Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically a mobile tracked tunnel cutting trolley. Background Technology

[0002] The structure of a tunnel consists of two parts: the main building and the auxiliary equipment. The main building is composed of the tunnel body and the tunnel portal. The auxiliary equipment includes passing tunnels, fire-fighting facilities, emergency communication and drainage facilities. Long tunnels also have special ventilation and lighting equipment. Due to some reasons during the construction process, railway tunnels have a series of defects such as insufficient strength and thickness of the secondary lining and voids at the top of the lining, which seriously affect the safe operation of the railway. The secondary lining of the tunnel that fails the inspection must be demolished and reconstructed.

[0003] According to the utility model patent with Chinese patent application number 202420727352.6, a track-type cutting trolley for tunnel reconstruction and expansion is mentioned. This track-type cutting trolley can not only perform circumferential cutting of the tunnel, but also longitudinal cutting of the track. It eliminates the need to set up a frame to fix the trolley for each cut, making operation more convenient and improving construction efficiency. However, the diameter of this track-type cutting trolley is too short, making it inconvenient to perform horizontal and vertical cutting of the tunnel lining, resulting in low efficiency in cutting the inner wall lining of the tunnel. Therefore, it is necessary to propose a mobile tracked tunnel cutting table to solve the above-mentioned problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a mobile tracked tunnel cutting trolley, which has the advantages of being able to conveniently perform horizontal and vertical cutting of tunnel linings, thus solving the problem of inconvenience in performing horizontal and vertical cutting of tunnel linings in the prior art.

[0005] To achieve the above-mentioned purpose of conveniently cutting the tunnel lining horizontally and vertically, this utility model provides the following technical solution: a movable tracked tunnel cutting trolley, including a fixed frame, a first connecting ring and a second connecting ring fixedly installed on the outside of the fixed frame, a rolling assembly movably installed on the outside of both the first connecting ring and the second connecting ring, a connecting plate slidably installed between the first connecting ring and the second connecting ring, and a vertical cutting assembly movably installed on the top of the connecting plate;

[0006] The rolling assembly includes a disc, and discs are slidably mounted on the outside of both the first connecting ring and the second connecting ring. A balance bar is fixedly connected to the side of the disc, and a balance pulley is movably mounted at the end of the balance bar. A first drive motor is fixedly mounted on the front of the disc, and a gear is movably mounted on the output shaft of the first drive motor. External gear rings mesh with each other on the outer surfaces of the gears.

[0007] Furthermore, the vertical cutting assembly includes a second drive motor, the second drive motor is fixedly installed on the top of the connecting plate, a threaded rotating rod is fixedly connected to the output shaft of the second drive motor, threaded blocks are meshed with each other on the outer surface of the threaded rotating rod, a fixing plate is provided on the side of the threaded block, and a first cutting wheel is movably installed on the right side of the fixing plate.

[0008] Furthermore, the first connecting ring and the second connecting ring are respectively provided with a first annular groove and a second annular groove on their sides and top, and the balance pulley is slidably installed inside the first annular groove.

[0009] Furthermore, an external gear ring is provided inside the second annular groove, and a connecting plate is fixedly connected to the front side of the rear disk. A limiting groove is provided on the top of the connecting plate, and a threaded block is slidably installed inside the limiting groove.

[0010] Furthermore, cutting motors are fixedly installed on the sides of both the disc and the fixed plate, and a first cutting wheel and a second cutting disc are movably installed at the output shafts of the two sets of cutting motors, respectively.

[0011] Furthermore, a support plate is fixedly installed on the top of the fixed frame, and a walking track is movably installed on the bottom of the fixed frame.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This mobile tracked tunnel cutting trolley, by setting up a rolling assembly, when in use, by starting the first drive motor, the output shaft of the first drive motor will drive the gear to mesh with the external gear ring, so as to drive the disc to slide outside the first connecting ring and the second connecting ring. The disc is balanced and limited by the balance bar and balance pulley to prevent the disc from tilting and affecting the cutting accuracy of the second cutting disc.

[0014] This mobile tracked tunnel cutting trolley, equipped with a vertical cutting component, operates by activating a second drive motor. The output shaft of the second drive motor rotates a threaded rod. Due to the limiting effect of the limiting groove on the threaded block, the threaded block moves back and forth on the outer surface of the threaded rod, thereby driving the fixed plate, cutting motor, and first cutting wheel to move back and forth. Ultimately, this achieves vertical cutting of the tunnel lining. Furthermore, the connecting plate is fixedly connected to the rolling component. When the rolling component moves outside the first and second connecting rings, it can synchronously drive the vertical cutting component to move and cut at different positions. This allows for both horizontal and vertical cutting of the tunnel lining at different locations, improving the cutting efficiency of the tunnel lining. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 A movable tracked tunnel cutting trolley in this embodiment includes a fixed frame 1. A first connecting ring 3 and a second connecting ring 7 are fixedly installed on the outside of the fixed frame 1. Rolling components 6 are movably installed on the outside of both the first connecting ring 3 and the second connecting ring 7. A connecting plate 9 is slidably installed between the first connecting ring 3 and the second connecting ring 7. A vertical cutting component 10 is movably installed on the top of the connecting plate 9.

[0022] The rolling assembly 6 includes a disc 601. The disc 601 is slidably mounted on the outside of the first connecting ring 3 and the second connecting ring 7. A balance bar 602 is fixedly connected to the side of the disc 601. A balance pulley 603 is movably mounted at the end of the balance bar 602. A first drive motor 604 is fixedly mounted on the front of the disc 601. A gear 605 is movably mounted on the output shaft of the first drive motor 604. An external gear ring 606 meshes with each other on the outer surface of the gear 605.

[0023] In the implementation of the case, by setting up the rolling component 6, when in use, by starting the first drive motor 604, the output shaft of the first drive motor 604 will drive the gear 605 to mesh with the external gear ring 606, thereby driving the disc 601 to slide outside the first connecting ring 3 and the second connecting ring 7. The disc 601 is balanced and limited by the balance bar 602 and the balance pulley 603 to prevent the disc 601 from tilting and affecting the cutting accuracy of the second cutting disc 12.

[0024] In the implementation of the case, by setting up the vertical cutting component 10, when in use, by starting the second drive motor 101, the output shaft of the second drive motor 101 will drive the threaded rotating rod 102 to rotate. Due to the limiting effect of the limiting groove 13 on the threaded block 103, the threaded block 103 is threadedly connected to the outer surface of the threaded rotating rod 102 and moves back and forth, thereby driving the fixed plate 104, the cutting motor 11 and the first cutting wheel 105 to move back and forth, and finally realize the vertical cutting treatment of the tunnel inner wall lining.

[0025] In the implementation of the case, the connecting plate 9 is fixedly connected to the rolling component 6. When the rolling component 6 starts to move outside the first connecting ring 3 and the second connecting ring 7, it can synchronously drive the vertical cutting component 10 to move and cut at different positions, which can perform horizontal and vertical cutting on the tunnel inner wall lining at different positions, thereby improving the cutting efficiency of the tunnel inner wall.

[0026] When implementing this procedure, please follow these steps:

[0027] 1) First, the rolling assembly 6 drives the cutting motor 11 and the second cutting disc 12 to move, thereby cutting the tunnel lining;

[0028] 2) Then, the connecting plate 9 is moved synchronously by the rolling component 6;

[0029] 3) The vertical cutting component 10 is then used to cut the tunnel lining in the vertical direction;

[0030] 4) Finally, the first cutting wheel 105 and the second cutting disc 12 are driven by the rolling component 6 to perform cutting in the horizontal and vertical directions.

[0031] In summary, this mobile tracked tunnel cutting trolley, by setting up the rolling assembly 6, when in use, by activating the first drive motor 604, the output shaft of the first drive motor 604 will drive the gear 605 to mesh with the external gear ring 606, thereby driving the disc 601 to slide outside the first connecting ring 3 and the second connecting ring 7. The balance bar 602 and the balance pulley 603 balance and limit the disc 601, preventing the disc 601 from tilting and affecting the cutting accuracy of the second cutting disc 12.

[0032] Furthermore, by setting up the vertical cutting component 10, when in use, by starting the second drive motor 101, the output shaft of the second drive motor 101 will drive the threaded rotating rod 102 to rotate. Due to the limiting effect of the limiting groove 13 on the threaded block 103, the threaded block 103 is threadedly connected to the outer surface of the threaded rotating rod 102 and moves back and forth, thereby driving the fixed plate 104, the cutting motor 11 and the first cutting wheel 105 to move back and forth, and finally realize the vertical cutting of the tunnel inner wall lining. In addition, the connecting plate 9 is fixedly connected to the rolling component 6. When the rolling component 6 starts to move outside the first connecting ring 3 and the second connecting ring 7, it can synchronously drive the vertical cutting component 10 to move and cut at different positions, and can perform horizontal and vertical cutting of the tunnel inner wall lining at different positions, thereby improving the cutting efficiency of the tunnel inner wall.
