Adopt technique scheme, in the process that dolly moves forward, the straight tube that can drive on it moves forward, and makes paint nozzle extend into guardrail pipe depths, and the guardrail inside pipe wall is sprayed.
In the utility model embodiment, dolly the place ahead also is provided with the support that supports hollow straight tube.
In the utility model embodiment, also comprise a track, described dolly bottom has wheel that is positioned on the track and the drive motors that drives wheel.Press linear running by the rail-guided dolly that can guarantee.
In the utility model embodiment, dolly is provided with the gauge tap of high-pressure airless coating applicators.
The utility model paint spraying machine for inner wall of steel pipe has adopted and established hollow straight tube on dolly, be connected with in the hollow straight tube and be coated with material conveying tube, be coated with material conveying tube one end and be communicated to the high-pressure airless coating applicators, the other end is provided with paint nozzle, slide the drive straight tube in orbit by dolly and move, shower nozzle can be extend in the guardrail pipe its inwall is sprayed.During the utility model paint spraying machine for inner wall of steel pipe sprayed coating, be not splashed to the coating in the environment, save coating, can not destroy environment, energy-saving and emission-reduction.Easy and simple to handle, the spraying with low cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
The structural representation of Fig. 1 the utility model paint spraying machine for inner wall of steel pipe.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with Fig. 1,2 and embodiment of the present utility model describe in further detail:
Fig. 1 shows the embodiment schematic diagram of the utility model paint spraying machine for inner wall of steel pipe.As shown in Figure 1, be provided with dolly 100 on track 200, dolly 100 bottoms have wheel 101, and dolly 100 can slide on track 200.Be provided with drive motors 106 in the dolly 100, drive motors 106 is connected to wheel 101 by gear, start drive motors 106 and can drive wheel 101 rotations, and then drive dolly 100 slides on track 200.Four elongated straight tubes 400 are fixed on the dolly 100, and stretch out outside the dolly 100, stretch to the place ahead, the front end of every straight tube 400 is equipped with a paint nozzle 802, straight tube 400 is a hollow, in be provided with one carry coating be coated with material conveying tube 800, be coated with material conveying tube 800 1 ends and be communicated with, other end connection paint nozzle 802 with high-pressure airless coating applicators 700.Be coated with material conveying tube 800 after high-pressure airless coating applicators 700 is opened, the coating of 700 li of high-pressure airless coating applicators can be sent to paint nozzle 802 by being coated with material conveying tube 800, coating is ejected on the inwall of guardrail pipe 500 from the spray orifice on the paint nozzle 802.Straight tube 400 outer walls are provided with the support 404 that three groups of intersections are hinged, be respectively equipped with wheel 405 on one end of three pack supports 404, support 404 can be regulated intersecting angle by hinged part, makes straight tube 400 can stretch into the guardrail pipe of different bores and guarantee that shower nozzle 802 is on the steel pipe axis not collide with inwall.In the time of in paint spraying machine for inner wall of steel pipe of the present utility model stretches into guardrail pipe 500, the intersecting angle of adjusting support 404 can be attached on guardrail pipe 500 inwalls wheel 405 and slides.The utility model paint spraying machine for inner wall of steel pipe is provided with wheel and slides at guardrail pipe 500 inwalls on straight tube 400 outer walls, the straight tube 400 that stretches into guardrail pipe 500 can be extend in the guardrail pipe 500 Anywhere, also give 400 1 uniform support forces of straight tube, make in guardrail pipe 500 mobile very reliable.Can be provided with a gauge tap on the dolly 100 of paint spraying machine for inner wall of steel pipe of the present utility model, the coating that it can control hollow straight tube 400 transmits, when gauge tap is opened, coating can be passed through straight tube 400 from 700 li of high-pressure airless coating applicators and transmit, and be sprayed on guardrail pipe 500 inwalls by paint nozzle 802.
Because guardrail pipe 500 is very long, so spray paint conveniently in order to put in guardrail pipe 500 the insides, the length of straight tube 400 can not be lower than the length of guardrail pipe 500, its strong point is positioned on dolly 100 and the wheel 405, in order to reach better conveying coating and spraying effect, also be provided with a support 600 that supports at straight tube 400 in dolly 100 the place aheads, the holder power of making progress for 400 1 of straight tubes, and the original strong point can be shifted.
Paint spraying machine for inner wall of steel pipe of the present utility model in use, earlier the paint nozzle of straight tube is aimed at guardrail Guan Yiduan, adjust the intersecting angle of the intersection frame of straight tube outside, when making it stretch into the guardrail pipe, wheel can be attached on the guardrail inside pipe wall and slide, and straight tube is stretched in the guardrail pipe, opens the gauge tap on the dolly, coating in the high-pressure airless coating applicators is transported to the paint nozzle place by the material conveying tube that is coated with in the straight tube, sprays on the guardrail inside pipe wall by spray orifice.Start the drive motors on the dolly, drive wheel and rotate, dolly is slided in orbit, when dolly slides straight tube is pushed away in the guardrail pipe, wheel just slides on the guardrail inside pipe wall, and paint nozzle is sliding along with dolly just, in the guardrail pipe, stretch on one side, on one side the guardrail inside pipe wall is sprayed.
The utility model paint spraying machine for inner wall of steel pipe is provided with four hollow straight tubes on a dolly, can spray four guardrail pipes simultaneously.The utility model can also be provided with more hollow straight tube according to user's needs on dolly, be provided with one in the every hollow straight tube and be coated with material conveying tube.Adopt this scheme, not only accelerated the operation process, also saved the time, efficient is high and saved coating.
