Abstract

A tensioning sprocket and a broken chain detection device, including a base, a sleeve device, a spring, a tensioning sprocket, a sprocket frame, a tensioning sprocket adjustment device, and a limit switch; the sleeve device includes a sleeve base and a sleeve The sleeve, the base of the sleeve is connected with the base; the spring is installed inside the sleeve; the tensioning sprocket is installed on the sprocket frame, the left end of the sprocket frame is provided with a sliding shaft, the sliding shaft is inserted into the right end of the sleeve, and the spring at the left end of the sliding shaft The right pressure plate is connected with the right end of the spring; the tensioning sprocket adjustment device includes a sprocket adjustment bolt, a screw plug, and a spring left pressure plate. The left end of the spring is connected; the limit switch is installed at the right end of the base; the front end of the sprocket frame is provided with a limit switch strike plate. The device of the invention can not only realize the function of chain rotation and tensioning the sprocket, but also can detect whether the transmission chain is detached or broken, thereby improving the safety and reliability of the chain transmission.

Description

technical field [0001] The invention belongs to the technical field of chain detection, and in particular relates to a tensioning sprocket and a broken chain detection device. Background technique [0002] Due to the high lifting height of large-scale gantry cranes, the lifting reels are generally set to be wound in double layers in the same direction, and a rope arrangement is provided to ensure the deflection angle of the lifting wire rope on the reel and make the wire rope on the reel. It can be arranged neatly, and the rope row device and the lifting drum of the rope row mechanism are driven by a chain to ensure synchronous action. The schematic diagram of the structure of the hoisting drum and the rope arrangement mechanism of the large-scale gantry crane is as follows: figure 1 As shown, it includes a lifting reel 01, a rope arrangement 02, an upper sprocket device 03, and a lower sprocket device 04. The upper sprocket of the upper sprocket device 03 is coaxially conn...
