Description

Technical Field

[0001] The invention belongs to the technical field of concrete product production, and in particular relates to a grouting mechanism for concrete production and processing. Background Art

[0002] Concrete products are a common building material. They are widely used in the construction industry because of their simple preparation and good structural performance. The existing concrete products are obtained by either on-site casting or prefabrication. Steel cage concrete precast parts are a common concrete precast component, which consists of a steel cage and concrete. The steel cage is a mesh structure formed by high-strength steel bars processed and welded according to design requirements. During the production process, the steel cage is first processed and placed in a prefabricated molding mold, and then concrete is poured into the mold so that the steel cage is completely wrapped in concrete. After the concrete solidifies, the precast part is formed. Steel cage concrete precast parts have good bearing capacity and seismic resistance, and are widely used in bridges, tunnels, subways, water conservancy projects, house construction and other fields, and are often used to speed up construction and improve project quality.

[0003] When existing prefabricated steel cage concrete parts are manufactured, in order to make the prefabricated parts easier to remove from the mold, a certain amount of mold release agent is often sprayed on the inner wall of the mold before pouring concrete into the mold. The existing method uses a spray pot to spray the mold release agent on the surface of the mold, which makes it difficult to form a uniform mold release agent on the inner wall of the cylindrical mold, resulting in the problem that the prefabricated steel cage concrete parts are difficult to demold. In order to ensure that the steel cage is located in the middle of the prefabricated part, the current process usually places a 40mm high concrete pad at the bottom of the mold, places the steel cage on the pad, and finally pours the concrete. Due to the lack of good mechanical bite and chemical bonding between the newly poured concrete and the solidified concrete, the adhesion is poor, and the bonding strength is lower than that of the concrete prefabricated parts cast in one time. When subjected to stress, delamination or peeling may occur. Summary of the invention

[0004] The object of the present invention is to provide a grouting mechanism for concrete production and processing to solve the problems raised in the above-mentioned background technology.

[0026] The mold set 15 includes two arc-shaped plates 151, which are mutually clamped, and the two ends of the outer surface of the arc-shaped plate 151 are fixedly connected with a plurality of limit blocks 152, and the right side of the inner surface of the arc-shaped plate 151 is fixedly connected with a semi-arc sheet 153, and the right side of the semi-arc sheet 153 is fixedly connected with a plurality of clamping seats 154, and the inside of the clamping seat 154 is slidably connected with a T-shaped rod 155, and a compression spring 156 is fixedly connected between the T-shaped rod 155 and the clamping seat 154, and a clamping block 157 is fixedly connected to the inner end of the T-shaped rod 155, and an exhaust discharge valve 158 is fixedly installed on the left part of the upper arc-shaped plate 151.

As the push scraper 91 moves, the concrete inside the mixing shell 7 will enter the interior of the arc plate 151, and the air in the arc plate 151 will be discharged from the exhaust valve 158. When the circular plate 10 contacts the block 157, the block 157 will be pushed to move outward and squeeze the compression spring 156.

At this time, the interior of the arc plate 151 is full of concrete and the steel cage is located in the center of the concrete. After the concrete is initially set, the electromagnet 14 is powered off and the exhaust valve 158 is closed, and the mold group 15 is taken out from the middle of the connecting plate 16. Since the block 157 clamps the circular plate 10, the circular plate 10 is taken out at the same time when the mold group 15 is taken out.

[0028] Working principle:

[0029] When the present invention is used, the multi-stage telescopic hydraulic cylinder 8 is extended to the longest position, so that the pusher 9 is exposed from the stirring shell 7, and the right end of the circular plate 10 is placed in the square hole 93. During the process, the circular plate 10 will push the clamping block 95 to move into the interior of the sliding cavity 92. When the right end of the circular plate 10 completely enters the square hole 93, the plurality of clamping blocks 95 clamp the circular plate 10, and then the multi-stage telescopic hydraulic cylinder 8 is shortened and reset to clamp the two semi-arc pieces 153. Then the semi-arc piece 153 and the limit block 152 are slid into the interior of the middle driving gear 4 and the left driving gear 4, and the limit block 152 is connected to the driving gear The limiting groove of the inner wall of the wheel 4 is in close contact, and at the same time, the right end of the arc plate 151 is in close contact with the left side of the mixing shell 7. The exhaust and discharge valve 158 is at the same height as the movable plate 11. The disc 159 is movably installed on the right side of the inner surface of the arc plate 151. The movable plate 11 is opened, and a proper amount of raw materials for concrete production are added to the inside of the mixing shell 7. The amount of raw materials added will not exceed the semi-arc plate 153. In order to prevent the raw materials from entering the inside of the arc plate 151, the movable plate 11 is closed, and a proper amount of release agent is added to the inside of the arc plate 151 through the exhaust and discharge valve 158;

[0030] The driving member 2 works, driving the transmission shaft 3 to rotate, so that the driving gear 4 drives the transmission gear 5 to rotate. The simultaneous rotation of the three transmission gears 5 drives the mixing shell 7 and the arc plate 151 to rotate, so that the raw materials for concrete production are evenly mixed inside the mixing shell 7, and the release agent is evenly applied to the inner wall of the arc plate 151. The driving member 2 stops rotating, and the exhaust discharge valve 158 and the movable plate 11 are located at the uppermost position. The disc 159 is removed, and the steel cage that can be attracted by the magnet is placed inside the arc plate 151. Then the disc 159 is installed, and the electromagnet 14 is energized to attract the steel cage so that the steel cage and the central axis of the two arc plates 151 are collinear;

[0031] Open the movable plate 11, add a proper amount of lime powder to the inside of the mixing shell 7, close the movable plate 11, the driving member 2 stops working after mixing the lime powder evenly, the exhaust valve 158 opens, the multi-stage telescopic hydraulic cylinder 8 works to push the scraper 91 and the circular plate 10 to move to the left, thereby pushing the mixed concrete to move to the left, and no concrete will remain on the inner wall of the mixing shell 7. With the movement of the scraper 91, the concrete inside the mixing shell 7 will enter the inside of the arc plate 151, and the air in the arc plate 151 will be discharged from the exhaust valve 158. When the circular plate 10 and the block 157 are When in contact, the block 157 will be pushed to move outward and squeeze the compression spring 156. When the circular plate 10 is matched with the middle of the two semi-arc pieces 153, the block 157 will reset to clamp the circular plate 10. The holder 154, the T-shaped rod 155 and the block 157 will be located inside the notch 96. At this time, the interior of the arc plate 151 is filled with concrete and the steel cage is located in the center of the concrete. Since an appropriate amount of lime powder is added to the interior of the concrete, the lime powder can increase the pH value of the concrete and accelerate the hydration process of the cement. The lime powder reacts with water and releases heat, thereby further accelerating the initial setting of the concrete.

[0032] After the concrete is initially set, the electromagnet 14 is powered off, the exhaust valve 158 is closed, and the mold set 15 is taken out from the middle of the connecting plate 16. Since the block 157 holds the circular plate 10, the circular plate 10 is taken out at the same time when the mold set 15 is taken out.
