The utility model can realize the pipe core molding and protective layer manufacturing of the prestressed steel cylinder concrete pipe, can realize mechanical feeding and vertical vibration molding, and has the characteristics of good product quality, high production efficiency and low labor intensity.

[0004] But there is also a problem: after the tube core is formed, when the outer mold is taken out, due to the uneven opening and closing of the mold (the mold is elliptical), the bottom of the mold will cause radial friction to the tube core. Utility Model Content

[0005] This solution provides a tube core mold with end face protection to solve the problem of uneven opening and closing of the mold.

[0006] The present invention provides a tube core mold with end face protection, comprising a base; an outer mold: the outer mold is coaxially detachably fixedly connected to the base; an inner mold: the inner mold is coaxially arranged with the outer mold, and the inner mold is coaxially detachably fixedly connected to the base; a steel cylinder: the steel cylinder is located between the inner mold and the outer mold, and the steel cylinder is coaxially detachably fixedly connected to the base; a top cover: the top cover is used to clamp the outer mold, the steel cylinder and the inner mold; the top cover comprises: a cover body: the cover body cooperates with the inner mold; reinforcing ribs: the reinforcing ribs are fixedly connected to the cover body, and the reinforcing ribs are located between the steel cylinder and the outer mold, a plurality of the reinforcing ribs are provided, and the plurality of reinforcing ribs are distributed in a circle with the cover body as the center, the reinforcing ribs are provided with sockets, and the sockets cooperate with the steel cylinder; a first steel ring: the first steel ring is fixedly connected to the reinforcing ribs, and the first steel ring is in contact with the outer mold.

[0007] The principle of this scheme is that the operator first places the base, then places the inner mold on the base, and locks the inner mold, then installs the steel cylinder with steel sockets on the base, then places the outer mold on the base and locks it, and finally installs the top cover, the reinforcing ribs of the top cover clamp the outer mold and the steel cylinder, the first steel ring contacts the outer mold to stabilize the outer mold, the socket can be inserted into the steel cylinder with steel sockets to stabilize the steel cylinder, the cover clamps the inner mold to stabilize the inner mold, and the top cover clamps the inner mold, the steel cylinder with steel sockets and the top of the outer mold in turn to complete the installation. The operator starts to pour concrete, so that the concrete flows evenly into the gaps between the inner mold and the steel cylinder, and between the steel cylinder and the outer mold to form the concrete pipe core.

[0008] After solidification is completed, the outer formwork is manually loosened, the top cover is lifted off, the inner formwork is loosened, the inner formwork is lifted off, the outer formwork is lifted off, and the formed steel cylinder concrete pipe is lifted off to complete the construction.

[0009] The beneficial effect of this solution is that: this solution stabilizes the top of the outer mold by strengthening the vertical reinforcement and the first steel ring, so that it is not easy to deform during the pouring process, resulting in the outer mold being scratched on the concrete pipe core when it is taken out.

[0010] Furthermore, it also includes a second steel ring, which is fixedly arranged coaxially with the first steel ring and is located below the first steel ring. The second steel ring further stabilizes the outer mold, reduces the distance between the top cover and the concrete end face, and thus protects the end face from friction and collision with the outer mold.

[0011] Furthermore, it also includes a concrete discharge cone, the cover body is provided with an observation vent, and the concrete discharge cone is rotatably connected to the observation vent. When the operator pours concrete on the concrete discharge cone, the concrete will fall to a designated position due to gravity, preventing the concrete from falling to other places.

[0012] Furthermore, it also includes a vibrator, the shaft of which is fixedly connected to the concrete discharge cone, and the vibrator is arranged at the observation vent. When pouring concrete, the vibrator is started, and the vibrator causes the concrete discharge cone to vibrate slowly, and the concrete falls quickly into the designated position under the action of gravity and centrifugal force. This mechanism can speed up the concrete discharge speed and prevent the concrete from adhering to the concrete discharge cone.

[0013] Furthermore, the cover body is provided with an extraction ring, which can facilitate the operator to control the machine to take the cover body.

[0014] Furthermore, the base is in a stepped shape, which can facilitate the operator to accurately place the outer mold, the steel cylinder and the inner mold. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] Basically as attached Figure 1 , Figure 3 As shown:

[0020] The present solution provides a tube core mold with end face protection, comprising an outer mold 1, a base 3, a steel cylinder 4, an inner mold 5, a top cover 6, and a concrete discharge cone 7.

[0021] The outer mold 1 of the mold forms a closed space on the periphery so that the poured concrete can harden in a predetermined shape to form the required structure or component. It is coaxially arranged with the inner mold 5, and the diameter of the outer mold 1 is larger than that of the inner mold 5. The steel cylinder 4 is formed by spiral welding of cold-rolled steel plates and needs to pass a water pressure test. The base 3 is stepped. The stepped base 3 can facilitate the operator to accurately place the outer mold 1, steel cylinder 4 and inner mold 5. The outer mold 1, steel cylinder 4 and inner mold 5 are all fixed to the base 3 in the stepped position by bolts.

[0022] As attached Figure 2 , Figure 3 As shown:

[0023] The top cover 6 includes a cover body 14, a reinforcing rib 13, a first steel ring 10 and a second steel ring 9: the cover body 14 is the same size as the inner mold 5, the reinforcing rib 13 is fixedly connected to the cover body 14, and the reinforcing rib 13 is located between the steel cylinder 4 and the outer mold 1. There are 16 reinforcing ribs 13, and the 16 reinforcing ribs 13 are distributed in a circle with the cover body 14 as the center. Each reinforcing rib 13 is provided with a socket 11, and the socket 11 is the same model as the steel socket 11 on the steel cylinder 4. The first steel ring 10 is fixedly connected to the reinforcing rib 13, the first steel ring 10 is in contact with the outer mold 1, and the second steel ring 9 is fixedly arranged coaxially with the first steel ring 10, and the second steel ring 9 is located below the first steel ring 10. The cover body 14 is provided with an observation vent 8, and the cover body 14 is provided with an extraction ring 12, which can facilitate the operator to control the machine to take the cover body 14.

[0024] The device also includes a concrete discharge cone 7 and a vibrator, wherein the concrete discharge cone 7 is connected to the cover body. The vibrator is fixedly connected to the concrete discharge cone 7. When pouring concrete, the vibrator is started, and the vibrator causes the concrete discharge cone 7 to vibrate, and the concrete quickly falls into a designated position under the action of gravity and vibration force. This mechanism can speed up the concrete discharge speed and prevent the concrete from adhering to the concrete discharge cone 7.

[0025] As attached Figure 1 , Figure 2 , Figure 3 As shown:

[0026] The principle of this solution is that the operator first places the base 3, then places the inner mold 5 on the base 3, and locks the inner mold 5, then installs the steel cylinder 4 with the steel socket 11 on the base 3, and then places the outer mold 1 on the base 3 and locks it, and finally installs the top cover 6. The reinforcing ribs 13 of the top cover 6 clamp the outer mold 1 and the steel cylinder 4, the first steel ring 10 and the second steel ring 9 contact the outer mold 1 to stabilize the outer mold 1, the socket 11 can be inserted into the steel cylinder 4 with the steel socket 11, so that the steel cylinder 4 is stable, the cover body 14 clamps the inner mold 5, so that the inner mold 5 is stable, and the top cover 6 clamps the inner mold 5, the steel cylinder 4 with the steel socket 11 and the top of the outer mold 1 in sequence to complete the installation. The operator starts pouring concrete. When pouring concrete, the vibrator starts, which makes the concrete discharge cone 7 vibrate. The concrete quickly falls into the designated position under the action of gravity and vibration force, so that the concrete flows evenly into the gap between the inner mold 5 and the steel cylinder 4, and between the steel cylinder 4 and the outer mold 1, so as to form the concrete pipe core 2.

[0027] After solidification is completed, the concrete feed cone 7 is manually removed, the outer mold 1 is loosened, the top cover 6 is lifted off, the inner mold 5 is loosened, the inner mold 5 is lifted off, the outer mold 1 is lifted off, and the formed steel cylinder 4 concrete pipe is lifted off to complete the construction.

[0028] The beneficial effects of this solution are: 1. This solution stabilizes the top of the outer mold 1 by strengthening the vertical ribs 13, the first steel ring 10 and the second steel ring 9, so that it is not easy to deform during the pouring process, which causes the outer mold 1 to scratch the concrete pipe core 2 when it is taken out. 2. This solution slowly rotates the concrete discharge cone 7 through a vibrator, making the concrete discharge speed more efficient.
