[0002] A tunnel inner wall leveling device is a device used in tunnel construction, mainly for leveling and trimming the inner wall of the tunnel. During tunnel construction, there will be protruding mud blocks on the inner wall of the tunnel. If the inner wall of the tunnel is not flat enough, it will affect the construction efficiency and quality. Therefore, it is necessary to appropriately level the inner wall of the tunnel. At present, the efficiency of leveling the inner wall of the tunnel is low and not flat enough, which brings inconvenience to the tunnel construction operation.

[0003] In the patent application with the publication number of CN217380547U in the prior art, a tunnel inner wall leveling device for tunnel construction is disclosed, including a support frame, a support rod, and a scraping plate. This device controls the scraping plate to efficiently level the arc-shaped inner wall of the tunnel, ensuring the construction quality of the tunnel.

[0004] However, in the prior art, when this device controls the scraping plate to remove hard protrusions, the stress on the support frame and the support rod is relatively large, and it is easy to break. Therefore, this device is not suitable for removing hard protrusions, reducing the practicability of this device. Content of the Utility Model

[0005] The purpose of the utility model is to provide a tunnel inner wall leveling device, aiming to solve the problem that in the prior art, when this device controls the scraping plate to remove hard protrusions, the stress on the support frame and the support rod is relatively large, and it is easy to break. Therefore, this device is not suitable for removing hard protrusions, reducing the practicability of this device.

[0006] To achieve the above purpose, the utility model provides a tunnel inner wall leveling device, including a support frame, a support rod, a scraping plate, a base, a mounting seat, a rotating roller, and two driving mechanisms. The driving mechanism includes a driving motor, a driving shaft, a connecting component, a connecting rod, and a fixing frame. The support frame is slidably connected to the support rod. The scraping plate is fixedly connected to the support rod and is located above the support rod. The mounting seat is fixedly connected to the base and is located below the support frame. The rotating roller is rotatably connected to the mounting seat and the support frame. The two driving mechanisms are arranged at both ends of the base. The driving motor is fixedly connected to the base. The driving shaft is fixedly connected to the output end of the driving motor. The connecting component is arranged between the driving shaft and the connecting rod. The fixing frame is fixedly connected to the connecting rod.

[0007] Among them, the connecting assembly includes a spline shaft and a connecting seat, the connecting seat has a spline groove, the spline shaft is fixedly connected to the drive shaft, passes through the connecting seat, and is located in the spline groove, and the connecting seat is fixedly connected to the connecting rod and is located below the connecting rod.

[0008] Wherein, the driving mechanism further includes a supporting assembly, the base has two mounting grooves, and are respectively located below the two connecting seats, and the supporting assembly is arranged in the mounting grooves.

[0009] Wherein, the supporting assembly includes a mounting frame, a rotating shaft and a pulley, the connecting seat has a slide groove, the mounting frame is fixedly connected to the base and is located in the mounting groove, the rotating shaft is rotatably connected to the mounting frame and the pulley, and the pulley is rotatably connected to the connecting seat and is located in the slide groove.

[0010] Wherein, the driving mechanism also includes a protective cover and two supporting columns, the protective cover is fixedly connected to the base, and the driving motor is located below the protective cover, and the two ends of the two supporting columns are fixedly connected to the base and the protective cover respectively.

[0011] The utility model discloses a tunnel inner wall flattening device. When flattening the tunnel inner wall, the base is moved into the tunnel so that the flattening plate contacts the tunnel inner wall, and the two driving motors are started at the same time. The driving motor drives the connecting rod and the fixed frame to rotate. The two fixed frames simultaneously drive the support frame and the flattening plate to rotate with the rotating roller as the central axis. The flattening plate removes protrusions in the tunnel. The two driving motors drive the support rod and the flattening plate to rotate by controlling the two fixed frames. The distance between the fixed frame and the flattening plate is short, which shortens the torque of the flattening plate, thereby reducing the stress on the support rod and the flattening plate. The support rod is not easy to break, and the inner wall of the tunnel with hard soil can be flattened, thereby increasing the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0018] Please refer to Figures 1 to 4 , wherein, Figure 1 is a schematic structural diagram of the tunnel inner wall leveling device of the present utility model, Figure 2 is the Figure 1 enlarged partial structural view of part A of the present utility model, Figure 3 is a schematic structural diagram of the tunnel inner wall leveling device of the present utility model in another direction, Figure 4 is a schematic structural diagram of the connection component of the tunnel inner wall leveling device of the present utility model.

[0019] The present utility model provides a tunnel inner wall leveling device, including a bracing frame 104, a bracing rod 105, a shoveling flat plate 106, a base 101, a mounting seat 102, a rotating roller 103 and two driving mechanisms. The driving mechanism includes a driving motor 107, a driving shaft 108, a connection component, a protective cover 113, two support columns 112, a support component, a connecting rod 110 and a fixed frame 111. The base 101 has two mounting grooves 115. The connection component includes a spline shaft 118 and a connecting seat 109. The connecting seat 109 has a spline groove 119. The support component includes a mounting bracket 120, a rotating shaft 116 and a pulley 117. The connecting seat 109 has a chute 114. By the foregoing solution, in the prior art, when the device controls the shoveling flat plate 106 to remove too hard protrusions, the stress on the bracing frame 104 and the bracing rod 105 is relatively large and it is easy to break. Therefore, the device is not suitable for removing too hard protrusions, reducing the practicability of the device.

[0020] In this embodiment, the support frame 104 is slidably connected to the support rod 105. The shovel plate 106 is fixedly connected to the support rod 105 and is located above the support rod 105. The mounting seat 102 is fixedly connected to the base 101 and is located below the support frame 104. The rotating roller 103 is rotatably connected to the mounting seat 102 and the support frame 104. The two driving mechanisms are arranged at both ends of the base 101. The driving motor 107 is fixedly connected to the base 101. The driving shaft 108 is fixedly connected to the output end of the driving motor 107. The connecting assembly is arranged between the driving shaft 108 and the connecting rod 110. The fixed frame 111 is fixedly connected to the connecting rod 110. When shoveling the inner wall of the tunnel, the base 101 is moved into the tunnel to make the shovel plate 106 contact the inner wall of the tunnel. At the same time, the two driving motors 107 are started. The driving motor 107 drives the connecting rod 110 and the fixed frame 111 to rotate. The two fixed frames 111 drive the support frame 104 and the shovel plate 106 to rotate around the rotating roller 103 as the central axis at the same time. The shovel plate 106 shovels the protrusions in the tunnel. The two driving motors 107 drive the support rod 105 and the shovel plate 106 to rotate by controlling the two fixed frames 111. The distance between the fixed frame 111 and the shovel plate 106 is short, which shortens the torque of the shovel plate 106. Furthermore, the stress on the support rod 105 and the shovel plate 106 is reduced, and the support rod 105 is not easily broken. It can shovel the inner wall of the tunnel with harder soil, thereby increasing the practicability of the device.

[0021] Further, the spline shaft 118 is fixedly connected to the driving shaft 108, penetrates through the connecting seat 109, and is located in the spline groove 119. The connecting seat 109 is fixedly connected to the connecting rod 110 and is located below the connecting rod 110.

[0022] In this embodiment, the connecting seat 109 and the driving shaft 108 are connected together through the spline shaft 118 and the spline groove 119. The spline shaft 118 and the spline groove 119 transfer power from the driving shaft 108 to the connecting seat 109. This connection method can evenly distribute stress, improve the connection strength, reduce the possibility of the driving shaft 108 and the connecting seat 109 falling off, and further increase the structural stability of the device.

[0023] Further, the base 101 has two mounting grooves 115, which are respectively located below the two connecting seats 109. The support assembly is arranged in the mounting grooves 115.

[0024] Furthermore, the connecting seat 109 has a slide groove 114, the mounting frame 120 is fixedly connected to the base 101 and is located in the mounting groove 115, the rotating shaft 116 is rotationally connected to the mounting frame 120 and the pulley 117, and the pulley 117 is rotationally connected to the connecting seat 109 and is located in the slide groove 114.

[0025] In this embodiment, when the driving motor 107 drives the connecting seat 109 and the connecting rod 110 to rotate, the pulley 117 rotates with the rotating shaft 116 as the central axis and rotates in the sliding groove 114. The pulley 117 and the mounting frame 120 support the connecting seat 109 and the connecting rod 110 to ensure that the connecting seat 109 can rotate normally.

[0026] Furthermore, the protective cover 113 is fixedly connected to the base 101 , and the driving motor 107 is located below the protective cover 113 , and both ends of the two supporting columns 112 are fixedly connected to the base 101 and the protective cover 113 , respectively.

[0027] In this embodiment, when leveling the tunnel, the shoveling plate 106 shovels the soil, and the protective cover 113 protects the components on the base 101. The fallen soil will not hit the drive motor 107 and other components, ensuring that the device can operate normally and increasing the structural stability of the device.

[0028] When the utility model is used to flatten a tunnel, the base 101 is moved into the tunnel so that the flat plate 106 contacts the inner wall of the tunnel, and the two driving motors 107 are started at the same time. The driving motor 107 drives the connecting rod 110 and the fixed frame 111 to rotate. The two fixed frames 111 simultaneously drive the support frame 104 and the flat plate 106 to rotate around the rotating roller 103 as the central axis. The flat plate 106 removes protrusions in the tunnel. The two driving motors 107 drive the support rod 105 and the flat plate 106 to rotate by controlling the two fixed frames 111. The distance between the fixed frame 111 and the flat plate 106 is short, which shortens the torque of the flat plate 106, thereby reducing the stress on the support rod 105 and the flat plate 106. The support rod 105 is not easy to break, and the inner wall of the tunnel with hard soil can be flattened, thereby increasing the practicality of the device.

[0029] The above disclosure is only a preferred embodiment of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiment and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
