Description

Technical Field

[0001] The invention relates to the technical field of supporting tools, in particular to a universal medium- and high-speed diesel engine crankshaft supporting tool. Background Art

[0002] The crankshaft is the most important moving part on a medium- and high-speed diesel engine. Its lifting work is one of the most important installation links in a diesel engine. Considering the weight and volume of the diesel engine crankshaft, parts are easily damaged during the lifting process. In addition, a lot of preparation work needs to be done before the crankshaft is lifted. Therefore, a universal crankshaft support tool with convenience and convenience is very necessary. It can ensure that the crankshaft is effectively supported outside the engine and perform relevant preparations to avoid safety accidents.

[0003] Common crankshaft support tools are generally one-piece bracket structures, which are directly supported on the bottom of the crankshaft when in use. However, due to the different sizes of crankshafts, this method is very troublesome to replace when supporting crankshafts of different sizes. In addition, since the vertical bracket chassis is unstable, it is easy to roll over when supporting the crankshaft, which poses a great safety hazard and cannot meet the working requirements of the support. Therefore, a universal medium and high-speed diesel engine crankshaft support tool is proposed. Summary of the invention

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a universal medium- and high-speed diesel engine crankshaft supporting tool, comprising:

[0008] A bottom plate, a supporting column is fixedly connected to the middle position of the top of the bottom plate, and a Y-shaped bracket is installed on the top of the supporting column;

[0009] The rubber pad is installed on the inner side of the Y-shaped bracket. A bolt is installed at the middle position of the bottom of the Y-shaped bracket. A threaded hole is opened at the middle position of the top of the supporting column.

[0010] Preferably, the upper and lower parts of the left and right sides of the support column are both movably mounted with connecting arms through bearings, and the left and right sides of the support column are located in the middle of the lower connecting arm and are movably connected with a cylinder through a hinge seat, which facilitates the folding or extension of the connecting arm.

[0011] Preferably, the outer ends of the connecting arms are movably mounted with vertical brackets via bearings, the bottom ends of the vertical brackets are fixedly mounted with support plates, the top ends of the cylinders are movably connected to the inner upper sides of the vertical brackets via bearings, the vertical brackets and the support plates can be driven to unfold via the connecting arms, thereby providing auxiliary support to the left and right sides of the supporting columns, thereby preventing tipping or shaking during maintenance and measurement of the crankshaft.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the present invention provides a universal medium- and high-speed diesel engine crankshaft supporting tool, which has the following beneficial effects:

[0014] The universal medium- and high-speed diesel engine crankshaft supporting tool can be disassembled and assembled with the supporting column by rotating the Y-shaped bracket through the added bolts, which facilitates the replacement of Y-shaped brackets of different sizes to meet the support requirements of crankshafts of different sizes. The operation process is convenient and the replacement speed is fast. At the same time, after the crankshaft is clamped in the Y-shaped bracket, the movement of the connecting arm is driven by the extension and contraction of the cylinder, so that the connecting arm can drive the vertical bracket and the supporting plate to unfold, thereby providing auxiliary support to the left and right sides of the supporting column, preventing the phenomenon of overturning or shaking when the crankshaft is maintained and measured, and improving the safety of the support tool.
