Description
Technical Field
The invention relates to the technical field of ship equipment installation, in particular to a detachable installation relay tool for a stern shaft and a using method of the detachable installation relay tool.
Background
In the installation process of the ship stern shaft, the ship stern shaft needs to penetrate through the whole stern tube, bearings are embedded in the front area and the rear area of the stern tube, babbitt metal on the bearings is expensive, meanwhile, a plurality of oil pipelines and a sensor protection pipeline penetrate through the whole stern tube, and the stern shaft stably penetrates through the stern tube and is a core element in the installation process of the stern shaft.
The stern shaft is installed and hoisted by virtue of the translation of calabash, and between the clearance 0.9-1.0mm of stern shaft and stern pipe, the ordinary 12600 of stern shaft weight supplyes 15000KG, and part has 20000KG more. After the stern shaft translates into the stern tube, along with continuous movement, the gravity center of the stern shaft is more difficult to control, and the instability of the stern shaft between the stern tubes is increased. Every time the gourd is pulled, the stern shaft is driven to shake up and down, left and right, and the risk of collision inside the stern shaft is increased. And the shaking of the stern shaft causes the damage risk of the babbitt metal of the inner bearing, an oil pipeline and a sensor protection tube to be greatly increased.
In order to facilitate the simultaneous stress of two ends in the hoisting process, the screw thread end of the stern shaft is used for lengthening a certain length, and the lengthened part is prolonged to the other end of the stern tube shortly after the stern shaft enters the stern tube, so that the hoisting operation is convenient to relay at the other end, and the hoisting work of the stern shaft is ensured. Due to different ship types, the used screw shaft extension bar and screw thread at the screw shaft end are changed continuously. The existing tools made by ships are only suitable for the same series of ship types, and the lengthening rods must be made again when the ship types are different, so that the ship types are many, the stern shaft relay tools made in large quantity cannot be reused, and the material waste is great. The connecting rod and the extension bar are connected through bolt fastening, and the process of tightening the bolt requires many people to cooperate simultaneously, thereby wasting time and energy and having low efficiency.
