Control system, method, device and crane in safe driving area of ​​crane

Abstract

The invention relates to the technical field of hoisting machinery and discloses a system, a method and a device for controlling a safe driving area of a hoist and the hoist. The system for controlling the safe driving area of the hoist comprises a positioning control device and a speed control device, wherein the positioning control device is used for determining a current position of the hoist; the speed control device is in signal connection with the positioning control device and is used for determining a current distance between the current position and a set safe center position; when the current distance is greater than a first set value and a first set duration is maintained, a gearbox speed reducing signal is output to control the hoist to reduce the speed. According to the technical scheme, the driving position of the hoist does not need to be manually supervised, the labor cost is greatly reduced, the dangerous situation probably caused by driving of the hoist out of the safe driving area can be prevented, and the operating safety of the hoist is further improved.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to a control system, method, and device for a safe running area of ​​a crane and a crane. Background technique [0002] At present, in the field of construction hoisting machinery, cranes are used more and more frequently, and the business model that customers hand over cranes to users through employment is becoming more and more popular in the market. At this stage, when the customer specifies the safe working area of ​​the crane and hands over the crane to the user, the user may work outside the safe working area of ​​the crane during the use of the crane, which may cause unexpected accidents. Dangerous situation, it is difficult to guarantee the personal safety of the crane operator and the surrounding people. Therefore, for cranes without intelligent monitoring systems, customers need to assign professional technicians to the construction site for supervision, which ...

Problems solved by technology

At this stage, when the customer specifies the safe working area of ​​the crane and hands over the crane to the user, the user may work outside the safe working area of ​​the crane during the use of the crane, which may cause unexpected accidents. Hazardous situation, difficult to ensure the safety of the crane operator and those around him

Therefore, for cranes without intelligent monitoring systems, customers need to assign professional technicians to the construction site for supervision, which increases labor costs; Customers need to conduct 24-hour uninterrupted monitoring based on the positioning information provided by GPS. 24-hour uninterrupted monitoring not only consumes a lot of human energy, but even if the GPS finds that the crane exceeds the designated operating area, it cannot control the occurrence of such situations in time.

[0003] The defect of the prior art is that during the operation of the crane, it is necessary to manually supervise the driving area of ​​the crane, therefore, a large amount of labor costs are consumed, and the crane exceeding the safe driving area may cause danger to the surrounding personnel, which increases the danger of the crane operation
