Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
In conjunction with shown in Fig. 2 to Fig. 5, the suspension assembly of elevator door of the invention, including guide part are schematically showed
Part 1 and door hang component 2, and guiding parts 1 is fixedly connected on the top of door opening, and door hangs the top that component 2 is located at elevator door.
Such as Fig. 3, guiding parts 1 is equipped with guide rail 11 and guide groove 12, and guide rail 11 is located at the top of guide groove 12.Guide groove 12 is opened
Mouth 121 is arranged against the inside of elevator shaft, and an inner sidewall of guide groove 12 is equipped with the flange towards the bending of the middle part of opening 121
122, another inner sidewall is equipped with block piece 13, and specifically, the U-shaped profile of guide groove 12, block piece 13 is arranged in guide groove
Middle part on 12 length direction.
Such as Fig. 4, door hangs component 2 and is equipped with door change gear 21 and anticreep wheel 22, and door change gear 21 is located at the top of anticreep wheel 22, and
The axis of the two is arranged in parallel.Such as Fig. 2, door change gear 21 is actively cooperatively connected in guide rail 11, and anticreep wheel 22 is actively embedded at
In guide groove 12, anticreep wheel 22 rolls on one of inner sidewall of guide groove 12, to ensure that a change gear 21 can tightly cooperate
Be connected to guide rail 11, avoid elevator operate normally when occur door change gear 21 derail, specifically, block piece 13 be located at and
On the inner sidewall of the connected guide groove 12 of anticreep wheel 22.The inside of flange 122 and the end face of anticreep wheel 22 are oppositely arranged, the flange
122 can prevent anticreep wheel 22 from deviating from from guide groove 12, and the flange 122 that unilateral side is arranged in guide groove 12 is also convenient for assembly crewman and will prevent
In de- 22 insertion guide groove 12 of wheel, if the two sides of guide groove 12 are respectively provided with flange 122, anticreep wheel 22 needs embedding from the both ends of guide groove 12
Enter in guide groove 12, is not easy to assemble.When elevator door is closed, the end face of anticreep wheel 22 is oppositely arranged or offsets with block piece 13
It connects, therefore in pendulum impact test, the end face of anticreep wheel 22 is hit and is connected on block piece 13 and flange 122 simultaneously, hinders
Block piece 13 and flange 122 can ensure that 22 uniform force of anticreep wheel, and the shaft 221 of anticreep wheel 22 is only drawn in its axial direction
Power avoids 221 bending deformation of shaft of anticreep wheel 22 and causes elevator door stuck.
Further, the excircle of door change gear 21 is equipped with groove 211, i.e. the cross section of the tyre tread of door change gear 21 is C-shaped, leads
The shape of rail 11 and the shape of groove 211 match, and guide rail 11 is actively cooperatively connected towards its top protrusion, groove 211 in leading
Rail 11, door change gear 21 is independently oriented to ensure a change gear 21 rotation when matched always with guide rail 11, anti-anti-avulsion
Rail.For the quiet property of the operation of lever gear door change gear 21 and protective door change gear 21 is worn to avoid it, on the bottom wall of groove 211
Equipped with polyurethane wear resistant layer 213.
The limiting slot 14 positioned at the side of guide rail 11, specifically, limiting slot 14 and lift car are additionally provided on guiding parts 1
It is located at the two sides of guide rail 11.Corresponding, the end face of door change gear 21 is equipped with anti-decylization 212, and the outer diameter of anti-decylization 212 is greater than
The outer diameter of door change gear 21, protrudes into anti-decylization 212 in limiting slot 14, a change gear 21 is further prevented to deviate from from guide rail 11.This
Outside, the ontology of guide rail 11 and guiding parts 1 is located at the two sides of limiting slot 14, this makes limiting slot 14 and guiding parts 1
Ontology change gear 21 can be limited on the door: as shown in Fig. 2, when door change gear 21 deviates from the ontology of guiding parts 1 along its axial direction
When movement, the end face of anti-decylization 212 is connected to the inner sidewall of limiting slot 14 and is limited with change gear 21 on the door, and works as door change gear 21
When moving along it axially towards the ontology of guiding parts 1, the end face (or anti-decylization 212) of door change gear 21 can be connected to guiding parts
1 ontology.Wherein, between the outer rim of anti-decylization 212 and the bottom wall of limiting slot 14 have gap, when polyurethane wear resistant layer 213 still
When not wearing, the thickness in above-mentioned gap should be greater than the thickness of polyurethane wear resistant layer 213, so that wearing in polyurethane wear resistant layer 213
After, the outer rim of anticreep wheel 22 still will not be connected on the bottom wall of limiting slot 14.
It is integrated to enhance the rigidity of the component, guide rail 11 and guide groove 12 and guiding parts 1, block piece 13
For screw, the inner sidewall of guide groove 12 is equipped with threaded hole, and screw screws in screw hole.
Such as Fig. 5, door is hung and offers slotted hole 23 on component 2, the extending direction of slotted hole 23 and the extending direction of guide groove 12
It is obliquely installed, the shaft 221 of anticreep wheel 22 penetrates slotted hole 23, adjusts position of the shaft 221 of anticreep wheel 22 in slotted hole 23
Set the bonding tightness that the inner sidewall of anticreep wheel 22 and guide groove 12 can be adjusted.Door change gear 21, anticreep wheel 22 and block piece 13
Quantity is equipped with multiple, and the quantity of anticreep wheel 22 is consistent with the quantity of block piece 13.
In conclusion the suspension assembly of elevator door of the invention, change gear 21 is actively cooperatively connected in guide rail 11,
Elevator door being hung on guide rail 11 to and be ensured, elevator door can slide on guide rail 11, anticreep wheel 22 is then actively embedding
In guide groove 12, an inner sidewall of guide groove 12 is equipped with flange 122, another inner sidewall is equipped with block piece 13, flange
122 inside and the end face of anticreep wheel 22 are oppositely arranged, and can prevent anticreep wheel 22 from deviating from from guide groove 12, while guide groove 12 is unilateral
The flange 122 of setting is also convenient for anticreep wheel 22 and is embedded in guide groove 12, when elevator door is closed, the end of block piece 13 and anticreep wheel 22
Face is oppositely arranged or abuts against, and further prevents anticreep wheel 22 to deviate from from guide groove 12, and in pendulum impact test, anticreep wheel
22 end face is connected on block piece 13 and flange 122 simultaneously, so that 22 uniform force of anticreep wheel, avoids the occurrence of anticreep wheel 22
The case where 221 bending deformation of shaft.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and replacement can also be made, these are improved and replacement
Also it should be regarded as protection scope of the present invention.
