Abstract
The utility model discloses an air pressure buffer of elevator, this air pressure buffer of elevator include cylindric cylinder body, connect cylinder cap, the piston of setting in the cylinder body on the cylinder body, be connected with the piston rod on the piston, pack the air in the cylinder body, a plurality of orifices have been seted up to cylinder body face of cylinder bottom, be equipped with the guide post in the cylinder body, be equipped with the spring on the guide post, install one -way admission valve on the piston, the inlet port has been seted up on the cylinder cap, the utility model discloses a with the atmospheric pressure buffer of elevator buffer design for filling the air, so both energy -concerving and environment -protective, reduction reset time and heat dissipation that again can be great be fast, have very big progressive meaning and practical value.
Description
Technical field
The utility model relates to a kind of elevator system components, particularly relates to a kind of buffer of elevator.
Background technique
Buffer is a vitals in elevator safety protection system, what current buffer of elevator great majority adopted is hydraulic bjuffer, it utilizes the damping function of flow of fluid in cylinder body to cushion the impact of car or counterweight, but common hydraulic bjuffer has not been hermetic, in the process of piston movement, have a small amount of gasification hydraulic oil to overflow, thus pollute environment, simultaneously along with the prolongation of hydraulic bjuffer service time, also must to annex solution force feed in its cylinder, which adds financial cost, waste the energy; And hydraulic oil is is not easily scattered and disappeared can be produced a large amount of heat in the process compressed, this life of hydraulic oil belongs to inflammable liquid, so just there is very large potential safety hazard, and hydraulic oil is from being compressed to, and to return to original state needed time longer, there is the possibility that elevator secondary falls in the process, this also also exists great potential safety hazard.
Model utility content
Technical problem to be solved in the utility model is to provide the air pressure buffer of elevator of a kind of energy-saving and environmental protection, resetting time short, rapid heat dissipation.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of air pressure buffer of elevator, comprise cylindric cylinder body, the cylinder cap be connected on cylinder body, the piston be arranged in cylinder body, described piston is connected with piston rod, air is filled in described cylinder body, bottom, described cylinder body cylndrical surface offers some throttle orifices, and be provided with directional post in described cylinder body, described directional post is provided with spring, described piston is provided with breather cheek valve, described cylinder cap offers inlet hole.By filling air, achieve energy-saving and environmental protection; Offer some throttle orifices in bottom, cylinder body cylndrical surface, be convenient to so effectively dispel the heat in the process of piston compression; By being provided with directional post in cylinder body, piston can be made to move more stably, on directional post, being provided with spring simultaneously, can piston being made fast to return to initial position like this, resistance can be provided for piston compression again; By installing breather cheek valve on piston, pneumatic buffer Rapid inhalation can be made like this to return to original state, can ensure that again in the process of piston compression, gas can not spill from piston simultaneously.
As preferably, the aperture of described throttle orifice is inner small and outside big, is convenient to pneumatic buffer like this and effectively dispels the heat in the process of piston compression.
As preferably, described some throttle orifices are uniform ringwise, be convenient to like this pneumatic buffer can in the process of piston compression Homogeneouslly-radiating.
As preferably, described piston rod top is provided with cushion pad, is convenient to the sub-fraction kinetic energy that can consume car or counterweight in the process of clashing at car and piston rod like this.
As preferably, the fitting surface of described piston and directional post is provided with seal ring, can ensure that the fitting surface of piston and directional post realizes sealing like this.
As preferably, the quantity of described directional post is 2 to 4, and being convenient to piston like this can uniform force and moving more stably.
Compared with prior art, the beneficial effect of a kind of air pressure buffer of elevator of the utility model: by buffer of elevator being designed to the pneumatic buffer of filling air, so both energy-conserving and environment-protective, can reduce resetting time and rapid heat dissipation again greatly, and tool has greatly improved meaning and use value.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of air pressure buffer of elevator of the utility model.
Wherein, reference character: 1 is cylinder body, 2 is cylinder cap, and 3 is piston, and 4 is piston rod, and 5 is air, and 6 is throttle orifice, and 7 is directional post, and 8 is spring, and 9 is individual event suction valve, and 10 is inlet hole, and 11 is cushion pad, and 12 is seal ring.
Embodiment
All features disclosed in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Arbitrary feature disclosed in this specification, unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
As shown in Figure 1, a kind of air pressure buffer of elevator of the utility model, comprise cylindric cylinder body 1, the cylinder cap 2 be connected on cylinder body 1, the piston 3 be arranged in cylinder body 1, described piston 3 is connected with piston rod 4, and fill air 5 in described cylinder body 1, bottom, described cylinder body 1 cylndrical surface offers some throttle orifices 6, directional post 7 is provided with in described cylinder body 1, described directional post 7 is provided with spring 8, and described piston 3 is provided with breather cheek valve 9, and described cylinder cap 2 offers inlet hole 10.
As shown in Figure 1, in a kind of air pressure buffer of elevator of the utility model, described throttle orifice 6 aperture is inner small and outside big, directional post 7 is provided with in described cylinder body 1, directional post 7 quantity is 2 to 4, here be set to 3, described piston rod 4 top is provided with cushion pad 11, and the fitting surface of described piston and directional post is provided with seal ring 12.
As shown in Figure 1, in a kind of air pressure buffer of elevator of the utility model, when piston is under pressure, piston moves downward, the air in compression cylinder, and air is discharged by throttle orifice simultaneously, is convenient to the heat that emission gases produces because of compression; After pressure is cancelled, air passes into cylinder rapidly by breather cheek valve, and piston resets rapidly, and whole pneumatic buffer is returned to original state.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; every do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
