Abstract

The invention belongs to the technical field of covering sand platforms, and particularly relates to a covering sand table device for long jump. The covering sand table device comprises a covering drive device and a fixed device. After a sandpit is used, the covering sand table device is transferred to the edge of the sandpit; then the fixed device is fixed; one end of a thin film is fixed on thefixed device; the covering drive device is placed on the upper side of the sandpit; and then the covering drive device is manually pulled to extend the thin film in the covering drive device outwardsto cover the sandpit, so that the influence on the use by athletes due to the fact that rainwater falls into the sandpit to cause caking and hardening of sand in the rainy weather during the non-usingprocess is prevented. During use, the covering drive device is pulled manually to retract the thin film in the covering drive device inwards to expose the sandpit.
