Abstract
The utility model discloses a load-limiting type tensile force measuring device and relates to the field of tensile force measuring technology. The outer end surface of the left end of a connecting piece B (11) is sleeved with a belleville spring (10). The left end of the belleville spring is connected with the right end of a connecting piece A (6). In this way, during the running process of the measuring device, the normal load of a steel wire rope, expressed in the form of the amount of elastic deformation of the belleville spring, is measured through a weighing sensor and then is transmitted to a master control system. When a nonconventional load is supported on the measuring device, the weighing sensor is still ensured to be protected from over-range indication. The load-limiting type tensile force measuring device is simple in structure and convenient in both maintenance and replacement of spare parts, and is suitable for large-scale popularization and application.
