Description

Technical Field

[0001] This invention relates to the field of pipeline laying technology, specifically to a device for rapid connection of pressure pipelines. Background Technology

[0002] In industrial sectors such as petroleum, chemical, and natural gas transportation, pressure pipelines serve as critical infrastructure for fluid transmission. Their connection efficiency and sealing performance play a decisive role in the safe and stable operation of the system. When connecting pressure pipelines, it is necessary to align the two pipelines together to facilitate subsequent welding.

[0003] For the connection of pressure pipelines, as proposed in authorization announcement number CN116179331B, a pipeline connection device for water conservancy projects includes a large base, an electric slide rail, a small base, traveling wheels, an electric slider, a preliminary calibration component, and a support and limiting mechanism.

[0004] For example, the authorization announcement number CN118513779B proposes a device for quick docking of pressure pipelines. The device includes a plate body, with fixed seats fixedly connected to both ends of the plate body. A half-clamp is fixedly installed on one side of each fixed seat. Rotary rods are rotatably connected to both ends of one side of the plate body, and a rotating cylinder is rotatably connected to one end of each rotating rod.

However, pressure pipelines are relatively heavy, and manual handling is very laborious. If hoisting equipment is used for hoisting, special pipeline hoisting equipment is required, which not only increases equipment investment but also increases the complexity of construction.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1-10 In this embodiment of the invention, a device for rapid connection of pressure pipelines includes a frame 1. Hollow columns 12 are fixedly connected to each of the four corners of the frame 1. Each hollow column 12 contains a liftable movable component 7. Each movable component 7 includes a hollow slide rod 72, which is slidably connected inside the hollow column 12. A third electric cylinder 71 is fixedly connected inside the hollow slide rod 72, and the output end of the third electric cylinder 71 is fixedly connected to the upper inner surface of the hollow column 12. A caster wheel 73 is installed at the lower end of each hollow slide rod 72. The third electric cylinder 71 can raise and lower the hollow slide rod 72, thereby adjusting the height of the frame 1 during operation. This allows for appropriate adjustments based on the pipeline connection height during use. The caster wheel 73 facilitates movement.

[0039] Both ends of the frame 1 are fixedly connected to semi-circular blocks 2. Each semi-circular block 2 is equipped with a docking assembly 8 for connecting pipes. The docking assembly 8 includes a rotating seat 82, which is fixedly connected to both sides of the frame 1 near the semi-circular blocks 2. Each side of the lower end of the semi-circular blocks 2 is provided with a sloping closing block 81. Each sloping closing block 81 is provided with several rollers 80. A support arm 89 is fixedly connected to the upper end of the sloping closing block 81 away from the center of the semi-circular block 2. The support arm 89 is rotatably connected to the rotating seat 82. Limiting sliding columns 88 are fixedly connected between the upper ends of the semi-circular blocks 2 and the top crossbar of the frame 1. A T-shaped frame 86 is slidably connected between the two limiting sliding columns 88. The vertical rod of the T-shaped frame 86 is slidably connected to the semi-circular blocks 2. A lifting mechanism is fixedly connected to the lower end of the T-shaped frame 86, which penetrates into the semi-circular blocks 2. The arc plate 83 and the crossbar of the T-shaped frame 86 are rotatably connected to both ends of the connecting rod 84. The end of the connecting rod 84 away from the T-shaped frame 86 is rotatably connected to the middle of the support arm 89. The limiting slide column 88 is located between the T-shaped frame 86 and the upper crossbar of the frame 1 and is equipped with a return spring 85. The limiting slide column 88 is located below the limiting ring 87 and is fixedly connected to the limiting ring 87. A locking component for locking is also provided between the lower ends of the two inclined sealing blocks 81. During operation, when the pipeline is lifted, the pipeline will push the lifting arc plate 83 to move upward. The upward movement of the lifting arc plate 83 will drive the T-shaped frame 86 to move upward. The upward movement of the T-shaped frame 86 can drive the connecting rod 84 to move accordingly. The movement of the connecting rod 84 can drive the support arm 89, thereby causing the two inclined sealing blocks 81 to flip and close. After closing, the locking component automatically closes the two inclined sealing blocks 81, thereby supporting the pipeline.

[0040] The locking assembly includes a perforated locking plate 811, which is fixedly connected to the lower ends of both sides of the semi-circular block 2. Each side of the inclined closed block 81 near the rotating seat 82 has a mounting cavity 812. An iron slider 815 is slidably connected inside the mounting cavity 812. Push springs 813 are installed between both ends of the iron slider 815 and the inner end face of the mounting cavity 812. An electromagnet 814 is installed in the middle of the inner end face of the mounting cavity 812. An inclined locking block 816 is fixedly connected to the side of the iron slider 815 away from the electromagnet 814, and the inclined locking block 816 is slidably connected to the inclined closed block 81. The inclined locking block 816 is adapted to the locking hole on the perforated locking plate 811. When the two inclined closing blocks 81 are closed, the perforated locking plate 811 will push the inclined locking block 816 into the mounting cavity 812 under the action of the inclined surface. When the locking hole of the perforated locking plate 811 is in place, the inclined locking block 816 will extend into the locking hole of the perforated locking plate 811 to lock. When it is necessary to release the perforated locking plate 811, the electromagnet 814 will be activated to attract the iron slider 815, so that the inclined locking block 816 will retract into the mounting cavity 812, thereby unlocking the perforated locking plate 811. After unlocking, the inclined closing block 81 will be reset under the action of the return spring 85.

[0041] Fixed arms 3 are fixedly connected to both sides of one end of the frame 1. A docking block 14 is fixedly connected between the ends of the two fixed arms 3 away from the frame 1. A V-groove 15 is provided at the lower end of the docking block 14. A fixing component 4 for fixing with the pipeline is provided inside the docking block 14. The fixing component 4 includes a first electric push rod 41, which is fixedly connected to the upper end of the docking block 14. An arc-shaped pressure plate 43 is fixedly connected to the output end of the first electric push rod 41. Limiting slide rods 42 are fixedly connected to both sides of the arc-shaped pressure plate 43. The limiting slide rods 42 are slidably connected to the upper end of the docking block 14. During operation, the output end of the first electric push rod 41 moves to push the arc-shaped pressure plate 43 to move. The arc-shaped pressure plate 43 moves and cooperates with the V-groove 15, thereby achieving the fixing with the installed pipeline.

[0042] Both ends of the crossbar at the upper end of the frame 1 are fixedly connected to electric hoists 9. Each electric hoist 9 has a gripping assembly 6 at its traction end for lifting pipes from the ground. The gripping assembly 6 includes a connecting box 64, with a hanger 61 fixedly connected to the upper end of the connecting box 64. The hanger 61 is connected to the traction end of the electric hoist 9. Connecting columns 65 are rotatably connected to both sides of the connecting box 64. Gears 62 are fixedly connected to the two connecting columns 65 inside the connecting box 64, and the two gears 62 mesh with each other. Arc-shaped clamps 63 are fixedly connected to both ends of each connecting column 65, and the upper ends of the arc-shaped clamps 63 are fixedly connected to… The electric hoist 9 is equipped with a drive arm 66, and a second electric cylinder 67 is provided between the ends of the drive arms 66 on both sides. The two ends of the second electric cylinder 67 are rotatably connected to the two drive arms 66 respectively. When it is necessary to lift the pipe on the ground, the electric hoist 9 first releases the gripping component 6, causing the gripping component 6 to descend. Then, the worker places the gripping component 6 on the pipe. At the same time, the second electric cylinder 67 starts to push the drive arm 66 to move. The movement of the drive arm 66 drives the arc-shaped clamping plate 63 to move accordingly, thereby gripping the pipe. The gear 62 is provided to make the arc-shaped clamping plates 63 on both sides move synchronously. After the pipe is gripped, the electric hoist 9 lifts the pipe.

[0043] The frame 1 is also fixedly connected to both sides with inverted U-shaped hollow frames 11, and the inverted U-shaped hollow frames 11 are provided with rotating components 5 for driving the pipe to rotate; the rotating components 5 include inverted U-shaped hollow frames 11, which are fixedly connected to both ends of the frame 1. Sliding plates 55 are slidably connected inside the two vertical rods of the inverted U-shaped hollow frames 11. Pulleys 56 are rotatably connected to the lower ends of the sliding plates 55 and the inverted U-shaped hollow frames 11. A drive belt 54 is installed between the four pulleys 56. Flat springs 59 are provided inside the two vertical rods of the inverted U-shaped hollow frames 11. An arc-shaped frame 57 is fixedly connected between the sides of the two sliding plates 55 away from the pulleys 56. A drive motor 53 for driving the pulleys 56 to rotate is fixedly connected to the lower end of the sliding plate 55 on one side of the inverted U-shaped hollow frames 11. Both sides of the inverted U-shaped hollow frame 11 are fixedly connected to side fixing brackets 52. The end of the side fixing bracket 52 away from the inverted U-shaped hollow frame 11 is fixedly connected to the two side rods of the frame 1. The lower end of the inverted U-shaped hollow frame 11 is fixedly connected to a reinforcing rod 58. During operation, after the pipe is lifted, the pipe will contact the drive belt 54 and push the drive belt 54 to move accordingly. At the same time, the sliding plate 55 will retract into the inverted U-shaped hollow frame 11 under the action of the flat spring 59. At this time, the lower end of the drive belt 54 forms a partial wrap around the pipe. The partial wrap can effectively ensure friction. Then, the drive motor 53 drives the pulley 56 to rotate. The rotation of the pulley 56 can drive the drive belt 54 to rotate. The rotation of the drive belt 54 can drive the pipe to rotate accordingly. Thus, the pipe can be rotated to a suitable position as needed when connecting the pipe.

[0044] A controller 13 is provided on one side of the frame 1, and a storage battery 10 for power supply is fixedly connected between the two crossbars at the upper end of the frame 1. The electric hoist 9, the storage battery 10, the third electric cylinder 71, the second electric cylinder 67, the first electric push rod 41, the drive motor 53 and the electromagnet 814 are all electrically connected to the controller 13. The storage battery 10 is used to control the various electrical components, thereby facilitating operation.

[0045] The working principle of this invention is as follows: During operation, the operator first pushes the frame 1 to the position of the pipe to be gripped. Then, the electric hoist 9 releases the gripping component 6, causing it to descend. The operator then places the gripping component 6 on the pipe. Simultaneously, the second electric cylinder 67 is activated to drive the drive arm 66. The drive arm 66 moves, causing the arc-shaped clamping plate 63 to move accordingly, thereby gripping the pipe. After the pipe is gripped, the electric hoist 9 lifts it up. When the pipe is lifted, it pushes the lifting arc plate 83 upward. The upward movement of the lifting arc plate 83 drives the T-shaped frame 86 upward. The upward movement of the T-shaped frame 86 drives the connecting rod 84 to move accordingly. The movement of the connecting rod 84 drives the support arm 89, thereby causing the two inclined sealing blocks 81 to flip and close. After closing, the locking component automatically locks the two inclined sealing blocks 81. The system supports the pipe, and when the pipe is lifted, it contacts the drive belt 54, causing the drive belt 54 to move accordingly. Simultaneously, the sliding plate 55 retracts into the inverted U-shaped hollow frame 11 under the action of the flat spring 59. At this time, the lower end of the drive belt 54 partially wraps around the pipe. Then, the frame 1 is moved to the required docking position, and the installed pipe is inserted into the docking block 14 and then fixed by the fixing component 4. After the fixing component 4 is fixed, it can restrict the frame 1 and prevent the frame 1 from moving arbitrarily. Then, the drive motor 53 drives the pulley 56 to rotate. The rotation of the pulley 56 drives the drive belt 54 to rotate, which in turn drives the pipe to rotate accordingly. Thus, when connecting the pipes, the pipes can be rotated to the appropriate position as needed, and then the two pipes can be connected accordingly.
