Description

Technical Field

[0001] This utility model belongs to the field of hydrogen pipeline processing, specifically, it relates to a high-precision cutting device for hydrogen pipelines. Background Technology

[0002] Hydrogen pipelines are used to transport gaseous energy. When laying the pipelines, they need to be cut according to the requirements of the ground routing to meet the laying requirements.

[0003] Currently, during cutting, the hydrogen pipeline to be cut needs to be fixed. However, existing fixing equipment cannot detect whether the fixation is secure and can only rely on the operator's feel. Therefore, it is easy to affect the cutting accuracy. If the fixation is too loose, the pipeline position may loosen during the cutting process, thus affecting the cutting accuracy. If the fixation is too tight, it may cause excessive pressure on the pipeline body, resulting in pipeline deformation. In view of this, this utility model is proposed. Utility Model Content

A first polyurethane ring is sleeved on the outside of the first guide rod, and the first polyurethane ring is fixed to the top of one of the fixed seats. The backs of the two fixed seats are fixed by the same connecting strip.

[0013] Optionally, the upper end of the workbench is also provided with an electromagnetic track. A housing is fixed to the top of the movable end of the electromagnetic track.

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Please see Figures 1 to 8 This utility model provides a technical solution: a high-precision cutting device for hydrogen pipelines, including a base 1, a workbench 2, a fixed support 8 and a detection pad 14. The workbench 2 is fixed on the top of the base 1. The four corners of the upper end of the workbench 2 are fixed to the bottom of the same top cover 3 by support columns. The opposite surfaces of the workbench 2 and the top cover 3 are provided with fixed seats 4. The opposite surfaces of the two fixed seats 4 are fixed with irregular blocks 6 for T-shaped blocks 5 to be inserted. Spring pins 7 are installed on both sides of each irregular block 6. The pin head of each spring pin 7 passes through the irregular block 6 and is inserted into the grooves on both sides of the T-shaped block 5.

[0033] Two T-shaped blocks 5 are fixed with fixing brackets 8 for fixing hydrogen pipelines on their opposite sides. The contact surface between the fixing brackets 8 and the pipeline is provided with abutment grooves 9 that are adapted to the curvature of the outer surface of the hydrogen pipeline being processed. The bottom of each abutment groove 9 is fixed with a hook surface 11 for attaching the hook and loop surface 10. The hook and loop surface 10 is fixed to the lower surface of the detection pad 14. Anti-slip pads 12 are also provided at the front and back of the abutment groove 9. Anti-slip strips 13 are provided at equal intervals on the upper surface of the detection pad 14. A thin film pressure sensor 15 is provided inside the detection pad 14. The thin film pressure sensor 15 is connected to the inside of the fixing base 4 and the processor 16 through a wire. The upper end of the processor 16 is connected to the touch screen 17 at the front end of the fixing base 4 through a wire.

[0034] One side of each of the two fixed supports 8 is equipped with a blade 18 for cutting hydrogen pipelines. Currently, during cutting, the hydrogen pipeline needs to be secured, but existing securing equipment cannot detect whether the fixation is secure, relying solely on the operator's feel. This can easily affect cutting accuracy; if the fixation is too loose, the pipeline may shift during cutting, affecting precision. If the fixation is too tight, excessive pressure can cause pipeline deformation. This invention addresses this issue by incorporating a thin-film pressure sensor 15, a processor 16, and a touchscreen 17 within the detection pads 14 on the opposite sides of the two fixed supports 8, facilitating the cutting process. The operator can determine whether the hydrogen pipeline being processed is securely fixed. After the upper fixing bracket 8 is pressed down by the first electric push rod 31, the thin-film pressure sensor 15 obtains analog data. The data is processed by the processing chip, AD converter, and DA converter built into the processor 16. The processing result is then organized into data that can be displayed on the touch screen 17. The operator can then visually observe whether the hydrogen pipeline being processed is within the threshold range for secure fixing, thereby determining whether it is securely fixed. Furthermore, the operator can compare the standard pressure value to determine whether the fixing is too tight or too loose, avoiding material displacement due to insecure fixing, which would affect processing accuracy.

[0035] The workbench 2 has cavities for mounting the first motor 19 and the reciprocating screw 20. One end of the reciprocating screw 20 is fixed to the output shaft of the first motor 19 via a coupling, and the other end of the reciprocating screw is connected to the side of the cavity via a bearing. A threaded sleeve 21 is installed on the outside of the reciprocating screw 20. The lower end of the threaded sleeve 21 is fixed to the slider 22. The slider 22 is slidably connected to the upper end of the slide rail 23 at the bottom of the cavity. The upper end of the threaded sleeve 21 is fixed to the bottom of the fixed seat 4. The first motor 19, in conjunction with the reciprocating screw 20, drives the threaded sleeve 21. When the threaded sleeve 21 is driven, the fixed seat 4 at the lower end will move horizontally. This process is guided by the slider 22 and the slide rail 23. The movement of the lower fixed seat 4 will synchronously drive the upper fixed seat 4 to move via the connecting strip 34.

[0036] The upper end of the workbench 2 is provided with a clearance groove for the fixed seat 4 to move horizontally. Dustproof bellows plates 24 are fixed on both sides inside the clearance groove, and the other side of the two dustproof bellows plates 24 are fixed to the two sides of the fixed seat 4 respectively. By setting the dustproof bellows plates 24, it is prevented that debris enters the cavity and adheres to the surface of the reciprocating screw 20 during the pipe cutting process, thus affecting the transmission.

[0037] The cavity for mounting the first motor 19 is fitted with a dustproof net 25 by screws on one side. Multiple cooling fans 26 are fixed to the outside of the dustproof net 25 by brackets. A controller 27 is provided on the front side of the workbench 2. By setting the dustproof net 25, the first motor 19 is cooled while preventing dust from entering.

[0038] The top cover 3 has a guide rail 29 fixed at its bottom for the horizontal movement of the guide block 28. The bottom of the guide block 28 is fixed to the drive box 30 with screws. The drive box 30 has a first electric push rod 31 fixed inside. The telescopic end of the first electric push rod 31 passes through the drive box 30 and is fixed to the top of one of the fixed seats 4. The bottom of the drive box 30 has clearance holes on both sides for the first guide rod 32 to pass through. The first guide rod 32 is fixed to the top of one of the fixed seats 4. The first polyurethane ring 33 is sleeved on the outside of the first guide rod 32 and is fixed to the top of one of the fixed seats 4. The backs of the two fixed seats 4 are fixed by the same connecting strip 34. The first guide rod prevents the fixed seats 4 driven by the first electric push rod 31 from shifting position. The presence of the first polyurethane ring 33 prevents the fixed seats 4 and the drive seat from being damaged by collision when the telescopic end of the first electric push rod 31 retracts.

[0039] The upper end of the workbench 2 is equipped with an electromagnetic track 35. The top of the movable end of the electromagnetic track 35 is fixed with a housing 36. Inside the housing 36, a second electric push rod 37 is fixed. The telescopic end of the second electric push rod 37 passes through the housing 36 and is fixed to the bottom of the kit 38. The bottom of the kit 38 is symmetrically fixed with second guide rods 39. The ends of the second guide rods 39 all pass through the inside of the housing 36. The outside of the second guide rods 39 is fitted with a second polyurethane ring 40, and the second polyurethane ring 40 is fixedly connected to the top of the housing 36. The kit 38 has a reserved slot for placing the box. The top of the reserved slot is threaded with a limit bolt 41. The movement of the movable end driven by the electromagnetic slide rail 23 moves the housing 36. The presence of the second electric push rod 37 adjusts the cutting height of the blade 18.

[0040] The box contains a second motor 42, whose output shaft is fixed to a connecting shaft 43 via a coupling. A positioning ring 44 for contacting the blade 18 is fixedly fitted onto the middle of the connecting shaft 43. The end of the connecting shaft 43 has threads for screwing in a nut 45. A limiting ring 46 matching the size of the positioning ring 44 is fitted onto the outside of the end of the connecting shaft 43. A fixing hole matching the position of the positioning post 47 on the side of the positioning ring 44 is opened through the middle of the limiting ring 46. Anti-slip rings 48 are fixed on the front left and right sides of the limiting ring 46. The second motor 42 drives the blade 18. After the pipeline is fixed, the rotating blade 18 can be brought into contact with the outer wall of the hydrogen pipeline by the retraction end of the second electric push rod 37, thus completing the cutting process. The limiting ring 46, which cooperates with the nut 45, fixes the blade 18.

[0041] The upper end of the kit 38 is fixed with an L-shaped part 49. Two first laser positioning lights 50 are fixed at the horizontal end of the L-shaped part 49. The two first laser positioning lights 50 are symmetrically distributed about the central axis of the blade 18. The middle opposite surfaces of the two fixed supports 8 are symmetrically fixed with second laser positioning lights 51. By setting the first laser positioning lights 50, the user can easily know the cutting area of ​​the blade 18. The second laser positioning lights 51 make it easier for the user to know the clamping area of ​​the two fixed supports 8.
