Description

Technical Field

[0001] The utility model relates to the technical field of ship repair, in particular to a disassembly and assembly bracket for a multi-functional manually adjustable propeller. Background Technique

[0002] In the ship engine dock repair project, the press-fitting disassembly and assembly of the propeller is relatively important. If the propeller is not leveled during disassembly and assembly, it is very likely that problems will occur in the installation of the propeller, resulting in a maritime safety accident for the ship. Because the center distance of the propeller from the baseline is different for different ship types, and the distances between the front and rear ends of the propeller hub are inconsistent, different propeller disassembly and assembly brackets need to be made for the propeller press-fitting disassembly project. For this reason, we propose a multi-functional adjustable propeller disassembly and assembly bracket.

[0003] After retrieval, the patent with the Chinese patent publication number CN212172485U discloses a multi-functional adjustable propeller disassembly and assembly bracket, including a base. There are two groups of bases. Universal wheels are fixedly installed on the bottom surfaces of the two groups of bases. Electric telescopic rods are fixedly installed at the front and rear ends of the bottom surface of the base. A bracket is fixedly installed on the bottom surface of the electric telescopic rod. The cross-section of the bracket is an isosceles trapezoid structure, and the width of the bracket gradually increases from top to bottom. A chute is opened on the upper surface of the base. Openings are opened on one side of the two groups of bases away from each other. The openings are communicated with the chute. A moving frame is arranged on the upper surface of the base. The moving frame is a hollow triangular structure, and there are four groups of moving frames. In the utility model, the electric telescopic rod is controlled by a controller to extend so that the propeller fits the surface of the movable fixing block, and then the movable fixing block and the propeller are fixed through the threaded holes, achieving the application of a common bracket for different hub depths and different propeller diameters, and improving the efficiency of propeller disassembly.

[0004] The above patent has the following deficiencies: This bracket is elevated by an electric telescopic rod for fixing. However, in actual use, since the electric telescopic rod is an electric device, it is prone to failure. If a failure occurs, it will affect the normal operation. Therefore, a manual mechanical device is more reliable. In view of this, we propose a disassembly and assembly bracket for a multi-functional manually adjustable propeller.
