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

[0027] 1. In the present invention, through the arranged vibration adjustment assembly, the second motor drives the rotating shaft and the double-headed cam to rotate, so that the roller drives the connecting rod and the vibrating rod to continuously vibrate up and down, so as to vibrate around the embedded parts inside the external cement sleeper precast mold, improving the filling effect of the cement slurry around the embedded parts, reducing the influence of the tension of the embedded parts on the surrounding cement precast parts, and thus effectively improving the wrapping force of the sleeper cement precast parts on the embedded parts and the subsequent service durability. As the pouring surface inside the mold continuously rises, at this time, the hydraulic cylinder drives the lifting seat and the compaction seat to move upward. During the upward movement of the compaction seat, the liquid inside the main liquid bladder is conveyed to the secondary liquid bladder through the connecting pipe, the infusion frame and the pipeline, causing the secondary liquid bladder to expand and drive the cross plate and the first tapered block to move downward, adjusting the extrusion force on the roller, the connecting rod and the vibrating rod, so as to adjust the vibrating force of the vibrating rod on the embedded parts inside the mold, assisting in compensating for the attenuation of the vibration caused by the self-weight of the cement, and avoiding the phenomenon of honeycombing or segregation at the bottom of the embedded parts due to insufficient vibration, further improving the vibration stress transmission effect and production quality around the embedded parts.

[0028] 2. In the present invention, through the arranged lifting and compaction assembly, the hydraulic cylinder drives the lifting seat, the compaction seat and the pouring pipe to move downward, so as to ensure that there is always a proper distance between the pouring pipe and the cement slurry surface in the external cement sleeper precast mold, reducing the situation that cement materials bring air in, assisting in enhancing the density and production quality of the poured sleeper cement precast. By driving the hollow shaft and the convex block to rotate through the first motor, the compaction seat moves up and down continuously, flattening the cement slurry surface inside the external cement sleeper precast mold, making the surface of the formed isolation pier smoother. And the repeated compaction of the compaction seat can assist in removing the bubbles and pores inside the external cement precast mold, thereby effectively improving the finished product quality of the sleeper cement precast.

[0029] 3. In the present invention, through the arranged compaction adjustment assembly, during the movement of the toothed plate, the oil liquid inside the main oil bladder is conveyed to the inside of the secondary oil bladder through the fixed plate, causing the secondary oil bladder to expand and drive the arc-shaped block to move upward, so as to adjust the extrusion force of the convex block on the compaction seat. During the upward movement of the vibrating rod, the compaction force of the compaction seat on the cement materials is increased, enabling it to quickly fill the upward movement area of the vibrating rod, further increasing the collision effect and density among the cement materials around the embedded parts, thereby further improving the production quality of the device for the sleeper cement precast.

[0051] Working principle: When in use, install the external vibrating table and the external conveying unit at the appropriate positions on the bottom side inside the mounting frame 1. Then, place the external precast sleeper mold on the external conveying unit. The external conveying unit will drive the external precast sleeper mold to move and move it to the top of the external vibrating table. At this time, the connecting seat 502 is directly above the embedded part inside the external precast sleeper mold. Then, make the external feeding device transport the mixed cement material to the inside of the feeding hopper 2. The feeding hopper 2 will evenly transport the cement material to the inside of the external precast sleeper mold through the distributor 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. At the same time, start the first motor 405 and the second motor 503. Drive the hollow shaft 406 and the convex block 407 to rotate through the first motor 405. During the rotation of the convex block 407, it will continuously drive the compaction seat 403 to move downward to flatten the cement slurry surface inside the external precast sleeper mold. Drive the rotating shaft and the double-headed cam 504 to rotate through the second motor 503. During the rotation of the double-headed cam 504, it will continuously squeeze the vertical plate 505, the tooth plate 506 and the third spring 517. During the movement of the tooth plate 506, it will squeeze the roller 507 and the first spring 510, so that the roller 507 drives the connecting rod 508 and the vibrating rod 509 to vibrate up and down continuously to vibrate around the embedded part inside the external precast sleeper mold;

[0052] As the casting surface inside its mold continuously rises, the hydraulic cylinder 408 will drive the lifting seat 401 and the compaction seat 403 to move upward. During the upward movement of the compaction seat 403, it will squeeze the main liquid bladder 516, and the liquid inside the main liquid bladder 516 will be transported through the connecting pipe to the inside of the infusion frame 515. The infusion frame 515 will transport the liquid through the pipeline to the inside of the secondary liquid bladder 511, causing the secondary liquid bladder 511 to expand and drive the cross plate 513 and the first tapered block 514 to move downward, adjusting the use height at the bottom of the toothed plate 506, and further adjusting the extrusion force of the roller 507, the connecting rod 508, and the vibrating rod 509, so as to adjust the vibrating force of the vibrating rod 509 on the embedded parts inside the mold;

[0053] During the movement of the toothed plate 506, it will squeeze the main oil bladder 602 through the fixed plate 601, and the oil inside the main oil bladder 602 will be transported through the oil pipeline 603 to the inside of the fixed sleeve 604 and the hollow shaft 406. The hollow shaft 406 will transport it to the inside of the secondary oil bladder 606 through the circular through hole and the branch pipe 605, causing the secondary oil bladder 606 to expand and drive the arc-shaped block 607 to move upward, so as to adjust the extrusion force of the convex block 407 on the compaction seat 403. During the upward movement of the vibrating rod 509, the compaction force of the compaction seat 403 on the cement material is increased, which is convenient to use.

[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent replacements or changes, should be covered within the protection scope of the present invention.
