Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Figure 1-3, the S. A. position fixing system of hoisting crane of the present utility model, described hoisting crane comprises support rail beam, cart and dolly, described cart and dolly comprise locating module respectively, for cart, described locating module comprises power supply, function opening switch, the station detecting unit U3 of cart and work station point distance can be monitored, the treater U4 be connected with described station detecting unit communication, as PLC, its logic control different according to the input and output of station detecting unit, and the slew relay K2 that be connected controlled with described treater U4 and deceleration relay K3 respectively, a pair normally closed contact K2-1 of described slew relay is arranged in series in cart advance command signal line, a pair normally closed contact k3-1 of deceleration relay is arranged in series on cart very fast instruction signal wire (SW), described advancement commands is cart left lateral or right lateral instruction, namely near the direction of work station point, described very fast instruction is the very fast instruction of cart.The locating module of dolly is same as described above, and wherein the advancement commands of dolly means the advance of dolly or retrogressing equally, that is, dolly from a upper station near the direction of this work station point.
Wherein, described station detecting unit comprises position sensing unit, be arranged on deceleration trigger that the run trace of described cart or dolly can be interfered with described position sensing unit and stop trigger, described stopping trigger being arranged on work station point center, described deceleration trigger is arranged on the anterior preset distance of cart or the work station point of dolly near direction, if namely cart is close on the left of work station point, namely so deceleration trigger is arranged on preset distance on the left of work station point, wherein, described deceleration trigger and the trigger that stops are separately positioned on support rail beam with on cart.
After work station point positioning function is opened, hoisting crane will stop at work station point automatically in operation.Human users's crane is through deceleration trigger, very fast instruction is disconnected, and cart runs and becomes slow running from running fast, reaches when stopping trigger (center position of aiming station point), advancement commands is disconnected, and cart stops at this.Human users's trolley travelling, when being positioned at dolly through deceleration trigger, trolley travelling becomes slow running from running fast, and reach when stopping trigger (center position of aiming station point A), dolly stops at this.
Specifically, described position sensing unit is the cross limit switch or the laser sensor with two-way output or two position transdusers that are arranged on cart or dolly.Certainly, also can select to arrange a trigger on dolly or cart, and described position sensing unit is arranged on track, can the purpose of this utility model be realized equally.Specifically, the cross limit switch (as Italian G.G brand and model FCR006) of machinery, just turning 90 degrees output switching value, positive turnback exports a switching value.Stirring limit switch state through two-stage reversion when 180 degree is 0.For dolly, when it runs into pin 5, pin is stirred cross limit switch 4 and has been carried out 90 degree of rotations, the S2 contact action of cross limit switch inside.When running into pin 6, cross is spacing has carried out again 90 degree of rotations under the stirring of pin, and now cross is rotated to 90 degree, the inner S1 contact also corresponding triggering of cross limit switch.When overhead traveling crane is from aiming station point reverse direction operation, pin 5,6 makes the spacing opposite spin of cross, and after overhead traveling crane leaves station, the spacing state of cross transfers normality to.For cart, be then cross limit switch 1 and the coordinating of pin 2,3.
Further, can be handling for improving, the hand behaviour end of described hoisting crane is provided with positioning function key, the output command that positioning function key is corresponding is provided with function relay, a pair open contact of described function relay is arranged in locating module as function opening switch, meanwhile, also comprise and being communicated with and the unit H1 that warns controlled by described function opening switch with described power supply, as indicator lamp etc.Positioning function key is crane control unit, as a part for pocket torch door, as positioning function key can be one can the button of self-locking.
Automatically stop concrete Systematical control to explain in detail for cart locating point as follows: wherein, the positioning function of cart is similar with the positioning function of dolly, again no longer launches, both can open simultaneously or only open one.
1. when needing this function
One, press and press positioning function key, namely start navigation button make its self-locking, positioning function opening warn lamp works, and when prompting user of service hoisting crane runs to aiming station, the control system of S. A. location is opened.
Now K1 relay coil adhesive, K1 open contact closes.Control power supply L to be powered to lower end by station detecting unit U3.
Two, the instruction that cart runs performance element U2 reception cart operation control command unit U1 makes cart run to aiming station point, be arranged in station detecting unit U3 on cart first through the pin 2 of Fig. 2, switch S 2 action of station detecting unit U3 inside, and state is transferred to treater U4, by treater, as the conversion of PLC technology internal logic, it is electric that treater U4 output makes the coil of relay K 3 obtain.Relay K 3 normally closed contact K3-1 becomes open-circuit condition, and the fast signal that crane runs performance element disconnects, and hoisting crane starts to become slow running.Continue manipulating crane cart to run to aiming station, the pin 3 of station detecting unit U3 again in Fig. 2, switch S 1 action of treater U3 inside, and state is transferred to treater U4, by treater as the conversion of PLC technology internal logic, treater U4 unit exports and makes relay K 2 coil obtain electric, the normally closed contact K2-1 of relay K 2 becomes open-circuit condition, the slow speed signal that crane runs performance element U2 also disconnects, hoisting crane stops at this, achieves work station point and automatically stops.
Three. when hoisting crane is in aiming station point, operator controls cart inverted running, and the inverted running instruction of hoisting crane performance element is connected, and hoisting crane inverted running, station detecting unit U3 after 2,3 driving levers, returns to normality successively.
Four. when hoisting crane is in aiming station, operator wants to continue to run along this direction, presses positioning function key, namely start navigation button, make push-button reset, now relay K 1 coil losing electricity, relay K 1 open contact transfers open-circuit condition to, and now function Warning light knocks out.Treater U4 stateless inputs, mouth Non voltage output, relay K 2, the whole dead electricity of K3 relay coil, then the normally closed contact of relay K 2, K3 is kept closed, cart left lateral and very fast instruction are connected, and overhead traveling crane can continue to run left, and hoisting crane can arbitrarily in region inner position.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
