Description
Technical field
The present invention relates to lift appliance field, particularly a kind of three-blade type anti-theft door vane.
Background technology
The car door lock of current elevator is not also standard configuration.When elevator stops, if its car door sill is higher than more than lading door dill 900mm, passenger pushs gate aside at cab interior, can open Room door and leave car, now there is the risk that passenger falls from space between lading door dill and toe guard of elevator car from cab interior.
Prevent that taking off a cutter can prevent passenger from pushing gate aside at non-flat layer region, avoids the equivalent risk that falls.Existing door cutter technology, car door lock increases by one at Room reveal to unlock croquet or a trip lever, can prevent from opening gate at cab interior; Part is anti-, and to take off a cutter be inconsistent by the height of door blade when opening and clamp, then increase by two fixing limiting brackets, thus reach and prevent taking off effect.
In existing door cutter technology, the anti-cutter of taking off of gate locking-type increases croquet or trip lever due to needs at every layer of Room reveal, adds great amount of cost; Or utilize inconsistent anti-of height when opening and clamp to take off a cutter, due to its structural limitations, two blades must be arranged to independently structure, thus reduce service life, add failure risk, and damage can be caused by easy opposite house blade at abnormal condition bottom band door.

Accompanying drawing explanation
The accompanying drawing forming a part of the present invention is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 shows the schematic diagram of an embodiment of three-blade type anti-theft door vane of the present invention;
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
Three-blade type anti-theft door vane of the present invention is at the three film gate blade compositions by being fixed on elevator box, door cutter base plate 16 is fixed on the gantry crane plate 9 of elevator, driving band 18 is fastened on gantry crane plate 9, as shown be a cutter open configuration, the left-hand door ball 12 be now fixed on floor is arranged in the centre of left-hand door blade 15 and door blade 27, be fixed on right croquet 23 on floor between middle door blade 27 and right door blade 30, lift crank 8 is increased to the highest point of guiding trestle 3 by lifting rod 5, is in open configuration all the time to keep a cutter.When anti-support 19 of taking off is taken off when pin 20 is in engagement can not push gate aside at non-flat layer region with anti-.
Anti-functional module of taking off a cutter describes:
Transmission module: drive belt 18 is fixed on gantry crane plate 9, drags gantry crane plate 9 and door knife assembly moves back and forth on door machine guide rail.
Lift module: position-limited wheel 2 and position-limited wheel 6 are separately fixed on left socle 1 and right support 7, and left socle 1 and right support 7 are separately fixed on gantry crane plate 9; Guiding trestle 3 is fixed on a machine body 31, and lift wheel 4 moves along guiding trestle 3, and lifting rod 5 moves up and down along the long lumbar hole of position-limited wheel 2 and position-limited wheel 6 and lift crank 8.Lift crank 8 is increased to the highest point of guiding trestle 3 by lifting rod 5, is in open configuration all the time to keep a cutter.
Prevent taking off module: middle door blade 27 is around the first crank 10 and the second crank 14 up-and-down movement be fixed on a cutter base plate 16, when door cutter opens, middle door blade 27 is moved downward by deadweight and left spring 13, and located by the locating dowel pin 11 be fixed on a cutter base plate 16, in now connecting, door blade 27 anti-takes off support 19 and is self-locking in be fixed on a machine body 31 anti-and takes off pin 20; When door cutter closes, if left-hand door ball is at perch, then pass through to push left-hand door ball 12 to middle door blade 27 towards the motion of left-hand door ball 12, in also driving after contacting, door blade 27 upwards does circular motion, thus disengagement is prevented taking off pin 20.
Door cutter closes self-locking module: starter cup 25 is fixed on pivot arm 21, before door cutter opens, starter cup 25 contacts with the fixed support 24 be fixed on a machine body 31 and makes pivot arm 21 clickwise that is fixed on right door blade 30, thus pivot arm 21 throws off the self-lock pin 22 be fixed on a cutter base plate 16, door cutter side opens; When gantry crane plate 9 is to left movement, now door cutter progressively closes, and pivot arm 21 makes pivot arm 21 left-hand revolution by extension spring 26 and deadweight, pivot arm 21 and self-lock pin 22 locking when door cutter is completely closed.
Door cutter clamping croquet way: anti-ly take off the unlatching that module and door cutter close self-locking module and need ensure that size A=size B+ intermediate door cutter 27 unlocks desirable value, the horizontal throw that left-hand door ball 12 moves right=size B+ intermediate door cutter 27 unlocks desirable value, right croquet 23 can be moved to the left, and the horizontal throw of its movement is B value.As above requiring under size, can guarantee that when door cutter closes left-hand door blade 15 and middle door blade 27 clamp left-hand door ball, right door blade 30 and middle door blade 27 clamp right croquet 23 simultaneously.
As shown be a cutter open configuration, namely door is in closed condition, lift module is driven to make a cutter be in open configuration all the time by transmission module, left-hand door ball 12 and right croquet 23 lay respectively at left-hand door blade 15 simultaneously, middle door blade 27, between right door blade 30, make to prevent that taking off module is in locking states, separate the locking that door opening knife closes self-locking module simultaneously.Now, at non-flat layer state by preventing that taking off module can not push gate aside, when elevator is in flat bed state, left-hand door ball 12 and right croquet 23 are between three film gate cuttves, now push gate aside, gantry crane plate 9, to left movement, makes middle door blade 27 contact left-hand door ball 12, and raised by left-hand door ball 12, thus untie anti-module of taking off and open gate.When using triangular key to open from Room door, left-hand door ball 12 moves to intermediate door cutter 27, and is raised by middle door blade 27, thus unties anti-module of taking off and open gate.
When gate needs to open, transmission module makes gantry crane plate 9 to left movement, makes middle door blade 27 contact left-hand door ball 12, and is raised by left-hand door ball 12, thus unties anti-module of taking off and open gate.
Croquet way is stepped up by door cutter, can make elevator enabling and at closing time guarantee door cutter before starting to open, ensure that gate is consistent with Room door run, and the power of closing gate and Room door is divided equally on left-hand door blade 15 and middle door blade 27, the power of opening gate and Room door is divided equally on middle door blade 27 and right door blade 30.
According to three-blade type anti-theft door vane of the present invention, there is following beneficial effect:
First, it is simple that this prevents pulling out a knife structure, handling ease, is convenient to control;
Secondly, without the need to increasing any parts at Room reveal;
Again, when switch gate, Room door, croquet is in synchronous regime all the time before door cutter opens;
Finally, when closing and open gate, Room door, its driving force is transformed into respectively on two door blades, increases service life.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
