[0002] With the rapid development and construction of oil and gas projects both onshore and offshore, the requirements for corrosion protection of pipeline steel pipes are becoming increasingly stringent. In the process of wrapping steel pipes with PE (polyethylene) for corrosion protection, precise control of applied force is necessary to ensure the quality of the PE wrapping. However, existing equipment has shortcomings in force detection and control, making it difficult to meet the requirements for high-quality PE wrapping. Utility Model Content

A cylinder for driving the support frame to rotate up and down is installed between the front part of the base and the front part of the support frame. The air inlet of the cylinder is connected to a pneumatic pressure sensor. Two symmetrical bearing seat load cells are installed at the top of the support frame. A set of first seated bearings is installed at the top of each bearing seat load cell. The two ends of the pressure roller are respectively installed in the inner rings of the two sets of first seated bearings.

[0006] The base includes a rectangular base frame and two parallel columns. The columns are vertically fixed to the rear top of the base frame. A set of second bearings with seats is installed at the top of each column. The bottom of the cylinder is hinged to the front of the base frame.

[0007] The support frame includes a first U-shaped arm and a second U-shaped arm. The opening direction of the first U-shaped arm is opposite to that of the second U-shaped arm. The middle part of the first U-shaped arm is fixedly connected to the middle part of the second U-shaped arm. A hinge shaft is fixedly connected to the outer side of each end of the first U-shaped arm. The two hinge shafts are respectively sleeved in the inner rings of two sets of second seated bearings.

[0011] The beneficial effects of this invention are as follows: When the steel pipe is wound with anti-corrosion PE, the cylinder action lifts the support frame, causing the pressure roller installed between the two first bearing seats to apply pressure to the steel pipe.

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 3 As shown, a pressure detection and control device for a steel pipe anti-corrosion PE winding pressure roller includes an L-shaped base 1, a support frame 2, and a pressure roller 3.

[0019] The base 1 includes a rectangular base frame 11 and two parallel columns 12, which are vertically fixed to the top rear part of the base frame 11.

[0020] The support frame 2 includes a first U-shaped arm 21 and a second U-shaped arm 22. The opening direction of the first U-shaped arm 21 is opposite to the opening direction of the second U-shaped arm 22. The middle part of the first U-shaped arm 21 is fixedly connected to the middle part of the second U-shaped arm 22.

[0021] The rear of the support frame 2 is hinged to the top of the base 1. Specifically, a set of second bearings 13 with seats are installed at the top of each column 12. A hinge shaft 23 is fixed to the outer side of each end of the first U-shaped arm 21. The two hinge shafts 23 are respectively fitted into the inner rings of the bearings of the two sets of second bearings 13 with seats.

[0022] A cylinder 4 is installed between the front part of the base 1 and the front part of the support frame 2 to drive the support frame 2 to rotate up and down. Specifically, the bottom of the cylinder 4 is hinged to the front part of the base frame 11, and the two ends of the first U-shaped arm 21 are respectively hinged to the top of the piston rod of the cylinder 4.

[0023] The air inlet of cylinder 4 is connected to a pressure sensor 5, which has a dial 51 for displaying the pressure value.

[0024] Two symmetrical bearing seat load cells 6 are installed at the top of the support frame 2. A set of first seated bearings 7 are installed at the top of each bearing seat load cell 6. The two ends of the pressure roller 3 are respectively installed in the inner ring of the two sets of first seated bearings 7. The pressure roller 3 presses against the bottom of the steel pipe 100. The outer side of the pressure roller 3 is covered with a silicone layer to avoid scratching the anti-corrosion PE material layer wrapped on the surface of the steel pipe.

[0025] To facilitate intuitive reading of the vertical pressure monitored by the bearing housing load cell 6, this device also includes a digital display. The signal input terminal of the digital display is connected to the signal output terminals of the two bearing housing load cells 6 via data cables.

[0026] During the process of winding anti-corrosion PE onto the steel pipe, the cylinder actuates to lift the support frame, causing the pressure roller installed between the two first bearing seats to apply pressure to the steel pipe. The bearing seat load cell measures the pressure of the pressure roller on the steel pipe in real time, while the air pressure sensor simultaneously detects the air pressure inside the cylinder. This data collection of pressure and air pressure values ​​provides a good big data guarantee for the accumulation of subsequent process technologies. The operator adjusts the air pressure of the cylinder according to the pressure and air pressure values ​​to achieve precise control of the force applied by the pressure roller to the steel pipe, thereby achieving the ideal anti-corrosion PE winding effect.

[0027] To facilitate automated control, the bearing housing load cell 6 and the air pressure sensor 5 are connected to the control system of the steel pipe anti-corrosion PE winding device via data cables, transmitting the pressure and air pressure values ​​to the control system of the steel pipe anti-corrosion PE winding device in real time.
