[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] As Figures 2 to 4 shown, in this embodiment, an anti-falling structure of a roller disassembly and assembly platform is disclosed, which includes a platform top plate 1. A plurality of rows of radial limiting devices 2 are arranged on the platform top plate 1. A limiting area 8 for placing the roller 3 is formed between two adjacent rows of the radial limiting devices 2. Axial limiting devices 5 are arranged at both ends of the limiting area 8. The axial limiting devices 5 are connected to the platform top plate 1 through telescopic adjustment assemblies 4. The axial limiting devices 5 are tightly connected to the telescopic adjustment assemblies 4 through fastening mechanisms 6. The axial limiting devices 5 are in abutting fit with the axial end faces of the rollers 3, so that the rollers 3 are fastened on the platform top plate 1 to prevent sliding.

[0030] The telescopic adjustment assembly 4 includes a support rod 4-3 and a number of support blocks 4-1. The support blocks 4-1 are fixedly connected to the platform top plate 1. The support blocks 4-1 are provided with reserved holes. The support rod 4-3 sequentially passes through the reserved holes in the support blocks 4-1, and the support rod 4-3 is slidably connected and matched with the support blocks 4-1. The support blocks 4-1 are provided with first set screws 4-2 connected by threads. The first set screws 4-2 abut against the support rod 4-3. The support blocks 4-1 are arranged in a row below the grinding roller 3. One end of the support rod 4-3 away from the platform top plate 1 is connected to the axial limiting device 5. By loosening the first set screw 4-2, the support rod 4-3 can be slid left and right on the support block 4-1, and then by sliding the axial limiting device 5 along the support rod 4-3, the position of the axial limiting device 5 can be adjusted to suit grinding rollers 3 of different length dimensions. After the position is adjusted appropriately, then tighten the first set screw 4-2 so that it abuts against the support rod 4-3 to fix the position of the support rod 4-3.

[0031] As Figures 3 to 4 shown, in this embodiment, the radial limiting device 2 is provided with multiple rows (it should be noted that in this embodiment, the direction parallel to the axis of the grinding roller 3 is defined as one row). The radial limiting device 2 is detachably connected to the grinding roller support plate 7, and the grinding roller support plate 7 is arranged on the platform top plate 1. The two outermost rows of the radial limiting device 2 are arranged obliquely with respect to the platform top plate 1, and the included angle formed between the two outermost rows of the radial limiting device 2 is an obtuse angle. Among them, the radial limiting device 2 includes a plurality of radially limiting rods 2-1 arranged in a row. The grinding roller support plate 7 is provided with round holes, and the radially limiting rods 2-1 are inserted into the round holes (attached Figure 3 is a schematic diagram after the second radially limiting rod 2-1 is pulled out to facilitate showing the installation method of the radially limiting rods 2-1). When placing the grinding roller 3, only keep the radially limiting rods 2-1 of the two outermost rows, pull out all the radially limiting rods 2-1 in the middle position, then place a grinding roller 3 and roll the grinding roller 3 against the radially limiting rods 2-1 on one side, and then insert the pulled-out radially limiting rods 2-1 into the round holes on the grinding roller support plate 7 adjacent to this grinding roller 3; then place the second grinding roller 3, roll it close to the radially limiting rods 2-1 adjacent to the first grinding roller 3, and then insert the radially limiting rods 2-1 into the round holes of the grinding roller support plate 7 adjacent to the second grinding roller 3, and so on until the grinding rollers 3 are fully placed.

[0032] In this embodiment, the radial limiting device 2 is provided with a total of three rows. Each row of the radial limiting device 2 includes two radially limiting rods 2-1, and a total of two grinding rollers 3 can be placed. The radially limiting devices 2 on the outermost sides of the two grinding rollers 3 are inclined outward so as to place the grinding rollers 3 between two adjacent rows of the radial limiting device 2.

[0033] In this embodiment, the roller support plate 7 is slidably arranged on the slide rail 1-1 by means of a chute provided at the bottom, and the slide rail 1-1 is arranged on the platform top plate 1. Among them, the slide rail 1-1 is arranged parallel to the axial direction of the roller 3.

[0034] As Figures 4 to 6 shown, in this embodiment, the axial limiting device 5 includes a limiting end 5-1, and the limiting end 5-1 abuts against the axial end face of the roller 3.

[0035] The limiting end 5-1 is arranged on the connecting end 5-2, the connecting end 5-2 is rotatably arranged on the support rod 4-3, and the connecting end 5-2 is slidably arranged on the support rod 4-3 along the axial direction of the support rod 4-3. The connecting end 5-2 is fixedly connected to the support rod 4-3 through a fastening mechanism 6.

[0036] In this embodiment, the limiting end 5-1 includes a limiting plate 5-1-1, the limiting plate 5-1-1 is arranged parallel to the axial end face of the roller 3, the limiting plate 5-1-1 is fixedly connected to the connecting rod 5-1-2, and the lower end of the connecting rod 5-1-2 is fixedly connected to the connecting end 5-2 (in the appendix Figure 6 in order to facilitate the display of the limiting plate 5-1-1, a gap is left between the limiting plate 5-1-1 and the axial end face of the roller 3).

[0037] Limit pieces 4-4 are arranged at both ends of the support rod 4-3. The limit piece 4-4 on one side can prevent the support rod 4-3 from disengaging from the support block 4-1, and the limit piece 4-4 on the other side can prevent the connecting end 5-2 from disengaging from the support rod 4-3.

[0038] As Figure 7 shown, in this embodiment, a through cavity 5-2-1 is arranged in the connecting end 5-2. The through cavity 5-2-1 is rotatably sleeved on the support rod 4-3, and the through cavity 5-2-1 can slide along the axial direction of the support rod 4-3.

[0039] As Figure 8 shown, the fastening mechanism 6 includes a second set screw 6-1 and a set screw threaded hole 6-2. The set screw threaded hole 6-2 is arranged on the connecting end 5-2, the second set screw 6-1 is threadedly connected in the set screw threaded hole 6-2, and the second set screw 6-1 abuts against the support rod 4-3. By loosening the second set screw 6-1, the connecting end 5-2 can be slid along the support rod 4-3 to adjust the position of the limiting end 5-1. After adjusting to the appropriate position, tighten the second set screw 6-1 to fix the position of the connecting end 5-2; when there is no need to limit the roller 3, by loosening the second set screw 6-1, the connecting end 5-2 can be rotated along the circumferential direction of the support rod 4-3, and the limiting end 5-1 can be placed on the platform top plate 1 or hang down naturally so as not to interfere with the placement of the roller 3.

[0040] As Figures 2 to 8As shown in the figure, the usage process of the present invention is as follows:

[0041] First, loosen all the first set screws 4-2 and the second set screws 6-1, and rotate the limiting end 5-1 to place it on the platform top plate 1 or let it hang naturally so as not to interfere with the placement of the grinding roller 3. Then install the radial limiting device 2 on the grinding roller support plate 7. After installation, place the grinding roller 3 between two adjacent rows of radial limiting devices 2. After all the grinding rollers 3 are placed, pull out the support rod 4-3 outward. After pulling it out to an appropriate length, rotate the limiting end 5-1 so that the limiting end 5-1 is located on both sides of the shaft end of the grinding roller 3. Tighten the second set screw 6-1 so that it abuts against the support rod 4-3, and then push the support rod 4-3 inward so that the limiting plate 5-1-1 abuts against the shaft end of the grinding roller 3. Finally, tighten the first set screw 4-2 to fix the support rod 4-3.

[0042] When it is necessary to temporarily remove the grinding roller 3, loosen the second set screw 6-1 on one side, move it outward and rotate the limiting end 5-1 to place it on the platform top plate 1 or let it hang naturally. Remove the grinding roller 3 for maintenance. After completion, put the grinding roller 3 back into the limiting area 8. Rotate the limiting end 5-1 again and slide the limiting end 5-1 along the support rod 4-3 so that the limiting plate 5-1-1 abuts against the shaft end of the grinding roller 3, and then tighten the second set screw 6-1 again.

[0043] The embodiments described above are only descriptions of the preferred modes of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
