Abstract
The invention discloses a landing sill device for an elevator. The landing sill device comprises a landing sill and a sill bracket arranged at the lower part of the landing sill, wherein a disconnecting prevention groove which can be matched with the lower end structure of a landing door of the elevator and can enable the lower end structure of the landing door to slide thereon is arranged at the middle part of the landing sill, two free ends of the sill bracket are bent upward and respectively form side supporting frames, the upper ends of the side supporting frames are fixed with the two ends of the landing sill through welding, a middle part reinforcing supporting frame arranged between the landing sill and the sill bracket is arranged on the side surface of the disconnecting prevention groove, and the upper and lower ends of the middle part reinforcing supporting frame are respectively fixed with the lower side surface of the landing sill and the upper side surface of the sill bracket through welding. The landing sill device for the elevator guarantees safety of the elevator, and a middle part reinforcing structure and multiple fastening bolt connecting pieces are arranged, so that stability of an overall structure is enhanced, and the landing sill device for the elevator can be applicable to various elevators and has high structural safety and good running stability.
Description
Technical field:
The present invention relates to a kind of landing-door sill device of elevator.
Background technology:
When lift car is positioned at other stops or gate is closed, layer door is being kept closed, which ensure that people, other animals or object can not enter elevator hoistways, avoid the accident of meeting accident, and for general elevator, its landing-door sill device does not have hook groove, this sill component can ensure layer door when switch gate by certain orbital motion, but, if layer door is when being subject to external force collision, will be easy to deform and depart from sill, thus people is caused, other animals or object just likely can be strayed into hoistway and meet accident, there is larger potential safety hazard.
Summary of the invention:
The technical problem to be solved in the present invention is to provide that a kind of safety is high, good stability and can effectively avoid layer door not depart from the landing-door sill device of sill when being subject to clashing into.
For solving the problem, the present invention is achieved by the following technical solutions:
A kind of landing-door sill device of elevator, there is landing sill and be arranged at the ground sill bracket of landing sill bottom, in the middle part of described landing sill, be provided with one can make with elevator door bottom respective outer side edges the anticreep groove that layer door bottom structure is slided thereon, described ground sill bracket two free end upwards bending also forms side supports frame respectively, the described upper end of side supports frame and the both ends of landing sill are welded and fixed, be provided with a middle part be placed between landing sill and ground sill bracket in the side of described anticreep groove and strengthen bracing frame, the two ends up and down that bracing frame is strengthened at described middle part are welded and fixed with the downside of landing sill and the upper side of ground sill bracket respectively.
As preferably, described ground sill bracket is provided with the strip shape opening passed for bolt shank, and described strip shape opening is placed in immediately below anticreep groove.
As preferably, described strip shape opening is provided with multiple stair-stepping circular hole by spacing, described landing sill is connected and fixed by bolt between circular hole and ground sill bracket.
As preferably, the side supports frame of described sill bracket side and horizontal plane.
As preferably, strengthen at described middle part between bracing frame and side supports frame, being provided with the clamp nut that passes ground sill bracket.
Compared with prior art, usefulness of the present invention is: the landing-door sill device of this elevator adds hook groove on landing sill, with the layer door of lower end buckle with the use of, layer door can be made not depart from sill when being subject to clashing into, ensure the safety of elevator, and be provided with middle part reinforcement structure and multiple binding bolt attaching parts, thus more enhance integrally-built steadiness, and multiple elevator can be applicable to, its safety of structure is high, applied widely, good operation stability.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described:
Fig. 1 is Facad structure schematic diagram of the present invention
In figure: 1, landing sill 2, sill bracket 21, side supports frame 3, anticreep groove 4, middle part strengthen bracing frame 5, circular hole 6, clamp nut
Detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
The landing-door sill device of a kind of elevator of the present invention, as shown in Figure 1, there is landing sill 1 and be arranged at the ground sill bracket 2 of landing sill 1 bottom, in the middle part of described landing sill 1, be provided with one can make with elevator door 1 bottom respective outer side edges the anticreep groove that layer door bottom structure is slided thereon, described ground sill bracket 2 liang of free ends upwards bending also form side supports frame 21 respectively, the upper end of described side supports frame 21 and the both ends of landing sill 1 are welded and fixed, be provided with a middle part being placed in landing sill 1 and ground sill bracket 2 support in the side of described anticreep groove 3 and strengthen bracing frame 4, the two ends up and down that bracing frame 4 is strengthened at described middle part are welded and fixed with the downside of landing sill 1 and the upper side of ground sill bracket 2 respectively.Sill bracket 2 inside, ground is placed in for convenience of bolt and nut being connected fastener, described ground sill bracket 2 is provided with the strip shape opening passed for bolt shank, described strip shape opening is placed in immediately below anticreep groove 3, thus when practical application, only need by the bar portion of the described bolt with nut through strip shape opening, then bolts and nuts are tightened fixing, thus described ground sill bracket 2 and landing sill 1 are fixed.
Ask steadiness for strengthening ground sill bracket 2 with being connected between landing sill 1, described strip shape opening be provided with multiple stair-stepping circular hole 5 by spacing, described landing sill 1 by circular hole 5 and between sill bracket 2 bolt be connected and fixed.In addition, for strengthening integrally-built steadiness, the side supports frame 21 of described ground sill bracket 2 side and horizontal plane.Strengthen at described middle part between bracing frame 4 and side supports frame 21, being provided with the clamp nut 6 that passes ground sill bracket 2.
The landing-door sill device of above-mentioned elevator adds hook groove on landing sill, with the layer door of lower end buckle with the use of, layer door can be made not depart from sill when being subject to clashing into, ensure the safety of elevator, and be provided with middle part reinforcement structure and multiple binding bolt attaching parts, thus more enhance integrally-built steadiness, and multiple elevator can be applicable to, its safety of structure is high, applied widely, good operation stability.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
