Existing applied unit piece suspension hook has the screw thread chucking, tooth is tightened, or it is rotary simply to twitch one's mouth, no matter any form all can be restrained: the flanging that suspension hook can only block box end 10mm carries out handling.And these suspension hooks all require the flanging place of box and the neutral that the catalyst plates head is reserved one section 6～7mm, can the hook tongue be changeed into.

There are two shortcomings in this type suspension hook: 1. box is in order to advance the hook tongue, and the redundant space of 450X450X7mm will be reserved in the end of box more, like this, and the just circle steel plates that consume of each cell block more.When 2. this hook hypogloeeis falls, the catalyst plates of damaging easily.

Summary of the invention

The purpose of the utility model is to have utilized the spacing space of box inner catalyst board placing to insert the hook tongue, clamps the board-like catalyst elements piece suspension hook of the flanging handling of box end.

The utility model hanging beam is fixedly mounted on the suspension bracket, and suspension hook is connected on the suspension bracket through axle, and the suspension hook outside has the hook that is fixedly mounted on the suspension bracket to protect groove, and the suspension hook bottom is equipped with the hook tongue; Sheave shaft is connected and protects on the frame, protects frame and is fixedly mounted on the hanging beam; The lock tube draw-in groove is arranged on suspension hook; Retracing spring hangs on the hook seat on the suspension hook through hook; Protect at suspension hook and hook and to be with the Lock with hook spring-bolt cover on the groove.

The utility model has been abandoned people's hanging method directly perceived, commonly used, reasonable use the spacing space of box inner catalyst board placing insert the hook tongue, clamp the flanging handling of box end.Therefore, need not reserve the neutral of 6～7mm between the flanging place of box and the catalyst plates head, the hook tongue is by the smooth fillet of reconditioning, and the space between catalyst plates is inserted box and blocked flanging.Safer for handling, more accurately get into the module assigned address, a whole set of suspension hook has designed four little hooks, clamps when preparing lifting into the flanging of box at the suspension hook tongue, sheath locking bail tongue guarantees that the cell block of being sling can loose or dislocation.1. handling is steady, secure.2. the box cost of manufacture can be practiced thrift,, 0.767 ton of cold-rolling steel can be practiced thrift relatively if with gigawatt unit power plant required catalyst elements frame quantity statistics.3. owing to save headspace, reduce flue gas delay whirlpool herein, avoided dust stratification to stop up.4. the utility model also can be applicable to the limited special object handling of hanging piece contour dimension.During the smooth tubular article of past handling gabarit in the workshop, usually hang or tiltedly hang with the rope binding is horizontal, both time-consuming also dangerous, the suspension hook of using this structure is just as safe as a house quick.
