Description

Screw shaft channeling tool

Technical Field

The utility model belongs to the technical field of ships, and particularly relates to a propeller shaft shifting tool.

Background

In the process of installing the propeller shaft in the stern tube of the ship, the front end bearing and the rear end bearing are already installed in the stern tube of the ship in advance. The propeller shaft needs to be sequentially passed through a front end bearing and a rear end bearing located in the stern tube of the ship. In the process of penetrating through the front end bearing in the stern tube of the ship, the propeller shaft can be moved to a proper position by adopting tools such as a crane, so that the propeller shaft and the front end bearing are prevented from being damaged due to sliding friction; then in the shaft shifting process, when the propeller shaft moves to the rear end bearing position, the shaft head of the propeller shaft is still positioned in the stern tube of the ship, the position of the propeller shaft cannot be adjusted, and the rear end bearing and the propeller shaft are easily damaged.

Therefore, research and development of a propeller shaft channeling tool, which is used for assisting a propeller shaft to be installed in a ship stern tube through channeling, and avoiding damage to the ship stern tube, a bearing and the propeller shaft, is a technical problem to be solved urgently.

In this embodiment, a propeller shaft shifting tooling is related to, as shown in fig. 1, 2 and 3, including a connection assembly, an extension assembly and a hoisting member 300.

The extension assembly is connected to one end of the connection assembly.

The other end of the connecting assembly is used for being detachably connected with the end part of the propeller shaft.

As shown in fig. 1, 5 and 6, since the male screw portion is formed at the end of the propeller shaft, the female screw portion 121 is formed at the other end of the connection unit so that the connection unit is screwed with the propeller shaft by the female screw portion and the male screw portion in order to achieve detachable connection with the propeller shaft.

The lifting member 300 is attached to the extension assembly.

Specifically, the hoisting component 300, the extension component and the connection component are sequentially connected.

In this embodiment, the connection assembly includes a connection body 110 and a connection cavity 120 formed in the connection body 110.

The female screw part 121 is formed on the inner sidewall of the connection body 110.

Since the propeller shafts have different diameters, the connection assembly and the extension member 200 are designed to be detachably connected to each other so as to be able to fit the propeller shafts of different specifications.

So that when connecting with different propeller shafts, the connecting components with different specifications can be replaced.

In order to realize the detachable connection of the connecting component and the extending component, the connecting component and the extending component can be connected in a detachable manner by adopting a fastening piece.

In the present embodiment, as shown in fig. 5 and 6, a plurality of first screw holes 111 are provided at the end of the connection body 110 at intervals along the circumferential direction thereof.

The extension assembly includes an extension member 210 and an extension connecting member 220.

The extension connection member 220 is connected to an end of the extension member 210.

As shown in fig. 4, the connection extension member 220 is provided with a plurality of second screw holes 221 spaced apart along the circumference thereof.

The plurality of first screw holes 111 are in one-to-one correspondence with the plurality of second screw holes 221.

The first screw hole 111 and the second screw hole 221 are connected by a fastener 230. Thereby realizing the detachable connection of the extension component and the connection component.

In other embodiments, the connection assembly and the extension assembly may be removably connected in other ways.

In the present embodiment, in order to ensure that the extension member 210 has sufficient structural strength, the extension member 210 has a cylindrical structure extending in the circumferential direction of the propeller shaft.

Because the length of the propeller shaft is longer, and the weight is heavier, the weight range which can be carried by manpower is far exceeded, and therefore, in the process of installing the propeller shaft in a stern tube of a ship, the propeller shaft must be lifted by lifting equipment. Therefore, in the lifting process, the lifting device can be connected with the propeller shaft shifting tool, so that the propeller shaft can be indirectly lifted.

Thus, the lifting member 300 may employ a lifting lug plate.

Before the propeller shaft is installed, the connecting component is connected with the propeller shaft, after the propeller shaft passes through the front end bearing of the ship stern tube, the propeller shaft is continuously moved along the ship stern tube, when the propeller shaft does not move to the rear end bearing, the hoisting component 300 stretches out of the extending component, namely the ship stern tube, and the lifting equipment can be connected with the lifting lug plate, so that the height of the propeller shaft is adjusted, and the adjustment of the relative position of the propeller shaft and the rear end bearing is realized.

In this embodiment, since the weight of the propeller shaft is heavy, and the force application point of the hoisting device relative to the shaft shifting tool is located at the end of the tool, the length of the extension member 210 is long, and deformation is easy to occur, so the extension member 210 may adopt a cylindrical structure.

In addition, a plurality of reinforcing portions 240 may be provided along the circumferential direction of the extension member 210. The reinforcement 240 is simultaneously connected with the extension connection member 220.

Specifically, the reinforcing portion 240 may take the form of a rib plate.

The extension connection member 220 adopts a plate-like structure. The extension link 220 may take the same form as the cross section of the link assembly.

In the description of the above embodiments, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The foregoing is merely illustrative embodiments of the present utility model, and the scope of the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be covered by the present utility model, and the scope of the present utility model shall be defined by the appended claims.
