Background
With the advancement of modern construction of the country, market competition is more and more intense, and users have higher requirements on the quality of engineering machinery such as excavators, cranes and the like, and particularly, the comfort of a cab has higher requirements. Due to the fact that the tightness of a vehicle body is affected by deviation or damage of various links such as design, processing and assembly processes, leakage phenomena of different degrees occur when a cab of a few engineering machines is subjected to rain tests.
In addition, the poor tightness of the cab also can cause excessive noise at the driver position, so that physical and psychological health and working efficiency of the driver are greatly affected, and meanwhile, the noise limit value at the driver position of the earthmoving machine in the new standard of GB16710-2010 earthmoving machine noise limit is greatly reduced, so that great pressure and challenges are brought to the inside of the industry.
In construction machines such as excavators, a hydraulic hose or an electric harness extending from an operation lever in a cab is passed through a cab floor, and a through hole is formed in the cab floor. In addition, poor sealing of the cab door and window and the like also cause the reduction of the cab sealing and sound insulation performance. Due to sheet metal welding dimension processing errors, welding deformation, compression resilience of sealing rubber strips and the like, the cab skylight often has poor tightness on the front side and the left side and the right side. If the sealing treatment of the pipeline via hole and the skylight is improper, the sealing performance of a cab can be damaged, and the noise beside the ear of a driver is large, so that the overall quality of the engineering vehicle is further affected.
