Description

Technical Field

[0001] This utility model belongs to the field of shipbuilding technology, specifically relating to a marine mechanical wall frame bearing seat made of seamless steel pipe instead of cast steel. Background Technology

[0002] In the shipbuilding industry, marine machinery bulkhead bearing housings are crucial components, as their performance directly affects the stable operation and overall safety of marine machinery. Traditionally, marine machinery bulkhead bearing housings are primarily made of cast steel.

[0003] While cast steel bearing housings possess a certain strength and toughness, meeting the basic load-bearing requirements of ship operation, they also have several significant drawbacks. Firstly, the production process of cast steel is complex, requiring multiple stages such as casting, demolding, cleaning, and heat treatment. This not only results in a long production cycle but also the potential for defects at each stage, increasing scrap rates and manufacturing costs. Secondly, the high density of cast steel makes bearing housings made from it relatively heavy.

[0004] For ships, excessively heavy components increase the overall weight of the ship, which leads to increased fuel consumption, reduced operating efficiency and economic benefits, and makes the bearing housings for ships inconvenient to lift and transport due to the lack of load-bearing parts. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present utility model adopts a technical solution as follows: a marine mechanical wall frame bearing seat made of seamless steel pipe instead of cast steel is provided, including a lower seat body, an upper seat body is provided on the upper surface of the lower seat body, a bearing body is provided on the inner side wall of the lower seat body, both the lower seat body and the upper seat body are made of seamless steel pipe casting, and a front end cover is provided on the front surface of the lower seat body.

[0006] A support plate is fixedly connected to the side surface of the lower seat. A horizontal plate is fixedly connected to the side surface of the support plate. A rotating column is symmetrically arranged on the upper surface of the horizontal plate. A lifting ring is fixedly connected to the side surface of the rotating column.

The four symmetrically arranged lifting rings can be connected to the lifting ropes during hoisting, making the whole device more stable during hoisting. Furthermore, the collars, connecting rods, and L-shaped locking blocks installed on the lifting rings cooperate with each other, allowing the L-shaped locking blocks to be locked into the connecting plate, making the upper and lower seats more secure after installation and reducing the possibility of oil leakage at the gaps.

[0008] The present invention is further configured such that the side surface of the bearing body contacts the upper seat body, the side surface of the bearing body is provided with a groove, and an oil passage hole is provided through the groove.

[0009] Through the above technical solution, the added lubricating oil can slide in the groove and enter the bearing body through the oil passage hole.

[0010] The present invention is further configured such that an oil injection hole is provided on the upper surface of the upper seat, and an oil guide groove is provided on the inner wall of the upper seat, and the oil injection hole is connected to the oil guide groove.

[0011] The above technical solution allows lubricating oil to be injected into the internal bearing body through the oil injection hole.

[0012] The present invention is further configured such that the side surface of the connecting rod is provided with threads, the side surface of the L-shaped locking block is movably connected to the connecting plate, and the upper surface of the pressure plate is in contact with the nut.

[0013] The present invention is further configured such that a limiting post is provided on the upper surface of the lower seat, a limiting hole is provided through the lower surface of the connecting plate, and a long bolt is threadedly connected through the upper surface of the upper seat.

[0014] Through the above technical solution, the limiting post and the limiting hole cooperate to guide the installation of the upper and lower seats.

[0015] The present invention is further configured such that the side surface of the limiting post contacts the limiting hole, the number of the lifting rings is four and they are symmetrically arranged, and the side surface of the long bolt is threadedly connected to the lower seat body.

[0016] The present invention is further configured such that a cooling chamber is provided inside the lower seat, a coolant inlet pipe is provided on the front surface of the lower seat, and a coolant outlet pipe is provided on the front surface of the lower seat.

[0017] The above technical solution allows coolant to be filled into the cooling chamber through the coolant inlet pipe, which is used to cool the device.

[0018] The present invention is further configured such that an oil drain pipe is provided on the rear surface of the lower seat, a sealing plug is provided inside the oil drain pipe, and a short bolt is threadedly connected to the front surface of the front end cover.

[0019] The beneficial effects of this utility model are as follows:

[0020] The use of seamless steel pipe casting for the upper and lower seats reduces the overall weight of the device, lowers operating costs, and helps improve the ship's fuel economy and navigation performance. Furthermore, the use of lifting rings, collars, connecting rods, L-shaped clips, and nuts during installation ensures a more secure fit, reducing the risk of oil leakage due to weak connections. The four symmetrically arranged lifting rings allow for connection to the lifting ropes during hoisting, providing leverage points and enhancing stability during lifting. Attached Figure Description
