Description

Portal crane lock

Technical field

The utility model relates to a kind of portal crane lock that is used for subway platform shield door and safety door.

Background technology

Along with development of Urban Traffic, the use of subway is more and more universal.Because how crowded the subway platform people is, safety is the problem of overriding concern in numerous technical indicators.When launch train, the shield door of subway platform, or safety door generally need close, and prevents accident.The existing portal crane lock mechanism kinematic complicacy that is used for subway shield door and safety door, part processing and assembly precision require high, have increased technical difficulty for field adjustable and maintenance, and in addition, manufacturing cost is also high.

Summary of the invention

The utility model purpose is the problem that exists in the above-mentioned prior art in order to solve, and proposes a kind of portal crane lock that is used for subway shield door and safety door.

The technical scheme that the utility model adopts is, designs a kind of portal crane lock, comprising:

Base plate; The both sides of this base plate are equipped with left location switch and right location switch, are provided with the electromagnetic core that is connected with door controller between the location switch of the left and right sides, and this electromagnetic core can move horizontally; And a slide bar is stretched out at its two ends, the right-hand member pivotal connection of the left end of this slide bar and a horizontally disposed hinge bar;

Locking bar; It is fixed on the below of base plate through a rotating shaft, and this locking bar is horizontally disposed with, and can rotate up and down around the shaft; A connecting rod is vertically stretched out at the middle part of said locking bar; The left end pivotal connection of the end of this connecting rod and said hinge bar, the two ends of said locking bar are provided with latch hook in the opposite direction, and this latch hook cooperates with lock pin on being arranged on a body;

Pull bar is horizontally disposed with, and the connecting rod middle part pivotal connection of left end and said locking bar is provided with return spring and cushion pad successively on the pull bar;

And gag lever post, be arranged on the base plate, be positioned at the right side of the connecting rod that said locking bar stretches out, be used to limit the rotational angle of locking bar.

Compared with prior art, the portal crane lock of the utility model design is simple in structure, make things convenient for debugging and maintenance, good reliability, when door is closed, guarantees an ability locking, when door need be opened, and can be automatically with manually opened.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further, wherein:

Fig. 1 is the sketch map that the utility model portal crane lock is in locking states;

Fig. 2 is the sketch map that the utility model portal crane lock is in opening.

The specific embodiment

As shown in Figure 1, the portal crane lock that the utility model proposes has automatically and the hand switch lock function, comprising:

Base plate 1; The both sides of this base plate are equipped with left location switch 2 and right location switch 3; Be provided with the electromagnetic core 4 that is connected with door controller between the location switch of the left and right sides; This electromagnetic core can move horizontally, and a slide bar 5 is stretched out, the right-hand member pivotal connection of the left end of this slide bar and a horizontally disposed hinge bar 6 in its two ends;

Locking bar 7; It is fixed on the below of base plate 1 through rotating shaft 15, and this locking bar is horizontally disposed with, and can 15 rotate up and down around the shaft; A connecting rod 8 is vertically stretched out at the locking bar middle part; The left end pivotal connection of the end of this connecting rod and hinge bar 6, the two ends of locking bar 7 are provided with latch hook in the opposite direction 16, and this latch hook cooperates with lock pin 14 on being arranged on a body;

Pull bar 9 is horizontally disposed with, and the connecting rod 8 middle part pivotal connections of left end and locking bar are provided with return spring 11, cushion pad 10 and the backguy 12 of manually unblanking successively on the pull bar;

With gag lever post 13, be arranged on the base plate 1, be positioned at the right side of connecting rod 8, be used to limit the rotational angle of locking bar.

As shown in Figure 1, when among the Men Tixiang figure during direction of arrow closing movement, lock pin 14 bump locking bars 7; Make its angle that turns right, after the motion of closing the door puts in place, under the effect of return spring 11; Locking bar 7 is got back to illustrated horizontal level, and latch hook 16 is locked with lock pin 14, and door promptly is in locking states.At this moment, through the connecting rod 8 left location switch 2 of conflicting, this switch detects locking signal that puts in place.

As shown in Figure 2, when the direction of arrow is opened the door among the Men Tixiang figure, under the suction of electromagnetic core 4; Locking bar 7 angle that turns right; Remove the spacing of lock pin 14 on the latch hook 16 opposite house bodies, the tail end of the slide bar 5 at electromagnetic core middle part and 3 conflicts of right location switch make switch conduction simultaneously; Detect enabling signal, door can be towards the direction motion of opening the door.After lock pin 14 broke away from latch hook 16, electromagnetic core cut off the power supply automatically, and locking bar 7 is got back to horizontal level under the effect of return spring 11.

[0010]When the needs manual unlocking, but the backguy 12 of manually unblanking that is provided with on the actuating pull bar 9 makes latch hook turn to suitable angle, and door can be opened.

[0011]Being articulated and connected of hinge bar 6 two ends can keep electromagnetic core to be in horizontal movement all the time, and the hinged employing mounting hole of connecting rod 8 and pull bar 9 can keep the pull bar horizontal movement, thereby avoid producing the resistance of motion.
