Abstract
The invention discloses a control device and a method for improving a working efficiency of a hydraulic excavator. The control device comprises an ECU connected with a standard database, wherein the ECU is respectively connected with an electric control device for acquiring signals and a main pump electro-hydraulic proportional valve for finely adjusting a power of a main pump; the electric control device is respectively connected with a multi-way valve, pilot oil and the main pump of the hydraulic excavator; and the main pump electro-hydraulic proportional valve is connected with the main pump. The control method specifically comprises the following steps: firstly, the electric control device acquires the signals; and then, the ECU compares the signals acquired by the electric control device with standard data, and controls the main pump electro-hydraulic proportional valve to finely adjust the power of the main pump so as to adjust an action of the excavator to be accordant with a standard operation mode. The control device and the control method prevent the problem of low working efficiency of the excavator caused by different operation habits of drivers, reduce the energy loss, improve the working efficiency of the excavator, and improve the controllability of the excavator.
Description
Technical field
The present invention relates to a kind of control device and the method that improve hydraulic crawler excavator operating efficiency, belong to hydraulic crawler excavator technical field.
Background technology
A kind of general machinery equipment that hydraulic crawler excavator is is predominant use with earth excavation, the cubic meter of stone, it is the most widely used important engineering machinery in building, be generally used in the engineerings such as mining, water conservancy construction, road construction, urban renewal, to saving manpower, boost productivity and there is very important effect.Along with the development of hydraulic crawler excavator control technology, energy-efficient, the intelligent trend having become excavator development.
Hydraulic crawler excavator realizes action by the excavator driving person of specialty by manipulation joystick to carry out work.But because the working experience of excavator driving person and operating habit have very large difference, result in excavator under identical operating mode, the efficiency of work is inconsistent, makes excavator operating efficiency low, cause certain wasting of resources.In order to reduce the energy loss because operator's difference causes, promote the operating efficiency of excavator, improve the handling of excavator, it is very necessary for addressing this problem.
Summary of the invention
The technical problem to be solved in the present invention causes excavator operating efficiency low because hydraulic crawler excavator driver's operation custom is different, thus cause energy loss.
In order to solve the problems of the technologies described above, technical scheme of the present invention is to provide a kind of control device improving hydraulic crawler excavator operating efficiency, it is characterized in that, comprise the ECU be connected with normal operating data storehouse, ECU respectively with for collection signal electric control gear, be connected for the main pump electro-hydraulic proportional valve of finely tuning main pump power; Electric control gear is connected with the banked direction control valves of hydraulic crawler excavator, guide oil, main pump respectively; Main pump electro-hydraulic proportional valve is connected with main pump.
Present invention also offers a kind of control method improving hydraulic crawler excavator operating efficiency, it is characterized in that, adopt the control device of above-mentioned raising hydraulic crawler excavator operating efficiency, pressure and the flow signal of hydraulic crawler excavator main pump, banked direction control valves and guide oil is first gathered by electric control gear, then after the normal data of the operate in standard mode preset in the signal of electric control gear collection and normal operating data storehouse contrasts by ECU, ECU controls the power of main pump electro-hydraulic proportional valve fine setting main pump again, thus the action of adjustment excavator, make it consistent with operate in standard mode.
The invention provides a kind of intelligent controlling device, avoid because driver's operation custom is different and cause the problem that excavator operating efficiency is low, reducing energy loss, improve the operating efficiency of excavator, that improves excavator can be handling.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram improving the control device loop of hydraulic crawler excavator operating efficiency provided by the invention.
Detailed description of the invention
For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
