Abstract
The invention relates to a driving cart brake delay braking circuit. The driving cart brake delay braking circuit comprises a main power supply branch, a driving brake motor branch and a driving cart motor branch, and further comprises a delay relay branch in parallel connection with the driving brake motor branch, wherein the delay relay branch is composed of a delay relay and a delay disconnection contact which are in series connection. The delay disconnection contact is a delay disconnection normally closed contact. The driving cart brake delay braking circuit can achieve the purposes of energy conservation and cost reduction, and can also reduce accidents caused by over-fast power-off speed due to sudden failure in the driving.
Description
Technical field
The present invention relates to electromagnetic control circuit, be particularly applied to the band-type brake control circuit of mill travelling crane truck.
Background technology
Existing travelling crane truck to be adopted direct power-off band-type brake to slow down to control, and when handle is placed in zero-bit and stops, easily occurs the too fast situation such as plunge off the tracks of road speed, and when reversing braking electric energy loss and vibration excessive.
Summary of the invention
For above-mentioned defect of the prior art, the invention provides a kind of travelling crane truck delay contracting braking circuit, guaranteed that travelling crane truck can effectively come to a complete stop when braking.
For reaching above object, the present invention is by the following technical solutions: travelling crane truck delay contracting brake circuit, comprise general supply branch road, driving band-type brake motor branch road, travelling crane truck motor branch road, it is characterized in that: also comprise and slug relay's branch road of driving band-type brake motor branch circuit parallel connection, route slug relay is propped up by described slug relay and time delay break contact is composed in series.
Described time delay break contact is that time delay disconnects normally closed contact.
Preferably, the limit switch of connecting after driving band-type brake motor branch road, is used for the cargo motor garage of being expert to sail to when certain limits position and stop.
Described general supply branch road comprises general supply adhesive contactless switch and safety interlocking point, prevents in band-type brake motor main circuit non-transformer situation cargo motor action and burn out motor.
Described limit switch comprises motor forward limit switch and motor reversal limit switch, corresponding, and travelling crane truck motor branch road comprises the positive contactor of motor and reversion contactless switch, also has 2,3,4 grades of contactless switchs of travelling crane truck simultaneously.
The present invention reaches following useful technique effect: both reached the object of energy saving and cost lowering, and also reduced the safety misadventure that driving causes because of the fault power-off excessive velocities happening suddenly.
Accompanying drawing explanation
Fig. 1 is travelling crane truck delay contracting braking circuit constructional drawing of the present invention.
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, general supply branch road, for switching on and off power supply to driving band-type brake motor branch road, slug relay's branch road and travelling crane truck motor branch road, comprises general supply adhesive contactless switch K01 and safety interlocking point; Driving band-type brake motor branch road comprises driving band-type brake motor contactless switch K02, is used for start and stop band-type brake motor to discharge and locking travelling crane truck running roller; Travelling crane truck motor branch road is included as the time delay of cargo motor contactless switch and obtains electric time relay K03; Slug relay's branch road comprises the K04 of slug relay and its time delay break contact, and this contact is that time delay disconnects normally closed contact.Slug relay's branch road and driving band-type brake motor branch circuit parallel connection.
During operation, when co-acting lever reaches zero-bit, travelling crane truck motor control signal disappears, the K04 of slug relay immediately electric, now the band-type brake contactless switch K02 of cargo motor always electric, driving can not stop immediately, after the K04 of slug relay time delay 5s, discharge afterwards, the band-type brake motor contactless switch K02 of cargo motor just discharges, and now drives a vehicle and is embraced steadily and stop by band-type brake.
Increase after delay function, effectively prevented from shaking when driving from stopping excessive, extended service life of travelling facility, also improved the operating efficiency of shop traveller.
Be more than better embodiment of the present invention, but protection scope of the present invention is not limited to this.Any those of ordinary skill in the art are in the disclosed technical scope of the present invention, and the conversion of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore protection scope of the present invention should be as the criterion with the protection domain that claim was limited.
