Combined type polyurethane buffer for elevator has littleer cushion stroke, bigger cushion effect under specific condition, move safelyr to installation easy maintenance, long service life, advantages such as low in production cost.
Description
Technical field
The utility model relates to a kind of polyurethane bumper absorber, especially about the combined type polyurethane bumper absorber of a kind of low velocity little for the well pit degree of depth, heavy－duty elevator.
Background technology
Energy disperser is at the industry such as elevator, hoisting crane important role, and its high degree reduces the damage of equipment, and equipment can long-term safety be run.The polyurethane bumper absorber generally adopting light weight, withstanding corrosion, ageing-resistant, electrical isolation and explosion-proof performance good in existing elevator industry or machinery oil pressure type energy disperser.
But its height of conventional polyurethane bumper absorber is all greater than 1 with diameter ratio, and this just makes it compare and is applicable to the larger elevator of pit depth.If because pit depth is less, the height of so corresponding polyurethane bumper absorber is also wanted corresponding to reducing, and if its height reduction but the ratio of height diameter is constant, so its load-carrying capacity is just not enough to play buffer action to elevator again.Now may to cushion elevator with regard to needing multiple same polyurethane bumper absorber to combine.But like this, just not only to increase the quantity of polyurethane bumper absorber, also need to increase slow impingement plate at the bottom of sedan-chair or on underbeam to adapt to the quantity of energy disperser.Thus, just not only add productive costs, also add work capacity.
And although conventional machinery oil pressure type energy disperser also may be used for the less elevator of pit depth, the elevator that the configurations such as but it is mainly still applicable to Long Distances, linear velocity is high, pit depth is large are higher, so its price comparison is expensive, be more than the several times of polyurethane bumper absorber.
In addition, the utility model product can be directly installed on elevator hoistways pit cement flooring, does not need separately to join firm banking and connects.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Alleged herein " embodiment " or " embodiment " refers to special characteristic, structure or the characteristic that can be contained at least one implementation of the utility model.Different local in this manual " in one embodiment " occurred not all refers to same embodiment, neither be independent or optionally mutually exclusive with other embodiments embodiment.
Refer to Fig. 2, it is the cross-sectional view of elevator combined type polyurethane bumper absorber described in the utility model, in this embodiment, described elevator combined type polyurethane bumper absorber includes the first buffer body 100, bottom mounting plate 200 and the second buffer body 300, wherein the second buffer body 300 is arranged at the inside of the first buffer body 100, and its one end end portion is not fixedly connected with bottom mounting plate 200.
Consult Fig. 1 and Fig. 2, the first buffer body 100 is made up of polyurethane material, and cylindrical shape.It includes multiple loop buffer groove 110 and a compression release aperture 120.Loop buffer groove 110 is arranged at the first buffer body 100 outer ledge, and it is inner that compression release aperture 120 is arranged at the first buffer body 100, and compression release aperture 120 is communicated to bottom mounting plate 200.Loop buffer groove 110 and compression release aperture 120 prevent the first buffer body 100 be hit compression downwards time buffer body be outwards out of shape too much, cause it thoroughly to destroy, cannot recover.It is outwardly that loop buffer groove 110 reduces buffer body, and compression release aperture 120 makes buffer body to projecting inward, decreases the outwardly deformation of buffer body simultaneously.
In another embodiment, the height of the first buffer body 100 and diameter ratio are less than 3/4.Compared with existing polyurethane bumper absorber, the first buffer body 100 in the application decreases cushion stroke, increases cushion effect.A same height than the polyurethane bumper absorber being less than 3/4, can be comparable to multiple height and diameter than the ability to bear of the polyurethane bumper absorber being greater than 1 with diameter.
Consult Fig. 2 and Fig. 4, bottom mounting plate 200 includes an air extractor vent 210 and four fixed orifices 220.Bottom mounting plate 200 is rectangular, and position is provided with an air extractor vent 210 therebetween, and evenly distributed around air extractor vent 210 have four fixed orifices 220.Air extractor vent 210 is connected with compression release aperture 120, bottom mounting plate 200 by fixed orifice 220 directly and cement flooring be connected to a fixed.
Consult Fig. 2 and Fig. 3, the second buffer body 300 includes the first cotter seat 310, metal coil spring 320, second cotter seat 330 and dome plate 340.Wherein the first cotter seat 310 and the second cotter seat 330 are symmetricly set in outside the two ends of described metal coil spring 320.First cotter seat 310 is fixedly connected with bottom mounting plate 200 with the end, one end of metal coil spring 320, and the second cotter seat 330 is fixedly connected with dome plate 340 with the other end end of metal coil spring 320.First cotter seat 310, second cotter seat 330, metal coil spring 320, compression release aperture 120 and air extractor vent 210 are arranged in concentric, the aperture wherein compressing release aperture 120 is less than the internal diameter of metal coil spring 320, and the aperture of air extractor vent 210 is identical with the pore size of compression release aperture 120.And the position that metal coil spring 320 is connected with other parts polishes all, become plane-welding from original spot weld, add the intensity of connecting portion.It is inner that second buffer body 300 is placed in the first buffer body 100, when the first buffer body 100 is subject to impacting, pressure is delivered on dome plate 340, be delivered to further again on metal coil spring 320, its pressure is born completely from the first buffer body 100 and becomes the first buffer body 100 and the second buffer body 300 bears part of impact force separately, decrease the impulsive force suffered by the first buffer body 100, prevent the first buffer body 100 be subject to excessive impulsive force for a long time and be thoroughly out of shape, cannot recover.
The principle of work of elevator combined type polyurethane bumper absorber described in the utility model is: inserted by metal coil spring in polyurethane bumper absorber, reach the object of secondary buffer.Make at specified conditions and pit depth is little, elevator loading is large, energy disperser can have less cushion stroke and larger cushion effect.
The utility model has following beneficial effect:
1., under the limiting condition that, elevator loading little at pit depth is large, the utility model has less cushion stroke and larger cushion effect, runs safer.
2. the utility model can be directly fixed on cement flooring, and installation and maintenance are more convenient.
3. under given conditions, cushion effect of the present utility model is larger, and can adapt to the elevator of heavy－duty, avoid the problem needing multiple buffer in combination, productive costs is lower.
4. metal coil spring is wrapped up by the glue-line of polyurethane bumper absorber, corrodes, longer service life without steam, dust.
Above-mentioned explanation fully discloses detailed description of the invention of the present utility model.It is pointed out that the scope be familiar with person skilled in art and any change that detailed description of the invention of the present utility model is done all do not departed to claims of the present utility model.Correspondingly, the scope of claim of the present utility model is also not limited only to previous embodiment.
