Novel screw hoist
The invention is applicable to the technical field of water conservancy machinery hoists, and provides a novel screw hoist. The novel screw hoist comprises a machine head, a transmission nut and a screw rod; a speed reduction transmission mechanism is arranged in the interior of the machine head, the transmission nut is arranged in the interior of the machine head and is fixedly connected with thespeed reduction transmission mechanism; the screw is in threaded connection with the transmission nut and used for driving a gate to be opened and closed; an electric device is arranged on the machine head, the electric device comprises a servo motor and a planetary reducer, the planetary reducer is connected with the servo motor, the planetary speed reducer is arranged on the machine head, is connected with the speed reduction transmission mechanism and is used for driving the transmission nut to rotate; and an integrated controller used for controlling the action of the hoist and displayingthe working state of the hoist is further arranged on the machine head. According to the embodiment of the novel screw hoist, a mode that the servo motor and the planetary reducer are combined is adopted; in cooperation with the speed reduction transmission mechanism, the requirements of the hoist on the torque and the rotating speed are easily met; the structure is compact, the transmission efficiency is high, and the service life is long; and the design and matching are very convenient.
本发明适用于水利机械启闭机技术领域，提供了一种新型螺杆式启闭机，包括机头，其内部设有减速传动机构；传动螺母，设于机头内部，并与减速传动机构固定连接；螺杆，与传动螺母螺纹连接，用于带动闸门开启、关闭；其中，机头上设有电动装置，电动装置包括伺服电机和行星减速机；行星减速机与伺服电机连接；行星减速机安装在机头上并与减速传动机构连接，用于带动传动螺母转动；机头上还设有用于控制启闭机动作和显示启闭机工作状态的集成控制器；本发明实施例采用伺服电机与行星减速机组合的方式，配合减速传动机构，很容易满足启闭机对转矩、转速的要求，而且结构紧凑、传动效率高、使用寿命长，设计选配十分方便。
