A safety protection system and method for a loading vehicle skeleton working machine

Abstract

The invention discloses a safety protection system of a vehicle framework loading operating machine. The safety protection system comprises a vehicle body monitoring module, a platform monitoring module and a safety protection module, wherein the vehicle body monitoring module is used for monitoring working state information of supporting legs and working state information of a boom; the platform monitoring module is used for monitoring working state information of a platform and working state information of a manipulator; and the safety protection module is used for allowing the boom, the platform and the manipulator to work when receiving the information that the vehicle body monitoring module monitors the situation that the working state information of the supporting legs is an extending state, and is used for allowing the supporting legs to withdraw when receiving the information that the vehicle body monitoring module and the platform monitoring module monitor the situation that the boom, the platform and the manipulator are all in the withdrawing state. According to the safety protection system disclosed by the invention, the working state information of the supporting legs, the working state information of the boom, the working state information of the platform and the working state information of the manipulator are monitored, and through the working state information of the supporting legs, the working state information of the boom, the working state information of the platform and the working state information of the manipulator, the safety protection module judges, whether the supporting legs can withdraw or extend and whether the boom, the platform and the manipulator can withdraw or extend, so that the safety of the equipment is improved. In addition, the invention also discloses a safety protection method of the vehicle framework loading operating machine.

Description

technical field [0001] The invention relates to the field of engineering operations, in particular to a safety protection system and method for a loading vehicle skeleton working machine. Background technique [0002] With the development of industrialization, large-scale operation machinery is popularized in production and construction, which can quickly complete production and construction, and carry out larger-scale material handling, maintenance and construction. [0003] However, as the safety accidents caused by large-scale operating machinery are becoming more and more serious, since large-scale operating machinery is currently operated by humans, all judgments need to be made by the driver. In practical applications, the driver may not be able to Accurately judge the current mechanical operation status, make wrong judgments, and cause accidents. For example, if the outriggers are not extended to the working position, the operation of the workbench and the boom will e...

[0003] However, as the safety accidents caused by large-scale operating machinery are becoming more and more serious, since large-scale operating machinery is currently operated by humans, all judgments need to be made by the driver. In practical applications, the driver may not be able to Accurately judge the current mechanical operation status, make wrong judgments, and cause accidents. For example, if the outriggers are not extended to the working position, the operation of the workbench and the boom will easily cause the entire vehicle body to shake, and even cause the entire vehicle to overturn; work The platform and boom are still working without being retracted, and the retraction of the outriggers due to misoperation may cause the whole vehicle to shake or tip over

The workbench and boom are not retracted in place, and the whole vehicle is put away to exit the working state. The supporting structure of the workbench and boom is under stress, which seriously affects the mechanical life of the workbench and boom; and whether the outriggers are extended to The working position is judged by humans. Whether the outriggers are extended or not, both the boom and the workbench can be operated. This is likely to cause safety accidents due to misoperation. Similarly, when the boom and workbench are working, the outriggers are still It is scalable, but it is also easy to cause misoperation and cause equipment and people to be injured

[0004] Therefore, how to avoid safety accidents caused by human judgment errors and improve the safety of the loading vehicle skeleton operation machine remains to be studied.
