Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of modeling optimization, more particularly, the present application relates to a Bentley-based intelligent optimization modeling method and system for a belt conveyor. BACKGROUND

[0002] As an important continuous material conveying device, the belt conveyor is widely used in various industrial scenes and plays an important role in improving material transportation efficiency and reducing work intensity. With the intelligent development of industrial systems, the design of existing conveying equipment has generally introduced three-dimensional modeling and simulation verification tools, such as modeling through the Bentley software platform. However, the existing modeling technology still has many problems, which limits the rapid adaptation and efficient response of the engineering modeling system in diversified conveying scenes.

[0003] The existing three-dimensional modeling technology often aims at the global optimization of the overall model when modeling and optimizing the belt conveyor, but the transmission path in the belt conveyor is obviously the core structure for realizing the main function of the device, and the existing modeling technology often does not perform targeted optimization for the path modeling of this core structure, resulting in the existence of layout errors or low precision even after global optimization modeling. In terms of path modeling, the existing three-dimensional modeling technology is relatively rigid in the layout logic of the carrier roller, and fixed spacing is often used for layout, which cannot be adapted to specific working conditions. For example, the conveying belt may have significant bending or angle changes in different sections of the path, and the existing three-dimensional modeling technology does not actively identify the path sections, resulting in fixed layout ideas for carrier rollers, affecting the stability of the conveyor. In addition, the existing path modeling has weak response capability for the material falling area of the actual working condition, often does not actively detect the range of the material falling area, and still uses fixed spacing to lay ordinary carrier rollers, which can easily lead to insufficient support in the material falling area, reducing the transmission efficiency and the service life of the conveying belt. Moreover, the length of the conveying belt after the carrier roller layout in the actual working condition is often not an integer multiple of the standard layout spacing, which leads to the existence of a part of the area without carrier roller layout, and the existing three-dimensional modeling technology easily ignores this situation, resulting in the existence of areas without carrier roller layout in the constructed path modeling, which conflicts with the actual situation and is difficult to be directly applied to the industrial field.

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

Merge the optimal three-dimensional transmission path with the remaining component models to obtain optimized belt conveyor modeling; send the optimized belt conveyor modeling to a preset industrial data platform for storage.

[0019] In this embodiment, the structural parameter input data of the belt conveyor includes, for example, belt width parameters such as length and width, conveying speed, inclination angle, material density, component size parameters, and motor power, etc. The data cleaning is achieved by missing value filling and outlier processing on the structural parameter input data to obtain higher quality accurate equipment structure data. Based on the structure parameters and position parameters related to the conveyor belt in the structural parameter input data, three-dimensional modeling is performed using a modeling engine to obtain a three-dimensional transmission path.

[0020] The path section recognition method includes: The total length of the three-dimensional transmission path is calculated, and the path nodes in the three-dimensional transmission path are recognized. The total length is divided based on the path nodes to obtain path sub-sections. The path nodes are spatial sampling points when modeling the path. The total length refers to the overall length of the three-dimensional coordinate curve of the three-dimensional transmission path. Any two consecutive path nodes are taken as a path sub-section to obtain several path sub-sections.

[0021] The drum position coordinates of the belt conveyor are acquired, and if the spatial distance between the tail path node of any one path subsegment and the drum position coordinates is equal to a preset first threshold value, the path subsegment and all previous path subsegments are set as a starting segment in the set path direction, wherein the drum position coordinates are coordinates of a position of a drum modeling center point set by the modeling engine based on known accurate equipment structure data; any one path subsegment is selected, and the three-dimensional distance between the last path node in the path subsegment and the drum position coordinates is calculated, and if the distance is equal to a preset first threshold value, it is indicated that the segment formed by the field and all previous fields is close to the driving structure region of the conveying belt, and is therefore marked as a starting segment; wherein the preset first threshold value refers to a standard distance set based on industrial knowledge and experience in the relevant field.

[0022] The tangential change rate of any adjacent path node after the starting segment is calculated, and the continuous path subsegments with an absolute value of the tangential change rate greater than a preset second threshold value are set as transition segments, wherein the tangential change rate refers to the change amplitude of the angle of the direction vector of the adjacent path nodes in the tangent direction; since the angle change direction can be positive or negative, the change amplitude is determined by calculating the absolute value of the tangential change rate, and the second threshold value is set based on historical implementation experience, and when the tangential change rate is greater than the second threshold value, it is indicated that path fluctuations occur multiple times in the continuous multiple adjacent subsegments, and therefore the segment formed by these continuous path subsegments is set as a transition segment.

[0023] The spatial projection point of the center line of the material drop port of the belt conveyor is detected, and the range in which the path center position in the set path direction coincides with the spatial projection point is taken as a material drop segment, wherein when the belt conveyor is running, the material will fall onto the conveying belt, and therefore only the spatial projection points when and after the material is dropped need to be compared with the continuous path center positions in the path direction, and if the two kinds of points coincide, it is indicated that the coincident range is the region in which the material falls onto the conveying belt, and therefore the segment covered by the coincident range is set as a material drop segment.

[0024] The path segment spacing adjustment mode includes: The nearest path node in the starting segment with the smallest spatial distance from the drum position coordinates is identified, a node offset function is constructed, an offset value is calculated by using the node offset function, the position of the nearest path node is offset based on the offset value, and the initial arrangement node coordinates of the roller are output.

[0025] The calculation formula of the node offset function is: ; wherein, The function value of the node offset function is the offset value; represents the known outer diameter of the drum; represents the drum climb-out distance compensation coefficient obtained by querying the industrial parameter database, and is used to compensate the natural inclined distance of the conveying belt after climbing out of the drum surface, and is set as 0.5 in this embodiment. ; represents the maximum roller diameter; represents the roller interference compensation coefficient obtained by querying the industrial parameter database, which is used for dynamic compensation of the structural envelope conflict of the roller, and is set to 0.2 in the embodiment; ; represents the minimum safe installation spacing constant set based on implementation experience, and the value ranges from 0.5 to 1.5; ; It should be noted that the units in the above node offset function are all ; Based on the offset value, the last path node is offset along the set path direction, and the position of the final node is the initial arrangement node coordinate of the roller.

[0026] Starting from the initial arrangement node coordinate of the roller, all path nodes are sequentially traversed in the set path direction to obtain nodes in the transition section and nodes in the material falling section, respectively. By traversing the nodes in the set path direction, the nodes in the transition section and the nodes in the material falling section are labeled respectively.

[0027] The spacing correction parameters of the nodes in the transition section and the nodes in the material falling section in the historical node record are obtained, the product of the spacing correction parameters and the preset standard arrangement spacing is calculated, and the transition section arrangement spacing and the material falling section arrangement spacing are output respectively. Based on the transition section arrangement spacing and the material falling section arrangement spacing, the roller nodes in the transition section and the material falling section are arranged, wherein the spacing correction parameter refers to the parameter set by historical experience and engineering component specification, and there are corresponding spacing correction parameters for different path sections. It is used to dynamically adjust the roller arrangement spacing according to the structural complexity and stress condition of different path sections, so that the arrangement point is more suitable for the working condition; wherein the preset standard arrangement spacing refers to the standard spacing under general working conditions; the transition section arrangement spacing and the material falling section arrangement spacing are used as the basis for roller node arrangement, and the roller nodes in the transition section and the material falling section are arranged.

[0028] The section included angle of the tail path node of the former section and the head path node of the latter section in any two adjacent path sections is measured, and if the section included angle is greater than the preset included angle threshold, a buffer section is inserted and a roller node is arranged in the buffer section. Wherein, the included angle of the direction vector of the tail path node of the former section and the direction vector of the head path node of the latter section in the adjacent path sections is calculated, and the included angle threshold is set based on historical experience. If the included angle is greater than the preset included angle threshold, it means that the path structure has a large turning amplitude. Therefore, a buffer section needs to be added between the two adjacent path sections with large section included angle. The length of the buffer section is set based on historical implementation experience and existing theory, and a plurality of roller nodes are arranged in the buffer section at equal intervals, so that the adjacent path sections are flexibly connected in space. The path sections with arranged roller nodes and the path sections without arranged roller nodes are connected to obtain a section adjusted transmission path.

[0029] The way of supporting the loading structure includes: A path node at the midpoint of the path length in the blanking section is identified as a blanking center node, wherein the blanking center node refers to a path node at one half of the path length of the blanking section, which is a reference datum point for subsequent operations.

[0030] The transmission speed of the belt conveyor is obtained, and the material drop height at the blanking center node is detected, and a first extension distance is obtained by weighted summation of the transmission speed and the material drop height, wherein the transmission speed is a parameter in the known accurate equipment structure data and can be directly extracted; the material drop height is obtained by measuring the Z-axis coordinate difference between the blanking position and the blanking center node; and the weights of the transmission speed and the material drop height are set based on historical implementation experience for calculating the first extension distance.

[0031] A second extension distance is obtained by weighting the known industrial blanking frequency, wherein the known industrial blanking frequency refers to the number of material unloading times per unit time in the industrial specification, and the weight of the work intensity is set based on historical implementation experience for weighting the known industrial blanking frequency to obtain the second extension distance.

[0032] The first extension distance and the second extension distance are respectively extended forward and backward from the blanking center node as the datum, and a front support section and a rear support section are obtained, the first extension distance and the second extension distance are both taken from the blanking center node as the starting point, and the first extension distance is extended upstream and the second extension distance is extended downstream; wherein the first extension distance is used to process the influence of the process of the material starting to fall to the impact on the conveyor belt, and therefore needs to be calculated based on the transmission speed and the material drop height; the front support section is composed of the first extension distance, and this section exists to avoid damage to the conveyor belt caused by high transmission speed and large material drop impact; the second extension distance refers to the extension distance of the structural fatigue influence caused by the repeated falling of the material and propagating backward, representing the areas where the repeated load may cause structural degradation of the subsequent path structure, and these areas need to be supported and reinforced, and therefore need to be calculated based on the known industrial blanking frequency.

[0033] The material height differences corresponding to all path nodes in the front support section are calculated, and the mean square deviation of all material height differences is obtained to obtain a front support height fluctuation value, wherein the mean square deviation of all material height differences is calculated to quantify the undulation degree of the path, that is, the front support height fluctuation value.

[0034] The contact pressure in the front support section at each material blanking is obtained, and the impact pressure of the front support section is calculated based on the contact pressure, wherein the impact pressure of the section is obtained by dividing the contact pressure by the contact area of the front support section.

[0035] The forward support height fluctuation value and the impact pressure are normalized to obtain a forward support arrangement density, wherein the forward support height fluctuation value and the impact pressure are normalized and summed to obtain the forward support arrangement density, which is used to reflect the arrangement density required by the carrier roller.

[0036] The product of the actual material falling frequency and the material falling pressure per unit time is calculated to obtain a pressure limit value, wherein the obtained pressure limit value is used to reflect the upper limit of fatigue bearing of the conveying belt under long-term carrying working conditions.

[0037] If the forward support arrangement density is higher than a preset density threshold, the forward support section is subjected to support enhancement to obtain an enhanced forward support section; if the pressure limit value is higher than a preset allowable limit, the rear support section is subjected to support enhancement to obtain an enhanced rear support section; the enhanced forward support section and the enhanced rear support section are connected with the remaining sections to obtain an enhanced structure transmission path, in the embodiment, the density threshold and the allowable limit are set based on historical implementation experience and industrial specification knowledge, and whether the corresponding section needs to be subjected to support enhancement is judged based on the forward support arrangement density and the pressure limit value; the enhanced section is connected with other sections that are not adjusted to obtain the enhanced structure transmission path.

[0038] The support enhancement mode of the forward support section includes: The normal vector offset of the continuous carrier roller node in the forward support section is detected, and a support response change sequence is constructed based on the normal vector offset, wherein all normal vector offsets are sorted according to the arrangement order of the carrier roller node in the set path direction to obtain the support response change sequence, which is used to reflect the support surface change trend.

[0039] The slope of any node in the support response change sequence is calculated, and if the slope is higher than a preset slope threshold, the corresponding carrier roller node is adjusted to a variable angle carrier roller node, wherein the slope of the support response change sequence represents the support direction change speed, and the greater the value, the greater the change amplitude, in order to prevent the conveying belt from suddenly changing direction to cause floating belt or carrier roller side jump, etc., the carrier roller node with the slope higher than the preset slope threshold is replaced by the variable angle carrier roller node, so that the angle can be dynamically adjusted according to the path shape.

[0040] Meanwhile, buffer roller nodes are added between the two roller nodes closest to the blanking center node in the front support section, wherein the two roller nodes closest to the blanking center node are selected by calculating the Euclidean distance between the roller nodes and the blanking center node in the front support section, and a plurality of buffer roller nodes are added between the two roller nodes, the buffer rollers in this embodiment are rubber-coated rollers or elastic composite rollers, which are used to absorb the impact of the falling material and block the impact wave from being transmitted back to the conveyor belt in the front support section, and the specific number of buffer roller nodes is set based on historical implementation experience; the adjusted front support section is used as the enhanced front support section. The support enhancement of the rear support section includes: The historical load records are collected, and the historical load values of each path node in the rear support section are identified based on the historical load records, wherein the historical load record refers to the support force of the conveyor belt after each material falls in the historical record in each path node in the rear support section, and the average value of the support force of each path node in the selected statistical period is calculated as the historical load value of the path node.

[0041] A sub-section formed by any three consecutive path nodes in the rear support section is extracted, and if the historical load values of the three consecutive path nodes are all higher than the preset bearing threshold, the roller nodes corresponding to the sub-section are replaced with heavy-load roller nodes, wherein the sub-section formed by three consecutive path nodes is the smallest unit for judging overload in this embodiment, and if the historical load values of all path nodes in the smallest unit are higher than the bearing threshold set based on historical implementation experience, it indicates that the conveyor belt may be overloaded in this sub-section, which can easily cause fatigue or damage to the local area of the conveyor belt. Therefore, the roller nodes installed in the above-mentioned sub-section are replaced with heavy-load roller nodes; in this embodiment, the heavy-load roller adopts a high-strength alloy steel shaft to improve the fatigue life of the conveyor belt; and the adjusted rear support section is used as the enhanced rear support section.

[0042] The position clipping includes: The distance from the tail path node of the blanking section of the enhanced structure transmission path to the path termination node is calculated, which is set as the end residual length, and the corresponding section is set as the tail section, wherein the end residual length refers to the distance from the last path node of the blanking section of the enhanced structure transmission path to the last path node of the entire enhanced structure transmission path; it should be noted that in this embodiment, the entire enhanced structure transmission path does not end at the blanking section, but there is a section for ending, so the section corresponding to the above-mentioned end residual length is set as the tail section, and the tail section in the original state is not arranged with roller nodes.

[0043] The tail section is equally divided, and a roller node is arranged at the midpoint of each equally divided sub-section, wherein the tail section is divided into several sub-sections according to a set distance, and a roller node is arranged at the midpoint of each equally divided sub-section, so as to ensure that the tail section roller node arrangement is continuous and uniform.

[0044] If the residual length of the tail section at the end is greater than or equal to a preset end allowable distance threshold, the tail section is determined as an unclosed section, wherein the preset end allowable distance threshold is a distance threshold set based on historical implementation experience, and if the residual length at the end is greater than or equal to the preset end allowable distance threshold, it means that there is still a lot of residual space in the tail section, so it is determined as an unclosed section.

[0045] The number of additional nodes is calculated based on the distance between the last roller node in the tail section and the path termination node, wherein the calculation formula of the number of additional nodes is: ; wherein represents the number of additional nodes; represents the distance between each roller node in the tail section before the additional nodes are added; represents the distance from the last roller node to the path termination node; represents the floor symbol; it should be noted that The value of .

[0046] The distances between all roller nodes in the tail section are compressed, and additional nodes are added, so that the last roller node is inscribed in the path termination node, wherein the additional node refers to the roller node that needs to be added in the tail section. By compressing the distances between all roller nodes in the tail section, the additional node can be placed, and it is also necessary to ensure that the distances between all roller nodes after adding the additional node are still equal and that the last roller node is inscribed in the path termination node. The stability and load balance of the tail section of the belt conveyor are ensured.

[0047] If the residual length of the tail section at the end is less than the preset end allowable distance threshold, the last roller node is shifted forward by a preset minimum distance as a termination roller node, and a sub-path after the termination roller node is deleted, wherein if the residual length of the tail section at the end is less than the preset end allowable distance threshold, it means that the residual space of the tail section is too short. In this embodiment, the last roller node is shifted forward by a distance, which is a preset minimum distance set based on historical implementation experience, and the roller node is used as a termination roller node. A section of path after the termination roller node is deleted to ensure that the termination roller node is inscribed in the path termination node. It should be noted that after the last roller node is shifted forward, the distances between all roller nodes need to be adjusted to ensure that all distances are equal. The adjusted enhanced structure transmission path is set as a closed structure transmission path.

[0048] The manner of judging the space conflict includes: Extracting the roller position coordinates in the closed structure transmission path, setting the roller center axis based on the set path direction, and generating a rectangular roller layout area along the direction orthogonal to the roller center axis, wherein generating a rectangular roller layout area along the direction orthogonal to the roller center axis refers to extending to both sides based on the roller center axis as a reference line, and synchronously setting the height and width to generate a rectangular three-dimensional area, that is, the rectangular roller layout area, wherein the set height and width are both set based on historical implementation experience.

[0049] Obtaining motor model parameters, and generating a motor component layout area on an arbitrary side of the roller center axis of the rectangular roller layout area based on the motor model parameters, wherein the motor model parameters refer to the size parameter data of the motor model, and the motor component layout area is generated on the arbitrary side of the roller center axis based on the size parameter data of the motor model.

[0050] Judging whether the rectangular roller layout area and the motor component layout area exist in space overlap, measuring the space intersection volume between the two areas, and in this embodiment, using three-dimensional Boolean operation to analyze the real intersection part between the rectangular roller layout area and the motor component layout area, and outputting the space intersection volume.

[0051] If the space intersection volume is greater than a preset conflict tolerance threshold, it is determined that there is a space conflict, wherein the space intersection volume is compared with the preset conflict tolerance threshold set based on historical implementation experience, and if the space intersection volume is higher than the preset conflict tolerance threshold, it means that the overlapping part volume is too large, which is easy to cause assembly space conflict; for example, when the belt conveyor is laid out, the bearing seat of the roller is arranged symmetrically left and right, and at this time, if a motor needs to be installed, a conflict is easy to occur.

[0052] Identifying the bearing seat arrangement node of the rectangular roller layout area, and judging the occupation of the bearing seat arrangement node, wherein the position of the bearing seat arrangement node in the rectangular roller layout area is identified based on historical implementation experience, and whether the position of the bearing seat arrangement node is occupied is judged.

[0053] If there is no occupation, the component model of the rectangular roller layout area related to the space conflict is moved to the side of the non-motor component layout area, and the bearing seat arrangement node on the side of the space conflict is moved outward along the roller center axis by a permitted offset distance, wherein the component model of the rectangular roller layout area related to the space conflict refers to the component model related to the roller in the area where the rectangular roller layout area and the motor component layout area exist in overlap; moving the bearing seat arrangement node on the side of the space conflict outward along the roller center axis by a permitted offset distance refers to translating the bearing seat arrangement node on the side of the space conflict along the vertical direction of the roller center axis by a permitted offset distance set based on historical implementation experience, so that the motor no longer overlaps with the bearing seat arrangement node position.

[0054] If the occupation or the allowed offset distance is higher than the preset maximum allowed distance, the bearing seat arrangement nodes on both sides of the drum central axis are moved outwardly and obliquely by an oblique offset distance, wherein if the positions of the bearing seat arrangement nodes on both sides are occupied by the motor or other components, or the allowed offset distance is higher than the preset maximum allowed distance based on historical implementation experience, the bearing seat arrangement nodes on both sides are offset in a specific angular direction along the drum central axis by a specific angle, and by an oblique offset distance based on historical implementation experience, to achieve obstacle avoidance assembly between model components; the adjusted bearing seat arrangement nodes are added to the closed structure transmission path to obtain a risk avoidance transmission path.

[0055] The way of evaluating the component combination effect includes: Extract the path parameters of the current risk avoidance transmission path, match the path parameters with the preset component model library, and output a preliminary feasible component combination scheme, wherein the path parameters include, for example, the total path length, the curvature change, the spatial angle, the roller layout density, and the size parameters of the connected components such as motors or drums; match the path parameters with the preset component model library, and screen the preliminary feasible component combination scheme from the geometric characteristics of various component models.

[0056] Three-dimensional simulation is performed on any preliminary feasible component combination scheme to detect whether there is a mismatch between the component combination layout size and the path parameters, and the preliminary feasible component combination scheme that does not match is deleted, wherein by performing three-dimensional simulation in the corresponding unified space coordinate system, it is judged whether there is an abnormal situation such as insufficient layout length, vertical error exceeding the limit, corner angle not meeting the requirements, or component layout overlapping, and the size-related parameters of each component cannot match the path parameters, and these preliminary feasible component combination schemes that do not match are deleted.

[0057] The path length proportion of the remaining preliminary feasible component combination schemes in the risk avoidance transmission path is calculated, and the preliminary feasible component combination scheme with the largest path length proportion is extracted as the candidate preferred scheme, wherein the path length proportion is calculated to obtain the effective proportion of the path directly covered after the layout is completed, and if the largest path length proportion path after the layout is completed is considered as the most suitable component combination scheme, it is the candidate preferred scheme.

[0058] If there are candidate preferred solutions with the same path length proportion, the solution with the least number of component layouts is selected as the optimal combination solution. The optimal combination solution is connected with the risk-averse transmission path to obtain an optimal three-dimensional transmission path. If there are candidate preferred solutions with the same path length proportion, the solution with the least number of component layouts is selected as the optimal combination solution to make the complete model more accurate. If there is no solution with the same path length proportion, the candidate preferred solution is determined as the optimal combination solution.

[0059] The modeling and merging manner with the remaining component models includes: The remaining components and the related components in the optimal three-dimensional transmission path are geometrically connected in the known equipment order to obtain a structure framework model of the belt conveyor. The geometric docking nodes of each component in the structure framework model are identified, and the space jump value between each pair of geometric docking nodes is measured. If the space jump value is higher than the preset assembly error threshold, spatial correction is performed. In this embodiment, the geometric docking node refers to the node of the connection area of two components, such as the support component connection point and the model boundary connection point. The space jump value refers to the offset of the spatial distance of two geometric docking nodes compared with the spatial distance of the theoretical model component connection.

[0060] If the space jump value is higher than the preset assembly error threshold based on the model standard specification, it indicates that the error between the two components is large. Based on historical implementation experience, the layout posture of the model components corresponding to the pair of geometric docking nodes is adjusted to make the transition of each part smooth without geometric disconnection, and spatial correction is realized.

[0061] The adjusted structure framework model is subjected to spatial layout alignment to obtain an optimized belt conveyor modeling. Through spatial layout alignment, the spatial positions of all components in the model are logically unified in a unified spatial coordinate system, and the optimized belt conveyor modeling is obtained.

[0062] The embodiment starts from the aspect of path optimization, obtains an optimized path through distance adjustment, position cutting and risk avoidance on path modeling in sequence, evaluates the component combination effect of the optimized path, finally splices the path modeling with other component modeling to form a complete belt conveyor model, and realizes targeted optimization of the model; compared with existing experience, the problems of belt wear and roller damage caused by material falling impact are effectively relieved by identifying path sections and adjusting the layout distance of roller nodes in the sections, and the support of the path after laying rollers is enhanced, the applicability of path modeling in actual scenes is improved; the accurate closing of the tail section of the path is realized by combining position cutting with path length, and the modeling error is reduced; in terms of spatial conflict, the position offset of the bearing seat node is adjusted by detecting the spatial overlap relationship between components, and the structural conflict is reduced; finally, the optimal combination scheme is selected by matching the component combination scheme, and a complete modeling is constructed, the accuracy and design efficiency of the modeling process are improved, the belt conveyor model is more fine and reasonable in assembly, and can be directly used in related engineering fields.
