Description

TECHNICAL FIELD

[0001] The utility model relates to the field of ship maintenance, especially propeller repair tooling. BACKGROUND

[0002] The propeller of the ship converts the rotating power of the engine into propulsive force to drive the ship to move through rotating in the water. The propeller is always immersed in the water from the beginning of the ship launching. The propeller is generally made of high-strength corrosion-resistant material, but long-term use will also cause the propeller to gradually damage. The propeller that can drive a large ship is also huge, and it is very inconvenient for maintenance personnel to repair it. SUMMARY

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide propeller repair tooling to solve the current pain points in this field.

[0004] The above technical purpose of the utility model is realized by the following technical scheme:

[0005] The propeller repair tooling comprises a lower support and a lifting support, the lower support and the lifting support each comprise a stand column, the top of the lifting support is fixedly installed with an operation platform, the top of the stand column of the lower support is fixedly installed with a fixed connecting piece, the fixed connecting piece is sleeved on the stand column of the lifting support, the bottom of the stand column of the lifting support is fixedly installed with a movable connecting piece, the movable connecting piece is sleeved on the stand column of the lower support, the lifting support can move up and down relative to the lower support, a row of positioning holes are arranged on all the stand columns of the lower support and the lifting support, one end of a chain is connected to the bottom of the fixed connecting piece and the movable connecting piece, the other end of the chain is fixedly installed with a plug bolt, and the plug bolt can be inserted into the positioning holes below the fixed connecting piece or the movable connecting piece.

[0006] The propeller repair tooling further comprises a board cart, and the lower support is fixedly installed on the board cart.

[0007] A climbing ladder is fixedly installed on the side of the lower support, the bottom of the climbing ladder is fixedly installed on the board cart, a lifting ladder is fixedly installed on the same side of the lifting support, and a guardrail is fixedly installed on the upper part of the lifting ladder.

[0008] A fence is arranged on the edge of the operation platform.

[0009] Compared with the prior art, the operation platform in the device can be lifted with the lifting support, the operation platform can be fixed at different heights by inserting the plug bolt into the positioning holes at different positions, and the two climbing ladders installed on the two supports can also be conveniently climbed after the height of the operation platform is changed.
