Description

Technical Field

[0001] The utility model relates to a pressing and aligning device for the production of tunnel steel arch frames, belonging to the technical field of steel arch frame production. Background Art

[0002] The steel arch frame is a support measure for strengthening underground projects by using bent I-beams. It can form a composite support arch frame with bolts, shotcrete, and steel meshes, and is widely used in projects such as tunnels, subways, hydropower stations, and underground chambers. During the production of steel arch frames, the whole I-beam needs to be cut to process into sizes that meet the construction requirements. Inevitably, there will be tailings remaining after the cutting of the whole I-beam, which will cause a large waste of I-beam tailings. In the prior art, manual or welding robots are used to butt-weld the I-beam tailings with new whole I-beams to avoid waste of I-beam tailings and save costs.

[0026] As Figures 1-5As shown in the figure, this embodiment provides a pressing and aligning device for the production of tunnel steel arch frames. In some embodiments, it includes a first aligning mechanism 1, a first pressing mechanism 2 arranged on one side of the first aligning mechanism 1, a second aligning mechanism 3, and a second pressing mechanism 4 arranged on one side of the second aligning mechanism 3.

The second roller 34 moves towards the third roller 36 to fix the second section of I-beam 10 in the horizontal direction. The second pressing mechanism 4 includes a sixth roller 45 and a movable fifth roller 44. The fifth roller 44 moves towards the sixth roller 45 to fix the second section of I-beam 10 in the vertical direction.

[0027] In some embodiments, it further includes a first base 5 and a second base 6 connected thereto. An installation platform 7 is installed on the second base 6. The first aligning mechanism 1 and the first pressing mechanism 2 are installed on the first base 5, the second aligning mechanism 3 is installed on the second base 6, and the second pressing mechanism 4 is installed on the installation platform 7.

[0028] In some embodiments, the first aligning mechanism 1 is used to clamp the first section of I-beam 9 to achieve clamping and fixing of the first section of I-beam 9 in the horizontal direction. The first aligning mechanism 1 further includes a first mounting seat 12, a first driving mechanism 11 fixedly connected to the first mounting seat 12, a first guide rail 15, and a first slider 13 connected to the lower part of the first moving seat 14. The first slider 13 is slidably connected to the first guide rail 15. The output end of the first driving mechanism 11 is fixedly connected to the first moving seat 14. The first driving mechanism 11 is used to drive the first moving seat 14 to move towards or away from the first fixed seat 16 on the first guide rail 15.

[0029] Furthermore, the first mounting seat 12, the first guide rail 15, and the first fixed seat 16 are installed on the first base 5. The first guide rail 15 is located between the first mounting seat 12 and the first fixed seat 16.

[0030] In this embodiment, when the first driving mechanism 11 drives the first moving seat 14 to move on the first guide rail 15 in the direction close to the first fixed seat 16, at this time, the first moving seat 14 approaches the first fixed seat 16, and the first moving seat 14 and the first fixed seat 16 clamp the first section of I-beam 9 to achieve the horizontal fixation of the first section of I-beam 9. When the first driving mechanism 11 drives the first moving seat 14 to move on the first guide rail 15 in the direction away from the first fixed seat 16, at this time, the first moving seat 14 and the first fixed seat 16 move away from each other to release the first section of I-beam 9 and enable the first section of I-beam 9 to move forward normally. Exemplarily, the first driving mechanism 11 is a linear electric cylinder or a cylinder.

[0031] In some embodiments, the first pressing mechanism 2 is used to press the first section of I-beam 9 to achieve the vertical pressing and fixation of the first section of I-beam 9. The first pressing mechanism 2 further includes a first mounting frame 22 and a second driving mechanism 21 fixedly connected to the first mounting frame 22. The output end of the second driving mechanism 21 is fixedly connected to the pressing plate 23, and the pressing plate 23 is located above the first roller 24. The second driving mechanism 21 is used to drive the pressing plate 23 to move up and down.

[0032] Furthermore, the first mounting frame 22 is mounted on the first base 5 and is located on one side of the first alignment mechanism 1. The first roller 24 is rotatably arranged in the first mounting frame 22.

[0033] In this embodiment, when the second driving mechanism 21 drives the pressing plate 23 to move in the direction close to the first roller 24, at this time, the pressing plate 23 approaches the first roller 24, and the pressing plate 23 presses the first section of I-beam 9 against the first roller 24 to achieve the vertical fixation of the first section of I-beam 9. When the second driving mechanism 21 drives the pressing plate 23 to move in the direction away from the first roller 24, at this time, the pressing plate 23 and the first roller 24 move away from each other to release the first section of I-beam 9 and enable the first section of I-beam 9 to move forward normally on the rotatable first roller 24. Exemplarily, the second driving mechanism 21 is a linear electric cylinder or a cylinder.

[0034] In some embodiments, the second alignment mechanism 3 is used to clamp the second section of I-beam 10 to achieve horizontal clamping and fixing of the second section of I-beam 10. The second alignment mechanism 3 further includes a second mounting base 32, a third driving mechanism 31 fixedly connected to the second mounting base 32, a second moving base 33 fixedly connected to the output end of the third driving mechanism 31, a second slider 38 connected to the lower part of the second moving base 33, a second guide rail 39 slidably connected to the second slider 38, and a second fixing base 35. The second idler 34 is rotatably mounted in the second moving base 33, and the third idler 36 is rotatably mounted in the second fixing base 35. The third driving mechanism 31 is used to drive the second moving base 33 and the second idler 34 to move on the second guide rail 39 in a direction close to or away from the second fixing base 35 and the third idler 36.

[0035] Further, the second mounting base 32, the second guide rail 39, and the second fixing base 35 are mounted on the second base 6. The second guide rail 39 is located between the second mounting base 32 and the second fixing base 35. A rotatable fourth idler 37 is provided on one side of the second moving base 33.

[0036] In this embodiment, when the third driving mechanism 31 drives the second moving base 33 and the second idler 34 to move on the second guide rail 39 in a direction close to the second fixing base 35 and the third idler 36, at this time, the second moving base 33 and the second idler 34 approach the second fixing base 35 and the third idler 36, and the second section of I-beam 10 is clamped by the second idler 34 and the third idler 36 to achieve horizontal fixing of the second section of I-beam 10. When the third driving mechanism 31 drives the second moving base 33 and the second idler 34 to move on the second guide rail 39 in a direction away from the second fixing base 35 and the third idler 36, at this time, the second idler 34 and the third idler 36 move away from each other to release the second section of I-beam 10, so that the second section of I-beam 10 can move forward normally from the rotatable fourth idler 37. Exemplarily, the third driving mechanism 3 is a linear electric cylinder or a cylinder.

[0037] In some embodiments, the second pressing mechanism 4 is used to press the second section of I-beam 10 to achieve vertical pressing and fixing of the second section of I-beam 10. The second pressing mechanism 4 further includes a second mounting frame 46, a third slider 43 slidably connected in the second mounting frame 46, and a rotary handle 41 connected to the third slider 43 through a screw 42. The fifth idler 44 is arranged in the third slider 43 and is located above the sixth idler 45. The rotary handle 41 drives the third slider 43 and the fifth idler 44 to move up and down through the screw 42.

[0038] Further, the second mounting bracket 46 is mounted on the mounting platform 7 and is located on one side of the second alignment mechanism 3. The fifth roller 44 and the sixth roller 45 are rotatably arranged in the second mounting bracket 46. Among them, the sixth roller 45 can only rotate and cannot move up and down, while the fifth roller 44 can rotate and also move.

[0039] In this embodiment, by rotating the rotary handle 41, the screw 42 rotates and moves up and down, and further the third slider 43 fixedly connected to the end of the screw 42 moves up and down, thereby realizing the up and down movement of the fifth roller 44. When the rotary handle 41 drives the fifth roller 44 to move towards the sixth roller 45, at this time the fifth roller 44 and the sixth roller 45 approach each other, and the second section of I-beam 10 is pressed against the sixth roller 45 by the fifth roller 44 to realize the vertical fixation of the second section of I-beam 10. When the rotary handle 41 drives the fifth roller 44 to move away from the sixth roller 45, at this time the fifth roller 44 and the sixth roller 45 move away from each other to release the second section of I-beam 10, so that the second section of I-beam 10 can move forward normally on the rotatable sixth roller 45.

[0040] During use, the first section of I-beam 9 passes through between the first moving seat 14 and the first fixed seat 16 of the first alignment mechanism 1, and between the pressing plate 23 and the first roller 24 of the first pressing mechanism 2. The second section of I-beam 10 passes through between the second roller 34 and the third roller 36 of the second alignment mechanism 3, and between the fifth roller 44 and the sixth roller 45 of the second pressing mechanism 4. The first section of I-beam 9 and the second section of I-beam 10 are butted against each other. The first alignment mechanism 1 positions the first section of I-beam 9 in the horizontal direction, and the second alignment mechanism 3 positions the second section of I-beam 10 in the horizontal direction, so that the two sections of I-beams can be completely aligned in the horizontal direction. The first pressing mechanism 2 positions the first section of I-beam 9 in the vertical direction, and the second pressing mechanism 4 positions the second section of I-beam 10 in the vertical direction, so that the two sections of I-beams can be completely aligned in the vertical direction. Thus, the pressing and alignment device provided by the present utility model enables the two sections of I-beams to be completely fixed and aligned during welding through the common alignment in the vertical and horizontal directions, avoiding problems such as misalignment and angular deviation during the butt welding of the two sections of I-beams, and ensuring the product quality of the I-beam after welding. After the two sections of I-beams are completely fixed and aligned, the welding robot 8 performs the welding operation on the two sections of I-beams at the butt joint.
