Abstract
The utility model relates to an inlayed guide rail for an elevator door opening machine comprising a guide rail seat. A groove is arranged on the top of guide rail seat, and a cylindrical optical shaft is arranged in the groove. Surface smoothness of the optical shaft is 5-14 mu, the groove is in a semi-circular shape, and a positioning groove is arranged on the positive face of the guide rail seat. The inlayed guide rail has the advantages of being light in weight, and high in surface smoothness, reducing friction coefficient of an upper pulley of an elevator, prolonging service life of the upper pulley, high in straightness of the guide rail in the length direction, low in noise and high in safety coefficient, and the upper pulley can not produce fluctuations in operation.
Description
Technical field
The utility model relates to a kind of cage guide, especially relates to a kind of door opening machine for elevator and uses inserted guide rail.
Background technology
At present, elevator kind on the market generally is divided into two kinds, hand-held type elevator and high low type elevator.The high low type elevator structure is relatively complicated; Particularly the high low type elevator is provided with the elevator door that is used for protecting passenger safety; The switching of elevator door for ease, elevator door need be realized out and closes through door opener, and important position is rail sections in the door opener.Existing door opening machine for elevator guide material is Q235, and quality is heavier, and the guide rail surface degree of finish is lower, and friction coefficient is than higher, thereby can reduce the service life of elevator top sheave; The length direction straightness accuracy of guide rail is low simultaneously, and the elevator top sheave can produce fluctuation in operation, and the operation noise is bigger, and safety and noise aspect are produced certain influence.
Summary of the invention
The utility model technical matters to be solved provides that a kind of weight is light, straightness accuracy and the high door opening machine for elevator of surface finish are used inserted guide rail.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme: a kind of door opening machine for elevator is used inserted guide rail, has track base, and said track base top is provided with groove, is provided with cylindrical optical axis in the groove.
In order to reduce the guide rail surface friction coefficient, guarantee the service life of elevator top sheave, further, the surface finish of said optical axis is 5-14 μ.
Guide rail is installed for ease, more further, and said groove semicircular in shape.
For the ease of circular hole being set on track base and having aesthetic, further, said track base front is provided with positioning groove.
Compared with prior art, the usefulness of the utility model is: this door opening machine for elevator is light with inserted quality of guide rail, and surface finish is high; Reduced the friction coefficient of elevator top sheave; Thereby improve the service life of top sheave, and rail length direction straightness accuracy is high, top sheave can not produce fluctuation when operation; Noise is low, and safety factor is high.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is that the utility model door opening machine for elevator is with inserted guide rail positive dirction structural representation;
Fig. 2 is that the utility model door opening machine for elevator is with inserted guide rail reversing sense structural representation;
Fig. 3 is that the utility model door opening machine for elevator is with inserted rail mounting structure scheme drawing.
Among the figure: 1, track base; 2, optical axis; 3, groove; 4, positioning groove.
The specific embodiment:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in detail:
Fig. 1, Fig. 2 and a kind of door opening machine for elevator shown in Figure 3 are used inserted guide rail, have track base 1, and said track base 1 top is provided with groove 3, is provided with cylindrical optical axis 2 in the groove 3; Optical axis 2 is embedded in the groove 3 for ease, said groove 3 semicirculars in shape; The surface finish of said optical axis 2 is 5-14 μ, has improved the surface finish of guide rail, the friction coefficient of guide rail is reduced, thereby reduced the friction between elevator top sheave and the guide rail, has improved the service life of elevator top sheave; And the length direction straightness accuracy of optical axis 2 is improved, thereby guarantees that the elevator upper rail can not produce fluctuation in operation, improved elevator safety property and reduced noise; The hole is set on track base 1 for ease and makes track base 1 have aesthetic property, said track base 1 front is provided with positioning groove 4.
This door opening machine for elevator is light with inserted quality of guide rail, and surface finish is high, has reduced the friction coefficient of elevator top sheave; Thereby improve the service life of top sheave, and rail length direction straightness accuracy is high, top sheave can not produce fluctuation when operation; Noise is low, and safety factor is high.
It is emphasized that: above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
