The invention discloses an air automatic safety latch hook device and a latch hook method. The air automatic safety latch hook device comprises a cylinder body, a cover plate, a pressing rod, a fixingring and a fixing base, the side surface of one end of the cylinder body is provided with a high-pressure air pipe connector connected with an air pipe, the pressing rod is arranged in the cylinder body in a drawable mode, and the end, located in the cylinder body, of the pressing rod is fixedly connected with a sealing sliding plug; the fixing ring is arranged on the periphery of the cylinder body in a sleeving mode and is in threaded connection with the cylinder body; the fixing base sleeves the periphery of the cylinder body and is in threaded connection with the cylinder body; and the bottom end of the fixing base is fixedly connected with a coupler, and the top end abuts against the bottom end of the fixing ring. According to the air automatic safety latch hook device and the latch hook method, after air is introduced into the high-pressure air pipe connector, the pressing rod slides downwards under the pressure of the air, the fixing base is arranged on the periphery of the cylinder body in a sleeving mode, the bottom end is fixedly connected with the coupler into a whole, and the top end abuts against the bottom end of the fixing ring; and the pressure rod slides downwardsthrough air pressure so that a bearing plate can tightly press a coupler knuckle lock, wrong unlocking of the coupler due to human factors can be effectively prevented, and unhooking is prevented.

    本发明公开了一种空气自动安全锁钩器及锁钩方法,包括缸体、盖板、压杆、固定环和固定座,缸体一端的侧面具有与风管连接的高压风管接口,压杆可抽拉地设于缸体的内部,压杆位于缸体内部的端部固定连接有密封滑塞;固定环套设于缸体的外周,且与缸体螺纹连接;固定座套设于缸体的外周且与其螺纹连接;固定座的底端与车钩固定连接,顶端与固定环的底端抵接。本发明公开的空气自动安全锁钩器及锁钩方法,当高压风管接口接入空气后,压杆在空气的压力下向下滑动,固定座套设于缸体的外周,底端与车钩固定连接为一体,顶端与固定环的底端抵接,通过气压使压杆向下滑动使承压板能紧紧地压住车钩钩锁铁,能有效防止人为原因造成车钩错误开锁,防止脱钩。
