DETAILED DESCRIPTION

[0024] Embodiments of the present application are described in detail below with reference to the accompanying drawings, in which examples of the embodiments are shown. The embodiments described below are examples intended to explain the present application, and are not to be understood as limiting the present application. On the contrary, embodiments of the present application include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0025] A belt conveyor according to an embodiment of the present application for facilitating replacement of a roller is described below with reference to the accompanying drawings.

[0026] The belt conveyor provided by the embodiment of the present application is convenient to replace the roller and can be applied to the fields of metallurgy, mining, power and building materials, and is used for conveying some ores, coal, sand, blocky materials and packaged articles.

[0027] As shown in Figure 1 and Figure 4 , the belt conveyor provided by the embodiment of the present application is convenient to replace the roller and can include a conveyor 1, two support mechanisms 2 and two auxiliary support assemblies 3.

[0028] The conveyor 1 can include a rack 10 and two rollers 11, wherein the two rollers 11 are respectively detachably arranged at two ends of the rack 10, and it can be understood that the roller 11 can be fixed on the rack 10 through a threaded fastener, wherein the threaded fastener can be a bolt or a screw, for example, the threaded fastener is a bolt, and relevant personnel can remove the limiting force on the roller 11 by rotating the bolt with a wrench, thereby facilitating the disassembly of the roller 11.

[0029] In order to further clearly illustrate the above embodiment, in an embodiment of the present application, as shown in Figure 1 , the conveyor 1 can further include a plurality of idlers 12, a transmission device 13, a tensioning mechanism 14 and a conveying belt 15, wherein the plurality of idlers 12 are equidistantly arranged on the rack 10, the transmission device 13 and the tensioning mechanism 14 are respectively installed on the rack 10, the conveying belt 15 is arranged around the rack 10 once, and the conveying belt 15 is respectively attached to the roller 11, the plurality of idlers 12 and the tensioning mechanism 14.

[0030] It should be noted that the idlers 12 described in this example are used to support the conveying belt 15 and the weight of the material, the transmission device 13 is used to drive the roller 11 to drive the conveying belt 15 to rotate, and the tensioning mechanism 14 is used to adjust the tension of the conveying belt 15, wherein the idlers 12, the transmission device 13 and the tensioning mechanism 14 are all prior art, and therefore will not be described in more detail.

[0031] The two support mechanisms 2 are respectively and symmetrically arranged on the rack 10, and each support mechanism 2 is arranged adjacent to one roller 11, the support mechanism 2 is used to support the roller 11, and the two auxiliary support assemblies 3 are respectively and symmetrically arranged on one side of the rack 10, and each auxiliary support assembly 3 is arranged adjacent to one roller 11, the auxiliary support assembly 3 is used to extend the support distance of the support mechanism 2.

[0032] Specifically, referring to Figure 5In order to facilitate the initial state of the belt conveyor with replaceable roller of the embodiment of the application, in the actual operation process, the relevant personnel first release the tensioning force of the conveying belt 15 by controlling the tensioning mechanism 14, then support the roller 11 by controlling the supporting mechanism 2, then unfold the auxiliary supporting assembly 3, and finally remove the roller 11, and the roller 11 can be pulled out, which is simple and fast.

[0033] In one embodiment of the application, as shown in Figure 1 、 Figure 2 and Figure 3 , the supporting mechanism 2 can include a motor 20, a supporting plate assembly 21 and two first supporting rods 22.

[0034] The motor 20 is arranged on the rack 10, the output shaft of the motor 20 penetrates the rack 10, one end of the supporting plate assembly 21 is rotationally connected with the rack 10, and the other end of the supporting plate assembly 21 is fixedly connected with the output shaft of the motor 20. The supporting plate assembly 21 includes a supporting plate 210 and a plurality of first rollers 211. The two first supporting rods 22 are rotationally arranged on the lower surface of the supporting plate 210, and the bottom ends of the two first supporting rods 22 are in contact with the ground. The supporting plate 210 is provided with a plurality of first through grooves 212, and the first through grooves 212 are rotationally provided with a plurality of first rollers 211 arranged at equal intervals. The plurality of first rollers 211 on each supporting plate 210 are in close contact with the corresponding roller 11.

[0035] It should be noted that the supporting plate 210 described in this example is composed of two horizontal plates (not labeled in the figure) and an arc-shaped plate (not labeled in the figure). The arc-shaped plate can increase the contact area with the roller 11 and improve the stability of supporting the roller 11. The horizontal plates facilitate the installation of the first supporting rods 22. The first supporting rods 22 are connected with the supporting plate 210 through a limiting plate (not labeled in the figure), and the limiting plate is rectangular, hollow in the middle, and provided with an opening on one side and the lower surface. Specifically, referring to Figure 3 , the limiting plate is fixed to the lower surface of the supporting plate 210, and the first supporting rod 22 is hinged to the inside of the limiting plate through a pin shaft. When the first supporting rod 22 supports the supporting plate 210, the limiting plate limits the rotation angle of the first supporting rod 22, thereby improving the stability of supporting the supporting plate 210.

[0036] As a possible case, in order to improve the stability of the supporting plate assembly 21 supporting the roller 11, the motor 20 can be a self-locking motor. By controlling the self-locking of the motor 20, the angle of the supporting plate assembly 21 after rotation is fixed, thereby further improving the stability of supporting the roller 11.

[0037] As another possible case, in order to improve the stability of the first support rod 22 when supporting the supporting plate 210, the first support rod 22 can be designed as a spring table leg support.

[0038] Specifically, in actual operation, relevant personnel will control the motor 20 to drive the output shaft of the motor 20 to slowly rotate the supporting plate 210 until the supporting plate 210 is rotated to the lower side of the roller 11, the first roller 211 is attached to the roller 11, the motor 20 is turned off, and then the two first support rods 22 are unfolded to further support the supporting plate 210 and improve the stability of the supporting plate 210 when supporting the roller 11. The first roller 211 can reduce the friction between the supporting plate 210 and the roller 11, thereby facilitating the extraction of the roller 11.

[0039] Specifically, as shown in Figure 3 , the two first support rods 22 are arranged in a staggered manner on the lower surface of the supporting plate 210. The above arrangement facilitates the folding of the two first support rods 22, avoids mutual influence between them, and saves the space after folding.

[0040] Specifically, as shown in Figure 2 , the rotation direction of the first roller 211 is along the axial direction of the roller 11. The above arrangement facilitates the extraction of the roller 11 by rotating the first roller 211.

[0041] In an embodiment of the present application, as shown in Figure 1 and Figure 4 , the auxiliary support assembly 3 can include two fixed plates 30, a support plate 31, two second support rods 32, two sliding blocks 33, and a plurality of second rollers 34.

[0042] Among them, the two sides of the support plate 31 are respectively provided with symmetrical sliding grooves 310, and the sliding blocks 33 are slidably arranged in the two sliding grooves 310. One end of the two fixed plates 30 is connected with the corresponding sliding block 33 through a rotating shaft, and the other end of the two fixed plates 30 is detachably fixed on the ground. A plurality of second through grooves 311 are formed on the upper surface of the support plate 31, and a plurality of second rollers 34 are rotatably arranged in the second through grooves 311. The rotation direction of the second rollers 34 is along the axial direction of the roller 11. The two second support rods 32 are limitingly rotatably arranged (the limitingly rotatable manner can refer to the rotating arrangement of the first support rod 22) on the lower surface of the support plate 31, and the bottom ends of the two second support rods 32 are in contact with the ground.

[0043] It should be noted that the support plate 31 described in this example is an arc-shaped plate, so that the second rollers 34 can support the support plate 31 at multiple angles, thereby improving the stability of the support plate 31 when supporting the roller 11.

[0044] Specifically, in the actual operation process, when the support plate 31 needs to be unfolded, only the support plate 31 needs to be pulled up, and when the highest point is reached, the support plate 31 is rotated and the second support rod 32 is unfolded to support the support plate 31. Similarly, when folding, only the support plate 31 needs to be rotated first, and then the support plate 31 is slowly controlled to descend until it is attached to the ground, so that the folding of the support plate 31 can be completed. Not only is the operation simple, but the occupied space is also saved.

[0045] In an embodiment of the present application, as shown in Figure 4 The arrangement of the second roller 34 is the same as that of the first roller 211, which can ensure the smoothness of the movement of the roller 11.

[0046] In an embodiment of the present application, as shown in Figure 1 The height of the support plate 210 and the support plate 31 is the same, which avoids the height difference, improves the stability of the movement of the roller 11, and avoids adjusting the height of the end of the roller 11 back and forth to adapt to the height difference.

[0047] Specifically, in the actual operation process, when the roller 11 needs to be replaced or repaired, the relevant personnel first controls the motor 20 to make the output shaft of the motor 20 drive the support plate 210 to rotate slowly until the support plate 210 is rotated to the lower side of the roller 11, so that the first roller 211 is attached to the roller 11. Then the motor 20 is turned off, and the two first support rods 22 are unfolded to further support the support plate 210 and improve the stability of the support plate 210 when supporting the roller 11.

[0048] Then the support plate 31 is pulled up until the highest point, the support plate 31 is rotated and the second support rod 32 is unfolded to support the support plate 31, and finally the wrench is used to remove the restriction of the bolt on the roller 11. At this time, the roller 11 can be pulled out, and the roller 11 moves along the first roller 211 and the second roller 34 to be removed, so that the roller 11 can be repaired or replaced.

[0049] In summary, the belt conveyor with the roller convenient to replace in the embodiment of the present application is convenient to operate, greatly shortens the replacement time, ensures the production of coal in the mine, and eliminates the safety hazards in the hoisting process.
