The invention provides a pre-tightening and fracture detection device for a flexible transmission chain, and belongs to the technical field of flexible transmission chain tensioning and fracture detection function. The device comprises a shell, a pre-tightening nut arranged in the shell, a nut guide sleeve on the outer layer of the pre-tightening nut, and a pressure spring in transverse contact with the pre-tightening nut. The device also comprises a pre-tightening connector located outside the shell, a fracture detection sensor installed above the shell, an Z-shaped blocking piece arranged between the shell and the fracture detection sensor, and a detection spring, a guide screw for fixing the detection spring, a guide block, a guide block cover plate and a cover plate screw are arranged in the Z-shaped blocking piece. During use, tensioning operation on the flexible transmission chain is completed by rotating the pre-tightening nut, when the corresponding flexible transmission chain breaks down, the compression spring resets, the Z-shaped blocking piece is compressed through the pre-tightening nut, the breakage detection travel switch is further triggered, and a breakage alarm is given out. The device is compact in structure, easy and convenient to install, high in load and high in reliability, and has extremely high application prospects.
Description
technical field [0001] The invention discloses a pre-tightening and fracture detection device for a flexible transmission chain, belonging to the technical field of tension and fracture detection functions of a flexible transmission chain. Background technique [0002] At present, the common flexible transmission chain tensioning device usually adds a tensioning wheel to the transmission of the flexible transmission chain or adjusts the distance between the sprocket wheel shafts. The structure is complicated, the operation is cumbersome, and it is impossible to automatically detect whether the flexible transmission chain is loose or broken during the operation of the equipment, and it is impossible to stop the equipment immediately to avoid equipment damage. Therefore, there is an urgent need for a pretension and fracture detection device for a flexible transmission chain that can adjust the tension of flexible transmission chains such as chains, and can detect whether it is...
