Embodiment
In order that the object, technical solutions and advantages of the present invention are clearer, below in conjunction with the accompanying drawings with specific embodiment pair
The present invention is described in detail.
Embodiment 1
The present embodiment provides the grasping mechanism that a kind of useless filter element replacing transports cell arrangement, including：Gripping apparatus electric cylinder, deceleration
Motor, uni-drive gear box, leading screw, sealing ring, gripping apparatus hang pawl；The leading screw passes through uni-drive gear box, is provided with and grabs at the top of leading screw
Has electric cylinder, bottom is provided with sealing ring, and the gripping apparatus hangs pawl and is placed in below sealing ring, and the reducing motor is arranged on travelling gear
On case, the lifting of leading screw can be controlled by remote electric, the uni-drive gear box is fixed on useless filter element replacing transhipment cell arrangement.
It is preferred that, uni-drive gear box is internally provided with transmission mechanism overload protective device and safe screw；Transmission mechanism overloads
Protector prevents reducing motor overload failure, and safe screw prevents leading screw that wear out failure is used for a long time and falls.
Embodiment 2
As the further supplement to embodiment 1, the application provides a kind of sealing ring, including seal disc and cask flask
Ring, the cask flask ring is connected with useless filter element replacing transhipment cell arrangement, filter core room respectively, plays sealing function；Seal disc
