The elbow inner wall coating machine is characterized in that a travelling trolley (3) is arranged on the rack; one end of the chain is connected with the front end of the travelling trolley; the other end of the chain rounds the driving chain wheel and the driven chain wheel, and then is connected with the rear end of the travelling trolley; a flexible spray gun (6) is fixed to the travelling trolley; the rear section of the flexible spray gun can swing along the horizontal plane; two centering guides (8) are fixed to the front end of the flexible spray gun in a spaced manner; a paint bucket (11) with a paint pump is fixed at the lower part of the rack, and is communicated with the flexible spray gun through a powder supply pipe (4); a rigid air supply pipe (2) is arranged at the front section of the flexible spray gun; the rear of the rigid air supply pipe is fixedly connected with a flexible pipe (14); the rear of the flexible pipe is fixedly connected with a spray head (16); the flexible pipe and the spray head are externally connected with a hinge joint (15) consisting of a plurality of hinges in a sleeving manner; one end of the hinge joint is fixedly connected with the rigid air supply pipe through bolts (13); and the other end of the hinge joint is connected with the spray head in a sleeving manner.
Description
Technical field
The present invention relates to a kind of spraying equipment, particularly relate to a kind of elbow internal wall flush coater.
Background technology
It is known that start the commonly used inside coating of external oil and gas pipeline to improve pipeline transmission capacity from the 1950's, prevent inner wall corrosion, save power.Through years development, having formed highly developed straight tube steel pipe inner wall coating process technology, but be limited to the factor such as equipment and construction technology, the undercoating technology being directed to the special pieces such as bend pipe, threeway, reducer union is always a big difficult point.The commonly used hard tube spray gun of bend pipe spraying at present carries out manual application, and coating quality is difficult to ensure that and the limitation of operation is very big, and the bend pipe bigger for angle easily exists the dead angle area that cannot spray.
Summary of the invention
It is an object of the invention to overcome prior art not enough and the elbow internal wall flush coater of a kind of undercoating spraying that can be applicable to long-sweep ell is provided.Its concrete technical scheme is: elbow internal wall flush coater includes frame, motor reducer, drive sprocket, driven sprocket, chain, a walking dolly it is provided with in frame, chain one end connects with the front end of dolly, chain other end rear end with dolly after drive sprocket, driven sprocket connects, the flexible spray gun that a back segment can swing along the horizontal plane is fixed on dolly, the fore-end interval of flexible spray gun is fixed with two centralizers, one is fixed on frame lower with the paint can of paint pump, connects with flexibility spray gun for tube cell by one.
Described flexible spray gun is that a leading portion has a rigidity air supply pipe, an affixed flexible pipe after rigidity air supply pipe, is connected with after flexible pipe outside a shower nozzle, flexible pipe and shower nozzle and is socketed with a hinge joint being made up of several hinges, hinge is saved one end and is fixed on rigidity air supply pipe by bolt, and the other end is socketed with shower nozzle.
Described centralizer is the most symmetrically arranged four centralizer supporting legs, and centralizer supporting leg one end is fixed on hinge by screw thread, and the centralizer supporting leg other end is set with a roller by bearing pin.
In order to ensure levelness during flexible spray gun work, frame is provided with a carrying roller by flexible spray gun one side.
When using elbow internal wall flush coater of the present invention, first the bend pipe heating needing spraying is positioned on work platforms, internal diameter further according to bend pipe chooses suitable centralizer and is fixed on hinge joint, regulate the size of coating supply, guarantee that the thickness of coating is in the range of technological requirement, starting motor reducer, flexible spray gun is stretched into the other end in bend pipe to bend pipe by chain-driving walking dolly, starts compressed air and sends into coating powder and make walking dolly retreat the spraying of whole section of elbow internal wall.
Can be seen that from technical solution of the present invention, owing to have employed flexible spray gun structure, then it is equipped with different size of centralizer, so horizontal curvature motion can be carried out in bend pipe, and can effectively ensure that the centering effect of spray gun, it is possible to it is applicable to the elbow internal wall spraying of different tube diameters, curvature and angle.Fully achieve the goal of the invention of the undercoating spraying that present invention can apply to long-sweep ell.
