Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe production, and in particular to a steel pipe stacking and storage rack. Background Technology

[0002] After the steel pipes are produced, multiple steel pipes need to be neatly stacked together and then bundled together with steel straps. For example... Figure 1 As shown, this is a steel pipe stacking and storage rack, including a base plate 1. Multiple base plates 1 are evenly distributed at intervals. A left mounting plate 2 and a right mounting plate 3 are provided on the base plate 1. Both the left mounting plate 2 and the right mounting plate 3 are fixed to the base plate 1 by bolts. Multiple threaded holes 13 are provided on the base plate 1, and the relative positions of the left mounting plate 2 and the right mounting plate 3 can be adjusted. A left mounting block 21 is fixed on the left mounting plate 2. A left limiting roller 23 is rotatably connected to the side of the left mounting block 21 near the right mounting plate 3. A right mounting block 31 is fixed on the right mounting plate 3. A right limiting roller 33 is rotatably connected to the side of the right mounting block 31 near the left mounting block 21. The axes of the left limiting roller 23 and the right limiting roller 33 are both perpendicular to the base plate 1. A support conveyor roller 7 is set between two adjacent base plates 1. When stacking steel pipes, each steel pipe is placed between the left limit roller 23 and the right limit roller 33 and then placed on the support conveyor roller 7. After stacking, the support conveyor roller 7 transports the stacked steel pipes to the bundling station and bundles them with steel straps.

[0003] When the width of the stacking needs to be adjusted, the staff needs to adjust the distance between the left mounting plate 2 and the right mounting plate 3, unscrew the bolts on the left mounting plate 2 and the right mounting plate 3, move the left mounting plate 2 and the right mounting plate 3 to the appropriate position, and then fix them with bolts. This adjustment method is inefficient. In addition, the axes of the left limit roller 23 and the right limit roller 33 are both set perpendicular to the base plate 1, which can only stack square tubes. If it is necessary to stack round steel pipes, the left limit roller 23 and the right limit roller 33 need to be replaced. The left limit roller 23 and the right limit roller 33 need to be at a 60-degree angle to the base plate 1. Utility Model Content

[0017] The following is in conjunction with the appendix Figure 2 - Appendix Figure 3 The present invention will be described in further detail below.

[0018] Reference Figure 2 and Figure 3 This utility model discloses a steel pipe stacking and storage rack, including multiple base plates 1 spaced apart. The base plates 1 are fixed to the ground. A left mounting plate 2 and a right mounting plate 3 are provided on the base plates 1. Fixing plates 11 are provided on both sides of the left mounting plate 2 and both sides of the right mounting plate 3. A sliding groove 12 is formed between the two fixing plates 11. The left mounting plate 2 and the right mounting plate 3 are both located in the sliding groove 12 and can slide along the sliding groove 12.

[0019] A left mounting block 21 is provided above the left mounting plate 2. Two left support plates 22 are fixed on the side wall of the left mounting block 21. The two left mounting plates 2 are arranged vertically and vertically. A left limiting roller 23 is rotatably connected between the two left mounting plates 2. A first connecting component 4 is provided on the left mounting plate 2. The left mounting block 21 is connected to the left mounting plate 2 through the first connecting component 4.

[0020] A right mounting block 31 is provided on the right mounting plate 3. Two right support plates 32 are fixed on the side wall of the right mounting block 31. The two right mounting plates 3 are arranged vertically and vertically, and a right limiting roller 33 is rotatably connected between the two right mounting plates 3. A second connecting assembly 5 is provided on the right mounting plate 3, and the right mounting block 31 is connected to the right mounting plate 3 through the second connecting assembly 5. The left limiting roller 23 and the right limiting roller 33 are arranged opposite to each other. The second connecting assembly 5 has the same structure as the first connecting assembly 4.

[0021] The following description uses the first connecting component 4 as an example. The first connecting component 4 includes a first connecting block 41, a second connecting block 42, a third connecting block 43, and a fourth connecting block 44. The first connecting block 41 and the second connecting block 42 are both fixed on the left mounting plate 2. The bottom of the left mounting block 21 is hinged to the first connecting block 41. The third connecting block 43 and the fourth connecting block 44 are both fixed on the side wall of the left mounting block 21 away from the right limiting roller 33. The third connecting block 43 is located below the fourth connecting block 44. A support adjustment rod 45 is hinged to the top of the second connecting block 42.

[0022] The support adjustment rod 45 includes a first rod body 451, a second rod body 452, and a third rod body 453. The second rod body 452 is located between the first rod body 451 and the third rod body 453. Both the first rod body 451 and the third rod body 453 have telescopic holes on their adjacent sides. The second rod body 452 is a threaded rod, and the helical directions of the threads on the second rod body 452 are opposite from the middle to both ends. One end of the second rod body 452 is inserted into the telescopic hole of the first rod body 451 and threadedly connected to it. The other end of the second rod body 452 is inserted into the telescopic hole of the third rod body 453 and threadedly connected to it.

[0023] An adjusting block 454 is fixed at the middle position of the second rod 452. By rotating the adjusting block 454, the length of the second rod 452 inserted into the first rod 451 and the third rod 453 can be adjusted, thereby adjusting the overall length of the supporting adjusting rod 45.

[0024] The end of the first rod 451 furthest from the second rod 452 is hinged to the top of the second connecting block 42. The end of the third rod 453 furthest from the second rod 452 is hinged to the third connecting block 43 or the fourth connecting block 44. A pin 455 is provided on the third rod 453, which is hinged to either the third connecting block 43 or the fourth connecting block 44 via the pin 455. When the third rod 453 is hinged to the third connecting block 43, the left limiting roller 23 is at a 90-degree angle to the base plate 1. If there is a slight deviation, the second rod 452 can be adjusted. When the left limiting roller 23 and the right limiting roller 33 are at a 90-degree angle to the base plate 1, square tubes can be stacked. When the third rod 453 is hinged to the fourth connecting block 44, the left and right limiting rods are at a 60-degree angle to the base plate 1, allowing round tubes to be stacked.

[0025] A drive assembly 6 is provided on the base plate 1 to drive the left mounting plate 2 and the right mounting plate 3 to move closer or further apart. The drive assembly 6 includes a drive rod 61 and a motor reducer 62. The drive rod 61 includes a left drive rod 611 and a right drive rod 612, with opposite thread directions. A flange plate 613 is fixed to the end of the left drive rod 611 and the right drive rod 612 that are close to each other, and the two flange plates 613 are fixed by bolts.

[0026] The left drive rod 611 passes through the first connecting block 41 and the second connecting block 42 on the left mounting plate 2, and is threadedly connected to both the first connecting block 41 and the second connecting block 42. The right drive rod 612 passes through the first connecting block 41 and the second connecting block 42 on the right mounting plate 3, and is threadedly connected to both the first connecting block 41 and the second connecting block 42. The motor reducer 62 is fixed on the base plate 1, and the output shaft of the motor reducer 62 is fixed to the right drive rod 612. When the overall width of the stack increases, the motor reducer 62 can drive the drive rod 61 to rotate, thereby causing the left mounting plate 2 and the right mounting plate 3 to move away from each other, thereby increasing the distance between the left limiting roller 23 and the right limiting roller 33, thus enabling the stacking of steel pipes with larger widths to be accommodated.

[0027] Multiple base plates 1 are provided along the length of the steel pipe. Each base plate 1 is equipped with a left limiting roller 23 and a right limiting roller 33. The left limiting rollers 23 on all base plates 1 should be in a straight line, and the right limiting rollers 33 should also be in a straight line. After adjusting the left limiting rollers 23 and right limiting rollers 33, it is possible that the right limiting rollers 33 on all base plates 1 are aligned, while the left limiting roller 23 on one base plate 1 is not aligned with the left limiting rollers 23 on the other base plates 1. In this case, it is necessary to separate the left drive rod 611 and right drive rod 612 on the misaligned base plate 1 and adjust the left drive rod 611 individually to align the left limiting roller 23 with the other left limiting rollers 23.

[0028] A support conveyor roller 7 is installed between the base plates 1 and 1, and the steel pipes are placed on the support conveyor roller 7. After the steel pipes are stacked, they need to be transported to the bundling station for bundling via the support conveyor roller.

[0029] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
