Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The purpose of this invention is to provide a horizontal, base-mounted, flexible-interface, double-rubber-ring reinforced concrete pipe production device to solve the problems existing in the prior art. It has a simple structure, is easy to use, effectively solves the problem of inner mold demolding in horizontal production processes, and effectively improves the quality of inner wall forming.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] This embodiment provides a horizontal, base-mounted, flexible-joint, double-rubber-ring reinforced concrete pipe production device, such as... Figures 1-3 As shown, the system includes: a base 1, an outer mold 2, an inner mold 3, a jacking mechanism 4, and a traction mechanism 5. The base 1 is installed on the working ground. The outer mold 2 is a half-mold and is installed on the base 1. The inner mold 3 is a seamless hollow cylinder, which is installed inside the outer mold to form a casting space for the double-rubber-ring reinforced concrete pipe 6 between the outer mold 2 and the inner mold 3. One end of the inner mold 3 is provided with a jacking part 31, and the other end is provided with a traction part 32. The jacking mechanism 4 is located on one side of the base 1. When the strength of the double-rubber-ring reinforced concrete pipe 6 reaches 70%~75% of the design strength, the jacking mechanism 4 jacks the jacking part 31 to form an initial separation gap between the inner mold 3 and the double-rubber-ring reinforced concrete pipe 6. The traction mechanism 5 is located on the side of the base 1 away from the jacking mechanism 4. The traction mechanism 5 is used to work with the traction mechanism 5. The lead-out part 32 is connected to pull out the inner mold 3 horizontally. The base 1 is used to install on the working ground, providing a stable support platform for the entire production device, ensuring that the device will not shake or shift during operation, thus guaranteeing the stability and reliability of production. The outer mold 2 is installed on the base 1 using a half mold. The inner mold 3 is a seamless hollow cylinder and is installed inside the outer mold 2 to form a casting space. This structure can precisely control the size and shape of the double rubber ring reinforced concrete pipe 6, which is beneficial to improving the precision and quality of the product. The inner mold 3 is equipped with a jacking part 31 and a traction part 32. The jacking mechanism 4 and the traction mechanism 5 are located on both sides of the base 1 and work together. By operating at the appropriate pipe strength stage, it is easy to achieve smooth demolding of the inner mold 3, reducing damage to the pipe and ensuring the integrity and quality of the product.

[0028] In a preferred embodiment, one end of the outer mold 2 is provided with a tapered socket forming section, and the other end is provided with a spigot forming section whose taper matches that of the socket forming section. The spigot forming section is provided with double rubber ring protrusions. The top of the outer mold 2 is provided with a concrete pouring port. The design of the tapered socket forming section and the matching spigot forming section ensures that the produced double rubber ring reinforced concrete pipe 6 can achieve a tight fit during installation. In addition, the double rubber ring protrusions of the spigot forming section further enhance the sealing performance at the joint, effectively preventing leakage during pipe use. The concrete pouring port at the top of the outer mold 2 facilitates the pouring of concrete into the pouring space during the production process, optimizes the concrete pouring operation process, improves production efficiency, and helps ensure uniform distribution of concrete in the pouring space, thereby improving product quality.

[0029] In a preferred embodiment, the outer mold 2 includes an outer mold body 21, a spigot plate 22, and a socket plate 23. The outer mold body 21 is fitted onto the outside of the inner mold 3. The spigot plate 22 is installed at one end of the outer mold body 21 to close one end of the casting space. The spigot plate 22 is provided with a spigot forming plate that extends into the outer mold body 21 and is close to the inner wall of the outer mold body 21. Double rubber rings protrude from the side of the spigot forming plate away from the outer mold body 21. The socket plate 23 is installed at the other end of the outer mold body 21 to close the other end of the casting space. The socket plate 23 is provided with a socket forming plate that extends into the outer mold body 21 and is close to the inner wall of the outer mold body 21. The outer mold 2 adopts the outer mold body. 21. The structure of the spigot plate 22 and the socket plate 23 can accurately seal both ends of the pouring space, ensuring that the concrete will not overflow during the pouring process. At the same time, it precisely constrains the shape and size of the pouring space, which is conducive to producing double-rubber ring reinforced concrete pipes 6 with high dimensional accuracy and standardized shape. The setting of the spigot forming plate and the layout of the double rubber ring protrusion on the side away from the outer mold body 21 make the produced double rubber ring protrusions accurate in position and regular in shape, which helps to achieve a good sealing effect when connecting pipes. The socket forming plate extends into the outer mold body 21 and is set close to the inner wall, ensuring the forming quality of the socket and enabling the size and shape of the socket to be precisely matched with the spigot, thereby improving the stability and sealing of the pipe connection.

[0030] In a preferred embodiment, the outer surface of the inner mold 3 is mirror-finished to a roughness Ra≤0.8μm, resulting in a mirror-like smooth inner wall of the formed pipe. This smooth inner wall significantly reduces fluid resistance during flow within the pipe, effectively improving transport efficiency and reducing energy consumption for pipelines transporting various liquids. For example, in sewage and drainage pipes, water flows more smoothly, reducing the possibility of water stagnation and dirt adhesion, thereby extending the pipe's service life.

[0031] In a preferred embodiment of this invention, the inner mold may also be a radially openable petal-shaped structure, the opening and closing action of which is controlled by a hydraulic drive mechanism, and the radial opening and closing gap control accuracy of the hydraulic drive mechanism is ≤0.02mm.

[0032] In a preferred embodiment, the jacking mechanism 4 includes a first limiting baffle 41 and a jack 42. The first limiting baffle 41 is fixedly connected to one side of the base 1, and the jack 42 is horizontally installed on the side of the first limiting baffle 41 facing the base 1. The jack head of the jack 42 is used to tighten the jacking part 31. The first limiting baffle 41, fixed to one side of the base 1, provides accurate positioning for the jack 42, ensuring that the jack 42 is horizontally installed and can stably act on the jacking part 31. The horizontal installation of the jack 42 and the design of the jack head tightening the jacking part 31 enable the jacking process to proceed smoothly and accurately form an initial separation gap between the inner mold 3 and the double-rubber-ring reinforced concrete pipe 6, avoiding damage to the pipe body due to unstable jacking.

[0033] In a preferred embodiment, the ejector part 31 is a hemispherical groove, and the ejector head is a hemispherical protrusion 421 that matches the ejector part 31. The matching design of the hemispherical groove and the hemispherical protrusion 421 not only increases the contact area between the two during ejection and improves the stability of the ejection, but also better adapts to the structural characteristics of the inner mold 3, ensures the uniform transmission of force during ejection, reduces the risk of damage to the tube body and the inner mold 3 caused by local stress concentration, and improves the reliability and stability of demolding.

[0034] In a preferred embodiment, the traction mechanism 5 includes a support 51, a winch 52, a wire rope 53, a pulley 54, and a traction rope 55. The traction part 32 is a hook. The support 51 is located on the side of the base 1 away from the first limiting baffle 41. The winch 52 is mounted on the support 51 and is connected to the pulley 54 via the wire rope 53. The pulley 54 is connected to the hook via the traction rope 55. The support 51 provides stable support, and the winch 52 serves as a power source. Through the transmission connection of the wire rope 53, pulley 54, and traction rope 55, the inner mold 3 can be pulled horizontally out of the tube body smoothly and efficiently. This transmission structure design makes the traction process highly controllable, ensuring that the speed of the inner mold 3 is uniform when it is pulled out, avoiding damage to the tube body and the inner mold 3 due to sudden speed changes, ensuring smooth demolding of the inner mold 3, and improving the success rate of production and product quality.

[0035] In a preferred embodiment, the traction mechanism 5 further includes a second limiting baffle 56. The second limiting baffle 56 is provided with a guide through hole 561 matching the inner mold 3. The second limiting baffle 56 is fixedly connected to the side of the base 1 away from the first limiting baffle 41. The guide through hole 561 is used to allow the inner mold 3 to pass horizontally and restrict the movement of the double rubber ring reinforced concrete pipe 6 towards the winch 52. Restricting the movement of the double rubber ring reinforced concrete pipe 6 towards the winch 52 helps to maintain the stable position of the pipe body during the demolding process, avoids the pipe body from shifting or deforming due to external traction, and ensures the geometric dimensions and shape accuracy of the product.

[0036] In a preferred embodiment, the system further includes a sliding bracket 57. The sliding bracket 57 is positioned on the working surface away from the first limiting baffle 41 by a second limiting baffle 56 to receive the inner mold 3 passing through the guide hole 561. The sliding bracket 57 provides good support for the inner mold 3 when it passes through the guide hole 561, preventing damage caused by direct contact with the ground after demolding. Simultaneously, it provides a fixed placement position for the inner mold 3, facilitating its orderly storage and subsequent maintenance, increasing its service life, and reducing production costs.

[0037] In a preferred embodiment, the traction direction of the winch 52 is consistent with the axial direction of the double-rubber-ring reinforced concrete pipe 6. This ensures that the inner mold 3 is subjected to uniform force in all directions during the process of being pulled away from the pipe body, preventing twisting or skewing. This guarantees that the inner mold 3 can be smoothly and easily removed from the pipe body, effectively protecting the integrity of the inner mold 3 and the pipe body, and improving product quality and production efficiency.

[0038] In a preferred embodiment, the inner mold 3 can also be a radially openable petal-shaped structure with a radial opening and closing gap control accuracy ≤0.02mm. Its opening and closing action is controlled by a traction mechanism and an ejector mechanism. When the traction mechanism 5 and the ejector mechanism 4 move the inner mold towards the traction mechanism, the inner mold can contract radially. The inner mold's radially openable petal-shaped structure and the control of its opening and closing action by the traction and ejector mechanisms, with a radial opening and closing gap control accuracy ≤0.02mm, ensure the accuracy of the inner mold 3's radial contraction. During demolding, the inner mold can be accurately reduced in size and separated from the inner wall of the pipe, avoiding frictional damage between the inner mold and the pipe. Precise control can be guaranteed in both small and large diameter pipe production, thereby improving product yield and mold lifespan. When the traction mechanism and the ejector mechanism move the inner mold towards the traction mechanism, the inner mold can contract radially. This collaborative working method makes the demolding process smoother and more efficient. The coordinated action of the two mechanisms can achieve the radial shrinkage of the inner mold 3 while the inner mold is detached from the tube body, reducing the time and operation steps required for demolding, improving the overall production efficiency, and helping to achieve continuous and rapid production operations.

[0039] The following are the usage instructions for the above-mentioned horizontal, base-mounted, flexible joint, double-rubber-ring reinforced concrete pipe production device:

[0040] Preparation stage of production equipment

[0041] Site and equipment installation

[0042] Install the base 1 on a stable and solid working surface to ensure that the base 1 is firmly fixed and will not shake or shift during the production process, thus providing a stable and reliable support platform for the entire production unit.

[0043] Install the lower half of the outer mold 2 (using a half mold) onto the base 1. If reinforcement is required in the double-rubber ring reinforced concrete pipe 6, tie the reinforcement. Then place a pad or support block that matches the spacing between the inner mold 3 and the outer mold 2. If reinforcement is not required, place a pad or support block that matches the spacing between the inner mold 3 and the outer mold 2 directly. Then place the inner mold 3. Then install the upper half of the outer mold 2. The spigot plate 22 and the socket plate 23 are installed at both ends of the pipe body to ensure that the pouring space is accurately sealed and the position of the double rubber ring protrusion is precise.

[0044] A double-rubber ring reinforced concrete pipe 6 is formed between the inner mold 3 and the outer mold 2 of the seamless hollow cylinder. During installation, attention should be paid to the position and posture of the inner mold 3 to ensure that the gap between it and the outer mold 2 is uniform, so as to facilitate the subsequent forming accuracy of the concrete pipe.

[0045] Inspection and maintenance

[0046] Inspect the jacking mechanism 4 and the traction mechanism 5 to ensure that the first limit baffle 41 and the second limit baffle 56 are firmly fixed. The jack 42 is horizontally installed on the side of the first limit baffle 41 facing the base 1, and the jack head and the jacking part 31 can be well matched. The winch 52 is installed on the support 51. The transmission connection between the wire rope 53, pulley 54 and traction rope 55 is normal and without wear. There is no damage or looseness of the parts of each mechanism.

[0047] Confirm that the ejector part 31 of the inner mold 3 is a hemispherical groove and the ejector head is a matching hemispherical protrusion 421; the traction part 32 is a hook and is undamaged; check the dimensional accuracy of the guide through hole 561 on the second limit baffle 56 that matches the inner mold 3 to ensure that the inner mold 3 can pass smoothly horizontally, and at the same time confirm that the sliding bracket 57 is installed in the appropriate position, ready to receive the inner mold 3 after demolding.

[0048] The casting and forming stage of reinforced concrete pipes

[0049] Concrete pouring

[0050] High-performance mixed concrete is poured into the pouring space formed by the outer mold 2 and the inner mold 3 through the concrete pouring port set at the top of the outer mold 2. During this process, it is necessary to ensure that the concrete fills the pouring space evenly, avoid local concrete accumulation or missing parts, and ensure the integrity and density of the concrete in the pipe body.

[0051] Post-pouring curing

[0052] After pouring, the double-ring reinforced concrete pipe 6 is statically cured in a suitable environment according to the curing requirements of high-performance concrete. The curing time and environmental conditions need to be determined based on the concrete formula and actual conditions, with the aim of ensuring that the pipe reaches a certain design strength before proceeding to the demolding process.

[0053] Demolding stage of inner mold 3

[0054] jacking mechanism 4 operation

[0055] When the strength of the double-rubber-ring reinforced concrete pipe 6 reaches 70% of its design strength, the jacking mechanism 4 is activated. Under the positioning action of the first limit baffle 41, the jack 42 horizontally presses against the jacking part 31 (hemispherical groove) of the inner mold 3. The jack 42 is operated slowly to jack up the pipe, creating an initial separation gap between the inner mold 3 and the double-rubber-ring reinforced concrete pipe 6. During the jacking process, stable operation must be ensured to avoid damage to the pipe body and inner mold 3 due to excessive jacking speed or uneven force.

[0056] Traction mechanism 5 operation

[0057] After the jacking mechanism 4 completes the initial jacking, the pulley 54 of the traction mechanism 5 is connected to the hook of the traction part 32 of the inner mold 3 via the traction rope 55. The winch 52 is started, and the winch 52 is connected to the pulley 54 via the wire rope 53, smoothly and at a uniform speed pulling the entire inner mold 3 horizontally away from the pipe body. Since the traction direction of the winch 52 is consistent with the axial direction of the double rubber ring reinforced concrete pipe 6, the inner mold 3 is subjected to uniform force in all directions during the traction process, and can be smoothly released.

[0058] During this process, the second limiting baffle 56 and its guide through hole 561 function to provide precise guidance for the horizontal movement of the inner mold 3, restricting the movement of the double-rubber-ring reinforced concrete pipe 6 towards the winch 52, ensuring that the inner mold 3 can be smoothly disengaged and that the pipe body is in a stable position. At the same time, the movement of the inner mold 3 is closely monitored to ensure that it is pulled out of the guide through hole 561 continuously and smoothly.

[0059] Inner mold 3 storage

[0060] After the inner mold 3 is horizontally pulled out of the tube and passes through the guide hole 561, it enters the sliding bracket 57. The sliding bracket 57 provides good support for the inner mold 3 after demolding, prevents the inner mold 3 from directly contacting the ground and causing damage, and facilitates the orderly storage and subsequent maintenance of the inner mold 3.

[0061] Post-production sorting and reuse stage

[0062] Cleaning and maintenance of production equipment

[0063] After production is completed, the production equipment should be cleaned in a timely manner, removing any residual concrete and other impurities from the surfaces of components such as outer mold 2 and inner mold 3. All components should be lubricated and maintained, and any wear should be checked.

[0064] Pay special attention to the wear and tear and connection condition of the components of the jacking mechanism 4 and the traction mechanism 5, and promptly repair or replace any problems that arise to ensure that the equipment is in good operating condition for the next use.

[0065] Mold readjustment and use

[0066] According to subsequent production needs, if it is necessary to produce double-rubber ring reinforced concrete pipes 6 of different specifications and sizes, the installation positions of the outer mold 2 and inner mold 3 should be adjusted accordingly or suitable outer mold 2 and inner mold 3 should be replaced. At the same time, ensure that the fitting accuracy of each related component meets the production process requirements so as to smoothly carry out the next production operation and realize the adaptability of the production equipment to different specifications of products and multiple uses.

[0067] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
