Mobile vehicle-mounted concrete pump dual-pump confluence intelligent control system

Abstract

The invention relates to a dual-pump confluence intelligent control system of a mobile vehicle-mounted concrete pump, in particular to electrical automation control of engineering vehicles, and belongs to the technical field of automatic control. In the present invention, the input terminal of the programmable controller PLC in the centralized control distribution box is connected to the control signal, the output terminal of the programmable controller PLC is connected to the relay, and the relay is respectively connected to the control executive device, the vehicle power supply and the power supply, and the programmable control The analog output port of the controller PLC is connected to the CAN bus of the Beiben chassis. The present invention, through the PLC control system of the programmable controller, can separately complete the ability to control each action when the diesel engine and the electric motor work alone, can realize the mutual switching between the vehicle power supply and the power supply, and can realize the simultaneous operation of the electric motor and the diesel engine The unique dual-pump confluence control capability prolongs the service life of the vehicle's electronic control system and greatly improves the construction efficiency, reliability and practicability of the concrete pump.

Description

technical field [0001] The invention relates to a dual-pump confluence intelligent control system of a mobile vehicle-mounted concrete pump, in particular to electrical automation control of engineering vehicles, and belongs to the technical field of automatic control. Background technique [0002] The mobile vehicle-mounted concrete pump belongs to construction machinery, which is suitable for large-area continuous pouring of concrete in railways, bridges, and high-rise buildings. The chassis is equipped with a pumping system and a diesel engine, and the diesel engine is the power source. This type of vehicle-mounted pump is flexible in application and is not limited by site conditions, but it needs to be attached to the engine. The other is a towed concrete pump with an electric motor as the power source. The equipment requires the construction site to be equipped with a power supply, and mechanical drag is required when moving, so the flexibility is limited to a certain e...

AI Technical Summary

Problems solved by technology

[0004] 1) The power of the vehicle-mounted engine is limited, and it cannot fully meet the needs of the project when a large amount of continuous operation is carried out on the construction site of high-rise buildings and viaducts, which reduces the construction efficiency and limits the scope of application.

At the same time, the two engines have high energy consumption and high noise

[0005] 2) The towed electric concrete pump has a large power and can work continuously, but it needs a power source. It cannot give full play to its advantages in some field construction or construction sites without power source, and its application is limited.

[0006] 3) There are too many connecting lines in the relay control system

When the working environment is harsh, the amount of vibration generated is large, and it is easy to cause disconnection, disconnection and looseness, which will affect the normal use of the product
