The quality of pressurizing unit design directly affects the quality of pipe of concrete quality in the tuber, the inequality of pipe of concrete each several part compaction rate often occurs with existing pressurizing unit, and the pipe of concrete of making often exists weak spot, causes the damage of pipe of concrete easily.Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of each of the pipe of concrete that produces closely knit uniform pressurizing unit.
The technical scheme of the present invention's employing is for this reason: the present invention includes main shaft that is driven by unit head and the extrusion head that is arranged on the main shaft lower end; Said extrusion head comprises the corresponding last squeegee roller that is provided with up and down, following squeegee roller; Last squeegee roller is driven by different motor respectively with following squeegee roller; Distribution device is established on last squeegee roller top, and the troweling ring is established in the bottom of following squeegee roller.
Four layers of setting of described pressurizing unit: ground floor: distribution device: distribution device comprises the distribution plate that annular is provided with, and distribution plate is provided with material is evenly flowed to distribution plate drapery panel all around, and the edge of distribution plate is provided with the charging tray of dialling with the flow direction of material squeegee roller; Second and third layer is the corresponding last squeegee roller that is provided with, following squeegee roller; The 4th layer: the troweling ring.
Said pressurizing unit comprises the central shaft that drives troweling ring and following squeegee roller motion and drives the hollow shaft of going up the squeegee roller motion.
The unit head of said driving main shaft is arranged on the guide rail, and main shaft is provided with the supporting member that is connected on the frame.
Advantage of the present invention is: 1) pressurizing unit of the present invention adopts double-deck squeegee roller counter-rotating design, guarantees that steel reinforcement cage is stable in goods, and reduces distortion; And the present invention establishes the cloth distribution plate between last squeegee roller and following squeegee roller, can make concrete flow into the slit between extrusion head and the pipe die uniformly, forms high-quality pipe of concrete; 2) the present invention drives main shaft that pressurizing unit moves up and down and is driven by the unit head that is arranged on the guide rail, has guaranteed can not vibrating of pressurizing unit, guarantees Products Quality; Main shaft of the present invention is provided with some aiding supports simultaneously, improves the rigidity of main shaft, has also further avoided the beat of main shaft in rotating at a high speed, improves Products Quality.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed explanation, so that better understand the present invention.
Apart from cantilever, condition of work is unfavorable for long for main shaft 12.In order to strengthen its rigidity, reduce the beat of main shaft 12 in the rotation at a high speed.This machine has been installed supplemental support 13, and this not only makes the cantilever of main shaft 12 become 2 supportings, and can avoid concrete to contact with main shaft 12, has improved the condition of work of main shaft 12.
Extrusion head is equipped with in main shaft 12 lower ends, and extrusion head adopts double-deck counter-rotating design, is divided into four layers:
1. ground floor is a distribution device; Distribution device comprises distribution plate 3 and the drapery panel 4 and group charging tray 5 that are arranged on distribution plate 3 edges; Wherein drapery panel 4 outward-dipping settings make concrete uniformly to motion all around; Distribution plate 3 is arranged in around the pipe of concrete concrete uniformly, dials charging tray 5 accelerate concrete and flows to squeegee roller uniformly; Establish four fanning strips that are uniformly distributed with 31 around the distribution plate 3 of the present invention, fanning strip 31 is provided with dials charging tray 5, and said group of charging tray 5 comprises the gland 52 that is connected with said distribution plate 3 and be arranged on realizes the scraper plate 51 that concrete flows on the gland 52; All establish drapery panel support 32 around the distribution plate 3 simultaneously, establish said drapery panel 4 on the drapery panel support 32;
2. the second layer is for being rotated counterclockwise squeegee roller 6, compacted concrete tube wall when rotating at a high speed and rising;
3. the 3rd layer is the squeegee roller 7 that turns clockwise down, and powerful extruding makes concrete compaction; In the middle of the two-layer squeegee roller one deck cloth distribution plate 3 is arranged, can make concrete flow into the slit between extrusion head and mould equably, form high-quality pipe of concrete; Cloth distribution plate 3 is for being rotated counterclockwise;
4. last one deck is the troweling ring, and the troweling ring comprises troweling disk body 8 and troweling sheet 9, is used for the troweling tube wall.
Four layers of major diameter extrusion head technical guarantee can not produce the pressure head dead angle: owing to be move toward one another, guarantee that steel reinforcement cage is firm in goods, and reduce distortion that all parts are wear-resisting design.
Extrusion head is bottom-up at the uniform velocity to be promoted, and according to raw material and concrete requirement, sets the rotating speed of cloth wheel and squeegee roller respectively, reaches best squeezing effect.Twin shaft drives, and following squeegee roller 7 is driven by central shaft 1 with the troweling ring, and last squeegee roller 6 is driven by hollow shaft 2, respectively by separately motor-driven, cloth distribution plate 3 and under squeegee roller 7, rotating speed adjustable.The squeegee roller gap is even, does not pile up concrete, and the extrusion head hoisting velocity is adjustable.
