Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cement pipe production equipment, specifically to a production equipment for reinforced concrete cement pipes. Background Technology
[0002] In the past two years, with the development of municipal engineering and environmental sewage treatment in my country, reinforced concrete pipes have been widely used in factories, mines, oil fields, ports, urban construction and farmland water conservancy projects. Flexible joint steel socket concrete pipes have been gradually promoted and recognized as the best reinforced concrete jacking pipe material in the past decade with the increasing development of urban municipal construction and sewage treatment projects. In the production process of reinforced concrete cement pipes, the mold (or "steel mold") is one of the core equipment in the production equipment of reinforced concrete cement pipes. Its function is to provide a shaped cavity structure for concrete and steel reinforcement skeleton. At present, the mainstream spraying method for the upper mold of the steel mold is to carry out comprehensive spraying through an airless spraying machine (pressure 0.3-0.5MPa) or an electrostatic spraying system. Since the steel mold base mold is initially placed on the ground, it is mostly coated by brushing. By applying the release agent to the surface of the upper mold and the base mold through these methods, the mold will not stick to the reinforced concrete cement pipe. During demolding, the reinforced concrete cement pipe will not be damaged, and the demolding process of reinforced concrete cement pipe can be carried out more conveniently.
[0003] The patent with publication number CN220179669U discloses a production equipment for reinforced concrete cement pipes, including a rotating chassis. The upper surface of the rotating chassis contacts the lower surface of an outer mold, the upper surface of the outer mold contacts the lower surface of a lifting platform, the upper surface of the lifting platform is fixedly connected to the lower surface of a support frame, the surface of the support frame contacts the surface of a second motor, the output end of the second motor is fixedly connected to the upper surface of a connecting shaft, the lower surface of the connecting shaft is fixedly connected to the upper surface of a vibrating core, the surface of the vibrating core is fixedly connected to the surface of an inner mold, the lower surface of the rotating chassis contacts the upper surface of a protective shell, and the inner surface of the protective shell contacts the lower surface of a first motor.
[0004] The above-mentioned device still has the following drawbacks: Although the existing steel mold base mold can be more conveniently painted by brushing, and one can be painted and then another can be painted, the manual painting method is still relatively time-consuming and labor-intensive, which will reduce the work efficiency of workers. Utility Model Content
[0005] In view of the shortcomings of the existing technology, this utility model provides a production equipment for reinforced concrete cement pipes, which can more conveniently apply release agent to the steel mold base mold.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a production equipment for reinforced concrete cement pipes, including a base mold, an installation platform installed at the lower end of the base mold, a support column fixedly connected to the installation platform, a rotating component installed on the support column, a release agent storage box fixedly connected to the rotating component, a transmission pipe connected to the internal space fixedly connected to the side wall of the release agent storage box, an outer shell sleeve installed at the end of the transmission pipe, and two identical liquid outlet grooves opened on the inner wall of the outer shell sleeve.
[0007] Furthermore, the outer casing is configured with a double-disc structure, and there is a cavity inside the outer casing. The two liquid outlet grooves are located on the two horizontal disc surfaces of the outer casing and are connected to the cavity inside them. The double-disc structure of the outer casing is adapted to the size and shape of the double-disc structure of the base mold.
[0008] Furthermore, the rotating component is a rotating rod, and a cylindrical groove is provided through the upper end of the support column. The rotating rod is rotatably and slidably connected in the cylindrical groove, and the top end of the rotating rod is fixedly connected to the lower surface of the release agent storage box.
[0009] Furthermore, a release agent transmission power pump is installed on the upper surface of the release agent storage box. A first fastening bolt is threaded onto the release agent transmission power pump. The first fastening bolt passes through the release agent transmission power pump and extends into the outer wall of the release agent storage box for bolt fastening.
[0010] Furthermore, a second disc-shaped groove is formed at the center of the top of the outer casing, and a first disc-shaped groove is formed below the second disc-shaped groove at the center of the top of the outer casing, which is connected to the second disc-shaped groove. The first disc-shaped groove is also connected to the internal cavity of the outer casing. A rotating disk is rotatably connected in the first disc-shaped groove. The upper end of the rotating disk is fixedly connected to the lower end of the transmission pipe, and the opening of the transmission pipe passes through the lower end of the rotating disk and is connected to the internal cavity of the outer casing. The outer wall of the transmission pipe is rotatably and slidably connected to the outer wall of the second disc-shaped groove.
[0011] Furthermore, a valve is installed on the lower outer wall of the transmission pipe.
[0012] Furthermore, a sponge sleeve that is perfectly matched to the shape and size of the outer shell is installed on the inner wall of the outer shell. The top of the outer shell is connected to two symmetrically arranged second fastening bolts on the outer side of the second disc-shaped groove. Both second fastening bolts penetrate the outer shell into the sponge sleeve for bolt fastening. The two second fastening bolts are also located on the outer side of the liquid outlet groove on the upper outer shell.
[0013] Furthermore, a handle is fixed to the outer wall of the lower disc of the outer casing, and an anti-slip pad is installed on the outer wall of the handle.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] This utility model utilizes the cooperation of a release agent storage box, a release agent transmission power pump, an outer shell, and a sponge sleeve to achieve all-round coverage of the base mold. Then, the release agent is delivered to the sponge sleeve by the release agent transmission power pump, allowing the sponge sleeve to saturate the surface of the base mold and complete the application of the release agent. This is more convenient, with a simple structure, easy operation, and strong practicality.
[0016] This invention utilizes the cooperation between a rotating disc and a handle. When the user pushes the handle, it can drive the outer shell and the inner sponge sleeve to swing and rotate flexibly left and right around the center axis. This design allows the sponge sleeve to continuously wipe the surface of the base mold during operation, thereby improving the uniformity and coverage of the release agent application and achieving a higher standard of mold surface treatment quality.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] like Figures 1 to 8 As shown, a production equipment for reinforced concrete cement pipes includes a base mold 1, an installation platform 2 installed at the lower end of the base mold 1, a support column 3 fixedly connected to the installation platform 2, a rotating component installed on the support column 3, a release agent storage box 6 fixedly connected to the rotating component, a transmission pipe 9 connected to the internal space fixedly connected to the side wall of the release agent storage box 6, an outer shell 11 installed at the end of the transmission pipe 9, and two liquid outlet grooves 17 of the same size opened on the inner wall of the outer shell 11.
[0028] like Figure 1 As shown, the production equipment for reinforced concrete cement pipes in this utility model is structurally similar to existing reinforced concrete cement pipe production equipment. For example, patent publication number CN220179669U discloses a production equipment for reinforced concrete cement pipes. The main improvement of this utility model is that it allows for more convenient application of release agent to the steel mold base mold. Figures 1 to 8 As shown, when using the production equipment for reinforced concrete cement pipes of this utility model, the rotating component is first moved upward, and then the base mold 1 is placed on the mounting platform 2. Next, the rotating component is moved downward, causing the release agent storage box 6, the transmission pipe 9, and the outer shell 11 to move downward together, so that the outer shell 11 covers the base mold 1. Then the release agent can be added, and under the transport of the transmission pipe 9, it reaches the base mold 1 through the liquid outlet 17. Subsequently, during the coating process, the outer shell 11 is rotated to coat the release agent.
[0029] It is worth noting that the base mold 1 is placed at the center of the upper surface of the mounting platform 2.
[0030] like Figure 2 , Figure 3 and Figure 6 As shown, the outer casing 11 has a double-disc structure. There is a cavity inside the outer casing 11. Two liquid outlet grooves 17 are located on the two horizontal disc surfaces of the outer casing 11 and are connected to the cavity inside. The double-disc structure of the outer casing 11 is compatible with the size and shape of the double-disc structure of the base mold 1, so that it can cover the entire base mold 1 and reduce the omissions.
[0031] It is worth noting that the inner diameter of the outer casing 11 is 1-2 mm larger than the outer diameter of the base mold 1, which can improve the covering effect.
[0032] like Figure 3 and Figure 5 As shown, the rotating component is a rotating rod 5. A cylindrical groove 4 is provided through the upper end of the support column 3. The rotating rod 5 is rotatably and slidably connected in the cylindrical groove 4. The top end of the rotating rod 5 is fixedly connected to the lower surface of the release agent storage box 6.
[0033] Specifically, by moving the rotating rod 5 upward, the outer casing 11 can be lifted and placed into the base mold 1. Then, by moving the rotating rod 5 downward, the outer casing 11 can be put onto the base mold 1, which allows for convenient replacement of the base mold 1. If it is necessary to clean the surface of the mounting platform 2, the rotating rod 5 can be rotated to turn the outer casing 11 to the other side, and the user can then clean the surface of the mounting platform 2.
[0034] like Figure 2 , Figure 3 and Figure 4 As shown, a release agent transmission power pump 7 is installed on the upper surface of the release agent storage box 6. A first fastening bolt 8 is threaded onto the release agent transmission power pump 7. The first fastening bolt 8 passes through the release agent transmission power pump 7 and extends into the outer wall of the release agent storage box 6 for bolt fastening.
[0035] Specifically, although the release agent can be poured into the box and then flow into the outer casing 11 under gravity, this is still not very convenient, and the utilization rate of the release agent is not high. By using the release agent transmission power pump 7 to push the release agent in the box into the transmission pipe 9 and then into the outer casing 11, the utilization rate of the release agent can be improved. Moreover, the release agent transmission power pump 7 can be turned on when needed and turned off when not needed. Finally, it can also be disassembled by the first fastening bolt 8, and the user can also regularly inspect or maintain the release agent transmission power pump 7.
[0036] like Figure 3 , Figure 7 and Figure 8 As shown, a second disc-shaped groove 13 is provided at the center of the top of the outer casing 11. A first disc-shaped groove 12, which is connected to the second disc-shaped groove 13, is provided below the center of the top of the outer casing 11. The first disc-shaped groove 12 is also connected to the internal cavity of the outer casing 11. A rotating disk 14 is rotatably connected inside the first disc-shaped groove 12. The upper end of the rotating disk 14 is fixedly connected to the lower end of the transmission pipe 9, and the opening of the transmission pipe 9 passes through the lower end of the rotating disk 14 and is connected to the internal cavity of the outer casing 11. The outer wall of the transmission pipe 9 is located on the outer wall of the second disc-shaped groove 13 and is rotatably and slidably connected.
[0037] Specifically, by rotating the outer casing 11, the outer casing 11 is rotated around the end of the rotating disk 14 and the transmission pipe 9, and the surface of the base mold 1 that needs to be coated with the release agent is wiped and brushed.
[0038] It is worth noting that during operation, the rotating disk 14 itself does not rotate. The outer casing 11 can rotate around the transmission tube 9 only through the rotating disk 14. Moreover, the outer casing 11 will not detach from the transmission tube 9 due to the obstruction of the rotating disk 14.
[0039] like Figure 2 , Figure 3 and Figure 7 As shown, a valve 10 is installed on the lower outer wall of the transmission pipe 9.
[0040] Specifically, when it is necessary to shut down the release agent transmission power pump 7, although the release agent transmission power pump 7 can be shut down to stop it from working and pushing the release agent forward, in order to prevent the residual liquid from continuing to move forward and entering the cavity of the outer casing 11, the valve 10 is closed and the transmission pipe 9 is closed, and then the liquid can no longer enter the cavity of the outer casing 11.
[0041] like Figure 2 and Figure 3 As shown, a sponge sleeve 15 that is perfectly matched in shape and size to the outer shell sleeve 11 is installed on the inner wall of the outer shell sleeve 11. The top of the outer shell sleeve 11 is connected to two symmetrically arranged second fastening bolts 16 on the outer side of the second disc groove 13. Both second fastening bolts 16 penetrate the outer shell sleeve 11 into the sponge sleeve 15 for bolt fastening. The two second fastening bolts 16 are also located on the outer side of the liquid outlet groove 17 on the upper outer shell sleeve 11.
[0042] Specifically, the release agent is pushed into the outer casing 11 by the release agent transmission power pump 7, and then enters the sponge sleeve 15 through the liquid outlet 17, soaking and filling the sponge sleeve 15 with the release agent. Then, by rotating the outer casing 11, the sponge sleeve 15 filled with release agent can continuously wipe all the surfaces of the base mold 1 that need to be coated. This is not only quick and convenient, but also reduces the impact of hard materials on the base mold 1, preventing damage to the base mold 1, reducing brush marks, extending service life, improving the quality of the cement pipe after production, saving materials, and adapting to complex surfaces. Finally, the sponge sleeve 15 is fixed to the outer casing 11 by the second fastening bolt 16, making it detachable and allowing for regular maintenance and replacement.
[0043] It is worth noting that the release agent in the release agent storage box 6 is pressurized by the release agent transmission power pump 7, and then transported to the cavity of the outer shell sleeve 11 through the transmission pipe 9. It flows out through the liquid outlet 17 and penetrates into the sponge sleeve 15, eventually wetting the surface of the base mold 1.
[0044] In addition, the sponge sleeve 15 is made of polyurethane open-cell sponge (pore size 0.5-1mm, liquid absorption rate ≥80%), which is compatible with water-based release agents with a viscosity of 20-50mPa·s.
[0045] like Figure 2, Figure 3 and Figure 8 As shown, a handle 18 is fixed to the outer wall of the lower disc of the outer casing 11, and an anti-slip pad is installed on the outer wall of the handle 18.
[0046] Specifically, the handle 18 makes it easier and more convenient for users to rotate or move the outer shell 11 and the sponge cover 15 up and down, while the anti-slip pad reduces the chance of the hand slipping off.
[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
