[0054] The supporting arch 1 is provided with a curved track 11 adapted to the tunnel contour;

[0055] The cloth hanging overhead crane 2 includes a cloth hanging vehicle body 21 connected to the curved track 11, a cloth hanging driving mechanism 22 for driving the cloth hanging vehicle body 21 to move along the curved track 11, and a tarpaulin reel 23 for installing a tarpaulin;

[0056] The climb welding overhead crane 3 includes a climb welding vehicle body 31 connected to the curved track 11 , a climb welding driving mechanism 32 for driving the climb welding vehicle body 31 to move along the curved track 11 , and a climb welding machine 33 mounted on the climb welding vehicle body 31 .

[0057] Specifically, a set of cloth hanging wheels 25 are respectively provided at both ends of the cloth hanging vehicle body 21 along the length direction, and the cloth hanging driving mechanism 22 drives the cloth hanging wheels 25 by electricity to move on the curved track 11. A set of welding climbing wheels 35 are respectively provided at both ends of the weld climbing vehicle body 31 along the length direction, and the welding climbing driving mechanism 32 drives the welding climbing wheels 35 by electricity to move on the curved track 11.

[0058] During operation, the above-mentioned device, the cloth-hanging overhead crane 2, can lay the tarpaulin on the tunnel surface; the climbing welding overhead crane 3 moves closely behind the cloth-hanging overhead crane 2, and can weld the newly laid tarpaulin to the previous tarpaulin. As described above, the tunnel cloth-hanging device provided by this application realizes the integrated construction of cloth-hanging and climbing welding, effectively improving the efficiency and quality of tarpaulin construction, and laying a solid foundation for the overall quality control of tunnel projects.

[0059] Optionally, the cloth hanging vehicle body 21 and the climbing welding vehicle body 31 can be formed into a whole by welding or screwing.

[0060] Continue to refer to Figure 1 The support arch 1 utilizes 22-inch I-beams for transverse and longitudinal support. Circumferentially, 22-inch I-beams are arranged according to the tunnel's contours, with three longitudinally arranged circumferential I-beams. Atop the circumferential I-beams are installed wide toothed belts for the fabric hanging crane 2 and the welding crane 3. The support arch 1 is equipped with a work platform 12 for manual construction. The base of the support arch 1 is equipped with wheels 13 for the mobile device. The support arch 1 also houses the hydraulic and electrical systems 5 that power the entire device.

[0061] Continue to refer to Figure 2 In this embodiment, a waterproof cloth reel 23 is provided on each side of the cloth hanging vehicle body 21 along the width direction, enabling the cloth hanging overhead crane 2 to perform bidirectional construction. Accordingly, there are two climbing welding overhead cranes 3, one on each side of the cloth hanging overhead crane 2 along the width direction, enabling bidirectional construction.

[0062] Reference Figure 1 and Figure 3 The device further comprises a longitudinal pressing mechanism 4 installed below the supporting arch 1, and the longitudinal pressing mechanism 4 comprises:

[0063] A longitudinal pressing plate 41 perpendicular to the horizontal plane, the longitudinal pressing plate 41 is used to press the waterproof cloth during the laying process;

[0064] The longitudinal pressure assembly is used to apply pressure to the longitudinal pressure plate 41 to compress the waterproof cloth.

[0065] Specifically, the longitudinal pressure assembly includes:

[0066] A first rotating shaft 42, one end of which is rotatably connected to the supporting arch 1, and the other end of which is connected to the longitudinal pressing plate 41;

[0067] The first hydraulic cylinder 43 has a cylinder body and a piston rod hinged to the supporting arch 1 and the abdomen of the first rotating shaft 42 respectively.

[0068] During the process of the above device, the piston rod of the first hydraulic cylinder 43 extends to push the longitudinal pressing plate 41 to press the waterproof cloth, thereby avoiding the displacement of the waterproof cloth and ensuring the overall construction quality of the waterproof cloth.

[0069] In this embodiment, there are two longitudinal pressing mechanisms 4 symmetrically arranged on both sides of the supporting arch 1 to achieve bidirectional construction.

[0070] Reference Figure 4 The arc track 11 includes three arc guide rails 111 arranged in parallel and spaced apart. The three arc guide rails 111 are respectively a first guide rail, a second guide rail and a third guide rail. The second guide rail is located between the first guide rail and the third guide rail, and the distance between the first guide rail and the second guide rail is greater than the distance between the second guide rail and the third guide rail.

[0071] The two ends of the cloth hanging crane 2 are respectively connected to the first guide rail and the third guide rail;

[0072] Both ends of the climbing welding crane 3 are connected to the second guide rail and the third guide rail respectively.

[0073] The above structure enables the climbing welding crane 3 to weld one side edge of the waterproof cloth to achieve the connection of the waterproof cloth.

[0074] Reference Figure 5 The cloth hanging crane 2 also includes an auxiliary roller 26 for guiding the waterproof cloth. The auxiliary roller 26 can improve the smoothness of the waterproof cloth.

[0075] Reference Figure 5 and Figure 6 The cloth hanging overhead crane 2 further includes a transverse pressing mechanism 24 mounted on the cloth hanging vehicle body 21. The transverse pressing mechanism 24 includes:

[0076] A transverse pressing plate 241 is used to press the tarpaulin during its laying;

[0077] The pressure plate angle adjustment assembly is used to adjust the angle of the transverse pressure plate 241 during the laying of the waterproof cloth.

[0078] Specifically, the pressure plate angle adjustment assembly includes two second hydraulic cylinders 242 symmetrically arranged on either side of the transverse pressure plate 241. The cylinder body and piston rod of each second hydraulic cylinder 242 are respectively hinged to the cloth hanging vehicle body 21 and the transverse pressure plate 241. In order to improve the smoothness of the movement of the transverse pressure plate 241, the number of pressure plate angle adjustment assemblies in this embodiment is multiple and spaced apart along the length direction of the transverse pressure plate 241.

[0079] In the above structure, by controlling the different extension lengths of the two second hydraulic cylinders 242 in each group of pressure plate angle adjustment components, the angle of the transverse pressure plate 241 relative to the horizontal plane can be controlled, so that the transverse pressure plate 241 can fit tightly with the waterproof cloth, thereby improving the laying quality of the waterproof cloth.

[0080] Reference Figure 6 and Figure 7 The lateral pressing mechanism 24 also includes a lateral pressure component for applying pressure to the lateral pressing plate 241 to press the waterproof cloth.

[0081] Specifically, the lateral pressure assembly includes:

[0082] The elastic support rod 243 is installed at the power output end of the pressure plate angle adjustment assembly;

[0083] A sliding shaft 244, one end of which is slidably connected to the elastic support rod 243, and the other end of which is connected to the horizontal pressure plate 241;

[0084] The elastic member 245 is disposed between the elastic support rod 243 and the sliding shaft 244 .

[0085] During the process of the above device, the elastic member 245 pushes the sliding shaft 244, and then drives the horizontal pressing plate 241 to press the waterproof cloth, thereby further ensuring the overall construction quality of the waterproof cloth.

[0086] Based on the above structure, two cylinder mounting rods are provided on the cloth hanging vehicle body 21, each of which is provided with multiple first lugs. Two rows of second lugs are symmetrically arranged on the elastic support rod 243, each row of second lugs consisting of multiple second lugs. The cylinder body of each second hydraulic cylinder 242 is hinged to one of the first lugs, and the piston rod of each second hydraulic cylinder 242 is hinged to one of the second lugs. This arrangement allows the elastic support rod 243 to be mounted on the power output end of the second hydraulic cylinder 242, simultaneously enabling relative rotation between the piston rod of the second hydraulic cylinder 242 and the transverse pressure plate 241.

[0087] Continue to refer to Figure 6 and Figure 7A plurality of spring mounting seats with a hollow structure are installed on the elastic support rod 243 at intervals along its length direction, and an elastic member 245 is provided in each spring mounting seat (in this embodiment, the elastic member 245 is specifically a spring); the number of sliding shafts 244 is also multiple and corresponds one to one with the multiple spring mounting seats, and one end of each sliding shaft 244 can be slidably inserted into the corresponding spring mounting seat and abut against the elastic member 245, and the other end of the sliding shaft 244 is welded or screwed to the horizontal pressure plate 241.

[0088] In this embodiment, both the longitudinal pressure plate 41 and the transverse pressure plate 241 are made of a high-strength plastic plate embedded in a U-shaped channel steel. The edges of the high-strength plastic plate are rounded, and the pressure plate length is slightly longer than the length of the U-shaped channel steel. This arrangement prevents the pressure plate from damaging the waterproof fabric.

[0089] Reference Figure 8 The climbing welding crane 3 also includes a welding machine angle adjustment mechanism 34 for adjusting the angle of the climbing welding machine 33. The welding machine angle adjustment mechanism 34 includes:

[0090] A second rotating shaft 341, one end of which is rotatably connected to the climbing welding vehicle body 31, and the other end of which is connected to the climbing welding machine 33;

[0091] The third hydraulic cylinder 342 has a cylinder body and a piston rod hinged to the climb welding vehicle body 31 and the belly of the second rotating shaft 341 respectively.

[0092] In the above structure, the third hydraulic cylinder 342 can drive the second rotating shaft 341 and the climbing welding machine 33 on the second rotating shaft 341 to rotate relative to the climbing welding vehicle body 31, so that the climbing welding machine 33 is at the best welding angle, thereby improving the climbing welding quality.

[0093] In summary, the tunnel tarpaulin hanging device provided by this application integrates tarpaulin hanging and climbing welding, effectively improving the efficiency and quality of tarpaulin construction. In addition, the device is equipped with a longitudinal pressure plate 41 and a transverse pressure plate 241 for pressing the tarpaulin, effectively controlling the slack of the tarpaulin and ensuring the overall construction quality of the tarpaulin.
