Description

Technical Field

[0001] This utility model belongs to the technical field of railway sleeper production and conveying equipment, specifically relating to a railway sleeper rough surface treatment and conveying device. Background Technology

[0002] Railway sleepers are crucial foundational components in railway track structures, bearing the rails and transmitting loads. The production of concrete sleepers involves multiple processes, including demolding and curing, installation of embedded parts, and surface roughening. Surface roughening treatments (such as waterjet roughening, sandblasting, or chemical etching) significantly improve the bonding strength between the sleeper and ballast. The conveying device, as the core carrier connecting these processes, is responsible for accurately transporting the sleepers to the surface roughening equipment station. Currently, mainstream production lines use roller conveyors to receive the demolded sleepers, with the roller assembly driven by a motor to achieve axial transport. However, due to demolding and hoisting errors from the previous process, cumulative tolerances in roller installation, and differences in surface condition, sleepers are prone to positional and angular deviations during transport, directly affecting the uniformity of subsequent surface roughening and the achievement rate of bonding strength standards.

[0003] The core technical problem with existing conveying devices lies in their inability to dynamically correct sleeper attitude deviations. Specifically, when a sleeper enters the rough surface treatment station in a non-centered or skewed state, one edge may collide with the positioning baffle of the treatment equipment, causing damage to the concrete edges; or the attitude deviation may cause inaccurate coordinate positioning of the robot grasping system—the robotic arm may miss or become unstable when grasping the sleeper according to the preset trajectory because the actual position of the sleeper deviates from the theoretical coordinates, triggering an emergency stop; even if the sleeper is successfully grasped, after being placed into the surface treatment equipment, the angle at which the skewed sleeper receives water jet or abrasive impact is uneven, and some areas are not treated sufficiently, directly reducing the service life of the sleeper. Utility Model Content

[0004] The purpose of this invention is to provide a sleeper rough surface treatment and conveying device to solve the problem of insufficient accuracy in subsequent rough surface treatment processes caused by positional deviation of the sleeper during the conveying process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A sleeper roughening surface treatment conveying device, comprising: A sleeper conveyor, wherein an installation box is provided on the outer periphery of the sleeper conveyor, the installation box having an inlet and an outlet along the axial direction of the sleeper conveyor, and a correction mechanism is provided inside the box; The correction mechanism includes two symmetrically arranged rotating frames in a figure-eight configuration. Multiple evenly distributed guide rollers are rotatably mounted on opposite sides of each rotating frame, all arranged vertically. Fixed shafts are symmetrically fixed to the top and bottom surfaces of the rotating frames near the inlet. A fixed frame, U-shaped, is rotatably fitted around the outer periphery of both fixed shafts. A connecting arm is fixed to the outer wall of the fixed frame, and a stabilization control component is fixed to the end of the connecting arm away from the fixed frame. A positioning rod is fixed to the top surface of the rotating frames near the outlet, and a vertically penetrating arc-shaped track groove is formed on the side of the positioning rod away from the rotating frames. A sliding shaft slides within the track groove, and the bottom end of the sliding shaft is mounted on the stabilization control component. An elastic reset component is provided between the stabilization control component and the rotating frames. A spacing adjustment component is provided on the bottom surface inside the mounting box, and the bottom ends of the two stability control components are both mounted on the spacing adjustment component.

[0006] Preferably, the two rotating frames are arranged in a zigzag shape on the side near the entrance, and their openings are outward-pointing.

[0007] Preferably, the elastic reset component includes a compression spring whose end face is fixedly mounted on the stabilization control component, and a ball head seat is fixedly mounted on the end face of the compression spring away from the stabilization control component, the front end of the ball head seat movably abutting against the outer wall of the rotating frame.

[0008] Preferably, the stabilization control component includes a support arm, with the two sides of the outer side wall of the support arm being fixedly connected to a connecting arm and a compression spring, respectively. The bottom surface of the sliding shaft is rotatably mounted on the top surface of the support arm, and adapter frames are symmetrically fixed on both sides of the bottom surface of the support arm. The bottom surfaces of multiple adapter frames are all mounted on the spacing adjustment component.

[0009] Preferably, the spacing adjustment component includes a dual-axis power unit. The bottom center of the mounting box has an installation opening. The dual-axis power unit is installed in the installation opening. Both output shafts at both ends of the power unit are fixedly equipped with linkage shafts. The two linkage shafts are arranged in a direction perpendicular to the axis of the sleeper conveyor. A ball screw is fixedly installed at one end of each linkage shaft. The external threads of the two ball screws are symmetrically arranged. A moving block is threaded around the outer periphery of each ball screw. Guide components are provided on both sides of the moving block.

[0010] Preferably, the guide assembly includes a guide rod arranged parallel to the ball screw, the bottom surface of the guide rod is fixedly mounted on the bottom surface of the mounting box, and two limiting sliders are slidably sleeved on its outer periphery. The top surfaces of the two limiting sliders are fixedly connected to the corresponding transfer frame. The two limiting sliders on the same side arranged along the axis of the sleeper conveyor are fixedly connected to the moving block on their opposite sides.

[0011] Compared with the prior art, the beneficial effects of this utility model are: (1) Two rotating frames are symmetrically arranged in a figure-eight shape. The side near the entrance is open in a figure-eight shape, which can guide sleepers with different degrees of deviation into the correction area. The vertical guide rollers on the rotating frames can reduce friction with the sleepers and avoid damage to the sleeper surface during transportation. At the same time, the rotation of the rotating frames around the fixed axis and the clamping correction force generated by the elastic reset component can dynamically correct the positional deviation and angle deflection of the sleepers, ensuring that the sleepers are accurately transported along the preset trajectory, avoiding collision with the positioning baffle of the subsequent rough surface treatment equipment, and reducing the situation of concrete edge damage.

[0012] (2) The external threads of two ball screws are symmetrically arranged to make the outer peripheral moving blocks relatively close or relatively far away in the direction perpendicular to the axis of the sleeper conveyor. At the same time, under the limit guidance of the guide component, the two stable control components move synchronously, thereby adjusting the distance between the two rotating frames to adapt to the conveying requirements of sleepers of different specifications, ensuring that the correction mechanism can play a stable and effective clamping and correction role for sleepers of different sizes, and improving the versatility and adaptability of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Example 1:

[0016] Please see Figures 1-4 As shown, a sleeper roughening surface treatment conveying device includes: The sleeper conveyor 1 has an installation box 2 on its outer periphery. The installation box 2 has an inlet and an outlet along the axis of the sleeper conveyor 1, and a correction mechanism is provided inside it. The correction mechanism includes two symmetrically arranged rotating frames 3 in a figure-eight configuration. Multiple evenly distributed guide rollers 4 are rotatably mounted on opposite sides of each rotating frame 3, all arranged vertically. Fixed shafts 6 are symmetrically fixed to the top and bottom surfaces of the rotating frame 3 near the inlet. A fixed frame 5, U-shaped, is rotatably sleeved around the outer periphery of the two fixed shafts 6. A connecting arm 7 is fixed to the outer wall of the fixed frame 5. A stabilization control component is fixed to the end of the connecting arm 7 away from the fixed frame 5. A positioning rod 8 is fixed to the top surface of the rotating frame 3 near the outlet. A vertically penetrating arc-shaped track groove 9 is formed on the side of the positioning rod 8 away from the rotating frame 3. A sliding shaft 10 is slidably arranged within the track groove 9. The bottom end of the sliding shaft 10 is mounted on the stabilization control component. An elastic reset component is provided between the stabilization control component and the rotating frame 3. The bottom surface inside the mounting box 2 is equipped with a spacing adjustment component, and the bottom ends of the two stabilization control components are both mounted on the spacing adjustment component.

[0017] Depend on Figure 2 and Figure 3 It is known that the elastic reset component includes a compression spring 11 with its end face fixedly mounted on the stabilization control component. A ball head seat 12 is fixedly mounted on the end face of the compression spring 11 away from the stabilization control component. The front end of the ball head seat 12 movably abuts against the outer wall of the rotating frame 3.

[0018] As can be seen from the above, the sleepers are conveyed by the sleeper conveyor 1 and enter the interior of the mounting box 2 through the inlet. When the sleeper comes into contact with the two symmetrically arranged rotating frames 3, the side of the rotating frame 3 near the inlet is open in an outward V-shape (which can guide sleepers with different degrees of deviation into the correction area). The sleeper will first come into contact with the vertical guide roller 4 mounted on the opposite side of the rotating frame 3 (the guide roller 4 can reduce friction with the sleeper and avoid damage to the sleeper surface during conveying). As the sleeper continues to be conveyed, it will push the rotating frame 3 to rotate around the fixed frame 5 with the fixed shaft 6 as the fulcrum. At this time, the arc-shaped track groove 9 on the positioning rod 8 near the outlet side of the rotating frame 3 will slide relative to the sliding shaft 10 (the sliding shaft 10 is mounted on the stabilization control component to limit the rotation trajectory of the rotating frame 3). The outer wall of frame 3 will compress the ball head seat 12 in the elastic reset assembly, causing the ball head seat 12 to drive the compression spring 11 to compress. The reaction force of the compression spring 11 acts on the rotating frame 3 through the ball head seat 12, and together with the guide roller 4, it forms a clamping and correcting force on the sleeper, gradually guiding the offset sleeper to the correct position. The ball head structure of the ball head seat 12 can adapt to the angle change of the outer wall of the rotating frame 3 when it rotates around the fixed axis 6 during the correction of the sleeper, ensuring that the rotating frame 3 always maintains stable contact with the ball head seat 12 during the rotation process, avoiding contact failure or jamming caused by the change of the angle of the rotating frame. After the sleeper passes through the rotating frame 3, the compression spring 11 resets, pushing the ball head seat 12 to drive the rotating frame 3 to rotate in the opposite direction until the sliding shaft 10 resets in the arc-shaped track groove 9, so that the rotating frame 3 returns to its initial position.

[0019] Specifically, regarding the above, please refer to... Figure 2 and Figure 3 As shown, the two rotating frames 3 are both arranged in a zigzag shape on the side near the entrance, and their openings are outward-pointing.

[0020] As can be seen from the above, the zigzag arrangement of the two rotating frames 3 near the entrance and their outward V-shaped openings work together to form a guide structure with a large and gradually narrowing area at the entrance. The outward V-shaped opening can accommodate sleepers with different degrees of offset and angular deflection, while the zigzag design makes this guiding process smoother, avoiding severe impact on the sleepers. When the sleeper enters from the entrance of the mounting box 2 and is conveyed on the sleeper conveyor 1, it will first contact the guide roller 4 on the opposite side of the rotating frame 3. Under the action of the conveying force, the outward V-shaped rotating frame 3 will gradually guide the offset sleeper towards the center. At the same time, the rotation of the guide roller 4 reduces the friction between it and the sleeper, preventing the sleeper surface from being scratched. Through this structural cooperation, the positional offset and angular deflection of the sleeper can be gradually corrected during the sleeper conveying process, ensuring that the sleeper moves towards the exit direction in the correct posture. This provides a precisely positioned sleeper for the subsequent rough surface treatment process, solving the problem of insufficient processing accuracy caused by sleeper offset in the existing technology.

[0021] Specifically, regarding the above, please refer to... Figure 4 As shown, the stabilization control assembly includes a support arm 13. The two sides of the outer wall of the support arm 13 are fixedly connected to the connecting arm 7 and the compression spring 11, respectively. The bottom surface of the sliding shaft 10 is rotatably mounted on the top surface of the support arm 13. Adapter frames 14 are symmetrically fixed on both sides of the bottom surface of the support arm 13. The bottom surfaces of multiple adapter frames 14 are all mounted on the spacing adjustment assembly.

[0022] As can be seen from the above, the support arm 13, as the core load-bearing structure, has one side of its outer wall connected to the fixed frame 5 through the connecting arm 7, providing stable support for the rotation of the rotating frame, and the other side is fixedly connected to the compression spring 11, so that the force of the elastic reset component can be stably applied to the rotating frame. The bottom surface of the sliding shaft 10 is rotatably mounted on the top surface of the support arm 13, which not only ensures the stability of the sliding shaft 10 when sliding in the arc-shaped track groove 9 of the rotating frame, but also reduces the frictional resistance during the sliding process through the rotatable connection, ensuring that the rotating frame rotates smoothly. The adapter frames 14 on both sides of the bottom surface of the support arm 13 connect the support arm 13 to the spacing adjustment component. This allows the spacing adjustment component to move the adapter frames 14, thereby moving the support arm 13 and its connected components such as the connecting arm 7, the compression spring 11, and the sliding shaft 10 synchronously. This achieves the adjustment of the relative positions of the two stable control components, and ultimately completes the adjustment of the spacing between the two rotating frames. Example 2:

[0023] refer to Figure 4 As shown, the spacing adjustment assembly includes a dual-axis power unit 17. The bottom center of the mounting box 2 has an installation port, and the dual-axis power unit 17 is installed in the installation port. Both output shafts at both ends of the dual-axis power unit 17 are fixedly equipped with linkage shafts 18. The two linkage shafts 18 are arranged in a direction perpendicular to the axis of the sleeper conveyor 1. A ball screw 19 is fixedly installed at one end of each linkage shaft 18. The external threads of the two ball screws 19 are symmetrically arranged, and a moving block 20 is threadedly sleeved on the outer periphery of each ball screw 19. Guide components are provided on both sides of the moving block 20.

[0024] As can be seen from the above, the dual-axis power unit 17 includes, but is not limited to, any device that can provide power, such as a dual-axis stepper motor. The rotation direction of the two shafts is the same, which is existing technology and will not be described in detail here. After the dual-axis power unit 17 is started, its two output shafts drive the linkage shaft 18 to rotate (the linkage shaft 18 is set along the direction perpendicular to the axis of the sleeper conveyor 1), which in turn drives the ball screw 19 fixed at one end of the linkage shaft 18 to rotate synchronously. Since the external threads of the two ball screws 19 are symmetrically arranged, the moving block 20, which is threaded around its outer periphery, will move relatively closer or oppositely away from the screw axis under the action of the rotating ball screw 19. The guide components on both sides of the moving block 20 limit and guide its movement direction to ensure smooth movement. The movement of the moving block 20 will drive the stabilization control component connected to it to move synchronously, thereby adjusting the relative distance between the two stabilization control components, and finally realizing the adjustment of the distance between the two rotating frames 3 to adapt to the conveying and correction needs of sleepers of different specifications. This solves the problem that the existing device is difficult to adapt to various sleeper sizes and improves the versatility and practicality of the device.

[0025] Preferred, Reference Figure 4 As shown, the guide assembly includes a guide rod 16 arranged parallel to the ball screw 19. The bottom surface of the guide rod 16 is fixedly set on the bottom surface of the mounting box 2. Two limit sliders 15 are slidably sleeved on its outer periphery. The top surfaces of the two limit sliders 15 are fixedly connected to the corresponding adapter frame 14. The two limit sliders 15 arranged on the same side along the axis of the sleeper conveyor 1 are fixedly connected to the moving block 20 on their opposite sides.

[0026] As can be seen from the above, when the moving block 20 moves under the action of the ball screw 19, it will drive the limiting slider 15 to slide along the guide rod 16. The guide rod 16 precisely limits the movement direction of the limiting slider 15 to prevent it from deviating or shaking, ensuring the stability and accuracy of the moving block 20 and the connected adapter frame 14 and other structures. This ensures that the spacing adjustment of the two rotating frames 3 is accurate and reliable, so as to stably adapt to the conveying and correction requirements of sleepers of different specifications and improve the stability and accuracy of the device in the spacing adjustment process.
