Device for monitoring tensile force of cable on wharf bollard

The utility model belongs to the technical field of wharf bollards, particularly relates to a device for monitoring the tensile force of a mooring rope on a wharf bollard, and aims to solve the problem that the fixing condition of a ship body cannot be monitored in extreme weather such as fierce wind due to the fact that the tensile force of the mooring rope cannot be well monitored when the conventional wharf bollard is used. According to the technical scheme, the device comprises a base, a pile foundation is slidably connected to the top of the base, a clamping head is fixedly installed at the top of the pile foundation, a clamping mechanism is arranged on the pile foundation, a mounting base is rotatably connected to the bottom of the base, a positioning mechanism is arranged on the mounting base, and the positioning mechanism is matched with the base. A mounting block is mounted on the base, a groove is formed in the bottom of the mounting seat, and the mounting block is located in the groove. The cable t
