Description

Technical Field

[0001] This utility model relates to the field of pipeline rust removal technology, and in particular to a pipeline anti-corrosion and rust removal device. Background Technology

[0002] Steel pipes are essential components for transporting fluids, powdery solids, and exchanging heat, playing a vital role in water conservancy projects and the transportation of oil and natural gas. During storage, steel pipes are prone to rust formation on their surface, necessitating the application of an anti-rust coating. To improve the adhesion between the coating and the steel pipe, debris must be removed from the pipe's surface.

[0003] Chinese patent document CN218082045U discloses a metal pipe anti-corrosion and rust removal device. It features a drive assembly mounted on the left end seat, with a conical head connected to the output end of the drive assembly, and an upper screw threaded onto the right end seat. This invention has a simple structure. A metal pipe is suspended between two conical heads, with the central axis of the conical heads aligned with the central axis of the metal pipe. The upper screw is then rotated, causing one conical head to move closer to the other, clamping the pipe. The spring's return force causes a sliding rod and its attached metal brush to move upwards, with the brush adhering tightly to the pipe. A drive motor, via the conical heads, drives the pipe to rotate, causing the pipe and brush to rotate relative to each other, thus grinding and removing rust circumferentially. A servo motor, via a lower screw, drives the sliding block and brush to move axially along the pipe, achieving rapid rust removal.

[0004] The existing technology has the following problems:

[0005] The aforementioned device, which uses two conical heads to fix the pipe, has a limited range of applications and is not practical. Secondly, in this device, as the metal bristles move axially along the pipe, the grinding debris falls entirely onto the surface of the lower lead screw, easily reducing its lifespan. Furthermore, the brush holder is connected to the slide rod via a spring. The spring's extension and retraction length is limited, making it unsuitable for pipes of different sizes.

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figures 1-6 As shown, a pipe anti-corrosion and rust removal device includes a base 1, with pipe fixing components 2 fixedly installed on the left and right sides of the upper end of the base 1, and a rust removal and cleaning component 3 movably connected to the middle of the upper end of the base 1.

[0029] The pipe fixing assembly 2 includes a fixed frame 21 and a movable frame 22. The lower end of the fixed frame 21 is fixedly installed to the upper left part of the base 1. The lower front and rear parts of the movable frame 22 are slidably connected to the upper right part of the base 1. Fixed cylinders 23 are rotatably connected to the inner walls of the tops of the fixed frame 21 and the movable frame 22 on opposite sides. A rotating mechanism is fixedly connected to the left side of the outer wall of the left fixed cylinder 23. Movable circular plates 24 are slidably connected to the inner walls of the two fixed cylinders 23. Adjusting components are movably connected to the opposite sides of the two movable circular plates 24. Symmetrically arranged conical heads 25 are fixedly installed on opposite sides of the movable circular plate 24. Four annularly distributed movable slots are opened on the side of the outer wall of the two fixed cylinders 23 that are close to each other. Rectangular rods 26 are slidably connected to the inner walls of the eight movable slots. An arc-shaped opening plate 27 is fixedly installed at one end of each of the four rectangular rods 26 near the axis of the corresponding fixed cylinder 23. The inner wall of each of the four opening plates 27 abuts against the outer wall of the corresponding conical head 25. A rubber support plate 28 is fixedly installed at one end of each of the four rectangular rods 26 away from the axis of the fixed cylinder 23.

[0030] The rust removal and cleaning component 3 includes two mounting plates 31. A lead screw 32 is rotatably connected to the inner wall of the two mounting plates 31. A motor 34 is fixedly installed on the right side of the right mounting plate 31. The output end of the motor 34 is fixedly connected to the right end of the lead screw 32. A sliding plate 33 is threadedly connected to the outer wall of the lead screw 32. A telescopic mechanism is fixedly installed at the upper end of the sliding plate 33. A metal brush plate 35 is detachably connected to the top of the telescopic mechanism. Corrugated sleeves 36 are fixedly installed in the middle of the left and right sides of the sliding plate 33. The side of the two corrugated sleeves 36 that is far away from each other is fixedly connected to the opposite side of the two mounting plates 31. The two corrugated sleeves 36 are located on the outside of the lead screw 32.

[0031] Pipe fixing assembly 2 can fix pipes of different lengths and diameters, offering a wide range of fixing options and simple operation. In application, simply rotate the two adjusting screws 29; when the two moving circular plates 24 drive the conical heads 25 closer together, they compress the corresponding opening plates 27, causing the rubber support plates 28 in groups of four to spread outwards, thus fixing the inner wall of the pipe, making it highly practical. Rust removal and cleaning assembly 3 can grind and remove rust from pipes rotated by a rotating mechanism; the left-right moving brush plate 35 is suitable for pipes of different lengths. The two corrugated sleeves 36 can extend and retract back and forth when the sliding plate 33 moves, protecting the lead screw 32. The telescopic mechanism can move the brush plate 35 up and down, offering a wide adjustment range and high practicality. Furthermore, the movement of the sliding plate 33 allows the cleaning plate 311 to sweep fallen debris into the two discharge troughs 312, effectively cleaning hard-to-reach areas in the middle of the base 1, reducing the workload of workers and enhancing its practicality.

[0032] The rotating mechanism is a common type of mechanism, typically consisting of two gears and a drive motor. The left outer wall of the left fixed cylinder 23 is fixedly connected to the inner wall of one gear. The drive motor is fixedly mounted on the left side of the fixed frame 21, and its output end is fixedly connected to the inner wall of the other gear. The two gears are meshed. When the drive motor starts, the left fixed cylinder 23 rotates, and the two fixed cylinders 23 rotate synchronously due to the connection of the fixed pipes.

[0033] like Figure 4 As shown, the two adjusting components are adjusting screws 29. The outer walls of the two adjusting screws 29 are threadedly connected to the inner walls of the two fixed cylinders 23 on the opposite side of each other. The opposite ends of the two adjusting screws 29 are rotatably connected to the middle of the two movable circular plates 24 on the opposite side of each other.

[0034] The inner walls of the two fixed cylinders 23 are provided with sliding grooves at the front and rear. The outer walls of the two movable circular plates 24 are slidably connected to the inner walls of the four sliding grooves. By rotating the two adjusting screws 29, the two adjusting screws 29 can drive the two movable circular plates 24 to move closer to each other or further away.

[0035] like Figure 4As shown, elastic elements 210 are movably sleeved on the outer sides of the eight rectangular rods 26 near the axis of the two fixed cylinders 23. Each elastic element 210 is located between the corresponding rubber support plate 28 and the inner wall of the corresponding fixed cylinder 23.

[0036] The elastic element 210 is a spring that provides a restoring force. When the two conical heads 25 move away from each other, the four rubber support plates 28 will return to their original shape due to the restoring force of the elastic element 210, which facilitates unloading from the pipeline and subsequent loading into the pipeline.

[0037] like Figure 3 As shown, an adjusting screw 211 is threadedly connected to the front part of the upper right side of the base 1, and the left end of the adjusting screw 211 is rotatably connected to the bottom front side of the movable frame 22.

[0038] Limiting grooves are provided at the front and rear positions of the upper right side of the base 1, and the front and rear parts of the lower end of the movable frame 22 are slidably connected to the inner walls of the two limiting grooves. Rotating the adjusting screw 211 can drive the movable frame 22 to move left and right, so that the four rubber support plates 28 on the right side can adapt to pipes of different lengths.

[0039] like Figure 5 and Figure 6 As shown, the telescopic mechanism includes a receiving frame 37 with an open top and a moving frame 38 with an open bottom. The lower end of the receiving frame 37 is fixedly installed at the middle of the upper end of the sliding plate 33. The outer side of the moving frame 38 is slidably connected to the inner side of the receiving frame 37. The lower end of the brush plate 35 is fixedly connected to the upper end of the moving frame 38. A cylinder 39 is fixedly installed at the middle of the bottom of the inner wall of the receiving frame 37. The output end of the cylinder 39 is fixedly connected to the top of the inner wall of the moving frame 38.

[0040] The output end of the cylinder 39 can drive the moving frame 38 to move up and down within the receiving frame 37, thereby allowing the brush plate 35 to adjust its height and thus adapt to pipes of different sizes.

[0041] like Figure 5 As shown, guide rods 310 are fixedly installed on the front and rear of the upper end of the base 1, and the inner walls of the front and rear of the slide plate 33 are slidably connected to the outer sides of the two guide rods 310.

[0042] The two guide rods 310 guide and limit the movement of the slide plate 33.

[0043] like Figure 6 As shown, a cleaning plate 311 is fixedly installed at the lower end of the slide plate 33, and a discharge chute 312 is provided on both the left and right sides of the upper end of the base 1. The inner walls of the two discharge chute 312 are inclined on the side that is close to each other.

[0044] When the slide plate 33 moves, the cleaning plate 311 can push the debris that is difficult to clean in the middle of the base 1 into the two discharge troughs 312.

[0045] The working principle of this utility model is as follows: When in use, the pipe is hoisted by a crane, and one end of the pipe is passed through the left fixed cylinder 23. The left adjusting screw 29 is rotated. The adjusting screw 29 is threadedly connected to the left fixed cylinder 23, which drives the moving circular plate 24 to move to the right. The conical head 25 moves to the right and squeezes the four corresponding opening plates 27, thereby causing the rubber support plates 28 in groups of four to spread outward, thus fixing the left side of the inner wall of the pipe. Then, according to the length of the pipe, the adjusting screw 211 is rotated. The adjusting screw 211 drives the moving frame 22 to move left and right, so that the right fixed cylinder 23 can be inserted into the other end of the pipe. When rotating the adjusting screw 211, the position of the right fixed cylinder 23 can be observed to prevent the right fixed cylinder 23 from going too deep into the pipe. Rotate the right adjustment screw 29 in the opposite direction to the left adjustment screw 29, consistent with the above steps. Move the circular plate 24 and the conical head 25 to the left, and the four rubber support plates 28 also spread outward, fixing the right side of the inner wall of the pipe, thereby fixing the entire pipe above the brush plate 35.

[0046] When the cylinder 39 is activated, its output end can drive the moving frame 38 to move up and down within the receiving frame 37, thereby allowing the brush plate 35 to adjust its height and thus adapt to pipes of different sizes.

[0047] Next, the rotating mechanism and motor 34 are started. The rotating mechanism drives the left fixed cylinder 23 to rotate. The two fixed cylinders 23 will rotate synchronously due to the connection of the fixed pipe. The output end of the motor 34 drives the lead screw 32 to rotate. The slide plate 33 moves left and right through its threaded connection. The brush plate 35 contacts the outer wall of the pipe and polishes and removes the rust on the outer wall of the pipe during rotation. The two corrugated sleeves 36 can extend and retract back and forth when the slide plate 33 moves, which protects the lead screw 32. In addition, the movement of the slide plate 33 can also allow the cleaning plate 311 to sweep the fallen debris into the two discharge troughs 312, which can clean the hard-to-clean area in the middle of the base 1 and reduce the burden on the staff.

[0048] 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.
