Description

Crawler crane bar handle function change-over device

One, affiliated technical field

The utility model relates to a kind of crawler crane maneuver control device, the particularly control setup that handle function is switched.

Two, background technology

The crawler crane that uses electric control handle to handle, control action comprises major and minor volume lifting, major and minor luffing lifting about revolution, has surpassed luffing etc.About these actions all are defined on two handles.So handle must be multiplexing in control process.

In order to satisfy the control of handle, handle is switched above-mentioned many actions.Common practices be with the input port of handle bonded assembly controller on insert the change-over switch of suitable number, to coding of controls, on off state is judged by controller, switch handle function, realize the corresponding relation of handle and above-mentioned action.

Though more than this traditional approach directly perceived, have wretched insufficiency:

1, very flexible need be built external circuit, and the function ratio is difficulty.

2, take controller the I/O port, cause the wasting of resources.

3, hardware switch has self life-span, easily produces the phenomenon of bad contact in long-term use, and reliability is low.

Three, summary of the invention

The purpose of this utility model provides a kind of convenient, flexible, reliability is high, cost is low crawler crane bar handle function change-over device.

The technical solution adopted in the utility model is: crawler crane bar handle function change-over device comprises left and right sides electric control handle, controller and man-machine interface, the three is interconnected by circuit, man-machine interface of the present utility model is a touch-screen display, and left and right sides electric control handle, controller and man-machine interface are interconnected by the CAN bus; Several touch key-press are set in touch-screen, with different letters or figure button is named definition, button on touch-screen is touched on time, corresponding handle function is selected, and this button can self reset, and also can be resetted by other function buttons, key information sends to controller by the CAN bus, by controller information is confirmed, and controlled selected action, realize the selection and the switching of action.

The utlity model has following beneficial effect:

1, left and right sides electric control handle, touch-screen display and controller pass through the total wire joint of CAN, easy-to-connect, and favorable expandability, the reliability height, system more optimizes, and is more stable;

2, it is flexible that man-machine interface realizes pressing key control, and programming is simple, and is easy to operate, visual in image.

3, the mode of handle can be realized that alerting ability is strong by program arbitrarily.
