Description
Technical field
The present invention relates to the buffering stopper of elevator, the signal being specifically related to a kind of hydraulic buffer of elevator triggers dress
Put.
Background technology
The oil buffer of elevator is arranged at the bottom of elevator, and it utilizes damping force that liquid flows to slow down sedan-chair
Impact time falling in railway carriage or compartment, and utilize spring to make it reset.Described oil buffer is mainly triggered dress by cylinder body, plunger and signal
Putting composition, wherein, described cylinder body constitutes the main body of buffer together with plunger combination, and described signal triggers device and is used for detecting
The downward storke of plunger, when plunger runs down to certain position with car, described signal triggers device and sends triggering signal,
And deliver to control system.Described signal triggers device and is made up of travel switch and touching lever, and wherein, described travel switch is arranged at cylinder
On body, the upper end of plunger is fixed in the upper end of described touching lever, and the lower end of touching lever extends downward the top of travel switch, touching lever
Lower end is provided with the touch surface of inclination；During work, touching lever moves downward with plunger, opens when the touch surface on touching lever contacts described stroke
Guan Shi, travel switch obtains and triggers signal.
Existing signal triggers device and has the disadvantage that
1, it is that lower end cantilever design freely is fixed in upper end due to touching lever, and touching lever is the most relatively long, when on touching lever
When touch surface contacts with travel switch, travel switch the active force that touch surface produces is promoted the lower end edge horizontal direction of touching lever to
Outer motion, its defect brought is, on the one hand, make Time delay, and the triggering stroke that touching lever runs downwards in other words increases,
Thus car can not be controlled in time and stop, safety is affected；On the other hand, produce during touching lever contacting travel switch and rock,
Thus affect the stability triggering signal.
2, touching lever is in use deformed continually by the extruding of travel switch, and the later stage top that works long hours holds
Easily there is fracture or produce expendable lateral deformation, also resulting in Time delay simultaneously and even lost efficacy, the use of touching lever
Life-span is short, and there is potential safety hazard.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that the signal of a kind of elevator oil buffer touches
Transmitting apparatus, when this signal triggers device work, touching lever will not produce and rock, and has the advantages such as safe and stable property, good reliability.
The purpose of the present invention is realized by following technical scheme:
The signal of a kind of elevator oil buffer triggers device, including travel switch and touching lever, wherein, described stroke
Switch is arranged on the cylinder body of oil buffer, and the upper end of the plunger of oil buffer, touching lever are fixed in the upper end of described touching lever
Lower end extend downward the top of travel switch；The lower end of described touching lever be provided with towards away from travel switch direction bend curved
Folding part, in this kink, the side towards travel switch constitutes touch surface；Described cylinder body is provided with limit base, and this limit base is positioned at
The top of the kink of touching lever and close to this kink, this limit base is provided with the stopper slot matched with touching lever, described touching lever
From the top down through this stopper slot.
Above-mentioned signal triggers the operation principle of device: when the plunger of oil buffer is acted on by elevator car
After moving downward, described touching lever moves downwardly together with plunger；When the touch surface on touching lever contacts with travel switch, stroke is opened
Close and touching lever produced active force horizontally outward, owing to touching lever is matched with in the stopper slot of limit base, and this stopper slot close to
Kink, the active force that touching lever is produced by the most described active force by limit base offsets, so that it is guaranteed that touching lever does not swings,
And reliably, accurately promote travel switch Guan Bi, it is thus achieved that touching signal.
One preferred version of the present invention, wherein, described limit base by for be connected with cylinder body connecting portion, be used for arranging
