The invention discloses a special lifting appliance for a well type annealing furnace. The special lifting appliance comprises a lifting rod; a movable chuck is arranged at the lower end of the lifting rod; the movable chuck comprises a force bearing plate and sliding clamping blocks; a plurality of clamping grooves are evenly formed in the edge of the force bearing plate; one sliding clamping block is arranged in each clamping groove; and the sliding clamping blocks can retract into the clamping grooves or extend out of the edge of the force bearing plate. The special lifting appliance for the well type annealing furnace can conveniently clamp and loosen annealing material racks, and multiple groups of annealing material racks can be repeatedly lifted by one lifting appliance. In addition, the lifting appliance does not need to be placed into the annealing furnace to be heated together, so that the lifting appliance does not need to be made of heat-resistant stainless steel, and the annealing cost of band saw blades is reduced.
本发明公开了一种井式退火炉专用吊具,包括吊杆,所述吊杆的下端设有活动卡盘,所述活动卡盘包括承力板和滑动卡块,所述承力板的边缘均匀设有多个卡槽,每个所述卡槽内设有一个滑动卡块,所述滑动卡块可收缩至卡槽内或由承力板的边缘伸出。本发明的井式退火炉专用吊具能很方便的夹持和松开退火料架,一个吊具就能反复吊起多组退火料架。并且由于不需要将吊具放入退火炉中一并进行加热,因此吊具不需要采用耐热不锈钢进行制作,从而降低了对带锯条退火加工的成本。
