Description
Technical Field
The invention belongs to the technical field of ship construction, and particularly relates to a cabin washing machine support positioning method.
Background
When a chemical tanker or a tanker is unloaded at a port and needs to load some other liquid cargo, the inner wall surface of the liquid cargo tank must be washed and cleaned. This requires the use of a tank washer apparatus, as shown in figure 1, which consists of a drive head 9 plus a long length of tank washing pipe 8, on which are mounted several nozzles 10 that can be rotated at an angle (e.g. 120 degrees) in the vertical plane. When the device works, high-pressure water flows through the driving head to drive the cabin washing pipe 8 to rotate in the horizontal plane direction by 360 degrees, and then the high-pressure water is sprayed to the inner surface of the cargo cabin from each nozzle 10 to achieve the purpose of high-pressure washing without dead angles in all directions.
Every cabin cleaning machine has 2~3 group's supports 4 according to the different needs of cabin cleaning pipe length, and support one end welding is on bulkhead 7, and one end is served and is installed circular subdivision formula pipe clamp 5 in addition, and the internal diameter of the soft liner of pipe clamp slightly is about 1mm than the cabin cleaning outside of tubes diameter, can prevent like this that the cabin cleaning pipe from rocking in the cabin can let its free rotation again. Therefore, all pipe clamp hoops of the tank washing machine have to keep high concentricity with a deck base 2 of the tank washing machine, otherwise, three supports 4 are restricted mutually, so that the abrasion loss of the tank washing pipe and the pipe clamp hoops is increased by a light person, the service life is shortened, and in a serious case, the tank washing pipe cannot be driven by working water to rotate and needs to be repositioned and installed.
Currently, the conventional method for positioning the cabin washing pipe bracket is a measurement method, as shown in fig. 2, a heavy hammer line is used to pass through the center of the deck base of the cabin washing machine downwards, then a measuring tape is used to repeatedly measure and adjust two-dimensional coordinates p (pb, pa) q (qd, qc) of the hoop center of the cabin washing machine bracket, so as to achieve the purpose, and finally pb = qd and pa = qc are required. The method has the most prominent disadvantages that the weight line positioning method can only be used in the stage when the ship body is horizontal (such as in a dock), and if the ship is on an inclined dock or wharf area, the weight line cannot be perpendicular to the base surface of the tank-washing machine on the top of the tank due to the inclined angle of the ship.
