Description

Изобретение относится к окрасочной технике, в частности к оборудованию для окраски вагонов, цистерн, контейнеров и других крупногабаритных изделий, и может быть использовано в любой области промышленности.The invention relates to painting equipment, in particular to equipment for painting cars, tanks, containers and other bulky products, and can be used in any industry.

По основному авт. св. Ν' 757206 известна камера для окраски крупногабаритных изделий, содержащая каркас с двумя проемами для прохода изделий, каретку с приводом и установленный на ней поперек движения изделия ряд распылителей, которая снабжена поворотной П-обраёной рамой, охватывающей вагон, и вертикально установленными по обе стороны вагона рядами распылителем, а каретка установлена с возможностью перемещения по боковым балкам П-образной рамы и снабжена механизмом поворота [1J.According to the main author. St. Ν '757206, a chamber for painting large-sized products is known, comprising a frame with two openings for the passage of products, a carriage with a drive and a row of spray guns mounted on it across the movement of the product, which is equipped with a rotary U-shaped frame covering the car and vertically mounted on both sides of the car in rows with a spray, and the carriage is mounted to move along the side beams of the U-shaped frame and is equipped with a rotation mechanism [1J.

Недостатком этой камеры является невозможность окраски в ней днищ обра батываемых изделий, например вагонов.The disadvantage of this chamber is the impossibility of painting the bottoms of processed products, for example, wagons, in it.

Цель изобретения - обеспечение возможности окраски днища вагона.The purpose of the invention is the ability to paint the bottom of the car.

Для достижения этой цели камера для окраски крупногабаритных изделий снабжена установленной в нижней ее части вблизи П-образной рамы перпендикулярно направлению движения изделия направляющей, выполненной из трех секций, расположенных друг к другу с зазором для прохода колесной пары вагона, и установленными на направляющей с возможностью возвратно-поступательного перемещения двумя тележками с дополнительными распылителями.To achieve this goal, the camera for painting large-sized products is equipped with a guide installed in its lower part near the U-shaped frame perpendicular to the direction of movement of the product, made of three sections arranged to each other with a gap for the passage of the wheelset of the car, and mounted on the guide with the possibility of return - translational movement of two carts with additional sprayers.

Тележки могут быть выполнены трехосными, причем расстояние между их соседними осями больше зазора между секциями направляющей.Carts can be made triaxial, and the distance between their adjacent axes is greater than the gap between the sections of the guide.

. Такое выполнение устройства позволяет окрашивать днище вагона одновременно с окраской боковых стен и крыши при безостановочном прохождении вагона через камеру, при этом тележки с распылителями отводятся из зоны окраски при прохождении колесной пары через направляющую. Так как тележки имеют расстояние между осями больше, чем зазор между секциями направляющей, они могут беспрепятственно преодолевать этот зазор при отводе из зоны окраски и обратном перемещении.. This embodiment of the device allows you to paint the bottom of the car simultaneously with the coloring of the side walls and the roof during the non-stop passage of the car through the chamber, while the carts with sprays are removed from the paint zone when the wheelset passes through the guide. Since the trolleys have a distance between the axes more than the gap between the sections of the guide, they can freely overcome this gap when withdrawing from the paint zone and moving back.
