Description

Technical Field

[0001] The invention relates to the field of pipeline processing, in particular to a processing device for an anti-corrosion pressure pipeline. Background Art

[0002] In the prior art, anti-corrosion pressure pipes are generally plastic-lined composite steel pipes, that is, anti-corrosion plastic powder is applied to the inside of the pipe and plastic is applied to the flange sealing surface to achieve the anti-corrosion performance of the pipe. When processing the inner plastic lining layer of the elbow, plastic powder is often manually filled into the pre-heated inner space of the steel pipe, and the flange sealing surface is covered with a pressing plate after the powder is applied. After cooling, the pressing plate is removed. Because the formed lining plastic will adhere to the pressing plate and be taken off when it is removed, the paint is applied to the flange sealing surface again until the flange sealing surface is evenly covered with the lining plastic, and finally the excess plastic powder that is not adhered to the pipe wall is swept out.

[0003] Since the pipe to be lined with plastic has a curvature, the plastic powder is easy to fall onto the outer wall of the pipe and into the flange hole when filling the plastic powder and sweeping out the excess powder, and needs to be removed later.

[0004] The information disclosed in the background technology section of this application is only intended to deepen the understanding of the general background technology of this application, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Summary of the invention

The sliding member moves equidistantly in the radial direction of a circle with the base point as the center; there is a gap between the flanges of two adjacent bent pipes, and the movement of the sliding member is used to shorten the distance between the flanges of two adjacent bent pipes, so as to extrude the liner.

[0010] Optionally, a transmission assembly is further included, wherein the transmission assembly is connected to the sliding member, and the transmission assembly is used to enable the sliding member to move equidistantly.

[0043] like Figures 1 to 11As shown, the present invention provides an anti-corrosion pressure pipe processing equipment, including a frame assembly 100, a clamping assembly 300 and a motor 500. The frame assembly 100 is fixedly connected to the output end of the motor 500, and the rotation of the motor 500 drives the frame assembly 100 to rotate. The clamping assembly 300 is arranged on the frame assembly 100 and is used to clamp the pipe to be processed.

[0044] It should be added that the processing equipment for the corrosion-resistant pressure pipeline of the present invention is used to process multiple pipelines at the same time. The pipe group 200 required includes a bend 210 and a liner 220. The processing purpose is to line the inner wall surface and flange sealing surface of the bend 210 with plastic; a flange is welded on the end face of the bend 210, and there is a gap between the flange surfaces of two adjacent bends 210. A liner 220 is inserted between two adjacent bends 210, and the end of the liner 220 is inserted into the inner wall surface of the bend 210. The plastic powder required for the lining is filled in the pipeline space surrounded by the bend 210 and the liner 220.

[0045] It should also be added that the processing equipment for the anti-corrosion pressure pipeline of the present invention also includes a counterweight box 600, the motor 500 is arranged on the counterweight box 600, and the counterweight box 600 is arranged on the ground.

[0046] The frame assembly 100 includes a frame 110 and a sliding member 120. The frame 110 is fixedly connected to the output end of the motor 500. A rotating shaft is arranged on the frame 110, and the rotating shaft is arranged in the horizontal direction. The output end of the motor 500 corresponds to the rotating shaft, so that the frame 110 rotates. The sliding member 120 is slidably arranged on the frame 110, and there are at least two sliding members 120. A base point 130 is arranged on the frame 110, and a slide groove 111 is also arranged on the frame 110. The slide groove 111 is arranged at equal angles and equal distances around the base point 130, and the sliding member 120 is slidably arranged in the slide groove 111. The clamping assembly 300 is arranged on the sliding member 120, and is used to clamp the bent pipe 210 to be processed. The clamping assembly 300 is evenly arranged along the circumference, and the liner 220 is inserted between two adjacent bent pipes 210. When multiple sliding members 120 are simultaneously moved toward the direction approaching the base point 130, the elbow 210 clamped on the sliding member 120 moves toward the base point 130 along the radial direction of the circle with the base point 130 as the center, and the liner 220 inserted between two adjacent elbows 210 is squeezed until it is attached to the flange sealing surface of the elbow 210.

[0047] When in use, the pre-heated bent pipe 210 is clamped on the sliding member 120 through the clamping assembly 300, and the liner 220 is inserted between two adjacent bent pipes 210. At the same time, the plastic powder is filled into the space enclosed by the bent pipe 210 and the liner 220. The motor 500 is started to rotate forward first and then reversely, so that the frame 110 rotates a certain number of times in a clockwise direction and then a certain number of times in a counterclockwise direction, so that the plastic powder is evenly adhered to the inner wall of the bent pipe 210. At this time, the outer wall of the liner 220 is heated. After heating, the sliding member 120 is moved simultaneously to make it move along the slide groove 111 toward the base point 130 until the liner 220 is pressed against the flange sealing surfaces of the two adjacent bent pipes 210 and cooled to form. The inner wall lining and flange sealing surface plastic coating processing of the bent pipe 210 are completed. Subsequently, the middle portion of the extruded liner 220 is evenly cut into two parts along a direction parallel to the flange sealing surface of the elbow 210, so as to obtain the finished elbow 210. Fig.11 shown.

[0048] It should be supplemented that the central angle corresponding to the axis of rotation of the elbow 210 is consistent with the angle between two adjacent slide grooves 111. In the present embodiment, the elbow 210 is a 90° elbow, and the slide grooves 111 are provided in four numbers, and the angle between two adjacent slide grooves 111 is 90°. There are four sliding members 120, and the processing equipment for the anti-corrosion pressure pipe of the present invention can process four anti-corrosion pressure pipes at the same time.

[0049] It is also necessary to refer to Fig.10 The liner 220 is a plastic pipe made of the same material as the plastic powder used for lining the inner wall of the elbow 210. Notches 221 are provided at both ends of the liner 220. The notches 221 facilitate the insertion of the liner 220 into the elbow 210. The notches 221 are conducive to the hot-melt adhesion of the plastic powder in the pipe and the notches 221 during the processing, thereby improving the tightness of the connection between the anti-corrosion lining at the flange and the anti-corrosion lining in the pipe; a V-shaped notch 222 is provided in the middle of the liner 220. The V-shaped notch 222 causes the liner 220 to begin to deform and bulge in the middle of the liner 220 when it is squeezed. At the same time, during the rotation of the elbow 210, the guiding trend of the V-shaped notch 222 makes the inner wall of the elbow 210 that is not easily contacted with the plastic powder evenly adhered.

[0050] In one embodiment, multiple sliders 120 are moved simultaneously by manual direct contact.

[0051] In another embodiment, please refer to Figures 1 to 5 The processing equipment for the anti-corrosion pressure pipe of the present invention further includes a transmission assembly 400, which is disposed on the frame 110, and the transmission assembly 400 is slidably connected to the sliding member 120, and the transmission assembly 400 drives the sliding member 120 to make multiple sliding members 120 move simultaneously.

[0052] In a further embodiment, the transmission assembly 400 includes a first transmission member 410 , which rotates around the base point 130 ; the first transmission member 410 is provided with an arc notch 411 , which is slidably connected and corresponds to the sliding member 120 .

[0053] In a further embodiment, the arc slot 411 is arranged at equal angles and at equal distances around the base point 130, and the two ends of the arc slot 411 are semi-circular arc surfaces. The two semi-circular arc surfaces are connected and tangent to the two arc surfaces arranged therebetween, so that the two semi-circular arc surfaces and the two arc surfaces form a complete arc slot 411; the distances between the centers of the two semi-circular arc surfaces of the arc slot 411 and the base point 130 are not equal, and there is an angle between the centers of the two semi-circular arc surfaces of the arc slot 411 and the line connecting the base point 130, that is, the arc slot 411 has an intersection with the radial direction of the circle with the base point 130 as the center. A column 121 is provided on the sliding member 120, and the column 121 is slidably connected with the arc groove 411. When the first transmission member 410 rotates around the base point 130, the arc groove 411 on the first transmission member 410 is driven to rotate, and the column 121 slides in the arc groove 411. Because the sliding member 120 is set in a fixed slide groove 111, the column 121 drives the sliding member 120 to slide in the slide groove 111. When the first transmission member 410 rotates, multiple sliding members 120 simultaneously make equidistant sliding along the slide groove 111 and in the vertical direction close to the base point 130, so as to achieve equidistant reduction of the distance between multiple elbows 210, and the liner 220 is squeezed and bulged until it is pressed on the flange sealing surface of two adjacent elbows 210 plugged with the liner 220. Figure 8 and Fig. 9 shown.

[0054] In a further embodiment, Figure 3 and Figure 4 As shown, a first shaft 112 is provided at a position of the frame 110 corresponding to the base point 130 , and a first through hole 412 is provided at a position of the first transmission member 410 corresponding to the base point 130 . When the first through hole 412 cooperates with the first shaft 112 , the first transmission member 410 is rotatably provided on the frame 110 .

[0055] In a further embodiment, Figure 3 and Figure 4 As shown, the transmission assembly 400 also includes a second transmission member 420, the first transmission member 410 and the second transmission member 420 are a pair of meshing gears, a second through hole 421 is arranged on the second transmission member 420, and a second shaft 113 is also arranged on the frame 110. The second through hole 421 cooperates with the second shaft 113 so that the second transmission member 420 can be rotatably arranged on the frame 110, and a handle 422 is arranged on the second transmission member 420; when the handle 422 is turned, the second transmission member 420 drives the first transmission member 410 to rotate.

[0056] In a further embodiment, Figure 1 and Figure 3 As shown, the transmission assembly 400 further includes a cover plate 430 , which is disposed on the frame 110 to protect the first transmission member 410 and the second transmission member 420 .

[0057] In combination with the above embodiments, the use principle and working process of the present invention are as follows:

[0058] The overall working process steps are: Figure 4-Figure 6 - Figure 8 As shown, Figure 4 The liner 220 is inserted between a pair of adjacent flange sealing surfaces of the two adjacent bent pipes 210. For the structure of the liner 220, please refer to Fig.10 , during the process of inserting the liner 220, the plastic powder is filled into the space enclosed by the multiple elbows 210 and the multiple liner 220. After the pipe group 200 is installed, the motor 500 is started to make the output end of the motor 500 rotate forward first, and the frame 110 rotates clockwise in the vertical direction first; after the frame 110 rotates a certain number of times, the output end of the motor 500 is reversed, and the frame 110 rotates a certain number of times counterclockwise, and then the motor 500 is turned off. In this process, the rotation of the frame 110 drives the sliding member 120 to rotate, and the pipe group 200 clamped on the sliding member 120 is also driven to rotate in the vertical direction. The plastic powder in the pipe group 200 is evenly adhered to the inner wall of the elbow 210, and the notch 221 of the liner 220 is thermoplastically bonded to the plastic powder to form a whole;

[0059] Please refer to Figures 6 to 9 , after turning off the motor 500, the outer wall of the liner 220 is heated. After heating, the handle 422 is turned counterclockwise, and the second transmission member 420 rotates counterclockwise around the second shaft 113, and the second transmission member 420 is meshed with the first transmission member 410, and the second transmission member 420 drives the first transmission member 410 to rotate clockwise around the first shaft 112; when the first transmission member 410 rotates, the arc notch 411 rotates, and the column 121 slidably connected to the arc notch 411 slides in the arc notch 411, and the column 121 drives the sliding member 120 to move close to the base point 130 in the slide groove 111, and the curved pipe 210 on the sliding member 120 makes an equidistant movement close to the base point 130 in the vertical direction; during the movement, the distance between the two adjacent curved pipes 210 becomes smaller, and the pressure in the pipe group 200 increases. In addition, because the V-shaped notch 222 is set in the middle of the liner 220, the liner 220 will be squeezed and bulge from the middle, such as Figure 6 Continue to rotate the handle 422 until the liner 220 is completely pressed against the flange sealing surface of the elbow 210, as shown Figure 8 As shown, the plastic coating process of the flange sealing surface of the elbow 210 has been completed. The liner 220 is evenly cut from the middle of the liner 220 in a direction parallel to the flange sealing surface. Then, the flange sealing surface and the inner wall of each elbow 210 are coated with plastic. The processed workpiece is as shown in FIG. Fig.11 shown.

[0060] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-described embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present application.
