Abstract
The utility model provides a hydraulic shovel miscellaneous function control system, its characterized in that: including the display, the display links to each other with the controller, relief valve, the supplementary equal connection director of solenoid valve, and control switch links to each other with the controller input end, be equipped with the soft control switch of supplementary solenoid valve in the display. When hydraulic shovel need change the operation device, at first press the soft control switch button of assisting the solenoid valve in the interface in the display, a relief valve port output high level signal will be carried out to the simultaneous control ware, reaches the deadweight safety valve and opens, presses control switch again, and supplementary solenoid valve got electricly and moved this moment, just can change the operation device. The device provided by the utility model having overcome the not enough of prior art, safe rationally having controlled and change or installation hydraulic pressure operation device, the user can not be because of there being the maloperation to result in the potential safety hazard, especially when the night operation, has guaranteed hydraulic shovel's operation security, reliability, convenience.
Description
Technical field
The utility model relates to the control of hydraulic crawler excavator, particularly relates to a kind of hydraulic crawler excavator Auxiliary Functions Control System.
Background technology
Excavator is a kind of excavation and the Engineering Work machine of shipment, in the infrastructures such as city, traffic, water conservancy, mine, river course, is called as " high-efficiency multi-function machinery ", has construction maneuverability, the advantage such as efficient.In order to adapt to various job status, excavator needs install or change different apparatus for work.In prior art, excavator is installed or changed apparatus for work is all by manually judging, sometimes because maloperation causes potential safety hazard.
Therefore, the utility model proposes a kind of safer rational electrohydraulic control system, safely and reasonably control to change or hydraulic work device is installed, to solve the security hidden trouble of hydraulic crawler excavator when changing apparatus for work.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of hydraulic crawler excavator Auxiliary Functions Control System that safely and reasonably can control to change or install hydraulic work device.
In order to solve the problems of the technologies described above, the technical solution of the utility model is to provide a kind of hydraulic crawler excavator Auxiliary Functions Control System, and it is characterized in that: comprise display, display is connected with controller, the equal connection control device of safety valve, pilot solenoid valve, gauge tap is connected with controller input; The soft gauge tap of pilot solenoid valve is provided with in display.
Preferably, when only having the soft gauge tap of described gauge tap and pilot solenoid valve to close, pilot solenoid valve output eloquence exports high level simultaneously.
Preferably, described display is connected by CAN with between controller.
The operating principle of hydraulic crawler excavator Auxiliary Functions Control System is as follows: when hydraulic crawler excavator needs to carry out replacing apparatus for work, first the soft gauge tap button of pilot solenoid valve will be pressed in interface in the display, represent and now can only carry out apparatus for work function, other actions are all invalid, safety valve port to be performed with Time Controller and export a high level signal, and deadweight safety valve is opened, otherwise replacing apparatus for work cannot be carried out.After the soft gauge tap of pilot solenoid valve and safety valve are opened, also need to press gauge tap, now whole electric control circuit is only closed-loop path, after controller receives this signal, pilot solenoid valve output port one high level signal will be performed, now pilot solenoid valve must be electric, and electromagnetic valve action, just can carry out replacing apparatus for work.
The device that the utility model provides overcomes the deficiencies in the prior art, can safely and reasonably control to change or hydraulic work device is installed, user can not cause potential safety hazard because of having maloperation, especially when operation at night, ensure that the operational security of hydraulic crawler excavator, reliability, convenience.
Accompanying drawing explanation
The hydraulic crawler excavator Auxiliary Functions Control System structured flowchart that Fig. 1 provides for the present embodiment.
Detailed description of the invention
For making the utility model become apparent, hereby with a preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
The hydraulic crawler excavator Auxiliary Functions Control System structured flowchart that Fig. 1 provides for the present embodiment, described hydraulic crawler excavator Auxiliary Functions Control System is made up of display 1, CAN 2, controller 3, safety valve 4, pilot solenoid valve 5, gauge tap 6 and hydraulic pressure, the electric components such as corresponding pilot valves and respective line.Display 1, controller 3, gauge tap 6, safety valve 4, pilot solenoid valve 5, pilot-actuated valve group are connected in electro-hydraulic circuit together, and composition electrohydraulic control system, meets the needs of different operating mode in real work
Be connected by CAN between display 1 with controller 3, safety valve 4, pilot solenoid valve 5 be connection control device 3 all, the soft gauge tap of pilot solenoid valve 5 is provided with in display 1, peripheral gauge tap 6 is connected with controller 3 input, only have two switches (the soft gauge tap of pilot solenoid valve 5 and peripheral gauge tap 6) to close simultaneously, pilot solenoid valve 5 output eloquence has high level output, and corresponding miscellaneous function just effectively (as the equipment such as destroyer, hydraulic shear).
The operating principle of the hydraulic crawler excavator Auxiliary Functions Control System that the present embodiment provides is as follows: when hydraulic crawler excavator needs to carry out replacing apparatus for work, first the soft gauge tap button of pilot solenoid valve 5 will be pressed in the interface in display 1, represent and now can only carry out apparatus for work function, other actions are all invalid, safety valve 4 port to be performed with Time Controller 3 and export a high level signal, and deadweight safety valve is opened, otherwise replacing apparatus for work cannot be carried out.After the soft gauge tap of pilot solenoid valve 5 and safety valve 4 are opened, also need to press gauge tap 6, now whole electric control circuit is only closed-loop path, after controller 3 receives this signal, pilot solenoid valve 5 output port one high level signal will be performed, now pilot solenoid valve 5 must be electric, and electromagnetic valve action, just can carry out replacing apparatus for work.
It is all small area analysis signal in whole circuit, and it is safe and reliable, key be need when changing apparatus for work display interfaces Sofe Switch and peripheral control switch 6 simultaneously closed and safety valve 4 output port be high level just effectively, user can not cause potential safety hazard because of having maloperation.Particularly when operation at night, conveniently, safely, reliably.
The hydraulic crawler excavator Auxiliary Functions Control System that the present embodiment provides, except for except hydraulic crawler excavator, also can be used for other engineering machinery, device as similar in loader, building machinery, load-carrying vehicle etc.
