Abstract

The invention relates to a heating furnace, in particular to a roller way chain tensioning device of the heating furnace, and belongs to the technical field of heating furnaces. The device includes a base, the base is connected with a chain pulley seat through a base bolt, the chain pulley seat is connected with a tensioning shaft, the tensioning shaft is connected with a bearing seat through a bearing, and a tensioning chain is fixed on the bearing seat; an oblong adjusting hole is formed in the portion, connected with the base bolt, of the base; the two ends of the bearing seat are connected with a pressing cover through bolts, the pressing cover presses the bearing tightly on the tensioning shaft. The roller chain tensioning device is simple, compact and reasonable in structure, stable and reliable in work and convenient to operate, can adjust the tensioning degree of a roller chain of the heating furnace, and reliable transmission is guaranteed.

Description

Technical field [0001] The invention relates to a heating furnace, in particular to a tensioning device for a roller conveyor chain of a heating furnace, and belongs to the technical field of heating furnaces. Background technique [0002] The heating furnace is a commonly used industrial furnace for heating tube blanks in the production of seamless steel pipes. During production, seamless steel pipes need to be fed into the heating furnace body in turn. The heating furnace roller table is used to transport seamless steel pipes and heat The transmission of furnace roller table adopts transmission chain. In daily use, the transmission chain is easy to relax due to thermal expansion and contraction, resulting in failure of the transmission of the heating furnace roller table. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings, thereby providing a heating furnace roller table chain tensioning device, which can adjus...
