Description

Technical Field

[0001] The present invention relates to the technical field of coating equipment, and particularly to a surface coating equipment for pipe supports and hangers applied to harsh environments. Background Art

[0002] Pipe supports and hangers are key components in a pipe system, mainly playing roles such as load-bearing, shock absorption and noise reduction, displacement / thermal compensation, pipe protection, and optimizing pipe layout. Reference can be made to the relevant content in Publication No.: CN111550635A, CN114165646A, and CN107606318A.

[0003] Further explanation: The support and hanger essentially belong to a metal structure, and combined with the layout environment of the pipe, such as harsh environments like boiler rooms with humid and hot problems, large-channel environments with high-speed impurity-containing airflow problems, etc. In such environments, water, high-speed airflow, and temperature changes will accelerate the corrosion degree and surface oxidation embrittlement degree of the support and hanger, ultimately directly affecting the above-mentioned effects of load-bearing, protection, shock absorption, etc. For this, the electroplating principle with lower cost and simplified process can be adopted;

[0004] However, it still needs to be further explained: Theoretically, the inner wall position of the support and hanger is in contact with the pipe, while the outer wall is exposed to the layout environment. There are differences in the environmental impacts on the two outer walls, so two different electroplating layer materials need to be selected. If a step-by-step electroplating process is adopted, the process cycle is relatively long, and processes such as cleaning, disassembly, and installation of shielding structures need to be added. Therefore, the present invention proposes a solution. Summary of the Invention

[0005] The purpose of the present invention is to provide a surface coating equipment for pipe supports and hangers applied to harsh environments. For the electroplating process of pipe supports and hangers, due to the selection of electroplating materials for the inner wall and outer wall according to the environment, the overall electroplating process is complicated, and a step-by-step shielding electroplating method needs to be adopted, which prolongs the process cycle.

[0006] The purpose of the present invention can be achieved through the following technical solutions: A surface coating equipment for pipe supports and hangers applied to harsh environments should include a whole-line platform assembly in the electroplating process of pipe supports and hangers. The whole-line platform assembly includes a standby position, an electrolysis position, and a cleaning position. Lifting support assemblies are provided in the standby position, the electrolysis position, and the cleaning position, and tanks are also provided in the electrolysis position and the cleaning position;

[0007] In the lifting support assembly, a plurality of independently arranged independent liquid columns are installed along the linear direction. The pipe support and hanger are placed on the outer wall position of the independent liquid column. A cavity is opened in the inner position of the independent liquid column, and a return liquid chamber is provided between the outer wall of the independent liquid column and the pipe support and hanger. A water port is provided between the cavity and the return liquid chamber.

[0008] Further set as: a crane structure, a water pump assembly and a power supply assembly are further provided in the whole line platform assembly. The water pump assembly is used to inject or discharge the electrolyte medium into the cavity and the pool body. The crane structure is used to change the setting position of the lifting bracket assembly in the standby position, the electrolysis position and the cleaning position.

[0009] Further set as: each pipe support hanger on the independent liquid column is in series connection.

[0010] Further set as: a first-order liquid pipe corresponding to the cavity is installed at the lower side position of the lifting bracket assembly, and a mounting bracket is installed at the upper end position of the lifting bracket assembly. A driving assembly is installed on the mounting bracket, and a liquid pipe insertion component corresponding to the upper end position of the cavity is installed at the output shaft position of the driving assembly.

[0011] Further set as: guiding mounting plates arranged vertically are installed at the two sides of the lifting bracket assembly corresponding to the independent liquid column. Glue injection mounting boxes are symmetrically installed on the guiding mounting plates along the placing direction of the pipe support hanger. An electromagnetic energizing assembly is arranged inside the glue injection mounting box, and a glue injection permanent magnet block corresponding to the electromagnetic energizing assembly is arranged in the guiding mounting plate.

[0012] Further set as: the glue injection permanent magnet block is slidably connected in the guiding mounting plate along the placing direction of the pipe support hanger, and an L-shaped protrusion corresponding to the pipe support hanger is arranged at the lower end position of the glue injection permanent magnet block.

[0013] Further set as: a rubber sealing ring is installed on the outer wall of the independent liquid column corresponding to the pipe support hanger.

[0014] Further set as: the lower side position of the return liquid bin is inclined downward along the direction pointing to the cavity.

[0015] The present invention has the following beneficial effects:

[0016] 1. Aiming at the structural characteristics of the pipe support hanger and to meet its electroplating requirements in different application environments, on the basis of the conventional electroplating method, it is optimized and improved. Based on the independent liquid column, multiple substrates (pipe support hangers) can be placed on a single independent liquid column, and a cavity for flowing electrolyte medium is opened inside the independent liquid column. When the whole independent liquid column is put into the electrolyte medium environment, the inner and outer sides of the substrate (pipe support hanger) can be respectively exposed to two different electrolysis environments, and the independent liquid column is used as a common cathode to form two independent electrolysis current circuits with two different electrolyte medium environments, so that the electroplating requirements on both sides of the substrate (pipe support hanger) can be completed at one time. Compared with the conventional masking electroplating method, the electroplating working hours can be shortened by more than half through the synchronous electroplating method;

[0017] 2. Based on the above content, the key content of the present invention lies in the independent liquid column. On the basis of maintaining the independent liquid column as an independent cathode, a magnetic drive process of suction / repulsion is first added for the picking and placing actions of the substrate (pipe support and hanger). Specifically, it is based on the electromagnetic energization component and the injection glue electromagnetic block. The purpose is to ensure that the substrate (pipe support and hanger) is completely attached to the surface position of the independent liquid column, and a static sealing method is adopted to avoid cross-contamination of the electrolytes in the two electrolyte media, which may affect the electroplating effect. In addition, the structure of the liquid return chamber is restricted for the flow process of the electrolyte medium in the cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0027] Embodiment 1: For the electroplating process of the pipeline suspension bracket, because the electroplating materials for the inner wall and the outer wall are selected according to the environment, the overall electroplating process is complicated, and the step-by-step masking electroplating method needs to be adopted to extend the process cycle. Therefore, the following technical solution is proposed:

[0028] Refer to Figures 1 to 6 , in the surface coating equipment for the pipeline support and hanger applied in harsh environments in this embodiment, in the electroplating process of the pipeline support and hanger, it includes a whole-line platform assembly 1. The whole-line platform assembly 1 includes a standby position 101, an electrolysis position 102, and a cleaning position 103. Lifting bracket assemblies 3 are provided in the standby position 101, the electrolysis position 102, and the cleaning position 103, and tanks 2 are also provided in the electrolysis position 102 and the cleaning position 103;

[0029] A plurality of independently arranged independent liquid columns 7 are installed in the lifting bracket assembly 3 along the linear direction. The pipeline support and hanger are placed at the outer wall position of the independent liquid column 7. A cavity is opened in the inner position of the independent liquid column 7, and a liquid return chamber 701 is provided between the outer wall of the independent liquid column 7 and the pipeline support and hanger. A water port is provided between the cavity and the liquid return chamber 701. A rubber sealing ring is installed at the outer wall position of the independent liquid column 7 corresponding to the pipeline support and hanger. The lower side position of the liquid return chamber 701 is inclined downward along the direction pointing to the cavity.

[0030] Basic principle: Referring to Figure 4 the structural shape of the pipeline support and hanger in, its inner wall position fits completely with the pipeline, and its outer wall position is exposed to the environment. Therefore, a protective layer is mainly electroplated on its surface position. However, the capabilities of the electroplating layers on the inner and outer sides are different. Therefore, two electroplating layers need to be electroplated on the inner and outer sides of the pipeline suspension bracket. The simplest method is to use the masking electroplating method. If electroplating is required for its inner side position, then an insulating material needs to be pasted on its outer side position to avoid being electroplated, and then electroplating is carried out on the outer side position in this way. The conventional electroplating time is relatively long. If this kind of masking method is used for operation, it will take more than twice the working hours;

[0031] Therefore, the present invention proposes a structure regarding the independent liquid column 7 for this problem, as Figure 6As shown in the figure, the outer diameter of the independent liquid column 7 is exactly equal to the inner diameter of the pipe support hanger, but there is a cavity inside it as a passage. The inside of the cavity mainly serves as the flow passage of the electrolyte medium. During the operation, each pipe support hanger is sequentially placed on the outer wall of the independent liquid column 7, and then the independent liquid column 7 is directly put into the pool body 2. Finally, different types of electrolyte media are injected into both the pool body 2 and the inside of the cavity.

[0032] It can be directly understood that the outer wall position of the pipe support hanger is exposed to the electrolyte medium environment inside the pool body 2, while the inner wall position of the pipe support hanger is exposed to the electrolyte medium environment in the cavity. According to the electrolysis principle, during the power-on process, the plating ions in the electrolyte medium are reduced and deposited on the surface of the substrate (pipe support hanger).

[0033] It should also be noted that: because in a single electroplating process, a closed-loop circuit is formed between the electrolyte and the substrate (pipe support hanger). First, it is necessary to ensure that each substrate (pipe support hanger) is connected in series. However, the key content of the present invention is that the electroplating process on both outer walls of the substrate (pipe support hanger) can be completed simultaneously. In the present invention, the independent liquid column 7 is used as a conductor. It should be emphasized that the independent liquid column 7 is used as a common cathode, and the electrolyte media inside the pool body 2 and inside the cavity are respectively connected to form independent anodes, forming two sets of electrolysis circuits. Thus, referring to the electroplating principle, electroplating layers with corresponding thicknesses and corresponding types can be formed on the inner wall position and the outer wall position of the substrate (pipe support hanger). This part is the key content of the present invention. The electroplating process on both sides of the substrate (pipe support hanger) can be completed in a single electroplating process, directly shortening the working hours in the conventional electroplating process.

[0034] It should be added that: for the electroplating method proposed in this embodiment, attention should also be paid to parameters such as independent current loop control, electrolyte temperature / concentration, etc. This part belongs to the process control part and will not be elaborated in this embodiment.

[0035] Embodiment 2: Based on the basic principle in Embodiment 1, a supplementary description of the overall operation process is given:

[0036] The integrated line platform assembly 1 is also provided with a crane structure, a water pump assembly and a power supply assembly. The water pump assembly is used to inject or discharge the electrolyte medium into the cavity and the tank body 2. The crane structure is used to change the installation position of the lifting support assembly 3 in the standby position 101, the electrolysis position 102 and the cleaning position 103. Each pipe support hanger on the independent liquid column 7 is in series connection. A first-order liquid pipe corresponding to the cavity is installed at the lower end position of the lifting support assembly 3, and a mounting bracket 4 is installed at the upper end position of the lifting support assembly 3. A driving assembly 5 is installed on the mounting bracket 4, and a liquid pipe insertion assembly 6 corresponding to the upper end position of the cavity is installed at the output shaft position of the driving assembly 5. Guide mounting plates 8 arranged vertically are installed at both sides of the lifting support assembly 3 corresponding to the independent liquid column 7;

[0037] The guide mounting plates 8 are symmetrically provided with glue injection mounting boxes 9 along the placement direction of the pipe support hangers. An electromagnetic energization assembly 10 is arranged inside the glue injection mounting boxes 9. Glue injection permanent magnets 11 corresponding to the electromagnetic energization assembly 10 are arranged in the guide mounting plates 8. The glue injection permanent magnets 11 are slidably connected in the guide mounting plates 8 along the placement direction of the pipe support hangers, and an L-shaped protrusion corresponding to the pipe support hangers is arranged at the lower end position of the glue injection permanent magnets 11.

[0038] Solution description: In the first embodiment, the electroplating method proposed by the present invention is mainly introduced, but the specific operation process refers to Figure 1 The following explanations are made:

[0039] The essence of the integrated line platform assembly 1 in the present invention belongs to the plant layout. Because the electroplating time is relatively long, and as Figure 4 shown, one electroplating process can meet the electroplating requirements of multiple substrates (pipe support hangers), so standby positions 101, electrolysis positions 102 and cleaning positions 103 are added. There are tank bodies 2 in the electrolysis position 102 and the cleaning position 103. The tank body 2 in the electrolysis position 102 is mainly used to hold a certain type of electrolyte, while the tank body 2 in the cleaning position 103 is mainly used to hold cleaning water for removing the electrolyte residues on both side surfaces of the substrate (pipe support hanger), and the standby position 101 is mainly used for the process of taking and placing the substrate (pipe support hanger) in the independent liquid column 7;

[0040] This process can be carried out manually or by using automated equipment, which is not described in the present invention. Secondly, the crane structure is used to meet the transfer requirements in the standby position 101, the electrolysis position 102 and the cleaning position 103. For example, the standby position 101 is transferred to the electrolysis position 102 for electroplating, and then the electrolysis position 102 is sent to the cleaning position 103 for cleaning. After cleaning, it is sent back to the standby position 101 for taking and placing. The following supplementary explanations are required for this process:

[0041] Solution one: Refer to Figure 5, when picking and placing workpieces, it is necessary to ensure that each base body (pipe support and hanger) is exactly aligned with the liquid return bin 701. For this purpose, an injection-molded permanent magnet block 11 is added. When the electromagnetic energization assembly 10 is energized, a repulsive force or an attractive force is formed with the injection-molded permanent magnet block 11. Taking the placement action as an example, first, it is necessary to install the placement sequence from bottom to top. For this, first, the injection-molded permanent magnet block 11 at the lowest layer position generates a repulsive force with the electromagnetic energization assembly 10, and ensures that the two injection-molded permanent magnet blocks 11 approach the base body (pipe support and hanger) simultaneously. What needs to be ensured in this process is:

[0042] First, it is necessary to ensure that the upper side position of the injection-molded permanent magnet block 11 is flush with the inner wall of the guide mounting plate 8. However, the main function of the L-shaped protrusion is to limit the placement position of each base body (pipe support and hanger). Finally, after the base body (pipe support and hanger) reaches the specified position, the repulsive force between the injection-molded permanent magnet block 11 and the electromagnetic energization assembly 10 is increased again to make the two closely fit. Its essence is to ensure that the inner wall of the base body (pipe support and hanger) completely fits on the outer wall position of the independent liquid column 7, and place them in sequence according to this order;

[0043] It should be added that: because there are two electrolyte media in the electroplating method of the present invention, a rubber sealing ring is added to the outer wall position of the independent liquid column 7 corresponding to the liquid return bin 701 to prevent cross-contamination of the two electrolyte media and affect the electroplating process;

[0044] Secondly, because the injection-molded permanent magnet block 11 and the electromagnetic energization assembly 10 are exposed in the electrolyte medium, in order to avoid being affected by electroplating, injection molding treatment is carried out on the two, so that their outer walls are completely wrapped with insulating sealant and are in an insulating and non-conductive state with the electrolyte medium, and it will not affect the magnetic transmission principle between the injection-molded permanent magnet block 11 and the electromagnetic energization assembly 10;

[0045] Solution 2: As Figure 6 described, the upper and lower ends of the cavity inside the independent liquid column 7 are both in an open state. Therefore, a first-order liquid pipe corresponding to the lower end of the cavity is installed at the lower end position of the lifting support assembly 3. However, the upper end position of its cavity forms an opening and closing structure through the liquid pipe insertion assembly 6. The essence of the liquid pipe insertion assembly 6 is a second-order liquid pipe connected by a fixing plate, and the fixing plate is moved up and down by the driving assembly 5. When the liquid pipe insertion assembly 6 moves down, the second-order liquid pipe is directly inserted into the upper end position of the cavity to ensure the flow of the electrolyte medium inside the cavity;

[0046] Solution 3: Solution 2 mainly focuses on the electrolysis requirements in the electrolysis position 102. After the overall lifting support assembly 3 is placed in the tank body 2 in the electrolysis position 102, the substrate (pipe support and hanger) is exposed to the electrolyte medium in the tank body 2. After accommodation, another electrolyte medium is injected into the cavity through the second-order liquid pipe. After the electroplating operation is completed in the electrolysis position 102, the electrolyte in the tank body 2 can be retained or replaced. The key lies in: it is necessary to directly discharge the electrolyte medium in the cavity. For this, it is necessary to ensure that the first-order liquid pipe and the second-order liquid pipe can be freely disassembled and assembled with the water pump assembly, and the water pump assembly is mainly used for injecting / discharging the electrolyte medium;

[0047] Solution 4: Supplementary description for Solution 3: Since it is necessary to ensure the natural outflow of the electrolyte medium in the liquid return tank 701, it is necessary to further restrict the structural limitation of the lower side position of the liquid return tank 701 so that it is inclined in the direction close to the cavity. Thus, in the natural state, the electrolyte medium in the liquid return tank 701 naturally flows back into the cavity.

[0048] In summary: For the substrate of the pipe support and hanger to meet the electroplating requirements in different application environments, the overall electroplating method is optimized and improved. Its essence is based on the conventional electroplating principle. The difference is that: a synchronous electroplating method is formed for the inner wall and outer wall positions of the pipe support and hanger. One electroplating process can meet the different electroplating requirements on both sides. Compared with the conventional masking electroplating method, the electroplating working hours can be shortened by half. For this, the key structure of the independent liquid column is proposed. One independent liquid column can meet the electroplating requirements of multiple substrates, and the sealing structure and the magnetic drive structure are synchronously added to ensure that the substrate fully adheres to the surface position of the independent liquid column, and to avoid cross-contamination of the electrolyte and affect the electroplating effect when the substrate is in two electrolyte media.
