The utility model has the advantages that the design is reasonable, the use is safe and reliable, the circuit is simple, the property is stable, the control is accurate, the maintenance and the failure treatment are convenient, different working methods can be provided, and a plurality of dried oil pumps can be controlled to operate at the same time, so that the device is applied to control the lubrication of the excavator.
Description
Technical field
The utility model relates to a kind of control device, and the excavator of a kind of PLC of employing that says so more specifically lubricates control device.
Background technology
At present, used a large amount of auxiliary reclays, the time relay in traditional relay control system, the quantity of its contact and wiring is more, occurs following problem easily: 1, the space accounting is big, the energy consumption height; 2, numerous and diverse design, installation, debugging work load; 3, loose contact, misoperation easily, reliability is low; 4, the workload of inspection and maintenance is big.Along with applying of programmable logic controller (PLC), PLC widely applies in various device, and the using PLC technology is controlled the lubricating system of excavator accurately, is to guarantee that excavator is stable, an important step of efficient operation.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of reasonable in design, safe and reliable, stable performance, the lubricated control device of excavator of employing PLC.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals: comprise programmable logic controller PLC, keyboard, graphic terminal display, input signal, warning device, auxiliary reclay, dry oil pump electromagnetic valve, described keyboard is connected on the graphic terminal display, the graphic terminal display links to each other with programmable logic controller PLC, the input of the output auxiliary reclay of programmable logic controller PLC, the output of auxiliary reclay link to each other with the dry oil pump electromagnetic valve with warning device respectively.
Because adopt technique scheme, the beneficial effects of the utility model are: reasonable in design, with a programmable logic controller PLC electromagnetic valve and other auxiliary equipment are controlled, satisfy the lubricated operating mode demand of excavator; Strong interference immunity, the lubricating system control signal is controlled by the PLC programmable logic controller, and the speed of service is fast, reliability is high; Circuit is simple, adopts PLC to replace a large amount of relays, has reduced outside cabling; Performance is good, and fault rate is low, production efficiency is high, energy-saving effect is obvious, noise is low, easy to maintenance.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the utility model comprises programmable logic controller PLC, keyboard, graphic terminal display, input signal, warning device, auxiliary reclay, dry oil pump electromagnetic valve, described keyboard is connected on the graphic terminal display, the graphic terminal display links to each other with programmable logic controller PLC, the input of the output auxiliary reclay of programmable logic controller PLC, the output of auxiliary reclay link to each other with the dry oil pump electromagnetic valve with warning device respectively
Operating principle of the present utility model is: connect power supply PLC and get electric work, control signal is through PLC, provides working method and instructs corresponding solenoid valve, thereby finish lubricated work.When petrol starvation occurring, auxiliary reclay control warning device is reported to the police.
The utility model is equipped with the graphic terminal display, by with being connected of PLC, can make amendment to some parameters of PLC inside by the keyboard that is connected with the graphic terminal display, the graphic terminal display also can be monitored some parameters of PLC inside.Lubrication interval parameter in the PLC internal processes can be by directly being provided with on the graphic terminal display, and do not need behind the power-off restarting to reset.
