Description
Technical field
The present invention relates to a kind of for example in the lift path of building via the elevator of rope car and counterweight, relate in particular to a kind of partition is passed to the vibration of rope hitch plate (hitch plate) from rope the structure of antivibration gear.
Background technology
Elevator possesses the driving that is used in the lift path of building suspension car and counterweight and uses rope.Use rope through being driven by actuating device, car and counterweight are moved on ascent direction and descent direction in lift path.
In recent years, in order efficiently to utilize the inner space of building, exploitation has the machine-roomless lift of the special-purpose machinery chamber that need not be used to be provided with actuating device.For example TOHKEMY 2005-29344 communique discloses an example of machine-roomless lift.Shown in figure 10, this kind machine-roomless lift has in the inside of lift path 1 and is used to pair of guide rails 2a, the 2b that guides car 5 to go up and down and is used to the pair of guide rails 4a, the 4b that guide counterweight 3 to go up and down. Guide rail 2a, 2b, 4a, 4b vertically hold up along lift path 1.Each guide rail 2a, 2b, 4a, 4b are supported on the wall of lift path 1 via a plurality of carriages (not shown).
Install pallet 8 on the top of guide rail 2a, 2b, 4a, 4b.Pallet 8 is made up of a plurality of support beams 7.Pallet 8 is placed on the supporting mechanism 10 on the top that is installed on each guide rail 2a, 2b, 4a, 4b by on even keel.
Pallet 8 is provided with actuating device 12.Actuating device 12 has traction sheave 13.Volume hangs with a plurality of drivings with rope 14 on traction sheave 13.Drive and moved back and forth to such an extent that be parallel to each other, and guided to the below of lift path 1 from traction sheave 13 with rope 14.An end that drives with rope 14 is connected on first rope hitch plate 17.The other end that drives with rope 14 is connected on second rope hitch plate 18.
Car 5 and counterweight 3 are suspended in the lift path 1 with rope 14 via driving.When traction sheave 13 rotations of actuating device 12, car 5 and counterweight 3 are moved at ascent direction or descent direction in lift path 1.
First rope hitch plate 17 is supported on the top of the guide rail 2a that car uses by on even keel via carriage 20.Second rope hitch plate 18 is supported on the top of pallet 8 by on even keel.
When making the elevator entry into service through startup actuating device 12, actuating device 12 vibrates.The vibration of actuating device 12 is passed on the wall of lift path 1 from pallet 8 through guide rail 2a, 2b, 4a, 4b, thereby becomes the reason that elevator produces noise.
For this is improved, in existing elevator, be supported between last guide 10 of each guide rail 2a, 2b, 4a, 4b and the pallet 8 and have antivibrating parts 24 respectively.Antivibrating parts 24 cuts off perhaps mitigation is passed to guide rail 2a, 2b, 4a, 4b from pallet 8 vibration.Thus, can suppress to produce noise.
On the other hand, TOHKEMY 2001-31346 communique discloses via bar (rod) and has connected the elevator that drives with rope being fixed with on the railway carriage or compartment frame of car.Bar runs through the rope hitch plate that is installed on the frame of railway carriage or compartment.Between the end of bar and rope hitch plate, set up coil spring.Coil spring is used to adjust the tractive force state that drives with rope.
The antivibrating parts that between a helical spring end and rope hitch plate, has rubber system.When car went up and down, antivibrating parts prevented coil spring and rope hitch plate mutual friction mutually.Thus, can be absorbed in the vibration of propagating between coil spring and the rope hitch plate through antivibrating parts.
According to disclosed elevator in TOHKEMY 2005-29344 communique, the vibration that actuating device 12 is produced also is passed to through traction sheave 13 and drives with rope 14.Therefore, in the elevator operation process, drive and vibrate with rope 14.
Usually, driving possesses hitch rod (shacklerod) with rope 14 respectively at the one of which end and the other end.Hitch rod runs through first and second rope hitch plate 17,18 at thickness direction.Coil spring is loaded onto in end at hitch rod.Coil spring is sandwiched between the end upper nut and first rope hitch plate 17 that is installed in a hitch rod, and is installed between the nut and second rope hitch plate on the end of another hitch rod.Thus, being applied to the load that drives on the rope is born by first and second rope hitch plate 17,18 via coil spring from hitch rod.
According to this structure, the vibration that drives with rope 14 is absorbed by above-mentioned coil spring to a certain extent.Therefore, be able to relax with the vibration that rope 14 is passed to first and second rope hitch plate 17,18 from driving.
But when coil spring was accepted to vibrate with rope 14 from driving, coil spring possibly cause vibration (surging) phenomenon.Therefore, in coil spring, can not cut off from driving and be passed to the vibration of first and second rope hitch plate 17,18, thereby can not expect sufficient vibrationproof performance with rope 14.
Especially, second rope hitch plate 18 be installed in the pallet 8 on the support beam 7 that antivibrating parts 24 is supported by guide rail 4b.Therefore, possibly cause from driving and be passed to the resonance effect that produces between the eigentone of vibration and support beam 7 of second rope hitch plate 18 with rope 14.Therefore, might encourage the vibration of second rope hitch plate 18, the vibrationproof performance is reduced.
According to disclosed structure in TOHKEMY 2001-31346 communique, the coil spring that adjustment drives with the tractive force of rope contacts with antivibrating parts.Therefore, the tension force that drives with rope acts directly on the antivibrating parts from coil spring.
Its result, for the performance that improves the antivibrating parts withstand load to suppress local distortion, need to improve the spring constant of antivibrating parts.And, can not negate the big situation of eigentone change that diminishes and prevent vibrating system because of the quality that is applied on the antivibrating parts.Therefore, the vibration that is passed to rope hitch plate from coil spring can not be cut off well, thereby sufficient vibrationproof performance can not be expected.
Summary of the invention
The objective of the invention is to obtain a kind of antivibration gear of elevator, the antivibration gear of said elevator can cut off reliably from rope and is passed to the vibration on the lift path, thereby can improve the vibrationproof performance.
In order to achieve the above object, the antivibration gear of the elevator of a mode of the present invention possesses: a plurality of ropes be used for suspension car and counterweight in lift path, and volume hang on the traction sheave of actuating device; Rope hitch plate is connected with the end of above-mentioned rope via coil spring; Load-carrying element is used in above-mentioned lift path, supporting above-mentioned rope hitch plate; And vibration absorber, be sandwiched between above-mentioned rope hitch plate and the above-mentioned load-carrying element, it is tabular to form rubber-like; Above-mentioned vibration absorber is arranged a plurality of cutting plates and is constituted through on the upper surface of above-mentioned load-carrying element, being separated with the compartment of terrain each other; Each above-mentioned cutting plate has the notch at its peripheral edge portion opening; The above-mentioned notch of adjacent above-mentioned cutting plate is faced each other on above-mentioned load-carrying element, and the end of above-mentioned rope is passed through between the above-mentioned notch of facing.
