Spandrel girder glides along guide groove, until load-bearing plate is placed on hydraulic elevating platform；
2) it according to the height of burning chamber shell, determines the height for needing to keep interval, starts hydraulic elevating platform, when it is arrived
Stop when up to corresponding annular groove location；
3) it is exerted a force by boom hoisting, rolling bearing, so that after the end of spandrel girder enters in annular groove, hydraulic lifting
Platform decline, spandrel girder remove boom hoisting with after annular groove clamping.
Further, it when needing to be adjusted other different size burning chamber shell pouring positions, is risen with lifting appliance
Spandrel girder is hung, annular groove is disengaged it from, then starts hydraulic elevating platform, holds load-bearing plate, rolling bearing enters spandrel girder
Guide groove, further according to needing to rise or fall, so that spandrel girder is rotated back to annular groove can be completed adjustment.
It during propellant casting, is poured in cylinder and necessarily is in vacuum state, and temperature control is at 60 DEG C or so, ring
Border condition is more severe.
Device and method provided by the invention has the advantages that
1, pass through the design of guide groove, it is ensured that the stability of load-bearing plate lifting, while ensure that the end energy of spandrel girder
It is enough accurately to enter annular groove.
2, the application of hydraulic elevating platform may further ensure that the stability and precision of load-bearing plate lifting.It ensures that
Accurate, the efficient casting of propellant, it is ensured that motor grain quality.
The present invention is successfully applied to the burning chamber shell powder charge of 10 kinds of different heights, only with a kind of structure, applies more
A product.The inventive structure rationally, it is reliable operation, easy to operate, completely eliminate various security risks, reduce tooling number
Amount, greatly reduces enterprise's production cost and management cost.
