Column status monitoring and prevent the unexpected locking system that bounces back, wherein the inner sleeve, displacement monitor, prevents accident at outer tube
Retraction locking system is complete set device, is followed successively by inner sleeve according to positional relationship, outer tube, monitoring device, prevents accident
Bounce back locking system.Be welded with lock block on one face of the inner sleeve tube wall, lock block welding manner is single-row or two column,
Equidistantly, length and inner sleeve are isometric;Detection rack gear is installed, rack shapes are the equidistant dentation of stripe shape, the small spacing of tooth on tube wall face
Greatly, length and inner sleeve are isometric;The outer sleeve bottom, which is equipped with, prevents the unexpected locking system that bounces back, monitoring inductor, prevents
It is unexpected that retraction locking system be installed on a face bottommost of column external stent, and monitoring device inductor installs another face most
Bottom.
Present pre-ferred embodiments are when it is implemented, its structure construction and working principle are: structure construction includes: installation branch
Frame, electromagnetic draw bar, angle push-pull rod, locating sleeve, movable locking snap-gauge, driven roller, movable locking in locking snap-gauge
Snap-gauge sliding slot, movable locking snap-gauge compression spring, wire rope pulley, wirerope, wirerope connecting link pin, angle push-pull rod are drawn
Power tension spring, draft regulator and adjuster connecting link pin composition.Working principle is: when locking system does not work, electromagnetic draw bar not
It is powered, under the action of angle pushes and pulls draw-bar pull tension spring, angle push-pull rod stretches out, and passes through driven roller in movable locking snap-gauge
Effect, movable locking snap-gauge, which is jacked up, to be retracted, and leaves and keep certain interval, column with lock block on column inner sleeve
Keep normal stretching motion state;When monitoring device detects that internal and external casing generates displacement, issues electric signal and use electromagnetism
Pull rod obtain it is electric pull back, angle push-pull rod retract, movable locking snap-gauge is under the action of compressed spring, movable locking snap-gauge
It stretches out, and pushes up onto the tube wall of inner sleeve, until being stuck on the lock block on column inner sleeve tube wall, thus locking connecting bridge
Lifting column internal and external casing continues to bounce back, i.e. termination connecting bridge descending motion;Achieve the purpose that the uncontrolled decline of locking connecting bridge.
The connecting bridge monitoring system, which is provided with, works normally indicator light and unexpected retraction locking acoustic-optic alarm, installation
It wakes up on destination locations in connecting bridge operation panel, is observed convenient for connecting bridge operator.When connecting bridge normally issues lifting instruction
When (as manual operation or automatic leveling work when), monitoring device disconnect power supply is not devoted oneself to work, power supply green indicator light does not work;
When there is no (when working such as manual operation or automatic leveling), monitoring system investment is worked normally when issuing lifting instruction for connecting bridge
State, green indicator light are bright;At this time, when such as monitoring device monitors that lifting column internal and external casing surprisingly bounces back, inductor is monitored
Electric signal can be sensed and issue, the movable locking snap-gauge of triggering locking system stretches out, until being stuck in the locking gear of inner sleeve welding
On block, stop retracting motion, while red acoustic-optic alarm is loud.
By said mechanism asking for uncontrolled decline is unable to monitor and prevented to solve current connecting bridge lifting column
Topic, above scheme accomplish on original connecting bridge product it is easy for installation, be easy implementation, high reliablity, using the superiority such as safe
Energy.
In conclusion the invention discloses a kind of connecting bridge lifting columns to monitor unexpected retraction locking system, wherein rising
Dropping includes inner sleeve, outer tube on column, displacement detecting inductor and locking system is equipped on the outer tube, described
Inner sleeve is equipped with lock block and detection rack gear, when the displacement detecting inductor detects that detection rack gear is subjected to displacement,
It will start locking system, locking cooperated by the locking system and lock block, avoids lifting column from bouncing back, through the invention
In connecting bridge in unartificial lifting rebound phenomenon can occur for the locking system, and timely locking avoids that accident occurs, and protects
The safety of the barrier person and aircraft.
It should be understood that the application of the present invention is not limited to the above for those of ordinary skills can
With improvement or transformation based on the above description, all these modifications and variations all should belong to the guarantor of appended claims of the present invention
Protect range.
