As preferably,The pulling force sensor parts of overload protection type intelligence strand grinding machine are strain chip pulling force sensors.
As preferably,The display measurement parts of overload protection type intelligence strand grinding machine are comprised of micro controller system and liquid crystal display, and micro controller system gathers electric signal with the pulling force sensor parts by AD and is converted into numerical information and is presented on liquid crystal display.
As preferably,The power devices parts of overload protection type intelligence strand grinding machine are realized electronic startup to the power supply of the moving strand of electric motor starter grinding machine body, and after starting, the moving strand of electric motor starter grinding machine body charges to the power devices parts.
The utility model principle of work is as follows:
Overload protection type intelligence strand grinding machine pulling force overload protection device is connected between overload protection type intelligence strand grinding machine and ground anchor.Obtain the ground anchor pulling force size of tractor equipment according to measurement numerical value.Utilize the equilibrium of forces principle, the draught line pulling force equals frictional ground force and ground anchor pulling force sum.Relatively the anchor pulling force is very little due to frictional ground force, can ignore.The draught line pulling force is approximately equal to ground anchor pulling force.Measure ground anchor pulling force and obtain draught line pulling force numerical value.
In addition, adopt driving engine its starter motor after startup with electronic startup can generate electricity to the power supply charging that connects.
In sum: the beneficial effects of the utility model are:
1, therefore can obtain the draught line pulling force according to measuring numerical value, select maneuvering milling machine to select gear according to the draught line pulling force, realize the optimization of power output and speed, improve the loss of efficiency oil consumption.
2, when measuring numerical value over setting value, automatically shut down electric switch, protection draught line and maneuvering milling machine.
3, realize an electronic startup of key, start easy; Realize self-charging, make equipment continuous running work for a long time.
Solved present maneuvering milling machine draught line tension measurement and shown, the automatic overload protection of draught line pulling force, maneuvering milling machine safety arrestment, brake response speed are quick, maneuvering milling machine simple start, the long-term open-air problems such as power supply of using of equipment.
