Description

Technical Field

[0002] At present, the roadbed construction of the transition section of the railway adopts a combination of compaction equipment and manual compaction. The compaction equipment is mainly a common roller. The conventional roller is equipped with a frame and a shock-absorbing device on both sides, which makes it impossible for the rolling wheel to compact against the edge. There is a certain distance between the compaction boundary of the roller and the structure. Manual compaction is used within this distance. However, the manual tamping process is difficult to control, which can easily cause damage to the structure and the waterproof layer. It is easy to cause water seepage and settlement in the edge section. In addition, the thickness of the paving layer in the transition section is manually controlled, and the control accuracy is not high. It is easy to cause uneven settlement of the roadbed and deformation of the roadbed.

The rolling wheel body provided in the edge-touching rolling device is still rotatably connected to the connecting frame and the fixed frame. The connecting frames on both sides of the rolling wheel body may still collide with the structure, resulting in the rolling wheel body being unable to achieve edge-touching compaction.

The driving device drives the main shaft 21 to rotate on the first support plate 23, and the steel ring 22 compacts the road surface. The cams 51 at the output ends of the main shaft 21 are connected to the tamping device 52. The cam 51 drives the tamping device 52 to move upward. After the cam 51 is out of contact with the tamping device 52, the tamping device 52 compacts the edges of the two sides of the frame 10 under the action of gravity. The cam 51 rotates continuously, and the tamping device 52 compacts the edges of the two sides continuously.

[0024] In a preferred embodiment, the tamping device 52 includes a tamping plate 521, a vertical rod 522 and a beveled protrusion 523. Extension frames 11 are provided at both ends of the frame 10. A slide groove 12 is provided on the extension frame 11. The vertical rod 522 is slidably connected to the slide groove 12 in the vertical direction. The beveled protrusion 523 is fixedly connected to the side wall of the vertical rod 522. The tamping plate 521 is installed at the bottom end of the vertical rod 522, and the cam 51 is transmission-connected to the beveled protrusion 523. As the cam 51 rotates and contacts the beveled protrusion 523, the beveled cam 51 is continuously lifted vertically upward, and the vertical rod 522 moves upward in the slide groove 12. The bottom end of the vertical rod 522 moves upward with the tamping plate 521. After the cam 51 contacts the supporting wheel of the beveled protrusion 523, the tamping plate 521 and the vertical rod 522 move downward under the action of gravity to tamp the ground. The cam 51 rotates continuously, thereby realizing the tamping plate 521 continuously tamping the road surface on both sides of the frame 10.

[0025] Preferably, in one embodiment, a double-sided edge compacting device further comprises a speed changing device 60, wherein the speed changing device 60 comprises a first speed changing driving wheel 61, a second speed changing driving wheel 62, a first speed changing main shaft 63, a speed regulating wheel 64, a cam main shaft 65 and a cam main shaft driven wheel 66, wherein the first speed changing driving wheel 61 and the second speed changing driving wheel 62 are spaced apart and distributed at both ends of the main shaft 21, a pair of first speed changing main shafts 63 are respectively fixedly connected to the outer side walls of the first support plate 23, the speed regulating wheel 64 is axially slidably connected to the first speed changing main shaft 63, and is circumferentially rotatably connected to the first speed changing main shaft 63, and the speed regulating wheel 64 is A first speed-changing driven wheel 641, a second speed-changing driven wheel 642 and a cam main shaft driving wheel 643 are provided. The first speed-changing driving wheel 61 can mesh with the first speed-changing driven wheel 641, the second speed-changing driving wheel 62 can mesh with the second speed-changing driven wheel 642, the cam main shaft 65 is rotatably connected in the extension frame 11, the cam main shaft driven wheel 66 is fixedly installed at one end of the cam main shaft 65 and is located on the inner side of the extension frame 11, the cam 51 is fixedly connected to the other end of the cam main shaft 65 and is located on the outer side of the extension frame 11, and the cam main shaft driving wheel 643 meshes with the cam main shaft driven wheel 66 for transmission. The main shaft 21 adjusts the speed of the cam 51 through the speed change device 60. When the speed regulating wheel 64 slides toward the middle of the steel ring 22 on the first speed change main shaft 63, the first speed change driving wheel 61 meshes with the first speed change driven wheel 641. Since the diameter of the first speed change driving wheel 61 is larger than that of the first speed change driven wheel 641, the speed of the cam 51 is fast and the frequency of tamping of the tamping plate 521 is fast. When the speed regulating wheel 64 slides toward the outside of the steel ring 22 on the first speed change main shaft 63, the second speed change driving wheel 62 meshes with the second speed change driven wheel 642. Since the diameter of the second speed change driving wheel 62 is smaller than that of the second speed change driven wheel 642, the speed of the cam 51 is slow and the frequency of tamping of the tamping plate 521 is slow. The speed change device 60 of the utility model is only used as an example, and a more complex speed change device 60 in the prior art can also be used to adjust the different speeds of the cam 51.

The hydraulic motor 31 is installed in the first support plate 23, the first gear 32 is installed at the output end of the hydraulic motor 31, and the second gear 33 is fixedly installed on the main shaft 21, and the first gear 32 is meshed with the second gear 33. The hydraulic motor 31 drives the main shaft 21 through the transmission cooperation of the first gear 32 and the second gear 33, so that the cam 51 is driven to rotate through the speed change device 60, thereby realizing the tamping operation of the tamping device 52.

[0027] In a preferred embodiment, the ramming device 52 also includes a spring 524, and a plurality of springs 524 are installed between the bottom end of the extension frame 11 and the top end of the ramming plate 521. In a natural state, the spring 524 is in a stretched state, and the ramming plate 521 is pulled upward by the pulling force of the spring 524. This can reduce the lifting force of the cam 51 on the beveled protrusion 523 during the rotation process, thereby extending the service life of the speed change device 60 and the drive device.

[0028] In a preferred embodiment, the rolling device 20 further includes a second support plate 24 and an eccentric wheel 25, wherein a plurality of eccentric wheels 25 are fixedly mounted on the main shaft 21, and a pair of second support plates 24 are fixedly mounted in the steel ring 22 and are located on the inner side of the first support plate 23. While the hydraulic motor 31 drives the main shaft 21 to rotate and drive the tamping devices 52 on both sides, the main shaft 21 drives the rotation of the eccentric wheel 25 inside the steel ring 22, and the second support plate 24 is fixedly connected to the steel ring 22, so that the steel ring 22 is vibrated and compacted on the roadbed.

[0029] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments.
