Embodiment Construction

[0034] see figure 2 As shown, the automobile crane motion control system of the present invention includes the automobile crane and the safety control system of the automobile crane. , outriggers, chassis and counterweight. The car crane is a kind of crane installed on the chassis of ordinary cars or special cars, and its driving cab is set separately from the lifting control room. The advantage of this kind of crane is good maneuverability and quick transfer. Shortcoming is need supporting leg during work, can not load travel, is also not suitable for working on soft or muddy ground, and truck crane is a prior art product. The safety control system of the truck crane is composed of boom control system, spreader control system, travel control system, vehicle conventional control system and safety protection system and other subsystems:

[0035] 1) The boom control system, including the boom, pitching hydraulic cylinder and telescopic hydraulic cylinder, adjusts the pitch a...

Abstract

The invention discloses a motion control system for an automobile crane and a safety control method for the motion control system. The motion control system comprises the automobile crane and a safetycontrol system for the automobile crane, and the safety control system for the automobile crane is composed of a cantilever crane control system, a lifting appliance control system, a walking controlsystem, a conventional vehicle control system, a safety protection system and the like. According to the motion control system and the safety control method thereof, when safety control is carried out on the automobile crane, CAN bus control is introduced, the CAN bus protocol is a structurally open and broadcast type network communication protocol, and a CAN bus is called a controller local areanetwork field bus; and as the controller local area network bus with a good application potential, in recent years, the CAN bus is more and more widely applied to the fields of automobile computer control systems, textile machinery, packaging machinery, papermaking machinery, agricultural machinery, engineering machinery, robots and other open type distribution intelligent control.

Description

technical field [0001] The invention belongs to the field of construction machinery, and in particular relates to a vehicle crane motion safety control system and a control method thereof, which are suitable for use in construction crane safety control. Background technique [0002] Truck cranes (referred to as truck cranes) are mainly used in engineering teams, construction industries, and power installation departments such as roads, bridges, construction, and emergency rescue. The truck crane safety control system is a system that provides a highly reliable safety protection method, which can avoid the unsafe state of related equipment to the greatest extent, prevent the occurrence of vicious accidents or reduce losses as much as possible after the accident, and protect the production equipment. and most importantly personal safety. However, the traditional control system currently used in the movement safety of truck cranes has the following deficiencies: (1) The commun...
