Abstract
The invention discloses an electric control system of an electric hoist. The electric control system of the electric hoist comprises a control handle, a control circuit board, a capacitor and a motor. The control handle is provided with a control switch. The control switch and the capacitor are both eclectically connected with the control circuit board. The control switch controls operation of the motor through the control circuit board. The electric control system of the electric hoist is characterized in that a low voltage controller for converting high voltage into low voltage is arranged on the control circuit board, operation high voltage is input to the motor, and safe low voltage is input to the control switch on the control handle. The input 220V/110V high voltage is converted into the 24V low voltage through the low voltage controller, i.e., the motor still uses the high voltage, but the safe low voltage is input to the control switch on the control handle, and therefore potential safety hazards of the control handle in the background technology are eliminated.
Description
Technical field
The present invention relates to the improvement invention of a kind of electric-control system, particularly to be the electric-control system of electric block.
Background technology
Electric block controls motor starting by handle, and the output voltage of power supply is generally 220V or 110V, and therefore the switch on joystick is all directly connected to high pressure, and potential safety hazard is very big；Additionally, capacitor value needed for the startup of motor is big, capacitor value needed for Yun Hanging is the least, the motor of existing electric block all uses a large capacitor device, and the electric energy of the biggest consumption of capacitor value is the biggest, it is big that the motor feels hot, quick heating, working time is short, therefore cannot realize the continuous use of motor.
Summary of the invention
The technical problem existed in view of background technology, the technical problem to be solved in the present invention is to provide a kind of electric-control system using safety, power consumption be little, supply variation can use time big continuously electric block.
In order to solve above-mentioned technical problem, the present invention adopts the following technical scheme that and realizes: the electric-control system of this kind of electric block, include joystick, control circuit board, capacitor and motor, control switch it is provided with on described joystick, described control switchs, capacitor all electrically connects with control circuit board, the described switch that controls controls motor operation by control circuit board, it is characterized in that on described control circuit board, being provided with the low pressure controller that high pressure is converted into low pressure, described motor accesses and runs high voltage, control switch on described joystick accesses safety low-voltage.
Described control switch includes upstream switch, downing switch and emergency stop switch.
Described control circuit board connects electrical switch, described capacitor includes start-up capacitance device and working capacitor, described electrical switch electrically connects with start-up capacitance device and working capacitor respectively, when motor starting operating mode, described start-up capacitance device and working capacitor are concurrently accessed participation electric motor starting, after described motor operation, described start-up capacitance device exits motor rotation circuit.
The 220V/110V high pressure of access is converted into 24V low-voltage, i.e. motor by low pressure controller and still uses high pressure by the present invention, and the control switch on joystick then accesses safety low-voltage, so eliminates the potential safety hazard that in background technology, joystick exists；The present invention also uses two capacitors to be connected with motor, and control being switched in or out of two capacitors when different operating mode by electrical switch, the most more reasonably make electricity container, reduce electric energy loss, reduce the heat that motor operationally produces, extend its use time, thus realize the continuous use of motor.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Further describe the operation principle of the present invention and relevant details thereof below in conjunction with the accompanying drawings.
Referring to the drawings, the electric-control system of this kind of electric block, include joystick, control circuit board, capacitor and motor, control switch it is provided with on described joystick, described control switch includes upstream switch, downing switch and emergency stop switch, described capacitor includes start-up capacitance device and working capacitor, it is provided with on described control circuit board and high pressure is converted into the low pressure controller of low pressure, electrical switch and relay controller, low pressure controller of the present invention, for high pressure is converted into low pressure, comprises all other controllers with this function；The described switch that controls electrically connects with low pressure controller, the voltage so controlling switch access is safety low-voltage, described motor is connected with high voltage power supply by relay controller, the voltage of 220V or 110V can be converted into 24V voltage by low pressure controller according to demand, 24V low tension belongs to safe voltage, will not damage human body, therefore the use of joystick is safer；Described upstream switch, by the first Control, makes motor up, and downing switch passes through the second Control, makes motor descending.Described electrical switch electrically connects with start-up capacitance device and working capacitor respectively, and when motor starting operating mode, described start-up capacitance device and working capacitor are concurrently accessed participation electric motor starting, and after described motor operation, described start-up capacitance device exits motor rotation circuit.I.e. control two capacitors when different operating mode by electrical switch to start, the capacitor value required when motor starting is big, now start-up capacitance device and working capacitor start simultaneously, produce bulky capacitor value for motor, capacitor value required after running after motor starting is less, now a capacitor just can feed motor use, therefore start-up capacitance device is disconnected, the most more reasonably make electricity container, reduce electric energy loss, reduce the heat that motor operationally produces, extend its use time, thus realize the continuous use of motor.
