For solving the problems of the technologies described above, the utility model provides a kind of buffer of elevator, comprise base and the hydraulic ram of being located on the base, also comprise and be nested in first order plunger, second stage plunger and third stage plunger in the described hydraulic ram from top to bottom successively, and between the adjacent plunger, be equipped with compression reseting spring between third stage plunger and the described hydraulic ram, described hydraulic ram inner bottom part was provided with beam hanger, and the bottom of plungers at different levels is equipped with and supplies the described oil-through hole that beam hanger passes of crossing; Be equipped with vertical hollow oil transportation bar in second stage plunger and the third stage plunger, hollow oil transportation bar be positioned at its oil-through hole with the one-level plunger and be connected, and the hollow oil transportation bar of second stage plunger can be placed in the outside of the hollow oil transportation bar of third stage plunger, the hollow oil transportation bar of third stage plunger can be placed in the outside of crossing beam hanger in the described hydraulic ram, and the sidewall of described hollow oil transportation bar is provided with a plurality of oil throughs.
In a preferred embodiment, the top side wall of described second stage plunger is provided with oil hole, and this oil hole is provided with plug cock, and plug cock is provided with oil scale.
In a preferred embodiment, be provided with seal ring between the adjacent plunger.
In a preferred embodiment, the lateral wall top of described hydraulic ram be provided with for the control elevator safety loop cut off can automatically reset lead limit switch, the lateral wall top of described first order plunger is provided with the switch actuating plate, when buffer of elevator was compressed into the setting stroke, described lead limit switch action was touched in the bottom of described switch actuating plate.
The beneficial effects of the utility model are: because after adopting three grades of nested type piston structures and crossing the beam hanger structure, under the prerequisite of the compression stroke that guarantees to reach same requirement, the compression stroke that can the compression stroke that energy disperser is overall be decomposed into plungers at different levels, reduced the whole height of energy disperser after oil cylinder and the compression, thereby reduce the elevator hoistways degree of depth, reduce the hoistway building cost.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Embodiment:
To shown in Figure 3, a kind of buffer of elevator comprises base 1 and the hydraulic ram of being located on the base 12 as Fig. 1, also comprises being nested in first order plungers 3, second stage plunger 4 and third stage plunger 5 in the described hydraulic ram 2 from top to bottom successively.Between the adjacent plunger, be equipped with compression reseting spring 6 between third stage plunger 5 and the described hydraulic ram 2, be used for making the elongation state before each plunger after the compression returns to compression, described compression reseting spring 6 is installed on the inside of plunger and the inside of hydraulic ram 2.Described hydraulic ram 2 inner bottom parts were provided with beam hanger 7, and crossing beam hanger 7 can be for hollow, also can be for solid.The bottom of first order plunger 3, second stage plunger 4 and third stage plunger 5 is equipped with and supplies the described oil-through hole (not indicating among the figure) that beam hanger 7 passes of crossing.Be equipped with vertical hollow oil transportation bar 8 in second stage plunger 4 and the third stage plunger 5, hollow oil transportation bar 8 be positioned at its oil-through hole with the one-level plunger and be connected, and the hollow oil transportation bar 8 of second stage plunger 4 can be placed in the outside of the hollow oil transportation bar 8 of third stage plunger 5, and the hollow oil transportation bar 8 of third stage plunger 5 can be placed in the outside of crossing beam hanger 7 in the described hydraulic ram 2.The sidewall of described hollow oil transportation bar 8 is provided with a plurality of oil throughs 9, and the quantity of oil through 9 can be according to the needs of production setting.
In the present embodiment, the top side wall of described second stage plunger 4 is provided with oil hole 10, and this oil hole 10 is provided with plug cock 11, and plug cock 11 is provided with oil scale (not indicating among the figure).Be provided with seal ring (not indicating among the figure) between the adjacent plunger, can stop fully to slide mutually between the adjacent two-stage plunger possibility of leakage of oil occurs.The lateral wall top of described hydraulic ram 2 be provided with for the control elevator safety loop cut off can automatically reset lead limit switch 12, the lateral wall top of described first order plunger 3 is provided with switch actuating plate 13, when buffer of elevator was compressed into the setting stroke, described lead limit switch 12 actions were touched in the bottom of described switch actuating plate 13.Make the contact of lead limit switch 12 compressed and keep compressive state to reset under compression reseting spring 6 effects up to buffer of elevator, switch actuating plate 13 leaves till the lead limit switch 12 always, and the contact of lead limit switch 12 automatically resets.
The described buffer of elevator of present embodiment, its working process is as follows:
When buffer of elevator was in normal condition, fluid was filled in second stage plunger 4 and third stage plunger 5 and hydraulic ram 2 inner chambers, and buffer of elevator keeps maximum height under the effect of compression reseting spring 6.When lift car or counterweight cushion at collision, first order plunger 3 moves downward, and the fluid in the second stage plunger 4 can be excessive in the inner chamber of first order plunger 3 by the oil-through hole of first order plunger 3 bottoms by 3 compressings of first order plunger.In like manner, the fluid in the third stage plunger 5 can be excessive in the inner chamber of second stage plunger 4 by the oil through 9 that arranges on the hollow oil transportation bar 8 of second stage plunger 4 by 4 compressings of second stage plunger; Fluid in the hydraulic ram 2 can be excessive in the inner chamber of third stage plunger 5 by the oil through 9 that arranges on the hollow oil transportation bar 8 of third stage plunger 5 by 5 compressings of third stage plunger; First order plunger 3, second stage plunger 4, third stage plunger 5 and hydraulic ram 2, hollow oil transportation bar 8 and mistake beam hanger 7 can overlap together step by step, and the retracing spring in hydraulic ram 2 and the inner chamber also is confined state.Because first order plunger 3 moves downward, drive switch actuating plate 13 and move downward, can touch the lead limit switch 12 that is arranged on the hydraulic ram 2, elevator safety loop is cut off, the main frame outage only stops car.After lift car or counterweight leave energy disperser, the retracing spring of compressive state makes plunger returns at different levels, fluid is refluxed in following plungers at different levels and hydraulic ram 2 by first order plunger 3 inner chambers, switch actuating plate 13 breaks away from lead limit switch 12 contacts with first order plunger 3 upward movements simultaneously, lead limit switch 12 automatically resets, connect safety return circuit, the main frame energising, elevator recovers the use state.
The above embodiment has only expressed the specific embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
