Abstract
The utility model a support guide way for a door hanging plate assembly of a lift. One end of a guide way body is an arc top end which is matched with an upper pulley wheel in the door plate connecting hanging plate, and the other end part of a relative position of the guide way body is an arc top end which is provided with the same structural form with the arc top end.
Description
The utility model relates to for used support rails of elevator door link plate assembly such as the door opener of elevator door and layer door gears.
In door strap assemblies such as the door opener of elevator door and layer door, support rails is to make door-plate make one of indispensable composition structure that the open and close door moves.The present structure that this guide rail adopted is only in the top for having the form of cambered top end that the top sheave that can be connected with door-plate in the link plate assembly is made the R arc surface of running-fit, and the lower end relative with it generally then is planar structure.Only there is the mono-arc surface to contact because door-plate connects between pulley and guide rail in the link plate assembly, is connected with this link plate behind the door-plate, caused the line of centers of its line of centers and guide rail not parallel, influenced the running quality of elevator door because of centre-of gravity shift.In addition, be main between this cambered top end because of the link plate that is connected with door-plate and guide rail, or even unique long-term stressed friction position and fragile position, must be more to renew guide rail again in case damage, also be a factor that influences use cost.
The purpose of this utility model is at above-mentioned situation, a kind of line of centers keeping parallelism that makes door-plate connect link plate and guide rail is provided, improve the running quality of elevator, and can reduce the replacing frequency of new guide rail, and then can reduce the used support rails of elevator door link plate assembly of use cost.
The used support rails of elevator door link plate assembly of the present utility model, do on the basis of cambered top end of running-fit for being connected top sheave in the link plate assembly at an end of existing guide rail with door-plate, make with the other end of the guide rail at its relative position place also for having the cambered top end of same structure form with said this cambered top end.When installing and using, can directly on said guide rail, carry out, but said guide rail is provided with the assembling structure of the concave or convex form of being convenient to install, obviously can has the convenient flexible and adaptive advantage of expansion.Because the opposite end in the support rails of the present utility model is the top with arc structure, therefore on the one hand, be provided with members such as two pulleys up and down that can be that the mounting board shape cooperates or roller in corresponding position on the door-plate link plate after, by its self-centering action, can make the line of centers of this link plate and support rails can remain parastate, make the running quality of elevator have stable and the failure-free assurance; On the other hand, after the upper end of the main stressed abrading section of support rails arc surface is worn, after the two ends up and down of guide rail are changed mutually, can make prolong one times the service life of this support rails not influencing its Self-centering Action and reliable and stable the reaching of elevator running quality more not renewed under the prerequisite of guide rail.
Below with example shown in the drawings foregoing of the present utility model is described further.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 a kind of version of the utility model support rails.
Fig. 2 is the another kind of version of the utility model support rails.
Fig. 3 is another version of the utility model support rails.
Fig. 4 is another version of the utility model support rails.
A kind of basic structure form that shown in Figure 1 is in the used support rails of the utility model elevator door link plate assembly.Its guide rail 3 relative two ends up and down are cambered top end 1 and the cambered top end 2 that the top sheave that can be connected with door-plate in the link plate assembly is made the same structure form of running-fit, and its guide rail 3 can directly use as mounting structure.
Shown in Figure 2 is on the basis of the support rails structure of Fig. 1, is provided with the inner concave shape assembling structure of installing when easy to use 4 on its guide rail 3 specially.
Fig. 3 and shown in Figure 4 be that said guide rail 3 is provided with the multi-form male type assembling structure of installing when easy to use 4.
Claims (4)
1. the used support rails of elevator door link plate assembly, one end of guide rail (3) is made the cambered top end (1) of running-fit for being connected top sheave in the link plate assembly with door-plate, it is characterized in that with the other end (2) at cambered top end (1) the relative position place of said guide rail (3) for having the cambered top end with said cambered top end (1) same structure form.
2. support rails as claimed in claim 1 is characterized in that having the structure (4) that is used to install on the said guide rail (3).
3. support rails as claimed in claim 2 is characterized in that the structure (4) that is used to install on the said guide rail (3) is the inner concave shape structure.
4. support rails as claimed in claim 2 is characterized in that the structure (4) that is used to install on the said guide rail (3) is the male type structure.
