Embodiment Construction

[0023] Such as figure 1 As shown, the laser scanner (2), the container position management display (3), the siren (4), the crane PLC (5), and the display screen (6) are all connected to the computer (1). Siren (4) can warn tire crane driver by sound or combination of sound and light or other methods.

[0024] Such as figure 2 As shown, during the travel of the tire crane (9), two laser scanners (2) simultaneously scan and measure the side of the container (8) on the container yard and the gap between the container (8) and the container (8), so as to The container (8) positions and gaps stacked on the yard are used as reference. If the tire crane (9) deviates from the driving lane, the distance from the side of the container (8) on the container yard measured by the laser scanner (2) to the laser scanner (2) will become larger or smaller, and the computer (1) analyzes the data , it is possible to predict the deviation distance of the tire crane (9) if the deviation is not c...

Abstract

According to the invention, laser scanners are arranged at the center of lower side surfaces between two columns at two sides of a rubber-tyred gantry crane and are slightly higher than a container truck trailer panel and lower than height of a container and are used for detecting gaps between containers' side surface and containers on a container yard. Thus, rubber-tyred gantry crane walking positioning, position location of containers on the container yard, automatic correction, anti-collision warning and container truck alignment anti-lifting are realized. The equipment comprises the laser scanners, containers, a computer, an alarm, a container position management display, display screens, a rainproof cover and a crane PLC. The laser scanners are respectively mounted at the center of lower side surfaces between the two columns at two sides of the rubber-tyred gantry crane, and are slight higher than the container truck trailer panel and lower than height of a container. The gaps between containers' side surface and containers on the container yard are used as reference. The computer is installed in an electrical room. The alarm is mounted inside a cab of the rubber-tyred gantry crane. The display screens are installed at two sides of the rubber-tyred gantry crane and positioned at the same eye level of a driver in the container truck cab.

Description

technical field [0001] The invention relates to container hoisting in container loading and unloading operations, tire crane positioning, walking deviation correction, container truck alignment and lifting prevention, and is especially suitable for tire crane lifting container loading and unloading operations. Background technique [0002] At present, the detection methods for the deviation correction and collision avoidance of container tire cranes in the site include GPS positioning automatic deviation correction method, single-point laser range finder combined with reflective plate automatic deviation correction method, image processing deviation correction, and manual deviation correction, but these methods have their own shortcomings. CPS positioning is vulnerable to artificial data tampering, which leads to data errors and needs to be corrected regularly. The single-point laser rangefinder combined with the automatic deviation correction method of the reflector needs t...
