Device and method for measuring suspended deflection angle and direction of lifting hook of lifting device

Abstract

The invention provides a device for measuring a suspended deflection angle and direction of a lifting hook of a lifting device. The device comprises a suspended deflection angle measuring mechanism, a direction measuring mechanism, a central processing mechanism (9) and a display (8), wherein the suspended deflection angle measuring mechanism is used for measuring the suspended deflection angle of the lifting hook (5); the direction measuring mechanism is used for measuring a rotating angle of the lifting hook (5) on a horizontal plane; the central processing mechanism (9) receives data transmitted from the suspended deflection angle measuring mechanism and the direction measuring mechanism and works out information from the suspended deflection angle and direction data of the lifting hook (5); and the display (8) is connected with the central processing mechanism (9) and is used for displaying the information from the suspended deflection angle and direction data.

Description

technical field [0001] The invention relates to a heavy-duty hoisting device, in particular to a device and a method for measuring the hanging angle and azimuth of the hook of the lifting device. Background technique [0002] As a special equipment for hoisting and transporting goods, cranes have the characteristics of wide range of use, complex working environment and high requirements for safe use. There are many types and structures of cranes, and most cranes have jibs, hoists and hooks. [0003] When hoisting and transporting goods, the crane has a Panasonic hook to hang the sling on the hook in one working cycle, move the hook to hang the hook at an appropriate position above the goods, and use the rigging to hang the goods under the hook. Lift the hook to make the rigging properly tensioned, move the hook to adjust the hanging angle of the hook to be less than the allowable value, lift the hook to make the cargo leave the support surface, and observe the force of the ...

Problems solved by technology

"Integration and Test of Wireless Inclination Sensor for Hook Swing Detection of Large Pipe-laying Vessel" published in the 12th issue of "Journal of Sensing Technology" in 2007 uses the inclination sensor chip installed on the hook to collect hook inclination data and wirelessly transmits them to the computer After processing, the swing angle of the hook is obtained, and it is also impossible to determine the hang deflection angle measured after the hook rotates horizontally around the center line of the wire rope relative to the true orientation of the crane.

[0007] At present, there is no real-time detection instrument and method for measuring the hanging deflection angle of the hook and at the same time determining in real time the hanging deflection angle measured after the hook rotates horizontally around the center line of the wire rope relative to the true orientation of the crane.
