Description

Technical Field

[0001] This invention relates to the field of intelligent detection technology, and in particular to a digital intelligent crane guide rail smoothness detection system. Background Technology

[0002] The digital intelligent crane guide rail smoothness detection system is a crane safety testing device that monitors the operating status of crane guide rails under service conditions in real time, accurately quantifies the deformation of smoothness parameters such as straightness, parallelism, and height difference, and compares it with the allowable limits stipulated by national or industry regulations to determine whether the guide rails meet the requirements for safe use. By simulating or monitoring the operating status of crane guide rails under service conditions, it quantifies the deformation of their smoothness parameters and determines whether they exceed the allowable deformation limits, providing data support for the safe operation of cranes.

[0003] Existing methods for testing the smoothness of crane guideways mostly rely on individual testing tools or equipment that can only measure a single smoothness parameter. Cranes operate in complex environments, and guideways must simultaneously meet multiple smoothness requirements, including straightness, parallelism, and height difference. This necessitates the use of multiple testing devices to perform tests in different directions and with different parameters. This not only results in high equipment procurement and maintenance costs but also requires frequent manual tool switching and adjustments to testing stations, leading to low efficiency. Furthermore, some testing equipment lacks adaptability, failing to flexibly adjust testing parameters based on the guideway gauge and material of different crane types. It also lacks dynamic tracking and 3D coordinate modeling capabilities, making it difficult to visually present the evolution trend of guideway smoothness over time. This hinders the provision of continuous data support for long-term safe operation and maintenance of cranes, and creates inconvenience for preventative maintenance and lifespan assessment of guideways. Therefore, we propose a digital intelligent crane guideway smoothness testing system. Summary of the Invention

An optical cleaning component, including a miniature air pump and cleaning brushes, is located inside the module near the optical measurement unit. This component periodically blows air to remove dust and gently brushes the optical lens, preventing dust accumulation from affecting measurement accuracy. The module also includes a temperature and humidity compensation module that monitors the internal temperature and humidity in real time and uses algorithms to compensate for changes in temperature and humidity, ensuring that the coordinate measurement error is stably controlled within ±0.5mm.

[0012] Preferably, the anti-slip control component of the intelligent inspection vehicle is linked to the walking system. The walking system of the intelligent inspection vehicle is driven by a servo motor, and the total mass of the intelligent inspection vehicle is ≤15Kg.

The speed sensors can collect the vehicle's driving speed data in real time and feed it back to the control core unit, thereby achieving precise control of the driving speed. The inner side of the walking wheel sets is equipped with track limit wheels. The track limit wheels are perpendicular to the walking wheel sets. The track limit wheels can roll against the side of the guide rail, effectively preventing the intelligent inspection vehicle from deviating laterally when traveling along the track, ensuring that the straight-line deviation is ≤±1mm / m.

[0014] Preferably, the standard adaptation module of the system control and data analysis software pre-stores national standards, industry standards, and various crane manufacturer standards. The standard adaptation module is electrically connected to the operation buttons, and the corresponding standard can be selected through the operation buttons. The standard adaptation module of the system control and data analysis software can also automatically compare the test data with the selected standard to quickly determine whether parameters such as guide rail straightness and parallelism are qualified. The operation buttons and the system control and data analysis software work together to support custom parameter input, and the crane rail specifications, test sampling interval, travel speed of intelligent test trolley, and measurement accuracy level of high-precision track coordinate detection module can be manually entered.

[0015] The data visualization module is used to convert the detected guide rail coordinate data into a three-dimensional trajectory graph and parameter curve, and to present the detection results intuitively through color annotation. It is also used to view the detection data in real time and to trace back historical data.

The lithium battery pack supports continuous operation for 8 hours on a single charge. The power monitoring module is used to monitor the power of the lithium battery pack in real time. When the power of the lithium battery pack is lower than 20%, the power warning module issues a warning and controls the power indicator light to light up through the control core unit. At the same time, the power warning module also sends a low power warning signal to the system control and data analysis software to remind users to charge in time.

[0018] Preferably, a data storage module is installed inside the intelligent detection vehicle near the control core unit. The data storage module is connected to the system control and data analysis software, which is also connected to a cloud server. The data storage module can perform local storage and backup of the detection data, and also supports cloud-based synchronous storage on the cloud server.

[0022] This invention integrates a high-precision optical measurement module and an automatic target tracking module into a high-precision track coordinate detection module. The high-precision track coordinate detection module works in conjunction with the target rotation and walking systems of the intelligent inspection trolley.
