Detailed description of the invention
the safe locking mechanism of the elevator cage door of the present embodiment, its main object is, when in car movement to flat bed region, lockout mechanism unlocks voluntarily, and gate can be opened safely; When car movement in non-flat layer region time, lockout mechanism is sealed voluntarily, guarantees that gate cannot normally be opened.Therefore, in order to realize the object of above-mentioned lockout mechanism, the lockout mechanism concrete structure adopted 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, the snap close 2 be arranged on underframe 1, controls the dead bolt 3 opened of gate and drive that snap close 2 is relative with dead bolt 3 to be unlocked 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 being separately positioned on snap close body 20 both ends and fastener 22, snap close body 20 is arranged along the direction that gate is opened, and car body is stretched out in the side with the snap close body 20 of roller 21, what roller 21 can rotate around Pivot Point Center line is arranged on snap close body 20, underframe 1 is also provided with the bearing pin 11 perpendicular to underframe 1, snap close body 20 can rotate around bearing pin 11 and arrange.
above-mentioned dead bolt 3 comprises dead bolt seat 30, the upper end that can move up and down along car body short transverse and is fixed on latch hook frame 31 on dead bolt seat 30, is arranged on the latch hook 32 of latch hook frame 31 bottom actively, is hung on latch hook 32 and can blocks the contiguous block 33 that gate opens passage 4 and the tapered end 34 that can lock together with fastener 22.
above-mentioned driver train comprises and is arranged on hitting bow (not shown), be arranged on power wheel 5 in car body and messenger chain 6 and control the control system that power wheel 5 rotates on flat bed area level door, dead bolt seat 30 is arranged on messenger chain 6, drives dead bolt 3 to move up and down along car body short transverse by messenger chain 6.
by the setting of above-mentioned snap close 2, dead bolt 3 and driver train, when car movement in non-flat layer region time, snap close is relative with dead bolt to be locked, and now, gate cannot normally be opened; When in car movement to flat bed region, by hitting bow and the contact of roller 21, snap close body 20 is rotated, thus fastener 22 is threaded off with the tapered end 34 of dead bolt 3, and then realize the unblock of lockout mechanism, now, gate can be opened safely.
but in order to above-mentioned lockout mechanism, the sealed switching with unlocking, underframe 1 with snap close body 20 are respectively equipped with spring perch 7, and lockout mechanism also comprises the Compress Spring 8 be arranged between two spring perches 7.When hitting bow and contacting with roller 21, snap close body 20 rotates relatively, thus makes Compress Spring 8 that deformation occur, and when hitting bow and departing from roller 21, 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 the contact switch 9 that underframe 1 can form C/LOOP with control system and the controll block 10 be arranged on snap close body 20, and this controll block 10 can be conflicted and be made contact switch 9 and control system form C/LOOP on contact switch 9.
tapered end 34 in this example is arranged along parallel with gate short transverse, and is provided with locked groove a, and fastener 22 is arranged along gate opening direction, and is provided with the salient b extended 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 open passage 4.Open in passage 4 at gate simultaneously and be provided with rotating stopper 40, contiguous block 33 can be conflicted on stopper 40.Latch hook 32 is also fixedly connected with the Transmission c be 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, when dead bolt seat 30 is along car body short transverse upward movement, Transmission c is with moveable lock hook 32 to move downward.
the present embodiment, according to above-mentioned concrete structure, concrete state is as follows:
when elevator normally runs, 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, gate cannot normally be opened.When elevator needs to shut down, there are two kinds of situations, the first is orderly closedown, the elevator cage operation namely often said is in flat bed region, now, safe locking mechanism unlocks, gate can be opened safely, its operating process is as follows, when roller with hit bend contact time, snap close body rotates around bearing pin, the tapered end of fastener and dead bolt is threaded off, simultaneously by the contact of the controll block be arranged 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 length direction upward movement of dead bolt seat along messenger chain of dead bolt, latch hook moves contrary with dead bolt seat simultaneously, thus drive contiguous block to move down, the stopper making contiguous block and gate open passage departs from, now, it is unblocked that gate opens passage, gate can be opened safely, under normal circumstances, the elevator cage operation namely often said is extremely in non-flat layer region for the second right and wrong, now, safe locking mechanism is sealed, gate cannot normally be opened, and its operating process is as follows, and roller departs from hitting to bend, snap close body restores to the original state under the effect of Compress Spring, be in controll block on snap close body and contact switch departs from simultaneously, make snap close and dead bolt recover elevator normal operating condition, now, it is that stopper blocks that gate opens passage, and gate cannot be opened.
in sum, elevator of the present invention is in non-flat layer region, sealed by fastener and tapered end, and contiguous block is blocked gate open passage, guarantee that gate cannot be opened, be provided with in flat bed region simultaneously and hit bow, and roller is arranged on outside car body, contacted with hitting to bend by roller, snap close body is rotated, causes fastener and tapered end to unlock, make contiguous block avoid gate and open passage, thus gate can be opened safely, improve the safety of elevator ride, in addition, structure of the present invention is simple, it is convenient to implement, and cost is lower.
above to invention has been detailed description, but the invention is not restricted to the embodiments described.The equivalence change that all Spirit Essences according to the present invention are done or modification, all should be encompassed in protection scope of the present invention.
