Embodiment Construction

[0038] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039] Such as Figure 1 to Figure 5 As shown, a bottom plate for construction machinery cab of the present invention includes an upper plate 1, a lower prestressed reinforcement plate 2 and a positioning plate 3 all made of steel plates. The upper plate 1 is welded on the top surface of the lower prestressed reinforced plate 2 , and the positioning plate 3 is welded on the bottom surface of the lower prestressed reinforced plate 2 . Through the stamping process, reinforcing ribs are formed on the surface of the lower prestressed reinforcing plate 2 , and structural prestress is formed inside the lower prestressed reinforcing plate 2 . The reinforcement ribs include transverse reinforcement ribs 4 and longitudinal reinforcement ribs 5 that criss-cross.

Abstract

The invention discloses a bottom plate for an engineering machine cab. The bottom plate comprises an upper-layer flat plate, a lower-layer prestress reinforcement plate and a locating plate, the upper-layer flat plate, the lower-layer prestress reinforcement plate and the locating plate are all made of steel plates, the upper-layer flat plate is welded to the top face of the lower-layer prestress reinforcement plate, and the locating plate is welded to the bottom face of the lower-layer prestress reinforcement plate. Through the stamping technology, reinforcement ribs are formed on the surface of the lower-layer prestress reinforcement plate, and structural prestress is formed in the lower-layer prestress reinforcement plate. According to the bottom plate, the problems that vibration and sound radiation of the flat bottom plate of a current traditional engineering machine cab are obvious, and the bending and torsion resisting capacity is insufficient can be solved.

Description

technical field [0001] The invention relates to a bottom plate of a driver's cab, in particular to a bottom plate for a construction machinery driver's cab. Background technique [0002] With the rapid development of the construction machinery industry and the establishment and improvement of the occupational health system for workers, the requirements for the control of vibration and noise of construction machinery have become more and more stringent. The vibration and noise characteristics of the construction machinery cab have a great impact on the physical and mental health and work efficiency of the cab personnel. Therefore, cab vibration and noise control has become an important aspect in the field of construction machinery research. [0003] During the working process of construction machinery, some external excitations such as road surface, hydraulic system, engine and drive train imbalance often cause vibration and noise in the cab, and the bottom plate of the cab ...
