The system of above-mentioned restriction crane arm support work area, wherein, said operating terminal comprises keyboard and elevator joystick, said keyboard and said telltale become one.
The system of above-mentioned restriction crane arm support work area, wherein, said telltale is connected with said controller through CAN-bus.
The system of above-mentioned restriction crane arm support work area, wherein, said detector is connected with said controller.
A kind of hoisting crane comprises the jib and the anti-hypsokinesis oil cylinder of main platform, operator's compartment, band arm-tie, wherein; Comprise system like above-mentioned each described restriction crane arm support work area; Said angular transducer in the said detector is positioned on the said jib, and said oil pressure sensor is positioned on the said anti-hypsokinesis oil cylinder, and said pulling force sensor is contained on the said arm-tie; Said telltale is located in the said operator's compartment, and said controller is located in the electrical control cubicles on the said main platform.
The utility model can improve the safety of crawler crane under the special operation environment, reduces operator's labour intensity, and the work area restriction is provided with the interface and adopts animation mode, and the interface is simple, directly perceived, and the setting area boundary value is convenient, workable.
Description of drawings
Fig. 1 is the structural representation block diagram of the system of the utility model restriction crane arm support work area.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further, but not as the qualification of the utility model.
Please referring to shown in Figure 1; The system of the utility model restriction crane arm support work area wherein, comprises controller 1; Telltale 2 and detector 3; Detector 3, telltale 2 are connected with controller 1 respectively, and detector 3 comprises pulling force sensor 31, oil pressure sensor 32 and angular transducer 33, and controller 1 is connected with the winch 5 of hoisting crane.Native system also comprises an operating terminal 4, and operating terminal 4 is connected with controller 1, and operating terminal 4 comprises input keyboard 41 and elevator joystick 42, and keyboard 41 becomes one with telltale 2, and said system promptly constitutes a jib work area restriction system.
Native system is collected jibs through the detector in the restriction system of above-mentioned jib work area 3 information such as operating mode combination, angular dimension are confirmed the position of jib.Particularly; In interior telltale 2, design the demarcation page at integrated keyboard 41; Detector 3 is collected information real-time such as the operating mode combination, angular dimension of jibs and is transferred to controller 1, and via controller 1 is handled the back and on telltale 2, shown the jib current location in real time, then the zone of limiting jib work of upper change point and the lower-limit point through the work of setting jib; Can send instruction to the winch 5 of hoisting crane so jib arrives restricted areas range boundary our controller 1, limit the action of jib.Wherein, upper change point and lower-limit point can also can place the restricted areas boundary point also manually to demarcate through input keyboard 41 jib through elevator joystick 42 and import through input keyboard 41 manually direct input values.
Further, telltale 2 is connected with controller through CAN-bus respectively with elevator joystick 42 in the operating terminal 4.CAN-bus (Controller Area Network) is a controller local area network; Be one of most widely used fieldbus in the world, it is a kind of serial communication bus of many master modes, and basic design regulation requires to have higher bit rate; High noise immunity; And can detect any mistake of generation, when signal transmission distance reaches 10Km, the data transmission rate up to 5Kbps can be provided still.
The invention also discloses a kind of above-mentioned each crane structure of system of restriction crane arm support work area that comprises; The jib and the anti-hypsokinesis oil cylinder that comprise main platform, operator's compartment, band arm-tie; Angular transducer 33 in the detector 3 is positioned on the jib, and oil pressure sensor 32 is positioned on the anti-hypsokinesis oil cylinder, and pulling force sensor 31 is contained on the arm-tie; Telltale 2 is located in the operator's compartment, and controller 1 is located in the electrical control cubicles on the main platform.Because the system and the prior art of this hoisting crane restriction crane arm support work area are distinct; Other parts are not drawn; Those skilled in the art can combine prior art to grasp the structure of other parts of hoisting crane that adopt the system that comprises above-mentioned restriction crane arm support work area, also will not give unnecessary details at this.
The above is merely the utility model preferred embodiment; Be not thus the restriction the utility model claim; So the equivalent structure that all utilization the utility model specification sheetss and diagramatic content have been done changes, and all is included in the protection domain of the utility model.
