A side-end plate pull-out tube segment production mold

Abstract

This invention relates to the field of tunnel segment production mold technology, and discloses a side-end plate pull-out tunnel segment production mold, including a base, a support block fixedly connected to the top of the base, a tunnel segment mold fixedly connected to the top of the support block, a pull-out demolding mechanism provided on the side wall of the tunnel segment mold, a plurality of mixing mechanisms provided on the top of the base, and a plurality of telescopic moving mechanisms provided on the bottom of the base. This invention, by setting up a pull-out demolding mechanism, uses a first vibration motor to drive a vibrating plate to vibrate, which in turn drives the moving side plate to vibrate, separating the internally formed concrete tunnel segment from the tunnel segment mold. A first hydraulic cylinder then extends, causing a connecting block to slide within a limiting groove and the moving side plate to slide within a fitting groove, moving it out from one side of the tunnel segment mold, thus removing the formed tunnel segment from the mold. This achieves effective and rapid demolding of the tunnel segment adhered to the inner wall of the tunnel segment mold, effectively avoiding damage to the tunnel segment caused by violent demolding.

Description

Technical Field

[0001] This invention belongs to the field of tube segment production mold technology, and more specifically, relates to a side end plate pull-out tube segment production mold. Background Technology

[0002] Segment construction is the main assembly component of shield tunneling. It is the innermost barrier of the tunnel and bears the responsibility of resisting soil pressure, groundwater pressure and some special loads. Segment construction is the permanent lining structure of shield tunnels. The quality of segment construction is directly related to the overall quality and safety of the tunnel, and affects the tunnel's waterproof performance and durability. The production of segment construction requires the use of segment molds, which are special concrete precast molds made of mold steel and consisting of a base plate, four side plates and two top covers for the production of tunnel segments. However, when using existing segment production molds, the concrete segments tend to stick to the surface of the mold after molding and become embedded inside the mold as a whole. This makes it difficult to quickly and effectively demold the molded segments. The use of forceful demolding methods can easily damage the segments, making them inconvenient to use. Summary of the Invention

[0003] The purpose of this invention is to provide a side-end plate pull-out tube sheet production mold, which has the advantage of effectively and conveniently removing the tube sheets that are stuck together after molding, without the need for violent demolding and thus avoiding damage to the tube sheets.

The pull-out demolding mechanism includes several first hydraulic cylinders, several connecting blocks, a movable side plate, a first vibration motor, a vibration plate, a mating groove, and several limiting slide grooves. Several first hydraulic cylinders are fixedly connected to the side wall of the segment mold. One end of several connecting blocks is fixedly connected to the output end of the first hydraulic cylinder. The side wall of the movable side plate is fixedly connected to the other end of the connecting block. The first vibration motor is fixedly installed on the inner side of the bottom end of the movable side plate. The bottom end of the vibration plate is fixedly connected to the output end of the first vibration motor. The mating groove is opened in the inner wall of the segment mold, and several limiting slide grooves are opened in the side wall of the segment mold.

[0005] Optionally, the mixing mechanism includes a support column, a motor, a rotating connecting rod, a top cover, an electric push rod, a fixed frame, a second vibration motor, a vibrating rod, and a limiting slot. The bottom end of the support column is fixedly connected to the top end of the base. The motor is fixedly installed on the side wall of the support column. One end of the rotating connecting rod is rotatably connected to the top end of the support column. One end of the top cover is fixedly connected to the other end of the rotating connecting rod. The electric push rod is fixedly installed on the inner side of the top end of the top cover. The side wall of the fixed frame is fixedly connected to the output end of the electric push rod. The second vibration motor is fixedly installed in the middle of the fixed frame. One end of the vibrating rod is fixedly connected to the output end of the second vibration motor. The limiting slot is opened at the top end of the top cover.

[0006] Optionally, the telescopic moving mechanism includes a storage slot, a limiting lifting slot, a second hydraulic cylinder, a support frame, a limiting slider, and moving rollers. The storage slot is located on the inner side of the bottom end of the base, the limiting lifting slot is located on the side wall of the storage slot, the second hydraulic cylinder is fixedly installed on the top end of the storage slot, the top end of the support frame is fixedly connected to the output end of the second hydraulic cylinder, the side wall of the limiting slider is fixedly connected to the side wall of the support frame, and the two ends of the moving rollers are rotatably connected to the middle of the support frame.

[0007] Optionally, an anti-slip pad is fixedly connected to the bottom of the base, and the anti-slip pad is made of rubber.

[0008] Optionally, the movable side plate is slidably connected to the inner wall of the segment mold by engaging with the fitting groove.

[0009] Optionally, several of the connecting blocks are slidably connected to the side wall of the limiting slide groove by engaging with it.

[0010] Optionally, the vibrating rod is fitted with a limiting slot.

[0011] Optionally, the side wall of the support column is provided with a through hole, and the output end of the motor rotates through the through hole and is fixedly connected to the side wall of the rotating connecting rod.

[0012] Optionally, the limiting slider is slidably connected to the side wall of the limiting lifting groove by fitting into the limiting lifting groove.

[0013] The technical effects achieved by this invention are as follows: (1) This solution sets up a pull-out demolding mechanism. Specifically, the first vibration motor is started to drive the vibration plate to vibrate, thereby driving the moving side plate to vibrate so that the internally formed concrete pipe segment is separated from the pipe segment mold during vibration. The first hydraulic cylinder is started to extend and drive the connecting block to slide in the limiting slide groove and drive the moving side plate to slide in the fitting groove to move out from one side of the pipe segment mold, thereby removing the formed pipe segment from the pipe segment mold. This achieves the purpose of effectively and quickly removing the pipe segment that is stuck to the inner wall of the pipe segment mold by vibration, effectively avoiding damage to the pipe segment caused by violent demolding. (2) By setting up a mixing mechanism, specifically by starting the motor to drive the rotating connecting rod to rotate and then drive the top cover to flip and cover the segment mold, by retracting the electric push rod to drive the fixing frame to descend, thereby driving the vibrator to be inserted into the segment mold from the limiting slot, and by starting the second vibration motor to drive the vibrator to vibrate and evenly mix the concrete, so that the concrete poured into the segment mold is fully and evenly filled in the segment mold, thereby effectively ensuring that the concrete is fully and evenly filled in the segment mold, avoiding the concrete from accumulating in the segment mold, resulting in uneven filling and voids, which would lead to a decrease in the final product quality. (3) By setting up a telescopic moving mechanism, specifically by extending the second hydraulic cylinder to drive the support frame to slide in the limiting lifting groove through the limiting slider on its side wall and extend out from the storage groove, so that the moving roller contacts the ground and lifts the whole structure. By pushing the base, the moving roller is rotated under force, thereby driving the whole structure to move. After moving to the use area, similarly, by retracting the second hydraulic cylinder, the support frame slides into the storage groove, so that the whole structure is grounded and supported and fixed by the base, thereby effectively improving the portability and mobility of the structure. It can be portable and moved according to the use needs without affecting its stability during use. (4) By setting anti-slip mats, specifically by using rubber anti-slip mats to increase the friction between the base and the ground, the structure can be stabilized and the support stability can be further improved during use, thus avoiding easy shaking and sliding due to force, which would affect normal use.

The movable side plate 403 is slidably connected to the inner wall of the tube segment mold 3 by mating with the mating groove 406. Several limiting grooves 407 are formed on the side wall of the tube segment mold 3. Several connecting blocks 402 are slidably connected to the side wall of the limiting grooves 407 by mating with the limiting grooves 407. The sticky tube segments are separated from the mold by the pull-out demolding mechanism 4 under vibration, and the formed tube segments are pulled out of the mold for quick demolding.

The vibrator 508 fits into the limiting slot 509, and the limiting slot 509 slides and limits the vibrator 508.

[0019] In some embodiments, see Figure 3 , Figure 6The telescopic moving mechanism 7 includes a storage slot 701, a limiting lifting slot 702, a second hydraulic cylinder 703, a support frame 704, a limiting slider 705, and moving rollers 706. The storage slot 701 is located inside the bottom end of the base 1 and stores the entire structure. The limiting lifting slot 702 is located on the side wall of the storage slot 701 and limits the sliding of the limiting slider 705. The second hydraulic cylinder 703 is fixedly installed at the top of the storage slot 701 and provides force to drive the support frame 704 forward. The support frame 704 is fixedly connected to the output end of the second hydraulic cylinder 703, and the moving roller 706 is rotated and supported by the support frame 704. The side wall of the limiting slider 705 is fixedly connected to the side wall of the support frame 704, and the moving limit of the support frame 704 is limited by the limiting slider 705. The limiting slider 705 is slidably connected to the side wall of the limiting lifting groove 702 by engaging with the limiting lifting groove 702. The two ends of the moving roller 706 are rotatably connected to the middle of the support frame 704, and the moving roller 706 is rotated by force to achieve portable movement.

[0020] In some embodiments, see Figure 1 , Figure 2 , Figure 3 , Figure 6 The bottom of the base 1 is fixedly connected to an anti-slip pad 6, which is made of rubber. The anti-slip pad 6 increases the friction between the base 1 and the ground to prevent slipping and stabilize the base, thus improving its support stability during use.

[0021] The working process and principle of this invention are as follows: In use, the second hydraulic cylinder 703 first extends, causing the support frame 704 to slide within the limiting lifting groove 702 via the limiting slider 705 on its side wall, extending out from the storage groove 701. This allows the moving roller 706 to contact the ground, lifting the entire structure. Pushing the base 1 causes the moving roller 706 to rotate, thus moving the entire structure. Once in the usage area, the second hydraulic cylinder 703 retracts, causing the support frame 704 to slide back into the storage groove 701, allowing the entire structure to land and be supported and fixed by the base 1. This effectively improves the portability and mobility of the structure, allowing for easy movement as needed without compromising its stability during use. Simultaneously, the use of rubber anti-slip pads 6 increases the friction between the base 1 and the ground, providing anti-slip stability and further enhancing the structure's support stability during use. This prevents swaying and slippage under stress, ensuring normal operation. Then, the concrete for preparing the tunnel segments is poured into the segment mold 3. The motor 502 starts, driving the rotating connecting rod 503 to rotate, which in turn causes the top cover 504 to flip and cover the segment mold 3. The retraction of the electric push rod 505 causes the fixing frame 506 to descend, thereby driving the vibrator 508 to insert into the segment mold 3 from the limiting slot 509. The second vibration motor 507 then activates the vibrator 508 to vibrate and evenly distribute the concrete, ensuring that the concrete poured into the segment mold 3 is fully and evenly filled. This effectively prevents uneven filling and voids caused by concrete accumulation in the segment mold 3, which could lead to a decrease in the final product quality. Finally, after the concrete solidifies and sets in the segment mold 3... The first vibration motor 404 is activated to drive the vibration plate 405 to vibrate, which in turn drives the moving side plate 403 to vibrate, causing the internally formed concrete segment to separate from the segment mold 3 during vibration. The first hydraulic cylinder 401 is activated to extend and drive the connecting block 402 to slide in the limiting groove 407, which in turn drives the moving side plate 403 to slide in the fitting groove 406 and move it out from one side of the segment mold 3. This removes the formed segment from the segment mold 3, effectively and quickly removing the segment that is stuck to the inner wall of the segment mold 3 by vibration, effectively avoiding damage to the segment caused by violent demolding.
