The specific embodiment
the safe locking mechanism of the elevator cage door of the present embodiment, its main object is, and when car movement is in flat bed region time, lockout mechanism is release voluntarily, and gate can be opened safely; When car movement is in non-flat layer region time, lockout mechanism is sealed voluntarily, guarantees that gate cannot normally open.Therefore,, in order to realize the object of above-mentioned lockout mechanism, the lockout mechanism concrete structure adopting in this example is as follows:
as depicted in figs. 1 and 2, the safe locking mechanism of the present embodiment, it comprises and is arranged on underframe 1 in car body, is arranged on snap close 2 on underframe 1, controls the dead bolt 3 that gate opens and drive snap close 2 release relative to dead bolt 3 or sealed driver train.
what above-mentioned snap close 2 comprised rotation is arranged on the snap close body 20 on underframe 1, the roller 21 that is separately positioned on snap close body 20 both ends and fastener 22, the direction setting that snap close body 20 is opened along gate, and a side with the snap close body 20 of roller 21 is stretched out car body, what roller 21 can rotate around Pivot Point Center line is arranged on snap close body 20, on underframe 1, be also provided with the bearing pin 11 perpendicular to underframe 1, snap close body 20 can rotate and arrange around bearing pin 11.
above-mentioned dead bolt 3 comprise the dead bolt Zuo30, upper end that can move up and down along car body short transverse be fixed on latch hook frame 31 on dead bolt seat 30, be arranged on actively latch hook Jia31 bottom latch hook 32, be hung on latch hook 32 and can block gate and open the contiguous block 33 of passage 4 and the tapered end 34 that can lock together with fastener 22.
above-mentioned driver train comprises that being arranged on hitting on flat bed area level door bends (not shown), be arranged on power wheel 5 and the messenger chain 6 in car body and control the control system that power wheel 5 rotates, dead bolt seat 30 is arranged on messenger chain 6, by messenger chain 6, drives dead bolt 3 to move up and down along car body short transverse.
by the setting of above-mentioned snap close 2, dead bolt 3 and driver train, when car movement is in non-flat layer region time, snap close is relative with dead bolt to be locked, and now, gate cannot normally be opened; When car movement is in flat bed region time, by hitting contacting of bow and roller 21, make 20 rotations of snap close body, thereby make tapered end 34 dropouts of fastener 22 and dead bolt 3, and then realize the release of lockout mechanism, now, gate can be opened safely.
yet for above-mentioned lockout mechanism, the switching of sealed and release is respectively equipped with spring perch 7 on underframe 1 and snap close body 20, lockout mechanism also comprises and is arranged on two Compress Springs 8 between spring perch 7.When hitting bow while contact with roller 21, snap close body 20 rotate relatively, thereby makes Compress Spring 8 that deformation occur, and when hitting, bends and during roller 21 disengaging, Compress Spring 8 will recover state of nature, causes snap close body 20 to restPose.
above-mentioned lockout mechanism also comprises and is arranged on underframe 1 and can forms the contact switch 9 of C/LOOP and be arranged on the controll block 10 on snap close body 20 with control system, and this controll block 10 can be conflicted and on contact switch 9, be made contact switch 9 and control system form C/LOOP.
tapered end 34 in this example arranges with gate short transverse along parallel, and is provided with locked groove a, and fastener 22 is opened direction setting along gate, and is provided with the salient b extending to car body, and salient b engages with locked groove a is vertical.It is vertical and shift to install that latch hook 32 and gate are opened passage 4.In gate is opened passage 4, be provided with rotating stopper 40, contiguous block 33 can be conflicted on stopper 40 simultaneously.On latch hook 32, be also fixedly connected with the Transmission c being connected with messenger chain 6, described Transmission c and dead bolt seat 30 are separately positioned on the left and right sides of messenger chain 6, and Transmission c is positioned at the below of dead bolt seat 30, that is to say, when dead bolt seat 30 is during along car body short transverse upward movement, Transmission c band moveable lock hook 32 moves downward.
the present embodiment, according to above-mentioned concrete structure, concrete state is as follows:
when elevator normally moves, dead bolt and snap close are normally sealed, and the attaching parts of dead bolt is conflicted and opened on the stopper of passage at elevator cage door simultaneously, makes stopper block gate and opens passage, and gate cannot normally be opened.When elevator need to be shut down, there are two kinds of situations, the first is orderly closedown, the elevator cage operation of namely often saying is to flat bed region, now, safe locking mechanism release, gate can be opened safely, its operating process is as follows, when roller with hit bow while contacting, snap close body rotates around bearing pin, the tapered end of fastener and dead bolt is threaded off, simultaneously by being arranged on contacting of controll block on snap close body and contact switch, contact switch is connected with the control system of driver train, power wheel is rotated, conveyer chain rotates counterclockwise, make the dead bolt seat of dead bolt along the length direction upward movement of messenger chain, while latch hook and dead bolt seat reverse movement, thereby drive contiguous block to move down, the stopper that makes contiguous block and gate open passage departs from, now, it is unblocked that gate is opened passage, gate can be opened safely, under normal circumstances, the elevator cage operation of namely often saying is to non-flat layer region, now for the second right and wrong, safe locking mechanism is sealed, gate cannot normally be opened, and its operating process is as follows, roller with hit bow and depart from, snap close body restores to the original state under the effect of Compress Spring, controll block on snap close body and contact switch depart from simultaneously, make snap close and dead bolt recover elevator normal operating condition, now, it is that stopper blocks that gate is opened passage, and gate cannot be opened.
in sum, elevator of the present utility model is in non-flat layer region, sealed by fastener and tapered end, and contiguous block is blocked to gate and open passage, guarantee that gate cannot open, in flat bed region, be provided with and hit bow, and roller is arranged on to car body outside simultaneously, by roller with hit bow contact, make the rotation of snap close body, cause fastener and tapered end release, make contiguous block avoid gate and open passage, thereby gate can be opened safely, improve the safety of elevator ride, in addition, of the present utility model simple in structure, it is convenient to implement, and cost is lower.
above the utility model is described in detail, but the utility model is not limited to the above embodiments.All equivalences of doing according to Spirit Essence of the present utility model change or modify, and all should be encompassed in protection domain of the present utility model.
