Description
Technical field
The present invention relates to a kind of portal crane lock for metro platform shield door and safety door.
Background technology
Along with the 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 to close, and prevents accident.Existing portal crane lock mechanism kinematic for subway shield door and safety door is complicated, and part processing and assembly precision require high, has increased technical difficulty for field adjustable and maintenance, and in addition, manufacturing cost is also high.
Summary of the invention
The present invention seeks to propose a kind of portal crane lock for subway shield door and safety door in order to solve above-mentioned problems of the prior art.
The technical solution used in the present invention 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, and the right-hand member of the left end of this slide bar and a horizontally disposed hinge bar is pivotally connected;
Locking bar, it is fixed on the below of base plate by a rotating shaft, this locking bar is horizontally disposed with, can rotate up and down around the shaft, a connecting rod is vertically stretched out at the middle part of described locking bar, the end of this connecting rod and the left end of described hinge bar are pivotally connected, and the two ends of described locking bar are provided with the latch hook of 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 of left end and described locking bar is pivotally connected, is provided with successively return spring and cushion pad 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 described locking bar stretches out, be used for the rotational angle of restriction locking bar.
Compared with prior art, the portal crane lock of the present invention design is simple in structure, make things convenient for debugging and maintenance, good reliability, guarantees an energy locking when door is closed, when door need be opened, and can be automatically and manually opened.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples, wherein:
Fig. 1 is the schematic diagram that portal crane lock of the present invention is in locking states;
Fig. 2 is the schematic diagram that portal crane lock of the present invention is in opening.
The specific embodiment
As shown in Figure 1, the portal crane lock that the present invention 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 at its two ends, and the right-hand member of the left end of this slide bar and a horizontally disposed hinge bar 6 is pivotally connected;
With gag lever post 13, be arranged on the base plate 1, be positioned at the right side of connecting rod 8, be used for the rotational angle of restriction 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 namely is in locking states.At this moment, by 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 breaks away from latch hook 16, the electromagnetic core auto-breaking, locking bar 7 is got back to horizontal level under the effect of return spring 11.
When the needs manual unlocking, but the backguy 12 of manually unblanking that arranges on the actuating pull bar 9 makes latch hook turn to suitable angle, and door can be opened.
Being articulated and connected of hinge bar 6 two ends can keep electromagnetic core to be in all the time horizontal movement, 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.
