Method, device and system for movable hoisting machinery rollover protection

Abstract

The invention discloses a method, device and system for movable hoisting machinery rollover protection for improving operating security of the movable hoisting machinery, wherein the method comprises the following steps of: acquiring first operating parameter information of an arm frame of the movable-hoisting machinery through a first detection device, acquiring forerake parameter information of a vehicle body of the movable hoisting machinery through a second detection device and acquiring second operating parameter information of a derricking cylinder of the movable hoisting machinery through a third detection device; using a torque balance equation to determine the gravity information of an object hoisted by the movable hoisting machinery by according to the first operating parameter information, the forerake parameter information and the second operating parameter information; and outputting a rake alarm indication so that the movable hoisting machinery cuts operations in the rake direction if the physical value corresponding to the gravity information is greater than the set threshold.

Description

technical field [0001] The invention relates to the technical field of heavy machinery, in particular to a method, device and system for overturning protection of mobile hoisting machinery. Background technique [0002] The reach stacker is a kind of lifting and transportation equipment that can move containers horizontally and vertically. It is widely used in ports, docks, railway and highway transfer stations, and storage yards. It has dual functions of forklifts and truck cranes. The operation actions of the reach stacker generally include: lifting, lowering, jib extension, jib retraction and hoisting travel, generally there is no turning action. [0003] Such as figure 1 As shown, the reach hanger includes: boom 1, car body 4, rear wheel 5, luffing cylinder 6, and front wheel 9, wherein the luffing cylinder 6 pushes the jib 1 to rise or fall, and the jib 1 is more The joint arm combination is generally a combination of two joint arms, wherein the first joint arm is a f...

Problems solved by technology

[0004] However, because the tires support all the weight, and the heavy objects are always in front of the equipment, the pressure on the front wheels 9 is obviously greater than that on the rear wheels 6, causing the front wheels to sink and the vehicle body to lean forward.

In addition, when the front crane is driving with heavy loads, the inclination angle of the vehicle body is more obvious due to the uneven road surface.

However, the existing anti-rollover mechanism does not consider the inclination angle of the front crane body, resulting in the potential safety hazard of overturning caused by the inclination of the body

[0005] It can be seen that there is still a potential safety hazard of overturning during the operation of the existing reach stacker, and the safety is not high

For other mobile hoisting machinery, there is also a potential safety hazard of the vehicle body overturning during the flow process due to the inclination angle of the vehicle body
