Description

Technical Field

[0001] This utility model relates to the technical field of cement pipe production, and in particular to a cement pipe spigot forming device. Background Technology

[0002] Cement pipes, also known as cement pressure pipes or reinforced concrete pipes, can be used as drainage pipes in urban construction, for sewage discharge, flood control and drainage, as well as water supply pipes in some special factories and mines and farmland wells.

[0003] Existing cement pipe spigot forming devices, such as the one disclosed in utility model patent application number 202321056255.0, mainly include a forming mold, which includes two outer molds and one inner mold. Both the outer and inner molds are placed vertically, forming a pouring zone between them. Vibrators are distributed on the outer wall of the outer mold and the inner wall of the inner mold. In use, the pouring hopper is installed on top of the inner and outer molds, and is limited by a stop block to prevent displacement and deformation during pouring. The effect is good. Then, self-compacting concrete can be poured from above the pouring hopper. The concrete will enter the gap between the inner and outer molds through the pouring hopper, and is vibrated by the vibrators inside the inner mold and outside the outer mold.

[0004] However, existing spigot forming devices are mostly cumbersome to fix the bottom of the mold, which affects the assembly efficiency of the mold. Moreover, during the pouring process, concrete is easily blocked in the pouring port, affecting the pouring effect. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a cement pipe spigot forming device that not only facilitates the fixing and combination of the bottom ends of the two sets of molds, improving the assembly speed of the molds, but also can stir the concrete at the pouring port, causing the concrete to vibrate in the interlayer, facilitating the uniform distribution of concrete in the interlayer, and ensuring the forming effect of cement pipe.

[0006] This utility model discloses a cement pipe spigot forming device, including an internal support mechanism; it also includes two sets of mold mechanisms, a mixing mechanism, and a vibration mechanism. The two sets of mold mechanisms are installed on the internal support mechanism and work together with the internal support mechanism to shape the concrete. The mixing mechanism is installed on the internal support mechanism and mixes the concrete. The vibration mechanism is installed on the mixing mechanism and drives the concrete to vibrate. After the workers assemble the two sets of mold mechanisms, they install them on the internal support mechanism, then pour the concrete into the interlayer, start the mixing mechanism to mix the concrete at the pouring port to prevent the concrete from clogging the pouring port, and at the same time, the vibration mechanism drives the internal support mechanism to vibrate, so as to facilitate the uniform distribution of concrete in the interlayer and ensure the cement pipe forming effect.

[0007] Preferably, the internal support mechanism includes a base, an internal support tube, a connecting plate, and two sets of positioning buckles. The bottom end of the base is connected to the ground, and the bottom end of the internal support tube is connected to the top end of the base. The internal support tube has a cavity. The connecting plate is installed on the base, and both sets of positioning buckles are installed on the connecting plate. The base and internal support tube facilitate the shaping of the cement pipe in conjunction with the mold mechanism. The connecting plate and two sets of positioning buckles facilitate the fixing of the bottom end of the mold mechanism, thereby improving the assembly speed.

[0008] Preferably, the mold mechanism includes an outer mold, two sets of connecting ribs, positioning blocks, a handle, and a vibrator. The outer mold is mounted on a base, and both sets of connecting ribs are mounted on the outer mold with multiple positioning holes. The positioning blocks are mounted on the outer mold, the handle is mounted on the outer mold, and the vibrator is mounted on the outer mold. The operator holds the handle to close the two sets of outer molds, then passes bolts through the positioning holes of the connecting ribs to fix the two sets of mold mechanisms together. Then, the two sets of mold mechanisms are rotated so that the two sets of positioning blocks are engaged in the two sets of positioning buckles, enhancing the connection effect between the two sets of mold mechanisms and the inner support mechanism. A sandwich is formed between the two sets of mold mechanisms and the inner support mechanism, and the vibration of the vibrator causes the concrete in the sandwich to be evenly dispersed.

[0009] Preferably, the outer mold also includes a wear-resistant coating on its inner surface; by spraying a wear-resistant coating on the inner surface of the outer mold, the wear between the concrete and the outer mold is reduced, and the service life of the outer mold is extended.

[0010] Preferably, the mixing mechanism includes a motor, a dual-output-shaft reducer, a first rotating shaft, a dispersing disc, four sets of mixing rods, and an outer casing. The motor is installed in the cavity of the inner support tube, the dual-output-shaft reducer is installed in the cavity of the inner support tube, the first rotating shaft is rotatably mounted on the inner support tube and longitudinally connected to the dual-output-shaft reducer, the bottom end of the dispersing disc is connected to the top end of the first rotating shaft, all four sets of mixing rods are mounted on the dispersing disc, and the outer casing is mounted on the four sets of mixing rods. The worker delivers concrete into the outer casing, and the dispersing disc facilitates the dispersion of the concrete. The motor is started, and the motor drives the first rotating shaft to rotate through the dual-output-shaft reducer. The first rotating shaft drives the dispersing disc and the four sets of mixing rods to rotate, and the four sets of mixing rods mix the concrete, preventing the concrete from clogging at the interlayer feed inlet.

[0011] Preferably, the vibration mechanism includes a second rotating shaft, a turntable, multiple sets of vibrating teeth, and multiple sets of spring plates. The second rotating shaft is mounted on a dual-output shaft reducer, the turntable is mounted on the second rotating shaft, the multiple sets of vibrating teeth are all mounted on the turntable, and the multiple sets of spring plates are all mounted in the cavity of the inner support tube. The dual-output shaft reducer drives the second rotating shaft to rotate, the second rotating shaft drives the turntable and the multiple sets of vibrating teeth to rotate, the multiple sets of vibrating teeth rotate and actuate the multiple sets of spring plates, and the multiple sets of spring plates drive the inner support tube to vibrate, so that the concrete is evenly dispersed.

[0012] Preferably, the vibration teeth are made of 60Si2Mn high-carbon alloy steel. The vibration teeth need to rub against the spring plate for a long time and withstand a large impact force. 60Si2Mn high-carbon alloy steel has high hardness and strong fatigue resistance, making it suitable for high-frequency impact.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: After the workers assemble the two sets of mold mechanisms, they install them on the inner support mechanism, and then pour the concrete into the interlayer. The mixing mechanism is started to mix the concrete at the pouring port to prevent the concrete from blocking the pouring port. At the same time, the vibration mechanism drives the inner support mechanism to vibrate, which facilitates the uniform distribution of concrete in the interlayer and ensures the molding effect of the cement pipe.
