[0002] Currently, coal chemical and petrochemical projects often involve the rounding of key components of chemical containers such as large-diameter heads and cylinders. In actual operation, due to stress concentration, the edges of large-diameter heads and cylinders after welding are usually deformed locally, resulting in out-of-tolerance ellipticity. This leads to problems such as low production efficiency, long production cycle, and a large number of defective products, resulting in material waste. Summary of the Invention

The hydraulic cylinder is installed inside the portable frame, the pressure head is connected to the piston rod of the hydraulic cylinder and is driven by the hydraulic cylinder to perform telescopic movement, and the support foot is disposed on the inner wall of the portable frame opposite to the pressure head.

[0005] Furthermore, the portable intelligent device for rounding chemical container components also includes: a protective frame, a motor, and a hydraulic system. The protective frame is connected to the outer wall of the portable frame, the motor is mounted on the protective frame, the motor is powered by an external cable, the motor is connected to the hydraulic system through a reducer, and the hydraulic system is located inside the protective frame and communicates with the hydraulic cylinder.

[0006] Furthermore, in the aforementioned portable intelligent device for rounding chemical container components, the hydraulic system includes a hydraulic oil tank, an oil pump, and a circulation pipeline. The motor is connected to the oil pump via a reducer, the input end of the oil pump is connected to the output end of the hydraulic oil tank, and the hydraulic cylinder is connected to the oil pump and the hydraulic oil tank via the circulation pipeline.

[0007] Furthermore, in the aforementioned portable intelligent device for rounding chemical container components, the hydraulic cylinder is a double-acting cylinder, including a left chamber and a right chamber. The circulation pipeline includes: a main oil supply pipeline, two branch oil supply pipelines, and two return oil pipelines. The input end of the main oil supply pipeline is connected to the oil pump, and a reversing valve is installed at the output end of the main oil supply pipeline.

[0008] Furthermore, in the aforementioned portable intelligent device for rounding chemical container components, the hydraulic oil in the hydraulic cylinder is filtered clean oil.

[0009] Furthermore, the portable intelligent device for rounding chemical container components also includes a measurement and control component, which is mounted on the protective frame.

[0010] Furthermore, in the aforementioned portable intelligent device for rounding chemical container components, the pressure head and the support foot have matching curved shapes that fit the chemical container component to be rounded.

[0011] Furthermore, in the aforementioned portable intelligent device for rounding chemical container components, the pressure head is detachably connected to the piston rod of the hydraulic cylinder, and the support foot is detachably mounted on the portable frame.

[0012] In another aspect of the present invention, the provided method for rounding chemical container components includes the following steps:

[0014] Step S2: Switch the reversing valve so that the oil supply branch line connected to the left chamber of the hydraulic cylinder is connected to the main oil supply line, and the oil return line connected to the right chamber of the hydraulic cylinder is connected to the hydraulic oil tank. The oil pump driven by the motor injects hydraulic oil into the left chamber of the hydraulic cylinder, so that the pressure head is away from the support foot.

If the actual curvature meets the target curvature, then step S5 is executed; if the actual curvature does not meet the target curvature, then step S4 is executed again to round the chemical container component again.

The hydraulic cylinder 2 is installed inside the portable frame 1, the pressure head 3 is connected to the piston rod of the hydraulic cylinder 2 and is driven by the hydraulic cylinder 2 to perform telescopic movement, and the support foot 4 is disposed on the inner wall of the portable frame 1 opposite to the pressure head 3.

[0031] Preferably, the pressure head 3 is detachably connected to the piston rod of the hydraulic cylinder 2, and the support foot 4 is detachably mounted on the portable frame 1.

[0032] Preferably, the portable intelligent device for rounding chemical container components further includes: a protective frame 5, a motor 6, and a hydraulic system 7. The protective frame 5 is connected to the outer wall of the portable frame 1. The motor 6 is mounted on the protective frame 5 and powered by an external cable. The motor 6 is connected to the hydraulic system 7 through a reducer. The hydraulic system 7 is located inside the protective frame 5 and communicates with the hydraulic cylinder 2.

[0033] The motor 6 is powered by an external cable, making it easy to carry to the chemical plant site. Its portability allows for on-site, online rounding of chemical container components such as heads and cylinders, eliminating the need for component disassembly and transportation, thus reducing economic and time costs.

[0034] The protective frame 5 effectively protects the internal hydraulic system 7 from impacts, collisions, and potentially corrosive environments on site, improving the overall durability of the equipment.

[0035] Preferably, the hydraulic system 7 includes a hydraulic oil tank 8, an oil pump 9, and a circulation pipeline. The motor 6 is connected to the oil pump 9 through a reducer. The input end of the oil pump 9 is connected to the output end of the hydraulic oil tank 8. The hydraulic cylinder 2 is connected to the oil pump 9 and the hydraulic oil tank 8 through the circulation pipeline.

[0036] Preferably, the hydraulic cylinder 2 is a double-acting cylinder, including a left chamber 15 and a right chamber 16. The circulation pipeline includes: a main oil supply pipeline 10, two branch oil supply pipelines 11, and two return oil pipelines 12.

The directional valve 13 is used to switch the flow direction of the hydraulic oil. The input ends of the two branch oil supply pipelines 11 are respectively connected to the two output ends of the directional valve 13. The output ends of the two branch oil supply pipelines 11 are respectively connected to the left chamber 15 and the right chamber 16. The input ends of the two return oil pipelines 12 are respectively connected to the left chamber 15 and the right chamber 16.

[0037] Preferably, the portable intelligent device for rounding the chemical container component further includes a measurement and control component 17, which is mounted on the protective frame 5. The measurement and control component 17 is used to measure the actual curvature of the component and control the piston rod stroke of the hydraulic cylinder 2 according to the actual curvature and the target curvature required by the component.

[0038] Preferably, the hydraulic oil in the hydraulic cylinder 2 is filtered clean oil. Using filtered clean hydraulic oil effectively prevents oil circuit blockage, valve jamming, and internal wear of the hydraulic cylinder 2. Especially in chemical environments where impurities may exist, it ensures the long-term stable and reliable operation of the hydraulic system 7, reducing the failure rate and maintenance requirements.

[0039] Preferably, the pressure head 3 and the support foot 4 have matching curved shapes to fit the round chemical container component to be repaired.

[0040] Preferably, the pressure head 3 and the support foot 4 are configured with multiple specifications. By setting multiple specifications of pressure head 3 and support foot 4, the corresponding specifications of pressure head 3 and support foot 4 can be matched according to the size, shape, material and other characteristics of the part to be rounded, thereby adapting to the rounding of parts of multiple specifications.

[0041] The measurement and control component 17 monitors the actual curvature of the component and the piston rod stroke of the hydraulic cylinder 2 in real time, realizing quantitative monitoring and intelligent control of the rounding process of chemical container components. This ensures the precise matching between the correction force applied to the component and the amount of deformation, effectively avoiding undercorrection or overcorrection, greatly improving the rounding accuracy and success rate, and reducing rework.

[0042] The method for rounding chemical container components provided by this invention includes the following steps:

[0043] Step S1: Determine the target curvature required for the component according to the actual application requirements, and input the target curvature into the measurement and control component 17;

[0044] Step S2: Switch the reversing valve 13 so that the oil supply branch line 11 connected to the left chamber 15 of the hydraulic cylinder 2 is connected to the main oil supply line 10, and the return oil line 12 connected to the right chamber 16 of the hydraulic cylinder 2 is connected to the hydraulic oil tank 8. Drive the oil pump 9 through the motor 6 to inject hydraulic oil into the left chamber 15 of the hydraulic cylinder 2, so that the pressure head 3 is away from the support foot 4.

[0045] Step S3: Place the round part to be repaired between the pressure head 3 and the support foot 4, switch the reversing valve 13 so that the oil supply branch line 11 connected to the right chamber 16 of the hydraulic cylinder 2 is connected to the main oil supply line 10, and the return oil line 12 connected to the left chamber 15 of the hydraulic cylinder 2 is connected to the hydraulic oil tank 8. Drive the oil pump 9 through the motor 6 to inject hydraulic oil into the right chamber 16 of the hydraulic cylinder 2, so that the pressure head 3 is close to the support foot 4, thereby positioning the round part to be repaired.

[0046] Step S4: The measurement and control component 17 detects the real-time position of multiple measuring points on the round part to be repaired. Based on the real-time position of the measuring points, the internal calculation program integrated in the measurement and control component 17 calculates the actual curvature of the round part to be repaired. Then, the piston rod stroke of the hydraulic cylinder 2 is controlled according to the actual curvature and the target curvature, thereby rounding the part.

[0047] Step S5: Switch the reversing valve 13 so that the oil supply branch line 11 connected to the left chamber 15 of the hydraulic cylinder 2 is connected to the main oil supply line 10, and the return oil line 12 connected to the right chamber 16 of the hydraulic cylinder 2 is connected to the hydraulic oil tank 8. Drive the oil pump 9 through the motor 6 to inject hydraulic oil into the left chamber 15 of the hydraulic cylinder 2, so that the pressure head 3 is away from the support foot 4, and the rounded part is taken out.

[0048] Preferably, after step S4 and before step S5, step S40 is also included: after the component is rounded, the measurement and control component 17 detects the real-time position of multiple measurement points on the component, and the internal calculation program integrated in the measurement and control component 17 calculates the actual curvature of the component based on the real-time position of the measurement points, and determines whether the actual curvature meets the target curvature. If the actual curvature meets the target curvature, step S5 is executed; if the actual curvature does not meet the target curvature, step S4 is executed again to round the component again.

[0049] The portable intelligent device and method for rounding chemical container components of this invention, through precise control of the curvature of the chemical container component to be rounded, combined with a conveniently designed operating space, overcomes the technical difficulties of rounding key components in previous coal chemical and petrochemical projects. It realizes the pressing and repair of any position of the chemical container component to be rounded, and thus achieves accurate control of the material rebound during the rounding of the chemical container component. This ensures that the diameter and roundness of chemical container components such as large-diameter heads and cylinders can accurately meet the design requirements, reduces material loss caused by the occurrence of defective products, and has the advantages of high precision and easy operation. It also significantly shortens the production cycle and improves production efficiency.
