Abstract
Description
Technical Field
[0001] The utility model relates to the field of engine maintenance equipment, in particular to a frame for engine maintenance and a carbon deposit removal device. Background Art
[0002] When the equipment in the engine compartment is repaired and maintained, a place is needed to install the repair equipment or place the commonly used repair tools. However, the existing engine compartment does not have a flat surface for installing the repair equipment and placing the repair tools, so the repair equipment and the placement of the repair tools need to be located outside the engine compartment.
[0003] Workers need to go back and forth many times to operate maintenance equipment or take maintenance tools, which is not conducive to improving workers' maintenance efficiency. In addition, since there is no place for workers' maintenance tools in the engine compartment, maintenance tools are easily left in the engine compartment by workers, causing damage to equipment in the engine compartment.
[0004] After long-term use, carbon deposits will form inside the engine, and it is necessary to clean the carbon deposits in the engine in time. The current cleaning method is to add a cleaning agent into the engine and fix one end of a rocker on the crankshaft of the engine. Then, the rocker is manually reciprocated to make the piston in the engine move up and down, so that the cleaning agent can fully contact the cylinder, piston and piston ring, thereby more fully removing the carbon deposits (especially the carbon deposits on the piston ring).
[0005] However, the swinging rocker needs to last for a sufficient time (about 2 hours) to completely remove the carbon deposits. At present, due to the manual reciprocating swinging rocker, one worker can only remove the carbon deposits from one engine, which has a low working efficiency and increases the labor intensity of the workers.
