Abstract
The invention discloses a fireproof structure of an elevator landing door. The fireproof structure comprises an elevator door plate and a sill, wherein at least two grooves are formed in the sill in parallel, a raised guide rail is arranged between two adjacent grooves, and the guide rail continuously extends in the door opening and closing direction of the elevator door plate; a guide groove which is matched with the guide rail is formed in the lower end of the elevator door plate, the portions, on two sides of the guide groove, of the lower end of the elevator door plate are respectively embedded into the grooves in both sides of the guide rail of the sill, and a guide part which is matched with the guide rail is arranged in the guide groove. According to the fireproof structure, the raised guide rail is arranged between the bottoms of the grooves of the sill, the guide part which is matched with the guide rail is arranged in the door plate, the guide rail is used for guiding the door plate and preventing the door plate from falling off, and additionally, the both sides of the lower end of the door plate are integrally embedded into the grooves of the sill, so that the fireproof performance of the door plate is improved, and the integral strength and anti-unhooking capability of an elevator door system are increased.
Description
Technical field
The present invention relates to the layer door and the fire proof construction of sill of lifting type elevator technical field, especially elevator.
Background technology
Elevator cage is acted on carrying, while groove is offered above, for the guiding of door-plate.CNS
《GB-T 7588-2003 elevators are manufactured and install safety standard》The intensity of elevator car door system is required（Need to clash into examination
Test）, while needing a device to prevent door-plate under external force from departing from sill groove.In addition, as Fireproof elevator layer
Door, in addition to function above, must be requested that reach fire protection requirement.General elevator door fire proof construction is slided in door-plate bottom
Increase fireguard between block, to reach the purpose for preventing fire from stretching.As shown in figure 1, the bottom of door-plate 1 is except being provided with door
Slide block 11 is slidingly fitted with the groove 21 of sill 2, is additionally provided with fire resisting shield 12, and the lower edge of fire resisting shield 12 enters ground
In the groove 21 of bank 2.
The shortcoming of the elevator door fire proof construction of prior art is yet suffered between many between elevator door 1 and sill 2
Gap, for example gap 22,23,24,25, cause flameproof effect not good, and elevator door 1 is also easy to depart from sill 2.
The content of the invention
In view of this, it is an object of the invention to provide a kind of structural strength is higher, flameproof effect is more preferably and with preventing layer
Door departs from the elevator door fire proof construction of the anticreep effect of sill.
To reach above-mentioned purpose, the present invention is employed the following technical solutions：
A kind of elevator door fire proof construction, including door of elevator and sill, it is characterised in that：Offer side by side on the sill to
Few two grooves, have raised guided way between the two neighboring groove, the guided way is opened along the door of elevator
Direction of closing the door continuously extends；The bottom of the door of elevator offers the gathering sill being engaged with the guided way, the electricity
The bottom of terraced door-plate is respectively embedded into the sill in the groove of the guided way both sides in the both sides of the gathering sill,
The guide coordinated with the guided way is provided with the gathering sill.
Preferably, the guide coordinates rolling support on the surface of the guided way.
In some specific embodiments, multiple described guides are arranged at intervals with the gathering sill.
Preferably, the guide is guide roller, and the guide roller is arranged on described leading around itself axial rotation
To in groove.
In some specific embodiments, the length extension side for itself being axially perpendicular to the gathering sill of the guide roller
To.
The elevator door fire proof construction that the present invention is provided, using the elevator cage with particular channel, in the groove of sill
There is the guided way of a projection in the middle of bottom, both the guiding as door-plate, and the anticreep as door-plate, meanwhile, the lower end of door-plate
The both sides in portion are integrally embedded in the groove of sill, have so both improved door-plate fire protecting performance, while and increased elevator car door system
Bulk strength and mousing-hook ability.
Description of the drawings
Fig. 1 is the perspective diagram of the elevator door fire proof construction of prior art.
Fig. 2 is the cross-sectional view of the elevator door fire proof construction of embodiment.
Fig. 3 is the A-A profiles of Fig. 2.
Specific embodiment
The specific embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.
Fig. 2 and Fig. 3, a kind of elevator door fire proof construction of the present embodiment, including door of elevator 10 and sill 20 are referred to,
Offer at least two grooves 210 on sill 20 side by side, there is raised guided way 220 between two neighboring groove 210, be oriented to
Rail 220 continuously extends along the switch gate direction of door of elevator 10, in the present embodiment the switch gate direction of door of elevator 10 i.e. along
The left and right directions of the paper of Fig. 2.
The bottom of door of elevator 10 offers the gathering sill 110 being engaged with guided way 220, the lower end of door of elevator 10
Portion is respectively embedded into sill 20 in the groove 210 of the both sides of guided way 220 in the both sides of gathering sill 110, be provided with gathering sill 110 with
The guide 30 that guided way 220 coordinates.In the present embodiment, guide 30 coordinates rolling support on the surface 221 of guided way 220
On.In order to increase stability, multiple guides 30 are arranged at intervals with gathering sill 110.In the present embodiment, guide 30 is guiding
Roller, the guide roller is arranged in gathering sill 110 around itself axial rotation.In the present embodiment, the guide roller
Itself it is axially perpendicular to the length bearing of trend of gathering sill 110.
Because the both sides of the bottom of door of elevator 10 are respectively embedded in the groove 210 of sill 20, the guided way of sill 20
220 are engaged with the gathering sill 110 of door of elevator 10, and be additionally provided with door of elevator 10 with guided way 220 mutually roll coordinate
Guide 30, therefore, the elevator door fire proof construction of the present embodiment has that structural strength is higher, flameproof effect more preferably and anticreep is imitated
The more preferable advantage of fruit.
Above-described embodiment technology design only to illustrate the invention and feature, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implement according to this, can not be limited the scope of the invention with this, all according to the present invention
Equivalence changes or modification that Spirit Essence is made, all should be included within the scope of the present invention.
