Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0009] Such as figure 1 As shown, the rollover protection structure of the engineering vehicle cab of the present invention includes a frame and a bottom frame welded to each other, a right column 1 is welded between the rear frame and the bottom frame, and a door middle is welded between the upper frame and the bottom frame. The column 4 is welded with a transverse reinforcement column 3 and a reinforcing plate 2 between the door center column 4 and the rear frame. The right column 1, the door center column 4, the transverse reinforcement column 3 and the reinforcement plate 2 further enhance the overall strength of the cab and improve the safety performance of the cab overturning.

Abstract

The invention discloses a cab rollover protective structure, and belongs to the field of vehicle cabs. The cab rollover protective structure comprises frames and a bottom framework, wherein the frames and the bottom framework are welded together. A right stand column is welded between the rear frame and the bottom framework. A door center pillar is welded between the upper frame and the bottom framework. A transverse reinforcing column and a reinforcing plate are welded between the door center pillar and the rear frame. By the adoption of the structure, the cab rollover protective structure has the advantages that the right stand column, the door center pillar, the transverse reinforcing column and the reinforcing plate are additionally arranged compared with an existing cab frame, as a result, the overall strength of a cab is enhanced, and safety performance is improved.

Description
