Description

Technical Field

[0001] The utility model relates to the technical field of coal mine operations. More specifically, the utility model relates to a new type of bendable stainless steel corrugated flange gas drainage pipeline. Background Technique

[0002] At present, the following types of pipelines are currently used for gas drainage in coal mines: polyethylene pipes, polyvinyl chloride pipes, ordinary steel pipes, and plastic-coated steel pipes. Although polyethylene and polyvinyl chloride are corrosion-resistant, their flame retardancy and antistatic properties are difficult to meet the requirements. Even if the requirements are met, the quality of the pipe materials is affected due to excessive additives. Ordinary steel is inconvenient for installation and production due to its heavy weight.

[0003] In existing coal mine operations, the steel welded pipes used for gas drainage, whether straight-seam or spiral welded pipes, are only suitable for positive pressure ventilation and fluid transportation. For negative pressure, thick-walled steel pipes are required. Thin walls are easily sucked and deformed, affecting the efficiency of gas drainage.

[0004] After retrieval, the Chinese patent with the application number CN201420663234.X discloses a coal mine gas drainage pipeline. The utility model increases the radial compressive strength of the pipe body by setting reinforcing ribs on the outer surface of the pipe body, can well adapt to the working conditions of the gas drainage system, and can avoid the pipe body being sucked or deformed under high negative pressure conditions. In addition, the cross-sectional shape of the reinforcing rib is set as a W shape or a double U shape, and its radial compressive strength is better. At the same time, when using a wire rope to hoist the pipe body, the W-shaped or double U-shaped reinforcing rib has two stress points, and the stress is more balanced, which can avoid the deformation and fracture of the reinforcing rib on the pipe body due to excessive stress and uneven stress.

[0005] However, when the above drainage pipeline is actually used, due to the terrain at the site, the laying of the pipeline will also cause certain bends. However, the above pipeline is not convenient for bending, which will cause the installation of the drainage pipeline to deviate, resulting in an unstable installation of the drainage pipeline.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0025] An embodiment of the present application discloses a new type of bendable stainless steel corrugated flange gas drainage pipeline, which includes a stainless steel corrugated pipe 1. Both ends of the stainless steel corrugated pipe 1 are fixedly connected with connection mechanisms; the connection mechanism includes a first flange 2. One side of the first flange 2 is fixedly connected with one end of the stainless steel corrugated pipe 1. A plurality of screws 3 are movably connected to the outside of the first flange 2. The plurality of screws 3 are annularly arranged outside the first flange 2. Two rotating rods 4 are fixedly connected to the outside of the first flange 2. The two rotating rods 4 are symmetrically arranged outside the first flange 2. A rotating block 5 is movably connected to the outside of the rotating rod 4. Two rivets 6 are inserted into the outside of the rotating block 5. One side of the rotating block 5 is fixedly connected with an arc-shaped clamping plate 7. A clamping plate 8 is movably connected to the outside of the arc-shaped clamping plate 7. A limiting block 9 is fixedly connected to one side of the clamping plate 8. Two sealing rings 10 are fixedly installed on the other side of the first flange 2; two connecting heads 11 are arranged on the outside of the stainless steel corrugated pipe 1. One side of the connecting head 11 is fixedly connected with a second flange 12. Two card slots 13 are opened on one side of the second flange 12. After the first flange 2 and the second flange 12 are aligned, the connection between the first flange 2 and the second flange 12 can be positioned to a certain extent by rotating the two arc-shaped clamping plates 7, avoiding the deviation of the first flange 2 and the second flange 12 during subsequent screw tightening, and at the same time, keeping the edge connection of the first flange 2 and the second flange 12 stable.

[0026] Refer to Figure 5 As shown in the figure, two support mechanisms are arranged on the outside of the stainless steel corrugated pipe 1. The support structure includes a positioning ring 14. The inner wall of the positioning ring 14 is movably connected to the outside of the stainless steel corrugated pipe 1. A rotating seat 15 is fixedly connected to the bottom of the positioning ring 14. A plug rod 16 is movably connected inside the rotating seat 15. The two rotating seats 15 and the plug rod 16 can position the stainless steel corrugated pipe 1 and the wall.

[0027] Refer to Figure 6As shown, there are shells 17 fixedly connected inside both positioning rings 14. The two shells 17 are symmetrically arranged on both sides of the positioning ring 14. A button 18 is sleeved inside the shell 17. A multi-tooth clamping plate 19 is fixedly connected to the inner wall of the shell 17. A tooth clamping push plate 20 is inserted into one side of the multi-tooth clamping plate 19. A spring 21 is arranged outside the tooth clamping push plate 20. A push rod 22 is fixedly connected to one side of the multi-tooth clamping plate 19. One end of the push rod 22 is fixedly connected to a clamping ring 23. By pressing the two buttons 18, the tooth clamping push plate 20 can be pushed to slide on one side of the multi-tooth clamping plate 19, so that the tooth clamping push plate 20 can be pushed by the spring 21 to be clamped with the clamping opening at one end of the multi-tooth clamping plate 19. After the two positioning rings 14 are moved to appropriate positions, the positioning rings 14 can be quickly fixed to the outer side of the stainless steel corrugated pipe 1, facilitating stable support and fixation of the bent stainless steel corrugated pipe 1.

[0028] The working principle of the present utility model: Before discharging gas in the mine tunnel, first connect the stainless steel corrugated pipe 1 with the two connectors 11. First, align one end of the stainless steel corrugated pipe 1, the first flange 2, with the corresponding connector 11, so that the two rotating rods 4 on one side of the first flange 2 can be inserted into the two holes on the surface of the second flange 12. After that, when the first flange 2 and the second flange 12 are aligned, rotate the two arc-shaped clamping plates 7 around the corresponding rotating rods 4 through the two rotating blocks 5, so that the two arc-shaped clamping plates 7 can clamp the outer sides of the first flange 2 and the second flange 12, enabling the first flange 2 and the second flange 12 to be quickly aligned and remain stable without easy deviation. Then, insert multiple screws 3 into the corresponding jacks of the first flange 2 and the second flange 12 to stably connect the first flange 2 and the second flange 12 with screws. At the same time, the two sealing rings 10 on one side of the first flange 2 coincide with the two clamping grooves 13 on one side of the second flange 12, ensuring the stable connection between the first flange 2 and the second flange 12.

[0029] After that, according to the actual usage scenario, the stainless steel corrugated pipe 1 can be bent. Then, press the two buttons 18 on the outer sides of the two positioning rings 14. The two buttons 18 push the tooth clamping push plate 20 to compress the spring 21. Then, the two clamping rods on both sides of the button 18 push against the inclined surface on one side of the tooth clamping push plate 20, enabling the tooth clamping push plate 20 to be pushed by the spring 21, so that the spring 21 can support at the tooth part of the multi-tooth clamping plate 19, and the tooth clamping push plate 20 can push the push rod 22 and the clamping ring 23 to clamp the outer wall of the stainless steel corrugated pipe 1. After the stainless steel corrugated pipe 1 is bent, it can be limited by the two positioning rings 14, enabling the stainless steel corrugated pipe 1 to be stably fixed after being bent.
