Description

Technical Field

[0001] This utility model relates to the field of plasma spraying equipment technology, and in particular to a plasma spraying equipment that is convenient for outdoor operations. Background Technology

[0002] Plasma spraying is a material surface treatment technology that uses the high temperature of a plasma arc to heat powder materials to a molten or semi-molten state, and then sprays them onto the surface of the treated workpiece with the help of a high-speed plasma jet to form a coating with specific properties (such as wear resistance, corrosion resistance, heat insulation, and insulation).

[0003] Most plasma spraying is carried out in a highly controlled indoor environment to avoid the impact of airborne dust and contaminants on the coating. Temperature and wind speed in the spraying environment also need to be controlled. When the workpiece being sprayed is large, cannot be moved, or the cost of disassembly and transportation is extremely high, the spraying equipment must be moved to the site for outdoor operation.

[0004] However, plasma spraying equipment requires temporary sheds / tents to be set up when working outdoors, which is inconvenient. Utility Model Content

[0005] In view of this, it is necessary to provide a plasma spraying equipment that is convenient for outdoor operations, so as to solve the problem that plasma spraying equipment needs to be temporarily set up in sheds / tents when working outdoors, which is inconvenient.

[0006] This utility model provides a plasma spraying device suitable for outdoor operations, including a carrier chamber, a plasma spraying component, an air conditioning component, an annular frame, and a sealing component. The outer wall of the carrier chamber has a connection port. The plasma spraying component is installed inside the carrier chamber and has a movable spraying end. The air conditioning component is installed inside the carrier chamber and is used to regulate air quality. One opening of the annular frame is connected to the connection port of the carrier chamber, and the other side of the annular frame can be folded or unfolded to adjust the size of the opening on the other side. The sealing component includes a first covering layer and a second covering layer. The first covering layer wraps around the annular frame, and the second covering layer is connected to the side of the first covering layer away from the carrier chamber. The second covering layer has a spraying nozzle for close contact with the workpiece. A sealed cavity is formed between the carrier chamber, the first covering layer, the second covering layer, and the workpiece.

[0007] Furthermore, the plasma spraying assembly includes a power supply, a control cabinet, a spray gun, a powder feeder, a gas supply system, and a robotic arm. The robotic arm is installed inside the carrier chamber, and the spray gun is installed at the operating end of the robotic arm. The spray gun is connected to the powder feeder and the gas supply system via a hose, and the power supply is electrically connected to the spray gun, powder feeder, gas supply system, and robotic arm via the control cabinet.

[0008] Furthermore, the bottom of the plasma spraying assembly is slidably connected to the carrier chamber via a slider, the slider being used to drive the plasma spraying assembly to move in a direction closer to or further away from the connection port.

[0009] Furthermore, the sliding component includes a guide rail, a slider, a lead screw, and a motor. The guide rail is fixedly disposed on the inner wall of the carrier chamber. The plasma spraying assembly is slidably connected to the guide rail via the slider. The motor is fixedly connected to the carrier chamber. The output end of the motor is connected to the lead screw. The lead screw is rotatably connected to the carrier chamber. The lead screw is engaged with a threaded hole on the plasma spraying assembly.

[0010] Furthermore, the annular frame includes multiple support rods, which are arranged sequentially along the circumference of the connection port. One end of each support rod is hinged to the connection port of the bearing chamber, and the other end of each support rod is used to rest on the workpiece.

[0011] Furthermore, the first covering layer is a winding layer, which is arranged around a plurality of the support rods.

[0012] Furthermore, the second coating layer is annular, the outer wall of the second coating layer is connected to the first coating layer, and the inner wall of the second coating layer is in sealed contact with the workpiece.

[0013] Furthermore, the connection between the first coating layer and the second coating layer is made by adhesive, and the second coating layer and the workpiece are also made by adhesive.

[0014] Furthermore, both the first and second covering layers are flexible structures.

[0015] Furthermore, the air conditioning assembly includes an air conditioner, a humidifier, and a dust collector installed within the carrying compartment.

[0016] Compared with existing technologies, this method pre-determines the part of the workpiece to be repaired, allowing the annular frame to expand to the size of the opening on the side away from the support chamber, covering the part of the workpiece to be repaired. The opening of the annular frame is placed on the part of the workpiece to be repaired. The first covering layer is installed on the outside of the annular frame, and the second covering layer connects the first covering layer and the workpiece, with the spray nozzle of the second covering layer in close contact with the workpiece. At this time, a sealed cavity is formed between the support chamber, the first covering layer, the second covering layer, and the workpiece. The air conditioning component regulates the air quality in the sealed cavity to ensure that the plasma spraying component can successfully achieve the spraying effect, making it suitable for outdoor operations.

Detailed Implementation

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0019] like Figure 1 As shown, this utility model provides a plasma spraying device suitable for outdoor operations, including a carrier chamber 100, a plasma spraying component 200, an air conditioning component 300, an annular frame 400, and a sealing component 500; the outer wall of the carrier chamber 100 is provided with a connection port 110; the plasma spraying component 200 is installed inside the carrier chamber 100 and has a movable spraying end; the air conditioning component 300 is installed inside the carrier chamber 100 for regulating air quality; the opening on one side of the annular frame 400 is connected to the connection port 110 of the carrier chamber 100. 10. The other side of the annular frame 400 can be folded or unfolded to adjust the size of the opening on the other side; the sealing assembly 500 includes a first covering layer 510 and a second covering layer 520. The first covering layer 510 is disposed around the annular frame 400. The second covering layer 520 is connected to the side of the first covering layer 510 away from the bearing chamber 100. The second covering layer 520 is provided with a spray nozzle 50a for tightly adhering to the workpiece M. A sealed cavity is formed between the bearing chamber 100, the first covering layer 510, the second covering layer 520 and the workpiece M.

[0020] During implementation, the part of workpiece M to be repaired is determined in advance, and the side of the annular frame 400 away from the bearing chamber 100 is unfolded so that the opening size can cover the part of workpiece M to be repaired. The opening of the annular frame 400 is placed on the part of workpiece M to be repaired. The first covering layer 510 is installed on the outside of the annular frame 400, and the second covering layer 520 connects the first covering layer 510 and the workpiece M, and the spray nozzle 50a of the second covering layer 520 is in close contact with the workpiece M. At this time, a sealed cavity is formed between the bearing chamber 100, the first covering layer 510, the second covering layer 520 and the workpiece M. The air conditioning component 300 regulates the air quality in the sealed cavity to ensure that the plasma spraying component 200 can successfully achieve the spraying function, which is suitable for outdoor operation.

[0021] In this embodiment, the carrier chamber 100 is a box structure, which is used to install the plasma spraying component 200 and the air conditioning component 300. Its outer wall is provided with a connection port 110, which is connected to the part of the workpiece M to be repaired through the provided annular frame 400 and sealing component 500, forming a sealed cavity to avoid the external environment from affecting the spraying environment.

[0022] In one embodiment, the carrier compartment 100 can be installed on the vehicle body, and the transfer of the carrier compartment 100 can be achieved by moving the vehicle body.

[0023] It should be noted that the aforementioned carrier chamber 100 should adopt a structure with good sealing performance to prevent outside air from entering the carrier chamber 100 and affecting the spraying operation.

[0024] In this embodiment, the plasma spraying assembly 200 is installed inside the carrier chamber 100 and has a movable spraying end.

[0025] In one embodiment, the plasma spraying assembly 200 includes a power supply, a control cabinet, a spray gun, a powder feeder, a gas supply system, and a robot arm. The robot arm is installed inside the carrier chamber 100, and the spray gun is installed at the operating end of the robot arm. The spray gun is connected to the powder feeder and the gas supply system via a hose, and the power supply is electrically connected to the spray gun, the powder feeder, the gas supply system, and the robot arm via the control cabinet.

[0026] It is understood that the plasma spraying component 200 is a conventional structure that can be conceived by those skilled in the art, and its structure is not the part that is improved in this application, so it will not be elaborated or explained in detail here.

[0027] To facilitate an increase in the spraying range, in one embodiment, the bottom of the plasma spraying assembly 200 is slidably connected to the carrier chamber 100 via a slider, which is used to drive the plasma spraying assembly 200 to move in a direction closer to or further away from the connection port 110.

[0028] In this embodiment, the sliding component includes a guide rail, a slider, a lead screw, and a motor. The guide rail is fixedly installed on the inner wall of the support chamber 100. The plasma spraying assembly 200 is slidably connected to the guide rail via the slider. The motor is fixedly connected to the support chamber 100. The output end of the motor is connected to the lead screw. The lead screw is rotatably connected to the support chamber 100. The lead screw is engaged with a threaded hole on the plasma spraying assembly 200.

[0029] Of course, in other preferred embodiments, the sliding member can also be replaced by a structure in the form of a linear motor, an electric push rod, etc., so that the spraying end of the plasma spraying assembly 200 can move to any position within the annular frame 400.

[0030] The air conditioning assembly 300 in this embodiment includes an air conditioner 310, a humidifier 320, and a dust collector 330 installed in the carrier compartment 100. It is understood that the air conditioner 310, humidifier 320, and dust collector 330 are all conventional household appliance structures that can be conceived by those skilled in the art, and will not be elaborated or described in detail here.

[0031] Moisture in the air can react with the high-temperature sprayed particles, oxidizing the coating or causing it to crack. The powder itself can also become damp and clump together, causing poor powder delivery. Therefore, this application uses a humidifier 320 to control the humidity inside the sealed cavity.

[0032] Among them, pollutants such as dust, moisture, and oil in the air can seriously contaminate the sprayed powder and the substrate surface, causing the coating to have pores and inclusions, resulting in a sharp decrease in bonding strength or even complete failure. Therefore, this application uses a dust collector 330 to collect dust and other pollutants in the sealed cavity.

[0033] In this embodiment, the annular skeleton 400 is used to support the sealing assembly 500 to form a sealing cavity with an adjustable opening size, thereby adapting to workpieces M of different shapes and sizes.

[0034] In one embodiment, the annular frame 400 includes a plurality of support rods arranged sequentially along the circumference of the connection port 110. One end of each support rod is hinged to the connection port 110 of the bearing chamber 100, and the other end of each support rod is used to rest on the workpiece M.

[0035] When multiple support rods rotate in opposite directions, the annular frame 400 unfolds, and the diameter of the opening on the side away from the bearing chamber 100 increases. When multiple support rods rotate in opposite directions, the annular frame 400 retracts, and the diameter of the opening on the side closer to the bearing chamber 100 decreases.

[0036] Understandably, the ends of the multiple support rods away from the bearing chamber 100 rest on the workpiece M, and the support rods are prevented from shifting by the connecting force of the sealing assembly 500. Of course, the above fixing method is not reliable. In this case, the support rods can be fixed by setting a top rod at the bottom of the support rod. The bottom end of the top rod contacts the ground, and the top end of the top rod is detachably connected to the support rod (e.g., by means of a pin, connecting screw, etc.).

[0037] The sealing assembly 500 in this embodiment includes a first covering layer 510 and a second covering layer 520. The first covering layer 510 is disposed around the annular skeleton 400. The second covering layer 520 is connected to the side of the first covering layer 510 away from the bearing chamber 100. The second covering layer 520 is provided with a spray nozzle 50a for tightly adhering to the workpiece M. A sealing cavity is formed between the bearing chamber 100, the first covering layer 510, the second covering layer 520 and the workpiece M.

[0038] In one embodiment, the first covering layer 510 is a winding layer, which is coiled around multiple support rods. The first covering layer 510 is wound around the annular frame 400 by winding.

[0039] In one embodiment, the second covering layer 520 is annular, the outer wall of the second covering layer 520 is connected to the first covering layer 510, and the inner wall of the second covering layer 520 is in sealed contact with the workpiece M.

[0040] The first covering layer 510 and the second covering layer 520 are connected by adhesive, and the second covering layer 520 and the workpiece M are connected by adhesive. Alternatively, a zipper or other method can be used to connect the first covering layer 510 and the second covering layer 520.

[0041] It should be noted that both the first coating layer 510 and the second coating layer 520 are flexible structures. Furthermore, both the first coating layer 510 and the second coating layer 520 should possess good gas barrier properties, and can be made of materials such as polyethylene film. It is understood that the aforementioned first coating layer 510 and the second coating layer 520 are inexpensive and can be used as disposable structures.

[0042] Example 1, as Figure 2 As shown, when the part of the workpiece M to be repaired is a long strip structure M1, after the first covering layer 510 is installed, the long strip structure is passed through the opening of the annular frame 400 so that it extends into the interior of the annular frame 400. At this time, the second covering layer 520 is installed. The outer wall of the second covering layer 520 is connected to the end of the first covering layer 510. The inner wall of the second covering layer 520 forms a spray nozzle 50a and is in close contact with the outer wall of the long strip structure.

[0043] Example 2, as Figure 3As shown, when the part of workpiece M to be repaired is a planar structure M2, after the first covering layer 510 is installed, the part of workpiece M to be repaired is aligned with the opening of the annular frame 400. At this time, the second covering layer 520 is installed. The outer wall of the second covering layer 520 is connected to the end of the first covering layer 510, and the inner wall of the second covering layer 520 forms a spray nozzle 50a that is connected to the periphery of the part of workpiece M to be repaired.

[0044] Compared with the prior art: The part of the workpiece M to be repaired is determined in advance, and the side of the annular frame 400 away from the bearing chamber 100 is opened so that the opening can cover the part of the workpiece M to be repaired. The opening of the annular frame 400 is placed on the part of the workpiece M to be repaired. The first covering layer 510 is installed on the outside of the annular frame 400. The second covering layer 520 connects the first covering layer 510 and the workpiece M, and the spray nozzle 50a of the second covering layer 520 is in close contact with the workpiece M. At this time, a sealed cavity is formed between the bearing chamber 100, the first covering layer 510, the second covering layer 520 and the workpiece M. The air conditioning component 300 regulates the air quality in the sealed cavity to ensure that the plasma spraying component 200 can successfully achieve the spraying function, which is suitable for outdoor operation.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
