Abstract
The invention discloses a synchronous belt elevator door knife which is provided with a synchronous belt; the upper half part of the synchronous belt is provided with a main door knife, and the lower half part of the synchronous belt is provided with an auxiliary door knife; the main door knife comprises a main door knife bottom plate and two symmetrical main door blades which are arranged at the front of the main door knife bottom plate, and the main door blades are movably connected with the main door knife bottom plate by two main door knife connecting rod components arranged up and down in parallel; a transmission gear connected with the synchronous belt is arranged between the main door knife bottom plate and the main door knife connecting rod component arranged at the upper end of the main door knife; another transmission gear connected with the synchronous belt is arranged in the middle part of the front of the auxiliary door knife; the back of the main door knife bottom plate is provided with a main door knife locking mechanism connected with the transmission gear; and the back of the auxiliary door knife is provided with an auxiliary door knife locking mechanism connected with the transmission gear. The synchronous belt elevator door knife has the advantages of being flexible in operation, high in safety factor, wide in adaptability, more convenient to install, disassemble and maintain and lower in cost.
Description
Technical field
The present invention relates to a kind of lift appliance, relate in particular to a kind of synchronous band elevator door cutter.
Background technology
Elevator is essential in existing high level or heavy construction, and particularly the utilization cage lifter is more extensive in the skyscraper.Continuous development along with elevator technology; The elevator of more and more styles is used in fields such as buildings; In order to guarantee that the elevator visitor takes advantage of personnel's safety; The designer imports and exports to be provided with at elevator hoistway door has been installed, and can open and close flexibly in order to guarantee hoistway door, and these hoistway doors are realized driving through the elevator door cutter mostly.Mostly general elevator door cutter is the simple gate cutter, operates slowlyer, and fault rate is than higher; Installing/dismounting and safeguard relatively difficulty operates dumbly, takes advantage of personnel to produce certain influence to the elevator visitor; And for the double door elevator, this simple gate cutter mechanism is inapplicable again.
Summary of the invention
Technical matters to be solved by this invention is, provides a kind of and operates flexibly, safety factor is high and the synchronous band elevator door cutter of wide adaptability.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of synchronous band elevator door cutter, have synchronous band, and said synchronous band the first half is provided with main door cutter, and the latter half is provided with secondary door cutter; Said main door cutter by main door cutter base plate be arranged on positive last two the symmetrical main door blades of main door cutter base plate and constitute, and should master door blade by two main door cutter link assemblies and main cutter base plates flexible connection that are set up in parallel up and down.
In order to control the running of main door cutter, further, be provided with between the main door cutter connecting rod assembly of said main door cutter upper end and the main door cutter base plate and be connected the synchronous transmission gear of being with.
In order to control the running of secondary door cutter, further, the positive middle part of said secondary door cutter is provided with and connects the transmission gear of band synchronously.
In order to guarantee that when state is closed in switching hoistway door does not operate, more further, the said main door cutter base plate back side is provided with and said transmission gear bonded assembly master door cutter catch gear.
In order to guarantee that when state is closed in switching hoistway door does not operate, further, said secondary door knife back face is provided with and the secondary door of said transmission gear bonded assembly cutter catch gear.
Compared with prior art, usefulness of the present invention is: this synchronous band elevator door cutter running flexibly, safety factor is high, wide adaptability is installed, dismantles and safeguard more convenient, cost is lower.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is a Facad structure scheme drawing of the present invention;
Fig. 2 is a structure scheme drawing of the present invention.
Among the figure: 1, main door cutter; 11, main door cutter base plate; 12, main door blade; 13, main door cutter connecting rod assembly; 14, transmission gear; 2, secondary door cutter; 21, transmission gear; 3, be with synchronously; 4, main door cutter catch gear; 5, secondary door cutter catch gear.
The specific embodiment:
Describe the present invention below in conjunction with the accompanying drawing and the specific embodiment:
Fig. 1, a kind of synchronous band elevator door cutter shown in Figure 2 have and are with 3 synchronously, and said 3 the first half of being with synchronously are provided with main door cutter 1, and the latter half is provided with secondary door cutter 2; Said main door cutter 1 by main door cutter base plate 11 be arranged on main door cutter base plate 11 positive last two symmetrical main door blades 12 and constitute, and should master door blade 12 by two main door cutter connecting rod assemblies 13 that are set up in parallel and main cutter base plates 11 flexible connections up and down; Be provided with the transmission gear 14 that is connected synchronously with 3 between the main door cutter connecting rod assembly 13 of said main door cutter 1 upper end and main the cutter base plate 11; Said secondary door cutter 2 positive middle parts are provided with connection synchronously with 3 transmission gear 21; In order to improve safety, said main door cutter base plate 11 is respectively arranged with the main door cutter catch gear 4 and secondary door cutter catch gear 5 that is connected transmission gear 14 and transmission gear 21 with secondary door cutter 2 back sides.
Its function mode is following; Driving transmission gear 14 when being with 3 runnings synchronously rotates with transmission gear 21; Transmission gear 14 drives 13 activities of main door cutter connecting rod assembly; Drive 12 activities of main door blade through main door cutter connecting rod assembly 13, transmission gear 14 drives main door cutter catch gear 4 and 5 runnings of secondary door cutter catch gear respectively with transmission gear 21 simultaneously, realizes the unlatching and closed and locking of elevator door.
This synchronous band elevator door cutter running flexibly, safety factor is high, wide adaptability is installed, dismantles and safeguard more convenient, cost is lower.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
