Problems solved by technology

When the crane is actually in use, it cannot be detected online. When the structural displacement index of the crane exceeds the standard, it cannot be controlled, which brings great hidden dangers to the driver and the lifting equipment itself.
In actual use, due to violations of regulations and simple pursuit of economic benefits without considering the working limit of the equipment, it is easy to cause the collapse of the crane and casualties, and major safety production accidents occur from time to time

Embodiment Construction

[0014] Referring to accompanying drawing 1, the steps of the online measurement method for the structural displacement of the tower crane are as follows:

[0015] 1. Install the angle sensor at the hinge point at the root of the boom of the tower crane.

[0016] 2. Use the angle sensor to detect the angle change of the root of the boom and convert it into an analog electrical signal.

[0017] 3. Angle change The analog electrical signal is converted into a digital signal that can be processed by the single-chip microcomputer through the analog input interface circuit and the A / D conversion circuit.

[0018] 4. Angle change The digital electrical signal is connected to the single-chip microcomputer, and after being processed by the corresponding mathematical model, the horizontal change of the root of the boom is obtained, that is, the structural displacement of the tower crane.

[0019] In actual application, use theodolite or other equipment to measure the two horizontal cha...

Abstract

An in-line measuring method for the structural displacement of tower crane includes such steps as arranging an angle sensor at the pivoted root of gibbet, detecting the angle variation of gibbet, A / D conversion to become digital signal, inputting the digital signal to single-chip processor, and processing by mathematic model to obtain the structural displacement.

Description

technical field [0001] The invention relates to an online measurement method for the structural displacement of a tower crane, belonging to the technical field of measurement control. Background technique [0002] In construction, electric power, water conservancy, petrochemical, mining and other industries, it is generally necessary to use a large number of cranes for lifting, transportation, loading and unloading. Especially in construction projects, the amount of lifting and installation is quite large, and engineering cranes are required to lift and carry large volumes. , heavy weight of various equipment and raw materials, so its safety is very important. For this reason, the country has listed hoisting machinery as special equipment with high safety and danger, and has formulated strict specifications and regulations from design to production. National mandatory standards. The national standard has strict regulations on the safety of cranes, and stipulates various saf...
