Engineering machine cab body framework, manufacturing method, cab and engineering machine

Abstract

The invention discloses an engineering machine cab body framework, a manufacturing method, a cab and an engineering machine. The engineering machine cab body framework comprises a steel structure frame with a plurality of stand columns. A fiber composite material reinforcing part (11) is connected to at least one stand column in a laid mode. Each fiber composite material reinforcing part (11) comprises a fiber composite material layer. At least parts of fibers in each fiber composite material reinforcing part (11) are in the length direction of the corresponding stand column. According to the engineering machine cab body framework, the rigidity of the steel structure frame is combined with the tenacity and the impacting absorption performance of fiber composite materials, the arrangement mode of the fiber composite material layers is originally innovated, and therefore effective performance optimization is achieved while the weight of the engineering machine cab is remarkably reduced.

Description

technical field [0001] The invention relates to a cab, in particular to a main frame of a construction machinery cab and a manufacturing method thereof. In addition, the invention also relates to an engineering machine and an engineering machine cab. Background technique [0002] Construction machinery, such as mobile cranes, concrete pump trucks, road rollers, etc., due to the complex working environment and harsh road conditions, the driving stability of the vehicle is poor, especially when the vehicle is running under load, which often leads to overturning. The accident happened, which seriously threatened the life safety of the driver. In order to protect the life safety of the driver in a rollover accident, a rollover protective structure generally needs to be installed on the cab of the existing construction machinery. [0003] At present, the performance evaluation of ROPS is mainly based on international and domestic standards such as ISO 3471:2008 "Laboratory Test...

AI Technical Summary

Problems solved by technology

[0010] Second, adopting traditional design methods to design series product cabs requires designing different structures, resulting in increased design costs and product cycles

[0011] Third, the cab of the existing cab is made of a single steel. In order to enhance the structural rigidity, too many reinforcement beams are added, resulting in a large weight

[0012] Fourth, in order to improve the strength and rigidity of the cab, special-shaped cross-section pipes are often used for the main load-bearing cab column and other pipe structures, which increases the manufacturing cost and processing difficulty
