Adjustable supporting device for ship stern tube bearing installation and using method

Abstract

The invention relates to the field of ship manufacturing tools, in particular to an adjustable supporting device for ship stern tube bearing installation and a using method. The device comprises a telescopic supporting rod, a middle body, long screws and a threaded transmission mechanism, wherein a middle supporting part is arranged on the upper portion of the middle body, and a middle sleeve is arranged on the lower portion of the middle body; the telescopic supporting rod penetrates through a middle sleeve on the lower portion of the middle body, and the middle body is located in the middle of the telescopic supporting rod; and the threaded transmission mechanism is installed on the lower portion of the middle body, the long screws are symmetrically arranged on the two sides of the threaded transmission mechanism in a back-to-back mode, the head ends of the long screws are fixedly arranged on the lower portion of one end of the telescopic supporting rod, and the tail ends of the long screws are in threaded fit transmission with the threaded transmission mechanism. The adjustable supporting device and the using method are novel in structural design, low in manufacturing cost, convenient to carry and operate, wide in application range and capable of accurately supporting a long screw rod to the center position of a tail shaft tube, and effectively improve the construction convenience and safety.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to an adjustable support device for installing a ship stern tube bearing and a use method thereof. Background technique [0002] At present, the stern tube device of civil ships mostly adopts oil lubrication system. The stern tube is equipped with front and rear stern bearings. The front and rear stern bearings are interference fit with the inner hole of the stern tube. Hundreds to thousands of KN. Nuts, bearing pressure plates, long screw rods, extended nuts, hollow oil pumps, support rods, end pressure plates and other tooling are used for installation. For details, refer to the appendix of the manual. figure 1 . [0003] First, two support rods are arranged in the stern tube, and at least two long threaded rods are connected with extension nuts, inserted into the stern tube and placed on the support rods. One end of the filament rod group is installed with an end pressure...

AI Technical Summary

Problems solved by technology

[0005] 1. The traditional support is made of wood, see the attached manual for details. figure 2 , the length cannot be adjusted, and the change in the inner diameter of the stern tube can only be made of wood supports, and because the inner diameter of the ship stern tube is generally large, the cost of remaking the wood supports is relatively high

[0006] 2. Wood supports or support rods must support the long threaded rods at the center of the stern tube, and the position where the support rods are set in the middle of the stern tube is made of steel plates, and the roundness is not high. The made wood supports cannot be well supported. Central location

[0007] 3. Due to the heavy weight of the long screw rod, in order to meet the strength requirements, the wooden strut must be thickened and thickened. It is cumbersome to carry it into the stern tube manually, and there may be a danger of injury, which brings a lot of inconvenience to the construction
