Description

Technical Field

[0001] The invention relates to the technical field of pipeline anti-corrosion spraying, and in particular to an anti-corrosion spraying device for pneumatic conveying pipelines. Background Art

[0002] The anti-corrosion coating technology for the inner wall of pneumatic conveying pipelines is mainly used to improve the corrosion resistance of pipelines and extend the service life of pipelines. The anti-corrosion coating processing methods are mainly divided into two types: on-site spraying and factory spraying. In the prior art, when anti-corrosion spraying is performed on the inner wall of the pipeline, the spraying device inside the pipeline is generally transported intermittently at a fixed distance by a mobile robot or a conveying mechanism. The spraying device generally uses a spray gun that rotates at a constant speed to continuously and evenly spray the atomized paint on the inner wall of the pipeline.

[0003] However, the traditional operation method of anti-corrosion spraying on the inner wall of the pipeline has the following defects: 1. The traditional spraying method is generally unable to synchronously position multiple pipelines and synchronously spray the multiple pipelines after positioning, which may cause spraying errors when the spraying mechanism sprays multiple pipelines separately in sequence, resulting in inconsistent spraying thickness and effect between the pipelines, further resulting in differences in anti-corrosion, wear resistance and other properties between the pipelines, which may affect the overall stability of the pneumatic conveying system; 2. The traditional spraying method is to spray the inner wall of the pipeline in sections by a spraying device. Generally, the spraying device needs to move a specific distance and then stop until the spray gun evenly sprays the paint on the inner wall of the section of the pipeline before moving. During spraying, the spray gun needs to rotate multiple times at a uniform speed in one direction to ensure that the uniformity and thickness of the paint on the inner wall of the pipeline meet the requirements. However, the operation steps of this spraying method are relatively cumbersome. At the same time, it takes a long time for the spraying device to move intermittently and the spray gun to rotate multiple times for uniform spraying, resulting in low efficiency of the overall spraying operation.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1 A pneumatic conveying pipeline anti-corrosion spraying equipment includes an operating table 1, a conveying wheel 2, a limiting mechanism 3, a spraying mechanism 4 and a clamping mechanism 5. The operating table 1 has multiple groups of conveying wheels 2 that rotate evenly inside to convey the pipeline. The front end of the operating table 1 is fixedly provided with a limiting mechanism 3 for positioning the pipeline. The rear end of the operating table 1 is fixedly provided with a spraying mechanism 4 for spraying the inner wall of the pipeline. The surface of the spraying mechanism 4 is evenly fixedly provided with a clamping mechanism 5 for clamping the pipeline.

[0030] See also Figure 1 and Figure 2The limit mechanism 3 includes a limit frame 31, a limit shaft 32, a through hole 33, a locking assembly 34 and a limit assembly 35; the limit frame 31 is fixedly arranged at the front end of the operating table 1, and the limit shafts 32 are symmetrically fixedly arranged on the left and right sides of the limit frame 31, and the through holes 33 located on the lower side of the limit shaft 32 are symmetrically opened on the left and right sides of the limit frame 31, and the locking assembly 34 is slidably arranged on the outer side of the limit frame 31, and a plurality of limit assemblies 35 cooperating with the locking assembly 34 are elastically slidably arranged on the limit frame 31.

[0031] See also Figure 1 and Figure 2 The locking assembly 34 includes a linkage plate 341, a linkage rod 342, a limiting slide groove 343 and a threaded pin 344; the linkage plates 341 are symmetrically slidably arranged on the left and right sides of the limiting frame 31, and the upper ends of the left and right two linkage plates 341 are fixedly connected by two symmetrically arranged linkage rods 342, and the surface of the linkage plate 341 is provided with a limiting slide groove 343 that slides with the limiting shaft 32, and the lower end of the linkage plate 341 is threadedly provided with a threaded pin 344 that cooperates with the through hole 33.

[0032] See also Figure 1 and Figure 3 The limiting assembly 35 includes a driven block 351, a limiting plate 352 and a rotating wheel 353; a plurality of evenly arranged driven blocks 351 are slidably connected between the connecting rods 342, and a limiting plate 352 elastically slidingly matched with the inner side of the limiting frame 31 is fixedly provided on the lower side of the driven block 351 through two rods, and a rotating wheel 353 is rotatably provided on the front side of the limiting plate 352 through a support.

[0033] When multiple pipes are to be positioned synchronously on the operating table 1, first, all the driven blocks 351 and the limit plate 352 are driven to move upward as a whole through the linkage plate 341, and then the pipes are placed from the front end of the operating table 1 into the operating table 1. When the rotating wheel 353 is located above the right end of the pipe, the linkage plate 341 is released. Under the rebound force of the spring corresponding to the limit plate 352 and the action of gravity, the rotating wheel 353 moves downward to contact the surface of the pipe. The rotating wheel 353 and the conveying wheel 2 in the operating table 1 can facilitate the loading of the pipes while reducing the degree of wear on the surface of the pipes. When multiple pipes are completely placed in the operating table 1 and the rear ends of the pipes are clamped by the clamping mechanism 5, When clamped and fixed, the rotating wheel 353 is separated from the pipe. At this time, under the corresponding rebound force of the limit plate 352 and the action of gravity, all the limit plates 352 move downward again and stably clamp the front end of the corresponding pipe in the operating table 1. Finally, all the limit plates 352 are completely locked by screwing the inner end of the threaded pin 344 into the through hole 33, thereby completing the synchronous clamping and positioning of all pipes. The above-mentioned synchronous and stable limiting method simplifies the overall positioning process while ensuring the consistency of the positioning of multiple pipes, thereby providing working conditions for the subsequent spraying mechanism 4 to synchronously spray multiple pipes under the same positioning conditions.

[0034] See also Figure 1 The spraying mechanism 4 includes a positioning frame 41, a driving assembly 42, a feeding assembly 43, a linkage assembly 44 and a spraying assembly 45; the positioning frame 41 is fixedly provided at the rear end of the operating table 1, the driving assembly 42 is fixedly provided on the right side of the positioning frame 41, and multiple groups of feeding assemblies 43 that cooperate with the driving assembly 42 for transmission are evenly arranged in the positioning frame 41, the lower side of the feeding assembly 43 is cooperated with the linkage assembly 44, and the front end of the feeding assembly 43 is fixedly provided with a spraying assembly 45 that cooperates with the linkage assembly 44.

The driving motor 421 is fixedly provided on the right side of the positioning frame 41 through a plate, and the driving wheel 422 is fixedly provided on the driving end of the driving motor 421 .

[0036] See also Figure 1 , Figure 4 and Figure 5 The feeding assembly 43 includes a threaded sleeve 431, a linkage wheel 432, a transmission wheel 433, a threaded rod 434 and a rotating seat 435. The threaded sleeve 431 is rotatably installed in the positioning frame 41. The rear side of the threaded sleeve 431 is fixedly provided with a linkage wheel 432 that cooperates with the driving wheel 422 through a belt and a transmission wheel 433 that cooperates with the linkage assembly 44 in sequence. The threaded sleeve 431 is internally threadedly connected with a threaded rod 434, and a rotating seat 435 is fixedly provided at the front end of the threaded rod 434.

[0037] When it is necessary to drive multiple groups of spray components 45 to feed synchronously and at a uniform speed, start the driving motor 421 to rotate the driving wheel 422. The driving wheel 422 can synchronously drive all the linked wheels 432 and the threaded sleeve 431 on the positioning frame 41 to rotate synchronously through belt transmission, thereby driving the corresponding multiple groups of spray components 45 to feed synchronously and at a uniform speed through the threaded cooperation between the threaded sleeve 431 and the threaded rod 434. The above-mentioned driving method can ensure that different spray components 45 can be fed in a coordinated manner so that spraying operations can be performed on multiple pipelines synchronously, which simplifies the spraying operation process and greatly improves the efficiency of the spraying operation.

[0038] See also Figure 1 , Figure 4 and Figure 5 The linkage assembly 44 includes a driving sleeve 441, a driven wheel 442, a driven slide rod 443, a stabilizing wheel 444 and a first bevel gear 445; a driving sleeve 441 located below the threaded sleeve 431 is rotatably provided on the positioning frame 41, a driven wheel 442 matched with the transmission wheel 433 through a belt is fixedly provided at the rear end of the driving sleeve 441, a rectangular columnar driven slide rod 443 is slidably provided in the driving sleeve 441, a stabilizing wheel 444 rotatably matched with the lower end of the rotating seat 435 is fixedly provided at the front end of the driven slide rod 443, and a first bevel gear 445 is fixedly provided on the front surface of the stabilizing wheel 444 through a rod.

[0039] See also Figure 1 and Figure 4 The spray assembly 45 includes a spray frame 451, a worm 452, a second bevel gear 453, a linked turbine 454, a driven cam 455, a crankshaft 456, an atomizer box 457 and a spray tube 458; the front surface of the rotating seat 435 is fixedly provided with a spray frame 451, and the left and right sides of the rear surface of the spray frame 451 are symmetrically fixedly provided with sliding rods that slide with the positioning frame 41.

[0040] When spraying is to be performed synchronously on multiple pipelines under the same positioning condition, the driving motor 421 is used to synchronously drive all the linked wheels 432 and the threaded sleeve 431 on the positioning frame 41 to rotate, and the threaded sleeve 431 then drives the corresponding threaded rod 434 to drive the spraying frame 451 in each pipeline to feed synchronously and uniformly. At the same time, the transmission wheel 433 on each threaded sleeve 431 drives the corresponding driven wheel 442 and the driving sleeve 441 to rotate synchronously through the belt drive, and the driving sleeve 441 then drives the driven sliding rod 443, so that the driven sliding rod 443 drives the first bevel gear 445 to rotate while synchronously moving with the threaded rod 434, and the first bevel gear 445 drives the second bevel gear 453 and the worm 45 2 rotates, the worm 452 drives the linked turbine 454 to rotate, and the linked turbine 454 drives the driven cam 455 to swing back and forth at a fixed angle left and right through the rod, so that the atomization box 457 drives the evenly distributed spraying tubes 458 to swing back and forth evenly to spray the atomized paint onto the inner wall of the pipeline, thereby ensuring that the inner wall of the pipeline can be evenly sprayed without dead angles. Compared with the single-tube spraying method, the above-mentioned spraying method can not only increase the spraying area of ​​the inner wall of the pipeline per unit time and improve the overall spraying efficiency, but also enable all the spraying tubes 458 to spray in a mode of continuous synchronous uniform feeding and synchronous deflection, thereby achieving uniform and unified spraying of all pipelines.

[0041] Driven by the driving motor 421, each spray rack 451 is fed synchronously, so that under the same positioning conditions, the atomization box 457 in each pipeline and the spray tube 458 on its surface can perform spraying operations synchronously, thereby greatly improving the consistency of the spraying effect between the pipelines and the stability of the overall spraying effect, thereby improving the overall stability of the pneumatic conveying system.

[0042] See also Figure 1 The clamping mechanism 5 includes a clamping frame 51, a transmission assembly 52, a clamping assembly 53 and a transmission rod 54; a plurality of groups of clamping frames 51 are evenly and symmetrically fixedly arranged on the upper and lower sides of the positioning frame 41, and a transmission assembly 52 is arranged on the surface of the clamping frame 51. A clamping assembly 53 is rotatably arranged on one end of the clamping frame 51 away from the positioning frame 41, and the clamping assembly 53 and the transmission assembly 52 are matched with each other through a transmission rod 54.

[0043] See also Figure 1 and Figure 6 The transmission assembly 52 includes a transmission platform 521 and a stabilizing slide 522; the front side of the clamping frame 51 is provided with a transmission platform 521 rotatably connected to the lower end of the transmission rod 54, and the rear surface of the transmission platform 521 is fixedly provided with a stabilizing slide 522 elastically slidingly matched with the clamping frame 51.

[0044] See also Figure 1 and Figure 6The clamping assembly 53 includes a rotating frame 531, a clamping plate 532 and a rubber pad 533; the end of the clamping frame 51 away from the positioning frame 41 is rotatably provided with a rotating frame 531 rotatably connected to the upper end of the transmission rod 54, the front end of the rotating frame 531 is fixedly provided with a clamping plate 532, and the inner surface of the clamping plate 532 is fixedly provided with a rubber pad 533.

[0045] When the rear end of the pipe pushes the transmission platform 521 backward and presses it completely, the limit plate 352 is clamped on the outer ring surface of the front end of the pipe. At the same time, the transmission platform 521 drives the rotating frame 531 to rotate inward through the transmission rod 54, so that the rubber pad 533 on the inner surface of the clamping plate 532 presses the outer ring surface of the rear end of the pipe, thereby clamping and positioning the pipe in the operating table 1. The rubber pad 533 ensures stable clamping of the pipe and prevents the pipe from loosening during the spraying operation, thereby ensuring the stability of the spraying operation and the spraying effect.

[0046] When the limit of the linkage plate 341 is released by rotating the threaded pin 344, and then the lock of the limit plate 352 on the front end of the pipe is released, at this time, driven by the rebound force of the spring corresponding to the stable slide 522, the transmission platform 521 moves forward and drives the rotating frame 531 to rotate outward through the transmission rod 54 to release the rear end of the pipe. At the same time, the pipe moves forward a distance under the push of the transmission platform 521. When the rotating wheel 353 is located above the front end of the pipe, the linkage plate 341 is released, the rotating wheel 353 moves down to contact the outer annular surface of the pipe, and then the pipe is continued to move forward for unloading through manual or existing traction equipment. The above unloading method is convenient and fast, and multiple pipes can be unlocked simultaneously, which simplifies the operation process and improves the overall efficiency of the spraying operation.
