Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel rust removal, in particular to a steel rust removal device for building engineering. BACKGROUND

[0002] In the field of building engineering, steel as the core structural material, its surface rust problem directly affects the safety and durability of the engineering structure. Round steel as a common type of steel is widely used in reinforced concrete structure, steel structure support and other key parts, long-term exposure to humid, dusty construction environment, the surface is easy to form an oxide rust layer, if the rust layer is not removed in time, will lead to the round steel and concrete gripping force, reduce the structural bearing capacity, and even cause safety hazards, therefore, efficient, thorough rust removal treatment on the surface of round steel is an important pretreatment link before building engineering construction, and is also a basic process to ensure engineering quality.

[0003] The existing rust removal equipment lacks a linkage adaptive mechanism of rust layer thickness and polishing parameters. On the one hand, the equipment cannot accurately detect the rust layer thickness on the surface of the round steel, and it is difficult to adjust the polishing strategy according to the actual situation of the rust layer. On the other hand, the polishing pressure and speed are fixedly set. For round steel with uneven rust layer thickness, the thick rust area is easy to cause incomplete rust removal due to insufficient polishing force or speed, and the thin rust area may be damaged due to excessive polishing. This mode lacking dynamic adjustment cannot guarantee the consistency of the rust removal effect, and may cause waste of round steel or equipment loss, which seriously restricts the quality of rust removal operation.

A telescopic discharge pipe is fixedly connected inside the receiving ring, and the other end of the telescopic discharge pipe slides through the outer wall of the support plate.

[0018] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0019] This device can accurately detect the thickness of the rust layer, providing data support for grinding. In its detection mechanism, after the electromagnetic plate is de-energized, the arc-shaped magnetic block is attracted to the surface of the round steel by the elastic force of the plastic spring and its own magnetism. The thickness of the rust layer (non-magnetic material) determines the strength of the attraction force (the thicker the rust layer, the weaker the attraction force). When the electromagnetic plate is energized, its magnetic force gradually increases. When it overcomes the attraction force between the arc-shaped magnetic block and the round steel, the permanent magnet block drives the L-shaped conductive sheet to slide on the resistance plate, changing the circuit resistance. The current detector converts the resistance change into an electrical signal and transmits it to the PLC controller. By the difference in current value (the thicker the rust layer, the smaller the required current), the thickness of the rust layer is accurately determined, thereby avoiding blind grinding.

[0020] This device can adaptively adjust grinding parameters based on data detected by the testing agency, ensuring rust removal effectiveness while protecting the round steel. The PLC controller adjusts the grinding pressure and speed according to the detected rust thickness. Regarding grinding pressure, it controls the extension of the electric telescopic rod (extending longer for thick rust and shorter for thin rust). The pressure sensor monitors the pressure of the arc-shaped grinding disc on the round steel in real time and feeds it back to the PLC controller, continuously fine-tuning the electric telescopic rod to ensure the pressure is suitable for the rust thickness. Regarding grinding speed, when the rust layer is thick, the speed of the third drive motor is increased, and the gear meshes with the external gear ring, causing the rotating ring to drive the arc-shaped grinding disc to rotate at high speed. When the rust layer is thin, the speed of the third drive motor is reduced to decrease the grinding speed and avoid over-grinding. This achieves thorough rust removal in thick rust areas and avoids damage to the round steel in thin rust areas.

[0021] The device can perform automated segmentation processing, adapt to long round steel and improve efficiency. In the moving mechanism, the first and second drive motors drive the first and second threaded rods to rotate, so that the first connecting ring (detection mechanism) and the second connecting ring (grinding mechanism) move back and forth along the limit rod, covering the entire section of the round steel. The running time of the drive motor is preset to ensure that the detection and grinding cover the entire section of the round steel, and the detection and grinding positions correspond precisely (synchronization is ensured by the sliding cooperation of the limit rod and the support block). Thus, it can process long round steel without manual intervention for segmentation and realize continuous automated operation.

[0022] In summary, this device achieves automated and precise rust removal by dynamically linking rust thickness detection with grinding parameters (pressure and speed) through a closed-loop design of "detection-analysis-adjustment-execution". At the same time, the pretreatment mechanism, environmental optimization design, and stable conveying structure further improve the quality and efficiency of the operation.

[0043] Both support plates 2 have circular grooves 6 on their outer walls, and sliding grooves 7 are arranged in a circular array on the inner walls of both circular grooves 6.

[0044] A mounting ring 13 is fixedly connected to the outer wall of the support plate 2 at the feed point, and the mounting ring 13 faces another mounting plate. Multiple cleaning brushes 14 are fixedly connected to the inner circumferential wall of the mounting ring 13.

[0045] The working principle of this invention is as follows:

[0046] This steel rust removal device for construction projects is specifically designed for rust removal of round steel used in construction. Its operating principle revolves around the process of segmented conveying, inspection, and grinding to remove rust from the round steel. The various mechanisms work together to achieve automated operation, as detailed below:

[0047] The round steel is processed in a segmented conveying mode (because some round steel is too long to be processed in one segment). First, it passes through the circular groove 6 of the feed end support plate 2, the mounting ring 13, the first connecting ring 31, and the second connecting ring 41 in sequence from the feed end, and finally passes out from the circular groove 6 of the discharge end support plate 2.

[0048] When the round steel enters the device, the sliding block 9 in the circular groove 6 at the feed end, under the action of the connecting spring 8, drives the extrusion roller 12 on the mounting frame 10 to press tightly against the surface of the round steel. At the same time, the micro motor 11 starts and drives the rotating rod to rotate, so that the extrusion roller 12 rotates synchronously. This not only assists in the stable conveying of the round steel, but also crushes the loose rust layer through extrusion, preparing for subsequent rust removal. When the round steel passes through the mounting ring 13, the cleaning brush 14 on its inner wall will perform a preliminary cleaning of the surface of the round steel, removing floating dust, impurities and crushed loose rust pieces.

[0049] Once a section of round steel is delivered to the designated position, the operator starts the first drive motor 51 via the PLC controller. The first drive motor 51 drives the first threaded rod 53 to rotate. Since the first fixed frame 55 is threadedly connected to the first threaded rod 53, and under the limiting action of the limit rod 59, the first fixed frame 55 drives the first connecting ring 31 to move forward (the running time of the first drive motor 51 is preset to ensure that it can cover the entire section of round steel for inspection. After running for a period of time, it automatically shuts off, causing the first connecting ring 31 to stop moving for inspection. The stopping time is adjusted according to the actual inspection time).

[0050] After the first connecting ring 31 stops moving, the electromagnetic plate 33 inside the detection frame 32 is de-energized. Because the electromagnetic plate 33 and the permanent magnet block 35 are magnetically attracted, after the power is de-energized, under the action of the elastic force of the plastic spring 34 and the attraction force between the arc-shaped magnetic block 36 and the round steel, the permanent magnet block 35 drives the arc-shaped magnetic block 36 to be attracted to the surface of the round steel.

[0051] Because there is a rust layer between the arc-shaped magnetic block 36 and the round steel, the rust layer (mainly composed of non-magnetic substances such as iron oxide) will block the magnetic field of the arc-shaped magnetic block 36, causing the attraction force between the two to change with the thickness of the rust layer: the thicker the rust layer, the more obvious the magnetic field attenuation and the smaller the attraction force; the thinner the rust layer, the weaker the magnetic field blockage and the greater the attraction force.

[0052] Based on this characteristic, the PLC controller slowly energizes the electromagnetic plate 33, causing its magnetism to gradually attract the permanent magnet block 35 and the arc-shaped magnetic block 36. When the attraction force of the electromagnetic plate 33 is sufficient to overcome the attraction force between the arc-shaped magnetic block 36 and the round steel, the permanent magnet block 35 and the arc-shaped magnetic block 36 detach from the round steel. At the same time, the permanent magnet block 35 drives the L-shaped conductive sheet 38 to slide on the resistance plate 37, changing the resistance value of the detection circuit. The current detector transmits the electrical signal corresponding to the resistance change to the PLC controller, and the PLC controller records the magnitude of the current flowing through the electromagnetic plate 33 at this time.

[0053] The thicker the rust layer, the weaker the attraction between the arc-shaped magnetic block 36 and the round steel, and the electromagnetic plate 33 only needs a small current to detach it; the thinner the rust layer, the greater the current required. By the difference in current values, the thickness of the rust layer on the surface of the round steel can be indirectly determined. Then, by moving the mechanism, the detection mechanism 3 continues to move forward, and the detection continues as described above.

[0054] After the inspection is completed, the PLC controller starts the second drive motor 52 according to the rust layer thickness information, which drives the second threaded rod 54 to rotate. Under the limit of the limit rod 59, the second fixed frame 56 drives the second connecting ring 41 to move forward. After moving to the first inspection position, the second drive motor 52 is turned off (the running time of the second drive motor 52 is preset to be consistent with the running time of the first drive motor 51 to ensure that it can cover the entire section of the round steel for rust removal. After running for a period of time, it will automatically turn off, so that the second connecting ring 41 stops moving to remove rust. The stopping time is adjusted according to the actual rust removal time requirements). Then the third drive motor 45 is started, which drives the rotating ring 42 to rotate through the meshing of the gear 46 and the external gear ring 47.

[0055] During this process, the thickness of the rust layer is clearly related to the grinding pressure and speed, and is adaptively adjusted through a PLC controller.

[0056] Grinding pressure adjustment: When the detection structure indicates a thick rust layer, the PLC controller will control the electric telescopic rod 43 to extend a longer length, so that the arc-shaped grinding disc 44 applies greater pressure to the surface of the round steel. The pressure sensor monitors the grinding pressure in real time and feeds the signal back to the PLC controller. The controller continuously fine-tunes the extension and retraction of the electric telescopic rod 43 according to the feedback to ensure that the pressure is within a reasonable range suitable for thick rust layers and to ensure grinding effect. If the rust layer is thin, the PLC controller will control the electric telescopic rod 43 to extend a shorter length, reduce the pressure of the arc-shaped grinding disc 44 on the round steel, and avoid damage to the round steel body due to excessive pressure. The pressure sensor also provides real-time feedback to ensure that the pressure is suitable for thin rust layers.

[0057] Grinding speed adjustment: For areas with thicker rust layers, the PLC controller will increase the speed of the third drive motor 45, and through the transmission of gear 46 and external gear ring 47, the rotating ring 42 will drive the arc-shaped grinding disc 44 to rotate at a faster speed; when the rust layer is thinner, the PLC controller will reduce the speed of the third drive motor 45, reduce the rotation speed of the arc-shaped grinding disc 44, and ensure the rust removal effect.

[0058] During the grinding process, the water pump 410 supplies water to the water storage chamber of the fixed ring 48 through the telescopic hose 411, and then sprays clean water onto the grinding area through the spray head 49 to reduce dust and cool the area. The annular exhaust fan 412 on the inner wall of the outer toothed ring 47 extracts the rust dust generated during grinding through the telescopic discharge pipe 413 to keep the working environment clean.

[0059] After one section of round steel is processed, the device repeats the above process to transport, inspect, and grind and remove rust from the next section of round steel until the entire round steel is processed.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
