Description

Technical Field

[0001] This utility model relates to the field of pipeline internal grinding technology, and in particular to an automated grinding equipment for pipeline internal welds used in smart construction sites. Background Technology

[0002] Water pipelines are the lifeline for the survival and development of cities and industrial enterprises. In recent years, with the urbanization process and industrial development, more and more long-distance water diversion and transmission projects have been put into production. Pipe materials are widely used in projects such as water diversion pipelines, raw water pipelines (from water source to water plant), clean water pipelines (from water plant to municipal water supply network), reclaimed water pipelines, sewage pipelines, seawater desalination pipelines, and dredging pipelines.

[0003] During pipe welding, a large number of weld points are generated inside the pipe. Traditional cleaning requires manual labor, which results in low cleaning efficiency. In addition, when performing anti-corrosion treatment on the inside of the pipe after cleaning, the grinding equipment needs to be removed, which greatly reduces work efficiency.

[0004] In view of this, this paper studies and improves existing problems to provide an automated grinding equipment for pipe internal welds in smart construction sites. The equipment has a reasonable structural design, high stability, and can be used in various aspects. The aim is to solve problems and improve practical value through this technology. Utility Model Content

[0005] This invention utilizes a liquid storage block that rotates to drive steel balls. Each time the steel balls rotate, they carry out some corrosion inhibitor through the empty groove, which flows onto the inner wall of the polished pipe. This provides corrosion and rust prevention treatment to the polished area, extending the service life of the pipe. This invention realizes an automated polishing equipment for pipe weld seams in smart construction sites.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an automated grinding device for pipe internal welds in smart construction sites, comprising a motor, a threaded rod for transmission provided inside the motor, a fixed rod fixedly connected to the end of the threaded rod away from the motor, a connecting pipe for quick connection fixedly connected to the outside of the fixed rod, a buckle for fixing the fixed rod fixedly connected to the inside of the connecting pipe, a push rod for controlling movement fixedly connected to one end of the buckle, a spring for resetting fixedly connected to the end of the push rod near the outside, and the threaded rod surrounding... The device is connected to a movable ring, and a liquid storage block for storage is fixedly connected to the periphery of the movable ring. A steel ball is movably connected to the outer side of the liquid storage block. A connecting block for connection is movably connected to the lower surface of the liquid storage block. A grinding disc for grinding is fixedly connected to the end of the connecting block away from the liquid storage block. A connecting rod for support is fixedly connected to the lower end of the grinding disc. An adjustment rope for adjustment is provided at the lower end of the connecting rod. A take-up reel for winding the pull rope is fixedly connected to one end of the connecting tube. An adjustment hole for adjusting the take-up reel is opened at the end of the take-up reel away from the connecting tube.

[0007] Preferably, the threaded rod is movably connected to the inside of the motor, and the threaded rod is driven to rotate by the motor. The fixed rod is fixedly connected to the outer surface of the threaded rod near the end of the connecting tube. The connecting tube is fixedly connected to the winding reel, and a slot is opened on the outside of the connecting tube. The size of the slot is larger than the outer diameter of the fixed rod.

[0008] Preferably, the buckle is movably connected to the end of the slot of the connecting tube via a push rod. The connecting tube retracts towards the rear end, and the push rod extends through the connecting tube to the outer end. A spring is fixedly connected to one end of the push rod near the outside. One end of the spring is fixedly connected to the push rod, and the other end is fixedly connected to the outer wall of the connecting tube.

[0009] Preferably, the movable ring is movably connected to the lower end of the four sets of liquid storage blocks. The inside of the liquid storage blocks is hollow and contains preservatives. The outer surfaces of the four sets of liquid storage blocks are movably connected with steel balls, and the outer surfaces of the steel balls are provided with slots.

[0010] Preferably, the lower end of the liquid storage block is fixedly connected to a connecting block, and the liquid storage block is connected to the connecting rod through the connecting block. The upper end of the connecting rod is fixedly connected to four grinding discs. Springs are provided on the periphery of the four sets of connecting rods. The lower end of the connecting rod is provided with a fixing block for positioning. The through hole opened inside the fixing block matches the outer diameter of the connecting rod and has a certain damping force.

[0011] Preferably, the height of the liquid storage block is controlled by the lifting and lowering of the connecting rod, the lower end of which is fixedly connected to a pull rope, the pull rope being fixedly connected to the lower winding reel, and the lifting and lowering of the connecting rod is controlled by the rotation of the winding reel to wind up the pull rope.

[0012] Preferably, the adjustment hole is connected to the shaft inside the winding reel, and the shaft of the winding reel can only be adjusted through the adjustment hole. When the winding reel rotates, the shaft will also rotate. The connecting pipe is fixedly connected to the outside of the winding reel, and when the connecting pipe moves, it will drive the winding reel to rotate synchronously.

[0013] This utility model has the following beneficial effects: Because the connecting pipe is connected to the winding reel, the connecting pipe will rotate when the motor drives the threaded rod to rotate. The rotation of the connecting pipe will drive the winding reel to rotate synchronously. The rotation of the winding reel will drive the grinding disc to rotate. At the same time, the grinding disc and the liquid storage block are connected through the connecting block. Therefore, the rotation of the grinding disc will drive the liquid storage block to rotate synchronously. When the liquid storage block rotates, the steel balls are movable inside, which makes the rotation of the liquid storage block smoother. At the same time, because the outer surface of the steel balls has a groove, each time the steel balls rotate, some of the anti-corrosion agent will be carried out and flow onto the inner wall of the polished pipe, thereby performing anti-corrosion and anti-rust treatment on the polished area and improving the service life of the pipe.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] Reference Figure 1-5 This utility model provides an embodiment of an automated grinding device for pipe internal welds used in smart construction sites, comprising a motor 1, a threaded rod 2 for transmission disposed inside the motor 1, a fixed rod 3 fixedly connected to the end of the threaded rod 2 away from the motor 1, a connecting pipe 4 for quick connection fixedly connected to the outside of the fixed rod 3, a buckle 5 for fixing the fixed rod 3 fixedly connected to the inside of the connecting pipe 4, a push rod 6 for controlling movement fixedly connected to one end of the buckle 5, a spring 7 for resetting fixedly connected to the end of the push rod 6 near the outside, and a movable ring 8 movably connected to the periphery of the threaded rod 2. A liquid storage block 9 is fixedly connected to the outer periphery of the ring 8. A steel ball 10 is movably connected to the outer side of the liquid storage block 9. A connecting block 11 is movably connected to the lower surface of the liquid storage block 9. A grinding disc 12 for grinding is fixedly connected to the end of the connecting block 11 away from the liquid storage block 9. A connecting rod 13 for support is fixedly connected to the lower end of the grinding disc 12. A pull rope 14 for adjustment is provided at the lower end of the connecting rod 13. A take-up reel 15 for winding the pull rope 14 is fixedly connected to one end of the connecting pipe 4. An adjustment hole 16 for adjusting the take-up reel 15 is opened at the end of the take-up reel 15 away from the connecting pipe 4.

[0024] In an optional embodiment: the threaded rod 2 is movably connected to the inside of the motor 1, and the threaded rod 2 is driven to rotate by the motor 1. The fixed rod 3 is fixedly connected to the outer surface of the threaded rod 2 near the end of the connecting pipe 4. The connecting pipe 4 is fixedly connected to the winding reel 15. A slot is opened on the outside of the connecting pipe 4. The size of the slot is larger than the outer diameter of the fixed rod 3. When the equipment enters the tube body, the threaded rod 2 is driven to rotate by the motor 1, thereby gradually advancing the equipment. At the same time, the extension and retraction of the equipment can be controlled by the forward and reverse rotation of the threaded rod 2 driven by the motor 1.

[0025] In an optional embodiment: the latch 5 is movably connected to the end of the slot of the connecting tube 4 via the push rod 6. The connecting tube 4 can retract to the rear end. The push rod 6 extends through the connecting tube 4 to the outer end. A spring 7 is fixedly connected to one end of the push rod 6 near the outside. One end of the spring 7 is fixedly connected to the push rod 6, and the other end is fixedly connected to the outer wall of the connecting tube 4. When the threaded rod 2 extends into the connecting tube 4, the fixing rod 3 on the outer surface of the threaded rod 2 will enter along the slot of the connecting tube 4. When it enters the slot of the connecting tube 4, the threaded rod 2 is rotated toward the latch 5. When the threaded rod 2 rotates, it will drive... The fixing rod 3 rotates synchronously. Since the fixing rod 3 is a cylinder and the contact surface between the buckle 5 and the fixing rod 3 is an inclined surface, the fixing rod 3 will squeeze the buckle 5 when it contacts the buckle 5, moving the buckle 5 to the rear end. As a result, the fixing rod 3 will gradually move. When the fixing rod 3 moves to the rear end of the buckle 5, since the rear end of the buckle 5 is an empty groove, the squeezing of the buckle 5 will be released. As a result, the buckle 5 will be reset by the push rod 6 pushed by the spring 7, fixing the fixing rod 3. When removing the screw rod 2, the buckle 5 is moved by pulling the push rod 6 to release the fixing of the fixing rod 3, thereby removing the screw rod 2.

[0026] In an optional embodiment: the movable ring 8 is movably connected to the lower end of four sets of liquid storage blocks 9. The liquid storage blocks 9 are hollow and contain preservatives. Steel balls 10 are movably connected to the outer surface of each of the four sets of liquid storage blocks 9. The outer surface of the steel balls 10 has slots. Because the connecting pipe 4 is connected to the winding reel 15, when the motor 1 drives the threaded rod 2 to rotate, it will drive the connecting pipe 4 to rotate. When the connecting pipe 4 rotates, it will drive the winding reel 15 to rotate synchronously. Because when the winding reel 15 rotates, it will drive the grinding disc 12 to rotate. The grinding disc 12 is connected to the liquid storage block 9 via the connecting block 11. Therefore, when the grinding disc 12 rotates, it will drive the liquid storage block 9 to rotate synchronously. When the liquid storage block 9 rotates, the steel ball 10 is connected inside, which makes the rotation of the liquid storage block 9 smoother. At the same time, because the outer surface of the steel ball 10 has a groove, each time the steel ball 10 rotates, it will carry out some anti-corrosion agent and flow into the inner wall of the pipe after grinding, thus performing anti-corrosion and anti-rust treatment on the ground area and improving the service life of the pipe.

[0027] In an optional embodiment: a connecting block 11 is fixedly connected to the lower end of the liquid storage block 9, and the liquid storage block 9 is connected to the connecting rod 13 through the connecting block 11. A grinding disc 12 is fixedly connected to the upper end of the connecting rod 13, and there are four sets of them. Springs 7 are provided on the periphery of the four sets of connecting rods 13. A fixing block for positioning is provided at the lower end of the connecting rod 13. The through hole opened inside the fixing block matches the outer diameter of the connecting rod 13 and has a certain damping force to prevent the connecting rod 13 from jumping up and down continuously due to the protrusion inside the pipe during grinding, which would cause its running trajectory to be unstable. At the same time, when the connecting rod 13 jumps, it will also make it impossible to grind the position of the protrusion.

[0028] In an optional embodiment: the height of the liquid storage block 9 is controlled by the lifting and lowering of the connecting rod 13. The lower end of the connecting rod 13 is fixedly connected to the pull rope 14, and the pull rope 14 is fixedly connected to the lower end of the winding reel 15. The lifting and lowering of the connecting rod 13 is controlled by the rotation of the winding reel 15 to wind up the pull rope 14. When the winding reel 15 rotates, it will drive the pull rope 14 to retract synchronously. Since the pull rope 14 is connected to the connecting rod 13, the retraction of the pull rope 14 will pull the connecting rod 13 down, thereby driving the grinding disc 12 down, thereby adjusting the outer diameter of the grinding disc 12 to adapt to pipes with different inner diameters. At the same time, when the winding reel 15 releases the pull rope 14, the connecting rod 13 will gradually rise due to the force of the spring 7 because there is a certain damping force between the connecting rod 13 and the fixed block.

[0029] In an optional embodiment: the adjustment hole 16 is connected to the shaft inside the winding reel 15, and the shaft of the winding reel 15 can only be adjusted through the adjustment hole 16. When the winding reel 15 rotates, the shaft will also rotate. The connecting pipe 4 is fixedly connected to the outside of the winding reel 15. When the connecting pipe 4 moves, it will drive the winding reel 15 to rotate synchronously, so that when the threaded rod 2 rotates, it can drive the front end to rotate synchronously. At the same time, the pull rope 14 will not be loosened due to the rotation.

[0030] Working principle and process: Before use, the operator uses a tool to rotate the adjustment hole 16 to adjust the outer diameter of the grinding disc 12 to match the inner diameter of the pipe. When adjusting the grinding disc 12, the grinding disc 12 will drive the liquid storage block 9 to move synchronously. Then, the threaded rod 2 is connected to the connecting pipe 4, and the equipment is placed inside the pipe. The motor 1 drives the threaded rod 2 to rotate, thereby driving the equipment to rotate for grinding. When the liquid storage block 9 rotates, the steel ball 10 will rotate synchronously. At the same time, the steel ball 10 will continuously carry out the corrosion inhibitor when rotating, thereby performing anti-corrosion treatment on the inner wall of the pipe.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
