Description

Technical Field

[0001] The present application relates to the technical field of concrete sleeper preparation equipment, and in particular to a high-strength concrete sleeper preparation equipment. Background Art

[0002] General status of related technologies in this field: In railway construction, sleepers are one of the important components, and their performance directly affects the safety and stability of the railway. Traditional sleepers are mostly made of wood or steel, but these materials have problems such as short service life and easy corrosion. In recent years, high-strength concrete sleepers have gradually become the mainstream choice due to their excellent mechanical properties and durability. However, the existing concrete sleeper preparation equipment still has many shortcomings in production efficiency, degree of automation and product quality.

[0003] There are three main ways to make concrete sleepers: manual, semi-automatic, or fully automatic production lines: Handmade: Early concrete sleepers were mostly made by hand, with workers pouring concrete into molds and then performing processes such as vibration and curing. This method has low production efficiency, difficult to guarantee quality, and high labor intensity.

[0004] Semi-automatic production line: With the development of technology, semi-automatic concrete sleeper production lines have emerged, which are partially automated through robotic arms and conveyor belts. Although production efficiency has improved, there are still problems such as more manual intervention, high equipment complexity, and high maintenance costs.

[0005] Fully automatic production line: The latest fully automatic production line uses advanced control systems and sensor technology to achieve full process automation from raw material mixing to finished product delivery. However, this type of equipment has high investment costs and requires high technical skills from operators.

[0006] Regarding the above-mentioned related technologies, the inventors believe that although the existing concrete sleeper preparation equipment has solved many problems in production to a certain extent, it still has obvious deficiencies in efficient production and quality control. For example, it is difficult for traditional feeding devices to achieve continuous and uniform mixing of concrete, resulting in large fluctuations in product quality; the accuracy of the transfer device is not high enough, which can easily cause mold position deviations and affect product consistency; the steel bar placement device is cumbersome to operate, which can easily lead to inaccurate steel bar positioning; the vibration effect of the vibrating device is poor, which may cause voids and cracks inside the concrete. The above problems have seriously affected the production efficiency and quality of concrete sleepers and are in urgent need of improvement. Summary of the invention

[0007] In order to solve the above problems, the present application provides a high-strength concrete sleeper preparation device.

[0009] By adopting the above technical scheme, the high-strength concrete sleeper preparation equipment can realize an automated production process, improve production efficiency and product quality. Specifically, the mixing drum and the inclined mixing blades of the feeding device can complete the feeding of concrete while mixing, reducing the quality problems caused by uneven mixing. The filter screen can further improve the mixing quality of concrete. The design of the feed plate and the lifting cylinder of the transfer device enables the sleeper mold to move quickly and accurately between various stations, reducing manual intervention and improving production continuity and stability. The downward pressure cylinder and the positioning plate structure of the steel bar placement device prevent inaccurate positioning of the steel bars, and replace the traditional manual discharge, enhance the overall strength of the sleeper, and greatly increase the production speed. The centrifugal device discharges the bubbles in the concrete sleeper through the action of centrifugal force. At the same time, the heavier aggregate particles will be subject to greater centrifugal force due to their greater inertia, so they are more likely to be pushed to the outside of the centrifuge. The lighter cement particles and water are subject to relatively less centrifugal force due to their smaller inertia, so they are more likely to move inward. This redistribution of particles helps to improve the particle distribution state of concrete. The concrete is made more compact, and the compression resistance of the sleeper is improved by enhancing the bonding force and optimizing the stress distribution. The shaping device further optimizes the quality of the sleeper, ensuring that the shape of the sleeper meets the design requirements and guarantees the appearance quality of the product.

When the sleeper mold is fully inserted into place, the sliding block returns to its original position under the action of the reset spring, so that the first clamping groove and the second clamping groove are switched through the guide groove connecting groove to fix the sleeper mold in the centrifugal hole. When the sleeper mold needs to be removed, it is only necessary to push the lifting frame through the lifting cylinder, and push the sliding block again, switching from the second clamping groove to the first clamping groove position, thereby releasing the clamping state, allowing the sleeper mold to fall on the lifting frame, follow the lifting frame to descend into the feed groove, and be urgently transported to the next station by the transfer device.

[0031] The following is combined with Figure 1-8 This application is described in further detail.

[0032] The embodiment of the present application discloses a high-strength concrete sleeper preparation device.

[0033] The high-strength concrete sleeper preparation equipment provided in the embodiment of the present application is referred to Figure 1 as well as Figure 2 , including a feeding device 1, a sleeper mold 2, a transfer device 3, a steel bar placement device 4, a centrifugal device 5, a shaping device 6 and a discharging device 7, wherein the coordination relationship between the devices is as follows: the feeding device 1 is used to stir and transport concrete to the sleeper mold 2; the transfer device 3 is used to move the sleeper mold 2; the steel bar placement device 4 is used to place steel bars in the sleeper mold 2; the centrifugal device 5 is used to evenly distribute the concrete in the sleeper mold 2; the shaping device 6 is used to assist the mold in concrete molding; and the discharging device 7 is used to discharge the processed mold. This configuration improves the production efficiency and quality stability of concrete sleepers.

[0034] refer to Figure 3Specifically, the feeding device 1 includes a feeding frame 101, and a mixing drum 102 is arranged on the feeding frame 101. A feeding port 103 and a discharging port 104 are arranged on the mixing drum 102, a screen 105 is arranged on the discharging port 104, and a discharging pipe 106 is connected to the discharging port 104. At least one mixing shaft 107 is horizontally arranged in the mixing drum 102, and a plurality of mixing blades 108 are arranged on the mixing shaft 107, and the mixing blades 108 are arranged obliquely. A mixing motor 109 is connected to the mixing shaft 107, and the mixing motor 109 is arranged on the feeding frame 101. This structure makes the concrete more uniform during the mixing process, avoids the phenomenon of particle agglomeration, and thus improves the quality of the concrete. For example, the mixing drum 102 can be made of carbon steel material, which has good strength and durability; the mixing blades 108 can be made of stainless steel material, which has good corrosion resistance and wear resistance.

[0035] The specific working process is as follows: concrete enters the mixing drum 102 through the feed port 103, the mixing motor 109 drives the mixing shaft 107 to rotate, and the mixing blades 108 are set at an angle, so that the concrete is fully mixed in the mixing drum 102 to avoid particle agglomeration. While being stirred, the concrete enters the discharge pipe 106 through the discharge port 104, is screened by the screen 105, and is finally transported to the sleeper mold 2.

[0036] refer to Figure 2 Specifically, the sleeper mold 2 includes a mold block 201, and a contour cavity 202 is provided on the mold block 201. The design of the contour cavity 202 can be adjusted according to actual needs to adapt to sleepers of different specifications. In addition, the mold block 201 can be made of high-strength stainless steel material, which has good corrosion resistance and wear resistance, and prolongs the service life of the mold. For example, the mold block 201 can be made of stainless steel material, which has excellent corrosion resistance and strength.

[0037] The specific working process is as follows: the sleeper mold 2 is moved by the transfer device 3 to below the discharge pipe 106 of the feeding device 1, and the concrete enters the contoured cavity 202 of the sleeper mold 2 through the discharge pipe 106 to fill the mold.

[0038] refer to Figure 3Specifically, the transfer device 3 includes a transfer frame 301, on which a rotating motor 302 is arranged, and the transmission end of the rotating motor 302 is arranged vertically. A feed plate 303 is arranged on the transmission end of the rotating motor 302, and a plurality of feed slots 304 are arranged on the feed plate 303. The sleeper mold 2 can be placed in the feed slot 304, and the profiling cavity 202 can move to the bottom of the discharge pipe 106. A lifting cylinder 305 is arranged in the feed slot 304, and a lifting frame 306 is arranged on the lifting cylinder 305. The lifting frame 306 is provided with a pushing slope 307; when the sleeper mold 2 is arranged in the feed slot 304, the sleeper mold 2 is arranged on the lifting frame 306. This design enables the sleeper mold 2 to be accurately transferred between the feeding device 1 and the centrifugal device 5, thereby improving the degree of automation of production. For example, the rotating motor 302 can be a servo motor, which has high precision and stable rotation speed; the lifting cylinder 305 can be a hydraulic cylinder, which has greater lifting force and stability.

[0039] The specific working process is as follows: first, the mold is placed in the feed trough 304 manually or by external machinery, and then the feed plate 303 is driven to rotate by the rotating motor 302 to move the feed trough 304 equipped with the sleeper mold 2 to each workstation in turn. Each device on each workstation processes the sleeper mold 2, such as the feeding device 1, the shaping device 6, etc. When centrifugal processing is required, the lifting cylinder 305 pushes the lifting frame 306 to rise, lifts the sleeper mold 2, and makes it leave the feed trough 304 and enter the positioning mechanism 504. After the centrifugal work is completed, the lifting cylinder 305 works again to put the centrifuged sleeper mold 2 from the positioning mechanism 504 back into the feed trough 304. When discharging, the lifting cylinder 305 pushes the lifting frame 306 to rise, lifts the sleeper mold 2, and then discharges the sleeper mold 2 through the discharging device 7.

[0040] refer to Figure 4 Specifically, the steel bar placement device 4 includes a steel bar placement support frame 401, on which a conveyor belt 402 is arranged, and the conveyor belt 402 can deliver the steel bars into the sleeper mold 2, and also includes a downward pressure cylinder 403 arranged on the steel bar placement support frame 401, and the transmission end of the downward pressure cylinder 403 is connected to a positioning plate 404, and at least two groups of torsion spring rods 405 are arranged on the positioning plate 404, and a pressing plate 406 is arranged on the torsion spring rod 405, and the positioning plate 404 can enter the sleeper mold 2. This design enables the steel bars to be accurately placed in the sleeper mold 2, avoids the error of manual operation, and improves the accuracy of steel bar placement. For example, the conveyor belt 402 can adopt a belt conveyor, which has a high transmission speed and stability; the downward pressure cylinder 403 can adopt a pneumatic cylinder, which has a fast response and reliable performance.

[0041] The specific working process is as follows: the steel bars are fed into the opening of the sleeper mold 2 through the conveyor belt 402, the downward pressure cylinder 403 drives the positioning plate 404 to descend, and the torsion spring rod 405 and the pressing plate 406 on the positioning plate 404 press the steel bars into the sleeper mold 2. While pressing, the steel bars are positioned from two directions to prevent the position of the steel bars in the mold from deviation.

[0042] refer to Figure 5 , Figure 6 as well as Figure 7 Specifically, the centrifugal device 5 includes a centrifugal support frame 501, a centrifugal motor 502 is arranged on the centrifugal support frame 501, a centrifugal plate 503 is arranged on the driving end of the centrifugal motor 502, a plurality of positioning mechanisms 504 are evenly arranged on the centrifugal plate 503, and the sleeper mold 2 can be arranged on the positioning mechanism 504. The mold positioning mechanism 504 includes a centrifugal hole 5041 arranged on the centrifugal plate 503, a positioning assembly 5042 is arranged on the centrifugal hole 5041, and the centrifugal hole 5041 can overlap with the feed groove 304 in the vertical direction. The locking assembly 5042 includes a mounting groove 50421 arranged on one side of the centrifugal hole 5041, a locking rod 50422 is arranged on the mounting groove 50421, and also includes a sliding block 50423 slidably connected in the mounting groove 50421, a one-way slope 50424 is arranged on the sliding block 50423, one end of the sliding block 50423 is connected to a return spring 50425, and the other end of the return spring 50425 is connected to the mounting groove 50421, a first locking groove 50426 is arranged in the sliding block 50423, a first guide groove 50427 is arranged on one side of the first guide groove 50427, a connecting groove 50428 is arranged on one side of the connecting groove 50428, and a second guide groove 50429 is arranged on one side of the second guide groove 50429. A second locking groove 50430 is arranged on one side of the second guide groove 50429. This design allows the sleeper mold 2 to remain stable during the centrifugal process, avoiding product quality problems caused by mold offset. For example, the centrifugal motor 502 can be a variable frequency motor, which has the characteristics of a wide speed range and stable operation; the centrifugal plate 503 can be made of cast iron material, which has good rigidity and wear resistance.

[0043] The specific working process is as follows: the sleeper mold 2 is moved to the positioning mechanism 504 of the centrifugal plate 503 through the transfer device 3. Before the sleeper mold 2 enters the centrifugal hole 5041, the locking stem is located in the first locking groove 50426, and the one-way slope 50424 is pushed by the positioning frame, the positioning block moves, and the reset spring 50425 is compressed. At the same time, the locking rod 50422 passes through the first guide groove 50427, the connecting groove 50428, and the second guide groove 50429 and enters the second locking groove 50430. At this time, the sleeper mold 2 is located above the sliding block 50423, and then the lifting frame 306 moves down. At this time, the sleeper mold 2 is placed in the centrifugal hole 5041, and then the centrifugal motor 502 is started, driving the centrifugal plate 503 to rotate at high speed. The locking assembly 5042 on the centrifugal plate 503 and the centrifugal hole 5041 cooperate to prevent the sleeper mold 2 from falling, so that it remains stable during the centrifugal process. The centrifugal action makes the concrete evenly distributed in the mold, eliminating internal bubbles and cavities. At the same time, the heavier aggregate particles are pushed to the outside of the centrifuge due to their greater inertia, while the lighter cement particles and water move to the inside due to their smaller inertia. This redistribution of particles helps to improve the particle distribution state of concrete, making the concrete more compact, and improves the compression resistance of the sleeper by enhancing the bonding force and optimizing the stress distribution. After the centrifugal work is completed, the centrifugal hole 5041 overlaps with the feed groove 304 again, and then the lifting cylinder 305 works again to make the lifting frame 306 move upward, and then the lifting frame 306 pushes the one-way slope 50424, the positioning block moves, the reset spring 50425 is compressed, and at the same time the positioning rod 50422 passes through the second guide groove 50429, the connecting groove 50428, and the first guide groove 50427 and then enters the first positioning groove 50426, and then the positioning block is reset, and then the lifting frame 306 with the sleeper mold 2 descends into the feed groove 304.

[0044] refer to Figure 5 Specifically, the shaping device 6 includes a shaping support frame 601, on which a downward pressure cylinder 403 is arranged, the transmission end of the downward pressure cylinder 403 points to the feed plate 303, and the transmission end of the downward pressure cylinder 403 is provided with a shaping plate 603. This design enables the concrete to be compacted in the mold, reduces the internal gap, and improves the density and strength of the product. For example, the downward pressure cylinder 403 can be an electric cylinder, which has a higher pressing force and stability.

[0045] The specific working process is as follows: after the sleeper mold 2 is centrifuged, the transfer device 3 moves it to the working station of the shaping device 6, and the downward pressure cylinder 403 drives the shaping plate 603 to descend. The shaping plate 603 applies pressure to the concrete in the mold to make the concrete more compact, reduce internal voids, improve the strength of the product, and adjust the shape of the product at the same time.

[0046] refer to Figure 8Specifically, the discharging mechanism includes a discharging frame 701, on which a discharging cylinder 702 is arranged, the discharging cylinder 702 is arranged horizontally, and a discharging plate 703 is arranged at the driving end of the discharging cylinder 702. This design enables the processed sleeper mold 2 to be discharged smoothly, thereby improving production efficiency. For example, the discharging cylinder 702 can be a pneumatic cylinder with fast response and reliable performance; the discharging plate 703 can be made of steel plate material with high strength and wear resistance.

[0047] The specific working process is as follows: after the sleeper mold 2 is shaped, the lifting gas works to push the sleeper mold 2 out of the feed slot 304, and then the discharge cylinder 702 drives the discharge plate 703 forward to push the sleeper mold 2 out of the transfer rack 301, so that it can be discharged smoothly and enter the next process.

The design of the mixing drum 102 and the mixing blade 108 of the feeding device 1 makes the concrete mixing more uniform and avoids the phenomenon of particle agglomeration. The precise positioning and jacking cylinder 305 design of the transfer device 3 enable the sleeper mold 2 to be smoothly transferred between various stations.
