Quick change device for lubricating oil of stern machine
Technical Field
The invention relates to the field of stern machines, in particular to a device for quickly replacing lubricating oil of a stern machine.
Background
Lubricating oil in the stern machine gear box needs to be changed on time according to navigation mileage and time, and the stern machine is inconvenient to disassemble, so the conventional oil change mode is to lift the ship and the stern machine to the shore, and oil is drained or refueled through the stern machine gear box oil drain plug screw, but the lifting of the ship is time-consuming and labor-consuming, high in cost and dangerous to some extent.
Disclosure of Invention
The invention aims to provide a device for quickly replacing lubricating oil of a stern machine, which is characterized in that a ship does not need to be hoisted to go ashore, the stern machine does not need to be disassembled, the lubricating oil in a gear box of the stern machine can be quickly drained or refueled on the ship, and the problems of time waste, labor waste and high cost of hoisting the ship are effectively solved.
The technical scheme of the invention is as follows: the utility model provides a stern machine lubricating oil quick replacement device, includes oil pump unit spare, hose part, oil duct, sealed apron and bellows, its characterized in that: one end of the hose part is connected with an oil storage chamber of the stern machine through an oil duct, the other end of the hose part is connected with an oil pump part, and the oil pump part is started to pump or refuel lubricating oil in a gear box of the stern machine.
The sealing cover plate is arranged on a ship board, the hose part and the sealing cover plate are connected through the corrugated pipe, and the joint of the hose part and the sealing cover plate and the corrugated pipe is locked through the clamp. The bellows on the one hand serves to seal between the hose part and the sealing cover plate and to prevent water from entering the hull. On the other hand, the length of the corrugated pipe is telescopic, so that the problem that the hose part is excessively bent in the lifting and falling processes of the stern machine is solved.
According to the invention, the hose part is provided with the first connector, the oil pump part is provided with the second connector, the oil path is smooth when the first connector and the second connector are connected, and the oil path is stopped when the first connector and the second connector are separated, so that oil leakage when the hose part and the oil pump part are disconnected is avoided.
According to the invention, the oil duct on the gear box is connected with the oil storage chamber of the stern machine, and when the oil cylinder tilts the stern machine to perform oil pumping work, the connection part of the oil duct and the oil storage chamber is positioned at the bottom of the oil storage chamber, so that lubricating oil can be pumped completely.
The invention has the beneficial effects that: the lifting device is simple in structure, convenient to operate and high in working efficiency, and can solve the problems of time waste, labor waste and high cost of lifting ships. The invention can be used for extracting the lubricating oil in the gear box of the stern machine more cleanly than the way of hoisting the ship to the shore, namely, the invention can remove impurities such as scrap iron, aluminum scraps and the like in the lubricating oil more cleanly and prolong the service life of the stern machine.

Detailed Description
It should be noted that, in the following paragraphs, possible directional terms including, but not limited to, "upper, lower, left, right, front, rear, inner and outer" etc. are used for convenience only to facilitate those skilled in the art to better understand the technical solution of the present invention, and should not be construed as limiting the scope or technical solution of the present invention.
It should also be noted that the terms "mounted," "connected," and "connected" are to be construed broadly unless otherwise specifically indicated and limited. For example, the connection can be fixed connection or detachable connection; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the creation of the present invention can be understood according to specific situations by those of ordinary skill in the art.
The technical solution of the present invention will be further described and illustrated with reference to the accompanying drawings and embodiments.
Referring to fig. 1, 2 and 3, a device for rapidly replacing lubricating oil of an aft engine includes an oil pump unit 1, a hose unit 2, an oil passage 3, a sealing cover plate 10 and a bellows 11. One end of the hose component 2 is connected with an oil storage chamber 5 of the stern machine through an oil duct 3 in a gear box 4, and the other end is connected with the oil pump component 1. The hose part 2 is provided with a first joint 12, the oil pump part 1 is provided with a second joint 13, the first joint 12 and the second joint 13 are connected to ensure that the oil path is smooth and the oil path is cut off when the first joint 12 and the second joint 13 are separated. The left end of the oil cylinder 6 is connected with the stern machine 7, the right end is fixed on the middle rail 8, the left end of the middle rail 8 is connected with the stern machine 7, the right end is fixed on the ship board 9, the oil cylinder 6 can tilt or fall the stern machine 7 when working, fig. 1 shows the state when the stern machine 7 tilts, and fig. 2 shows the state when the stern machine 7 falls. The sealing cover plate 10 is arranged on the ship board 9, the right end of the hose part 2 is connected with the sealing cover plate 10 through the corrugated pipe 11, the joint of the corrugated pipe 11 and the hose part 2 is locked through a clamp, on one hand, the corrugated pipe 11 prevents water outside the ship board 9 from entering the ship board 9, on the other hand, the length of the corrugated pipe 11 is telescopic, and the hose part 2 is prevented from being excessively bent in the rising and falling processes of the stern machine 7.
When the invention is in the oil pumping working state, as shown in figure 1, the oil cylinder 6 works to tilt the stern machine 7, and the oil pumping part 1 is restarted to pump the lubricating oil in the oil storage chamber 5, because the joint of the oil duct 3 and the oil storage chamber 5 is positioned at the bottom of the oil storage chamber 5, the oil pumping mode of the invention is cleaner than the mode of hoisting a ship to the shore to discharge the oil through the oil discharge plug on the gear box.
When the present invention is in the oiling working state, as shown in fig. 2, the oil cylinder 6 works to drop the stern engine 7, and the oil storage chamber 5 can be oiled by restarting the oil pump part 1. The reason why the stern device 7 is dropped during the refueling operation is to discharge the air in the oil storage chamber 5 and ensure the correct amount of lubricating oil to be filled.
When the invention is in the non-oil pumping or oil filling working state, as shown in figure 3, the first connector 12 and the second connector 13 can be disconnected, and the oil pump component 1 can be stored separately.
It should be noted that the structure of the stern engine 7, the middle gear 8 and the oil pump unit 1 in the above drawings are simplified for the convenience of understanding the present invention. In addition, the above drawings represent only preferred embodiments of the present invention and are not intended to limit the present invention, and those skilled in the art will appreciate that various modifications and changes may be made to the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
