Abstract
The invention discloses an electric control device of a gas power hydraulic excavator. The electric control device comprises a hydraulic system controller and a monitoring system controller. A gas engine controller is provided with a rotation speed sensor connected with the hydraulic system controller. The rotation speed sensor is connected with a proportional magnetic valve. The monitoring system controller is connected with a liquid level sensor. The hydraulic system controller is connected with an accelerator knob. The monitoring system controller, the hydraulic system controller and the gas engine controller are connected with one another through a CAN (controller area network) bus. The electric control device is novel in design and reasonable in structure. Due to the fact that the two controllers in charge of a monitoring system and a hydraulic system respectively are used, fault during service occurs less easily. In addition, the gas engine controller is provided with the rotation speed sensor, current input of the proportional electromagnetic valve can be controlled accurately to change flow of a main pump, and accordingly work efficiency of the excavator is improved. The technical problem that the excavators are inconvenient to use and low in work efficiency in the prior art is solved.
Description
Technical fieldThe invention belongs to excavator electric control gear technical field, be specifically related to a kind of gas power hydraulic crawler excavator electric control gear.
Background technologyProblem about energy-saving and emission-reduction in the prior art is the theme of society always, and in order to reduce resource consumption, reduce to pollute, various new technologies, new product release one after another, solar telephone for example, electric bus, gas engine controller etc.; Under this background, the crawler hypraulic excavator of using gas engine controller arises at the historic moment, and this type of is based on the hydraulic crawler excavator electric-control system of the gas engine controller core of whole excavator especially, vital effect is being arranged aspect the efficiency of excavator improving.Tradition generally only adopts a medium controller based on the hydraulic crawler excavator of fuel engines, be responsible for simultaneously monitoring system, hydraulic system and with the communication of engine controller, but this control device easily makes mistakes in transmission course, design falls behind, use inconvenience, and inefficiency.
Summary of the inventionThe objective of the invention is to solve prior art and have use inconvenience and ineffective technical problem, provide a kind of gas power hydraulic crawler excavator electric control gear, to overcome the deficiencies in the prior art.
A kind of gas power hydraulic crawler excavator of the present invention electric control gear, its main points are that it comprises the HYDRAULIC CONTROL SYSTEM device that is connected with gas engine controller by the CAN bus and the monitoring system controller that is connected wire and is connected with display; Described gas engine controller is provided with the speed probe that is connected with the HYDRAULIC CONTROL SYSTEM device; Described speed probe is connected with proportion magnetic valve; Described monitoring system controller is connected with liquid level sensor; Described HYDRAULIC CONTROL SYSTEM device is connected with grip; Described monitoring system controller, HYDRAULIC CONTROL SYSTEM device and gas engine controller interconnect by the CAN bus respectively.
The present invention is novel in design, rational in infrastructure, owing to adopting two controllers, is responsible for respectively monitoring system and hydraulic system, is not easy in the course of work to make mistakes; Simultaneously, the speed probe that gas engine controller is provided with, the flow of the accurately input of control ratio electromagnetic valve current and then change main pump, thereby the operating efficiency of raising excavator.The invention solves prior art and use inconvenience and ineffective technical problem.
Description of drawingsAccompanying drawing is structural principle schematic diagram of the present invention.
Among the figure 1, monitoring system controller 2, HYDRAULIC CONTROL SYSTEM device 3, gas engine controller 4, liquid level sensor 5, display 6, grip 7, speed probe 8, electromagnetic proportional valve 9, CAN bus
The specific embodimentWith reference to the accompanying drawings, the present invention it comprise the HYDRAULIC CONTROL SYSTEM device 2 that is connected with gas engine controller 3 by CAN bus 9 and the monitoring system controller 1 that is connected wire and is connected with display 5; Described gas engine controller 3 is provided with the speed probe 7 that is connected with HYDRAULIC CONTROL SYSTEM device 2; Described speed probe 7 is connected with proportion magnetic valve 8; Described monitoring system controller 1 is connected with liquid level sensor 4; Described HYDRAULIC CONTROL SYSTEM device 2 is connected with grip 6; Described monitoring system controller 1, HYDRAULIC CONTROL SYSTEM device 2 and gas engine controller 3 interconnect by CAN bus 9 respectively.
Monitoring system controller 1 acquisition applications of the present invention is in the signal of the various sensors of excavator, before wherein having removed to the collection of fuel level signal, change the collection to gas content signal in the combustion gas gas cylinder into, gas quantity gathers by the LNG liquid level sensor 4 that is integrated in the LNG gas cylinder, then collection result is presented in the display 5 in the driver's cabin with the column form; HYDRAULIC CONTROL SYSTEM device 2 gathers the signal of grip 6, by CAN bus 9 and gas engine controller 3 controller communications, thus control gas engine controller rotating speed; Simultaneously, also additionally installed speed probe 7 additional at gas engine controller, can be more accurately input by closed-loop control proportion magnetic valve 8 electric currents, change the main pump flow, thereby raising efficiency of excavator, and controller also is responsible for the switching of three kinds of patterns of excavator, in order to be applicable to no operating mode; Carry out communication by CAN bus 9 between monitoring system controller 1, HYDRAULIC CONTROL SYSTEM device 2 and gas engine controller 3 threes, the mutual cooperation of three, design can this type of hydraulic crawler excavator operating efficiency based on gas engine controller of maximized raising like this, make the combustion gas excavator not only remarkably productive in energy-saving and emission-reduction, more have economy and practicality simultaneously.
