Description

Technical Field

[0001] The utility model relates to the technical field of anti-corrosion processing, in particular to an anti-corrosion spraying device for the surface of an elbow. Background Technique

[0002] Steel elbows are prone to oxidation by oxygen in the air when exposed in the air and rust is generated. Moreover, nitrogen oxides in the air will become weak acids when encountering water and react chemically with the surface of the steel pipe, which will corrode the steel pipe. Therefore, an anti-corrosion coating needs to be sprayed on the steel elbow before storage to prevent corrosion. By spraying the anti-corrosion coating, the contact between the corrosion medium and the steel elbow is blocked, so as to achieve the purpose of anti-corrosion.

[0003] The most common existing anti-corrosion coating spraying equipment for steel elbows is to spray the surface of the steel elbow by manual holding. This not only cannot ensure the stability of the nozzle and the elbow, but also easily causes spraying blind areas on the surface of the elbow. This method not only consumes a lot of manpower, but also the manually controlled spraying moving speed cannot be accurately maintained at a fixed moving speed, which easily causes problems such as low spraying rate and lack of accuracy and stability. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems of uneven spraying and slow efficiency in the spraying process of the existing anti-corrosion spraying device for the surface of an elbow, and to propose an anti-corrosion spraying device for the surface of an elbow.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An anti-corrosion spraying device for the surface of an elbow, including a box body with an open top. A driving motor and a pressure pump pipe for pressurizing and conveying anti-corrosion paint are respectively fixedly installed on both sides of the box body. A limiting component driven by the driving motor and used for supporting and fixing the elbow is arranged in the box body, and a spraying component for spraying anti-corrosion paint on the elbow through the pressure pump pipe is also arranged in the box body.

[0007] Preferably, a cover plate is hinged at the open top position of the box body, and a handle is bolted on the cover plate.

[0008] Preferably, the limiting component includes an installation turntable fixedly installed on the output end of the driving motor and located in the box body. A support rod corresponding to the open end of the elbow is integrally connected to the turntable, and a guiding long hole is opened in the support rod. A telescopic cylinder is fixedly installed on the installation turntable. A first slider fixedly connected to the output end of the telescopic cylinder is slidably sleeved at one end of the guiding long hole, and a second slider symmetrical to the first slider is slidably sleeved in the other end of the guiding long hole. A first connecting rod and a second connecting rod are respectively pin-installed on the first slider and the second slider and are rotatably connected;

[0009] An end stop mechanism supported by a support rod member is movably connected between the first connecting rod and the second connecting rod.

[0010] Preferably, the end stop mechanism includes a guide block fixedly installed in the long guide hole, and end stop long holes are provided in both the first connecting rod and the second connecting rod. A limit bolt is slidably sleeved in the end stop long hole. A synchronous connecting rod is fixedly connected between the two limit bolts. An expansion rod that slidably penetrates through the guide block is integrally connected to the synchronous connecting rod. A strong spring sleeved on the expansion rod is welded between the synchronous connecting rod and the guide block.

[0011] Preferably, the spraying assembly includes a conveying pipeline fixedly connected to the pressure pump pipe, and a high-pressure spray head corresponding to the elbow is provided on the conveying pipeline.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer to Figures 1 - 5 , an anti-corrosion spraying device for the surface of elbows, including a box body 1 with an open top. A cover plate 2 is hinged at the open top position of the box body 1, and a handle 3 is bolted on the cover plate 2, which can make the opening and closing more convenient during the process of replacing and taking out the elbows, and at the same time play a role in preventing the spraying dye from splashing out. A driving motor 4 and a pressurized pump pipe 5 for pressurizing and conveying anti-corrosion paint are respectively fixedly installed on both sides of the box body 1. An electromagnetic valve for controlling the flow of anti-corrosion paint is provided on the pressurized pump pipe 5, so that the anti-corrosion paint flows into the box body 1 through the pressurized pump pipe 5.

[0024] A limiting component driven by the driving motor 4 and used for supporting and fixing the elbow is arranged in the box body 1. The limiting component is located inside the box body 1. First of all, the limiting component includes an installation turntable 8 fixedly installed on the output end of the driving motor 4 and located inside the box body 1. The installation turntable 8 is connected to the driving motor 4 through a bearing. Under the driving action of the driving motor 4, the turntable 8 drives the fixed-position elbow to rotate, so that multiple angles of the surface of the elbow can correspond to the high-pressure spray head 7, ensuring the uniformity and comprehensiveness of spraying. A support rod member 9 corresponding to one end opening of the elbow is integrally connected to the turntable 8, and a guide long hole 10 is provided in the support rod member 9. A telescopic cylinder 11 is fixedly installed on the installation turntable 8, and the telescopic cylinder 11 is symmetrically arranged on the upper and lower sides of the support rod member 9. A first slider 12 fixedly connected to the output end of the telescopic cylinder 11 is slidably sleeved at one end of the guide long hole 10, and a second slider 13 symmetrical to the first slider 12 is slidably sleeved in the other end of the guide long hole 10. A first connecting rod 14 and a second connecting rod 15 are respectively pin-installed on the first slider 12 and the second slider 13 for rotational connection. It should be noted that a damping pad is rotatably installed at the connection end of the first connecting rod 14 and the second connecting rod 15 to increase the frictional resistance in contact with the inner wall of the elbow, ensuring the stability and firmness of the support of the elbow by the connection end when the first connecting rod 14 and the second connecting rod 15 are in the closed state;

[0025] Secondly, a limiting mechanism supported by a support rod member 9 is movably connected between the first connecting rod 14 and the second connecting rod 15. The limiting mechanism is located below the hinge of the first connecting rod 14 and the second connecting rod 15. The limiting mechanism includes a guide block 16 fixedly installed in the guide long hole 10. Limiting long holes 17 are provided in both the first connecting rod 14 and the second connecting rod 15. A limiting bolt 19 is slidably sleeved in the limiting long hole 17. The limiting bolt 19 can slide left and right along the limiting long hole 17 in the limiting long hole 17. A synchronous connecting rod 18 is fixedly connected between the limiting bolts 19. A telescopic rod 20 that slidably penetrates through the guide block 16 is integrally connected to the synchronous connecting rod 18. A strong spring 21 sleeved on the telescopic rod 20 is welded between the synchronous connecting rod 18 and the guide block 16. For specific reference, see the attached Figure 3 to the attached Figure 4 description. Further, by providing the telescopic rod 20 for limiting and supporting the synchronous connecting rod 18 on the support rod member 9, during the process of pressing and driving the first slider 12 at one side position, the synchronous connecting rod 18 can only perform vertical lifting movement due to the telescopic rod 20, ensuring that the first connecting rod 14 and the second connecting rod 15 are synchronously stressed.

[0026] A spraying assembly for spraying anti-corrosion paint on the elbow through a pressure pump pipe 5 is further provided in the box body 1. The spraying assembly includes a conveying pipeline 6 fixedly connected to the pressure pump pipe 5, and a high-pressure nozzle 7 corresponding to the elbow is provided on the conveying pipeline 6.

[0027] The high-pressure nozzle 7 includes two horizontally installed first nozzles 701 and one vertically installed second nozzle 702. Specifically, as shown in the attached Figure 5 description of the elbow structure. By providing the horizontally arranged first nozzles 701 and the vertically arranged second nozzle 702, the elbow can be subjected to all-round spraying processing, avoiding spraying blind spots.

[0028] It should be noted that the specific model specifications of the driving motor 4 and the pressure pump pipe 5 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0029] The functional principle of the present utility model can be described through the following operation mode:

[0030] In the initial state, the telescopic cylinder 11 is in the retracted state. One end of the elbow shown in the attached Figure 5 description is sleeved on the limiting component shown in the attached Figure 3 description;

[0031] The output end of the telescopic cylinder 11 pushes the first slider 12 outwards, driving the first slider 12 to move horizontally along the guide long hole 10, so that the first connecting rod 14 deflects towards the vertical direction with the first slider 12 as the fulcrum;

[0032] Since the first link 14 and the second link 15 are movably connected, and at the same time, the limiting bolt 19 is driven by the synchronous link 18 to move in the limiting long hole 17, the second link 15 performs a deflection movement synchronous with the first link 14;

[0033] During the closing process, the first link 14 and the second link 15 drive the damping pad to contact the inner wall of the elbow and fix one end of the elbow;

[0034] Control the driving motor 4 to start, and drive the elbow to rotate and adjust through the turntable 8 and the limiting component.

[0035] Control the opening of the pressure pump pipe 5 through the solenoid valve. The pressure pump pipe 5 conveys the anti-corrosion paint to the conveying pipeline 6, and the anti-corrosion paint is sprayed onto the surface of the elbow by the high-pressure nozzle 7. Among them, the first nozzle 701 sprays the longitudinal section of the elbow, and the second nozzle 702 sprays the transverse section of the elbow.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
