Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, specifically to a cutting device for gas pipeline installation. Background Technology

[0002] With the acceleration of urbanization and the adjustment of energy structure, natural gas, as a clean and efficient energy source, is increasingly being used, leading to a growing length and scale of gas pipelines. Pipeline installation is a crucial step in gas engineering, and cutting equipment is an indispensable tool in this process. In the past, gas pipeline cutting relied mainly on manual cutting or simple tools such as hand saws and torches. These methods were not only inefficient but also resulted in inconsistent cutting quality, poor cut precision, and problems such as burrs and uneven bevel angles. This created significant difficulties for subsequent pipeline welding and connection, impacting the overall quality and progress of the gas project. With the development of automation technology, cutting equipment has evolved towards automation and intelligence. Some cutting equipment now features automatic positioning, automatic adjustment of cutting parameters, and automatic completion of the cutting process. This not only improves cutting precision and efficiency but also reduces the impact of human factors, making the cutting quality more stable and reliable.

[0010] This invention provides a cutting device for gas pipeline installation. It has the following advantages: 1. The gas pipeline installation cutting equipment requires slight preheating of the pipeline before cutting to prevent pipe breakage due to sudden temperature changes caused by large temperature differences during direct cutting. The first electric slider is activated, indirectly moving the laser cutting head to the area to be cut. Then, the second high-pressure water pump is activated, drawing water stored at the bottom of the cutting chamber through a second water pipe into a connecting water tank. The water in the connecting water tank then enters the heating chamber through a third water pipe. The heating chamber heats the water inside before it enters the... Inside the unopened cooling chamber, the pipes are preheated by spraying water through nozzles before cutting. After preheating, laser cutting begins. During the cutting process, the heating chamber stops heating, and the cooling chamber starts cooling the water. Then, the valve is opened, and the cooled water enters the annular connecting pipe through the fifth water pipe. Finally, the laser cutting head is cooled through cooling nozzles and spray nozzles to prevent the laser cutting head from overheating after prolonged operation, which would affect the cutting effect. At the same time, the cooled water is sprayed onto the pipe being cut through the nozzles to prevent the pipe from overheating and being damaged during cutting.

[0011] 2. This gas pipeline installation cutting equipment, when in use, involves inserting the pipeline into the first guide port, second guide port, and inlet. Then, the first pneumatic piston rod is activated. The extension and retraction of the first pneumatic piston rod moves the first connecting block, which in turn moves the second connecting block. The second connecting block then moves the telescopic rod and the third connecting block. During this movement, the telescopic rod retracts simultaneously, causing the first sliding block to slide towards the pipeline within the second slide rail. The movement of the third connecting block moves the arc-shaped clamping plate until it tightly clamps the pipeline, thus enabling the cutting of different sizes. The pipe is clamped and fixed. When laser cutting is performed, the first motor is started. The drive shaft of the first motor rotates, which drives the drive gear to rotate. The drive gear rotates, which drives the driven gear ring to rotate. The driven gear ring rotates, which drives the rotating ring to rotate. The rotating ring rotates, which drives the clamping box to rotate. The clamping box rotates, which drives the clamped pipe to rotate. This allows the laser cutting head to cut the pipe from all directions, avoiding the tedious steps of manually rotating and adjusting the cutting angle, thus improving cutting efficiency. At the same time, it can clamp pipes of different sizes, further improving the adaptability of clamping.

[0012] 3. When using this gas pipeline installation cutting equipment, after clamping one end of the pipeline, before cutting, the other end of the pipeline needs to be supported and fixed. The second pneumatic piston rod is activated, its movable end extending and retracting, pushing the connecting rod along the sliding sleeve. At this time, the first and second connecting brackets move synchronously with the connecting rod and sliding sleeve. Through the scissor fork structure, the first and second rotating frames are driven to rotate around their respective first and second rotating rods. During rotation, the fourth connecting bracket drives the second sliding block to slide on the inner wall of the third slide rail, ultimately realizing the expansion or contraction of the support plate. This allows for support of pipelines of different sizes, preventing instability and cracks at the other end of the pipeline due to excessive length during cutting, thus affecting the cutting effect.

[0013] 4. The gas pipeline installation cutting equipment generates a lot of debris during use. The first high-pressure water pump is activated, drawing water from the bottom of the cutting chamber and transporting it through the first water pipe to the arc-shaped connecting pipe. The water is then sprayed out through the spray pipe. Simultaneously, the second electric slider is activated, sliding on the inner wall of the fourth slide rail, moving the arc-shaped slide rail along the pipeline. At the same time, the third pneumatic piston rod is activated, extending and retracting to move the arc-shaped connecting pipe. This movement of the arc-shaped connecting pipe moves the cleaning brush closer to the pipeline until the cleaning brush contacts the pipe. Stop moving the device, then activate the third electric slider. The third electric slider slides along the inner wall of the arc-shaped slide rail, indirectly driving the water spray pipe and cleaning brush to slide along the inner wall of the arc-shaped slide rail. Combined with the water sprayed from the water spray pipe, it scrubs the debris attached to the pipe, thus cleaning the pipe without dead corners and improving cleaning efficiency. The wastewater and debris after cleaning are filtered through the filter holes at the bottom of the inner wall of the recycling box. The filtered water returns to the bottom of the inner wall of the cutting box for water recycling. When the debris inside the recycling box reaches a certain amount, move the handle to pull out the recycling box, collect the debris, and then insert it back into the cutting box for the next recycling and filtration.

The rotating column 61, with one end away from the second connecting plate 62, passes through one side of the inner wall of the cutting box 2 and is rotatably connected to the inner wall of the cutting box 2. Multiple sets of the first connecting bracket 67 are provided and are triangularly symmetrically distributed on the connecting rod 66. Multiple sets of the second connecting bracket 68 are provided and are triangularly symmetrically distributed on the sliding sleeve 64.

[0022] In use, after clamping one end of the pipe, before cutting, the other end of the pipe needs to be supported and fixed. The second pneumatic piston rod 63 is activated, and its movable end extends and retracts, pushing the connecting rod 66 to slide along the sliding sleeve 64. At this time, the first connecting bracket 67 and the second connecting bracket 68 move synchronously with the connecting rod 66 and the sliding sleeve 64. Through the scissor fork structure, the first rotating frame 611 and the second rotating frame 612 are driven to rotate around their respective first rotating rod 69 and second rotating rod 610. During the rotation, the fourth connecting bracket 620 drives the second sliding block 618 to slide on the inner wall of the third slide rail 617, ultimately realizing the expansion or contraction of the support plate 616. This allows for the support of pipes of different sizes, preventing the other end of the pipe from becoming unstable and cracking due to excessive length during the cutting process, thus affecting the cutting effect.

[0023] Please see Figures 1-11 The present invention provides a technical solution: the cleaning device 7 includes a connecting ring 71, a fourth slide rail 72 fixedly connected to one side of the connecting ring 71, a second electric slider 73 slidably connected to the inner wall of the fourth slide rail 72, an arc-shaped slide rail 78 fixedly connected to the side of the second electric slider 73 away from the fourth slide rail 72, a third electric slider 79 slidably connected to the inner wall of the arc-shaped slide rail 78, a fixed end of a third pneumatic piston rod 74 fixedly connected to the side of the third electric slider 79 away from the arc-shaped slide rail 78, an arc-shaped connecting pipe 75 fixedly connected to the movable end of the third pneumatic piston rod 74, a water spray pipe 76 uniformly connected to the top of the arc-shaped connecting pipe 75, a cleaning brush 77 uniformly fixedly connected to the portion of the top of the arc-shaped connecting pipe 75 located on one side of the water spray pipe 76, the connecting ring 71 fixedly connected to one side of the inner wall of the cutting box 2, and one side of the arc-shaped connecting pipe 75 connected to the first water pipe 13.

[0024] During use, because cutting generates a lot of debris, the first high-pressure water pump 12 is activated. The first high-pressure water pump 12 draws water from the bottom of the inner wall of the cutting box 2 and transports it through the first water pipe 13 to the inside of the arc-shaped connecting pipe 75. Then, the water is sprayed out through the spray pipe 76. At the same time, the second electric slider 73 is activated. The second electric slider 73 slides on the inner wall of the fourth slide rail 72, driving the arc-shaped slide rail 78 to move along the pipe. Then, the third pneumatic piston rod 74 is activated. The third pneumatic piston rod 74 extends and retracts, driving the arc-shaped connecting pipe 75 to move. The movement of the arc-shaped connecting pipe 75 drives the cleaning brush 77 to move closer to the pipe until the cleaning brush 77 moves to contact the pipe and stops moving. Then, the third electric slider 79 is activated. The third electric slider 79 slides on the inner wall of the arc-shaped slide rail 78, indirectly driving the water spray pipe 76 and the cleaning brush 77 to slide along the inner wall of the arc-shaped slide rail 78. Combined with the water sprayed from the water spray pipe 76, the debris attached to the pipe is scrubbed, thus cleaning the pipe without dead corners and improving the cleaning efficiency. The wastewater and debris after cleaning are filtered through the filter hole 11 at the bottom of the inner wall of the recycling box 8. The filtered water returns to the bottom of the inner wall of the cutting box 2 for water recycling. When the debris inside the recycling box 8 reaches a certain amount, the handle 10 is moved to pull out the recycling box 8 to collect the debris, and then it is inserted back into the cutting box 2 for the next recycling and filtration.
