Anti-off mechanism for tower crane suspension shoe, and tower crane
The invention relates to the field of hoisting equipment, and discloses an anti-off mechanism for a tower crane suspension shoe, and a tower crane. The anti-off mechanism comprises the suspension shoeand a pedal, wherein the suspension shoe is hung on the pedal. The anti-off mechanism further comprises a connecting rod and a limiting piece connected to one end of the connecting rod, wherein the connecting rod is rotatably connected to the suspension shoe; and the limiting piece is arranged to be capable of being transformed between a clamping position clamped to the bottom end of the pedal soas to prevent the suspension shoe from being separating from the pedal and a separating position separated from the bottom end of the pedal so as to allow the suspension shoe to be separated from thepedal through the rotation of the connecting rod. According to the anti-off mechanism provided by the invention, through the technical scheme, on one hand, a hole has no need to be opened in the pedal, so that the complexity and the processing cost of a pedal processing technology can be reduced, and the stress condition of the pedal is improved; and on the other hand, during operation, the suspension shoe can be locked and released through rotating the connecting rod, the convenience in operation is realized, and the limiting piece can be further easily rotated to the separating position when the limiting piece is at the stress state, so that time and effort are saved.
本发明涉及起重设备领域，公开了一种用于塔吊挂靴的防脱机构以及塔吊。所述防脱机构包括挂靴和踏步，挂靴挂设于踏步，所述防脱机构还包括连杆和连接于连杆的一端的限位件，连杆可转动地连接于挂靴，限位件设置为能够通过连杆的旋转在卡接于踏步的底端以防止挂靴脱离踏步的卡接位置和脱离踏步的底端以允许挂靴脱离踏步的脱离位置之间转变。本发明的防脱机构通过上述技术方案，一方面无需在踏步中开孔，能够降低踏步加工工艺的复杂度和加工成本，改善踏步的受力状况；另一方面在操作时通过旋转连杆即可实现对挂靴的锁定和释放，操作方便，在限位件处于受力状态时也能够容易地将限位件旋转至脱离位置，省时省力。
