Abstract

The invention discloses a dynamic weighing mechanism for a lifting device based on a comparison method. The dynamic weighing mechanism is effective in dynamic compensation, small in zero drift and high in precision and accuracy. The dynamic weighing mechanism comprises a lifting ring (1), a lifting hook (5) and a shell (9), and is characterized in that an upper bearing plate (2), a cargo weighing sensor (4) and a lower bearing plate (3) are sequentially arranged between the lifting ring (1) and the lifting hook (5); a standard mass block (7) is connected to the lower end face of the upper bearing plate (2) through a standard mass block weighing sensor (6); the dynamic weighing mechanism also at least comprises an accelerometer (8) used for monitoring the weighing environment. The dynamic weighing mechanism is characterized in that center axes of the lifting ring (1), the upper bearing plate (2), the lower bearing plate (3), the cargo weighing sensor (4), the lifting hook (5), the standard mass block weighing sensor (6), the standard mass block (7) and the accelerometer for monitoring the weighing environment coincide with one another in the vertical direction; the shell (9) is coated between the upper bearing plate (2) and the lower bearing plate (3).

Description

technical field

[0001] The invention relates to a dynamic weighing mechanism of a lifting device, which is used for loading and unloading bulk materials at the wharf and for lifting and weighing measurement of goods in power plants, concrete mixing stations, coal yards, sand and gravel yards and cement plants, specifically refers to a method based on comparison method Dynamic weighing mechanism for lifting device. Background technique

[0002] The crane scale in the prior art can only be weighed in a nearly static state after the goods are hoisted stably. In the case of conical rotation, up and down vibration or left and right swing of the cargo, the crane scale cannot weigh accurately. specific combination figure 1 , the most widely used weighing mechanism for lifting devices in the prior art includes four main components: ring 01, load cell 02, hook 03 and housing 04; load cell 02 is connected between ring 01 and hook 03 The ring 01 is located at the upper end of the li...
