Description

Technical Field

[0001] The present invention relates to the field of material transportation, and further relates to a three-dimensional modeling method, device, equipment and readable storage medium for a chute structure, and in particular to a three-dimensional modeling method, device, equipment and readable storage medium for an oblique transfer connection chute structure. Background Art

[0002] In bulk material transportation, a chute is a transfer device used to connect two adjacent conveyors. The transfer angle between two adjacent conveyors (such as the transfer angle of a belt conveyor) is typically determined after overall planning and is not a fixed value.

[0003] According to the transfer angle, the transfer methods of belt conveyors can generally be divided into vertical transfer (i.e., the planes where the center lines of two adjacent conveyors are perpendicular to each other), parallel transfer (i.e., the planes where the center lines of two adjacent conveyors are parallel to each other) and oblique transfer (i.e., the planes where the center lines of two adjacent conveyors are located are acute or obtuse angles). When vertical transfer and parallel transfer are performed, the outlet and inlet cross-section directions of the two adjacent conveyors used to connect the chutes are the same, and the chutes can be directly connected. In this type of transfer, the chutes connection structure is simple, and the design and installation are relatively convenient. However, when the two adjacent conveyors are transferred obliquely, the planes where the center lines of the two adjacent conveyors are located are tilted, and the chutes connecting the outlet and inlet of the two adjacent conveyors cannot be directly connected, and the design of the chutes is somewhat difficult.

[0004] At present, when two adjacent conveyors are transferred obliquely, there are two common methods for the slide pipe structure:

[0005] The first method is, Figure 1 As shown, the chute structure between the upstream conveyor 1000 and the downstream conveyor 2000 is still designed according to the conventional vertical or parallel transfer method, but since the cross-section of the guide trough opening 3000 of the downstream conveyor 2000 must be kept consistent with the cross-section of the discharge port of the upstream conveyor 1000, the size and shape of the guide trough opening 3000 of the downstream conveyor 2000 are restricted, and the passing area of ​​the guide trough opening 3000 of the downstream conveyor 2000 may not meet the required requirements.

[0006] The second method is to divide the chute structure into sections, and set a gradient structure with a cross section changing from square to round in the upper section of the chute, and one end of the square in the upper section is connected to the discharge port of the upstream conveyor 1000, and set a gradient structure with a cross section changing from round to square in the lower section, and one end of the square in the lower section is connected to the guide trough opening 3000 of the downstream conveyor 2000, that is, the upper section and the lower section are transitioned through the portion with a circular cross section. The use of this type of chute structure can make the guide trough opening 3000 of the downstream conveyor 2000 consistent with the conveying direction of the downstream conveyor 2000, and the guide trough opening 3000 of the downstream conveyor 2000 can both achieve the required passing area. However, the shape of the cross section of the chute in this method is a gradient design, which is difficult to produce and form. In addition, after the chute is formed, the difficulty of setting the outer base plate on the outside and the wear-resistant inner lining plate on the inside are greatly increased.

[0007] Regarding the problem in related technologies that it is difficult to design the chute structure connecting two adjacent conveyors when they are transferred obliquely, no effective solution has been given so far.

[0008] Therefore, the inventors, relying on their many years of experience and practice in related industries, have proposed a three-dimensional modeling method, device, equipment and readable storage medium for pipe structures to overcome the shortcomings of the prior art.

[0103] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0104] Implementation Method 1

[0105] like Figures 2 to 4 As shown, the present invention provides a three-dimensional modeling method for a slide pipe structure, which is used to construct a slide pipe connected between an upstream conveyor and a downstream conveyor. The three-dimensional modeling method for the slide pipe structure includes the following steps:

[0106] Step S101: obtaining the center point P2 of the feed port 201 of the downstream conveyor 2;

[0107] In an optional embodiment of the present invention, Figures 3 to 5 As shown, step S101 includes:

[0108] Step S1011: obtaining the center point P1 of the discharge port 101 of the upstream conveyor 1;

[0109] Step S1012: Preset the layout position of the slide pipe 3 to determine the center axis of the slide pipe 3;

[0110] Step S1013 : According to the center point P1 of the discharge port 101 of the upstream conveyor 1 and the central axis of the chute 3 , the position of the center point P2 of the feed port 201 of the downstream conveyor 2 is obtained.

[0111] Specifically, such as Figure 3 、 Figure 4 As shown, the funnel outlet position at the head of the upstream conveyor 1 can be used as the discharge port 101 of the upstream conveyor 1 in the present invention. Since the shape, size and position of the discharge port 101 of the upstream conveyor 1 are all preset, the center point P1 of the discharge port 101 of the upstream conveyor 1 can be directly obtained through the discharge port 101 of the upstream conveyor 1; the layout position of the chute 3 is preset according to actual conditions. Taking into account the impact of the material flowing down the chute 3 on the downstream conveyor 2, the inclination angle of the chute 3 to the horizontal plane is generally set to 60°; since the inclination angle of the chute 3 has been determined, the central axis of the chute 3 can be obtained, and then the intersection of the central axis of the chute 3 and the center point P1 of the discharge port 101 of the upstream conveyor 1 is taken as the starting point. The intersection of the central axis of the chute 3 and the top surface of the downstream conveyor 2 is the center point P2 of the feed port 201 of the downstream conveyor 2.

[0112] Step S201: Presetting the feed inlet 201 of the downstream conveyor 2 according to the center point of the feed inlet 201 of the downstream conveyor 2;

[0113] Further, such as Figure 3 、 Figure 4As shown, the feed inlet 201 of the downstream conveyor 2 is preset on the guide trough on the top surface of the downstream conveyor 2, with the center point P2 of the feed inlet 201 of the downstream conveyor 2. The feed inlet 201 of the downstream conveyor 2 is a rectangular opening, and the length direction of the feed inlet 201 of the downstream conveyor 2 is in the same direction as the conveying direction of the downstream conveyor 2, thereby fully utilizing the width of the guide trough of the downstream conveyor 2 and ensuring the passing area of ​​the feed inlet 201 of the downstream conveyor 2.

[0114] In an optional embodiment of the present invention, Figure 3 、 Figure 4 As shown, a three-dimensional coordinate system can be established with the center point P1 of the discharge port 101 of the upstream conveyor 1 as the origin, and the position coordinates of the center point P2 of the feed port 201 of the downstream conveyor 2 in the three-dimensional coordinate system can be obtained. Since in the three-dimensional coordinate system, the vertical distance d4 between the center point P1 of the discharge port 101 of the upstream conveyor 1 and the center point P2 of the feed port 201 of the downstream conveyor 2 can be measured (i.e., the distance d2 between the center point P1 and the center point P2 on the Z axis), and the distance d2 between the projections of the center point P1 of the discharge port 101 of the upstream conveyor 1 and the center point P2 of the feed port 201 of the downstream conveyor 2 on the same horizontal plane can also be measured, therefore, using the distance d2 between the projections of the center point P1 and the center point P2 on the same horizontal plane as the hypotenuse of the triangle, the lengths of the two right-angled sides of the triangle (i.e., d1 and d3) can be calculated respectively. The lengths of the two right-angled sides of the triangle are respectively the distance d1 between the center point P1 and the center point P2 on the X axis and the distance d3 between the center point P1 and the center point P2 on the Y axis. From the above, it can be seen that by establishing a three-dimensional coordinate system, the specific positional relationship between the center point P1 of the discharge port 101 of the upstream conveyor 1 and the center point P2 of the feed port 201 of the downstream conveyor 2 can be obtained, thereby facilitating the establishment of a three-dimensional model.

[0115] Step S301: establishing a first plane S2 parallel to the horizontal plane, where the first plane S2 is obtained by projecting the feed port 201 of the downstream conveyor 2 onto the horizontal plane;

[0116] Further, such as Figure 3 As shown, the first plane S2 is located between the discharge port 101 of the upstream conveyor 1 and the feed port 201 of the downstream conveyor 2, and is close to the feed port 201 of the downstream conveyor 2. When constructing the three-dimensional model of the chute 3, the first plane S2 is used as the boundary between the upper section 301 and the lower section 302 of the chute 3. That is, the upper section 301 of the chute 3 is constructed between the first plane S2 and the discharge port 101 of the upstream conveyor 1, and the lower section 302 of the chute 3 is constructed between the first plane S2 and the feed port 201 of the downstream conveyor 2.

[0117] Step S401: Connect the first plane S2 and the second plane S1 corresponding to the discharge port 101 of the upstream conveyor 1 to establish the upper section 301 of the chute 3;

[0118] In an optional embodiment of the present invention, Figures 6 to 9 As shown, step S401 includes:

[0119] Step S4011: respectively obtaining the positions of the vertices on the first plane S2 and the second plane S1;

[0120] Step S4012: Draw lines corresponding to the vertex positions on the first plane S2 and the vertex positions on the second plane S1;

[0121] Step S4013 : The first three-dimensional figure formed by the connecting lines is the upper section 301 of the slide pipe 3 .

[0122] In this embodiment, if Figures 7 to 9 As shown, a connection method between the vertex positions on the first plane S2 and the second plane S1 is:

[0123] First, in the counterclockwise direction, define the vertex positions on the first plane S2 as vertex A1, vertex A2, vertex A3, and vertex A4, and the vertex positions on the second plane S1 as vertex A5, vertex A6, vertex A7, and vertex A8; then, find the vertex position farthest from the center point A9 of the first plane S2 among the vertex positions on the second plane S1 (i.e., vertex A1), and then find the vertex position closest to the vertex A1 on the second plane S1 among the vertex positions on the first plane S2 (i.e., vertex A1). Vertex A5); then, using Vertex A1 and Vertex A5 as the starting points of the line connecting the second plane S1 and the first plane S2, respectively, in the counterclockwise direction described above, Vertex A1 is connected to Vertex A5, Vertex A5 to Vertex A2, Vertex A2 to Vertex A6, Vertex A6 to Vertex A3, Vertex A3 to Vertex A7, Vertex A7 to Vertex A4, Vertex A4 to Vertex A8, and Vertex A8 to Vertex A1. After each vertex is connected in sequence, the framework of the upper section 301 of the chute 3 is formed. At this point, the upper section 301 of the chute 3 is composed of eight triangles arranged along its circumference.

[0124] In this embodiment, if Figure 7 、 Figure 10 、 Figure 11 As shown, another way to connect the vertex positions on the first plane S2 and the second plane S1 is:

[0125] First, in a counterclockwise direction, define the vertex positions on the first plane S2 as vertex A1, vertex A2, vertex A3, and vertex A4, and the vertex positions on the second plane S1 as vertex A5, vertex A6, vertex A7, and vertex A8. Then, directly connect the corresponding vertices in the first plane S2 and the second plane S1, that is, connect vertex A1 with vertex A5, vertex A2 with vertex A6, vertex A3 with vertex A7, and vertex A4 with vertex A8, thereby forming the framework of the upper section 301 of the chute 3. At this time, the upper section 301 of the chute 3 is spliced ​​together by four spiral surfaces arranged along its circumference (the spiral surfaces can be obtained by twisting a quadrilateral).

[0126] Step S501: connect the upper section 301 of the chute 3 and the feed port 201 of the downstream conveyor 2 to obtain the lower section 302 of the chute 3.

[0127] In an optional embodiment of the present invention, Figure 12 、 Figure 13 As shown, step S501 includes:

[0128] Step S5011: respectively obtaining the positions of the vertices on the second plane S1 and the third plane S3, wherein the third plane S3 is the plane corresponding to the feed port 201 of the downstream conveyor 2;

[0129] Step S5012: Draw lines corresponding to the vertex positions on the second plane S1 and the vertex positions on the third plane S3;

[0130] Step S5013 : The second three-dimensional figure formed by the connecting lines is the lower section 302 of the slide pipe 3 .

[0131] Specifically, such as Figure 13 As shown, since the second plane S1 is the projection of the third plane S3 onto the horizontal plane, the vertical angles of the second plane S1 and the third plane S3 are located on the same vertical line. Lines are then drawn directly connecting the vertically opposite angles of the second plane S1 with the angles of the third plane S3 to form the framework of the lower section 302 of the chute 3. The lower section 302 of the chute 3 is formed by splicing four quadrilateral planes arranged along its circumference.

[0132] In an optional embodiment of the present invention, the preset size of the second plane S1 is smaller than the actual size of the discharge port 101 of the upstream conveyor 1, and the preset size of the third plane S3 is smaller than the actual size of the feed port 201 of the downstream conveyor 2, to reserve a wall thickness for the discharge chute 3. The wall thickness of the chute 3 can be preset to, but is not limited to, 10 mm.

[0133] In an optional embodiment of the present invention, Figure 14As shown, after step S501, the following steps are further included:

[0134] Step S601: Figure 15 As shown, a peripheral substrate 303 is constructed outside the upper section 301 of the slide pipe 3 and the lower section 302 of the slide pipe 3;

[0135] Specifically, the projections of the upper section 301 and the lower section 302 of the slide pipe 3 can be used as geometric primitives, which are stretched outward to form an outer substrate 303 surrounding the outer side of the slide pipe 3. The stretched thickness can be, but is not limited to, 10 mm.

[0136] Step S701: Figure 15 As shown, an inner lining plate 304 is constructed inside the upper section 301 of the slide pipe 3 and the lower section 302 of the slide pipe 3 .

[0137] Specifically, the projections of the upper section 301 and the lower section 302 of the chute 3 can be used as geometric primitives, which are stretched inward to form the inner lining plate 304 located inside the chute 3. The stretched thickness can be, but is not limited to, 20 mm.

[0138] Step S801: Figure 16 As shown, a connection flange 305 is constructed at the end of the chute 3, and the connection flange 305 needs to match the corresponding interface (the discharge port 101 of the upstream conveyor 1 and / or the feed port 201 of the downstream conveyor 2).

[0139] The characteristics and advantages of the three-dimensional modeling method of the slide pipe structure of the present invention are:

The three-dimensional modeling method of the chute structure is as follows: according to the center point P1 of the discharge port 101 of the upstream conveyor 1 and the preset layout position of the chute 3, the center point P2 of the feed port 201 of the downstream conveyor 2 is determined, and then the feed port 201 of the downstream conveyor 2 can be preset according to the center point P2 of the feed port 201 of the downstream conveyor 2. The first plane S2 is obtained by projecting the feed port 201 of the downstream conveyor 2 on the horizontal plane. Then, the first plane S2 is connected with the second plane S1 corresponding to the discharge port 101 of the upstream conveyor 1 to construct the upper section of the chute 3. The upper portion 301 of the chute 3 is connected to the feed port 201 of the downstream conveyor 2 to form the lower portion 302 of the chute 3, and then the upper portion 301 of the chute 3 and the lower portion 302 of the chute 3 are used to form the chute 3 as a whole. Since the discharge port 101 of the upstream conveyor 1 and the feed port 201 of the downstream conveyor 2 are both pre-set, the two ends of the constructed chute 3 can match the conveying direction of the upstream conveyor 1 and the conveying direction of the downstream conveyor 2 respectively, thereby achieving the technical effect of convenient and accurate construction of the three-dimensional model of the chute 3.

[0141] 2. The three-dimensional modeling method of the chute structure is such that the upper section 301 of the chute 3 is easy to cut and manufacture, while the lower section 302 of the chute 3 can be consistent with the running direction of the downstream conveyor 2, thereby eliminating the restriction of the guide trough of the downstream conveyor 2 on the passing area, and also making the installation of the chute 3 more convenient.

[0142] Implementation Method 2

[0143] like Figure 17 As shown, the present invention provides a three-dimensional modeling device for a slide pipe structure, which is used to construct a slide pipe connected between an upstream conveyor and a downstream conveyor. The three-dimensional modeling device for the slide pipe structure includes a position determination unit 100, a feed port preset unit 200, a plane establishment unit 300, an upper section construction unit 400, and a lower section construction unit 500, wherein:

[0144] The position determination unit 100 is used to obtain the center point P2 of the feed port 201 of the downstream conveyor 2;

[0145] The feed port preset unit 200 is used to preset the feed port 201 of the downstream conveyor 2 according to the center point P2 of the feed port 201 of the downstream conveyor 2;

[0146] Further, such as Figure 3 、 Figure 4 As shown, the feed inlet 201 of the downstream conveyor 2 is preset on the guide trough on the top surface of the downstream conveyor 2, with the center point P2 of the feed inlet 201 of the downstream conveyor 2. The feed inlet 201 of the downstream conveyor 2 is a rectangular opening, and the length direction of the feed inlet 201 of the downstream conveyor 2 is in the same direction as the conveying direction of the downstream conveyor 2, thereby fully utilizing the width of the guide trough of the downstream conveyor 2 and ensuring the passing area of ​​the feed inlet 201 of the downstream conveyor 2.

[0147] A plane establishing unit 300 is used to establish a first plane S2 parallel to the horizontal plane, where the first plane S2 is obtained by projecting the feed port 201 of the downstream conveyor 2 onto the horizontal plane;

[0148] Further, such as Figure 3 As shown, the first plane S2 is located between the discharge port 101 of the upstream conveyor 1 and the feed port 201 of the downstream conveyor 2, and is close to the feed port 201 of the downstream conveyor 2. When constructing the three-dimensional model of the chute 3, the first plane S2 is used as the boundary between the upper section 301 and the lower section 302 of the chute 3. That is, the upper section 301 of the chute 3 is constructed between the first plane S2 and the discharge port 101 of the upstream conveyor 1, and the lower section 302 of the chute 3 is constructed between the first plane S2 and the feed port 201 of the downstream conveyor 2.

[0149] The upper section construction unit 400 is used to connect the first plane S2 and the second plane S1 corresponding to the discharge port 101 of the upstream conveyor 1 to establish the upper section 301 of the chute 3;

[0150] The lower section construction unit 500 is used to connect the upper section 301 of the chute 3 with the feed port 201 of the downstream conveyor 2 to obtain the lower section 302 of the chute 3 .

[0151] In an optional embodiment of the present invention, Figure 18 As shown, the position determination unit 100 includes a first position determination module 1001, a slide pipe layout module 1002, and a second position determination module 1003, wherein:

[0152] The first position determination module 1001 is used to obtain the center point P1 of the discharge port 101 of the upstream conveyor 1;

[0153] The slide pipe layout module 1002 is used to preset the layout position of the slide pipe 3 to determine the center axis of the slide pipe 3;

[0154] The second position determination module 1003 is used to obtain the position of the center point P2 of the feed port 201 of the downstream conveyor 2 according to the center point P1 of the discharge port 101 of the upstream conveyor 1 and the central axis of the chute 3 .

[0155] Specifically, such as Figure 3 、 Figure 4 As shown, in the position determination unit 100, the funnel outlet position at the head of the upstream conveyor 1 can be used as the discharge port 101 of the upstream conveyor 1 in the present invention. Since the shape, size and position of the discharge port 101 of the upstream conveyor 1 are all preset, the center point P1 of the discharge port 101 of the upstream conveyor 1 can be directly obtained through the discharge port 101 of the upstream conveyor 1; the layout position of the chute 3 is preset according to actual conditions. Taking into account the impact of the material flowing down the chute 3 on the downstream conveyor 2, the inclination angle of the chute 3 to the horizontal plane is generally set to 60°; since the inclination angle of the chute 3 has been determined, the central axis of the chute 3 can be obtained, and then the intersection of the central axis of the chute 3 and the center point P1 of the discharge port 101 of the upstream conveyor 1 is taken as the starting point. The intersection of the central axis of the chute 3 and the top surface of the downstream conveyor 2 is the center point P2 of the feed port 201 of the downstream conveyor 2.

[0156] In an optional embodiment of the present invention, Figure 19 As shown, the upper segment construction unit 400 includes a first vertex angle acquisition module 4001, a first line connection module 4002 and an upper segment construction module 4003, wherein:

[0157] A first vertex angle obtaining module 4001 is used to obtain positions of vertex angles on the first plane S2 and the second plane S1 respectively;

[0158] The first connection module 4002 is used to connect the vertex positions on the first plane S2 with the vertex positions on the second plane S1;

[0159] The upper section construction module 4003 is used to connect the lines to form a first three-dimensional figure, which is the upper section 301 of the slide pipe 3.

[0160] Specifically, such as Figures 7 to 9 As shown, in the upper construction unit 400, the connection between the vertex positions on the first plane S2 and the second plane S1 is as follows:

[0161] First, in the counterclockwise direction, define the vertex positions on the first plane S2 as vertex A1, vertex A2, vertex A3, and vertex A4, and the vertex positions on the second plane S1 as vertex A5, vertex A6, vertex A7, and vertex A8; then, find the vertex position farthest from the center point A9 of the first plane S2 among the vertex positions on the second plane S1 (i.e., vertex A1), and then find the vertex position closest to the vertex A1 on the second plane S1 among the vertex positions on the first plane S2 (i.e., vertex A1). Vertex A5); then, using Vertex A1 and Vertex A5 as the starting points of the line connecting the second plane S1 and the first plane S2, respectively, in the counterclockwise direction described above, Vertex A1 is connected to Vertex A5, Vertex A5 to Vertex A2, Vertex A2 to Vertex A6, Vertex A6 to Vertex A3, Vertex A3 to Vertex A7, Vertex A7 to Vertex A4, Vertex A4 to Vertex A8, and Vertex A8 to Vertex A1. After each vertex is connected in sequence, the framework of the upper section 301 of the chute 3 is formed. At this point, the upper section 301 of the chute 3 is composed of eight triangles arranged along its circumference.

[0162] In an optional embodiment of the present invention, Figure 20 As shown, the lower segment construction unit 500 includes a second vertex angle acquisition module 5001, a second line connection module 5002 and a lower segment construction module 5003, wherein:

[0163] The second vertex angle obtaining module 5001 is used to obtain the positions of the vertex angles on the second plane S1 and the third plane S3, respectively. The third plane S3 is the plane corresponding to the feed port 201 of the downstream conveyor 2;

[0164] The second connection module 5002 is used to connect the vertex positions on the second plane S1 with the vertex positions on the third plane S3;

[0165] The lower section construction module 5003 is used to connect the lines to form a second three-dimensional figure, which is the lower section 302 of the slide pipe 3.

[0166] Specifically, such as Figure 13As shown, in the lower section construction unit 500, since the second plane S1 is the projection of the third plane S3 onto the horizontal plane, the vertical corners of the second plane S1 and the third plane S3 are located on the same vertical line. Lines are then drawn directly connecting the vertically opposite corners of the second plane S1 with the corners of the third plane S3 to form the framework of the lower section 302 of the chute 3. In this case, the lower section 302 of the chute 3 is formed by splicing four quadrilateral planes arranged along its circumference.

[0167] In an optional embodiment of the present invention, Figure 21 As shown, the three-dimensional modeling device of the slide pipe structure also includes a peripheral base plate building unit 600, an inner lining plate building unit 700 and a connecting flange building unit 800, wherein:

[0168] The peripheral substrate construction unit 600 is used to construct a peripheral substrate 303 outside the upper section 301 of the slide pipe 3 and the lower section 302 of the slide pipe 3; specifically, the projections of each surface of the upper section 301 of the slide pipe 3 and the lower section 302 of the slide pipe 3 can be used as geometric elements and stretched outward to form a peripheral substrate 303 surrounding the outside of the slide pipe 3.

[0169] The inner lining plate construction unit 700 is used to construct the inner lining plate 304 inside the upper section 301 of the chute 3 and the lower section 302 of the chute 3; specifically, the projections of the respective surfaces of the upper section 301 of the chute 3 and the lower section 302 of the chute 3 can be used as geometric elements and stretched inward to form the inner lining plate 304 located on the inner side of the chute 3.

[0170] The connection flange construction unit 800 is used to construct a connection flange 305 at the end of the chute 3. Specifically, the connection flange 305 needs to match the corresponding interface (the discharge port 101 of the upstream conveyor 1 and / or the feed port 201 of the downstream conveyor 2).

[0171] The characteristics and advantages of the three-dimensional modeling device of the slide pipe structure of the present invention are:

[0172] The upper part 301 of the chute 3 formed by the three-dimensional modeling device of the chute structure is convenient for cutting and manufacturing, while the lower part 302 of the chute 3 can be consistent with the running direction of the downstream conveyor 2, thereby eliminating the restriction of the guide trough of the downstream conveyor 2 on the passing area, and also making the installation of the chute 3 more convenient.
