Description

Technical Field

[0001] This invention belongs to the field of cement precast component production technology, and particularly relates to a cement precast component production device for railways. Background Technology

[0002] In railway construction, railway sleepers are the core load-bearing components of railway track structures. Their performance optimization is directly related to the safety, durability, and economy of the railway system. Among them, precast concrete sleepers have become an inevitable choice for modern railways due to their high cost-effectiveness, long service life, and excellent stability. Therefore, it is necessary to use equipment to prefabricate concrete sleepers.

[0003] For example, Chinese patent document (CN108705652B) discloses a manufacturing apparatus and method for precast cement concrete components, including a feeding rack. The feeding rack has a feeding hopper at its top, a fixing rod on the outside of the feeding hopper, and a support plate at the bottom of the fixing rod. The support plate is located inside the support rack, and a baffle is located at the top of the support plate, which is adapted to the discharge port of the feeding hopper. An mounting plate is located below the support plate on the inner side of the support rack, a metering bucket at the bottom of the mounting plate, and a baffle plate at the top of the mounting plate. This invention uses the metering bucket to measure cement, saving labor and improving feeding accuracy. (The last sentence appears to be incomplete and possibly refers to a different invention.) The vibrator flattens the cement, replacing the traditional manual smoothing, resulting in a smoother product surface that meets the requirements of wall decoration, improving product quality, and achieving a product qualification rate of up to 95%, greatly increasing output. However, during the processing of railway sleepers, the device relies solely on the vibrator to vibrate them. The tension of the embedded parts inside the sleepers generates radial constraint forces around them, forming a local stiffness enhancement zone. If the vibration force is too small, the cement density around the embedded parts will be poor. If the vibration force is too large, it may cause segregation of the cement slurry inside the mold, thus affecting the production quality of the precast railway sleeper cement parts. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to address the problem that in the existing technology for processing railway sleepers, relying solely on a vibrator to vibrate the sleeper results in radial constraint forces generated around the embedded parts by the tension inside the sleeper, forming a local stiffness enhancement zone. If the vibration force is too small, the cement density around the embedded parts will be poor; if the vibration force is too large, the cement slurry inside the mold may segregate, thus affecting the production quality of precast railway sleeper components.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In this invention, the vibration adjustment component enables the second motor to drive the rotating shaft and double-headed cam to rotate, causing the roller to drive the connecting rod and vibrating rod to vibrate continuously up and down. This vibrates the area around the embedded parts inside the external cement sleeper precast mold, improving the filling effect of the cement slurry around the embedded parts and reducing the impact of the tension of the embedded parts on the surrounding cement precast parts. This effectively improves the bonding force of the cement sleeper precast parts to the embedded parts and their subsequent service durability. As the pouring surface inside the mold rises, the hydraulic cylinder drives the lifting seat and... As the compaction seat moves upward, it transports the liquid inside the main liquid bladder to the secondary liquid bladder through the connecting pipe, delivery frame, and pipeline. This causes the secondary liquid bladder to expand and move the horizontal plate and the first conical block downward. The squeezing force of the rollers, connecting rods, and vibrating rods is adjusted to regulate the vibration force of the vibrating rods on the embedded parts inside the mold. This helps to compensate for the attenuation of the vibration at the bottom due to the weight of the cement, and avoids honeycombing or segregation at the bottom of the embedded parts due to insufficient vibration. This further improves the vibration stress transmission effect and production quality around the embedded parts.

[0028] 2. In this invention, the hydraulic cylinder, through the lifting and compaction assembly, drives the lifting seat, compaction seat, and pouring pipe downwards to ensure that there is always a suitable distance between the pouring pipe and the cement slurry surface in the external cement sleeper precast mold. This reduces the possibility of air being introduced into the cement material, thus enhancing the density and production quality of the poured cement sleeper precast components. The first motor drives the hollow shaft and protrusion to rotate, causing the compaction seat to move up and down continuously, flattening the cement slurry surface inside the external cement sleeper precast mold. This results in a smoother surface for the formed isolation pier. Furthermore, the repeated compaction by the compaction seat helps to eliminate air bubbles and pores inside the external cement precast mold, thereby effectively improving the finished quality of the cement sleeper precast components.

[0029] 3. In this invention, through the compaction adjustment component, the toothed plate will transport the oil inside the main oil bladder to the auxiliary oil bladder through the fixed plate during the movement, causing the auxiliary oil bladder to expand and drive the arc-shaped block to move upward, so as to adjust the squeezing force of the protrusion on the compaction seat. During the upward movement of the vibrator, the compaction force of the compaction seat on the cement material is increased, so that it quickly fills the upward movement area of ​​the vibrator, further increasing the collision effect and compaction between the cement materials around the embedded parts, thereby further improving the production quality of the railway sleeper cement precast parts of the device.

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

[0044] Please see Figures 1-11 The present invention provides a technical solution: a production device for precast cement components for railways, including a mounting frame 1 and a connecting frame 3. The bottom of the connecting frame 3 is provided with a lifting and compaction component 4.

[0045] The vibration adjustment assembly 5 includes a mounting frame 501 and multiple connecting seats 502. A connecting rod 508 is slidably connected inside the connecting seat 502. A roller 507 is fixedly connected to the top of the connecting rod 508. The top of the multiple rollers 507 is provided with the same toothed plate 506. A force adjustment unit is provided on one side inside the toothed plate 506. A vibrator 509 for vibrating the cement embedded part is fixedly connected to the bottom of the connecting rod 508. The vibrator 509 is driven to move up and down continuously by the toothed plate 506 and the force adjustment unit to adjust the vibration force around the poured cement embedded part. The mounting frame 501 is set inside the compaction seat 403, and the bottom of the mounting frame 501 is fixedly connected to the inner wall of the compaction seat 403. A second motor is fixedly connected to the bottom side inside the mounting frame 501. 503, one end of the output shaft of the second motor 503 is fixedly connected to a double-headed cam 504 via a rotating shaft. Vertical plates 505 are provided on both sides of the double-headed cam 504. The side of the vertical plate 505 away from the double-headed cam 504 is fixedly connected to a toothed plate 506. An inner cavity is opened on one side of the toothed plate 506, located on the side away from the vertical plate 505 and directly above the roller 507. Multiple third springs 517 are provided on the lower side of the toothed plate 506. The two sides of the third springs 517 are fixedly connected to the vertical plate 505 and the inner wall of the mounting frame 501, respectively. The toothed plate 506 is slidably connected inside the mounting frame 501. The connecting seat 502 is fixedly connected inside the compaction seat 403. The vibrating rod 509 is slidably sealed inside the connecting seat 502. A connecting rod 508 is sleeved on the outer periphery. A first spring 510 is fixedly connected to the top of the vibrating rod 509 and the inner wall of the connecting seat 502 on both sides. The force adjustment unit includes a secondary liquid bladder 511, which is located inside the inner cavity. The inner cavity has multiple limiting through holes, which are located inside the toothed plate 506. The top of the secondary liquid bladder 511 is fixedly connected to the inner wall of the toothed plate 506. A horizontal plate 513 is fixedly connected to the bottom of the secondary liquid bladder 511. Multiple first conical blocks 514 are fixedly connected to the bottom of the horizontal plate 513. The first conical blocks 514 are slidably connected inside the limiting through holes. The limiting through holes are on the same axis as the roller 507, and the width of the limiting through holes is smaller than the width of the roller 507. Second springs 512 are provided on both sides of the secondary liquid bladder 511. 2. Both sides are fixedly connected to one side of the horizontal plate 513 and the inner wall of the toothed plate 506, respectively. One side of the auxiliary liquid bladder 511 is connected to the infusion frame 515 through a pipe. The pipe is equipped with a pressure valve and a flow valve. The infusion frame 515 is set inside the mounting frame 501, and the top of the infusion frame 515 is fixedly connected to the inner wall of the mounting frame 501. One side of the infusion frame 515 is connected to the main liquid bladder 516 through a connecting pipe. The main liquid bladder 516 is set outside the mounting frame 501, and both sides of the main liquid bladder 516 are fixedly connected to the top of the compaction seat 403 and the bottom of the lifting seat 401, respectively. The connecting frame 3 is fixedly connected to the inside of the mounting frame 1 by screws. The cross-sectional shape of the connecting frame 3 is set as I. The feeding hopper 2 is fixedly connected inside the mounting frame 1. The bottom end of the feeding hopper 2 extends to the bottom of the connecting frame 3.A disperser 7 is installed at the bottom of the feed hopper 2, extending to the bottom of the connecting frame 3. Multiple casting pipes 8 are installed on both sides of the disperser 7. The bottom of each casting pipe 8 passes through the compaction seat 403 and extends to its bottom. The casting pipe 8 is configured as a telescopic sealing pipe.

[0046] Detailed Implementation: The external vibration table and external conveying unit are installed in a suitable position on the bottom side of the mounting frame 1. Then, the external cement sleeper precast mold is placed on the external conveying unit. The external conveying unit will move the external cement sleeper precast mold to the top of the external vibration table. At this time, the connecting seat 502 is directly above the embedded parts inside the external cement sleeper precast mold. Then, the external feeding device conveys the mixed cement material into the feed hopper 2. The feed hopper 2 will evenly convey the cement material into the external cement sleeper precast mold through the disperser 7 and the pouring pipe 8 at the bottom. At the same time... Hydraulic cylinder 408 drives lifting seat 401, compaction seat 403, and pouring pipe 8 downwards to ensure that there is always a suitable distance between the pouring pipe 8 and the cement slurry surface in the external cement sleeper precast mold. This reduces the possibility of air being introduced by the cement material, thus enhancing the density and production quality of the poured cement sleeper precast components. Second motor 503 drives the rotating shaft and double-headed cam 504 to rotate. During rotation, the double-headed cam 504 continuously compresses the vertical plate 505, toothed plate 506, and third spring 517. Meanwhile, the toothed plate 506, during its movement, compresses the roller 507 and the first spring 510, causing the roller to... Wheel 507 drives connecting rod 508 and vibrating rod 509 to continuously vibrate up and down at high frequency, thereby compacting the area around the embedded parts inside the external cement sleeper precast mold. This improves the filling effect of cement slurry around the embedded parts, reduces the impact of the embedded parts' tension on the surrounding cement precast parts, and effectively improves the binding force of the cement sleeper precast parts on the embedded parts and its subsequent service durability. As the pouring surface inside the mold continues to rise, hydraulic cylinder 408 drives lifting seat 401 and compaction seat 403 to move upward. During the upward movement, compaction seat 403 squeezes the main liquid bladder 516, forcing the liquid inside the main liquid bladder 516 through the connecting rod 507. The infusion container 515 delivers liquid to the inside of the infusion frame 515, which then delivers the liquid to the inside of the auxiliary liquid bladder 511 through the pipeline. This causes the auxiliary liquid bladder 511 to expand and move the horizontal plate 513 and the first conical block 514 downwards, adjusting the working height of the bottom of the toothed plate 506. This, in turn, adjusts the squeezing force of the roller 507, connecting rod 508, and vibrating rod 509, thereby adjusting the vibration force of the vibrating rod 509 on the embedded parts inside the mold. This can compensate for the attenuation of the lower vibration due to the weight of the cement, and prevent honeycomb or segregation at the bottom of the embedded parts due to insufficient vibration. This further improves the vibration stress transmission effect and production quality around the embedded parts.

[0047] Hydraulic cylinders 408 are fixedly connected to both sides of the top of the lifting seat 401. The hydraulic cylinders 408 are fixedly connected to the bottom of the connecting frame 3 via mounting seats. Connecting cylinders 402 are fixedly connected to the four corners of the bottom of the lifting seat 401. A fifth spring is fixedly connected to the top side inside the connecting cylinder 402. A limit slide is fixedly connected to the bottom of the fifth spring. A limit fixing rod is fixedly connected to the bottom of the limit slide. The bottom end of the limit fixing rod extends to the outside of the connecting cylinder 402 and is fixedly connected to the top of the compaction seat 403. The limit slide and the limit fixing rod are slidably connected inside the connecting cylinder 402. The lifting seat 401... 1. Fixing brackets 404 are fixedly connected to both sides of the bottom. The same hollow shaft 406 is rotatably connected inside the two fixing brackets 404. One end of the hollow shaft 406 extends to the outside of the fixing bracket 404 and is fixedly connected to the first motor 405. The first motor 405 is fixedly connected to the outer wall of the fixing bracket 404 through the support seat. The outer periphery of the hollow shaft 406 is fixedly connected to the inner wall of the protrusion 407. A circular through hole is opened at the junction of the hollow shaft 406 and the protrusion 407. The protrusion 407 is located between the two fixing brackets 404 and is located on the top of the compaction seat 403.

[0048] Detailed implementation method: Start the first motor 405 and the second motor 503. The first motor 405 drives the hollow shaft 406 and the protrusion 407 to rotate. During the rotation, the protrusion 407 will continuously drive the compaction seat 403 to move downward, flattening the cement slurry surface inside the external cement sleeper precast mold. This makes the surface of the formed isolation block smoother. The repeated compaction of the compaction seat 403 can help eliminate air bubbles and pores inside the external cement precast mold, thereby effectively improving the finished quality of the cement sleeper precast component.

[0049] The compaction adjustment assembly 6 includes a secondary oil bladder 606, which is disposed inside the cavity. The bottom of the secondary oil bladder 606 is fixedly connected to the inner wall of the protrusion 407, and an arc-shaped block 607 is fixedly connected to the top of the secondary oil bladder 606. The arc-shaped block 607 is slidably connected inside the cavity. A fourth spring 608 is provided on both sides of the secondary oil bladder 606. The two sides of the fourth spring 608 are fixedly connected to one side of the arc-shaped block 607 and the inner wall of the protrusion 407, respectively. A branch pipe 605 is connected to one side of the secondary oil bladder 606, and the other end of the branch pipe 605 is connected to a circular part inside the hollow shaft 406. The through holes are connected, and the hollow shaft 406 is rotatably connected to the fixed sleeve 604 at the end away from the first motor 405. One side of the fixed sleeve 604 is fixedly connected to the outer wall of the fixed frame 404. The side of the fixed sleeve 604 away from the fixed frame 404 is connected to the oil supply pipe 603. The other end of the oil supply pipe 603 extends into the interior of the compaction seat 403 and is connected to the main oil bladder 602. One side of the main oil bladder 602 is fixedly connected to the inner wall of the compaction seat 403. The other side of the main oil bladder 602 is fixedly connected to the fixed plate 601. The other side of the fixed plate 601 is fixedly connected to the two toothed plates 506.

[0050] Detailed implementation: During movement, the toothed plate 506 compresses the main oil bladder 602 via the fixed plate 601, transporting the oil inside the main oil bladder 602 to the fixed sleeve 604 and the hollow shaft 406 through the oil supply pipe 603. The hollow shaft 406 then transports the oil to the auxiliary oil bladder 606 through the circular through hole and the branch pipe 605, causing the auxiliary oil bladder 606 to expand and drive the arc-shaped block 607 to move upward. This allows the protrusion 407 to adjust the compressive force of the compaction seat 403. As the vibrator 509 moves upward, the compressive force of the compaction seat 403 on the cement material is increased, allowing it to quickly fill the upward-moving area of ​​the vibrator 509. This further increases the collision effect and compaction of the cement material around the embedded part, thereby further improving the production quality of the railway sleeper cement precast parts produced by the device.

[0051] Working principle: In use, the external vibration table and external conveying unit are installed in a suitable position on the bottom side of the mounting frame 1. Then, the external cement sleeper precast mold is placed on the external conveying unit. The external conveying unit will drive the external cement sleeper precast mold to move and move it to the top of the external vibration table. At this time, the connecting seat 502 is directly above the embedded parts inside the external cement sleeper precast mold. Then, the external feeding device will convey the mixed cement material into the feed hopper 2. The feed hopper 2 will evenly convey the cement material into the external cement sleeper precast mold through the disperser 7 and the pouring pipe 8 at the bottom. At the same time, the hydraulic cylinder 408 will drive the lifting seat 401, the compaction seat 403 and the pouring pipe 8 to move downward. Simultaneously, the first... Motor 405 and second motor 503 drive the hollow shaft 406 and protrusion 407 to rotate via the first motor 405. During the rotation, the protrusion 407 continuously drives the compaction seat 403 to move downward, flattening the cement slurry surface inside the external cement sleeper precast mold. The second motor 503 drives the rotating shaft and double-headed cam 504 to rotate. During the rotation, the double-headed cam 504 continuously squeezes the vertical plate 505, toothed plate 506 and third spring 517. During the movement, the toothed plate 506 squeezes the roller 507 and the first spring 510, causing the roller 507 to drive the connecting rod 508 and vibrating rod 509 to vibrate up and down continuously, thereby vibrating around the embedded parts inside the external cement sleeper precast mold.

[0052] As the pouring surface inside the mold rises, the hydraulic cylinder 408 drives the lifting seat 401 and the compaction seat 403 to move upward. During the upward movement, the compaction seat 403 squeezes the main liquid bladder 516, and the liquid inside the main liquid bladder 516 is transported to the liquid delivery frame 515 through the connecting pipe. The liquid delivery frame 515 then transports the liquid to the auxiliary liquid bladder 511 through the pipe, causing the auxiliary liquid bladder 511 to expand and drive the horizontal plate 513 and the first conical block 514 to move downward. This adjusts the working height of the bottom of the toothed plate 506, and in turn adjusts the squeezing force of the roller 507, the connecting rod 508 and the vibrating rod 509, thereby adjusting the vibration force of the vibrating rod 509 on the embedded parts inside the mold.

[0053] During movement, the toothed plate 506 compresses the main oil bladder 602 via the fixed plate 601, transporting the oil inside the main oil bladder 602 to the fixed sleeve 604 and the hollow shaft 406 through the oil supply pipe 603. The hollow shaft 406 then transports the oil to the auxiliary oil bladder 606 through the circular through hole and the branch pipe 605, causing the auxiliary oil bladder 606 to expand and drive the arc-shaped block 607 to move upward. This allows the protrusion 407 to adjust the compressive force of the compaction seat 403. As the vibrator 509 moves upward, the compaction force of the compaction seat 403 on the cement material is increased, making it convenient to use.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
