Problems solved by technology

[0006] The inclination sensor only understands the current angle between the vehicle and the horizontal plane, and cannot fully obtain the current support status of each support point. At the same time, the basis for judging the dangerous working conditions of this technology is that the vehicle angle exceeds the limit, but there are certain limitations in determining the specific limit value. difficulty

Abstract

The invention discloses a rollover control method and system and a lorry-mounted crane. The rollover control method comprises the steps that the current suspension system length is collected by displacement sensors, and the current supporting leg pressure is collected by pressure sensors; and a controller controls an alarm device to send out a corresponding indication signal according to the current suspension system length and the current supporting leg pressure. According to the rollover control method and system and the lorry-mounted crane, a driver can be timely and effectively reminded to drive carefully according to the current suspension system length and the current supporting leg pressure which are collected by the sensors, and thus the possibility of lorry-mounted crane rollover accidents is reduced; and operation is easy, control is reliable, and the driver can grasp the supporting state of a vehicle in real time, perceive the vehicle better and thus control the vehicle better, so that risks are avoided.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an overturning control method and system, and a truck-mounted crane. Background technique [0002] As a kind of flexible and convenient construction machinery, truck-mounted cranes are widely used in stations, warehouses, docks, construction sites, field rescue and other places. [0003] When the truck-mounted crane is working, the outriggers and tires share the loading and hoisting load. There are many support points, and there is a problem of rigid-flexible joint support, and the total weight of the vehicle and the position of the center of gravity will change according to the loading status of the vehicle. , Therefore, it is difficult to obtain its specific rollover stability performance from the theoretical aspect. However, truck-mounted cranes usually need to carry out long-arm working conditions. When the hoisting weight is large, if the operator blindly lifts, the tru...
