Description

Technical Field

[0001] This invention relates to the field of cleaning technology, and in particular to a method for removing rust from templates. Background Technology

[0002] Steel formwork, as an important construction material in modern building engineering, is widely used in bridges, high-rise buildings, water conservancy facilities, and other engineering fields due to its advantages such as high strength, high turnover rate, and good forming effect. However, during long-term use and storage, steel formwork is highly susceptible to corrosion due to environmental factors such as humidity, temperature, and acidic or alkaline media. Corrosion not only affects the appearance quality of the formwork but also reduces its mechanical properties and service life, leading to quality defects such as pitting and honeycombing on the surface of concrete components, seriously affecting the quality of the project.

[0003] For rust removal and cleaning of large caisson steel formwork surfaces, traditional rust removal methods are commonly used, involving manual labor and simple handheld tools, or experimental treatments are conducted using non-specialized general-purpose engineering machinery attachments. These existing technologies have the following main drawbacks in practical applications:

[0004] 1. Low cleaning efficiency and poor work continuity make it difficult to adapt to the pace requirements of large-scale prefabrication production, becoming a bottleneck restricting the overall efficiency improvement of the caisson production line; 2. The cleaning quality is unstable and uniformity is difficult to guarantee. In particular, the treatment effect is not good for large flat areas of the formwork panel and complex parts such as stiffening ribs and corners. Rust spots and attachments are easily left behind, which affects the appearance quality of the subsequent concrete. 3. The work is highly dependent on manual labor, involves high intensity, and mostly involves manual work at height, posing significant safety risks. The working environment also poses a threat to workers' health. 4. Existing tools are poorly compatible with large hoisting or construction machinery, have non-standardized interfaces, are cumbersome to assemble and disassemble, cannot achieve rapid docking and efficient power transmission, and have low equipment utilization. 5. Severe process wear and tear: Traditional grinding tools are prone to causing excessive wear or localized damage to the template panel, shortening the template's service life. At the same time, the tools themselves wear out quickly, resulting in high overall maintenance costs. Summary of the Invention

[0005] The purpose of this invention is to address the problems of existing technologies in rust removal and cleaning operations on the surface of large steel formwork, such as high labor intensity, low cleaning efficiency, poor work continuity, unstable cleaning quality, poor compatibility between general engineering machinery and cleaning tools, inability to achieve rapid docking and efficient power transmission, and low equipment utilization. This invention provides a method for rust removal from formwork.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A method for removing rust from templates includes the following steps: S1. Construction preparation; Construction preparation includes site survey, technical preparation and rust removal equipment preparation; Rust removal equipment includes rust removal devices and engineering machinery. Rust removal devices include quick couplings, rotating parts, brackets, cleaning rollers, rotating parts and cable connectors. Engineering machinery includes robotic arms. The end of the robotic arm is equipped with a quick-change mechanism, which is used to connect quick couplings. S2. Rust removal equipment connection and debugging; operate the robotic arm to accurately align and connect the quick-change mechanism and quick connector, and confirm that the locking pin of the quick-change mechanism is in place; connect the cable connector to the power distribution box, start the rust removal device, and let the rotating parts drive the cleaning drum in an unloaded state to confirm that the cleaning drum speed reaches the rated speed and there is no abnormal vibration; test the slewing function of the construction machinery and the smooth slewing of the rust removal device's rotating parts. S3. Surface pretreatment and trial cleaning: Perform preliminary blowing on the area of ​​the template to be cleaned, select a spot on the template for trial cleaning, operate the robotic arm to gradually bring the cleaning roller, which has been started and is rotating at low speed, closer to and in contact with the template surface, and maintain constant pressure to conduct a short-distance, slow cleaning test; determine the combination of process parameters suitable for the current rust condition of the template based on the immediate effect of the trial cleaning area. The process parameters include the constant pressure value, the travel speed of the rust removal device along the template surface, and the overlap width between adjacent cleaning strips; S4. Mechanized rotary grinding rust removal operation; Based on the process parameter combination calibrated by the trial cleaning, a systematic mechanized rotary grinding rust removal operation is carried out. For large-area flat template panels, the robotic arm is controlled to make the axis of the cleaning roller parallel to the template surface. The rust removal device is smoothly advanced at a uniform and continuous speed along the pre-planned longitudinal or transverse path, ensuring that each cleaning trajectory overlaps with the previous one to achieve full coverage cleaning. The cutting angle and posture of the cleaning roller are adjusted in real time by adjusting the robotic arm and rotating the rotating parts, so that the side or end of the cleaning roller can effectively conform to the irregular contour of the template for cleaning. Fixed-point grinding or small-amplitude reciprocating motion is used to clean the irregular contour area. S5. Cleaning quality inspection; the initial inspection is done by visual inspection, and the metal substrate of the template is fully exposed; a standard roughness comparison template is used to compare the cleaned surface, or a magnetic coating thickness gauge is used to detect the thickness of the residual non-metallic coating.

[0007] The template rust removal method described in this invention utilizes quick-connect couplings to allow the rust removal device to be quickly connected or disconnected from the robotic arm of construction machinery, expanding the applicability and utilization rate of the machinery. A support frame serves as the carrier for the rotating components and cleaning rollers. The mechanized rotary grinding operation, driven by the rotating components, is suitable for rust removal of large-area templates, significantly reducing manpower input and lowering high labor costs and related safety management costs. The rotating components enable the cleaning rollers to rotate and move, cutting into hard-to-reach areas for cleaning. Cable connectors allow for quick and stable connection to an external power distribution box. The mechanized rotary grinding process parameters are controllable, providing uniform and stable cutting and grinding action, completely eliminating problems such as uneven cleaning, missed areas, and excessive damage to the template substrate that are common in traditional processes. The surface cleanliness of the treated templates can consistently reach Sa2.5 or higher, providing excellent interface conditions for subsequent concrete pouring and effectively ensuring the appearance quality and long-term durability of precast components.

[0008] As a preferred technical solution of the present invention, in step S1, the on-site survey includes confirming the location, spatial layout, severity of rust and attachments of the template to be cleaned, and assessing the height of the on-site work surface, lighting conditions and whether there are any obstacles. Technical preparations include ensuring that the work area is equipped with a power supply with a capacity that meets the peak power requirements of the rotating and slewing components, and planning temporary cable laying routes.

[0009] As a preferred technical solution of the present invention, in step S2, the locking pin is confirmed to be in place by visually confirming that it is in place or by observing the status of the indicator light.

[0010] As a further preferred technical solution of the present invention, the circuit where the indicator light is located is connected to a limit switch or a proximity switch, and the locking pin is used to trigger the limit switch or the proximity switch.

[0011] As a preferred technical solution of the present invention, in step S3, a dry compressed air gun or a soft bristle cleaning tool is used to perform preliminary blowing on the area of ​​the template to be cleaned.

[0012] As a preferred technical solution of the present invention, in step S3, the overlap width between adjacent cleaning strips is 1 / 3 of the width of the cleaning roller.

[0013] As a preferred technical solution of the present invention, in step S4, the operating sound and temperature rise of the rotating parts are monitored, the uniformity of the rust removal effect is observed, and the wear of the brush bristles or abrasive of the cleaning roller is observed.

[0014] As a preferred technical solution of the present invention, in step S5, all areas found to be incompletely cleaned, with color differences or residual spots are clearly marked with easily erasable marks.

[0015] As a preferred embodiment of the present invention, the method for removing rust from the template further includes: S6. Disassembly and transfer of rust removal equipment: Turn off the control switch of rotating parts, and after the cleaning roller has completely stopped rotating, disconnect the cable of the rust removal device from the power supply. Operate the quick-change mechanism to release the mechanical lock between the quick-change mechanism and the quick connector, and place the rust removal device stably on the storage rack or transfer flatbed.

[0016] As a further preferred technical solution of the present invention, an air gun is used to clean the dust and debris adhering to the cleaning roller, the support and the rotating parts.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: This invention discloses a method for rust removal from formwork. By incorporating quick-connect couplings, the rust removal device can be rapidly connected or disconnected from the robotic arm of construction machinery, expanding the applicability and utilization rate of the machinery.

[0020] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0021] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of the present invention is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is typically placed during use.

Therefore, they should not be construed as limitations on the present invention.

[0022] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but that it can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0023] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0024] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, nine, or even more than nine.

[0025] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0026] In related technologies, rust removal and cleaning of large steel formwork surfaces is characterized by high manual labor intensity, low cleaning efficiency, poor work continuity, and unstable cleaning quality. Furthermore, the compatibility between general engineering machinery and cleaning tools is poor, hindering rapid docking and efficient power transmission, resulting in low equipment utilization. Therefore, the technical solution of this application was developed. The following section combines... Figures 1 to 3 To elaborate.

[0027] Example 1 like Figures 1 to 3 As shown, the method for removing rust from templates according to the present invention includes the following steps: Step 1: Construction Preparation During the construction preparation phase, a comprehensive site survey and technical briefing are required. The technical briefing includes technical preparation and rust removal equipment preparation. The rust removal equipment includes rust removal device 1, which includes quick connector 11, rotating part 12, bracket 13, cleaning roller 14, rotating part 15, special waterproof cable connector, control system and switching power supply.

[0028] The quick connector 11 is equipped with an angle sensor and a limit switch or proximity switch. The angle sensor detects the tilt angle of the component used for template cleaning relative to the horizontal plane, and the limit switch or proximity switch detects whether the locking pin of the robotic arm connected to the quick connector 11 is in place. A rotating component 12 is connected to the quick connector 11 and is equipped with an encoder to detect the rotation angle of the rotating component 12. A bracket 13 is connected to the rotating component 12, and the rotating component 12 can drive the bracket 13 to rotate relative to the quick connector 11. A cleaning roller 14 is rotatably connected to the bracket 13 via a bearing. The cleaning roller 14 is used for template cleaning and is equipped with a pressure sensor. A vibration sensor is located at the bearing. The pressure sensor detects the pressure between the cleaning roller 14 and the template surface, and the vibration sensor detects the vibration spectrum and amplitude of the bearing. The moving part 15 is connected to the bracket 13. The rotating part 15 is connected to and drives the cleaning roller 14 to rotate. A speed sensor and a temperature sensor are connected to the rotating part 15. The speed sensor is used to detect the speed of the cleaning roller 14, and the temperature sensor is used to detect the temperature change of the rotating part 15. The cable connector is used to connect an external power supply and is electrically connected to the rotating part 12 and the rotating part 15. The control system is located on the bracket 13 and is electrically connected to the tilt sensor, limit switch or proximity switch, encoder, pressure sensor, vibration sensor, speed sensor, rotating part 12, and rotating part 15. The switching power supply is located on the bracket 13. The input of the switching power supply is electrically connected to the cable connector, and the output of the switching power supply is electrically connected to the tilt sensor, limit switch or proximity switch, encoder, pressure sensor, vibration sensor, speed sensor, and control system.

[0029] The on-site survey included confirming the specific location, spatial layout, and severity of rust and attachments of the large caisson template to be cleaned, as well as assessing the height of the work surface, lighting conditions, and the presence of any obstacles.

[0030] Technical preparations need to be verified and ensure that the work area is equipped with a stable and reliable 380V industrial three-phase power supply. The power supply capacity must meet the peak power requirements of the rotating part 12 and the rotating part 15 of the rust removal device 1, and a temporary laying path for the dedicated cable should be planned. The rotating part 15 is an electric motor connected to a reducer.

[0031] The preparation of the rust removal equipment requires the use of a working machine 2 with a suitable tonnage as the main unit. That is, the rust removal equipment also includes the working machine 2, which is an excavator. The hydraulic quick-change mechanism of the working machine 2 should be checked in advance to ensure that it is in good working order and without leakage.

[0032] Step 2: Connecting and Debugging Rust Removal Equipment Connecting and debugging the rust removal equipment is a crucial step in ensuring the normal operation of the rust removal device 1. First, drive the construction machinery 2 smoothly to the pre-planned work position and ensure that it is parked on a solid and level ground. If necessary, lower the safety support to enhance stability.

[0033] The operator precisely manipulates the robotic arm 21 of the construction machinery 2, ensuring that the quick-change mechanism at the end of the robotic arm 21 is accurately aligned with the quick connector 11 of the rust removal device 1. This activates the quick-change function, enabling the construction machinery 2 to mechanically grasp and rigidly lock the rust removal device 1. The operator visually confirms that the locking pin of the quick-change mechanism is in place or observes the indicator light status to confirm that the locking pin is in place, ensuring an absolutely reliable connection. The indicator light provides feedback through a limit switch or proximity switch on the quick connector 11. The locking pin's placement triggers the limit switch or proximity switch, activating the indicator light circuit and illuminating the light, thus confirming a stable connection between the construction machinery 2 and the rust removal device 1. The limit switch is a contact position sensor, while the proximity switch is a non-contact position sensor. Both types of position sensors can determine whether the locking pin is correctly inserted into the corresponding lock hole of the quick connector 1 and in place using methods such as contact rod type, infrared, inductive, capacitive, photoelectric, and Hall effect.

[0034] Subsequently, the cable connector provided with the rust removal device 1 is reliably connected to the distribution box prepared on site. The cable connector is a gland or an industrial plug.

[0035] After the preparation work is completed, start the control system of the rust removal device 1, so that the rotating part 15 drives the cleaning drum 14 to run under no-load conditions; use the speed sensor to detect that the speed of the cleaning drum 14 reaches the design requirement of 2000 Rpm, and use the vibration sensor to detect the vibration spectrum and amplitude of the bearing to confirm that there is no abnormal vibration; or the operator needs to observe and listen from a safe distance to see if the rust removal equipment is running smoothly and whether there is any abnormal vibration or noise, and use a speed measuring instrument to confirm that the speed of the cleaning drum 14 reaches the design requirement of 2000 Rpm.

[0036] At the same time, the rotation function of the construction machinery 2 was slowly operated to test whether the rust removal device 1 could rotate smoothly at a speed of about 13 Rpm, verifying that there was no interference or jamming in each degree of freedom of motion; and the rotation component 12 was slowly operated to test the smooth rotation of the cleaning roller 14 driven by the bracket 13.

[0037] Step 3: Surface pretreatment and trial cleaning Before large-scale rust removal, surface pretreatment and parameter calibration must be performed. First, use a high-powered dry compressed air gun or a soft-bristled cleaning tool to preliminarily blow away surface dust, loose sand particles, and flaked rust flakes to prevent these impurities from affecting the subsequent rotary grinding effect and the lifespan of the rust removal equipment.

[0038] Subsequently, a representative area on the template that does not affect the overall quality (usually located in a corner or inconspicuous position) is selected for a trial cleaning operation. The robotic arm 21 of the engineering machinery 2 is slowly operated so that the cleaning roller 14, which has been started and is rotating at a low speed, gradually approaches and slightly contacts the template surface, maintaining constant pressure to conduct a short-distance, slow cleaning test.

[0039] By observing the immediate effects of the trial cleaning area, the operator can intuitively judge and preliminarily determine the optimal combination of process parameters suitable for the current rust condition of the template. This mainly includes the constant pressure value of the rust removal device 1 on the template surface (the pressure is adjusted by controlling the precision of the pilot valve of the engineering machinery 2, and the real-time pressure can be fed back by the pressure sensor), the optimal travel speed of the rust removal device 1 along the template surface, and the reasonable overlap width between adjacent cleaning strips (usually recommended to be 1 / 3 of the width of the cleaning roller 14), providing a basis for subsequent efficient and uniform comprehensive operations.

[0040] Step 4: Mechanized rotary grinding for rust removal Based on the optimal parameters calibrated during the trial cleaning phase (constant pressure value, travel speed, and overlap width between cleaning strips), a systematic mechanized rotary grinding rust removal operation is carried out. For large, flat template panels, the operator manipulates the robotic arm 21 of the engineering machinery 2 to make the axis of the cleaning roller 14 of the rust removal device 1 parallel to the template surface, and smoothly advances the rust removal device 1 at a uniform and continuous speed along a pre-planned longitudinal or transverse path, ensuring that each cleaning trajectory has appropriate overlap with the previous one, achieving seamless and comprehensive coverage cleaning.

[0041] When encountering complex structural parts such as vertical stiffening ribs, inside and outside corners, and around bolt holes on the template surface, it is necessary to make full use of the multi-joint flexibility of the mechanical arm 21 of the engineering machinery 2 and the rotation function of the rust removal device 1 itself, and adjust the cutting angle and posture of the cleaning roller 14 in real time so that the side or end of the cleaning roller 14 can effectively fit the irregular contour for fine cleaning. "Spot grinding" (fixed-point grinding) or small-amplitude reciprocating motion can be used to ensure that the cleaning of complex areas meets the standards.

[0042] Throughout the operation, the operator must continuously monitor the operating sound and temperature rise of the rotating part 15 (obtained through a temperature sensor), observe the uniformity of the rust removal effect, and pay attention to the wear of the bristles or abrasive on the cleaning roller 14. If necessary, the operation should be paused to clean up the debris accumulated on the cleaning roller 14, ensuring that the rust removal device 1 is always in a highly efficient and stable working state.

[0043] Step 5: Cleaning and Quality Inspection After each logical work unit is completed (such as a complete template or an area that can be inspected independently), the machine must be stopped immediately for a system cleaning quality inspection. The initial inspection is conducted visually, and the standard requires that the metal substrate of the template be fully exposed, with no visible rust spots, scale, cement residue or oil stains on the surface, and the overall appearance should show a uniform metallic color or a consistent pre-treatment level.

[0044] For projects with strict process requirements, a standard roughness comparison template (such as Sa2, Sa2.5 or St3 grade template) should be used to compare the cleaned surface closely, or a magnetic coating thickness gauge should be used to detect the thickness of the residual non-metallic coating in order to quantitatively assess whether the cleanliness meets the interface requirements for subsequent anti-corrosion coating or concrete pouring.

[0045] Inspectors clearly marked all areas found to be incompletely cleaned, with color differences, or with residue using an easily erasable marker. Subsequently, the operator must, based on the marked locations, re-operate the construction machinery 2 to drive the rust removal device 1 to perform precise and targeted cleaning of these specific areas until the area passes a re-inspection, ensuring the overall work surface meets quality standards.

[0046] Step Six: Disassembly and Relocation of Rust Removal Equipment After all cleaning quality has been inspected and approved, the disassembly and transfer of the rust removal equipment will begin. First, remove the rust removal device 1 from the template surface and place it above a safe open area. The operating sequence must be strictly followed: first, turn off the control switch of the rotating part 15 on the rust removal device 1; after the cleaning roller 14 has completely stopped rotating, disconnect the cable of the rust removal device 1 from the on-site power distribution box. After power is cut off, operate the quick-change mechanism of the engineering machinery 2 to release the mechanical lock between the quick-change mechanism and the quick connector 11, and place the rust removal device 1 stably on a dedicated storage rack or transfer flatbed cart.

[0047] Subsequently, basic post-operation maintenance was performed on the rust removal device 1, including using an air gun to clean the metal dust and debris adhering to the cleaning roller 14, the outer casing and baffle 131 of the support 13, and the rotating parts 15; checking the cable sheath for damage; and confirming that all fasteners were secure. While the rust removal equipment was being moved, auxiliary personnel were assigned to clean the current work site, collect scattered rust and dust, and restore the site to cleanliness.

[0048] Finally, the safe and orderly transfer of construction machinery 2 and rust removal equipment 1 to the next planned work area marks the end of a complete standard operating cycle.

[0049] The rust removal method for templates described in this embodiment utilizes a quick-connect coupling to allow the rust removal device 1 to be quickly connected to or disconnected from the robotic arm 21 of the construction machinery 2, expanding the applicability and utilization rate of the construction machinery 2. The bracket 13 serves as the carrier for the rotating component 15 and the cleaning roller 14. The mechanized rotary grinding operation driven by the rotating component 15 is suitable for rust removal of large-area templates, greatly reducing manpower input and lowering high labor costs and related safety management costs. The rotating component 12 enables the cleaning roller 14 to rotate and move, cutting into dead corners for cleaning. A cable connector allows for quick and stable connection to an external power distribution box. The mechanized rotary grinding process parameters are controllable, providing uniform and stable cutting and grinding action, completely eliminating problems such as uneven cleaning, missed treatment, and excessive damage to the template substrate that are easily caused by traditional processes. The surface cleanliness of the treated template can stably reach Sa2.5 or higher, providing excellent interface conditions for subsequent concrete pouring and effectively ensuring the appearance quality and long-term durability of precast components.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
