Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the embodiment, Figure 1-4 A back plate pressing device for petrochemical equipment is provided, comprising a workbench 1, wherein two vertical plates 2 are fixedly connected to the top of the workbench 1, two driving shafts 3 are rotatably connected between the two vertical plates 2, active pressing rollers 4 are fixedly connected to the outer sides of the two active shafts 3, two up-and-down moving components 5 are arranged on the two vertical plates 2, a driven shaft 6 is rotatably connected between the two adjacent up-and-down moving components 5, a driven pressing roller 7 is fixedly connected to the outer sides of the driven shaft 6, and the two driven pressing rollers 7 are located above the two active pressing rollers 4, two guide components 8 for back plate guiding are arranged between the two vertical plates 2, a driving component 9 for driving the two driving shafts 3 to rotate is arranged on the workbench 1, and a receiving plate 10 is fixedly connected to the left and right ends of the two vertical plates 2;

[0023] The guide assembly 8 includes a guide rod 81, two guide rods 81 are fixedly connected between the two vertical plates 2, the outer sides of the two guide rods 81 are slidably connected to two sliding seats 82, a screw rod 83 is rotatably connected between the two vertical plates 2, a hand wheel 84 is fixedly connected to the screw rod 83, one sliding seat 82 is threadedly connected to the outer side of the screw rod 83, and the other sliding seat 82 is rotatably connected to the outer side of the screw rod 83, and two guide wheels 85 are rotatably connected to the two sliding seats 82.

[0024] Through the above arrangement, the petrochemical equipment back plate is first placed on the receiving plate 10, and the petrochemical equipment back plate is gradually pushed between the two active pressure rollers 4 and the two driven pressure rollers 7. The two active pressure rollers 4 and the two driven pressure rollers 7 are clamped between the two active pressure rollers 4 and the two driven pressure rollers 7 by adjusting the up and down moving components 5. The driving component 9 is started, and the two active shafts 3 are driven to rotate by the driving component 9. The two active shafts 3 drive the two active pressure rollers 4 to rotate. The petrochemical equipment back plate is pressed into shape by the two active pressure rollers 4 and the two driven pressure rollers 7. During the rotation of the two active pressure rollers 4, the two driven pressure rollers 7 will also rotate. The petrochemical equipment back plate will be clamped between the guide wheels 85 on the front and rear sides. In order to avoid the deflection of the back plate of the petrochemical equipment, when it is necessary to press the back plate of different petrochemical equipment, turn the hand wheel 84 and the screw rod 83 to rotate. At this time, the sliding seat 82 threadedly connected to the screw rod 83 will move along the center line direction of the screw rod 83, thereby changing the position of the sliding seat 82, and then the relative distance between the front and rear guide wheels 85 can be changed to adapt to back plates of different sizes. It should be noted that the front sliding seat 82 in the left guide assembly 8 of this device is threadedly connected to the outer side of the screw rod 83, and the rear sliding seat 82 is rotatably connected to the outer side of the screw rod 83, while the front sliding seat 82 in the right guide assembly 8 is rotatably connected to the outer side of the screw rod 83, and the rear sliding seat 82 is threadedly connected to the outer side of the screw rod 83.

[0026] Through the above-mentioned structural setting, the threaded rod 54 is rotated, and the threaded rod 54 moves upward or downward along the inner side of the fixed seat 53, thereby changing the position of the up-and-down movable seat 52, and finally changing the position of the driven shaft 6 and the driven pressure roller 7, ensuring that the two active pressure rollers 4 and the two driven pressure rollers 7 clamp the back plate of the petrochemical equipment between the two active pressure rollers 4 and the two driven pressure rollers 7. It should be noted that the threaded rod 54 is rotatably connected to the inner side of the up-and-down movable seat 52 and is limited to the inner side of the up-and-down movable seat 52, so that the threaded rod 54 cannot be separated from the up-and-down movable seat 52.

[0028] Through the above-mentioned structural setting, the driving motor 91 is started, and the power is transmitted to the right driving shaft 3 under the transmission action of the first sprocket chain transmission mechanism 92, so that the right driving shaft 3 rotates. Since the two driving shafts 3 are connected through the second sprocket chain transmission mechanism 93, the two driving shafts 3 rotate, and finally drive the two active pressure rollers 4 to rotate.
