Described drive unit is by being arranged at drive motors, double reduction gear group on the base, going out cable reel and the inlet wire reel is formed, wherein the double reduction gear group is connected with drive motors, go out cable reel and inlet wire reel and be located at double reduction gear group both sides respectively, go out the steel wire rope that twines on cable reel and the inlet wire reel and all be connected with the spray car.
Described travel mechanism comprises the carriage motor of being located at movable base top and is located at the universal wheel and the driving wheel of movable base below, and the drive sprocket on the carriage motor is by being connected by movable sprocket on chain gear transmission band and the driving wheel; The speed that carriage motor is regulated universal wheel by frequency converter satisfying different speed needs, thereby is controlled the translational speed of whole traversing carriage.
Described arch truss is assembled fast by universal rod body, for convenience detach, the transportation and the assembling.
The transmission mechanism of described spray car is connected to form successively by triangular driving band, decelerator and drive plate, and described spray tramcar motor is connected with triangular driving band one end, and described crank and rocker mechanism is connected with drive plate.
Described carrier pipe is sediment transport pipe or transmission pipe, and is corresponding with the sand-blasting gun or the painting nozzle that connect on the described spray gun holder.
Described control device is made up of frequency converter, travel switch and Programmable Logic Controller (PLC), and entire work process is controlled, and realizes the whole-course automation of rust cleaning or spraying.
Compared with prior art, the present invention has following beneficial effect with respect to prior art:
(1) comparatively abominable at working environment, the dusty actual conditions of dust, the present invention adopts PLC that entire work process is controlled, and realizes whole-course automation, has improved operating efficiency greatly.
(2) the present invention's arch steel plate rust cleaning of being used for heavy construction has reduced the difficulty of its work when spraying paint greatly, and the guarantee that strengthens working security simultaneously reduces unnecessary damage, has also improved the assurance of construction quality greatly.
