Definition from guide rail, guide rail is the important reference component of vertical lift, automatic elevator, step of moving pavement, it is controlling lift car, escalator and step of moving pavement running orbit, ensure the transmission of operation signal, it relates to again the vitals of elevator safety and running quality.
The effect of guide rail mainly comprises: 1) guide rail play the guiding role to the dipping and heaving of elevator.2) freedom of movement of restriction car and counterweight.3) prevent the inclination that the unbalance loading due to car produces, bear the power of laying particular stress on.4), when safety tongs moves, guide rail, as the supporting member being held, supports car or counterweight.Power withstands shocks.
The classification of guide rail, divides three kinds of T-shaped, L-type and hollow types from cross sectional shape.1, T shape guide rail, is to make guide rail with the most use in current China elevator, its highly versatile, and there is good anti-bending strength and processibility.2, L-type guide rail, rigidity and surface accuracy are lower, and rough surface, therefore can only be for dumb waiter and all kinds of not man lifts' counter weight guide track.3, hollow guide rail, forms with sheet steel rolling, and precision is high compared with L-type, has certain rigidity, is used for counterweight without low, the express lift counter weight guide track of safety tongs.
For elevator, operation plays an important role guide rail.For a long time operation can make the surface of guide rail produce wearing and tearing, and the dust in elevator hoistways is more, and dust accumulation can make to lead boots while moving on guide rail on guide rail, increases the weight of the wearing and tearing of guide rail.The general terms of settlement adopting is on guide rail, to add lubricating oil, but guide rail in hoistway, can make to add lubricating oil very inconvenient in elevator.
Summary of the invention
Object of the present invention solves the problem that traditional cage guide adds lubricating oil inconvenience.Mainly by adopting the cage guide with microcellular structure to solve.Concrete technical scheme is:
With a cage guide for gradient microporous structure, guide rail inside is cavity, and the outer wall of guide rail is the rigid material with microcellular structure, and the aperture of micropore diminishes from top to bottom gradually, is provided with the lubricating oil jetting system being communicated with cavity on the top of guide rail.
Because traditional cage guide is by applying lubricating oil on outside direction guiding rail, this method inconvenience very.In technical scheme of the present invention, on the outer wall of guide rail, include microcellular structure, because inside is cavity, add lubricating oil in cavity after, by certain pressure, can make lubricating oil ooze out by the micropore on guide rail, reach the effect of lubricated guide rail.Further, because lubricating oil has certain gravity, the lubricating oil on guide rail top can trickle to bottom along with the effect of gravity, therefore, can the microcellular structure on top be arranged largerly, the lubricating oil flowing out from top, along guide rail trickling downwards, makes the lubricating oil of upper and lower two positions more even.
Described rigid material in the present invention can be corrosion-resistant steel, pottery etc.Can prepare by the technology more having the corrosion-resistant steel with the big or small micropore of difference, ceramic tubing.
The cross sectional shape of the cage guide described in the present invention can be circle, T shape etc.
Further preferably, the pore diameter range of described micropore is 100 μ m～1 mm.
As improvement of the present invention, in the bottom of cage guide, be also provided with the air jet system being communicated with cavity.This is owing to having more dust in hoistway, and these dirt accumulation can exert an influence to the flatness of guide rail on guide rail, can accelerate the wearing and tearing of guide rail.Therefore, regularly by air jet system, from cavity, eject air, can blow away the dust being gathered on guide rail, extend the life-span of guide rail.
As improvement of the present invention, in the cavity of cage guide, be also provided with inner tube.Inner tube can reduce the volume of cavity, reduces lubricating oil accumulating in cavity, thereby has guaranteed the effect that lubricating oil or air eject, and also can keep guide rail to have enough face areies, and then can contact with leading boots better simultaneously, guarantees elevator operation.
beneficial effect
Cage guide with micropore provided by the invention, direction guiding rail surface applies lubricating oil effectively, has solved the problem of orthodox method inconvenience, has extended the life-span of guide rail, makes elevator operation more steady.
