The technical scheme that the present invention takes for the technical problem existing in solution known technology is:
A restorative procedure for overhead chain conveyer C type hook, is characterized in that, comprises the steps:
1) make C type hook maintaining support, maintaining support comprises two base for supporting and is connected to the holding tank of the thickness that can hold C type hook on each base for supporting, between described two base for supporting, be welded to connect channel-section steel at two ends, one of them holding tank top is processed with a locating hole, another holding tank top processes upper and lower two locating holes, distance between described two locating hole center lines is width and the locating hole diameter sum of C type hook, and described locating hole is square opening;
2) the C type hook of distortion is put into the groove of holding tank, wherein blind end is positioned at the holding tank with a locating hole, openend is positioned at the holding tank with two locating holes, alignment pin for limiting the displacement of C type hook is installed, a hydraulic jack of each placement on the base for supporting below C type hook in locating hole;
3) with gas welding, the A district, bottom of C type hook sealing one end is heated, reaching the hydraulic jack below jack-up C type hook opening after uniform temperature, make C type hook opening recover original size;
4) C type hook is pulled down and after Overheating Treatment, recovered its original intensity from support, then continue to use.
Described base for supporting is made up of two I-steel that weld together side by side.
Described holding tank keeps at a certain distance away by two and channel-section steel towards the opposite forms, and the distance between described two channel-section steels can be held the thickness of C type hook.
Between described channel-section steel and base for supporting, be connected by triangle iron plate.
The channel-section steel that limits displacement effect between holding tank between described base for supporting by plaing connects.
Described alignment pin is made up of with the chain being connected on draw ring the draw ring of rectangle bearing pin, rectangle end part of pin shaft.
Advantage and good effect that the present invention has are: the inventive method is simple, easy to use, and the C type hook of distortion is adjusted mechanically, and the C type hook that C type hook is recovered after original machining accuracy reparation can meet need of production completely.
