The invention discloses a ship shafting segmented tail pipe device and an installation method thereof. The ship shafting segmented tail pipe device comprises a tail pipe, wherein the tail pipe is divided into a front tail pipe and a rear tail pipe; the front ends of the front and rear tail pipes are connected with front and middle bearing bases by first and second loose joints; the rear ends of the front and rear tail pipes are connected with middle and rear bearing bases by first and second epoxy gland flanges. The installation method comprises the following steps: firstly installing an oil pipe and a cable pipe inside the tail pipe; installing the rear ends of the front and rear tail pipes on the middle and rear bearing bases by the first and second epoxy gland flanges; supporting the front ends of the front and rear tail pipes by a jig frame; hoisting a tail shaft and head and tail sealing parts; after the tail shaft is hoisted in place, dismounting the jig frame and installing the first and second loose joints. According to the ship shafting segmented tail pipe device disclosed by the invention, the tail pipe is configured as a segmented tail pipe, and then all segments of the tail pipe are connected by utilizing the loose joints, the epoxy gland flanges and axial and end face sealing parts, so that the installation efficiency and the cleaning efficiency are greatly improved.
Description
technical field [0001] The invention relates to the field of ship equipment, in particular to a ship shafting segmented stern tube device and an installation method thereof. Background technique [0002] There are mainly two types of traditional ship shafting stern tubes. The short stern tubes are prefabricated in the field or the segmented stern tubes are welded and joined in the field. These two types of traditional ship shafting stern tubes are finally welded into a monolith. Usually, the short shaft system is an integral type that is prefabricated by the short tailpipe in the inner field, while the long shaft system is connected as an integral type by on-site welding and splicing in the field of the segmental tailpipe, that is, the bearing body is installed on the shaft hub, The two ends of the pipe of the tail pipe are respectively welded on the axle hub. It is difficult to install and position the integral stern tube on the berth of the outfield, and it requires high...
