Abstract

The present invention relates to the technical field of pipeline production equipment, and specifically to a pipeline production equipment lined with anti-corrosion materials, which includes a bracket, a support block, a traction member and a clamping sleeve. First, the spacing between the clamping sleeve and the support block is adjusted to ensure that one end of the anti-corrosion pipe can be sleeved on the outside of the support block, and one end of the anti-corrosion pipe can enter the inside of the clamping sleeve, and then the anti-corrosion pipe is heated. The anti-corrosion pipe can be deformed after heating. At this time, under the action of the first elastic member, the clamping sleeve is made to approach the support block, and the clamping sleeve and the support block clamp the anti-corrosion pipe together. As the traction member pulls the support block, the support block and the clamping sleeve enter the metal pipe together, and the friction between the support block and the anti-corrosion pipe increases, further increasing the stability of the traction anti-corrosion pipe. At the same time, when the clamping sleeve slides along the axis of the metal pipe, the outer wall of the clamping sleeve can grind the inner wall of the metal pipe to prevent impurities on the inner wall of the metal pipe from damaging the anti-corrosion pipe.

[0002] Pipeline anti-corrosion refers to measures to slow down or prevent the corrosion and deterioration of pipelines under the chemical and electrochemical effects of internal and external media or the metabolic activities of microorganisms. When producing anti-corrosion pipelines, anti-corrosion pipes are generally added inside metal pipes. During the processing, the anti-corrosion pipes are generally inserted into the metal pipes with the help of mechanical production equipment. In existing production equipment, the anti-corrosion pipe is inserted into the metal pipe by pulling with a traction cylinder to achieve the installation of the anti-corrosion pipe inside the metal pipe. However, during the process of pipe insertion, the inner wall of the metal pipe and the outer wall of the anti-corrosion pipe are severely rubbed. If there are impurities on the inner wall of the metal pipe, the impurities on the inner wall of the metal pipe will damage the outer wall of the anti-corrosion pipe, thereby affecting the anti-corrosion performance of the anti-corrosion pipe.

[0028] like Figures 1 to 6 As shown, an embodiment of the present invention provides a pipeline production device lined with anti-corrosion materials, including a bracket 110, a support block 140, a traction member and a clamping sleeve 150.

[0029] The bracket 110 has a horizontal mounting surface, the length direction of the mounting surface is placed in the left-right direction, the bracket 110 is fixedly provided with a metal pipe 120, and the axial direction of the metal pipe 120 is consistent with the length direction of the mounting surface. The bracket 110 is provided with an anti-corrosion pipe 130 coaxial with the metal pipe 120, the anti-corrosion pipe 130 is provided on one side of the metal pipe 120, and the anti-corrosion pipe 130 can move along its own axial direction, and the outer diameter of the anti-corrosion pipe 130 is equal to the inner diameter of the metal pipe 120, so the anti-corrosion pipe 130 can enter the interior of the metal pipe 120.

[0030] The support block 140 can enter the interior of the anti-corrosion tube 130, and the anti-corrosion tube 130 can fit the outer wall of the support block 140 after being heated. When the anti-corrosion tube 130 needs to be installed inside the metal tube 120, the support block 140 is placed on the end of the anti-corrosion tube 130 close to the metal tube 120, and the end of the anti-corrosion tube 130 close to the metal tube 120 is heated. The heated anti-corrosion tube 130 can shrink, and the heated anti-corrosion tube 130 can fit on the outside of the support block 140, making it easier for one end of the anti-corrosion tube 130 to be inserted into the interior of the metal tube 120.

[0031] The traction member can pull the support block 140 to move along the axial direction of the metal tube 120. When the traction member pulls the support block 140, the friction between the support block 140 and the anti-corrosion tube 130 increases. When one end of the anti-corrosion tube 130 close to the metal tube 120 is attached to the outside of the support block 140, the traction member is started. The traction member moves the support block 140 and the end of the anti-corrosion tube 130 to the inside of the metal tube 120 synchronously. When the traction member pulls the support block 140, the friction between the support block 140 and the anti-corrosion tube 130 increases, preventing the support block 140 from detaching from the anti-corrosion tube 130.

[0032] The clamping sleeve 150 is spaced apart from the support block 140. When the anti-corrosion pipe 130 is not attached to the support block 140, the distance between the clamping sleeve 150 and the support block 140 is at its farthest. A first elastic member is disposed between the clamping sleeve 150 and the support block 140. When one end of the anti-corrosion pipe 130 is attached to the outer wall of the support block 140, the first elastic member can drive the clamping sleeve 150 to approach the support block 140. The clamping sleeve 150 can clamp the anti-corrosion pipe 130 together with the support block 140, further increasing the stability between the support block 140 and the anti-corrosion pipe 130. The outer wall of the clamping sleeve 150 can tightly abut the inner wall of the metal pipe 120. When the traction member pulls the support block 140, the clamping sleeve 150 can slide along the axis of the metal pipe 120. The outer wall of the clamping sleeve 150 can grind the inner wall of the metal pipe 120. By grinding the inner wall of the metal pipe 120 by the clamping sleeve 150, impurities on the inner surface of the metal pipe 120 are reduced, and the probability of the outer wall of the anti-corrosion pipe 130 being damaged is reduced.

[0033] The present invention provides a pipeline production device lined with an anti-corrosion material. The metal pipe 120 is fixed on a bracket 110. When the anti-corrosion pipe 130 needs to be installed inside the metal pipe 120, the distance between the clamping sleeve 150 and the support block 140 is first adjusted to ensure that one end of the anti-corrosion pipe 130 can be sleeved on the outside of the support block 140 and one end of the anti-corrosion pipe 130 can enter the clamping sleeve 150. Then, the anti-corrosion pipe 130 is heated. After heating, the anti-corrosion pipe 130 can be deformed. At this time, under the action of the first elastic member, the clamping sleeve 150 is moved toward the support block 140. As the traction member pulls the support block 140, the support block 140 and the clamping sleeve 150 enter the interior of the metal tube 120 together. The friction between the support block 140 and the anti-corrosion tube 130 increases, further increasing the stability of the traction of the anti-corrosion tube 130. At the same time, when the clamping sleeve 150 slides along the axis of the metal tube 120, the outer wall of the clamping sleeve 150 can grind the inner wall of the metal tube 120 to prevent impurities on the inner wall of the metal tube 120 from damaging the anti-corrosion tube 130.

[0034] In one embodiment, the traction member includes a traction rod 170 and a traction cylinder 160. The traction rod 170 is coaxially arranged with the metal tube 120, and the traction rod 170 is connected with the support block 140. The traction rod 170 can move on the bracket 110 along the axial direction of the metal tube 120. The traction cylinder 160 is fixedly arranged on the bracket 110, and the power output shaft of the traction cylinder 160 is coaxially fixedly connected with the traction rod 170. In the initial state, the metal tube 120 is outside the traction rod 170, and the length of the traction cylinder 160 is in the longest state. When the anti-corrosion tube 130 is attached to the support block 140, the traction cylinder 160 is controlled to be gradually shortened, and the traction cylinder 160 drives the traction rod 170 to gradually withdraw from the metal tube 120, so that the anti-corrosion tube 130 gradually enters the inside of the metal tube 120.

[0035] In one embodiment, the outer peripheral wall of the support block 140 is provided with a plurality of mounting grooves, the plurality of mounting grooves are evenly distributed around the circumference direction of the support block 140, and the mounting grooves are arranged along the length direction of the support block 140. A tension rod 210 is arranged in each mounting groove, and in the initial state, the tension rod 210 is completely in the mounting groove, and when the traction rod 170 pulls the support block 140 to move, the plurality of tension rods 210 simultaneously tension the inner side wall of the anti-corrosion pipe 130, so that the tension force between the support block 140 and the inner side wall of the anti-corrosion pipe 130 is increased, and the anti-corrosion pipe 130 is further prevented from being out of contact with the support block 140.

[0036] In one embodiment, a limiting groove is provided on the support block 140, and a limiting block is provided on the traction rod 170, and the limiting block is slidably provided in the limiting groove. Specifically, a plug-in groove is provided on the support block 140, and the plug-in groove is coaxially provided with the support block 140. One end of the traction rod 170 can be inserted into the plug-in groove, and one end of the traction rod 170 can slide in the plug-in groove. The limiting groove is provided on the inner side wall of the plug-in groove, and the length direction of the limiting groove is parallel to the axial direction of the support block 140. The limiting block is provided on the side wall of the traction rod 170, and the limiting block is always in the limiting groove. A transmission member is provided between the traction rod 170 and each of the tension rods 210, and the transmission member is used to drive the tension rod 210 to tighten the inner side wall of the anti-corrosion pipe 130 when the limiting block on the traction rod 170 moves along the limiting groove. By providing the transmission member, the drive of the tension rod 210 by providing an independent driving source can be reduced, thereby reducing the cost of the device.

[0037] In one embodiment, the transmission member includes a transmission rod 220 and a second elastic member, the transmission rod 220 is fixedly connected to the end of the tightening rod 210, and the connection between the transmission rod 220 and the tightening rod 210 is rotatably connected to the support block 140; in this embodiment, the limit groove is connected to the plug-in groove, the transmission rod 220 extends along the radial direction of the support block 140, and the end of the transmission rod 220 away from the axis of the support block 140 is fixedly connected to the end of the tightening rod 210, so that a fixed angle is formed between the transmission rod 220 and the tightening rod 210, and the end of the transmission rod 220 fixedly connected to the tightening rod 210 is rotatably connected to the support block 140, so that both the transmission rod 220 and the tightening rod 210 can be deflected on the support block 140. The second elastic member is arranged between the end of the transmission rod 220 and the end of the traction rod 170. When the limit block on the traction rod 170 moves along the limit groove, the second elastic member can accumulate force so that the tightening rod 210 can tighten the inner wall of the anti-corrosion pipe 130. In this embodiment, the second elastic member is a second spring, one end of the second spring is fixedly connected to the end of the transmission rod 220 away from the tightening rod 210, and the other end of the second spring is fixedly connected to the end of the traction rod 170. In the initial state, the tightening rod 210 is completely in the installation groove, and the second spring is in the original length state. As the traction cylinder 160 is shortened, the limit block on the traction rod 170 slides along the limit groove, and the second spring gradually begins to accumulate force. Under the traction of the second spring, the transmission rod 220 and the tightening rod 210 are both deflected on the support block 140, and the tightening rod 210 gradually tightens against the inner wall of the anti-corrosion pipe 130.

[0038] In one of the embodiments, a one-way member is provided in the limit groove, and the one-way member is used to prevent the limit block from sliding back and forth in the limit groove. Specifically, the one-way member includes a one-way rack and an elastic claw, wherein the one-way rack is fixedly provided in the limit groove, and the length direction of the one-way rack is consistent with the length direction of the limit groove, and the elastic claw is provided on the limit block, and the elastic claw is always engaged with the one-way rack. By setting the direction of the one-way rack, the limit block on the traction rod 170 can slide along the limit groove when the traction cylinder 160 is shortened, preventing the second spring from driving the limit block to automatically reset, thereby ensuring that the anti-corrosion pipe 130 can stably enter the interior of the steel pipe.

[0039] In one of the embodiments, the clamping sleeve 150 can slide on the traction rod 170, and the clamping sleeve 150 can rotate on the traction rod 170. When the clamping sleeve 150 slides inside the metal tube 120, the clamping sleeve 150 rotates. When the clamping sleeve 150 rotates, the outer wall of the clamping sleeve 150 can clean the impurities on the inner wall of the metal tube 120 to prevent the impurities on the inner wall of the metal tube 120 from damaging the outer wall of the anti-corrosion tube 130.

[0040] In one of the embodiments, the clamping sleeve 150 can be deformed, and a plurality of spiral grooves 151 are provided on the clamping sleeve 150. The plurality of spiral grooves 151 on the clamping sleeve 150 are evenly distributed along the circumferential direction of the clamping sleeve 150, and impurities on the inner wall of the metal tube 120 can enter the spiral grooves 151. By providing the spiral grooves 151, when the clamping sleeve 150 slides along the axial direction of the metal tube 120, and when the impurities on the inner wall of the metal tube 120 enter the spiral grooves 151, the clamping sleeve 150 rotates under the guidance of the spiral grooves 151, and the rotation of the clamping sleeve 150 inside the metal tube 120 can clean up the impurities on the inner wall of the metal tube 120.

[0041] In one of the embodiments, the inner wall and the outer wall of the clamping sleeve 150 are both set to rough surfaces. When the clamping sleeve 150 rotates, the inner wall of the clamping sleeve 150 can grind the outer wall of the anti-corrosion tube 130. After the outer wall of the anti-corrosion tube 130 is grinded, it is convenient to fix the anti-corrosion tube 130 on the metal tube 120. Specifically, when the anti-corrosion tube 130 is fully inserted into the metal tube 120, it is necessary to fix the anti-corrosion tube 130 and the metal tube 120. Generally, the length of the anti-corrosion tube 130 is set to be greater than the length of the metal tube 120, and the end of the anti-corrosion tube 130 is on the outside of the end of the metal tube 120. When fixing the anti-corrosion tube 130 and the metal tube 120, the anti-corrosion tube 130 on the outside of the metal tube 120 is turned outward so that the outer wall of the anti-corrosion tube 130 can fit the metal tube 120. After the outer wall of the anti-corrosion tube 130 is grinded, it is convenient to fit the anti-corrosion tube 130 and the metal tube 120.

[0042] In one of the embodiments, a slide groove is provided on the traction rod 170, and the slide groove is provided along the radial direction of the traction rod 170. A stopper is slidingly provided in the slide groove, and the stopper can hinder the sliding of the clamping sleeve 150 on the traction rod 170. In the initial state, the stopper is in a state of hindering the sliding of the clamping sleeve 150 along the traction rod 170. At this time, the first elastic member is in a force storage state. Specifically, the first elastic member is a first spring, and one end of the first spring is fixedly connected to a rotating disk, and the rotating disk is coaxially rotatably connected to the clamping sleeve 150. The other end of the first spring is fixedly connected to the support block 140. The first spring is always in a stretched state, that is, the first spring has a force to drive the support block 140 and the clamping sleeve 150 to approach each other, ensuring that when the clamping sleeve 150 and the support block 140 jointly clamp the anti-corrosion pipe 130, the anti-corrosion pipe 130 can be in a stable state with the support block 140. In the initial state, the stopper can be provided to prevent the support block 140 from abutting against the clamping sleeve 150 , thereby ensuring that the anti-corrosion pipe 130 can be sleeved on the outside of the support block 140 .

[0043] In one embodiment, when the support block 140 is pulled to the outside of the metal tube 120, the anti-corrosion tube 130 reaches the installation standard, and the clamping sleeve 150 is driven to slide along the traction rod 170, and the clamping sleeve 150 is moved to one side of the block, so that the clamping sleeve 150 cannot be driven by the reset force of the first spring. At this time, the anti-corrosion tube 130 is heated again, and after the anti-corrosion tube 130 softens, the reset force of the second spring can drive the transmission rod 220 and the tightening rod 210 to rotate further, and the tightening rod 210 squeezes the anti-corrosion tube 130, so that the anti-corrosion tube 130 is turned outward, which is convenient for subsequent processing of the anti-corrosion tube 130 and the metal tube 120.

[0044] In one embodiment, the support block 140 is configured to be truncated cone-shaped. In the direction in which the anti-corrosion tube 130 is inserted into the metal tube 120, the end of the support block 140 with a smaller diameter is located at the front side of the moving direction of the anti-corrosion tube 130 inserted into the metal tube 120, and the end of the support block 140 with a larger diameter is located at the rear side of the moving direction of the anti-corrosion tube 130 inserted into the metal tube 120. The outer contour of the clamping sleeve 150 is similar to that of the support block 140, and the outer contour of the clamping sleeve 150 is larger than that of the support block 140. By setting the outer shapes of the clamping sleeve 150 and the support block 140, the anti-corrosion tube 130 is further prevented from being separated from the support block 140 during the process of being inserted into the metal tube 120.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
