Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of portal crane lock of safety door for subway station that the present invention proposes, it comprises: an installing plate 6, be located at special-shaped rotating disk 12 on the left of installing plate 6, be located at the U-shaped installing rack 2 of installing plate 6 right lateral surface, be laterally located at the electromagnet 1 with connector socket 19 outside this installing rack, the linkage unit 5 be located in this installing rack 2.Be located at the connecting axle 8 in this linkage unit, its left end passes installing plate 6, the right-hand member of this connecting axle 8 connects relatively with the iron mandrel 18 of electromagnet 1, a Compress Spring 3 to be placed in iron mandrel 18 and to be located between linkage unit 5 and electromagnet 1 side.Shown in Fig. 3, Fig. 5, also comprise the limit shaft 22 being fixedly connected on linkage unit 5 side, the left end of this limit shaft 22 passes installing plate 6 and can move back and forth with the synchronous left and right of connecting axle 8, and limit shaft 22 and connecting axle 8 jointly limit or let alone the rotation of described special-shaped rotating disk 12.Shown in Fig. 3, Fig. 4, Fig. 9, in installing plate 6, be provided with a reset tension spring mechanism, swing arm 20 and special-shaped rotating disk 12 coaxial rotation of this mechanism.
In the present embodiment, as Fig. 1, Fig. 2, Fig. 5, shown in Fig. 7, linkage unit 5 comprises an interlock body 501, this interlock body is fixedly connected with described limit shaft 22 on one side, the stage casing cover of connecting axle 8 has a positioning sleeve 17, and fixed by a bearing pin 16, by a jump ring 15, connecting axle 8 is fixed in interlock body 501 again, on the shaft part of installing plate 6 side connecting axle 8, also cover has a soft cushion collar 14, the right-hand member of connecting axle 8 is relative with iron mandrel 18 left end of electromagnet and be threaded, and Compress Spring 3 is placed in iron mandrel 18 and be located between interlock body 501 inner chamber and electromagnet 1 left surface.Shown in composition graphs 3, Fig. 4, reset tension spring mechanism comprises: one end and special-shaped rotating disk 12 are coaxially arranged on the swing arm 20 on installing plate 6, the shaft part be connected with this swing arm is square shaft 40, and the lower end of this swing arm 20 is connected with the left end of extension spring 21, and the right-hand member of extension spring connects on a mounting board 6.Shown in Fig. 3, Fig. 6, Figure 11, the outer rim of special-shaped rotating disk 12 is interval with the stopper slot 121 inserted for connecting axle 8, and the stopper slot 122 inserted for limit shaft 22 and the spring lock axle 30 be also provided with for sliding door hit the groove 123 touched.The outer of linkage unit 5 is arranged with the first, second, third and fourth sense switch 4,9,10,11 that detection linkage unit moves back and forth position.According to user's needs, sense switch can adopt mechanical quick-action switch, or photoelectric sensor switch etc.
As shown in Fig. 1 ~ Fig. 6, it be locking states metro safety sliding door of the present invention L slip left behind the door that sliding door closes, and the spring lock axle 30 be fixedly connected with sliding door clashes into portal crane lock
abnormity rotating disk12 make its up time rotate an angle after, connecting axle 8 and limit shaft 22 are moved to the left under the effect of Compress Spring 3, and insert two stopper slots 121,122 of special-shaped rotating disk 12 respectively, thus limit the left-right rotation of special-shaped rotating disk 12, the spring lock axle 30 of sliding door is stuck in
abnormity rotating diskgroove 123 in be defined so that sliding door can not continue slide.Meanwhile, swing arm 20 is rotated with the synchronous up time of special-shaped rotating disk 12, and extension spring 21 is stretched (tension) state under the rotation of swing arm 20, and sliding door is in locking states.After sliding door is closed, the roller disengaging on the first sense switch 4 contacts with the cylindrical of linkage unit 5 and disconnects, and the roller on the 4th sense switch 11 contacts and compacted conducting with the cylindrical of linkage unit 5, and locking signal imports a machine controller into; Roller on second and third sense switch 9,10 contacts and compacted conducting with the cylindrical of linkage unit 5, and locking signal imports security of system loop into.Whole process completes the locking of sliding door.
As shown in Fig. 8 ~ Figure 11, sliding door close the door after portal crane lock locking states, when sliding door to the right R move need to open time, electromagnet 1 is energized, and under the suction of electromagnet, connecting axle 8 and limit shaft 22 move right, and depart from special-shaped rotating disk 12, at this moment, swing arm 20 is rotated with the special-shaped rotating disk 12 synchronous inverse time under the pulling force effect of extension spring 21, thus spring lock axle 30 is departed from
abnormity rotating diskgroove 123, remove locking states, sliding door is opened, and sliding door just can move freely.While connecting axle 8 and limit shaft 22 move right, the roller on the first sense switch 4 contacts compacted conducting with the cylindrical of linkage unit 5, and the enabling signal of detection imports a machine controller into; Second sense switch 9, the 3rd sense switch 10 and the 4th sense switch 11 etc. are all disconnected, and the enabling signal of detection imports security of system loop into, departs from the spring lock axle 30 of sliding door
abnormity rotating diskgroove 123 after, electromagnet 1 auto-breaking, the front end of connecting axle 8 and limit shaft 22 is pressed in left after special-shaped rotating disk 12 under the effect of Compress Spring 3, and portal crane lock is opening all the time.When needs manual unlocking, can operate the manual unlocking handle be contained on sliding door, order about connecting axle 8 by an apical axis and move right, sliding door can be manually opened.
Simple, the convenient debugging of the portal crane lock structure of the present invention's design and safeguard, good reliability, guarantee an energy locking when the door closes, when door need be opened, can automatically and manually opened.
