Description

Technical Field

[0001] The present application generally relates to the field of industrial material conveying equipment, and more particularly to a gantry-type adjustable TBM continuous belt conveyor slag belt anti-turnover device. Background Art

[0002] In the field of industrial production, especially in the material transportation process of mining, steel, ports, power plants and other industries, the conveyor belt system, as the core equipment, undertakes the task of continuous transportation of large-scale materials. However, due to long-distance transportation or heavy loads, the conveyor belt is easily disturbed by various external factors during operation, such as uneven material distribution, unbalanced belt tension during operation, and uneven force on rollers. These factors can easily cause conveyor belts to deviate, flip, and other faults, thereby affecting production efficiency and equipment stability.

[0003] At present, common protective measures for the problem of conveyor belt flipping include installing fixed physical correction devices on both sides of the belt or using adjustable rollers to slow down the belt deviation. However, these traditional protection methods have defects such as slow response and complex manual adjustment, and often cannot effectively respond to the rapidly changing belt operation status in a timely manner. In addition, uneven distribution of materials on the conveyor belt is also the main cause of belt deviation.

DETAILED DESCRIPTION

[0057] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant content, rather than to limit the present application. It is also necessary to explain that, for ease of description, only the parts related to the present application are shown in the accompanying drawings.

[0058] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0059] In order to make the description of the following embodiments clear and concise, a brief introduction to the related technology is first given:

[0060] The Tunnel Boring Machine (TBM) continuous belt conveyor is a highly efficient mucking and transportation equipment used in tunnel construction. It mainly drives the drum through a motor, and the drum drives the belt to circulate, continuously transporting the slag generated during the TBM excavation process from the tunnel face to the designated slag unloading site outside the tunnel. Compared with traditional mucking and transportation methods (such as rail mining cars, etc.), the TBM continuous belt conveyor has the advantages of efficient and continuous transportation, adaptability to long-distance transportation, and high degree of automation.

[0061] However, during the transportation of slag, if the slag is unevenly distributed on the belt and there is too much slag on one side, the forces on both sides of the belt will be unbalanced, causing the belt to deviate to the side with less slag; or, due to the failure of the tensioning device or the uneven elastic deformation of the belt itself, the tension of different parts of the belt during operation will be different. The side with greater tension will pull the belt to that side, causing the belt to deviate. These problems will affect production efficiency and equipment stability.

[0062] In view of this, the present application designs a communication-connected correction mechanism and a monitoring and control mechanism. When the conveyor belt is transporting materials, the rollers of the correction mechanism are allowed to roll at the same time. The monitoring and control mechanism determines whether the conveyor belt currently has an offset or flipping problem based on the roller axis angle data detected in real time by the angle sensor. When the conveyor belt has an offset or flipping problem, the correction roller is controlled to contact the conveyor belt to correct the position of the conveyor belt until the conveyor belt returns to its normal track and runs stably, and the correction operation is stopped to avoid equipment failure and production interruption due to offset or flipping of the conveyor belt.

[0063] In order to make the gantry-type adjustable TBM continuous belt conveyor slag belt anti-turnover device provided in the embodiment of the present application clearer and easier to understand, the method is introduced below with reference to the accompanying drawings. Figure 1 As shown, this figure is a three-dimensional diagram of a gantry-type adjustable TBM continuous belt conveyor slag belt anti-turnover device provided in an embodiment of the present application, and the device includes:

[0064] A base 1 is provided with a conveyor belt 2 for transporting materials; a gantry 3 is also provided on the base 1, and the gantry 3 is straddled above the conveyor belt 2; wherein the gantry 3 serves as the basic bearing component of the device and is used for installing a structure that realizes an anti-deviation or belt-turning function.

[0065] The deflection correction mechanism is arranged on the door frame 3; the deflection correction mechanism comprises a roller in rolling contact with the conveyor belt 2 and a correction roller 12 for contacting the conveyor belt 2; an angle sensor 18 is arranged at the axis of the roller, and the angle sensor 18 is used to detect the angle data of the axis of the roller in real time;

[0066] The monitoring and control mechanism is communicatively connected with the deviation correction mechanism, and is used for judging whether the conveyor belt 2 has deviation or flipping problems according to the roller axis angle data detected by the angle sensor 18, and when the conveyor belt 2 has deviation or flipping problems, controlling the correction roller 12 to contact with the conveyor belt 2 to correct the position of the conveyor belt 2.

[0067] The monitoring and control mechanism can control the rolling contact between the roller of the correction mechanism and the surface of the conveyor belt 2. When the conveyor belt 2 is transporting materials, the rollers rotate at the same time, and the angle sensor 18 monitors the roller axis angle data in real time. The monitoring and control mechanism obtains the angle data and determines whether the conveyor belt 2 has an offset or flipping problem based on the angle data. When the angle data exceeds the preset threshold, it is determined that the conveyor belt 2 has an offset or flipping problem. At this time, the monitoring and control mechanism controls the correction roller 12 to contact the conveyor belt 2 to correct the position of the conveyor belt 2, so that the conveyor belt 2 can quickly resume normal operation and avoid equipment failure and production interruption due to offset or flipping of the conveyor belt 2.

[0068] The definition of the roller axis angle data is as follows: when the roller just contacts the conveyor belt 2 and the conveyor belt 2 is in a stationary state, the angle corresponding to the axis position of the roller is defined as 0°. For example, if the clockwise direction is defined as the positive direction, then when the roller rotates clockwise, the angle value measured by the angle sensor 18 will gradually increase from the beginning; conversely, when the roller rotates counterclockwise, the angle value will decrease. In this way, the angle of the roller axis is the angle formed by rotating in the specified direction relative to this zero point position.

[0069] If the angle data does not exceed the preset threshold, it indicates that the current conveyor belt 2 is in normal operation, and the central axis of the offset wheel set 17 is relatively perpendicular to the transmission direction of the conveyor belt 2. When the conveyor belt is offset, the lateral force it generates will cause the axis of the roller to tilt to a certain extent, and the angle data will change significantly at this time. Here, the preset threshold can be set according to actual needs. In addition, when the conveyor belt 2 is in normal operation, a small angle change will occur between the roller and the conveyor belt, and the range of change is much smaller than the preset threshold and can be ignored.

[0070] Furthermore, if Figure 2 As shown, the correction mechanism includes:

[0071] Two electric push rods 5 are arranged in the groove of the door frame 3 and are located at both ends of the groove; the driving end of the electric push rod 5 is provided with a connecting block 6 which is slidably connected with the groove;

[0072] The mounting plate 7 has one end connected to the connecting block 6, and the extending direction of the mounting plate 7 is perpendicular to the transmission direction of the conveyor belt 2; the mounting plate 7 is connected to the correction roller 12 through an angle adjustment component, and the angle adjustment component is used to adjust the inclination angle between the correction roller 12 and the conveyor belt 2, and the openings of the two inclination angles are arranged opposite to each other.

[0073] It should be noted that the driving ends of the two electric push rods 5 are arranged relative to each other. When the two are in working state at the same time, they can simultaneously drive the two connecting blocks 6 to move closer to or farther from each other. Two slide grooves 4 are also provided in the groove. The two slide grooves 4 are arranged in a one-to-one correspondence with the two connecting blocks 6 and are slidably connected, so that the connecting blocks 6 can slide stably. The cross-section of the mounting plate 7 is L-shaped. For example, the mounting plate 7 has a first sub-mounting plate and a second sub-mounting plate arranged perpendicular to each other. The first sub-mounting plate is connected to the corresponding connecting block 6. An angle adjustment component is arranged between the second sub-mounting plate and the first sub-mounting plate, and the angle adjustment component is connected to the correction roller 12 for adjusting the inclination angle between the correction roller 12 and the conveyor belt 2.

[0074] When the conveyor belt 2 is deflected or flipped, the monitoring and control mechanism controls the two electric push rods 5 and the angle adjustment assembly to be in working state, and the electric push rod 5 drives the correction roller 12 to move in a direction perpendicular to the conveyor belt 2 (i.e. Figure 2 The angle adjustment component moves in the vertical direction in the conveyor belt, and adjusts the inclination angle between the correction roller 12 and the conveyor belt 2, so that the correction roller 12 contacts the surface of the conveyor belt 2 and pushes the conveyor belt 2 to reset, that is, drives the conveyor belt 2 to return to the normal operating position.

[0075] Specifically, Figure 3 As shown, the angle adjustment assembly includes:

[0076] An electric telescopic rod 8, the electric telescopic rod 8 is connected to the mounting plate 7, and a shaft block 11 is provided at the driving end of the electric telescopic rod 8;

[0077] A movable plate 9 is rotatably connected to an end of the mounting plate 7 away from the connecting block 6; a mounting seat 10 movably connected to the shaft block 11 is provided on the movable plate 9, and the mounting seat 10 is arranged close to the mounting plate 7;

[0078] The correction roller 12 is installed at one end of the movable plate 9 away from the mounting plate 7; the movable plate 9 is pushed to rotate relative to the mounting plate 7 by the end of the driving shaft of the electric telescopic rod 8, thereby changing the inclination angle between the correction roller 12 and the conveyor belt 2.

[0079] It should be noted that the electric telescopic rod 8 is installed between the first sub-mounting plate and the second sub-mounting plate of the mounting plate 7, which makes the supporting effect of the electric telescopic rod 8 more stable. The moving direction of the driving end of the electric telescopic rod 8 is perpendicular to the transmission direction of the conveyor belt 2, that is, Figure 2 The rotating connection structure of the movable plate 9 and the end of the mounting plate 7 away from the connecting block 6 is provided with a torsion spring, so that the movable plate 9 has a reset function; in addition, a long strip through slot is provided on the mounting seat 10, which is rotatably connected to the shaft block 11.

[0080] When the conveyor belt 2 has an offset or flipping problem and the inclination angle between the correction roller 12 and the conveyor belt 2 needs to be adjusted, the driving end of the electric telescopic rod 8 moves, driving the shaft block 11 to rotate and move in the long strip groove, thereby pushing the movable plate 9 to rotate, thereby changing the inclination angle between the correction roller 12 and the conveyor belt 2.

[0081] Furthermore, if Figure 2 As shown, the correction mechanism also includes:

[0082] A longitudinal plate 13 is arranged on the top of the door frame 3 and is arranged parallel to the transmission direction of the conveyor belt 2; at least one vertical adjustment component is provided on the longitudinal plate 13, and an offset wheel group 17 is provided at the end of the vertical adjustment component. The offset wheel group 17 includes a plurality of rollers, and the vertical adjustment component is used to adjust the contact position between the roller and the conveyor belt 2.

[0083] It should be noted that there are two longitudinal plates 13, which are respectively arranged on both sides of the door frame 3, and the length extension lines of the two longitudinal plates 13 coincide with each other; Figure 2 As shown, the number of vertical adjustment components is two, and the number of rollers included in each offset wheel set 17 is, for example, two.

[0084] Among them, Figure 2 and Figure 4 As shown, the vertical adjustment assembly includes:

[0085] A hydraulic cylinder 14 is provided on the longitudinal plate 13; a transverse plate 15 is provided at the driving end of the hydraulic cylinder 14, and the hydraulic cylinder 14 is used to drive the transverse plate 15 to move in a direction perpendicular to the transmission direction of the conveyor belt 2; both ends of the transverse plate 15 are rotatably connected to a movable frame 16; one end of the movable frame 16 away from the transverse plate 15 is rotatably connected to an offset wheel set 17;

[0086] The damping shaft 33 has two ends which are rotatably connected to the two movable frames 16 respectively.

[0087] It should be noted that the hydraulic cylinder 14 drives the transverse plate 15 to move in a direction perpendicular to the transmission direction of the conveyor belt 2, that is, Figure 2 in the vertical direction; when the vertical adjustment component is in working state, the hydraulic cylinder 14 drives the cross plate 15 to move in the vertical direction, and the two movable frames 16 approach or move away from each other at the same time, so that the rollers of the offset wheel set 17 are in rolling contact with the conveyor belt 2, and the rollers can rotate in real time following the movement of the conveyor belt 2. At this time, the damping shaft 33 generates a certain deformation force, so that there is an interaction force between the two movable frames 16, so that the rollers can be in stable contact with the conveyor belt 2; when the device stops working, the hydraulic cylinder 14 moves upward in the vertical direction, and the offset wheel sets 17 on the two movable frames 16 are reset under the deformation force of the damping shaft 33.

[0088] Furthermore, if Fig. 9 As shown, the monitoring and control mechanism includes:

[0089] A data acquisition module 34, which is used to collect angle data detected by the angle sensor 18 in real time;

[0090] The data processing and analysis module 35 is used to determine whether the conveyor belt 2 has a deviation or a belt turning problem according to the angle data, and obtain an analysis result; the analysis result is that the conveyor belt 2 has a deviation or a belt turning problem, or the conveyor belt 2 does not have a deviation or a belt turning problem;

[0091] A deviation correction control module 36, which is used to control the deviation correction mechanism to adjust the position of the conveyor belt 2 in real time when the analysis result shows that the conveyor belt 2 has a deviation or a belt flipping problem;

[0092] The output and alarm module 37 is used to issue an alarm and display status information when the analysis result shows that the conveyor belt 2 has a deviation or overturning problem. When the analysis result shows that the conveyor belt 2 does not have a deviation or overturning problem, the normal monitoring state is maintained.

[0093] If during the deviation correction process, the monitoring and control mechanism finds that the conveyor belt 2 cannot return to its original position normally, for example, the angle change has not been restored or the system fails, the output and alarm module 37 will send an alarm signal to prompt the operator to check or take further measures. If the deviation or belt flipping problem is serious and cannot be solved by the deviation correction mechanism, the monitoring and control mechanism can trigger the emergency stop mechanism to avoid damage to the equipment or the conveyor belt 2.

[0094] In addition, if Fig.10 As shown, there are multiple angle sensors 18, and the monitored area of ​​the conveyor belt 2 is relatively wide to cover the entire bandwidth range. In order to ensure the accuracy and stability of the device, the start condition of the alarm and correction program is not based on the abnormality of a single angle sensor, but according to the following logic:

[0095] The above-mentioned preset thresholds include a sub-warning threshold and a sub-flip threshold;

[0096] Rules for triggering the deviation alarm: Each angle sensor 18 collects the roller axis angle data in real time; if the monitoring value of a single angle sensor 18 exceeds the sub-warning threshold (i.e., a slight deviation in a small range), the output and alarm module 37 issues an "deviation warning", which is only used to prompt the operator, but the deviation correction program is not started for the time being, so as to allow continuous monitoring. When multiple angle sensors 18 exceed the sub-warning threshold continuously (for example, two or more adjacent angle sensors 18 exceed the standard at the same time, or the distribution of the angle sensors 18 that exceed the standard affects a certain bandwidth range), the data processing and analysis module 35 determines that the deviation problem may expand and directly triggers the deviation correction program.

[0097] Rules for triggering the belt turning alarm: If the monitoring value of any angle sensor 18 exceeds the sub-belt turning threshold, it indicates that the conveyor belt 2 is currently at a risk of significant tilt or even turning over. The monitoring control mechanism immediately triggers the "belt turning alarm" and starts the forced deviation correction procedure. If the deviation correction fails, the emergency shutdown process is entered.

[0098] The logic of the two branches, "offset warning" and "tape flip alarm", is divided according to the following criteria:

[0099] Determination range of deviation problem: The output value of the angle sensor 18 is lower than the sub-flip threshold, but higher than the sub-warning threshold. The deviation problem is usually mild and controllable, which is manifested in a smaller deviation range in the angle data, for example: Deviation warning threshold range: The angle change is within the range of 3° to 10°;

[0100] The deviation warning is mainly for belt imbalance or deviation tendency caused by slight deviation.

[0101] Scope of determination of belt flipping problem:

[0102] The output value of the angle sensor 18 is higher than the sub-band turning threshold.

[0103] The belt flipping problem indicates that the conveyor belt 2 has a tendency to deviate violently or even flip, and the change of the axis angle detected by the angle sensor 18 is obviously abnormal. For example: the belt flipping alarm threshold range: the angle change exceeds 10°.

[0104] The belt flip alarm is usually accompanied by obvious operating abnormalities, requiring rapid initiation of a deviation correction procedure or even an emergency shutdown.

[0105] The data acquisition module 34 collects the angle data of each angle sensor 18 in real time.

[0106] The data processing and analysis module 35 compares the angle data of each angle sensor 18 with the sub-warning threshold and the sub-flip threshold one by one:

[0107] The angle data of the single angle sensor 18 exceeds the sub-warning threshold but is lower than the sub-flip threshold: it is determined to be a slight deviation and a deviation warning is issued.

[0108] The angle data of multiple angle sensors 18 exceed the sub-warning threshold and are widely distributed: it is determined to be a trend of deviation expansion, and the correction program is triggered.

[0109] The angle data of a single or multiple angle sensors 18 exceeds the sub-tape flipping threshold: it is determined to be a tape flipping problem, a tape flipping alarm is issued and a forced deviation correction or emergency shutdown procedure is initiated.

[0110] Furthermore, the deviation correction control module 36 includes:

[0111] Action instruction generating unit: used to generate action instructions required by the actuator according to the analysis results of the data processing and analysis module 35;

[0112] Actuator control unit: used to drive the deviation correction mechanism to move and adjust the position of the conveyor belt 2 according to the angle data;

[0113] Feedback control unit: It is used to dynamically adjust the data fed back in real time by the angle sensor 18 during the deviation correction operation; according to the feedback data, the force and direction of the deviation correction device are continuously adjusted through the PID control algorithm to ensure that the conveyor belt 2 gradually returns to the normal position;

[0114] The correction position monitoring unit is used to continuously monitor the angle of the roller during the correction operation, and then determine whether the correction operation has achieved the expected effect, that is, whether the conveyor belt 2 has been reset, to prevent over-correction or secondary belt turning.

[0115] When the conveyor belt 2 returns to its normal operating state, indicating that the correction operation has been completed, the correction control module 36 stops the operation of the correction roller 12 and restores the correction mechanism to the standby state. The monitoring control mechanism continues to monitor the operation of the conveyor belt 2 in real time (i.e., the angle sensor 18 detects the roller axis angle data in real time), thereby keeping the conveyor belt 2 in a normal operating state.

[0116] Furthermore, the deviation correction mechanism further includes: a material leveling component, which is arranged relatively close to the feed end of the conveyor belt 2;

[0117] like Figure 5 and Figure 6 As shown, the screed assembly includes:

[0118] The drive structure and the material-scraping structure, the drive structure and the conveyor belt 2 are rotatably connected to a group of roller shaft components close to the feed end thereof; the material-scraping structure and the drive structure are rotatably connected;

[0119] The driving force of the roller assembly shaft component is transmitted to the material leveling structure via the driving structure, thereby driving the material leveling structure to reciprocate along the transmission direction of the conveyor belt 2 so that the material is evenly distributed on the conveyor belt 2.

[0120] It should be noted that the roller shaft assembly is installed along the running path of the conveyor belt 2 and is located at the bottom of the conveyor belt 2, and is used to support the conveyor belt 2 and the weight of the slag thereon. The roller shaft assembly can reduce the sag of the conveyor belt 2, ensure the smooth operation of the conveyor belt 2, and can reduce the friction between the conveyor belt 2 and other components, thereby extending the service life of the conveyor belt 2.

[0121] Under the action of the roller shaft components and the driving structure, the material leveling structure is driven to run along with the conveyor belt 2. This material leveling structure is similar to a rake structure and can perform real-time material leveling on the material on the conveyor belt 2, so that the material can be spread on the conveyor belt 2, reducing the risk of deviation of the conveyor belt 2 due to material accumulation, ensuring the stable operation of the conveyor belt 2, and further extending the service life of the device.

[0122] Here, the conveyor belt 2 is in an arc shape (low in the middle and high on both sides) when running, which is similar to a U-shape. As a result, during transportation, materials are accumulated in the middle area of ​​the U-shape, and the conveyor belt 2 is prone to deviation. At this time, the material leveling component of the present scheme is required to perform a material leveling operation to spread the material in the middle area of ​​the U-shape so that the material is in a relatively even distribution form to ensure the stable operation of the conveyor belt 2.

[0123] Specifically, Figure 6 As shown, the drive structure includes:

[0124] Two eccentric wheels 19 are respectively connected to a group of roller shaft components of the conveyor belt 2 relatively close to its feed end;

[0125] A movable rod 20, one end of which is rotatably connected to the eccentric wheel 19, and the other end of which is rotatably connected to the moving rod 21; a connecting rod 23 is provided on the moving rod 21; the two connecting rods 23 are connected by a crossbeam 24;

[0126] Two limiting frames 22 are arranged on the base 1 and located at both sides of the conveyor belt 2. The moving rods 21 correspond to the limiting frames 22 one by one and are slidably connected.

[0127] It should be noted that when the conveyor belt 2 is running, the roller shaft components rotate synchronously, thereby driving the eccentric wheel 19 to rotate, driving the movable rod 20 to move, thereby driving the movable rod 21 to slide along the groove on the limit frame 22, so that the connecting rod 23 drives the crossbeam 24 to move back and forth.

[0128] In addition, if Figure 7 and Figure 8 As shown, the material refining structure includes:

[0129] A limiting groove 26, which is provided on the lower surface of the cross beam 24;

[0130] A fixing rod 25, the fixing rod 25 is fixedly connected to the cross beam 24;

[0131] A plurality of adjusting rods 30 are provided, the ends of which are rotatably connected to pulleys 29, and the pulleys 29 are slidably connected to the limiting grooves 26; the adjusting rods 30 are located on the same side of the fixed rods 25, and the fixed rods 25 and the adjusting rods 30 as well as adjacent adjusting rods 30 are connected via distance adjustment units.

[0132] Among them, Figure 7 and Figure 8 As shown, the distance adjustment unit includes:

[0133] A plurality of X-shaped frames 28, wherein the X-shaped frames 28 are arranged between the fixed rod 25 and the adjusting rod 30 and between adjacent adjusting rods 30; adjacent X-shaped frames 28 are rotatably connected via a connecting shaft 32;

[0134] A guide groove 31 is provided on the fixing rod 25 and the adjusting rod 30; a connecting shaft 32 is slidably connected to the guide groove 31;

[0135] The electric telescopic rod 27, the body of the electric telescopic rod 27 is rotatably connected to a connecting shaft 32 in the guide groove 31 on the fixed rod 25, and the driving end of the electric telescopic rod 27 is rotatably connected to another connecting shaft 32 in the guide groove 31 on the fixed rod 25.

[0136] It should be noted that, since materials have different specifications, the material leveling structure is designed to be an adjustable structure to improve the efficiency of spreading the materials and enhance the adaptability and transportation efficiency of the conveyor belt 2.

[0137] Specifically, according to the size of the material, the electric telescopic rod 27 is started to adjust the distance between the multiple adjustment rods 30 and the fixed rod 25: the driving force of the electric telescopic rod 27 will drive the X-shaped frame 28 connected to it to cross-move, so that the distance between the adjustment rod 30 closest to the fixed rod 25 is changed and adjusted, and then under the linkage of the multiple X-shaped frames 28, the distance between the multiple adjustment rods 30 is adjusted. As the distance between the multiple adjustment rods 30 changes, the top pulley 29 will synchronously move inside the limit groove 26, so that the connecting shaft 32 between the two X-shaped frames 28 will synchronously slide inside the guide groove 31, thereby efficiently spreading the material and improving the adaptability and transportation efficiency of the conveyor belt 2. Figure 6 It can be seen that the adjustable distance of the distance adjustment unit is hindered by the limiting groove 26 , and the maximum unfolding length of the multiple adjustment rods 30 thereof is the maximum passing width of the bottom of the U-shaped conveyor belt 2 .
