Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.

The embodiment of the application provides a method for early warning dangerous hanging objects of an overhead travelling crane, which comprises the following steps as shown in figure 1:

step S101: and obtaining the inclination direction and the inclination angle of the steel wire rope on the crown block. Specifically, the steel wire rope is a steel wire rope of a fixed pulley block in a hoisting mechanism on the overhead travelling crane, and the inclination direction and the inclination angle of the steel wire rope can accurately reflect whether the overhead travelling crane has dangerous hanging objects such as inclined hanging and the like and the damage degree.

Step S102: and judging whether the inclination angle is larger than a preset angle threshold value. When the inclination angle is larger than the preset angle threshold, executing step S103; when the inclination angle is smaller than or equal to the preset angle threshold, the process returns to step S101.

Step S103: the corresponding duration is obtained.

In a specific embodiment, the time when the inclination angle is greater than the preset angle threshold for the first time may be recorded as the start time; the tilt angle is then acquired again according to a preset time step. And repeatedly executing the acquisition of the inclination angle until the inclination angle acquired again is smaller than or equal to the preset angle threshold. When the angle of inclination of reacquiring is still greater than the preset angle threshold, after the corresponding time step is accumulated from the starting time, the corresponding duration can be calculated. When the angle of inclination collected again is smaller than or equal to the preset angle threshold, clearing the start time and the duration recorded at present, and when the angle of inclination gradually increases and is larger than the preset angle threshold, re-marking the corresponding start time and duration.

Step S104: and judging whether the duration reaches a preset time interval or not. When the duration reaches the preset time interval, executing step S105; when the duration time does not reach the preset time interval, the process returns to step S101.

Step S105: and generating a corresponding early warning signal according to the inclination direction.

In practical application, under the condition that the inclination angle and the duration of the steel wire rope reach the early warning condition, the running direction of the crown block can be further obtained. And when the running direction of the crown block is consistent with the inclination direction, generating a corresponding early warning signal, wherein the early warning signal comprises an instruction for prohibiting the crown block from continuing running along the inclination direction, so that the inclination angle of the steel wire rope is further increased by comparison.

In order to effectively monitor the dangerous hanging object of the overhead travelling crane, in practical application, the detection data of the inclination angle, the inclination direction, the duration time of the steel wire rope, the running direction of the overhead travelling crane and the like can be sent to the specified terminal equipment in real time, for example, the preset intelligent terminal equipment such as a mobile phone, a tablet personal computer and the like.

When a crane driver drives a crane to operate, the crane driver cannot observe whether a person passes behind the crane driver in a cab or the person possibly suddenly appears in a stock yard when the crane lifts an object, so that the risk of smashing and crushing the person by the lifted object exists. Therefore, the image in the preset range below the crown block can be obtained while the inclination angle and the inclination direction of the steel wire rope are monitored. And when the personnel exist in the image, generating a corresponding early warning signal.

In order to facilitate the maintenance operation of the crown block, when the crown block is in a maintenance state, the monitoring of the steel wire rope and personnel below the crown block is temporarily interrupted in a mode of manually inputting instructions, and no early warning signal is generated.

According to the early warning method for the dangerous hanging object of the overhead travelling crane, the steel wire rope of the fixed pulley block in the hoisting mechanism on the overhead travelling crane is monitored in real time, the inclination angle of the steel wire rope is collected, and an early warning signal is sent out in time under the condition that the inclination angle is too large, so that risks of dangerous hanging objects such as inclined-pulling and inclined-hanging of the overhead travelling crane are prevented and controlled.

It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

When the inclination angle is greater than the preset angle threshold, the early warning unit 202 is configured to generate a corresponding early warning signal according to the inclination direction; the corresponding working process can be referred to the steps S102 to S105 in the above method embodiment.
