Description

Technical Field

[0001] This utility model relates to the field of reinforced spiral welded pipe technology, specifically a reinforced spiral welded pipe for gas drainage. Background Technology

[0002] Currently, most gas drainage spiral welded pipes on the market use ordinary carbon steel cold-galvanized flanges welded to both ends of the pipe for connection. This method has the following disadvantages: the flanges are expensive and relatively heavy, which increases the handling intensity during construction and adds welding steps. In particular, the welding position of stainless steel reinforced spiral welded pipes will have a heat-affected zone, which will reduce the corrosion resistance and strength of the local area. Therefore, in order to solve the existing problems, a reinforced spiral welded pipe for gas drainage has been designed.

[0003] In the current use of reinforced spiral welded pipes, the two sides of the reinforced spiral welded pipes are usually connected by bolts. This connection method requires a large number of bolts, and each bolt and nut needs to be rotated a large number of times to fix the two sides of the reinforced spiral welded pipes. This makes the connection operation of the two sides of the reinforced spiral welded pipes cumbersome and inconvenient.

[0004] Meanwhile, during the use of existing reinforced spiral welded pipes, due to the poor buffering performance of the outer side of the pipe, the pipe is easily deformed and cracked when subjected to impact or pressure from external objects, resulting in damage and affecting its service life. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of inconvenience in connecting the two sides of the reinforced spiral welded pipe and the problem that the main body of the reinforced spiral welded pipe is easily damaged by the impact of external objects, and to propose a reinforced spiral welded pipe for gas drainage.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] Design a reinforced spiral welded pipe for gas extraction, including a reinforced spiral welded pipe body and a sealing gasket. The two ends of the sealing gasket are respectively abutted against the two sides of the reinforced spiral welded pipe body. A connecting assembly is provided on the right side of the left side of the reinforced spiral welded pipe body. The connecting assembly includes abutting blocks. The outer ends of the abutting blocks on both sides are abutted against the left side of the reinforced spiral welded pipe body. The inner side of the abutting blocks is abutted against a moving block. The middle part of the moving block is fixedly connected to a pull rod. The right side of the moving block is fixedly connected to one end of a spring. The front end of the abutting block is fixedly connected to one end of a torsion spring.

[0008] Preferably, the other end of the torsion spring is fixedly connected to the connecting seat, and the middle part of the abutting block is rotatably connected to the connecting seat.

[0009] Preferably, the other end of the spring is fixedly connected to the connecting seat, and the outer wall of the pull rod is slidably connected to the connecting seat.

[0010] Preferably, multiple connecting seats are attached to the outer sides of the reinforcing spiral welded pipe body on both sides, and the outer side of the sealing gasket is pressed against the multiple connecting seats.

[0011] Preferably, the outer wall of the reinforcing spiral welded pipe body is provided with a protective structure, the protective structure including an inner protective component, the outer wall of the inner protective component being bonded to the reinforcing spiral welded pipe body, and the outer wall of the inner protective component being bonded to the outer protective component.

[0012] The present invention discloses a reinforced spiral welded pipe for gas extraction, which has the following advantages: when the pull rod is pulled to the right, the pull rod drives the moving block to move to the right. At the same time, the moving block compresses the spring and disengages from the clamping block. This causes the spring force to drive the clamping block to rotate inward. Then, the connecting seat passes through the connecting holes of the reinforced spiral welded pipe body and the sealing gasket on both sides. After releasing the pull rod, the spring force pushes the clamping block to return to its original position, so that the clamping block abuts against the cone of the reinforced spiral welded pipe on the left side, thereby connecting the reinforced spiral welded pipe bodies on both sides. This method makes it more convenient to connect the reinforced spiral welded pipe bodies on both sides.

[0013] The outer protective component is made of nitrile rubber, which has excellent wear resistance. Rubber also has good elasticity, which cushions the impact and compression from external objects, reducing friction between the reinforced spiral welded pipe body and the outside. The inner protective component is made of silicone rubber, which has excellent aging resistance and high elasticity, thus buffering the impact or pressure on the reinforced spiral welded pipe body and preventing damage from impacts from external objects, thereby improving the service life of the reinforced spiral welded pipe body.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1:

[0021] See attached document Figure 1-4 In this embodiment, a reinforced spiral welded pipe for gas drainage includes a reinforced spiral welded pipe body 1 and a sealing gasket 2. The two ends of the sealing gasket 2 abut against the two sides of the reinforced spiral welded pipe body 1. A connecting component 4 is provided on the right side of the left reinforced spiral welded pipe body 1. The connecting component 4 includes abutting blocks 4a4, such as... Figure 2 and Figure 3 As shown, the torsion spring 4a5 is in a deformed state when the user pulls the lever 4a1 to the right;

[0022] Pull rod 4a1 drives moving block 4a2 to move to the right. While moving block 4a2 compresses spring 4a3, moving block 4a2 disengages from pressing block 4a4, causing the elastic force of torsion spring 4a5 to drive pressing block 4a4 to rotate inward. The outer ends of both pressing blocks 4a4 abut against the left reinforcing spiral welded pipe body 1. The inner side of pressing block 4a4 abuts against moving block 4a2. The middle part of moving block 4a2 is fixedly connected to pull rod 4a1. The right side of moving block 4a2 is fixedly connected to one end of spring 4a3. The front end of pressing block 4a4 is fixedly connected to one end of torsion spring 4a5.

[0023] The other end of the torsion spring 4a5 is fixedly connected to the connecting seat 5, and the middle part of the clamping block 4a4 is rotatably connected to the connecting seat 5.

[0024] The other end of spring 4a3 is fixedly connected to connecting seat 5, and the outer wall of pull rod 4a1 is slidably connected to connecting seat 5, such as... Figure 2 and Figure 3 The spring 4a3 shown is still in a compressed state, so that the elastic force of the spring 4a3 always presses against the pressing block 4a4 through the moving block 4a2, so that the pressing block 4a4 presses against the main body 1 of the reinforced spiral welded pipe.

[0025] Multiple connecting seats 5 are attached to the outer side of the spiral welded pipe body 1 with two reinforcing ribs on both sides, and the outer side of the sealing gasket 2 is pressed against the multiple connecting seats 5.

[0026] The outer wall of the reinforced spiral welded pipe body 1 is provided with a protective structure 3. The protective structure 3 includes an inner protective component 302. The outer protective component 302 is made of nitrile rubber, which has excellent wear resistance. Rubber also has good elasticity, which buffers the impact and compression of external objects and reduces the friction between the reinforced spiral welded pipe body 1 and the outside. The inner protective component 302 is made of silicone rubber, which has excellent aging resistance and high elasticity, thus buffering the impact or pressure generated on the reinforced spiral welded pipe body 1. The outer wall of the inner protective component 302 is bonded to the reinforced spiral welded pipe body 1, and the outer wall of the inner protective component 302 is bonded to the outer protective component 301.

[0027] Working principle:

[0028] First, when connecting the reinforced spiral welded pipes for gas drainage operations, the two sides of the reinforced spiral welded pipe body 1 are joined together, and the sealing gasket 2 is placed between the two sides of the reinforced spiral welded pipe body 1.

[0029] Then, when the user pulls the lever 4a1 to the right, the lever 4a1 drives the moving block 4a2 to move to the right. At the same time, the moving block 4a2 compresses the spring 4a3 and disengages from the clamping block 4a4. This causes the spring force of the torsion spring 4a5 to drive the clamping block 4a4 to rotate inward. Then, the connecting seat 5 passes through the connecting holes of the reinforcing spiral welded pipe body 1 and the sealing gasket 2 on both sides. Then, the lever 4a1 is released, and the spring force of the spring 4a3 pushes the clamping block 4a4 to return to its original position, so that the clamping block 4a4 abuts against the reinforcing spiral welded pipe cone 1 on the left side, thereby connecting the reinforcing spiral welded pipe body 1 on both sides. This method makes it more convenient to connect the reinforcing spiral welded pipe body 1 on both sides.

[0030] The outer protective component 302 is made of nitrile rubber, which has excellent wear resistance. Rubber also has good elasticity, which cushions the impact and compression from external objects and reduces friction between the reinforced spiral welded pipe body 1 and the outside. The inner protective component 302 is made of silicone rubber, which has excellent aging resistance and high elasticity, thus cushioning the impact or pressure on the reinforced spiral welded pipe body 1 and preventing damage from impacts from external objects.

[0031] Example 2:

[0032] See attached document Figure 1-4In this embodiment, a reinforced spiral welded pipe for gas extraction is provided, wherein the connecting component 4 may further include a slider 4b1, the inner ends of both sliders 4b1 are slidably connected to the moving block 4a2, and the outer walls of the sliders 4b1 are slidably connected to the connecting seat 5. The restriction between the sliders 4b1 and the grooves of the connecting seat 5 prevents the pull rod 4a1 from causing the moving block 4a2 to deflect during the pulling process.

[0033] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
