Abstract

The invention discloses a double-row chain tightener which comprises a primary shaft (1), a secondary shaft (3), a left hook body (2) and a right hook body (4), wherein the left hook body (2) and the right hook body (4) are arranged on the primary shaft (1) and the secondary shaft (3) at the same time; and a washer (5) and a cotter pin (6) are arranged on the primary shaft (1). According to the double-row chain tightener provided by the invention, the parts needing tightening can be effectively tightened, the processing is simple and the materials are saved.

Description

technical field [0001] The invention relates to a chain tensioner, in particular to a double row chain tensioner. Background technique [0002] The chain tensioner is a chain hanging from a chain, which is easy to break after being stressed, and the link of the hanging chain is also easy to break. Sometimes the rebound force when the chain is broken can easily hit the face of the person connecting the chain, causing many safety accidents. For this reason, the mine has re-improved the chain tensioner in combination with the characteristics of the conveyor head to make it more suitable for the actual operation on site. The size of the pre-tensioning force of the chain of the scraper conveyor not only affects It is also crucial for the normal operation of the conveyor. If the pretension force of the chain is too large, in addition to aggravating the meshing wear between the chain and the sprocket, it will also lead to the increase of no-load consumption and dynamic tension.
