Description

Technical Field

[0001] This utility model relates to the technical field of casting and vibration devices, and in particular to a casting and vibration device for railway sleeper production. Background Technology

[0002] A concrete compaction device is a specialized piece of equipment used in the concrete construction process. Its main function is to vibrate and compact the concrete during pouring, thereby improving its density and strength. This device typically includes a hopper, guide pipe, vibrator, motor, and support frame. Through mechanical vibration, the compaction device removes air bubbles and excess water from the concrete, preventing quality problems such as honeycomb, pitting, and voids, thus enhancing the overall structural stability and durability of the concrete. This equipment is widely used in the construction of concrete structures in building engineering, bridges, high-speed railways, and other projects, significantly improving construction efficiency and project quality, ensuring that components meet design requirements.

[0003] In existing railway sleeper production processes, concrete pouring and vibration are typically carried out using separate equipment or manual vibration. Construction workers first pour pre-mixed concrete into the sleeper casting mold, then use a handheld vibrator or a fixed vibrating table to compact the concrete. This method suffers from uneven vibration energy distribution, difficulty in precisely controlling the amplitude, low vibration efficiency, high labor intensity, and potential safety hazards. Especially in large-scale assembly line production, manually inserting the vibrator is not only slow but also lacks flexibility in adjusting the vibration depth, leading to inconsistent concrete density within the sleeper and affecting the strength and durability of the finished product. Therefore, its use has certain limitations.

[0004] Based on this, we propose a sleeper production casting and vibration device to solve the problems mentioned above. Utility Model Content

[0011] Optionally, two sets of limiting plates are installed on the outer side of the mounting base plate. The limiting plates are matched with the limiting slot structure, and the limiting plates and the limiting slots are engaged. Guide plates are installed at the four corners of the side of the mounting base plate away from the limiting plates. Adjustment screw holes are opened through the middle of the two sets of guide plates, and guide sliding holes are opened through the middle of the other two sets of guide plates.

[0012] Optionally, two sets of lifting guide grooves are provided on both sides of the inner wall of the adjustment cavity.

[0013] Optionally, the adjusting screw and the adjusting screw hole are threaded together, and the guide slide rod and the guide slide hole are slidably fitted together.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] 1. The sleeper casting vibration device designed in this scheme, through the threaded engagement of the adjusting screw and adjusting screw hole, and the sliding engagement of the guide slide rod and guide slide hole, combined with the power output of the motor drive, can precisely control the horizontal lifting and lowering of the hoisting base plate. When the hoisting base plate drives the casting vibrator to descend into the sleeper casting mold, the vibration generated by the energized casting vibrator can fully compact the concrete in the mold. At the same time, with the help of the horizontal displacement function of the moving vehicle, the casting vibrator can uniformly compact the concrete in different positions in the mold, effectively improving the uniformity of concrete density, realizing the mass production of sleepers, improving production efficiency and product quality, and meeting the needs of large-scale production.

[0016] 2. The sleeper casting vibration device designed in this scheme significantly enhances the stability of the device's operation by setting up connecting seats, damping rods, compression springs, damping grooves, and damping blocks between the hoisting base plate and the casting vibrator. When the casting vibrator runs, the vibration waves generated are effectively offset and damped by the damping sliding cooperation between the damping rods and damping blocks and the damping groove, as well as the buffering effect of the compression springs. This not only prevents the vibration waves from being transmitted to the hoisting base plate and affecting its stability, but also avoids resonance between the hoisting base plate and the casting vibrator, achieving smooth operation of the device during the vibration process, extending the service life of the equipment, ensuring the continuity and reliability of the production process, and further improving the quality stability of sleeper production.

A motor drive 14 is installed on the top of the moving car body 2. An adjustment cavity 15 is provided in the middle of the moving car body 2. Hanging base plates 16 are provided on both sides of the inner wall of the adjustment cavity 15. A mold channel 17 is provided at the bottom of the adjustment cavity 15.

Through the engaging structure between the limiting plates 19 and the limiting slots 5, the hoisting base plate 4, which is equipped with the pouring vibrator 6 and the pouring vibrator rod 7 at the bottom, can be locked and secured inside the adjustment cavity 15.

[0028] Two sets of lifting guide grooves 23 are provided on both sides of the inner wall of the adjusting cavity 15. The lifting guide grooves 23 are structurally matched with the guide plate 20. One set of lifting guide grooves 23 is connected to the adjusting screw 24 through a bearing. The adjusting screw 24 is connected to the output end of the motor drive 14. The other set of lifting guide grooves 23 is also connected to the guide slide rod 25. Through the cooperation of the lifting guide grooves 23, adjusting screw 24, and guide slide rod 25, the moving car body 2 can flexibly adjust the depth of the pouring vibrator 7 inserted into the sleeper pouring mold 1 according to the usage situation, which can ensure To ensure the consistency of concrete density inside the sleeper casting mold 1, the adjusting screw 24 and the adjusting screw hole 21 are threaded together, and the guide slide rod 25 and the guide slide hole 22 are slidably connected. Through the structural design of the threaded connection between the adjusting screw 24 and the adjusting screw hole 21, and the slidable connection between the guide slide rod 25 and the guide slide hole 22, when the motor drive 14 installed on the top of the moving car body 2 is powered on, the lifting plate 4, which is limited and locked inside the adjusting cavity 15, can be adjusted to rise and fall horizontally because the adjusting screw 24 and the output end of the motor drive 14 are connected.

[0029] Working Principle: The sleeper casting vibration device designed in this scheme mainly consists of a mobile car body 2 and a casting vibration assembly 3. The casting vibration assembly 3 includes a lifting base plate 4 and a casting vibrator 6. The lifting base plate 4 is secured by limiting slots 5 on both sides and a limiting plate 19 installed on the outside of the hanging base plate 16. Because the limiting plate 19 and the limiting slots 5 are structurally matched and have a snap-fit ​​fit, the lifting base plate 4, which has the casting vibrator 6 and the casting vibrating rod 7 installed at the bottom, can be locked and secured inside the adjusting cavity 15. The adjusting cavity 15 is designed with a threaded fit between the adjusting screw 24 and the adjusting screw hole 21, and a sliding fit between the guide slide rod 25 and the guide slide hole 22. When the motor drive 14 installed on the top of the mobile car body 2 is powered on, because... The adjusting screw 24 is connected to the output end of the motor drive 14, allowing for horizontal raising and lowering of the lifting plate 4, which is locked inside the adjusting cavity 15. When the lifting plate 4 is lowered, the energized pouring vibrator 7 can be inserted into the sleeper pouring mold 1 to compact the concrete inside. By moving the horizontal displacement of the car body 2, the pouring vibrator 7 can compact different locations of the concrete in the sleeper pouring mold 1 at the same depth, effectively improving the consistency of the concrete density inside the sleeper pouring mold 1. Similarly, when the lifting plate 4 is raised, the pouring vibrator 7 can be removed from the concrete in the sleeper pouring mold 1. This cycle can be repeated to achieve large-scale assembly line production of sleeper pouring.

[0030] The sleeper pouring vibration device designed in this scheme uses a connecting seat 8 and a damping rod 9 installed between the hoisting base plate 4 and the pouring vibrator 6. The connecting seat 8 and the damping rod 9 are used in conjunction with a compression spring 11, a damping groove 12, and a damping block 13. Because the damping block 13 and the damping groove 12 are structurally matched and have a damping sliding fit, the pouring vibrator 6 with the pouring vibrator 7 installed at the bottom can be separated from the hoisting base plate 4. This can prevent the vibration waves generated by the operation of the pouring vibrator 7 from being transmitted to the hoisting base plate 4. At the same time, it can also cancel and buffer the vibration waves generated by the energized operation of the pouring vibrator 7, thus avoiding resonance between the hoisting base plate 4 and the pouring vibrator 7, which would affect the overall stability of the sleeper pouring vibration device.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
