The model utility content: the purpose of this utility model is to overcome the deficiencies in the prior art, designs the cooperation ratio of a kind of cement slurry and additive, can carry out the stepless proportioning two fluid grouting pump that any proportioning is adjusted at any time according to the construction process needs.
The purpose of this utility model is achieved in that a kind of stepless proportioning two fluid grouting pump, by the driving mechanism that is installed on the frame, be linked in the gear-box of driving mechanism through power gear, being linked in the identical suction paste system of two cover slurry cylinder cylinder diameters separately through two synchronous double-action mechanism A, the B that cover connecting rod-crosshead-piston rod is formed forms, it is characterized in that the power gear center fixation in the gear-box has transmission shaft
Connecting rod one end of double-action mechanism A, B is linked in side by side two bars of fixing, being bound up on the transmission shaft through bearing or bearing shell and connects eccentric wheel, two bars connect the eccentric wheel center of rotation with respect to the maximum eccentricity of transmission shaft center of rotation corresponding to two cover connecting rod-crosshead-piston rod ranges.Its design effect is that transmission shaft-two bar connects eccentric wheel and rotates a week, cement, the cement of each suction of piston rod-piston-slurry cylinder in the additive slurry suction system, additive slurry that two cover connecting rod-crosshead-piston rods connect respectively.
It is identical with respect to the maximum eccentricity of transmission shaft center of rotation that two bars of synchronous double-action mechanism A, B connect eccentric center of rotation.Its design effect is the effect that the identical suction paste system of two cover slurry cylinder cylinder diameters is produced suction slurry same amount.
The bar of connecting rod one client link of double-action mechanism B connects eccentric wheel and is linked in the eccentric wheel that is coupling that is fixed on the transmission shaft through mono-directional overrun clutch, and the eccentric wheel center of rotation that is coupling is that this bar connects the eccentric wheel center of rotation with respect to 1/2nd of the maximum eccentricity of transmission shaft center of rotation with respect to the throw of eccentric of transmission shaft center of rotation; The bar of double-action mechanism B connects eccentric side has internal-gear through bolt, and the internal-gear inner chamber is engaged with the external tooth gear that is socketed on versatilely on the transmission shaft.Its design effect is:
After start, the eccentric wheel that is coupling connects eccentric wheel by the forward drive bar of mono-directional overrun clutch and rotates a week, the piston rod-piston-additive slurry of slurry cylinder suction in the additive slurry suction system that connecting rod-crosshead-piston rod connects.
When the cooperation ratio of cement slurry and additive being adjusted according to the construction process needs, after only needing to shut down, reach set angle with external force reverse rotation external tooth gear, this set angle is corresponding with the selected cooperation ratio of cement slurry and additive: the selected cooperation ratio as cement slurry and additive is 1: 0 o'clock, and corresponding set angle is 180 degree; The cooperation ratio is 1: 0.25 o'clock, and corresponding set angle is 120 degree; The cooperation ratio is 1: 0.5 o'clock, and corresponding set angle is 90 degree; The cooperation ratio is 1: 0.75 o'clock, and corresponding set angle is 60 degree; The cooperation ratio is 1: 1 o'clock, and corresponding set angle is 0; Because above-mentioned internal-gear-bar connects eccentric linkage structure and the eccentric throw of eccentric that is coupling is half the structural relation that bar connects the eccentric wheel maximum eccentricity, determined arbitrarily corresponding cooperation ratio can both obtain external tooth gear and turned over corresponding set angle along the internal-gear inner chamber, when Fig. 2,3 had provided external tooth gear rotation 180 degree, 0 (rotating), the rotatingshaft-eccentric wheel-bar that is coupling connect the view of eccentric wheel-connecting rod.The performance of mono-directional overrun clutch determined to allow internal-gear-bar connect the angle of the eccentric wheel setting that and then the external tooth gear reverse rotation is identical simultaneously, and to connect eccentric wheel be corresponding value of having dwindled with respect to the maximum eccentricity of rotatingshaft thereby changed bar.
After restarting, rotatingshaft-the eccentric wheel that is coupling forward drives bar through mono-directional overrun clutch and connects eccentric wheel, bar connects eccentric wheel then by the corresponding maximum eccentricity drivening rod-crosshead-piston rod after changing, and the piston rod-piston in the additive slurry suction system that connects in the slurry cylinder by new shortening the stroke distances operation, so how much determining of suction additive slurry, thereby obtained in the effect of selecting synchronous suction cement slurry of cooperation ratio and additive slurry by the new piston stroke after changing.
In sum, the arbitrarily corresponding cooperation ratio of cement slurry and additive slurry can both obtain corresponding external tooth gear reverse rotation and adjust angle, thereby has realized carrying out the stepless proportioning dual-fluid synchronous slip casting that any proportioning is adjusted at any time according to the construction process needs.
The two fluid grouting pump of the utility model and prior art is in order to realize different proportionings, and the slurry cylinder that need replace with different-diameter is compared, and is both easy to operate, saved cost and man-hour again.
