Description

Technical Field

[0001] This utility model relates to the field of tunnel pavement construction technology, and more specifically, to a rail-mounted self-propelled concrete tunnel pavement vibratory compaction device. Background Technology

[0002] In the complex and crucial field of high-speed railway tunnel construction, concrete vibration compaction plays a vital role. Its core objective is to comprehensively improve the various performance indicators of the concrete mixture. Specifically, this means significantly increasing the mixture's strength to withstand the immense pressure and impact of trains during high-speed railway operation; enhancing its stability to ensure the concrete structure remains robust and reliable under varying environmental conditions and over long-term use; and substantially improving its fatigue resistance to cope with the cyclical loads from repeated train travel. Extensive practical verification and professional research have demonstrated that this method of concrete vibration compaction is highly effective in achieving dense concrete pouring, providing a solid guarantee for the engineering quality of high-speed railway tunnels. Traditional plate vibrators rely on manual pulling, which suffers from problems such as high labor consumption, inconsistent manual pulling speed, and difficulty in controlling road surface compaction.

[0025] In this embodiment, the support moving mechanism 2 includes a support vertical plate 21, a support horizontal plate 22, moving wheels, and a drive motor 23. The support vertical plate 21 is disposed inside the track 1 and parallel to the length direction of the tunnel.

Several moving wheels are installed on the side of the support vertical plate 21 close to the track 1 and are in rolling connection with the track 1. The drive motor 23 is installed on the support horizontal plate 22 and is in transmission connection with one of the moving wheels.

[0026] Specifically, the track 1 has a horizontally arranged T-shaped structure, with its vertical portion positioned close to the supporting vertical plate 21. The moving wheels include an upper moving wheel 24 and a lower moving wheel 25, which are respectively located on the upper and lower sides of the horizontal portion of the track 1. The upper moving wheel 24 is in rolling connection with the top surface of the horizontal portion of the track 1, and the lower moving wheel 25 is in rolling connection with the bottom surface of the horizontal portion of the track 1. The drive motor 23 is connected to one of the upper moving wheels 24. By setting the upper moving wheel 24 and the lower moving wheel 25, the stability of the supporting moving mechanism 2 can be effectively improved.

[0027] In this embodiment, the supporting moving mechanism 2 also includes an upper bracket 26, which has an n-shaped structure and its bottom ends are respectively connected to the top surfaces of two supporting vertical plates 21, thereby further improving the stability of the supporting moving mechanism 2.

[0028] In this embodiment, the vibration mechanism 3 includes a vibrating plate 31, a vibration motor 32, and vibrating rods 33. The vibration motor 32 is mounted on the vibrating plate 31, and multiple vibrating rods 33 are installed at equal intervals at the bottom of the vibrating plate 31. The two ends of the vibrating plate 31 are connected to the support and moving mechanism 2 through a connecting assembly 5. Specifically, the connecting assembly 5 includes a telescopic column and a connecting rod 51.

The upper end of the rod 52 is connected to the supporting horizontal plate 22, and the lower end is slidably inserted into the sleeve 53. The limiting plate 54 is slidably disposed in the sleeve 53 and fixed to the lower end of the rod 52. The spring 55 is disposed in the sleeve 53 and sleeved on the rod 52. The two ends of the spring 55 are respectively connected to the limiting plate 54 and the inner top wall of the sleeve 53.

[0030] The track-mounted self-propelled concrete tunnel pavement vibratory compaction device in this embodiment also includes a compaction mechanism 6. The compaction mechanism 6 includes a compaction roller 61 and a rotating shaft 62. The rotating shaft 62 is fixed at both ends of the compaction roller 61, and the rotating shaft 62 is connected to the support moving component through the connecting component 5. The rotating shaft 62 is rotatably connected to the connecting component 5.

[0031] Specifically, the connecting assembly 5 connecting the compaction roller 61 and the telescopic column of the connecting assembly 5 connecting the vibrating plate 31 have the same structure; the connecting rod 51 in the connecting assembly 5 connecting the compaction roller 61 is a tubular structure, and the tubular connecting rod 51 is rotatably connected to the rotating shaft 62 through a bearing; the connecting rod 51 in the connecting assembly 5 connecting the vibrating plate 31 can be a tubular structure or a rod structure, and its two ends are fixedly connected to the sleeve 53 and the vibrating plate 31 respectively. The height of the vibrating plate 31 is higher than the height of the lower end of the compaction roller 61.

[0032] The rail-mounted self-propelled concrete tunnel pavement vibratory compaction device in this embodiment also includes a controller, which can be installed on the support plate 22 or the upper bracket 26. The controller is connected to the drive motor 23, the vibration motor 32 and the lifting column.

[0033] The working principle of the rail-mounted self-propelled concrete tunnel pavement vibratory compaction device in this embodiment is as follows:

[0034] By setting tracks 1 on both sides of the tunnel surface and installing a support moving mechanism 2 that can move on the tracks 1, the vibrating mechanism 3 is set between the two tracks 1 and connected to the support moving mechanism 2. The support moving mechanism 2 drives the vibrating mechanism 3 to move along the tracks 1, thereby replacing manual pulling and reducing labor consumption and avoiding the problem of inconsistent manual pulling speed.

[0035] The drive motor 23 drives the support moving mechanism 2 to move along the track 1, the vibration mechanism 3 vibrates the concrete, and the compaction mechanism 6 compacts the vibrated concrete pavement. The lifting column can adjust the height of the track 1, thereby adjusting the height of the support moving mechanism 2, the vibration mechanism 3 and the compaction mechanism 6, so as to adapt to the height of the concrete pavement in the tunnel.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
