Description

Equipment for processing polyurethane concrete composite railway sleepers Technical Field

[0001] This application relates to the technical field of concrete sleeper production equipment, and in particular to equipment for processing polyurethane concrete composite sleepers. Background Technology

[0002] In the current rapid development of railway construction, the performance requirements for railway sleepers are becoming increasingly stringent. Polyurethane concrete composite sleepers have emerged to address this, distinguishing themselves among various sleeper types due to their superior comprehensive performance. With high strength, they can stably support the track structure, withstanding the enormous pressure and impact generated by train operation, effectively ensuring track stability. Their excellent durability makes them resistant to long-term exposure to wind and sun, rain erosion, and drastic temperature changes, significantly extending the sleeper's service life and reducing railway maintenance costs. Simultaneously, these composite sleepers exhibit excellent adaptability to track structures, perfectly fitting both conventional railway lines and railway construction under special geological conditions, precisely meeting the diverse needs of railway construction. As a result, polyurethane concrete composite sleepers are gradually replacing traditional sleepers, their application in railway construction is continuously expanding, and market demand is showing a rapid growth trend.

[0003] Currently, equipment for processing polyurethane concrete composite railway sleepers exhibits numerous problems in actual production. In related technologies, workers typically inject grout directly into a mold, adding polyurethane binder during the grouting process, followed by mixing the concrete within the mold. This process not only lacks automation but is also prone to inconsistent production quality due to human factors, impacting production efficiency. Therefore, developing equipment for processing polyurethane concrete composite railway sleepers that can effectively improve production efficiency is of significant practical importance. Summary of the Invention

[0004] To improve the production efficiency of polyurethane concrete composite railway sleepers, this application provides equipment for processing polyurethane concrete composite railway sleepers.

[0005] The equipment for processing polyurethane concrete composite railway sleepers provided in this application adopts the following technical solution:

[0006] A device for processing polyurethane concrete composite railway sleepers includes a polyurethane storage tank and a concrete storage tank. The polyurethane storage tank and the concrete storage tank are connected to the same mixing tank. A vibrating table is provided on one side of the mixing tank, and a railway sleeper mold is placed on the vibrating table. A feeding mechanism for adding polyurethane concrete mixture to the railway sleeper mold is provided at the upper end of the vibrating table. The mixing tank is connected to the feeding mechanism. A conveyor is provided on one side of the vibrating table, and a pushing component is provided on one side of the conveyor to push the railway sleeper mold on the conveyor onto the vibrating table.

[0007] By adopting the above technical solution, the polyurethane storage tank and the concrete storage tank are mixed through a mixing tank, ensuring uniform mixing and improving the quality of the sleepers. The vibrating table effectively eliminates air bubbles in the sleeper molds, improving the molding effect. The design of the feeding mechanism allows the mixed polyurethane concrete to be precisely added to the sleeper molds, ensuring uniform filling. The combined use of the conveyor and pushing components enables automated transmission and positioning of the sleeper molds, improving the production efficiency of polyurethane concrete composite sleepers and reducing labor costs.

[0008] Optionally, the feeding mechanism includes a support frame, a feeding plate slidably connected to the support frame, an output pipe fixed and connected to the mixing tank, a material control valve installed on the output pipe, one end of the output pipe away from the mixing tank being fixedly connected to the feeding plate, the outlet of the output pipe facing the vibrating table, and a driving component for driving the feeding plate to slide along the length of the support frame on the feeding plate.

[0009] By adopting the above technical solution, the feed plate, which is slidably connected on the support frame, can move along the length of the support frame. This, combined with the output pipe, allows for precise addition of polyurethane concrete mixture to the sleeper mold on the vibrating table, achieving a uniform distribution effect. The control valve effectively controls the flow rate of the mixture, ensuring the accuracy of the addition amount. The introduction of the drive assembly further enhances the automation level of the feed plate, making the distribution process more efficient and stable.

[0010] Optionally, the drive assembly includes multiple pairs of pulleys disposed at the lower end of the feed plate, with a common drive motor between the same pair of pulleys. The output shaft of the drive motor is connected to the pulley shaft. The drive motor is fixedly connected to the lower end of the feed plate, and the pulleys are slidably connected to the support frame.

[0011] By adopting the above technical solution, the drive motor rotates the pulley, allowing the feed plate to slide smoothly along the length of the support frame, thereby achieving precise delivery of the polyurethane concrete mixture. The cooperation between the pulley and the support frame reduces frictional resistance, improves the stability and flexibility of the feed plate's movement, and ensures that the mixture can evenly cover different areas of the sleeper mold.

[0012] Optionally, the pushing component includes a placement platform, on which a pushing cylinder is fixedly connected. A push plate is fixedly connected to the output shaft of the pushing cylinder, and the pushing cylinder is capable of pushing the sleeper mold on the conveyor platform toward the vibrating platform.

[0013] By adopting the above technical solution, the sleeper mold on the conveyor can be automatically pushed and accurately moved from the conveyor to the vibrating table, ensuring the smooth transfer of the sleeper mold during the processing, reducing manual intervention, lowering labor intensity, and improving production safety.

[0014] Optionally, the conveyor end of the conveyor table is provided with a baffle for blocking the sleeper mold.

[0015] By adopting the above technical solution, the baffle at the end of the conveyor can effectively restrict the sleeper mold to the end of the conveyor, ensuring that the sleeper mold is accurately delivered to the vibrating table.

[0016] Optionally, the vibrating table includes a base plate and a placement plate. Multiple support rods are fixedly connected to the base plate. The end of each support rod away from the base plate is hinged to the lower end of the placement plate. A vibrating motor is installed at the lower end of the placement plate.

[0017] By adopting the above technical solution, the placement plate can vibrate under the action of the vibrating motor, thereby effectively eliminating air bubbles in the polyurethane concrete mixture in the sleeper mold and improving the density and strength of the composite sleeper. At the same time, the hinged structure allows the placement plate to remain stable during vibration, reducing the risk of equipment damage or impact on processing accuracy caused by excessive vibration.

[0018] Optionally, a first connecting pipe is fixedly connected and communicates between the polyurethane storage tank and the mixing tank, and a first discharge valve is installed on the first connecting pipe. A second connecting pipe is fixedly connected and communicates between the concrete storage tank and the mixing tank, and a second discharge valve is installed on the second connecting pipe.

[0019] By adopting the above technical solutions, the inflow of polyurethane materials or concrete can be precisely controlled, reducing the occurrence of excessive or insufficient amounts.

[0020] Optionally, the conveyor is configured as a roller conveyor, wherein the axis of the conveying roller in the roller conveyor is parallel to the extension and retraction direction of the push cylinder.

[0021] By adopting the above technical solution, setting the conveyor table as a roller conveyor table can reduce the frictional resistance of the sleeper mold during the conveying process and improve the conveying efficiency and stability.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. It allows for precise addition of the mixed polyurethane concrete into the sleeper mold, ensuring uniform filling. The combined use of the conveyor and pushing components enables automated transport and positioning of the sleeper mold, improving the production efficiency of polyurethane concrete composite sleepers and reducing labor costs;

[0024] 2. The baffle at the end of the conveyor can effectively restrict the sleeper mold at the end of the conveyor, ensuring that the sleeper mold is accurately delivered to the vibrating table.

[0025] 3. It achieves uniform material distribution. The control valve effectively regulates the flow rate of the mixture, ensuring precise dosage. The introduction of the drive assembly further enhances the automation of the feed plate, making the material distribution process more efficient and stable. Attached Figure Description

[0030] The present application will be further described in detail below with reference to Figures 1-3.

[0031] An embodiment of this application is: a device for processing polyurethane-concrete composite railway sleepers, referring to Figure 1, comprising a polyurethane storage tank 1, a concrete storage tank 2, and a mixing tank 3. A first connecting pipe 8 is fixedly connected and communicates with the polyurethane storage tank 1 and the mixing tank 3, and a first discharge valve 81 is installed on the first connecting pipe 8. A second connecting pipe 9 is fixedly connected and communicates with the concrete storage tank 2 and the mixing tank 3, and a second discharge valve 91 is installed on the second connecting pipe 9.

[0032] Referring to Figures 1 and 2, a vibrating table 4 is provided on one side of the mixing tank 3. The vibrating table 4 is used to place the sleeper mold 11. The vibrating table 4 includes a base plate 41 and a placement plate 42, which are arranged in parallel. Multiple support rods are fixedly connected to the base plate 41. The end of the support rod away from the base plate 41 is hinged to the lower end of the placement plate 42. In this embodiment, the hinge of the support rod is a ball joint. Two vibrating motors 43 are installed at the lower end of the placement plate 42.

[0033] When the vibratory rail mold is placed on the vibratory table 4, the vibratory motor 43 can be started to drive the placement plate 42 to vibrate. The placement plate 42 can then vibrate under the action of the vibratory motor 43, thereby reducing the air bubbles in the polyurethane concrete mixture in the sleeper mold 11.

[0034] A conveyor platform 6 is provided on one side of the vibrating table 4. The conveyor platform 6 is a roller conveyor platform 6, and the axis of the conveying roller in the roller conveyor platform 6 is parallel to the extension and retraction direction of the push cylinder 71. A push assembly 7 is provided on one side of the conveyor platform 6 for pushing the sleeper mold 11 on the conveyor platform 6 onto the vibrating table 4.

[0035] Referring to Figures 1 and 3, the pushing assembly 7 includes a placement platform 73, on which a pushing cylinder 71 is fixedly connected. A push plate 72 is fixedly connected to the output shaft of the pushing cylinder 71. The pushing cylinder 71 is used to push the sleeper mold 11 on the conveyor table 6 onto the vibrating table 4. At the same time, in order to reduce the occurrence of the sleeper mold 11 detaching from the conveyor table 6, a baffle 10 for blocking the sleeper mold 11 is fixedly connected to the conveying end of the conveyor table 6.

[0036] The vibrating table 4 is equipped with a feeding mechanism 5 for adding polyurethane concrete mixture to the sleeper mold 11. The feeding mechanism 5 includes a support frame 51, which is mounted on the ground. A feeding plate 52 is slidably connected to the support frame 51, and the feeding plate 52 is rectangular. An output pipe 53 is fixed and connected to the mixing tank 3. A material control valve 531 is installed on the output pipe 53. The end of the output pipe 53 away from the mixing tank 3 is fixedly connected to the feeding plate 52, and the opening of the output pipe 53 faces the vibrating table 4. The feeding plate 52 is equipped with a drive assembly 54 for sliding the feeding plate 52 along the length of the support frame 51.

[0037] The drive assembly 54 includes multiple pairs of pulleys 541 disposed at the lower end of the feed plate 52. In this embodiment, four pulleys 541 are provided and are respectively installed at the four corners below the feed plate 52. A common drive motor 542 is provided between the same pair of pulleys 541. The output shaft of the drive motor 542 is connected to the shaft of the pulley 541. The drive motor 542 is fixedly connected to the lower end of the feed plate 52, and the pulleys 541 are slidably connected to the support frame 51.

[0038] When the sleeper mold 11 is placed on the vibrating table 4, the drive motor 542 can be started. The drive motor 542 can drive the pulley 541 to slide on the support frame 51, thereby causing the feed plate 52 to drive the output pipe 53 to move along the length of the support frame 51, and thus evenly distribute the material in the sleeper mold 11.
