Technical Field

[0001] This invention relates to the field of civil engineering, and more particularly to a mechanically rotatable device for improving the flatness of tunnel initial support. Background Technology

[0002] As one of my country's important calling cards, high-speed rail has extremely high requirements for construction standards and quality during its construction. In the sprayed concrete construction of tunnel engineering, conventional operations use a wet spraying robotic arm as a platform, and manual labor uses self-made extended shovels or scrapers welded to the front end of the wet spraying robotic arm to scrape the initial support arch frame to make the overall flatness of the initial support as smooth and flat as possible, providing reliable conditions for the subsequent waterproofing layer and secondary lining construction. However, there are certain problems: the construction angle is limited, and it cannot be used in all directions without blind spots. In addition, the range of manual use of shovels and scrapers is small and the efficiency is low. Moreover, there is a safety hazard of falling from heights. Therefore, this application proposes a mechanical rotatable device for the flatness of the tunnel initial support. Summary of the Invention

[0003] The purpose of this invention is to address the problems in the prior art, such as limited construction angle, inability to use it from all angles, small range and low efficiency of manual use of shovels and scrapers, and the safety hazard of falling from heights. The invention proposes a mechanically rotatable device for tunnel initial support flatness.

[0004] The technical solution of the present invention: a mechanical rotatable device for tunnel initial support flatness, comprising a frame and a rotating mechanism fixed to the top of the frame, the rotating mechanism comprising a fixed platform fixed to the bottom of the frame, the bottom of the fixed platform being provided with a connecting mechanism, and the bottom of the connecting mechanism being provided with a storage mechanism.

[0005] The storage mechanism includes a connecting bearing cover fixed to the bottom of the scraper connecting plate, a connecting bearing fixedly connected to the bottom of the connecting bearing cover, a storage box fixedly connected to the bottom of the connecting bearing, and an anti-slip layer on the inner wall of the connecting bearing. A leveling mechanism is fixedly connected to the outer wall of the storage box.

[0006] Optionally, the connecting mechanism includes an extension plate fixed to the bottom of the fixed platform. Connecting angle steels are fixedly connected to both sides of the outer wall of the extension plate, and multiple connecting stiffeners are fixedly connected to the top of the extension plate. A scraper connecting plate is fixedly connected to the side of the outer wall of the multiple connecting angle steels away from the extension plate. Two fixed terminals are fixedly connected to the bottom of the scraper connecting plate, and a bearing cover is fixedly connected to one side of the two fixed terminals.

[0007] Optionally, a fixed base is fixedly connected to one side of the top of the platform, a connecting block is fixedly connected to the top of the fixed base, and a driving block is rotatably connected to the top of the connecting block.

[0008] Optionally, a fixing plate is fixedly connected to the other side of the top of the platform, and a connecting end frame is fixedly connected to the top of the fixing plate near the center position. The bottom end of the connecting end frame passes through the fixing plate and is connected to the platform.

[0009] Optionally, the leveling mechanism includes two support ring frames fixed to the outer wall of the storage box, a plurality of support rods are fixedly connected between the two support ring frames, a plurality of connecting rods penetrate the outer wall of each of the plurality of support rods, one end of each of the plurality of connecting rods is connected to the storage box, and the other end of each of the plurality of connecting rods is fixedly connected to a support arm, and a crushing cone is fixedly connected to the end of each of the plurality of support arms away from the connecting rods.

[0010] Optionally, multiple support rods are fixedly connected between the two support ring frames, multiple collars are fixedly connected to the outer walls of the multiple support rods, a telescopic rod is fixedly connected to one side of the outer wall of the multiple collars, and a guide plate is fixedly connected to one end of the multiple telescopic rods.

[0011] Optionally, a plurality of buffer terminals are fixedly connected to one end of the outer wall of the plurality of guide plates away from the telescopic rod, and the ends of the plurality of buffer terminals away from the guide plates are fixedly connected to the storage box.

[0012] Optionally, multiple support rods 3 penetrate the outer walls of the two support ring frames, and multiple connecting rods 2 penetrate the outer walls of the multiple support rods 3. One end of the multiple connecting rods 2 is connected to the storage box, and a scraper is fixedly connected to the end of the multiple connecting rods 2 away from the storage box.

[0013] Optionally, the outer wall of the storage box involves multiple feed ports, which are evenly distributed between the scraper, guide plate and support arm.

[0014] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] This invention employs a rotating mechanism, enabling the leveling mechanism to rotate and level the concrete inside the tunnel, saving manpower. Its high structural stability reduces construction safety hazards. The scraper within the leveling mechanism scrapes the tunnel interior, while a crushing cone breaks up harder sections of concrete. This solves the problem of uneven initial support levels due to their large depth-to-depth ratio in tunnel engineering. It eliminates the need for manual shovel leveling, ensuring the quality of subsequent waterproofing and lining construction, shortening construction time, and saving construction costs.

[0016] Furthermore, by setting up collection boxes, the shotcrete scraped off during tunnel leveling can be recycled in a timely manner. It can be used to make sand-free concrete pads and arch support pads, saving the amount of shotcrete used. The scraped concrete debris is guided by scrapers and guide plates, preventing concrete debris from falling from heights and improving safety. Attached Figure Description

[0030] Example 1

[0031] like Figure 1 As shown, the present invention proposes a mechanically rotatable device for tunnel initial support flatness, including a platform 1 and a rotating mechanism fixed to the top of the platform 1. The rotating mechanism includes a fixed platform 16 fixed to the bottom of the platform 1. A connecting mechanism is provided at the bottom of the fixed platform 16, and a storage mechanism is provided at the bottom of the connecting mechanism. By setting the storage mechanism, the device can collect and reuse the scraped shotcrete waste, thus saving costs.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4and Figure 6 As shown, the storage mechanism includes a connecting bearing cover 2 fixed to the bottom of the scraper connecting plate 19, a connecting bearing 21 fixedly connected to the bottom of the connecting bearing cover 2, a storage box 23 fixedly connected to the bottom of the connecting bearing 21, and an anti-slip layer 22 on the inner wall of the connecting bearing 21. A leveling mechanism is fixedly connected to the outer wall of the storage box 23. The leveling mechanism includes two support ring frames 24 fixed to the outer wall of the storage box 23. Multiple support rods 25 are fixedly connected between the two support ring frames 24. Multiple connecting rods 26 penetrate the outer wall of each of the multiple support rods 25. One end of each connecting rod 26 is connected to the storage box 23, and a support arm 27 is fixedly connected to the other end of each connecting rod 26. A crushing cone 28 is fixedly connected to the end of each support arm 27 away from the connecting rod 26.

[0033] With the above setup, the connecting bearing cover 2 is fixed by the fixed terminal 110, allowing the connecting bearing 21 to drive the entire device to rotate via the rotating mechanism. This causes multiple scrapers 37 to rotate, leveling the uneven concrete on the outer surface of the tunnel. Multiple support arms 27 drive the crushing cone 28 to crush areas that the scrapers cannot reach, thus enabling the device to better level the tunnel. The scraped waste is guided to the feed inlet 35 by the guide plate 32, and the crushed material is transferred to the collection box 23 through the feed inlet 35. This allows the crushed material to be recycled in time with the scraped shotcrete, which can be used to make concrete sand-free pads and arch support pads, saving the amount of shotcrete used.

[0034] In this embodiment, the connecting bearing cover 2 is fixed by the fixed terminal 110, so that the connecting bearing 21 can drive the entire device to rotate through the rotating mechanism, thereby allowing multiple scrapers 37 to rotate. The scrapers 37 level the uneven concrete on the outer surface of the tunnel. Multiple support arms 27 drive the crushing cone 28 to crush the areas that the scrapers cannot reach, so that the device can better level the tunnel. The scraped waste is guided to the feed inlet 35 by the guide plate 32. The feed inlet 35 transmits the crushed material to the collection box 23, so that the crushed material can be recycled and reused in a timely manner.

[0035] Example 2

[0036] like Figure 1As shown, based on Embodiment 1, the connecting mechanism includes an extension plate 17 fixed to the bottom of the fixed platform 16. Connecting angle steels 18 are fixedly connected to both sides of the outer wall of the extension plate 17, and multiple connecting ribs 111 are fixedly connected to the top of the extension plate 17. A scraper connecting plate 19 is fixedly connected to the side of the outer wall of the multiple connecting angle steels 18 away from the extension plate 17. Two fixed terminals 110 are fixedly connected to the bottom of the scraper connecting plate 19, and a bearing cover 2 is fixedly connected to one side of the two fixed terminals 110.

[0037] With the above setup, the fixed platform 16 enables the rotating mechanism to drive the leveling mechanism below to rotate and level the tunnel. The scraper connecting plate 19 is fixed by the extension plate 17 and the connecting angle steel 18. The connecting angle steel 18 is made of 125×125×12 mm angle steel. Both the extension plate 17 and the scraper connecting plate 19 are made of 20 mm wide steel plates, which have high structural stability, reduce construction safety hazards, and enable the device to drive the leveling mechanism to rotate and level the tunnel surface, saving manpower.

[0038] like Figure 1 As shown, a fixed base 11 is fixedly connected to one side of the top of the platform 1, a connecting block 12 is fixedly connected to the top of the fixed base 11, and a driving block 13 is rotatably connected to the top of the connecting block 12. By setting the connecting block 12 and the driving block 13, the device can be hydraulically driven.

[0039] like Figure 1 As shown, a fixing plate 14 is fixedly connected to the other side of the top of the platform 1. A connecting end frame 15 is fixedly connected to the top of the fixing plate 14 near the center. The bottom end of the connecting end frame 15 passes through the fixing plate 14 and is connected to the platform 1. By setting the fixing plate 14 and the connecting end frame 15, the engineering machinery can be better fixed to the device.

[0040] like Figure 3 As shown, multiple support rods 29 are fixedly connected between the two support ring frames 24. Multiple collars 3 are fixedly connected to the outer walls of the multiple support rods 29. Telescopic rods 31 are fixedly connected to one side of the outer walls of the multiple collars 3. Guide plates 32 are fixedly connected to one end of the multiple telescopic rods 31. Multiple buffer terminals 36 are fixedly connected to one end of the outer wall of the multiple guide plates 32 away from the telescopic rods 31. The ends of the multiple buffer terminals 36 away from the guide plates 32 are fixedly connected to the storage box 23. By setting the telescopic rods 31 and buffer terminals 36, when the guide plates 32 guide the scraped large fragments into the storage box 23, it is possible to prevent the guide plates 32 from being smashed and deformed.

[0041] like Figure 3As shown, multiple support rods 33 penetrate the outer walls of the two support ring frames 24, and multiple connecting rods 34 penetrate the outer walls of the multiple support rods 33. One end of the multiple connecting rods 34 is connected to the storage box 23, and a scraper 37 is fixedly connected to the end of the multiple connecting rods 34 away from the storage box 23. By setting the scraper 37, the shotcrete in the tunnel can be scraped and leveled by the scraper 37.

[0042] like Figure 3 As shown, the outer wall of the storage box 23 involves multiple feed ports 35, which are evenly distributed between the scraper 37, the guide plate 32 and the support arm 27. By setting multiple feed ports 35, the device can absorb waste into the storage box 23.

[0043] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
