Summary: | The invention provides a coal cutter tie bar pre-tightening force real-time detection device, and relates to the technical field of detection devices.A longitudinal groove is formed in a guide rail, the guide rail is matched with an adjusting rod, an electric push rod B is installed in the longitudinal groove formed in the guide rail, and a sliding block is installed at the top end of the electric push rod B through a tension sensor; the invention discloses a bolt connection pre-tightening force detection device, and solves the problems that a detection device can only realize manual detection by an operator when detecting the bolt connection pre-tightening force of a tie bar, and an effective real-time detection and early warning structure is lacked, so that the connection failure of a coal mining machine is easily caused when the bolt connection is loosened, and potential safety hazards exist. The electric push rod B installed in the guide rail is started to pull the sliding block to the lower side, the bol |
