Description

Technical Field

[0001] This invention relates to the field of pipe processing technology, specifically to a pipe demolding device for a pipe top ring. Background Technology

[0002] A pipeline is a device made up of pipes, pipe fittings, and valves used to transport gases, liquids, or fluids containing solid particles. Continuously wound fiberglass reinforced plastic (FRP) sand-filled jacking pipe is a new type of pipeline product that allows for the construction and installation of underground pipelines without excavation. It can directly cross highways, railways, rivers, and surface buildings. This jacking pipe is lightweight, high-strength, and highly corrosion-resistant, offering better mechanical and physical properties compared to traditional reinforced concrete jacking pipes. Existing sand-filled jacking pipes are manufactured using molds. After the jacking pipe is shaped in the mold, demolding is required. However, because the surface of the jacking pipe is tightly attached to the inner wall of the mold, it is difficult to directly separate the jacking pipe from the mold. Therefore, a pipe demolding device is needed to separate the jacking pipe from the mold. Summary of the Invention

[0011] Preferably, the outer diameter of one side of the ring seat is smaller than the inner diameter of the pipe mold, and the outer diameter of the top ring is larger than the inner diameter of the pipe.

[0012] (III) Beneficial Effects

[0013] This invention provides a pipe ejector ring device for pipe demolding. It has the following advantages:

[0014] By setting the ring seat inside the pipe mold and on one side of the pipe, the sliding cylinder is pushed by the hydraulic cylinder, and the top ring pushes one end of the pipe, thus loosening the pipe inside the mold. This makes it easier to remove the pipe from the mold, improving processing efficiency and reducing physical labor consumption. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-5The present invention provides a technical solution: a pipe demolding device for a pipe top ring, including a cylindrical seat 1 and an annular seat 2. The cylindrical seat 1 and the annular seat 2 are coaxially arranged. A connecting arm 3 is fixedly connected between the side of the cylindrical seat 1 and one side of the annular seat 2. Multiple connecting arms 3 are arranged in an equidistant ring on the side of the cylindrical seat 1. In this example, there are six connecting arms 3. The outer diameter of the annular seat 2 is smaller than the inner diameter of the pipe mold. The annular seat 2 is located inside the pipe mold on one side, and the surface of the annular seat 2 is in contact with the inner wall of the pipe mold.

[0023] A sliding cylinder 4 is slidably connected to the inner wall of the cylinder seat 1. A bracket fixing seat 5 is rotatably connected to one end of the sliding cylinder 4. A top ring 6 is provided on one side of the ring seat 2. The outer diameter of the top ring 6 is larger than the inner diameter of the pipe. The top ring 6 is coaxially arranged with the ring seat 2. A top ring bracket 7 is fixedly connected between one side of the top ring 6 and the bracket fixing seat 5. When the ring seat 2 is located inside the pipe mold, the top ring 6 can move to the inside of the pipe mold and contact one end of the pipe. Multiple top ring brackets 7 are provided and are equidistantly distributed in a ring on one side of the bracket fixing seat 5. In this example, there are seven top ring brackets 7. A thrust shaft is provided inside the sliding cylinder 4 and located on one side of the bracket fixing seat 5. The sliding cylinder 4, located away from the support base 5, is fixedly connected to a bearing end cover 9. One side of the bearing end cover 9 extends to the surface of the thrust bearing 8. The bearing end cover 9 and the sliding cylinder 4 are fixed together by a fixing screw. A hydraulic cylinder base is provided on the outer surface of the pipe mold. One end of the hydraulic cylinder base is located on one side of the bearing end cover 9. By moving the hydraulic cylinder, the bearing end cover 9 is pushed, which enables the sliding cylinder 4 to slide inside the cylinder base 1. This can drive the top ring 6 to move, thereby pushing one side of the pipe and separating the pipe from the pipe mold. This facilitates the removal of the pipe from the mold, improves production efficiency, avoids manual demolding, and saves labor.

[0024] The surface of the sliding cylinder 4 is symmetrically provided with guide keys 10, and the inner wall of the cylinder seat 1 is provided with guide grooves 11 that are adapted to the guide keys 10, which ensures that the sliding cylinder 4 does not rotate during movement, and also ensures that it moves along the axial direction of the pipeline under the push of the oil cylinder.
