Description

A kind of lorry-mounted crane rollover prevention system and method
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.
In order to realize foregoing invention purpose, the present invention uses following technical scheme:A kind of lorry-mounted crane is actively anti-tipping System, including supporting leg condition monitoring system, vehicle bridge condition monitoring system, anti-tipping controller, landing leg hydraulic cylinder extension and contraction control valve, It is characterized in that:The pressure information for the vertical leg that front side support leg pressure sensor and rear side support leg pressure sensor detect passes Supporting leg condition monitoring system is passed, the displacement information that propons displacement transducer and back axle displacement transducer detect passes to vehicle bridge Condition monitoring system, supporting leg condition monitoring system, vehicle bridge condition monitoring system respectively pass to pressure information and displacement information Anti-tipping controller, data processing is carried out by anti-tipping controller and drives landing leg hydraulic cylinder extension and contraction control valve, and then driven not With cylinder action corresponding to vertical leg, to adjust different vertical supporting leg stress and body gesture.
Propons displacement transducer and back axle displacement transducer are collectively referred to as axle positioning sensor;Front side support leg pressure sensor Support leg pressure sensor is collectively referred to as with rear side support leg pressure sensor.
First pressure detection unit, second pressure detection unit, the 3rd pressure sensing cell, the 4th pressure sensing cell point Yong Yu not detect vertical leg before the right side, left front vertical leg, it is right after vertical leg, the pressure of left back vertical leg;First displacement Detection means, second displacement detection means are propons displacement transducer, and triple motion detection means, the 4th displacement detecting fill Put, the 5th displacement detector, the 6th displacement detector are back axle displacement transducer.
Lift pedestal to be arranged on automobile chassis vehicle frame, horizontal support legs are arranged on lifting base interior, and horizontal support legs are in liquid It can be connected under cylinder pressure driving to overhanging so as to obtain vertical leg to external expansion, vertical leg with horizontal support legs.
A kind of anti-tipping method of lorry-mounted crane active, comprises the following steps:
(1)The action of cross cylinder and Vertical Cylinders corresponding to each vertical leg is controlled by operation handle, until vertical branch Leg establishes locking vertical leg hydraulic circuit after supporting relation with ground;
(2)Controller is according to the wheelbase of current state, wheelspan, the crane chassis parameter of supporting leg span and axle positioning sensing 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.
