Problems solved by technology
At present, for the measurement of the traction force of the winch, it is generally to install a tension sensor on the base of the winch to indirectly measure the magnitude of its traction, because this measurement method does not consider the friction between the winch itself and the ground, and the friction The force is related to the condition of the ground, so there is a large measurement error in this measurement method, and the measured results cannot accurately reflect the real traction force of the winch mill

Description
technical field [0001] The invention relates to a pulling force detection device, in particular to a portable telemetry device for pulling force of a winch mill. Background technique [0002] Winch mill is a kind of construction machinery without power supply in the field. It is widely used in engineering construction such as hoisting, traction or hauling in fields such as electric power, communication, construction, docks, mines, and forests. The equipment is driven by a diesel engine or a gasoline engine, and after being shifted by a gearbox, the wire rope is driven by the winch drum to pull the load to move. Since the load changes greatly during construction, if the pulled load exceeds its rated traction force, it will cause damage to the winch mill due to overload operation, and may damage the winch mill in severe cases, or cause casualties due to the wire rope breaking Situation happens. For this reason, the actual traction force of the winch must be detected in real ...
