the inside application device 3 of pipeline sets up in the outside that the pipeline bore 1 one end of rotary device, and the inside application device 3 of pipeline is including stretching into relatively the inside rotation axis 31 of pipeline, rotation axis 31 are cavity, are equipped with a plurality of sparcaps 32 along spiral setting around rotation axis 31, and sparcap 32 all sets up towards the pipeline inner wall, and sparcap 32 all communicates with rotation axis 31, and rotation axis 31 is being connected to the feed pipe, and the spraying of whole inner wall can be accomplished to the rotatory round of rotation axis 31.
In this embodiment, the pipeline bearing and rotating device 1 comprises a platform 11, four roller groups 12 which are distributed in a matrix are fixed on the platform 11, the pipeline can be carried on the four roller groups 12, at least one roller group 12 is provided with a motor for driving the roller to rotate, and the pipeline is driven to rotate in a stepping manner through friction between the roller and the pipeline.
In this embodiment, the linear displacement assembly 22 driving the spraying robot 21 to reciprocate axially along the pipeline adopts a linear screw rod sliding table, which has the advantages of stable operation, high control precision and suitability for spraying.
In one aspect of this embodiment, the rotating shaft 31 may be extended into the pipeline by an external driving device, and then spray-coat the inner wall of the pipeline, for example, a pipeline inner wall spraying method and a spraying robot 21 disclosed in patent No. CN202011277808.6, the disclosed pipeline inner wall spraying method includes the following steps: step 1: horizontally fixing the pipeline, and installing a paint spraying robot outside the pipeline; step 2: a spray head of the paint spraying robot extends into the pipeline and moves in the pipeline along the length direction of the pipeline to uniformly spray the inner wall of the pipeline; and step 3: after the spraying is finished, the spraying robot 21 works to drive the spray head to move out of the interior of the pipeline, the pipeline is disassembled, and the spraying is finished.
In another embodiment of the present invention, a track is laid on the ground, the platform 11 of the pipeline carrying and rotating device 1 and the linear displacement assembly 22 are both mounted on the track through a large-scale second platform, and the driving device drives the pipeline carrying and rotating device 1 and the linear displacement assembly 22 to move integrally toward the rotating shaft 31, so that the pipeline is sleeved outside the rotating shaft 31, and the rotating shaft 31 is opposite to the rotating shaft 31 and extends into the pipeline. The latter solution is advantageous over the former solution in that it does not take up too much space on the ground, the overall length of the device is not as long as the former solution, because the track and the drive as a whole can be buried below ground level and the structure is simpler.
In the present embodiment, a spiral pipe 33 is provided around the rotation shaft 31, the spray head 32 is mounted on the spiral pipe 33, and the cross-sectional shape of the spiral pipe 33 is rectangular for the purpose of more convenient mounting of the spray head 32. Both ends of the spiral pipe 33 are provided with coupling pieces 34 extending in the direction of the rotation shaft 31 for fixing the spiral pipe 33 to the rotation shaft 31. At least one connecting rod 35 is axially distributed along the rotating shaft 31, the connecting rod 35 is sleeved on the rotating shaft 31 and fixed with the inner wall of the spiral pipe 33, and the connecting rod 35 plays a role in reinforcing the spiral pipe 33.
In this embodiment, the two ends of the rotating shaft 31 are provided with auxiliary supporting devices 36, and the auxiliary supporting devices 36 form a sliding fit with the inner wall of the pipeline, and the purpose of the auxiliary supporting devices 36 is to perform centering, ensure that the rotating shaft 31 is coaxial with the pipeline after being inserted into the pipeline, and avoid the phenomenon that the rotating shaft 31 is broken due to too much weight on the rotating shaft 31. Specifically, the auxiliary supporting device 36 includes a herringbone fixing plate 37, and at two bifurcated ends of the fixing plate 37, arc plates 38 are fixed, and the arc plates 38 are attached to the inner wall of the pipeline to form a sliding fit with the pipeline. In addition to the above, pulleys may be mounted at two bifurcated ends of the fixing plate 37 to be slidably engaged with the inner wall of the pipe.
The ends of the arc-shaped plate 38 and the fixed plate 37 may be fixed as described above, but this entails that the length of the fixed plate 37 must be adapted to the fixed diameter pipe, and the arc-shaped plate 38 will also mark against the inner wall of the pipe during the extension of the rotation shaft 31 into the pipe. Therefore, in this embodiment, referring to fig. 5, it is more preferable that the arc plate 38 is telescopic relative to the end of the fixing plate 37, so that before extending into the pipeline again, the arc plate 38 is in a contracted state, and after completely extending into the pipeline, it extends out of the fixing plate 37 and abuts against the inner wall of the pipeline. Two end sides of the fixing plate 37 are provided with linear telescopic mechanisms 39 for driving the arc wire plate, and the linear telescopic mechanisms 39 can adopt cylinders, electric cylinders and the like.
The extension and retraction direction of the linear extension and retraction mechanism 39 should be the same as the radial direction of the pipeline, so that the two arc plates 38 cooperate together to perform a centering function, and ensure that the rotating shaft 31 is coaxial with the pipeline, thereby ensuring uniform spraying.
Meanwhile, it should be noted that the spraying heads 32 installed on the spiral pipes 33 are perpendicular to the inner wall of the pipeline, so as to spray on the inner wall, but the spraying heads 32 at both ends of the spiral pipes 33 are different and are inclined towards both ends of the pipeline, because the auxiliary supporting devices 36 are provided at the positions of both ends of the pipeline to support the rotating shaft 31, and the positions of both ends of the spiral pipes 33 cannot be installed with the spraying heads 32 because of the existence of the auxiliary supporting devices 36, so that the spraying heads 32 at both ends of the spiral pipes 33 need to be inclined towards both ends of the pipeline to spray on the inner wall at the position close to the port of the pipeline.
The invention relates to a pipeline internal and external coating device, which comprises the following working procedures:
the method comprises the following steps: hoisting the pipeline to the pipeline bearing rotating device 1 through equipment;
step two: the spraying robot 21 performs reciprocating motion once along the axial direction of the pipeline to spray the outer wall;
step three: the pipeline bearing and rotating device 1 drives the pipeline to rotate for a certain angle, and the spraying robot 21 reciprocates once along the axial direction of the pipeline to spray the outer wall again;
step four: repeating the second step and the third step until the spraying of the whole outer wall is finished;
step five: inside rotation axis 31 stretched into the pipeline, the auxiliary stay 36 at rotation axis 31 both ends was started, drive arc 38 by sharp telescopic machanism 39 top at the pipeline inner wall, then rotation axis 31 rotatory round, the rotatory spraying that begins in addition to other in the spray head 32 of both ends position on the spiral pipe 33 in the time, drive arc 38 withdrawal by sharp telescopic machanism 39 at last, rotatory round again, the spray head 32 of both ends position on the spiral pipe 33 sprays the inner wall to closing on pipeline port position, so accomplish the spraying of whole inner wall.
