The invention relates to the technical field of lifting and conveying machines, and discloses a rapid lifting mechanism, a lifting control method thereof, and an aerial work platform. The rapid lifting mechanism comprises a folding part (1) and a variable-amplitude part (2) which are connected with each other. The folding part (1) comprises a vehicle body connecting end. The variable-amplitude part (2) comprises a working bucket connecting end. The folding part (1) can be folded. The variable-amplitude part (2) can change the amplitude. When the folding part (1) performs folding actions, the variable-amplitude part (2) can automatically change the amplitude under the action of the folding part (1) to raise the working bucket connecting end. The folding part comprises a limiting unit for limiting the variable-amplitude limit position of the variable-amplitude part. The limiting unit can resist the variable-amplitude part to limit the limit position of the working bucket connecting end.By means of the rapid lifting mechanism, a working bucket connected to the working bucket connecting end can be effectively prevented from touching the ground any time, the working bucket can be rapidly lifted, performance is reliable, and cost is saved.

    本发明涉及起重运输机械技术领域,公开了一种快速升降机构和高空作业平台及臂架其升降控制方法和高空作业平台。所述快速升降机构包括相互连接的折叠部(1)和变幅部(2),所述折叠部(1)包括车身连接端,所述变幅部(2)包括工作斗连接端,所述折叠部(1)能够折叠,所述变幅部(2)能够变幅;所述折叠部(1)进行折叠动作时所述变幅部(2)在所述折叠部(1)的作用下能够自动进行变幅以抬高所述工作斗连接端;所述折叠部包括用于限制所述变幅部变幅极限位置的限位单元;所述限位单元能够抵挡住所述变幅部以限制所述工作斗连接端的极限位置。利用这种快速升降机构既能在任何时候有效防止连接在所述工作斗连接端的工作斗触地,又能快速升降所述工作斗,性能可靠又节约成本。
