Description
Technical field
The invention belongs to railway machinery field, and in particular to a kind of railway aids in the automatic mud jacking all-in-one machine of vacuum.
Background technology
Railway pneumatic mortar machine is mainly used for bridge prestress pipeline pneumatic mortar, and pipeline pneumatic mortar is most important construction ring in post-tensioning beam
One of section, uses vacuum-assisted grouting technology substantially at present.Existing common squeezing trolley or lack automatic charging Weighing system or
There are feeding to weigh the defects of inaccurate, slurry configurations are random, powder transmission stroke is long；Pipe ends lay equipment integration respectively
Degree is not high, and manual intervention influences greatly, and mud jacking the degree of automation of operations are limited, and causes mud jacking to operate more complicated, slurry pressure injection process
Unstable, the problems such as easily residual air causes not full and Construction Fugitive Dust Pollution serious at mud jacking end, it is in particular in：
（1）The problems such as traditional approach is to lean on screw auger or artificial loading mode in railway mud jacking, and dust pollution is serious.
（2）Since construction needs, vaccum-pumping equipment and mudjack are respectively placed in beam body both ends at present, by artificial and system
Control respectively, the degree of automation is low, and technique conversion and operation are unmanageable, influence construction quality.
（3）, it is necessary to carry out weighing preparation to slurry by recipe requirements in pumping of prostressed duct operation, it is desirable to water and powder
The weighing error of material should be controlled in ± 1%, current blanking weigh mode be all under high-speed stirred tank stirring blanking and
Weigh, especially the slurry to measure control several times, there are larger error, directly affects slurry quality.
（4）Mudjack is the important equipment of pumping of prostressed duct operation, currently used continuous mudjack --- screw rod
Pump easily burns out stator when being operated without slurry, also will more exchanging rotor when using 80-100 piece box beam mud jacking even if careful maintenance
Stator, overall process life cycle is short, and the screw pump in addition used at present can not also record mud jacking slurry quantity.The single cylinder column used

（5）It is general at present during prestressed concrete beam pipeline pneumatic mortar operation to improve the mud jacking plumpness and compactness of slurry
Vacuumized all over using one end, the technological process of other end pressure injection slurry.I.e. under seal for pipe joints state, first carry out vacuumizing auxiliary
Operation, after vacuum meets code requirement, carries out slurry pressure injection, when slurry reaches pulp starting mud jacking system from mud jacking end
During end, vacuum pump is turned off, and slurry is discharged in trash receptacle, when the slurry of discharge reaches basically identical with mud jacking end slurry
Fluidity when, the valve of slurry output end is closed, into automatic pressure-maintaining voltage stabilizing and micro benefit slurry stage.Overall process is not implemented in the technique
Automatically control, and operation is more complicated, if control is improper, there is also the accident that slurry sucks vacuum pump and damages；At the same time
Mud jacking end non air exit hole, easily causes empty, not full near stock inlet；Pipeline pneumatic mortar should be carried out after tensioning as early as possible, mud jacking should
Slowly, uniformly, be carried out continuously, in order to ensure the quality of mud jacking, it is necessary to vacuumize, smoothly to be pressed in time after vacuumizing
