[0002] In a coal mine underground production system, a belt conveyor is a core equipment for material transportation. Due to the complex spatial layout of a coal mine roadway, a belt conveyor system often needs to adopt a multi-stage lapping mode to complete long-distance transportation. However, the existing chute only supports a fixed angle and cannot match the complex and variable lapping requirements underground, resulting in material impact deviation and increased material scattering rate. SUMMARY

[0003] The application aims to provide a design method of an arbitrary deformation chute torsion section applicable to a coal mine underground belt conveyor, so as to solve the problem that the chute only supports a fixed angle and cannot match the complex and variable lapping requirements underground, resulting in material impact deviation and increased material scattering rate.

[0052] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0053] In the coal mine underground production system, belt conveyor is the core equipment of material transportation. Due to the complex spatial layout of coal mine roadway, the multi-stage overlapping method is often used for long-distance transportation of belt conveyor system. In actual application, there are mainly two basic forms of overlapping of upper and lower belt conveyors: flat crossing and overpass crossing. Among them, flat crossing refers to the intersection of upper and lower conveyors at a certain angle in the same horizontal plane. Overpass crossing refers to the cross arrangement of conveyors at different heights.

[0054] However, the spatial limitation of coal mine roadway often leads to various complex situations of conveyor installation position, including:

[0055] Parallel arrangement: the axes of upper and lower conveyors are parallel but there is a height difference.

[0056] Vertical arrangement: the axes of conveyors cross at 90°.

[0057] Oblique arrangement: the axes of conveyors cross at an arbitrary angle.

[0058] Therefore, the current chute design has the following technical defects:

[0059] (1) Fixed structure is adopted, which cannot adapt to different overlapping angle requirements, leading to problems such as material scattering and blockage during material transfer. Specifically, since the traditional chute adopts overall welding or simple segmented design, the torsion section can only be realized through fixed angle bends (such as 30°, 45°, 60°, etc. precast angle). The angle increment of fixed bend is usually 15°, and the overlapping angle of underground belt conveyor may be any value (such as 37°, 52°, etc.), which will cause material impact angle deviation, aggravate wear and tear and scattering (the actual scattering rate increases by 40%). And the overall welded structure cannot be adjusted, once the installation is wrong or the working condition changes, the whole must be replaced, which is costly (customization cost increases by 3-5 times).

[0060] (2) The existing torsion chute is mostly customized for specific angles, with poor universality, poor precision and difficult installation adjustment in underground. Specifically, the traditional method relies on empirical formula or simplified model to calculate the size of torsion section, which leads to large angle error (more than ±5°), affecting the material trajectory; the steel plate is not accurate, which needs to be cut and adjusted on site (the installation time is prolonged by 2-3 times), which cannot guarantee the spatial fitting precision of 8 steel plates.

[0061] (3) Lack of standardized design method, each time a different overlapping situation is encountered, it needs to be redesigned and manufactured, which is low in efficiency;

[0062] (4) The sealing performance of the joint between the chute and the conveyor is poor, and dust pollution is easy to occur. Specifically, the traditional chute adopts flange connection + rubber gasket at the torsion position, but the space of the torsion working condition needs to be shaped spliced, and the ordinary flange cannot adapt to the non-standard angle (for example, the flange surface cannot be completely matched when the joint is 52°). Moreover, the rubber gasket is insufficient in expansion ratio (<20%) under torsion deformation, and is easy to tear or age. At the same time, after splicing, the number of joints is large (for example, 3-4 segments are needed for 30° torsion), which increases the dust leakage points (leakage rate > 8%); uneven bolt fastening force can cause steel plate deformation, and long-term operation can cause sealing failure, resulting in dust pollution.

[0063] To overcome the above problems, the application provides a design method of an arbitrary deformation chute torsion section applicable to a coal mine underground belt conveyor, which realizes efficient and reliable joint of the coal mine underground belt conveyor system.

[0064] Figure 1 A flowchart of the design method of the arbitrary deformation chute torsion section applicable to the coal mine underground belt conveyor provided by the example embodiment of the application is shown. As shown in Figure 1 The method provided by the embodiment of the application includes the following steps:

[0065] Step 110: Obtain the joint parameters of the upper and lower conveyors and the size parameters of the chute. The joint parameters of the upper and lower conveyors can include the projection angle of the center lines of the upper and lower conveyors in the horizontal plane and the vertical height difference of the upper and lower conveyors. The size parameters of the chute can include the height of the torsion section of the chute, the upper opening size of the chute, and the lower opening size of the chute.

[0066] For example, the joint parameters of the upper and lower conveyors and the size parameters of the chute can be measured by using a laser range finder or a total station.

[0067] Step 120: Based on the joint parameters of the upper and lower conveyors and the size parameters of the chute, the projections of the upper and lower openings of the chute in the horizontal plane are segmented to obtain the projections of multiple triangular torsion structures in the horizontal plane. The projections of the multiple triangular torsion structures in the horizontal plane can be directly determined by the projection method, which is convenient for subsequent division of the chute torsion section.

[0068] Step 130: Based on the joint parameters of the upper and lower conveyors and the size parameters of the chute, the projection parameters of the multiple triangular torsion structures are determined. It should be understood that the projection parameters here refer to the size of the triangular projection in the horizontal plane.

[0069] Step 140: Based on the projection parameters of the multiple triangular torsion structures and the size parameters of the chute, the real parameters of the multiple triangular torsion structures are determined. It should be understood that the real parameters here refer to the actual size of the multiple triangular torsion structures.

[0070] Step 150: determining the twist segment parameters of the chute based on the real parameters of the multi-piece triangular twist structure. After determining the real parameters of the multi-piece triangular twist structure, only welding or bolting connection of the multi-piece triangular twist structure and the related structure is needed to obtain the twist segment of the chute.

[0071] In the method for designing the twist segment of the arbitrary deformation chute of the belt conveyor in the coal mine provided in the application, the overlap parameters of the upper belt conveyor and the lower belt conveyor and the size parameters of the chute are obtained, the projection of the upper opening and the lower opening of the chute in the horizontal plane is segmented based on the parameters, the projection of the multi-piece triangular twist structure in the horizontal plane is obtained, the projection parameters of the multi-piece triangular twist structure are determined based on the overlap parameters of the upper belt conveyor and the lower belt conveyor and the size parameters of the chute, the real parameters of the multi-piece triangular twist structure are determined based on the projection parameters of the multi-piece triangular twist structure and the size parameters of the chute, and finally the twist segment parameters of the chute are determined based on the real parameters of the multi-piece triangular twist structure, the design of the twist segment of the chute is completed, and the complex and variable angle overlap requirements in the coal mine are matched.

[0072] It can be seen that, in the application, the twist segment of the chute is designed based on the overlap parameters of the upper belt conveyor and the lower belt conveyor (the complex and variable angle overlap requirements in the coal mine) and the size parameters of the chute, so that the chute can realize the overlap at different angles, thereby avoiding the phenomenon of material impact deviation and reducing the material scattering rate.

[0073] In some optional modes, Figure 2 a top view of the upper belt conveyor and the lower belt conveyor provided in the example embodiment of the application is shown, Figure 3 a front view of the chute provided in the example embodiment of the application is shown, Figure 4 a left view of the chute provided in the example embodiment of the application is shown, Figure 5 a schematic view of the projection of the upper opening and the lower opening in the horizontal plane provided in the example embodiment of the application is shown. As Figures 2-5 shown, the segmentation of the projection of the upper opening 31 and the lower opening 32 of the chute 3 in the horizontal plane based on the overlap parameters of the upper belt conveyor 1 and the lower belt conveyor 2 further can include: first segmenting the projection of the upper opening 31 and the lower opening 32 of the chute 3 in the horizontal plane based on the projection angle of the center lines of the upper belt conveyor 1 and the lower belt conveyor 2 in the horizontal plane and the projection of the upper opening 31 and the lower opening 32 of the chute 3 in the horizontal plane, to obtain the projection of the multi-piece triangular twist structure in the horizontal plane.

[0074] In some optional modes, as Figures 2-5As shown, the above determining the projection parameters of the plurality of triangular twist structures based on the overlapping parameters of the upper and lower conveyors 1 and 2 and the size parameters of the chute 3 can further include: modeling the chute 3 based on the overlapping parameters of the upper and lower conveyors 1 and 2 and the size parameters of the chute 3 to obtain a chute 3 model, and then determining the projection parameters of the plurality of triangular twist structures based on the chute 3 model and the overlapping parameters of the upper and lower conveyors 1 and 2 and the size parameters of the chute 3.

[0075] As an example, the modeling software such as CAD software can be used to model the projections of the upper and lower openings of the chute on the horizontal plane and input the relevant size parameters to obtain the chute model. In this case, the projection parameters of the plurality of triangular twist structures can be directly read in the modeling software.

[0076] In some optional manners, as shown in Figures 2-5 As shown, the above determining the real parameters of the plurality of triangular twist structures based on the projection parameters of the plurality of triangular twist structures and the size parameters of the chute 3 can further include: determining the real parameters of the plurality of triangular twist structures based on the projection parameters of the plurality of triangular twist structures and the height of the twist segment 33 of the chute 3. Here, the real parameters of each triangular twist structure can be determined based on the Pythagorean theorem.

[0077] As an example, as shown in Figures 2-5 As shown, when the overlapping angle (the included angle of the center lines of the upper and lower conveyors 1 and 2 on the horizontal plane) θ = 60°, the vertical height difference H1 of the upper and lower conveyors 1 and 2 = 6000mm, the height H2 of the twist segment of the chute 3 = 500mm, the width B1 of the upper opening 31 of the chute 3 (the width of the upper conveyor belt) = 1400mm, the height h1 of the chute 3 at the upper opening 31 = 3550mm, the width B2 of the lower opening 32 of the chute 3 (the width of the lower conveyor belt) = 1400mm, and the height h2 of the chute 3 at the lower opening 32 = 1913mm are determined, according to the overlapping angle and the projections of the upper and lower openings 31 and 32 of the chute 3 on the horizontal plane, the twist segment of the chute 3 can be decomposed into 8 triangular steel plates, each steel plate connects the corresponding edges of the upper and lower openings 31 and 32, and the 8 triangular steel plates include four S1 steel plates and four S2 steel plates.

[0078] Figure 6 As shown in the schematic diagram of the real parameter determination of the triangular S1 provided by the example embodiment of the present application Figure 1 , Figure 7 As shown in the schematic diagram of the real parameter determination of the triangular S1 provided by the example embodiment of the present application Figure 2 , Figure 8 As shown in the schematic diagram of the real parameter determination of the triangular S1 provided by the example embodiment of the present application Figure 3 .Figures 6-8 As shown, one side length C1 of triangle S1 can be determined by modeling the upper opening 31 and the lower opening 32 of the chute 3 in the CAD software: C1 = a1 + H2, where a1 is the length of the upper opening 31 of the chute 3, and H2 is the height of the lower opening 32 of the chute 3. Figure 6 It is known that a1 = 609 mm, the height H2 of the upper and lower openings 32 of the twisting section is 500 mm, and C1 = 788 mm can be known by the Pythagorean theorem or the CAD model. Similarly, a2 = 729 mm, another side length C2 of triangle S1 = 884 mm, and another side length C3 = B1 = 1400 mm.

[0079] Figure 9 A schematic diagram of determining the real parameters of triangle S2 provided by the example embodiments of the present application is shown. As shown, Figure 9 a3 = 2078 can be determined using the above method, then one side length C4 of triangle S2 = C2 = 884 mm, another side length C5 = 2500 mm, and another side length C6 = 2137 mm. Based on this, after determining the real size of triangle S1 and triangle S2, the required steel plates can be obtained according to the real size, and the twisting section 33 of the chute 3 of the present application can be obtained by welding or bolt connection. It should be noted that when cutting, 10-20 mm of welding / bolt connection allowance can be reserved at the edge of each triangular steel plate. At the same time, by sealing treatment with rubber pads and polyurethane sealant at the joints, dust leakage can be prevented.

[0080] In summary, the method provided by the example embodiments of the present application realizes continuous adjustment of any angle in the range of 0°-90° with an adjustment accuracy of ±0.5° by parameterizing steel plate splicing design and accurately calculating the size of each component based on spatial geometric algorithm, completely solves the angle adaptation problem, can flexibly cope with various complex lap joint working conditions, and significantly improves the adaptability and reliability of the coal mine transportation system.

[0081] As shown, Figures 2-5 The example embodiments of the present application also provide an arbitrary deformation chute suitable for a coal mine underground belt conveyor, which comprises:

[0082] an upper chute structure 34; and

[0083] a lower chute structure 35, the lower chute structure 35 comprises a material receiving part 351 and a twisting section 33 connected to each other, the material receiving part 351 is connected to the upper chute structure 34 through a crusher 36, and the twisting section 33 is designed by the arbitrary deformation chute twisting section design method suitable for a coal mine underground belt conveyor provided by the present application.

[0084] In some optional modes, the above-mentioned twisting section 33 comprises a plurality of triangular twisting structures, rubber pads and polyurethane sealant are arranged at the joints of adjacent two triangular twisting structures and the connection between the twisting section 33 and the material receiving part 351 to prevent dust leakage.

[0085] Compared with the prior art, the beneficial effects of the arbitrary deformation chute for the coal mine underground belt conveyor provided by the embodiments of the application are the same as those of the design method of the arbitrary deformation chute torsion section for the coal mine underground belt conveyor, and will not be repeated here.
