Description

Technical Field

[0001] This utility model belongs to the field of industrial cleaning equipment technology, specifically relating to an automated device that can adapt to the cleaning of the outer wall of steel pipes with different outer diameters. It achieves efficient cleaning of the outer wall of steel pipes by symmetrically adjusting the rinsing mechanism and the rotary conveying mechanism in synergy. Background Technology

[0002] With the continuous advancement of industrialization, steel pipes, as an important engineering material, are widely used in industries such as chemical, construction, petroleum, and food. During production and transportation, the surface of steel pipes is often contaminated by impurities such as oil, oxides, and dust, requiring cleaning to ensure their quality and performance. However, traditional steel pipe external wall cleaning devices mostly adopt a fixed water spray structure. This structure can only clean steel pipes of specific specifications, lacking sufficient flexibility and unable to adapt to steel pipes of different diameters. In practical applications, to accommodate steel pipes of different diameters, it is necessary to frequently adjust or replace clamps or cleaning heads, which not only increases the complexity of operation but also leads to low equipment efficiency.

[0003] Furthermore, existing cleaning equipment typically relies on manual intervention to complete the rotating cleaning of steel pipes, a method prone to uneven cleaning. Manual operation is not only inefficient but also prone to missing areas, resulting in unsatisfactory cleaning results. In addition, due to manual intervention, water usage during the cleaning process is often difficult to control precisely, leading to significant water waste and increasing production costs and environmental pressure. Summary of the Invention

[0004] To overcome the shortcomings of existing traditional cleaning equipment, such as poor adaptability, low cleaning efficiency, and water waste, this utility model provides a continuous steel pipe outer wall cleaning device with rotary feeding and adjustable target distance. By adjusting the spacing of the water spray bars and driving the steel pipe to rotate and feed, it can adapt to different pipe diameters and realize automatic rotation cleaning of steel pipes. It can automatically adjust the cleaning parameters according to the diameter specifications of the steel pipe, avoiding frequent changes of clamps and manual intervention, significantly improving cleaning efficiency and uniformity, and effectively saving water resources, meeting the needs of modern industrial production for automation, environmental protection, and high efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A continuous steel pipe outer wall cleaning device with rotary feeding and adjustable target distance includes an outer wall cleaning module, a steel pipe conveying module, and a sludge collection frame module. The steel pipe conveying module is used to convey the steel pipe to be cleaned to the counter-flushing cleaning station of the outer wall cleaning module. The sludge collection frame module is used to receive the sludge cleaned from the outer wall of the steel pipe and is located below the water tank of the outer wall cleaning module. The outer wall cleaning module includes an outer wall cleaning tank, a symmetrical flushing guide rail, a symmetrical flushing rod module, and a symmetrical sliding module for moving the two spray rods of the symmetrical flushing rod module closer or further apart. The symmetrical flushing guide rail is installed at both ends of the outer wall cleaning tank along the direction of the steel pipe's movement. The symmetrical flushing guide rail is perpendicular to the symmetrical flushing rod module, and both ends of the symmetrical flushing rod module are slidably mounted on the symmetrical flushing guide rail. The symmetrical flushing rod module is connected to the actuating end of the symmetrical sliding module, and the two spray rods of the symmetrical flushing rod module are symmetrically arranged on both sides of the steel pipe to be cleaned.

[0006] Furthermore, the symmetrical sliding module includes a sliding drive motor and a double helix screw mechanism. The output shaft of the sliding drive motor is connected to the double helix screw mechanism, which is located on the center line of the symmetrical flushing guide rail. The two screws of the double helix screw mechanism are respectively linked to one spray bar of the symmetrical flushing rod module.

[0007] The symmetrical sliding module also includes a control system. This control system comprises a displacement sensor for monitoring the spacing of the spray booms, a laser sensor for detecting the outer diameter of the steel pipe to be cleaned, and a target distance adjustment module for determining the spacing of the spray booms based on the outer diameter of the steel pipe and controlling the movement of the sliding drive motor. The target distance adjustment module is connected to the controlled end of the sliding drive motor. This scheme forms a closed-loop feedback control, achieving automated adjustment of the target distance.

[0008] The double-helix screw mechanism includes a double-helix screw and a screw nut sleeved on it. The screw nut is fixedly connected to a nut mounting plate, and the output shaft of the sliding drive motor is connected to the double-helix screw. In this design, the double-helix screw mechanism controls two water spray bars to slide simultaneously, with the two water spray bars moving closer or further apart to accommodate cleaning the outer walls of steel pipes with different outer diameters.

[0009] Preferably, the spray bar of the symmetrical flushing bar module is fixed to the nut mounting plate by U-bolts, and the spray bar is perpendicular to the double helical screw mechanism. In this design, the U-bolts pass through the mounting holes of the nut mounting plate and lock the spray bar in place, forming a detachable rigid connection structure.

[0010] Furthermore, the symmetrical flushing rod module includes a spray rod, a clamp, a pipe clamp, and a pipe clamp mounting plate. The pipe clamp mounting plate is mounted on the symmetrical flushing guide rail. Both ends of the flushing rod are fixed by the spray rod clamp, which is fixed in the pipe clamp. The pipe clamp is mounted on the pipe clamp mounting plate.

[0011] The pipe clamp and the pipe clamp mounting plate are connected by a snap-on quick-release structure. This design facilitates quick replacement or maintenance of the water spray bar.

[0012] The sludge collection frame module is equipped with a detachable filter screen, which is arranged at an angle to separate sludge from flushing water. The side wall of the sludge collection frame module is provided with a drain outlet for discharging the filtered flushing water.

[0013] Preferably, the outer wall cleaning tank includes a drain trough at its bottom, the drain trough being inclined and connected to the sludge collection frame module, for guiding the rinsed sludge into the sludge collection frame module for centralized collection.

[0014] The steel pipe conveying module includes V-wheel assemblies spaced at intervals. Each V-wheel assembly includes a V-wheel and a conveying drive motor that drives its rotation. The axis of the V-wheel is at a preset angle to the conveying direction of the steel pipe. This design allows the steel pipe to rotate and move forward simultaneously under the frictional force of the V-wheel during feeding, achieving rotational cleaning of the outer wall of the steel pipe.

[0015] The beneficial effects of this utility model are mainly reflected in: 1. The automatic adjustment of the spray bar spacing is achieved through the linkage between the double helix screw mechanism and the nut mounting plate, adapting to different pipe diameters; 2. The V-wheel assembly drives the steel pipe to rotate and feed it in, ensuring uniform cleaning of the entire circumference of the outer wall; 3. Modular design facilitates maintenance and improves cleaning efficiency by more than 30%. Attached Figure Description

[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] Reference Figure 1A continuous steel pipe outer wall cleaning device with rotary feeding and adjustable target distance includes an outer wall cleaning module 1, a steel pipe conveying module 3, and a sludge collection frame module 2. The steel pipe conveying module 3 is used to convey the steel pipe to be cleaned to the counter-flushing cleaning station of the outer wall cleaning module 1. The sludge collection frame module 2 is used to receive the sludge cleaned from the outer wall of the steel pipe, and the sludge collection frame module 2 is located below the water tank of the outer wall cleaning module 1. The outer wall cleaning module 1 includes an outer wall cleaning box 4, a symmetrical flushing guide rail 1-2, a symmetrical flushing rod module 6, and a symmetrical sliding module 5 for moving the two spray rods of the symmetrical flushing rod module closer or further apart. The symmetrical flushing guide rail 1-2 is installed at both ends of the outer wall cleaning box along the direction of the steel pipe's movement. The symmetrical flushing guide rail 1-2 is perpendicular to the symmetrical flushing rod module 6. The two ends of the symmetrical flushing rod module 6 are slidably installed on the symmetrical flushing guide rail 1-1. The symmetrical flushing rod module 6 is connected to the actuating end of the symmetrical sliding module 5. The two spray rods of the symmetrical flushing rod module 6 are symmetrically arranged on both sides of the steel pipe to be cleaned.

[0024] In this embodiment, the steel pipe conveying module 3 is used to convey the steel pipe to be cleaned to the cleaning station in the outer wall cleaning box 4 of the outer wall cleaning module 1. The sludge from the steel pipe cleaning falls into the sludge collection frame module 2 below through the drain trough at the bottom of the symmetrical outer wall cleaning module 1.

[0025] like Figure 3 As shown, the outer wall cleaning module 1 also includes a symmetrical flushing guide rail base 1-3, which is fixed on the cleaning box frame 4-3 of the outer wall cleaning box 4.

[0026] The symmetrical sliding module 5 includes a sliding drive motor 5-1 and a double helical screw mechanism 7. Activating the sliding drive motor 5-1 drives the double helical screw 7-1, causing the screw nut 7-2 to move towards the center or both sides, thus increasing or decreasing the spacing of the water spray rods 6-1 on the nut mounting plate 7-3. Before the steel pipe enters the cleaning station, a laser sensor detects the outer diameter of the steel pipe in real time, feeding back to the control system to fine-tune the spacing of the water spray rods 6-1 to a specific distance from the steel pipe diameter. After adjustment, the nut mounting plate 7-3 is fixed to the cleaning box frame 4-3 by an electromagnetic lock, ensuring stability during the rinsing process.

[0027] like Figure 4As shown, the symmetrical rinsing rod module 6 includes a spray rod 6-1, clamps 6-2, pipe clamps 6-3, and a pipe clamp mounting plate 6-4. The spray rod 6-1 has clamps 6-2 at both ends, which are held and fixed by the pipe clamps 6-3. The pipe clamps 6-3 are mounted on the pipe clamp mounting plate 6-4, thus fixing both ends of the spray rod 6-1 to the slider of the guide rail 1-2. The spray rod 6-1 is fixed to the nut mounting plate by U-bolts 7-4, and the ball screw mechanism 7 controls the back-and-forth sliding of the spray rod 6-1 on the guide rail, thereby accommodating the cleaning of steel pipes with different outer diameters.

[0028] like Figure 6 The steel pipe conveying module shown has a V-wheel assembly 8, whose V-wheel 8-1 has a 40° inclination angle, creating a frictional force component with the steel pipe feeding direction to ensure uniform rotation of the steel pipe. The specific workflow is as follows: The steel pipe is placed on the V-wheel 8-1 via the loading rack device. The conveying drive motor 8-2 moves, and all V-wheel assemblies 8 rotate in the same direction. The steel pipe, under the action of friction, begins to rotate and is fed forward. When the steel pipe enters the symmetrical cleaning box module 4, the high-pressure water flow from the spray bar 6-1 covers the outer wall of the steel pipe at a 60° fan angle. The V-wheel assembly 8 continuously drives the steel pipe to rotate, ensuring no cleaning blind spots. The cleaned steel pipe is conveyed by the V-wheel assembly 8 to the downstream station. The sludge is filtered through the drain trough 4-2 at the bottom of the symmetrical cleaning box module 4 and then flows along the guide channel into the sludge collection box 2-1 of the sludge collection frame module 2.

[0029] like Figure 3 and Figure 4 The symmetrical flushing module shown features an O-ring seal between the clamp 6-2 and the spray bar 6-1 to prevent high-pressure water leakage. The nozzle of the spray bar 6-1 is detachable and secured by a threaded connection, facilitating regular cleaning of scale or replacement. Furthermore, an inspection door is located on the side wall of the cleaning box frame 4-3, allowing for quick disassembly of the symmetrical sliding module 5 for maintenance.

[0030] For mass production scenarios, the device supports continuous cleaning of steel pipes of various specifications: parameters can be preset, and different steel pipe diameters (such as Φ219mm, Φ273mm, Φ426mm, etc.) can be input into the control system. The corresponding spray bar spacing (6-1), water flow pressure, and inclined wheel speed are automatically matched by the control system. After the current steel pipe is cleaned, the system automatically adjusts the spray bar spacing according to the parameters of the next steel pipe.

[0031] The cleaning method of this continuous cleaning device for the outer wall of steel pipe includes the following steps: Step 1: The steel pipe is placed on the V-wheel 8-1 of the V-wheel assembly 8 in the steel pipe conveying module by the feeding rack device. The conveying drive motor 8-2 drives each V-wheel assembly 8 to continuously rotate and feed the steel pipe into the outer wall cleaning box 4 from one side and reach the outer wall cleaning station.

[0032] Step 2: Upon first use, the spray bar 6-1 needs to be slid to a suitable position so that the two spray bars 6-1 flush the steel pipe of the specified outer diameter. The sliding drive motor controls the nut mounting plate 7-3 to slide along the double helical screw 7-1, allowing the steel pipe to reach the symmetrical flushing outer wall cleaning tank 4. This causes the spray bars 6-1 to slide relative to each other on the symmetrical flushing guide rail 1-2 until the nozzles move to a fixed distance to clean the steel pipe and stop.

[0033] Step 3: The steel pipe is rotated and fed in under the drive of V-wheel assembly 8 so that the fan-shaped water surface sprayed by each nozzle can cover the entire area of ​​the steel pipe.

[0034] Step 4: The V-wheel assembly 8 drives the steel pipe forward, leaving the outer wall cleaning station from the other side of the outer wall cleaning box 4 and entering the discharge V-wheel assembly.

[0035] Step 5: Repeat steps 1 to 4 to complete the cleaning of the outer walls of multiple steel pipes.

[0036] The embodiments described in this specification are merely examples of implementations of the inventive concept and are for illustrative purposes only. The scope of protection of this utility model should not be considered limited to the specific forms described in these embodiments; rather, it extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
