Description

Technical Field

[0001] The utility model relates to the field of brackets, and more particularly to a novel engine maintenance bracket. Background Art

[0002] Currently, when an engine needs to be inspected or placed, it is generally removed from the machine, cleaned, placed in a maintenance bracket for draining and inspection, and then reinstalled into the machine after the processing is completed.

[0003] Currently, disassembled engines are generally placed directly on the ground for inspection and repair. However, since the engine is cylindrical in shape, it is prone to rolling and is not easy to carry.

[0004] If the engine is to be placed in a mobile bracket, the engine connecting bar connected to the engine needs to be installed and fixed. Currently on the market, the mounting structure of the bracket to the engine connecting bar is relatively complicated, which is not convenient for workers to use and install quickly.

[0005] Therefore, it is necessary to propose a novel engine overhaul bracket that solves the above problems. Utility Model Content

[0006] The utility model provides a novel engine maintenance bracket in order to overcome at least one defect (shortcoming) of the above-mentioned prior art.

[0007] In order to solve the above technical problems, the technical solution of the present utility model is as follows: a new engine maintenance bracket includes a working ladder, a connecting base frame, a front support column and a rear support column;

[0008] A working ladder limiting portion is provided at the head end of the connecting chassis, and the working ladder is arranged on the working ladder limiting portion;

[0009] The front support column is arranged at the end of the connecting frame, and the rear support column is arranged at the intersection of the working ladder limit part and the connecting frame;
