This invention discloses a disturbance-resistant trajectory tracking and anti-sway control method for a dual-axle crane. It constructs a dynamic model of the variable-rope-length dual-axle crane under unknown external disturbances. By separating the drivable and non-drivable states, the dynamic model is represented as a cascaded system. The trajectory error vector is obtained by subtracting the actual coordinates of the load's center of mass from its desired trajectory vector. The load position error is then integralized from the trajectory error vector, and an LSNF function is constructed. Position control parameter matrices and velocity control parameter matrices are defined, leading to a pseudo-controller and a velocity error vector. Finally, the actual controller is constructed based on the velocity control parameter matrix, velocity error vector, trajectory error vector, pseudo-controller, and the cascaded system dynamic model. Using this technical solution, load positioning is more accurate, and the cable's anti-interference capability is stronger.

This invention relates to the field of crane equipment, specifically disclosing a crane with online wire rope detection function, comprising: a gantry, an electric hoist, a reel, a hook, and a wire rope. A guide plate and a drive unit are installed on the outside of the electric hoist. The guide plate and drive unit enable the wire rope to be wound onto the reel and exit according to the corresponding position of the guide plate. An online detector is installed at the exit end of the wire rope through a structure such as a swing arm, sleeve, and slide bar, and is installed close to the lower part of the guide plate. This allows the online detector to detect the working condition of the wire rope in real time, quickly diagnose defects in the rope, and promptly take corrective measures to ensure safe production.

This invention discloses a fault diagnosis method for crane maintenance management, relating to the field of crane equipment operation and maintenance technology. It includes collecting a multi-source sensor data sequence consisting of vibration spectrum of the hoisting mechanism, wire rope tension fluctuations, and temperature changes at hinge points within the crane's operating cycle. The multi-source sensor data sequence is time-synchronized and outlier-removed to generate a standardized synchronization data matrix. The synchronization data matrix is ​​then fed into a hierarchical fault feature extraction process, outputting degradation feature vectors for key components and anomaly pattern identifiers. The remaining effective working range length of the components is calculated using the degradation feature vectors, and the fault initiation time point is located using the anomaly pattern identifier. These two types of information are merged and encoded to generate a maintenance trigger signal, which is then pushed to the crane control terminal display interface. This method achieves standardized organization and hierarchical feature mining of multi-source operating data, quantifies the service status of components, and identifies the fault initiation time, providing a standardized status basis for crane maintenance management.

This utility model relates to the field of truss crane maintenance technology, specifically to a static inspection device for truss crane equipment. It includes an ultrasonic flaw detector and a probe assembly. In this utility model, after aligning the nozzle with the weld area, pressing the trigger along the extension rod axis moves the second rack towards the limit switch, simultaneously driving the movable frame to move the nozzle and cleaning assembly towards the distal end of the probe body's detection end. When the second rack contacts and triggers the limit switch, the feed pump delivers coupling agent to the nozzle, precisely spraying the coupling agent onto the weld. Simultaneously, a servo motor drives the rotating plate and sponge cloth to rotate, wiping the probe's detection end surface, effectively removing residual coupling agent from the probe's detection end surface during the inspection process. This achieves synchronized coupling agent spraying and probe cleaning, reducing the safety risks and implementation difficulties associated with alternating multi-process operations in high-altitude environments.

The proposed solution involves a cylindrical sleeve, hollow inside, with only one side missing in a U-shape (the opposite side is not missing). The part of the body that contacts the U-shape is rectangular. Inside the sleeve is a gradually protruding triangular locking pin. Combined with a shaft that has a concave section near the end, when assembled, the U-shaped design creates a slight elastic force, allowing the shaft to pass through the locking pin, and then the apex of the triangle fits into the concave section, forming a "pin-groove" mechanical lock. As a result, the shaft is held securely in place while still rotating freely, without the need for screws or tightening tools. This solution reduces materials, labor, and electricity consumption, increases assembly productivity, and is applicable to electric fans, rotating lights, rotating brackets, and rotating positioning crane equipment.

This utility model relates to the field of crane equipment technology and discloses a crane beam structure, including a beam body, which is a hollow rectangular steel structure. This crane beam structure achieves a balance between strength and precise weight reduction through the design of I-shaped reinforcing ribs and weight-reducing holes. The I-shaped reinforcing ribs are made of high-strength alloy steel, and their horizontal flanges can efficiently bear the vertical load during lifting operations and evenly distribute the stress to the inner wall of the beam body. The vertical webs can resist lateral shear forces, strengthening the beam rigidity from the core load-bearing layer. The weight-reducing holes are only opened in the "non-reinforcing rib projection area" on the upper and lower surfaces of the beam, avoiding the load-bearing area of ​​the reinforcing ribs and reducing redundant material through precise hole opening. With the synergy of these two aspects, the beam will not suffer from insufficient local strength due to weight reduction, nor will it cause weight redundancy due to excessive reinforcement, perfectly meeting the dual requirements of high-strength load-bearing and low-energy-consumption operation of cranes.
