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, three-dimensional modeling and simulation verification tools have been widely introduced in the design of existing conveying equipment, 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 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 to 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.

[0056] The path section recognition manner includes:

[0057] The total length of the three-dimensional transmission path is calculated, and path nodes in the three-dimensional transmission path are recognized, the total length of the path is divided based on the path nodes, to obtain path sub-sections, wherein the path node refers to a spatial sampling point when the path is modeled; the total length of the path refers to the overall length of the three-dimensional coordinate curve of the three-dimensional transmission path; the path sub-sections are obtained by taking the path nodes as segmentation points and taking the path section between any two continuous path nodes as a path sub-section.

[0058] The drum position coordinates of the belt conveyor are obtained, if the spatial distance between the tail path node of any path sub-section and the drum position coordinates is equal to a preset first threshold value, the path sub-section and all previous path sub-sections are set as a starting section in a set path direction, wherein the drum position coordinates are coordinates of a position where a drum modeling center point set by the modeling engine based on known precise equipment structure data is located; any path sub-section is selected, the three-dimensional distance between the last path node in the path sub-section and the drum position coordinates is calculated, if the distance is equal to the preset first threshold value, it is indicated that the section formed by the field and all previous fields is close to a driving structure region of the conveying belt, and thus is marked as a starting section; wherein the preset first threshold value refers to a standard distance set based on industrial knowledge and experience in the related field.

[0059] The tangential change rate of any adjacent path node after the starting section is calculated, and the continuous path sub-sections with an absolute value of the tangential change rate greater than a preset second threshold value are set as transition sections, 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, when the tangential change rate is greater than the second threshold value, it is indicated that path fluctuations occur in multiple adjacent sub-sections, and thus the section formed by the continuous path sub-sections is set as a transition section.

[0060] The space projection point of the center line of the material falling port of the belt conveyor is detected, and a range in which the path center position in the set path direction coincides with the space projection point is taken as a material falling section, wherein when the belt conveyor is running, the material will fall onto the conveying belt, and therefore only the space projection points when and after the material falls are compared with the continuous path center positions in the path direction, and if the two kinds of points coincide, it is indicated that the coinciding range is the area in which the material falls onto the conveying belt, and therefore the section covered by the coinciding range is set as the material falling section.

[0061] The path section distance adjustment manner comprises the following steps:

[0062] The nearest path node in the starting section with the minimum 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.

[0063] The calculation formula of the node offset function is as follows: ; wherein, The function value of the node offset function, that is, the offset value; The known outer diameter of the drum; The drum climb-out distance compensation coefficient obtained by querying the industrial parameter database, which is used to compensate the natural inclined distance of the conveying belt after climbing out of the drum surface, and is set to 0.5 in the embodiment; ; The maximum roller diameter; The roller interference compensation coefficient obtained by querying the industrial parameter database, which is used to dynamically compensate the possible structural envelope conflict of the roller, and is set to 0.5 in the embodiment; ; The minimum safety installation distance 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 The nearest path node is offset along the set path direction based on the offset value, and the position of the node is the initial arrangement node coordinates of the roller.

[0064] The initial arrangement node coordinates of the roller are taken as the starting point, and all path nodes are sequentially traversed in the set path direction to obtain the nodes in the transition section and the nodes in the material falling section, wherein the nodes in the transition section and the nodes in the material falling section are labeled by traversing the nodes in the set path direction.

[0065] The interval correction parameters respectively belonging to the nodes in the transition section and the nodes in the blanking section in the historical node record are acquired, the product of the interval correction parameters and the preset standard arrangement interval is calculated, the transition section arrangement interval and the blanking section arrangement interval are respectively output, and the roller node arrangement is performed on the transition section and the blanking section based on the transition section arrangement interval and the blanking section arrangement interval, wherein the interval correction parameter is a parameter set by historical experience and engineering component specification, and there is a corresponding interval correction parameter for different path sections, which is used to dynamically adjust the roller arrangement interval 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 interval is a standard interval by default under general working conditions; the roller node arrangement is performed on the transition section and the blanking section respectively based on the transition section arrangement interval and the blanking section arrangement interval.

[0066] 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, if the section included angle is greater than the preset included angle threshold, a buffer section is inserted, and the roller nodes are 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 indicates that the path has a large path structure turning range; therefore, a buffer section is added between the two adjacent path sections with a 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 at equal intervals in the buffer section, so that the adjacent path sections are flexibly connected in space; all the path sections with arranged roller nodes and the remaining path sections without arranged roller nodes are connected to obtain a section adjusted conveying path.

[0067] The loading structure support enhancement mode includes:

[0068] The path node located at the midpoint of the path length in the blanking section is identified as the blanking center node, wherein the blanking center node refers to the path node at one half of the path length of the blanking section, which is the reference datum point for subsequent operations.

[0069] The conveying speed of the belt conveyor is acquired, and the material drop height at the blanking center node is detected, and the weighted sum of the conveying speed and the material drop height is obtained to obtain a first extension distance, wherein the conveying 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; the weights of the conveying speed and the material drop height are respectively set based on historical implementation experience for calculating the first extension distance.

[0070] The known industrial material dropping frequency is weighted to obtain the second type of extension distance, wherein the known industrial material dropping frequency refers to the number of material unloading times per unit of time in the industrial specification, and the work intensity weight is set based on historical implementation experience, and the known industrial material dropping frequency is weighted to obtain the second type of extension distance.

[0071] The first type of extension distance and the second type of extension distance are respectively extended forward and backward from the material dropping center node, and the front support section and the rear support section are obtained, the first type of extension distance and the second type of extension distance are both taken as the starting point and extended upstream by the first type of extension distance and extended downstream by the second type of extension distance; wherein the first type of extension distance is used to process the influence of the process of material starting to fall to impact 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 type of extension distance, and the section exists to avoid damage to the conveyor belt caused by fast transmission speed and large material falling impact; the second type of extension distance refers to the extension distance of the structural fatigue influence backward spread caused by multiple material falling, which represents the area of the subsequent path structure that may be structurally deteriorated by repeated load, and these areas need to be supported and reinforced, and therefore need to be calculated based on the known industrial material dropping frequency.

[0072] The material height difference corresponding to all path nodes in the front support section is calculated, and the mean square deviation of all material height differences is obtained, and the forward support height fluctuation value is obtained, wherein the mean square deviation of all material height differences is calculated to quantify the degree of fluctuation of the path, that is, the forward support height fluctuation value.

[0073] The contact pressure in the front support section at each material dropping 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.

[0074] The forward support height fluctuation value and the impact pressure are normalized to obtain the front support arrangement density, wherein the forward support height fluctuation value and the impact pressure are normalized and summed to obtain the front support arrangement density, which is used to reflect the arrangement density required by the carrier roller.

[0075] The product of the actual material dropping frequency and the material dropping pressure per unit of time is calculated to obtain the pressure limit value, wherein the obtained pressure limit value is used to reflect the upper limit of the fatigue bearing of the conveyor belt under long-term carrying working conditions.

[0076] If the front support arrangement density is higher than a preset density threshold, the front support section is subjected to support enhancement to obtain an enhanced front support section; if the compression 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 front support section and the enhanced rear support section are connected with the remaining sections to obtain an enhanced structure transmission path, in which 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 determined based on the front support arrangement density and the compression limit value; the enhanced section is connected with other sections that are not adjusted to obtain the enhanced structure transmission path.

[0077] The manner of supporting the front support section includes:

[0078] The normal vector offset of the continuous roller node in the front support section is detected, and a support response change sequence is constructed based on the normal vector offset, wherein all the normal vector offsets are sorted according to the arrangement order of the roller nodes in the set path direction to obtain the support response change sequence, which is used to reflect the support surface change trend.

[0079] 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 roller node is adjusted to a variable-angle 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 conveyor belt from suddenly changing direction to cause floating belt or roller side jump, etc., the roller node with a slope higher than the preset slope threshold is replaced by a variable-angle roller node, so that the angle can be dynamically adjusted according to the path shape.

[0080] Meanwhile, a buffer roller node is added between the two roller nodes closest to the blanking center node in the front support section, wherein the Euclidean distance between the roller nodes and the blanking center node in the front support section is calculated, the two roller nodes closest to the blanking center node are selected, and a plurality of buffer roller nodes are added between the two roller nodes, in which the buffer roller is selected as a rubber-coated roller or an elastic composite roller in this embodiment, which is used to absorb the impact of the blanking and block the impact wave from being transmitted back to the conveyor belt in the front support interval, wherein the specific installation number of the buffer roller node is set based on historical implementation experience; and the adjusted front support section is taken as the enhanced front support section.

[0081] The manner of supporting the rear support section includes:

[0082] Collect historical load records, identify the historical load value of each path node in the rear support section based on the historical load records, wherein the historical load records refer to the support force of the conveying belt after each material drop in the historical records of each path node in the rear support section, and the average value of the support force of each path node in a selected statistical period is calculated as the historical load value of the path node.

[0083] Extract the sub-section in the rear support section composed of any three consecutive path nodes whose historical load values are all higher than the preset bearing threshold, and replace the corresponding roller node with a heavy load roller node, wherein the sub-section composed of three consecutive path nodes is the smallest determination unit for judging overload in this embodiment. If the historical load values of all path nodes in this smallest determination unit are higher than the bearing threshold set based on historical implementation experience, it means that the conveying belt may be overloaded in this sub-section, which can easily cause fatigue or damage to the local area of the conveying belt. Therefore, the roller node installed in the above-mentioned sub-section is replaced with a heavy load roller node. In this embodiment, the heavy load roller adopts a high-strength alloy steel shaft to improve the fatigue life of the conveying belt. The adjusted rear support section is used as the enhanced rear support section.

[0084] The way of performing position clipping includes:

[0085] Calculate the distance from the tail path node of the material drop section of the enhanced structure transmission path to the path termination node, set it as the end residual length, and set the corresponding section as the tail section, wherein the end residual length refers to the distance from the last path node of the material drop 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 material drop section, but there is still a section for finishing, 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.

[0086] Divide the tail section equally and arrange roller nodes at the midpoint of each equal distance sub-section, wherein the tail section is divided into several sub-sections according to the set distance, and roller nodes are arranged at the midpoint of each equal distance sub-section to ensure continuous and uniform arrangement of roller nodes in the tail section.

[0087] If the end residual length of the tail section is greater than or equal to the 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. If the end residual length 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.

[0088] Calculate the number of additional nodes 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 function; it should be noted that the value of is greater than .

[0089] 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 nodes refer to the roller nodes that need to be added in the tail section. By compressing the distances between all roller nodes in the tail section, the additional nodes can be placed, and it is also necessary to ensure that the distances between all roller nodes remain equal after the additional nodes are added and that the last roller node is inscribed in the path termination node. This ensures the stability and load balancing of the tail section of the belt conveyor.

[0090] If the residual length of the tail section 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. If the residual length of the tail section is less than the preset end allowable distance threshold, it means that the remaining 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 based on historical implementation experience, and the roller node is used as a termination roller node. A path after the termination roller node is deleted to ensure that the termination roller node is inscribed in the termination node of the path. 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.

[0091] The space conflict judgment method includes:

[0092] The drum position coordinates in the closed structure transmission path are extracted, and the drum center axis is set based on the set path direction. A rectangular drum layout area is generated along the direction orthogonal to the drum center axis, wherein the rectangular drum layout area is generated by extending to both sides based on the drum center axis as a reference line, and the height and width are set synchronously to generate a rectangular three-dimensional area, which is the rectangular drum layout area. The set height and width are based on historical implementation experience.

[0093] Obtaining motor model parameters, generating a motor component layout area on an arbitrary side of the drum central axis of the rectangular drum layout area based on the motor model parameters, wherein the motor model parameters refer to size parameter data of the motor model, and the size parameter data of the motor model is used as a basis to select an arbitrary side of the drum central axis to generate the motor component layout area.

[0094] Determining whether there is a spatial overlap between the rectangular drum layout area and the motor component layout area, measuring the spatial intersection volume between the two areas, and in this embodiment, using three-dimensional Boolean operation to analyze the real intersection part between the rectangular drum layout area and the motor component layout area, and outputting the spatial intersection volume.

[0095] If the spatial intersection volume is greater than a preset conflict tolerance threshold, it is determined that there is a spatial conflict, wherein the spatial intersection volume is compared with the preset conflict tolerance threshold set based on historical implementation experience, and if the spatial 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 drum will be arranged symmetrically left and right, and at this time, if a motor needs to be installed, a conflict is easy to occur.

[0096] Identifying bearing seat arrangement nodes of the rectangular drum layout area, and determining the occupancy of the bearing seat arrangement nodes, wherein the positions of the bearing seat arrangement nodes in the rectangular drum layout area are identified based on historical implementation experience, and it is determined whether the positions of the bearing seat arrangement nodes have been occupied.

[0097] If there is no occupation, the component model of the spatial conflict rectangular drum layout area is moved to the side of the non-motor component layout area, and the bearing seat arrangement node on the side of the spatial conflict is moved outward along the drum central axis by a permitted offset distance, wherein the component model of the spatial conflict rectangular drum layout area refers to the component model related to the drum in the area where the rectangular drum layout area and the motor component layout area overlap; moving outward along the drum central axis by a permitted offset distance refers to translating the bearing seat arrangement node on the side of the spatial conflict along the vertical direction of the drum central 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.

[0098] 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 realize obstacle avoidance assembly between model components; and the adjusted bearing seat arrangement nodes are added to the closed structure transmission path to obtain a risk avoidance transmission path.

[0099] The way of evaluating the component combination effect includes:

[0100] The path parameters of the current risk avoidance transmission path are extracted, and the path parameters are matched with the preset component model library to 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; and the path parameters are matched with the preset component model library to screen the preliminary feasible component combination scheme from the geometric characteristics of various component models.

[0101] 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 the three-dimensional simulation is performed in the unified space coordinate system corresponding to the path to determine whether there is an abnormal situation such as insufficient layout length, vertical error exceeding the limit, angle of rotation 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.

[0102] 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 a 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.

[0103] 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, so that the splicing of the complete model is more accurate. If there is no solution with the same path length proportion, the candidate preferred solution is determined as the optimal combination solution.

[0104] The modeling and merging manner with the remaining component models includes:

[0105] The remaining components and the related components in the optimal three-dimensional transmission path are sequentially geometrically connected according to the known equipment sequence to obtain a structure frame model of the belt conveyor. Geometrically connected nodes of each component in the structure frame model are identified, and the space jump value between each pair of geometrically connected nodes is measured. If the space jump value is higher than the preset assembly error threshold, spatial correction is performed. In this embodiment, the geometrically connected nodes refer to nodes of the connection regions of two components, such as support component connection points and model boundary connection points. The space jump value refers to the offset of the spatial distance of two geometrically connected nodes compared with the spatial distance of the theoretically connected model components.

[0106] If the space jump value is higher than the preset assembly error threshold set based on the model standard specification, it indicates that the error between the two components connected is large. Based on historical implementation experience, the layout posture of the model components corresponding to the pair of geometrically connected nodes is adjusted to make the transition of each part smooth without geometric disconnection, so as to realize spatial correction.

[0107] The adjusted structure frame 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.

[0108] The embodiment starts from the path optimization aspect, obtains the optimized path through spacing adjustment, position cutting and risk avoidance on the path modeling in turn, 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, realizes the targeted optimization of the model; compared with the existing experience, the problems of the conveyor belt wear and damage of the carrier roller caused by the material falling impact are effectively relieved by identifying the path section and adjusting the layout spacing of the carrier roller nodes in the section, and the path after the carrier roller is laid is supported and enhanced, the applicability of the path modeling in the actual scene is improved; the accurate closure of the tail section carrier roller is realized by combining the path length for position cutting, the modeling error is reduced; in terms of space conflict, the position offset of the bearing seat node is adjusted by detecting the space overlap relationship between the components, the structural conflict is reduced; finally, the optimal combination scheme is screened by matching the component combination scheme and the 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.
