Abstract

The invention provides a cover plate device which is detachably installed on the rear side surface of the cab shell and is used for maintaining an engine. The rear part of the cab shell is provided with an engine shell; an engine is installed in the cab shell; the rear side surface of the cab shell is opposite to the front side surface of the engine shell; a first opening is formed on the rear side surface of the cab shell; and the front side surface of the engine shell is provided with a second opening which is opposite to the first opening. The cover plate device comprises an installation part and a plugging part, wherein the installation part can be detachably installed and fixed to the periphery of the first opening from the inner part of the cab shell; the plugging part is fixed with the installation part; and when the installation part is fixed to the periphery of the first opening, the installation part is embedded with the first opening and the second opening and plugs the first opening and the second opening. The cover plate device can be used for simultaneously sealing the first opening and the second opening; and when the engine is to be maintained, one-time detachment is just carried out, and thereby, the procedures and time are saved.

Description

technical field [0001] The invention relates to a rear cover plate device of a cab housing of a building construction machine, in particular to a cover plate device detachably fixed on the rear side of the cab shell and used for engine maintenance.
