The invention relates to the field of aerial work devices, and discloses a weighing device for an aerial work platform and an aerial work device. The weighing device for the aerial work platform comprises a transition base (10) used for being connected with a swing arm, a supporting frame (20) used for being connected with the work platform, a weighing unit (30) and at least two connecting rods (50). Each connecting rod spans between the transition base and the supporting frame and, and the connecting rods are connected with the transition base and the supporting frame through hinge pins (60)respectively. The weighing unit is installed on one of the transition base and the supporting frame, and the other one of the transition base and the supporting frame is provided with a positioning structure (40) used for positioning the weighing unit through pre-tightening force in the vertical direction. By means of the weighing device, the weighing unit can be stably positioned in the verticaldirection through the positioning structure, the situation is prevented that the work table drives the supporting frame to bounce to cause separation from the weighing unit, and collision is thus resulted. Therefore, the weighing precision can be ensured, and the service life can be prolonged.
本发明涉及高空作业设备领域,公开了一种高空作业平台称重装置和高空作业设备,其中,所述高空作业平台称重装置包括用于连接摆臂的过渡座(10)、用于连接工作平台的托架(20)、称重单元(30)和至少两个连杆(50),每个连杆横跨在过渡座和托架之间并分别与过渡座和托架通过销轴(60)连接,称重单元安装于过渡座和托架中的一者,过渡座和托架中的另一者上设置有用于沿竖直方向以预紧力定位称重单元的定位结构(40)。本发明可以通过定位结构对称重单元提供竖直方向的稳固定位,避免了工作平台带动托架的跳动导致与称重单元脱离和随之产生的碰撞,因而能够保证称重精度和延长使用寿命。
