Vertical plates are connected to the horizontal plate at intervals, and fastening bolts are screwed onto the vertical plates. Adjusting the fastening bolts allows ribs of different sizes and shapes to be clamped on the vertical plates. Spring positioning pins are connected to the support platform, and the screws screwed onto the horizontal plates are inserted into the spring positioning pins so that the horizontal plates do not rotate during rib grinding.

[0011] Furthermore, multiple first connecting rods are connected at equal intervals to the support platform to ensure that the sealed bearing is stably connected to the support platform.

[0012] Furthermore, the inner ring of the sealed bearing is vertically connected to multiple second connecting rods, all of which are connected to a horizontal plate.

[0013] Furthermore, multiple second connecting rods are connected at equal intervals to the inner ring of the sealed bearing to ensure stable rotation of the horizontal plate.

For example, in the claims, any of the claimed embodiments can be used in any combination.

[0026] The following is a reference to the appendix. Figure 1 To be continued Figure 3 This invention describes a rotatable rib grinding auxiliary device.

[0027] like Figure 1 As shown, the rotatable rib grinding auxiliary device of this utility model includes a support platform 1 and a sealed bearing 2. The outer ring of the sealed bearing 2 is connected to the support platform 1, and the inner ring of the sealed bearing 2 is connected to a horizontal plate 3, so that the horizontal plate 3 can rotate relative to the support platform 1. Vertical plates are connected to the horizontal plate 3 at intervals, and fastening bolts 6 are screwed onto the vertical plates. Adjusting the fastening bolts 6 allows ribs of different sizes and shapes to be clamped on the vertical plates. A spring positioning pin 7 is connected to the support platform 1, and the screws 8 screwed onto the horizontal plate 33 are inserted into the spring positioning pin 7 so that the horizontal plate 3 does not rotate during rib grinding.

[0028] By connecting and fastening bolts 6 to the vertical plate, stiffening plates of various sizes are secured to the horizontal plate 3. The horizontal plate 3 is connected to the support platform 1 via a sealed bearing 2, allowing the horizontal plate 3 to rotate. This significantly reduces the number of times the stiffening plate position needs to be adjusted. During stiffening plate grinding, screws 8 screwed to the horizontal plate 3 are inserted into spring positioning pins 7 to keep the horizontal plate 3 stationary. This application offers flexible and convenient operation, meets the fastening requirements of stiffening plates of various sizes, ensures the safety of operators and tools, improves construction efficiency, and reduces the labor intensity of operators.

[0029] Furthermore, such as Figure 1 As shown, the upright plate includes a first upright plate 4 and a second upright plate 5. The first upright plate 4 and the second upright plate 5 are vertically connected to the horizontal plate 3. Fastening bolts 6 are screwed onto the first upright plate 4. Multiple fastening bolts 6 are screwed onto the first upright plate 4 at intervals. Individual or simultaneous adjustment of multiple fastening bolts 6 can be used to clamp ribs of different sizes and shapes between the first upright plate 4 and the second upright plate 5.

[0030] In this embodiment, preferably, the first upright plate 4 and the second upright plate 5 have the same shape and size. The first upright plate 4 and the second upright plate 5 are both vertically welded to the horizontal plate 3. Multiple screw holes are spaced apart along the length of the first upright plate 4, and fastening bolts 6 are screwed into the screw holes.

[0031] When the fastening bolts 6 are rotated simultaneously, the reinforcing ribs placed between the first upright plate 4 and the second upright plate 5 are fixedly clamped between the first upright plate 4 and the second upright plate 5. When the reinforcing ribs are irregularly shaped, the thread size of each fastening bolt 6 is changed so that reinforcing ribs of different shapes can be clamped between the first upright plate 4 and the second upright plate 5.

[0032] Furthermore, such as Figure 1 and Figure 2 As shown, multiple first connecting rods 9 are vertically connected to the support platform 1, and all of the multiple first connecting rods 9 are connected to the outer ring of the sealed bearing 2; the multiple first connecting rods 9 are connected to the support platform 1 at equal intervals so that the sealed bearing 2 is stably connected to the support platform 1.

[0033] The inner ring of the sealed bearing 2 is vertically connected to a plurality of second connecting rods 10, and the plurality of second connecting rods 10 are all connected to the horizontal plate 3; the plurality of second connecting rods 10 are connected to the inner ring of the sealed bearing 2 at equal intervals so as to make the horizontal plate 3 rotate stably.

[0034] In this embodiment, preferably, three first connecting rods 9 are vertically welded to the center of the support platform 1. The three first connecting rods 9 are arranged in an equilateral triangle. The outer ring of the sealing bearing 2 is welded to the three first connecting rods 9, so that the sealing bearing 2 is stably set on the support platform 1.

[0035] Three second connecting rods 10 are vertically welded to the inner ring of the sealed bearing 2. The three second connecting rods 10 are arranged in an equilateral triangle. The three second connecting rods 10 have the same height. The ends of the three second connecting rods 10 away from the inner ring of the sealed bearing 2 are welded to the horizontal plate 3, thereby enabling the horizontal plate 3 to rotate horizontally, which is convenient for grinding the rib plate.

[0036] Furthermore, such as Figure 1 and Figure 3 As shown, a positioning hole is provided on the horizontal plate 3, and the screw 8 passes through the positioning hole and is inserted into the spring positioning pin 7 so that the horizontal plate 3 does not rotate; the spring positioning pin 7 is vertically welded to the support platform 1; the support platform 1 is connected to multiple support legs 11 so that the support platform 1 is away from the ground.

[0037] In this embodiment, preferably, positioning holes are symmetrically provided on the horizontal plate 3, and spring positioning pins 7 are welded on the support platform 1. When it is necessary to grind the rib plate, screws 8 are inserted into the positioning holes, and the screws 8 are inserted into the spring positioning pins 7 to fix the horizontal plate 3, ensuring that the horizontal plate 3 does not rotate when grinding the rib plate. The support platform 1 is connected to multiple support legs 11 so that the support platform is at least 450mm off the ground.

[0038] The working principle of the rotatable rib grinding auxiliary device in this utility model is as follows:

[0039] Place the stiffening plate between the first vertical plate 4 and the second vertical plate 5, and fix the stiffening plate between the first vertical plate 4 and the second vertical plate 5 by tightening the bolts 6. Rotate the horizontal plate 3 to grind the designated position of the stiffening plate. When grinding the stiffening plate, the screw 8 passes through the positioning hole of the horizontal plate 3 and inserts into the spring positioning pin 7 to keep the stiffening plate stationary.

[0040] Based on a rotatable rib grinding auxiliary device, this utility model uses fastening bolts 6 connected to the first vertical plate 4 to secure ribs of various sizes between the first vertical plate 4 and the second horizontal plate 5. The horizontal plate 3 is connected to the support platform 1 via a sealed bearing 2, allowing the horizontal plate 3 to rotate. This significantly reduces the number of times the rib position needs to be adjusted. During rib grinding, the screws 8 screwed to the horizontal plate 3 are inserted into the spring positioning pins 7 to keep the horizontal plate 3 stationary. This application offers flexible and convenient operation, meets the fastening requirements of ribs of various sizes, ensures the safety of operators and tools, improves construction efficiency, and reduces the labor intensity of operators.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model.
