(54) DEVICE FOR CLEANING AND COLORING THE SHIP

 one ,

This invention relates to shipbuilding, in particular, to devices for cleaning and painting the hull of a ship.

A device for cleaning 1: 1 and painting the hull of the vessel, comprising a self-propelled telescopic mast trolley, on which is located a platform with a cleaning working head and a power cylinder, and the following IQ system 1.

However, coating the hulls of large vessels requires an increase in the size of the device, which makes it difficult to use it at the docks. When switching to coating from one surface area to another, the device needs to be reconfigured, as a result of which there is no continuity of the coating process, which reduces the performance of the device. During operation of the device, it is difficult to automatically control the movement of the trolley.

The purpose of the invention is to increase the performance of the device when processing surfaces of complex curvature .30

For this, the device is equipped with a modular hydraulic cylinder located on. guides made on the platform, the power and torque hydraulic cylinders having a common stem, while the working head contains two independently suspended frames that can be rotated relative to each other in mutually perpendicular planes.

In addition, the cleaning work head can be equipped with ball bearings.

FIG. 1 shows the proposed device, a general view; Fig 2 cleared working head; in fig. 3-device hydraulic circuit.

The device contains a self-propelled trolley 1 with a telescopic mast 2, at the end of which a platform 3 is installed with a feed unit consisting of a power two-rod hydraulic cylinder 4 and a torque hydraulic cylinder 5, interconnected by a common rod 6 passing through the dispute 7 with guides 8 . At the end of the rod 6 using the axis. 9 is fixed to the carrying frame 10 of the cleaning working head.

The rotation of the carrier frame 10 relative to the axis 9 in the vertical plane is. ti. limited by a stop 11. To the carrier frame 10, they are mounted with rioMo by finger joints 12, 13 two feed frames 14, 15, Two supporting frames 16 with ball bearings 17 and paint sprays 18 are illuminated with each finger by means of finger joints. The attachment of the nozzles 18 to the support frames 16 ensures a constant distance between the surface and the nozzles, as well as the perpendicularity of the plumes to the surface. The spray gun 19 is attached to the support frame 10 and is used as a supplement when painting concave surfaces. To ensure smooth rotation of the support frames 16, springs 20 are used. The feed frames 14, 15 m rotate relative to the axis at an angle of 25 A, support X, X and Xjj X, frames 16, relative to the OS and OU axes at an angle Y. The device is equipped with a hydraulic a system consisting of a tracking system for controlling the direction of movement of the carriage and for orienting the working body for painting (cleaning) relative to the surface to be treated and the telescopic mast extension control system and feed unit. The hydraulic follow-up system consists of a control hydraulic cylinder 21, in the piston rod of which there is a follower spool 22, a power cylinder 23 of the wheel rotation and a two-positioned distributor 24, as well as adjustable throttles 25 and 26, due to which the oil consumption changes turning the wheels in the cavity of the control cylinder 21 and the power hydraulic cylinder 23, which allows to coordinate the movement of the pistons of the hydraulic cylinders 21 and 23. A signal about the change of the curvature of the surface is transmitted from the spool 22 and from it to the guide of logs 23 wheels turning. The hydraulic control system of telescopic mast extension and feed unit consists of telescopic mast 2, torque cylinder 5, power cylinder 4 and three three-position distributions 27-29. The device works as follows. The self-propelled trolley 1 drives up to the hull of the ship 30 and after that the switching on of the distributor 27 makes the supply and clamping of the working body power cylinder 4 for cleaning (cleaning) the hull to the hull. - V y: The feed unit serves to clamp the working body to the surface to be treated, - as well as to rotate the working body on. relative to the axis of the hydraulic cylinder rod 4. Rotation of the working body for painting (cleaning) is necessary during the movement of the self-propelled trolley along the hull in the opposite direction when moving from one surface to another (painting) the surface. The working body is painted (cleaned) by the piston of the power cylinder 4, and the rotation by the torque cylinder 5, the KOTOpotO piston is rigidly connected to the rod of the power cylinder 4. The momentary cylinder 5 moves progressively along the direction of the 8 of the power cylinder of the hydraulic cylinder 4. The feed unit is then turned off and the hydraulic follow-up system is turned on by the distributor 28, and the movement of the self-propelled trolley 1 is simultaneously activated. Moving the self-propelled trolley 1 at a constant speed and painting (cleaning) the surface. The rotation of the wheels of the self-propelled trolley 1 during its movement along the hull provides the contact and the necessary orientation of the working head with respect to the surface to be treated. The rotation of the self-propelled carriage 1 while moving along the surface to be treated is carried out automatically. The functions of the operator are to monitor the operation of the device. After the device has painted - cleaned - the strips on the hull 30 of the vessel along its length, the self-propelled trolley 1 stops. The hydraulic track of the system is turned off and turning on the distributor 28 rotates the working body for painting (cleaning) 180 torque hydraulic cylinder 5 relative to the axis of the power hydraulic cylinder 4 shaft. Then, turning on p spider 29, the working body is lifted (telescopic mast 2) to the required height. Subsequently, the working process is similar, but the surface is painted (cleaned) and the movement of the self-propelled carriage 1 is carried out in the opposite direction. The limitation of the angles of rotation of the framework is associated with the interaction of the framework of the working body during its pressing and movement on the painted surface 30. Thanks to the independent suspension of the frames 14, 15 and the ball bearings 17, the working body is able to move along the convex or concave surface of the hull of complex curvature.
