Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments。Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the premise not making creative work, broadly fall into the scope of protection of the invention。
Refer to the structural representation that Fig. 1 to Fig. 3, Fig. 1 are elevator steel band cover of wedge suspension apparatus of the present invention；Fig. 2 is the cross-sectional schematic of Fig. 1；Fig. 3 is the partial sectional schematic view of steel band in Fig. 2。As shown in Figure 1 to Figure 3, described suspension arrangement includes steel band 7, voussoir 4, cover of wedge 5, screw rod 1, wedge yoke 3, split pin 2 and nylon cable tie 6。
Please continue to refer to Fig. 3。One surface of described steel band 7 has multiple groove 71。Multiple grooves 71 are along the parallel longitudinal arrangement of steel band 7。The plurality of groove 71 is arranged at equal intervals。In a preferred embodiment, the groove height A of described groove 71 is 2.5mm, and the angle [alpha] formed between adjacent groove 71 is 72.5 °。Described steel band 7 has reeded surface and contacts with voussoir 4, and when steel band 7 is subject to pulling force vertically downward, the shape of this groove 71 enables to the coefficient of friction between steel band 7 and voussoir 4 and increases, steel band 7 not easily landing。
Described voussoir 4 is contained in described cover of wedge 5 and matches with described cover of wedge 5, and described cover of wedge 5 has vertical inner surface 51 and inclined inner surface 52。Described inclined inner surface 52 has multiple projection (not shown), it is formed with steel band passage (not shown) between described voussoir 4 and vertical inner surface 51, steel band passage (not shown) it is formed with between described voussoir 4 and inclined inner surface 52, one end of described steel band 7 is through steel band passage and stretches out cover of wedge 5, and the steel band one end stretching out cover of wedge 5 is bundled by nylon cable tie 6 thus collapsing in one end of described cover of wedge 5 with the other end。
Multiple projections are formed on inclined inner surface 52 by molten steel casting, good fluidity during molten steel casting, it is easier to fill the female in mould, both ensure that roughness, in turn ensure that casting cycle can better molding。Multiple projections are connected with each other, and mainly avoid due to the misrun of conventional point-like texture in casting cycle, and the height of described projection is 0.5mm, thus ensure that qualified cast rate。Projection in the present invention can be regular or irregularly shaped。Described inclined inner surface 52 contacts with another surface of described steel band 7。When steel band 7 is subject to pulling force vertically downward, the shape of this projection enables to the coefficient of friction between the inclined inner surface 52 of steel band 7 and cover of wedge 5 and increases, and more ensure that steel band 7 not easily landing。
Described wedge yoke 3 is positioned at the other end of described cover of wedge 5, the end clips of described screw rod 1 is held in wedge yoke 3, described screw rod 1 offers the through hole (not shown) passed through for split pin 2, by described split pin 2 through through hole, thus being fixed in described cover of wedge 5 by screw rod 1。
Elevator is in the process of work, when steel band 7 is subject to pulling force vertically downward, on steel band 7, pulling force vertically downward balances mutually with the component of the stiction vertical direction acted on inclined inner surface 52, another component positive acting of stiction is on the inclined-plane inner surface 52 of cover of wedge 5, thus forming the retaining mechanism of a self-locking type, steel band 7 is below more toward drop-down, and stiction is more big to the pressure on inclined-plane, and frictional force is also more big。
The elevator steel band cover of wedge suspension apparatus of the present invention, has the advantage that
(1) adopt teeth groove steel band of model surface, increase the coefficient of friction between steel band and voussoir, promote safety coefficient。
(2) the internal surface adopted with texture of cover of wedge, increases the coefficient of friction of cover of wedge and the main stress surface of steel band contact portion, promotes safety coefficient。
(3) cover of wedge inclined inner surface adopts the texture that bossing is connected, good fluidity during molten steel casting, it is easier to fills the female in mould, both ensure that roughness, in turn ensure that casting cycle can better molding。
The above disclosed several preferred embodiments being only the present invention, certainly can not limit the interest field of the present invention, the equivalent variations therefore made according to the claims in the present invention with this, still belong to the scope that the present invention contains。
