Abstract
The utility model discloses a crane rotary brake control system. The crane rotary brake control system adopts a relay X R G I 2 and a 48 V A C output end of a control button X G I and a transformer T S R to form a duct pilot. A relay X R G I 2-1 and a relay X R G I 2-2 respectively controls a brake coil R F s and a weathervane coil G I F a. Compared with the prior art, the control voltage of the crane rotary brake control is 48 V A C safe voltage, one relay is saved, the cost is reduced, and the crane rotary brake control system also can be a portable operating control. The voltage of the relay coil of the crane rotary brake control system is 48 volts while the voltage of the relay coil of the existing rotary brake pilot circuit is 380 volts, and the crane rotary brake control system is applicable to other devices and meets national and international standards.
Description
One, affiliated technical field
The utility model belongs to the hoisting crane supporting technology, is specifically related to a kind of electric control system of tower crane, particularly the crane rotation brake control system.
Two, background technology
According to the national standard requirement, if tower type crane slewing gear adopts normally closed brake, when entering off working state, the tower machine should by manual or remote control mode brake off, jib can be rotated with the wind.Jib is the wind area of rotational minimizing tower machine steel structure with the wind, guarantees the safety of tower machine under off working state.
Manually the brake off mode is all the same, does not narrate here.Remote control mode uses 380VAC voltage to control always, controls by updating to use than the low dc voltage grade, but all needs more or less increase device, and circuit is comparatively loaded down with trivial details, and commonality is bad.
Three, summary of the invention
The purpose of this utility model provides and a kind ofly can improve product commonality and safety, reduces the crane rotation brake control system of cost.
The technical solution adopted in the utility model is: the crane rotation brake control system adopts the 48VAC mouth of a relay XRGi2 and control button XGi and voltage transformer TSR to consist of control loop, and relay contact one XRGi2-1 and relay contact two XRGi2-2 control respectively brake coil RFs and weathercock coil GiFa.
Contrast trainstop control circuit commonly used, control voltage of the present utility model is the 48VAC safety voltage; Save a relay, reduced cost; Also can make portable operating control.Trainstop control circuit relay coil voltage commonly used is 380V, and relay coil voltage of the present utility model is 48V, and is general with other devices, meets country, international standard.
Four, description of drawings
Fig. 1 is crane rotation brake control system schematic diagram commonly used;
Fig. 2 is schematic circuit diagram of the present utility model;
Fig. 3 is the physical construction schematic diagram (closure state) of trainstop;
Fig. 4 is the physical construction schematic diagram (open mode) of trainstop.
Five, the specific embodiment
Existing trainstop control circuit commonly used is to be made of two 380VAC relays, its working process is: in relay XRGi1 and relay XRGi2 connection, voltage transformer TSR is charged, through circuit breaker Red1Di, after the diode Red1 rectification, send into drg RFs weathercock coil GiFa.Press button XGi, XRGi1-1 contacting, contacting be the charged connection of relay XRGi2 after 1 second.While relay XRGi1-2 contacting, weathercock coil GiFa energising is with the adhesive of weathercock armature clamp; Before relay XRGi2 connects, because its contact XRGi2-1 is normally closed OFF state, so brake coil RFs energising adhesive, after 1 second, the charged connection of relay XRGi2, its contact XRGi2-1 disconnects, and drg RFs releases of cut off the power supply is owing to weathercock coil GiFa switches on, the adhesive of weathercock armature clamp, therefore its drg RFs mechanics contacts with weathercock armature clamp, and drg RFs is blocked, and makes drg be in all the time the state of beating.This moment release button XGi, the weathercock control system is finished the work.
The utility model adopts the input end of 380VAC power supply access voltage transformer TSR, open contact and the relay XRGi2 coil of the mouth series connection control button XGi of the 48VAC of voltage transformer TSR; Another group mouth of voltage transformer TSR, wherein center-point accesses the end of brake coil RFs and weathercock coil GiFa, two ends connect respectively the anode of rectifier diode Red1 through circuit breaker Red1Di in addition, the negative electrode of diode Red1 is succeeded respectively appliance contact one XRGi2-1 and relay contact two XRGi2-2 one end, the end of another termination brake coil RFs of relay contact one XRGi2-1; The give a dinner for a visitor from afar other end of graticule circle GiFa of the other end of relay contact two XRGi2-2.
Its principle of work is: connect the 380VAC power supply, voltage transformer TSR is charged, through circuit breaker Red1Di, after the diode Red1 rectification, sends into brake coil RFs and weathercock coil GiFa.Press button XGi, the charged connection of relay XRGi2, relay contact one XRGi2-1 connects, brake coil 4(RFs) the energising adhesive, and relay contact two XRGi2-2 connect simultaneously, and weathercock coil GiFa energising is with 2 adhesives of weathercock armature clamp.When release button XGi, drg RFs is owing to relay contact one XRGi2-1 cuts off the power supply, this moment is because relay contact two XRGi2-2 still are in on-state, be weathercock coil 3(GiFa) energising, with 2 adhesives of weathercock armature clamp, drg mechanics 1 contacts with weathercock armature clamp 2, drg mechanics 1 is blocked, make drg be in all the time the state of opening, after 1 second, relay contact two XRGi2-2 disconnect, but since mechanics risen and done usefulness, so weathercock coil 3(GiFa) whether switch on unimportant.The crane rotation brake control system is finished the work.
