Tank washing machine fastening supporting device, tank washing machine and ship

Abstract

The invention discloses a tank washing machine fastening supporting device, a tank washing machine and a ship. The tank washing machine fastening supporting device comprises a fastening sleeve assembly and a pull rod assembly, the fastening sleeve assembly is arranged on the outer side of a middle rod of the tank washing machine in a sleeving mode, and is adjacent to a tank washing nozzle arrangedon the end portion of the middle rod. The fastening sleeve assembly comprises an outer fastening sleeve and two semicircular inner fastening sleeves, the two semicircular inner fastening sleeves areconnected in an opposite-buckling mode, and the middle rod is arranged between the two inner fastening sleeves in a clamped mode. The outer fastening sleeve is arranged outside two inner fastening sleeves in a circular mode, and is detachably connected with two inner fastening sleeves by connecting pieces. One end of the pull rod of the pull rod assembly is connected with the outer fastening sleeve, and the other end of the pull rod of the pull rod assembly is connected with the tank wall. According to the tank washing machine fastening supporting device, the middle rod can be clamped by the fastening sleeve assembly, and the fastening sleeve assembly is fixedly connected with the tank wall by the pull rod assembly, fixed points on the middle rod are increased, the vibration amplitude of the middle rod is reduced, and an installation base is prevented from loosening.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a fastening support device for a tank washing machine, a tank washing machine and a ship. Background technique [0002] Tankers need to transport different goods in normal operation. When the cargo tank is changing to another kind of goods, the original storage liquid must be cleared to prevent the newly loaded goods from being mixed. At the same time, even if the same kind of goods are loaded, After using the cargo hold for a long time, there will be debris deposited on the structure of the cargo hold, which must be removed regularly; in addition, before entering the cargo hold for inspection or repair, the residual substances accumulated in the hold must also be removed. (including the volatile chemical gas in the cabin) is cleared to ensure safety. In order to realize the above functions, the tanker has set up a dedicated cargo tank washing system, among which the tank washing ...

AI Technical Summary

Problems solved by technology

For tankers with complex structures such as cargo oil tanks, in order to improve the tank washing effect, the tank washing nozzles are required to extend into a deeper position in the cargo tank. In this case, the tank washing machine needs to be equipped with a longer middle rod, which means caused the nozzle at the end of the middle rod to have a greater distance from the fastening point

When the tank washing nozzle of the tank washing machine is working, it not only needs to spray out the tank washing liquid with relatively high pressure, but also needs to make periodic selections of 360 degrees in the horizontal direction and 180 degrees in the up and down direction, so there will be vibrations in all directions. If the reaction thrust is too far away from the fastening point, the relative torque will also be large, which will easily cause a large vibration when the tank washing machine is working
