The fluency and security of switch gate during layer.Preferably, driven pulley 81 is zigzag.Improve castor 61 and driven pulley 81
Frictional force, be advantageous to timely Acceleration of starting device.
As shown in figure 1, present invention additionally comprises vertical track 7, the vertical track 7 is slidably connected with self-locking structure, described
Vertical track 7 is provided with two, and the vertical track 7 is separately positioned on inside elevator hoistways along the both sides of layer door, i.e., vertical rail
Road 7 runs through whole hoistway, only each to be provided with breakpoint at door layer by layer, above-mentioned driven pulley 81 and is arranged at the breakpoint.Preferably, erect
Track 7 is provided with N number of corrugation bar 71, the corrugation bar 71 sets width is smaller to be only used for increasing frictional force, does not influence to fix chain
Castor 61 tightens again after 62 relaxations.Set corrugation bar 71 to improve frictional force on vertical track 7, be advantageous to from lock machine
Castor 61 drives the fixed action of fixed chain 62 and self-locking shaft 63, the more efficient switch for realizing self-locking structure in structure.
The course of work：During original state, castor 61 is tensioned state with fixed chain 62, i.e., self-locking structure is opened, gate
In the state that can not be opened.For example, when elevator receives the instruction moved down, the castor of gate both sides in car folding process
61 are synchronously moved down by default vertical track 7, due to being in close contact with the corrugation bar 71 of vertical track 7 and frictional force is big, from
Lock construction remains open mode.When elevator moves down into designated layer, castor 61 contacts with driven pulley 81, castor 61 with
The engagement of driven pulley 81, castor 61 lose the active force of vertical track 7, start to reversely rotate, and cause to fix chain 62 relaxing, from
Lock shaft 63 loses fixed force, and is opened by the repulsive force of the magnet 64 at the both ends of self-locking shaft 63, unties self-locking structure, i.e. self-locking
Structure is closed, and the opening of driven pulley 81 and the auxiliary layer door of link gear 82 is driven while castor 61 reversely rotates,
During this, the door knife on gate will be clipped in the middle loaded on the door lock roller on layer door, and keep one with this two roller
Fixed gap, door motor driving gate machine, when door cutter holder, which lives door lock scroll wheel displacement, exceedes unlocking stroke, lock wall takes off with latch hook
From engagement, now unlock and complete, and layer door lock roller is moved by gate door knife-band and continues to cover whole door opening process.Afterwards again on
During moving or moving down, castor 61 is rapidly opened self-locking structure by vertical track 7, carries out self-locking, and so on.
The preferred embodiments of the present invention have shown and described in described above, as previously described, it should be understood that the present invention is not office
Be limited to form disclosed herein, be not to be taken as the exclusion to other embodiment, and available for various other combinations, modification and
Environment, and can be changed in the scope of the invention is set forth herein by the technology or knowledge of above-mentioned teaching or association area
It is dynamic., then all should be appended by the present invention and the change and change that those skilled in the art are carried out do not depart from the spirit and scope of the present invention
In scope of the claims.
