According to the anti-falling type elevator landing door device disclosed by the invention, the problem that landing door hanging plates on a traditional elevator landing door device are easy to fall off is solved.
Description
Technical field
The present invention relates to a kind of elevator landing door, especially a kind of can the effective run-resistant elevator landing door that comes off of preventing layer door strap, belong to elevator technology field.
Background technology
Elevator landing door is the important component part of Lift car type elevator, it comprises bank and is arranged on the layer door hanging plate of about two pieces distributions on door opener outside bank, layer door hanging plate can horizontally slip, and fixes bottom layer door hanging plate with corresponding elevator door, for driving elevator door folding.
But, for the door opening machine for elevator of conventional confguration, if when loosening or damaging appears in its link plate, probably cause the overall landing of link plate, and cause danger.
Summary of the invention
The present invention seeks to: a kind of run-resistant elevator landing door is provided, be intended to solve the problem that on traditional elevator layer door gear, layer door hanging plate easily comes off.
Technical scheme of the present invention is: a kind of run-resistant elevator landing door, comprise bank, be horizontally placed on line slide rail on this on bank, to be connected on described line slide rail by roller and can the layer door hanging plate of parallel motion, described upper bank is also provided with the anticreep track that horizontal linear extends, on described layer door hanging plate, rotary connection has the gear wheel be arranged in described anticreep track, and the arranged outside of described anticreep track has upwards extension and keeps off inside described gear wheel, with the anticreep side block limit stoping gear wheel to depart from anticreep track.
The present invention, on the basis of technique scheme, also comprises following preferred version:
The top of described line slide rail, with the straight-line groove of a linearly rail length directional spreding, described layer door hanging plate is provided with and stretches in described straight-line groove and can along the anti-drop hook of this straight-line groove horizontal slip.
Described layer door hanging plate is provided with two described anti-drop hooks, and these two anti-drop hook horizontal interval (HI) distributions.
Described line slide rail, anticreep track, anticreep side block limit and Shang Kan are structure as a whole.
Described anticreep track is positioned at the below of described line slide rail, and described gear wheel is positioned at the below of described anti-drop hook.
Described upper bank forms and is positioned at above described gear wheel, with rib on the anticreep stoping gear wheel to move up.
Described gear wheel to be arranged on described anticreep between rib and anticreep track.
Advantage of the present invention is: in use, will depart from from upper bank once layer door hanging plate because loosening or damage, the anti-drop hook of layer door hanging plate sidepiece just can be stuck in the straight-line groove on line slide rail top this elevator landing door of the present invention.Meanwhile, the anticreep side block limit on upper bank outside the anticreep track also gear wheel that can block on layer door hanging plate stops its shifted laterally.And rib also can stop that gear wheel moves up and departs from bank on anticreep.Multiple protective, thus trapping layer door strap entirety comes off, and ensure that the safety of elevator.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the front view of run-resistant elevator landing door in the embodiment of the present invention;
Fig. 2 is the side portion structure schematic diagram of run-resistant elevator landing door in the embodiment of the present invention;
Wherein: the upper bank of 1-, 2-line slide rail, 3-layer door hanging plate, 4-anticreep track, 4a-anticreep side block limit, 5-gear wheel, 6-anti-drop hook, rib on 7-anticreep, 8-straight-line groove.
Detailed description of the invention
Fig. 1 and Fig. 2 shows a specific embodiment of this run-resistant elevator landing door of the present invention, identical with traditional elevator layer door gear, it also comprises bank 1, be horizontally placed on line slide rail 2 on this on bank and be connected on described line slide rail by roller (not shown in FIG.) and can the layer door hanging plate 3 of parallel motion.During embody rule, rolling in roller left and right on line slide rail 2, thus drives layer door hanging plate 3 left and right horizontal to move, and then drive the elevator door On/Off be connected with layer door hanging plate.
The key improvements of the present embodiment is: described upper bank 1 also forms the anticreep track 4 that horizontal linear extends, on described layer door hanging plate 3, rotary connection has the gear wheel 5 be arranged in described anticreep track 4, the outside of described anticreep track 4 forms and upwards extends anticreep side block limit 4a, and this anticreep side block limit 4a keeps off the inner side left side of gear wheel (in the Fig. 2) at described gear wheel 5, thus gear wheel 5 is stoped to depart from anticreep track 4 left in fig. 2.
With reference to shown in Fig. 1, line slide rail 2 described in this example, anticreep track 4, anticreep side block limit 4a and upper bank 1 are structure as a whole.
In order to the slip-off preventing ability of enhancement layer door strap 3, this example is also provided with following structure: as shown in Figure 1, the top of described line slide rail 2, with the straight-line groove 8 of a linearly rail length directional spreding, described layer door hanging plate 3 is provided with and stretches in described straight-line groove 8 and can along the anti-drop hook 6 of this straight-line groove 8 horizontal slip.
Further, described upper bank 1 forms be positioned at above described gear wheel 5, with rib 7 on the anticreep stoping gear wheel 5 to move up.Gear wheel 5 to be arranged on described anticreep between rib 7 and anticreep track 4.As Fig. 2.
Will depart from from upper bank 1 once layer door hanging plate 3 because loosening or damage, the anti-drop hook 6 of layer door hanging plate 3 sidepiece just can be stuck in the straight-line groove 8 on line slide rail 2 top.Meanwhile, the gear wheel 5 that the anticreep side block limit 4a on upper bank 1 outside anticreep track 4 also can block on layer door hanging plate 3 stops its shifted laterally.And rib 7 also can stop that gear wheel 5 moves up and departs from bank on anticreep.Multiple protective, thus trapping layer door strap 3 entirety comes off, and ensure that the safety of elevator.
Generally, there are in an elevator landing door two layer door hanging plates 3, each layer door hanging plate 3 is preferably arranged the anti-drop hook 6 described in two, and these two anti-drop hook 6 horizontal interval (HI) distributions.
In the present embodiment, described anticreep track 4 is positioned at the below of described line slide rail 2, and described gear wheel 5 is positioned at the below of described anti-drop hook 6.
Certainly, above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to people can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalent transformations of doing according to the Spirit Essence of main technical schemes of the present invention or modification, all should be encompassed within protection scope of the present invention.
