Description

Technical Field

[0001] This utility model relates to the field of rust removal technology for gas pipelines, and in particular to a rust removal device for gas pipelines. Background Technology

[0002] Corrosion protection of gas pipelines is a key process to ensure and extend their service life. In order to ensure that the anti-corrosion layer is firmly bonded to the pipe wall, rust removal is the most critical step. Generally, the pipes have varying degrees of rust on their inner walls due to factors such as the manufacturing time, storage and transportation conditions, and the humidity level of the climate.

[0003] Currently, the main methods for rust removal of gas pipelines on the market are manual rust removal. Manual rust removal usually relies on operators using simple rust removal tools, such as wire brushes and sandpaper, to directly grind and remove rust from the inner wall of the gas pipeline, which is inefficient and difficult to meet the needs of large-scale gas pipeline rust removal operations. Therefore, we have launched a new gas pipeline rust removal device. Utility Model Content

[0004] The main objective of this invention is to provide a rust removal device for gas pipelines, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rust removal device for gas pipelines includes a base, a connecting seat fixedly connected to the upper end of the base, an installation cavity opened in the middle of the right end of the connecting seat, a rust removal mechanism fixedly installed inside the installation cavity, a fixing mechanism fixedly connected to the upper end of the connecting seat, a gas pipeline body disposed inside the fixing mechanism, and a sliding seat fixedly connected to the middle of the right end of the base, with sliding grooves opened at both the front and rear ends of the sliding seat.

[0007] Preferably, the rust removal mechanism includes a hydraulic telescopic rod, the output end of which is fixedly mounted with a displacement seat, an extension plate is fixedly connected to the front and rear lower ends of the displacement seat, a slide bar is fixedly connected to the opposite surfaces of the two extension plates, a mounting base is fixedly connected to the middle upper end of the displacement seat, a motor is fixedly mounted to the right end of the mounting base, the output end of the motor is fixedly connected to a rotating column via a rotating rod, and a friction ring is detachably connected to the left end of the rotating column.

[0008] Preferably, the hydraulic telescopic rod is fixedly installed inside the mounting cavity, and the lower end of the displacement seat does not contact the upper end of the slide.

[0009] By adopting the above technical solution, the displacement seat can be moved to the left by the retraction force of the hydraulic telescopic rod, which allows the friction ring to automatically enter the interior of the gas pipeline body.

[0010] Preferably, neither of the two extension plates contacts the side of the slide block, and the two slide bars are slidably connected to the two slide grooves respectively.

[0011] By adopting the above technical solution, the movement of the displacement seat can be made more stable.

[0012] Preferably, the friction ring corresponds to the horizontal position of the gas pipeline body, and the diameter of the friction ring is consistent with the inner diameter of the gas pipeline body.

[0013] By adopting the above technical solution, the friction ring can perform mechanized rust removal on the inner wall of the gas pipeline body from right to left.

[0014] Preferably, the fixing mechanism includes a fixing seat, the upper end of which has a groove, and cylinders are fixedly installed on the left and right front ends, as well as the left and right rear ends of the fixing seat. Extrusion plates are fixedly installed on the output ends of the four cylinders, and extrusion pads are fixedly connected to the inner surfaces of the four extrusion plates.

[0015] Preferably, the lower end of the fixed seat is fixedly connected to the connecting seat, all four extrusion plates are located inside the fixed seat, and the inner surfaces of the four extrusion pads are tightly fitted to the gas pipeline body.

[0016] By adopting the above technical solution, four cylinders drive four extrusion plates to extrude the outer side of the gas pipeline body, so that the gas pipeline body can be fixed in the fixed seat, avoiding the gas pipeline from shaking, shifting or even falling off due to the external force generated by the rotation of the friction ring during the rust removal operation, and ensuring that the rust removal operation can be carried out stably.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By activating the hydraulic telescopic rod, the retraction force of the hydraulic telescopic rod drives the displacement seat to move to the left, allowing the friction ring to automatically enter the interior of the gas pipeline body. At the same time, the motor drives the friction ring to rotate through the rotating rod and rotating column, enabling the friction ring to perform mechanized rust removal on the inner wall of the gas pipeline body from right to left. Since the friction ring is detachable, when it is necessary to remove rust from gas pipeline bodies with different inner diameters, friction rings of different diameters can be replaced. Compared with the existing manual operation or manual rust removal machine methods, the rust removal process is more efficient and the rust removal efficiency is improved, making it more suitable for large-scale gas pipeline rust removal work.

[0019] 2. By placing the gas pipeline body in the fixed seat and using four cylinders to drive four extrusion plates to press the outside of the gas pipeline body, the gas pipeline body can be fixed in the fixed seat. This prevents the gas pipeline from shaking, shifting, or even falling off due to the external force generated by the rotation of the friction ring during the rust removal operation, ensuring that the rust removal operation can be carried out stably.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A gas pipeline rust removal device includes a base 1, a connecting seat 2 fixedly connected to the upper end of the base 1, an installation cavity 3 opened in the middle of the right end of the connecting seat 2, a rust removal mechanism 4 fixedly installed inside the installation cavity 3, a fixing mechanism 5 fixedly connected to the upper end of the connecting seat 2, a gas pipeline body 6 arranged inside the fixing mechanism 5, and a sliding seat 7 fixedly connected to the middle of the right end of the base 1, with sliding grooves 8 opened at both the front and rear ends of the sliding seat 7.

[0030] In this embodiment, the rust removal mechanism 4 includes a hydraulic telescopic rod 41. A displacement seat 42 is fixedly installed at the output end of the hydraulic telescopic rod 41. An extension plate 43 is fixedly connected to the front and rear of the lower end of the displacement seat 42. Slide strips 44 are fixedly connected to the opposite surfaces of the two extension plates 43. A mounting seat 45 is fixedly connected to the middle of the upper end of the displacement seat 42. A motor 46 is fixedly installed at the right end of the mounting seat 45. A rotating column 47 is fixedly connected to the output end of the motor 46 through a rotating rod. A friction ring 48 is detachably connected to the left end of the rotating column 47. The hydraulic telescopic rod 41 is fixedly installed inside the mounting cavity 3. The lower end of the displacement seat 42 does not contact the upper end of the slide 7. The two extension plates 43 do not contact the sides of the slide 7. The two slide strips 44 are slidably connected to the two sliding grooves 8 respectively. The friction ring 48 corresponds to the horizontal position of the gas pipeline body 6, and the diameter of the friction ring 48 is consistent with the inner diameter of the gas pipeline body 6.

[0031] The above solution involves activating the hydraulic telescopic rod 41, which, through its retraction force, moves the displacement seat 42 to the left, allowing the friction ring 48 to automatically enter the gas pipeline body 6. Simultaneously, the motor 46, via the rotating rod and rotating column 47, drives the friction ring 48 to rotate, enabling the friction ring 48 to perform mechanized rust removal on the inner wall of the gas pipeline body 6 from right to left. Furthermore, since the friction ring 48 is detachable, different diameter friction rings 48 can be replaced when rust removal is required for gas pipeline bodies 6 with different inner diameters. Compared to the existing methods that mostly rely on manual operation or manual rust removal machines, this method makes the rust removal process more efficient and improves rust removal efficiency, making it more suitable for large-scale rust removal work on gas pipelines.

[0032] In this embodiment, the fixing mechanism 5 includes a fixing seat 51. The upper end of the fixing seat 51 has a groove 52. Cylinders 53 are fixedly installed on the left and right front ends, as well as the left and right rear ends of the fixing seat 51. Extrusion plates 54 are fixedly installed on the output ends of the four cylinders 53. Extrusion pads 55 are fixedly connected to the inner surfaces of the four extrusion plates 54. The lower end of the fixing seat 51 is fixedly connected to the connecting seat 2. The four extrusion plates 54 are all located inside the fixing seat 51. The inner surfaces of the four extrusion pads 55 are all tightly fitted to the gas pipeline body 6.

[0033] The above solution involves placing the gas pipeline body 6 inside the fixed seat 51 and using four cylinders 53 to drive four pressing plates 54 to press the outside of the gas pipeline body 6, thus fixing the gas pipeline body 6 inside the fixed seat 51. This prevents the gas pipeline body 6 from shaking, shifting, or even falling off during the rust removal process due to the external force generated by the rotation of the friction ring 48, ensuring that the rust removal operation can be carried out stably.

[0034] It should be noted that this utility model is a rust removal device for gas pipelines. During use, the gas pipeline body 6 is placed in the fixed base 51. Four cylinders 53 drive four extrusion plates 54 respectively, causing the extrusion plates 54 to extrude from the outside of the gas pipeline body 6, thereby fixing the gas pipeline body 6 in the fixed base 51. This ensures that subsequent rust removal work can be carried out stably. When performing rust removal work on the gas pipeline body 6, the hydraulic telescopic rod 41 is activated. Its retraction force drives the displacement seat 42 to move to the left, thereby causing the friction ring 48 to automatically enter the gas pipeline body 6. Inside, the motor 46 drives the rotating column 47 to rotate via the rotating rod, and the rotating column 47 then drives the friction ring 48 to rotate. This enables the friction ring 48 to mechanically remove rust from the inner wall of the gas pipeline body 6 from right to left. Moreover, since the friction ring 48 is detachable, when facing gas pipeline bodies 6 with different inner diameters that need rust removal, it is only necessary to replace the friction ring 48 with the corresponding diameter. Compared with the existing methods of rust removal that mostly use manual operation or manual rust removal machines, the rust removal process is more efficient, improves rust removal efficiency, and better meets the rust removal needs of large-scale gas pipelines.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
