Novel hoisting equipment with weighing sensors, and weighing method

Abstract

The invention discloses novel hoisting equipment with weighing sensors. The novel hoisting equipment with the weighing sensors comprises a hoist walking track, a bridge and a hoisting trolley, whereinthe hoisting trolley comprises a separated type frame and a lifting mechanism arranged on the separated type frame; the separated type frame comprises an upper frame and a lower frame; the four groups of same frame weighing sensors are distributed between an upper frame support beam and a lower frame support beam; a rope guiding device is arranged on a roll drum through a roll drum screw thread;the upper end and the lower end of a pressing plate of the rope guiding device are protruded outwards; and a hoisting object balance device is connected under the pressing plate of the rope guiding device through a hoisting object balance device connecting plate. According to the novel hoisting equipment with the weighing sensors provided by the invention, the weight of the hoisted cargo can be accurately acquired, meanwhile, the advantage of keeping the cargo stability during the hoisting process is realized, the structure is simple, and an existing bridge crane can be conveniently reconstructed at low cost.

Description

technical field [0001] The invention relates to a lifting device, in particular to a bridge crane equipped with a weighing sensor device and a weighing method. Background technique [0002] At present, lifting equipment is widely used in various construction sites, which can lift vertically and move heavy objects horizontally within a certain range, greatly improving work efficiency. [0003] Bridge crane is a kind of lifting equipment that can be placed horizontally over the working environment such as workshop, warehouse and stockyard and carry out material lifting. The bridge crane mainly includes the crane walking track, the bridge frame and the lifting trolley. The bridge frame includes two sets of main girders and two sets of end beams connected to form a rectangle. The trolley driving device is driven to run along the length of the crane's walking track; the cart driving device is mainly composed of a cart driving motor, transmission shaft, reducer, wheels and brakes...

AI Technical Summary

Problems solved by technology

However, after the existing bearing seat type load cell works for a long time, the mechanical properties of the strain gauge of the load cell will change due to the long-term force, resulting in inaccurate measurement results, and it is unable to provide any auxiliary measurement solutions. discontinued replacement

[0005] On the other hand, the existing hoisting equipment drives the steel wire rope wound on the reel to lift the goods through the hoisting motor. Because the steel wire rope has a certain degree of flexibility, shaking and swaying will occur during the lifting of the goods, which will cause a certain degree of vibration in the reel. Displacement results in inaccurate weighing measurements

At the same time, the phenomenon of shaking and swaying during the lifting of the goods will also cause great safety hazards to the lifted goods, such as hitting the materials stacked on the ground, or the steel wire rope hitting the main beam of the bridge, etc.

At the same time, in the case of garbage transportation and hoisting, the garbage in the grab bucket will also be spilled, resulting in a great deviation between the initial weight data measured by the load cell and the actual lifting weight data
