Abstract
The invention relates to a center opening door bottom plate for a disengaging prevention elevator. The center opening door bottom plate is characterized in that a guide rail is manufactured on a bottom plate body in the length direction of the bottom plate body, and the guide rail is bent to form an arc-shaped upper guide rail face and an arc-shaped lower guide rail face; and an upper guide groove is formed between the arc-shaped upper guide rail face and the bottom plate, a lower guide groove is formed between the arc-shaped lower guide rail face and the bottom plate, the upper guide groove is bent and is an arc-shaped upper guide groove, and the lower guide groove is bent and is an arc-shaped lower guide groove. The center opening door bottom plate is scientific and reasonable in structural design, the bent arc-shaped up-down double-rail structure is adopted, machining is easy, machining convenience is improved, meanwhile in cooperation with an upper disengaging prevention hanging plate and a lower disengaging prevention hanging plate, and the center opening door bottom plate for the disengaging prevention elevator has the beneficial effects of being steady in structure, high in reliability good in disengaging prevention effect and quite high in innovativeness.
Description
Technical field
The invention belongs to elevator technology field, particularly a kind of anticreep elevator center opening door head base plate.
Background technology
The composition of elevator fire resistant doorsets includes: fireproof landing door device, fireproof door plate, fire prevention door pocket, anti-
Fire sill etc.；Its main door-opening mode mainly has: in point, side open two-fold, in point two-fold etc.,
Common for midsplit type.Elevator fire resistant doorsets, in addition to the function possessing common door, are also equipped with preventing floor
Fire is spread by elevator hoistways most important effect.By between door-plate, door pocket and sill
All be mutually twisted by special structure, with flow of metal after keeping from heat excessive and produce bigger seam
Gap, and its integrity can be kept after being heated, it is possible to bear corresponding power.For midsplit type
Fire resistant doorsets, its head unit is made up of base plate and two link plates of band guide rail, is divided by two link plates
Dai Dong not move by two door-plates.Its guide rail uses the mode of bending on base plate to make guide rail.
The guide wheel installed on link plate moves along guide rail upper surface.For ensureing the stable of link plate and base plate
Property, on link plate, generally make mousing-hook, existing mousing-hook all hangs over edge on guide rail, and bottom does not has
There is disconnecting prevention structure.And, its guide rail bending of existing base plate require formed approximation right angle, therefore its
Difficulty of processing is relatively big, if forming arc-shaped rail, have the most again that anticreep public affairs function is difficult to ensure that asks
Topic.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that one is prone to processing, it is ensured that
The anticreep elevator center opening door head base plate of anticreep reliability between link plate and base plate.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of anticreep elevator center opening door head base plate, it is characterised in that: on base plate along its length
Being shaped with guide rail, this guide rail forms circular arc upper rail face and circular arc lower guideway face through bending；Described
Circular arc upper rail face and circular arc lower guideway face and respectively and form upper rail between base plate respectively
And lower guide channel, the circular arc upper rail that described upper rail is also formed for bending, lower guide channel is bending
The circular arc lower guide channel formed.
And, described base plate top fold is shaped with the level fire prevention edge of downward flange.
Advantages of the present invention and having the beneficial effect that
1, this anticreep elevator center opening door head base plate, guide rail be through bending formed circular arc upper rail face and
Circular arc lower guideway face；The circular arc upper rail that upper rail is also formed for bending, lower guide channel is bending
The circular arc lower guide channel formed, it can coordinate with the upper and lower mousing-hook on link plate, forms anticreep knot
Structure, and there is the advantage being prone to processing, it is to avoid original bending technique difficulty is big, and behind formation right angle
The problem that the sheet material stress caused is concentrated.
2, this anticreep elevator center opening door head base plate, base plate top fold is shaped with the level of downward flange to be prevented
Fire edge, opposite house head unit plays protective action, improves fire protecting performance.
3, present configuration design science is reasonable, uses the upper and lower double-rail configuration of circular arc bending,
It is not only easy to processing, improves easy making process, upper and lower pair of anticreep link plate can be coordinated simultaneously, have
Stabilized structure, reliability is high, the advantage of good anti-drop effect, is a kind of to have the anti-of higher innovation
De-elevator center opening door head base plate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the schematic cross-section (coordinating with link plate) of the present invention.
Description of reference numerals:
Lead on 1-base plate, 2-level fire prevention edge, 3-guide rail, 4-upper rail face, 5-lower guideway face, 6-
Mousing-hook under groove, 7-lower guide channel, 8-link plate, 9-guide wheel, the upper mousing-hook of 10-, 11-.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings, and following example are illustrative, no
It is determinate, it is impossible to limit protection scope of the present invention with this.
A kind of anticreep elevator center opening door head base plate, it is shaped with guide rail 3 on base plate 1 along its length,
This guide rail forms circular arc upper rail face 4 and circular arc lower guideway face 5 through bending.Circular arc upper rail
Face and circular arc lower guideway face and respectively and between base plate, form upper rail 6 and lower guide channel 7 respectively, on
The circular arc upper rail that guide groove is also formed for bending, lower guide channel is the circular arc lower guide channel that bending is formed.
It can coordinate with the upper mousing-hook 10 on link plate 8, lower mousing-hook 11, forms upper and lower pair of anticreep knot
Structure.The guide wheel 9 installed on link plate guides the circular arc upper rail face running on guide rail.Base plate has
There is the advantage being prone to processing, it is to avoid original bending technique difficulty is big, and caused behind formation right angle
The problem that sheet material stress is concentrated.
Base plate top fold is shaped with the level of downward flange and prevents fires along 2.Opposite house head unit plays protection and makees
With, improve fire protecting performance.
Although disclosed embodiments of the invention and accompanying drawing for the purpose of illustration, but the technology of this area
Personnel are appreciated that without departing from the present invention and spirit and scope of the appended claims, various
Replace, to change and modifications be all possible, and therefore the scope of the present invention is not limited to embodiment and attached
Figure disclosure of that.
