可自动闭锁的跟斗滑车
摘要：
本发明涉及工程机械领域，公开了可自动闭锁的跟斗滑车，包括挂钩、挂环和定滑轮，挂环和定滑轮分别设置于挂钩的两侧，挂钩包括开口；挂钩还包括第一支臂和第二支臂，第一支臂和第二支臂向外张开以形成开口；所述可自动闭锁的跟斗滑车还包括锁舌和联动装置；锁舌设置于挂钩的开口处，锁舌包括锁止端和控制端，锁止端用于与第二支臂相抵触以封闭开口，第一支臂设有供控制端穿过的过孔，锁舌通过控制端与第一支臂活动连接，以使锁舌的控制端带动锁止端打开或封闭开口；联动装置设置于挂钩，联动装置包括设置于锁舌控制端的第一绳索栓系孔以及设置于第二支臂自由端的第二绳索栓系孔。
摘要（英）：

The invention relates to the field of engineering machinery, and discloses a flipping tackle capable of automatically locking. The flipping tackle comprises a hook, a hanging ring, a fixed pulley, a lock tongue and a linkage device. The hanging ring and the fixed pulley are arranged on the two sides of the hook respectively. The hook comprises an opening. The lock tongue is arranged in the opening of the hook. The linkage device is arranged on the hook, connected with the lock tongue and used for controlling the lock tongue to open or close the opening after being stressed. Due to the fact that the linkage device is arranged and can control the lock tongue to open or close the opening after being stressed, the flipping tackle has the self-locking function, and the safety coefficients of the flipping tackle when the flipping tackle is used are improved.
