Specific embodiment
Below in conjunction with attached drawing, the preferred embodiment of the utility model is described in detail.
As shown in Figure 1, a kind of rotor string resistance formula bridge crane anti-collision system, including detection system, control system and
Ramp to stop system；
The detection system includes the laser sensor for being mounted on cart both ends, and the laser sensor is adjacent for acquiring
Between two carts, cart between the walls or the distance between cart and other barriers information；
The control system is preset with big for receiving laser sensor collected range information in the control system
Vehicle safe distance and barrier safe distance；
The ramp to stop system is used between adjacent two cart, cart and between the walls or between cart and barrier
Distance X be less than deceleration distance when cart rotor series resistance speed circuit is cut off, when the distance X be less than parking away from
From when cart major loop starting contactor coil is cut off.
The ramp to stop system include with the concatenated deceleration relay of the first output point of laser sensor, with laser sensing
The concatenated plugging relay of the second output point of device, the deceleration relay close point controls two deceleration contactor coils, described to subtract
Fast contactor coil is connected among the resistor and movable motor rotor of cart；The plugging relay corresponds to two of cart
Direction of travel includes stop port relay and right plugging relay, and the plugging relay close point control has walking contactor line
Circle, the walking contactor coil are connect with large vehicle walking cam, and the left lateral and right lateral of cart are controlled by positive and negative rotation.
Further include that setting is driving indoor warning device, control is prescribed by deceleration relay, for carrying out to driver
Warning reminding is alarmed using buzzer in the present embodiment.
Original part is detected by laser sensor, detection crane closes on barrier (other cranes, equipment, workshop edge
Deng), provide it is double acting make contact output, by control loop, power loop, speed control loop be transformed, increase anticollision automatic retarding stop
Vehicle function, and synchronous increase rings news warning device, to remind driver's crane state.
It is left to increase cart in former electrical schematic diagram for the first part (a) of control loop and second part (b) referring to fig. 2
Capable and right lateral stops function and anti-collision retarding contactor coil.In cam control contactor action circuit, connect by laser
Sensor stops the close point of output point control relay, which is functionally equivalent to stroke limit at left and right sides of large vehicle walking and opens
It closes.Increase by the close point of laser sensor deceleration output point control relay, controls two contactor coil movements.
Referring to Fig. 3 power loop, is slowed down in Fig. 2 by laser sensor and export the master of two contactors of point relay control
Contact is connected in cart movable motor rotor string resistance circuit, and when the output of laser sensor signal, contactor coil is lost
Electricity realizes deceleration so that resistance is connected in series in speed control loop.
Detecting element schematic diagram referring to fig. 4 increases direct current 24V power supply, drives laser sensor, when laser sensor detects
Distance reach deceleration distance when, export KA1 relay, when detecting distance reach stop distance when, corresponding direction export KA2 and
KA3.It is acted by the contact of three above relay, controls contactor movement in major loop, realize purpose.
Referring to Fig. 5, increases warning device in driver's cabin, buzzer can be selected in the present embodiment, prescribed by KA1 relay
It controls (KA1 is deceleration relay), KA1, which is prescribed, to be parallel on driver's cabin sound news switch, when crane operation, is risen apart from other
When heavy-duty machine or barrier, KA1 movement exports driver's cabin buzzer, plays the function of prompt driver.
Since in the crane of cam controller control crane movement and speed regulation, control loop and major loop are all by convex
Wheel controller undertakes, and motor action is controlled by contact closure, and voltage class is 380V in circuit, and carrying size of current depends on
The power of controlled motor, all sensors, limit all obtain low voltage product, not can be used directly in cam control system,
Cause existing old-fashioned rotor string resistance crane control mode simple, the uneven congruent existing issue of function, this programme is electrically returning
Contactor transfer is added in road, major loop and control loop is separated, to upgrade to old-fashioned rotor string resistance crane, greatly
Lift crane use safe and personal safety.
Finally, it is stated that preferred embodiment above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, to the greatest extent
Pipe has been described in detail the utility model by above preferred embodiment, but those skilled in the art should manage
Solution, can make various changes, without departing from the utility model claims book institute to it in the form and details
The range of restriction.
