exchange oil to circulate inside the support roller, and use the support roller to raise the conveying temperature of the conveyor belt;

[0033] When the warning execution module receives the signal of conveying high temperature, it controls the warning light to emit a red warning signal, sends low-temperature heat exchange oil into the inside of the support roller through the oil inlet pipe, uses the low-temperature heat exchange oil to circulate inside the support roller, and uses the support roller to cool the conveying temperature of the conveyor belt.

[0034] Preferably, the data storage module is used to store the offset threshold, reference maximum temperature, and reference minimum temperature corresponding to each conveying period of the conveyor belt.

[0035] Compared with the prior art, the following beneficial effects are achieved:

[0036] 1. In the present invention, when automatically conveying the steel structure processing raw materials through the conveyor belt, the driving end of the servo cylinder II inside the two opposite connecting frames drives the correction plate to contact both sides of the steel structure processing raw materials, and the positions of the steel structure processing raw materials are corrected by the two correction plates. The steel structure processing raw materials are sent to the conveyor belt through the feeding roller. When automatically conveying the steel structure processing raw materials on the conveyor belt, the two correction plates are used to keep the steel structure processing raw materials in the middle position of the conveyor belt for conveying, thereby effectively preventing the movement trajectory of the conveyor belt from deviating from the original direction and ensuring the stability of the automatic conveying of the steel structure processing raw materials.

[0037] 2. In the present invention, the rotation between the conveyor belt and the transmission frame is synchronously controlled by a single-motor driving method, and then the correction plate on one side of the transmission frame moves synchronously with the automatic conveying of the steel structure processing raw materials on the conveyor belt, ensuring the stable conveying position of the steel structure processing raw materials during the automatic conveying on the conveyor belt, and preventing the problem that the placement distribution position of the steel structure processing raw materials on the conveyor belt is biased to one side, resulting in the movement trajectory of the conveyor frame deviating from the original direction and generating offset or vibration.

[0038] 3. In the present invention, a controller is also provided inside the conveyor frame. By monitoring and analyzing the conveying parameters at each time point in each conveying period of the conveyor belt, the offset evaluation index and temperature evaluation index at each time point in each conveying period of the conveyor belt are obtained. By comparing the offset evaluation index with the set offset evaluation index threshold, an abnormal offset signal is generated. After receiving the abnormal offset signal, the driving motor is immediately controlled to stop running, avoiding the failure of the conveying device caused by the conveyor belt continuing to work in the offset state and improving the operation safety of the conveying device. At the same time, by comparing the temperature evaluation index with the set temperature evaluation index threshold, a conveying low-temperature signal and a conveying high-temperature signal are generated, and heat exchange oil with different temperatures is introduced into the inside of the oil inlet pipe according to different signals, thereby ensuring that the conveyor belt maintains a normal operating temperature during the conveying process and significantly improving the operation safety of the conveyor belt.

[0054] Furthermore, when the steel structure processing raw materials are transported by the automatic conveying device, the steel structure processing raw materials are driven to the conveyor belt 5 through the feeding roller 6, and in order to avoid the placement and distribution position of the steel structure processing raw materials on the conveyor belt 5 being biased to one side, causing the movement trajectory of the conveyor frame 1 to deviate from the original direction, a correction component is provided on the opposite side of the two fixed frames 2, and the correction component includes a transmission frame 11, and the transmission frame 11 is rotatably provided on the opposite side of the two fixed frames 2, and a plurality of driving gears 12 are rotatably provided on the opposite side of the two fixed frames 2, and the surfaces of the plurality of driving gears 12 are meshed with the inner wall of the transmission frame 11 for transmission, and a plurality of connecting frames 13 are fixedly provided on one side of the transmission frame 11, and a servo electric cylinder 2 14 is fixedly provided inside the plurality of connecting frames 13, and a correction plate 15 is fixedly provided at the driving end of the servo electric cylinder 2 14.

[0055] It should be noted that in the present invention, when the steel structure processing raw materials are automatically conveyed through the conveyor belt 5, the driving ends of the servo electric cylinders 14 inside the two opposite connecting frames 13 drive the connecting frames 15 to contact the two sides of the steel structure processing raw materials, and the positions of the steel structure processing raw materials are corrected by using two correction plates 15.

When the steel structure processing raw materials are automatically conveyed on the conveyor belt 5, the two correction plates 15 are used to keep the steel structure processing raw materials in the middle position of the conveyor belt 5 for conveyance, thereby effectively preventing the movement trajectory of the conveyor belt 5 from deviating from the original direction, and ensuring the stability of the automatic conveyance of the steel structure processing raw materials.

[0056] Furthermore, when conveying steel structure processing raw materials, the conveyor belt 5 and the correction component are controlled synchronously by the driving structure arranged inside the conveyor frame 1, and the conveyor frame 1 is provided with a driving component, and the driving component includes a driving motor 16, and the driving motor 16 is fixedly provided inside the conveyor frame 1, and a rotating shaft 17 is fixedly provided at one end of the output shaft of the driving motor 16 through a coupling, wherein the driving motor 16 adopts the cooperation of a servo motor and a reducer; a mounting frame 18 is fixedly provided on the front of the conveyor frame 1, one end of the rotating shaft 17 passes through the conveyor frame 1 and extends to the inside of the mounting frame 18, the front ends of the two driving rollers 4 pass through the conveyor frame 1 and extend to the inside of the mounting frame 18, and sprockets 19 are fixedly provided on one end of the rotating shaft 17 and the two driving rollers 4, and the surfaces of the three sprockets 19 are connected by chains 20 for transmission.

[0062] By real-time monitoring the operating temperature of the conveyor belt 5, heat exchange oil liquid is fed into the interiors of a number of support rollers 7 through the oil inlet pipe 31 and the oil outlet pipe 32. The heat exchange oil liquid flows inside the number of support rollers 7, and the number of support rollers 7 is used to heat or cool the surface of the conveyor belt 5, thereby avoiding the problem that the conveyor belt is prone to failures due to overheating or overcooling during the transportation of steel structure processing raw materials.

[0063] Embodiment 3:

[0064] Please refer to Figure 9 As shown, specifically, a controller is further arranged inside the conveying frame 1, and an operation monitoring module, an operation analysis module, an early warning execution module, and a data storage module are arranged inside the controller. The operation monitoring module is respectively connected to the operation analysis module and the data storage module, and the operation analysis module is connected to the early warning execution module.

[0065] The operation monitoring module is used to monitor and process the conveying parameters of the conveyor belt at each time point in each conveying period. The specific monitoring method is as follows:

[0066] The offset distance of the conveyor belt at each time point in each conveying period is obtained through a displacement sensor, and the offset value of the conveyor belt at each time point in each conveying period is obtained.

[0067] The conveying temperature of the conveyor belt at each time point in each conveying period is obtained through a temperature sensor, and the temperature value of the conveyor belt at each time point in each conveying period is obtained.

[0068] The conveying parameters of the conveyor belt at each time point in each conveying period are composed of the offset value and the temperature value of the conveyor belt at each time point in each conveying period.

[0069] The operation analysis module is used to analyze and process the conveying parameters of the conveyor belt at each time point in each conveying period to obtain the conveying signal of the conveyor belt at each time point in each conveying period. The specific analysis method is as follows:

[0070] Obtain the offset value of the conveyor belt at each time point in each conveying period and extract its numerical value, denoted as PY i, where \(i\) represents the number of each conveying period, \(i = 1, 2,\cdots, n\), and \(n\) represents the total number of all conveying periods. Meanwhile, obtain the offset threshold corresponding to each conveying period of the conveyor belt from the data storage module, denoted as \(PY_{max}\).

[0071] According to the formula \(PL=[(PY_{max}-PY i )*a_1] / \Delta PY\), calculate the offset evaluation index \(PL\) of each time point corresponding to each conveying period of the conveyor belt, where \(a_1\) is a set weight factor and \(\Delta PY\) is a set allowable offset.

[0072] By comparing the offset evaluation index of each time point corresponding to each conveying period of the conveyor belt with the set offset evaluation index threshold of each time point corresponding to each conveying period of the conveyor belt, if the offset evaluation index of each time point corresponding to each conveying period of the conveyor belt is less than the set offset evaluation index threshold, it indicates that the offset value of the conveyor belt is too large, generate an abnormal offset signal and send it to the warning execution module; otherwise, it indicates that the offset value of the conveyor belt is small, generate a normal offset signal and send it to the warning execution module.

[0073] Obtain the temperature value of each time point corresponding to each conveying period of the conveyor belt and extract its value, denoted as \(WD\) i , and at the same time obtain the reference maximum temperature and reference minimum temperature corresponding to each conveying period of the conveyor belt from the data storage module, denoted as \(WD_{max}\) and \(WD_{min}\) respectively.

[0074] According to the formula \(SW=(WD_{max}-WD i )*a_2 / (WD i -WD_{min})*a_3\), calculate the temperature evaluation index \(SW\) of each time point corresponding to each conveying period of the conveyor belt, where \(a_2\) and \(a_3\) are set weight factors respectively; specifically, \(WD_{max}\) takes the value of \(260^{\circ}C\), \(WD_{min}\) takes the value of \(5^{\circ}C\), and the value of \(WD i is determined according to the values collected at each time point corresponding to each conveying period of the conveyor belt. In addition, the weight factor \(a_2 = 1.25\), \(a_3 = 2.35\), and thus calculate the temperature evaluation index \(SW\) of each time point corresponding to each conveying period of the conveyor belt.

[0075] By comparing the temperature evaluation index of each time point corresponding to each conveying period of the conveyor belt with the set temperature evaluation index threshold of each time point corresponding to each conveying period of the conveyor belt, the specific comparison method is as follows:

[0076] If \(SW\geq T_1\), it indicates that the temperature value of each time point corresponding to each conveying period of the conveyor belt is too low, generate a conveying low-temperature signal and send it to the warning execution module;

[0077] If T1 > SW > T2, it indicates that the temperature values of the conveyor belt at each time point in each conveying period are normal. A normal conveying temperature signal is generated and sent to the warning execution module;

[0078] If SW ≤ T2, it indicates that the temperature values of the conveyor belt at each time point in each conveying period are too high. A high-temperature conveying signal is generated and sent to the warning execution module;

[0079] Among them, both T1 and T2 represent the threshold values of the temperature evaluation index for the conveyor belt at each time point in each conveying period, and T1 > T2. The values of T1 and T2 are respectively related to the lowest working temperature and the highest working temperature of the conveyor belt. The value of T1 is slightly less than the highest working temperature of the conveyor belt, and the value of T2 is slightly greater than the lowest working temperature of the conveyor belt; specifically, it is manifested as:

[0080] Through the set threshold values of the temperature evaluation index for the conveyor belt at each time point in each conveying period, where the range of the temperature evaluation index threshold is 2.38 - 27.51, and the values of T1 and T2 are 18.98 and 6.51 respectively;

[0081] When the temperature evaluation index SW of the conveyor belt at each time point in each conveying period ≥ 18.98, it is determined that the temperature values of the conveyor belt at each time point in each conveying period are too low. A low-temperature conveying signal is generated and sent to the warning execution module;

[0082] When the temperature evaluation index 6.51 < SW < 18.98 of the conveyor belt at each time point in each conveying period, it is determined that the temperature values of the conveyor belt at each time point in each conveying period are normal. A normal conveying temperature signal is generated and sent to the warning execution module;

[0083] When the temperature evaluation index SW of the conveyor belt at each time point in each conveying period ≤ 6.51, it is determined that the temperature values of the conveyor belt at each time point in each conveying period are too high.
