The invention discloses a ground anchor device of a crane. The ground anchor device comprises a ground anchor pit, a ground anchor bracket, a ground anchor pin, a winding drum mechanism and a locking mechanism, the ground anchor support, the winding drum mechanism and the locking mechanism are installed on a crane walking cross beam, the ground anchor support is located over the ground anchor pit, and the ground anchor pin is used for penetrating through the ground anchor support to be inserted into the ground anchor pit. The winding drum mechanism is connected with the ground anchor pin through a rope, and the winding drum mechanism rotates clockwise or anticlockwise to lift or drop the ground anchor pin; the locking mechanism is used for locking the winding drum mechanism. The crane ground anchor device is reasonable in structural design and convenient and labor-saving to operate. The ground anchor pin can be easily lifted out of the ground anchor pit by rotating the handle clockwise, the ground anchor pin can easily fall into the ground anchor pit by rotating the handle clockwise, and the risks of labor waste, inconvenience and mechanical injury caused by improper operation when a worker directly lifts the ground anchor pin by hand in a traditional mode are avoided.

    本发明公开了一种起重机地锚装置,包括:地锚坑、地锚支架、地锚销、卷筒机构、锁定机构;地锚支架、卷筒机构、锁定机构安装在起重机行走横梁上,地锚支架位于地锚坑正上方,地锚销用于穿过地锚支架插入地锚坑中;卷筒机构与地锚销通过绳索连接,卷筒机构顺时针或逆时针转动可提起或落下地锚销;锁定机构用于锁定卷筒机构。本专利所述起重机地锚装置结构设计合理、操作方便省力。通过顺时针转动手柄可轻松将地锚销提出地锚坑,顺时针转动手柄可轻松将地锚销落入地锚坑,避免了人员采用传统方式直接用手提落地锚销的费力不便以及操作不当带来机械伤害的风险。
