Weighing method based on force acquisition from amplitude varying steel wire rope

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] The luffing force refers to taking the tension on the luffing steel wire rope. It adopts the ordinary plate ring sensor and installs it on the fixed end of the luffing rope or on the bracket of the luffing pulley block. Refer to the attached figure 1 . According to the torque balance relationship of luffing rope tension, hoisting rope tension, boom self-weight, and load gravity, multiple parameters are determined through the operation of the commissioning site, and then the load gravity is calculated according to a set of algorithms, so as to achieve the weighing and weight of the load.
