TECHNICAL FIELD
[0001] The utility model relates to road engineering equipment design field especially, relates to an intelligent continuous compaction device for railway subgrade. BACKGROUND
[0002] With the rapid development of railway construction, the quality requirement of railway subgrade is increasingly improved. The compaction operation of railway subgrade is the key link to ensure the stability, bearing capacity and durability of subgrade. An intelligent continuous compaction device for railway subgrade emerges as the times require, which aims to accurately carry out continuous compaction operation on subgrade through intelligent control system and efficient compaction mechanism to meet the strict quality standards of subgrade compaction degree, flatness and the like of modern railway engineering. In the whole compaction device, the compaction roller is directly contacted with the subgrade and applies pressure, and the working state directly affects the compaction effect and engineering quality.
[0003] Some existing railway subgrade compaction devices mainly adopt simple mechanical structure, which is usually powered by engine, and the power is transmitted to the compaction roller through transmission device to make the roller rotate and roll on the subgrade. In terms of technical principle, the subgrade material is compacted mainly by the weight of the roller and the pressure generated by the torque transmitted by the engine, and the parameter monitoring in the compaction process mainly uses basic sensors, and these sensors are usually simply fixed at specific parts of the device, lacking depth integration and intelligent control with the whole compaction operation process.
[0004] The traditional intelligent continuous compaction device for railway subgrade lacks cleaning mechanism, and these attachments will cause slipping or local poor contact between the roller and the subgrade. This poor contact makes the compaction pressure unable to be uniformly transmitted, seriously affecting the compaction quality and density of the subgrade, and it is difficult to meet the high-standard construction demand of modern railway subgrade. Therefore, an intelligent continuous compaction device for railway subgrade is proposed to solve the above problems. UTILITY MODEL CONTENTS

[0031] When compaction vehicle 1 compacts road surface, roller 3 rolls and compacts road surface, impurity material on road surface adheres to the surface of roller 3, at this time, impurities on the surface of roller 3 are removed to the inside of drawer 13 by scraper 6, effectively remove the adhering material on compaction roller, guarantee good contact between roller 3 and subgrade, when compaction vehicle 1 stops compaction work on road surface, pull handle 15 to move outward, at this time, clamping column 12 is extruded by the movement of drawer 13, clamping column 12 is downwardly deflected with fixed column 11 as the axis, at this time, spring 10 is extruded and deformed, provide certain support force and initial position positioning effect for clamping column 12, until drawer 13 is separated from cleaning box 7, spring 10 loses extrusion and resets, finally, impurities in the inside of drawer 13 are cleaned, avoid secondary pollution or affect the continuous progress of cleaning work caused by impurity leakage.
[0032] With reference to Figure 4The telescopic mechanism comprises a second rotating roller 16, which provides a stable connection basis for other components connected thereto, and ensures the reliability and accuracy of the components during relative movement. The side wall of the second rotating roller 16 is fixedly connected to the side wall of the compactor 1. The side wall of the second rotating roller 16 is rotatably connected to a first fixing block 17. The side wall of the first fixing block 17 is fixedly connected to a push-pull rod 20 ， The output end of the push-pull rod 20 is fixedly connected to a connecting column 21. The end of the connecting column 21 away from the push-pull rod 20 is fixedly connected to a second fixing block 23. The second fixing block 23 is rotatably connected to the side wall of the first rotating roller 5. The side wall of the second rotating roller 16 is fixedly connected to a first fixing frame 18, which provides an auxiliary support point for the installation and positioning of other related components, thereby helping to improve the overall strength and rigidity of the telescopic mechanism. The first fixing block 17 is arranged inside the first fixing frame 18. One end of the spring 10 is fixedly connected to the inside of the cleaning box 7. The other end of the spring 10 is fixedly connected to the side wall of the clamping column 12. The side wall of the protective fence 4 is fixedly connected to a second fixing frame 22, which prevents the protective fence 4 from being damaged or deformed due to external forces, thereby ensuring the reliability of the connection and cooperative work between the telescopic mechanism and the cleaning mechanism. The second fixing frame 22 is fixedly connected to the side wall of the first rotating roller 5. The side wall of the compactor 1 is fixedly connected to a connecting frame 24. The inside of the connecting frame 24 is fixedly connected to a rotating column 25. The side wall of the protective frame 19 is fixedly connected to a connecting block 9, which is rotatably connected to the side wall of the rotating column 25 to ensure the coordination and stability of the entire device during operation.
[0033] When the compactor 1 stops the compaction work on the road surface and needs to lift the roller 3, first, the push-pull rod 20 is started to move the connecting column 21 inward. At this time, the distance between the first fixing frame 18 and the second fixing frame 22 is shortened, causing the first fixing block 17 and the second fixing block 23 to deflect simultaneously. The first fixing block 17 deflects around the second rotating roller 16 as the axis, and the second fixing block 23 deflects around the first rotating roller 5 as the axis. At the same time, the upward lifting of the roller 3 through the first rotating roller 5 also moves upward, facilitating the completion of the later maintenance work on the roller 3, such as cleaning the difficult-to-remove dirt on the surface, lubricating or repairing and replacing the internal rotating parts, etc., thereby ensuring that the roller 3 can maintain good working performance and reliability in subsequent compaction work.
[0034] Working principle: When the compactor 1 is performing compaction on the road surface and needs to clean the roller 3, the roller 3 rolls and compacts the road surface, and the impurities on the road surface adhere to the surface of the roller 3. At this time, the impurities on the surface of the roller 3 are removed to the inside of the drawer 13 by the scraper 6. When the compactor 1 stops the compaction work on the road surface, the handle 15 is pulled outward. At this time, the clamping column 12 is extruded by the movement of the drawer 13, and the clamping column 12 deflects downward around the fixed column 11 as the axis. At this time, the spring 10 is extruded and deformed until the drawer 13 is separated from the cleaning box 7. The spring 10 loses extrusion and returns to its original position. Finally, the impurities inside the drawer 13 are cleaned.
[0035] When the compactor 1 stops the compaction work on the road surface and the lifting work of the roller 3 is needed, first, the push-pull rod 20 is started to move the connecting column 21 inward, at this time, the distance between the fixed frame one 18 and the fixed frame two 22 is shortened, so that the fixed block one 17 and the fixed block two 23 are deflected at the same time, the roller 3 is lifted upward through the upward lifting of the rotating roller one 5, and is also moved upward, so that the later maintenance work of the roller 3 is conveniently completed.
[0036] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
