Description

Core concrete member making machine for rush repair engineering

Technical Field

The invention belongs to the field of rush repair of engineering, and particularly relates to a cored concrete member making machine for rush repair engineering.

Background

The hardening of concrete is divided into two stages, a setting stage and a strength increasing stage. The national standard stipulations are as follows: the initial setting time of the portland cement is not earlier than 45min, and the final setting time is not later than 6h and 30 min; the initial setting time of the ordinary portland cement is not earlier than 45min, and the final setting time is not later than 10 h. After final setting, the concrete begins to increase in strength, and can basically reach the designed strength by 28 days after pouring. The concrete strength test evaluation is based on the concrete strength test evaluation. However, the increase in concrete strength is not terminated, but is slowly increasing. After half a year or even a year, the strength has also increased.

In the construction with a tighter construction period, the shorter the construction period is better, and sometimes, a concrete prefabricated part is buried in the construction in advance, and then new concrete is added to reduce the construction time of the concrete. When the volume ratio of the concrete prefabricated part is too large, cracks are easy to appear at the joint of newly added concrete and the prefabricated part in the use process after hardening. At present, a process method adopting a pellet-shaped prefabricated member is adopted, but the pellet-shaped prefabricated member is directly added, the contact positions of the pellet-shaped prefabricated members are more, and the naturally hardened concrete added later is discontinuous and is easy to crack. It is desirable that the naturally formed concrete be able to encapsulate the preform so that the naturally hardened concrete is largely continuous, increasing strength. At present, the process is not popularized, and the outer layer of the pill-shaped concrete is coated with the plastic concrete manually. Meanwhile, the existing pill making machine cannot automatically discharge the pill-shaped concrete part, manual carrying is needed in a construction site, and the labor cost is too high.

Disclosure of Invention

The invention aims to provide a cored concrete member machine for rush repair engineering, which aims to solve the problem that a pill-shaped concrete member cannot be automatically discharged in the prior art.

In order to achieve the purpose, the basic scheme of the invention provides a cored concrete member making machine for rush repair engineering, which comprises an inclined cylinder body, wherein a shaft helical blade is rotationally connected in the cylinder body, and the edge of the blade with the shaft helical blade is provided with an arc-shaped forming groove.

The first optimization scheme is as follows: the blade edge of the spiral blade with the shaft is provided with a plurality of slag discharge openings.

And the second optimization scheme is as follows: the slag discharge opening is in a strip shape.

And the optimization scheme is three: the two side end surfaces of the slag discharging opening are in a convex curved surface shape which inclines towards the slag discharging opening.

And the optimization scheme is four: and one end of the forming groove, which is close to the inner wall of the cylinder body, is provided with a fillet.

And the optimization scheme is five: the end part of the cylinder body is provided with an inclined rolling-out slideway.

And the optimization scheme is six: the roll-out chute is plate-shaped.

The optimization scheme is seven: the cross section of the roll-out slideway is arc-shaped.

And the optimization scheme is eight: the end part of the barrel is fixedly connected with a protective cover for preventing material falling, the protective cover is communicated with a linear rolling-out slideway, and the rolling-out slideway is tangent to the barrel.

The beneficial effect of this basic scheme lies in: 1. the blades with shafts are provided with arc-shaped forming grooves, so that concrete parts can roll in the forming grooves to form balls more easily, and the construction and use are facilitated.

2. The spiral blade with shaft and the inclined cylinder cooperate to function like a spiral conveyer to discharge the prepared pill-shaped concrete part out of the cylinder.

3. The strip-shaped slag discharge opening can prevent waste materials in the pelleting process from being discharged out of the barrel along with the pelletized concrete part, and additional screening work after pelleting is avoided.

4. The convex surface shape of the end surfaces at the two sides of the slag discharging opening enables the concrete part to smoothly span the slag discharging opening without leaving dent marks on the pill body.

5. The arrangement of the fillet reduces the possibility that waste residues stay on the blades of the axial helical blades.

6. The rolling slideway with the arc-shaped cross section enables the ball-shaped concrete part to roll out along the rolling slideway when rolling out.

7. The shield prevents the pill-shaped concrete part from falling off the equipment when rolling out.

The upper part of the cylinder body 1 is provided with a plurality of dry concrete filling openings 5, the filling openings 5 are communicated with a concrete input pipe, and the input pipe is communicated with a concrete delivery pump. (the power mechanism, the feed pipe and the concrete delivery pump are not shown in the figure)

As shown in fig. 2 and 5, the edge of the helical blade 3 is integrally formed with a circular arc-shaped forming groove 8, and one end of the forming groove 8, which is close to the inner wall of the cylinder 1, is rounded. The edge of the helical blade 3 is integrally formed with a plurality of slag discharge openings 7, and the slag discharge openings 7 are strip-shaped. Both side end surfaces of the slag discharge opening 7 are formed in a convex curved surface shape inclined toward the slag discharge opening 7. The curved surfaces at the two sides of the slag discharging opening 7 are symmetrical.

As shown in fig. 1 and 3, a protective cover 6 for preventing material falling is fixedly connected to the right end of the cylinder 1, a linear rolling-out slideway 10 is communicated with the protective cover 6, and the rolling-out slideway 10 is tangent to the cylinder 1. The cross section of the roll-out ramp 10 is circular-arc shaped.

The method is used for manufacturing the pill-shaped concrete part with internal hardening and certain plasticity on the outside and is used for rush repair engineering. Starting a power mechanism to enable the spiral blade with the shaft to rotate, inputting concrete with the slump of 90-100 mm and the content of broken stones below 5mm into the barrel body 1 by using a concrete transportation pump, and putting the formed (dried) pill-shaped concrete part into the barrel body 1 from the feeding port 2.

Under the action of the helical blades 3, the pill-shaped concrete part rotates in the forming groove 8 and moves towards the right end of the cylinder 1. Because the concrete with the slump of 90-100 mm has certain fluidity and viscosity, the injected concrete is wrapped outside when the pill-shaped concrete part rotates, and the pill-shaped concrete part rolls into a pill shape (spherical shape) under the action of the arc-shaped forming groove 8.

As shown in fig. 4, when the pellet-shaped concrete piece rolls to the slag discharge opening 7, when the pellet-shaped concrete piece crosses the slag discharge opening 7, the pellet-shaped concrete piece collides with the end portion on one side of the slag discharge opening 7, and air bubbles brought in when the concrete outside the pellet-shaped concrete piece is wrapped are discharged after the collision, so that the pellet-shaped concrete piece is more compact. Meanwhile, the end surfaces of two sides of the slag discharging opening 7 in the shape of the convex curved surface enable the concrete part to smoothly cross the slag discharging opening 7 without leaving dents on the pellet body. The concrete not attached to the pelletized concrete piece falls to the lower left portion of the cylinder 1 through the slag discharge opening 7. The discharged pill-shaped concrete piece rolls down along with the roll-out chute 10.
