Embodiment 1

Figure 1 is a schematic flow chart of the long-distance belt conveyor route planning method provided by the present invention. As shown in Figure 1, the long-distance belt conveyor route planning method provided by the embodiment of the present invention includes the following steps.

Step 100: According to the topographic map, generate the conveyor longitudinal section line data and the conveyor longitudinal section line CAD diagram in the Weidi software; the conveyor is a long-distance belt conveyor with horizontal turns.

This step 100 specifically includes:

Step 101: Generate the initial floor plan of the conveyor line in the Weidi software. The specific operations are as follows:

First, create a new project in Weidi software, and then use the "Main Line Plane Design" function to design the conveyor line and generate the initial floor plan of the conveyor line. Among them, save the intersection coordinate data (suffix "JD") generated in the "Main Line Plane Design" to obtain the conveyor line plane data. After performing the "Main Line Plane Design" function, run the "Design Wizard" function, and then Click "Calculate Drawing" in the "Main Line Plane Design" function to get the initial plan view of the conveyor line.

Step 102: In Weidi software, use the "3D data reading" function to convert the topographic map into a digital analog file. Among them, the terrain lines are set as constraint lines and the elevation points are set as terrain points during conversion.

Step 103: In the Weidi software, according to the digital analog file, perform the "longitudinal section interpolation" function, the "longitudinal section fitting" function, and the "longitudinal section design" function in sequence on the initial floor plan of the conveyor line to generate a belt CAD drawing of conveyor longitudinal section line with ground line, slope change point line and design line. The design line is the longitudinal section line of the conveyor.

In Figure 2, the solid line with a line width of 0.4mm is the ground line generated by "Longitudinal Section Interpolation". The solid line with a line width of 0.3mm is the variable slope point line generated by "Longitudinal Section Fitting". The solid line with the default line width is the latitude and longitude line. The software automatically calculates the "design line", and there is also a "mileage station number" at the bottom of the picture. Among them, the "slope/%" during "longitudinal section fitting" should be less than or equal to 32%.

Step 104: Use the "Longitudinal Section Design" function to perform a slope operation on the design line, generate the conveyor longitudinal section line data, and adjust the conveyor longitudinal section line CAD drawing according to the design line after the slope operation to obtain the final conveyor Machine longitudinal section line CAD drawing, the specific operation is as follows:

Use the "Longitudinal Section Design" function to perform manual slope operations on the "Design Line" generated by the "Longitudinal Section Fitting" function in step 103. Adjust the design line by adding and deleting slope points and setting the convex and concave arc radius. , until the longitudinal section line of the conveyor.

Save the longitudinal section line data file (suffix "ZDM") generated by manual grading, and save the adjusted CAD drawing of the conveyor longitudinal section line; among them, manual grading is to add and add the automatically calculated highway lines. Delete the slope change point and convert it into a standard conveyor profile line.

Step 200: Use CAD software to perform a discretization process on the CAD diagram of the conveyor longitudinal section line to obtain a CAD diagram of the conveyor longitudinal section line with bisection point marks, that is, the solid straight line segment with the default line width in Figure 2 Or the diagonal straight line segment is equally divided into 20-meter equal intervals in the horizontal direction, and the concave and convex arc segments are equally divided into 20-meter arc segments. The equal division points are retained and a discretized CAD drawing is saved.

Step 300: Use Weidi software and the conveyor longitudinal section line data to perform secondary discretization processing on the conveyor longitudinal section line CAD drawing with bisection point marks to obtain the conveyor longitudinal section after secondary discretization. Line CAD drawing, that is, in Weidi software, use the "insert slope point" function in "Longitudinal Section Design" to insert the slope changing points in the conveyor longitudinal section line data into a discretized CAD drawing At the equal division point, save the secondary discretized conveyor longitudinal section line data (suffix "ZDM"), save the secondary discretized conveyor longitudinal section line CAD drawing, and save the project.

Step 400: In the Weidi software, process the secondary discretized CAD drawing of the conveyor longitudinal section line to obtain the final plan view of the conveyor line and the final elevation view of the conveyor line. The specific operations are as follows:

Step 401: Use the "Output Vertical Curve Table" function in the "Table" module in the Weidi software to process the secondary discretized conveyor longitudinal section line CAD drawing to obtain the first vertical curve table.

Step 402: Extract and integrate station number data on the first vertical curve table derived in step 401.

For example, the station number data "K1+240.844" is organized into "1240.844".

Step 403: Find and open the file with the suffix "STA" in the project file in the background folder, replace the station data extracted in step 402 with the data with the column name "HINTCAD5.84_STA_SHUJU" in the file, and replace it with "STA" Save format.

Step 404: Import the file with the new "STA" suffix obtained in step 403 into the Weidi software through the "Project Manager" of the Weidi software, and save the project.

Step 405: Use the "side pile interpolation" function of the Weidi software to process the file with the new "STA" suffix and generate a "TXT" file. The "TXT" file contains the coordinate information of the outrigger (slope change point). , station number information and ground line elevation.

Step 406: Use the "Intersection point coordinate import/export" function in the "Data" module of the Weidi software to export a template with the suffix "JDW", and add the outriggers ( The coordinate data of the slope point) is imported into the "JDW" template and saved, and then imported into the Weidi software using the "intersection coordinate import/export" function to generate an intersection coordinate file with the "JD" suffix.

Step 407: Import the intersection coordinate file obtained in step 406 into the "Project Manager" in the Weidi software. Export the final conveyor line plan in the "Main Line Plane Design" of the Weidi software, and export the final conveyor line elevation in the "Longitudinal Section Design". By comparing the two pictures, you can find that the intersection points and elevations of the main line have been achieved. The coordinates of the legs (slope change point) in the figure correspond to each other.

So far, the above is the discretization method scheme for long-distance belt conveyor lines with horizontal turns.

Step 500: Automatically set the coordinates of the final plan view of the conveyor line and the final elevation view of the conveyor line to obtain the leg height and truss length.

The equipment list data integration method is based on the long-distance conveyor spatial turning line discretization method. By sorting out part of the data in the long-distance conveyor spatial turning line discretization method, and then adding the formula, the equipment list (outrigger height) can be quickly obtained. and truss length). The specific operations are as follows:

Step 501: According to the first vertical curve table in step 401, obtain "convex curve radius R(m)" and "concave curve radius R(m)".

Step 502: Obtain the "outrigger (slope change point) coordinates" and "ground line elevation" based on the "TXT" file generated in step 405.

Step 503: Generate a second vertical curve table based on the final plan view of the conveyor line and the final elevation view of the conveyor line, and obtain the "design line elevation", "slope" and "slope change point spacing" based on the second vertical curve table ".

Step 504: Integrate the data obtained from steps 501 to 503.

The first formula is: leg height = design line elevation - ground line elevation - shoulder pad - cement platform height;

The second formula is: truss length of convex arc segment =ASIN(SQRT(slope change point spacing^2+(slope*0.01*slope change point spacing)^2)/(2*convex curve radius))*2* Convex curve radius”;

The third formula is: truss length of concave arc segment =ASIN(SQRT(slope change point spacing^2+(slope*0.01*slope change point spacing)^2)/(2*concave curve radius))*2* concave curve radius”;

The fourth formula is: truss length of oblique line segment = SQRT ((slope*0.01)^2+1)*slope change point spacing.
