Abstract
The utility model relates to an elevator door knife which comprises a door knife bottom plate and two door blades which are arranged vertically and symmetrically on the front face of the door knife bottom plate. The door knife bottom plate is connected between lower portions of the symmetrical door blades through connection rod components of the door knife. The door knife bottom plate is connected between upper portions of the door blades through a swing arm component. The upper end of the swing arm component is movably connected with a transmission component which is arranged on the top of the back face of the door knife bottom plate. A door knife locking mechanism is arranged on the back face of the swing arm component. A guiding groove is arranged on the upper end portion of the swing arm component and matched with a guiding pulley which is fixedly arranged on the transmission component. The connection rod components and the swing arm component are connected with the door blades and the door knife bottom plate through bearings. Compared with the prior art, the elevator door knife has the advantages of being simple in structure, flexible in operation, high in safety coefficients, stable in operation, convenient to install, dismantle and maintain.
Description
Technical field
The utility model relates to a kind of elevator assemblies, relates in particular to a kind of elevator door knife.
Background technology
Along with the continuous construction of skyscraper, vertical lift elevator obtains using very widely.This vertical lift running velocity is fast, can carry cargo, and purposes is wide; In order to guarantee operation security, this elevator all is provided with Room door, improves the safety that the visitor takes advantage of personnel; Flexible in order to guarantee the hoistway door switch, this hoistway door all is by being arranged on the elevator door knife control Room door switch of elevator top.But, existing elevator door knife complicated structure, fault rate is higher, takes advantage of personnel that certain security implication is arranged to the visitor, occurs sometimes asynchrony phenomenon during door-opened elevator, and installation and maintenance are also relatively more difficult.。
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of running flexible, the elevator door knife that safety factor is high.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of elevator door knife, comprise that a cutter base plate and two vertically are arranged on the positive and symmetrical door blade of a cutter base plate, be flexibly connected by door cutter connecting rod assembly and door cutter base plate between the position under described two symmetrical door blades, be flexibly connected by swing arm unit and door cutter base plate between the upper part; Described swing arm unit upper end is flexibly connected with the transmission component that is arranged on a top, the cutter base plate back side.
In order to guarantee that elevator locks when the closure or openness, further, the described swing arm unit back side is provided with a cutter catch gear.
In order to pass through swing arm unit control gate cutter, more further, described swing arm unit upper-end part of driving is provided with guide groove, and this guide groove cooperates with track adjusting wheel on being fixedly installed on transmission component.
In order to realize that elevator door knife opens and closes freely, further, all be connected by bearing between described door cutter connecting rod assembly and swing arm unit and door blade and the cutter base plate.
Compared with prior art, usefulness of the present utility model is: this elevator door knife is simple in structure, running flexibly, safety factor is high, running is steadily installed, is dismantled and safeguard more convenient.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the utility model Facad structure schematic diagram;
Fig. 2 is the utility model structure schematic diagram.
Among the figure: 1, door cutter base plate; 2, door blade; 3, door cutter connecting rod assembly; 4, transmission component; 5, track adjusting wheel; 6, swing arm unit; 7, door cutter catch gear.
The specific embodiment:
Below in conjunction with the drawings and the specific embodiments the utility model is described in detail:
Fig. 1, a kind of elevator door knife shown in Figure 2, comprise that a cutter base plate 1 and two vertically are arranged on the positive and symmetrical door blade 2 of a cutter base plate 1, be flexibly connected by door cutter connecting rod assembly 3 and door cutter base plate 1 between described two symmetrical 2 times positions of door blade, be flexibly connected by swing arm unit 6 and door cutter base plate 1 between the upper part; Described swing arm unit 6 upper ends are flexibly connected with being arranged on a transmission component at top, cutter base plate 1 back side 4, are provided with track adjusting wheel 5 on the described transmission component 4, and track adjusting wheel 5 cooperates with the guide groove that is arranged on swing arm unit 6 upper-end part of drivings, the control elevator door switch; In order to make elevator door knife under the closure or openness state, keep locking, improve safety factor, described swing arm unit 6 back sides are provided with a cutter catch gear 7; All be connected by bearing between described door cutter connecting rod assembly 3 and swing arm unit 6 and door blade 2 and the cutter base plate 1, can improve hoistway door folding alerting ability.
Particularly, door blade 2 connects Room door, and when the croquet in being arranged on elevator entered between two door blades 2, door blade 2 was strutted, and the swing arm unit 6 that is arranged on a blade 2 upper parts drives transmission component 4 motions, and hoistway door is opened.Swing arm unit 6 drives 7 motions of door cutter catch gear simultaneously, realizes Room door locked; When closing, croquet separates with door blade 2, realizes closing the door of hoistway doors by transmission component 4, and simultaneously, a door cutter catch gear 7 improves safety factor with the elevator door locking.
This elevator door knife is simple in structure, running flexibly, safety factor is high, running is steadily installed, is dismantled and safeguard more convenient.
It is emphasized that: above only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does.
