The utility model squeezing trolley integrate automatic charging, weigh automatically, high stirring at low speed, pumped slurry, be used for Mix cement mortar and other slurries.Highway, railway construction engineering and part Production in Chemical Plant is can be widely applied to use.Tool Have conveniently moving, automaticity it is high, it is simple to operate easy to learn the features such as.

This squeezing trolley is designed as movable type, and every point of part of the equipment high-speed stirred highest can stir 400 kilograms of slurries, often Hour can stir 2500~6000 kilograms.Stirring at low speed storage vat is additionally provided with, 900 kilograms or so of slurry can be stored.High low speed Stirring is engaged, and real can be uninterruptedly fed to mud jacking equipment, improves engineering efficiency.

This bassinet structure is novel, and production efficiency is high, mixing quality is good.Product quality complies fully with TB/T3192-2008《Railway Post stressed concrete beam pipe mudjacking technical conditions》Requirement.

High-speed stirred mechanism is fixed on tripod by weighing sensor 31, through micro computer observing and controlling, realizes the standard of dispensing Really put into.

With reference to shown in Fig. 9, during the intelligent big mud jacking equipment mud jacking of the utility model embodiment, the past pan feeding of employee successively Grouting agent and cement are added in bucket, system starts three phase electric machine, and motor drives screw rod, and feed powder is passed to high-speed stirred by helical blade The material porch of machine, feed powder is fallen into homogenizer, and motor rotates the rising for driving feed powder improper, so as to realize feeding Automatic charging.

System controls the component and ratio of feed powder by weighing detection and motor, so that improving operating efficiency ensures slurries Quality.

Main shaft drives blade low speed rotation in agitator when stirring at low speed system works, and the slurry in bucket is stirred more It is full and uniform, while preventing that locally micro- coagulation phenomena slurries occurs.

Starting mode of pump after electrical power, will set in the desired amount of water injection high-speed stirred bucket, the water of stirring is to pass through Weighing apparatus are measured, and measurement data is then passed to control centre, the upper water time was controlled by control centre.

The entrance of the pneumatic mortar machine of automatic mud jacking system is connected on the discharging opening below stirring at low speed bucket, as shown in fig. 6, mud jacking When time reaches predetermined value, pneumatic mortar machine starts, pneumatic mortar machine midge, mud jacking screw pump mud jacking, just have in pipeline slurries outflow so as to Complete to work to the slip casting of beam duct.Pressure during mud jacking can see numerical value by control system computer panel, can also be Directly observe pressure gauge numerical value in the loop end of mud jacking.By the pressure high-low limits of setting, system can be made automatically into pressurize shape State, and in the dwell time to rear automatic closing pneumatic mortar machine.

As shown in fig. 7, weighing system start-up operation when, according to sets requirement input glue aspect ratio, system-computed water, The weight ratio of cement, grouting agent.The subsequent former feeding of system control material, is adjusted doses by weighing sensor, is weighed using two groups Sensor just can effectively avoid claiming because treasure failure causes water-cement ratio confusion phenomena to occur, two groups of mutual schools of weighing sensor Core, weighing sensor is related to the quality problems of slurries, if sensor goes wrong, and water-cement ratio just occurs uncertain, leads Cause the unqualified of slurries.

As shown in fig. 6, serum recycle valve, serum recycle pipe, automatic mud jacking system and stirring at low speed system composition slurries are followed Loop back path system.

The work of serum recycle circuit system is system in pressure maintaining period is carried out, and this is one and essential is recycled back to Road, when system carries out pressurize, serum recycle valve is automatically opened up, screw pump mud jacking, and slurries return to low speed from the output of serum recycle pipe Agitator, effectively prevention slurries caking or local coagulation.

Control centre's system is one of important composition of whole system, and its stabilization is to weigh the index of mass of system.Electricity The peopleization that the safety on road, the safety of motor, the precision controlling of water-cement ratio, system are used is closely bound up with control centre.Cause This, my company requires more to rationalize when from electrical equipment by strict selection, during circuit design, circuit modular, and one is It is easy to Inspection and maintenance in the future, two be the confusion for reducing control, makes system work smooth efficiently.System is provided simultaneously with manually individually Service behaviour, i.e. can press standard operation mud jacking process manually, is so easy to test acquisition control.

The effect of standby power system in order that equipment when power-off also can normal work, stand-by power supply can use 90-120min of duration, the features such as circuit has automatic detection energization, electric leakage, power conditions.

Increase slurry fluidity automatic checkout system can more effectively reduce the influence of human factor, in the process of mud jacking In, should not timing indefinite batch mobility-detected is carried out to the slurries of making, effectively control grind slurries quality.Mobility is examined Survey is carried out before mud jacking, it is to avoid unqualified slurries are flowed into beam duct.

High pressure cleaning system is after the completion of mud jacking, and employee directly can be cleaned with high-pressure cleaning system to equipment, prevents Only remaining slurry is not discharged cleaning and solidified for a long time in agitator, pipeline, to delaying job schedule when enabling again in the future.It is equipped with clear System is washed so that equipment is more perfect, it is durable.

The intelligent big mud jacking equipment of the utility model is according to the new bridge gauge of highway and railway TB/T 3192-2008《After railway Open method prestressing force mixed mud beam pipeline pneumatic mortar technical conditions》, the Ministry of Railways《The provisional technology of Line for Passenger Transportation prestressed concrete precast beam Condition》Related request be designed.Construction technology can be monitored in real time, record, preserve, with can not disorderly change Construction results, the function of deleting construction note.The system is integrated with existing pneumatic mortar machine automation, practical, simplification, convenient purification Outside Deng common feature, the distinctive work(such as standby power system, weighing instrument nucleus correcting system, slurries fluidity detecting system have also been increased newly Use characteristic.With this, it is ensured that slurrying, the promptness of mud jacking, the accuracy of glue ratio and the qualification of slurries.It can break away from outer simultaneously The restriction of boundary's condition smoothly completes mud jacking and has suffered journey.This Intelligent mud jacking machine more effectively improves construction project quality, and reinforcing is managed, Improve engineering.
