Description
Technical field
The present invention relates to the electric control operation technical field, relate in particular to a kind of electron linkage operation system for tower crane.
Background technology
The selected conventional joint action table of tower crane generally is to drive universal seclector or cam set switch by mechanical transmission component at present, realizes different switch closure order at different gears, to reach the purpose of control electrical control cubicles.But because the selected mechanism of different model tower machine difference, the selected mechanism of same type machine tower machine also is not quite similar, even if mechanism is identical, but because each manufacturer production is managed and the design concept difference, all these all can cause the electric control principle difference, thereby finally cause its joint action table number of switches different with closing order.The production control of forming a complete production network the merchant for tower machine host manufacturer and joint action table so, purchasing management, past-sale service bring many troubles.
On the other hand, because the electrical control cubicles system will insert various killers, the electrical control cubicles terminal row will give and stay the access terminal, causes the electrical control cubicles wiring loaded down with trivial details, and it is low to manufacture efficient, safeguards the debugging difficulty.
Simultaneously conventional joint action table itself can't solve and occur slipping the problem of hook owing to gear-change operation is not in place, can only set about from electric-control system if think head it off, must cause electric-control system huger, loaded down with trivial details (domestic 98% enterprise does not handle it to this at present) like this.
A kind of universal intelligent joint action table of research and development has crucial meaning under this prerequisite.Will further promote the integral level of China tower crane electrically controlled manipulation system along with the successful release of this product, better assist tower machine host manufacturer calmly in the face of the high-end market competition, for driving, the digitalisation of tower machine industry mechanism lays the foundation, on this product basis and then be extensible to fields such as running control system, development prospect is very wide.
Summary of the invention
The invention provides a kind of operating personal use, simplicity of design, tower crane electronic type linkage operation system safe in utilization be convenient to.
Electron linkage operation system for tower crane provided by the invention comprises control box, read-out and electrical control cubicles driver element, wherein said control box comprises left and right two control boxs that are separately positioned on driver's chair both sides in the operator's compartment, described read-out is arranged on the operator's compartment front end, and the electrical control cubicles driver element is installed in the electrical control cubicles.
Be provided with the gear position sensor that hoists in the wherein right control box, be provided with revolution, luffing gear position sensor and master control board in the left control box.
Preferably, be connected with limiting device on the electrical control cubicles driver element, the micro controller system on the electrical control cubicles driver element is handled limit signal, and sends spacing control command.
Further, left and right control box has bar handle respectively, described bar handle drives the gear position sensor rotation by mechanical device, sensor will send impulse singla when rotating and pass to the micro controller system of master control board, calculate handle place gear and rotation direction by micro controller system, send control command according to the spacing information of killer that gear and rotation direction and electrical control cubicles driver element collect, pass to the electrical control cubicles driver element, the thyristor that drives corresponding circuit disconnects or thereby closed control interchange contact disconnects or adhesive, realizes the control to mechanism speed and direction.
Further, this system also has zero-bit self-locking and automatic runback device, and locking press button is arranged on the bar handle.System allows the handle gear asynchronous with the gear of mechanism's reality of work.And the gear of system enters interval less than the interval of withdrawing from this gear.
Where no matter described handle be in, and necessarily is within a certain gear interval generation of situation out of supply when avoiding gear switch.When described handle stops less than in the time of 3 seconds at a certain gear, delay time and to carry out gear switch in 3 seconds.
Described read-out is used to show handle gear information, mechanism's real work gear information and spacing information, and there is auditory tone cues in system during gear switch.
Beneficial effect of the present invention is as follows:
1, where no matter the handle of electron linkage of the present invention system be in, necessarily be within a certain gear interval, the generation of situation out of supply when having avoided gear switch, and the gear of electron linkage operation system enters interval less than the interval of withdrawing from this gear, in the time of can effectively avoiding conventional joint action table to be in two gear critical spots like this, gear does not stop the problem switched.
2, realized that mechanism is by low speed gear shift delay function when high speed is switched.System controlled according to the time that handle stops on a gear, when handle stops less than in the time of 3 seconds at a certain gear, delay time and can carry out gear switch in 3 seconds, (delay time can be according to the customer requirement setting to replace the effect of time-delay head in the former electrical control cubicles, minimum is 0 second, is up to 9 seconds).
3, read-out shows the gear and the handle gear of living in of current mechanism work, and there is auditory tone cues in system during gear switch, has so just omitted the structure that conventional joint action table mechanical impact is reminded gear shift, and system is lighter, flexible, and it is better to handle feel.
4, limiting device inserts on the electrical control cubicles driver element of electron linkage operation system, and micro controller system is handled limit signal, and sends spacing control command, and all limiting device information show by read-out.
5, omitted the cable connection (electron linkage operation system have master control board signal wire (SW) to automatically controlled driver element) of conventional joint action table to electrical control cubicles.
6, select for use electron linkage operation system can greatly simplify the electrical control cubicles wiring, improve producer's electrical control cubicles make efficiency, shorten electrical control cubicles and organize the cycle.
But 7, setting code is as required determined useful life by manufacturer when dispatching from the factory, and expires must import password and can use.
8, the user can be provided with joint action table as required, selects the model (as: QTZ40-A, QTZ63, QTZ125) of corresponding type to confirm to get final product convenient production and storehouse management.
9, native system has zero-bit self-locking and automatic runback device, will guarantee by the locking press button on the lower handle during manipulation.
To sum up, the present invention is fully studying on the basis of tower crane electric-control system and mechanism operating system, in conjunction with the concrete characteristics of handling, is utilizing microelectronic technique, the information sensing technology, ICT is followed creative principle, market demand principle, user's priority principle, the high quality of new generation of independent research, performance-oriented tower crane electrically controlled manipulation system is the desirable electric system intelligent control center of tower crane.
