Description

Technical Field

[0001] This utility model belongs to the technical field of casting molds for tubular buildings, and specifically relates to a precast concrete tubular casting system. Background Technology

[0002] Pipe houses are a new type of living space created by converting concrete pipe structures. They incorporate space capsule design concepts, emphasizing rapid installation and mobility. Compared to traditional housing structures, they are less expensive and have a unique style. Existing pipe houses are typically reinforced concrete structures, requiring the use of casting molds during the pouring process.

[0003] Centrifugal casting is commonly used in the existing concrete pipe casting process. A rotating mechanism drives the mold to rotate, and then concrete is poured into the mold (a steel cage is installed inside the mold). The centrifugal force of the rotating mold will spread the concrete evenly on the inner wall of the mold. After multiple batches of pouring and water replenishment, the inner wall of the concrete pipe is leveled, and then the mold and the concrete pipe as a whole can be moved out of the rotating mechanism to the curing area. When leveling the inner wall of the concrete pipe, workers sometimes use hand-held leveling tools (often iron rods, etc.) to scrape the inner wall of the concrete pipe. At this time, the rotating mechanism is in operation. The relative movement between the rotating inner wall of the concrete pipe and the iron rod completes the removal of burrs.

[0004] The process of workers scraping the inner wall of poured concrete pipes with shaving tools is physically demanding (workers must overcome the impact of burrs on the shaving tools and maintain their relative stability). Furthermore, worker errors can easily cause damage to both the worker and the inner wall of the concrete pipe. Additionally, workers need to get extremely close to the middle section of the concrete pipe's inner wall, and the high-speed rotation of the pipe poses a significant safety hazard. In summary, the existing mold structure is labor-intensive and poses significant safety risks during deburring. Utility Model Content

[0005] The present invention aims to provide a precast concrete pipe casting system to solve the problem of significant safety hazards in the use of existing mold structures mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precast concrete pipe casting system, comprising a mold body and a rotating mechanism, wherein the rotating mechanism is mounted on a base surface, and the mold body is mounted on the rotating mechanism, including...

[0007] The leveling unit includes uprights, diagonal braces, cross braces, mounting blocks, and guide components. The uprights are mounted on the mounting blocks. One end of the diagonal brace is fixed to the top of the upright, and the other end of the diagonal brace is equipped with a scraper. Both ends of the cross brace are fixed to the uprights and the diagonal brace, respectively. The mounting blocks are movable on the base surface. The guide components are used to restrict the axial movement of the mounting blocks along the mold body.

[0008] The principle and effect of this technical solution: By installing the scraper on a frame composed of uprights, diagonal braces, and crossbars, and installing the uprights through mounting blocks, workers do not need to directly hold the leveling tools, and the resistance during deburring is not directly transmitted to the workers, reducing their workload. At the same time, the guide components ensure the accuracy of the leveling unit's movement, preventing damage to the inner wall of the concrete pipe caused by misalignment. Furthermore, when controlling the scraper's movement into the concrete pipe, workers only need to control the position of the mounting blocks, eliminating the need for uprights and also isolating the mold body from the workers, thus enhancing safety.

[0009] The present invention is further configured to include a positioning block and a guide plate. The positioning block is fixed on the base surface, the guide plate is slidably inserted into the positioning block and abuts against the base surface, one end of the guide plate is detachably connected to the mounting block, and a roller is fixed on the side wall of the mounting block and abuts against the base surface.

[0010] The principle and effect of this technical solution: By sliding the guide plate and the positioning block, the mounting block can only move along the length of the guide plate after being connected to the guide plate. This makes the movement path of the leveling unit body relative to the mold body stable and reliable. The rollers facilitate the movement of the mounting block. At the same time, the connection between the guide plate and the mounting block can distribute the force in the direction other than the length of the guide plate, thereby stabilizing the position of the mounting block. That is, the guide plate overcomes the resistance encountered during deburring. The detachable design allows the device to be moved away from the mold body when deburring and leveling are not required, thus giving way. It can also be moved to the other side to level the mold body without the need to prepare more leveling units.

[0011] The present invention is further configured such that positioning blocks and guide plates are provided on both sides of the mold body.

[0012] The principle and effect of this technical solution: By setting positioning blocks and guide plates on both sides, the mounting blocks can work on both sides of the mold body by detaching and attaching with the guide plates. This reduces the required length of the uprights, diagonal bars and crossbars, thereby reducing the torque force that the leveling unit needs to withstand during leveling to a certain extent. This makes the leveling unit more stable and reliable in use and extends its service life.

[0013] The present invention is further configured such that the ratio of the length of the guide plate to the axial length of the mold body is greater than 0.5 and less than 1.

[0014] The principle and effect of this technical solution: By limiting the length of the guide plate, the scraper can be limited and guided by the guide plate before entering the mold body.

[0015] The present invention is further configured such that: a movable groove is provided on the outer wall of the mounting block, a mounting cylinder is rotatably fitted in the movable groove, a limit bolt is inserted into the side wall of the mounting block, the end of the limit bolt can be threaded into the mounting cylinder, and the upright is installed on the outer wall of the mounting cylinder.

[0016] The principle and effect of this technical solution: By setting up the movable groove and the mounting cylinder, the position of the upright relative to the mounting block can be changed by rotation after the upright is installed on the mounting cylinder. That is, when not in use, the upright can be rotated to abut against the base surface, so that the leveling unit does not need to be too far away from the mold body. At the same time, it can reduce the occupation of vertical space, so as to avoid the presence of uprights, diagonal braces, etc. interfering with the concrete pipes after pouring and the overall movement of the mold body. Furthermore, by setting up the limiting bolt, the limiting bolt can connect the mounting block and the mounting cylinder into a whole, and the limitation of the limiting bolt on the mounting cylinder can also be released by rotation.

[0017] The present invention is further configured such that: an extension cylinder is installed on the mounting block, a nut sleeve is rotatably installed on the top of the extension cylinder, an anti-rotation block is fixed at the bottom of the upright, the anti-rotation block slides with the extension cylinder, and the upright is threaded into the nut sleeve.

[0018] The principle and effect of this technical solution: By sliding the anti-rotation block and the extension cylinder, the upright can only slide and cannot rotate relative to the extension cylinder. Furthermore, by setting the nut sleeve and the threaded engagement of the upright, the height of the upright can be controlled by rotating the nut sleeve. Thus, the height of the scraper relative to the inner wall of the mold body can be adjusted by controlling the height of the upright, making it more flexible to use.

[0019] The present invention is further configured such that the cross-section of the anti-rotation block is square.

[0020] The principle and effect of this technical solution: The square shape makes the anti-rotation block and the extension cylinder have an anti-rotation effect, while the anti-rotation block is easy to process and form and the fit is stable. Attached Figure Description
