Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, specifically to a spark-proof device for steel pipe cutting. Background Technology

[0002] During steel pipe cutting (such as flame cutting, plasma cutting, laser cutting, or sawing), high-temperature sparks and molten slag splashing are common problems. These splashing sparks can not only pollute the surrounding environment but also easily injure operators. Therefore, spark protection devices are needed to protect against spark splashing.

[0003] A splash-proof, equidistant steel pipe cutting device, disclosed in CN222710944U, includes a housing. The housing comprises a base plate and multiple feet fixedly mounted at the bottom of the base plate. A receiving groove is provided at the top of the base plate, and a cutting device and a positioning device are located at the top of the base plate. The cutting device is located to one side of the positioning device and includes a cutting blade. A first baffle is fixedly mounted on the side of the cutting blade away from the receiving groove. This invention adjusts the steel pipe to a suitable position by pressing it against the positioning plate. Then, a telescopic motor drives a high-speed rotating cutting blade to cut the steel pipe. When the cutting blade moves downwards, the bottom end of the second baffle contacts the surface of the steel pipe. As the cutting blade continues to move, the second baffle slides within a first groove, ensuring that the bottom end of the second baffle remains in contact with the surface of the steel pipe, thus blocking sparks generated during cutting and preventing injury to the user's clothing and skin.

[0004] The device uses a baffle to block the flying sparks. However, when using the baffle to prevent the sparks from flying, the baffle cannot move with the cutting point. When the cutting position changes (especially when cutting long steel pipes continuously), about 30-40% of the sparks will splash out from the edge of the baffle, thus affecting the blocking effect.

[0005] To address the aforementioned issues, we have made innovative designs based on the existing structure of the anti-sparking device for steel pipe cutting. Utility Model Content

[0006] The purpose of this invention is to provide a spark-proof device for steel pipe cutting, in order to solve the problem mentioned in the background art that when using a baffle to prevent sparks from splashing, the baffle cannot follow the movement of the cutting point. When the cutting position changes (especially when cutting long steel pipes continuously), about 30-40% of the sparks will splash out from the edge of the baffle, thus affecting the shielding effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a spark-proof device for steel pipe cutting, comprising a base with an empty groove on its inner side; a cutting table fixedly installed on the upper end of the base; a support frame fixedly installed on the upper end of the base; a water curtain assembly disposed on the outer side of the base; a nozzle disposed on the upper end of the cutting table; and a locking assembly disposed on the outer side of the water curtain assembly; wherein the water curtain assembly is used to form a water curtain barrier to block the sparks generated during cutting; and the locking assembly is used to adjust the height of the nozzle.

[0008] Preferably, the water curtain assembly includes a circulating water tank, a circulating water pump, and an inlet pipe. The circulating water tank is fixedly installed on the outside of the support frame, and the circulating water pump is fixedly installed on the outside of the circulating water tank. The output end of the circulating water pump is fixedly connected to the inlet pipe.

[0009] Preferably, the water curtain assembly further includes a connector, a connecting pipe, a connecting tube, and a water tray. The connector is fixedly installed inside the support frame, and the top of the connector is connected to the water inlet pipe. The bottom of the connector is rotatably connected to the connecting pipe, and the connecting tube is slidably connected to the outside of the connecting pipe. The tail end of the connecting tube is fixedly connected to the water tray, and nozzles are equidistantly connected to the left and right sides of the water tray.

[0010] Preferably, the water curtain assembly further includes a first gear, a drive motor, and a second gear. The drive motor is fixedly installed on the outside of the support frame, and the output end of the drive motor is fixedly connected to the second gear. The second gear is meshed with the first gear on the outside, and the first gear is fixedly installed on the outside of the connecting pipe.

[0011] Preferably, the water curtain assembly further includes a water storage tank, a filter screen, and a water outlet pipe. The water storage tank is located inside the base, and a filter screen is fixedly connected to the bottom of the water storage tank. The bottom of the water storage tank is connected to a circulating water tank through the water outlet pipe.

[0012] Preferably, the engaging assembly includes slots that are equidistantly located on the outside of the connecting pipe.

[0013] Preferably, the engaging assembly further includes a telescopic spring and a locking rod. The locking rod is connected to the outside of the connecting tube via the telescopic spring, and the tail end of the locking rod penetrates the inside of the connecting tube and engages with the locking groove.

[0014] Compared with the prior art, the beneficial effect of this utility model is that the anti-sparking device for steel pipe cutting is equipped with:

[0015] 1. Water curtain shielding structure: When the steel pipe body is cut on the cutting table, the circulating water pump is run, so that the water inside the circulating water tank enters the connector, connecting pipe, butt pipe, water tray and nozzle in sequence through the water inlet pipe. The nozzle sprays the water into the left and right sides of the cutting table, thus forming a water curtain. The water curtain shields the sparks generated by cutting and prevents the sparks from splashing to both sides.

[0016] Furthermore, the water sprayed from the nozzles enters the inner side of the water storage tank, where impurities are intercepted by the filter screen. After the water is filtered, it enters the empty tank and then re-enters the inner side of the circulating water tank through the outlet pipe, thus recycling the water and achieving energy-saving effects.

[0017] Furthermore, when the cutting angle of the steel pipe body changes, the drive motor is operated, which causes the output end of the drive motor to drive the second gear to rotate. The rotation of the second gear will drive the outer meshing first gear to rotate. The rotation of the first gear will drive the connecting pipe to rotate inside the connector, thereby changing the placement position of the nozzle to adapt to different cutting angles of the steel body.

[0018] 2. Height Adjustment Structure: When the water curtain range needs to be adjusted, the locking rod is manually pulled outward to separate the tail end of the locking rod from the locking groove. After the tail end of the locking rod is separated from the locking groove, the connecting pipe is in an active state. At this time, the height of the nozzle can be adjusted by sliding the connecting pipe up and down along the outside of the connecting pipe. By adjusting the height of the nozzle, the height of the water curtain can be adjusted, thereby achieving the effect of adjusting the anti-sparking range to adapt to the cutting of steel pipes of different sizes.

[0027] Please see Figures 1-6 This utility model provides a technical solution: a spark-proof device for cutting steel pipes, comprising:

[0028] Example 1: As Figures 1-5 The present invention provides a technical solution for preventing sparks from splashing during steel pipe cutting, comprising: a base 1 with an empty groove 2 on its inner side; a cutting table 3 fixedly installed on the upper end of the base 1; a support frame 4 fixedly installed on the upper end of the base 1; a water curtain assembly 5 disposed on the outer side of the base 1; a nozzle 508 disposed on the upper end of the cutting table 3; and a locking assembly 6 disposed on the outer side of the water curtain assembly 5. The water curtain assembly 5 forms a water curtain barrier to block sparks generated during cutting; the locking assembly 6 adjusts the height of the nozzle 508.

[0029] The water curtain assembly 5 includes a circulating water tank 501, a circulating water pump 502, and an inlet pipe 503. The circulating water tank 501 is fixedly installed on the outside of the support frame 4, and the circulating water pump 502 is fixedly installed on the outside of the circulating water tank 501. The output end of the circulating water pump 502 is fixedly connected to the inlet pipe 503.

The bottom of the connector 504 is rotatably connected to the connecting pipe 505, and the connecting tube 506 is slidably connected to the outside of the connecting pipe 505. The tail end of the connecting tube 506 is fixedly connected to the water tray 507. Spray nozzles 508 are equidistantly connected to the left and right sides of the disc 507; the water curtain assembly 5 also includes a first gear 509, a drive motor 510 and a second gear 511. The drive motor 510 is fixedly installed on the outside of the support frame 4, and the output end of the drive motor 510 is fixedly connected to the second gear 511.

The bottom of the water storage tank 512 is connected to the circulating water tank 501 through the water outlet pipe 514;

[0030] When the steel pipe is cut on the cutting table 3, this structure operates a circulating water pump 502, causing water from the inside of the circulating water tank 501 to flow through the inlet pipe 503 into the connector 504, connecting pipe 505, connecting pipe 506, water tray 507, and nozzle 508. The nozzle 508 sprays the incoming water onto the left and right sides of the cutting table 3, forming a water curtain.

[0033] When the water curtain range needs to be adjusted, the locking rod 603 is manually pulled outward to separate the tail end of the locking rod 603 from the locking groove 601.
