Abstract
The utility model relates to a safety controlling device for a traveling hoist, comprising a main circuit and a control circuit. The main circuit comprises a motor, a switching element, a speed regulation resistor, etc. The control circuit comprises a safety power source, a control switch group, an output template, an input template, and a single chip computer. The interior of the operation room of the traveling hoist only has direct current safety voltage, and accordingly, the accidents that the operator is shocked through electric, etc. can not occur. The utility model has the characteristics of reasonable structure, safety, etc.
Description
The utility model relates to a kind of day truck control device, particularly the automatic control setup of safety.
The control setup of the overhead traveling crane that people use always (hoisting crane) generally is made up of power circuit and control circuit, and power circuit is made up of motor, speed adjusting resistance and on-off element, and on-off element is contactless switch or silicon control etc.Control circuit is made up of relay and switches set etc., and switches set is master controller or button etc.Owing to alternating current need be introduced operator's compartment,, as meeting accident the electric leakage accident, will jeopardize the life of staff in the operator's compartment in the operator's compartment as the control circuit power supply.
The utility model purpose provides a kind of overhead traveling crane safety control, makes to prevent electric shock accidents by the interior work safety of operator's compartment, solves the problems referred to above that prior art exists.
Goal of the invention of the present utility model realizes by following technical proposal:
Form control circuit by safety direct supply, singlechip CPU, input template, input template and master cock group etc., power circuit is made up of motor, on-off element and speed adjusting resistance etc.During use, by opening or closure of switches set, signals such as the just commentaries on classics of sky vehicle motor, counter-rotating, speed change are sent into singlechip CPU by input template carry out logical process, result by bus unit to output template, the output electric signal drives the on-off element conducting of power circuit, makes the overhead traveling crane machine operation.
Owing in the operator's compartment safe vdc is only arranged, remove the master cock group and be placed in the operator's compartment, remainder all places outdoor.Ensured the life security of operating personal like this, prevented that electric shock accidents from taking place.
The utlity model has characteristics such as rational in infrastructure, safe and reliable.
Fig. 1: be the utility model embodiment control circuit device schematic diagram.Fig. 2 is the utility model embodiment power circuit electrical schematic.
Below in conjunction with accompanying drawing, further specify the utility model by embodiment.
With reference to accompanying drawing 1: the control circuit of overhead traveling crane safety control is formed and is comprised direct current safety power supply PS, two 8 passage DC24V input template DI1 and DI2, singlechip CPU, three 4 * 220V output template DO1 and DO2 and DO3, switches set K etc.With reference to accompanying drawing 2, power circuit comprises the transwitch element W of motor I D, transwitch element KS-4, speed adjusting resistance R and convert resistance etc.
In an embodiment, switches set K is a master controller, place in the overhead traveling crane operator's compartment, and the 24V direct current (DC) that its operating voltage provides for direct current safety power supply PS, thus guaranteed the life security of operating personal.Instructions such as the just commentaries on classics of overhead traveling crane, counter-rotating, speed change are sent into input template DI1 and DI2 by switches set K, and entering single piece plate CPU by the unit bus carries out logical process, and result is sent into output template DO1-3 by the unit bus.Output template can be connected corresponding known relay, triggers transwitch element conductive in the corresponding power circuit by relay tip, just finish change, instruction such as counter-rotating, speed change.Also can directly trigger silicon control conducting in the power circuit with the output template output signal.Also can replace master controller to constitute switches set with conventional push button.Owing to adopt micro controller system to carry out logical process, can make the overhead traveling crane safe and reliable operation, degree of automation improves, and has made things convenient for maintenance.
