[0002] Compared with other material structures, steel structure has high mechanization degree in manufacturing and installation, and can achieve complete sealing after welding. At present, steel structure is widely used in factory manufacturing and building components. Most importantly, steel structure building itself does not produce construction waste after being demolished and can be recycled.

[0003] A steel pipe rust removal machine is disclosed in Chinese patent application No. CN202211391948.5, which comprises a base and a clamping mechanism.

[0043] As shown in Figures 1 to 11 The cylindrical rust removal machine of the present application comprises a rack 1, a fixing mechanism 2 for fixing a steel pipe, a rust removal mechanism 3 for rust removal of the fixed steel pipe, and a maintenance mechanism 4 for maintenance of the rust-removed steel pipe.

[0044] The fixing mechanism 2 comprises a power source I 22 fixedly installed on the rack 1, a first chuck 21 fixedly installed on the output end of the power source I 22, a fourth linear module 25 fixedly installed on the rack 1, a mounting seat 23 fixedly installed on the rack 1, and a second chuck 24 rotatably installed on the mounting seat 23.

[0045] When the steel pipe is rusted, the steel pipe is first fixed, at which time the steel pipe is placed between the first chuck 21 and the second chuck 24, and the fourth linear module 25 is started to drive the mounting seat 23 to move, the mounting seat 23 drives the second chuck 24 to move, so that the distance between the first chuck 21 and the second chuck 24 can be adjusted according to the length of the steel pipe, thereby improving the convenience of use, and the interior of the steel pipe is clamped and fixed by the first chuck 21 and the second chuck 24. After the fixing is completed, the rust removal mechanism 3 can be started to perform rust removal operation.

[0046] It is supplemented here that the first chuck 21 and the second chuck 24 are preferably three-jaw chucks, which belong to the prior art, so no further description is made here; and different diameter steel pipes can be clamped and fixed through the first chuck 21 and the second chuck 24, so that the adaptability is improved;

[0047] The power source one 22 is preferably a motor.

[0048] The rust removal mechanism 3 comprises: a first linear module 31 mounted on the rack 1; a second linear module 32 mounted on the first linear module 31; a mounting box 33 fixedly mounted on the second linear module 32; a polishing cylinder 34 rotatably mounted in the mounting box 33; a power source two 35 for driving the polishing cylinder 34 to rotate, which is fixedly mounted on the mounting box 33; and a collection assembly 36 for collecting the generated waste during polishing.

[0049] When the steel pipe is fixed, the power source one 22 is started to drive the first chuck 21 to rotate, so as to drive the steel pipe to rotate, thereby facilitating the rust removal of the circumference of the steel pipe.

[0050] Meanwhile, the second linear module 32 is started to drive the mounting box 33 to move, and the mounting box 33 drives the polishing cylinder 34 to abut against the surface of the steel pipe, while the power source two 35 is started to drive the polishing cylinder 34 to rotate, so as to remove the rust on the surface of the steel pipe.

[0051] The first linear module 31 is started to drive the second linear module 32 to move, so as to drive the polishing cylinder 34 to move along the axial direction of the steel pipe, thereby facilitating the rust removal of the axial direction of the steel pipe.

[0052] In the present application, the fixing mechanism 2 and the rust removal mechanism 3 are arranged, so as to facilitate the rust removal of the axial direction and the circumference of the steel pipe, thereby realizing the comprehensive rust removal of the steel pipe and improving the rust removal effect.

[0053] It is supplemented here that the power source two 35 is preferably a motor.

[0054] The collection assembly 36 comprises: a collection hopper 362 insertedly mounted at the bottom of the mounting box 33; a collection box 361 in communication with the collection hopper 362; an electromagnet 363, a filter screen 364 and a gas pump 365 fixedly mounted in the collection box 361; a spray head 366 hingedly mounted in the mounting box 33; and a gas guide pipe 367 in communication with the gas pump 365 and the spray head 366.

[0055] When the polishing cylinder 34 removes the rust on the steel pipe, the gas pump 365 and the electromagnet 363 are started, and the waste generated during polishing is thrown into the mounting box 33 when the polishing cylinder 34 rotates, and is collected into the collection box 361 through the collection hopper 362, so as to avoid the waste from scattering in the working area and causing environmental pollution.

[0056] At the same time, the air pump 365 sucks the gas in the collecting box 361, so that the negative pressure is formed in the collecting box 361, and the air flow in the mounting box 33 drives the waste to quickly enter the collecting box 361, thereby improving the collection efficiency of the waste.

[0057] And the air pump 365 is delivered to the spray head 366 through the air pipe 367, and the gas sprayed in the spray head 366 can blow the waste in the mounting box 33 downward, thereby accelerating the air flow in the mounting box 33, and further improving the collection efficiency of the waste.

[0058] In the present application, by the setting of the collecting assembly 36, the lower air suction and upper air blowing mode is adopted, the air flow in the mounting box 33 is accelerated, and the collection efficiency of the waste is improved.

[0059] Through the setting of the filter screen 364, the air entering the air pump 365 can be filtered, so that the waste is retained in the collecting box 361, and the gas sprayed in the spray head 366 is filtered gas, thereby avoiding secondary pollution to the mounting box 33.

[0060] Through the setting of the electromagnet 363, during the rust removal process, the electromagnet 363 is electrified and generates magnetism, the waste entering the collecting box 361 is rust, and thus can be attracted by the electromagnet 363, on the one hand, the waste is not easy to float out after entering the collecting box 361, and the waste is better collected, on the other hand, the waste is reduced to adhere to the filter screen 364, and the filter screen 364 is blocked.

[0061] Here, it is supplemented that the sealing door is installed on the collecting box 361, when the rust removal is completed, the electromagnet 363 is de-energized, at this time, the sealing door is opened, and the waste in the collecting box 361 can be treated.

[0062] The rust removal mechanism 3 further comprises a cleaning assembly 38 for cleaning the filter screen 364; the cleaning assembly 38 comprises a baffle 381 hingedly installed in the collecting box 361, a torsional spring is installed at the hinge of the baffle 381 and the collecting box 361, and an iron sheet is fixedly installed on the bottom of the baffle 381 away from the hinge; a fixed rod 385 fixedly installed in the collecting box 361; a brush 384 slidingly installed on the fixed rod 385; a return spring 386 driving the brush 384 to return, one end of the return spring 386 is fixedly connected with the brush 384, and the other end is fixedly connected with the inner wall of the collecting box 361; a connecting rope 382 fixedly installed between the brush 384 and the baffle 381; a transmission wheel 383 rotatably installed in the collecting box 361, a guide groove is formed on the surface of the transmission wheel 383, and the connecting rope 382 is movably installed in the guide groove of the transmission wheel 383.

[0063] When the rust removal operation is not performed, the electromagnet 363 is not powered, i.e. the initial state, the baffle 381 is tightly attached to the top of the inner cavity of the collecting box 361 under the elastic force of the torsion spring, so that the bottom of the collecting hopper 362 can be closed, so that the collected waste in the collecting box 361 cannot be blown out of the collecting box 361, which affects the collecting effect.

[0064] When the electromagnet 363 is powered, the iron sheet on the baffle 381 is magnetically attracted by the electromagnet 363, and the baffle 381 rotates downward with the hinge of the baffle 381 and the collecting box 361 as the center, i.e. the side of the baffle 381 on which the iron sheet is installed rotates downward and approaches the electromagnet 363, at this time the baffle 381 does not have a closing effect on the collecting hopper 362, and the air shell of the mounting box 33 enters the collecting box 361.

[0065] When the baffle 381 rotates downward, the connecting rope 382 can be moved, and the connecting rope 382 drives the brush 384 to move upward under the driving action of the transmission wheel 383, and drives the return spring 386 to be compressed, at this time the limiting action of the two fixed rods 385 makes the brush 384 always abut against the filter screen 364.

[0066] When the rust removal is completed, the electromagnet 363 is powered off, and the attraction to the iron sheet is released, at this time the baffle 381 can be reset by the elastic force of the torsion spring, at the same time, the return spring 386 drives the brush 384 to reset downward, and the brush 384 can clean the filter screen 364 during the resetting process, so as to avoid the waste from blocking the filter screen 364 and affecting the filtering effect.

[0067] The rust removal mechanism 3 further comprises a cleaning assembly 37 for cleaning the polishing cylinder 34.

[0068] When the polishing cylinder 34 rotates, the brush roller 371 is driven to rotate by the linkage 372, and the waste attached to the surface of the polishing cylinder 34 can be cleaned and fallen off by the rotation of the brush roller 371, so as to avoid the waste from re-attaching to the surface of the steel pipe due to the rotation of the polishing cylinder 34, which causes incomplete rust removal and affects the surface quality of the steel pipe, so that the polishing cylinder 34 can better remove rust from the steel pipe.

[0069] It is supplemented here that the linkage 372 is preferably a synchronous belt and a synchronous wheel.

[0070] As a further extension of the present application, after the steel pipe is rusted, the rusted steel pipe needs to be coated with rust-proof maintenance liquid to ensure the rust removal quality.

[0071] The maintenance mechanism 4 comprises: a liquid storage tank 41 fixedly installed on the second linear module 32; a mounting shell 43; an adsorbing and smearing body 44 rotatably installed in the mounting shell 43; a third linear module 42 for moving the mounting shell 43, the third linear module 42 being fixedly installed on the top of the liquid storage tank 41; a delivery assembly 45 for delivering the maintenance liquid in the liquid storage tank 41 to the adsorbing and smearing body 44; the delivery assembly 45 comprising: a fixed pipe 451 fixedly installed in the liquid storage tank 41; a first piston 452 slidably installed in the fixed pipe 451; a power source three 453 for moving the first piston 452, the power source three 453 being fixedly installed in the fixed pipe 451; a capsule 454 fixedly installed between the first piston 452 and the fixed pipe 451; a liquid inlet pipe 455 in communication with the capsule 454, the liquid inlet pipe 455 being provided with a first one-way valve; a dispersion pipe 458 in communication with the mounting shell 43; a liquid outlet pipe 456 in communication between the capsule 454 and the dispersion pipe 458, the liquid outlet pipe 456 being provided with a second one-way valve.

[0072] When the polishing cylinder 34 moves along the axial direction of the steel pipe to remove rust, the third linear module 42 is started to move the mounting shell 43, so that the adsorbing and smearing body 44 abuts against the surface of the steel pipe on which the rust removal is completed, and since the adsorbing and smearing body 44 is in the form of a roller, it can rotate along with the rotation of the steel pipe.

[0073] At the same time, the power source three 453 is started to move the first piston 452 to reciprocate up and down in the fixed pipe 451, and to compress or restore the capsule 454, when the capsule 454 is restored, the first one-way valve is opened and the second one-way valve is closed, at this time, the maintenance liquid in the liquid storage tank 41 enters the capsule 454 through the liquid inlet pipe 455, when the capsule 454 is compressed, the second one-way valve is closed and the first one-way valve is opened, at this time, the maintenance liquid in the capsule 454 is squeezed to enter the dispersion pipe 458 through the liquid outlet pipe 456, and is sprayed on the adsorbing and smearing body 44, after the adsorbing and smearing body 44 absorbs the maintenance liquid, it rotates along with the rotation of the steel pipe, so that the maintenance liquid can be smeared on the surface of the steel pipe, and the rust removal quality of the steel pipe is ensured.

[0074] The dispersion pipe 458 is fixedly installed with a dispersion plate 459, and a plurality of circular holes are formed in the dispersion plate 459; the maintenance liquid entering the dispersion pipe 458 can be uniformly sprayed on the adsorbing and smearing body 44 through the dispersion plate 459, so that the adsorbing and smearing body 44 can uniformly smear the maintenance liquid on the surface of the steel pipe.

[0075] It is supplemented here that the power source three 453 is preferably a telescopic cylinder; the material of the adsorbing and smearing body 44 is sponge.

[0076] The fixed tube 451 has several through holes 457. The power source 453 drives the first piston 452 to move up and down reciprocally inside the fixed tube 451. When the first piston 452 moves upward, the maintenance liquid in the storage tank 41 enters the fixed tube 451 through the several through holes 457. When the first piston 452 moves downward, the maintenance liquid in the fixed tube 451 is sprayed into the storage tank 41 through the several through holes 457. This achieves the effect of uniformly mixing the maintenance liquid in the storage tank 41, avoiding the problem of precipitation of the maintenance liquid, which would lead to uneven distribution of the components of the maintenance liquid and affect the maintenance effect.

[0077] In this invention, by setting up the maintenance mechanism 4, on the one hand, the maintenance liquid in the storage tank 41 is mixed evenly, avoiding the problem of precipitation of the maintenance liquid, which would lead to uneven distribution of the components of the maintenance liquid and affect the maintenance effect; on the other hand, the maintenance liquid is evenly applied to the surface of the steel pipe, ensuring the quality of rust removal of the steel pipe.

[0078] The rust removal mechanism 3 also includes: a swing assembly 39 that drives the nozzle 366 to swing; the swing assembly 39 includes: a gas collecting pipe 392 that is inserted and installed on the mounting box 33; a connecting pipe 391 that connects the gas collecting pipe 392 and the fixed pipe 451; a second piston 393 that is slidably installed in the gas collecting pipe 392; a connecting rod 394 that is fixedly connected to the second piston 393; a linkage rod 395 that is hinged to the connecting rod 394; and a linkage spring 396 that drives the second piston 393 to reset, one end of the linkage spring 396 being fixedly connected to the second piston 393 and the other end being fixedly connected to the inner wall of the gas collecting pipe 392; a limit hole is provided on the gas collecting pipe 392, and the connecting rod 394 is slidably installed in the limit hole.

[0079] The first piston 452 divides the fixed tube 451 into two independent spaces, upper and lower. The space below the first piston 452 is connected to the through hole 457. By moving the first piston 452 up and down, the maintenance liquid in the storage tank 41 can be mixed. The space above the first piston 452 stores gas.

[0080] When the first piston 452 moves upward, it can compress the gas in the fixed tube 451 and transport it to the gas collecting tube 392 through the connecting tube 391. After the gas pressure in the gas collecting tube 392 increases, it pushes the second piston 393 and drives the linkage spring 396 to compress. At this time, the second piston 393 drives the connecting rod 394 to move, the connecting rod 394 drives the linkage rod 395 to move, and the linkage rod 395 drives the nozzle 366 to deflect.

[0081] When the first piston 452 moves downward, it can draw the gas in the gas collecting pipe 392 into the fixed pipe 451. At this time, the second piston 393 can be reset by the elastic force of the linkage spring 396, which in turn can reset the nozzle 366.

[0082] Through the above, through the reciprocating movement of the first piston 452, the reciprocating swing of the nozzle 366 can be realized, thereby improving the jet range of the nozzle 366, so that the high-pressure gas delivered by the air pump 365 can not only accelerate the air flow in the installation box 33, but also be sprayed on the brush roller 371 and the polishing cylinder 34, thereby realizing the cleaning of the surface debris of the brush roller 371 and the polishing cylinder 34.
