These three kinds of functions of the equipments are single, can not carry out comprehensive protection to hoisting crane.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide a kind of multi-functional weight control that can carry out comprehensive multifunction protection to hoisting crane simultaneously, to overcome above-mentioned deficiency.
To achieve these goals, the utility model opto-electronic pickup, bearing seat formula weighing sensor, height under hook sensor coder and center processor constitute, be characterized in: opto-electronic pickup is installed in the hoisting crane both sides, be installed on the corresponding reflecting plate of opto-electronic pickup in addition and face hoisting crane one side mutually, bearing seat formula weighing sensor is contained in crane hoisting drum one end, height under hook sensor coder is contained in drum shaft one end, be contained on the same axle with bearing seat formula weighing sensor, the switching value signal of opto-electronic pickup output links to each other with the center processor data line, the output of bearing seat formula weighing sensor is joined with the center processor data line behind amplifier, and the output of height under hook sensor coder is connected with the center processor data line behind amplifier.
Above-mentioned center processor panel is provided with that the LED weighing shows and signal lamp, and the LED height under hook shows and signal lamp that there is the adjacent hoisting crane spacing alert lamp with the right side in hoisting crane left side the panel both sides, is provided with various setting input keyboards below the panel.
The utility model integrates the three kinds of defencive functions of anticollision between overload crane demonstration and control, the demonstration of crane hook height and control, the hoisting crane; with a control instrument cabinet; satisfy little, the compact conformation of volume, conveniently install at crane cab.The control path of three kinds of defencive functions is combined among the control system of a micro controller system, give full play to the controllable function of micro controller system, line design is more simple and reliable, and control is convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a functional block diagram of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model opto-electronic pickup GD1, GD2 are installed in the hoisting crane both sides, and reflecting plate 1,2 is installed on and faces hoisting crane one side mutually, and when distance between two hoisting cranes during less than the alarming value set, sensor sends the switching value signal and delivers to center processor MCU; Be contained in the bearing seat formula weighing sensor CZ1 of crane hoisting drum one end 3 or be contained in the bearing seat formula weighing sensor CZ2 of another winding drum one end 4, convert weight signal to be directly proportional electric signal, behind amplifier A1, send into center processor MCU with weight; Be contained in drum shaft one end, be contained in height under hook sensor coder BM on the same axle, the height under hook signal is converted to the electric signal of its direct ratio behind amplifier A2, send into center processor MCU with the bearing seat sensor.
The utility model center processor MCU is made up of distance detecting between weighing detection, height under hook detection, the crane and four parts of multi-functional lifting control instrument.Its principle of work is: act on weight signal P1, P2 on the weighing sensor, through weighing sensor CZ1, CZ2, convert the electric signal addition that is directly proportional with weight signal to after amplifier A1 amplifies; If have only the signal of a weighing sensor just directly to send into amplifier A1, send into the voltage to frequency converter V/F1 among the center processor MCU after the amplification, send into interface module JK again;
Height under hook L converts the electric signal that is directly proportional with height under hook L to through height sensor BM, sends into the voltage to frequency converter V/F2 among the center processor MCU after amplifier A2 amplifies, and sends into interface module JK again.Data among the interface module JK are that singlechip CPU reads.
Between the hoisting crane apart from S1, S2, convert to through opto-electronic pickup GD1, GD2 and to report to the police and the switching value signal of control, send into photoisolator GE1, the GE2 among the center processor MCU after, send among the CPU again.
After distance detecting signal CPU in center processor MCU handles between weighing detection signal, height under hook detection signal, the hoisting crane, export four LED weight shows signal CLXS1, export four LED height shows signal GDXS2, the output sound and light alarm shows SG, output relay control signal KZ.The input of system's initial value design, self-test signal is sent into CPU by the keyboard JP of center processor MCU panel.
With these three kinds of detection signals, after conversion, send into simultaneously in the micro controller system of center processor MCU and handle, export demonstration, warning and control signal then.Given full play to the controllable function of micro controller system, made the control setup volume littler, compact conformation, reliable operation is conveniently installed in the crane operator chamber.
The content that is not described in detail in this specification sheets belongs to this area professional and technical personnel's known prior art.
