Apparatus for real-time detection of crane loading

Abstract

The invention relates to an apparatus for real-time detection of crane loading, which comprises a signal acquisition end and a signal analysis end, a weighing sensor is arranged at the connection position of a crane wire rope and a suspension hook by the signal acquisition end, the output of the weighing sensor is accessed to a CC2430 module through an amplifier and an AD converter, the CC2430 module emits the output value by using a wireless mode, the signal analysis end comprises a microprocessor with coordinator knot point, and receives the signals emitted by the CC2430 module by the wireless mode, and the microprocessor is connected to a memory and a display. According to the invention, load capability of the wire rope enables on-line detection, the faults such as overloading and unbalance of the crane can be eliminated, the installation and debug are simple, the maintenance cost is low, and the wireless mode provides more convenience to a monitor part.

Description

[0001] technical field [0002] The invention relates to the field of on-line detection of crane parameters, in particular to a device for real-time detection of crane load. Background technique [0003] In the process of industry and construction, it is necessary to use cranes to lift heavy objects. With the development of technology, the weight of objects lifted by cranes and the lifting speed have been greatly improved. Cranes often need to work at full capacity, so In the process of hoisting, there are often phenomena such as unstable power unit, too fast hoisting / lowering speed, broken wire rope, and sudden drop of cargo, which pose great safety hazards, and these hidden dangers are mostly related to the hoisting load of the wire rope. At present, the method of shutting down for maintenance and regular replacement is used to avoid the transmission of related accidents. On the one hand, this method causes waste, and on the other hand, the shutdown also causes losses to t...

[0003] In the process of industry and construction, it is necessary to use cranes to lift heavy objects. With the development of technology, the weight of objects lifted by cranes and the lifting speed have been greatly improved. Cranes often need to work at full capacity, so In the process of hoisting, there are often phenomena such as instability of the power unit, too fast hoisting / lowering speed, broken wire ropes, and sudden drop of cargo, which pose great safety hazards, and these hidden dangers are mostly related to the hoisting load of the wire rope.

At present, the method of shutting down for maintenance and regular replacement is used to avoid the transmission of related accidents. On the one hand, this method causes waste, and on the other hand, the shutdown also causes losses to the construction party, and it is also prone to missing inspections and sudden fractures. The occurrence of accidents cannot be fundamentally avoided
