Description

Electromagnetic type air door self-locking gear

Technical field

The utility model relates to a kind of air door self-con-tained unit of mine, particularly a kind of electromagnetic type air door self-locking gear.

Background technology

At present, mechanical type air door self-locking gear principle mainly is to utilize wire rope and spring that the ligulate latch of twice air door is connected, and the tongue pin is subjected to the external force interaction energy to be arbitrarily flexible shape.When wherein arbitrary road air door was opened, then wire rope fluffed, and another road air door plays the effect of locking owing to be subjected to the spring tension effect with the automatic knockout pin upper wind door of its ligulate latch.The weak point of above-mentioned mechanical type air door self-locking gear mainly is:

1, because wire rope and spring because of stressed, wearing and tearing for a long time, the distortion situation occurs easily in the middle of the use, adds that the subsurface environment condition is relatively poor relatively, cause locking insensitive even malfunctioning, do not have the effect of automatic blocking;

2, because wire rope has certain pliability, and its locking sensitivity is subjected to certain restriction, actuation time is longer, so the reliability of its locking is relatively poor;

3, the action gap of blocking device debugging is difficult grasps, if the tension that wire rope is transferred, then locking is insensitive, even can not locking; If that transfers is loose excessively, then the choke-out phenomenon appears in device easily, the pedestrian may be blocked outside the return side air door impassable;

4, the blocking of air door is not easy to monitor in real time.

Summary of the invention

The purpose of this utility model is to provide a kind of safety light, sensitive electromagnetic type air door self-locking gear reliably.This air door self-locking gear guarantees that under any circumstance the twice air door can not be opened simultaneously, guarantees distinguished and admirable the stablizing with reliable of ventilation system.

The purpose of this utility model is achieved in that this self-locking gear is made of electromagnetic lock pin and switch, and electromagnetic lock pin is connected with switch and is connected to one group of air damper controller, has two groups of air damper controllers to be connected in parallel on power supply two ends; Wherein, the switch of one group of air damper controller all is to be connected in series with another electromagnetic lock pin of organizing air damper controller; Switch and electromagnetic lock pin are separately fixed on the air door doorframe.

Electromagnetic lock pin has an electromagnet, and electromagnet armature is by one, in flakes two being connected with the ligulate latch in flakes, in flakes two and the junction of ligulate latch be connected with spring; Two be connected on the bolster in flakes.

Beneficial effect: owing to adopt such scheme, the electromagnetic lock pin of self-locking gear is by one and in flakes two being connected with the ligulate latch in flakes, and the switch on one group of air door is connected in the electromagnetic lock pin loop of another air door formation electric-magnetic lock function.When wherein arbitrary road air door is opened by the external force effect, be installed in switch then moment release release, the closing of contact on the air door doorframe, connect the loop of another road air door electromagnetic lock pin by connecting lead moment, the electromagnet coil of electromagnetic lock pin action adhesive, its armature shrink pulling in flakes one the and in flakes two anti-ligulate latches that push away with on the air door pin.Safety is light, sensitive reliable, has reached the purpose of this utility model.The advantage of this electromagnetic type air door self-locking gear is:

1, closedown structure is simple, sensitive reliably, fault rate is low;

2, need not debug in the use, the malfunctioning or choke-out phenomenon of air door can not occur, also can not influence the air door choke-out current even the power supply failed;

3, adopted the cold conditions treatment technology.As can be seen when twice are all closed, circuit is not worked from the course of work, and circuit is just connected when only opening air door.Reduce the running time of device relatively, also prolonged the application life of device;

4, the blocking of air door is convenient to monitor in real time, and the machine room person on duty can in time dispatch and arrange to handle if leak detection power down or circuit break down.

The specific embodiment

Embodiment 1:(1) electromagnet; (2) armature; (3) in flakes one; (4) shell; (5) back-moving spring; (6) in flakes two; (7) bolster; (8) ligulate latch; (9) air door door-hinge; (10) air door handle.

This self-locking gear is made of electromagnetic lock pin DF1, DF2 and K switch 1, K2, and it is one group of air damper controller that electromagnetic lock pin DF1 and K switch 2 are connected in series, and has two groups of air damper controllers to be connected in parallel on power supply two ends; Wherein, the K switch 1 of one group of air damper controller, K2 are connected in series with another electromagnetic lock pin DF2, DF1 that organizes air damper controller; K switch 1 and electromagnetic lock pin DF2 are separately fixed on the frame of air door FM2; K switch 2 and electromagnetic lock pin DF1 are separately fixed on air door FM1 and the frame.Air door air door door-hinge 9 is installed on the air door, and air door handle 10 is arranged on the air door.

Electromagnetic lock pin has an electromagnet 1, and the armature of electromagnet 12 is by one 3, in flakes 26 being connected with ligulate latch 8 in flakes, in flakes 26 and the junction of ligulate latch 8 be connected with back-moving spring 5; 26 be connected on the bolster 7 in flakes.

Employed K switch 1, K2 are micro limit switch.

Its course of work is as follows;

1, as twice air door FM1, when FM2 is in closed condition, the extruding contact that " meeting and discussing " of its travel switch K1, K2 separately is subjected to air door is " disconnection " state, the wire loop no current of the electromagnet 1 of electromagnetic lock pin DF1, DF2 passes through, and armature discharges the promotion brace and the ligulate latch makes the tongue pin be contraction state.If when being connected with monitoring system, voltage sensor arrives the ground monitoring central machine room with " breaking " state transfer of magnet spool simultaneously;

2, when wherein arbitrary road air door is opened by the external force effect, be installed in " meeting and discussing " the then moment release ejection of micro limit switch K1, K2 on the air door, its contact upset " closure ", connect another air door magnet spool loop, road by lead moment, the electromagnet action, the adhesive armature pulling oppositely promotes ligulate latch 8 in flakes with on the air door pin.Voltage sensor is transferred to the ground monitoring central machine room with " leading to " state of electromagnet coil by safety monitoring system simultaneously;

3, when air door was shut, air door propped up travel switch and " meets and discusses ", its contact moment " disconnection ", and dead electricity action in magnet spool loop discharges armature and shrinks the ligulate latch, so that air door is opened the above process of repetition once more, and the like.

One effect is the straight-line trajectory that keeps the ligulate latch in flakes, and two effect is when the electromagnet coil conducting in flakes, makes the tongue pin become " stretching out " state by original " contraction " state, is equivalent to add reverser.Electromagnet was not worked when its benefit was that air door is in closed condition, the Men Shicai that only blows in work.The electromagnet running time reduces relatively, and prolong application life relatively.

This self-locking gear is if be connected with the safety monitoring system online, and then voltage sensor is connected to respectively on general supply and the electromagnet coil loop, as the usefulness of remote measurement blocking.
