Detailed Implementation

[0027] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] like Figures 2 to 4 As shown, this embodiment discloses a fall prevention structure for a grinding roller assembly / disassembly platform, including a platform top plate 1. Multiple rows of radial limiting devices 2 are arranged on the platform top plate 1, forming a limiting area 8 for placing the grinding roller 3 between adjacent rows of radial limiting devices 2. Axial limiting devices 5 are provided at both ends of the limiting area 8, and the axial limiting devices 5 are connected to the platform top plate 1 via a telescopic adjustment assembly 4. The axial limiting devices 5 are fastened to the telescopic adjustment assembly 4 via a fastening mechanism 6, and the axial limiting devices 5 abut against the shaft end face of the grinding roller 3, thus securing the grinding roller 3 to the platform top plate 1 and preventing slippage.

[0029] The telescopic adjustment assembly 4 includes a support rod 4-3 and several support blocks 4-1. The support blocks 4-1 are fixedly connected to the platform top plate 1. Each support block 4-1 has a pre-drilled hole, through which the support rod 4-3 passes. The support rod 4-3 and the support block 4-1 are slidably connected. Each support block 4-1 has a threaded first set screw 4-2, which abuts against the support rod 4-3. The support blocks 4-1 are arranged in a row below the grinding roller 3. The end of the support rod 4-3 furthest 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. Simultaneously, the axial limiting device 5 can be slid along the support rod 4-3 to adjust its position to accommodate grinding rollers 3 of different lengths. After adjusting the position, the first set screw 4-2 is tightened to abut against the support rod 4-3, thus fixing the position of the support rod 4-3.

[0030] like Figures 3 to 4 As shown, in this embodiment, the radial limiting device 2 is arranged in multiple rows (it should be noted that in this embodiment, a row is defined in the direction parallel to the axial direction of the grinding roller 3). The radial limiting device 2 is detachably connected to the grinding roller support plate 7, which is set on the platform top plate 1. The outermost two rows of radial limiting devices 2 are arranged at an angle to the platform top plate 1, and the angle formed between the outermost two rows of radial limiting devices 2 is an obtuse angle. The radial limiting device 2 includes multiple radial limiting rods 2-1 arranged in a row. The grinding roller support plate 7 has a circular hole, and the radial limiting rods 2-1 are inserted into the circular hole (see attached diagram). Figure 3 This diagram illustrates the installation method of the radial limit rod 2-1 after it has been removed. When placing the grinding roller 3, only the outermost two rows of radial limit rods 2-1 are retained. All the radial limit rods 2-1 in the middle position are removed. Then, a grinding roller 3 is placed in and rolled to rest against one of the radial limit rods 2-1. The removed radial limit rods 2-1 are then inserted into the round holes on the grinding roller support plate 7 adjacent to the grinding roller 3. The second grinding roller 3 is then placed in and rolled to the radial limit rod 2-1 adjacent to the first grinding roller 3. The radial limit rod 2-1 is then inserted into the round hole on the grinding roller support plate 7 adjacent to the second grinding roller 3, and so on, until all grinding rollers 3 are placed.

[0031] In this embodiment, the radial limiting device 2 is arranged in three rows. Each row of radial limiting device 2 includes two radial limiting rods 2-1, which can accommodate two grinding rollers 3. The outermost radial limiting device 2 of the two grinding rollers 3 is inclined outward so as to place the grinding rollers 3 between two adjacent rows of radial limiting devices 2.

[0032] In this embodiment, the grinding roller support plate 7 is slidably mounted on the slide rail 1-1 via a groove at its bottom, and the slide rail 1-1 is mounted on the platform top plate 1. The slide rail 1-1 is arranged parallel to the axial direction of the grinding roller 3.

[0033] like Figures 4 to 6 As shown, in this embodiment, the axial limiting device 5 includes a limiting end 5-1, which abuts against the shaft end face of the grinding roller 3.

[0034] The limiting end 5-1 is set on the connecting end 5-2, the connecting end 5-2 is rotatably set on the support rod 4-3, and the connecting end 5-2 is slidably set on the support rod 4-3 along the axial direction of the support rod 4-3. The connecting end 5-2 is fastened to the support rod 4-3 through the fastening mechanism 6.

[0035] In this embodiment, the limiting end 5-1 includes a limiting plate 5-1-1, which is arranged parallel to the shaft end face of the grinding 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 (see attached diagram). Figure 6 To facilitate the display of the limiting plate 5-1-1, a gap was left between the limiting plate 5-1-1 and the shaft end face of the grinding roller 3.

[0036] Limiting pieces 4-4 are provided at both ends of the support rod 4-3. The limiting piece 4-4 on one side can prevent the support rod 4-3 from coming off the support block 4-1, and the limiting piece 4-4 on the other side can prevent the connecting end 5-2 from coming off the support rod 4-3.

[0037] like Figure 7 As shown, in this embodiment, a through cavity 5-2-1 is provided inside the connecting end 5-2. The through cavity 5-2-1 is rotatably sleeved on the support rod 4-3 and can slide along the axial direction of the support rod 4-3.

[0038] like Figure 8 As 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 located on the connecting end 5-2, and the second set screw 6-1 is threaded into the set screw threaded hole 6-2, with the second set screw 6-1 pressing tightly against the support rod 4-3. Loosening the second set screw 6-1 allows the connecting end 5-2 to slide along the support rod 4-3 to adjust the position of the limiting end 5-1. After adjusting to the appropriate position, tightening the second set screw 6-1 fixes the position of the connecting end 5-2. When it is not necessary to limit the grinding roller 3, loosening the second set screw 6-1 allows the connecting end 5-2 to rotate circumferentially along the support rod 4-3, placing the limiting end 5-1 on the platform top plate 1 or letting it hang naturally, so as not to interfere with the insertion of the grinding roller 3.

[0039] like Figures 2 to 8As shown, the usage process of this utility model is as follows:

[0040] First, loosen the first set screw 4-2 and the second set screw 6-1, and rotate the limiting end 5-1 to place it on the platform top plate 1 or let it hang down 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 the support rod 4-3 outward. After pulling it out to a suitable 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 is pressed tightly against the support rod 4-3. Then push the support rod 4-3 inward so that the limiting plate 5-1-1 is pressed against the shaft end of the grinding roller 3. Finally, tighten the first set screw 4-2 to fix the support rod 4-3.

[0041] If 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, place it on the platform top plate 1 or let it hang down naturally, remove the grinding roller 3 for maintenance, and 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 tighten the second set screw 6-1 again.

[0042] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
