Container reach stacker engine rotating speed control device and method

Abstract

The invention discloses a container reach stacker engine rotating speed control device. The container reach stacker engine rotating speed control device comprises a vehicle controller, an accelerator mode selection switch, an electronic accelerator pedal, an operation handle, a large arm proportional electromagnetic valve and a lifting appliance electromagnetic valve, wherein the vehicle controller is used for controlling a vehicle; the input of the vehicle controller is connected with the accelerator mode selection switch, the electronic accelerator pedal and the operation handle; the output end of the vehicle controller is connected with the large arm proportional electromagnetic valve and the lifting appliance electromagnetic valve; the accelerator mode selection switch and the electronic accelerator pedal are used for selecting an accelerator mode and controlling the magnitude of an accelerator; the operation handle is used for performing man-machine interaction, receiving an operation signal and controlling the large arm proportional electromagnetic valve to act; the output end of the large arm proportional electromagnetic valve is connected with a reach stacker large arm; the large arm proportional electromagnetic valve is used for controlling the reach stacker large arm to act; and the lifting appliance electromagnetic valve is connected with a lifting appliance and is used for controlling the lifting appliance to act. According to the container reach stacker engine rotating speed control device and method, the rotating speed following performance of an engine is good, flameout is not prone to occurring, the operation efficiency of the vehicle is further improved, energy consumption is reduced, and meanwhile, the operation comfort of a driver is improved.

Description

technical field [0001] The invention relates to the technology for controlling the rotational speed of a front-mounted engine, in particular to a rotational speed control device and a control method for a container-mounted front-mounted engine. Background technique [0002] Reach stacker is the abbreviation of container reach crane. Reach stacker is a kind of mobile crane used to load and unload containers. It belongs to a kind of lifting equipment, and it can also be said to be a kind of mobile machinery. The working device of the reach stacker is mainly composed of a telescopic and variable boom and a spreader installed at the front end of the boom. The boom can be lifted, lowered, extended and retracted, and the spreader can be stretched, moved sideways and rotated. And the twist lock action, combined with the action of the arm, can realize the lifting and stacking operations of different standard containers; the above actions of the arm and the spreader are to send signa...

AI Technical Summary

Problems solved by technology

The working device of the reach stacker is mainly composed of a telescopic and variable boom and a spreader installed at the front end of the boom. The boom can be lifted, lowered, extended and retracted, and the spreader can be stretched, moved sideways and rotated. And the twist lock action, combined with the action of the arm, can realize the lifting and stacking operations of different standard containers; the above actions of the arm and the spreader are to send signals to the vehicle controller by operating the electric control handle, and the vehicle controller outputs electrical signals to the electromagnetic The valve makes it move, and then by stepping on the electronic accelerator pedal, the engine drives the hydraulic pump to input the hydraulic oil to each action cylinder through the solenoid valve, so that the boom and the spreader move; in this process, the driver needs to operate the electric Control the handle and step on the electronic accelerator pedal, which is labor-intensive

Moreover, when the driver is working with heavy loads, if he first operates the handle to open the solenoid valve and then steps on the electronic accelerator to accelerate the engine, the sudden increase in load will cause the engine to stall; if he first steps on the electronic accelerator and then operates the handle, it will cause engine consumption can increase

[0003] In order to solve the above problems, the engine speed is controlled by load, that is, the engine speed is increased as the load increases. This control has poor engine speed followability and is easy to stall. Step on the electronic accelerator pedal
