[0014] The present invention will be further described below by way of examples with reference to the accompanying drawings.

[0015] See attached Figure 1-3A cold rolling pickling line squeeze roller changing and alignment device comprises a suspension beam 1, an end surface line sinker 2, a transverse line sinker 3, a vertical line sinker 4 and a frame 6, wherein the suspension beam 1 is located above the squeeze roller, and the suspension beam 1 is slidably connected to the frame 6, the end surface line sinker 2 matches with the end surface of the roller 61 to be aligned, and the upper end of the end surface line sinker 2 is fixed on a sliding block 14, and the sliding block 14 is slidably connected to the suspension beam 1; the transverse line sinker 3 matches with the roller 61 to be aligned and the adjacent roller 62; the middle of the vertical line sinker 4 is suspended on the suspension beam 1, and the vertical line sinker 4 matches with the roller body of the roller 61 to be aligned; the lower end of the end surface line sinker 2, the two ends of the transverse line sinker 3 and the two ends of the vertical line sinker 4 are respectively provided with a sinker 42.

[0016] In this embodiment, refer to the attached Figure 1-3 The squeeze roller changing and aligning device comprises a suspension beam 1, an end surface plumb line 2, a horizontal plumb line 3 and a vertical plumb line 4. The suspension beam 1 is slidably connected to the frame 6 along the direction of the frame 6, and the suspension beam 1 is located above the roller 61 to be aligned; the end surface plumb line 2 is connected to the outer end of the suspension beam 1, and is used to fit on the end surface of the roller 61 to be aligned, and the end surface plumb line 2 can align the end surfaces of the upper and lower rollers 61 to be aligned, so that the two end surfaces remain vertically flush; the horizontal plumb line 3 is mounted on the roller 61 to be aligned and the two adjacent rollers 62, and can adjust and align the height of the roller 61 to be aligned; the middle part of the vertical plumb line 4 is connected to the suspension beam 1 through a connecting line 41, and the vertical plumb line 4 is mounted on the upper and lower rollers 61 to be aligned, so that the two rollers 61 to be aligned can be vertically aligned; wherein, the lower end of the end surface plumb line 2, the two ends of the horizontal plumb line 3 and the two ends of the vertical plumb line 4 are respectively provided with plumb bodies 42.

[0017] When not in use, the end line sinker 2, the vertical line sinker 4 and the horizontal line sinker 3 are respectively wound around or placed on the suspension beam 1. The position of the suspension beam 1 on the frame 6 can be changed by moving the suspension beam 1 to avoid interference with the normal operation of the squeeze roller.

[0018] When alignment is required, the transverse plumb line 3 is placed on the two adjacent rollers 62 on both sides of the roller 61 to be aligned. Under the action of the plumb body 42, the transverse plumb line 3 extends horizontally between the two adjacent rollers 62, and the peripheral wall of the roller 61 to be aligned is adjusted to a position that fits under the transverse plumb line 3, to ensure that the roller 61 to be aligned and the adjacent roller 62 are at the same horizontal height; then, the vertical plumb line 4 is placed on the upper and lower rollers 61 to be aligned, so that the two side walls of the roller 61 to be aligned located at the bottom are respectively in contact with the inner side of the vertical plumb line 4, to achieve vertical alignment of the upper and lower rollers 61 to be aligned; finally, the end plumb line 2 is used to align the outer end faces of the upper and lower rollers 61 to be aligned, to ensure that the outer end faces of the upper and lower rollers 61 to be aligned are in the same vertical plane. At this point, the alignment of the relative positions of the two rollers 61 to be aligned is completed, which helps to improve the centering accuracy of the rollers 61 to be aligned during installation.

[0019] See also Figures 1 to 3 In order to realize the position change of the suspension beam 1, a slide rail 5 is set on the frame 6. The slide rail 5 extends horizontally along the direction of the frame 6. The end of the suspension beam 1 is slidably connected to the slide rail 5 through a slide seat 11, and can be conveniently adjusted according to the installation position of the roller 61 to be aligned.

[0020] See also Figures 1 to 3 The slide rail 5 is threadedly connected with a locking bolt 51 that passes through the side wall of the slide rail 5. When the suspension beam 1 moves to a desired position along the slide rail 5, the locking bolt 51 can be used to lock it to ensure the stability of the position of the suspension beam 1.

[0021] See also Figures 1 to 3 When the end surface plumb bob 2 is used to align the outer end surfaces of the two rollers 61 to be aligned, in order to meet the alignment requirements of rollers 61 of various specifications to be aligned, a sliding groove 13 extending along its extension direction, that is, the axial direction of the roller 61 to be aligned is provided on the suspension beam 1. The upper end of the end surface plumb bob 2 is connected to a sliding block 14 slidably connected to the sliding groove 13. By adjusting the position of the sliding block 14 in the sliding groove 13, the end surface plumb bob 2 is attached to the outer end surface of the roller 61 to be aligned, ensuring the effective alignment of the end surfaces of the two rollers 61 to be aligned, which helps to improve the alignment efficiency and the practicality of the alignment device.

[0022] See also Figures 1 to 3 , the vertical plumb bob 4 is located between the end plumb bob 2 and the transverse plumb 3, the end plumb 2 is arranged near the outermost end of the suspension beam 1, the vertical plumb 4 is arranged adjacent to the end plumb 2, and the vertical plumb 4 is connected to the bottom of the suspension beam 1 through the connecting line 41, the position of the transverse plumb 3 is relatively free, and it can be wound around the suspension beam 1 when not in use, and it can be set at any corresponding position of the axis of the two adjacent rollers 62 when in use, and the height of the roller 61 to be aligned can be adjusted. In order to avoid position interference with the sliding groove 13, the transverse plumb 3 is set on the side of the vertical plumb 4 away from the end plumb 2, so that the transverse plumb 3, the vertical plumb 4 and the end plumb 2 are arranged at different axial positions of the roller 61 to be aligned to avoid position interference.

[0023] The wire bodies of the horizontal wire sinker 3, the vertical wire sinker 4 and the end wire sinker 2 can be made of nylon with good wear resistance, or other materials. Based on the principle of lightness and applicability, wire bodies with appropriate weight and diameter are selected. On the premise that the quality of the wire sinker meets the requirements of hoisting and alignment, a light weight sinker 42 can be appropriately selected to reduce the difficulty of operation and reduce procurement costs.

[0024] See also Figures 1 to 3In order to facilitate the collection of the horizontal line sinker 3 when it is not in use and avoid the horizontal line sinker 3 from being lost, a clamping groove 15 is provided on the bottom wall of the suspension beam 1. The line of the horizontal line sinker 3 can be conveniently clamped into the clamping groove 15, and then the horizontal line sinker 3 is wound around the suspension beam 1 to achieve the collection function. The inner diameter of the clamping groove 15 is slightly smaller than the outer diameter of the line of the horizontal line sinker 3, so that the line of the horizontal line sinker 3 can be clamped into the clamping groove 15.

[0025] In order to prevent the slot 15 from causing wear to the surrounding wall of the line of the horizontal line sinker 3, a flexible open sleeve is embedded in the slot 15. The flexible open sleeve is made of flexible materials such as rubber silicone, and the opening is set downward to facilitate the embedding of the line of the horizontal line sinker 3. The opening of the flexible open sleeve is through-through along its axial direction to accommodate the line of the horizontal line sinker 3.

[0026] See also Figures 1 to 3 The bottom of the suspension beam 1 is provided with a hanging ring 12 for connecting with the connecting line 41, and the connecting line 41 is an elastic line. The vertical plumb bob 4 is connected to the bottom of the suspension beam 1 through the connecting line 41, and the bottom wall of the suspension beam 1 is provided with a hanging ring 12 connected with the connecting line 41. The upper end of the connecting line 41 is fixed on the hanging ring 12. The connecting line 41 adopts a line body with elastic expansion and contraction performance. According to the distance between the suspension beam 1 and the roller 61 to be aligned above, the elastic line can adjust itself to the stretching and retracting state. On the basis of the connection between the vertical plumb bob 4 and the suspension beam 1, it will not interfere with the alignment of the roller 61 to be aligned. Even if the length of the elastic line is too large or too small, it will not affect the vertical alignment effect.

[0027] See also Figures 1 to 3 The middle part of the suspension beam 1 is provided with a winding drum 16 for winding the end line sinker 2, the horizontal line sinker 3 and the vertical line sinker 4. After the alignment roller 61 is aligned, the end line sinker 2, the horizontal line sinker 3 and the vertical line sinker 4 need to be retracted, and the winding drum 16 can be used for winding the end line sinker 2, the horizontal line sinker 3 and the vertical line sinker 4 to avoid affecting the normal production of the equipment.

[0028] See also Figures 1 to 3 , scale lines are provided on the peripheral wall of the transverse plumb line 3, and the zero scale of the scale lines is located at the midpoint of the transverse plumb line 3. When the transverse plumb line 3 is used to align the height position of the roller 61 to be aligned, in order to make the roller 61 to be aligned be located at the center position between the two adjacent rollers 62, scale lines are provided on the transverse plumb line 3. During alignment, the zero scale line should correspond to the axis of the roller 61 to be aligned, and the scales corresponding to the axes of the two rollers 61 to be aligned should be the same. At this time, the roller 61 to be aligned can be located at the center position between the two adjacent rollers 62, so that the distance between the roller 61 to be aligned and the adjacent rollers 62 on both sides is consistent, thereby improving the accuracy of the installation position.
