Abstract
The utility model relates to a lift door movement device. Guide support structures are arranged on a base plate structure matched with door plate connecting hanging plates which move along the base plate structure, wherein the guide support structures are two stages which oppositely extend in the same rectilinear direction, via scrolling mechanisms, the guide support structures are respectively matched with the door plate connecting hanging plates which do reciprocating movement on the guide support structures and are connected with each other via a synchronous drive structure, and limiting structures for controlling a movement end point of the door plate connecting hanging plates which are arranged on the guide support structures are arranged on at least one side end part of the two mutual adjacent opposite ends of the two guide support structures. Each of the door plate connecting hanging plates is respectively connected with check clip wheels which can maintain contact with the guide support structures via elastic structure components.
Description
The utility model relates to door opener and motion of mechanism device such as layer door gear etc. in the elevator.
In the car of elevator, be provided with door opener, in each floor of building that elevator is installed, also be respectively arranged with corresponding landing door structure.Make it make the running gear of switch door motion, all be the guided bearing structures such as guide rail that multi-form monolithic devices is set on the board structure that is used for fixing generally at present, and be provided with in the running-fit mode that drive mechanism through the form of being synchronized with the movement is connected thereon and can be reciprocating, and be connected link plate with door-plate that the terminal point position limiting structure of appropriate form matches.For preventing that this door-plate from connecting the link plate on the go unforeseen circumstancess such as derailing take place, each connect between link plate and this guided bearing structure match divided by rolling mechanisms such as normal pulleys outside, also be provided with and do the block card cooperation with it from last inferior different directions, maintain the safety control structures such as safety wheel in necessary gap again with this guided bearing structure.Because the gate-width of each installation place, place to use is also incomplete same, therefore the substrate and the guided bearing structure of this overall structure form just can only be distinguished independent production and processing in the employed running gear of each elevator door, brought many inconvenience and difficult in actual use.On the other hand, connect between safety wheel and guided bearing structure on the link plate and must keep suitable tolerance clearance, also make in the operational process of elevator and easy generation noise in the process of switch door, influence traveling comfort owing to be fixedly installed in door-plate.
At above-mentioned situation, the purpose of this utility model provides a kind of simple in structure, and is easy for installation, can have commonality and comformability widely, and can further improve the elevator door running gear of operation stability.
The structure of the utility model elevator door running gear is that board structure is provided with the guided bearing structure of guide rail or other appropriate configuration form, and is provided with door-plate connection link plate thereon.Guided bearing structure wherein be on same rectilinear direction by two sections of the opposing extension in center, being combined with through rolling mechanism respectively on it can be reciprocating thereon and connect link plate through the interconnective door-plate of the synchrodrive structure that its maintenance is synchronized with the movement.At least one side end in two close mutually opposite ends of two guided bearing structures is provided with to be used to control and is matched with the position limiting structure that the structural door-plate of this guided bearing connects the link plate exercise end, also is connected with respectively and can remains the block card wheel that contacts with said guided bearing structure through elastic structure on each door-plate connection link plate.Because what the guided bearing structure in the device adopted is along two section the version of same straight line by the opposing extension in center, just can be under the prerequisite that does not change board structure, can be easily by on the rectilinear direction at its place, suitably regulating the purpose that its two intersegmental spacing reaches the overall width of adjusting whole guided bearing structure, thereby it both can be had to realize regularization production, can have the two-fold advantage of commonality and applicability widely again.Simultaneously, the guided bearing structure of monolithic devices is become two sections that length shortens relatively, also can reduce this guided bearing framing member greatly, made things convenient for processing adding the difficulty of man-hour in the straightness accuracy requirement.On the other hand, connect at each door-plate and all to connect on link plate and can take turns with the block card that said guided bearing structure can remain " the dynamically floating " form that contacts and eliminate tolerance clearance therebetween, thereby also make the elevator can be more steady in operational process with elastic structure.
Below foregoing of the present utility model is described further with example shown in the drawings.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.
Fig. 1 is the constructional drawing of present widely used elevator door running gear.
Fig. 2 is the constructional drawing of the utility model elevator door running gear.
Fig. 3 is the A-A constructional drawing of Fig. 2.
Shown in Figure 1 is now the structure of widely used elevator door running gear.Its board structure 1 and on it institute's bonded assembly guide rail 2 all are framing members of monolithic devices.The synchronous drive mechanism 9 that this guide rail 2 is provided with through its maintenance is synchronized with the movement interconnects, and be connected link plate 3 with door-plate that terminal point position limiting structure 4 matches, itself and guide rail 2 are made running-fit through top sheave 5, make it can be reciprocating on guide rail 2 neatly.
Fig. 2 and elevator door running gear of the present utility model shown in Figure 3.On the substrate 1 with on same rectilinear direction by the opposing extension in center, and can be provided with two sections linear support rails 2 in the mode of the rectilinear direction adjusted spacing at its place.Being combined with through top sheave 5 respectively on it can be reciprocating thereon, and the door-plate of doing to be in transmission connection through the drive mechanism 9 that its maintenance is synchronized with the movement connects link plate 3.Be provided with the position-limited wheel 4 that is used to control door-plate connection link plate 3 exercise ends near the side end place in the two-phase end mutually at two support rails 2.Each door-plate connects on link plate 3 respectively through extension spring framing member 6 and is connected with and can takes turns 8 with the lower edge beginning of this support rails 2 " dynamically floating " the formula block card that cooperates of keeping in touch eventually.On said door-plate connection link plate 3, also be provided with the safety wheel 7 that can match with the upper limb of said support rails 2.
