Damping and noise reduction structure of cab and mining dump truck

Abstract

The invention discloses a damping and noise reduction structure of a cab and a mining dump truck and belongs to the field of machine manufacturing. The cab comprises a frame, a window, a truck door 7 and a cover 1, the cover 1, the window and the truck door 7 are arranged on the frame, and the cover 1 is made of sheet metal 1.2-2.0mm in thickness. The damping and noise reduction structure is characterized by further comprising a damping layer 2, the damping layer 2 is made by uniformly arranging damping materials on the cover 1 on the inner surface of the cab and the truck door 7 and is 2.0-4.0mm in thickness. Vibration and noise of the cab are comprehensively reduced by comprehensive means, technological means translation is good, the damping and noise reduction structure can be quickly popularized in the like products and is remarkable in effect.

Description

technical field [0001] The invention belongs to the field of mechanical equipment manufacturing, and relates to a shock-absorbing and noise-reducing structure, in particular to a cab's shock-absorbing and noise-reducing structure and a mining dump truck. Background technique [0002] Off-highway mining dump trucks are mainly used in large open-pit mines. The noise in the cab mainly comes from the noise outside the machine and the vibration noise of the cab itself. Excessive noise in the cab can easily cause driver fatigue, damage the driver's normal hearing, and affect driving comfort. Therefore, it is necessary to improve the design of the mining bicycle cab, effectively improve the noise level in the cab of the mine car, and solve the noise problem of the cab of the mine car. [0003] In the prior art, the cab-to-cab sealing design of the mining dump truck and the sound insulation and noise reduction treatment methods at the through holes are too simple, and are prone to ...

AI Technical Summary

Problems solved by technology

[0007] 3) The noise reduction and sound insulation methods in the cab are lacking, most of which are only treated with simple sound insulation sponge, and the noise reduction effect is limited;

[0008] 4) Poor sealing design of the cab itself, resulting in serious sound leakage;

[0009] 5) The sound insulation of the front window glass and the window glass of the cab is insufficient, and it is easy to become the bottleneck of high noise in the cab
