Description
Technical field
The present invention relates to the buffering stoppers of elevator, and in particular to a kind of signal triggering dress of hydraulic buffer of elevator
It puts.
Background technology
The oil buffer of elevator is set to the bottom of elevator, slows down sedan-chair using the damping force of liquid flowing
Impact when compartment is fallen, and make its reset using spring.The oil buffer is mainly triggered by cylinder body, plunger and signal and filled
Composition is put, wherein, form the main body of buffer together with the cylinder body and plunger combination, the signal trigger device is for detecting
The downward storke of plunger, when plunger runs down to certain position with car, the signal trigger device sends out trigger signal,
And it send to control system.The signal trigger device is made of travel switch and touching lever, wherein, the travel switch is set to cylinder
On body, the upper end of plunger is fixed in the upper end of the touching lever, and the lower end of touching lever extends downward into the top of travel switch, touching lever
Lower end is equipped with inclined touch surface；Touching lever is moved downward with plunger during work, is opened when the touch surface on touching lever contacts the stroke
Guan Shi, travel switch obtain trigger signal.
Existing signal trigger device has the following disadvantages：
1st, since touching lever is the upper end fixation free cantilever design in lower end, and touching lever is usually relatively long, when on touching lever
When touch surface is contacted with travel switch, active force that travel switch generates touch surface promote the lower end of touching lever in the horizontal direction to
Outer movement, the defects of bringing, are, on the one hand, so that Time delay, the triggering stroke increase that touching lever is run downwards in other words,
So as to car be controlled to stop in time, safety is affected；On the other hand, shaking is generated when touching lever contacting travel switchs,
So as to influence the stability of trigger signal.
2nd, touching lever is continually deformed in use by the extruding of travel switch, and the later stage top that works long hours holds
Fracture easily occurs or generates expendable lateral deformation, while also results in Time delay and even fails, the use of touching lever
Short life, and there are security risks.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of signals of elevator oil buffer to touch
Transmitting apparatus, touching lever will not generate shaking when which works, and have many advantages, such as safe and stable property, good reliability.
The purpose of the present invention is realized by following technical solution：
A kind of signal trigger device of elevator oil buffer, including travel switch and touching lever, wherein, the stroke
