Description

Technical Field

[0001] The utility model relates to the technical field of coordinate collection, in particular to a driving coordinate collection device for a mine sand pit. Background Art

[0002] Mine sand pits are primarily used to store sand to be transported. Mining trucks transport the sand to the edge of the pit and unload it into the pit. The sand in the pit is unevenly distributed, with a low center and high sides. Locally, there are many sand piles. When the sand on either side rises above the pit, unloading becomes impossible. Therefore, to improve the space utilization of the pit and ensure normal unloading, the sand at the edge of the pit or in excessively high areas within the pit needs to be moved to lower areas within the pit. This requires leveling the sand within the pit. To perform this leveling, the actual amount of sand in each area of the pit needs to be known to facilitate leveling. Therefore, coordinate collection of the pit is necessary.

[0003] A Chinese patent (authorization announcement number: CN221325390U, authorization announcement date: 2024-07-12) proposes a driving coordinate acquisition device for a mine sand pit, including an X-axis acquisition module and a Y-axis and Z-axis combined acquisition module; the walking component includes a shell, a wheel set that is rotatably arranged inside the shell and rolls on a guide rail, and an encoder set on the wheel set.

[0004] In response to this disclosed technology, existing vehicle-mounted coordinate acquisition devices for mine sand pits use an X-axis acquisition module to collect X-axis information, and a Y-axis and Z-axis combined acquisition module to collect Y-axis and Z-axis information. This information forms three-dimensional coordinates, enabling the construction of a three-dimensional spatial model of the sand pit's interior. However, when collecting Z-axis information, multiple equally spaced laser rangefinders are installed. When these laser rangefinders are operating, their emitted laser beams may interfere with each other, thereby affecting the accuracy of data measurement. Simultaneously installing multiple laser rangefinders requires complex wiring and mounting, which also increases installation difficulty. Therefore, we propose a vehicle-mounted coordinate acquisition device for mine sand pits. Utility Model Content
