Problems solved by technology

[0004] In the past, the crane safety system monitored the crane in digital form, such as the large crane of the RCI-1550 system, because the system is a full digital display screen, there are many working conditions of the crane, and these working conditions are all in numbers, codes The form is displayed on the screen, although it is accurate but not intuitive, it cannot meet the safety protection requirements of large and extra-large cranes, it is not conducive to the operator's observation and use, and reduces the reliability of the safe operation of the crane

Embodiment Construction

[0016] The crane safety system detection and control method of the present invention will be described in detail below in conjunction with the embodiments.

[0017] As shown in Figure 1, the crane safety system detection and control method of the present invention includes the following stages:

[0018] The stage of starting the crane and judging whether the system is normal: starting the crane S1; judging whether the system is normal S2, that is, checking whether the signal of the sensor in the system is normal. The setting of the sensor is shown in Figure 2, including the jib installed on the crane , the angle sensor 1 on the main arm and the super lifting mast and the tension sensor 2 arranged on each guy wire. When the system is normal, proceed to the next step; when the system is not normal, display the fault code, sound and light alarm, control the crane not to work, and deal with the fault S3, and then return to S1.

[0019] The stage of judging whether the currently s...

Abstract

The method of detecting and controlling crane safety system includes the following steps: starting the crane and judging the normality of the system, judging whether the set crane condition is the same as the required one, detecting and displaying the current load parameters and comparing with the rated parameters of the crane, receiving the D / A converter signal through the bus, displaying the comparison result and warning, and stopping the crane in case of overload. The present invention is intuitive, accurate and intelligent, and can operate the crane in optimal state.

Description

technical field [0001] The invention relates to an operation control method of a crane. In particular, it relates to a detection and control method for a crane safety system that can intuitively and accurately display the working condition graph of the crane, more precisely control the crane to always run in the best state, and have more economical and reasonable fuel consumption. Background technique [0002] The advent of cranes with a lifting capacity of 400 tons to 1,000 tons has made the idea of ​​overall hoisting of large workpieces a reality, such as the main girder of large bridges, hull segments in the shipbuilding industry, roofs of large stadiums, domes of nuclear power plant reactors and other large workpieces. Therefore, the workload of ground manufacturing of workpieces is greatly increased, the workload of high-altitude assembly is reduced, the installation speed and engineering quality are improved, and the construction process has also undergone earth-shakin...
