Description

Technical Field

[0001] This utility model relates to the field of corrosion protection construction, and in particular to a corrosion protection construction device for pressure vessels. Background Technology

[0002] A pressure vessel is a sealed container capable of withstanding pressure. Pressure vessels have extremely wide applications, playing a vital role in many sectors including industry, civil engineering, military, and scientific research. They are most prevalent in the chemical and petrochemical industries, where they account for approximately 50% of all pressure vessels. Petrochemical pressure vessels are prone to corrosion and rust during prolonged use, necessitating anti-corrosion treatment.

[0003] For example, patent document CN116078587A discloses an anti-corrosion construction device for petrochemical pressure vessels, relating to the field of anti-corrosion construction technology. This invention includes a base plate, a fixed column fixedly mounted on the upper surface of the base plate, a servo motor fixedly mounted on the upper surface of the fixed column, a rotating rod fixedly connected to the output end of the servo motor via a coupling, a driving gear fixedly fitted on the outer surface of the rotating rod, a threaded rod rotatably connected between the inner walls of the fixed column, a driven gear fixedly fitted on the outer surface of the threaded rod, the driving gear and the driven gear meshing, a sliding groove formed on the side wall of the fixed column, and a worktable threadedly connected to the outer surface of the threaded rod. This invention solves the problem that existing anti-corrosion construction operations mostly involve manual spraying of anti-corrosion paint, requiring manual access via ladders or other means to spray from higher parts of the container, making it difficult to automatically adjust the worktable for spraying, resulting in time-consuming, labor-intensive, and inefficient anti-corrosion spraying.

[0004] In existing technologies, one step in the corrosion protection process of pressure vessels is to spray an anti-corrosion coating. However, due to the large size of large pressure vessels, manual spraying is not only time-consuming and labor-intensive, but also requires ladders or other devices for spraying operations at higher positions, which further slows down the spraying efficiency. In order to improve the spraying efficiency, a pressure vessel corrosion protection construction device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a corrosion protection construction device for pressure vessels in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A corrosion protection construction device for pressure vessels includes a main body, which includes a frame. Several wheels are rotatably connected to the bottom of the frame. A lifting assembly is installed on the top of the frame.

The adjustment mechanism includes a fixed telescopic frame, a sliding telescopic rod is slidably connected to the fixed telescopic frame, a telescopic drive assembly is installed inside the fixed telescopic frame, an adjustment motor is fixedly connected to the other end of the sliding telescopic rod, and a rotating bracket is fixedly connected to the output end of the adjustment motor. The spraying mechanism includes a paint storage assembly placed on one side of the frame. A conveying hose is fixedly connected to the top of the paint storage assembly, and a spray gun is fixedly connected to the other end of the conveying hose. The spray gun is pin-connected to the rotating bracket.

[0008] Preferably, the lifting assembly includes a fixed bracket fixedly connected to the middle of the top of the vehicle frame, a lifting motor fixedly connected to the top of the fixed bracket, a lifting screw rotatably connected to the middle of the fixed bracket, a guide rod fixedly connected to one side of the fixed bracket, a lifting bracket threadedly connected to the lifting screw, the lifting bracket and the guide rod being slidably connected, and the front side of the lifting bracket being fixedly connected to the fixed telescopic frame.

[0009] Preferably, the telescopic drive assembly includes a telescopic screw rotatably connected within a fixed telescopic frame, the telescopic screw being threadedly connected to a sliding telescopic rod, a driven bevel gear fixedly connected to the other end of the telescopic screw, a driving bevel gear rotatably connected to one side of the fixed telescopic frame, the driving bevel gear meshing with the driven bevel gear, a drive gear fixedly connected to the other end of the driving bevel gear, and a rack assembly fixedly connected to the front side of the fixed bracket, the rack assembly including two circumferentially symmetrically arranged racks, the two racks in the rack assembly being able to mesh with the front and rear sides of the drive gear respectively.

[0010] Preferably, the spraying mechanism further includes a material cylinder box fixedly connected to the other side of the top of the vehicle frame. The material cylinder box surrounds the paint storage assembly. The paint storage assembly includes a storage tank and a delivery pump. The output end of the delivery pump in the paint storage assembly is fixedly connected to a delivery hose. A first flip door is rotatably connected to one side of the material cylinder box. A limit block is fixedly connected to one side of the lifting bracket. The delivery hose passes through the limit block.

[0011] Preferably, the manned mechanism includes a manned box slidably connected to a fixed bracket, a second flip door rotatably connected to one side of the manned box, a plurality of first connecting holes opened on one side of the manned box, a plurality of second connecting holes opened on the other side of the lifting bracket, a connecting frame provided on the manned box, a plurality of pins fixedly connected to one side of the connecting frame, and the second connecting holes and the first connecting holes being connected through the pins on the connecting frame.

[0012] Preferably, the fixed bracket, the hopper, and the passenger compartment are made of hollow metal tubes and are configured as an outer wall truss.

[0013] The beneficial effects are as follows: by adjusting the coordination between the lifting component and the positioning mechanism, the spray gun is brought close to the predetermined construction surface of the pressure vessel. Then, the anti-corrosion coating is sprayed onto the pressure vessel through the spray gun. The wheels drive the frame to move, so that the spray gun sprays a part of the pressure vessel surface. After completion, the position of the spray gun is adjusted again to spray another part of the pressure vessel surface. After repeated reciprocating movements, the surface of the pressure vessel can be sprayed. Then, the worker removes the spray gun from the rotating bracket, stands in the personnel carrier and moves with the construction device to manually inspect the surface of the pressure vessel. In this way, by combining mechanical reciprocating spraying with manual inspection spraying, the spraying efficiency is improved while ensuring the spraying quality.

Therefore, they should not be construed as limitations on this utility model.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-7As shown, a corrosion protection construction device for pressure vessels includes a main body, which includes a frame 101. Several wheels 102 are rotatably connected to the bottom bearings of the frame 101. A lifting assembly is installed on the top of the frame 101. A spraying mechanism is installed on one side of the lifting assembly, and a personnel carrying mechanism is movably connected to the other side of the lifting assembly. An adjustment mechanism is installed at the front of the lifting assembly. The adjustment mechanism includes a fixed telescopic frame 301, and a sliding telescopic rod 302 is slidably connected to the fixed telescopic frame 301. Both the fixed telescopic frame 301 and the sliding telescopic rod 302 are rectangular. A telescopic drive is installed inside the fixed telescopic frame 301. The moving assembly, the sliding telescopic rod 302, has an adjusting motor 308 bolted to its other end. The output end of the adjusting motor 308 is fixedly connected to a rotating bracket 309. The spraying mechanism includes a paint storage assembly 203 placed on one side of the frame 101. A conveying hose 204 is sealed and fixedly connected to the top of the paint storage assembly 203. A spray gun 205 is sealed and fixedly connected to the other end of the conveying hose 204. The spray gun 205 is pinned to the rotating bracket 309. In the prior art, one step in the pressure vessel anti-corrosion process is spraying an anti-corrosion coating. However, due to the large size of large pressure vessels, this is usually done manually. Spraying is not only time-consuming and labor-intensive, but also requires ladders and other equipment for spraying operations at higher positions, further slowing down the spraying efficiency. To improve spraying efficiency, a pressure vessel anti-corrosion construction device is proposed. During anti-corrosion construction, the operator adjusts the coordination of the lifting component and the positioning mechanism to bring the spray gun 205 close to the predetermined construction surface of the pressure vessel. Then, the motor 308 drives the rotating bracket 309 to rotate, which in turn rotates the spray gun 205 to align with the pressure vessel surface. The paint storage component 203 pumps the anti-corrosion paint into the delivery hose 204, and then the anti-corrosion paint is sprayed onto the surface through the spray gun 205. On the pressure vessel, wheels 102 drive the frame 101 to move, so that the spray gun 205 sprays on the surface of the pressure vessel. After completing the spraying of a part of the area, the position of the spray gun 205 is adjusted to spray another part of the pressure vessel surface. After repeated reciprocating movements, the surface of the pressure vessel can be sprayed. Then, the workers remove the spray gun 205 from the rotating bracket 309, stand in the manned mechanism and move with the construction device to manually inspect the surface of the pressure vessel. In this way, the combination of mechanical reciprocating spraying and manual inspection spraying improves the spraying efficiency while ensuring the spraying quality.

[0029] The lifting assembly includes a fixed bracket 103 fixedly connected to the middle of the top of the frame 101. A lifting motor 104 is fixedly connected to the top of the fixed bracket 103. A lifting screw 105 is rotatably connected to the middle of the fixed bracket 103. A guide rod 106 is fixedly connected to one side of the fixed bracket 103. A lifting bracket 107 is threadedly connected to the lifting screw 105. The lifting bracket 107 is slidably connected to the guide rod 106. The front side of the lifting bracket 107 is fixedly connected to the fixed telescopic frame 301. The lifting motor 104 drives the lifting screw 105 to rotate. The lifting screw 105 drives the lifting bracket 107 to rise and fall through the threaded connection. During the rising and falling of the lifting bracket 107, the guide rod 106 ensures that the lifting bracket 107 will not deflect. The lifting bracket 107 drives the fixed telescopic frame 301 to rise and fall.

[0030] The telescopic drive assembly includes a telescopic screw 307 rotatably connected within a fixed telescopic frame 301. The telescopic screw 307 is threadedly connected to a sliding telescopic rod 302. A driven bevel gear 306 is fixedly connected to the other end of the telescopic screw 307. A driving bevel gear 305 is rotatably connected to one side of the fixed telescopic frame 301, meshing with the driven bevel gear 306. A drive gear 304 is fixedly connected to the other end of the driving bevel gear 305. A rack assembly 303 is fixedly connected to the front side of the fixed bracket 103. The rack assembly 303 includes two circumferentially symmetrically arranged racks. The two racks in the rack assembly 303 can mesh with the front and rear sides of the drive gear 304, respectively. Since the pressure vessel is mostly cylindrical, to omit the adjustment steps, the process proceeds from bottom to top... This allows the sliding telescopic rod 302 to retract and then extend relative to the fixed telescopic frame 301. One end of the sliding telescopic rod 302 moves in an approximately circular arc. This function is achieved through two symmetrically arranged rack sets 303. The lifting bracket 107 drives the fixed telescopic frame 301 to rise and fall, and the fixed telescopic frame 301 drives the drive gear 304 to rise and fall. Since the drive gear 304 meshes with the rack set 303, the drive gear 304 rotates during the rising and falling process. The drive gear 304 drives the active bevel gear 305 to rotate, and the active bevel gear 305 drives the driven bevel gear 306 to rotate. The driven bevel gear 306 drives the telescopic screw 307 to rotate, and the telescopic screw 307 drives the sliding telescopic rod 302 to move. The sliding telescopic rod 302 drives the spray gun 205 to move.

[0031] The spraying mechanism also includes a material cylinder box 201 fixedly connected to the other side of the top of the frame 101. The material cylinder box 201 surrounds the paint storage component 203. The paint storage component 203 includes a storage tank and a delivery pump. The storage tank and the delivery pump are existing technologies, and their specific mechanisms will not be described in detail in this application. The output end of the delivery pump in the paint storage component 203 is fixedly connected to the delivery hose 204. The lower end of the delivery hose 204 is set in a spiral shape. A first flip door 202 is rotatably connected to one side of the material cylinder box 201. A limit block 206 is fixedly connected to one side of the lifting bracket 107. The limit block 206 plays the role of organizing the wire harness. The delivery hose 204 passes through the limit block 206. The delivery pump in the paint storage component 203 delivers the anti-corrosion paint in the storage tank into the delivery hose 204.

[0032] The manned mechanism includes a manned container 401 slidably connected to a fixed bracket 103. A second flip door 402 is rotatably connected to one side of the manned container 401. Several first connecting holes 404 are opened on one side of the manned container 401, and several second connecting holes 405 are opened on the other side of the lifting bracket 107. A connecting frame 403 is provided on the manned container 401, and several pins are fixedly connected to one side of the connecting frame 403. The second connecting holes 405 and the first connecting holes 404 are connected through the pins on the connecting frame 403. Mechanical reciprocating spraying is then performed. During the process, the connection frame 403 is disconnected from the first connection hole 404 and the second connection hole 405. In this way, when the lifting component is raised and lowered, it only loads the adjustment mechanism. When the division of labor is carried out for re-inspection and spraying, the connection frame 403 is pinned to the first connection hole 404 and the second connection hole 405. Then, the staff stands in the personnel box 401 and removes the spray gun 205 from the rotating bracket 309. The lifting component drives the personnel box 401 and the staff on it to rise and fall. In this way, the surface of the pressure vessel can be manually re-inspected.

[0033] The fixed support 103, the material cylinder box 201, and the personnel box 401 are made of hollow metal tubes and are set in the form of an outer wall truss. By using hollow metal tubes as raw materials and setting the support in the form of a truss, the weight of the device can be reduced while ensuring structural strength.

[0034] Working Principle: During anti-corrosion construction, the lifting motor 104 drives the lifting screw 105 to rotate. The lifting screw 105 drives the lifting bracket 107 to rise and fall through a threaded connection. During the rising and falling of the lifting bracket 107, the guide rod 106 ensures that the lifting bracket 107 does not deflect. The lifting bracket 107 drives the fixed telescopic frame 301 to rise and fall. The fixed telescopic frame 301 drives the drive gear 304 to rise and fall. Since the drive gear 304 meshes with the rack and pinion 303, the drive gear 304 rotates during the rising and falling process. The drive gear 304 drives the driving bevel gear 305 to rotate. The driving bevel gear 305 drives the driven bevel gear 306 to rotate. The driven bevel gear 306 drives the telescopic screw 307 to rotate. The telescopic screw 307 drives the sliding telescopic rod 302 to move. The sliding telescopic rod 302 drives the spray gun 205 to move. This allows the spray gun 205 to move. 05. Approaching the predetermined construction surface of the pressure vessel, the motor 308 drives the rotating bracket 309 to rotate. The rotating bracket 309 drives the spray gun 205 to rotate and align with the pressure vessel surface. The paint storage component 203 pumps the anti-corrosion paint into the delivery hose 204. Then, the anti-corrosion paint is sprayed onto the pressure vessel through the spray gun 205. The wheels 102 drive the frame 101 to move. In this way, the spray gun 205 sprays on the surface of the pressure vessel. After completing the spraying of a part of the area, the position of the spray gun 205 is adjusted to spray another area of ​​the pressure vessel surface. After repeated reciprocating movements, the surface of the pressure vessel can be sprayed. Then, the worker removes the spray gun 205 from the rotating bracket 309, stands in the manned mechanism and moves with the construction device to manually inspect the surface of the pressure vessel. In this way, the combination of mechanical reciprocating spraying and manual inspection spraying improves the spraying efficiency while ensuring the spraying quality.
