Dynamically measuring device and dynamically measuring method for measuring perpendicularity deviation of hoist lifting hook

Abstract

The invention relates to a dynamically measuring device and a dynamically measuring method for measuring the perpendicularity deviation of a hoist lifting hook, wherein the dynamically measuring device is characterized by comprising a horizontal measurement sensor, a signal receiving and transmitting mechanism, a center processing mechanism and a display mechanism, wherein the horizontal measurement sensor is installed on the plane perpendicular to the center line of a steel cable of a hoist lifting hook and used for measuring an angle of the steel cable of the hoist lifting hook deviating from the horizontal plane; the signal receiving and transmitting mechanism collects and transmits data measured by the horizontal measurement sensor; the signal receiving and transmitting mechanism transmits the collected data to the center processing mechanism, and the center processing mechanism acquires a calculation result by calculation; and the display mechanism displays the calculation resultcalculated by the center processing mechanism. The measuring method adopting the device is simple and convenient. Compared with the prior art, the invention can dynamically measure the perpendicularity of the lifting hook in real time, has high measuring precision, overcomes the adverse effect of measurement and improves the hoisting safety.

Description

technical field [0001] The invention relates to the hoisting of large-scale equipment, in particular to a dynamic measuring device and a measuring method for the verticality deviation of a hook of a large-scale crane. Background technique [0002] The hoisting of large equipment ranges from hundreds of tons to thousands of tons. It is very important to control the hook to be in a natural vertical state after such equipment is hoisted. Otherwise, the equipment is prone to swing and may injure nearby equipment. equipment and personnel. [0003] The current method of controlling the verticality of the hook is grasped by the naked eye of the lifting commander and years of time experience. When a small crane is hoisted, it can generally be controlled within a 2° deviation; for a large crane, due to its long boom, people standing near the hook will cause visual errors. It is necessary to judge whether the hook is naturally vertical or not. , with great difficulty. This may caus...

Problems solved by technology

[0005] Since the hook is always in motion during the hoisting process, the detection of its verticality has certain particularities. At present, there is no detection instrument and method for the natural verticality of the dynamic hook.
