Description

Technical Field

[0001] The invention relates to the technical field of pipeline anti-corrosion spraying, and in particular to a pipeline inner wall spraying machine capable of evenly spraying. Background Art

[0002] In many industrial fields, such as oil, natural gas, chemical industry, water supply and drainage, pipelines are widely used to transport various fluid media. Since pipelines are in harsh working environments for a long time, such as being exposed to humid, corrosive gas or liquid environments, the inner wall of the pipeline is susceptible to corrosion, which not only affects the service life of the pipeline, but may also cause medium leakage, leading to serious problems such as safety accidents and environmental pollution. In order to extend the service life of the pipeline and ensure its safe operation, anti-corrosion painting of the inner wall of the pipeline is a common and effective protective measure. By forming a uniform and dense anti-corrosion coating on the inner wall of the pipeline, the inner wall of the pipeline can be effectively isolated from the contact with the corrosive medium, thereby slowing down the corrosion rate.

[0003] Disadvantages of existing pipeline inner wall spraying machines

[0004] (1) Adaptation to pipeline size

[0005] Poor versatility

[0006] Many existing pipe inner wall spraying machines lack flexibility in design and are often only suitable for pipes within a specific diameter range. When faced with pipes of different shapes (such as round, oval, etc.) and diameters, it is necessary to replace different models of spraying machines or make complex adjustments to the equipment, which increases costs and operational complexity, limiting its application in a variety of pipeline projects.

[0007] (II) Spraying uniformity

[0008] Uneven spraying

[0009] Some existing sprayers have defects in the distribution and spraying methods of the spray liquid. Some equipment does not have an effective diversion device, resulting in uneven flow of the spray liquid in different directions, which in turn causes the inner wall of the pipe to be sprayed too thick or too thin in some areas. In addition, the structure of the spray nozzle and the spray power control are not precise enough to ensure that the spray liquid is sprayed in a uniform spray form, making it difficult to achieve comprehensive and uniform coverage of the inner wall of the pipe.

[0010] Lack of visual adjustments

[0011] Most traditional pipe inner wall spraying machines lack visual monitoring and real-time adjustment functions for the spraying process. Operators cannot timely and accurately understand the spraying conditions of the inner wall of the pipe, find areas with uneven spraying or defects, and cannot adjust the spraying parameters in time, which makes it difficult to effectively guarantee the final spraying quality.

[0012] (III) Overall control

[0013] Low level of intelligence

[0014] Traditional pipe inner wall spraying machines usually lack a complete intelligent control system. The coordination between various functional components is poor. For example, the travel control and spraying control are often carried out independently, and there is no central control module to coordinate the work between them. This results in the inability to make real-time and accurate adjustments according to the actual situation of the inner wall of the pipe and the spraying progress during the spraying process, affecting the efficiency and quality of the spraying.

[0015] Difficulty in tracking quality

[0016] Existing spraying machines rarely have data recording and quality tracking functions. After spraying is completed, it is impossible to obtain detailed data on the spraying process, such as the change of spraying pressure and spraying volume over time, and there is no spraying image record at different positions on the inner wall of the pipe. This makes it difficult for technicians to fully evaluate the spraying quality, which is not conducive to discovering potential problems and improving the spraying process.

[0017] Therefore, this invention proposes a pipeline inner wall spraying machine which can spray uniformly to solve the above problems. Summary of the invention

[0018] In order to overcome the defects of the prior art, the object of the present invention is to provide a pipe inner wall spraying machine which can spray uniformly.

[0019] To achieve the above object, the technical solution of the present invention is implemented as follows: a pipe inner wall spraying machine capable of uniform spraying includes a walking assembly, wherein the walking assembly has two walking assemblies arranged in a front-to-rear order, the front and rear walking assemblies are connected by a connecting soft rod, and a liquid inlet spraying assembly is connected to the rear of the rear walking assembly;

[0020] The liquid inlet spraying assembly specifically includes the following structures:

[0021] Connected to the reduction motor at the tail end of the rear traveling assembly;

[0022] Connected to the five-way pipe on the output end of the reduction motor;

[0023] Liquid guide tubes connected to the four outlet ends of the four-way tube;

[0024] A spray nozzle connected to the liquid outlet end of each liquid guide tube;

[0025] A butt-jointed pipe connected to the rear end of the bottom bracket tube;

[0026] A liquid inlet hose that is rotatably connected to the inside of the butt pipe and is connected to the inside of the five-way pipe;

[0027] The camera is installed on the four sides of the liquid inlet hose.

[0028] Preferably, the walking assembly specifically includes the following structure:

[0029] A first mounting seat connected to the end of the flexible rod;

[0030] A stepping cylinder docked on the end surface of the first mounting seat;

[0031] A second mounting seat connected to the output end of the stepping cylinder;

[0032] The tightening walking parts are correspondingly installed in three directions between the first mounting seat and the second mounting seat.

[0033] Preferably, the tightening walking component specifically includes the following structure:

[0034] Connecting rods respectively hinged to the outer side walls of the first mounting seat and the second mounting seat;

[0035] The other ends of the connecting rods on both sides are hinged together with a mounting plate;

[0036] A mounting bracket mounted on the outer end surface of the mounting plate;

[0037] Travel wheels mounted on the mounting frame;

[0038] The drive motor is installed on the outside of the mounting frame, and the output end of the drive motor is connected to the walking wheel.

[0039] Preferably, the two connecting rods are distributed in a herringbone shape.

[0040] Preferably, it also includes:

[0041] Central control module, data processing module, travel control module, spray control module and data storage module.

[0042] Preferably, the central control module is responsible for overall control and coordination of the work of each submodule;

[0043] Data processing module: used to receive the internal visual data of the liquid spraying component.

[0044] Preferably, the walking control module is used to control the movement of the walking component, including forward, backward, stop and other functions.

[0045] Preferably, the spray control module is used to control the spraying process of the liquid-inlet spraying component, including spraying time, spraying pressure, spraying amount, etc.

[0046] Preferably, the data storage module is used to record data and images during the spraying process for subsequent analysis and quality tracking.

[0047] The beneficial effects of the present invention are embodied in:

[0048] 1. Beneficial effects related to walking components

[0049] Adapts to various pipe sizes

[0050] In the walking assembly, the tightening walking parts are installed correspondingly in three directions between the first mounting seat and the second mounting seat, and the distance between the first mounting seat and the second mounting seat is accurately controlled by the stepping cylinder. It can adapt to pipes of different shapes and diameters, so that the sprayer can move stably in various pipes, thereby improving the versatility of the equipment.

[0051] High walking stability

[0052] The connecting rods of the tightening travel parts are distributed in a herringbone shape. This structure makes the tightening travel parts more stable when tightening the inner wall of the pipeline and evenly shares the pressure from the travel wheels. At the same time, the outer surface of the travel wheels is made of wear-resistant materials and the diameter and width are optimized according to the common pipeline sizes, which have good grip. In addition, the drive motor can provide power to meet the walking needs of pipelines with different diameters and roughness. These factors together ensure that the travel components can walk stably in the pipeline.

[0053] There are two walking assemblies which are arranged in a front-to-back order and connected by a connecting soft rod in the middle. This structure enables the two front and rear walking assemblies to work together and maintain a relatively stable spacing, further improving the walking stability of the entire sprayer.

[0054] 2. Beneficial effects of liquid spraying components

[0055] Good spraying uniformity

[0056] In the liquid inlet spraying assembly, the reduction motor can adjust the output speed according to actual needs, thereby controlling the uniformity of the rotary spraying. The five-way pipe acts as a diversion component to evenly distribute the spraying liquid to the four outlet ends, and then transmits it to the spraying nozzle through the liquid guide pipe. The spraying nozzle can spray the spraying liquid in a uniform spray form, and driven by the reduction motor, the entire spraying component rotates to cooperate with the sprayer to move forward, achieving a uniform spraying operation that fully covers the inner wall of the pipeline.

[0057] Spraying visualization and precise adjustment

[0058] Cameras are installed on the four sides of the liquid inlet hose. The cameras can clearly capture every corner of the inner wall of the pipe. The data processing module performs real-time analysis on the images taken by the cameras. The central control module adjusts the spraying parameters through the spraying control module based on the analysis results. If an uneven spraying area is found, the spraying parameters of the spray nozzle can be adjusted in time to ensure the spraying quality.

[0059] 3. Beneficial effects related to the whole system

[0060] Intelligent control

[0061] The central control module is responsible for overall control and coordination of the work of each submodule. It receives feedback from each module and makes decisions like a brain, accurately controlling other modules. The travel control module can accurately control the movement of the travel component according to the instructions of the central control module, and the spray control module can adjust the spray process of the liquid spray component according to various factors. This intelligent control system improves the accuracy and efficiency of spraying.

[0062] Quality tracking and process improvement

[0063] The data storage module can record data and images during the spraying process, such as the curve of spraying pressure change over time, images of different positions on the inner wall of the pipe, etc. After the spraying is completed, technicians can view these data and images to evaluate the spraying quality and make improvements based on possible problems, which is conducive to improving the spraying process level and also convenient for tracing the spraying quality.

[0064] This pipe inner wall spraying machine that can spray uniformly has many advantages. In terms of walking, its unique walking component design enables it to adapt to pipes of various shapes and diameters, and it has extremely high stability when walking in the pipe. Whether it is the structural optimization of the top-tight walking component or the connection method between the two walking components, it provides a strong guarantee for stable walking. In the spraying operation, the liquid inlet spraying component ensures the uniformity of the inner wall spraying of the pipe from the uniform distribution of the spraying liquid to the uniform spraying of the spraying nozzle, and then to the rotation cooperation of the entire spraying component. Moreover, the setting of the camera realizes the visualization of the spraying process and provides a basis for the precise adjustment of the spraying parameters. From the perspective of the overall system, the coordinated work of the central control module, data processing module, walking control module, spraying control module and data storage module enables the sprayer to achieve intelligent control. This intelligence is not only reflected in the real-time adjustment during the spraying process, but also in the effective tracking of the spraying quality and the continuous improvement of the spraying process. Through the rich data and images recorded by the data storage module, technicians can deeply analyze various situations in the spraying process, thereby continuously optimizing the spraying process, improving the spraying quality, and quickly locating the cause when quality problems occur. In summary, this sprayer has high value in the field of pipeline inner wall spraying, can meet the needs of different pipeline spraying, improve spraying efficiency and quality, and help promote the development and improvement of spraying technology.

[0077] Please refer to the instruction manual Figure 1-Figure 4 The present invention provides a pipe inner wall spraying machine capable of uniform spraying:

[0078] The sprayer includes a walking assembly 2 and a liquid inlet spraying assembly 1. There are two walking assemblies 2, which are arranged in a front-to-back order and are connected by a connecting soft rod 3. This connection method enables the front and rear two walking assemblies 2 to work together, maintain a relatively stable spacing, adapt to the operation requirements of pipelines of different lengths, and also improve the walking stability of the entire sprayer. The rear of the rear walking assembly 2 is docked with the liquid inlet spraying assembly 1, and the two are tightly docked to ensure that the liquid inlet spraying assembly 1 can stably perform the spraying operation during the walking process.

[0079] The specific structure of the liquid inlet spraying assembly 1 is as follows: a reduction motor 11 is connected to the tail end of the rear walking assembly 2. The main function of the reduction motor 11 is to provide suitable power transmission for subsequent spraying. It can adjust the output speed according to actual needs, thereby controlling the uniformity of the rotary spraying. A five-way pipe 12 is connected to the output end of the reduction motor 11. As a key diversion component, the five-way pipe 12 can evenly distribute the spray liquid input from the liquid inlet hose 17 to the four outlet ends. The four outlet ends of the four-way pipe 12, the top, bottom, left and right, are connected to the liquid guide pipe 13. The design of the liquid guide pipe 13 can effectively transmit the spray liquid diverted from the five-way pipe 12 to the spray nozzle 14. The liquid outlet end of each liquid guide tube 13 is connected with a spray nozzle 14. The structure of the spray nozzle 14 is specially designed to spray the spray liquid transmitted by the liquid guide tube 13 in a uniform spray form. At the same time, under the drive of the reduction motor 11, the five-way pipe 12 and the four liquid guide tubes 13 and the spray nozzle 14 rotate, and cooperate with the entire sprayer to move forward, thereby achieving a comprehensive coverage of the inner wall of the pipeline spraying operation. The rear end of the five-way pipe 12 is connected with a butt pipe 15, which serves to connect the liquid inlet hose 17 and the five-way pipe 12. Its internal structure can ensure that the liquid inlet hose 17 still maintains good connectivity during the rotation process. A liquid inlet hose 17 is rotatably connected to the inside of the butt joint 15. The liquid inlet hose 17 has good flexibility and can adapt to the bending environment in the pipeline while ensuring the stable transmission of the spray liquid from the external pump body. The liquid inlet hose 17 is connected to the inside of the five-way pipe 12. Cameras 16 are installed on the four sides of the liquid inlet hose 17. The camera 16 adopts a high-resolution, wide-angle lens and can clearly capture every corner of the inner wall of the pipeline, providing accurate visual data for subsequent spraying adjustments.

[0080] The specific structure of the walking component 2 is as follows: the end of the connecting soft rod 3 is docked with a first mounting seat 21, and the first mounting seat 21 provides a stable basic connection point for the entire walking component 2, which can withstand forces from all directions. The end face of the first mounting seat 21 is docked with a stepping cylinder 23, which is a key component for adjusting the degree of fit between the walking component 2 and the inner wall of the pipeline. It can accurately control the output stroke, thereby changing the distance between the first mounting seat 21 and the second mounting seat 22, and then adjusting the deployment and recovery operation of the top-tightening walking component 24. The output end of the stepping cylinder 23 is docked with a second mounting seat 22, and the second mounting seat 22 cooperates with the first mounting seat 21 to provide installation support for the top-tightening walking component 24. The top-tightening walking component 24 is correspondingly installed in three directions between the first mounting seat 21 and the second mounting seat 22. This three-directional layout can ensure that the walking component 2 can walk stably in the pipeline and adapt to pipelines of different shapes and diameters.

[0081] The specific structure of the tightening walking component 24 is as follows: the connecting rod 241 is hinged on the outer side wall of the first mounting seat 21 and the second mounting seat 22 respectively. The connecting rod 241 is a key component connecting the first mounting seat 21, the second mounting seat 22 and the mounting plate 242. It can flexibly adjust the angle under the action of the stepping cylinder 23, thereby changing the position of the mounting plate 242. The other end of the connecting rod 241 on both sides is hinged with a mounting plate 242. The mounting plate 242 provides a stable mounting plane for the mounting frame 243, which can withstand the reaction force generated by the walking wheel 245 during the walking process. The mounting frame 243 is installed on the outer end surface of the mounting plate 242. The structural design of the mounting frame 243 is reasonable, and it can firmly install the walking wheel 245 and the driving motor 244, and ensure the relative position between them is accurate. The mounting frame 243 is provided with a running wheel 245, the outer surface of which is made of wear-resistant material, has good grip, and can stably run on the inner wall of the pipeline, and the diameter and width of the running wheel 245 are optimized and designed according to the size of common pipelines to ensure the stability of running. The outer side of the mounting frame 243 is provided with a driving motor 244, which provides power for the running wheel 245, and its output power and torque can meet the requirements of running in pipelines with different diameters and roughnesses. The output end of the driving motor 244 is connected to the running wheel 245, and the two connecting rods 241 are distributed in a herringbone shape, which can make the pressing running component 24 more stable when pressing against the inner wall of the pipeline, and evenly share the pressure from the running wheel 245.

[0082] In addition, the sprayer also includes a central control module, a data processing module, a travel control module, a spray control module and a data storage module. The central control module is responsible for overall control and coordination of the work of each submodule. It is like the brain of the entire sprayer, able to receive feedback from each module, and make decisions based on preset programs and algorithms to precisely control other modules; the data processing module is used to receive visual data from the camera 16 inside the liquid inlet spray component 1. This module has powerful data processing capabilities and can perform real-time analysis of the images captured by the camera 16, such as identifying defects on the inner wall of the pipeline, detecting the degree of spray coverage, etc.; the travel control module is used to control the movement of the travel component 2, including forward, backward, stop and other functions. The travel control module can accurately control the speed and direction of the drive motor 244 according to the instructions of the central control module, thereby achieving The walking component 2 moves precisely in the pipeline; the spraying control module is used to control the spraying process of the liquid inlet spraying component 1, including spraying time, spraying pressure, spraying amount, etc. The spraying control module can adjust the speed of the reduction motor 11, the liquid inlet flow rate of the liquid inlet hose 17 and other parameters according to the size of the pipeline, the condition of the inner wall and the preset spraying requirements to achieve uniform spraying; the data storage module is used to record the data and images during the spraying process for subsequent analysis and quality tracking. The data storage module has a large-capacity storage space and can save various data in the spraying process for a long time, such as the change curve of the spraying pressure over time, images of different positions on the inner wall of the pipeline, etc. These data are of great significance for evaluating the spraying quality and improving the spraying process.

[0083] In actual use, the driving motor 244 is first started. The driving motor 244 starts to run according to the instruction of the walking control module, driving the walking wheel 245 to rotate, so that the walking component 2 moves in the pipeline. At the same time, the distance between the first mounting seat 21 and the second mounting seat 22 is adjusted by the stepping cylinder 23. The stepping cylinder 23 accurately adjusts the stroke according to the inner diameter of the pipeline under the control of the central control module, so that the walking wheel 245 that presses against the walking component 24 presses against the inner wall of the pipeline to ensure the stability of walking. The liquid inlet hose 17 transports the spray liquid to the five-way pipe 12, and then sprays it from the spray nozzle 14 through the liquid guide pipe 13 to spray the inner wall of the pipeline. The camera 16 takes real-time photos of the inner wall of the pipeline. The data processing module receives these visual data and analyzes and processes them. The central control module adjusts the movement of the walking component 2 and the spraying process of the liquid-inlet spraying component 1 through the walking control module and the spraying control module according to these data. For example, if it is found that a certain area is sprayed unevenly, the central control module can adjust the spraying parameters of the spray nozzle 14 through the spraying control module, or adjust the moving speed of the walking component 2 through the walking control module to achieve uniform spraying. The data storage module records the data and images during the spraying process for subsequent analysis and quality tracking. After the spraying is completed, the technician can evaluate the spraying quality by viewing the data and images in the data storage module, and make improvements to possible problems.
