Description
Technical field
The invention belongs to engineering machinery field, and in particular to a kind of lorry-mounted crane active rollover prevention system and method.
Background technology
Lorry-mounted crane is that hoisting operation mechanism is installed on heavy-duty freight car, due to its tool as one of special vehicle
Standby lifting, loading, maneuverability particular advantages, be widely used in communications and transportation, civil construction, electric power, telecommunication, field work,
The field such as stone material industry and harbour, with the high speed development of national economy and the fast lifting of living standards of the people, hand labour by
Step is substituted by mechanization work, and the bigger market demand is brought to lorry-mounted crane.
Country requires more and more tighter to construction safety, and also more and more higher is required to the security performance of lorry-mounted crane, related
8 tons of clear stipulaties and above equipment must mounting torque limiter systems for law.It is different with the automobile chassis of car lifting in addition
In the full Terrain Cranes, the transformation of the way of its generally use body with frame forms, almost without for doing special change with crane
Enter, therefore the lifting operation stability of vehicle is hardly resulted in and is completely secured, the safety problem including tumbling is more prominent.Perhaps
More companies are studied for anti-tipping problem, more stresses got on the bus using monitoring hoisting process, prejudge and control and get on the bus
Arm stopping acts or adjustment direction of action, speed etc. reach anti-tipping purpose, rarely have proposition by supporting leg stress and under
Car axle positioning state integrates global scope assessment and anticipation vehicle lifting operation status, if monitor value is tumbled threshold more than setting
Value, there is precarious position, stopping is got on the bus, and actively individually four vertical telescopic amounts of control change posture of getting on the bus simultaneously for action, eliminate danger
Dangerous state.
It is mostly by detecting hydraulic leg oil cylinder working-pressure, vertical currently for the anti-tipping measure taken of lorry-mounted crane
Supporting leg determines whether in a safe condition with ground Interaction Force, or determines whether to locate based on modes such as limiters of moment
In safe condition, anti-tipping method mentioned above be mostly control get on the bus Lift-on/Lift-off System stop motion, send alarm reply with
The precarious position of car crane, and rarely have and propose the safe to use of further actively anti-tipping measure lifting lorry-mounted crane
Property.Control Lift-on/Lift-off System stop motion of getting on the bus, send precarious position automaticity, the safety of the reply lorry-mounted crane such as alarm
Property it is low, the risk of maloperation be present, belong to passive anti-tipping.
The content of the invention
, can in view of the deficiencies of the prior art, the present invention provides a kind of lorry-mounted crane active rollover prevention system and method
Automatically, safely realize that lorry-mounted crane is actively anti-tipping.

Device, support leg pressure sensor Real-time Feedback parameter calculate lifting operation process carload bias of inclining and account for the maximum allowable bias ratio that inclines
Example, while comprehensive anticipation is tumbled direction.
(3)The carload calculated in real time is inclined anti-tipping threshold value of the bias not less than default, active rollover prevention system
Do not work, crane works on, and controller continues analysis and calculated.
(4)The carload calculated in real time incline bias exceed default anti-tipping threshold value, now system start to alarm,
Stopping is got on the bus all actions, and the vehicle fed back according to anti-tipping controller inclines folk prescription to each vertical leg of active independent control
Vertical drive oil cylinder expanding-contracting action, inclined side cylinder elongation of inclining, inclined side of inclining shortens to side cylinder, actively adjust four supporting legs by
Power state and body gesture, until it meets anti-tipping threshold requirements.
Compared with prior art, this patent provides a kind of lorry-mounted crane active anti-tilting apparatus and method, prevents with current
Tipple is different, and it completes detected value with preventing in a control unit mainly by detecting supporting leg stress and body gesture
Four vertical legs of control complete corresponding expanding-contracting action response and stop all actions of getting on the bus after design of tumbling threshold values contrast, actively
Vertical leg stress and vehicle lateral inclination and inclination in the running direction posture are adjusted, realizes that lorry-mounted crane is actively anti-tipping
Purpose, the safe and reliable property of this method are high, simple, applicable.
