PARKING MACHANISM OF TANK CLEANING MACHINE HAVING A PORTABLE RACK GEAR PART}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tank washer of a ship, the tank having a portable rack gear unit for reducing the installation cost of the tank washer for cleaning the inside of the tank after unloading liquid, solid, or powdered form and securing operational stability. A parking device for a washer.

Generally, tankers such as Crude Oil Tanker, Chemical Tanker, Product Carrier, Bulk Carrier, etc. are unloaded at the port and then inside the tank. In order to clean the inside of the tank, a tank washer is installed on the deck of the tank ship (DECK). The tank washer is installed so as to drill a hole in the deck and lower the washer pipe connected with the nozzle into the tank. The tank washer is sprayed with the washing liquid and the water into the tank to perform the washing operation.

However, when used in bulk carriers that mainly carry non-liquid cargo such as solids or powders, when the washing machine is fixed in a state where the washing machine is extended long into the tank, it may be caused by solid or powder cargoes filled in the tank. The problem occurs that the stand pipe and the nozzle portion of the washer is damaged

In order to solve this problem, the Republic of Korea Patent No. 1002409, the 'parking device of the tank cleaning device' to load the cargo to the top inside the tank by lifting and parking the tank washer when not using the washing machine It is starting.

1 is a configuration of the tank cleaning device 100 of the Republic of Korea Patent No. 1002409 described above, Figure 2 is a configuration of the parking device of the tank cleaning device of the Republic of Korea Patent No. 1002409, Figure 3 is a Republic of Korea Patent No. 1002409 A side sectional view of the tank washer installed on the deck.

Tank cleaning apparatus 100 of the Republic of Korea Patent No. 1002409 as shown in Figure 1 is an inlet 110 connected to the washing water supply pipe 104, the drive unit 120 is installed on the inlet 110, and It consists of a stand pipe 130 connected to the lower portion of the inlet 110 and a nozzle 140 installed at the end of the stand pipe 130. Here, an impeller is installed inside the inlet 110, and the drive unit 120 is operated by the rotational force of the impeller to rotate the nozzle 140 at the bottom horizontally and vertically by the drive unit 120 to spray the washing water. It is composed.

And the parking device of the tank cleaning device, as shown in Figure 2, one side fixing bracket 251 and the other side fixing bracket 253 is fixed to both sides of the opening hole 102 formed in the deck 101, The fixing bracket 250 to which the washing water supply pipe 104 is supported and fixed to the other fixing bracket 253 and the inlet connector flange 211 coupled to the inlet flange 111 of the washing device inlet 110 are provided.
