Before each paint liquid filling, the hose 132 is taken down, the upper cover 123 is opened, the paint liquid and the diluent which are mixed in proportion are added into the paint spraying tank 121, the upper cover 123 is covered, then nitrogen (with the pressure of about 0.6 MPa) is added into the paint spraying tank 121 through the air adding nozzle 129 through the nitrogen tank, the paint spraying tank 121 is placed in the middle of the upper part of the shell 8 after air adding, and the magnet 1211 at the lower end of the paint spraying tank 121 is attracted to the middle of the lower part of the shell 8, so that in use, the paint spraying tank 121 cannot shake, the stability in spraying is guaranteed, and finally the liquid outlet end of the electromagnetic valve 122 and the right side of the paint outlet pipe 130 can be put into use after being connected in a sleeved mode through the hose 132. Before this novel use, the automobile body is put inside equipment or pipeline, turn on switch S1, after S2, light H gets electric and gives out light and be this novel whole illumination, camera SX in real time with the equipment of shooting, and video signal shows through display A' S display screen in the pipeline, operating personnel reaches outside the equipment outside the pipeline, can be according to the movement track (seesaw or side-to-side movement) of the video operation dolly body 11 of display screen, and then to the pipeline in or the operation of spraying paint in the equipment.

As shown in fig. 1 and 2, if an operator needs to control the vehicle body 11 to move forward outside the equipment and the pipeline, the operating handles of the two power switches SK1 and SK2 are respectively shifted to the front side, so that the two ends 1 and 2 of the power input of the two power switches SK1 and SK2 are respectively communicated with the first power output end 3 and 4, since the first power output end 3 and 4 of the power switches SK1 and SK2 are respectively connected with the positive and negative pole power input ends of the motor speed reducing mechanisms M1 and M2 of the left and right wheels at the front side end and the rear side end of the vehicle body 11 through wires, the motor speed reducing mechanisms M1 and M2 of the left and right wheels at the front side end and the rear side end of the vehicle body 11 are electrically operated to rotate counterclockwise, and under the action of the motor speed reducing mechanisms M1 and M2 of the left and right wheels at the front side end and the rear side end of the vehicle body 11, the left and right wheels and rear side end of the vehicle body 10 move counterclockwise, and further, the effect of controlling the trolley body 11 to move forwards is achieved, after the power switches SK1 and SK2 are turned off, the motor speed reducing mechanisms M1 and M2 of the left wheel and the right wheel at the front side end and the rear side end of the trolley body 11 lose power at the same time, and the trolley body does not move forwards any more. If an operator needs to control the backward movement of the trolley body 1 outside the equipment and the pipeline, the operating handles of the two power switches SK1 and SK2 are respectively shifted towards the backward side, then, the two

ends

1 and 2 of the power input of the two power switches SK1 and SK2 are respectively communicated with the two ends 5 and 6 of the second power output, because the two ends 5 and 6 of the second power output of the power switches SK1 and SK2 are respectively connected with the negative and positive pole power input ends of the motor speed reducing mechanisms M1 and M2 of the left and right wheels of the front side end and the rear side end of the trolley body 11 through conducting wires, the motor speed reducing mechanisms M1 and M2 of the left and right wheels of the front side end and the rear side end of the trolley body 11 are simultaneously powered to work clockwise, and under the action of the motor speed reducing mechanisms M1 and M2 of the left and right wheels of the front side end and the rear side end of the trolley body 11, the left and right wheels of the front side end, and further, the effect of controlling the backward movement of the trolley body 11 is achieved, after the power switches SK1 and SK2 are turned off, the motors M1 and M2 of the left wheel and the right wheel at the front side end and the rear side end of the trolley body 11 lose power at the same time, and the trolley body does not move backward any more.

As shown in fig. 1 and 2, if the operator needs to control the vehicle body 11 to make a left turn on the outer side of the equipment and the pipeline, the operating handle of the power switch SK1 is turned off, so that the two wheels 10 at the rear end of the vehicle body 11 continue to move due to the power switch SK2 being turned on, and the vehicle body 11 makes a left turn. If an operator needs to control the vehicle body 1 to go forward and turn right on the outer side of the equipment and the pipeline, the operating handle of the power switch SK2 is closed, so that the two wheels 10 at the front side end of the trolley body 11 continue to move due to the fact that the power switch SK1 is opened, and the trolley body can turn right. If an operator needs to control the vehicle body 1 to turn left after going outside the equipment and the pipeline, the operating handle of the power switch SK2 is closed, so that the two wheels 10 at the front side end of the trolley body 11 continue to move due to the fact that the power switch SK1 is opened, and the trolley body 11 turns left. If an operator needs to control the vehicle body 1 to turn right after going outside the equipment and the pipeline, the operating handle of the power switch SK1 is closed, so that the two wheels 10 at the rear end of the trolley body 11 continue to move due to the fact that the power switch SK2 is opened, and the trolley body turns right.

As shown in fig. 1 and 2, during the novel spraying operation, when the spray head 128 of the spray mechanism 12 is required to spray paint, the power switch S4 is turned on, so the electromagnetic valve DC is powered on to work, and the paint liquid in the paint can 121 is acted on the equipment to be sprayed through the mist spraying of the spray nozzle 128 from the inner ring middle parts of the paint inlet pipe 131, the paint outlet pipe 130, the two bearings 1251, the connecting pipe 1281 and the lower sleeve 1282 under the action of the filled nitrogen pressure. During this novel spraying operation, when operating personnel need the rotatory 360 degrees of shower nozzle 128 of mechanism 12 that sprays paint to spray paint (for example inside the spraying pipeline), switch S4 is opened simultaneously, S3, then, motor gear reducer M and solenoid valve DC all get electric work, when the vaporific lacquer liquid of shower nozzle blowout, motor gear reducer M can drive reduction gear 126 (speed reduction increase moment of torsion) clockwise through driving gear 127, and then, reduction gear 126 drives connecting pipe 1281 and lower casing 1282 of mechanism 12 that sprays paint, shower nozzle 128 rotates, just so can realize that the shower nozzle can also incessant 360 degrees rotations when spraying paint, it is more effective inside to the spraying pipeline very much. In order to guarantee the spraying effect, the novel control is moved to the end point of the paint spraying operation point in the actual operation, then the vehicle body 11 retreats for spraying operation, and the influence of the rolling of the wheels on the previously sprayed paint liquid in the movement of the trolley body 11 is prevented. In the 360-degree rotation of the spray head, the right part of the connecting pipe 1281 rotates along the inner left bearing inner ring of the sleeve 1252, and the paint outlet pipe 130 is positioned in the inner right bearing inner ring of the sleeve 1252, so that the rotation of the paint outlet pipe 130 cannot be caused when the connecting pipe 1281, the spray head 128 and the like rotate, and the normal operation of spraying is ensured. When the power switches S3 and S4 are turned off, the solenoid valve DC (valve element closed) and the motor deceleration device M are both de-energized, and the painting mechanism 12 stops the painting operation. When the spray-painting operation is required to change the position of the spray nozzle at a fixed position of the equipment, an operator turns on the power switch S3, and turns off the power switch S3 after the motor reduction equipment M drives the spray nozzle 128 to rotate to the required position through the driving gear 127 and the large gear 126.

As shown in fig. 1 and 2, when the radius of the pipeline is reduced or increased during operation, in order to ensure good spraying effect in the pipelines with different inner diameters, namely, the distance between the spray head 128 and the pipeline needs to be changed, so that the spray radius is enlarged or reduced, the spray head can be more properly spaced with the spraying surface, and further, when the spraying effect is more uniform, an operator can meet the requirement by adjusting the distance between the lower sleeve 1282 and the connecting pipe 1281 before use. When the length between the lower casing 1282 and the left part of the connecting pipe 1281 needs to be lengthened and the subsequent painting radius needs to be enlarged, the operator rotates the lower casing 1282 downwards along the connecting pipe 1281, so that the length between the lower casing 1282 and the connecting pipe 1281 is lengthened. When the length between the lower sleeve 1282 and the connecting pipe 1281 needs to be shortened and the subsequent paint spraying radius is reduced, the operator rotates the lower sleeve 1282 upwards along the connecting pipe 1281, so that the length between the lower sleeve 1282 and the connecting pipe 1281 is shortened. In practical situations, a lock nut may be disposed between the lower sleeve 1282 and the connecting tube 1281, and after the lower sleeve 1282 is adjusted in place, the lock nut is screwed to tightly contact the lower end of the lower sleeve 1282 with the upper end of the lower sleeve 1282, so as to prevent the lower sleeve 1282 from being displaced under a rotational force during subsequent operations, which may result in a decrease or an increase in the paint spraying radius of the nozzle 128. This novel finish spraying paint once or many times after, in order to guarantee next use, can add washing liquid and compressed nitrogen gas in the jar that sprays paint, can effectively wash the route that paint flows through when the operation last time after the washing liquid blowout, guaranteed subsequent effect of spraying paint. It should be noted that, this novel be used for in the pipeline during 360 degrees rotatory spraying, generally be used for fixed internal diameter pipeline to use, when the pipeline that needs to internal diameter grow or diminish in 360 degrees rotatory spraying, need increase and decrease between the motor reduction gears of wheel and the shell lower extreme and support packing ring etc. and then change the whole height of automobile body, can be close unanimously with in the pipeline, circumferencial direction optional position distance when guaranteeing the shower nozzle rotatory, reach good spraying effect. If 360 degree rotational painting is not required, then the height of the vehicle body need not be changed. This novel supporting air compressor machine that does not need uses, and is small, account for the space few, combines the automatic advantage of spraying paint of current manual filling, and the jar body of the mechanism that sprays paint can relapse the filling lacquer liquid and use, and the during operation can carry out 360 degrees no dead angles spraying operations in equipment and pipeline automatically under relevant mechanism combined action to the operation personnel have brought the facility.
