The invention provides an arm support connecting device and hoisting equipment, and the arm support connecting device comprises a clamping piece which is provided with a locking hole; the locking piece is inserted into or withdrawn from the locking hole, so that the clamping piece and the locking piece are locked or unlocked; the first telescopic driving piece is arranged on the first arm frame, the telescopic end of the first telescopic driving piece is connected with the clamping piece, and the first telescopic driving piece is used for driving the clamping piece to move in the direction away from or close to the first arm frame; and the second telescopic driving piece is arranged on the second arm frame, the telescopic end of the second telescopic driving piece is connected with the locking piece, and the second telescopic driving piece is used for driving the locking piece to be inserted into or withdrawn from the locking hole. The locking piece is driven by the second telescopic driving piece to move, so that the first arm frame and the second arm frame are automatically connected or disconnected, rope pulling operation of a driver under the arm frames in the arm lifting process is replaced, safety is improved, and time and labor are saved. And the first telescopic driving piece drives the clamping piece to move, so that the second arm frame can be separated after reaching a vertical state, opening and closing of the arm frames at different angles are realized, and the risk of backward inclination caused by overlarge angle of the arm frames is avoided.

    本发明提供一种臂架连接装置及起重设备,包括:卡接件,设有锁止孔;锁止件,插入或退出锁止孔,以使卡接件和锁止件锁固或解锁;第一伸缩驱动件,设置于第一臂架上,其伸缩端与卡接件相连,用于带动卡接件沿远离第一臂架或靠近第一臂架的方向运动;第二伸缩驱动件,设置于第二臂架上,其伸缩端与锁止件相接,用于带动锁止件插入或退出锁止孔。通过第二伸缩驱动件带动锁止件运动,从而实现第一臂架与第二臂架自动连接或脱开,代替起臂过程中驾驶员在臂架下进行拉绳操作,提高安全性,省时省力。且通过第一伸缩驱动件带动卡接件运动,可使第二臂架达到竖直状态后将两臂架脱开,从而实现不同臂架角度的开合,避免臂架角度过大产生后倾风险。
