The invention discloses a height limiting device for a travelling crane device and the travelling crane device. The height limiting device is in communication connection with a driving motor, and the height limiting device comprises a data acquisition device and a control device, wherein the data acquisition device is used for acquiring height data; and the control device is used for sending a control signal to the driving motor according to the height data, so that the driving motor is powered off. According to the height limiting device and the traveling crane device, control of a mechanical structure is not involved, and the mechanical limiting device effectively avoids the problem of over-limit safety accidents caused by limit function failure caused by worm fracture caused by worm transmission; meanwhile, according to the height limiting device, a travelling crane driven by the driving motor can be limited to reach any specified height position, and the application range of the height limiting device is greatly expanded; and moreover, according to the height limiting device, an existing mechanical height limiting device can be improved, manufacturing is easy, and the cost is low.
本发明公开了一种用于行车吊装置的高度限位装置和行车吊装置。所述高度限位装置与驱动电机通信连接,包括:数据采集装置,用以采集高度数据;控制装置,用以根据所述高度数据发送控制信号至所述驱动电机,使所述驱动电机断电。根据本发明的高度限位装置和行车吊装置,不涉及机械结构的控制,有效避免了机械式限位装置因为蜗杆传动导致的蜗杆断裂带来的限位功能失效而发生超限位的安全事故的问题。同时,根据本发明的高度限位装置可以对受驱动电机驱动的行车到达任意指定高度位置进行限位,大大扩大了高度限位装置的使用范围。并且,根据本发明的高度限位装置可以在现有的机械式的高度限位装置上进行改造,制造简单、成本低。
