s2: the control system controls the first sliding block to ascend to the top position, when the first sliding block is at the top position, the polishing assembly is started, the surface of the pressure container is polished by using the polishing end, and simultaneously, the control system controls the second sliding block to drive the polishing assembly to move circumferentially around the pressure container and finish polishing of the pressure container;

s3: and after polishing for at least one circle, the control system controls the first sliding block to descend and continues polishing until polishing is finished.

In a specific embodiment of the invention: in step S2, the main driver driving base is kept in a horizontal state, at this time, the sub driver drives each polishing brush to rotate and polish the pressure vessel, and in the polishing process, the sub driver drives each reel to move respectively, so that the cord alternately moves in both a relaxed state and a tightened state;

when the thread rope is loosened, the pressure of the thread rope is lost by the adjusting wheel on the piston rod below, the auxiliary agent in the adjusting body is filled into the piston body corresponding to the piston rod, and meanwhile, the auxiliary agent in the rest of the piston bodies is supplemented into the adjusting body, and the piston rods in the rest of the piston bodies move, so that the position of the polishing brush is changed;

when the thread rope is tightened, the adjusting wheel on the piston rod positioned below receives the pressure of the thread rope, presses the auxiliary agent in the corresponding piston body into the adjusting body, and further sends the auxiliary agent into the other piston bodies, and enables the other piston rods to move, so that the positions of the polishing brushes are changed again;

after one round of polishing with the base kept horizontal, the main driver drives the base to keep an inclined state and performs polishing again with the base in the inclined state.

In a specific embodiment of the invention: in the grinding process, if the grinding brush needs the auxiliary agent, the second driver and the return spring control the second movable body to move, when the second movable body is returned through the return spring, negative pressure is generated in the material discharge cavity, the auxiliary agent in the auxiliary agent source is sent into the screening cavity and enters the material discharge cavity from the first material outlet, and when the second movable body is controlled to move by the second driver, the auxiliary agent in the material discharge cavity is pressed out from the third material outlet by the second movable body and is supplied to the grinding brush;

when the movable end of the adjusting body or the second driver needs the auxiliary agent, the movable end of the second driver moves in the movable cavity, and during movement, negative pressure is generated in the movable cavity, the auxiliary agent is sent into the screening cavity from the auxiliary agent source, granular substances are filtered out through the filter screen, discharged from the second discharge port and enter the movable cavity, and further sent into the adjusting body through the fourth discharge port.

Referring to fig. 3-6, the principles and advantages of the present embodiment are:

firstly, referring to fig. 4, in this embodiment, the grinding brush forms a grinding portion and can be controlled to rotate (which may be a motor) by a sub-driver, and the surface of the pressure vessel is ground by the rotating grinding brush, when the grinding brush rotates, the second slider moves on the second guide rail, and can drive a plurality of grinding brushes to move around the pressure vessel and finish grinding work, and because the surface of the pressure vessel has a certain curvature, the grinding surface of the grinding brush can be adapted to the pressure vessel for manufacturing, as long as the grinding surface of the grinding brush can be in contact with the surface of the pressure vessel when the grinding brush moves;

in this embodiment, the sub-actuator (not shown, but may be a motor) may be controlled by the first controller and the second controller to operate in the first operation mode or the second operation mode, when in the first operation mode, the reel is released, and therefore, the third piston rod and the fourth piston rod lose the pressure of the cord and descend due to gravity, and at this time, the second auxiliary agent in the adjusting body enters the third piston body and the fourth piston body, and at this time, the second auxiliary agent in the first piston body and the second piston body is replenished into the adjusting body, and when the first piston rod and the second piston rod lose the support of the second auxiliary agent in the first piston body or the second piston body, both slide toward the connection part of the piston body and the adjusting body, and at this time, the polishing brush controlled by the first piston rod and the second piston rod moves, and the third piston rod and the fourth piston rod descend due to gravity, therefore, the grinding brushes on the third piston rod and the fourth piston rod also move, so that the grinding coverage can be improved, and meanwhile, impurities between the grinding brushes and the pressure container can be discharged;

in a second running mode, the winding wheel winds up and fast tightens the cord, the third piston rod and the fourth piston rod move upwards under the influence of the cord, the second auxiliary agent in the third piston body and the fourth piston body is pressed into the adjusting body and further pressed into the first piston body and the second piston body, and the first piston rod and the second piston rod move upwards under the action of the second auxiliary agent, so that the position changes again;

in this embodiment, referring to fig. 4, there are 4 polishing brushes in this embodiment, and the polishing brushes on the upper layer are closer in position distance, and the polishing brushes on the lower layer are farther in position distance, so as to reduce the mutual influence of the polishing brushes during moving and dust exhaust, and meanwhile, in order to ensure that the polishing brushes on the upper layer can descend without the support of the second auxiliary agent, the first piston body and the second piston body are arranged in an inclined manner in this embodiment;

the second operation mode of the embodiment can improve the synchronism during winding, ensure that the winding wheel is provided with the wire rope, and ensure that the wire rope can be normally unwound subsequently;

in addition, in order to improve the polishing effect, an additive source (which may be a container for storing a rust remover and polishing particles) is provided in this embodiment, the rust remover and the polishing particles can form a first additive which can be used for assisting polishing to ensure the rust removal and impurity removal effects, and a second additive which does not contain polishing particles can be used for lubricating the movable end of the second actuator and supplementing the required second additive for the adjustment body;

namely: referring to fig. 5-6, when polishing and requiring the assistance of the first auxiliary agent, the first driver controls the first movable body to ascend, and the opening of the filter screen is adjusted to be minimum (the opening of the filter screen refers to the area of the filter screen which can be penetrated by the auxiliary agent), and the second driver controls the second movable body to extrude the return spring, after extrusion, due to the effect of the check valves (which can be replaced by the existing relief valves) at the first discharge port and the third discharge port, the medium in the first movable body can be discharged, so that the discharge cavity tends to be in a vacuum state, at this time, the second driver is removed, the second movable body is reset under the impression of the return spring, and at the same time, negative pressure is formed in the discharge cavity, so that the auxiliary agent in the auxiliary agent source can enter the filter cavity through the first feed port and enter the discharge cavity through the first discharge port, and when the second movable body extrudes the return spring again, the second auxiliary agent is discharged through a third discharge port and is discharged to each polishing brush (the third discharge port can be provided with a material pipe extending to the polishing brush), so that the polishing effect of the polishing brushes is improved;

when a second auxiliary agent is needed, the first movable body can be controlled to descend through the first driver, the opening degree of the filter screen is adjusted to be the maximum, at the moment, the second driver moves in the movable cavity and does not push the second movable body to move, when the movable end of the second driver moves in the movable cavity, negative pressure can be used, so that the second auxiliary agent filtered by the filter screen is discharged into the oil passing channel from the second discharge hole, can dissipate heat and lubricate the movable end of the second driver through the movable cavity, is discharged through the fourth discharge hole and enters the adjusting body, and if the first auxiliary agent needs to be discharged from the adjusting body, the discharge electromagnetic valve can be opened to enable the auxiliary agent to flow back to the gradual source;

in conclusion, in the embodiment, the second auxiliary agent can be provided for the polishing brush to assist polishing during polishing, so that the polishing effect is improved;

secondly, the first auxiliary agent can be used for lubricating and radiating the second driver, and the adjusting body is complemented, namely, the device can be maintained in the process of complementing the auxiliary agent to the adjusting body, so that the aim of killing two birds with one stone is fulfilled;

thirdly, when the auxiliary agent is replaced, the grinding particles in the auxiliary agent can be recovered, the rust remover with the expiration date is discharged, a new rust remover is added, useful resources are recycled, useless resources are completely recovered, and the utilization rate is improved;

fourthly, the polishing brush of the embodiment can move during polishing, so that the polishing area can be increased, partial polishing impurities are discharged, and the polishing effect and efficiency of the whole polishing process are ensured;

fifth, this embodiment can eliminate to some extent the "stress" that produces when polishing, namely: at the in-process of polishing, through control feeding solenoid valve and ejection of compact solenoid valve, the control auxiliary agent flows, and the vibrations that produce when the brush rotation of polishing can be absorbed by the auxiliary agent that flows, and when the auxiliary agent flows, it can reach absorbing effect, when ejection of compact solenoid valve row material, the auxiliary agent volume reduces, at this moment, is equivalent to the spring by the extrusion shrink, and when ejection of compact solenoid valve closed, when the feeding solenoid valve was opened, it was equivalent to the spring and resets to reach absorbing purpose.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
