The invention relates to a piano hoisting device which effectively solves the problems that one inclined pull rope above a hoisting frame is suddenly loosened, so that the tension of other inclined pull ropes is too large, and hoisting is difficult to balance. According to the technical scheme, the piano hoisting device comprises a circular ring, supporting rods are arranged at the inner edge of the circular ring, and the supporting rods and the circular ring form the hoisting frame; a sliding groove is formed in the circular ring, four grooves are formed in the sliding groove, and sliding blocks are arranged in the grooves; swing rods are arranged in the grooves, and the swing rods at the two sides are connected through a connecting rope; the two swing rods can be fixed, and the connecting rope is in a tightened state; the swing rod at one side is pushed by a sliding block to swing, the sliding block can be prevented from continuously moving, and the free end of the swing rod at the other side is driven by the connecting rope to leave the sliding groove and enter the groove; fixing devices are arranged at the positions, deviating by 30 degrees, at the two sides of the sliding block, and the sliding block can be clamped by the fixing devices. According to the present invention, the problems that one inclined pull rope above the hanging bracket is loosened suddenly, so that the tension of other inclined pull ropes is too large, and hoisting is difficult to balance, are solved, and a piano is prevented from falling off and being damaged.

    本发明涉及一种钢琴吊装装置,有效解决吊架上方其中一个斜拉绳突然松动造成其他斜拉绳拉力过大和吊装难以平衡的问题;其解决的技术方案是包括圆环,圆环内缘有支杆,支杆和圆环组成吊架;圆环内有滑槽,滑槽上有四个凹槽,凹槽内有滑块;凹槽内有摆动杆,两侧的摆动杆经连接绳相连;两摆动杆能被固定,连接绳处于绷紧状态;一侧的摆动杆受滑块推动而摆动,且能阻止滑块的继续移动,且经连接绳带动另一侧的摆动杆的自由端离开滑槽并进入凹槽内;滑块两侧偏向30度的位置均有固定装置,滑块能被固定装置卡住;本发明解决了吊架上方其中一个斜拉绳突然松动造成其他斜拉绳拉力过大和吊装难以平衡的问题,避免造成钢琴掉落损坏。
