Technical Field

[0001] The invention relates to the technical field of template cleaning, and in particular to an intelligent cleaning and maintenance method suitable for prefabricated box beam templates. Background Art

[0002] Prefabricated bridge engineering is a modern bridge construction method, which mainly concentrates the box girders in the prefabrication yard for production. During the casting process of the prefabricated box girders, it needs to be completed in the box girder steel formwork, similar to plastic products in plastic molds.

[0003] After the box girder is demoulded, concrete residue or stagnation on the surface of the steel mold requires manual cleaning and application of mold release oil to complete the cleaning and maintenance process of the mold. However, the process consumes a lot of manpower and time, resulting in labor-intensive problems. At the same time, the dust generated by grinding and cleaning is prone to occupational health problems such as pneumoconiosis. Summary of the invention

If the quality inspection result is clean, a release agent is applied to the surface of the steel formwork. If the quality inspection result is unclean, the surface of the steel formwork is subjected to strong decontamination of the noise area with a steel brush, high-pressure vacuuming is performed again, and laser scanning quality inspection is performed again until the quality inspection result is clean.

[0007] Preferably, in the high-pressure vacuuming, a telescopic vacuuming mechanism is used to perform high-pressure vacuuming on the surface of the steel template.

[0008] Preferably, in the laser scanning quality inspection, a millimeter-level laser radar is used to detect anomalies in the echo of the steel template surface, which is used to determine the location of the unevenness on the steel template surface and feed back to the central control to arrange subsequent strong decontamination of the noise area with a steel brush.

[0009] Preferably, in the steel brush strong decontamination of the noise point area, a telescopic steel brush mechanism is used to strongly polish the noise point positions detected in the laser scanning quality inspection.

[0010] Preferably, during the high-power grinding, the rotation speed is controlled to be 150 r / min and the contact surface pressure is 50 par.

DETAILED DESCRIPTION

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments.

[0015] Embodiment: An intelligent cleaning and maintenance method suitable for prefabricated box girder formwork, comprising PE polishing and high-pressure vacuuming on the surface of the steel formwork in sequence, and laser scanning quality inspection on the surface of the steel formwork after high-pressure vacuuming. If the quality inspection result is clean, a release agent is applied to the surface of the steel formwork. If the quality inspection result is unclean, the surface of the steel formwork is subjected to strong decontamination of the noise area with a steel brush, high-pressure vacuuming is performed again, and laser scanning quality inspection is performed again until the quality inspection result is clean.

[0016] Among them, in the PE grinding, a telescopic roller brush mechanism is used to clean and grind the surface of the steel template. The roller brush material of the roller brush mechanism is plastic brush wire, which can effectively clean the template surface and protect the template from additional damage.

[0017] In the high-pressure vacuuming, a telescopic vacuuming mechanism is used to perform high-pressure vacuuming on the surface of the steel template, and a strong negative wind pressure is formed by turbocharging. This is performed immediately after the PE grinding process to effectively remove the dust generated by the grinding.

[0018] In the laser scanning quality inspection, a millimeter-level laser radar is used to detect anomalies in the echo of the steel template surface, which is used to determine the location of the unevenness on the steel template surface and feedback to the central control to arrange subsequent strong decontamination of the noise area with a steel brush.

[0019] In the steel brush strong decontamination of the noise point area, a telescopic steel brush mechanism is used to strongly grind the noise point position detected in the laser scanning quality inspection. During the strong grinding, the rotation speed is controlled to 150r / min and the contact surface pressure is 50par. Excessive pressure will cause excessive wear on the surface of the steel mold.

[0020] In the process of applying the release agent, a telescopic oil spraying mechanism and a brush coating mechanism are used to apply the release agent to the surface of the steel template, and the oil spraying mechanism uses an oil spray gun to spray the entire surface.

[0021] When the intelligent cleaning and maintenance method is applied in practice, it can make use of a scaffolding structure composed of a variety of mechanical mechanisms, and install mechanical mechanisms such as cleaning, grinding, applying mold release agents, and dust removal required for cleaning the bottom mold and the side molds inside, and hang a noise-reducing insulating protective shed on the outside. The overall design concept is similar to that of an automatic car wash platform. Through the production and application of this embodiment, it can replace the manual grinding and oiling processes, reduce the occupational health hazards of workers' dust inhalation, and at the same time realize green and environmentally friendly construction operations, and improve the construction efficiency of template cleaning and maintenance.

[0022] In addition, the corresponding intelligent system is matched to complete one-button start. According to the process requirements of template cleaning, grinding, dust collection, and brushing of mold release oil, the control systems of the corresponding roller brush mechanism, steel brush mechanism, blowing and dust collection mechanism, oil spraying mechanism, and brush coating mechanism are developed one by one, so that the manipulators in each link can be switched freely, and the quality inspection system is equipped before oil spraying to ensure that the mold release oil is further applied after cleaning.

[0023] The lateral section of the prefabricated box girder template is curved. During the grinding process, there is a problem of difficulty in the bionic movements of the robot. Unlike human limbs that can grind single-point surfaces at multiple angles, the robot needs to increase the working area as much as possible while also being able to work with a high degree of fit and tightness to avoid invalid working areas and avoid abnormal wear and tear in the high point areas of the template curve due to grinding, thus achieving a grinding technology without dead ends.

[0024] The robot will inevitably generate a lot of dust and noise during the high-speed grinding and high-pressure blowing process. When designing the equipment, the equipment should be made as closed as possible to isolate it from the outside world. At the same time, multiple dust removal and suction devices are installed inside the factory shed, connected to the external dust collection and recovery bags. When the dust is full, the management personnel are reminded to dump it. The outside of the factory shed is wrapped with sound-absorbing and sound-insulating materials to reduce noise pollution in the factory and realize green construction technology.

[0025] The above are only implementation modes of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent schemes made using the contents of the present invention specification, directly or indirectly applied in other related technical fields, are also within the patent protection scope of the present invention.
