Technical Field
[0001] This utility model belongs to the field of cement pipe processing technology, specifically a device for grinding protrusions on the outer wall of reinforced concrete cement pipes. Background Technology
[0002] Reinforced concrete cement pipes are cement pipes mainly made by splicing two layers of shaped steel membranes into a column shape, then injecting concrete and vibrating to set the shape.
[0003] During the production of cement pipes, raw materials such as cement, sand, gravel and water need to be mixed and stirred. The prepared concrete is then fed into a mold for molding. During production, processing or use, bulges may appear on the outer wall of the cement pipe. The surface of the cement pipe needs to be polished to keep it smooth.

[0023] like Figures 1 to 4As shown, an embodiment of the present invention provides a grinding device for protrusions on the outer wall of a reinforced concrete cement pipe, comprising a base 1; two fixing plates 10 are fixedly connected to the top of the base 1; the two fixing plates 10 are arranged opposite each other; a telescopic rod 11 is fixedly connected to the side wall of the fixing plate 10; a first motor 12 is fixedly connected to the end of the telescopic rod 11; a moving rod 13 is fixedly connected to the output end of the first motor 12; the moving rod 13 is slidably connected to the middle of the fixing plate 10; an adjusting plate 14 is fixedly connected to the end of the moving rod 13; an adjusting groove 15 is provided in the middle of the adjusting plate 14; a bidirectional screw rod 17 is rotatably connected to the middle of the adjusting groove 15; a through groove 16 is provided in the side wall of the adjusting plate 14; the through groove 16 is located at the position corresponding to the adjusting groove 15; one end of the bidirectional screw rod 17 passes through... The middle of the adjusting plate 14 is threaded; two square nuts 18 are threadedly connected to the middle of the double-acting screw 17; the square nuts 18 are slidably connected to the middle of the adjusting groove 15; a connecting rod 19 is fixedly connected to the middle of the square nuts 18; a top plate 111 is fixedly connected to the end of the connecting rod 19; the top plate 111 is arc-shaped; an adjusting rod 8 is slidably connected to the side wall of the fixing plate 10; a second motor 81 is fixedly connected to the end of one of the adjusting rods 8; a grinding wheel 82 is fixedly connected to the output end of the second motor 81; the end of the other adjusting rod 8 is rotatably connected to one end of the grinding wheel 82; a support assembly 2 is provided on the top of the base 1; when grinding the cement pipe, the cement pipe is first placed on the support assembly 2, and supported by the support assembly 2, and... Move the device between the two adjusting plates 14, push the moving rod 13 to slide it in the middle of the fixed plate 10, and move the two adjusting plates 14 towards the cement pipe. At the same time, the telescopic rod 11 extends and retracts with the movement of the first motor 12 and the moving rod 13, moving the two top plates 111 into one end of the cement pipe. At this time, rotate the double-acting screw 17, and the two square nuts 18 slide to both sides inside the adjusting groove 15 through the double-acting screw 17, driving the top plates 111 to move to the inner wall of the cement pipe. The top plates 111 press against the inner wall of the cement pipe to fix it. Adjust the grinding wheel 82 through the adjusting rod 8 to make the grinding wheel 82 fit against the cement pipe. At the same time, turn on the second motor 81 and the first motor 12. The machine 81 drives the grinding wheel 82 to rotate at high speed, grinding the outer wall of the cement pipe. At the same time, the output end of the first motor 12 drives the moving rod 13 to rotate, controlling the first motor 12 to rotate the cement pipe.

It can also make the protruding parts of the outer wall of the cement pipe uniformly and comprehensively grind, reduce the situation of missing or over-grinding some areas, and achieve comprehensive grinding of the outer side of the cement pipe.
[0024] like Figure 1 and Figure 4As shown, the support assembly 2 includes two mounting slots 25; the two mounting slots 25 are formed on the top of the base 1; an electric actuator 21 is installed in the middle of the mounting slot 25; a support plate 22 is fixedly connected to the output end of the electric actuator 21; the support plate 22 is arc-shaped; multiple rotating slots 23 are formed in the middle of the support plate 22; the rotating slots 23 are evenly distributed; a roller 24 is rotatably connected to the middle of the rotating slot 23; during operation, the cement pipe is first placed in the two support plates 22, and the cement pipe contacts the multiple rollers 24. After the electric actuator 21 is energized, it is turned on, controlling the output of the electric actuator 21. The outlet moves upward, thereby moving the cement pipe to a designated height. During the grinding and rotation of the cement pipe, the roller 24 rotates in the middle of the rotating groove 23 as the cement pipe rotates. The above structure can effectively disperse the pressure generated on the top plate 111 during the grinding process and provide stable support for the cement pipe during grinding. Stable support can effectively improve the safety of grinding operations and effectively extend the service life of the overall components. The electric push rod 21 can more conveniently place the cement pipe in the designated position, reducing the problem of difficult handling.
[0025] like Figure 1 and Figure 4 As shown, a support rod 3 is fixedly connected to the end of the electric actuator 21; a fixing rod 31 is fixedly connected to the end of the two support rods 3; a brush plate 32 is fixedly connected to the middle of the fixing rod 31. During operation, when the two electric actuators 21 move upward, they drive the fixing rod 31 to move upward simultaneously. When the cement pipe is placed in the middle of the two support plates 22, the brush plate 32 adheres to the surface of the cement pipe. When the cement pipe rotates and is being polished, the dust adhering to the surface of the cement pipe is removed by the brush plate 32. The above structure effectively removes the dust and impurities adhering to the surface of the cement pipe during the polishing process, making the polished surface cleaner and smoother. The cleaned cement pipe surface can reduce the amount of dust adhering to the polishing wheel 82, thereby improving the polishing efficiency and effect, and allowing the polishing wheel 82 to maintain uniform contact and pressure during the polishing process, achieving a more uniform polishing effect.
[0026] like Figure 1 and Figure 4As shown, a water pump 4 is installed on the top of the base 1; an inlet pipe 41 is fixedly connected to the middle of the water pump 4; an outlet pipe 42 is fixedly connected to the middle of the water pump 4; the end of the outlet pipe 42 is fixedly connected to the middle of the fixing rod 31; the inside of the fixing rod 31 is a cavity; two sets of spray heads 43 are fixedly connected to the middle of the fixing rod 31; the two sets of spray heads 43 are arranged opposite each other; during operation, the inlet pipe 41 is connected to the water source, the water pump 4 is turned on, and water is discharged to the middle of the outlet pipe 42. The water flows through the outlet pipe 42 and into the interior of the fixing rod 31, forming a water mist through multiple spray heads 43 and spraying it onto the working area. The water mist combines with the dust generated during the grinding process, causing the dust in the air to settle. Through the above structure, the water mist can quickly reduce the temperature of the outer wall of the cement pipe in the grinding area, reducing the damage to the cement pipe caused by high temperature. A large amount of dust is generated during the grinding process. The water mist sprayed by the spray heads 43 can effectively adsorb and settle this dust, reducing the harm of dust to the working environment and workers.
[0027] like Figure 1 and Figure 4 As shown, a collection box 5 is installed on the top of the base 1; a filter plate 51 is fixedly connected to the middle of the collection box 5; during operation, dust falls and is collected uniformly through the collection box 5, and dust and water mist are filtered through the filter plate 51. The filter plate 51 intercepts large dust particles. The above structure can effectively collect the dust that settles during the grinding process, effectively reduce the dust from spreading around the working area, keep the working environment clean, and filter moisture and dust particles for subsequent unified treatment.
[0028] like Figure 3 As shown, a rubber pad 6 is fixedly connected to the middle of the top plate 111; the rubber pad 6 is fixedly connected to the side away from the connecting rod 19; during operation, when the top plate 111 supports the inner wall of the cement pipe, the rubber pad 6 contacts and fits tightly with the inner wall of the cement pipe. The above structure can effectively reduce the wear between the top plate 111 and the inner wall of the cement pipe, effectively reduce the excessive pressure of the top plate 111 on the inner wall of the cement pipe, and reduce the damage to the cement pipe during grinding.
[0029] like Figure 4 As shown, an elastic cloth 7 is fixedly connected to the middle of the support plate 22; the end of the elastic cloth 7 is fixedly connected to the middle of the electric actuator 21; the support rod 3 passes through the middle of the elastic cloth 7; during operation, when the electric actuator 21 moves the cement pipe, the elastic cloth 7 simultaneously expands and contracts elastically with the electric actuator 21, and the elastic cloth 7 isolates the dust from the output end of the electric actuator 21. The above structure can effectively reduce the dust adhering to the surface of the electric actuator 21, effectively reduce the dust entering the electric actuator 21 and accumulating inside, and reduce the wear caused by dust accumulation inside the electric actuator 21.
[0030] During operation, when grinding the cement pipe, the cement pipe is first placed on the support assembly 2 for support, and then moved between the two adjusting plates 14. The moving rod 13 is pushed to slide in the middle of the fixed plate 10, and the two adjusting plates 14 move towards the cement pipe. Simultaneously, the telescopic rod 11 extends and retracts with the movement of the first motor 12 and the moving rod 13, moving the two top plates 111 into one end of the cement pipe. At this point, the double-acting screw 17 is rotated, and the two square nuts 18 slide to both sides inside the adjusting groove 15 via the double-acting screw 17, causing the top plates 111 to move to the inner wall of the cement pipe. The cement pipe is fixed by the top plate 111 pressing against its inner wall. The grinding wheel 82 is adjusted by the adjusting rod 8 to make it fit against the cement pipe. At the same time, the second motor 81 and the first motor 12 are turned on. The second motor 81 drives the grinding wheel 82 to rotate at high speed, grinding the outer wall of the cement pipe. Simultaneously, the output end of the first motor 12 drives the moving rod 13 to rotate, controlling the first motor 12 to rotate the cement pipe. First, the cement pipe is placed between the two support plates 22, and the cement pipe is in contact with multiple rollers 24. The electric actuator 21 is then energized and turned on, controlling the output of the electric actuator 21. The outlet end moves upward, thus moving the cement pipe to a designated height. During the grinding and rotation of the cement pipe, the roller 24 rotates in the middle of the rotating groove 23 as the cement pipe rotates. When the two electric push rods 21 move upward, they drive the fixed rod 31 to move upward simultaneously. When the cement pipe is placed in the middle of the two support plates 22, the brush plate 32 adheres to the surface of the cement pipe. When the cement pipe rotates and is ground, the brush plate 32 removes the dust adhering to the surface of the cement pipe. The water inlet pipe 41 is connected to the water source, the water pump 4 is turned on, and water is discharged to the middle of the water outlet pipe 42. The water flows through the water outlet pipe 42 and into the interior of the fixed rod 31. Multiple spray nozzles 43 form water mist that is sprayed onto the working area. The water mist combines with the dust generated during the grinding process, causing the dust in the air to settle. After the dust settles, it is collected by the collection box 5. The dust and water mist are filtered through the filter plate 51, which intercepts large dust particles. When the top plate 111 supports the inner wall of the cement pipe, the rubber pad 6 contacts and fits tightly against the inner wall of the cement pipe. When the electric actuator 21 moves the cement pipe, the elastic cloth 7 elastically expands and contracts with the electric actuator 21, isolating the dust from the output end of the electric actuator 21.
