The accompanying drawing explanation
below in conjunction with accompanying drawing and concrete embodiment, the present invention will be further described in detail.
fig. 1 is for to look schematic diagram according to the master of safe locking mechanism of the present invention;
the elevational schematic view that Fig. 2 is buckle structure in Fig. 1;
wherein: 1, underframe; 2, snap close; 20, snap close body; 21, roller; 22, fastener; 3, dead bolt; 30, dead bolt seat; 31, latch hook frame; 32, latch hook; 33, contiguous block; 34, tapered end; 4, gate is opened passage; 40, stopper; 5, power wheel; 6, messenger chain; 7, spring perch; 8, Compress Spring; 9, contact switch; 10, controll block; 11, bearing pin; A, locked groove; B, salient; C, Transmission.
The specific embodiment
the safe locking mechanism of the elevator cage door of the present embodiment, its main purpose is, and when car movement, in the flat bed zone time, lockout mechanism is release voluntarily, and gate can be opened safely; When car movement, in non-flat layer region the time, lockout mechanism is sealed voluntarily, guarantees that gate can't normally open.Therefore, in order to realize the purpose 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 on 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 the side with snap close body 20 of roller 21 is stretched out car body, what roller 21 can rotate around the Pivot Point Center line is arranged on snap close body 20, also be provided with the bearing pin 11 perpendicular to underframe 1 on underframe 1, snap close body 20 can rotate and arrange around bearing pin 11.
above-mentioned dead bolt 3 comprise dead bolt seat 30, the upper end that can move up and down along the car body short transverse be fixed on latch hook frame 31 on dead bolt seat 30, be arranged on actively latch hook frame 31 bottoms 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 on car body and control the control system that power wheel 5 rotates, dead bolt seat 30 is arranged on messenger chain 6, drives dead bolt 3 by messenger chain 6 and moves up and down along the car body short transverse.
by the setting of above-mentioned snap close 2, dead bolt 3 and driver train, when car movement, in non-flat layer region the time, snap close is relative with dead bolt to be locked, and now, gate can't normally be opened; To in the flat bed zone time, by hitting contacting of bow and roller 21, make 20 rotations of snap close body when car movement, 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 the gate short transverse along parallel, and is provided with locked groove a, and fastener 22 is opened the direction setting along gate, 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 are opened passage 4.Be provided with rotating stopper 40 in gate is opened passage 4, contiguous block 33 can be conflicted on stopper 40 simultaneously.Also be fixedly connected with the Transmission c be connected with messenger chain 6 on latch hook 32, 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, 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, makes gate normally to open.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 the flat bed zone, now, the safe locking mechanism release, gate can be opened safely, its operating process is as follows, when roller with hit bow while contacting, the snap close body rotates around bearing pin, make the tapered end of fastener and dead bolt thread off, simultaneously by being arranged on contacting of controll block on the snap close body and contact switch, make contact switch be connected with the control system of driver train, make power wheel rotate, conveyer chain rotates counterclockwise, make the length direction upward movement of the dead bolt seat of dead bolt along messenger chain, while latch hook and dead bolt seat reverse movement, thereby driving contiguous block moves down, the stopper that makes contiguous block and gate open passage breaks away 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 can't normally be opened, and its operating process is as follows, roller with hit bow and break away from, the snap close body restores to the original state under the effect of Compress Spring, controll block on the snap close body and contact switch break away from simultaneously, make snap close and dead bolt recover the elevator normal operating condition, now, it is that stopper blocks that gate is opened passage, and gate can't 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 to gate and open passage, guarantee that gate can't open, be provided with and hit bow in the flat bed zone, and roller is arranged on to the car body outside simultaneously, by roller with hit the 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 invention simple in structure, it is convenient to implement, and cost is lower.
above the present invention is described in detail, but the invention is not restricted to the embodiments described.The equivalence that all Spirit Essences according to the present invention are done changes or modifies, and all should be encompassed in protection scope of the present invention.
