Description

Technical Field

[0001] This invention relates to the field of sleeper production equipment technology, specifically to a sleeper demolding and transfer device in a concrete sleeper production line. Background Technology

[0002] The current production and processing of concrete railway sleepers involves mold forming. A release agent is sprayed into the mold beforehand, and the pre-arranged steel reinforcement components are placed inside. Then, the proportioned concrete is poured into the mold, vibrated to compact it and eliminate air bubbles, and after solidification, the concrete is removed by flipping the mold. The sleeper surface is smooth due to the coating agent, preventing the concrete from sticking to the mold surface and facilitating sleeper removal. After removal from the mold, most sleepers are transported one by one via roller conveyor, then stacked in an orderly manner by hoisting equipment. Forklifts then store the sleepers in a curing area. After a period of curing, they are ready for sale. This method of handling demolded sleepers is extremely cumbersome, requiring the combined use of roller conveyors and hoisting equipment. The hoisting equipment, along with steel cables, lifts and stacks the sleepers one by one.

[0003] To address the aforementioned issues, Chinese Patent CN202210322905.5 discloses a sleeper demolding and transfer device for a concrete sleeper production line, comprising a pipeline conveyor, a first lifting device, and a material handling and arranging device. The first lifting device is installed at the gap between the rollers of the roller conveyor, and the material handling and arranging device is located on the side of the roller conveyor. The first lifting device lifts the sleepers transported on the roller conveyor, detaching them from the roller conveyor. The material handling and arranging device then removes and arranges the sleepers from the first lifting device. This device can remove and arrange the sleepers from the roller conveyor, allowing forklifts to directly transport them to the sleeper curing area for stacking, eliminating the cumbersome method of using hoisting equipment and steel ropes to lift and stack the sleepers one by one.

[0004] Although the aforementioned existing technology achieves the conveying and arrangement of sleepers by allowing them to slide down the loading platform on their own, and uses springs in conjunction with buffer plates for cushioning, the springs behind the first sleeper will deform under pressure when they come into contact with the buffer plate. As subsequent sleepers slide down in sequence, the deformation of the springs will become increasingly greater, resulting in poor cushioning. Furthermore, subsequent sleepers are mostly subjected to rigid impacts, and adjacent sleepers will also collide with each other during their sequential arrangement. In addition, the aforementioned existing technology uses sleepers to slide autonomously on an inclined loading platform, and some concrete residue will remain on the surface of the loading platform during use, which will cause the sleepers to deviate and get stuck during sliding, resulting in poor actual performance.

[0005] Therefore, we propose a sleeper demolding and transfer device for concrete sleeper production lines. Summary of the Invention

[0013] In some embodiments, the cleaning unit includes a main pipe disposed at the bottom of the loading platform, a plurality of branch pipes disposed on the main pipe, the main pipe being connected to a connecting pipe via a conduit, the plurality of branch pipes being arranged in a linear array on the surface of the loading platform, and a plurality of rollers being rotatably disposed on the surface of the loading platform, the height of the branch pipes being less than the height of the rollers.

[0014] In some embodiments, the branch pipe is arranged along the axial direction of the roller on the loading platform, the middle part of the branch pipe is connected to the main pipe and both ends are open, and the diameter of the branch pipe gradually decreases from the middle to the ends.

[0015] In some embodiments, a rotating seat is provided at both ends of the material carrier platform.

[0016] The present invention has at least the following beneficial effects:

[0017] 1. Multiple telescopic contact units corresponding to the sleeper positions can abut against the sleeper when it slides down, thereby pressing against the pneumatic buffer unit to buffer the sleeper when it slides down. Each sleeper triggers an independent U-shaped rod to move, pushing the top rod to squeeze the pneumatic buffer unit. The impact energy is consumed by depressurizing through the air cylinder, avoiding rigid collisions that could damage the sleeper.

[0018] 2. The connecting frame at the front end of the pneumatic buffer unit includes multiple layers of pressure plates, pressure plates one, two, and three, whose height is controlled by a cylinder. When different sleepers slide down, the cylinder automatically adjusts the height of the pressure plates to align with the corresponding top rod, ensuring that each sleeper can match the buffer path and solving the problem of insufficient adaptability of a single buffer unit.

[0019] 3. When the pneumatic buffer unit is depressurized, the gas discharged is introduced into the cleaning unit through the Y-shaped connecting pipe. The air jet removes residual concrete debris, preventing the debris from obstructing the sleeper's sliding, and reducing the energy consumption of additional cleaning equipment.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0034] Example 1: Please refer to Figures 1-4 This invention provides a technical solution: a sleeper demolding and transfer device in a concrete sleeper production line, including a roller conveyor 1 and a lifting device disposed inside the roller conveyor 1. The lifting device includes a hydraulic cylinder and a lifting frame disposed at the output end of the hydraulic cylinder. When the roller conveyor 1 transports the demolded sleeper to the top of the lifting device, the hydraulic cylinder is activated to drive the lifting frame to move upward and lift the sleeper so that it is separated from the roller conveyor 1. The device also includes a material picking device, which includes a hydraulic cylinder, a material support platform, a push plate and a spring. The purpose is to transfer the sleeper on the lifting frame. The lifting device and the material picking device are existing technologies, and their specific structures and usage methods have been described in detail in the prior art, and will not be repeated here.

[0035] A base 2 is provided on one side of the roller conveyor 1, and a loading platform 3 is provided on the base 2. A lifting device lifts the sleeper rail on the roller conveyor 1, and a material handling device transfers the sleeper rail to the loading platform 3. The loading platform 3 is inclined, and a side plate 4 is fixedly provided on the rear side of the loading platform 3. When the sleeper rail moves onto the loading platform 3, due to its inclined shape, the sleeper rail will slide on the loading platform 3 until it abuts against the side plate 4, completing the transfer of one sleeper rail from the roller conveyor 1 to the loading platform 3. Multiple [unclear text - possibly related to a specific device or mechanism] are provided on both sides of the loading platform 3. The device includes a telescopic contact unit 5 and a pneumatic buffer unit 6 on one side of the bottom of the loading platform 3. The telescopic contact unit 5 moves and abuts against the pneumatic buffer unit 6. The loading platform 3 can support multiple rail sleepers, and the collected rail sleepers are then transferred using a forklift. However, as the rail sleepers slide down the loading platform 3, their significant weight generates considerable kinetic energy. If the rail sleepers directly impact the edge plate 4, it could cause damage. Therefore, this device incorporates telescopic contact units on both sides of the loading platform 3. 5. When the first sleeper slides down, the telescopic contact unit 5 closest to the rail plate 4 extends. At this time, the first sleeper slides down and can abut against the telescopic contact unit 5 and drive it to move. When the telescopic contact unit 5 moves, it can contact the pneumatic buffer unit 6 and buffer the impact generated by the movement of the sleeper by deflating the air. Similarly, when a sleeper falls, its corresponding telescopic contact unit 5 extends and cooperates with the sleeper. A cleaning unit 7 is provided on the loading platform 3. The cleaning unit 7 is connected to the pneumatic buffer unit 6. An air pump is also provided on the base 2. The air pump is existing technology and is not shown in the figure. When the pneumatic buffer unit 6 deflates, the gas it discharges will be sprayed out through the cleaning unit 7. The cleaning unit 7 is set on the surface of the loading platform 3, and the surface of the loading platform 3 can be cleaned by air jet cleaning to prevent concrete residue from remaining on the loading platform 3 and affecting the sliding of the sleeper. The air pump can inflate the pneumatic buffer unit 6 to restore it to its initial state for the next buffering.

[0036] After the sleeper rail is demolded, the roller conveyor 1 transports the sleeper rail to the lifting device, which lifts the sleeper rail. Then, the material handling device transfers the sleeper rail to the loading platform 3. The sleeper rail slides down the loading platform 3 until it abuts the edge plate 4. When the sleeper rail slides down, the corresponding telescopic contact unit 5 extends to contact the sleeper rail and moves with it. When the telescopic contact unit 5 moves, it can drive the pneumatic buffer unit 6 to release air, thereby buffering the impact of the sleeper rail's movement through air release. The gas released is transported to the cleaning unit 7 to clean the loading platform 3, eliminating the need for a separate cleaning mechanism and achieving energy-saving effects.

[0037] Example 2: Please refer to Figures 5-7This invention provides a technical solution: a sleeper demolding and transfer device in a concrete sleeper production line. The bottom of the loading platform 3 is fixedly equipped with slide rails 8 on both sides. Multiple slide rods 9 are slidably arranged inside the slide rails 8. The slide rods 9 are T-shaped, and the slide rails 8 also have T-shaped grooves to cooperate with them. A telescopic contact unit 5 includes multiple U-shaped rods 51 located at the bottom of the loading platform 3. The U-shaped rods 51 are fixedly connected to the bottom of the slide rods 9, allowing the U-shaped rods 51 to move along the slide rails 8. Electromagnetic telescopic blocks 52 are provided at both ends of the U-shaped rods 51. These blocks can extend and contact the sleeper rails as they move. A top rod 53 is fixedly arranged in the middle of the U-shaped rod 51. When the U-shaped rod 51 moves, it drives the top rod 53 to move, and the top rod 53, when moving, compresses the pneumatic buffer unit 6.

[0038] The U-shaped rod 51 has a through hole 54 for the top rods 53 on other U-shaped rods 51 to pass through. Since all U-shaped rods 51 are at the same height and each U-shaped rod 51 is equipped with a top rod 53, when the rear U-shaped rod 51 moves the top rod 53, the top rod 53 will abut against the front U-shaped rod 51 to make it move. This will cause the front U-shaped rod 51 to block the rear U-shaped rod 51. Therefore, the front U-shaped rod 51 has a through hole 54 to allow the top rods 53 on the rear of all U-shaped rods 51 to pass through, so that each U-shaped rod 51 can move and drive the top rod 53 to abut against the pneumatic buffer unit 6.

[0039] The electromagnetic telescopic block 52 includes a fixed sleeve 521 fixedly installed at the end of the U-shaped rod 51. An extension plate 522 is slidably installed inside the fixed sleeve 521. A support spring 523 is installed inside the fixed sleeve 521. The two ends of the support spring 523 are connected to the extension plate 522 and the fixed sleeve 521 respectively. A magnetic plate 524 is installed at the bottom of the extension plate 522. An electromagnet is installed inside the fixed sleeve 521. When the electromagnet is energized, it repels the magnetic plate 524 and drives the magnetic plate 524 to move. The magnetic plate 524 drives the extension plate 522 to move, so that the extension plate 522 extends out of the fixed sleeve 521. Thus, when the sleeper rail slides along the loading platform 3, the two ends of the sleeper rail will abut against the extension plate 522, thereby driving the U-shaped rod 51 to move. The U-shaped rod 51 drives the top rod 53 to abut against the pneumatic buffer unit 6 for buffering.

[0040] Example 3: Please refer to Figure 10This invention provides a technical solution: a sleeper demolding and transfer device in a concrete sleeper production line. The pneumatic buffer unit 6 includes a support rod mounted on a base 2, with an air cylinder 61 fixedly mounted on the support rod. A piston 62 is slidably mounted inside the air cylinder 61. A moving rod 63 is mounted on the piston 62, penetrating the air cylinder 61. A push rod 53 can drive the moving rod 63 to move, thereby driving the piston 62 to move. When the piston 62 moves, it discharges the gas from the air cylinder 61. A connecting pipe 64 is located at the rear of the air cylinder 61. The connecting pipe 64 is Y-shaped, and its two ends are respectively connected to an air pump and a cleaning unit 7. Solenoid valves are installed in both ends of the connecting pipe 64. Do not control the opening and closing of the two ports of the connecting pipe 64. When the sleeper slides down, it drives the top rod 53 to move. When the top rod 53 abuts against the pneumatic buffer unit 6, the connecting pipe 64 is connected to the cleaning unit 7. Then the gas in the air cylinder 61 is squeezed into the cleaning unit 7. After the sleeper slides down, the air pump is connected to the connecting pipe 64 to fill the air cylinder 61 with air, so that it returns to its initial state, which is convenient for the next buffer operation. A connecting frame 65 is movably set on the plate 4. The connecting frame 65 is located between the top rod 53 and the moving rod 63. That is, when the top rod 53 moves, it first abuts against the connecting frame 65 and drives the connecting frame 65 to move. Then the connecting frame 65 drives the moving rod 63 to move.

[0041] Example 4: Please refer to Figures 8-9 The present invention provides a technical solution: a sleeper demolding and transfer device in a concrete sleeper production line, wherein a cylinder 10 is fixedly installed on a plate 4, and an installation plate 11 is provided at the output end of the cylinder 10. A guide groove 12 is provided at the bottom of the installation plate 11, and a guide block 13 is slidably arranged in the guide groove 12. A connecting frame 65 is fixedly connected to the guide block 13, so that the connecting frame 65 can move along the guide groove 12. When the top rod 53 drives the connecting frame 65 to move, the connecting frame 65 moves along the guide groove 12, and when the cylinder 10 extends and retracts, it can drive the installation plate 11 to move, thereby driving the connecting frame 65 to move up and down.

[0042] The connecting frame 65 includes a pressure plate 651 fixedly connected to the guide block 13. Connecting blocks 652 are fixedly installed on both sides of the bottom of the pressure plate 651. Fixing rods 653 are fixedly installed on the side walls of the two connecting blocks 652. A pressure plate 654 is installed at the end of the fixing rod 653. A pressure plate 655 is fixedly installed on the side wall of the pressure plate 654. The pressure plate 651 is located on the upper side of the pressure plate 654, and the pressure plate 654 is located on the upper side of the pressure plate 655. A bracket 656 is fixedly installed on the connecting block 652. When any one of the pressure plates moves, it can drive the bracket 656 to move. The bracket 656 abuts against the moving rod 63 to make it move.

[0043] In this embodiment, three U-shaped rods 51 are provided, and corresponding pressure plates 651, 654, and 655 are provided. The number of pressure plates is always consistent with the number of U-shaped rods 51, and the number can be set according to actual needs. Each pressure plate corresponds to one U-shaped rod 51, and the pressure plates 651, 654, and 655 are not the same in height. In this way, when the cylinder 10 starts and drives the connecting frame 65 to move, it can drive each pressure plate to correspond to the height of the push rod 53, so that when the push rod 53 moves, it can only drive the corresponding height of the pressure plate. When the first sleeper rail slides down and drives its corresponding U-shaped rod 51 to move, the top rod 53 on the U-shaped rod 51 abuts against the first pressure plate 651 to make it move. When the next sleeper rail drives its corresponding U-shaped rod 51 to move, the cylinder 10 will drive the second pressure plate 654 to align with the top rod 53 at the same height. Then, the top rod 53 on the U-shaped rod 51 can drive the second pressure plate 654 to move. With this setting, each sleeper rail can be buffered by the pneumatic buffer unit 6 when it slides down, avoiding the problem of rigid impact caused by a single buffer in the prior art.

[0044] After the sleepers are transferred to the loading platform 3, the movement of each sleeper will cause the corresponding extension plate 522 to move. Therefore, after the loading platform 3 is full of sleepers, there is a gap between adjacent sleepers. This way, the sleepers will not collide with each other during subsequent transfer, reducing damage.

[0045] Example 5: Please refer to Figure 12 This invention provides a technical solution: a sleeper demolding and transfer device in a concrete sleeper production line. The cleaning unit 7 includes a main pipe 71 located at the bottom of the loading platform 3. Multiple branch pipes 72 are installed on the main pipe 71. The main pipe 71 is connected to a connecting pipe 64 through a pipe. The multiple branch pipes 72 are arranged in a linear array on the surface of the loading platform 3. When the gas in the pneumatic buffer unit 6 is compressed and transported into the main pipe 71, the gas is sprayed out through each branch pipe 72, thereby cleaning the surface of the loading platform 3. In order to ensure the airflow speed, the pipe diameter of the main pipe 71 and the branch pipes 72 should be much smaller than the pipe diameter of the connecting pipe 64. In specific implementation, it can be adjusted according to the requirements. Multiple rollers are rotatably installed on the surface of the loading platform 3. The height of the branch pipes 72 is less than the height of the rollers. The rollers enable the sleeper to move more smoothly. Since the height of the branch pipes 72 is less than the height of the rollers, the branch pipes 72 will not affect the movement of the sleeper on the loading platform 3.

[0046] Branch pipe 72 is arranged along the axial direction of the roller on the material carrier 3. The middle part of branch pipe 72 is connected to the main pipe 71 and both ends are open. The diameter of branch pipe 72 gradually decreases from the middle to the end, which can increase the jet speed of airflow and make its cleaning effect better.

[0047] Example 6: Please refer to Figure 11The present invention provides a technical solution: a sleeper demolding and transfer device in a concrete sleeper production line, wherein a rotating seat 14 is provided at both ends of a loading platform 3, a support rod 15 is rotatably connected to the rotating seat 14 at one end of the loading platform 3, the bottom end of the support rod 15 is connected to the base 2, and the rotating seat 14 is slidably disposed at the bottom of the loading platform 3, a support frame 16 is rotatably connected to the rotating seat 14 at the other end of the loading platform 3, a sleeve 17 is fixedly disposed at the bottom end of the support frame 16, a threaded sleeve 18 is rotatably disposed at the bottom end of the sleeve 17, a screw 19 is fixedly disposed on the base 2, and the threaded sleeve 18 is threadedly connected to the screw 19.

[0048] In actual production, the weight of different batches of sleepers varies. Due to the large weight of the sleepers, the inclination angle of the loading platform 3 directly affects the kinetic energy impact of their descent. When the inclination angle is too large, the impact is too great, but the descent is smoother. When the inclination angle is too small, the impact force is small, but the descent may be obstructed. Therefore, this application sets the loading platform 3 as an adjustable structure, which can finely adjust the inclination angle of the loading platform 3 according to different sleepers, thereby meeting the actual use requirements. During adjustment, rotating the threaded sleeve 18 can drive the sleeve 17 to rise, thereby driving the loading platform 3 to move upward.
