[0020] like Figure 1As shown, a steel plate splicing rapid positioning device includes a base platform 1, a rolling frame 2, and a jack bracket 6. Several rollers 3 are installed on the inner wall of the rolling frame 2, and spiral top screws 4 and movable positioning plates 5 are equidistantly installed on an outer plate of the rolling frame 2. A trapezoidal support ring assembly is welded on the back of the movable positioning plate 5. After the tail end of the spiral top screw 4 is inserted into the connecting ring, the annular protrusion at the end of the spiral top screw 4 is installed. The movable spiral top screw 4 can be moved back and forth together with the movable positioning plate 5 through the rotation of the movable spiral top screw 4, and the movement of the movable positioning plate 5 is guided by the guide rod. The movable positioning plate 5 is tightly fitted and positioned with the side edge surface of the spliced steel plate 8; the jack bracket 6 is made of channel steel into a rectangle, and a long reinforcing plate 9 is welded on its top surface to increase the strength of the top frame beam. A hydraulic jack 7 is hung on the beam of the jack bracket 6, and the hydraulic jack 7 adjusts and flattens the joint surface of the spliced steel plate 8.

[0021] like Figure 2 As shown, the base platform 1 is used to place two sets of rolling frames 2, and the jack bracket 6 is placed between the two sets of rolling frames 2. The three are connected and fixed after adjusting the horizontality and straightness on site.

[0022] like Figure 2 As shown, the upper section of the column of the jack bracket 6 is hollow, which facilitates the hydraulic jack 7 to be easily placed on the top frame beam from both sides.

[0023] like Figure 3 As shown, the jack bracket 6 is made of channel steel into a rectangle, and a long reinforcing plate 9 is welded on its top surface to increase the strength of the top frame beam. The hydraulic jack 7 can move flexibly on the top frame beam; the spliced steel plate 8 is placed on the surface of the roller 3 to facilitate easy transportation and movement of the spliced steel plate 8.

[0024] like Figure 4 As shown, a screw top screw 4 and a movable positioning plate 5 are equidistantly installed on an outer plate of the rolling frame 2, a hole is drilled and tapped on an outer plate, and the screw top screw 4 is screwed into the hole, and the end of the screw top screw 4 is T-shaped.

[0025] like Figure 5 As shown, Figure 4 The AA partial view in the middle is the assembly drawing of the screw top screw 4 and the movable positioning plate 5. The trapezoidal connecting ring assembly is welded on the back of the movable positioning plate 5. The tail end of the screw top screw 4 is inserted into the connecting ring, and then the annular protrusion at the end of the screw top screw 4 is locked. After the annular protrusion is locked, the end of the screw top screw 4 becomes T-shaped.

[0026] like Figure 4 、 5 As shown, the movable positioning plate 5 can be moved forward and backward by rotating the spiral top screw 4, and the movable positioning plate is tightly fitted and positioned with the side edge surface of the spliced steel plate.

[0027] Working principle and process: Strictly follow the Figure 1 As shown in the figure, the jack bracket is placed between the two sets of rolling frames 2. After adjusting the horizontality and straightness of the three, they are connected. The spliced steel plates 8 are placed in the rolling frames 2 and are quickly transported, adjusted, and aligned by rollers 3. During operation, the screw jacks 4 and movable positioning plates 5 rotate forward until they are tightly fitted and positioned with the side edges of the spliced steel plates 8. After the operation is completed, the screw jacks 4 and movable positioning plates 5 rotate backward. On-site, the number of hydraulic jacks 7 is adjusted according to the conditions of the joints of the spliced steel plates 8 to flatten them, facilitating rapid welding of the joints and preventing welding stress and deformation.

[0028] During maintenance, since the surface of the roller 3 adopts spiral friction grooves, the sliding stability can be ensured in the process of pushing the spliced steel plate 8 to slide. However, dust is easily attached to the spiral grooves or a lot of dust and impurities are attached due to water. After the surface is cleaned, the two spliced steel plates 8 are ensured to be in a horizontal state. Therefore, before positioning the spliced steel plates 8, the external air supply pipe is opened, and a long steel plate is placed on the roller 3. The steel plate is pushed and pulled back and forth to make the roller 3 rotate back and forth. The brush bar 10 is used to brush the surface of the roller 3, and the dust brushed off is blown away by the gas sent out through the air hole through the air flow channel in the base platform 1, ensuring the cleanliness of the roller 3. In addition, the air hole sprays air to clean the brush bar 10, which can clean the impurities inside the brush bar 10 and extend the service life of the brush bar 10.
